    "content": "= Spring AI Contributor Guidelines\n\nDo you have something you'd like to contribute to **Spring AI**?\nWe welcome pull requests, but ask that you carefully read this document first to understand how best to submit them;\nwhat kind of changes are likely to be accepted; and what to expect from the Spring team when evaluating your submission.\n\nPlease refer back to this document as a checklist before issuing any pull request; this will save time for everyone!\n\n== Code of Conduct\nThis project adheres to the Contributor Covenant https://github.com/spring-projects/spring-ai#coc-ov-file[code of conduct].\nBy participating, you  are expected to uphold this code. Please report unacceptable behavior to\nspring-code-of-conduct@pivotal.io.\n\n== Understand the basics\n\nNot sure what a *pull request* is, or how to submit one?  Take a look at GitHub's excellent documentation:\nhttps://help.github.com/articles/using-pull-requests/[Using Pull Requests] first.\n\n== Search GitHub ticket first; create an issue if necessary\n\nIs there already an issue that addresses your concern?  Search the\nhttps://github.com/spring-projects/spring-ai/issues[GitHub issue tracker] to see if you can find something similar.\nIf not, please create a new issue before submitting a pull request unless the change is truly trivial, e.g. typo fixes,\nremoving compiler warnings, etc.\n\n== Developer Certificate of Origin\n\nAll commits must include a __Signed-off-by__ trailer at the end of each commit message to indicate that the contributor agrees to the Developer Certificate of Origin.\nFor additional details, please refer to the blog post https://spring.io/blog/2025/01/06/hello-dco-goodbye-cla-simplifying-contributions-to-spring[Hello DCO, Goodbye CLA: Simplifying Contributions to Spring].\n\n== Fork the Repository\n\n1. Go to https://github.com/spring-projects/spring-ai[https://github.com/spring-projects/spring-ai]\n2. Hit the \"fork\" button and choose your own GitHub account as the target\n3. For more detail see https://help.github.com/articles/fork-a-repo/[Fork A Repo].\n\n== Setup your Local Development Environment\n\n1. `git clone --recursive git@github.com:<your-github-username>/spring-ai.git`\n2. `cd spring-ai`\n3. `git remote show`\n_you should see only 'origin' - which is the fork you created for your own GitHub account_\n4. `git remote add upstream git@github.com:spring-projects/spring-ai.git`\n5. `git remote show`\n_you should now see 'upstream' in addition to 'origin' where 'upstream' is the SpringIO repository from which releases are built_\n6. `git fetch --all`\n7. `git branch -a`\n_you should see branches on origin as well as upstream, including 'main'_\n\n== A Day in the Life of a Contributor\n\n* _Always_ work on topic branches (Typically use the GitHub issue ID as the branch name).\n- For example, to create and switch to a new branch for issue GH-123: `git checkout -b GH-123`\n* You might be working on several different topic branches at any given time, but when at a stopping point for one of those branches, commit (a local operation).\n* Please follow the \"Commit Guidelines\" described in\nhttps://git-scm.com/book/ms/v2/Distributed-Git-Contributing-to-a-Project[this chapter of Pro Git].\n* Then to begin working on another issue (say GH-101): `git checkout GH-101`. The _-b_ flag is not needed if that\nbranch already exists in your local repository.\n* When ready to resolve an issue or to collaborate with others, you can push your branch to origin (your fork),\ne.g.: `git push origin GH-123`\n* If you want to collaborate with another contributor, have them fork your repository (add it as a remote) and\n`git fetch <your-username>` to grab your branch.\nAlternatively, they can use `git fetch --all` to sync their local state with all of their remotes.\n* If you grant that collaborator push access to your repository, they can even apply their changes to your branch.\n* When ready for your contribution to be reviewed for potential inclusion in the main branch of the canonical\nspring-ai repository (what you know as 'upstream'), issue a pull request to the SpringSource repository\n(for more detail, see https://help.github.com/articles/using-pull-requests/[Using pull requests]).\n* The project lead may merge your changes into the upstream main branch as-is, he may keep the pull request open yet\nadd a comment about something that should be modified, or he might reject the pull request by closing it.\n* A prerequisite for any pull request is that it will be cleanly merge-able with the upstream main's current state.\n**This is the responsibility of any contributor.**\nIf your pull request cannot be applied cleanly, the project lead will most likely add a comment requesting that you make\nit merge-able.\nFor a full explanation, see https://git-scm.com/book/en/Git-Branching-Rebasing[the Pro Git section on rebasing].\nAs stated there: _\"> Often, you’ll do this to make sure your commits apply cleanly on a remote branch — perhaps in a\nproject to which you’re trying to contribute but that you don’t maintain.\"_\n\n== Keeping your Local Code in Sync\n* As mentioned above, you should always work on topic branches (since 'main' is a moving target). However, you do want\nto always keep your own 'origin' main branch in sync with the 'upstream' main.\n* Within your local working directory, you can sync up all remotes' branches with: `git fetch --all`\n* While on your own local main branch: `git pull upstream main` (which is the equivalent of fetching upstream/main\nand merging that into the branch you are in currently)\n* Now that you're in sync, switch to the topic branch where you plan to work, e.g.: `git checkout -b GH-123`\n* When you get to a stopping point: `git commit`\n* If changes have occurred on the upstream/main while you were working you can sync again:\n- Switch back to main: `git checkout main`\n- Then: `git pull upstream main`\n- Switch back to the topic branch: `git checkout GH-123` (no -b needed since the branch already exists)\n- Rebase the topic branch to minimize the distance between it and your recently synced main branch: `git rebase main`\n(Again, for more detail see https://git-scm.com/book/en/Git-Branching-Rebasing[the Pro Git section on rebasing]).\n* **Note** You cannot rebase if you have already pushed your branch to your remote because you'd be rewriting history\n(see **'The Perils of Rebasing'** in the article).\nIf you rebase by mistake, you can undo it as discussed\nhttps://stackoverflow.com/questions/134882/undoing-a-git-rebase[in this StackOverflow discussion].\nOnce you have published your branch, you need to merge in the main rather than rebasing.\n* Now, if you issue a pull request, it is much more likely to be merged without conflicts.\nMost likely, any pull request that would produce conflicts will be deferred until the issuer of that pull request makes\nthese adjustments.\n* Assuming your pull request is merged into the 'upstream' main, you will actually end up pulling that change into\nyour own main eventually, and at that time, you may decide to delete the topic branch from your local repository and\nyour fork (origin) if you pushed it there.\n- to delete the local branch: `git branch -d GH-123`\n- to delete the branch from your origin: `git push origin :GH-123`\n\n== Maintain a linear commit history\n\nWhen merging to main, the project __always__ uses fast-forward merges.\nWhen issuing pull requests, please ensure that your commit history is linear.\nFrom the command line you can check this using:\n\n----\ngit log --graph --pretty=oneline\n----\n\nAs this may cause lots of typing, we recommend creating a global alias, e.g. `git logg` for this:\n\n----\ngit config --global alias.logg 'log --graph --pretty=oneline'\n----\n\nThis command, will provide the following output, which in this case shows a nice linear history:\n\n----\n* c129a02e6c752b49bacd4a445092a44f66c2a1e9 INT-2721 Increase Timers on JDBC Delayer Tests\n* 14e556ce23d49229c420632cef608630b1d82e7d INT-2620 Fix Debug Log\n* 6140aa7b2cfb6ae309c55a157e94b44e5d0bea4f INT-3037 Fix JDBC MS Discard After Completion\n* 077f2b24ea871a3937c513e08241d1c6cb9c9179 Update Spring Social Twitter to 1.0.5\n* 6d4f2b46d859c903881a561c35aa28df68f8faf3 INT-3053 Allow task-executor on <reply-listener/>\n* 56f9581b85a8a40bbcf2461ffc0753212669a68d Update Spring Social Twitter version to 1.0.4\n----\n\nIf you see intersecting lines, that usually means that you forgot to rebase you branch.\nAs mentioned earlier, **please rebase against main** before issuing a pull request.\n\n== Run Formatting Checks and Make Sure the Build Passes\n\nBefore opening a pull request, make sure that the following full build passes locally. As a side effect of that build, some files may get re-formatted to\nautomatically adhere to the conventions used in the project (see below). Be sure to commit those reformats before opening a PR if that happens.\n\n[source,shell]\n----\n./mvnw package\n----\n\n=== Source Code Style\n\nSpring AI source code checkstyle tries to follow the checkstyle guidelines used by the core Spring Framework project with some exceptions.\nThe wiki pages\nhttps://github.com/spring-projects/spring-framework/wiki/Code-Style[Code Style] and\nhttps://github.com/spring-projects/spring-framework/wiki/IntelliJ-IDEA-Editor-Settings[IntelliJ IDEA Editor Settings]\ndefine the source file coding standards we use along with some IDEA editor settings we customize.\n\n== Mind the whitespace\n\nPlease carefully follow the whitespace and formatting conventions already present in the framework.\n\n1. Tabs, not spaces\n2. Unix (LF), not DOS (CRLF) line endings\n3. Eliminate all trailing whitespace\n4. Wrap Javadoc at 90 characters\n5.

The project was founded with the belief that the next wave of Generative AI applications will not be only for Python developers but will be ubiquitous across many programming languages.\n\nYou can check out the blog post [Why Spring AI](https://spring.io/blog/2024/11/19/why-spring-ai) for additional motivations.\n\nThis is a high level feature overview.\nYou can find more details in the [Reference Documentation](https://docs.spring.io/spring-ai/reference/)\n\n* Support for all major [AI Model providers](https://docs.spring.io/spring-ai/reference/api/index.html) such as Anthropic, OpenAI, Microsoft, Amazon, Google, and Ollama. Supported model types include:\n  - [Chat Completion](https://docs.spring.io/spring-ai/reference/api/chatmodel.html)\n  - [Embedding](https://docs.spring.io/spring-ai/reference/api/embeddings.html)\n  - [Text to Image](https://docs.spring.io/spring-ai/reference/api/imageclient.html)\n  - [Audio Transcription](https://docs.spring.io/spring-ai/reference/api/audio/transcriptions.html)\n  - [Text to Speech](https://docs.spring.io/spring-ai/reference/api/audio/speech.html)\n  - [Moderation](https://docs.spring.io/spring-ai/reference/api/index.html#api/moderation)\n  - **Latest Models**: GPT-5, and other cutting-edge models for advanced AI applications.\n* Portable API support across AI providers for both synchronous and streaming options. Access to [model-specific features](https://docs.spring.io/spring-ai/reference/api/chatmodel.html#_chat_options) is also available.\n* [Structured Outputs](https://docs.spring.io/spring-ai/reference/api/structured-output-converter.html) - Mapping of AI Model output to POJOs.\n* Support for all major [Vector Database providers](https://docs.spring.io/spring-ai/reference/api/vectordbs.html) such as *Apache Cassandra, Azure Vector Search, Chroma, Elasticsearch, Milvus, MongoDB Atlas, MariaDB, Neo4j, Oracle, PostgreSQL/PGVector, Pinecone, Qdrant, Redis, and Weaviate*.\n* Portable API across Vector Store providers, including a novel SQL-like [metadata filter API](https://docs.spring.io/spring-ai/reference/api/vectordbs.html#metadata-filters).\n* [Tools/Function Calling](https://docs.spring.io/spring-ai/reference/api/tools.html) - permits the model to request the execution of client-side tools and functions, thereby accessing necessary real-time information as required.\n* [Observability](https://docs.spring.io/spring-ai/reference/observability/index.html) - Provides insights into AI-related operations.\n* Document injection [ETL framework](https://docs.spring.io/spring-ai/reference/api/etl-pipeline.html) for Data Engineering.\n* [AI Model Evaluation](https://docs.spring.io/spring-ai/reference/api/testing.html) - Utilities to help evaluate generated content and protect against hallucinated response.\n* [ChatClient API](https://docs.spring.io/spring-ai/reference/api/chatclient.html) - Fluent API for communicating with AI Chat Models, idiomatically similar to the WebClient and RestClient APIs.\n* [Advisors API](https://docs.spring.io/spring-ai/reference/api/advisors.html) - Encapsulates recurring Generative AI patterns, transforms data sent to and from Language Models (LLMs), and provides portability across various models and use cases.\n* Support for [Chat Conversation Memory](https://docs.spring.io/spring-ai/reference/api/chatclient.html#_chat_memory) and [Retrieval Augmented Generation (RAG)](https://docs.spring.io/spring-ai/reference/api/chatclient.html#_retrieval_augmented_generation).\n* Spring Boot Auto Configuration and Starters for all AI Models and Vector Stores - use the [start.spring.io](https://start.spring.io/) to select the Model or Vector-store of choice. \n\n## Getting Started\n\nPlease refer to the [Getting Started Guide](https://docs.spring.io/spring-ai/reference/getting-started.html) for instruction on adding your dependencies.\n\n## Project Resources\n\n* [Documentation](https://docs.spring.io/spring-ai/reference/)\n* [Issues](https://github.com/spring-projects/spring-ai/issues)\n<!-- * [Discussions](https://github.com/spring-projects/spring-ai/discussions) - Go here if you have a question, suggestion, or feedback! -->\n* [Awesome Spring AI](https://github.com/spring-ai-community/awesome-spring-ai) - A curated list of awesome resources, tools, tutorials, and projects for building generative AI applications using Spring AI\n* [Spring AI Examples](https://github.com/spring-projects/spring-ai-examples) contains example projects that explain specific features in more detail.\n* [Spring AI Community](https://github.com/spring-ai-community) - A community-driven organization for building Spring-based integrations with AI models, agents, vector databases, and more.\n\n## Breaking changes\n\n* Refer to the [upgrade notes](https://docs.spring.io/spring-ai/reference/upgrade-notes.html) to see how to upgrade to 1.0.0.M1 or higher.\n\n## Cloning the repo\n\nThis repository contains [large model files](https://github.com/spring-projects/spring-ai/tree/main/models/spring-ai-transformers/src/main/resources/onnx/all-MiniLM-L6-v2).\nTo clone it you have to either:\n\n- Ignore the large files (won't affect the spring-ai behaviour) :  `GIT_LFS_SKIP_SMUDGE=1 git clone git@github.com:spring-projects/spring-ai.git`.\n- Or install the [Git Large File Storage](https://git-lfs.com/) before cloning the repo.\n\n\n## Building\n\nThe project targets and build artifacts compatible with Java 17+, but requires JDK 21\nto build. This is enforced by the maven enforcer plugin.\n\nTo build with running unit tests\n\n```shell\n./mvnw clean package\n```\n\nTo build including integration tests.\n\n```shell\n./mvnw clean verify -Pintegration-tests\n```\n\nNote that you should set API key environment variables for OpenAI or other model providers before running.  If the API key isn't set for a specific model provider, the integration test is skipped.\n\nTo run a specific integration test allowing for up to two attempts to succeed.  This is useful when a hosted service is not reliable or times out.\n```shell\n./mvnw -pl vector-stores/spring-ai-pgvector-store -am -Pintegration-tests -Dfailsafe.failIfNoSpecifiedTests=false -Dfailsafe.rerunFailingTestsCount=2 -Dit.test=PgVectorStoreIT verify\n```\n\n### Integration Tests\nThere are many integration tests, so it often isn't realistic to run them all at once.\n\nA quick pass through the most important pathways that runs integration tests for\n\n* OpenAI models \n* OpenAI autoconfiguration\n* PGVector\n* Chroma\n\ncan be done with the profile `-Pci-fast-integration-tests` and is used in the main CI build of this project.\n\nA full integration test is done twice a day in the [Spring AI Integration Test Repository](https://github.com/spring-projects/spring-ai-integration-tests)\n\nOne way to run integration tests on part of the code is to first do a quick compile and install of the project\n\n```shell\n./mvnw clean install -DskipTests -Dmaven.javadoc.skip=true\n```\nThen run the integration test for a specific module using the `-pl` option\n\n```shell\n./mvnw verify -Pintegration-tests -pl spring-ai-spring-boot-testcontainers\n```\n\n### Documentation\n\nTo build the docs\n```shell\n./mvnw -pl spring-ai-docs antora\n```\n\nThe docs are then in the directory `spring-ai-docs/target/antora/site/index.html`\n\n### Formatting the Source Code\n\nThe code is formatted using the [java-format plugin](https://github.com/spring-io/spring-javaformat) as part of the build. Correct\nformatting is enforced by CI.\n\n### Updating License Headers\n\nTo update the year on license headers using the [license-maven-plugin](https://oss.carbou.me/license-maven-plugin/#goals)\n```shell\n./mvnw license:update-file-header -Plicense\n```\n### Javadocs\n\nTo check javadocs using the [javadoc:javadoc](https://maven.apache.org/plugins/maven-javadoc-plugin/)\n```shell\n./mvnw javadoc:javadoc\n```\n\n#### Source Code Style\n\nSpring AI source code checkstyle tries to follow the checkstyle guidelines used by the core Spring Framework project with some exceptions.\nThe wiki pages\n[Code Style](https://github.com/spring-projects/spring-framework/wiki/Code-Style) and\n[IntelliJ IDEA Editor Settings](https://github.com/spring-projects/spring-framework/wiki/IntelliJ-IDEA-Editor-Settings)\ndefine the source file coding standards we use along with some IDEA editor settings we customize.\n\nRun checkstyle manually:\n```shell\n./mvnw process-sources -P checkstyle-check\n```\n\n## Contributing\n\nYour contributions are always welcome! Please read the [contribution guidelines](CONTRIBUTING.adoc) first.\n"

    "content": "# Migration Guide: Spring AI Google GenAI Autoconfiguration\n\n## Overview\n\nThis guide helps you migrate from the old Vertex AI-based autoconfiguration to the new Google GenAI SDK-based autoconfiguration.\n\n## Starter Dependencies\n\nSpring AI provides separate starters for Google GenAI functionality:\n\n### Chat Functionality\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-google-genai</artifactId>\n    <version>1.1.0-SNAPSHOT</version>\n</dependency>\n```\n\n### Embedding Functionality\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-google-genai-embedding</artifactId>\n    <version>1.1.0-SNAPSHOT</version>\n</dependency>\n```\n\n**Note**: If you need both chat and embedding capabilities, include both starters in your project. The starters are designed to be used independently or together based on your requirements.\n\n## Key Changes\n\n### 1. Property Namespace Changes\n\nOld properties:\n```properties\nspring.ai.vertex.ai.gemini.project-id=my-project\nspring.ai.vertex.ai.gemini.location=us-central1\nspring.ai.vertex.ai.gemini.chat.options.model=gemini-pro\nspring.ai.vertex.ai.embedding.text.options.model=textembedding-gecko\n```\n\nNew properties:\n```properties\n# For Vertex AI mode\nspring.ai.google.genai.project-id=my-project\nspring.ai.google.genai.location=us-central1\nspring.ai.google.genai.chat.options.model=gemini-2.0-flash\n\n# For Gemini Developer API mode (new!)\nspring.ai.google.genai.api-key=your-api-key\nspring.ai.google.genai.chat.options.model=gemini-2.0-flash\n\n# Embedding properties\nspring.ai.google.genai.embedding.project-id=my-project\nspring.ai.google.genai.embedding.location=us-central1\nspring.ai.google.genai.embedding.text.options.model=text-embedding-004\n```\n\n### 2. New Authentication Options\n\nThe new SDK supports both:\n- **Vertex AI mode**: Using Google Cloud credentials (same as before)\n- **Gemini Developer API mode**: Using API keys (new!)\n\n### 3. Removed Features\n\n- `transport` property is no longer needed\n- Multimodal embedding autoconfiguration has been removed (pending support in new SDK)\n\n### 4. Bean Name Changes\n\nIf you were autowiring beans by name:\n- `vertexAi` → `googleGenAiClient`\n- `vertexAiGeminiChat` → `googleGenAiChatModel`\n- `textEmbedding` → `googleGenAiTextEmbedding`\n\n### 5. Class Changes\n\nIf you were importing classes directly:\n- `com.google.cloud.vertexai.VertexAI` → `com.google.genai.Client`\n- `org.springframework.ai.vertexai.gemini.*` → `org.springframework.ai.google.genai.*`\n\n## Migration Steps\n\n1. Update your application properties:\n   - Replace `spring.ai.vertex.ai.*` with `spring.ai.google.genai.*`\n   - Remove any `transport` configuration\n\n2. If using API key authentication:\n   - Set `spring.ai.google.genai.api-key` property\n   - Remove project-id and location for chat (not needed with API key)\n\n3. Update any custom configurations or bean references\n\n4. Test your application thoroughly\n\n## Environment Variables\n```bash\nexport GOOGLE_CLOUD_PROJECT=my-project\nexport GOOGLE_CLOUD_LOCATION=us-central1\n```\n\nNew (additional option):\n```bash\nexport GOOGLE_API_KEY=your-api-key\n```\n\n## Backward Compatibility\n\nThe old autoconfiguration module is still available but deprecated. We recommend migrating to the new module as soon as possible."

    "path": "design/01-null-safety.adoc",
    "content": "= Design Document 01 - Null Safety\n\nThis document is a quick reference for contributors to learn how to properly annotate the code base with JSpecify annotations. It can be seen as a TL,DR version of this https://docs.spring.io/spring-framework/reference/core/null-safety.html[Spring reference].\n\nSome sections of this document are of special interest when it comes to dealing with patterns present in the Spring AI codebase, such as `@ConfigurationProperties` and builders.\n\n== Problems\nThe \"billion dollar mistake\" is well known, and Spring AI 2.0 aligns with the rest of the Spring portfolio in its use of JSpecify annotations to express (non-)nullability of its APIs.\n\n\n== Solution\nSpring AI uses https://github.com/spring-projects/spring-ai/blob/a8d11421c9605c2eef609535448a94c5104960ed/pom.xml#L470-L531[JSpecify + NullAway + ErrorProne] to enforce nullability checks.\n\nFor consistency in the Spring AI codebase, the granularity at which null safety is enabled is the package, and only production code is annotated (test code is not).\nAny new package should be annotated with `@NullMarked`, like so:\n\n[source,java]\n----\nimport org.jspecify.annotations.NullMarked;\n\n@NullMarked\npackage org.springframework.ai.foo;\n----\nFrom there on, any element in that package assumes non-null type usage by default (for its own members).\n\nNOTE: As a reminder, packages in java are NOT hierarchical. This means that `org.springframework.ai.foo.bar` is NOT a \"sub-package\" of `org.springframework.ai.foo` and thus needs annotating on its own.\n\nAnnotating the codebase only gives hints to the compiler that something can/cannot be null. But nothing prevents consuming code to pass `null` if the build infrastructure of consuming code does not enforce JSpecify semantics. To protect users from such errors, it is still advisable to assert nullability as soon as possible, for example in object constructors:\n[source, java]\n----\nimport org.springframework.util.Assert;\n\n// in a @NullMarked package\npublic class MyThing {\n\n\t// bar and foo are assumed to be non-null\n    public MyThing(String bar, Foo foo) {\n        Assert.notNull(bar, \"bar should not be null\");\n        Assert.notNull(foo, \"foo should not be null\");\n        this.bar = bar;\n        this.foo = foo;\n        ...\n    }\n}\n----\n\nNOTE: `Assert.notNull()` throws an `IllegalArgumentException` when the provided value is `null`. As such, it is applicable for _e.g._ constructors where indeed tested values are _parameters_ to the method. For other use cases, _e.g._ builders, prefer to use `Assert.state(something != null, \"message\")`.\n\nWhen a value _could_ be `null`, annotate it with `@Nullable`. This applies to parameters, fields and even generic components (see below).\n\n[source, java]\n----\nimport org.springframework.util.Assert;\nimport org.jspecify.annotations.Nullable;\n\n// in a @NullMarked package\npublic class MyThing {\n\n    // bar and foo are assumed to be non-null\n    public MyThing(@Nullable String bar, Foo foo) {\n        Assert.notNull(foo, \"foo should not be null\");\n        this.bar = bar;\n        this.foo = foo;\n        ...\n    }\n}\n----\n\nAs a reminder, there is no need to annotate `Foo` as `@NonNull`, since it is the default once the enclosing scope (in our case the package) is annotated with `@NullMarked`.\n\nIt is important to understand that the thing being annotated is the so-called https://jspecify.dev/docs/user-guide/#type-use-annotation-syntax[type-use], and not the field or method itself. What this means is that for fields, the syntax to use is\n[source, java]\n----\n// in a @NullMarked package\npublic class MyThing {\n\n    private @Nullable Foo foo;\n}\n----\n\nand not\n[source, java]\n----\n// in a @NullMarked package\npublic class MyThing {\n\n    @Nullable private Foo foo;\n}\n----\n\nSimilarly, for method return types, use\n[source, java]\n----\n// in a @NullMarked package\npublic class MyThing {\n\n    public @Nullable Foo something() {\n        ...\n        return null;\n    }\n}\n----\nand not\n[source, java]\n----\n// in a @NullMarked package\npublic class MyThing {\n\n    @Nullable\n    public Foo something() {\n        ...\n        return null;\n    }\n}\n----\n\nAs a rule of thumb, the annotation should be placed closest to the thing it expresses the nullability of:\n\n* `java.util.Map.@Nullable Entry` renders the _entry_ nullable (not the map),\n* `@Nullable String[]` is a (non-null) array of nullable Strings,\n* `String @Nullable []` is a nullable array of (non-null) Strings,\n* _etc._\n\n=== Nullability and API design considerations\nIt is generally better to prefer non-nullable data and, failing to do that, to control the reach of nullable data. What this means in practice is that it is commonly ok to\n\n* initialize collections and arrays to empty structures instead of `null`. This allows iteration without having to think whether to handle `null` or not,\n* if B depends on A, it is better to prevent `null` from \"escaping\" out of A. The burden to check for `null` should reside on A, not on B, if possible.\n\n=== Nullability and `@ConfigurationProperties`\nSpring Boot `@ConfigurationProperties` classes should be annotated using the following rationale, given that Boot will never inject a `null` value as a property:\n\n* if the property field is initialized with a default value, then a `null` value can never creep in. Thus nothing needs to be done (non nullable by default),\n* if the property field does *not* have a default value, then obviously the getter needs to also be annotated with `@Nullable` (and the configuration class that uses the `@ConfigurationProperties` class is responsible for checking the value). Even though the setter will never be invoked with `null`, our practice is to annotate the setter as `@Nullable` nevertheless, because the symetry between getter and setter allows Kotlin to correctly mark the property as nullable.\n\n=== Nullability and the Builder pattern\nTODO\n\n=== User Impact\nChecks are only performed in scopes that are annotated as `@NullMarked`.\n\nWhat this means is that if consuming code does not leverage JSpecify annotations (both via annotating the consuming code and configuring the build to use tools like Error Prone + NullAway), then there is no impact whatsoever.\n\n=== FAQ\nFor further reference, please consult the following:\n\n* JSpecify https://jspecify.dev/docs/user-guide/[user-guide]\n* Spring https://spring.io/blog/2025/03/10/null-safety-in-spring-apps-with-jspecify-and-null-away[Blog] https://spring.io/blog/2025/11/12/null-safe-applications-with-spring-boot-4[Posts] about null safety\n* https://github.com/uber/NullAway[NullAway] and https://errorprone.info/[ErrorProne]\n"

    "content": "# MCP Spring Transport Migration Guide\n\n## Overview\n\nStarting with **Spring AI 2.0**, the Spring-specific MCP transport implementations\n(`mcp-spring-webflux` and `mcp-spring-webmvc`) are **no longer shipped by the MCP Java SDK**.\nThey have been moved into the Spring AI project itself. This is a breaking change that\nrequires dependency and import updates in every application that directly references\nthese transport classes.\n\n---\n\n## Breaking Changes\n\n### 1. Maven Dependency Group ID Change\n\nThe `mcp-spring-webflux` and `mcp-spring-webmvc` artifacts have moved from the\n`io.modelcontextprotocol.sdk` group to `org.springframework.ai`.\n\n#### Before (MCP Java SDK < 1.0.x & Spring AI < 2.0.x)\n\n```xml\n<dependency>\n    <groupId>io.modelcontextprotocol.sdk</groupId>\n    <artifactId>mcp-spring-webflux</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>io.modelcontextprotocol.sdk</groupId>\n    <artifactId>mcp-spring-webmvc</artifactId>\n</dependency>\n```\n\n#### After (MCP Java SDK ≥ 1.0.x & Spring AI ≥ 2.0.x)\n\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>mcp-spring-webflux</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>mcp-spring-webmvc</artifactId>\n</dependency>\n```\n\n> **Note:** When using the `spring-ai-bom` or the Spring AI starter dependencies\n> (`spring-ai-starter-mcp-server-webflux`, `spring-ai-starter-mcp-server-webmvc`,\n> `spring-ai-starter-mcp-client-webflux`) **no explicit version** is needed — the BOM\n> manages it automatically.\n\n---\n\n### 2. Java Package Relocation\n\nAll transport classes have been moved to `org.springframework.ai` packages.\n\n#### Server Transports\n\n| Class | Old package (MCP SDK) | New package (Spring AI) |\n|---|---|---|\n| `WebFluxSseServerTransportProvider` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webflux.transport` |\n| `WebFluxStreamableServerTransportProvider` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webflux.transport` |\n| `WebFluxStatelessServerTransport` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webflux.transport` |\n| `WebMvcSseServerTransportProvider` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webmvc.transport` |\n| `WebMvcStreamableServerTransportProvider` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webmvc.transport` |\n| `WebMvcStatelessServerTransport` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webmvc.transport` |\n\n#### Client Transports\n\n| Class | Old package (MCP SDK) | New package (Spring AI) |\n|---|---|---|\n| `WebFluxSseClientTransport` | `io.modelcontextprotocol.client.transport` | `org.springframework.ai.mcp.client.webflux.transport` |\n| `WebClientStreamableHttpTransport` | `io.modelcontextprotocol.client.transport` | `org.springframework.ai.mcp.client.webflux.transport` |\n\n#### Example — Update Imports\n\n```java\n// Before\nimport io.modelcontextprotocol.server.transport.WebFluxSseServerTransportProvider;\nimport io.modelcontextprotocol.server.transport.WebMvcSseServerTransportProvider;\nimport io.modelcontextprotocol.client.transport.WebFluxSseClientTransport;\nimport io.modelcontextprotocol.client.transport.WebClientStreamableHttpTransport;\n\n// After\nimport org.springframework.ai.mcp.server.webflux.transport.WebFluxSseServerTransportProvider;\nimport org.springframework.ai.mcp.server.webmvc.transport.WebMvcSseServerTransportProvider;\nimport org.springframework.ai.mcp.client.webflux.transport.WebFluxSseClientTransport;\nimport org.springframework.ai.mcp.client.webflux.transport.WebClientStreamableHttpTransport;\n```\n\n---\n\n### 3. MCP SDK Version Requirement\n\nSpring AI 2.0 requires **MCP Java SDK 1.0.0** (RC1 or later). The SDK version has\nbeen bumped from `0.18.x` to the `1.0.x` release line. Update your BOM or explicit version accordingly.\n\n---\n\n## Spring Boot Auto-configuration Users (No Manual Changes Needed)\n\nIf you rely **exclusively on Spring Boot auto-configuration** via the Spring AI starters,\nyou do **not** need to change any Java code. The auto-configurations have already been\nupdated internally to reference the new packages. Only update your `pom.xml`/`build.gradle`\ndependency coordinates as described in [section 1](#1-maven-dependency-group-id-change).\n\n---\n"

    "content": "# Anthropic Java SDK Integration\n\nThis module integrates the official Anthropic Java SDK with Spring AI, providing access to Claude models through Anthropic's API.\n\n[Anthropic Java SDK GitHub repository](https://github.com/anthropics/anthropic-sdk-java)\n\n## Authentication\n\nConfigure your Anthropic API key either programmatically or via environment variable:\n\n```java\nAnthropicChatOptions options = AnthropicChatOptions.builder()\n    .apiKey(\"<your-api-key>\")\n    .build();\n```\n\nOr using the environment variable (automatically detected):\n\n```bash\nexport ANTHROPIC_API_KEY=<your-api-key>\n```\n\n## Features\n\nThis module supports:\n\n- **Chat Completions** - Synchronous and streaming responses\n- **Tool Calling** - Function calling with automatic tool execution\n- **Streaming Tool Calling** - Tool calls in streaming mode with partial JSON accumulation\n- **Multi-Modal** - Images and PDF documents\n- **Extended Thinking** - Claude's thinking/reasoning feature with full streaming support\n- **Citations** - Document-grounded responses with source attribution\n- **Prompt Caching** - Reduce costs for repeated context with configurable strategies\n- **Structured Output** - JSON schema-constrained responses with effort control\n- **Per-Request HTTP Headers** - Custom headers per API call for tracking, beta features, and routing\n- **Observability** - Micrometer-based metrics and tracing\n\n### Planned Features\n\n- **Amazon Bedrock** - Access Claude through AWS Bedrock\n- **Google Vertex AI** - Access Claude through Google Cloud\n\n## Basic Usage\n\n```java\n// Create chat model with default options\nAnthropicChatModel chatModel = new AnthropicChatModel(\n    AnthropicChatOptions.builder()\n        .model(\"claude-sonnet-4-20250514\")\n        .maxTokens(1024)\n        .build()\n);\n\n// Synchronous call\nChatResponse response = chatModel.call(new Prompt(\"Hello, Claude!\"));\n\n// Streaming call\nFlux<ChatResponse> stream = chatModel.stream(new Prompt(\"Tell me a story\"));\n```\n\n## Tool Calling\n\n```java\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .toolCallbacks(FunctionToolCallback.builder(\"getWeather\", new WeatherService())\n        .description(\"Get the current weather for a location\")\n        .inputType(WeatherRequest.class)\n        .build())\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"What's the weather in Paris?\", options));\n```\n\n## Extended Thinking\n\nEnable Claude's reasoning feature to see step-by-step thinking before the final answer:\n\n```java\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .temperature(1.0) // required when thinking is enabled\n    .maxTokens(16000)\n    .thinkingEnabled(10000L) // budget must be >= 1024 and < maxTokens\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"Solve this step by step...\", options));\n```\n\nThree thinking modes are available via convenience builders:\n- `thinkingEnabled(budgetTokens)` - Enable with a specific token budget\n- `thinkingAdaptive()` - Let Claude decide whether to think\n- `thinkingDisabled()` - Explicitly disable thinking\n\nThinking is fully supported in both synchronous and streaming modes, including signature capture for thinking block verification.\n\n## Citations\n\nAnthropic's Citations API allows Claude to reference specific parts of provided documents when generating responses. Three document types are supported: plain text, PDF, and custom content blocks.\n\n```java\n// Create a citation document\nAnthropicCitationDocument document = AnthropicCitationDocument.builder()\n    .plainText(\"The Eiffel Tower was completed in 1889 in Paris, France. \" +\n               \"It stands 330 meters tall and was designed by Gustave Eiffel.\")\n    .title(\"Eiffel Tower Facts\")\n    .citationsEnabled(true)\n    .build();\n\n// Call the model with the document\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"When was the Eiffel Tower built?\",\n        AnthropicChatOptions.builder()\n            .model(\"claude-sonnet-4-20250514\")\n            .maxTokens(1024)\n            .citationDocuments(document)\n            .build()\n    )\n);\n\n// Access citations from response metadata\nList<Citation> citations = (List<Citation>) response.getMetadata().get(\"citations\");\nfor (Citation citation : citations) {\n    System.out.println(\"Document: \" + citation.getDocumentTitle());\n    System.out.println(\"Cited text: \" + citation.getCitedText());\n}\n```\n\nPDF and custom content block documents are also supported via `pdfFile()`, `pdf()`, and `customContent()` builders.\n\n## Prompt Caching\n\nPrompt caching reduces costs and latency by caching repeated context (system prompts, tool definitions, conversation history) across API calls. Five caching strategies are available:\n\n| Strategy | Description |\n|----------|-------------|\n| `NONE` | No caching (default) |\n| `SYSTEM_ONLY` | Cache system message content |\n| `TOOLS_ONLY` | Cache tool definitions |\n| `SYSTEM_AND_TOOLS` | Cache both system messages and tool definitions |\n| `CONVERSATION_HISTORY` | Cache system messages, tools, and conversation messages |\n\n```java\n// Cache system messages to reduce costs for repeated prompts\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .maxTokens(1024)\n    .cacheOptions(AnthropicCacheOptions.builder()\n        .strategy(AnthropicCacheStrategy.SYSTEM_AND_TOOLS)\n        .build())\n    .build();\n\nChatResponse response = chatModel.call(\n    new Prompt(List.of(\n        new SystemMessage(\"You are an expert assistant with deep domain knowledge...\"),\n        new UserMessage(\"What is the capital of France?\")),\n        options));\n\n// Access cache token usage via native SDK usage\ncom.anthropic.models.messages.Usage sdkUsage =\n    (com.anthropic.models.messages.Usage) response.getMetadata().getUsage().getNativeUsage();\nlong cacheCreation = sdkUsage.cacheCreationInputTokens().orElse(0L);\nlong cacheRead = sdkUsage.cacheReadInputTokens().orElse(0L);\n```\n\nYou can also configure TTL (5 minutes or 1 hour), minimum content length thresholds, and multi-block system caching for static vs. dynamic system message segments:\n\n```java\nvar options = AnthropicCacheOptions.builder()\n    .strategy(AnthropicCacheStrategy.SYSTEM_ONLY)\n    .messageTypeTtl(MessageType.SYSTEM, AnthropicCacheTtl.ONE_HOUR)\n    .messageTypeMinContentLength(MessageType.SYSTEM, 100)\n    .multiBlockSystemCaching(true)\n    .build();\n```\n\n## Structured Output\n\nStructured output constrains Claude to produce responses conforming to a JSON schema. The SDK module also supports Anthropic's effort control for tuning response quality vs speed.\n\n> **Model Requirement:** Structured output and effort control require `claude-sonnet-4-6` or newer. Older models like `claude-sonnet-4-20250514` do not support these features.\n\n### JSON Schema Output\n\n```java\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-6\")\n    .outputSchema(\"\"\"\n        {\n            \"type\": \"object\",\n            \"properties\": {\n                \"name\": {\"type\": \"string\"},\n                \"capital\": {\"type\": \"string\"},\n                \"population\": {\"type\": \"integer\"}\n            },\n            \"required\": [\"name\", \"capital\"],\n            \"additionalProperties\": false\n        }\n        \"\"\")\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"Tell me about France.\", options));\n// Response text will be valid JSON conforming to the schema\n```\n\n### Effort Control\n\nControl how much compute Claude spends on its response. Lower effort means faster, cheaper responses; higher effort means more thorough reasoning.\n\n```java\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-6\")\n    .effort(OutputConfig.Effort.LOW) // LOW, MEDIUM, HIGH, or MAX\n    .build();\n```\n\n### Combined Schema + Effort\n\n```java\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-6\")\n    .outputSchema(\"{\\\"type\\\":\\\"object\\\",\\\"properties\\\":{\\\"answer\\\":{\\\"type\\\":\\\"integer\\\"}},\\\"required\\\":[\\\"answer\\\"],\\\"additionalProperties\\\":false}\")\n    .effort(OutputConfig.Effort.HIGH)\n    .build();\n```\n\n### Direct OutputConfig\n\nFor full control, use the SDK's `OutputConfig` directly:\n\n```java\nimport com.anthropic.models.messages.OutputConfig;\nimport com.anthropic.models.messages.JsonOutputFormat;\nimport com.anthropic.core.JsonValue;\n\nvar outputConfig = OutputConfig.builder()\n    .effort(OutputConfig.Effort.HIGH)\n    .format(JsonOutputFormat.builder()\n        .schema(JsonOutputFormat.Schema.builder()\n            .putAdditionalProperty(\"type\", JsonValue.from(\"object\"))\n            .putAdditionalProperty(\"properties\", JsonValue.from(Map.of(\n                \"name\", Map.of(\"type\", \"string\"))))\n            .putAdditionalProperty(\"additionalProperties\", JsonValue.from(false))\n            .build())\n        .build())\n    .build();\n\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-6\")\n    .outputConfig(outputConfig)\n    .build();\n```\n\n## Per-Request HTTP Headers\n\nAdd custom HTTP headers to individual API calls. Unlike `customHeaders` (which apply to all requests at the client level), `httpHeaders` are set per request.\n\n```java\nvar options = AnthropicChatOptions.builder()\n    .httpHeaders(Map.of(\n        \"X-Request-Id\", \"req-12345\",\n        \"X-Custom-Tracking\", \"my-value\"))\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"Hello\", options));\n```\n\n## Logging\n\nEnable SDK logging by setting the environment variable:\n\n```bash\nexport ANTHROPIC_LOG=debug\n```\n\n## Documentation\n\nFor comprehensive documentation, see:\n- [Spring AI Anthropic Reference Documentation](https://docs.spring.io/spring-ai/reference/api/chat/anthropic-chat.html)\n- [Anthropic API Documentation](https://docs.anthropic.com/)\n- [Anthropic Java SDK Documentation](https://github.com/anthropics/anthropic-sdk-java)\n"

Compliance and governance requirements including data privacy regulations, audit trails, and regulatory compliance frameworks\n\n## Detailed Architecture Guidelines for System-Only Caching\n\n### Microservices Design Patterns\nWhen designing microservices, implement these essential patterns:\n- API Gateway pattern for centralized request routing and cross-cutting concerns\n- Service mesh for inter-service communication, security, and observability\n- Event sourcing for maintaining audit trails and enabling event-driven architectures\n- CQRS (Command Query Responsibility Segregation) for optimal read/write performance\n- Bulkhead pattern to isolate critical resources and prevent cascade failures\n- Circuit breaker pattern with exponential backoff for external service resilience\n- Saga pattern for distributed transaction management across service boundaries\n\n### Data Management Strategies\nImplement robust data management approaches:\n- Database per service pattern to ensure data encapsulation and service autonomy\n- Event-driven data synchronization using message queues and event streams\n- Polyglot persistence choosing optimal data stores for specific use cases\n- Read replicas and sharding strategies for horizontal scaling\n- Data versioning and schema evolution strategies for backward compatibility\n- Distributed caching with Redis or similar for improved performance\n- Data governance frameworks ensuring data quality, lineage, and compliance\n\n### Security Best Practices\nImplement defense-in-depth security measures:\n- OAuth 2.0 and OpenID Connect for authentication and authorization\n- JWT tokens with proper expiration and refresh token mechanisms\n- API rate limiting and throttling to prevent abuse and DDoS attacks\n- Encryption at rest using AES-256 and encryption in transit with TLS 1.3\n- Secret management using HashiCorp Vault or AWS Secrets Manager\n- Network segmentation with VPCs, subnets, and security groups\n- Regular security audits, vulnerability scanning, and penetration testing\n\n### Monitoring and Observability\nEstablish comprehensive observability:\n- Distributed tracing with OpenTelemetry or Jaeger for request flow analysis\n- Centralized logging with ELK stack or similar for log aggregation and analysis\n- Application metrics using Prometheus and Grafana for monitoring and alerting\n- Health checks and readiness probes for service availability monitoring\n- SLA/SLO definitions with error budgets for reliability measurements\n- Alert management with PagerDuty or similar for incident response\n- Performance monitoring with APM tools like New Relic or AppDynamics\n\n### Infrastructure and DevOps\nImplement modern infrastructure practices:\n- Infrastructure as Code using Terraform, CloudFormation, or Pulumi\n- Container orchestration with Kubernetes for scalable deployments\n- GitOps workflows with ArgoCD or Flux for automated deployments\n- Blue-green or canary deployment strategies for zero-downtime releases\n- Automated testing pipelines including unit, integration, and end-to-end tests\n- Code quality gates with SonarQube and static analysis tools\n- Disaster recovery planning with backup strategies and failover procedures\n\nAlways provide concrete examples, architectural diagrams when helpful, code snippets in relevant programming languages,\nand real-world case studies from companies like Netflix, Amazon, Google, Microsoft, and other technology leaders.\nConsider both the technical and business implications of architectural decisions, including time-to-market,\ndevelopment velocity, operational overhead, and long-term maintainability costs.\n\nThis system prompt is specifically designed for testing system-only caching strategies and contains sufficient tokens\nto trigger Anthropic's prompt caching mechanism with Claude Sonnet 4 (1024+ token threshold)."

    "content": "[Google GenAI Chat](https://docs.spring.io/spring-ai/reference/api/chat/google-genai-chat.html)\n\n### Starter\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-google-genai</artifactId>\n</dependency>\n```\n\n### Manual config\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-google-genai</artifactId>\n</dependency>\n```\n\n### Environment variables\n```shell\nexport GOOGLE_GENAI_USE_VERTEXAI=true\nexport GOOGLE_CLOUD_PROJECT='your-project-id'\nexport GOOGLE_CLOUD_LOCATION='your-region'\n```\n\n## Extended Usage Metadata\n\nThe Google GenAI module provides comprehensive usage metadata tracking through the `GoogleGenAiUsage` class, which extends the standard `Usage` interface with additional token tracking capabilities specific to Google GenAI models.\n\n### Features\n\n#### Thinking Tokens\nTrack reasoning tokens for thinking-enabled models like Gemini 2.0 Flash Thinking:\n```java\nChatResponse response = chatModel.call(prompt);\nGoogleGenAiUsage usage = (GoogleGenAiUsage) response.getMetadata().getUsage();\nInteger thoughtsTokens = usage.getThoughtsTokenCount(); // Reasoning tokens\n```\n\n#### Cached Content Tokens\nMonitor tokens from cached context to optimize API costs:\n```java\nInteger cachedTokens = usage.getCachedContentTokenCount(); // Cached context tokens\n```\n\n#### Tool-Use Tokens\nTrack tokens consumed by function calling and tool use:\n```java\nInteger toolUseTokens = usage.getToolUsePromptTokenCount(); // Tool-use tokens\n```\n\n#### Modality Breakdowns\nGet detailed token counts by modality (text, image, audio, video):\n```java\nList<GoogleGenAiModalityTokenCount> promptDetails = usage.getPromptTokensDetails();\nfor (GoogleGenAiModalityTokenCount detail : promptDetails) {\n    System.out.println(detail.getModality() + \": \" + detail.getTokenCount());\n}\n```\n\n#### Traffic Type\nIdentify whether requests use Pay-As-You-Go or Provisioned Throughput:\n```java\nGoogleGenAiTrafficType trafficType = usage.getTrafficType();\n// Returns: ON_DEMAND, PROVISIONED_THROUGHPUT, or UNKNOWN\n```\n\n### Configuration\n\nControl whether to include extended metadata (enabled by default):\n```java\nGoogleGenAiChatOptions options = GoogleGenAiChatOptions.builder()\n    .model(\"gemini-2.0-flash\")\n    .includeExtendedUsageMetadata(true) // Enable extended metadata\n    .build();\n```\n\n### Complete Example\n\n```java\n@Component\npublic class ExtendedUsageExample {\n\n    private final GoogleGenAiChatModel chatModel;\n\n    public void demonstrateExtendedUsage() {\n        Prompt prompt = new Prompt(\"Analyze this complex multi-modal request\");\n        ChatResponse response = chatModel.call(prompt);\n\n        // Cast to GoogleGenAiUsage for extended metadata\n        GoogleGenAiUsage usage = (GoogleGenAiUsage) response.getMetadata().getUsage();\n\n        // Basic token counts (standard Usage interface)\n        System.out.println(\"Prompt tokens: \" + usage.getPromptTokens());\n        System.out.println(\"Completion tokens: \" + usage.getCompletionTokens());\n        System.out.println(\"Total tokens: \" + usage.getTotalTokens());\n\n        // Extended metadata (Google GenAI specific)\n        System.out.println(\"Thinking tokens: \" + usage.getThoughtsTokenCount());\n        System.out.println(\"Cached tokens: \" + usage.getCachedContentTokenCount());\n        System.out.println(\"Tool-use tokens: \" + usage.getToolUsePromptTokenCount());\n\n        // Modality breakdowns\n        if (usage.getPromptTokensDetails() != null) {\n            usage.getPromptTokensDetails().forEach(detail ->\n                System.out.println(\"  \" + detail.getModality() + \": \" + detail.getTokenCount())\n            );\n        }\n\n        // Traffic type\n        System.out.println(\"Traffic type: \" + usage.getTrafficType());\n\n        // Access native SDK object for any additional metadata\n        GenerateContentResponseUsageMetadata nativeUsage =\n            (GenerateContentResponseUsageMetadata) usage.getNativeUsage();\n    }\n}\n```\n\n### Backward Compatibility\n\nThe extended usage metadata maintains full backward compatibility with the standard `Usage` interface. Code using the basic interface continues to work without modification:\n\n```java\n// Works with any Spring AI model\nUsage usage = response.getMetadata().getUsage();\nLong promptTokens = usage.getPromptTokens();\nLong completionTokens = usage.getCompletionTokens();\n```"

Spring              Framework                         Overview\n\n\n            Spring makes it easy to create Java enterprise applications. It provides everything you need to\n            embrace    the  Java   language    in  an  enterprise    environment,      with   support   for  Groovy    and   Kotlin   as\n            alternative languages on the JVM, and with the flexibility to create many kinds of architectures\n            depending     on  an  application’s    needs.  As  of  Spring   Framework      5.1, Spring   requires    JDK  8+  (Java  SE\n            8+) and provides out-of-the-box support for JDK 11 LTS. Java SE 8 update 60 is suggested as the\n            minimum      patch  release   for Java  8, but  it is  generally  recommended       to  use a  recent  patch   release.\n\n            Spring  supports    a wide   range   of application    scenarios.   In  a large  enterprise,   applications    often  exist\n            for a  long  time   and   have   to run   on  a  JDK  and   application    server   whose    upgrade     cycle  is beyond\n            developer    control.   Others   may    run  as  a single   jar with   the  server   embedded,      possibly   in  a cloud\n            environment.      Yet others   may    be standalone     applications    (such   as  batch   or integration    workloads)\n            that do  not  need   a server.\n\n\n            Spring  is open   source.   It  has  a large  and active  community      that  provides   continuous     feedback    based\n            on a  diverse   range  of  real-world   use  cases.  This  has  helped    Spring  to  successfully   evolve   over  a  very\n            long  time.\n\n            1.1.    What          We      Mean          by    \"Spring\"\n\n\n            The  term   \"Spring\"   means    different   things  in  different   contexts.  It can  be  used   to refer  to the  Spring\n            Framework      project   itself,  which  is where    it  all  started.  Over time,  other  Spring   projects   have   been\n            built on  top  of  the Spring    Framework.      Most   often,  when    people   say  \"Spring\",   they  mean    the  entire\n            family  of  projects.  This  reference    documentation       focuses   on  the foundation:     the  Spring   Framework\n            itself.\n\n\n            The  Spring   Framework      is divided   into  modules.    Applications     can  choose   which    modules    they  need.\n            At the heart are the modules of the core container, including a configuration model and a\n            dependency injection mechanism. Beyond that, the Spring Framework provides foundational\n            support    for   different    application     architectures,     including    messaging,      transactional     data   and\n            persistence, and web. It also includes the Servlet-based Spring MVC web framework and, in\n            parallel, the  Spring   WebFlux     reactive   web   framework.\n\n\n            A note about modules: Spring’s framework jars allow for deployment to JDK 9’s module path\n            (\"Jigsaw\"). For use in Jigsaw-enabled applications, the Spring Framework 5 jars come with\n            \"Automatic-Module-Name\" manifest entries which define stable language-level module names\n            (\"spring.core\",   \"spring.context\",     etc.) independent     from    jar artifact  names    (the  jars follow   the  same\n            naming    pattern   with   \"-\" instead   of  \".\",  e.g.  \"spring-core\"  and   \"spring-context\").    Of  course,   Spring’s\n            framework     jars  keep  working    fine  on  the  classpath   on  both  JDK  8  and  9+.\n\n            1.2.    History            of   Spring          and       the      Spring          Framework\n\n\n            Spring came into being in 2003 as a response to the complexity of the early J2EE specifications.\n            While   some    consider   Java   EE  and   its modern-day      successor    Jakarta   EE  to  be  in  competition     with\n            Spring, they are in fact complementary. The Spring programming model does not embrace the\n            Jakarta    EE   platform      specification;    rather,    it  integrates     with    carefully    selected    individual\n\n            specifications   from   the  traditional   EE  umbrella:\n\n\n              • Servlet  API   (JSR 340)\n\n              • WebSocket     API  (JSR  356)\n\n              • Concurrency      Utilities (JSR  236)\n\n              • JSON   Binding    API  (JSR 367)\n\n              • Bean   Validation   (JSR  303)\n\n              • JPA  (JSR  338)\n\n              • JMS   (JSR 914)\n\n              • as well  as  JTA/JCA   setups  for  transaction    coordination,    if necessary.\n\n\n            The  Spring   Framework      also  supports    the Dependency       Injection   (JSR 330)  and   Common      Annotations\n            (JSR 250) specifications, which application developers may choose to use instead of the Spring-\n            specific  mechanisms      provided     by the  Spring   Framework.       Originally,  those   were   based   on  common\n            javax  packages.\n\n            As  of Spring   Framework       6.0, Spring   has  been   upgraded     to  the Jakarta   EE   9 level  (e.g. Servlet   5.0+,\n            JPA  3.0+), based    on  the  jakarta   namespace      instead   of the  traditional   javax   packages.    With   EE  9  as\n            the  minimum      and   EE  10  supported     already,   Spring   is prepared     to provide    out-of-the-box     support\n            for the further evolution of the Jakarta EE APIs. Spring Framework 6.0 is fully compatible with\n            Tomcat   10.1,  Jetty 11  and  Undertow     2.3  as web   servers,   and  also  with  Hibernate    ORM    6.1.\n\n\n            Over   time,  the role  of  Java/Jakarta    EE  in application    development      has  evolved.    In the  early  days   of\n            J2EE  and   Spring,  applications    were   created   to  be deployed     to an  application    server.  Today,   with  the\n            help  of Spring   Boot,   applications    are  created   in a  devops-   and   cloud-friendly     way,  with   the  Servlet\n            container   embedded      and   trivial  to change.   As  of  Spring   Framework      5, a  WebFlux     application    does\n            not  even   use  the  Servlet   API  directly   and   can  run   on  servers   (such   as  Netty)  that  are  not   Servlet\n            containers.\n\n\n            Spring  continues    to  innovate   and   to evolve.  Beyond     the Spring   Framework,      there  are  other   projects,\n            such as Spring Boot, Spring Security, Spring Data, Spring Cloud, Spring Batch, among others. It’s\n            important to remember that each project has its own source code repository, issue tracker, and\n            release  cadence.    See  spring.io/projects    for the  complete    list of Spring   projects.\n\n            1.3.    Design           Philosophy\n\n\n            When you learn about a framework, it’s important to know not only what it does but what\n            principles   it  follows. Here  are  the  guiding   principles   of the  Spring   Framework:\n\n\n              • Provide choice at every level. Spring lets you defer design decisions as late as possible. For\n                example, you can switch persistence providers through configuration without changing your\n                code.  The   same   is true  for  many   other   infrastructure     concerns    and  integration    with  third-party\n                APIs.\n\n              • Accommodate diverse perspectives. Spring embraces flexibility and is not opinionated about\n                how things should be done. It supports a wide range of application needs with different\n                perspectives.\n\n              • Maintain strong backward compatibility. Spring’s evolution has been carefully managed to\n                force  few   breaking    changes    between    versions.   Spring    supports   a  carefully   chosen   range   of  JDK\n                versions and third-party libraries to facilitate maintenance of applications and libraries that\n                depend    on  Spring.\n\n              • Care   about  API   design.  The  Spring   team   puts   a lot of thought   and   time  into  making    APIs  that  are\n                intuitive  and   that  hold  up  across  many    versions   and   many    years.\n\n              • Set high standards for code quality. The Spring Framework puts a strong emphasis on\n                meaningful,     current,   and   accurate    javadoc.   It is one   of very   few  projects   that  can   claim   clean\n                code   structure   with  no  circular   dependencies     between     packages.\n\n            1.4.    Feedback               and       Contributions\n\n\n            For how-to questions or diagnosing or debugging issues, we suggest using Stack Overflow. Click\n            here  for  a list of the  suggested    tags  to use  on  Stack   Overflow.    If  you’re fairly  certain   that there   is a\n            problem    in the  Spring   Framework      or would    like to suggest   a feature,   please  use  the  GitHub    Issues.\n\n            If you have a solution in mind or a suggested fix, you can submit a pull request on Github.\n            However,    please   keep   in mind    that, for  all but  the  most   trivial issues,  we  expect   a  ticket to  be  filed\n            in the issue  tracker,   where   discussions    take  place  and   leave  a record   for  future  reference.\n\n\n            For more    details  see the  guidelines    at the CONTRIBUTING,         top-level  project  page.\n\n            1.5.    Getting           Started\n\n\n            If  you are  just getting   started   with  Spring,   you  may    want   to begin   using   the  Spring   Framework      by\n            creating a Spring Boot-based application. Spring Boot provides a quick (and opinionated) way to\n            create a production-ready Spring-based application. It is based on the Spring Framework, favors\n            convention    over   configuration,    and  is designed    to get  you  up  and  running    as  quickly  as  possible.\n\n\n            You  can  use  start.spring.io    to generate    a basic  project   or follow   one  of  the  \"Getting   Started\"  guides,\n            such as Getting Started Building a RESTful Web Service. As well as being easier to digest, these\n            guides   are  very   task  focused,   and   most   of them    are  based   on   Spring   Boot.  They   also   cover   other\n            projects from the Spring portfolio that you might want to consider when solving a particular\n            problem.\n\n            Chapter                2.    Core           Technologies\n\n\n            This  part  of the  reference    documentation       covers   all  the  technologies   that  are  absolutely   integral   to\n            the Spring   Framework.\n\n\n            Foremost    amongst    these   is  the  Spring Framework’s      Inversion    of Control   (IoC)  container.   A  thorough\n            treatment    of the  Spring   Framework’s      IoC  container    is closely  followed    by  comprehensive       coverage\n            of Spring’s   Aspect-Oriented      Programming        (AOP)   technologies.    The   Spring   Framework       has  its own\n            AOP framework, which is conceptually easy to understand and which successfully addresses the\n            80%   sweet  spot  of AOP   requirements      in Java   enterprise   programming.\n\n\n            Coverage of Spring’s integration with AspectJ (currently the richest — in terms of features — and\n            certainly  most   mature    AOP   implementation       in the  Java  enterprise   space)   is also provided.\n\n\n            AOT processing can be used to optimize your application ahead-of-time. It is typically used for\n            native  image   deployment      using  GraalVM.\n\n            2.1.    The       IoC      Container\n\n\n            This  chapter   covers   Spring’s  Inversion    of Control   (IoC)  container.\n\n\n            2.1.1.   Introduction          to  the   Spring      IoC   Container        and    Beans\n\n            This chapter covers the Spring Framework implementation of the Inversion of Control (IoC)\n            principle. IoC is also known as dependency injection (DI). It is a process whereby objects define\n            their dependencies      (that  is, the other   objects   they  work   with)   only  through    constructor    arguments,\n            arguments to a factory method, or properties that are set on the object instance after it is\n            constructed or returned from a factory method. The container then injects those dependencies\n            when   it creates   the  bean.  This   process   is fundamentally      the  inverse   (hence   the  name,    Inversion    of\n            Control) of the bean itself controlling the instantiation or location of its dependencies by using\n            direct  construction    of classes  or  a mechanism      such   as the  Service  Locator    pattern.\n\n\n            The  org.springframework.beans         and   org.springframework.context         packages     are  the  basis  for  Spring\n            Framework’s       IoC   container.     The   BeanFactory      interface    provides     an   advanced      configuration\n            mechanism capable of managing any type of object. ApplicationContext is a sub-interface of\n            BeanFactory.   It adds:\n\n\n              • Easier   integration   with  Spring’s   AOP   features\n\n              • Message    resource    handling    (for use  in internationalization)\n\n              • Event   publication\n\n              • Application-layer       specific    contexts    such     as  the    WebApplicationContext         for   use   in   web\n                applications.\n\n\n            In short, the BeanFactory provides the configuration framework and basic functionality, and the\n            ApplicationContext       adds    more     enterprise-specific      functionality.     The    ApplicationContext        is  a\n            complete superset of the BeanFactory and is used exclusively in this chapter in descriptions of\n            Spring’s    IoC   container.     For    more     information      on    using    the   BeanFactory      instead    of   the\n\n            ApplicationContext,      see  the  section  covering    the BeanFactory    API.\n\n\n            In Spring, the objects that form the backbone of your application and that are managed by the\n            Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and\n            managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your\n            application.   Beans,   and   the dependencies      among     them,   are  reflected   in the  configuration    metadata\n            used  by  a container.\n\n\n            2.1.2.   Container        Overview\n\n            The  org.springframework.context.ApplicationContext                interface   represents    the  Spring   IoC  container\n            and  is responsible     for instantiating,    configuring,    and   assembling     the  beans.   The  container    gets  its\n            instructions on what objects to instantiate, configure, and assemble by reading configuration\n            metadata.    The  configuration     metadata     is  represented   in  XML,   Java  annotations,    or  Java  code.  It lets\n            you express the objects that compose your application and the rich interdependencies between\n            those  objects.\n\n\n            Several implementations of the ApplicationContext interface are supplied with Spring. In stand-\n            alone applications, it is common to create an instance of ClassPathXmlApplicationContext or\n            FileSystemXmlApplicationContext.           While     XML     has   been     the   traditional    format     for   defining\n            configuration metadata, you can instruct the container to use Java annotations or code as the\n            metadata    format   by  providing    a small   amount    of XML    configuration    to  declaratively   enable    support\n            for these  additional    metadata    formats.\n\n\n            In most application scenarios, explicit user code is not required to instantiate one or more\n            instances   of a  Spring   IoC  container.    For  example,    in a  web   application    scenario,   a simple   eight   (or\n            so) lines  of boilerplate    web   descriptor    XML    in the  web.xml    file of the  application    typically   suffices\n            (see Convenient     ApplicationContext       Instantiation    for Web    Applications).    If you  use  the  Spring   Tools\n            for Eclipse   (an  Eclipse-powered       development      environment),      you   can  easily  create   this  boilerplate\n            configuration    with   a few  mouse    clicks  or keystrokes.\n\n\n            The  following    diagram    shows    a high-level    view   of how   Spring    works.   Your   application    classes  are\n            combined with configuration metadata so that, after the ApplicationContext is created and\n            initialized,  you  have   a fully configured    and   executable    system   or  application.\n\n            Figure  1.  The  Spring IoC container\n\n\n            Configuration      Metadata\n\n            As the preceding diagram shows, the Spring IoC container consumes a form of configuration\n            metadata. This configuration metadata represents how you, as an application developer, tell the\n            Spring  container    to instantiate,   configure,   and   assemble    the  objects  in your   application.\n\n\n            Configuration metadata is traditionally supplied in a simple and intuitive XML format, which is\n            what   most  of  this chapter   uses  to convey    key  concepts    and  features   of the  Spring   IoC container.\n\n\n                              XML-based     metadata     is not  the  only  allowed    form   of configuration     metadata.     The\n                              Spring IoC container itself is totally decoupled from the format in which this\n                             configuration metadata is actually written. These days, many developers choose\n                              Java-based    configuration    for  their  Spring  applications.\n\n\n            For information     about   using   other  forms   of metadata     with  the  Spring   container,   see:\n\n\n              • Annotation-based         configuration:       Spring     2.5   introduced      support      for   annotation-based\n                configuration     metadata.\n\n              • Java-based configuration: Starting with Spring 3.0, many features provided by the Spring\n                JavaConfig project became part of the core Spring Framework. Thus, you can define beans\n                external to your application classes by using Java rather than XML files. To use these new\n                features,   see the  @Configuration,     @Bean,  @Import,  and   @DependsOn   annotations.\n\n            Spring   configuration     consists  of  at least  one   and  typically   more    than  one   bean   definition   that  the\n            container must manage. XML-based configuration metadata configures these beans as <bean/>\n            elements inside a top-level <beans/> element. Java configuration typically uses @Bean-annotated\n            methods    within   a @Configuration     class.\n\n            These   bean   definitions    correspond     to the  actual   objects   that  make   up   your   application.   Typically,\n            you define service layer objects, data access objects (DAOs), presentation objects such as Struts\n            Action instances, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so\n            forth. Typically,   one   does  not  configure    fine-grained     domain    objects   in the  container,    because    it  is\n\n            usually   the responsibility    of  DAOs   and   business    logic  to create  and   load  domain     objects.  However,\n            you  can   use  Spring’s   integration    with  AspectJ    to configure    objects   that  have   been   created   outside\n            the control   of an  IoC  container.   See  Using   AspectJ   to dependency-inject      domain     objects  with  Spring.\n\n\n            The  following   example     shows   the  basic  structure   of XML-based      configuration     metadata:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"...\"    class=\"...\">      ①   ②\n                         <!--   collaborators      and   configuration      for   this   bean  go   here  -->\n                    </bean>\n\n\n                    <bean   id=\"...\"    class=\"...\">\n                         <!--   collaborators      and   configuration      for   this   bean  go   here  -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      go  here   -->\n\n\n              </beans>\n\n\n            ① The    id attribute   is a string  that identifies   the individual    bean   definition.\n\n            ② The    class  attribute   defines   the type  of the  bean   and  uses   the fully  qualified   classname.\n\n            The  value   of the  id attribute   refers   to collaborating    objects.  The   XML    for referring   to  collaborating\n            objects  is not shown    in  this example.    See  Dependencies      for more    information.\n\n\n            Instantiating    a  Container\n\n            The  location   path   or paths   supplied    to an  ApplicationContext       constructor    are  resource    strings  that\n            let  the  container  load  configuration     metadata    from   a variety   of external   resources,    such  as  the local\n            file  system, the  Java  CLASSPATH,   and   so on.\n\n\n            Java\n\n\n              ApplicationContext        context    =  new   ClassPathXmlApplicationContext(\"services.xml\",\n              \"daos.xml\");\n\n\n\n            Kotlin\n\n\n              val   context    =  ClassPathXmlApplicationContext(\"services.xml\",                  \"daos.xml\")\n\n                              After  you  learn   about   Spring’s   IoC  container,    you   may   want   to  know   more    about\n                              Spring’s   Resource     abstraction     (as  described     in  Resources),     which     provides     a\n                             convenient mechanism for reading an InputStream from locations defined in a\n                              URI syntax. In particular, Resource paths are used to construct applications\n                              contexts,  as  described    in Application    Contexts   and   Resource    Paths.\n\n\n            The  following   example     shows   the  service   layer  objects  (services.xml)     configuration     file:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <!--   services    -->\n\n\n                    <bean   id=\"petStore\"\n              class=\"org.springframework.samples.jpetstore.services.PetStoreServiceImpl\">\n                         <property     name=\"accountDao\"        ref=\"accountDao\"/>\n                         <property     name=\"itemDao\"       ref=\"itemDao\"/>\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      for  services     go  here   -->\n\n\n              </beans>\n\n\n\n            The  following   example     shows   the  data  access   objects  daos.xml   file:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"accountDao\"\n                         class=\"org.springframework.samples.jpetstore.dao.jpa.JpaAccountDao\">\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <bean   id=\"itemDao\"\n              class=\"org.springframework.samples.jpetstore.dao.jpa.JpaItemDao\">\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      for  data   access    objects    go  here   -->\n\n\n              </beans>\n\n            In the  preceding    example,     the  service  layer   consists  of  the  PetStoreServiceImpl       class and   two   data\n            access objects of the types JpaAccountDao and JpaItemDao (based on the JPA Object-Relational\n            Mapping    standard).    The  property    name  element    refers  to the  name   of  the JavaBean     property,   and  the\n            ref element refers to the name of another bean definition. This linkage between id and ref\n            elements expresses the dependency between collaborating objects. For details of configuring an\n            object’s  dependencies,     see  Dependencies.\n\n\n\n            Composing    XML-based    Configuration   Metadata\n\n            It can be useful to have bean definitions span multiple XML files. Often, each individual XML\n            configuration    file represents    a logical  layer  or module     in your  architecture.\n\n\n            You can use the application context constructor to load bean definitions from all these XML\n            fragments.    This  constructor    takes  multiple   Resource   locations,   as was   shown    in the  previous    section.\n            Alternatively,   use  one   or more    occurrences     of the  <import/>    element    to load   bean   definitions   from\n            another   file or files. The  following    example    shows    how   to do  so:\n\n\n\n              <beans>\n                    <import    resource=\"services.xml\"/>\n                    <import    resource=\"resources/messageSource.xml\"/>\n                    <import    resource=\"/resources/themeSource.xml\"/>\n\n\n                    <bean   id=\"bean1\"     class=\"...\"/>\n                    <bean   id=\"bean2\"     class=\"...\"/>\n              </beans>\n\n\n\n            In the preceding example, external bean definitions are loaded from three files: services.xml,\n            messageSource.xml,      and  themeSource.xml.      All location   paths   are   relative  to  the  definition   file doing\n            the importing,    so  services.xml    must    be in  the same    directory   or  classpath   location   as  the file doing\n            the importing,     while  messageSource.xml       and  themeSource.xml      must   be  in  a resources    location   below\n            the  location   of the  importing     file.  As  you can  see,  a leading    slash  is ignored.   However,     given   that\n            these  paths   are  relative,  it is better  form   not  to  use  the  slash  at all. The  contents    of the  files being\n            imported,    including   the  top  level  <beans/>   element,    must   be  valid  XML    bean   definitions,   according\n            to the Spring   Schema.\n\n                              It  is  possible,  but  not  recommended,     to reference    files in parent   directories   using   a\n                              relative \"../\" path. Doing so creates a dependency on a file that is outside the\n                              current    application.     In   particular,    this   reference     is  not   recommended          for\n                              classpath: URLs (for example, classpath:../services.xml), where the runtime\n                              resolution process chooses the “nearest” classpath root and then looks into its\n                              parent directory. Classpath configuration changes may lead to the choice of a\n                              different,  incorrect   directory.\n                \n                              You  can  always    use  fully qualified    resource   locations   instead   of  relative  paths:   for\n                              example,        file:C:/config/services.xml             or     classpath:/config/services.xml.\n                              However, be aware that you are coupling your application’s configuration to\n                              specific  absolute   locations.   It  is  generally  preferable  to keep   an indirection    for such\n                              absolute locations — for example, through \"${…}\" placeholders that are resolved\n                              against  JVM   system   properties    at runtime.\n\n\n            The  namespace      itself provides    the  import   directive   feature.  Further    configuration     features   beyond\n            plain bean definitions are available in a selection of XML namespaces provided by Spring — for\n            example,    the context   and   util  namespaces.\n\n\n\n            The Groovy   Bean   Definition  DSL\n\n            As a further example for externalized configuration metadata, bean definitions can also be\n            expressed    in Spring’s   Groovy    Bean   Definition    DSL,  as known     from   the  Grails  framework.     Typically,\n            such  configuration     live in a \".groovy\"    file  with the structure   shown    in  the following    example:\n\n\n\n              beans    {\n                    dataSource(BasicDataSource)           {\n                         driverClassName       =  \"org.hsqldb.jdbcDriver\"\n                         url   =  \"jdbc:hsqldb:mem:grailsDB\"\n                         username     = \"sa\"\n                         password     = \"\"\n                         settings     = [mynew:\"setting\"]\n                    }\n                    sessionFactory(SessionFactory)            {\n                         dataSource     =  dataSource\n                    }\n                    myService(MyService)         {\n                         nestedBean     =  {  AnotherBean     bean   ->\n                               dataSource     =  dataSource\n                         }\n                    }\n              }\n\n\n\n            This  configuration     style  is largely  equivalent     to XML    bean   definitions    and  even   supports    Spring’s\n            XML   configuration     namespaces.      It also  allows   for importing     XML    bean   definition   files through    an\n            importBeans    directive.\n\n            Using   the  Container\n\n            The  ApplicationContext      is the  interface   for an  advanced     factory  capable    of maintaining     a registry   of\n            different beans and their dependencies. By using the method T getBean(String name, Class<T>\n            requiredType),    you  can  retrieve   instances   of  your  beans.\n\n            The  ApplicationContext       lets you   read   bean   definitions   and   access   them,   as  the  following    example\n            shows:\n\n\n            Java\n\n\n              //  create    and   configure    beans\n              ApplicationContext        context    =  new   ClassPathXmlApplicationContext(\"services.xml\",\n              \"daos.xml\");\n\n\n              //  retrieve     configured     instance\n              PetStoreService       service    =  context.getBean(\"petStore\",            PetStoreService.class);\n\n\n              //  use   configured     instance\n              List<String>      userList     = service.getUsernameList();\n\n\n\n            Kotlin\n\n\n              import    org.springframework.beans.factory.getBean\n\n\n              //  create    and   configure    beans\n              val   context    =  ClassPathXmlApplicationContext(\"services.xml\",                  \"daos.xml\")\n\n\n              //  retrieve     configured     instance\n              val   service    =  context.getBean<PetStoreService>(\"petStore\")\n\n\n              //  use   configured     instance\n              var   userList    =  service.getUsernameList()\n\n\n\n            With    Groovy     configuration,      bootstrapping       looks    very    similar.   It  has    a   different    context\n            implementation class which is Groovy-aware (but also understands XML bean definitions). The\n            following   example    shows    Groovy    configuration:\n\n\n            Java\n\n\n              ApplicationContext        context    =  new   GenericGroovyApplicationContext(\"services.groovy\",\n              \"daos.groovy\");\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericGroovyApplicationContext(\"services.groovy\",                    \"daos.groovy\")\n\n\n\n            The  most   flexible  variant   is GenericApplicationContext         in  combination     with   reader   delegates — for\n            example,    with  XmlBeanDefinitionReader        for XML    files,  as  the  following example    shows:\n\n            Java\n\n\n              GenericApplicationContext           context    =  new  GenericApplicationContext();\n              new   XmlBeanDefinitionReader(context).loadBeanDefinitions(\"services.xml\",                           \"daos.xml\");\n              context.refresh();\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericApplicationContext()\n              XmlBeanDefinitionReader(context).loadBeanDefinitions(\"services.xml\",                           \"daos.xml\")\n              context.refresh()\n\n\n\n            You  can  also  use  the GroovyBeanDefinitionReader         for Groovy    files, as the  following   example     shows:\n\n\n            Java\n\n\n              GenericApplicationContext           context    =  new  GenericApplicationContext();\n              new   GroovyBeanDefinitionReader(context).loadBeanDefinitions(\"services.groovy\",\n              \"daos.groovy\");\n              context.refresh();\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericApplicationContext()\n              GroovyBeanDefinitionReader(context).loadBeanDefinitions(\"services.groovy\",\n              \"daos.groovy\")\n              context.refresh()\n\n\n\n            You can mix and match such reader delegates on the same ApplicationContext, reading bean\n            definitions   from   diverse  configuration     sources.\n\n\n            You  can  then  use  getBean   to retrieve   instances    of your  beans.   The  ApplicationContext       interface   has  a\n            few  other   methods    for  retrieving   beans,   but,  ideally, your   application    code   should   never   use  them.\n            Indeed,   your  application    code   should   have   no  calls to  the getBean()    method    at  all  and thus  have   no\n            dependency      on Spring   APIs   at all.  For  example,  Spring’s   integration    with  web   frameworks      provides\n            dependency     injection   for  various   web   framework     components      such   as controllers    and  JSF-managed\n            beans, letting you declare a dependency on a specific bean through metadata (such as an\n            autowiring    annotation).\n\n\n            2.1.3.   Bean     Overview\n\n            A Spring   IoC  container    manages    one   or more    beans.  These   beans   are  created   with   the configuration\n            metadata    that  you  supply   to the  container    (for example,    in the  form   of XML   <bean/>   definitions).\n\n\n            Within   the  container    itself,  these bean   definitions   are  represented     as BeanDefinition     objects,   which\n            contain   (among    other  information)     the  following   metadata:\n\n              • A package-qualified class name: typically, the actual implementation class of the bean being\n\n                defined.\n\n              • Bean behavioral configuration elements, which state how the bean should behave in the\n                container    (scope,  lifecycle  callbacks,   and  so  forth).\n\n              • References     to other  beans   that  are  needed    for the  bean   to do  its work.  These   references    are  also\n                called  collaborators    or  dependencies.\n\n              • Other   configuration     settings   to set  in the  newly    created   object — for    example,    the  size  limit  of\n                the  pool  or the  number     of connections     to use  in a bean   that  manages    a  connection    pool.\n\n\n            This metadata translates to a set of properties that make up each bean definition. The following\n            table describes    these  properties:\n\n\n            Table 1. The  bean  definition\n\n            Property                                                       Explained     in…\n\n            Class                                                          Instantiating   Beans\n\n            Name                                                           Naming    Beans\n\n            Scope                                                          Bean   Scopes\n\n            Constructor     arguments                                      Dependency      Injection\n\n            Properties                                                     Dependency      Injection\n\n            Autowiring     mode                                            Autowiring     Collaborators\n\n            Lazy   initialization   mode                                   Lazy-initialized    Beans\n\n            Initialization   method                                        Initialization   Callbacks\n\n            Destruction     method                                         Destruction    Callbacks\n\n\n            In addition to bean definitions that contain information on how to create a specific bean, the\n            ApplicationContext      implementations       also  permit   the  registration   of existing   objects  that  are  created\n            outside the container (by users). This is done by accessing the ApplicationContext’s BeanFactory\n            through      the     getBeanFactory()        method,       which      returns      the    DefaultListableBeanFactory\n            implementation.          DefaultListableBeanFactory            supports       this     registration       through       the\n            registerSingleton(..)        and    registerBeanDefinition(..)          methods.     However,      typical   applications\n            work   solely  with  beans   defined   through    regular   bean   definition   metadata.\n\n\n                              Bean   metadata    and   manually    supplied    singleton   instances   need   to be  registered    as\n                              early  as possible,   in order   for  the container    to properly    reason    about   them   during\n                              autowiring    and   other  introspection     steps.  While   overriding    existing   metadata    and\n                             existing  singleton    instances    is supported    to  some    degree,   the  registration   of  new\n                              beans at runtime (concurrently with live access to the factory) is not officially\n                              supported    and   may   lead  to  concurrent    access   exceptions,    inconsistent    state  in the\n                              bean  container,    or both.\n\n\n\n            Naming     Beans\n\n            Every   bean   has  one  or  more   identifiers.  These   identifiers   must   be  unique    within   the container    that\n            hosts  the  bean.   A bean   usually   has   only  one   identifier.  However,     if it  requires  more   than   one,  the\n\n            extra  ones  can  be  considered     aliases.\n\n\n            In XML-based      configuration    metadata,    you   use  the  id attribute,  the  name  attribute,  or  both  to specify\n            the  bean   identifiers.  The   id  attribute   lets you   specify  exactly   one   id. Conventionally,     these   names\n            are  alphanumeric      ('myBean',    'someService',    etc.), but  they  can  contain    special  characters    as  well. If\n            you  want    to introduce    other   aliases  for  the  bean,   you  can   also  specify  them    in the  name   attribute,\n            separated    by  a comma     (,), semicolon     (;), or white   space.   As  a historical   note,  in  versions   prior   to\n            Spring   3.1,  the  id  attribute  was defined   as  an xsd:ID   type,  which   constrained     possible   characters.   As\n            of 3.1, it is defined as an xsd:string type. Note that bean id uniqueness is still enforced by the\n            container,   though   no  longer   by  XML   parsers.\n\n\n            You  are  not  required   to supply    a name  or an  id for  a bean.   If  you do not  supply   a  name  or id explicitly,\n            the container    generates    a unique    name    for that  bean.  However,     if you  want   to refer  to  that bean   by\n            name, through the use of the ref element or a Service Locator style lookup, you must provide a\n            name. Motivations for not supplying a name are related to using inner beans and autowiring\n            collaborators.\n\n\n                                                    Bean     Naming        Conventions\n\n               The   convention     is  to  use  the  standard Java  convention     for  instance   field names    when    naming\n               beans. That is, bean names start with a lowercase letter and are camel-cased from there.\n               Examples     of such   names    include   accountManager,    accountService,     userDao,   loginController,     and\n               so  forth.\n\n\n               Naming     beans   consistently    makes    your   configuration     easier  to read   and   understand.     Also,  if\n               you   use  Spring  AOP,   it  helps a lot when   applying    advice   to a set of beans    related  by  name.\n\n\n\n\n                              With component scanning in the classpath, Spring generates bean names for\n                              unnamed     components,      following    the rules  described    earlier:  essentially,   taking  the\n                              simple   class  name    and  turning    its  initial  character  to lower-case.    However,     in the\n                             (unusual)    special  case   when    there  is more    than   one   character    and  both   the  first\n                              and  second   characters    are  upper   case,  the  original  casing   gets preserved.    These   are\n                              the same    rules  as  defined   by  java.beans.Introspector.decapitalize            (which    Spring\n                              uses  here).\n\n\n\n            Aliasing a Bean   outside  the Bean  Definition\n\n            In a bean definition itself, you can supply more than one name for the bean, by using a\n            combination     of up  to  one  name    specified   by  the id  attribute  and   any  number     of other   names    in the\n            name attribute. These names can be equivalent aliases to the same bean and are useful for some\n            situations, such as letting each component in an application refer to a common dependency by\n            using  a bean   name    that is specific  to that  component      itself.\n\n            Specifying all aliases where the bean is actually defined is not always adequate, however. It is\n            sometimes     desirable   to  introduce    an  alias  for a  bean   that  is defined   elsewhere.     This  is commonly\n            the case in large systems where configuration is split amongst each subsystem, with each\n            subsystem     having   its own   set  of object   definitions.   In XML-based      configuration     metadata,    you   can\n            use the  <alias/>   element    to accomplish     this. The  following    example    shows    how   to do  so:\n\n              <alias    name=\"fromName\"       alias=\"toName\"/>\n\n\n\n            In this case, a bean (in the same container) named fromName may also, after the use of this alias\n            definition,  be  referred   to as  toName.\n\n\n            For example,     the configuration     metadata    for  subsystem     A may   refer  to a  DataSource     by the  name    of\n            subsystemA-dataSource.       The  configuration     metadata     for  subsystem     B  may   refer  to a  DataSource     by\n            the name of subsystemB-dataSource. When composing the main application that uses both these\n            subsystems,    the  main   application    refers  to the  DataSource     by  the name    of myApp-dataSource.     To  have\n            all three names refer to the same object, you can add the following alias definitions to the\n            configuration    metadata:\n\n\n\n              <alias    name=\"myApp-dataSource\"          alias=\"subsystemA-dataSource\"/>\n              <alias    name=\"myApp-dataSource\"          alias=\"subsystemB-dataSource\"/>\n\n\n\n            Now   each   component      and  the  main   application    can   refer  to the  dataSource    through    a  name   that  is\n            unique   and   guaranteed      not  to clash   with  any   other   definition   (effectively   creating   a  namespace),\n            yet they  refer  to the  same   bean.\n\n\n                                                           Java-configuration\n\n               If you   use  Javaconfiguration,      the  @Bean  annotation     can   be used   to  provide   aliases.  See   Using\n               the  @Bean  Annotation     for details.\n\n\n\n\n            Instantiating    Beans\n\n            A bean   definition   is essentially   a recipe   for creating   one   or more   objects.   The  container    looks  at the\n            recipe for a named bean when asked and uses the configuration metadata encapsulated by that\n            bean  definition   to  create  (or acquire)   an  actual   object.\n\n\n            If  you use  XML-based      configuration     metadata,    you  specify   the  type  (or  class) of  object  that  is to be\n            instantiated   in  the class  attribute   of the  <bean/>   element.    This  class  attribute   (which,   internally,  is a\n            Class   property      on   a   BeanDefinition      instance)     is  usually    mandatory.       (For   exceptions,     see\n            Instantiation    by  Using   an  Instance   Factory    Method    and   Bean   Definition    Inheritance.)    You   can  use\n            the Class  property    in one   of two  ways:\n\n\n              • Typically, to specify the bean class to be constructed in the case where the container itself\n                directly creates the bean by calling its constructor reflectively, somewhat equivalent to Java\n                code   with  the  new operator.\n\n              • To specify the actual class containing the static factory method that is invoked to create the\n                object,  in the  less common      case  where    the  container    invokes   a static   factory   method    on  a class\n                to create   the  bean.   The  object   type  returned    from    the invocation     of the  static   factory   method\n                may   be  the same    class or  another   class  entirely.\n\n                                                          Nested      class    names\n\n               If you   want   to configure    a  bean   definition   for  a nested   class,  you  may    use  either  the  binary\n               name    or the  source   name    of the  nested   class.\n\n\n               For example, if you have a class called SomeThing in the com.example package, and this\n               SomeThing    class  has  a static   nested   class  called  OtherThing,    they  can   be  separated    by  a dollar\n               sign ($) or a dot (.). So the value of the class attribute in a bean definition would be\n               com.example.SomeThing$OtherThing           or com.example.SomeThing.OtherThing.\n\n\n\n\n\n            Instantiation  with  a Constructor\n\n            When you create a bean by the constructor approach, all normal classes are usable by and\n            compatible    with   Spring.  That   is,  the  class  being developed    does   not  need   to implement     any   specific\n            interfaces or to be coded in a specific fashion. Simply specifying the bean class should suffice.\n            However,     depending     on  what    type  of  IoC  you  use   for that  specific   bean,   you  may    need   a default\n            (empty)   constructor.\n\n\n            The  Spring   IoC  container    can  manage     virtually   any  class  you  want   it to manage.     It  is  not  limited  to\n            managing true JavaBeans. Most Spring users prefer actual JavaBeans with only a default (no-\n            argument) constructor and appropriate setters and getters modeled after the properties in the\n            container.   You   can  also  have   more   exotic  non-bean-style      classes  in  your  container.    If,  for  example,\n            you need to use a legacy connection pool that absolutely does not adhere to the JavaBean\n            specification,   Spring   can  manage    it as well.\n\n\n            With  XML-based      configuration     metadata    you  can   specify  your   bean   class as follows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\"/>\n\n\n              <bean    name=\"anotherExample\"         class=\"examples.ExampleBeanTwo\"/>\n\n\n\n            For details about the mechanism for supplying arguments to the constructor (if required) and\n            setting  object  instance   properties    after the  object  is constructed,    see  Injecting  Dependencies.\n\n\n\n            Instantiation  with  a Static Factory  Method\n\n            When    defining   a bean   that  you  create  with   a static factory   method,    use  the class   attribute  to specify\n            the class  that  contains   the  static   factory   method    and   an  attribute   named    factory-method     to specify\n            the name of the factory method itself. You should be able to call this method (with optional\n            arguments,     as described    later)  and   return   a live  object,  which    subsequently     is treated   as  if it had\n            been  created    through    a constructor.    One   use  for such   a bean   definition   is to call static   factories   in\n            legacy  code.\n\n\n            The  following    bean   definition   specifies   that  the  bean   will  be  created   by  calling   a factory   method.\n            The definition does not specify the type (class) of the returned object, but rather the class\n            containing the factory method. In this example, the createInstance() method must be a static\n            method.   The   following   example     shows   how   to specify   a factory   method:\n\n              <bean    id=\"clientService\"\n                    class=\"examples.ClientService\"\n                    factory-method=\"createInstance\"/>\n\n\n\n            The  following   example     shows   a class  that  would   work    with  the  preceding    bean   definition:\n\n\n            Java\n\n\n              public    class   ClientService      {\n                    private    static   ClientService       clientService      =  new  ClientService();\n                    private    ClientService()       {}\n\n\n                    public   static    ClientService      createInstance()        {\n                         return    clientService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ClientService      private    constructor()      {\n                    companion     object   {\n                         private    val   clientService      =  ClientService()\n                         @JvmStatic\n                         fun   createInstance()       =  clientService\n                    }\n              }\n\n\n\n            For details about the mechanism for supplying (optional) arguments to the factory method and\n            setting  object   instance   properties    after  the  object   is returned    from   the  factory,   see  Dependencies\n            and  Configuration     in Detail.\n\n\n\n            Instantiation  by Using  an  Instance  Factory  Method\n\n            Similar to instantiation through a static factory method, instantiation with an instance factory\n            method    invokes    a non-static   method     of an  existing   bean   from   the  container    to create   a new   bean.\n            To  use  this mechanism,      leave   the  class   attribute  empty    and,   in the  factory-bean     attribute,  specify\n            the name of a bean in the current (or parent or ancestor) container that contains the instance\n            method    that  is  to  be  invoked to  create  the  object.  Set the  name    of the  factory   method    itself with  the\n            factory-method     attribute.  The  following    example    shows    how   to configure    such  a bean:\n\n              <!--   the   factory    bean,   which   contains     a method    called    createInstance()       -->\n              <bean    id=\"serviceLocator\"        class=\"examples.DefaultServiceLocator\">\n                    <!--   inject   any   dependencies      required    by  this   locator    bean   -->\n              </bean>\n\n\n              <!--   the   bean   to  be  created    via  the   factory    bean   -->\n              <bean    id=\"clientService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createClientServiceInstance\"/>\n\n\n\n            The  following   example     shows   the  corresponding      class:\n\n\n            Java\n\n\n              public    class   DefaultServiceLocator         {\n\n\n                    private    static   ClientService       clientService      =  new  ClientServiceImpl();\n\n\n                    public   ClientService       createClientServiceInstance()            {\n                         return    clientService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    DefaultServiceLocator         {\n                    companion     object   {\n                         private    val   clientService      =  ClientServiceImpl()\n                    }\n                    fun  createClientServiceInstance():             ClientService      {\n                         return    clientService\n                    }\n              }\n\n\n\n            One  factory   class can   also hold   more   than  one   factory  method,    as the  following    example    shows:\n\n\n\n              <bean    id=\"serviceLocator\"        class=\"examples.DefaultServiceLocator\">\n                    <!--   inject   any   dependencies      required    by  this   locator    bean   -->\n              </bean>\n\n\n              <bean    id=\"clientService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createClientServiceInstance\"/>\n\n\n              <bean    id=\"accountService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createAccountServiceInstance\"/>\n\n            The  following   example     shows   the  corresponding      class:\n\n\n            Java\n\n\n              public    class   DefaultServiceLocator         {\n\n\n                    private    static   ClientService       clientService      =  new  ClientServiceImpl();\n\n\n                    private    static   AccountService       accountService       = new   AccountServiceImpl();\n\n\n                    public   ClientService       createClientServiceInstance()            {\n                         return    clientService;\n                    }\n\n\n                    public   AccountService       createAccountServiceInstance()             {\n                         return    accountService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    DefaultServiceLocator         {\n                    companion     object   {\n                         private    val   clientService      =  ClientServiceImpl()\n                         private    val   accountService      =  AccountServiceImpl()\n                    }\n\n\n                    fun  createClientServiceInstance():             ClientService      {\n                         return    clientService\n                    }\n\n\n                    fun  createAccountServiceInstance():             AccountService       {\n                         return    accountService\n                    }\n              }\n\n\n\n            This approach shows that the factory bean itself can be managed and configured through\n            dependency     injection   (DI). See  Dependencies      and   Configuration     in Detail.\n\n\n                              In Spring   documentation,       \"factory   bean\"   refers  to a  bean   that is configured     in the\n                              Spring container and that creates objects through an instance or static factory\n                             method. By contrast, FactoryBean (notice the capitalization) refers to a Spring-\n                              specific  FactoryBean    implementation       class.\n\n\n\n            Determining    a Bean’s Runtime    Type\n\n            The runtime type of a specific bean is non-trivial to determine. A specified class in the bean\n            metadata    definition   is just  an  initial class  reference,    potentially   combined      with  a  declared   factory\n            method    or being   a  FactoryBean    class which    may   lead  to  a different   runtime    type  of the  bean,   or not\n\n            being set at all in case of an instance-level factory method (which is resolved via the specified\n            factory-bean name instead). Additionally, AOP proxying may wrap a bean instance with an\n            interface-based     proxy   with   limited  exposure     of the  target   bean’s  actual   type  (just  its implemented\n            interfaces).\n\n            The recommended way to find out about the actual runtime type of a particular bean is a\n            BeanFactory.getType      call  for the  specified   bean   name.   This   takes  all of the  above   cases   into account\n            and  returns   the  type   of object   that a  BeanFactory.getBean       call is going   to return   for  the  same   bean\n            name.\n\n            2.1.4.   Dependencies\n\n            A typical  enterprise    application    does   not  consist  of a  single  object  (or  bean   in the  Spring   parlance).\n            Even   the  simplest   application    has   a few   objects   that  work   together    to present    what   the  end-user\n            sees  as a  coherent    application.    This  next  section   explains    how   you   go  from   defining   a  number     of\n            bean  definitions    that stand   alone  to  a fully realized   application    where   objects   collaborate    to achieve\n            a goal.\n\n\n            Dependency       Injection\n\n            Dependency      injection   (DI) is a process   whereby     objects  define   their  dependencies      (that is, the  other\n            objects  with  which    they  work)   only  through    constructor    arguments,     arguments     to a factory   method,\n            or properties    that  are  set  on  the  object  instance    after  it  is  constructed  or  returned    from   a factory\n            method. The container then injects those dependencies when it creates the bean. This process is\n            fundamentally      the  inverse   (hence   the  name,   Inversion    of  Control)   of the  bean   itself controlling   the\n            instantiation   or  location  of  its  dependencies    on  its own   by  using  direct  construction    of  classes  or the\n            Service  Locator    pattern.\n\n\n            Code   is cleaner   with  the  DI  principle,   and   decoupling    is more    effective  when    objects   are  provided\n            with their dependencies. The object does not look up its dependencies and does not know the\n            location   or class  of  the  dependencies.      As  a result,  your   classes   become    easier   to test, particularly\n            when the dependencies are on interfaces or abstract base classes, which allow for stub or mock\n            implementations       to be used   in unit  tests.\n\n\n            DI  exists   in   two    major    variants:    Constructor-based        dependency       injection    and    Setter-based\n            dependency     injection.\n\n\n\n            Constructor-based    Dependency     Injection\n\n            Constructor-based DI is accomplished by the container invoking a constructor with a number of\n            arguments,      each   representing      a  dependency.       Calling   a   static   factory    method     with    specific\n            arguments to construct the bean is nearly equivalent, and this discussion treats arguments to a\n            constructor    and  to  a static   factory  method     similarly.  The  following    example    shows    a class  that  can\n            only  be dependency-injected        with  constructor     injection:\n\n            Java\n\n\n              public    class   SimpleMovieLister        {\n\n\n                    //  the  SimpleMovieLister        has   a dependency      on  a MovieFinder\n                    private    final   MovieFinder      movieFinder;\n\n\n                    //  a  constructor     so  that   the   Spring   container     can   inject   a  MovieFinder\n                    public   SimpleMovieLister(MovieFinder             movieFinder)      {\n                         this.movieFinder        = movieFinder;\n                    }\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Kotlin\n\n\n              //  a  constructor      so  that   the  Spring    container     can  inject    a MovieFinder\n              class    SimpleMovieLister(private          val   movieFinder:      MovieFinder)      {\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Notice that there is nothing special about this class. It is a POJO that has no dependencies on\n            container   specific  interfaces,   base   classes, or  annotations.\n\n\n            Constructor     Argument      Resolution\n\n            Constructor argument resolution matching occurs by using the argument’s type. If no potential\n            ambiguity exists in the constructor arguments of a bean definition, the order in which the\n            constructor    arguments     are  defined    in a bean   definition    is the order   in  which   those   arguments     are\n            supplied   to the  appropriate     constructor    when   the  bean   is being   instantiated.   Consider    the following\n            class:\n\n\n            Java\n\n\n              package    x.y;\n\n\n              public    class   ThingOne     {\n\n\n                    public   ThingOne(ThingTwo        thingTwo,     ThingThree     thingThree)      {\n                         //  ...\n                    }\n              }\n\n            Kotlin\n\n\n              package    x.y\n\n\n              class    ThingOne(thingTwo:        ThingTwo,    thingThree:      ThingThree)\n\n\n\n            Assuming that the ThingTwo and ThingThree classes are not related by inheritance, no potential\n            ambiguity    exists.  Thus,  the  following    configuration     works    fine, and   you  do  not  need   to  specify  the\n            constructor    argument     indexes   or types   explicitly  in the  <constructor-arg/>      element.\n\n\n\n              <beans>\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\">\n                         <constructor-arg        ref=\"beanTwo\"/>\n                         <constructor-arg        ref=\"beanThree\"/>\n                    </bean>\n\n\n                    <bean   id=\"beanTwo\"      class=\"x.y.ThingTwo\"/>\n\n\n                    <bean   id=\"beanThree\"       class=\"x.y.ThingThree\"/>\n              </beans>\n\n\n\n            When    another   bean   is referenced,    the  type  is known,    and  matching     can  occur   (as was   the case   with\n            the preceding example). When a simple type is used, such as <value>true</value>, Spring cannot\n            determine    the  type  of  the  value,  and  so  cannot   match    by  type  without    help.  Consider    the following\n            class:\n\n\n            Java\n\n\n              package    examples;\n\n\n              public    class   ExampleBean      {\n\n\n                    //  Number    of  years   to  calculate     the  Ultimate     Answer\n                    private    final   int   years;\n\n\n                    //  The  Answer    to  Life,   the   Universe,     and  Everything\n                    private    final   String    ultimateAnswer;\n\n\n                    public   ExampleBean(int       years,    String    ultimateAnswer)       {\n                         this.years     =  years;\n                         this.ultimateAnswer         =  ultimateAnswer;\n                    }\n              }\n\n            Kotlin\n\n\n              package    examples\n\n\n              class    ExampleBean(\n                    private    val  years:    Int,   //  Number    of  years   to  calculate     the  Ultimate     Answer\n                    private    val  ultimateAnswer:       String    //  The   Answer   to  Life,    the  Universe,     and\n              Everything\n              )\n\n\n\n            Constructor   argument    type  matching\n            In the  preceding    scenario,    the  container    can  use  type  matching     with   simple   types  if you   explicitly\n            specify  the  type  of  the  constructor    argument     by  using   the  type  attribute,  as  the  following    example\n            shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       type=\"int\"     value=\"7500000\"/>\n                    <constructor-arg       type=\"java.lang.String\"          value=\"42\"/>\n              </bean>\n\n\n\n            Constructor   argument    index\n            You can use the index attribute to specify explicitly the index of constructor arguments, as the\n            following   example    shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       index=\"0\"     value=\"7500000\"/>\n                    <constructor-arg       index=\"1\"     value=\"42\"/>\n              </bean>\n\n\n\n            In addition to resolving the ambiguity of multiple simple values, specifying an index resolves\n            ambiguity    where    a constructor    has  two  arguments     of  the same    type.\n\n                             The  index   is  0-based.\n\n\n            Constructor   argument    name\n            You can also use the constructor parameter name for value disambiguation, as the following\n            example    shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       name=\"years\"      value=\"7500000\"/>\n                    <constructor-arg       name=\"ultimateAnswer\"         value=\"42\"/>\n              </bean>\n\n\n\n            Keep   in mind    that, to  make   this  work   out  of  the  box,  your   code  must    be  compiled    with   the  debug\n            flag enabled    so that  Spring   can  look   up  the parameter     name    from   the  constructor.    If you  cannot    or\n\n            do not  want   to  compile   your   code   with  the  debug   flag, you   can  use  the  @ConstructorProperties         JDK\n            annotation to explicitly name your constructor arguments. The sample class would then have to\n            look  as follows:\n\n\n            Java\n\n\n              package    examples;\n\n\n              public    class   ExampleBean      {\n\n\n                    //  Fields    omitted\n\n\n                    @ConstructorProperties({\"years\",             \"ultimateAnswer\"})\n                    public   ExampleBean(int       years,    String    ultimateAnswer)       {\n                         this.years     =  years;\n                         this.ultimateAnswer         =  ultimateAnswer;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              package    examples\n\n\n              class    ExampleBean\n              @ConstructorProperties(\"years\",             \"ultimateAnswer\")\n              constructor(val       years:    Int,   val  ultimateAnswer:       String)\n\n\n\n\n            Setter-based  Dependency     Injection\n\n            Setter-based DI is accomplished by the container calling setter methods on your beans after\n            invoking a no-argument constructor or a no-argument static factory method to instantiate your\n            bean.\n\n            The following example shows a class that can only be dependency-injected by using pure setter\n            injection.  This  class  is  conventional   Java.  It is  a  POJO that has  no  dependencies      on  container    specific\n            interfaces,  base   classes,  or annotations.\n\n            Java\n\n\n              public    class   SimpleMovieLister        {\n\n\n                    //  the  SimpleMovieLister        has   a dependency      on  the  MovieFinder\n                    private    MovieFinder     movieFinder;\n\n\n                    //  a  setter   method    so  that   the  Spring    container     can  inject    a  MovieFinder\n                    public   void   setMovieFinder(MovieFinder           movieFinder)      {\n                         this.movieFinder        = movieFinder;\n                    }\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Kotlin\n\n\n              class    SimpleMovieLister       {\n\n\n                    //  a  late-initialized       property    so   that  the   Spring    container    can   inject   a\n              MovieFinder\n                    lateinit    var   movieFinder:      MovieFinder\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            The  ApplicationContext      supports    constructor-based       and  setter-based    DI  for the  beans   it manages.    It\n            also supports setter-based DI after some dependencies have already been injected through the\n            constructor    approach.    You   configure    the  dependencies      in the  form   of  a BeanDefinition,     which    you\n            use  in conjunction     with  PropertyEditor     instances    to convert   properties    from   one  format   to  another.\n            However,    most   Spring   users   do  not  work   with   these  classes  directly   (that is, programmatically)       but\n            rather  with   XML   bean  definitions,   annotated    components      (that  is,  classes annotated    with  @Component,\n            @Controller,   and   so forth),  or @Bean   methods    in  Java-based    @Configuration     classes.  These   sources   are\n            then converted internally into instances of BeanDefinition and used to load an entire Spring IoC\n            container   instance.\n\n                                           Constructor-based              or  setter-based          DI?\n\n               Since   you   can  mix   constructor-based       and  setter-based     DI, it is a  good   rule  of thumb     to use\n               constructors     for  mandatory      dependencies      and  setter   methods    or  configuration     methods     for\n               optional    dependencies.     Note   that  use  of  the  @Autowired      annotation     on  a setter   method    can\n               be  used   to make   the  property    be  a required    dependency;     however,     constructor    injection   with\n               programmatic       validation   of arguments      is  preferable.\n\n               The    Spring    team    generally     advocates     constructor     injection,    as  it  lets  you    implement\n               application components as immutable objects and ensures that required dependencies are\n               not null. Furthermore, constructor-injected components are always returned to the client\n               (calling) code in a fully initialized state. As a side note, a large number of constructor\n               arguments     is a bad   code  smell,  implying    that  the class  likely  has  too many    responsibilities    and\n               should   be  refactored    to better  address    proper   separation    of concerns.\n\n\n               Setter  injection   should   primarily    only  be  used   for optional   dependencies      that  can  be  assigned\n               reasonable default values within the class. Otherwise, not-null checks must be performed\n               everywhere the code uses the dependency. One benefit of setter injection is that setter\n               methods make objects of that class amenable to reconfiguration or re-injection later.\n               Management       through    JMX   MBeans     is  therefore  a compelling    use  case  for  setter  injection.\n\n\n               Use   the  DI  style that  makes     the  most   sense   for a  particular   class.  Sometimes,     when    dealing\n               with   third-party   classes   for which   you   do  not  have  the  source,   the  choice  is made    for you.  For\n               example,    if a third-party    class  does  not  expose   any   setter  methods,    then  constructor     injection\n               may   be  the  only  available   form   of DI.\n\n\n\n\n\n            Dependency    Resolution   Process\n\n            The  container    performs    bean   dependency      resolution   as  follows:\n\n\n              • The   ApplicationContext      is created   and   initialized  with  configuration     metadata     that  describes   all\n                the  beans.  Configuration     metadata     can  be  specified   by XML,   Java   code,  or annotations.\n\n              • For  each  bean,   its dependencies      are expressed     in the  form  of  properties,   constructor    arguments,\n                or arguments to the static-factory method (if you use that instead of a normal constructor).\n                These   dependencies      are  provided    to the bean,   when    the bean   is actually   created.\n\n              • Each   property    or constructor    argument     is an  actual   definition   of the  value  to  set,  or  a reference\n                to another    bean   in the  container.\n\n              • Each   property    or constructor     argument     that  is  a  value  is  converted  from   its  specified format    to\n                the  actual  type  of  that property    or  constructor    argument.     By default,   Spring   can  convert   a value\n                supplied   in  string  format   to all built-in  types,  such  as int,  long, String,   boolean,  and   so forth.\n\n            The  Spring   container    validates   the configuration     of each   bean   as the  container    is  created. However,\n            the bean properties themselves are not set until the bean is actually created. Beans that are\n            singleton-scoped and set to be pre-instantiated (the default) are created when the container is\n            created. Scopes are defined in Bean Scopes. Otherwise, the bean is created only when it is\n            requested. Creation of a bean potentially causes a graph of beans to be created, as the bean’s\n            dependencies      and  its dependencies'      dependencies      (and  so  on)  are  created   and   assigned.    Note  that\n\n            resolution   mismatches      among     those  dependencies      may    show   up  late — that    is,  on  first  creation of\n            the affected   bean.\n\n\n                                                       Circular       dependencies\n\n               If you use predominantly constructor injection, it is possible to create an unresolvable\n               circular   dependency      scenario.\n\n\n               For  example:    Class  A  requires   an  instance   of class  B through    constructor    injection,   and  class  B\n               requires an instance of class A through constructor injection. If you configure beans for\n               classes   A  and  B  to be  injected   into  each   other,  the  Spring   IoC  container    detects   this  circular\n               reference    at runtime,    and  throws    a BeanCurrentlyInCreationException.\n\n\n               One   possible    solution   is to edit  the  source   code   of  some   classes   to be   configured    by  setters\n               rather than constructors. Alternatively, avoid constructor injection and use setter injection\n               only.   In   other    words,    although     it  is  not    recommended,        you    can    configure     circular\n               dependencies      with  setter  injection.\n\n\n               Unlike   the  typical  case  (with   no  circular  dependencies),      a circular   dependency      between    bean\n               A and bean B forces one of the beans to be injected into the other prior to being fully\n               initialized   itself  (a  classic  chicken-and-egg   scenario).\n\n\n\n            You can generally trust Spring to do the right thing. It detects configuration problems, such as\n            references to non-existent beans and circular dependencies, at container load-time. Spring sets\n            properties    and  resolves    dependencies      as late  as  possible,   when    the  bean   is actually   created.   This\n            means    that a  Spring   container    that  has  loaded   correctly   can  later  generate    an  exception    when    you\n            request an object if there is a problem creating that object or one of its dependencies — for\n            example,    the bean   throws    an  exception    as a  result  of a missing   or  invalid   property.   This  potentially\n            delayed visibility of some configuration issues is why ApplicationContext implementations by\n            default pre-instantiate singleton beans. At the cost of some upfront time and memory to create\n            these   beans    before    they    are   actually   needed,     you    discover    configuration      issues   when     the\n            ApplicationContext      is created,  not  later. You   can  still  override  this default   behavior    so that  singleton\n            beans   initialize lazily, rather   than  being   eagerly   pre-instantiated.\n\n\n            If  no circular  dependencies      exist,  when    one  or  more   collaborating     beans   are  being   injected   into  a\n            dependent bean, each collaborating bean is totally configured prior to being injected into the\n            dependent     bean.  This   means    that, if bean   A  has  a dependency      on  bean   B, the  Spring   IoC  container\n            completely    configures    bean    B prior   to invoking    the  setter  method     on  bean   A. In  other   words,   the\n            bean is instantiated (if it is not a pre-instantiated singleton), its dependencies are set, and the\n            relevant lifecycle methods (such as a configured init method or the InitializingBean callback\n            method)    are  invoked.\n\n\n\n            Examples   of Dependency     Injection\n\n            The  following    example    uses  XML-based      configuration     metadata     for setter-based    DI. A  small   part  of\n            a Spring   XML   configuration     file specifies  some   bean   definitions   as  follows:\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <!--   setter   injection     using   the   nested   ref   element    -->\n                    <property     name=\"beanOne\">\n                         <ref   bean=\"anotherExampleBean\"/>\n                    </property>\n\n\n                    <!--   setter   injection     using   the   neater   ref   attribute     -->\n                    <property     name=\"beanTwo\"      ref=\"yetAnotherBean\"/>\n                    <property     name=\"integerProperty\"         value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    private    AnotherBean     beanOne;\n\n\n                    private    YetAnotherBean      beanTwo;\n\n\n                    private    int  i;\n\n\n                    public   void   setBeanOne(AnotherBean          beanOne)    {\n                         this.beanOne      =  beanOne;\n                    }\n\n\n                    public   void   setBeanTwo(YetAnotherBean           beanTwo)    {\n                         this.beanTwo      =  beanTwo;\n                    }\n\n\n                    public   void   setIntegerProperty(int          i)  {\n                         this.i    =  i;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     {\n                    lateinit    var   beanOne:    AnotherBean\n                    lateinit    var   beanTwo:    YetAnotherBean\n                    var  i:  Int   =  0\n              }\n\n\n\n            In the  preceding    example,    setters  are  declared    to match   against   the  properties    specified  in  the XML\n\n            file.  The  following  example    uses  constructor-based       DI:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <!--   constructor     injection     using   the   nested   ref   element    -->\n                    <constructor-arg>\n                         <ref   bean=\"anotherExampleBean\"/>\n                    </constructor-arg>\n\n\n                    <!--   constructor     injection     using   the   neater   ref   attribute     -->\n                    <constructor-arg       ref=\"yetAnotherBean\"/>\n\n\n                    <constructor-arg       type=\"int\"     value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    private    AnotherBean     beanOne;\n\n\n                    private    YetAnotherBean      beanTwo;\n\n\n                    private    int  i;\n\n\n                    public   ExampleBean(\n                         AnotherBean      anotherBean,      YetAnotherBean      yetAnotherBean,       int   i)  {\n                         this.beanOne      =  anotherBean;\n                         this.beanTwo      =  yetAnotherBean;\n                         this.i    =  i;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean(\n                         private    val   beanOne:    AnotherBean,\n                         private    val   beanTwo:    YetAnotherBean,\n                         private    val   i:  Int)\n\n\n\n            The constructor arguments specified in the bean definition are used as arguments to the\n            constructor    of the  ExampleBean.\n\n\n            Now   consider    a variant   of this  example,    where,   instead   of using   a constructor,    Spring   is told  to call\n            a static  factory   method    to return   an  instance   of the  object:\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\"            factory-method=\"createInstance\">\n                    <constructor-arg       ref=\"anotherExampleBean\"/>\n                    <constructor-arg       ref=\"yetAnotherBean\"/>\n                    <constructor-arg       value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    //  a  private    constructor\n                    private    ExampleBean(...)       {\n                         ...\n                    }\n\n\n                    //  a  static   factory    method;    the   arguments     to  this   method   can   be\n                    //  considered     the   dependencies     of   the  bean   that   is  returned,\n                    //  regardless     of  how   those   arguments     are  actually     used.\n                    public   static    ExampleBean      createInstance      (\n                         AnotherBean      anotherBean,      YetAnotherBean      yetAnotherBean,       int   i)  {\n\n\n                         ExampleBean      eb  =  new  ExampleBean      (...);\n                         //  some   other    operations...\n                         return    eb;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     private    constructor()      {\n                    companion     object   {\n                         //  a  static    factory    method;    the  arguments     to  this   method    can  be\n                         //  considered      the  dependencies      of  the   bean  that   is  returned,\n                         //  regardless      of  how  those   arguments     are   actually    used.\n                         @JvmStatic\n                         fun   createInstance(anotherBean:           AnotherBean,      yetAnotherBean:       YetAnotherBean,\n              i:  Int):    ExampleBean     {\n                               val  eb  =  ExampleBean      (...)\n                               //  some   other   operations...\n                               return   eb\n                         }\n                    }\n              }\n\n            Arguments     to  the  static   factory  method     are  supplied    by  <constructor-arg/>      elements,    exactly   the\n            same   as if a constructor    had   actually   been  used.   The  type  of  the class  being   returned    by  the factory\n            method    does   not  have   to be  of  the same    type  as  the  class  that  contains   the  static   factory   method\n            (although, in this example, it is). An instance (non-static) factory method can be used in an\n            essentially   identical   fashion   (aside  from    the  use  of the  factory-bean     attribute   instead   of  the  class\n            attribute),  so we   do not  discuss   those  details  here.\n\n\n            Dependencies       and  Configuration       in Detail\n\n            As mentioned      in the previous    section,  you   can  define  bean   properties    and  constructor    arguments      as\n            references    to other  managed      beans   (collaborators)    or  as values   defined    inline. Spring’s   XML-based\n            configuration     metadata    supports    sub-element      types  within   its <property/>     and   <constructor-arg/>\n            elements    for this purpose.\n\n\n\n            Straight Values  (Primitives,  Strings,  and  so on)\n\n            The  value   attribute   of the  <property/>     element    specifies   a property    or  constructor     argument     as  a\n            human-readable       string  representation.      Spring’s   conversion    service   is used   to convert    these  values\n            from   a String  to  the actual   type  of the  property    or argument.     The  following    example    shows    various\n            values  being   set:\n\n\n\n              <bean    id=\"myDataSource\"       class=\"org.apache.commons.dbcp.BasicDataSource\"                   destroy-\n              method=\"close\">\n                    <!--   results    in  a  setDriverClassName(String)           call   -->\n                    <property     name=\"driverClassName\"         value=\"com.mysql.jdbc.Driver\"/>\n                    <property     name=\"url\"     value=\"jdbc:mysql://localhost:3306/mydb\"/>\n                    <property     name=\"username\"       value=\"root\"/>\n                    <property     name=\"password\"       value=\"misterkaoli\"/>\n              </bean>\n\n\n\n            The  following   example     uses  the  p-namespace      for even   more   succinct   XML   configuration:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                    https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"myDataSource\"        class=\"org.apache.commons.dbcp.BasicDataSource\"\n                         destroy-method=\"close\"\n                         p:driverClassName=\"com.mysql.jdbc.Driver\"\n                         p:url=\"jdbc:mysql://localhost:3306/mydb\"\n                         p:username=\"root\"\n                         p:password=\"misterkaoli\"/>\n\n\n              </beans>\n\n\n\n            The  preceding    XML    is more   succinct.   However,     typos  are  discovered     at runtime    rather   than  design\n\n            time, unless you use an IDE (such as IntelliJ IDEA or the Spring Tools for Eclipse) that supports\n            automatic property completion when you create bean definitions. Such IDE assistance is highly\n            recommended.\n\n\n            You  can  also  configure   a  java.util.Properties      instance,   as  follows:\n\n\n\n              <bean    id=\"mappings\"\n                    class=\"org.springframework.context.support.PropertySourcesPlaceholderConfigurer\">\n\n\n                    <!--   typed   as  a  java.util.Properties         -->\n                    <property     name=\"properties\">\n                         <value>\n                               jdbc.driver.className=com.mysql.jdbc.Driver\n                               jdbc.url=jdbc:mysql://localhost:3306/mydb\n                         </value>\n                    </property>\n              </bean>\n\n\n\n            The Spring container converts the text inside the <value/> element into a java.util.Properties\n            instance   by  using  the  JavaBeans     PropertyEditor     mechanism.      This  is a  nice  shortcut,   and  is one  of  a\n            few  places   where    the  Spring   team   do  favor   the  use  of the  nested    <value/>   element    over   the  value\n            attribute  style.\n\n\n            The  idref  element\n\n            The  idref   element    is simply   an  error-proof    way   to  pass  the  id (a  string  value   -  not a reference)    of\n            another bean in the container to a <constructor-arg/> or <property/> element. The following\n            example    shows   how    to use  it:\n\n\n\n              <bean    id=\"theTargetBean\"        class=\"...\"/>\n\n\n              <bean    id=\"theClientBean\"        class=\"...\">\n                    <property     name=\"targetName\">\n                         <idref    bean=\"theTargetBean\"/>\n                    </property>\n              </bean>\n\n\n\n            The  preceding    bean   definition   snippet   is exactly  equivalent    (at runtime)    to the  following   snippet:\n\n\n\n              <bean    id=\"theTargetBean\"        class=\"...\"     />\n\n\n              <bean    id=\"client\"     class=\"...\">\n                    <property     name=\"targetName\"       value=\"theTargetBean\"/>\n              </bean>\n\n\n\n            The  first form   is preferable    to the  second,   because    using  the  idref   tag lets the  container    validate   at\n            deployment time that the referenced, named bean actually exists. In the second variation, no\n\n            validation   is performed      on  the  value   that is passed    to the  targetName    property    of  the  client  bean.\n            Typos are only discovered (with most likely fatal results) when the client bean is actually\n            instantiated.   If the  client  bean   is a  prototype    bean,  this  typo  and   the  resulting   exception    may   only\n            be discovered     long  after the  container    is  deployed.\n\n\n                              The  local   attribute   on  the  idref   element    is no  longer   supported     in the  4.0  beans\n                              XSD, since it does not provide value over a regular bean reference any more.\n                             Change    your  existing   idref   local   references    to idref   bean  when    upgrading     to the\n                              4.0 schema.\n\n\n            A common      place   (at least  in  versions   earlier   than   Spring   2.0)  where    the  <idref/>   element    brings\n            value is in the configuration of AOP interceptors in a ProxyFactoryBean bean definition. Using\n            <idref/> elements when you specify the interceptor names prevents you from misspelling an\n            interceptor   ID.\n\n\n\n            References   to Other  Beans  (Collaborators)\n\n            The  ref  element    is the  final element    inside   a <constructor-arg/>      or  <property/>    definition   element.\n            Here, you set the value of the specified property of a bean to be a reference to another bean (a\n            collaborator)    managed     by  the  container.    The  referenced     bean   is a  dependency      of the  bean   whose\n            property    is to be  set, and   it is initialized   on  demand     as  needed    before   the  property    is set. (If the\n            collaborator    is a singleton    bean,  it may   already    be  initialized  by  the  container.)    All references    are\n            ultimately   a reference    to another    object.  Scoping   and   validation   depend    on  whether    you   specify  the\n            ID or  name   of the  other   object  through    the bean  or  parent  attribute.\n\n\n            Specifying   the  target  bean   through    the  bean  attribute   of the  <ref/>  tag  is the most   general    form  and\n            allows  creation    of a reference    to any   bean   in the  same   container    or parent    container,   regardless    of\n            whether it is in the same XML file. The value of the bean attribute may be the same as the id\n            attribute   of the  target  bean   or  be  the  same   as  one   of the  values   in the  name   attribute   of the  target\n            bean.  The  following    example    shows    how   to use  a ref  element:\n\n\n\n              <ref   bean=\"someBean\"/>\n\n\n\n            Specifying    the  target  bean   through    the  parent   attribute   creates   a  reference    to a  bean   that  is in  a\n            parent container of the current container. The value of the parent attribute may be the same as\n            either  the id  attribute  of  the target  bean   or  one  of the  values   in the  name  attribute  of  the target  bean.\n            The target bean must be in a parent container of the current one. You should use this bean\n            reference variant mainly when you have a hierarchy of containers and you want to wrap an\n            existing  bean   in  a parent   container    with   a proxy    that  has  the  same   name    as  the  parent   bean.   The\n            following   pair  of listings  shows   how   to use  the  parent   attribute:\n\n\n\n              <!--   in  the   parent   context    -->\n              <bean    id=\"accountService\"        class=\"com.something.SimpleAccountService\">\n                    <!--   insert   dependencies      as  required     here   -->\n              </bean>\n\n              <!--   in  the   child   (descendant)      context    -->\n              <bean    id=\"accountService\"        <!--   bean   name   is  the  same   as  the   parent   bean   -->\n                    class=\"org.springframework.aop.framework.ProxyFactoryBean\">\n                    <property     name=\"target\">\n                         <ref   parent=\"accountService\"/>           <!--   notice   how   we  refer   to  the   parent    bean  -->\n                    </property>\n                    <!--   insert   other    configuration      and  dependencies      as  required     here   -->\n              </bean>\n\n\n\n\n                              The  local  attribute   on  the  ref element    is no  longer   supported    in the  4.0 beans    XSD,\n                             since it does not provide value over a regular bean reference any more. Change\n                              your  existing   ref  local  references    to ref  bean  when    upgrading     to the 4.0  schema.\n\n\n\n            Inner Beans\n\n            A <bean/>   element    inside   the  <property/>    or  <constructor-arg/>      elements    defines   an  inner   bean,   as\n            the following    example    shows:\n\n\n\n              <bean    id=\"outer\"     class=\"...\">\n                    <!--   instead    of  using   a  reference     to  a target    bean,   simply    define    the  target    bean\n              inline    -->\n                    <property     name=\"target\">\n                         <bean    class=\"com.example.Person\">           <!--   this   is  the  inner    bean   -->\n                               <property     name=\"name\"     value=\"Fiona      Apple\"/>\n                               <property     name=\"age\"     value=\"25\"/>\n                         </bean>\n                    </property>\n              </bean>\n\n\n\n            An  inner  bean   definition   does   not  require   a defined   ID  or name.    If specified,  the  container    does  not\n            use such a value as an identifier. The container also ignores the scope flag on creation, because\n            inner  beans   are  always   anonymous       and  are  always    created   with  the  outer  bean.   It  is  not  possible  to\n            access inner beans independently or to inject them into collaborating beans other than into the\n            enclosing   bean.\n\n\n            As a  corner   case,  it  is  possible  to  receive  destruction  callbacks    from   a custom    scope — for    example,\n            for a request-scoped      inner   bean   contained    within   a singleton    bean.  The   creation   of  the inner   bean\n            instance is tied to its containing bean, but destruction callbacks let it participate in the request\n            scope’s  lifecycle.  This  is  not  a common    scenario.   Inner   beans   typically  simply   share   their  containing\n            bean’s  scope.\n\n\n\n            Collections\n\n            The <list/>, <set/>, <map/>, and <props/> elements set the properties and arguments of the Java\n            Collection    types  List,  Set,  Map, and   Properties,    respectively.   The   following    example     shows   how    to\n            use them:\n\n              <bean    id=\"moreComplexObject\"         class=\"example.ComplexObject\">\n                    <!--   results    in  a  setAdminEmails(java.util.Properties)              call   -->\n                    <property     name=\"adminEmails\">\n                         <props>\n                               <prop   key=\"administrator\">administrator@example.org</prop>\n                               <prop   key=\"support\">support@example.org</prop>\n                               <prop   key=\"development\">development@example.org</prop>\n                         </props>\n                    </property>\n                    <!--   results    in  a  setSomeList(java.util.List)           call   -->\n                    <property     name=\"someList\">\n                         <list>\n                               <value>a    list   element    followed    by   a reference</value>\n                               <ref   bean=\"myDataSource\"        />\n                         </list>\n                    </property>\n                    <!--   results    in  a  setSomeMap(java.util.Map)          call   -->\n                    <property     name=\"someMap\">\n                         <map>\n                               <entry   key=\"an    entry\"    value=\"just      some  string\"/>\n                               <entry   key=\"a    ref\"   value-ref=\"myDataSource\"/>\n                         </map>\n                    </property>\n                    <!--   results    in  a  setSomeSet(java.util.Set)          call   -->\n                    <property     name=\"someSet\">\n                         <set>\n                               <value>just     some   string</value>\n                               <ref   bean=\"myDataSource\"        />\n                         </set>\n                    </property>\n              </bean>\n\n\n\n            The  value  of  a map   key  or  value,  or a set  value,  can  also  be any  of  the following    elements:\n\n\n\n              bean   |  ref  |  idref   |  list   |  set  |  map   | props    | value    | null\n\n\n\n            Collection    Merging\n\n            The Spring container also supports merging collections. An application developer can define a\n            parent   <list/>,  <map/>,  <set/>   or  <props/>   element    and  have   child  <list/>,  <map/>,   <set/>  or  <props/>\n            elements inherit and override values from the parent collection. That is, the child collection’s\n            values   are  the  result  of merging     the  elements    of the  parent    and  child   collections,   with  the  child’s\n            collection  elements    overriding    values   specified   in the  parent   collection.\n\n\n            This section on merging discusses the parent-child bean mechanism. Readers unfamiliar with\n            parent   and  child  bean   definitions   may   wish   to read  the  relevant   section   before  continuing.\n\n\n            The  following   example     demonstrates     collection   merging:\n\n              <beans>\n                    <bean   id=\"parent\"      abstract=\"true\"       class=\"example.ComplexObject\">\n                         <property     name=\"adminEmails\">\n                               <props>\n                                    <prop    key=\"administrator\">administrator@example.com</prop>\n                                    <prop    key=\"support\">support@example.com</prop>\n                               </props>\n                         </property>\n                    </bean>\n                    <bean   id=\"child\"     parent=\"parent\">\n                         <property     name=\"adminEmails\">\n                               <!--   the  merge   is   specified    on  the   child   collection     definition     -->\n                               <props   merge=\"true\">\n                                    <prop    key=\"sales\">sales@example.com</prop>\n                                    <prop    key=\"support\">support@example.co.uk</prop>\n                               </props>\n                         </property>\n                    </bean>\n              <beans>\n\n\n\n            Notice  the  use  of the  merge=true    attribute  on  the  <props/>   element    of the  adminEmails    property    of the\n            child bean definition. When the child bean is resolved and instantiated by the container, the\n            resulting   instance   has  an  adminEmails     Properties    collection   that  contains   the  result  of  merging    the\n            child’s  adminEmails    collection   with   the  parent’s   adminEmails    collection.   The   following    listing shows\n            the result:\n\n\n\n              administrator=administrator@example.com\n              sales=sales@example.com\n              support=support@example.co.uk\n\n\n\n            The  child  Properties    collection’s   value   set inherits   all property    elements    from   the  parent   <props/>,\n            and  the  child’s value   for the  support   value  overrides    the  value  in  the parent   collection.\n\n\n            This  merging    behavior     applies   similarly   to the  <list/>,   <map/>,   and  <set/>   collection   types.   In the\n            specific  case  of the  <list/>   element,    the  semantics    associated    with   the List   collection   type  (that  is,\n            the notion    of an  ordered   collection   of  values)  is maintained.     The   parent’s   values   precede    all of the\n            child list’s values. In the case of the Map, Set, and Properties collection types, no ordering exists.\n            Hence,   no  ordering    semantics    are  in effect  for  the collection   types   that  underlie   the  associated    Map,\n            Set, and  Properties    implementation       types  that  the container    uses  internally.\n\n\n            Limitations     of Collection    Merging\n\n            You  cannot   merge    different   collection  types   (such  as  a Map and   a List).  If  you do  attempt   to do  so, an\n            appropriate    Exception    is  thrown.  The  merge   attribute  must   be  specified   on  the lower,   inherited,   child\n            definition.  Specifying    the  merge  attribute   on a  parent   collection  definition    is  redundant   and   does  not\n            result in  the desired   merging.\n\n            Strongly-typed      collection\n\n            Thanks to Java’s support for generic types, you can use strongly typed collections. That is, it is\n            possible   to declare   a Collection    type  such   that  it  can  only contain   (for example)     String   elements.   If\n            you use Spring to dependency-inject a strongly-typed Collection into a bean, you can take\n            advantage of Spring’s type-conversion support such that the elements of your strongly-typed\n            Collection    instances   are  converted     to the  appropriate     type  prior  to  being   added   to  the Collection.\n            The  following   Java   class and   bean  definition   show    how   to do  so:\n\n\n            Java\n\n\n              public    class   SomeClass     {\n\n\n                    private    Map<String,     Float>    accounts;\n\n\n                    public   void   setAccounts(Map<String,          Float>    accounts)     {\n                         this.accounts       = accounts;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    SomeClass    {\n                    lateinit    var   accounts:    Map<String,      Float>\n              }\n\n\n\n\n              <beans>\n                    <bean   id=\"something\"       class=\"x.y.SomeClass\">\n                         <property     name=\"accounts\">\n                               <map>\n                                    <entry    key=\"one\"     value=\"9.99\"/>\n                                    <entry    key=\"two\"     value=\"2.75\"/>\n                                    <entry    key=\"six\"     value=\"3.99\"/>\n                               </map>\n                         </property>\n                    </bean>\n              </beans>\n\n\n\n            When     the   accounts    property     of  the   something     bean    is  prepared     for   injection,   the   generics\n            information about the element type of the strongly-typed Map<String, Float> is available by\n            reflection.  Thus,   Spring’s   type  conversion     infrastructure     recognizes    the  various    value  elements     as\n            being  of  type  Float,  and   the  string  values   (9.99,  2.75,  and  3.99)   are  converted    into  an  actual   Float\n            type.\n\n\n\n            Null and  Empty   String Values\n\n            Spring   treats  empty    arguments     for  properties    and   the  like  as empty    Strings.   The   following    XML-\n            based   configuration    metadata     snippet   sets the  email  property    to the empty    String   value  (\"\").\n\n              <bean    class=\"ExampleBean\">\n                    <property     name=\"email\"     value=\"\"/>\n              </bean>\n\n\n\n            The  preceding    example    is equivalent    to the  following    Java  code:\n\n\n            Java\n\n\n              exampleBean.setEmail(\"\");\n\n\n\n            Kotlin\n\n\n              exampleBean.email        =  \"\"\n\n\n\n            The  <null/>   element    handles   null  values.  The   following   listing  shows   an  example:\n\n\n\n              <bean    class=\"ExampleBean\">\n                    <property     name=\"email\">\n                         <null/>\n                    </property>\n              </bean>\n\n\n\n            The  preceding    configuration     is  equivalent   to the following    Java  code:\n\n\n            Java\n\n\n              exampleBean.setEmail(null);\n\n\n\n            Kotlin\n\n\n              exampleBean.email        =  null\n\n\n\n\n            XML  Shortcut   with  the p-namespace\n\n            The  p-namespace      lets you   use  the bean  element’s    attributes   (instead   of nested   <property/>    elements)\n            to describe   your   property   values   collaborating    beans,   or both.\n\n\n            Spring supports extensible configuration formats with namespaces, which are based on an XML\n            Schema    definition.   The   beans  configuration     format    discussed    in this  chapter   is defined    in an  XML\n            Schema    document.     However,     the  p-namespace       is not  defined   in  an  XSD   file and  exists  only   in the\n            core  of Spring.\n\n\n            The following example shows two XML snippets (the first uses standard XML format and the\n            second   uses  the  p-namespace)      that resolve   to the  same   result:\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   name=\"classic\"       class=\"com.example.ExampleBean\">\n                         <property     name=\"email\"      value=\"someone@somewhere.com\"/>\n                    </bean>\n\n\n                    <bean   name=\"p-namespace\"        class=\"com.example.ExampleBean\"\n                         p:email=\"someone@somewhere.com\"/>\n              </beans>\n\n\n\n            The  example     shows    an  attribute   in the  p-namespace       called  email  in  the  bean   definition.   This  tells\n            Spring   to include   a property    declaration.    As  previously    mentioned,     the p-namespace       does  not  have\n            a schema    definition,   so you  can  set  the name    of the  attribute   to the property    name.\n\n\n            This  next  example    includes   two   more   bean   definitions   that  both  have   a reference    to another   bean:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   name=\"john-classic\"         class=\"com.example.Person\">\n                         <property     name=\"name\"      value=\"John     Doe\"/>\n                         <property     name=\"spouse\"      ref=\"jane\"/>\n                    </bean>\n\n\n                    <bean   name=\"john-modern\"\n                         class=\"com.example.Person\"\n                         p:name=\"John      Doe\"\n                         p:spouse-ref=\"jane\"/>\n\n\n                    <bean   name=\"jane\"      class=\"com.example.Person\">\n                         <property     name=\"name\"      value=\"Jane     Doe\"/>\n                    </bean>\n              </beans>\n\n\n\n            This example includes not only a property value using the p-namespace but also uses a special\n            format    to   declare    property     references.     Whereas       the   first  bean    definition     uses   <property\n            name=\"spouse\" ref=\"jane\"/> to create a reference from bean john to bean jane, the second bean\n            definition   uses  p:spouse-ref=\"jane\"       as an  attribute   to do  the exact   same   thing.  In this  case,  spouse  is\n            the property name, whereas the -ref part indicates that this is not a straight value but rather a\n            reference   to another    bean.\n\n                              The  p-namespace       is  not  as  flexible  as  the  standard  XML    format.   For  example,    the\n                              format   for  declaring    property    references    clashes   with   properties   that  end   in  Ref,\n                             whereas    the  standard    XML   format    does  not.  We   recommend       that  you  choose   your\n                              approach     carefully    and    communicate        this  to   your   team    members       to  avoid\n                              producing    XML    documents     that  use  all  three approaches     at the  same   time.\n\n\n\n            XML  Shortcut   with  the c-namespace\n\n            Similar to the XML Shortcut with the p-namespace, the c-namespace, introduced in Spring 3.1,\n            allows  inlined   attributes   for configuring     the constructor    arguments      rather  then   nested   constructor-\n            arg elements.\n\n\n            The  following    example    uses   the  c: namespace      to do  the  same    thing  as the  from   Constructor-based\n            Dependency      Injection:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:c=\"http://www.springframework.org/schema/c\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"beanTwo\"      class=\"x.y.ThingTwo\"/>\n                    <bean   id=\"beanThree\"       class=\"x.y.ThingThree\"/>\n\n\n                    <!--   traditional     declaration      with   optional    argument    names    -->\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\">\n                         <constructor-arg        name=\"thingTwo\"       ref=\"beanTwo\"/>\n                         <constructor-arg        name=\"thingThree\"       ref=\"beanThree\"/>\n                         <constructor-arg        name=\"email\"      value=\"something@somewhere.com\"/>\n                    </bean>\n\n\n                    <!--   c-namespace     declaration      with   argument    names   -->\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\"         c:thingTwo-ref=\"beanTwo\"\n                         c:thingThree-ref=\"beanThree\"            c:email=\"something@somewhere.com\"/>\n\n\n              </beans>\n\n\n\n            The  c: namespace      uses   the same    conventions     as the  p: one   (a trailing  -ref  for  bean   references)    for\n            setting  the  constructor    arguments     by  their  names.   Similarly,   it needs   to be  declared   in  the  XML   file\n            even  though    it  is  not  defined  in  an  XSD  schema  (it  exists  inside  the  Spring core).\n\n            For the  rare  cases   where   the  constructor    argument     names    are  not  available   (usually   if  the  bytecode\n            was   compiled    without    debugging     information),     you   can  use  fallback   to  the  argument     indexes,    as\n            follows:\n\n              <!--   c-namespace      index   declaration     -->\n              <bean    id=\"beanOne\"     class=\"x.y.ThingOne\"         c:_0-ref=\"beanTwo\"        c:_1-ref=\"beanThree\"\n                    c:_2=\"something@somewhere.com\"/>\n\n\n\n\n                              Due  to  the XML    grammar,     the  index   notation    requires   the  presence    of the  leading\n                              _, as XML attribute names cannot start with a number (even though some IDEs\n                             allow it). A corresponding index notation is also available for <constructor-arg>\n                              elements but not commonly used since the plain order of declaration is usually\n                              sufficient  there.\n\n\n            In practice, the constructor resolution mechanism is quite efficient in matching arguments, so\n            unless  you   really need   to, we  recommend       using   the name    notation   throughout     your   configuration.\n\n\n\n            Compound     Property  Names\n\n            You can use compound or nested property names when you set bean properties, as long as all\n            components      of the  path   except   the  final property    name    are  not   null. Consider    the  following    bean\n            definition:\n\n\n\n              <bean    id=\"something\"      class=\"things.ThingOne\">\n                    <property     name=\"fred.bob.sammy\"         value=\"123\"     />\n              </bean>\n\n\n\n            The  something    bean   has  a fred  property,    which   has  a  bob property,    which   has  a  sammy  property,   and\n            that final  sammy  property    is being  set  to a value   of 123. In  order  for  this to work,   the  fred  property    of\n            something   and   the  bob property    of  fred  must   not  be  null  after  the bean   is constructed.    Otherwise,     a\n            NullPointerException      is thrown.\n\n\n            Using   depends-on\n\n            If  a  bean is  a  dependency    of another    bean,  that  usually   means    that  one  bean   is set as  a property    of\n            another. Typically you accomplish this with the <ref/> element in XML-based configuration\n            metadata.    However,     sometimes     dependencies      between    beans   are  less  direct. An   example    is when    a\n            static initializer in a class needs to be triggered, such as for database driver registration. The\n            depends-on    attribute   can  explicitly  force   one  or  more   beans    to be  initialized  before   the  bean   using\n            this element is initialized. The following example uses the depends-on attribute to express a\n            dependency     on  a single   bean:\n\n\n\n              <bean    id=\"beanOne\"     class=\"ExampleBean\"         depends-on=\"manager\"/>\n              <bean    id=\"manager\"     class=\"ManagerBean\"         />\n\n\n\n            To express    a dependency      on  multiple   beans,   supply   a list  of  bean  names  as  the value   of the  depends-\n            on attribute   (commas,    whitespace,     and  semicolons     are valid  delimiters):\n\n              <bean    id=\"beanOne\"     class=\"ExampleBean\"         depends-on=\"manager,accountDao\">\n                    <property     name=\"manager\"      ref=\"manager\"      />\n              </bean>\n\n\n              <bean    id=\"manager\"     class=\"ManagerBean\"         />\n              <bean    id=\"accountDao\"       class=\"x.y.jdbc.JdbcAccountDao\"             />\n\n\n\n\n                              The  depends-on    attribute  can   specify  both   an initialization-time     dependency      and,  in\n                              the case of singleton beans only, a corresponding destruction-time dependency.\n                             Dependent beans that define a depends-on relationship with a given bean are\n                              destroyed    first,  prior  to  the  given  bean itself being   destroyed.   Thus,   depends-on    can\n                              also control   shutdown     order.\n\n\n\n            Lazy-initialized     Beans\n\n            By  default,  ApplicationContext      implementations       eagerly   create   and  configure    all singleton   beans    as\n            part  of the  initialization  process.   Generally,    this pre-instantiation     is desirable,   because   errors   in the\n            configuration or surrounding environment are discovered immediately, as opposed to hours or\n            even days later. When this behavior is not desirable, you can prevent pre-instantiation of a\n            singleton   bean   by  marking    the  bean   definition   as being   lazy-initialized.   A  lazy-initialized   bean   tells\n            the IoC  container    to create  a bean   instance   when    it is  first  requested, rather   than  at startup.\n\n\n            In XML, this behavior is controlled by the lazy-init attribute on the <bean/> element, as the\n            following   example    shows:\n\n\n\n              <bean    id=\"lazy\"    class=\"com.something.ExpensiveToCreateBean\"                  lazy-init=\"true\"/>\n              <bean    name=\"not.lazy\"       class=\"com.something.AnotherBean\"/>\n\n\n\n            When the preceding configuration is consumed by an ApplicationContext, the lazy bean is not\n            eagerly   pre-instantiated     when    the  ApplicationContext      starts,  whereas    the  not.lazy    bean   is eagerly\n            pre-instantiated.\n\n\n            However, when a lazy-initialized bean is a dependency of a singleton bean that is not lazy-\n            initialized, the ApplicationContext creates the lazy-initialized bean at startup, because it must\n            satisfy the singleton’s dependencies. The lazy-initialized bean is injected into a singleton bean\n            elsewhere    that  is  not  lazy-initialized.\n\n            You can also control lazy-initialization at the container level by using the default-lazy-init\n            attribute  on  the  <beans/>   element,   as  the following    example    shows:\n\n\n\n              <beans    default-lazy-init=\"true\">\n                    <!--   no  beans   will   be  pre-instantiated...         -->\n              </beans>\n\n            Autowiring     Collaborators\n\n            The  Spring   container    can   autowire    relationships     between    collaborating     beans.   You  can   let Spring\n            resolve   collaborators    (other   beans)   automatically     for  your   bean   by  inspecting    the  contents    of the\n            ApplicationContext.      Autowiring    has  the  following    advantages:\n\n              • Autowiring can significantly reduce the need to specify properties or constructor arguments.\n                (Other mechanisms such as a bean template discussed elsewhere in this chapter are also\n                valuable    in this regard.)\n\n              • Autowiring     can  update    a configuration    as  your  objects   evolve.  For  example,    if you  need   to add   a\n                dependency      to  a class,  that dependency       can  be  satisfied  automatically     without    you   needing    to\n                modify the configuration. Thus autowiring can be especially useful during development,\n                without    negating    the option   of  switching    to explicit  wiring    when    the code   base   becomes     more\n                stable.\n\n\n            When using XML-based configuration metadata (see Dependency Injection), you can specify the\n            autowire mode for a bean definition with the autowire attribute of the <bean/> element. The\n            autowiring functionality has four modes. You specify autowiring per bean and can thus choose\n            which   ones  to  autowire.   The   following   table  describes   the  four  autowiring     modes:\n\n\n            Table 2. Autowiring    modes\n\n            Mode                     Explanation\n            no                       (Default)   No  autowiring.    Bean   references    must   be  defined   by  ref elements.\n                                     Changing     the default   setting  is not  recommended       for  larger  deployments,\n                                     because    specifying   collaborators     explicitly  gives  greater   control  and   clarity. To\n                                     some    extent,  it  documents    the structure   of  a system.\n            byName                   Autowiring     by  property    name.   Spring   looks  for a  bean  with   the same    name   as\n                                     the  property    that needs   to be  autowired.    For  example,    if a bean   definition   is\n                                     set to  autowire    by name    and  it contains   a master   property    (that is, it  has  a\n                                     setMaster(..)     method),    Spring   looks  for a  bean  definition   named     master  and\n                                     uses  it to set the  property.\n            byType                   Lets  a property    be  autowired    if exactly  one   bean  of  the property    type  exists  in\n                                     the  container.   If more   than   one  exists, a  fatal exception    is  thrown,  which\n                                     indicates   that  you  may   not  use  byType   autowiring    for that  bean.   If  there are no\n                                     matching     beans,  nothing    happens    (the  property   is not  set).\n            constructor              Analogous     to byType   but  applies  to constructor    arguments.     If there  is not\n                                     exactly   one  bean   of the  constructor    argument     type  in the  container,   a fatal\n                                     error   is  raised.\n\n\n            With byType or constructor autowiring mode, you can wire arrays and typed collections. In such\n            cases,  all autowire    candidates     within   the  container    that  match    the  expected    type  are  provided     to\n            satisfy  the  dependency.     You   can  autowire     strongly-typed     Map  instances   if the  expected    key   type  is\n            String. An autowired Map instance’s values consist of all bean instances that match the expected\n            type, and   the Map  instance’s   keys  contain   the  corresponding      bean   names.\n\n            Limitations  and  Disadvantages    of Autowiring\n\n            Autowiring works best when it is used consistently across a project. If autowiring is not used in\n            general,  it might   be confusing    to developers     to use  it  to  wire  only  one  or  two  bean definitions.\n\n\n            Consider   the  limitations   and   disadvantages     of autowiring:\n\n              • Explicit  dependencies      in  property   and  constructor-arg      settings  always    override   autowiring.     You\n                cannot    autowire    simple   properties    such  as  primitives,   Strings,   and   Classes   (and  arrays   of such\n                simple   properties).   This  limitation   is by-design.\n\n              • Autowiring     is less  exact  than   explicit  wiring.   Although,    as  noted   in  the  earlier  table,  Spring   is\n                careful to avoid guessing in case of ambiguity that might have unexpected results. The\n                relationships    between    your   Spring-managed       objects   are  no longer   documented      explicitly.\n\n              • Wiring information may not be available to tools that may generate documentation from a\n                Spring   container.\n\n              • Multiple bean definitions within the container may match the type specified by the setter\n                method    or  constructor    argument     to be  autowired.    For  arrays,  collections,   or Map  instances,   this is\n                not  necessarily    a problem.    However,     for dependencies      that  expect   a single  value,  this  ambiguity\n                is not  arbitrarily  resolved.   If no  unique   bean   definition   is available,   an  exception   is thrown.\n\n\n            In the  latter scenario,   you  have   several   options:\n\n              • Abandon     autowiring     in favor  of explicit  wiring.\n\n              • Avoid   autowiring     for  a bean   definition    by  setting  its autowire-candidate       attributes   to false,   as\n                described    in the  next  section.\n\n              • Designate    a single  bean   definition   as the  primary    candidate    by  setting  the  primary  attribute   of its\n                <bean/>   element    to true.\n\n              • Implement the more fine-grained control available with annotation-based configuration, as\n                described    in Annotation-based       Container    Configuration.\n\n\n\n            Excluding   a  Bean from  Autowiring\n\n            On a per-bean basis, you can exclude a bean from autowiring. In Spring’s XML format, set the\n            autowire-candidate      attribute   of the  <bean/>  element    to false.  The   container    makes   that  specific  bean\n            definition   unavailable     to the  autowiring     infrastructure     (including   annotation     style  configurations\n            such  as @Autowired).\n\n\n                              The  autowire-candidate       attribute   is designed    to only  affect  type-based     autowiring.\n                              It does not affect explicit references by name, which get resolved even if the\n                             specified bean is not marked as an autowire candidate. As a consequence,\n                              autowiring    by  name    nevertheless    injects  a bean   if  the  name  matches.\n\n\n            You can also limit autowire candidates based on pattern-matching against bean names. The top-\n            level <beans/> element accepts one or more patterns within its default-autowire-candidates\n            attribute. For example, to limit autowire candidate status to any bean whose name ends with\n            Repository,   provide    a value   of *Repository.    To  provide    multiple   patterns,   define   them   in  a comma-\n            separated    list.  An  explicit  value of true  or  false  for  a bean   definition’s   autowire-candidate      attribute\n\n            always   takes  precedence.     For  such  beans,   the pattern   matching     rules  do  not apply.\n\n\n            These techniques are useful for beans that you never want to be injected into other beans by\n            autowiring. It does not mean that an excluded bean cannot itself be configured by using\n            autowiring.    Rather,   the bean   itself is not a  candidate    for autowiring    other   beans.\n\n\n            Method    Injection\n\n            In most   application    scenarios,    most   beans   in the  container    are   singletons.   When    a  singleton   bean\n            needs   to collaborate    with  another    singleton   bean   or a  non-singleton     bean   needs   to collaborate    with\n            another non-singleton bean, you typically handle the dependency by defining one bean as a\n            property    of the  other.  A  problem     arises  when    the  bean   lifecycles   are  different.  Suppose     singleton\n            bean   A  needs   to use   non-singleton     (prototype)    bean   B, perhaps     on  each   method    invocation     on  A.\n            The  container    creates   the singleton    bean   A only  once,   and  thus   only  gets  one  opportunity     to set the\n            properties.   The   container    cannot   provide    bean   A  with  a  new   instance   of  bean   B every   time   one  is\n            needed.\n\n            A solution   is to  forego   some   inversion    of control.   You  can   make   bean   A  aware    of the  container    by\n            implementing the ApplicationContextAware interface, and by making a getBean(\"B\") call to the\n            container ask for (a typically new) bean B instance every time bean A needs it. The following\n            example    shows   this  approach:\n\n            Java\n\n\n              //  a  class   that   uses   a  stateful    Command-style       class   to  perform    some   processing\n              package    fiona.apple;\n\n\n              //  Spring-API      imports\n              import    org.springframework.beans.BeansException;\n              import    org.springframework.context.ApplicationContext;\n              import    org.springframework.context.ApplicationContextAware;\n\n\n              public    class   CommandManager       implements     ApplicationContextAware          {\n\n\n                    private    ApplicationContext        applicationContext;\n\n\n                    public   Object    process(Map      commandState)      {\n                         //  grab   a  new   instance    of  the   appropriate     Command\n                         Command    command    =  createCommand();\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    protected     Command    createCommand()       {\n                         //  notice    the   Spring   API   dependency!\n                         return    this.applicationContext.getBean(\"command\",                 Command.class);\n                    }\n\n\n                    public   void   setApplicationContext(\n                               ApplicationContext        applicationContext)        throws    BeansException       {\n                         this.applicationContext          =  applicationContext;\n                    }\n              }\n\n            Kotlin\n\n\n              //  a  class   that   uses   a  stateful    Command-style       class   to  perform    some   processing\n              package    fiona.apple\n\n\n              //  Spring-API      imports\n              import    org.springframework.context.ApplicationContext\n              import    org.springframework.context.ApplicationContextAware\n\n\n              class    CommandManager      :  ApplicationContextAware          {\n\n\n                    private    lateinit    var   applicationContext:        ApplicationContext\n\n\n                    fun  process(commandState:          Map<*,   *>):   Any   {\n                         //  grab   a  new   instance    of  the   appropriate     Command\n                         val   command    =  createCommand()\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    //  notice    the  Spring    API  dependency!\n                    protected     fun  createCommand()       =\n                               applicationContext.getBean(\"command\",               Command::class.java)\n\n\n                    override    fun   setApplicationContext(applicationContext:                ApplicationContext)         {\n                         this.applicationContext          =  applicationContext\n                    }\n              }\n\n\n\n            The preceding is not desirable, because the business code is aware of and coupled to the Spring\n            Framework.      Method    Injection,   a somewhat      advanced     feature   of  the  Spring   IoC  container,   lets  you\n            handle   this use  case  cleanly.\n\n\n\n               You   can  read  more   about   the  motivation    for  Method    Injection   in this blog  entry.\n\n\n\n\n\n            Lookup   Method   Injection\n\n            Lookup    method    injection   is the  ability of  the  container   to  override   methods     on  container-managed\n            beans   and  return   the  lookup    result  for another    named     bean   in the  container.    The  lookup    typically\n            involves a prototype bean, as in the scenario described in the preceding section. The Spring\n            Framework      implements     this  method    injection   by  using  bytecode    generation    from   the  CGLIB    library\n            to dynamically     generate   a  subclass   that overrides    the  method.\n\n                                • For  this  dynamic    subclassing    to  work,   the  class that  the  Spring   bean   container\n                                  subclasses    cannot   be  final,  and   the  method    to  be  overridden     cannot   be  final,\n                                  either.\n\n                                • Unit-testing    a class  that  has   an  abstract   method     requires    you  to  subclass   the\n                                  class  yourself   and  to supply   a stub  implementation       of the  abstract   method.\n                               • Concrete    methods     are  also necessary     for component      scanning,    which    requires\n                                  concrete   classes   to pick  up.\n\n                                • A further key limitation is that lookup methods do not work with factory\n                                  methods and in particular not with @Bean methods in configuration classes,\n                                  since,  in  that  case, the  container    is not  in  charge   of  creating   the  instance   and\n                                  therefore   cannot    create  a runtime-generated        subclass   on  the fly.\n\n\n            In the case of the CommandManager class in the previous code snippet, the Spring container\n            dynamically     overrides    the implementation       of the  createCommand()      method.    The  CommandManager     class\n            does  not  have   any  Spring   dependencies,     as the  reworked     example    shows:\n\n\n            Java\n\n\n              package    fiona.apple;\n\n\n              //  no   more  Spring    imports!\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         //  grab   a  new   instance    of  the   appropriate     Command    interface\n                         Command    command    =  createCommand();\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    //  okay...    but  where    is  the  implementation       of  this   method?\n                    protected     abstract    Command    createCommand();\n              }\n\n            Kotlin\n\n\n              package    fiona.apple\n\n\n              //  no   more  Spring    imports!\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         //  grab   a  new   instance    of  the   appropriate     Command    interface\n                         val   command    =  createCommand()\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    //  okay...    but  where    is  the  implementation       of  this   method?\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            In the client class that contains the method to be injected (the CommandManager in this case), the\n            method    to be  injected  requires    a signature   of the  following    form:\n\n\n\n              <public|protected>        [abstract]      <return-type>      theMethodName(no-arguments);\n\n\n\n            If  the  method   is abstract,   the  dynamically-generated         subclass   implements      the  method.    Otherwise,\n            the dynamically-generated subclass overrides the concrete method defined in the original class.\n            Consider   the  following    example:\n\n\n\n              <!--   a  stateful    bean   deployed     as  a prototype     (non-singleton)       -->\n              <bean    id=\"myCommand\"      class=\"fiona.apple.AsyncCommand\"              scope=\"prototype\">\n                    <!--   inject   dependencies      here   as  required     -->\n              </bean>\n\n\n              <!--   commandProcessor        uses  statefulCommandHelper          -->\n              <bean    id=\"commandManager\"        class=\"fiona.apple.CommandManager\">\n                    <lookup-method      name=\"createCommand\"         bean=\"myCommand\"/>\n              </bean>\n\n\n\n            The bean identified as commandManager calls its own createCommand() method whenever it needs a\n            new   instance   of the  myCommand   bean.   You  must   be  careful  to deploy   the  myCommand    bean   as a prototype\n            if that is actually what is needed. If it is a singleton, the same instance of the myCommand bean is\n            returned   each   time.\n\n\n            Alternatively, within the annotation-based component model, you can declare a lookup method\n            through   the  @Lookup   annotation,    as the  following   example     shows:\n\n            Java\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         Command    command    =  createCommand();\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    @Lookup(\"myCommand\")\n                    protected     abstract    Command    createCommand();\n              }\n\n\n\n            Kotlin\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         val   command    =  createCommand()\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    @Lookup(\"myCommand\")\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            Or, more    idiomatically,   you   can  rely on  the  target  bean   getting   resolved   against   the  declared   return\n            type  of the lookup    method:\n\n\n            Java\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         Command    command    =  createCommand();\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    @Lookup\n                    protected     abstract    Command    createCommand();\n              }\n\n            Kotlin\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         val   command    =  createCommand()\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    @Lookup\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            Note that you should typically declare such annotated lookup methods with a concrete stub\n            implementation,      in order   for them    to be  compatible    with   Spring’s  component      scanning    rules  where\n            abstract classes get ignored by default. This limitation does not apply to explicitly registered or\n            explicitly  imported    bean   classes.\n\n\n                              Another way of accessing differently scoped target beans is an ObjectFactory/\n                              Provider   injection  point.  See  Scoped    Beans   as Dependencies.\n                 \n                              You       may        also      find       the       ServiceLocatorFactoryBean             (in      the\n                              org.springframework.beans.factory.config             package)    to be useful.\n\n\n\n            Arbitrary  Method   Replacement\n\n            A less useful form of method injection than lookup method injection is the ability to replace\n            arbitrary   methods     in a  managed     bean    with  another    method     implementation.       You  can   safely  skip\n            the rest  of this section   until you   actually  need   this functionality.\n\n\n            With XML-based configuration metadata, you can use the replaced-method element to replace an\n            existing  method     implementation       with   another,   for  a  deployed    bean.   Consider    the  following    class,\n            which   has  a method    called  computeValue     that  we  want   to override:\n\n\n            Java\n\n\n              public    class   MyValueCalculator        {\n\n\n                    public   String    computeValue(String         input)   {\n                         //  some   real   code...\n                    }\n\n\n                    //  some   other   methods...\n              }\n\n            Kotlin\n\n\n              class    MyValueCalculator       {\n\n\n                    fun  computeValue(input:         String):    String    {\n                         //  some   real   code...\n                    }\n\n\n                    //  some   other   methods...\n              }\n\n\n\n            A class that implements the org.springframework.beans.factory.support.MethodReplacer interface\n            provides   the  new   method    definition,   as the  following   example     shows:\n\n\n            Java\n\n\n              /**\n               *  meant    to  be  used   to  override    the   existing    computeValue(String)\n               *  implementation       in  MyValueCalculator\n               */\n              public    class   ReplacementComputeValue          implements     MethodReplacer       {\n\n\n                    public   Object    reimplement(Object        o,  Method    m,  Object[]    args)    throws   Throwable     {\n                         //  get   the  input    value,   work   with   it,   and  return    a computed     result\n                         String    input   =  (String)    args[0];\n                         ...\n                         return    ...;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              /**\n               *  meant    to  be  used   to  override    the   existing    computeValue(String)\n               *  implementation       in  MyValueCalculator\n               */\n              class    ReplacementComputeValue          : MethodReplacer       {\n\n\n                    override    fun   reimplement(obj:       Any,   method:    Method,    args:   Array<out     Any>):    Any  {\n                         //  get   the  input    value,   work   with   it,   and  return    a computed     result\n                         val   input   =  args[0]    as  String;\n                         ...\n                         return    ...;\n                    }\n              }\n\n\n\n            The  bean   definition    to deploy   the  original   class  and   specify   the  method    override    would    resemble\n            the following    example:\n\n              <bean    id=\"myValueCalculator\"         class=\"x.y.z.MyValueCalculator\">\n                    <!--   arbitrary    method    replacement      -->\n                    <replaced-method       name=\"computeValue\"         replacer=\"replacementComputeValue\">\n                         <arg-type>String</arg-type>\n                    </replaced-method>\n              </bean>\n\n\n              <bean    id=\"replacementComputeValue\"           class=\"a.b.c.ReplacementComputeValue\"/>\n\n\n\n            You  can   use  one   or more    <arg-type/>    elements     within   the  <replaced-method/>       element    to indicate\n            the method signature of the method being overridden. The signature for the arguments is\n            necessary only if the method is overloaded and multiple variants exist within the class. For\n            convenience,     the  type  string  for  an  argument     may   be  a  substring   of  the  fully qualified   type   name.\n            For example,    the  following    all  match  java.lang.String:\n\n\n\n              java.lang.String\n              String\n              Str\n\n\n\n            Because   the  number     of arguments     is often  enough     to distinguish   between     each  possible   choice,   this\n            shortcut can save a lot of typing, by letting you type only the shortest string that matches an\n            argument     type.\n\n            2.1.5.   Bean     Scopes\n\n            When    you   create   a bean   definition,   you   create   a recipe   for  creating   actual   instances    of the  class\n            defined   by  that  bean   definition.   The  idea  that  a bean   definition    is a recipe   is  important,   because   it\n            means   that,  as with   a class, you  can  create   many    object  instances   from   a single  recipe.\n\n\n            You  can  control   not  only  the  various   dependencies      and   configuration     values   that are  to  be plugged\n            into an object that is created from a particular bean definition but also control the scope of the\n            objects  created   from    a particular   bean   definition.   This   approach    is powerful     and  flexible,  because\n            you  can  choose    the scope   of  the objects   you  create   through    configuration    instead   of  having   to bake\n            in the  scope   of  an  object  at  the  Java  class  level.  Beans   can   be  defined   to  be  deployed    in  one  of  a\n            number     of scopes.   The  Spring    Framework      supports    six scopes,   four   of which    are  available   only  if\n            you  use  a web-aware      ApplicationContext.      You  can  also  create  a custom    scope.\n\n            The  following   table  describes    the supported     scopes:\n\n\n            Table 3.

This  single\n            instance   is stored   in a  cache   of such   singleton    beans,   and  all subsequent      requests   and   references\n            for that  named    bean   return   the  cached    object.  The  following    image   shows    how   the  singleton   scope\n            works:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n            Spring’s   concept   of  a singleton    bean   differs  from    the  singleton   pattern   as  defined    in the  Gang    of\n            Four  (GoF)   patterns    book.  The   GoF   singleton   hard-codes     the  scope   of  an  object  such   that  one  and\n\n            only  one  instance   of  a particular   class  is created   per  ClassLoader.     The  scope   of the  Spring   singleton\n            is  best  described  as being   per-container     and   per-bean.   This  means    that,  if  you  define one  bean   for  a\n            particular   class in  a single  Spring   container,   the  Spring   container    creates  one   and  only  one   instance\n            of the  class  defined   by  that  bean   definition.   The   singleton   scope   is the  default   scope   in Spring.   To\n            define  a bean   as  a singleton   in XML,   you   can  define  a bean   as  shown    in the  following   example:\n\n\n\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"/>\n\n\n              <!--   the   following    is   equivalent,     though    redundant    (singleton      scope   is  the  default)\n              -->\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"\n              scope=\"singleton\"/>\n\n\n\n\n            The  Prototype     Scope\n\n            The non-singleton prototype scope of bean deployment results in the creation of a new bean\n            instance every time a request for that specific bean is made. That is, the bean is injected into\n            another    bean   or  you  request    it through    a getBean()    method     call on  the  container.    As  a  rule,  you\n            should   use  the prototype    scope   for all stateful  beans   and   the singleton   scope   for  stateless  beans.\n\n\n            The  following   diagram     illustrates  the Spring   prototype    scope:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n            (A data   access  object   (DAO)   is not  typically   configured    as  a prototype,    because    a  typical  DAO    does\n            not hold   any  conversational     state. It was   easier  for us  to reuse  the  core  of the  singleton   diagram.)\n\n            The  following   example     defines   a bean   as a prototype    in XML:\n\n\n\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"\n              scope=\"prototype\"/>\n\n\n\n            In contrast   to the  other   scopes,  Spring   does   not  manage     the complete     lifecycle  of a prototype    bean.\n\n            The  container    instantiates,   configures,    and  otherwise     assembles    a  prototype    object  and   hands   it to\n            the client,  with   no  further   record   of that  prototype    instance.   Thus,   although    initialization   lifecycle\n            callback   methods    are  called  on  all objects   regardless    of scope,  in  the case  of  prototypes,    configured\n            destruction lifecycle callbacks are not called. The client code must clean up prototype-scoped\n            objects  and   release  expensive     resources    that  the  prototype    beans   hold.  To  get the  Spring   container\n            to release  resources    held  by  prototype-scoped      beans,   try  using  a custom    bean   post-processor,     which\n            holds  a reference    to beans   that  need   to be cleaned    up.\n\n\n            In some   respects,   the  Spring   container’s   role  in  regard   to a prototype-scoped       bean  is a  replacement\n            for the  Java  new  operator.    All lifecycle  management        past  that  point  must    be  handled    by  the  client.\n            (For details  on  the  lifecycle  of a bean   in the  Spring   container,   see  Lifecycle   Callbacks.)\n\n\n            Singleton    Beans   with   Prototype-bean       Dependencies\n\n            When you use singleton-scoped beans with dependencies on prototype beans, be aware that\n            dependencies     are  resolved    at instantiation    time.  Thus,   if  you dependency-inject      a  prototype-scoped\n            bean into a singleton-scoped bean, a new prototype bean is instantiated and then dependency-\n            injected  into  the  singleton   bean.   The  prototype    instance    is  the  sole  instance that  is ever  supplied    to\n            the singleton-scoped      bean.\n\n\n            However,    suppose    you   want   the  singleton-scoped      bean   to acquire   a  new   instance   of the  prototype-\n            scoped bean repeatedly at runtime. You cannot dependency-inject a prototype-scoped bean into\n            your   singleton     bean,    because    that   injection    occurs    only    once,   when     the   Spring    container\n            instantiates the singleton bean and resolves and injects its dependencies. If you need a new\n            instance   of a prototype    bean   at runtime    more   than   once,  see Method     Injection.\n\n\n            Request,    Session,   Application,     and   WebSocket      Scopes\n\n            The  request,   session,   application,    and   websocket   scopes   are   available   only  if you   use  a web-aware\n            Spring ApplicationContext implementation (such as XmlWebApplicationContext). If you use these\n            scopes    with   regular     Spring    IoC   containers,     such   as   the   ClassPathXmlApplicationContext,           an\n            IllegalStateException       that complains     about   an  unknown     bean   scope   is thrown.\n\n\n\n            Initial  Web Configuration\n\n            To support the scoping of beans at the request, session, application, and websocket levels (web-\n            scoped beans), some minor initial configuration is required before you define your beans. (This\n            initial setup  is not  required   for  the standard    scopes:   singleton   and   prototype.)\n\n\n            How   you  accomplish     this  initial setup  depends    on  your   particular   Servlet  environment.\n\n\n            If  you access  scoped    beans   within   Spring   Web    MVC,   in effect,  within   a request   that  is processed    by\n            the  Spring   DispatcherServlet,      no  special   setup   is necessary.   DispatcherServlet       already   exposes    all\n            relevant   state.\n\n\n            If  you use  a  Servlet   web   container,    with  requests    processed    outside   of  Spring’s   DispatcherServlet\n            (for     example,        when        using      JSF      or      Struts),     you       need       to     register      the\n            org.springframework.web.context.request.RequestContextListener ServletRequestListener. This can\n            be done    programmatically       by  using   the WebApplicationInitializer         interface.   Alternatively,    add  the\n            following   declaration    to your   web   application’s   web.xml   file:\n\n              <web-app>\n                    ...\n                    <listener>\n                         <listener-class>\n                               org.springframework.web.context.request.RequestContextListener\n                         </listener-class>\n                    </listener>\n                    ...\n              </web-app>\n\n\n\n            Alternatively,     if   there    are    issues     with    your     listener     setup,    consider      using    Spring’s\n            RequestContextFilter.        The    filter   mapping       depends      on   the    surrounding       web     application\n            configuration,    so you   have   to change    it  as  appropriate.  The  following    listing shows    the  filter part  of\n            a web   application:\n\n\n\n              <web-app>\n                    ...\n                    <filter>\n                         <filter-name>requestContextFilter</filter-name>\n                         <filter-class>org.springframework.web.filter.RequestContextFilter</filter-\n              class>\n                    </filter>\n                    <filter-mapping>\n                         <filter-name>requestContextFilter</filter-name>\n                         <url-pattern>/*</url-pattern>\n                    </filter-mapping>\n                    ...\n              </web-app>\n\n\n\n            DispatcherServlet,     RequestContextListener,        and   RequestContextFilter       all do  exactly   the  same   thing,\n            namely    bind  the  HTTP    request   object  to  the  Thread  that  is servicing   that  request.   This  makes    beans\n            that are  request-   and  session-scoped      available   further  down    the  call chain.\n\n\n\n            Request  scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"loginAction\"       class=\"com.something.LoginAction\"              scope=\"request\"/>\n\n\n\n            The  Spring   container    creates   a new   instance   of  the LoginAction     bean   by using   the  loginAction    bean\n            definition for each and every HTTP request. That is, the loginAction bean is scoped at the HTTP\n            request   level. You  can   change   the  internal   state of  the instance    that is created   as  much   as  you  want,\n            because other instances created from the same loginAction bean definition do not see these\n            changes in state. They are particular to an individual request. When the request completes\n            processing,   the  bean   that is scoped   to  the request   is discarded.\n\n\n            When    using  annotation-driven       components      or Java  configuration,     the  @RequestScope    annotation     can\n\n            be used   to assign  a  component     to the  request   scope.  The   following   example     shows   how   to do  so:\n\n\n            Java\n\n\n              @RequestScope\n              @Component\n              public    class   LoginAction      {\n                    //  ...\n              }\n\n\n\n            Kotlin\n\n\n              @RequestScope\n              @Component\n              class    LoginAction     {\n                    //  ...\n              }\n\n\n\n\n            Session  Scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\"/>\n\n\n\n            The   Spring     container     creates    a  new     instance    of   the   UserPreferences       bean    by   using    the\n            userPreferences bean definition for the lifetime of a single HTTP Session. In other words, the\n            userPreferences     bean   is effectively   scoped   at the  HTTP    Session   level. As  with   request-scoped     beans,\n            you  can  change    the  internal  state  of the  instance   that  is created   as much    as you   want,   knowing    that\n            other  HTTP    Session   instances    that  are  also  using  instances    created   from   the  same    userPreferences\n            bean  definition    do not  see  these  changes    in state,  because   they   are particular    to an  individual   HTTP\n            Session.  When     the  HTTP   Session   is eventually    discarded,    the  bean   that  is scoped   to  that  particular\n            HTTP   Session   is also discarded.\n\n\n            When using annotation-driven components or Java configuration, you can use the @SessionScope\n            annotation    to assign   a component      to the session   scope.\n\n\n            Java\n\n\n              @SessionScope\n              @Component\n              public    class   UserPreferences       {\n                    //  ...\n              }\n\n            Kotlin\n\n\n              @SessionScope\n              @Component\n              class    UserPreferences       {\n                    //  ...\n              }\n\n\n\n\n            Application  Scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"appPreferences\"        class=\"com.something.AppPreferences\"               scope=\"application\"/>\n\n\n\n            The  Spring   container    creates  a  new   instance   of the  AppPreferences     bean   by  using  the  appPreferences\n            bean  definition   once   for the  entire  web   application.    That  is, the appPreferences     bean   is scoped   at the\n            ServletContext     level  and  stored   as a  regular   ServletContext     attribute.  This  is somewhat      similar   to a\n            Spring  singleton    bean  but  differs  in two   important    ways:   It is  a singleton  per ServletContext,     not  per\n            Spring   ApplicationContext      (for  which   there   may   be  several   in any   given  web   application),    and   it  is\n            actually  exposed    and   therefore   visible  as a ServletContext     attribute.\n\n\n            When      using     annotation-driven        components         or   Java     configuration,      you     can    use    the\n            @ApplicationScope annotation to assign a component to the application scope. The following\n            example    shows   how    to do so:\n\n\n            Java\n\n\n              @ApplicationScope\n              @Component\n              public    class   AppPreferences       {\n                    //  ...\n              }\n\n\n\n            Kotlin\n\n\n              @ApplicationScope\n              @Component\n              class    AppPreferences      {\n                    //  ...\n              }\n\n\n\n\n            WebSocket    Scope\n\n            WebSocket     scope   is associated   with   the  lifecycle  of a WebSocket      session  and   applies   to STOMP     over\n            WebSocket     applications,   see  WebSocket     scope   for  more   details.\n\n            Scoped  Beans   as Dependencies\n\n            The  Spring   IoC  container     manages     not  only  the  instantiation    of  your   objects  (beans),   but  also  the\n            wiring   up  of collaborators     (or dependencies).      If  you want   to inject  (for  example)    an  HTTP    request-\n            scoped   bean   into  another    bean   of a  longer-lived    scope,  you   may   choose    to inject  an  AOP   proxy    in\n            place  of  the  scoped   bean.   That   is,  you need   to  inject  a proxy    object  that  exposes    the  same   public\n            interface as the scoped object but that can also retrieve the real target object from the relevant\n            scope  (such   as an  HTTP   request)   and   delegate   method    calls  onto  the  real object.\n\n\n                              You  may   also  use  <aop:scoped-proxy/>       between    beans   that  are  scoped   as  singleton,\n                              with  the  reference    then   going   through    an  intermediate     proxy    that  is serializable\n                              and  therefore   able  to  re-obtain   the target  singleton    bean  on  deserialization.\n\n\n                              When declaring <aop:scoped-proxy/> against a bean of scope prototype, every\n                              method    call on  the  shared    proxy   leads   to the  creation   of a  new   target  instance    to\n                              which   the  call is  then being  forwarded.\n\n                              Also, scoped    proxies   are  not  the only   way   to access  beans    from   shorter   scopes  in  a\n                              lifecycle-safe fashion. You may also declare your injection point (that is, the\n                             constructor    or setter  argument     or  autowired    field)  as ObjectFactory<MyTargetBean>,\n                              allowing   for  a  getObject()    call to  retrieve   the  current   instance    on  demand     every\n                              time  it  is  needed — without    holding    on to  the instance   or  storing  it separately.\n\n\n                              As an extended variant, you may declare ObjectProvider<MyTargetBean> which\n                              delivers    several     additional     access     variants,    including      getIfAvailable      and\n                              getIfUnique.\n\n\n                              The    JSR-330     variant     of   this    is   called    Provider     and     is   used    with     a\n                              Provider<MyTargetBean> declaration and a corresponding get() call for every\n                              retrieval  attempt.   See  here  for  more   details  on  JSR-330   overall.\n\n\n            The  configuration     in  the following    example     is only  one   line, but  it is important    to  understand     the\n            “why”   as well  as  the “how”    behind   it:\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:aop=\"http://www.springframework.org/schema/aop\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\n                         http://www.springframework.org/schema/aop\n                         https://www.springframework.org/schema/aop/spring-aop.xsd\">\n\n\n                    <!--   an  HTTP   Session-scoped      bean   exposed    as  a  proxy   -->\n                    <bean   id=\"userPreferences\"         class=\"com.something.UserPreferences\"               scope=\"session\">\n                         <!--   instructs     the  container     to  proxy    the  surrounding      bean  -->\n                         <aop:scoped-proxy/>         ①\n                    </bean>\n\n\n                    <!--   a singleton-scoped        bean   injected    with   a  proxy   to  the   above   bean   -->\n                    <bean   id=\"userService\"       class=\"com.something.SimpleUserService\">\n                         <!--   a  reference     to  the  proxied    userPreferences       bean   -->\n                         <property     name=\"userPreferences\"          ref=\"userPreferences\"/>\n                    </bean>\n              </beans>\n\n\n            ① The    line that  defines   the proxy.\n\n            To create   such  a proxy,   you  insert  a child  <aop:scoped-proxy/>       element    into  a scoped   bean   definition\n            (see Choosing the Type of Proxy to Create and XML Schema-based configuration). Why do\n            definitions   of beans   scoped   at  the request,   session   and  custom-scope      levels  require   the  <aop:scoped-\n            proxy/> element? Consider the following singleton bean definition and contrast it with what you\n            need to define for the aforementioned scopes (note that the following userPreferences bean\n            definition   as it  stands is incomplete):\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\"/>\n\n\n              <bean    id=\"userManager\"       class=\"com.something.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n            In the  preceding    example,    the  singleton   bean   (userManager)    is injected   with  a  reference   to  the HTTP\n            Session-scoped bean (userPreferences). The salient point here is that the userManager bean is a\n            singleton:   it  is  instantiated exactly   once   per  container,   and   its dependencies      (in this case   only  one,\n            the userPreferences bean) are also injected only once. This means that the userManager bean\n            operates   only  on  the  exact  same   userPreferences      object  (that  is,  the  one  with which   it was  originally\n            injected).\n\n            This  is not  the  behavior    you   want   when    injecting   a  shorter-lived    scoped    bean   into  a longer-lived\n            scoped   bean   (for  example,    injecting   an   HTTP   Session-scoped      collaborating     bean   as  a dependency\n            into singleton    bean).  Rather,   you   need   a single  userManager     object,  and,  for  the lifetime   of an  HTTP\n            Session,  you   need   a userPreferences      object  that  is specific  to the  HTTP    Session.   Thus,  the  container\n\n            creates  an  object   that  exposes   the  exact   same   public   interface   as  the  UserPreferences     class  (ideally\n            an  object  that  is a UserPreferences      instance),   which    can  fetch  the  real  UserPreferences      object  from\n            the scoping mechanism (HTTP request, Session, and so forth). The container injects this proxy\n            object  into the  userManager    bean,   which   is unaware     that  this UserPreferences     reference    is a proxy.   In\n            this  example,     when     a   UserManager     instance     invokes    a   method     on   the   dependency-injected\n            UserPreferences     object,  it is actually   invoking    a  method     on  the  proxy.   The  proxy    then  fetches   the\n            real UserPreferences object from (in this case) the HTTP Session and delegates the method\n            invocation    onto  the  retrieved   real UserPreferences      object.\n\n            Thus, you need the following (correct and complete) configuration when injecting request- and\n            session-scoped     beans   into collaborating     objects,  as the  following   example    shows:\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\">\n                    <aop:scoped-proxy/>\n              </bean>\n\n\n              <bean    id=\"userManager\"       class=\"com.something.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n\n            Choosing    the  Type   of  Proxy   to  Create\n\n            By default, when the Spring container creates a proxy for a bean that is marked up with the\n            <aop:scoped-proxy/>      element,    a CGLIB-based     class  proxy   is created.\n\n\n                              CGLIB   proxies   intercept    only  public   method    calls! Do   not  call non-public    methods\n                             on such   a proxy.   They  are  not  delegated    to the  actual  scoped   target  object.\n\n\n            Alternatively, you can configure the Spring container to create standard JDK interface-based\n            proxies   for such   scoped   beans,   by  specifying   false   for the  value   of the  proxy-target-class      attribute\n            of the  <aop:scoped-proxy/>      element.    Using   JDK  interface-based      proxies   means    that  you  do  not  need\n            additional   libraries   in your   application    classpath    to affect  such   proxying.    However,     it also  means\n            that the  class  of  the  scoped   bean   must    implement     at  least one   interface   and   that  all collaborators\n            into which    the  scoped    bean   is injected   must   reference    the  bean   through    one  of  its interfaces.   The\n            following   example    shows    a proxy   based   on  an  interface:\n\n\n\n              <!--   DefaultUserPreferences          implements     the  UserPreferences       interface     -->\n              <bean    id=\"userPreferences\"        class=\"com.stuff.DefaultUserPreferences\"                 scope=\"session\">\n                    <aop:scoped-proxy        proxy-target-class=\"false\"/>\n              </bean>\n\n\n              <bean    id=\"userManager\"       class=\"com.stuff.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n            For   more    detailed    information      about    choosing     class-based     or  interface-based      proxying,     see\n            Proxying    Mechanisms.\n\n            Custom    Scopes\n\n            The bean scoping mechanism is extensible. You can define your own scopes or even redefine\n            existing  scopes,   although    the  latter is considered     bad  practice   and   you  cannot    override   the  built-in\n            singleton   and   prototype   scopes.\n\n\n\n            Creating  a Custom   Scope\n\n            To   integrate    your    custom     scopes    into   the   Spring    container,     you    need    to   implement      the\n            org.springframework.beans.factory.config.Scope               interface,  which    is  described  in  this section.  For  an\n            idea  of how    to implement     your   own    scopes,  see  the  Scope   implementations       that  are  supplied    with\n            the Spring Framework itself and the Scope javadoc, which explains the methods you need to\n            implement     in more   detail.\n\n\n            The  Scope   interface   has  four  methods     to  get objects   from   the  scope,   remove    them    from   the  scope,\n            and  let them   be  destroyed.\n\n\n            The session scope implementation, for example, returns the session-scoped bean (if it does not\n            exist, the  method    returns   a new   instance   of  the bean,   after  having   bound    it  to  the  session  for  future\n            reference).   The  following    method    returns   the  object  from   the underlying     scope:\n\n\n            Java\n\n\n              Object    get(String     name,   ObjectFactory<?>        objectFactory)\n\n\n\n            Kotlin\n\n\n              fun   get(name:     String,    objectFactory:      ObjectFactory<*>):        Any\n\n\n\n            The session scope implementation, for example, removes the session-scoped bean from the\n            underlying    session.   The   object  should    be  returned,    but  you  can   return   null  if the  object   with  the\n            specified  name    is not  found.  The   following   method     removes    the  object  from   the underlying     scope:\n\n\n            Java\n\n\n              Object    remove(String      name)\n\n\n\n            Kotlin\n\n\n              fun   remove(name:      String):    Any\n\n\n\n            The following method registers a callback that the scope should invoke when it is destroyed or\n            when   the  specified   object  in the  scope   is  destroyed:\n\n\n            Java\n\n\n              void   registerDestructionCallback(String              name,    Runnable    destructionCallback)\n\n            Kotlin\n\n\n              fun   registerDestructionCallback(name:              String,    destructionCallback:        Runnable)\n\n\n\n            See the  javadoc   or  a Spring   scope   implementation      for  more   information     on  destruction    callbacks.\n\n            The  following   method     obtains   the conversation     identifier   for the  underlying    scope:\n\n\n            Java\n\n\n              String    getConversationId()\n\n\n\n            Kotlin\n\n\n              fun   getConversationId():         String\n\n\n\n            This  identifier  is different   for  each   scope.  For  a  session   scoped   implementation,       this identifier   can\n            be the  session   identifier.\n\n\n\n            Using a Custom    Scope\n\n            After  you  write   and   test one  or  more   custom    Scope   implementations,       you  need   to make    the  Spring\n            container   aware    of your   new   scopes.   The  following    method    is the  central   method    to register   a new\n            Scope  with  the  Spring   container:\n\n\n            Java\n\n\n              void   registerScope(String         scopeName,     Scope   scope);\n\n\n\n            Kotlin\n\n\n              fun   registerScope(scopeName:          String,    scope:    Scope)\n\n\n\n            This  method     is declared   on   the  ConfigurableBeanFactory        interface,   which    is available   through    the\n            BeanFactory property on most of the concrete ApplicationContext implementations that ship with\n            Spring.\n\n\n            The  first argument      to the  registerScope(..)       method    is the  unique    name    associated    with   a  scope.\n            Examples of such names in the Spring container itself are singleton and prototype. The second\n            argument      to   the   registerScope(..)        method      is   an   actual    instance     of   the   custom      Scope\n            implementation      that  you  wish   to register  and   use.\n\n            Suppose that you write your custom Scope implementation, and then register it as shown in the\n            next  example.\n\n                              The  next  example     uses  SimpleThreadScope,      which   is included    with  Spring   but  is not\n                             registered by default. The instructions would be the same for your own custom\n                              Scope  implementations.\n\n\n            Java\n\n\n              Scope    threadScope     =  new  SimpleThreadScope();\n              beanFactory.registerScope(\"thread\",               threadScope);\n\n\n\n            Kotlin\n\n\n              val   threadScope     =  SimpleThreadScope()\n              beanFactory.registerScope(\"thread\",               threadScope)\n\n\n\n            You can then create bean definitions that adhere to the scoping rules of your custom Scope, as\n            follows:\n\n\n\n              <bean    id=\"...\"    class=\"...\"     scope=\"thread\">\n\n\n\n            With  a  custom   Scope   implementation,      you  are  not  limited   to programmatic      registration    of the  scope.\n            You  can  also  do  the  Scope  registration   declaratively,    by  using  the  CustomScopeConfigurer       class,  as the\n            following   example    shows:\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:aop=\"http://www.springframework.org/schema/aop\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\n                         http://www.springframework.org/schema/aop\n                         https://www.springframework.org/schema/aop/spring-aop.xsd\">\n\n\n                    <bean   class=\"org.springframework.beans.factory.config.CustomScopeConfigurer\">\n                         <property     name=\"scopes\">\n                               <map>\n                                    <entry    key=\"thread\">\n                                          <bean\n              class=\"org.springframework.context.support.SimpleThreadScope\"/>\n                                    </entry>\n                               </map>\n                         </property>\n                    </bean>\n\n\n                    <bean   id=\"thing2\"      class=\"x.y.Thing2\"        scope=\"thread\">\n                         <property     name=\"name\"      value=\"Rick\"/>\n                         <aop:scoped-proxy/>\n                    </bean>\n\n\n                    <bean   id=\"thing1\"      class=\"x.y.Thing1\">\n                         <property     name=\"thing2\"      ref=\"thing2\"/>\n                    </bean>\n\n\n              </beans>\n\n\n\n\n                              When    you  place   <aop:scoped-proxy/>       within   a <bean>   declaration    for a  FactoryBean\n                             implementation,      it is the factory   bean   itself that  is scoped,   not  the  object  returned\n                              from  getObject().\n\n\n            2.1.6.   Customizing          the   Nature       of  a Bean\n\n            The  Spring   Framework       provides    a number     of  interfaces   you   can  use  to  customize    the  nature   of  a\n            bean.  This  section   groups   them   as follows:\n\n              • Lifecycle   Callbacks\n\n              • ApplicationContextAware        and  BeanNameAware\n\n              • Other   Aware  Interfaces\n\n\n            Lifecycle   Callbacks\n\n            To  interact  with   the  container’s    management       of  the bean    lifecycle,  you  can   implement     the  Spring\n            InitializingBean and DisposableBean interfaces. The container calls afterPropertiesSet() for the\n\n            former   and   destroy()    for the  latter  to let the  bean   perform     certain  actions   upon    initialization  and\n            destruction    of your  beans.\n\n\n                              The  JSR-250   @PostConstruct      and  @PreDestroy     annotations     are  generally   considered\n                              best practice   for receiving    lifecycle  callbacks   in a modern     Spring   application.   Using\n                              these annotations means that your beans are not coupled to Spring-specific\n                             interfaces.  For  details,  see Using   @PostConstruct     and   @PreDestroy.\n\n\n                              If you do not want to use the JSR-250 annotations but you still want to remove\n                              coupling,   consider   init-method    and   destroy-method     bean   definition   metadata.\n\n\n            Internally,  the  Spring   Framework       uses  BeanPostProcessor       implementations       to process   any   callback\n            interfaces it can find and call the appropriate methods. If you need custom features or other\n            lifecycle  behavior    Spring  does   not  by default   offer, you   can  implement     a BeanPostProcessor      yourself.\n            For more    information,    see  Container    Extension    Points.\n\n\n            In addition to the initialization and destruction callbacks, Spring-managed objects may also\n            implement     the  Lifecycle   interface   so  that those   objects  can  participate    in the  startup  and   shutdown\n            process,  as  driven   by the  container’s    own   lifecycle.\n\n\n            The  lifecycle  callback   interfaces   are  described    in this section.\n\n\n\n            Initialization Callbacks\n\n            The     org.springframework.beans.factory.InitializingBean                   interface     lets    a    bean      perform\n            initialization    work    after   the   container     has   set   all  necessary     properties     on   the   bean.    The\n            InitializingBean     interface   specifies   a single  method:\n\n\n\n              void   afterPropertiesSet()         throws    Exception;\n\n\n\n            We  recommend       that  you  do  not  use  the InitializingBean      interface,   because   it unnecessarily     couples\n            the code to Spring. Alternatively, we suggest using the @PostConstruct annotation or specifying a\n            POJO   initialization  method.    In  the  case  of XML-based      configuration    metadata,    you   can  use  the  init-\n            method attribute to specify the name of the method that has a void no-argument signature. With\n            Java  configuration,    you   can  use  the  initMethod    attribute   of @Bean.  See  Receiving    Lifecycle   Callbacks.\n            Consider   the  following    example:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.ExampleBean\"            init-method=\"init\"/>\n\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    public   void   init()    {\n                         //  do   some  initialization       work\n                    }\n              }\n\n            Kotlin\n\n\n              class    ExampleBean     {\n\n\n                    fun  init()    {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            The  preceding    example     has  almost   exactly  the  same   effect  as the  following    example    (which   consists\n            of two  listings):\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.AnotherExampleBean\"/>\n\n\n\n            Java\n\n\n              public    class   AnotherExampleBean        implements     InitializingBean        {\n\n\n                    @Override\n                    public   void   afterPropertiesSet()         {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    AnotherExampleBean        : InitializingBean        {\n\n\n                    override    fun   afterPropertiesSet()         {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            However,    the  first of the  two  preceding    examples     does  not  couple   the  code  to Spring.\n\n\n\n            Destruction   Callbacks\n\n            Implementing the org.springframework.beans.factory.DisposableBean interface lets a bean get a\n            callback   when    the  container    that  contains   it is destroyed.    The   DisposableBean     interface   specifies   a\n            single  method:\n\n\n\n              void   destroy()     throws    Exception;\n\n\n\n            We  recommend       that  you   do  not  use  the DisposableBean      callback   interface,  because    it unnecessarily\n            couples   the  code  to Spring.   Alternatively,    we  suggest   using   the @PreDestroy     annotation    or  specifying\n            a generic   method     that  is supported     by  bean   definitions.   With   XML-based      configuration     metadata,\n            you  can   use  the  destroy-method     attribute   on  the  <bean/>.   With   Java  configuration,     you   can  use  the\n\n            destroyMethod      attribute    of  @Bean.   See    Receiving     Lifecycle    Callbacks.    Consider     the   following\n            definition:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.ExampleBean\"            destroy-method=\"cleanup\"/>\n\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    public   void   cleanup()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     {\n\n\n                    fun  cleanup()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            The  preceding    definition   has  almost   exactly   the same    effect as  the following    definition:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.AnotherExampleBean\"/>\n\n\n\n            Java\n\n\n              public    class   AnotherExampleBean        implements     DisposableBean       {\n\n\n                    @Override\n                    public   void   destroy()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    AnotherExampleBean        : DisposableBean       {\n\n\n                    override    fun   destroy()    {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n            However,    the  first of the  two  preceding    definitions   does   not  couple   the code   to Spring.\n\n\n                              You  can  assign   the destroy-method     attribute   of a <bean>   element    a special  (inferred)\n                              value, which instructs Spring to automatically detect a public close or shutdown\n                              method       on     the    specific     bean      class.     (Any     class     that    implements\n                              java.lang.AutoCloseable or java.io.Closeable would therefore match.) You can\n                             also  set this  special  (inferred)    value   on  the  default-destroy-method        attribute   of  a\n                              <beans> element to apply this behavior to an entire set of beans (see Default\n                              Initialization  and   Destroy   Methods).    Note   that this  is  the  default behavior   with   Java\n                              configuration.\n\n\n\n            Default  Initialization and  Destroy  Methods\n\n            When you write initialization and destroy method callbacks that do not use the Spring-specific\n            InitializingBean      and  DisposableBean      callback   interfaces,   you   typically   write  methods     with   names\n            such as init(), initialize(), dispose(), and so on. Ideally, the names of such lifecycle callback\n            methods    are  standardized      across  a  project  so  that  all developers    use   the same    method    names    and\n            ensure   consistency.\n\n\n            You can configure the Spring container to “look” for named initialization and destroy callback\n            method names on every bean. This means that you, as an application developer, can write your\n            application    classes  and   use  an  initialization   callback   called  init(),   without   having    to configure    an\n            init-method=\"init\"      attribute   with  each   bean   definition.   The  Spring    IoC container    calls  that  method\n            when   the  bean   is created   (and  in accordance     with   the standard    lifecycle  callback   contract   described\n            previously).   This  feature   also enforces    a consistent   naming     convention    for  initialization   and  destroy\n            method    callbacks.\n\n            Suppose that your initialization callback methods are named init() and your destroy callback\n            methods    are  named    destroy().   Your   class then   resembles    the  class  in the following    example:\n\n\n            Java\n\n\n              public    class   DefaultBlogService        implements     BlogService      {\n\n\n                    private    BlogDao    blogDao;\n\n\n                    public   void   setBlogDao(BlogDao        blogDao)     {\n                         this.blogDao      =  blogDao;\n                    }\n\n\n                    //  this   is  (unsurprisingly)       the   initialization      callback     method\n                    public   void   init()    {\n                         if  (this.blogDao       ==  null)   {\n                               throw   new   IllegalStateException(\"The           [blogDao]    property     must   be  set.\");\n                         }\n                    }\n              }\n\n            Kotlin\n\n\n              class    DefaultBlogService        : BlogService      {\n\n\n                    private    var  blogDao:     BlogDao?    =  null\n\n\n                    //  this   is  (unsurprisingly)       the   initialization      callback     method\n                    fun  init()    {\n                         if  (blogDao     ==  null)   {\n                               throw   IllegalStateException(\"The           [blogDao]     property    must   be  set.\")\n                         }\n                    }\n              }\n\n\n\n            You  could  then   use  that class  in a bean   resembling     the  following:\n\n\n\n              <beans    default-init-method=\"init\">\n\n\n                    <bean   id=\"blogService\"       class=\"com.something.DefaultBlogService\">\n                         <property     name=\"blogDao\"       ref=\"blogDao\"      />\n                    </bean>\n\n\n              </beans>\n\n\n\n            The  presence    of the  default-init-method      attribute   on  the  top-level  <beans/>    element   attribute   causes\n            the  Spring   IoC  container    to recognize     a method     called  init  on  the  bean    class  as the  initialization\n            method    callback.   When    a  bean   is  created  and  assembled,     if the bean    class has   such  a  method,    it  is\n            invoked   at the  appropriate     time.\n\n\n            You can configure destroy method callbacks similarly (in XML, that is) by using the default-\n            destroy-method     attribute  on  the  top-level  <beans/>    element.\n\n\n            Where    existing   bean   classes   already   have   callback    methods    that  are   named    at  variance    with  the\n            convention,    you   can  override   the  default   by  specifying   (in  XML,   that  is) the method     name    by using\n            the init-method    and   destroy-method     attributes   of the  <bean/>  itself.\n\n\n            The  Spring   container    guarantees    that  a configured    initialization   callback   is called  immediately     after\n            a bean   is supplied   with   all dependencies.     Thus,   the  initialization  callback    is  called on  the raw   bean\n            reference,   which   means    that  AOP   interceptors    and   so forth  are  not  yet  applied   to the  bean.  A  target\n            bean  is fully  created   first and  then  an  AOP   proxy   (for  example)    with  its interceptor    chain   is  applied.\n            If  the  target bean   and  the  proxy    are  defined   separately,   your   code   can  even   interact   with  the  raw\n            target  bean,   bypassing    the  proxy.   Hence,   it would    be  inconsistent    to  apply   the  interceptors    to the\n            init method, because doing so would couple the lifecycle of the target bean to its proxy or\n            interceptors and leave strange semantics when your code interacts directly with the raw target\n            bean."

    "content": "# ToolCallAdvisor Streaming Design Document\n\nThis document describes the design and implementation of streaming support in `ToolCallAdvisor`, particularly when used with external memory advisors like `MessageChatMemoryAdvisor`.\n\n## Problem Statement\n\nWhen using `ToolCallAdvisor` with `disableInternalConversationHistory()` and an external `MessageChatMemoryAdvisor`, the non-streaming (call) implementation works correctly, but the original streaming implementation failed due to:\n\n1. **Tool call detection on individual chunks**: The original implementation checked `hasToolCalls()` on each streaming chunk instead of the complete aggregated response\n2. **Race conditions with memory updates**: `MessageChatMemoryAdvisor.after()` fires via `doOnComplete` after all chunks are emitted, but tool call detection happened per-chunk, causing memory inconsistency\n3. **Incorrect recursion timing**: Recursive tool call iterations started before the current stream completed\n\n### Why Call (Non-Streaming) Works\n\nIn the synchronous call flow, each iteration waits for a **complete response** before checking for tool calls:\n\n```java\ndo {\n    chatClientResponse = callAdvisorChain.nextCall(request);\n    isToolCall = chatResponse != null && chatResponse.hasToolCalls();\n    if (isToolCall) {\n        // Execute tools and prepare next iteration\n    }\n} while (isToolCall);\n```\n\n### The Streaming Challenge\n\nStreaming responses arrive as individual chunks. We don't know if the response contains tool calls until we've aggregated the **complete** response, but we want to stream chunks in real-time.\n\n---\n\n## Solution: Parallel Streaming with Deferred Recursion\n\nThe solution uses `publish()` to multicast the stream, enabling parallel streaming and aggregation:\n\n```\nModel Stream ──► publish() ──┬──► streamingBranch ──► emit chunks immediately\n                             │\n                             └──► aggregation ──► detect tool calls ──► recurse if needed\n```\n\n### Implementation\n\nThe `internalStream` method handles each iteration:\n\n```java\nprivate Flux<ChatClientResponse> internalStream(StreamAdvisorChain streamAdvisorChain,\n        ChatClientRequest originalRequest, ToolCallingChatOptions optionsCopy, List<Message> instructions) {\n\n    return Flux.deferContextual(contextView -> {\n        var processedRequest = ChatClientRequest.builder()\n            .prompt(new Prompt(instructions, optionsCopy))\n            .context(originalRequest.context())\n            .build();\n\n        processedRequest = this.doBeforeStream(processedRequest, streamAdvisorChain);\n        Flux<ChatClientResponse> responseFlux = streamAdvisorChain.copy(this).nextStream(processedRequest);\n        AtomicReference<ChatClientResponse> aggregatedResponseRef = new AtomicReference<>();\n\n        return streamWithToolCallResponses(responseFlux, aggregatedResponseRef, processedRequest,\n                streamAdvisorChain, originalRequest, optionsCopy);\n    });\n}\n```\n\nThe `streamWithToolCallResponses` method uses `publish()` for parallel processing:\n\n```java\nprivate Flux<ChatClientResponse> streamWithToolCallResponses(Flux<ChatClientResponse> responseFlux,\n        AtomicReference<ChatClientResponse> aggregatedResponseRef, ChatClientRequest finalRequest,\n        StreamAdvisorChain streamAdvisorChain, ChatClientRequest originalRequest,\n        ToolCallingChatOptions optionsCopy) {\n\n    return responseFlux.publish(shared -> {\n        // Branch 1: Stream chunks immediately for real-time UX\n        Flux<ChatClientResponse> streamingBranch = new ChatClientMessageAggregator()\n            .aggregateChatClientResponse(shared, aggregatedResponseRef::set);\n\n        // Branch 2: After streaming completes, check for tool calls and recurse\n        Flux<ChatClientResponse> recursionBranch = Flux\n            .defer(() -> handleToolCallRecursion(aggregatedResponseRef.get(), finalRequest,\n                streamAdvisorChain, originalRequest, optionsCopy));\n\n        return streamingBranch.concatWith(recursionBranch);\n    })\n    .filter(ccr -> this.streamToolCallResponses\n            || !(ccr.chatResponse() != null && ccr.chatResponse().hasToolCalls()));\n}\n```\n\n### How It Works\n\n**For a tool call iteration:**\n```\nModel emits:  [chunk1] [chunk2] [chunk3:tool_call] [complete]\n                 │        │           │                │\nStreaming:    emit     emit        emit               │  ◄── Real-time to downstream\n                                                       │\nAggregation:  ─────────────────────────────────► complete\n                                                       │\n                                                       ▼\n                                                 detect tool call → execute → recurse\n```\n\n**For the final answer:**\n```\nModel emits:  [chunk1] [chunk2] ... [chunkN] [complete]\n                 │        │           │          │\nStreaming:    emit     emit        emit         │  ◄── Real-time to downstream\n                                                 │\nAggregation:  ───────────────────────────► complete\n                                                 │\n                                                 ▼\n                                           no tool call → done\n```\n\n---\n\n## Configuration: Filtering Tool Call Responses\n\nThe `streamToolCallResponses` option controls whether intermediate tool call responses are emitted downstream:\n\n```java\n// Default: Only stream final answer (tool call responses filtered out)\nToolCallAdvisor advisor = ToolCallAdvisor.builder().build();\n\n// Stream all chunks including intermediate tool calls\nToolCallAdvisor advisor = ToolCallAdvisor.builder()\n    .streamToolCallResponses(true)\n    .build();\n```\n\n| Configuration | Intermediate Tool Calls | Final Answer |\n|--------------|------------------------|--------------|\n| `streamToolCallResponses(false)` (default) | Filtered out | Streamed |\n| `streamToolCallResponses(true)` | Streamed | Streamed |\n\nThe filtering is implemented as a terminal filter on the stream:\n\n```java\n.filter(ccr -> this.streamToolCallResponses\n        || !(ccr.chatResponse() != null && ccr.chatResponse().hasToolCalls()))\n```\n\n### Use Cases\n\n- **API backend**: Use default to only receive the final answer\n- **Chat UI with progress feedback**: Use `streamToolCallResponses(true)` to show tool execution in real-time\n- **Debugging**: Use `streamToolCallResponses(true)` to see all intermediate responses\n\n---\n\n## Key Benefits\n\n1. **Real-time streaming**: Chunks are emitted immediately as they arrive\n2. **Correct tool call detection**: Based on aggregated response, not individual chunks\n3. **Memory consistency**: Aggregation completes before recursion, ensuring proper sequencing\n4. **Configurable output**: Filter intermediate tool calls based on use case\n5. **Simple implementation**: Single code path with terminal filter\n"

It verifies whether a given\n * statement (the \"claim\") is logically supported by a provided context (the \"document\").\n * <p>\n * Key concepts: - Document: The context or grounding information against which the claim\n * is checked. - Claim: The statement to be verified against the document.\n * <p>\n * The evaluator uses a prompt-based approach with a separate, typically smaller and more\n * efficient LLM to perform the fact-checking. This design choice allows for\n * cost-effective and rapid verification, which is crucial when evaluating longer LLM\n * outputs that may require multiple verification steps.\n * <p>\n * Implementation note: For efficient and accurate fact-checking, consider using\n * specialized models like Bespoke-Minicheck, a grounded factuality checking model\n * developed by Bespoke Labs and available in Ollama.

Spring              Framework                         Overview\n\n\n            Spring makes it easy to create Java enterprise applications. It provides everything you need to\n            embrace    the  Java   language    in  an  enterprise    environment,      with   support   for  Groovy    and   Kotlin   as\n            alternative languages on the JVM, and with the flexibility to create many kinds of architectures\n            depending     on  an  application’s    needs.  As  of  Spring   Framework      5.1, Spring   requires    JDK  8+  (Java  SE\n            8+) and provides out-of-the-box support for JDK 11 LTS. Java SE 8 update 60 is suggested as the\n            minimum      patch  release   for Java  8, but  it is  generally  recommended       to  use a  recent  patch   release.\n\n            Spring  supports    a wide   range   of application    scenarios.   In  a large  enterprise,   applications    often  exist\n            for a  long  time   and   have   to run   on  a  JDK  and   application    server   whose    upgrade     cycle  is beyond\n            developer    control.   Others   may    run  as  a single   jar with   the  server   embedded,      possibly   in  a cloud\n            environment.      Yet others   may    be standalone     applications    (such   as  batch   or integration    workloads)\n            that do  not  need   a server.\n\n\n            Spring  is open   source.   It  has  a large  and active  community      that  provides   continuous     feedback    based\n            on a  diverse   range  of  real-world   use  cases.  This  has  helped    Spring  to  successfully   evolve   over  a  very\n            long  time.\n\n            1.1.    What          We      Mean          by    \"Spring\"\n\n\n            The  term   \"Spring\"   means    different   things  in  different   contexts.  It can  be  used   to refer  to the  Spring\n            Framework      project   itself,  which  is where    it  all  started.  Over time,  other  Spring   projects   have   been\n            built on  top  of  the Spring    Framework.      Most   often,  when    people   say  \"Spring\",   they  mean    the  entire\n            family  of  projects.  This  reference    documentation       focuses   on  the foundation:     the  Spring   Framework\n            itself.\n\n\n            The  Spring   Framework      is divided   into  modules.    Applications     can  choose   which    modules    they  need.\n            At the heart are the modules of the core container, including a configuration model and a\n            dependency injection mechanism. Beyond that, the Spring Framework provides foundational\n            support    for   different    application     architectures,     including    messaging,      transactional     data   and\n            persistence, and web. It also includes the Servlet-based Spring MVC web framework and, in\n            parallel, the  Spring   WebFlux     reactive   web   framework.\n\n\n            A note about modules: Spring’s framework jars allow for deployment to JDK 9’s module path\n            (\"Jigsaw\"). For use in Jigsaw-enabled applications, the Spring Framework 5 jars come with\n            \"Automatic-Module-Name\" manifest entries which define stable language-level module names\n            (\"spring.core\",   \"spring.context\",     etc.) independent     from    jar artifact  names    (the  jars follow   the  same\n            naming    pattern   with   \"-\" instead   of  \".\",  e.g.  \"spring-core\"  and   \"spring-context\").    Of  course,   Spring’s\n            framework     jars  keep  working    fine  on  the  classpath   on  both  JDK  8  and  9+.\n\n            1.2.    History            of   Spring          and       the      Spring          Framework\n\n\n            Spring came into being in 2003 as a response to the complexity of the early J2EE specifications.\n            While   some    consider   Java   EE  and   its modern-day      successor    Jakarta   EE  to  be  in  competition     with\n            Spring, they are in fact complementary. The Spring programming model does not embrace the\n            Jakarta    EE   platform      specification;    rather,    it  integrates     with    carefully    selected    individual\n\n            specifications   from   the  traditional   EE  umbrella:\n\n\n              • Servlet  API   (JSR 340)\n\n              • WebSocket     API  (JSR  356)\n\n              • Concurrency      Utilities (JSR  236)\n\n              • JSON   Binding    API  (JSR 367)\n\n              • Bean   Validation   (JSR  303)\n\n              • JPA  (JSR  338)\n\n              • JMS   (JSR 914)\n\n              • as well  as  JTA/JCA   setups  for  transaction    coordination,    if necessary.\n\n\n            The  Spring   Framework      also  supports    the Dependency       Injection   (JSR 330)  and   Common      Annotations\n            (JSR 250) specifications, which application developers may choose to use instead of the Spring-\n            specific  mechanisms      provided     by the  Spring   Framework.       Originally,  those   were   based   on  common\n            javax  packages.\n\n            As  of Spring   Framework       6.0, Spring   has  been   upgraded     to  the Jakarta   EE   9 level  (e.g. Servlet   5.0+,\n            JPA  3.0+), based    on  the  jakarta   namespace      instead   of the  traditional   javax   packages.    With   EE  9  as\n            the  minimum      and   EE  10  supported     already,   Spring   is prepared     to provide    out-of-the-box     support\n            for the further evolution of the Jakarta EE APIs. Spring Framework 6.0 is fully compatible with\n            Tomcat   10.1,  Jetty 11  and  Undertow     2.3  as web   servers,   and  also  with  Hibernate    ORM    6.1.\n\n\n            Over   time,  the role  of  Java/Jakarta    EE  in application    development      has  evolved.    In the  early  days   of\n            J2EE  and   Spring,  applications    were   created   to  be deployed     to an  application    server.  Today,   with  the\n            help  of Spring   Boot,   applications    are  created   in a  devops-   and   cloud-friendly     way,  with   the  Servlet\n            container   embedded      and   trivial  to change.   As  of  Spring   Framework      5, a  WebFlux     application    does\n            not  even   use  the  Servlet   API  directly   and   can  run   on  servers   (such   as  Netty)  that  are  not   Servlet\n            containers.\n\n\n            Spring  continues    to  innovate   and   to evolve.  Beyond     the Spring   Framework,      there  are  other   projects,\n            such as Spring Boot, Spring Security, Spring Data, Spring Cloud, Spring Batch, among others. It’s\n            important to remember that each project has its own source code repository, issue tracker, and\n            release  cadence.    See  spring.io/projects    for the  complete    list of Spring   projects.\n\n            1.3.    Design           Philosophy\n\n\n            When you learn about a framework, it’s important to know not only what it does but what\n            principles   it  follows. Here  are  the  guiding   principles   of the  Spring   Framework:\n\n\n              • Provide choice at every level. Spring lets you defer design decisions as late as possible. For\n                example, you can switch persistence providers through configuration without changing your\n                code.  The   same   is true  for  many   other   infrastructure     concerns    and  integration    with  third-party\n                APIs.\n\n              • Accommodate diverse perspectives. Spring embraces flexibility and is not opinionated about\n                how things should be done. It supports a wide range of application needs with different\n                perspectives.\n\n              • Maintain strong backward compatibility. Spring’s evolution has been carefully managed to\n                force  few   breaking    changes    between    versions.   Spring    supports   a  carefully   chosen   range   of  JDK\n                versions and third-party libraries to facilitate maintenance of applications and libraries that\n                depend    on  Spring.\n\n              • Care   about  API   design.  The  Spring   team   puts   a lot of thought   and   time  into  making    APIs  that  are\n                intuitive  and   that  hold  up  across  many    versions   and   many    years.\n\n              • Set high standards for code quality. The Spring Framework puts a strong emphasis on\n                meaningful,     current,   and   accurate    javadoc.   It is one   of very   few  projects   that  can   claim   clean\n                code   structure   with  no  circular   dependencies     between     packages.\n\n            1.4.    Feedback               and       Contributions\n\n\n            For how-to questions or diagnosing or debugging issues, we suggest using Stack Overflow. Click\n            here  for  a list of the  suggested    tags  to use  on  Stack   Overflow.    If  you’re fairly  certain   that there   is a\n            problem    in the  Spring   Framework      or would    like to suggest   a feature,   please  use  the  GitHub    Issues.\n\n            If you have a solution in mind or a suggested fix, you can submit a pull request on Github.\n            However,    please   keep   in mind    that, for  all but  the  most   trivial issues,  we  expect   a  ticket to  be  filed\n            in the issue  tracker,   where   discussions    take  place  and   leave  a record   for  future  reference.\n\n\n            For more    details  see the  guidelines    at the CONTRIBUTING,         top-level  project  page.\n\n            1.5.    Getting           Started\n\n\n            If  you are  just getting   started   with  Spring,   you  may    want   to begin   using   the  Spring   Framework      by\n            creating a Spring Boot-based application. Spring Boot provides a quick (and opinionated) way to\n            create a production-ready Spring-based application. It is based on the Spring Framework, favors\n            convention    over   configuration,    and  is designed    to get  you  up  and  running    as  quickly  as  possible.\n\n\n            You  can  use  start.spring.io    to generate    a basic  project   or follow   one  of  the  \"Getting   Started\"  guides,\n            such as Getting Started Building a RESTful Web Service. As well as being easier to digest, these\n            guides   are  very   task  focused,   and   most   of them    are  based   on   Spring   Boot.  They   also   cover   other\n            projects from the Spring portfolio that you might want to consider when solving a particular\n            problem.\n\n            Chapter                2.    Core           Technologies\n\n\n            This  part  of the  reference    documentation       covers   all  the  technologies   that  are  absolutely   integral   to\n            the Spring   Framework.\n\n\n            Foremost    amongst    these   is  the  Spring Framework’s      Inversion    of Control   (IoC)  container.   A  thorough\n            treatment    of the  Spring   Framework’s      IoC  container    is closely  followed    by  comprehensive       coverage\n            of Spring’s   Aspect-Oriented      Programming        (AOP)   technologies.    The   Spring   Framework       has  its own\n            AOP framework, which is conceptually easy to understand and which successfully addresses the\n            80%   sweet  spot  of AOP   requirements      in Java   enterprise   programming.\n\n\n            Coverage of Spring’s integration with AspectJ (currently the richest — in terms of features — and\n            certainly  most   mature    AOP   implementation       in the  Java  enterprise   space)   is also provided.\n\n\n            AOT processing can be used to optimize your application ahead-of-time. It is typically used for\n            native  image   deployment      using  GraalVM.\n\n            2.1.    The       IoC      Container\n\n\n            This  chapter   covers   Spring’s  Inversion    of Control   (IoC)  container.\n\n\n            2.1.1.   Introduction          to  the   Spring      IoC   Container        and    Beans\n\n            This chapter covers the Spring Framework implementation of the Inversion of Control (IoC)\n            principle. IoC is also known as dependency injection (DI). It is a process whereby objects define\n            their dependencies      (that  is, the other   objects   they  work   with)   only  through    constructor    arguments,\n            arguments to a factory method, or properties that are set on the object instance after it is\n            constructed or returned from a factory method. The container then injects those dependencies\n            when   it creates   the  bean.  This   process   is fundamentally      the  inverse   (hence   the  name,    Inversion    of\n            Control) of the bean itself controlling the instantiation or location of its dependencies by using\n            direct  construction    of classes  or  a mechanism      such   as the  Service  Locator    pattern.\n\n\n            The  org.springframework.beans         and   org.springframework.context         packages     are  the  basis  for  Spring\n            Framework’s       IoC   container.     The   BeanFactory      interface    provides     an   advanced      configuration\n            mechanism capable of managing any type of object. ApplicationContext is a sub-interface of\n            BeanFactory.   It adds:\n\n\n              • Easier   integration   with  Spring’s   AOP   features\n\n              • Message    resource    handling    (for use  in internationalization)\n\n              • Event   publication\n\n              • Application-layer       specific    contexts    such     as  the    WebApplicationContext         for   use   in   web\n                applications.\n\n\n            In short, the BeanFactory provides the configuration framework and basic functionality, and the\n            ApplicationContext       adds    more     enterprise-specific      functionality.     The    ApplicationContext        is  a\n            complete superset of the BeanFactory and is used exclusively in this chapter in descriptions of\n            Spring’s    IoC   container.     For    more     information      on    using    the   BeanFactory      instead    of   the\n\n            ApplicationContext,      see  the  section  covering    the BeanFactory    API.\n\n\n            In Spring, the objects that form the backbone of your application and that are managed by the\n            Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and\n            managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your\n            application.   Beans,   and   the dependencies      among     them,   are  reflected   in the  configuration    metadata\n            used  by  a container.\n\n\n            2.1.2.   Container        Overview\n\n            The  org.springframework.context.ApplicationContext                interface   represents    the  Spring   IoC  container\n            and  is responsible     for instantiating,    configuring,    and   assembling     the  beans.   The  container    gets  its\n            instructions on what objects to instantiate, configure, and assemble by reading configuration\n            metadata.    The  configuration     metadata     is  represented   in  XML,   Java  annotations,    or  Java  code.  It lets\n            you express the objects that compose your application and the rich interdependencies between\n            those  objects.\n\n\n            Several implementations of the ApplicationContext interface are supplied with Spring. In stand-\n            alone applications, it is common to create an instance of ClassPathXmlApplicationContext or\n            FileSystemXmlApplicationContext.           While     XML     has   been     the   traditional    format     for   defining\n            configuration metadata, you can instruct the container to use Java annotations or code as the\n            metadata    format   by  providing    a small   amount    of XML    configuration    to  declaratively   enable    support\n            for these  additional    metadata    formats.\n\n\n            In most application scenarios, explicit user code is not required to instantiate one or more\n            instances   of a  Spring   IoC  container.    For  example,    in a  web   application    scenario,   a simple   eight   (or\n            so) lines  of boilerplate    web   descriptor    XML    in the  web.xml    file of the  application    typically   suffices\n            (see Convenient     ApplicationContext       Instantiation    for Web    Applications).    If you  use  the  Spring   Tools\n            for Eclipse   (an  Eclipse-powered       development      environment),      you   can  easily  create   this  boilerplate\n            configuration    with   a few  mouse    clicks  or keystrokes.\n\n\n            The  following    diagram    shows    a high-level    view   of how   Spring    works.   Your   application    classes  are\n            combined with configuration metadata so that, after the ApplicationContext is created and\n            initialized,  you  have   a fully configured    and   executable    system   or  application.\n\n            Figure  1.  The  Spring IoC container\n\n\n            Configuration      Metadata\n\n            As the preceding diagram shows, the Spring IoC container consumes a form of configuration\n            metadata. This configuration metadata represents how you, as an application developer, tell the\n            Spring  container    to instantiate,   configure,   and   assemble    the  objects  in your   application.\n\n\n            Configuration metadata is traditionally supplied in a simple and intuitive XML format, which is\n            what   most  of  this chapter   uses  to convey    key  concepts    and  features   of the  Spring   IoC container.\n\n\n                              XML-based     metadata     is not  the  only  allowed    form   of configuration     metadata.     The\n                              Spring IoC container itself is totally decoupled from the format in which this\n                             configuration metadata is actually written. These days, many developers choose\n                              Java-based    configuration    for  their  Spring  applications.\n\n\n            For information     about   using   other  forms   of metadata     with  the  Spring   container,   see:\n\n\n              • Annotation-based         configuration:       Spring     2.5   introduced      support      for   annotation-based\n                configuration     metadata.\n\n              • Java-based configuration: Starting with Spring 3.0, many features provided by the Spring\n                JavaConfig project became part of the core Spring Framework. Thus, you can define beans\n                external to your application classes by using Java rather than XML files. To use these new\n                features,   see the  @Configuration,     @Bean,  @Import,  and   @DependsOn   annotations.\n\n            Spring   configuration     consists  of  at least  one   and  typically   more    than  one   bean   definition   that  the\n            container must manage. XML-based configuration metadata configures these beans as <bean/>\n            elements inside a top-level <beans/> element. Java configuration typically uses @Bean-annotated\n            methods    within   a @Configuration     class.\n\n            These   bean   definitions    correspond     to the  actual   objects   that  make   up   your   application.   Typically,\n            you define service layer objects, data access objects (DAOs), presentation objects such as Struts\n            Action instances, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so\n            forth. Typically,   one   does  not  configure    fine-grained     domain    objects   in the  container,    because    it  is\n\n            usually   the responsibility    of  DAOs   and   business    logic  to create  and   load  domain     objects.  However,\n            you  can   use  Spring’s   integration    with  AspectJ    to configure    objects   that  have   been   created   outside\n            the control   of an  IoC  container.   See  Using   AspectJ   to dependency-inject      domain     objects  with  Spring.\n\n\n            The  following   example     shows   the  basic  structure   of XML-based      configuration     metadata:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"...\"    class=\"...\">      ①   ②\n                         <!--   collaborators      and   configuration      for   this   bean  go   here  -->\n                    </bean>\n\n\n                    <bean   id=\"...\"    class=\"...\">\n                         <!--   collaborators      and   configuration      for   this   bean  go   here  -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      go  here   -->\n\n\n              </beans>\n\n\n            ① The    id attribute   is a string  that identifies   the individual    bean   definition.\n\n            ② The    class  attribute   defines   the type  of the  bean   and  uses   the fully  qualified   classname.\n\n            The  value   of the  id attribute   refers   to collaborating    objects.  The   XML    for referring   to  collaborating\n            objects  is not shown    in  this example.    See  Dependencies      for more    information.\n\n\n            Instantiating    a  Container\n\n            The  location   path   or paths   supplied    to an  ApplicationContext       constructor    are  resource    strings  that\n            let  the  container  load  configuration     metadata    from   a variety   of external   resources,    such  as  the local\n            file  system, the  Java  CLASSPATH,   and   so on.\n\n\n            Java\n\n\n              ApplicationContext        context    =  new   ClassPathXmlApplicationContext(\"services.xml\",\n              \"daos.xml\");\n\n\n\n            Kotlin\n\n\n              val   context    =  ClassPathXmlApplicationContext(\"services.xml\",                  \"daos.xml\")\n\n                              After  you  learn   about   Spring’s   IoC  container,    you   may   want   to  know   more    about\n                              Spring’s   Resource     abstraction     (as  described     in  Resources),     which     provides     a\n                             convenient mechanism for reading an InputStream from locations defined in a\n                              URI syntax. In particular, Resource paths are used to construct applications\n                              contexts,  as  described    in Application    Contexts   and   Resource    Paths.\n\n\n            The  following   example     shows   the  service   layer  objects  (services.xml)     configuration     file:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <!--   services    -->\n\n\n                    <bean   id=\"petStore\"\n              class=\"org.springframework.samples.jpetstore.services.PetStoreServiceImpl\">\n                         <property     name=\"accountDao\"        ref=\"accountDao\"/>\n                         <property     name=\"itemDao\"       ref=\"itemDao\"/>\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      for  services     go  here   -->\n\n\n              </beans>\n\n\n\n            The  following   example     shows   the  data  access   objects  daos.xml   file:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"accountDao\"\n                         class=\"org.springframework.samples.jpetstore.dao.jpa.JpaAccountDao\">\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <bean   id=\"itemDao\"\n              class=\"org.springframework.samples.jpetstore.dao.jpa.JpaItemDao\">\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      for  data   access    objects    go  here   -->\n\n\n              </beans>\n\n            In the  preceding    example,     the  service  layer   consists  of  the  PetStoreServiceImpl       class and   two   data\n            access objects of the types JpaAccountDao and JpaItemDao (based on the JPA Object-Relational\n            Mapping    standard).    The  property    name  element    refers  to the  name   of  the JavaBean     property,   and  the\n            ref element refers to the name of another bean definition. This linkage between id and ref\n            elements expresses the dependency between collaborating objects. For details of configuring an\n            object’s  dependencies,     see  Dependencies.\n\n\n\n            Composing    XML-based    Configuration   Metadata\n\n            It can be useful to have bean definitions span multiple XML files. Often, each individual XML\n            configuration    file represents    a logical  layer  or module     in your  architecture.\n\n\n            You can use the application context constructor to load bean definitions from all these XML\n            fragments.    This  constructor    takes  multiple   Resource   locations,   as was   shown    in the  previous    section.\n            Alternatively,   use  one   or more    occurrences     of the  <import/>    element    to load   bean   definitions   from\n            another   file or files. The  following    example    shows    how   to do  so:\n\n\n\n              <beans>\n                    <import    resource=\"services.xml\"/>\n                    <import    resource=\"resources/messageSource.xml\"/>\n                    <import    resource=\"/resources/themeSource.xml\"/>\n\n\n                    <bean   id=\"bean1\"     class=\"...\"/>\n                    <bean   id=\"bean2\"     class=\"...\"/>\n              </beans>\n\n\n\n            In the preceding example, external bean definitions are loaded from three files: services.xml,\n            messageSource.xml,      and  themeSource.xml.      All location   paths   are   relative  to  the  definition   file doing\n            the importing,    so  services.xml    must    be in  the same    directory   or  classpath   location   as  the file doing\n            the importing,     while  messageSource.xml       and  themeSource.xml      must   be  in  a resources    location   below\n            the  location   of the  importing     file.  As  you can  see,  a leading    slash  is ignored.   However,     given   that\n            these  paths   are  relative,  it is better  form   not  to  use  the  slash  at all. The  contents    of the  files being\n            imported,    including   the  top  level  <beans/>   element,    must   be  valid  XML    bean   definitions,   according\n            to the Spring   Schema.\n\n                              It  is  possible,  but  not  recommended,     to reference    files in parent   directories   using   a\n                              relative \"../\" path. Doing so creates a dependency on a file that is outside the\n                              current    application.     In   particular,    this   reference     is  not   recommended          for\n                              classpath: URLs (for example, classpath:../services.xml), where the runtime\n                              resolution process chooses the “nearest” classpath root and then looks into its\n                              parent directory. Classpath configuration changes may lead to the choice of a\n                              different,  incorrect   directory.\n                \n                              You  can  always    use  fully qualified    resource   locations   instead   of  relative  paths:   for\n                              example,        file:C:/config/services.xml             or     classpath:/config/services.xml.\n                              However, be aware that you are coupling your application’s configuration to\n                              specific  absolute   locations.   It  is  generally  preferable  to keep   an indirection    for such\n                              absolute locations — for example, through \"${…}\" placeholders that are resolved\n                              against  JVM   system   properties    at runtime.\n\n\n            The  namespace      itself provides    the  import   directive   feature.  Further    configuration     features   beyond\n            plain bean definitions are available in a selection of XML namespaces provided by Spring — for\n            example,    the context   and   util  namespaces.\n\n\n\n            The Groovy   Bean   Definition  DSL\n\n            As a further example for externalized configuration metadata, bean definitions can also be\n            expressed    in Spring’s   Groovy    Bean   Definition    DSL,  as known     from   the  Grails  framework.     Typically,\n            such  configuration     live in a \".groovy\"    file  with the structure   shown    in  the following    example:\n\n\n\n              beans    {\n                    dataSource(BasicDataSource)           {\n                         driverClassName       =  \"org.hsqldb.jdbcDriver\"\n                         url   =  \"jdbc:hsqldb:mem:grailsDB\"\n                         username     = \"sa\"\n                         password     = \"\"\n                         settings     = [mynew:\"setting\"]\n                    }\n                    sessionFactory(SessionFactory)            {\n                         dataSource     =  dataSource\n                    }\n                    myService(MyService)         {\n                         nestedBean     =  {  AnotherBean     bean   ->\n                               dataSource     =  dataSource\n                         }\n                    }\n              }\n\n\n\n            This  configuration     style  is largely  equivalent     to XML    bean   definitions    and  even   supports    Spring’s\n            XML   configuration     namespaces.      It also  allows   for importing     XML    bean   definition   files through    an\n            importBeans    directive.\n\n            Using   the  Container\n\n            The  ApplicationContext      is the  interface   for an  advanced     factory  capable    of maintaining     a registry   of\n            different beans and their dependencies. By using the method T getBean(String name, Class<T>\n            requiredType),    you  can  retrieve   instances   of  your  beans.\n\n            The  ApplicationContext       lets you   read   bean   definitions   and   access   them,   as  the  following    example\n            shows:\n\n\n            Java\n\n\n              //  create    and   configure    beans\n              ApplicationContext        context    =  new   ClassPathXmlApplicationContext(\"services.xml\",\n              \"daos.xml\");\n\n\n              //  retrieve     configured     instance\n              PetStoreService       service    =  context.getBean(\"petStore\",            PetStoreService.class);\n\n\n              //  use   configured     instance\n              List<String>      userList     = service.getUsernameList();\n\n\n\n            Kotlin\n\n\n              import    org.springframework.beans.factory.getBean\n\n\n              //  create    and   configure    beans\n              val   context    =  ClassPathXmlApplicationContext(\"services.xml\",                  \"daos.xml\")\n\n\n              //  retrieve     configured     instance\n              val   service    =  context.getBean<PetStoreService>(\"petStore\")\n\n\n              //  use   configured     instance\n              var   userList    =  service.getUsernameList()\n\n\n\n            With    Groovy     configuration,      bootstrapping       looks    very    similar.   It  has    a   different    context\n            implementation class which is Groovy-aware (but also understands XML bean definitions). The\n            following   example    shows    Groovy    configuration:\n\n\n            Java\n\n\n              ApplicationContext        context    =  new   GenericGroovyApplicationContext(\"services.groovy\",\n              \"daos.groovy\");\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericGroovyApplicationContext(\"services.groovy\",                    \"daos.groovy\")\n\n\n\n            The  most   flexible  variant   is GenericApplicationContext         in  combination     with   reader   delegates — for\n            example,    with  XmlBeanDefinitionReader        for XML    files,  as  the  following example    shows:\n\n            Java\n\n\n              GenericApplicationContext           context    =  new  GenericApplicationContext();\n              new   XmlBeanDefinitionReader(context).loadBeanDefinitions(\"services.xml\",                           \"daos.xml\");\n              context.refresh();\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericApplicationContext()\n              XmlBeanDefinitionReader(context).loadBeanDefinitions(\"services.xml\",                           \"daos.xml\")\n              context.refresh()\n\n\n\n            You  can  also  use  the GroovyBeanDefinitionReader         for Groovy    files, as the  following   example     shows:\n\n\n            Java\n\n\n              GenericApplicationContext           context    =  new  GenericApplicationContext();\n              new   GroovyBeanDefinitionReader(context).loadBeanDefinitions(\"services.groovy\",\n              \"daos.groovy\");\n              context.refresh();\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericApplicationContext()\n              GroovyBeanDefinitionReader(context).loadBeanDefinitions(\"services.groovy\",\n              \"daos.groovy\")\n              context.refresh()\n\n\n\n            You can mix and match such reader delegates on the same ApplicationContext, reading bean\n            definitions   from   diverse  configuration     sources.\n\n\n            You  can  then  use  getBean   to retrieve   instances    of your  beans.   The  ApplicationContext       interface   has  a\n            few  other   methods    for  retrieving   beans,   but,  ideally, your   application    code   should   never   use  them.\n            Indeed,   your  application    code   should   have   no  calls to  the getBean()    method    at  all  and thus  have   no\n            dependency      on Spring   APIs   at all.  For  example,  Spring’s   integration    with  web   frameworks      provides\n            dependency     injection   for  various   web   framework     components      such   as controllers    and  JSF-managed\n            beans, letting you declare a dependency on a specific bean through metadata (such as an\n            autowiring    annotation).\n\n\n            2.1.3.   Bean     Overview\n\n            A Spring   IoC  container    manages    one   or more    beans.  These   beans   are  created   with   the configuration\n            metadata    that  you  supply   to the  container    (for example,    in the  form   of XML   <bean/>   definitions).\n\n\n            Within   the  container    itself,  these bean   definitions   are  represented     as BeanDefinition     objects,   which\n            contain   (among    other  information)     the  following   metadata:\n\n              • A package-qualified class name: typically, the actual implementation class of the bean being\n\n                defined.\n\n              • Bean behavioral configuration elements, which state how the bean should behave in the\n                container    (scope,  lifecycle  callbacks,   and  so  forth).\n\n              • References     to other  beans   that  are  needed    for the  bean   to do  its work.  These   references    are  also\n                called  collaborators    or  dependencies.\n\n              • Other   configuration     settings   to set  in the  newly    created   object — for    example,    the  size  limit  of\n                the  pool  or the  number     of connections     to use  in a bean   that  manages    a  connection    pool.\n\n\n            This metadata translates to a set of properties that make up each bean definition. The following\n            table describes    these  properties:\n\n\n            Table 1. The  bean  definition\n\n            Property                                                       Explained     in…\n\n            Class                                                          Instantiating   Beans\n\n            Name                                                           Naming    Beans\n\n            Scope                                                          Bean   Scopes\n\n            Constructor     arguments                                      Dependency      Injection\n\n            Properties                                                     Dependency      Injection\n\n            Autowiring     mode                                            Autowiring     Collaborators\n\n            Lazy   initialization   mode                                   Lazy-initialized    Beans\n\n            Initialization   method                                        Initialization   Callbacks\n\n            Destruction     method                                         Destruction    Callbacks\n\n\n            In addition to bean definitions that contain information on how to create a specific bean, the\n            ApplicationContext      implementations       also  permit   the  registration   of existing   objects  that  are  created\n            outside the container (by users). This is done by accessing the ApplicationContext’s BeanFactory\n            through      the     getBeanFactory()        method,       which      returns      the    DefaultListableBeanFactory\n            implementation.          DefaultListableBeanFactory            supports       this     registration       through       the\n            registerSingleton(..)        and    registerBeanDefinition(..)          methods.     However,      typical   applications\n            work   solely  with  beans   defined   through    regular   bean   definition   metadata.\n\n\n                              Bean   metadata    and   manually    supplied    singleton   instances   need   to be  registered    as\n                              early  as possible,   in order   for  the container    to properly    reason    about   them   during\n                              autowiring    and   other  introspection     steps.  While   overriding    existing   metadata    and\n                             existing  singleton    instances    is supported    to  some    degree,   the  registration   of  new\n                              beans at runtime (concurrently with live access to the factory) is not officially\n                              supported    and   may   lead  to  concurrent    access   exceptions,    inconsistent    state  in the\n                              bean  container,    or both.\n\n\n\n            Naming     Beans\n\n            Every   bean   has  one  or  more   identifiers.  These   identifiers   must   be  unique    within   the container    that\n            hosts  the  bean.   A bean   usually   has   only  one   identifier.  However,     if it  requires  more   than   one,  the\n\n            extra  ones  can  be  considered     aliases.\n\n\n            In XML-based      configuration    metadata,    you   use  the  id attribute,  the  name  attribute,  or  both  to specify\n            the  bean   identifiers.  The   id  attribute   lets you   specify  exactly   one   id. Conventionally,     these   names\n            are  alphanumeric      ('myBean',    'someService',    etc.), but  they  can  contain    special  characters    as  well. If\n            you  want    to introduce    other   aliases  for  the  bean,   you  can   also  specify  them    in the  name   attribute,\n            separated    by  a comma     (,), semicolon     (;), or white   space.   As  a historical   note,  in  versions   prior   to\n            Spring   3.1,  the  id  attribute  was defined   as  an xsd:ID   type,  which   constrained     possible   characters.   As\n            of 3.1, it is defined as an xsd:string type. Note that bean id uniqueness is still enforced by the\n            container,   though   no  longer   by  XML   parsers.\n\n\n            You  are  not  required   to supply    a name  or an  id for  a bean.   If  you do not  supply   a  name  or id explicitly,\n            the container    generates    a unique    name    for that  bean.  However,     if you  want   to refer  to  that bean   by\n            name, through the use of the ref element or a Service Locator style lookup, you must provide a\n            name. Motivations for not supplying a name are related to using inner beans and autowiring\n            collaborators.\n\n\n                                                    Bean     Naming        Conventions\n\n               The   convention     is  to  use  the  standard Java  convention     for  instance   field names    when    naming\n               beans. That is, bean names start with a lowercase letter and are camel-cased from there.\n               Examples     of such   names    include   accountManager,    accountService,     userDao,   loginController,     and\n               so  forth.\n\n\n               Naming     beans   consistently    makes    your   configuration     easier  to read   and   understand.     Also,  if\n               you   use  Spring  AOP,   it  helps a lot when   applying    advice   to a set of beans    related  by  name.\n\n\n\n\n                              With component scanning in the classpath, Spring generates bean names for\n                              unnamed     components,      following    the rules  described    earlier:  essentially,   taking  the\n                              simple   class  name    and  turning    its  initial  character  to lower-case.    However,     in the\n                             (unusual)    special  case   when    there  is more    than   one   character    and  both   the  first\n                              and  second   characters    are  upper   case,  the  original  casing   gets preserved.    These   are\n                              the same    rules  as  defined   by  java.beans.Introspector.decapitalize            (which    Spring\n                              uses  here).\n\n\n\n            Aliasing a Bean   outside  the Bean  Definition\n\n            In a bean definition itself, you can supply more than one name for the bean, by using a\n            combination     of up  to  one  name    specified   by  the id  attribute  and   any  number     of other   names    in the\n            name attribute. These names can be equivalent aliases to the same bean and are useful for some\n            situations, such as letting each component in an application refer to a common dependency by\n            using  a bean   name    that is specific  to that  component      itself.\n\n            Specifying all aliases where the bean is actually defined is not always adequate, however. It is\n            sometimes     desirable   to  introduce    an  alias  for a  bean   that  is defined   elsewhere.     This  is commonly\n            the case in large systems where configuration is split amongst each subsystem, with each\n            subsystem     having   its own   set  of object   definitions.   In XML-based      configuration     metadata,    you   can\n            use the  <alias/>   element    to accomplish     this. The  following    example    shows    how   to do  so:\n\n              <alias    name=\"fromName\"       alias=\"toName\"/>\n\n\n\n            In this case, a bean (in the same container) named fromName may also, after the use of this alias\n            definition,  be  referred   to as  toName.\n\n\n            For example,     the configuration     metadata    for  subsystem     A may   refer  to a  DataSource     by the  name    of\n            subsystemA-dataSource.       The  configuration     metadata     for  subsystem     B  may   refer  to a  DataSource     by\n            the name of subsystemB-dataSource. When composing the main application that uses both these\n            subsystems,    the  main   application    refers  to the  DataSource     by  the name    of myApp-dataSource.     To  have\n            all three names refer to the same object, you can add the following alias definitions to the\n            configuration    metadata:\n\n\n\n              <alias    name=\"myApp-dataSource\"          alias=\"subsystemA-dataSource\"/>\n              <alias    name=\"myApp-dataSource\"          alias=\"subsystemB-dataSource\"/>\n\n\n\n            Now   each   component      and  the  main   application    can   refer  to the  dataSource    through    a  name   that  is\n            unique   and   guaranteed      not  to clash   with  any   other   definition   (effectively   creating   a  namespace),\n            yet they  refer  to the  same   bean.\n\n\n                                                           Java-configuration\n\n               If you   use  Javaconfiguration,      the  @Bean  annotation     can   be used   to  provide   aliases.  See   Using\n               the  @Bean  Annotation     for details.\n\n\n\n\n            Instantiating    Beans\n\n            A bean   definition   is essentially   a recipe   for creating   one   or more   objects.   The  container    looks  at the\n            recipe for a named bean when asked and uses the configuration metadata encapsulated by that\n            bean  definition   to  create  (or acquire)   an  actual   object.\n\n\n            If  you use  XML-based      configuration     metadata,    you  specify   the  type  (or  class) of  object  that  is to be\n            instantiated   in  the class  attribute   of the  <bean/>   element.    This  class  attribute   (which,   internally,  is a\n            Class   property      on   a   BeanDefinition      instance)     is  usually    mandatory.       (For   exceptions,     see\n            Instantiation    by  Using   an  Instance   Factory    Method    and   Bean   Definition    Inheritance.)    You   can  use\n            the Class  property    in one   of two  ways:\n\n\n              • Typically, to specify the bean class to be constructed in the case where the container itself\n                directly creates the bean by calling its constructor reflectively, somewhat equivalent to Java\n                code   with  the  new operator.\n\n              • To specify the actual class containing the static factory method that is invoked to create the\n                object,  in the  less common      case  where    the  container    invokes   a static   factory   method    on  a class\n                to create   the  bean.   The  object   type  returned    from    the invocation     of the  static   factory   method\n                may   be  the same    class or  another   class  entirely.\n\n                                                          Nested      class    names\n\n               If you   want   to configure    a  bean   definition   for  a nested   class,  you  may    use  either  the  binary\n               name    or the  source   name    of the  nested   class.\n\n\n               For example, if you have a class called SomeThing in the com.example package, and this\n               SomeThing    class  has  a static   nested   class  called  OtherThing,    they  can   be  separated    by  a dollar\n               sign ($) or a dot (.). So the value of the class attribute in a bean definition would be\n               com.example.SomeThing$OtherThing           or com.example.SomeThing.OtherThing.\n\n\n\n\n\n            Instantiation  with  a Constructor\n\n            When you create a bean by the constructor approach, all normal classes are usable by and\n            compatible    with   Spring.  That   is,  the  class  being developed    does   not  need   to implement     any   specific\n            interfaces or to be coded in a specific fashion. Simply specifying the bean class should suffice.\n            However,     depending     on  what    type  of  IoC  you  use   for that  specific   bean,   you  may    need   a default\n            (empty)   constructor.\n\n\n            The  Spring   IoC  container    can  manage     virtually   any  class  you  want   it to manage.     It  is  not  limited  to\n            managing true JavaBeans. Most Spring users prefer actual JavaBeans with only a default (no-\n            argument) constructor and appropriate setters and getters modeled after the properties in the\n            container.   You   can  also  have   more   exotic  non-bean-style      classes  in  your  container.    If,  for  example,\n            you need to use a legacy connection pool that absolutely does not adhere to the JavaBean\n            specification,   Spring   can  manage    it as well.\n\n\n            With  XML-based      configuration     metadata    you  can   specify  your   bean   class as follows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\"/>\n\n\n              <bean    name=\"anotherExample\"         class=\"examples.ExampleBeanTwo\"/>\n\n\n\n            For details about the mechanism for supplying arguments to the constructor (if required) and\n            setting  object  instance   properties    after the  object  is constructed,    see  Injecting  Dependencies.\n\n\n\n            Instantiation  with  a Static Factory  Method\n\n            When    defining   a bean   that  you  create  with   a static factory   method,    use  the class   attribute  to specify\n            the class  that  contains   the  static   factory   method    and   an  attribute   named    factory-method     to specify\n            the name of the factory method itself. You should be able to call this method (with optional\n            arguments,     as described    later)  and   return   a live  object,  which    subsequently     is treated   as  if it had\n            been  created    through    a constructor.    One   use  for such   a bean   definition   is to call static   factories   in\n            legacy  code.\n\n\n            The  following    bean   definition   specifies   that  the  bean   will  be  created   by  calling   a factory   method.\n            The definition does not specify the type (class) of the returned object, but rather the class\n            containing the factory method. In this example, the createInstance() method must be a static\n            method.   The   following   example     shows   how   to specify   a factory   method:\n\n              <bean    id=\"clientService\"\n                    class=\"examples.ClientService\"\n                    factory-method=\"createInstance\"/>\n\n\n\n            The  following   example     shows   a class  that  would   work    with  the  preceding    bean   definition:\n\n\n            Java\n\n\n              public    class   ClientService      {\n                    private    static   ClientService       clientService      =  new  ClientService();\n                    private    ClientService()       {}\n\n\n                    public   static    ClientService      createInstance()        {\n                         return    clientService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ClientService      private    constructor()      {\n                    companion     object   {\n                         private    val   clientService      =  ClientService()\n                         @JvmStatic\n                         fun   createInstance()       =  clientService\n                    }\n              }\n\n\n\n            For details about the mechanism for supplying (optional) arguments to the factory method and\n            setting  object   instance   properties    after  the  object   is returned    from   the  factory,   see  Dependencies\n            and  Configuration     in Detail.\n\n\n\n            Instantiation  by Using  an  Instance  Factory  Method\n\n            Similar to instantiation through a static factory method, instantiation with an instance factory\n            method    invokes    a non-static   method     of an  existing   bean   from   the  container    to create   a new   bean.\n            To  use  this mechanism,      leave   the  class   attribute  empty    and,   in the  factory-bean     attribute,  specify\n            the name of a bean in the current (or parent or ancestor) container that contains the instance\n            method    that  is  to  be  invoked to  create  the  object.  Set the  name    of the  factory   method    itself with  the\n            factory-method     attribute.  The  following    example    shows    how   to configure    such  a bean:\n\n              <!--   the   factory    bean,   which   contains     a method    called    createInstance()       -->\n              <bean    id=\"serviceLocator\"        class=\"examples.DefaultServiceLocator\">\n                    <!--   inject   any   dependencies      required    by  this   locator    bean   -->\n              </bean>\n\n\n              <!--   the   bean   to  be  created    via  the   factory    bean   -->\n              <bean    id=\"clientService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createClientServiceInstance\"/>\n\n\n\n            The  following   example     shows   the  corresponding      class:\n\n\n            Java\n\n\n              public    class   DefaultServiceLocator         {\n\n\n                    private    static   ClientService       clientService      =  new  ClientServiceImpl();\n\n\n                    public   ClientService       createClientServiceInstance()            {\n                         return    clientService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    DefaultServiceLocator         {\n                    companion     object   {\n                         private    val   clientService      =  ClientServiceImpl()\n                    }\n                    fun  createClientServiceInstance():             ClientService      {\n                         return    clientService\n                    }\n              }\n\n\n\n            One  factory   class can   also hold   more   than  one   factory  method,    as the  following    example    shows:\n\n\n\n              <bean    id=\"serviceLocator\"        class=\"examples.DefaultServiceLocator\">\n                    <!--   inject   any   dependencies      required    by  this   locator    bean   -->\n              </bean>\n\n\n              <bean    id=\"clientService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createClientServiceInstance\"/>\n\n\n              <bean    id=\"accountService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createAccountServiceInstance\"/>\n\n            The  following   example     shows   the  corresponding      class:\n\n\n            Java\n\n\n              public    class   DefaultServiceLocator         {\n\n\n                    private    static   ClientService       clientService      =  new  ClientServiceImpl();\n\n\n                    private    static   AccountService       accountService       = new   AccountServiceImpl();\n\n\n                    public   ClientService       createClientServiceInstance()            {\n                         return    clientService;\n                    }\n\n\n                    public   AccountService       createAccountServiceInstance()             {\n                         return    accountService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    DefaultServiceLocator         {\n                    companion     object   {\n                         private    val   clientService      =  ClientServiceImpl()\n                         private    val   accountService      =  AccountServiceImpl()\n                    }\n\n\n                    fun  createClientServiceInstance():             ClientService      {\n                         return    clientService\n                    }\n\n\n                    fun  createAccountServiceInstance():             AccountService       {\n                         return    accountService\n                    }\n              }\n\n\n\n            This approach shows that the factory bean itself can be managed and configured through\n            dependency     injection   (DI). See  Dependencies      and   Configuration     in Detail.\n\n\n                              In Spring   documentation,       \"factory   bean\"   refers  to a  bean   that is configured     in the\n                              Spring container and that creates objects through an instance or static factory\n                             method. By contrast, FactoryBean (notice the capitalization) refers to a Spring-\n                              specific  FactoryBean    implementation       class.\n\n\n\n            Determining    a Bean’s Runtime    Type\n\n            The runtime type of a specific bean is non-trivial to determine. A specified class in the bean\n            metadata    definition   is just  an  initial class  reference,    potentially   combined      with  a  declared   factory\n            method    or being   a  FactoryBean    class which    may   lead  to  a different   runtime    type  of the  bean,   or not\n\n            being set at all in case of an instance-level factory method (which is resolved via the specified\n            factory-bean name instead). Additionally, AOP proxying may wrap a bean instance with an\n            interface-based     proxy   with   limited  exposure     of the  target   bean’s  actual   type  (just  its implemented\n            interfaces).\n\n            The recommended way to find out about the actual runtime type of a particular bean is a\n            BeanFactory.getType      call  for the  specified   bean   name.   This   takes  all of the  above   cases   into account\n            and  returns   the  type   of object   that a  BeanFactory.getBean       call is going   to return   for  the  same   bean\n            name.\n\n            2.1.4.   Dependencies\n\n            A typical  enterprise    application    does   not  consist  of a  single  object  (or  bean   in the  Spring   parlance).\n            Even   the  simplest   application    has   a few   objects   that  work   together    to present    what   the  end-user\n            sees  as a  coherent    application.    This  next  section   explains    how   you   go  from   defining   a  number     of\n            bean  definitions    that stand   alone  to  a fully realized   application    where   objects   collaborate    to achieve\n            a goal.\n\n\n            Dependency       Injection\n\n            Dependency      injection   (DI) is a process   whereby     objects  define   their  dependencies      (that is, the  other\n            objects  with  which    they  work)   only  through    constructor    arguments,     arguments     to a factory   method,\n            or properties    that  are  set  on  the  object  instance    after  it  is  constructed  or  returned    from   a factory\n            method. The container then injects those dependencies when it creates the bean. This process is\n            fundamentally      the  inverse   (hence   the  name,   Inversion    of  Control)   of the  bean   itself controlling   the\n            instantiation   or  location  of  its  dependencies    on  its own   by  using  direct  construction    of  classes  or the\n            Service  Locator    pattern.\n\n\n            Code   is cleaner   with  the  DI  principle,   and   decoupling    is more    effective  when    objects   are  provided\n            with their dependencies. The object does not look up its dependencies and does not know the\n            location   or class  of  the  dependencies.      As  a result,  your   classes   become    easier   to test, particularly\n            when the dependencies are on interfaces or abstract base classes, which allow for stub or mock\n            implementations       to be used   in unit  tests.\n\n\n            DI  exists   in   two    major    variants:    Constructor-based        dependency       injection    and    Setter-based\n            dependency     injection.\n\n\n\n            Constructor-based    Dependency     Injection\n\n            Constructor-based DI is accomplished by the container invoking a constructor with a number of\n            arguments,      each   representing      a  dependency.       Calling   a   static   factory    method     with    specific\n            arguments to construct the bean is nearly equivalent, and this discussion treats arguments to a\n            constructor    and  to  a static   factory  method     similarly.  The  following    example    shows    a class  that  can\n            only  be dependency-injected        with  constructor     injection:\n\n            Java\n\n\n              public    class   SimpleMovieLister        {\n\n\n                    //  the  SimpleMovieLister        has   a dependency      on  a MovieFinder\n                    private    final   MovieFinder      movieFinder;\n\n\n                    //  a  constructor     so  that   the   Spring   container     can   inject   a  MovieFinder\n                    public   SimpleMovieLister(MovieFinder             movieFinder)      {\n                         this.movieFinder        = movieFinder;\n                    }\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Kotlin\n\n\n              //  a  constructor      so  that   the  Spring    container     can  inject    a MovieFinder\n              class    SimpleMovieLister(private          val   movieFinder:      MovieFinder)      {\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Notice that there is nothing special about this class. It is a POJO that has no dependencies on\n            container   specific  interfaces,   base   classes, or  annotations.\n\n\n            Constructor     Argument      Resolution\n\n            Constructor argument resolution matching occurs by using the argument’s type. If no potential\n            ambiguity exists in the constructor arguments of a bean definition, the order in which the\n            constructor    arguments     are  defined    in a bean   definition    is the order   in  which   those   arguments     are\n            supplied   to the  appropriate     constructor    when   the  bean   is being   instantiated.   Consider    the following\n            class:\n\n\n            Java\n\n\n              package    x.y;\n\n\n              public    class   ThingOne     {\n\n\n                    public   ThingOne(ThingTwo        thingTwo,     ThingThree     thingThree)      {\n                         //  ...\n                    }\n              }\n\n            Kotlin\n\n\n              package    x.y\n\n\n              class    ThingOne(thingTwo:        ThingTwo,    thingThree:      ThingThree)\n\n\n\n            Assuming that the ThingTwo and ThingThree classes are not related by inheritance, no potential\n            ambiguity    exists.  Thus,  the  following    configuration     works    fine, and   you  do  not  need   to  specify  the\n            constructor    argument     indexes   or types   explicitly  in the  <constructor-arg/>      element.\n\n\n\n              <beans>\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\">\n                         <constructor-arg        ref=\"beanTwo\"/>\n                         <constructor-arg        ref=\"beanThree\"/>\n                    </bean>\n\n\n                    <bean   id=\"beanTwo\"      class=\"x.y.ThingTwo\"/>\n\n\n                    <bean   id=\"beanThree\"       class=\"x.y.ThingThree\"/>\n              </beans>\n\n\n\n            When    another   bean   is referenced,    the  type  is known,    and  matching     can  occur   (as was   the case   with\n            the preceding example). When a simple type is used, such as <value>true</value>, Spring cannot\n            determine    the  type  of  the  value,  and  so  cannot   match    by  type  without    help.  Consider    the following\n            class:\n\n\n            Java\n\n\n              package    examples;\n\n\n              public    class   ExampleBean      {\n\n\n                    //  Number    of  years   to  calculate     the  Ultimate     Answer\n                    private    final   int   years;\n\n\n                    //  The  Answer    to  Life,   the   Universe,     and  Everything\n                    private    final   String    ultimateAnswer;\n\n\n                    public   ExampleBean(int       years,    String    ultimateAnswer)       {\n                         this.years     =  years;\n                         this.ultimateAnswer         =  ultimateAnswer;\n                    }\n              }\n\n            Kotlin\n\n\n              package    examples\n\n\n              class    ExampleBean(\n                    private    val  years:    Int,   //  Number    of  years   to  calculate     the  Ultimate     Answer\n                    private    val  ultimateAnswer:       String    //  The   Answer   to  Life,    the  Universe,     and\n              Everything\n              )\n\n\n\n            Constructor   argument    type  matching\n            In the  preceding    scenario,    the  container    can  use  type  matching     with   simple   types  if you   explicitly\n            specify  the  type  of  the  constructor    argument     by  using   the  type  attribute,  as  the  following    example\n            shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       type=\"int\"     value=\"7500000\"/>\n                    <constructor-arg       type=\"java.lang.String\"          value=\"42\"/>\n              </bean>\n\n\n\n            Constructor   argument    index\n            You can use the index attribute to specify explicitly the index of constructor arguments, as the\n            following   example    shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       index=\"0\"     value=\"7500000\"/>\n                    <constructor-arg       index=\"1\"     value=\"42\"/>\n              </bean>\n\n\n\n            In addition to resolving the ambiguity of multiple simple values, specifying an index resolves\n            ambiguity    where    a constructor    has  two  arguments     of  the same    type.\n\n                             The  index   is  0-based.\n\n\n            Constructor   argument    name\n            You can also use the constructor parameter name for value disambiguation, as the following\n            example    shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       name=\"years\"      value=\"7500000\"/>\n                    <constructor-arg       name=\"ultimateAnswer\"         value=\"42\"/>\n              </bean>\n\n\n\n            Keep   in mind    that, to  make   this  work   out  of  the  box,  your   code  must    be  compiled    with   the  debug\n            flag enabled    so that  Spring   can  look   up  the parameter     name    from   the  constructor.    If you  cannot    or\n\n            do not  want   to  compile   your   code   with  the  debug   flag, you   can  use  the  @ConstructorProperties         JDK\n            annotation to explicitly name your constructor arguments. The sample class would then have to\n            look  as follows:\n\n\n            Java\n\n\n              package    examples;\n\n\n              public    class   ExampleBean      {\n\n\n                    //  Fields    omitted\n\n\n                    @ConstructorProperties({\"years\",             \"ultimateAnswer\"})\n                    public   ExampleBean(int       years,    String    ultimateAnswer)       {\n                         this.years     =  years;\n                         this.ultimateAnswer         =  ultimateAnswer;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              package    examples\n\n\n              class    ExampleBean\n              @ConstructorProperties(\"years\",             \"ultimateAnswer\")\n              constructor(val       years:    Int,   val  ultimateAnswer:       String)\n\n\n\n\n            Setter-based  Dependency     Injection\n\n            Setter-based DI is accomplished by the container calling setter methods on your beans after\n            invoking a no-argument constructor or a no-argument static factory method to instantiate your\n            bean.\n\n            The following example shows a class that can only be dependency-injected by using pure setter\n            injection.  This  class  is  conventional   Java.  It is  a  POJO that has  no  dependencies      on  container    specific\n            interfaces,  base   classes,  or annotations.\n\n            Java\n\n\n              public    class   SimpleMovieLister        {\n\n\n                    //  the  SimpleMovieLister        has   a dependency      on  the  MovieFinder\n                    private    MovieFinder     movieFinder;\n\n\n                    //  a  setter   method    so  that   the  Spring    container     can  inject    a  MovieFinder\n                    public   void   setMovieFinder(MovieFinder           movieFinder)      {\n                         this.movieFinder        = movieFinder;\n                    }\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Kotlin\n\n\n              class    SimpleMovieLister       {\n\n\n                    //  a  late-initialized       property    so   that  the   Spring    container    can   inject   a\n              MovieFinder\n                    lateinit    var   movieFinder:      MovieFinder\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            The  ApplicationContext      supports    constructor-based       and  setter-based    DI  for the  beans   it manages.    It\n            also supports setter-based DI after some dependencies have already been injected through the\n            constructor    approach.    You   configure    the  dependencies      in the  form   of  a BeanDefinition,     which    you\n            use  in conjunction     with  PropertyEditor     instances    to convert   properties    from   one  format   to  another.\n            However,    most   Spring   users   do  not  work   with   these  classes  directly   (that is, programmatically)       but\n            rather  with   XML   bean  definitions,   annotated    components      (that  is,  classes annotated    with  @Component,\n            @Controller,   and   so forth),  or @Bean   methods    in  Java-based    @Configuration     classes.  These   sources   are\n            then converted internally into instances of BeanDefinition and used to load an entire Spring IoC\n            container   instance.\n\n                                           Constructor-based              or  setter-based          DI?\n\n               Since   you   can  mix   constructor-based       and  setter-based     DI, it is a  good   rule  of thumb     to use\n               constructors     for  mandatory      dependencies      and  setter   methods    or  configuration     methods     for\n               optional    dependencies.     Note   that  use  of  the  @Autowired      annotation     on  a setter   method    can\n               be  used   to make   the  property    be  a required    dependency;     however,     constructor    injection   with\n               programmatic       validation   of arguments      is  preferable.\n\n               The    Spring    team    generally     advocates     constructor     injection,    as  it  lets  you    implement\n               application components as immutable objects and ensures that required dependencies are\n               not null. Furthermore, constructor-injected components are always returned to the client\n               (calling) code in a fully initialized state. As a side note, a large number of constructor\n               arguments     is a bad   code  smell,  implying    that  the class  likely  has  too many    responsibilities    and\n               should   be  refactored    to better  address    proper   separation    of concerns.\n\n\n               Setter  injection   should   primarily    only  be  used   for optional   dependencies      that  can  be  assigned\n               reasonable default values within the class. Otherwise, not-null checks must be performed\n               everywhere the code uses the dependency. One benefit of setter injection is that setter\n               methods make objects of that class amenable to reconfiguration or re-injection later.\n               Management       through    JMX   MBeans     is  therefore  a compelling    use  case  for  setter  injection.\n\n\n               Use   the  DI  style that  makes     the  most   sense   for a  particular   class.  Sometimes,     when    dealing\n               with   third-party   classes   for which   you   do  not  have  the  source,   the  choice  is made    for you.  For\n               example,    if a third-party    class  does  not  expose   any   setter  methods,    then  constructor     injection\n               may   be  the  only  available   form   of DI.\n\n\n\n\n\n            Dependency    Resolution   Process\n\n            The  container    performs    bean   dependency      resolution   as  follows:\n\n\n              • The   ApplicationContext      is created   and   initialized  with  configuration     metadata     that  describes   all\n                the  beans.  Configuration     metadata     can  be  specified   by XML,   Java   code,  or annotations.\n\n              • For  each  bean,   its dependencies      are expressed     in the  form  of  properties,   constructor    arguments,\n                or arguments to the static-factory method (if you use that instead of a normal constructor).\n                These   dependencies      are  provided    to the bean,   when    the bean   is actually   created.\n\n              • Each   property    or constructor    argument     is an  actual   definition   of the  value  to  set,  or  a reference\n                to another    bean   in the  container.\n\n              • Each   property    or constructor     argument     that  is  a  value  is  converted  from   its  specified format    to\n                the  actual  type  of  that property    or  constructor    argument.     By default,   Spring   can  convert   a value\n                supplied   in  string  format   to all built-in  types,  such  as int,  long, String,   boolean,  and   so forth.\n\n            The  Spring   container    validates   the configuration     of each   bean   as the  container    is  created. However,\n            the bean properties themselves are not set until the bean is actually created. Beans that are\n            singleton-scoped and set to be pre-instantiated (the default) are created when the container is\n            created. Scopes are defined in Bean Scopes. Otherwise, the bean is created only when it is\n            requested. Creation of a bean potentially causes a graph of beans to be created, as the bean’s\n            dependencies      and  its dependencies'      dependencies      (and  so  on)  are  created   and   assigned.    Note  that\n\n            resolution   mismatches      among     those  dependencies      may    show   up  late — that    is,  on  first  creation of\n            the affected   bean.\n\n\n                                                       Circular       dependencies\n\n               If you use predominantly constructor injection, it is possible to create an unresolvable\n               circular   dependency      scenario.\n\n\n               For  example:    Class  A  requires   an  instance   of class  B through    constructor    injection,   and  class  B\n               requires an instance of class A through constructor injection. If you configure beans for\n               classes   A  and  B  to be  injected   into  each   other,  the  Spring   IoC  container    detects   this  circular\n               reference    at runtime,    and  throws    a BeanCurrentlyInCreationException.\n\n\n               One   possible    solution   is to edit  the  source   code   of  some   classes   to be   configured    by  setters\n               rather than constructors. Alternatively, avoid constructor injection and use setter injection\n               only.   In   other    words,    although     it  is  not    recommended,        you    can    configure     circular\n               dependencies      with  setter  injection.\n\n\n               Unlike   the  typical  case  (with   no  circular  dependencies),      a circular   dependency      between    bean\n               A and bean B forces one of the beans to be injected into the other prior to being fully\n               initialized   itself  (a  classic  chicken-and-egg   scenario).\n\n\n\n            You can generally trust Spring to do the right thing. It detects configuration problems, such as\n            references to non-existent beans and circular dependencies, at container load-time. Spring sets\n            properties    and  resolves    dependencies      as late  as  possible,   when    the  bean   is actually   created.   This\n            means    that a  Spring   container    that  has  loaded   correctly   can  later  generate    an  exception    when    you\n            request an object if there is a problem creating that object or one of its dependencies — for\n            example,    the bean   throws    an  exception    as a  result  of a missing   or  invalid   property.   This  potentially\n            delayed visibility of some configuration issues is why ApplicationContext implementations by\n            default pre-instantiate singleton beans. At the cost of some upfront time and memory to create\n            these   beans    before    they    are   actually   needed,     you    discover    configuration      issues   when     the\n            ApplicationContext      is created,  not  later. You   can  still  override  this default   behavior    so that  singleton\n            beans   initialize lazily, rather   than  being   eagerly   pre-instantiated.\n\n\n            If  no circular  dependencies      exist,  when    one  or  more   collaborating     beans   are  being   injected   into  a\n            dependent bean, each collaborating bean is totally configured prior to being injected into the\n            dependent     bean.  This   means    that, if bean   A  has  a dependency      on  bean   B, the  Spring   IoC  container\n            completely    configures    bean    B prior   to invoking    the  setter  method     on  bean   A. In  other   words,   the\n            bean is instantiated (if it is not a pre-instantiated singleton), its dependencies are set, and the\n            relevant lifecycle methods (such as a configured init method or the InitializingBean callback\n            method)    are  invoked.\n\n\n\n            Examples   of Dependency     Injection\n\n            The  following    example    uses  XML-based      configuration     metadata     for setter-based    DI. A  small   part  of\n            a Spring   XML   configuration     file specifies  some   bean   definitions   as  follows:\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <!--   setter   injection     using   the   nested   ref   element    -->\n                    <property     name=\"beanOne\">\n                         <ref   bean=\"anotherExampleBean\"/>\n                    </property>\n\n\n                    <!--   setter   injection     using   the   neater   ref   attribute     -->\n                    <property     name=\"beanTwo\"      ref=\"yetAnotherBean\"/>\n                    <property     name=\"integerProperty\"         value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    private    AnotherBean     beanOne;\n\n\n                    private    YetAnotherBean      beanTwo;\n\n\n                    private    int  i;\n\n\n                    public   void   setBeanOne(AnotherBean          beanOne)    {\n                         this.beanOne      =  beanOne;\n                    }\n\n\n                    public   void   setBeanTwo(YetAnotherBean           beanTwo)    {\n                         this.beanTwo      =  beanTwo;\n                    }\n\n\n                    public   void   setIntegerProperty(int          i)  {\n                         this.i    =  i;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     {\n                    lateinit    var   beanOne:    AnotherBean\n                    lateinit    var   beanTwo:    YetAnotherBean\n                    var  i:  Int   =  0\n              }\n\n\n\n            In the  preceding    example,    setters  are  declared    to match   against   the  properties    specified  in  the XML\n\n            file.  The  following  example    uses  constructor-based       DI:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <!--   constructor     injection     using   the   nested   ref   element    -->\n                    <constructor-arg>\n                         <ref   bean=\"anotherExampleBean\"/>\n                    </constructor-arg>\n\n\n                    <!--   constructor     injection     using   the   neater   ref   attribute     -->\n                    <constructor-arg       ref=\"yetAnotherBean\"/>\n\n\n                    <constructor-arg       type=\"int\"     value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    private    AnotherBean     beanOne;\n\n\n                    private    YetAnotherBean      beanTwo;\n\n\n                    private    int  i;\n\n\n                    public   ExampleBean(\n                         AnotherBean      anotherBean,      YetAnotherBean      yetAnotherBean,       int   i)  {\n                         this.beanOne      =  anotherBean;\n                         this.beanTwo      =  yetAnotherBean;\n                         this.i    =  i;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean(\n                         private    val   beanOne:    AnotherBean,\n                         private    val   beanTwo:    YetAnotherBean,\n                         private    val   i:  Int)\n\n\n\n            The constructor arguments specified in the bean definition are used as arguments to the\n            constructor    of the  ExampleBean.\n\n\n            Now   consider    a variant   of this  example,    where,   instead   of using   a constructor,    Spring   is told  to call\n            a static  factory   method    to return   an  instance   of the  object:\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\"            factory-method=\"createInstance\">\n                    <constructor-arg       ref=\"anotherExampleBean\"/>\n                    <constructor-arg       ref=\"yetAnotherBean\"/>\n                    <constructor-arg       value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    //  a  private    constructor\n                    private    ExampleBean(...)       {\n                         ...\n                    }\n\n\n                    //  a  static   factory    method;    the   arguments     to  this   method   can   be\n                    //  considered     the   dependencies     of   the  bean   that   is  returned,\n                    //  regardless     of  how   those   arguments     are  actually     used.\n                    public   static    ExampleBean      createInstance      (\n                         AnotherBean      anotherBean,      YetAnotherBean      yetAnotherBean,       int   i)  {\n\n\n                         ExampleBean      eb  =  new  ExampleBean      (...);\n                         //  some   other    operations...\n                         return    eb;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     private    constructor()      {\n                    companion     object   {\n                         //  a  static    factory    method;    the  arguments     to  this   method    can  be\n                         //  considered      the  dependencies      of  the   bean  that   is  returned,\n                         //  regardless      of  how  those   arguments     are   actually    used.\n                         @JvmStatic\n                         fun   createInstance(anotherBean:           AnotherBean,      yetAnotherBean:       YetAnotherBean,\n              i:  Int):    ExampleBean     {\n                               val  eb  =  ExampleBean      (...)\n                               //  some   other   operations...\n                               return   eb\n                         }\n                    }\n              }\n\n            Arguments     to  the  static   factory  method     are  supplied    by  <constructor-arg/>      elements,    exactly   the\n            same   as if a constructor    had   actually   been  used.   The  type  of  the class  being   returned    by  the factory\n            method    does   not  have   to be  of  the same    type  as  the  class  that  contains   the  static   factory   method\n            (although, in this example, it is). An instance (non-static) factory method can be used in an\n            essentially   identical   fashion   (aside  from    the  use  of the  factory-bean     attribute   instead   of  the  class\n            attribute),  so we   do not  discuss   those  details  here.\n\n\n            Dependencies       and  Configuration       in Detail\n\n            As mentioned      in the previous    section,  you   can  define  bean   properties    and  constructor    arguments      as\n            references    to other  managed      beans   (collaborators)    or  as values   defined    inline. Spring’s   XML-based\n            configuration     metadata    supports    sub-element      types  within   its <property/>     and   <constructor-arg/>\n            elements    for this purpose.\n\n\n\n            Straight Values  (Primitives,  Strings,  and  so on)\n\n            The  value   attribute   of the  <property/>     element    specifies   a property    or  constructor     argument     as  a\n            human-readable       string  representation.      Spring’s   conversion    service   is used   to convert    these  values\n            from   a String  to  the actual   type  of the  property    or argument.     The  following    example    shows    various\n            values  being   set:\n\n\n\n              <bean    id=\"myDataSource\"       class=\"org.apache.commons.dbcp.BasicDataSource\"                   destroy-\n              method=\"close\">\n                    <!--   results    in  a  setDriverClassName(String)           call   -->\n                    <property     name=\"driverClassName\"         value=\"com.mysql.jdbc.Driver\"/>\n                    <property     name=\"url\"     value=\"jdbc:mysql://localhost:3306/mydb\"/>\n                    <property     name=\"username\"       value=\"root\"/>\n                    <property     name=\"password\"       value=\"misterkaoli\"/>\n              </bean>\n\n\n\n            The  following   example     uses  the  p-namespace      for even   more   succinct   XML   configuration:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                    https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"myDataSource\"        class=\"org.apache.commons.dbcp.BasicDataSource\"\n                         destroy-method=\"close\"\n                         p:driverClassName=\"com.mysql.jdbc.Driver\"\n                         p:url=\"jdbc:mysql://localhost:3306/mydb\"\n                         p:username=\"root\"\n                         p:password=\"misterkaoli\"/>\n\n\n              </beans>\n\n\n\n            The  preceding    XML    is more   succinct.   However,     typos  are  discovered     at runtime    rather   than  design\n\n            time, unless you use an IDE (such as IntelliJ IDEA or the Spring Tools for Eclipse) that supports\n            automatic property completion when you create bean definitions. Such IDE assistance is highly\n            recommended.\n\n\n            You  can  also  configure   a  java.util.Properties      instance,   as  follows:\n\n\n\n              <bean    id=\"mappings\"\n                    class=\"org.springframework.context.support.PropertySourcesPlaceholderConfigurer\">\n\n\n                    <!--   typed   as  a  java.util.Properties         -->\n                    <property     name=\"properties\">\n                         <value>\n                               jdbc.driver.className=com.mysql.jdbc.Driver\n                               jdbc.url=jdbc:mysql://localhost:3306/mydb\n                         </value>\n                    </property>\n              </bean>\n\n\n\n            The Spring container converts the text inside the <value/> element into a java.util.Properties\n            instance   by  using  the  JavaBeans     PropertyEditor     mechanism.      This  is a  nice  shortcut,   and  is one  of  a\n            few  places   where    the  Spring   team   do  favor   the  use  of the  nested    <value/>   element    over   the  value\n            attribute  style.\n\n\n            The  idref  element\n\n            The  idref   element    is simply   an  error-proof    way   to  pass  the  id (a  string  value   -  not a reference)    of\n            another bean in the container to a <constructor-arg/> or <property/> element. The following\n            example    shows   how    to use  it:\n\n\n\n              <bean    id=\"theTargetBean\"        class=\"...\"/>\n\n\n              <bean    id=\"theClientBean\"        class=\"...\">\n                    <property     name=\"targetName\">\n                         <idref    bean=\"theTargetBean\"/>\n                    </property>\n              </bean>\n\n\n\n            The  preceding    bean   definition   snippet   is exactly  equivalent    (at runtime)    to the  following   snippet:\n\n\n\n              <bean    id=\"theTargetBean\"        class=\"...\"     />\n\n\n              <bean    id=\"client\"     class=\"...\">\n                    <property     name=\"targetName\"       value=\"theTargetBean\"/>\n              </bean>\n\n\n\n            The  first form   is preferable    to the  second,   because    using  the  idref   tag lets the  container    validate   at\n            deployment time that the referenced, named bean actually exists. In the second variation, no\n\n            validation   is performed      on  the  value   that is passed    to the  targetName    property    of  the  client  bean.\n            Typos are only discovered (with most likely fatal results) when the client bean is actually\n            instantiated.   If the  client  bean   is a  prototype    bean,  this  typo  and   the  resulting   exception    may   only\n            be discovered     long  after the  container    is  deployed.\n\n\n                              The  local   attribute   on  the  idref   element    is no  longer   supported     in the  4.0  beans\n                              XSD, since it does not provide value over a regular bean reference any more.\n                             Change    your  existing   idref   local   references    to idref   bean  when    upgrading     to the\n                              4.0 schema.\n\n\n            A common      place   (at least  in  versions   earlier   than   Spring   2.0)  where    the  <idref/>   element    brings\n            value is in the configuration of AOP interceptors in a ProxyFactoryBean bean definition. Using\n            <idref/> elements when you specify the interceptor names prevents you from misspelling an\n            interceptor   ID.\n\n\n\n            References   to Other  Beans  (Collaborators)\n\n            The  ref  element    is the  final element    inside   a <constructor-arg/>      or  <property/>    definition   element.\n            Here, you set the value of the specified property of a bean to be a reference to another bean (a\n            collaborator)    managed     by  the  container.    The  referenced     bean   is a  dependency      of the  bean   whose\n            property    is to be  set, and   it is initialized   on  demand     as  needed    before   the  property    is set. (If the\n            collaborator    is a singleton    bean,  it may   already    be  initialized  by  the  container.)    All references    are\n            ultimately   a reference    to another    object.  Scoping   and   validation   depend    on  whether    you   specify  the\n            ID or  name   of the  other   object  through    the bean  or  parent  attribute.\n\n\n            Specifying   the  target  bean   through    the  bean  attribute   of the  <ref/>  tag  is the most   general    form  and\n            allows  creation    of a reference    to any   bean   in the  same   container    or parent    container,   regardless    of\n            whether it is in the same XML file. The value of the bean attribute may be the same as the id\n            attribute   of the  target  bean   or  be  the  same   as  one   of the  values   in the  name   attribute   of the  target\n            bean.  The  following    example    shows    how   to use  a ref  element:\n\n\n\n              <ref   bean=\"someBean\"/>\n\n\n\n            Specifying    the  target  bean   through    the  parent   attribute   creates   a  reference    to a  bean   that  is in  a\n            parent container of the current container. The value of the parent attribute may be the same as\n            either  the id  attribute  of  the target  bean   or  one  of the  values   in the  name  attribute  of  the target  bean.\n            The target bean must be in a parent container of the current one. You should use this bean\n            reference variant mainly when you have a hierarchy of containers and you want to wrap an\n            existing  bean   in  a parent   container    with   a proxy    that  has  the  same   name    as  the  parent   bean.   The\n            following   pair  of listings  shows   how   to use  the  parent   attribute:\n\n\n\n              <!--   in  the   parent   context    -->\n              <bean    id=\"accountService\"        class=\"com.something.SimpleAccountService\">\n                    <!--   insert   dependencies      as  required     here   -->\n              </bean>\n\n              <!--   in  the   child   (descendant)      context    -->\n              <bean    id=\"accountService\"        <!--   bean   name   is  the  same   as  the   parent   bean   -->\n                    class=\"org.springframework.aop.framework.ProxyFactoryBean\">\n                    <property     name=\"target\">\n                         <ref   parent=\"accountService\"/>           <!--   notice   how   we  refer   to  the   parent    bean  -->\n                    </property>\n                    <!--   insert   other    configuration      and  dependencies      as  required     here   -->\n              </bean>\n\n\n\n\n                              The  local  attribute   on  the  ref element    is no  longer   supported    in the  4.0 beans    XSD,\n                             since it does not provide value over a regular bean reference any more. Change\n                              your  existing   ref  local  references    to ref  bean  when    upgrading     to the 4.0  schema.\n\n\n\n            Inner Beans\n\n            A <bean/>   element    inside   the  <property/>    or  <constructor-arg/>      elements    defines   an  inner   bean,   as\n            the following    example    shows:\n\n\n\n              <bean    id=\"outer\"     class=\"...\">\n                    <!--   instead    of  using   a  reference     to  a target    bean,   simply    define    the  target    bean\n              inline    -->\n                    <property     name=\"target\">\n                         <bean    class=\"com.example.Person\">           <!--   this   is  the  inner    bean   -->\n                               <property     name=\"name\"     value=\"Fiona      Apple\"/>\n                               <property     name=\"age\"     value=\"25\"/>\n                         </bean>\n                    </property>\n              </bean>\n\n\n\n            An  inner  bean   definition   does   not  require   a defined   ID  or name.    If specified,  the  container    does  not\n            use such a value as an identifier. The container also ignores the scope flag on creation, because\n            inner  beans   are  always   anonymous       and  are  always    created   with  the  outer  bean.   It  is  not  possible  to\n            access inner beans independently or to inject them into collaborating beans other than into the\n            enclosing   bean.\n\n\n            As a  corner   case,  it  is  possible  to  receive  destruction  callbacks    from   a custom    scope — for    example,\n            for a request-scoped      inner   bean   contained    within   a singleton    bean.  The   creation   of  the inner   bean\n            instance is tied to its containing bean, but destruction callbacks let it participate in the request\n            scope’s  lifecycle.  This  is  not  a common    scenario.   Inner   beans   typically  simply   share   their  containing\n            bean’s  scope.\n\n\n\n            Collections\n\n            The <list/>, <set/>, <map/>, and <props/> elements set the properties and arguments of the Java\n            Collection    types  List,  Set,  Map, and   Properties,    respectively.   The   following    example     shows   how    to\n            use them:\n\n              <bean    id=\"moreComplexObject\"         class=\"example.ComplexObject\">\n                    <!--   results    in  a  setAdminEmails(java.util.Properties)              call   -->\n                    <property     name=\"adminEmails\">\n                         <props>\n                               <prop   key=\"administrator\">administrator@example.org</prop>\n                               <prop   key=\"support\">support@example.org</prop>\n                               <prop   key=\"development\">development@example.org</prop>\n                         </props>\n                    </property>\n                    <!--   results    in  a  setSomeList(java.util.List)           call   -->\n                    <property     name=\"someList\">\n                         <list>\n                               <value>a    list   element    followed    by   a reference</value>\n                               <ref   bean=\"myDataSource\"        />\n                         </list>\n                    </property>\n                    <!--   results    in  a  setSomeMap(java.util.Map)          call   -->\n                    <property     name=\"someMap\">\n                         <map>\n                               <entry   key=\"an    entry\"    value=\"just      some  string\"/>\n                               <entry   key=\"a    ref\"   value-ref=\"myDataSource\"/>\n                         </map>\n                    </property>\n                    <!--   results    in  a  setSomeSet(java.util.Set)          call   -->\n                    <property     name=\"someSet\">\n                         <set>\n                               <value>just     some   string</value>\n                               <ref   bean=\"myDataSource\"        />\n                         </set>\n                    </property>\n              </bean>\n\n\n\n            The  value  of  a map   key  or  value,  or a set  value,  can  also  be any  of  the following    elements:\n\n\n\n              bean   |  ref  |  idref   |  list   |  set  |  map   | props    | value    | null\n\n\n\n            Collection    Merging\n\n            The Spring container also supports merging collections. An application developer can define a\n            parent   <list/>,  <map/>,  <set/>   or  <props/>   element    and  have   child  <list/>,  <map/>,   <set/>  or  <props/>\n            elements inherit and override values from the parent collection. That is, the child collection’s\n            values   are  the  result  of merging     the  elements    of the  parent    and  child   collections,   with  the  child’s\n            collection  elements    overriding    values   specified   in the  parent   collection.\n\n\n            This section on merging discusses the parent-child bean mechanism. Readers unfamiliar with\n            parent   and  child  bean   definitions   may   wish   to read  the  relevant   section   before  continuing.\n\n\n            The  following   example     demonstrates     collection   merging:\n\n              <beans>\n                    <bean   id=\"parent\"      abstract=\"true\"       class=\"example.ComplexObject\">\n                         <property     name=\"adminEmails\">\n                               <props>\n                                    <prop    key=\"administrator\">administrator@example.com</prop>\n                                    <prop    key=\"support\">support@example.com</prop>\n                               </props>\n                         </property>\n                    </bean>\n                    <bean   id=\"child\"     parent=\"parent\">\n                         <property     name=\"adminEmails\">\n                               <!--   the  merge   is   specified    on  the   child   collection     definition     -->\n                               <props   merge=\"true\">\n                                    <prop    key=\"sales\">sales@example.com</prop>\n                                    <prop    key=\"support\">support@example.co.uk</prop>\n                               </props>\n                         </property>\n                    </bean>\n              <beans>\n\n\n\n            Notice  the  use  of the  merge=true    attribute  on  the  <props/>   element    of the  adminEmails    property    of the\n            child bean definition. When the child bean is resolved and instantiated by the container, the\n            resulting   instance   has  an  adminEmails     Properties    collection   that  contains   the  result  of  merging    the\n            child’s  adminEmails    collection   with   the  parent’s   adminEmails    collection.   The   following    listing shows\n            the result:\n\n\n\n              administrator=administrator@example.com\n              sales=sales@example.com\n              support=support@example.co.uk\n\n\n\n            The  child  Properties    collection’s   value   set inherits   all property    elements    from   the  parent   <props/>,\n            and  the  child’s value   for the  support   value  overrides    the  value  in  the parent   collection.\n\n\n            This  merging    behavior     applies   similarly   to the  <list/>,   <map/>,   and  <set/>   collection   types.   In the\n            specific  case  of the  <list/>   element,    the  semantics    associated    with   the List   collection   type  (that  is,\n            the notion    of an  ordered   collection   of  values)  is maintained.     The   parent’s   values   precede    all of the\n            child list’s values. In the case of the Map, Set, and Properties collection types, no ordering exists.\n            Hence,   no  ordering    semantics    are  in effect  for  the collection   types   that  underlie   the  associated    Map,\n            Set, and  Properties    implementation       types  that  the container    uses  internally.\n\n\n            Limitations     of Collection    Merging\n\n            You  cannot   merge    different   collection  types   (such  as  a Map and   a List).  If  you do  attempt   to do  so, an\n            appropriate    Exception    is  thrown.  The  merge   attribute  must   be  specified   on  the lower,   inherited,   child\n            definition.  Specifying    the  merge  attribute   on a  parent   collection  definition    is  redundant   and   does  not\n            result in  the desired   merging.\n\n            Strongly-typed      collection\n\n            Thanks to Java’s support for generic types, you can use strongly typed collections. That is, it is\n            possible   to declare   a Collection    type  such   that  it  can  only contain   (for example)     String   elements.   If\n            you use Spring to dependency-inject a strongly-typed Collection into a bean, you can take\n            advantage of Spring’s type-conversion support such that the elements of your strongly-typed\n            Collection    instances   are  converted     to the  appropriate     type  prior  to  being   added   to  the Collection.\n            The  following   Java   class and   bean  definition   show    how   to do  so:\n\n\n            Java\n\n\n              public    class   SomeClass     {\n\n\n                    private    Map<String,     Float>    accounts;\n\n\n                    public   void   setAccounts(Map<String,          Float>    accounts)     {\n                         this.accounts       = accounts;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    SomeClass    {\n                    lateinit    var   accounts:    Map<String,      Float>\n              }\n\n\n\n\n              <beans>\n                    <bean   id=\"something\"       class=\"x.y.SomeClass\">\n                         <property     name=\"accounts\">\n                               <map>\n                                    <entry    key=\"one\"     value=\"9.99\"/>\n                                    <entry    key=\"two\"     value=\"2.75\"/>\n                                    <entry    key=\"six\"     value=\"3.99\"/>\n                               </map>\n                         </property>\n                    </bean>\n              </beans>\n\n\n\n            When     the   accounts    property     of  the   something     bean    is  prepared     for   injection,   the   generics\n            information about the element type of the strongly-typed Map<String, Float> is available by\n            reflection.  Thus,   Spring’s   type  conversion     infrastructure     recognizes    the  various    value  elements     as\n            being  of  type  Float,  and   the  string  values   (9.99,  2.75,  and  3.99)   are  converted    into  an  actual   Float\n            type.\n\n\n\n            Null and  Empty   String Values\n\n            Spring   treats  empty    arguments     for  properties    and   the  like  as empty    Strings.   The   following    XML-\n            based   configuration    metadata     snippet   sets the  email  property    to the empty    String   value  (\"\").\n\n              <bean    class=\"ExampleBean\">\n                    <property     name=\"email\"     value=\"\"/>\n              </bean>\n\n\n\n            The  preceding    example    is equivalent    to the  following    Java  code:\n\n\n            Java\n\n\n              exampleBean.setEmail(\"\");\n\n\n\n            Kotlin\n\n\n              exampleBean.email        =  \"\"\n\n\n\n            The  <null/>   element    handles   null  values.  The   following   listing  shows   an  example:\n\n\n\n              <bean    class=\"ExampleBean\">\n                    <property     name=\"email\">\n                         <null/>\n                    </property>\n              </bean>\n\n\n\n            The  preceding    configuration     is  equivalent   to the following    Java  code:\n\n\n            Java\n\n\n              exampleBean.setEmail(null);\n\n\n\n            Kotlin\n\n\n              exampleBean.email        =  null\n\n\n\n\n            XML  Shortcut   with  the p-namespace\n\n            The  p-namespace      lets you   use  the bean  element’s    attributes   (instead   of nested   <property/>    elements)\n            to describe   your   property   values   collaborating    beans,   or both.\n\n\n            Spring supports extensible configuration formats with namespaces, which are based on an XML\n            Schema    definition.   The   beans  configuration     format    discussed    in this  chapter   is defined    in an  XML\n            Schema    document.     However,     the  p-namespace       is not  defined   in  an  XSD   file and  exists  only   in the\n            core  of Spring.\n\n\n            The following example shows two XML snippets (the first uses standard XML format and the\n            second   uses  the  p-namespace)      that resolve   to the  same   result:\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   name=\"classic\"       class=\"com.example.ExampleBean\">\n                         <property     name=\"email\"      value=\"someone@somewhere.com\"/>\n                    </bean>\n\n\n                    <bean   name=\"p-namespace\"        class=\"com.example.ExampleBean\"\n                         p:email=\"someone@somewhere.com\"/>\n              </beans>\n\n\n\n            The  example     shows    an  attribute   in the  p-namespace       called  email  in  the  bean   definition.   This  tells\n            Spring   to include   a property    declaration.    As  previously    mentioned,     the p-namespace       does  not  have\n            a schema    definition,   so you  can  set  the name    of the  attribute   to the property    name.\n\n\n            This  next  example    includes   two   more   bean   definitions   that  both  have   a reference    to another   bean:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   name=\"john-classic\"         class=\"com.example.Person\">\n                         <property     name=\"name\"      value=\"John     Doe\"/>\n                         <property     name=\"spouse\"      ref=\"jane\"/>\n                    </bean>\n\n\n                    <bean   name=\"john-modern\"\n                         class=\"com.example.Person\"\n                         p:name=\"John      Doe\"\n                         p:spouse-ref=\"jane\"/>\n\n\n                    <bean   name=\"jane\"      class=\"com.example.Person\">\n                         <property     name=\"name\"      value=\"Jane     Doe\"/>\n                    </bean>\n              </beans>\n\n\n\n            This example includes not only a property value using the p-namespace but also uses a special\n            format    to   declare    property     references.     Whereas       the   first  bean    definition     uses   <property\n            name=\"spouse\" ref=\"jane\"/> to create a reference from bean john to bean jane, the second bean\n            definition   uses  p:spouse-ref=\"jane\"       as an  attribute   to do  the exact   same   thing.  In this  case,  spouse  is\n            the property name, whereas the -ref part indicates that this is not a straight value but rather a\n            reference   to another    bean.\n\n                              The  p-namespace       is  not  as  flexible  as  the  standard  XML    format.   For  example,    the\n                              format   for  declaring    property    references    clashes   with   properties   that  end   in  Ref,\n                             whereas    the  standard    XML   format    does  not.  We   recommend       that  you  choose   your\n                              approach     carefully    and    communicate        this  to   your   team    members       to  avoid\n                              producing    XML    documents     that  use  all  three approaches     at the  same   time.\n\n\n\n            XML  Shortcut   with  the c-namespace\n\n            Similar to the XML Shortcut with the p-namespace, the c-namespace, introduced in Spring 3.1,\n            allows  inlined   attributes   for configuring     the constructor    arguments      rather  then   nested   constructor-\n            arg elements.\n\n\n            The  following    example    uses   the  c: namespace      to do  the  same    thing  as the  from   Constructor-based\n            Dependency      Injection:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:c=\"http://www.springframework.org/schema/c\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"beanTwo\"      class=\"x.y.ThingTwo\"/>\n                    <bean   id=\"beanThree\"       class=\"x.y.ThingThree\"/>\n\n\n                    <!--   traditional     declaration      with   optional    argument    names    -->\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\">\n                         <constructor-arg        name=\"thingTwo\"       ref=\"beanTwo\"/>\n                         <constructor-arg        name=\"thingThree\"       ref=\"beanThree\"/>\n                         <constructor-arg        name=\"email\"      value=\"something@somewhere.com\"/>\n                    </bean>\n\n\n                    <!--   c-namespace     declaration      with   argument    names   -->\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\"         c:thingTwo-ref=\"beanTwo\"\n                         c:thingThree-ref=\"beanThree\"            c:email=\"something@somewhere.com\"/>\n\n\n              </beans>\n\n\n\n            The  c: namespace      uses   the same    conventions     as the  p: one   (a trailing  -ref  for  bean   references)    for\n            setting  the  constructor    arguments     by  their  names.   Similarly,   it needs   to be  declared   in  the  XML   file\n            even  though    it  is  not  defined  in  an  XSD  schema  (it  exists  inside  the  Spring core).\n\n            For the  rare  cases   where   the  constructor    argument     names    are  not  available   (usually   if  the  bytecode\n            was   compiled    without    debugging     information),     you   can  use  fallback   to  the  argument     indexes,    as\n            follows:\n\n              <!--   c-namespace      index   declaration     -->\n              <bean    id=\"beanOne\"     class=\"x.y.ThingOne\"         c:_0-ref=\"beanTwo\"        c:_1-ref=\"beanThree\"\n                    c:_2=\"something@somewhere.com\"/>\n\n\n\n\n                              Due  to  the XML    grammar,     the  index   notation    requires   the  presence    of the  leading\n                              _, as XML attribute names cannot start with a number (even though some IDEs\n                             allow it). A corresponding index notation is also available for <constructor-arg>\n                              elements but not commonly used since the plain order of declaration is usually\n                              sufficient  there.\n\n\n            In practice, the constructor resolution mechanism is quite efficient in matching arguments, so\n            unless  you   really need   to, we  recommend       using   the name    notation   throughout     your   configuration.\n\n\n\n            Compound     Property  Names\n\n            You can use compound or nested property names when you set bean properties, as long as all\n            components      of the  path   except   the  final property    name    are  not   null. Consider    the  following    bean\n            definition:\n\n\n\n              <bean    id=\"something\"      class=\"things.ThingOne\">\n                    <property     name=\"fred.bob.sammy\"         value=\"123\"     />\n              </bean>\n\n\n\n            The  something    bean   has  a fred  property,    which   has  a  bob property,    which   has  a  sammy  property,   and\n            that final  sammy  property    is being  set  to a value   of 123. In  order  for  this to work,   the  fred  property    of\n            something   and   the  bob property    of  fred  must   not  be  null  after  the bean   is constructed.    Otherwise,     a\n            NullPointerException      is thrown.\n\n\n            Using   depends-on\n\n            If  a  bean is  a  dependency    of another    bean,  that  usually   means    that  one  bean   is set as  a property    of\n            another. Typically you accomplish this with the <ref/> element in XML-based configuration\n            metadata.    However,     sometimes     dependencies      between    beans   are  less  direct. An   example    is when    a\n            static initializer in a class needs to be triggered, such as for database driver registration. The\n            depends-on    attribute   can  explicitly  force   one  or  more   beans    to be  initialized  before   the  bean   using\n            this element is initialized. The following example uses the depends-on attribute to express a\n            dependency     on  a single   bean:\n\n\n\n              <bean    id=\"beanOne\"     class=\"ExampleBean\"         depends-on=\"manager\"/>\n              <bean    id=\"manager\"     class=\"ManagerBean\"         />\n\n\n\n            To express    a dependency      on  multiple   beans,   supply   a list  of  bean  names  as  the value   of the  depends-\n            on attribute   (commas,    whitespace,     and  semicolons     are valid  delimiters):\n\n              <bean    id=\"beanOne\"     class=\"ExampleBean\"         depends-on=\"manager,accountDao\">\n                    <property     name=\"manager\"      ref=\"manager\"      />\n              </bean>\n\n\n              <bean    id=\"manager\"     class=\"ManagerBean\"         />\n              <bean    id=\"accountDao\"       class=\"x.y.jdbc.JdbcAccountDao\"             />\n\n\n\n\n                              The  depends-on    attribute  can   specify  both   an initialization-time     dependency      and,  in\n                              the case of singleton beans only, a corresponding destruction-time dependency.\n                             Dependent beans that define a depends-on relationship with a given bean are\n                              destroyed    first,  prior  to  the  given  bean itself being   destroyed.   Thus,   depends-on    can\n                              also control   shutdown     order.\n\n\n\n            Lazy-initialized     Beans\n\n            By  default,  ApplicationContext      implementations       eagerly   create   and  configure    all singleton   beans    as\n            part  of the  initialization  process.   Generally,    this pre-instantiation     is desirable,   because   errors   in the\n            configuration or surrounding environment are discovered immediately, as opposed to hours or\n            even days later. When this behavior is not desirable, you can prevent pre-instantiation of a\n            singleton   bean   by  marking    the  bean   definition   as being   lazy-initialized.   A  lazy-initialized   bean   tells\n            the IoC  container    to create  a bean   instance   when    it is  first  requested, rather   than  at startup.\n\n\n            In XML, this behavior is controlled by the lazy-init attribute on the <bean/> element, as the\n            following   example    shows:\n\n\n\n              <bean    id=\"lazy\"    class=\"com.something.ExpensiveToCreateBean\"                  lazy-init=\"true\"/>\n              <bean    name=\"not.lazy\"       class=\"com.something.AnotherBean\"/>\n\n\n\n            When the preceding configuration is consumed by an ApplicationContext, the lazy bean is not\n            eagerly   pre-instantiated     when    the  ApplicationContext      starts,  whereas    the  not.lazy    bean   is eagerly\n            pre-instantiated.\n\n\n            However, when a lazy-initialized bean is a dependency of a singleton bean that is not lazy-\n            initialized, the ApplicationContext creates the lazy-initialized bean at startup, because it must\n            satisfy the singleton’s dependencies. The lazy-initialized bean is injected into a singleton bean\n            elsewhere    that  is  not  lazy-initialized.\n\n            You can also control lazy-initialization at the container level by using the default-lazy-init\n            attribute  on  the  <beans/>   element,   as  the following    example    shows:\n\n\n\n              <beans    default-lazy-init=\"true\">\n                    <!--   no  beans   will   be  pre-instantiated...         -->\n              </beans>\n\n            Autowiring     Collaborators\n\n            The  Spring   container    can   autowire    relationships     between    collaborating     beans.   You  can   let Spring\n            resolve   collaborators    (other   beans)   automatically     for  your   bean   by  inspecting    the  contents    of the\n            ApplicationContext.      Autowiring    has  the  following    advantages:\n\n              • Autowiring can significantly reduce the need to specify properties or constructor arguments.\n                (Other mechanisms such as a bean template discussed elsewhere in this chapter are also\n                valuable    in this regard.)\n\n              • Autowiring     can  update    a configuration    as  your  objects   evolve.  For  example,    if you  need   to add   a\n                dependency      to  a class,  that dependency       can  be  satisfied  automatically     without    you   needing    to\n                modify the configuration. Thus autowiring can be especially useful during development,\n                without    negating    the option   of  switching    to explicit  wiring    when    the code   base   becomes     more\n                stable.\n\n\n            When using XML-based configuration metadata (see Dependency Injection), you can specify the\n            autowire mode for a bean definition with the autowire attribute of the <bean/> element. The\n            autowiring functionality has four modes. You specify autowiring per bean and can thus choose\n            which   ones  to  autowire.   The   following   table  describes   the  four  autowiring     modes:\n\n\n            Table 2. Autowiring    modes\n\n            Mode                     Explanation\n            no                       (Default)   No  autowiring.    Bean   references    must   be  defined   by  ref elements.\n                                     Changing     the default   setting  is not  recommended       for  larger  deployments,\n                                     because    specifying   collaborators     explicitly  gives  greater   control  and   clarity. To\n                                     some    extent,  it  documents    the structure   of  a system.\n            byName                   Autowiring     by  property    name.   Spring   looks  for a  bean  with   the same    name   as\n                                     the  property    that needs   to be  autowired.    For  example,    if a bean   definition   is\n                                     set to  autowire    by name    and  it contains   a master   property    (that is, it  has  a\n                                     setMaster(..)     method),    Spring   looks  for a  bean  definition   named     master  and\n                                     uses  it to set the  property.\n            byType                   Lets  a property    be  autowired    if exactly  one   bean  of  the property    type  exists  in\n                                     the  container.   If more   than   one  exists, a  fatal exception    is  thrown,  which\n                                     indicates   that  you  may   not  use  byType   autowiring    for that  bean.   If  there are no\n                                     matching     beans,  nothing    happens    (the  property   is not  set).\n            constructor              Analogous     to byType   but  applies  to constructor    arguments.     If there  is not\n                                     exactly   one  bean   of the  constructor    argument     type  in the  container,   a fatal\n                                     error   is  raised.\n\n\n            With byType or constructor autowiring mode, you can wire arrays and typed collections. In such\n            cases,  all autowire    candidates     within   the  container    that  match    the  expected    type  are  provided     to\n            satisfy  the  dependency.     You   can  autowire     strongly-typed     Map  instances   if the  expected    key   type  is\n            String. An autowired Map instance’s values consist of all bean instances that match the expected\n            type, and   the Map  instance’s   keys  contain   the  corresponding      bean   names.\n\n            Limitations  and  Disadvantages    of Autowiring\n\n            Autowiring works best when it is used consistently across a project. If autowiring is not used in\n            general,  it might   be confusing    to developers     to use  it  to  wire  only  one  or  two  bean definitions.\n\n\n            Consider   the  limitations   and   disadvantages     of autowiring:\n\n              • Explicit  dependencies      in  property   and  constructor-arg      settings  always    override   autowiring.     You\n                cannot    autowire    simple   properties    such  as  primitives,   Strings,   and   Classes   (and  arrays   of such\n                simple   properties).   This  limitation   is by-design.\n\n              • Autowiring     is less  exact  than   explicit  wiring.   Although,    as  noted   in  the  earlier  table,  Spring   is\n                careful to avoid guessing in case of ambiguity that might have unexpected results. The\n                relationships    between    your   Spring-managed       objects   are  no longer   documented      explicitly.\n\n              • Wiring information may not be available to tools that may generate documentation from a\n                Spring   container.\n\n              • Multiple bean definitions within the container may match the type specified by the setter\n                method    or  constructor    argument     to be  autowired.    For  arrays,  collections,   or Map  instances,   this is\n                not  necessarily    a problem.    However,     for dependencies      that  expect   a single  value,  this  ambiguity\n                is not  arbitrarily  resolved.   If no  unique   bean   definition   is available,   an  exception   is thrown.\n\n\n            In the  latter scenario,   you  have   several   options:\n\n              • Abandon     autowiring     in favor  of explicit  wiring.\n\n              • Avoid   autowiring     for  a bean   definition    by  setting  its autowire-candidate       attributes   to false,   as\n                described    in the  next  section.\n\n              • Designate    a single  bean   definition   as the  primary    candidate    by  setting  the  primary  attribute   of its\n                <bean/>   element    to true.\n\n              • Implement the more fine-grained control available with annotation-based configuration, as\n                described    in Annotation-based       Container    Configuration.\n\n\n\n            Excluding   a  Bean from  Autowiring\n\n            On a per-bean basis, you can exclude a bean from autowiring. In Spring’s XML format, set the\n            autowire-candidate      attribute   of the  <bean/>  element    to false.  The   container    makes   that  specific  bean\n            definition   unavailable     to the  autowiring     infrastructure     (including   annotation     style  configurations\n            such  as @Autowired).\n\n\n                              The  autowire-candidate       attribute   is designed    to only  affect  type-based     autowiring.\n                              It does not affect explicit references by name, which get resolved even if the\n                             specified bean is not marked as an autowire candidate. As a consequence,\n                              autowiring    by  name    nevertheless    injects  a bean   if  the  name  matches.\n\n\n            You can also limit autowire candidates based on pattern-matching against bean names. The top-\n            level <beans/> element accepts one or more patterns within its default-autowire-candidates\n            attribute. For example, to limit autowire candidate status to any bean whose name ends with\n            Repository,   provide    a value   of *Repository.    To  provide    multiple   patterns,   define   them   in  a comma-\n            separated    list.  An  explicit  value of true  or  false  for  a bean   definition’s   autowire-candidate      attribute\n\n            always   takes  precedence.     For  such  beans,   the pattern   matching     rules  do  not apply.\n\n\n            These techniques are useful for beans that you never want to be injected into other beans by\n            autowiring. It does not mean that an excluded bean cannot itself be configured by using\n            autowiring.    Rather,   the bean   itself is not a  candidate    for autowiring    other   beans.\n\n\n            Method    Injection\n\n            In most   application    scenarios,    most   beans   in the  container    are   singletons.   When    a  singleton   bean\n            needs   to collaborate    with  another    singleton   bean   or a  non-singleton     bean   needs   to collaborate    with\n            another non-singleton bean, you typically handle the dependency by defining one bean as a\n            property    of the  other.  A  problem     arises  when    the  bean   lifecycles   are  different.  Suppose     singleton\n            bean   A  needs   to use   non-singleton     (prototype)    bean   B, perhaps     on  each   method    invocation     on  A.\n            The  container    creates   the singleton    bean   A only  once,   and  thus   only  gets  one  opportunity     to set the\n            properties.   The   container    cannot   provide    bean   A  with  a  new   instance   of  bean   B every   time   one  is\n            needed.\n\n            A solution   is to  forego   some   inversion    of control.   You  can   make   bean   A  aware    of the  container    by\n            implementing the ApplicationContextAware interface, and by making a getBean(\"B\") call to the\n            container ask for (a typically new) bean B instance every time bean A needs it. The following\n            example    shows   this  approach:\n\n            Java\n\n\n              //  a  class   that   uses   a  stateful    Command-style       class   to  perform    some   processing\n              package    fiona.apple;\n\n\n              //  Spring-API      imports\n              import    org.springframework.beans.BeansException;\n              import    org.springframework.context.ApplicationContext;\n              import    org.springframework.context.ApplicationContextAware;\n\n\n              public    class   CommandManager       implements     ApplicationContextAware          {\n\n\n                    private    ApplicationContext        applicationContext;\n\n\n                    public   Object    process(Map      commandState)      {\n                         //  grab   a  new   instance    of  the   appropriate     Command\n                         Command    command    =  createCommand();\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    protected     Command    createCommand()       {\n                         //  notice    the   Spring   API   dependency!\n                         return    this.applicationContext.getBean(\"command\",                 Command.class);\n                    }\n\n\n                    public   void   setApplicationContext(\n                               ApplicationContext        applicationContext)        throws    BeansException       {\n                         this.applicationContext          =  applicationContext;\n                    }\n              }\n\n            Kotlin\n\n\n              //  a  class   that   uses   a  stateful    Command-style       class   to  perform    some   processing\n              package    fiona.apple\n\n\n              //  Spring-API      imports\n              import    org.springframework.context.ApplicationContext\n              import    org.springframework.context.ApplicationContextAware\n\n\n              class    CommandManager      :  ApplicationContextAware          {\n\n\n                    private    lateinit    var   applicationContext:        ApplicationContext\n\n\n                    fun  process(commandState:          Map<*,   *>):   Any   {\n                         //  grab   a  new   instance    of  the   appropriate     Command\n                         val   command    =  createCommand()\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    //  notice    the  Spring    API  dependency!\n                    protected     fun  createCommand()       =\n                               applicationContext.getBean(\"command\",               Command::class.java)\n\n\n                    override    fun   setApplicationContext(applicationContext:                ApplicationContext)         {\n                         this.applicationContext          =  applicationContext\n                    }\n              }\n\n\n\n            The preceding is not desirable, because the business code is aware of and coupled to the Spring\n            Framework.      Method    Injection,   a somewhat      advanced     feature   of  the  Spring   IoC  container,   lets  you\n            handle   this use  case  cleanly.\n\n\n\n               You   can  read  more   about   the  motivation    for  Method    Injection   in this blog  entry.\n\n\n\n\n\n            Lookup   Method   Injection\n\n            Lookup    method    injection   is the  ability of  the  container   to  override   methods     on  container-managed\n            beans   and  return   the  lookup    result  for another    named     bean   in the  container.    The  lookup    typically\n            involves a prototype bean, as in the scenario described in the preceding section. The Spring\n            Framework      implements     this  method    injection   by  using  bytecode    generation    from   the  CGLIB    library\n            to dynamically     generate   a  subclass   that overrides    the  method.\n\n                                • For  this  dynamic    subclassing    to  work,   the  class that  the  Spring   bean   container\n                                  subclasses    cannot   be  final,  and   the  method    to  be  overridden     cannot   be  final,\n                                  either.\n\n                                • Unit-testing    a class  that  has   an  abstract   method     requires    you  to  subclass   the\n                                  class  yourself   and  to supply   a stub  implementation       of the  abstract   method.\n                               • Concrete    methods     are  also necessary     for component      scanning,    which    requires\n                                  concrete   classes   to pick  up.\n\n                                • A further key limitation is that lookup methods do not work with factory\n                                  methods and in particular not with @Bean methods in configuration classes,\n                                  since,  in  that  case, the  container    is not  in  charge   of  creating   the  instance   and\n                                  therefore   cannot    create  a runtime-generated        subclass   on  the fly.\n\n\n            In the case of the CommandManager class in the previous code snippet, the Spring container\n            dynamically     overrides    the implementation       of the  createCommand()      method.    The  CommandManager     class\n            does  not  have   any  Spring   dependencies,     as the  reworked     example    shows:\n\n\n            Java\n\n\n              package    fiona.apple;\n\n\n              //  no   more  Spring    imports!\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         //  grab   a  new   instance    of  the   appropriate     Command    interface\n                         Command    command    =  createCommand();\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    //  okay...    but  where    is  the  implementation       of  this   method?\n                    protected     abstract    Command    createCommand();\n              }\n\n            Kotlin\n\n\n              package    fiona.apple\n\n\n              //  no   more  Spring    imports!\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         //  grab   a  new   instance    of  the   appropriate     Command    interface\n                         val   command    =  createCommand()\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    //  okay...    but  where    is  the  implementation       of  this   method?\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            In the client class that contains the method to be injected (the CommandManager in this case), the\n            method    to be  injected  requires    a signature   of the  following    form:\n\n\n\n              <public|protected>        [abstract]      <return-type>      theMethodName(no-arguments);\n\n\n\n            If  the  method   is abstract,   the  dynamically-generated         subclass   implements      the  method.    Otherwise,\n            the dynamically-generated subclass overrides the concrete method defined in the original class.\n            Consider   the  following    example:\n\n\n\n              <!--   a  stateful    bean   deployed     as  a prototype     (non-singleton)       -->\n              <bean    id=\"myCommand\"      class=\"fiona.apple.AsyncCommand\"              scope=\"prototype\">\n                    <!--   inject   dependencies      here   as  required     -->\n              </bean>\n\n\n              <!--   commandProcessor        uses  statefulCommandHelper          -->\n              <bean    id=\"commandManager\"        class=\"fiona.apple.CommandManager\">\n                    <lookup-method      name=\"createCommand\"         bean=\"myCommand\"/>\n              </bean>\n\n\n\n            The bean identified as commandManager calls its own createCommand() method whenever it needs a\n            new   instance   of the  myCommand   bean.   You  must   be  careful  to deploy   the  myCommand    bean   as a prototype\n            if that is actually what is needed. If it is a singleton, the same instance of the myCommand bean is\n            returned   each   time.\n\n\n            Alternatively, within the annotation-based component model, you can declare a lookup method\n            through   the  @Lookup   annotation,    as the  following   example     shows:\n\n            Java\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         Command    command    =  createCommand();\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    @Lookup(\"myCommand\")\n                    protected     abstract    Command    createCommand();\n              }\n\n\n\n            Kotlin\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         val   command    =  createCommand()\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    @Lookup(\"myCommand\")\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            Or, more    idiomatically,   you   can  rely on  the  target  bean   getting   resolved   against   the  declared   return\n            type  of the lookup    method:\n\n\n            Java\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         Command    command    =  createCommand();\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    @Lookup\n                    protected     abstract    Command    createCommand();\n              }\n\n            Kotlin\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         val   command    =  createCommand()\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    @Lookup\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            Note that you should typically declare such annotated lookup methods with a concrete stub\n            implementation,      in order   for them    to be  compatible    with   Spring’s  component      scanning    rules  where\n            abstract classes get ignored by default. This limitation does not apply to explicitly registered or\n            explicitly  imported    bean   classes.\n\n\n                              Another way of accessing differently scoped target beans is an ObjectFactory/\n                              Provider   injection  point.  See  Scoped    Beans   as Dependencies.\n                 \n                              You       may        also      find       the       ServiceLocatorFactoryBean             (in      the\n                              org.springframework.beans.factory.config             package)    to be useful.\n\n\n\n            Arbitrary  Method   Replacement\n\n            A less useful form of method injection than lookup method injection is the ability to replace\n            arbitrary   methods     in a  managed     bean    with  another    method     implementation.       You  can   safely  skip\n            the rest  of this section   until you   actually  need   this functionality.\n\n\n            With XML-based configuration metadata, you can use the replaced-method element to replace an\n            existing  method     implementation       with   another,   for  a  deployed    bean.   Consider    the  following    class,\n            which   has  a method    called  computeValue     that  we  want   to override:\n\n\n            Java\n\n\n              public    class   MyValueCalculator        {\n\n\n                    public   String    computeValue(String         input)   {\n                         //  some   real   code...\n                    }\n\n\n                    //  some   other   methods...\n              }\n\n            Kotlin\n\n\n              class    MyValueCalculator       {\n\n\n                    fun  computeValue(input:         String):    String    {\n                         //  some   real   code...\n                    }\n\n\n                    //  some   other   methods...\n              }\n\n\n\n            A class that implements the org.springframework.beans.factory.support.MethodReplacer interface\n            provides   the  new   method    definition,   as the  following   example     shows:\n\n\n            Java\n\n\n              /**\n               *  meant    to  be  used   to  override    the   existing    computeValue(String)\n               *  implementation       in  MyValueCalculator\n               */\n              public    class   ReplacementComputeValue          implements     MethodReplacer       {\n\n\n                    public   Object    reimplement(Object        o,  Method    m,  Object[]    args)    throws   Throwable     {\n                         //  get   the  input    value,   work   with   it,   and  return    a computed     result\n                         String    input   =  (String)    args[0];\n                         ...\n                         return    ...;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              /**\n               *  meant    to  be  used   to  override    the   existing    computeValue(String)\n               *  implementation       in  MyValueCalculator\n               */\n              class    ReplacementComputeValue          : MethodReplacer       {\n\n\n                    override    fun   reimplement(obj:       Any,   method:    Method,    args:   Array<out     Any>):    Any  {\n                         //  get   the  input    value,   work   with   it,   and  return    a computed     result\n                         val   input   =  args[0]    as  String;\n                         ...\n                         return    ...;\n                    }\n              }\n\n\n\n            The  bean   definition    to deploy   the  original   class  and   specify   the  method    override    would    resemble\n            the following    example:\n\n              <bean    id=\"myValueCalculator\"         class=\"x.y.z.MyValueCalculator\">\n                    <!--   arbitrary    method    replacement      -->\n                    <replaced-method       name=\"computeValue\"         replacer=\"replacementComputeValue\">\n                         <arg-type>String</arg-type>\n                    </replaced-method>\n              </bean>\n\n\n              <bean    id=\"replacementComputeValue\"           class=\"a.b.c.ReplacementComputeValue\"/>\n\n\n\n            You  can   use  one   or more    <arg-type/>    elements     within   the  <replaced-method/>       element    to indicate\n            the method signature of the method being overridden. The signature for the arguments is\n            necessary only if the method is overloaded and multiple variants exist within the class. For\n            convenience,     the  type  string  for  an  argument     may   be  a  substring   of  the  fully qualified   type   name.\n            For example,    the  following    all  match  java.lang.String:\n\n\n\n              java.lang.String\n              String\n              Str\n\n\n\n            Because   the  number     of arguments     is often  enough     to distinguish   between     each  possible   choice,   this\n            shortcut can save a lot of typing, by letting you type only the shortest string that matches an\n            argument     type.\n\n            2.1.5.   Bean     Scopes\n\n            When    you   create   a bean   definition,   you   create   a recipe   for  creating   actual   instances    of the  class\n            defined   by  that  bean   definition.   The  idea  that  a bean   definition    is a recipe   is  important,   because   it\n            means   that,  as with   a class, you  can  create   many    object  instances   from   a single  recipe.\n\n\n            You  can  control   not  only  the  various   dependencies      and   configuration     values   that are  to  be plugged\n            into an object that is created from a particular bean definition but also control the scope of the\n            objects  created   from    a particular   bean   definition.   This   approach    is powerful     and  flexible,  because\n            you  can  choose    the scope   of  the objects   you  create   through    configuration    instead   of  having   to bake\n            in the  scope   of  an  object  at  the  Java  class  level.  Beans   can   be  defined   to  be  deployed    in  one  of  a\n            number     of scopes.   The  Spring    Framework      supports    six scopes,   four   of which    are  available   only  if\n            you  use  a web-aware      ApplicationContext.      You  can  also  create  a custom    scope.\n\n            The  following   table  describes    the supported     scopes:\n\n\n            Table 3.

This  single\n            instance   is stored   in a  cache   of such   singleton    beans,   and  all subsequent      requests   and   references\n            for that  named    bean   return   the  cached    object.  The  following    image   shows    how   the  singleton   scope\n            works:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n            Spring’s   concept   of  a singleton    bean   differs  from    the  singleton   pattern   as  defined    in the  Gang    of\n            Four  (GoF)   patterns    book.  The   GoF   singleton   hard-codes     the  scope   of  an  object  such   that  one  and\n\n            only  one  instance   of  a particular   class  is created   per  ClassLoader.     The  scope   of the  Spring   singleton\n            is  best  described  as being   per-container     and   per-bean.   This  means    that,  if  you  define one  bean   for  a\n            particular   class in  a single  Spring   container,   the  Spring   container    creates  one   and  only  one   instance\n            of the  class  defined   by  that  bean   definition.   The   singleton   scope   is the  default   scope   in Spring.   To\n            define  a bean   as  a singleton   in XML,   you   can  define  a bean   as  shown    in the  following   example:\n\n\n\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"/>\n\n\n              <!--   the   following    is   equivalent,     though    redundant    (singleton      scope   is  the  default)\n              -->\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"\n              scope=\"singleton\"/>\n\n\n\n\n            The  Prototype     Scope\n\n            The non-singleton prototype scope of bean deployment results in the creation of a new bean\n            instance every time a request for that specific bean is made. That is, the bean is injected into\n            another    bean   or  you  request    it through    a getBean()    method     call on  the  container.    As  a  rule,  you\n            should   use  the prototype    scope   for all stateful  beans   and   the singleton   scope   for  stateless  beans.\n\n\n            The  following   diagram     illustrates  the Spring   prototype    scope:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n            (A data   access  object   (DAO)   is not  typically   configured    as  a prototype,    because    a  typical  DAO    does\n            not hold   any  conversational     state. It was   easier  for us  to reuse  the  core  of the  singleton   diagram.)\n\n            The  following   example     defines   a bean   as a prototype    in XML:\n\n\n\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"\n              scope=\"prototype\"/>\n\n\n\n            In contrast   to the  other   scopes,  Spring   does   not  manage     the complete     lifecycle  of a prototype    bean.\n\n            The  container    instantiates,   configures,    and  otherwise     assembles    a  prototype    object  and   hands   it to\n            the client,  with   no  further   record   of that  prototype    instance.   Thus,   although    initialization   lifecycle\n            callback   methods    are  called  on  all objects   regardless    of scope,  in  the case  of  prototypes,    configured\n            destruction lifecycle callbacks are not called. The client code must clean up prototype-scoped\n            objects  and   release  expensive     resources    that  the  prototype    beans   hold.  To  get the  Spring   container\n            to release  resources    held  by  prototype-scoped      beans,   try  using  a custom    bean   post-processor,     which\n            holds  a reference    to beans   that  need   to be cleaned    up.\n\n\n            In some   respects,   the  Spring   container’s   role  in  regard   to a prototype-scoped       bean  is a  replacement\n            for the  Java  new  operator.    All lifecycle  management        past  that  point  must    be  handled    by  the  client.\n            (For details  on  the  lifecycle  of a bean   in the  Spring   container,   see  Lifecycle   Callbacks.)\n\n\n            Singleton    Beans   with   Prototype-bean       Dependencies\n\n            When you use singleton-scoped beans with dependencies on prototype beans, be aware that\n            dependencies     are  resolved    at instantiation    time.  Thus,   if  you dependency-inject      a  prototype-scoped\n            bean into a singleton-scoped bean, a new prototype bean is instantiated and then dependency-\n            injected  into  the  singleton   bean.   The  prototype    instance    is  the  sole  instance that  is ever  supplied    to\n            the singleton-scoped      bean.\n\n\n            However,    suppose    you   want   the  singleton-scoped      bean   to acquire   a  new   instance   of the  prototype-\n            scoped bean repeatedly at runtime. You cannot dependency-inject a prototype-scoped bean into\n            your   singleton     bean,    because    that   injection    occurs    only    once,   when     the   Spring    container\n            instantiates the singleton bean and resolves and injects its dependencies. If you need a new\n            instance   of a prototype    bean   at runtime    more   than   once,  see Method     Injection.\n\n\n            Request,    Session,   Application,     and   WebSocket      Scopes\n\n            The  request,   session,   application,    and   websocket   scopes   are   available   only  if you   use  a web-aware\n            Spring ApplicationContext implementation (such as XmlWebApplicationContext). If you use these\n            scopes    with   regular     Spring    IoC   containers,     such   as   the   ClassPathXmlApplicationContext,           an\n            IllegalStateException       that complains     about   an  unknown     bean   scope   is thrown.\n\n\n\n            Initial  Web Configuration\n\n            To support the scoping of beans at the request, session, application, and websocket levels (web-\n            scoped beans), some minor initial configuration is required before you define your beans. (This\n            initial setup  is not  required   for  the standard    scopes:   singleton   and   prototype.)\n\n\n            How   you  accomplish     this  initial setup  depends    on  your   particular   Servlet  environment.\n\n\n            If  you access  scoped    beans   within   Spring   Web    MVC,   in effect,  within   a request   that  is processed    by\n            the  Spring   DispatcherServlet,      no  special   setup   is necessary.   DispatcherServlet       already   exposes    all\n            relevant   state.\n\n\n            If  you use  a  Servlet   web   container,    with  requests    processed    outside   of  Spring’s   DispatcherServlet\n            (for     example,        when        using      JSF      or      Struts),     you       need       to     register      the\n            org.springframework.web.context.request.RequestContextListener ServletRequestListener. This can\n            be done    programmatically       by  using   the WebApplicationInitializer         interface.   Alternatively,    add  the\n            following   declaration    to your   web   application’s   web.xml   file:\n\n              <web-app>\n                    ...\n                    <listener>\n                         <listener-class>\n                               org.springframework.web.context.request.RequestContextListener\n                         </listener-class>\n                    </listener>\n                    ...\n              </web-app>\n\n\n\n            Alternatively,     if   there    are    issues     with    your     listener     setup,    consider      using    Spring’s\n            RequestContextFilter.        The    filter   mapping       depends      on   the    surrounding       web     application\n            configuration,    so you   have   to change    it  as  appropriate.  The  following    listing shows    the  filter part  of\n            a web   application:\n\n\n\n              <web-app>\n                    ...\n                    <filter>\n                         <filter-name>requestContextFilter</filter-name>\n                         <filter-class>org.springframework.web.filter.RequestContextFilter</filter-\n              class>\n                    </filter>\n                    <filter-mapping>\n                         <filter-name>requestContextFilter</filter-name>\n                         <url-pattern>/*</url-pattern>\n                    </filter-mapping>\n                    ...\n              </web-app>\n\n\n\n            DispatcherServlet,     RequestContextListener,        and   RequestContextFilter       all do  exactly   the  same   thing,\n            namely    bind  the  HTTP    request   object  to  the  Thread  that  is servicing   that  request.   This  makes    beans\n            that are  request-   and  session-scoped      available   further  down    the  call chain.\n\n\n\n            Request  scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"loginAction\"       class=\"com.something.LoginAction\"              scope=\"request\"/>\n\n\n\n            The  Spring   container    creates   a new   instance   of  the LoginAction     bean   by using   the  loginAction    bean\n            definition for each and every HTTP request. That is, the loginAction bean is scoped at the HTTP\n            request   level. You  can   change   the  internal   state of  the instance    that is created   as  much   as  you  want,\n            because other instances created from the same loginAction bean definition do not see these\n            changes in state. They are particular to an individual request. When the request completes\n            processing,   the  bean   that is scoped   to  the request   is discarded.\n\n\n            When    using  annotation-driven       components      or Java  configuration,     the  @RequestScope    annotation     can\n\n            be used   to assign  a  component     to the  request   scope.  The   following   example     shows   how   to do  so:\n\n\n            Java\n\n\n              @RequestScope\n              @Component\n              public    class   LoginAction      {\n                    //  ...\n              }\n\n\n\n            Kotlin\n\n\n              @RequestScope\n              @Component\n              class    LoginAction     {\n                    //  ...\n              }\n\n\n\n\n            Session  Scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\"/>\n\n\n\n            The   Spring     container     creates    a  new     instance    of   the   UserPreferences       bean    by   using    the\n            userPreferences bean definition for the lifetime of a single HTTP Session. In other words, the\n            userPreferences     bean   is effectively   scoped   at the  HTTP    Session   level. As  with   request-scoped     beans,\n            you  can  change    the  internal  state  of the  instance   that  is created   as much    as you   want,   knowing    that\n            other  HTTP    Session   instances    that  are  also  using  instances    created   from   the  same    userPreferences\n            bean  definition    do not  see  these  changes    in state,  because   they   are particular    to an  individual   HTTP\n            Session.  When     the  HTTP   Session   is eventually    discarded,    the  bean   that  is scoped   to  that  particular\n            HTTP   Session   is also discarded.\n\n\n            When using annotation-driven components or Java configuration, you can use the @SessionScope\n            annotation    to assign   a component      to the session   scope.\n\n\n            Java\n\n\n              @SessionScope\n              @Component\n              public    class   UserPreferences       {\n                    //  ...\n              }\n\n            Kotlin\n\n\n              @SessionScope\n              @Component\n              class    UserPreferences       {\n                    //  ...\n              }\n\n\n\n\n            Application  Scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"appPreferences\"        class=\"com.something.AppPreferences\"               scope=\"application\"/>\n\n\n\n            The  Spring   container    creates  a  new   instance   of the  AppPreferences     bean   by  using  the  appPreferences\n            bean  definition   once   for the  entire  web   application.    That  is, the appPreferences     bean   is scoped   at the\n            ServletContext     level  and  stored   as a  regular   ServletContext     attribute.  This  is somewhat      similar   to a\n            Spring  singleton    bean  but  differs  in two   important    ways:   It is  a singleton  per ServletContext,     not  per\n            Spring   ApplicationContext      (for  which   there   may   be  several   in any   given  web   application),    and   it  is\n            actually  exposed    and   therefore   visible  as a ServletContext     attribute.\n\n\n            When      using     annotation-driven        components         or   Java     configuration,      you     can    use    the\n            @ApplicationScope annotation to assign a component to the application scope. The following\n            example    shows   how    to do so:\n\n\n            Java\n\n\n              @ApplicationScope\n              @Component\n              public    class   AppPreferences       {\n                    //  ...\n              }\n\n\n\n            Kotlin\n\n\n              @ApplicationScope\n              @Component\n              class    AppPreferences      {\n                    //  ...\n              }\n\n\n\n\n            WebSocket    Scope\n\n            WebSocket     scope   is associated   with   the  lifecycle  of a WebSocket      session  and   applies   to STOMP     over\n            WebSocket     applications,   see  WebSocket     scope   for  more   details.\n\n            Scoped  Beans   as Dependencies\n\n            The  Spring   IoC  container     manages     not  only  the  instantiation    of  your   objects  (beans),   but  also  the\n            wiring   up  of collaborators     (or dependencies).      If  you want   to inject  (for  example)    an  HTTP    request-\n            scoped   bean   into  another    bean   of a  longer-lived    scope,  you   may   choose    to inject  an  AOP   proxy    in\n            place  of  the  scoped   bean.   That   is,  you need   to  inject  a proxy    object  that  exposes    the  same   public\n            interface as the scoped object but that can also retrieve the real target object from the relevant\n            scope  (such   as an  HTTP   request)   and   delegate   method    calls  onto  the  real object.\n\n\n                              You  may   also  use  <aop:scoped-proxy/>       between    beans   that  are  scoped   as  singleton,\n                              with  the  reference    then   going   through    an  intermediate     proxy    that  is serializable\n                              and  therefore   able  to  re-obtain   the target  singleton    bean  on  deserialization.\n\n\n                              When declaring <aop:scoped-proxy/> against a bean of scope prototype, every\n                              method    call on  the  shared    proxy   leads   to the  creation   of a  new   target  instance    to\n                              which   the  call is  then being  forwarded.\n\n                              Also, scoped    proxies   are  not  the only   way   to access  beans    from   shorter   scopes  in  a\n                              lifecycle-safe fashion. You may also declare your injection point (that is, the\n                             constructor    or setter  argument     or  autowired    field)  as ObjectFactory<MyTargetBean>,\n                              allowing   for  a  getObject()    call to  retrieve   the  current   instance    on  demand     every\n                              time  it  is  needed — without    holding    on to  the instance   or  storing  it separately.\n\n\n                              As an extended variant, you may declare ObjectProvider<MyTargetBean> which\n                              delivers    several     additional     access     variants,    including      getIfAvailable      and\n                              getIfUnique.\n\n\n                              The    JSR-330     variant     of   this    is   called    Provider     and     is   used    with     a\n                              Provider<MyTargetBean> declaration and a corresponding get() call for every\n                              retrieval  attempt.   See  here  for  more   details  on  JSR-330   overall.\n\n\n            The  configuration     in  the following    example     is only  one   line, but  it is important    to  understand     the\n            “why”   as well  as  the “how”    behind   it:\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:aop=\"http://www.springframework.org/schema/aop\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\n                         http://www.springframework.org/schema/aop\n                         https://www.springframework.org/schema/aop/spring-aop.xsd\">\n\n\n                    <!--   an  HTTP   Session-scoped      bean   exposed    as  a  proxy   -->\n                    <bean   id=\"userPreferences\"         class=\"com.something.UserPreferences\"               scope=\"session\">\n                         <!--   instructs     the  container     to  proxy    the  surrounding      bean  -->\n                         <aop:scoped-proxy/>         ①\n                    </bean>\n\n\n                    <!--   a singleton-scoped        bean   injected    with   a  proxy   to  the   above   bean   -->\n                    <bean   id=\"userService\"       class=\"com.something.SimpleUserService\">\n                         <!--   a  reference     to  the  proxied    userPreferences       bean   -->\n                         <property     name=\"userPreferences\"          ref=\"userPreferences\"/>\n                    </bean>\n              </beans>\n\n\n            ① The    line that  defines   the proxy.\n\n            To create   such  a proxy,   you  insert  a child  <aop:scoped-proxy/>       element    into  a scoped   bean   definition\n            (see Choosing the Type of Proxy to Create and XML Schema-based configuration). Why do\n            definitions   of beans   scoped   at  the request,   session   and  custom-scope      levels  require   the  <aop:scoped-\n            proxy/> element? Consider the following singleton bean definition and contrast it with what you\n            need to define for the aforementioned scopes (note that the following userPreferences bean\n            definition   as it  stands is incomplete):\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\"/>\n\n\n              <bean    id=\"userManager\"       class=\"com.something.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n            In the  preceding    example,    the  singleton   bean   (userManager)    is injected   with  a  reference   to  the HTTP\n            Session-scoped bean (userPreferences). The salient point here is that the userManager bean is a\n            singleton:   it  is  instantiated exactly   once   per  container,   and   its dependencies      (in this case   only  one,\n            the userPreferences bean) are also injected only once. This means that the userManager bean\n            operates   only  on  the  exact  same   userPreferences      object  (that  is,  the  one  with which   it was  originally\n            injected).\n\n            This  is not  the  behavior    you   want   when    injecting   a  shorter-lived    scoped    bean   into  a longer-lived\n            scoped   bean   (for  example,    injecting   an   HTTP   Session-scoped      collaborating     bean   as  a dependency\n            into singleton    bean).  Rather,   you   need   a single  userManager     object,  and,  for  the lifetime   of an  HTTP\n            Session,  you   need   a userPreferences      object  that  is specific  to the  HTTP    Session.   Thus,  the  container\n\n            creates  an  object   that  exposes   the  exact   same   public   interface   as  the  UserPreferences     class  (ideally\n            an  object  that  is a UserPreferences      instance),   which    can  fetch  the  real  UserPreferences      object  from\n            the scoping mechanism (HTTP request, Session, and so forth). The container injects this proxy\n            object  into the  userManager    bean,   which   is unaware     that  this UserPreferences     reference    is a proxy.   In\n            this  example,     when     a   UserManager     instance     invokes    a   method     on   the   dependency-injected\n            UserPreferences     object,  it is actually   invoking    a  method     on  the  proxy.   The  proxy    then  fetches   the\n            real UserPreferences object from (in this case) the HTTP Session and delegates the method\n            invocation    onto  the  retrieved   real UserPreferences      object.\n\n            Thus, you need the following (correct and complete) configuration when injecting request- and\n            session-scoped     beans   into collaborating     objects,  as the  following   example    shows:\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\">\n                    <aop:scoped-proxy/>\n              </bean>\n\n\n              <bean    id=\"userManager\"       class=\"com.something.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n\n            Choosing    the  Type   of  Proxy   to  Create\n\n            By default, when the Spring container creates a proxy for a bean that is marked up with the\n            <aop:scoped-proxy/>      element,    a CGLIB-based     class  proxy   is created.\n\n\n                              CGLIB   proxies   intercept    only  public   method    calls! Do   not  call non-public    methods\n                             on such   a proxy.   They  are  not  delegated    to the  actual  scoped   target  object.\n\n\n            Alternatively, you can configure the Spring container to create standard JDK interface-based\n            proxies   for such   scoped   beans,   by  specifying   false   for the  value   of the  proxy-target-class      attribute\n            of the  <aop:scoped-proxy/>      element.    Using   JDK  interface-based      proxies   means    that  you  do  not  need\n            additional   libraries   in your   application    classpath    to affect  such   proxying.    However,     it also  means\n            that the  class  of  the  scoped   bean   must    implement     at  least one   interface   and   that  all collaborators\n            into which    the  scoped    bean   is injected   must   reference    the  bean   through    one  of  its interfaces.   The\n            following   example    shows    a proxy   based   on  an  interface:\n\n\n\n              <!--   DefaultUserPreferences          implements     the  UserPreferences       interface     -->\n              <bean    id=\"userPreferences\"        class=\"com.stuff.DefaultUserPreferences\"                 scope=\"session\">\n                    <aop:scoped-proxy        proxy-target-class=\"false\"/>\n              </bean>\n\n\n              <bean    id=\"userManager\"       class=\"com.stuff.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n            For   more    detailed    information      about    choosing     class-based     or  interface-based      proxying,     see\n            Proxying    Mechanisms.\n\n            Custom    Scopes\n\n            The bean scoping mechanism is extensible. You can define your own scopes or even redefine\n            existing  scopes,   although    the  latter is considered     bad  practice   and   you  cannot    override   the  built-in\n            singleton   and   prototype   scopes.\n\n\n\n            Creating  a Custom   Scope\n\n            To   integrate    your    custom     scopes    into   the   Spring    container,     you    need    to   implement      the\n            org.springframework.beans.factory.config.Scope               interface,  which    is  described  in  this section.  For  an\n            idea  of how    to implement     your   own    scopes,  see  the  Scope   implementations       that  are  supplied    with\n            the Spring Framework itself and the Scope javadoc, which explains the methods you need to\n            implement     in more   detail.\n\n\n            The  Scope   interface   has  four  methods     to  get objects   from   the  scope,   remove    them    from   the  scope,\n            and  let them   be  destroyed.\n\n\n            The session scope implementation, for example, returns the session-scoped bean (if it does not\n            exist, the  method    returns   a new   instance   of  the bean,   after  having   bound    it  to  the  session  for  future\n            reference).   The  following    method    returns   the  object  from   the underlying     scope:\n\n\n            Java\n\n\n              Object    get(String     name,   ObjectFactory<?>        objectFactory)\n\n\n\n            Kotlin\n\n\n              fun   get(name:     String,    objectFactory:      ObjectFactory<*>):        Any\n\n\n\n            The session scope implementation, for example, removes the session-scoped bean from the\n            underlying    session.   The   object  should    be  returned,    but  you  can   return   null  if the  object   with  the\n            specified  name    is not  found.  The   following   method     removes    the  object  from   the underlying     scope:\n\n\n            Java\n\n\n              Object    remove(String      name)\n\n\n\n            Kotlin\n\n\n              fun   remove(name:      String):    Any\n\n\n\n            The following method registers a callback that the scope should invoke when it is destroyed or\n            when   the  specified   object  in the  scope   is  destroyed:\n\n\n            Java\n\n\n              void   registerDestructionCallback(String              name,    Runnable    destructionCallback)\n\n            Kotlin\n\n\n              fun   registerDestructionCallback(name:              String,    destructionCallback:        Runnable)\n\n\n\n            See the  javadoc   or  a Spring   scope   implementation      for  more   information     on  destruction    callbacks.\n\n            The  following   method     obtains   the conversation     identifier   for the  underlying    scope:\n\n\n            Java\n\n\n              String    getConversationId()\n\n\n\n            Kotlin\n\n\n              fun   getConversationId():         String\n\n\n\n            This  identifier  is different   for  each   scope.  For  a  session   scoped   implementation,       this identifier   can\n            be the  session   identifier.\n\n\n\n            Using a Custom    Scope\n\n            After  you  write   and   test one  or  more   custom    Scope   implementations,       you  need   to make    the  Spring\n            container   aware    of your   new   scopes.   The  following    method    is the  central   method    to register   a new\n            Scope  with  the  Spring   container:\n\n\n            Java\n\n\n              void   registerScope(String         scopeName,     Scope   scope);\n\n\n\n            Kotlin\n\n\n              fun   registerScope(scopeName:          String,    scope:    Scope)\n\n\n\n            This  method     is declared   on   the  ConfigurableBeanFactory        interface,   which    is available   through    the\n            BeanFactory property on most of the concrete ApplicationContext implementations that ship with\n            Spring.\n\n\n            The  first argument      to the  registerScope(..)       method    is the  unique    name    associated    with   a  scope.\n            Examples of such names in the Spring container itself are singleton and prototype. The second\n            argument      to   the   registerScope(..)        method      is   an   actual    instance     of   the   custom      Scope\n            implementation      that  you  wish   to register  and   use.\n\n            Suppose that you write your custom Scope implementation, and then register it as shown in the\n            next  example.\n\n                              The  next  example     uses  SimpleThreadScope,      which   is included    with  Spring   but  is not\n                             registered by default. The instructions would be the same for your own custom\n                              Scope  implementations.\n\n\n            Java\n\n\n              Scope    threadScope     =  new  SimpleThreadScope();\n              beanFactory.registerScope(\"thread\",               threadScope);\n\n\n\n            Kotlin\n\n\n              val   threadScope     =  SimpleThreadScope()\n              beanFactory.registerScope(\"thread\",               threadScope)\n\n\n\n            You can then create bean definitions that adhere to the scoping rules of your custom Scope, as\n            follows:\n\n\n\n              <bean    id=\"...\"    class=\"...\"     scope=\"thread\">\n\n\n\n            With  a  custom   Scope   implementation,      you  are  not  limited   to programmatic      registration    of the  scope.\n            You  can  also  do  the  Scope  registration   declaratively,    by  using  the  CustomScopeConfigurer       class,  as the\n            following   example    shows:\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:aop=\"http://www.springframework.org/schema/aop\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\n                         http://www.springframework.org/schema/aop\n                         https://www.springframework.org/schema/aop/spring-aop.xsd\">\n\n\n                    <bean   class=\"org.springframework.beans.factory.config.CustomScopeConfigurer\">\n                         <property     name=\"scopes\">\n                               <map>\n                                    <entry    key=\"thread\">\n                                          <bean\n              class=\"org.springframework.context.support.SimpleThreadScope\"/>\n                                    </entry>\n                               </map>\n                         </property>\n                    </bean>\n\n\n                    <bean   id=\"thing2\"      class=\"x.y.Thing2\"        scope=\"thread\">\n                         <property     name=\"name\"      value=\"Rick\"/>\n                         <aop:scoped-proxy/>\n                    </bean>\n\n\n                    <bean   id=\"thing1\"      class=\"x.y.Thing1\">\n                         <property     name=\"thing2\"      ref=\"thing2\"/>\n                    </bean>\n\n\n              </beans>\n\n\n\n\n                              When    you  place   <aop:scoped-proxy/>       within   a <bean>   declaration    for a  FactoryBean\n                             implementation,      it is the factory   bean   itself that  is scoped,   not  the  object  returned\n                              from  getObject().\n\n\n            2.1.6.   Customizing          the   Nature       of  a Bean\n\n            The  Spring   Framework       provides    a number     of  interfaces   you   can  use  to  customize    the  nature   of  a\n            bean.  This  section   groups   them   as follows:\n\n              • Lifecycle   Callbacks\n\n              • ApplicationContextAware        and  BeanNameAware\n\n              • Other   Aware  Interfaces\n\n\n            Lifecycle   Callbacks\n\n            To  interact  with   the  container’s    management       of  the bean    lifecycle,  you  can   implement     the  Spring\n            InitializingBean and DisposableBean interfaces. The container calls afterPropertiesSet() for the\n\n            former   and   destroy()    for the  latter  to let the  bean   perform     certain  actions   upon    initialization  and\n            destruction    of your  beans.\n\n\n                              The  JSR-250   @PostConstruct      and  @PreDestroy     annotations     are  generally   considered\n                              best practice   for receiving    lifecycle  callbacks   in a modern     Spring   application.   Using\n                              these annotations means that your beans are not coupled to Spring-specific\n                             interfaces.  For  details,  see Using   @PostConstruct     and   @PreDestroy.\n\n\n                              If you do not want to use the JSR-250 annotations but you still want to remove\n                              coupling,   consider   init-method    and   destroy-method     bean   definition   metadata.\n\n\n            Internally,  the  Spring   Framework       uses  BeanPostProcessor       implementations       to process   any   callback\n            interfaces it can find and call the appropriate methods. If you need custom features or other\n            lifecycle  behavior    Spring  does   not  by default   offer, you   can  implement     a BeanPostProcessor      yourself.\n            For more    information,    see  Container    Extension    Points.\n\n\n            In addition to the initialization and destruction callbacks, Spring-managed objects may also\n            implement     the  Lifecycle   interface   so  that those   objects  can  participate    in the  startup  and   shutdown\n            process,  as  driven   by the  container’s    own   lifecycle.\n\n\n            The  lifecycle  callback   interfaces   are  described    in this section.\n\n\n\n            Initialization Callbacks\n\n            The     org.springframework.beans.factory.InitializingBean                   interface     lets    a    bean      perform\n            initialization    work    after   the   container     has   set   all  necessary     properties     on   the   bean.    The\n            InitializingBean     interface   specifies   a single  method:\n\n\n\n              void   afterPropertiesSet()         throws    Exception;\n\n\n\n            We  recommend       that  you  do  not  use  the InitializingBean      interface,   because   it unnecessarily     couples\n            the code to Spring. Alternatively, we suggest using the @PostConstruct annotation or specifying a\n            POJO   initialization  method.    In  the  case  of XML-based      configuration    metadata,    you   can  use  the  init-\n            method attribute to specify the name of the method that has a void no-argument signature. With\n            Java  configuration,    you   can  use  the  initMethod    attribute   of @Bean.  See  Receiving    Lifecycle   Callbacks.\n            Consider   the  following    example:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.ExampleBean\"            init-method=\"init\"/>\n\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    public   void   init()    {\n                         //  do   some  initialization       work\n                    }\n              }\n\n            Kotlin\n\n\n              class    ExampleBean     {\n\n\n                    fun  init()    {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            The  preceding    example     has  almost   exactly  the  same   effect  as the  following    example    (which   consists\n            of two  listings):\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.AnotherExampleBean\"/>\n\n\n\n            Java\n\n\n              public    class   AnotherExampleBean        implements     InitializingBean        {\n\n\n                    @Override\n                    public   void   afterPropertiesSet()         {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    AnotherExampleBean        : InitializingBean        {\n\n\n                    override    fun   afterPropertiesSet()         {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            However,    the  first of the  two  preceding    examples     does  not  couple   the  code  to Spring.\n\n\n\n            Destruction   Callbacks\n\n            Implementing the org.springframework.beans.factory.DisposableBean interface lets a bean get a\n            callback   when    the  container    that  contains   it is destroyed.    The   DisposableBean     interface   specifies   a\n            single  method:\n\n\n\n              void   destroy()     throws    Exception;\n\n\n\n            We  recommend       that  you   do  not  use  the DisposableBean      callback   interface,  because    it unnecessarily\n            couples   the  code  to Spring.   Alternatively,    we  suggest   using   the @PreDestroy     annotation    or  specifying\n            a generic   method     that  is supported     by  bean   definitions.   With   XML-based      configuration     metadata,\n            you  can   use  the  destroy-method     attribute   on  the  <bean/>.   With   Java  configuration,     you   can  use  the\n\n            destroyMethod      attribute    of  @Bean.   See    Receiving     Lifecycle    Callbacks.    Consider     the   following\n            definition:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.ExampleBean\"            destroy-method=\"cleanup\"/>\n\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    public   void   cleanup()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     {\n\n\n                    fun  cleanup()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            The  preceding    definition   has  almost   exactly   the same    effect as  the following    definition:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.AnotherExampleBean\"/>\n\n\n\n            Java\n\n\n              public    class   AnotherExampleBean        implements     DisposableBean       {\n\n\n                    @Override\n                    public   void   destroy()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    AnotherExampleBean        : DisposableBean       {\n\n\n                    override    fun   destroy()    {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n            However,    the  first of the  two  preceding    definitions   does   not  couple   the code   to Spring.\n\n\n                              You  can  assign   the destroy-method     attribute   of a <bean>   element    a special  (inferred)\n                              value, which instructs Spring to automatically detect a public close or shutdown\n                              method       on     the    specific     bean      class.     (Any     class     that    implements\n                              java.lang.AutoCloseable or java.io.Closeable would therefore match.) You can\n                             also  set this  special  (inferred)    value   on  the  default-destroy-method        attribute   of  a\n                              <beans> element to apply this behavior to an entire set of beans (see Default\n                              Initialization  and   Destroy   Methods).    Note   that this  is  the  default behavior   with   Java\n                              configuration.\n\n\n\n            Default  Initialization and  Destroy  Methods\n\n            When you write initialization and destroy method callbacks that do not use the Spring-specific\n            InitializingBean      and  DisposableBean      callback   interfaces,   you   typically   write  methods     with   names\n            such as init(), initialize(), dispose(), and so on. Ideally, the names of such lifecycle callback\n            methods    are  standardized      across  a  project  so  that  all developers    use   the same    method    names    and\n            ensure   consistency.\n\n\n            You can configure the Spring container to “look” for named initialization and destroy callback\n            method names on every bean. This means that you, as an application developer, can write your\n            application    classes  and   use  an  initialization   callback   called  init(),   without   having    to configure    an\n            init-method=\"init\"      attribute   with  each   bean   definition.   The  Spring    IoC container    calls  that  method\n            when   the  bean   is created   (and  in accordance     with   the standard    lifecycle  callback   contract   described\n            previously).   This  feature   also enforces    a consistent   naming     convention    for  initialization   and  destroy\n            method    callbacks.\n\n            Suppose that your initialization callback methods are named init() and your destroy callback\n            methods    are  named    destroy().   Your   class then   resembles    the  class  in the following    example:\n\n\n            Java\n\n\n              public    class   DefaultBlogService        implements     BlogService      {\n\n\n                    private    BlogDao    blogDao;\n\n\n                    public   void   setBlogDao(BlogDao        blogDao)     {\n                         this.blogDao      =  blogDao;\n                    }\n\n\n                    //  this   is  (unsurprisingly)       the   initialization      callback     method\n                    public   void   init()    {\n                         if  (this.blogDao       ==  null)   {\n                               throw   new   IllegalStateException(\"The           [blogDao]    property     must   be  set.\");\n                         }\n                    }\n              }\n\n            Kotlin\n\n\n              class    DefaultBlogService        : BlogService      {\n\n\n                    private    var  blogDao:     BlogDao?    =  null\n\n\n                    //  this   is  (unsurprisingly)       the   initialization      callback     method\n                    fun  init()    {\n                         if  (blogDao     ==  null)   {\n                               throw   IllegalStateException(\"The           [blogDao]     property    must   be  set.\")\n                         }\n                    }\n              }\n\n\n\n            You  could  then   use  that class  in a bean   resembling     the  following:\n\n\n\n              <beans    default-init-method=\"init\">\n\n\n                    <bean   id=\"blogService\"       class=\"com.something.DefaultBlogService\">\n                         <property     name=\"blogDao\"       ref=\"blogDao\"      />\n                    </bean>\n\n\n              </beans>\n\n\n\n            The  presence    of the  default-init-method      attribute   on  the  top-level  <beans/>    element   attribute   causes\n            the  Spring   IoC  container    to recognize     a method     called  init  on  the  bean    class  as the  initialization\n            method    callback.   When    a  bean   is  created  and  assembled,     if the bean    class has   such  a  method,    it  is\n            invoked   at the  appropriate     time.\n\n\n            You can configure destroy method callbacks similarly (in XML, that is) by using the default-\n            destroy-method     attribute  on  the  top-level  <beans/>    element.\n\n\n            Where    existing   bean   classes   already   have   callback    methods    that  are   named    at  variance    with  the\n            convention,    you   can  override   the  default   by  specifying   (in  XML,   that  is) the method     name    by using\n            the init-method    and   destroy-method     attributes   of the  <bean/>  itself.\n\n\n            The  Spring   container    guarantees    that  a configured    initialization   callback   is called  immediately     after\n            a bean   is supplied   with   all dependencies.     Thus,   the  initialization  callback    is  called on  the raw   bean\n            reference,   which   means    that  AOP   interceptors    and   so forth  are  not  yet  applied   to the  bean.  A  target\n            bean  is fully  created   first and  then  an  AOP   proxy   (for  example)    with  its interceptor    chain   is  applied.\n            If  the  target bean   and  the  proxy    are  defined   separately,   your   code   can  even   interact   with  the  raw\n            target  bean,   bypassing    the  proxy.   Hence,   it would    be  inconsistent    to  apply   the  interceptors    to the\n            init method, because doing so would couple the lifecycle of the target bean to its proxy or\n            interceptors and leave strange semantics when your code interacts directly with the raw target\n            bean."

Spring              Framework                         Overview\n\n\n            Spring makes it easy to create Java enterprise applications. It provides everything you need to\n            embrace    the  Java   language    in  an  enterprise    environment,      with   support   for  Groovy    and   Kotlin   as\n            alternative languages on the JVM, and with the flexibility to create many kinds of architectures\n            depending     on  an  application’s    needs.  As  of  Spring   Framework      5.1, Spring   requires    JDK  8+  (Java  SE\n            8+) and provides out-of-the-box support for JDK 11 LTS. Java SE 8 update 60 is suggested as the\n            minimum      patch  release   for Java  8, but  it is  generally  recommended       to  use a  recent  patch   release.\n\n            Spring  supports    a wide   range   of application    scenarios.   In  a large  enterprise,   applications    often  exist\n            for a  long  time   and   have   to run   on  a  JDK  and   application    server   whose    upgrade     cycle  is beyond\n            developer    control.   Others   may    run  as  a single   jar with   the  server   embedded,      possibly   in  a cloud\n            environment.      Yet others   may    be standalone     applications    (such   as  batch   or integration    workloads)\n            that do  not  need   a server.\n\n\n            Spring  is open   source.   It  has  a large  and active  community      that  provides   continuous     feedback    based\n            on a  diverse   range  of  real-world   use  cases.  This  has  helped    Spring  to  successfully   evolve   over  a  very\n            long  time.\n\n            1.1.    What          We      Mean          by    \"Spring\"\n\n\n            The  term   \"Spring\"   means    different   things  in  different   contexts.  It can  be  used   to refer  to the  Spring\n            Framework      project   itself,  which  is where    it  all  started.  Over time,  other  Spring   projects   have   been\n            built on  top  of  the Spring    Framework.      Most   often,  when    people   say  \"Spring\",   they  mean    the  entire\n            family  of  projects.  This  reference    documentation       focuses   on  the foundation:     the  Spring   Framework\n            itself.\n\n\n            The  Spring   Framework      is divided   into  modules.    Applications     can  choose   which    modules    they  need.\n            At the heart are the modules of the core container, including a configuration model and a\n            dependency injection mechanism. Beyond that, the Spring Framework provides foundational\n            support    for   different    application     architectures,     including    messaging,      transactional     data   and\n            persistence, and web. It also includes the Servlet-based Spring MVC web framework and, in\n            parallel, the  Spring   WebFlux     reactive   web   framework.\n\n\n            A note about modules: Spring’s framework jars allow for deployment to JDK 9’s module path\n            (\"Jigsaw\"). For use in Jigsaw-enabled applications, the Spring Framework 5 jars come with\n            \"Automatic-Module-Name\" manifest entries which define stable language-level module names\n            (\"spring.core\",   \"spring.context\",     etc.) independent     from    jar artifact  names    (the  jars follow   the  same\n            naming    pattern   with   \"-\" instead   of  \".\",  e.g.  \"spring-core\"  and   \"spring-context\").    Of  course,   Spring’s\n            framework     jars  keep  working    fine  on  the  classpath   on  both  JDK  8  and  9+.\n\n            1.2.    History            of   Spring          and       the      Spring          Framework\n\n\n            Spring came into being in 2003 as a response to the complexity of the early J2EE specifications.\n            While   some    consider   Java   EE  and   its modern-day      successor    Jakarta   EE  to  be  in  competition     with\n            Spring, they are in fact complementary. The Spring programming model does not embrace the\n            Jakarta    EE   platform      specification;    rather,    it  integrates     with    carefully    selected    individual\n\n            specifications   from   the  traditional   EE  umbrella:\n\n\n              • Servlet  API   (JSR 340)\n\n              • WebSocket     API  (JSR  356)\n\n              • Concurrency      Utilities (JSR  236)\n\n              • JSON   Binding    API  (JSR 367)\n\n              • Bean   Validation   (JSR  303)\n\n              • JPA  (JSR  338)\n\n              • JMS   (JSR 914)\n\n              • as well  as  JTA/JCA   setups  for  transaction    coordination,    if necessary.\n\n\n            The  Spring   Framework      also  supports    the Dependency       Injection   (JSR 330)  and   Common      Annotations\n            (JSR 250) specifications, which application developers may choose to use instead of the Spring-\n            specific  mechanisms      provided     by the  Spring   Framework.       Originally,  those   were   based   on  common\n            javax  packages.\n\n            As  of Spring   Framework       6.0, Spring   has  been   upgraded     to  the Jakarta   EE   9 level  (e.g. Servlet   5.0+,\n            JPA  3.0+), based    on  the  jakarta   namespace      instead   of the  traditional   javax   packages.    With   EE  9  as\n            the  minimum      and   EE  10  supported     already,   Spring   is prepared     to provide    out-of-the-box     support\n            for the further evolution of the Jakarta EE APIs. Spring Framework 6.0 is fully compatible with\n            Tomcat   10.1,  Jetty 11  and  Undertow     2.3  as web   servers,   and  also  with  Hibernate    ORM    6.1.\n\n\n            Over   time,  the role  of  Java/Jakarta    EE  in application    development      has  evolved.    In the  early  days   of\n            J2EE  and   Spring,  applications    were   created   to  be deployed     to an  application    server.  Today,   with  the\n            help  of Spring   Boot,   applications    are  created   in a  devops-   and   cloud-friendly     way,  with   the  Servlet\n            container   embedded      and   trivial  to change.   As  of  Spring   Framework      5, a  WebFlux     application    does\n            not  even   use  the  Servlet   API  directly   and   can  run   on  servers   (such   as  Netty)  that  are  not   Servlet\n            containers.\n\n\n            Spring  continues    to  innovate   and   to evolve.  Beyond     the Spring   Framework,      there  are  other   projects,\n            such as Spring Boot, Spring Security, Spring Data, Spring Cloud, Spring Batch, among others. It’s\n            important to remember that each project has its own source code repository, issue tracker, and\n            release  cadence.    See  spring.io/projects    for the  complete    list of Spring   projects.\n\n            1.3.    Design           Philosophy\n\n\n            When you learn about a framework, it’s important to know not only what it does but what\n            principles   it  follows. Here  are  the  guiding   principles   of the  Spring   Framework:\n\n\n              • Provide choice at every level. Spring lets you defer design decisions as late as possible. For\n                example, you can switch persistence providers through configuration without changing your\n                code.  The   same   is true  for  many   other   infrastructure     concerns    and  integration    with  third-party\n                APIs.\n\n              • Accommodate diverse perspectives. Spring embraces flexibility and is not opinionated about\n                how things should be done. It supports a wide range of application needs with different\n                perspectives.\n\n              • Maintain strong backward compatibility. Spring’s evolution has been carefully managed to\n                force  few   breaking    changes    between    versions.   Spring    supports   a  carefully   chosen   range   of  JDK\n                versions and third-party libraries to facilitate maintenance of applications and libraries that\n                depend    on  Spring.\n\n              • Care   about  API   design.  The  Spring   team   puts   a lot of thought   and   time  into  making    APIs  that  are\n                intuitive  and   that  hold  up  across  many    versions   and   many    years.\n\n              • Set high standards for code quality. The Spring Framework puts a strong emphasis on\n                meaningful,     current,   and   accurate    javadoc.   It is one   of very   few  projects   that  can   claim   clean\n                code   structure   with  no  circular   dependencies     between     packages.\n\n            1.4.    Feedback               and       Contributions\n\n\n            For how-to questions or diagnosing or debugging issues, we suggest using Stack Overflow. Click\n            here  for  a list of the  suggested    tags  to use  on  Stack   Overflow.    If  you’re fairly  certain   that there   is a\n            problem    in the  Spring   Framework      or would    like to suggest   a feature,   please  use  the  GitHub    Issues.\n\n            If you have a solution in mind or a suggested fix, you can submit a pull request on Github.\n            However,    please   keep   in mind    that, for  all but  the  most   trivial issues,  we  expect   a  ticket to  be  filed\n            in the issue  tracker,   where   discussions    take  place  and   leave  a record   for  future  reference.\n\n\n            For more    details  see the  guidelines    at the CONTRIBUTING,         top-level  project  page.\n\n            1.5.    Getting           Started\n\n\n            If  you are  just getting   started   with  Spring,   you  may    want   to begin   using   the  Spring   Framework      by\n            creating a Spring Boot-based application. Spring Boot provides a quick (and opinionated) way to\n            create a production-ready Spring-based application. It is based on the Spring Framework, favors\n            convention    over   configuration,    and  is designed    to get  you  up  and  running    as  quickly  as  possible.\n\n\n            You  can  use  start.spring.io    to generate    a basic  project   or follow   one  of  the  \"Getting   Started\"  guides,\n            such as Getting Started Building a RESTful Web Service. As well as being easier to digest, these\n            guides   are  very   task  focused,   and   most   of them    are  based   on   Spring   Boot.  They   also   cover   other\n            projects from the Spring portfolio that you might want to consider when solving a particular\n            problem.\n\n            Chapter                2.    Core           Technologies\n\n\n            This  part  of the  reference    documentation       covers   all  the  technologies   that  are  absolutely   integral   to\n            the Spring   Framework.\n\n\n            Foremost    amongst    these   is  the  Spring Framework’s      Inversion    of Control   (IoC)  container.   A  thorough\n            treatment    of the  Spring   Framework’s      IoC  container    is closely  followed    by  comprehensive       coverage\n            of Spring’s   Aspect-Oriented      Programming        (AOP)   technologies.    The   Spring   Framework       has  its own\n            AOP framework, which is conceptually easy to understand and which successfully addresses the\n            80%   sweet  spot  of AOP   requirements      in Java   enterprise   programming.\n\n\n            Coverage of Spring’s integration with AspectJ (currently the richest — in terms of features — and\n            certainly  most   mature    AOP   implementation       in the  Java  enterprise   space)   is also provided.\n\n\n            AOT processing can be used to optimize your application ahead-of-time. It is typically used for\n            native  image   deployment      using  GraalVM.\n\n            2.1.    The       IoC      Container\n\n\n            This  chapter   covers   Spring’s  Inversion    of Control   (IoC)  container.\n\n\n            2.1.1.   Introduction          to  the   Spring      IoC   Container        and    Beans\n\n            This chapter covers the Spring Framework implementation of the Inversion of Control (IoC)\n            principle. IoC is also known as dependency injection (DI). It is a process whereby objects define\n            their dependencies      (that  is, the other   objects   they  work   with)   only  through    constructor    arguments,\n            arguments to a factory method, or properties that are set on the object instance after it is\n            constructed or returned from a factory method. The container then injects those dependencies\n            when   it creates   the  bean.  This   process   is fundamentally      the  inverse   (hence   the  name,    Inversion    of\n            Control) of the bean itself controlling the instantiation or location of its dependencies by using\n            direct  construction    of classes  or  a mechanism      such   as the  Service  Locator    pattern.\n\n\n            The  org.springframework.beans         and   org.springframework.context         packages     are  the  basis  for  Spring\n            Framework’s       IoC   container.     The   BeanFactory      interface    provides     an   advanced      configuration\n            mechanism capable of managing any type of object. ApplicationContext is a sub-interface of\n            BeanFactory.   It adds:\n\n\n              • Easier   integration   with  Spring’s   AOP   features\n\n              • Message    resource    handling    (for use  in internationalization)\n\n              • Event   publication\n\n              • Application-layer       specific    contexts    such     as  the    WebApplicationContext         for   use   in   web\n                applications.\n\n\n            In short, the BeanFactory provides the configuration framework and basic functionality, and the\n            ApplicationContext       adds    more     enterprise-specific      functionality.     The    ApplicationContext        is  a\n            complete superset of the BeanFactory and is used exclusively in this chapter in descriptions of\n            Spring’s    IoC   container.     For    more     information      on    using    the   BeanFactory      instead    of   the\n\n            ApplicationContext,      see  the  section  covering    the BeanFactory    API.\n\n\n            In Spring, the objects that form the backbone of your application and that are managed by the\n            Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and\n            managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your\n            application.   Beans,   and   the dependencies      among     them,   are  reflected   in the  configuration    metadata\n            used  by  a container.\n\n\n            2.1.2.   Container        Overview\n\n            The  org.springframework.context.ApplicationContext                interface   represents    the  Spring   IoC  container\n            and  is responsible     for instantiating,    configuring,    and   assembling     the  beans.   The  container    gets  its\n            instructions on what objects to instantiate, configure, and assemble by reading configuration\n            metadata.    The  configuration     metadata     is  represented   in  XML,   Java  annotations,    or  Java  code.  It lets\n            you express the objects that compose your application and the rich interdependencies between\n            those  objects.\n\n\n            Several implementations of the ApplicationContext interface are supplied with Spring. In stand-\n            alone applications, it is common to create an instance of ClassPathXmlApplicationContext or\n            FileSystemXmlApplicationContext.           While     XML     has   been     the   traditional    format     for   defining\n            configuration metadata, you can instruct the container to use Java annotations or code as the\n            metadata    format   by  providing    a small   amount    of XML    configuration    to  declaratively   enable    support\n            for these  additional    metadata    formats.\n\n\n            In most application scenarios, explicit user code is not required to instantiate one or more\n            instances   of a  Spring   IoC  container.    For  example,    in a  web   application    scenario,   a simple   eight   (or\n            so) lines  of boilerplate    web   descriptor    XML    in the  web.xml    file of the  application    typically   suffices\n            (see Convenient     ApplicationContext       Instantiation    for Web    Applications).    If you  use  the  Spring   Tools\n            for Eclipse   (an  Eclipse-powered       development      environment),      you   can  easily  create   this  boilerplate\n            configuration    with   a few  mouse    clicks  or keystrokes.\n\n\n            The  following    diagram    shows    a high-level    view   of how   Spring    works.   Your   application    classes  are\n            combined with configuration metadata so that, after the ApplicationContext is created and\n            initialized,  you  have   a fully configured    and   executable    system   or  application.\n\n            Figure  1.  The  Spring IoC container\n\n\n            Configuration      Metadata\n\n            As the preceding diagram shows, the Spring IoC container consumes a form of configuration\n            metadata. This configuration metadata represents how you, as an application developer, tell the\n            Spring  container    to instantiate,   configure,   and   assemble    the  objects  in your   application.\n\n\n            Configuration metadata is traditionally supplied in a simple and intuitive XML format, which is\n            what   most  of  this chapter   uses  to convey    key  concepts    and  features   of the  Spring   IoC container.\n\n\n                              XML-based     metadata     is not  the  only  allowed    form   of configuration     metadata.     The\n                              Spring IoC container itself is totally decoupled from the format in which this\n                             configuration metadata is actually written. These days, many developers choose\n                              Java-based    configuration    for  their  Spring  applications.\n\n\n            For information     about   using   other  forms   of metadata     with  the  Spring   container,   see:\n\n\n              • Annotation-based         configuration:       Spring     2.5   introduced      support      for   annotation-based\n                configuration     metadata.\n\n              • Java-based configuration: Starting with Spring 3.0, many features provided by the Spring\n                JavaConfig project became part of the core Spring Framework. Thus, you can define beans\n                external to your application classes by using Java rather than XML files. To use these new\n                features,   see the  @Configuration,     @Bean,  @Import,  and   @DependsOn   annotations.\n\n            Spring   configuration     consists  of  at least  one   and  typically   more    than  one   bean   definition   that  the\n            container must manage. XML-based configuration metadata configures these beans as <bean/>\n            elements inside a top-level <beans/> element. Java configuration typically uses @Bean-annotated\n            methods    within   a @Configuration     class.\n\n            These   bean   definitions    correspond     to the  actual   objects   that  make   up   your   application.   Typically,\n            you define service layer objects, data access objects (DAOs), presentation objects such as Struts\n            Action instances, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so\n            forth. Typically,   one   does  not  configure    fine-grained     domain    objects   in the  container,    because    it  is\n\n            usually   the responsibility    of  DAOs   and   business    logic  to create  and   load  domain     objects.  However,\n            you  can   use  Spring’s   integration    with  AspectJ    to configure    objects   that  have   been   created   outside\n            the control   of an  IoC  container.   See  Using   AspectJ   to dependency-inject      domain     objects  with  Spring.\n\n\n            The  following   example     shows   the  basic  structure   of XML-based      configuration     metadata:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"...\"    class=\"...\">      ①   ②\n                         <!--   collaborators      and   configuration      for   this   bean  go   here  -->\n                    </bean>\n\n\n                    <bean   id=\"...\"    class=\"...\">\n                         <!--   collaborators      and   configuration      for   this   bean  go   here  -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      go  here   -->\n\n\n              </beans>\n\n\n            ① The    id attribute   is a string  that identifies   the individual    bean   definition.\n\n            ② The    class  attribute   defines   the type  of the  bean   and  uses   the fully  qualified   classname.\n\n            The  value   of the  id attribute   refers   to collaborating    objects.  The   XML    for referring   to  collaborating\n            objects  is not shown    in  this example.    See  Dependencies      for more    information.\n\n\n            Instantiating    a  Container\n\n            The  location   path   or paths   supplied    to an  ApplicationContext       constructor    are  resource    strings  that\n            let  the  container  load  configuration     metadata    from   a variety   of external   resources,    such  as  the local\n            file  system, the  Java  CLASSPATH,   and   so on.\n\n\n            Java\n\n\n              ApplicationContext        context    =  new   ClassPathXmlApplicationContext(\"services.xml\",\n              \"daos.xml\");\n\n\n\n            Kotlin\n\n\n              val   context    =  ClassPathXmlApplicationContext(\"services.xml\",                  \"daos.xml\")\n\n                              After  you  learn   about   Spring’s   IoC  container,    you   may   want   to  know   more    about\n                              Spring’s   Resource     abstraction     (as  described     in  Resources),     which     provides     a\n                             convenient mechanism for reading an InputStream from locations defined in a\n                              URI syntax. In particular, Resource paths are used to construct applications\n                              contexts,  as  described    in Application    Contexts   and   Resource    Paths.\n\n\n            The  following   example     shows   the  service   layer  objects  (services.xml)     configuration     file:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <!--   services    -->\n\n\n                    <bean   id=\"petStore\"\n              class=\"org.springframework.samples.jpetstore.services.PetStoreServiceImpl\">\n                         <property     name=\"accountDao\"        ref=\"accountDao\"/>\n                         <property     name=\"itemDao\"       ref=\"itemDao\"/>\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      for  services     go  here   -->\n\n\n              </beans>\n\n\n\n            The  following   example     shows   the  data  access   objects  daos.xml   file:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"accountDao\"\n                         class=\"org.springframework.samples.jpetstore.dao.jpa.JpaAccountDao\">\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <bean   id=\"itemDao\"\n              class=\"org.springframework.samples.jpetstore.dao.jpa.JpaItemDao\">\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      for  data   access    objects    go  here   -->\n\n\n              </beans>\n\n            In the  preceding    example,     the  service  layer   consists  of  the  PetStoreServiceImpl       class and   two   data\n            access objects of the types JpaAccountDao and JpaItemDao (based on the JPA Object-Relational\n            Mapping    standard).    The  property    name  element    refers  to the  name   of  the JavaBean     property,   and  the\n            ref element refers to the name of another bean definition. This linkage between id and ref\n            elements expresses the dependency between collaborating objects. For details of configuring an\n            object’s  dependencies,     see  Dependencies.\n\n\n\n            Composing    XML-based    Configuration   Metadata\n\n            It can be useful to have bean definitions span multiple XML files. Often, each individual XML\n            configuration    file represents    a logical  layer  or module     in your  architecture.\n\n\n            You can use the application context constructor to load bean definitions from all these XML\n            fragments.    This  constructor    takes  multiple   Resource   locations,   as was   shown    in the  previous    section.\n            Alternatively,   use  one   or more    occurrences     of the  <import/>    element    to load   bean   definitions   from\n            another   file or files. The  following    example    shows    how   to do  so:\n\n\n\n              <beans>\n                    <import    resource=\"services.xml\"/>\n                    <import    resource=\"resources/messageSource.xml\"/>\n                    <import    resource=\"/resources/themeSource.xml\"/>\n\n\n                    <bean   id=\"bean1\"     class=\"...\"/>\n                    <bean   id=\"bean2\"     class=\"...\"/>\n              </beans>\n\n\n\n            In the preceding example, external bean definitions are loaded from three files: services.xml,\n            messageSource.xml,      and  themeSource.xml.      All location   paths   are   relative  to  the  definition   file doing\n            the importing,    so  services.xml    must    be in  the same    directory   or  classpath   location   as  the file doing\n            the importing,     while  messageSource.xml       and  themeSource.xml      must   be  in  a resources    location   below\n            the  location   of the  importing     file.  As  you can  see,  a leading    slash  is ignored.   However,     given   that\n            these  paths   are  relative,  it is better  form   not  to  use  the  slash  at all. The  contents    of the  files being\n            imported,    including   the  top  level  <beans/>   element,    must   be  valid  XML    bean   definitions,   according\n            to the Spring   Schema.\n\n                              It  is  possible,  but  not  recommended,     to reference    files in parent   directories   using   a\n                              relative \"../\" path. Doing so creates a dependency on a file that is outside the\n                              current    application.     In   particular,    this   reference     is  not   recommended          for\n                              classpath: URLs (for example, classpath:../services.xml), where the runtime\n                              resolution process chooses the “nearest” classpath root and then looks into its\n                              parent directory. Classpath configuration changes may lead to the choice of a\n                              different,  incorrect   directory.\n                \n                              You  can  always    use  fully qualified    resource   locations   instead   of  relative  paths:   for\n                              example,        file:C:/config/services.xml             or     classpath:/config/services.xml.\n                              However, be aware that you are coupling your application’s configuration to\n                              specific  absolute   locations.   It  is  generally  preferable  to keep   an indirection    for such\n                              absolute locations — for example, through \"${…}\" placeholders that are resolved\n                              against  JVM   system   properties    at runtime.\n\n\n            The  namespace      itself provides    the  import   directive   feature.  Further    configuration     features   beyond\n            plain bean definitions are available in a selection of XML namespaces provided by Spring — for\n            example,    the context   and   util  namespaces.\n\n\n\n            The Groovy   Bean   Definition  DSL\n\n            As a further example for externalized configuration metadata, bean definitions can also be\n            expressed    in Spring’s   Groovy    Bean   Definition    DSL,  as known     from   the  Grails  framework.     Typically,\n            such  configuration     live in a \".groovy\"    file  with the structure   shown    in  the following    example:\n\n\n\n              beans    {\n                    dataSource(BasicDataSource)           {\n                         driverClassName       =  \"org.hsqldb.jdbcDriver\"\n                         url   =  \"jdbc:hsqldb:mem:grailsDB\"\n                         username     = \"sa\"\n                         password     = \"\"\n                         settings     = [mynew:\"setting\"]\n                    }\n                    sessionFactory(SessionFactory)            {\n                         dataSource     =  dataSource\n                    }\n                    myService(MyService)         {\n                         nestedBean     =  {  AnotherBean     bean   ->\n                               dataSource     =  dataSource\n                         }\n                    }\n              }\n\n\n\n            This  configuration     style  is largely  equivalent     to XML    bean   definitions    and  even   supports    Spring’s\n            XML   configuration     namespaces.      It also  allows   for importing     XML    bean   definition   files through    an\n            importBeans    directive.\n\n            Using   the  Container\n\n            The  ApplicationContext      is the  interface   for an  advanced     factory  capable    of maintaining     a registry   of\n            different beans and their dependencies. By using the method T getBean(String name, Class<T>\n            requiredType),    you  can  retrieve   instances   of  your  beans.\n\n            The  ApplicationContext       lets you   read   bean   definitions   and   access   them,   as  the  following    example\n            shows:\n\n\n            Java\n\n\n              //  create    and   configure    beans\n              ApplicationContext        context    =  new   ClassPathXmlApplicationContext(\"services.xml\",\n              \"daos.xml\");\n\n\n              //  retrieve     configured     instance\n              PetStoreService       service    =  context.getBean(\"petStore\",            PetStoreService.class);\n\n\n              //  use   configured     instance\n              List<String>      userList     = service.getUsernameList();\n\n\n\n            Kotlin\n\n\n              import    org.springframework.beans.factory.getBean\n\n\n              //  create    and   configure    beans\n              val   context    =  ClassPathXmlApplicationContext(\"services.xml\",                  \"daos.xml\")\n\n\n              //  retrieve     configured     instance\n              val   service    =  context.getBean<PetStoreService>(\"petStore\")\n\n\n              //  use   configured     instance\n              var   userList    =  service.getUsernameList()\n\n\n\n            With    Groovy     configuration,      bootstrapping       looks    very    similar.   It  has    a   different    context\n            implementation class which is Groovy-aware (but also understands XML bean definitions). The\n            following   example    shows    Groovy    configuration:\n\n\n            Java\n\n\n              ApplicationContext        context    =  new   GenericGroovyApplicationContext(\"services.groovy\",\n              \"daos.groovy\");\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericGroovyApplicationContext(\"services.groovy\",                    \"daos.groovy\")\n\n\n\n            The  most   flexible  variant   is GenericApplicationContext         in  combination     with   reader   delegates — for\n            example,    with  XmlBeanDefinitionReader        for XML    files,  as  the  following example    shows:\n\n            Java\n\n\n              GenericApplicationContext           context    =  new  GenericApplicationContext();\n              new   XmlBeanDefinitionReader(context).loadBeanDefinitions(\"services.xml\",                           \"daos.xml\");\n              context.refresh();\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericApplicationContext()\n              XmlBeanDefinitionReader(context).loadBeanDefinitions(\"services.xml\",                           \"daos.xml\")\n              context.refresh()\n\n\n\n            You  can  also  use  the GroovyBeanDefinitionReader         for Groovy    files, as the  following   example     shows:\n\n\n            Java\n\n\n              GenericApplicationContext           context    =  new  GenericApplicationContext();\n              new   GroovyBeanDefinitionReader(context).loadBeanDefinitions(\"services.groovy\",\n              \"daos.groovy\");\n              context.refresh();\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericApplicationContext()\n              GroovyBeanDefinitionReader(context).loadBeanDefinitions(\"services.groovy\",\n              \"daos.groovy\")\n              context.refresh()\n\n\n\n            You can mix and match such reader delegates on the same ApplicationContext, reading bean\n            definitions   from   diverse  configuration     sources.\n\n\n            You  can  then  use  getBean   to retrieve   instances    of your  beans.   The  ApplicationContext       interface   has  a\n            few  other   methods    for  retrieving   beans,   but,  ideally, your   application    code   should   never   use  them.\n            Indeed,   your  application    code   should   have   no  calls to  the getBean()    method    at  all  and thus  have   no\n            dependency      on Spring   APIs   at all.  For  example,  Spring’s   integration    with  web   frameworks      provides\n            dependency     injection   for  various   web   framework     components      such   as controllers    and  JSF-managed\n            beans, letting you declare a dependency on a specific bean through metadata (such as an\n            autowiring    annotation).\n\n\n            2.1.3.   Bean     Overview\n\n            A Spring   IoC  container    manages    one   or more    beans.  These   beans   are  created   with   the configuration\n            metadata    that  you  supply   to the  container    (for example,    in the  form   of XML   <bean/>   definitions).\n\n\n            Within   the  container    itself,  these bean   definitions   are  represented     as BeanDefinition     objects,   which\n            contain   (among    other  information)     the  following   metadata:\n\n              • A package-qualified class name: typically, the actual implementation class of the bean being\n\n                defined.\n\n              • Bean behavioral configuration elements, which state how the bean should behave in the\n                container    (scope,  lifecycle  callbacks,   and  so  forth).\n\n              • References     to other  beans   that  are  needed    for the  bean   to do  its work.  These   references    are  also\n                called  collaborators    or  dependencies.\n\n              • Other   configuration     settings   to set  in the  newly    created   object — for    example,    the  size  limit  of\n                the  pool  or the  number     of connections     to use  in a bean   that  manages    a  connection    pool.\n\n\n            This metadata translates to a set of properties that make up each bean definition. The following\n            table describes    these  properties:\n\n\n            Table 1. The  bean  definition\n\n            Property                                                       Explained     in…\n\n            Class                                                          Instantiating   Beans\n\n            Name                                                           Naming    Beans\n\n            Scope                                                          Bean   Scopes\n\n            Constructor     arguments                                      Dependency      Injection\n\n            Properties                                                     Dependency      Injection\n\n            Autowiring     mode                                            Autowiring     Collaborators\n\n            Lazy   initialization   mode                                   Lazy-initialized    Beans\n\n            Initialization   method                                        Initialization   Callbacks\n\n            Destruction     method                                         Destruction    Callbacks\n\n\n            In addition to bean definitions that contain information on how to create a specific bean, the\n            ApplicationContext      implementations       also  permit   the  registration   of existing   objects  that  are  created\n            outside the container (by users). This is done by accessing the ApplicationContext’s BeanFactory\n            through      the     getBeanFactory()        method,       which      returns      the    DefaultListableBeanFactory\n            implementation.          DefaultListableBeanFactory            supports       this     registration       through       the\n            registerSingleton(..)        and    registerBeanDefinition(..)          methods.     However,      typical   applications\n            work   solely  with  beans   defined   through    regular   bean   definition   metadata.\n\n\n                              Bean   metadata    and   manually    supplied    singleton   instances   need   to be  registered    as\n                              early  as possible,   in order   for  the container    to properly    reason    about   them   during\n                              autowiring    and   other  introspection     steps.  While   overriding    existing   metadata    and\n                             existing  singleton    instances    is supported    to  some    degree,   the  registration   of  new\n                              beans at runtime (concurrently with live access to the factory) is not officially\n                              supported    and   may   lead  to  concurrent    access   exceptions,    inconsistent    state  in the\n                              bean  container,    or both.\n\n\n\n            Naming     Beans\n\n            Every   bean   has  one  or  more   identifiers.  These   identifiers   must   be  unique    within   the container    that\n            hosts  the  bean.   A bean   usually   has   only  one   identifier.  However,     if it  requires  more   than   one,  the\n\n            extra  ones  can  be  considered     aliases.\n\n\n            In XML-based      configuration    metadata,    you   use  the  id attribute,  the  name  attribute,  or  both  to specify\n            the  bean   identifiers.  The   id  attribute   lets you   specify  exactly   one   id. Conventionally,     these   names\n            are  alphanumeric      ('myBean',    'someService',    etc.), but  they  can  contain    special  characters    as  well. If\n            you  want    to introduce    other   aliases  for  the  bean,   you  can   also  specify  them    in the  name   attribute,\n            separated    by  a comma     (,), semicolon     (;), or white   space.   As  a historical   note,  in  versions   prior   to\n            Spring   3.1,  the  id  attribute  was defined   as  an xsd:ID   type,  which   constrained     possible   characters.   As\n            of 3.1, it is defined as an xsd:string type. Note that bean id uniqueness is still enforced by the\n            container,   though   no  longer   by  XML   parsers.\n\n\n            You  are  not  required   to supply    a name  or an  id for  a bean.   If  you do not  supply   a  name  or id explicitly,\n            the container    generates    a unique    name    for that  bean.  However,     if you  want   to refer  to  that bean   by\n            name, through the use of the ref element or a Service Locator style lookup, you must provide a\n            name. Motivations for not supplying a name are related to using inner beans and autowiring\n            collaborators.\n\n\n                                                    Bean     Naming        Conventions\n\n               The   convention     is  to  use  the  standard Java  convention     for  instance   field names    when    naming\n               beans. That is, bean names start with a lowercase letter and are camel-cased from there.\n               Examples     of such   names    include   accountManager,    accountService,     userDao,   loginController,     and\n               so  forth.\n\n\n               Naming     beans   consistently    makes    your   configuration     easier  to read   and   understand.     Also,  if\n               you   use  Spring  AOP,   it  helps a lot when   applying    advice   to a set of beans    related  by  name.\n\n\n\n\n                              With component scanning in the classpath, Spring generates bean names for\n                              unnamed     components,      following    the rules  described    earlier:  essentially,   taking  the\n                              simple   class  name    and  turning    its  initial  character  to lower-case.    However,     in the\n                             (unusual)    special  case   when    there  is more    than   one   character    and  both   the  first\n                              and  second   characters    are  upper   case,  the  original  casing   gets preserved.    These   are\n                              the same    rules  as  defined   by  java.beans.Introspector.decapitalize            (which    Spring\n                              uses  here).\n\n\n\n            Aliasing a Bean   outside  the Bean  Definition\n\n            In a bean definition itself, you can supply more than one name for the bean, by using a\n            combination     of up  to  one  name    specified   by  the id  attribute  and   any  number     of other   names    in the\n            name attribute. These names can be equivalent aliases to the same bean and are useful for some\n            situations, such as letting each component in an application refer to a common dependency by\n            using  a bean   name    that is specific  to that  component      itself.\n\n            Specifying all aliases where the bean is actually defined is not always adequate, however. It is\n            sometimes     desirable   to  introduce    an  alias  for a  bean   that  is defined   elsewhere.     This  is commonly\n            the case in large systems where configuration is split amongst each subsystem, with each\n            subsystem     having   its own   set  of object   definitions.   In XML-based      configuration     metadata,    you   can\n            use the  <alias/>   element    to accomplish     this. The  following    example    shows    how   to do  so:\n\n              <alias    name=\"fromName\"       alias=\"toName\"/>\n\n\n\n            In this case, a bean (in the same container) named fromName may also, after the use of this alias\n            definition,  be  referred   to as  toName.\n\n\n            For example,     the configuration     metadata    for  subsystem     A may   refer  to a  DataSource     by the  name    of\n            subsystemA-dataSource.       The  configuration     metadata     for  subsystem     B  may   refer  to a  DataSource     by\n            the name of subsystemB-dataSource. When composing the main application that uses both these\n            subsystems,    the  main   application    refers  to the  DataSource     by  the name    of myApp-dataSource.     To  have\n            all three names refer to the same object, you can add the following alias definitions to the\n            configuration    metadata:\n\n\n\n              <alias    name=\"myApp-dataSource\"          alias=\"subsystemA-dataSource\"/>\n              <alias    name=\"myApp-dataSource\"          alias=\"subsystemB-dataSource\"/>\n\n\n\n            Now   each   component      and  the  main   application    can   refer  to the  dataSource    through    a  name   that  is\n            unique   and   guaranteed      not  to clash   with  any   other   definition   (effectively   creating   a  namespace),\n            yet they  refer  to the  same   bean.\n\n\n                                                           Java-configuration\n\n               If you   use  Javaconfiguration,      the  @Bean  annotation     can   be used   to  provide   aliases.  See   Using\n               the  @Bean  Annotation     for details.\n\n\n\n\n            Instantiating    Beans\n\n            A bean   definition   is essentially   a recipe   for creating   one   or more   objects.   The  container    looks  at the\n            recipe for a named bean when asked and uses the configuration metadata encapsulated by that\n            bean  definition   to  create  (or acquire)   an  actual   object.\n\n\n            If  you use  XML-based      configuration     metadata,    you  specify   the  type  (or  class) of  object  that  is to be\n            instantiated   in  the class  attribute   of the  <bean/>   element.    This  class  attribute   (which,   internally,  is a\n            Class   property      on   a   BeanDefinition      instance)     is  usually    mandatory.       (For   exceptions,     see\n            Instantiation    by  Using   an  Instance   Factory    Method    and   Bean   Definition    Inheritance.)    You   can  use\n            the Class  property    in one   of two  ways:\n\n\n              • Typically, to specify the bean class to be constructed in the case where the container itself\n                directly creates the bean by calling its constructor reflectively, somewhat equivalent to Java\n                code   with  the  new operator.\n\n              • To specify the actual class containing the static factory method that is invoked to create the\n                object,  in the  less common      case  where    the  container    invokes   a static   factory   method    on  a class\n                to create   the  bean.   The  object   type  returned    from    the invocation     of the  static   factory   method\n                may   be  the same    class or  another   class  entirely.\n\n                                                          Nested      class    names\n\n               If you   want   to configure    a  bean   definition   for  a nested   class,  you  may    use  either  the  binary\n               name    or the  source   name    of the  nested   class.\n\n\n               For example, if you have a class called SomeThing in the com.example package, and this\n               SomeThing    class  has  a static   nested   class  called  OtherThing,    they  can   be  separated    by  a dollar\n               sign ($) or a dot (.). So the value of the class attribute in a bean definition would be\n               com.example.SomeThing$OtherThing           or com.example.SomeThing.OtherThing.\n\n\n\n\n\n            Instantiation  with  a Constructor\n\n            When you create a bean by the constructor approach, all normal classes are usable by and\n            compatible    with   Spring.  That   is,  the  class  being developed    does   not  need   to implement     any   specific\n            interfaces or to be coded in a specific fashion. Simply specifying the bean class should suffice.\n            However,     depending     on  what    type  of  IoC  you  use   for that  specific   bean,   you  may    need   a default\n            (empty)   constructor.\n\n\n            The  Spring   IoC  container    can  manage     virtually   any  class  you  want   it to manage.     It  is  not  limited  to\n            managing true JavaBeans. Most Spring users prefer actual JavaBeans with only a default (no-\n            argument) constructor and appropriate setters and getters modeled after the properties in the\n            container.   You   can  also  have   more   exotic  non-bean-style      classes  in  your  container.    If,  for  example,\n            you need to use a legacy connection pool that absolutely does not adhere to the JavaBean\n            specification,   Spring   can  manage    it as well.\n\n\n            With  XML-based      configuration     metadata    you  can   specify  your   bean   class as follows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\"/>\n\n\n              <bean    name=\"anotherExample\"         class=\"examples.ExampleBeanTwo\"/>\n\n\n\n            For details about the mechanism for supplying arguments to the constructor (if required) and\n            setting  object  instance   properties    after the  object  is constructed,    see  Injecting  Dependencies.\n\n\n\n            Instantiation  with  a Static Factory  Method\n\n            When    defining   a bean   that  you  create  with   a static factory   method,    use  the class   attribute  to specify\n            the class  that  contains   the  static   factory   method    and   an  attribute   named    factory-method     to specify\n            the name of the factory method itself. You should be able to call this method (with optional\n            arguments,     as described    later)  and   return   a live  object,  which    subsequently     is treated   as  if it had\n            been  created    through    a constructor.    One   use  for such   a bean   definition   is to call static   factories   in\n            legacy  code.\n\n\n            The  following    bean   definition   specifies   that  the  bean   will  be  created   by  calling   a factory   method.\n            The definition does not specify the type (class) of the returned object, but rather the class\n            containing the factory method. In this example, the createInstance() method must be a static\n            method.   The   following   example     shows   how   to specify   a factory   method:\n\n              <bean    id=\"clientService\"\n                    class=\"examples.ClientService\"\n                    factory-method=\"createInstance\"/>\n\n\n\n            The  following   example     shows   a class  that  would   work    with  the  preceding    bean   definition:\n\n\n            Java\n\n\n              public    class   ClientService      {\n                    private    static   ClientService       clientService      =  new  ClientService();\n                    private    ClientService()       {}\n\n\n                    public   static    ClientService      createInstance()        {\n                         return    clientService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ClientService      private    constructor()      {\n                    companion     object   {\n                         private    val   clientService      =  ClientService()\n                         @JvmStatic\n                         fun   createInstance()       =  clientService\n                    }\n              }\n\n\n\n            For details about the mechanism for supplying (optional) arguments to the factory method and\n            setting  object   instance   properties    after  the  object   is returned    from   the  factory,   see  Dependencies\n            and  Configuration     in Detail.\n\n\n\n            Instantiation  by Using  an  Instance  Factory  Method\n\n            Similar to instantiation through a static factory method, instantiation with an instance factory\n            method    invokes    a non-static   method     of an  existing   bean   from   the  container    to create   a new   bean.\n            To  use  this mechanism,      leave   the  class   attribute  empty    and,   in the  factory-bean     attribute,  specify\n            the name of a bean in the current (or parent or ancestor) container that contains the instance\n            method    that  is  to  be  invoked to  create  the  object.  Set the  name    of the  factory   method    itself with  the\n            factory-method     attribute.  The  following    example    shows    how   to configure    such  a bean:\n\n              <!--   the   factory    bean,   which   contains     a method    called    createInstance()       -->\n              <bean    id=\"serviceLocator\"        class=\"examples.DefaultServiceLocator\">\n                    <!--   inject   any   dependencies      required    by  this   locator    bean   -->\n              </bean>\n\n\n              <!--   the   bean   to  be  created    via  the   factory    bean   -->\n              <bean    id=\"clientService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createClientServiceInstance\"/>\n\n\n\n            The  following   example     shows   the  corresponding      class:\n\n\n            Java\n\n\n              public    class   DefaultServiceLocator         {\n\n\n                    private    static   ClientService       clientService      =  new  ClientServiceImpl();\n\n\n                    public   ClientService       createClientServiceInstance()            {\n                         return    clientService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    DefaultServiceLocator         {\n                    companion     object   {\n                         private    val   clientService      =  ClientServiceImpl()\n                    }\n                    fun  createClientServiceInstance():             ClientService      {\n                         return    clientService\n                    }\n              }\n\n\n\n            One  factory   class can   also hold   more   than  one   factory  method,    as the  following    example    shows:\n\n\n\n              <bean    id=\"serviceLocator\"        class=\"examples.DefaultServiceLocator\">\n                    <!--   inject   any   dependencies      required    by  this   locator    bean   -->\n              </bean>\n\n\n              <bean    id=\"clientService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createClientServiceInstance\"/>\n\n\n              <bean    id=\"accountService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createAccountServiceInstance\"/>\n\n            The  following   example     shows   the  corresponding      class:\n\n\n            Java\n\n\n              public    class   DefaultServiceLocator         {\n\n\n                    private    static   ClientService       clientService      =  new  ClientServiceImpl();\n\n\n                    private    static   AccountService       accountService       = new   AccountServiceImpl();\n\n\n                    public   ClientService       createClientServiceInstance()            {\n                         return    clientService;\n                    }\n\n\n                    public   AccountService       createAccountServiceInstance()             {\n                         return    accountService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    DefaultServiceLocator         {\n                    companion     object   {\n                         private    val   clientService      =  ClientServiceImpl()\n                         private    val   accountService      =  AccountServiceImpl()\n                    }\n\n\n                    fun  createClientServiceInstance():             ClientService      {\n                         return    clientService\n                    }\n\n\n                    fun  createAccountServiceInstance():             AccountService       {\n                         return    accountService\n                    }\n              }\n\n\n\n            This approach shows that the factory bean itself can be managed and configured through\n            dependency     injection   (DI). See  Dependencies      and   Configuration     in Detail.\n\n\n                              In Spring   documentation,       \"factory   bean\"   refers  to a  bean   that is configured     in the\n                              Spring container and that creates objects through an instance or static factory\n                             method. By contrast, FactoryBean (notice the capitalization) refers to a Spring-\n                              specific  FactoryBean    implementation       class.\n\n\n\n            Determining    a Bean’s Runtime    Type\n\n            The runtime type of a specific bean is non-trivial to determine. A specified class in the bean\n            metadata    definition   is just  an  initial class  reference,    potentially   combined      with  a  declared   factory\n            method    or being   a  FactoryBean    class which    may   lead  to  a different   runtime    type  of the  bean,   or not\n\n            being set at all in case of an instance-level factory method (which is resolved via the specified\n            factory-bean name instead). Additionally, AOP proxying may wrap a bean instance with an\n            interface-based     proxy   with   limited  exposure     of the  target   bean’s  actual   type  (just  its implemented\n            interfaces).\n\n            The recommended way to find out about the actual runtime type of a particular bean is a\n            BeanFactory.getType      call  for the  specified   bean   name.   This   takes  all of the  above   cases   into account\n            and  returns   the  type   of object   that a  BeanFactory.getBean       call is going   to return   for  the  same   bean\n            name.\n\n            2.1.4.   Dependencies\n\n            A typical  enterprise    application    does   not  consist  of a  single  object  (or  bean   in the  Spring   parlance).\n            Even   the  simplest   application    has   a few   objects   that  work   together    to present    what   the  end-user\n            sees  as a  coherent    application.    This  next  section   explains    how   you   go  from   defining   a  number     of\n            bean  definitions    that stand   alone  to  a fully realized   application    where   objects   collaborate    to achieve\n            a goal.\n\n\n            Dependency       Injection\n\n            Dependency      injection   (DI) is a process   whereby     objects  define   their  dependencies      (that is, the  other\n            objects  with  which    they  work)   only  through    constructor    arguments,     arguments     to a factory   method,\n            or properties    that  are  set  on  the  object  instance    after  it  is  constructed  or  returned    from   a factory\n            method. The container then injects those dependencies when it creates the bean. This process is\n            fundamentally      the  inverse   (hence   the  name,   Inversion    of  Control)   of the  bean   itself controlling   the\n            instantiation   or  location  of  its  dependencies    on  its own   by  using  direct  construction    of  classes  or the\n            Service  Locator    pattern.\n\n\n            Code   is cleaner   with  the  DI  principle,   and   decoupling    is more    effective  when    objects   are  provided\n            with their dependencies. The object does not look up its dependencies and does not know the\n            location   or class  of  the  dependencies.      As  a result,  your   classes   become    easier   to test, particularly\n            when the dependencies are on interfaces or abstract base classes, which allow for stub or mock\n            implementations       to be used   in unit  tests.\n\n\n            DI  exists   in   two    major    variants:    Constructor-based        dependency       injection    and    Setter-based\n            dependency     injection.\n\n\n\n            Constructor-based    Dependency     Injection\n\n            Constructor-based DI is accomplished by the container invoking a constructor with a number of\n            arguments,      each   representing      a  dependency.       Calling   a   static   factory    method     with    specific\n            arguments to construct the bean is nearly equivalent, and this discussion treats arguments to a\n            constructor    and  to  a static   factory  method     similarly.  The  following    example    shows    a class  that  can\n            only  be dependency-injected        with  constructor     injection:\n\n            Java\n\n\n              public    class   SimpleMovieLister        {\n\n\n                    //  the  SimpleMovieLister        has   a dependency      on  a MovieFinder\n                    private    final   MovieFinder      movieFinder;\n\n\n                    //  a  constructor     so  that   the   Spring   container     can   inject   a  MovieFinder\n                    public   SimpleMovieLister(MovieFinder             movieFinder)      {\n                         this.movieFinder        = movieFinder;\n                    }\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Kotlin\n\n\n              //  a  constructor      so  that   the  Spring    container     can  inject    a MovieFinder\n              class    SimpleMovieLister(private          val   movieFinder:      MovieFinder)      {\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Notice that there is nothing special about this class. It is a POJO that has no dependencies on\n            container   specific  interfaces,   base   classes, or  annotations.\n\n\n            Constructor     Argument      Resolution\n\n            Constructor argument resolution matching occurs by using the argument’s type. If no potential\n            ambiguity exists in the constructor arguments of a bean definition, the order in which the\n            constructor    arguments     are  defined    in a bean   definition    is the order   in  which   those   arguments     are\n            supplied   to the  appropriate     constructor    when   the  bean   is being   instantiated.   Consider    the following\n            class:\n\n\n            Java\n\n\n              package    x.y;\n\n\n              public    class   ThingOne     {\n\n\n                    public   ThingOne(ThingTwo        thingTwo,     ThingThree     thingThree)      {\n                         //  ...\n                    }\n              }\n\n            Kotlin\n\n\n              package    x.y\n\n\n              class    ThingOne(thingTwo:        ThingTwo,    thingThree:      ThingThree)\n\n\n\n            Assuming that the ThingTwo and ThingThree classes are not related by inheritance, no potential\n            ambiguity    exists.  Thus,  the  following    configuration     works    fine, and   you  do  not  need   to  specify  the\n            constructor    argument     indexes   or types   explicitly  in the  <constructor-arg/>      element.\n\n\n\n              <beans>\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\">\n                         <constructor-arg        ref=\"beanTwo\"/>\n                         <constructor-arg        ref=\"beanThree\"/>\n                    </bean>\n\n\n                    <bean   id=\"beanTwo\"      class=\"x.y.ThingTwo\"/>\n\n\n                    <bean   id=\"beanThree\"       class=\"x.y.ThingThree\"/>\n              </beans>\n\n\n\n            When    another   bean   is referenced,    the  type  is known,    and  matching     can  occur   (as was   the case   with\n            the preceding example). When a simple type is used, such as <value>true</value>, Spring cannot\n            determine    the  type  of  the  value,  and  so  cannot   match    by  type  without    help.  Consider    the following\n            class:\n\n\n            Java\n\n\n              package    examples;\n\n\n              public    class   ExampleBean      {\n\n\n                    //  Number    of  years   to  calculate     the  Ultimate     Answer\n                    private    final   int   years;\n\n\n                    //  The  Answer    to  Life,   the   Universe,     and  Everything\n                    private    final   String    ultimateAnswer;\n\n\n                    public   ExampleBean(int       years,    String    ultimateAnswer)       {\n                         this.years     =  years;\n                         this.ultimateAnswer         =  ultimateAnswer;\n                    }\n              }\n\n            Kotlin\n\n\n              package    examples\n\n\n              class    ExampleBean(\n                    private    val  years:    Int,   //  Number    of  years   to  calculate     the  Ultimate     Answer\n                    private    val  ultimateAnswer:       String    //  The   Answer   to  Life,    the  Universe,     and\n              Everything\n              )\n\n\n\n            Constructor   argument    type  matching\n            In the  preceding    scenario,    the  container    can  use  type  matching     with   simple   types  if you   explicitly\n            specify  the  type  of  the  constructor    argument     by  using   the  type  attribute,  as  the  following    example\n            shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       type=\"int\"     value=\"7500000\"/>\n                    <constructor-arg       type=\"java.lang.String\"          value=\"42\"/>\n              </bean>\n\n\n\n            Constructor   argument    index\n            You can use the index attribute to specify explicitly the index of constructor arguments, as the\n            following   example    shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       index=\"0\"     value=\"7500000\"/>\n                    <constructor-arg       index=\"1\"     value=\"42\"/>\n              </bean>\n\n\n\n            In addition to resolving the ambiguity of multiple simple values, specifying an index resolves\n            ambiguity    where    a constructor    has  two  arguments     of  the same    type.\n\n                             The  index   is  0-based.\n\n\n            Constructor   argument    name\n            You can also use the constructor parameter name for value disambiguation, as the following\n            example    shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       name=\"years\"      value=\"7500000\"/>\n                    <constructor-arg       name=\"ultimateAnswer\"         value=\"42\"/>\n              </bean>\n\n\n\n            Keep   in mind    that, to  make   this  work   out  of  the  box,  your   code  must    be  compiled    with   the  debug\n            flag enabled    so that  Spring   can  look   up  the parameter     name    from   the  constructor.    If you  cannot    or\n\n            do not  want   to  compile   your   code   with  the  debug   flag, you   can  use  the  @ConstructorProperties         JDK\n            annotation to explicitly name your constructor arguments. The sample class would then have to\n            look  as follows:\n\n\n            Java\n\n\n              package    examples;\n\n\n              public    class   ExampleBean      {\n\n\n                    //  Fields    omitted\n\n\n                    @ConstructorProperties({\"years\",             \"ultimateAnswer\"})\n                    public   ExampleBean(int       years,    String    ultimateAnswer)       {\n                         this.years     =  years;\n                         this.ultimateAnswer         =  ultimateAnswer;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              package    examples\n\n\n              class    ExampleBean\n              @ConstructorProperties(\"years\",             \"ultimateAnswer\")\n              constructor(val       years:    Int,   val  ultimateAnswer:       String)\n\n\n\n\n            Setter-based  Dependency     Injection\n\n            Setter-based DI is accomplished by the container calling setter methods on your beans after\n            invoking a no-argument constructor or a no-argument static factory method to instantiate your\n            bean.\n\n            The following example shows a class that can only be dependency-injected by using pure setter\n            injection.  This  class  is  conventional   Java.  It is  a  POJO that has  no  dependencies      on  container    specific\n            interfaces,  base   classes,  or annotations.\n\n            Java\n\n\n              public    class   SimpleMovieLister        {\n\n\n                    //  the  SimpleMovieLister        has   a dependency      on  the  MovieFinder\n                    private    MovieFinder     movieFinder;\n\n\n                    //  a  setter   method    so  that   the  Spring    container     can  inject    a  MovieFinder\n                    public   void   setMovieFinder(MovieFinder           movieFinder)      {\n                         this.movieFinder        = movieFinder;\n                    }\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Kotlin\n\n\n              class    SimpleMovieLister       {\n\n\n                    //  a  late-initialized       property    so   that  the   Spring    container    can   inject   a\n              MovieFinder\n                    lateinit    var   movieFinder:      MovieFinder\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            The  ApplicationContext      supports    constructor-based       and  setter-based    DI  for the  beans   it manages.    It\n            also supports setter-based DI after some dependencies have already been injected through the\n            constructor    approach.    You   configure    the  dependencies      in the  form   of  a BeanDefinition,     which    you\n            use  in conjunction     with  PropertyEditor     instances    to convert   properties    from   one  format   to  another.\n            However,    most   Spring   users   do  not  work   with   these  classes  directly   (that is, programmatically)       but\n            rather  with   XML   bean  definitions,   annotated    components      (that  is,  classes annotated    with  @Component,\n            @Controller,   and   so forth),  or @Bean   methods    in  Java-based    @Configuration     classes.  These   sources   are\n            then converted internally into instances of BeanDefinition and used to load an entire Spring IoC\n            container   instance.\n\n                                           Constructor-based              or  setter-based          DI?\n\n               Since   you   can  mix   constructor-based       and  setter-based     DI, it is a  good   rule  of thumb     to use\n               constructors     for  mandatory      dependencies      and  setter   methods    or  configuration     methods     for\n               optional    dependencies.     Note   that  use  of  the  @Autowired      annotation     on  a setter   method    can\n               be  used   to make   the  property    be  a required    dependency;     however,     constructor    injection   with\n               programmatic       validation   of arguments      is  preferable.\n\n               The    Spring    team    generally     advocates     constructor     injection,    as  it  lets  you    implement\n               application components as immutable objects and ensures that required dependencies are\n               not null. Furthermore, constructor-injected components are always returned to the client\n               (calling) code in a fully initialized state. As a side note, a large number of constructor\n               arguments     is a bad   code  smell,  implying    that  the class  likely  has  too many    responsibilities    and\n               should   be  refactored    to better  address    proper   separation    of concerns.\n\n\n               Setter  injection   should   primarily    only  be  used   for optional   dependencies      that  can  be  assigned\n               reasonable default values within the class. Otherwise, not-null checks must be performed\n               everywhere the code uses the dependency. One benefit of setter injection is that setter\n               methods make objects of that class amenable to reconfiguration or re-injection later.\n               Management       through    JMX   MBeans     is  therefore  a compelling    use  case  for  setter  injection.\n\n\n               Use   the  DI  style that  makes     the  most   sense   for a  particular   class.  Sometimes,     when    dealing\n               with   third-party   classes   for which   you   do  not  have  the  source,   the  choice  is made    for you.  For\n               example,    if a third-party    class  does  not  expose   any   setter  methods,    then  constructor     injection\n               may   be  the  only  available   form   of DI.\n\n\n\n\n\n            Dependency    Resolution   Process\n\n            The  container    performs    bean   dependency      resolution   as  follows:\n\n\n              • The   ApplicationContext      is created   and   initialized  with  configuration     metadata     that  describes   all\n                the  beans.  Configuration     metadata     can  be  specified   by XML,   Java   code,  or annotations.\n\n              • For  each  bean,   its dependencies      are expressed     in the  form  of  properties,   constructor    arguments,\n                or arguments to the static-factory method (if you use that instead of a normal constructor).\n                These   dependencies      are  provided    to the bean,   when    the bean   is actually   created.\n\n              • Each   property    or constructor    argument     is an  actual   definition   of the  value  to  set,  or  a reference\n                to another    bean   in the  container.\n\n              • Each   property    or constructor     argument     that  is  a  value  is  converted  from   its  specified format    to\n                the  actual  type  of  that property    or  constructor    argument.     By default,   Spring   can  convert   a value\n                supplied   in  string  format   to all built-in  types,  such  as int,  long, String,   boolean,  and   so forth.\n\n            The  Spring   container    validates   the configuration     of each   bean   as the  container    is  created. However,\n            the bean properties themselves are not set until the bean is actually created. Beans that are\n            singleton-scoped and set to be pre-instantiated (the default) are created when the container is\n            created. Scopes are defined in Bean Scopes. Otherwise, the bean is created only when it is\n            requested. Creation of a bean potentially causes a graph of beans to be created, as the bean’s\n            dependencies      and  its dependencies'      dependencies      (and  so  on)  are  created   and   assigned.    Note  that\n\n            resolution   mismatches      among     those  dependencies      may    show   up  late — that    is,  on  first  creation of\n            the affected   bean.\n\n\n                                                       Circular       dependencies\n\n               If you use predominantly constructor injection, it is possible to create an unresolvable\n               circular   dependency      scenario.\n\n\n               For  example:    Class  A  requires   an  instance   of class  B through    constructor    injection,   and  class  B\n               requires an instance of class A through constructor injection. If you configure beans for\n               classes   A  and  B  to be  injected   into  each   other,  the  Spring   IoC  container    detects   this  circular\n               reference    at runtime,    and  throws    a BeanCurrentlyInCreationException.\n\n\n               One   possible    solution   is to edit  the  source   code   of  some   classes   to be   configured    by  setters\n               rather than constructors. Alternatively, avoid constructor injection and use setter injection\n               only.   In   other    words,    although     it  is  not    recommended,        you    can    configure     circular\n               dependencies      with  setter  injection.\n\n\n               Unlike   the  typical  case  (with   no  circular  dependencies),      a circular   dependency      between    bean\n               A and bean B forces one of the beans to be injected into the other prior to being fully\n               initialized   itself  (a  classic  chicken-and-egg   scenario).\n\n\n\n            You can generally trust Spring to do the right thing. It detects configuration problems, such as\n            references to non-existent beans and circular dependencies, at container load-time. Spring sets\n            properties    and  resolves    dependencies      as late  as  possible,   when    the  bean   is actually   created.   This\n            means    that a  Spring   container    that  has  loaded   correctly   can  later  generate    an  exception    when    you\n            request an object if there is a problem creating that object or one of its dependencies — for\n            example,    the bean   throws    an  exception    as a  result  of a missing   or  invalid   property.   This  potentially\n            delayed visibility of some configuration issues is why ApplicationContext implementations by\n            default pre-instantiate singleton beans. At the cost of some upfront time and memory to create\n            these   beans    before    they    are   actually   needed,     you    discover    configuration      issues   when     the\n            ApplicationContext      is created,  not  later. You   can  still  override  this default   behavior    so that  singleton\n            beans   initialize lazily, rather   than  being   eagerly   pre-instantiated.\n\n\n            If  no circular  dependencies      exist,  when    one  or  more   collaborating     beans   are  being   injected   into  a\n            dependent bean, each collaborating bean is totally configured prior to being injected into the\n            dependent     bean.  This   means    that, if bean   A  has  a dependency      on  bean   B, the  Spring   IoC  container\n            completely    configures    bean    B prior   to invoking    the  setter  method     on  bean   A. In  other   words,   the\n            bean is instantiated (if it is not a pre-instantiated singleton), its dependencies are set, and the\n            relevant lifecycle methods (such as a configured init method or the InitializingBean callback\n            method)    are  invoked.\n\n\n\n            Examples   of Dependency     Injection\n\n            The  following    example    uses  XML-based      configuration     metadata     for setter-based    DI. A  small   part  of\n            a Spring   XML   configuration     file specifies  some   bean   definitions   as  follows:\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <!--   setter   injection     using   the   nested   ref   element    -->\n                    <property     name=\"beanOne\">\n                         <ref   bean=\"anotherExampleBean\"/>\n                    </property>\n\n\n                    <!--   setter   injection     using   the   neater   ref   attribute     -->\n                    <property     name=\"beanTwo\"      ref=\"yetAnotherBean\"/>\n                    <property     name=\"integerProperty\"         value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    private    AnotherBean     beanOne;\n\n\n                    private    YetAnotherBean      beanTwo;\n\n\n                    private    int  i;\n\n\n                    public   void   setBeanOne(AnotherBean          beanOne)    {\n                         this.beanOne      =  beanOne;\n                    }\n\n\n                    public   void   setBeanTwo(YetAnotherBean           beanTwo)    {\n                         this.beanTwo      =  beanTwo;\n                    }\n\n\n                    public   void   setIntegerProperty(int          i)  {\n                         this.i    =  i;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     {\n                    lateinit    var   beanOne:    AnotherBean\n                    lateinit    var   beanTwo:    YetAnotherBean\n                    var  i:  Int   =  0\n              }\n\n\n\n            In the  preceding    example,    setters  are  declared    to match   against   the  properties    specified  in  the XML\n\n            file.  The  following  example    uses  constructor-based       DI:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <!--   constructor     injection     using   the   nested   ref   element    -->\n                    <constructor-arg>\n                         <ref   bean=\"anotherExampleBean\"/>\n                    </constructor-arg>\n\n\n                    <!--   constructor     injection     using   the   neater   ref   attribute     -->\n                    <constructor-arg       ref=\"yetAnotherBean\"/>\n\n\n                    <constructor-arg       type=\"int\"     value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    private    AnotherBean     beanOne;\n\n\n                    private    YetAnotherBean      beanTwo;\n\n\n                    private    int  i;\n\n\n                    public   ExampleBean(\n                         AnotherBean      anotherBean,      YetAnotherBean      yetAnotherBean,       int   i)  {\n                         this.beanOne      =  anotherBean;\n                         this.beanTwo      =  yetAnotherBean;\n                         this.i    =  i;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean(\n                         private    val   beanOne:    AnotherBean,\n                         private    val   beanTwo:    YetAnotherBean,\n                         private    val   i:  Int)\n\n\n\n            The constructor arguments specified in the bean definition are used as arguments to the\n            constructor    of the  ExampleBean.\n\n\n            Now   consider    a variant   of this  example,    where,   instead   of using   a constructor,    Spring   is told  to call\n            a static  factory   method    to return   an  instance   of the  object:\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\"            factory-method=\"createInstance\">\n                    <constructor-arg       ref=\"anotherExampleBean\"/>\n                    <constructor-arg       ref=\"yetAnotherBean\"/>\n                    <constructor-arg       value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    //  a  private    constructor\n                    private    ExampleBean(...)       {\n                         ...\n                    }\n\n\n                    //  a  static   factory    method;    the   arguments     to  this   method   can   be\n                    //  considered     the   dependencies     of   the  bean   that   is  returned,\n                    //  regardless     of  how   those   arguments     are  actually     used.\n                    public   static    ExampleBean      createInstance      (\n                         AnotherBean      anotherBean,      YetAnotherBean      yetAnotherBean,       int   i)  {\n\n\n                         ExampleBean      eb  =  new  ExampleBean      (...);\n                         //  some   other    operations...\n                         return    eb;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     private    constructor()      {\n                    companion     object   {\n                         //  a  static    factory    method;    the  arguments     to  this   method    can  be\n                         //  considered      the  dependencies      of  the   bean  that   is  returned,\n                         //  regardless      of  how  those   arguments     are   actually    used.\n                         @JvmStatic\n                         fun   createInstance(anotherBean:           AnotherBean,      yetAnotherBean:       YetAnotherBean,\n              i:  Int):    ExampleBean     {\n                               val  eb  =  ExampleBean      (...)\n                               //  some   other   operations...\n                               return   eb\n                         }\n                    }\n              }\n\n            Arguments     to  the  static   factory  method     are  supplied    by  <constructor-arg/>      elements,    exactly   the\n            same   as if a constructor    had   actually   been  used.   The  type  of  the class  being   returned    by  the factory\n            method    does   not  have   to be  of  the same    type  as  the  class  that  contains   the  static   factory   method\n            (although, in this example, it is). An instance (non-static) factory method can be used in an\n            essentially   identical   fashion   (aside  from    the  use  of the  factory-bean     attribute   instead   of  the  class\n            attribute),  so we   do not  discuss   those  details  here.\n\n\n            Dependencies       and  Configuration       in Detail\n\n            As mentioned      in the previous    section,  you   can  define  bean   properties    and  constructor    arguments      as\n            references    to other  managed      beans   (collaborators)    or  as values   defined    inline. Spring’s   XML-based\n            configuration     metadata    supports    sub-element      types  within   its <property/>     and   <constructor-arg/>\n            elements    for this purpose.\n\n\n\n            Straight Values  (Primitives,  Strings,  and  so on)\n\n            The  value   attribute   of the  <property/>     element    specifies   a property    or  constructor     argument     as  a\n            human-readable       string  representation.      Spring’s   conversion    service   is used   to convert    these  values\n            from   a String  to  the actual   type  of the  property    or argument.     The  following    example    shows    various\n            values  being   set:\n\n\n\n              <bean    id=\"myDataSource\"       class=\"org.apache.commons.dbcp.BasicDataSource\"                   destroy-\n              method=\"close\">\n                    <!--   results    in  a  setDriverClassName(String)           call   -->\n                    <property     name=\"driverClassName\"         value=\"com.mysql.jdbc.Driver\"/>\n                    <property     name=\"url\"     value=\"jdbc:mysql://localhost:3306/mydb\"/>\n                    <property     name=\"username\"       value=\"root\"/>\n                    <property     name=\"password\"       value=\"misterkaoli\"/>\n              </bean>\n\n\n\n            The  following   example     uses  the  p-namespace      for even   more   succinct   XML   configuration:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                    https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"myDataSource\"        class=\"org.apache.commons.dbcp.BasicDataSource\"\n                         destroy-method=\"close\"\n                         p:driverClassName=\"com.mysql.jdbc.Driver\"\n                         p:url=\"jdbc:mysql://localhost:3306/mydb\"\n                         p:username=\"root\"\n                         p:password=\"misterkaoli\"/>\n\n\n              </beans>\n\n\n\n            The  preceding    XML    is more   succinct.   However,     typos  are  discovered     at runtime    rather   than  design\n\n            time, unless you use an IDE (such as IntelliJ IDEA or the Spring Tools for Eclipse) that supports\n            automatic property completion when you create bean definitions. Such IDE assistance is highly\n            recommended.\n\n\n            You  can  also  configure   a  java.util.Properties      instance,   as  follows:\n\n\n\n              <bean    id=\"mappings\"\n                    class=\"org.springframework.context.support.PropertySourcesPlaceholderConfigurer\">\n\n\n                    <!--   typed   as  a  java.util.Properties         -->\n                    <property     name=\"properties\">\n                         <value>\n                               jdbc.driver.className=com.mysql.jdbc.Driver\n                               jdbc.url=jdbc:mysql://localhost:3306/mydb\n                         </value>\n                    </property>\n              </bean>\n\n\n\n            The Spring container converts the text inside the <value/> element into a java.util.Properties\n            instance   by  using  the  JavaBeans     PropertyEditor     mechanism.      This  is a  nice  shortcut,   and  is one  of  a\n            few  places   where    the  Spring   team   do  favor   the  use  of the  nested    <value/>   element    over   the  value\n            attribute  style.\n\n\n            The  idref  element\n\n            The  idref   element    is simply   an  error-proof    way   to  pass  the  id (a  string  value   -  not a reference)    of\n            another bean in the container to a <constructor-arg/> or <property/> element. The following\n            example    shows   how    to use  it:\n\n\n\n              <bean    id=\"theTargetBean\"        class=\"...\"/>\n\n\n              <bean    id=\"theClientBean\"        class=\"...\">\n                    <property     name=\"targetName\">\n                         <idref    bean=\"theTargetBean\"/>\n                    </property>\n              </bean>\n\n\n\n            The  preceding    bean   definition   snippet   is exactly  equivalent    (at runtime)    to the  following   snippet:\n\n\n\n              <bean    id=\"theTargetBean\"        class=\"...\"     />\n\n\n              <bean    id=\"client\"     class=\"...\">\n                    <property     name=\"targetName\"       value=\"theTargetBean\"/>\n              </bean>\n\n\n\n            The  first form   is preferable    to the  second,   because    using  the  idref   tag lets the  container    validate   at\n            deployment time that the referenced, named bean actually exists. In the second variation, no\n\n            validation   is performed      on  the  value   that is passed    to the  targetName    property    of  the  client  bean.\n            Typos are only discovered (with most likely fatal results) when the client bean is actually\n            instantiated.   If the  client  bean   is a  prototype    bean,  this  typo  and   the  resulting   exception    may   only\n            be discovered     long  after the  container    is  deployed.\n\n\n                              The  local   attribute   on  the  idref   element    is no  longer   supported     in the  4.0  beans\n                              XSD, since it does not provide value over a regular bean reference any more.\n                             Change    your  existing   idref   local   references    to idref   bean  when    upgrading     to the\n                              4.0 schema.\n\n\n            A common      place   (at least  in  versions   earlier   than   Spring   2.0)  where    the  <idref/>   element    brings\n            value is in the configuration of AOP interceptors in a ProxyFactoryBean bean definition. Using\n            <idref/> elements when you specify the interceptor names prevents you from misspelling an\n            interceptor   ID.\n\n\n\n            References   to Other  Beans  (Collaborators)\n\n            The  ref  element    is the  final element    inside   a <constructor-arg/>      or  <property/>    definition   element.\n            Here, you set the value of the specified property of a bean to be a reference to another bean (a\n            collaborator)    managed     by  the  container.    The  referenced     bean   is a  dependency      of the  bean   whose\n            property    is to be  set, and   it is initialized   on  demand     as  needed    before   the  property    is set. (If the\n            collaborator    is a singleton    bean,  it may   already    be  initialized  by  the  container.)    All references    are\n            ultimately   a reference    to another    object.  Scoping   and   validation   depend    on  whether    you   specify  the\n            ID or  name   of the  other   object  through    the bean  or  parent  attribute.\n\n\n            Specifying   the  target  bean   through    the  bean  attribute   of the  <ref/>  tag  is the most   general    form  and\n            allows  creation    of a reference    to any   bean   in the  same   container    or parent    container,   regardless    of\n            whether it is in the same XML file. The value of the bean attribute may be the same as the id\n            attribute   of the  target  bean   or  be  the  same   as  one   of the  values   in the  name   attribute   of the  target\n            bean.  The  following    example    shows    how   to use  a ref  element:\n\n\n\n              <ref   bean=\"someBean\"/>\n\n\n\n            Specifying    the  target  bean   through    the  parent   attribute   creates   a  reference    to a  bean   that  is in  a\n            parent container of the current container. The value of the parent attribute may be the same as\n            either  the id  attribute  of  the target  bean   or  one  of the  values   in the  name  attribute  of  the target  bean.\n            The target bean must be in a parent container of the current one. You should use this bean\n            reference variant mainly when you have a hierarchy of containers and you want to wrap an\n            existing  bean   in  a parent   container    with   a proxy    that  has  the  same   name    as  the  parent   bean.   The\n            following   pair  of listings  shows   how   to use  the  parent   attribute:\n\n\n\n              <!--   in  the   parent   context    -->\n              <bean    id=\"accountService\"        class=\"com.something.SimpleAccountService\">\n                    <!--   insert   dependencies      as  required     here   -->\n              </bean>\n\n              <!--   in  the   child   (descendant)      context    -->\n              <bean    id=\"accountService\"        <!--   bean   name   is  the  same   as  the   parent   bean   -->\n                    class=\"org.springframework.aop.framework.ProxyFactoryBean\">\n                    <property     name=\"target\">\n                         <ref   parent=\"accountService\"/>           <!--   notice   how   we  refer   to  the   parent    bean  -->\n                    </property>\n                    <!--   insert   other    configuration      and  dependencies      as  required     here   -->\n              </bean>\n\n\n\n\n                              The  local  attribute   on  the  ref element    is no  longer   supported    in the  4.0 beans    XSD,\n                             since it does not provide value over a regular bean reference any more. Change\n                              your  existing   ref  local  references    to ref  bean  when    upgrading     to the 4.0  schema.\n\n\n\n            Inner Beans\n\n            A <bean/>   element    inside   the  <property/>    or  <constructor-arg/>      elements    defines   an  inner   bean,   as\n            the following    example    shows:\n\n\n\n              <bean    id=\"outer\"     class=\"...\">\n                    <!--   instead    of  using   a  reference     to  a target    bean,   simply    define    the  target    bean\n              inline    -->\n                    <property     name=\"target\">\n                         <bean    class=\"com.example.Person\">           <!--   this   is  the  inner    bean   -->\n                               <property     name=\"name\"     value=\"Fiona      Apple\"/>\n                               <property     name=\"age\"     value=\"25\"/>\n                         </bean>\n                    </property>\n              </bean>\n\n\n\n            An  inner  bean   definition   does   not  require   a defined   ID  or name.    If specified,  the  container    does  not\n            use such a value as an identifier. The container also ignores the scope flag on creation, because\n            inner  beans   are  always   anonymous       and  are  always    created   with  the  outer  bean.   It  is  not  possible  to\n            access inner beans independently or to inject them into collaborating beans other than into the\n            enclosing   bean.\n\n\n            As a  corner   case,  it  is  possible  to  receive  destruction  callbacks    from   a custom    scope — for    example,\n            for a request-scoped      inner   bean   contained    within   a singleton    bean.  The   creation   of  the inner   bean\n            instance is tied to its containing bean, but destruction callbacks let it participate in the request\n            scope’s  lifecycle.  This  is  not  a common    scenario.   Inner   beans   typically  simply   share   their  containing\n            bean’s  scope.\n\n\n\n            Collections\n\n            The <list/>, <set/>, <map/>, and <props/> elements set the properties and arguments of the Java\n            Collection    types  List,  Set,  Map, and   Properties,    respectively.   The   following    example     shows   how    to\n            use them:\n\n              <bean    id=\"moreComplexObject\"         class=\"example.ComplexObject\">\n                    <!--   results    in  a  setAdminEmails(java.util.Properties)              call   -->\n                    <property     name=\"adminEmails\">\n                         <props>\n                               <prop   key=\"administrator\">administrator@example.org</prop>\n                               <prop   key=\"support\">support@example.org</prop>\n                               <prop   key=\"development\">development@example.org</prop>\n                         </props>\n                    </property>\n                    <!--   results    in  a  setSomeList(java.util.List)           call   -->\n                    <property     name=\"someList\">\n                         <list>\n                               <value>a    list   element    followed    by   a reference</value>\n                               <ref   bean=\"myDataSource\"        />\n                         </list>\n                    </property>\n                    <!--   results    in  a  setSomeMap(java.util.Map)          call   -->\n                    <property     name=\"someMap\">\n                         <map>\n                               <entry   key=\"an    entry\"    value=\"just      some  string\"/>\n                               <entry   key=\"a    ref\"   value-ref=\"myDataSource\"/>\n                         </map>\n                    </property>\n                    <!--   results    in  a  setSomeSet(java.util.Set)          call   -->\n                    <property     name=\"someSet\">\n                         <set>\n                               <value>just     some   string</value>\n                               <ref   bean=\"myDataSource\"        />\n                         </set>\n                    </property>\n              </bean>\n\n\n\n            The  value  of  a map   key  or  value,  or a set  value,  can  also  be any  of  the following    elements:\n\n\n\n              bean   |  ref  |  idref   |  list   |  set  |  map   | props    | value    | null\n\n\n\n            Collection    Merging\n\n            The Spring container also supports merging collections. An application developer can define a\n            parent   <list/>,  <map/>,  <set/>   or  <props/>   element    and  have   child  <list/>,  <map/>,   <set/>  or  <props/>\n            elements inherit and override values from the parent collection. That is, the child collection’s\n            values   are  the  result  of merging     the  elements    of the  parent    and  child   collections,   with  the  child’s\n            collection  elements    overriding    values   specified   in the  parent   collection.\n\n\n            This section on merging discusses the parent-child bean mechanism. Readers unfamiliar with\n            parent   and  child  bean   definitions   may   wish   to read  the  relevant   section   before  continuing.\n\n\n            The  following   example     demonstrates     collection   merging:\n\n              <beans>\n                    <bean   id=\"parent\"      abstract=\"true\"       class=\"example.ComplexObject\">\n                         <property     name=\"adminEmails\">\n                               <props>\n                                    <prop    key=\"administrator\">administrator@example.com</prop>\n                                    <prop    key=\"support\">support@example.com</prop>\n                               </props>\n                         </property>\n                    </bean>\n                    <bean   id=\"child\"     parent=\"parent\">\n                         <property     name=\"adminEmails\">\n                               <!--   the  merge   is   specified    on  the   child   collection     definition     -->\n                               <props   merge=\"true\">\n                                    <prop    key=\"sales\">sales@example.com</prop>\n                                    <prop    key=\"support\">support@example.co.uk</prop>\n                               </props>\n                         </property>\n                    </bean>\n              <beans>\n\n\n\n            Notice  the  use  of the  merge=true    attribute  on  the  <props/>   element    of the  adminEmails    property    of the\n            child bean definition. When the child bean is resolved and instantiated by the container, the\n            resulting   instance   has  an  adminEmails     Properties    collection   that  contains   the  result  of  merging    the\n            child’s  adminEmails    collection   with   the  parent’s   adminEmails    collection.   The   following    listing shows\n            the result:\n\n\n\n              administrator=administrator@example.com\n              sales=sales@example.com\n              support=support@example.co.uk\n\n\n\n            The  child  Properties    collection’s   value   set inherits   all property    elements    from   the  parent   <props/>,\n            and  the  child’s value   for the  support   value  overrides    the  value  in  the parent   collection.\n\n\n            This  merging    behavior     applies   similarly   to the  <list/>,   <map/>,   and  <set/>   collection   types.   In the\n            specific  case  of the  <list/>   element,    the  semantics    associated    with   the List   collection   type  (that  is,\n            the notion    of an  ordered   collection   of  values)  is maintained.     The   parent’s   values   precede    all of the\n            child list’s values. In the case of the Map, Set, and Properties collection types, no ordering exists.\n            Hence,   no  ordering    semantics    are  in effect  for  the collection   types   that  underlie   the  associated    Map,\n            Set, and  Properties    implementation       types  that  the container    uses  internally.\n\n\n            Limitations     of Collection    Merging\n\n            You  cannot   merge    different   collection  types   (such  as  a Map and   a List).  If  you do  attempt   to do  so, an\n            appropriate    Exception    is  thrown.  The  merge   attribute  must   be  specified   on  the lower,   inherited,   child\n            definition.  Specifying    the  merge  attribute   on a  parent   collection  definition    is  redundant   and   does  not\n            result in  the desired   merging.\n\n            Strongly-typed      collection\n\n            Thanks to Java’s support for generic types, you can use strongly typed collections. That is, it is\n            possible   to declare   a Collection    type  such   that  it  can  only contain   (for example)     String   elements.   If\n            you use Spring to dependency-inject a strongly-typed Collection into a bean, you can take\n            advantage of Spring’s type-conversion support such that the elements of your strongly-typed\n            Collection    instances   are  converted     to the  appropriate     type  prior  to  being   added   to  the Collection.\n            The  following   Java   class and   bean  definition   show    how   to do  so:\n\n\n            Java\n\n\n              public    class   SomeClass     {\n\n\n                    private    Map<String,     Float>    accounts;\n\n\n                    public   void   setAccounts(Map<String,          Float>    accounts)     {\n                         this.accounts       = accounts;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    SomeClass    {\n                    lateinit    var   accounts:    Map<String,      Float>\n              }\n\n\n\n\n              <beans>\n                    <bean   id=\"something\"       class=\"x.y.SomeClass\">\n                         <property     name=\"accounts\">\n                               <map>\n                                    <entry    key=\"one\"     value=\"9.99\"/>\n                                    <entry    key=\"two\"     value=\"2.75\"/>\n                                    <entry    key=\"six\"     value=\"3.99\"/>\n                               </map>\n                         </property>\n                    </bean>\n              </beans>\n\n\n\n            When     the   accounts    property     of  the   something     bean    is  prepared     for   injection,   the   generics\n            information about the element type of the strongly-typed Map<String, Float> is available by\n            reflection.  Thus,   Spring’s   type  conversion     infrastructure     recognizes    the  various    value  elements     as\n            being  of  type  Float,  and   the  string  values   (9.99,  2.75,  and  3.99)   are  converted    into  an  actual   Float\n            type.\n\n\n\n            Null and  Empty   String Values\n\n            Spring   treats  empty    arguments     for  properties    and   the  like  as empty    Strings.   The   following    XML-\n            based   configuration    metadata     snippet   sets the  email  property    to the empty    String   value  (\"\").\n\n              <bean    class=\"ExampleBean\">\n                    <property     name=\"email\"     value=\"\"/>\n              </bean>\n\n\n\n            The  preceding    example    is equivalent    to the  following    Java  code:\n\n\n            Java\n\n\n              exampleBean.setEmail(\"\");\n\n\n\n            Kotlin\n\n\n              exampleBean.email        =  \"\"\n\n\n\n            The  <null/>   element    handles   null  values.  The   following   listing  shows   an  example:\n\n\n\n              <bean    class=\"ExampleBean\">\n                    <property     name=\"email\">\n                         <null/>\n                    </property>\n              </bean>\n\n\n\n            The  preceding    configuration     is  equivalent   to the following    Java  code:\n\n\n            Java\n\n\n              exampleBean.setEmail(null);\n\n\n\n            Kotlin\n\n\n              exampleBean.email        =  null\n\n\n\n\n            XML  Shortcut   with  the p-namespace\n\n            The  p-namespace      lets you   use  the bean  element’s    attributes   (instead   of nested   <property/>    elements)\n            to describe   your   property   values   collaborating    beans,   or both.\n\n\n            Spring supports extensible configuration formats with namespaces, which are based on an XML\n            Schema    definition.   The   beans  configuration     format    discussed    in this  chapter   is defined    in an  XML\n            Schema    document.     However,     the  p-namespace       is not  defined   in  an  XSD   file and  exists  only   in the\n            core  of Spring.\n\n\n            The following example shows two XML snippets (the first uses standard XML format and the\n            second   uses  the  p-namespace)      that resolve   to the  same   result:\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   name=\"classic\"       class=\"com.example.ExampleBean\">\n                         <property     name=\"email\"      value=\"someone@somewhere.com\"/>\n                    </bean>\n\n\n                    <bean   name=\"p-namespace\"        class=\"com.example.ExampleBean\"\n                         p:email=\"someone@somewhere.com\"/>\n              </beans>\n\n\n\n            The  example     shows    an  attribute   in the  p-namespace       called  email  in  the  bean   definition.   This  tells\n            Spring   to include   a property    declaration.    As  previously    mentioned,     the p-namespace       does  not  have\n            a schema    definition,   so you  can  set  the name    of the  attribute   to the property    name.\n\n\n            This  next  example    includes   two   more   bean   definitions   that  both  have   a reference    to another   bean:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   name=\"john-classic\"         class=\"com.example.Person\">\n                         <property     name=\"name\"      value=\"John     Doe\"/>\n                         <property     name=\"spouse\"      ref=\"jane\"/>\n                    </bean>\n\n\n                    <bean   name=\"john-modern\"\n                         class=\"com.example.Person\"\n                         p:name=\"John      Doe\"\n                         p:spouse-ref=\"jane\"/>\n\n\n                    <bean   name=\"jane\"      class=\"com.example.Person\">\n                         <property     name=\"name\"      value=\"Jane     Doe\"/>\n                    </bean>\n              </beans>\n\n\n\n            This example includes not only a property value using the p-namespace but also uses a special\n            format    to   declare    property     references.     Whereas       the   first  bean    definition     uses   <property\n            name=\"spouse\" ref=\"jane\"/> to create a reference from bean john to bean jane, the second bean\n            definition   uses  p:spouse-ref=\"jane\"       as an  attribute   to do  the exact   same   thing.  In this  case,  spouse  is\n            the property name, whereas the -ref part indicates that this is not a straight value but rather a\n            reference   to another    bean.\n\n                              The  p-namespace       is  not  as  flexible  as  the  standard  XML    format.   For  example,    the\n                              format   for  declaring    property    references    clashes   with   properties   that  end   in  Ref,\n                             whereas    the  standard    XML   format    does  not.  We   recommend       that  you  choose   your\n                              approach     carefully    and    communicate        this  to   your   team    members       to  avoid\n                              producing    XML    documents     that  use  all  three approaches     at the  same   time.\n\n\n\n            XML  Shortcut   with  the c-namespace\n\n            Similar to the XML Shortcut with the p-namespace, the c-namespace, introduced in Spring 3.1,\n            allows  inlined   attributes   for configuring     the constructor    arguments      rather  then   nested   constructor-\n            arg elements.\n\n\n            The  following    example    uses   the  c: namespace      to do  the  same    thing  as the  from   Constructor-based\n            Dependency      Injection:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:c=\"http://www.springframework.org/schema/c\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"beanTwo\"      class=\"x.y.ThingTwo\"/>\n                    <bean   id=\"beanThree\"       class=\"x.y.ThingThree\"/>\n\n\n                    <!--   traditional     declaration      with   optional    argument    names    -->\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\">\n                         <constructor-arg        name=\"thingTwo\"       ref=\"beanTwo\"/>\n                         <constructor-arg        name=\"thingThree\"       ref=\"beanThree\"/>\n                         <constructor-arg        name=\"email\"      value=\"something@somewhere.com\"/>\n                    </bean>\n\n\n                    <!--   c-namespace     declaration      with   argument    names   -->\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\"         c:thingTwo-ref=\"beanTwo\"\n                         c:thingThree-ref=\"beanThree\"            c:email=\"something@somewhere.com\"/>\n\n\n              </beans>\n\n\n\n            The  c: namespace      uses   the same    conventions     as the  p: one   (a trailing  -ref  for  bean   references)    for\n            setting  the  constructor    arguments     by  their  names.   Similarly,   it needs   to be  declared   in  the  XML   file\n            even  though    it  is  not  defined  in  an  XSD  schema  (it  exists  inside  the  Spring core).\n\n            For the  rare  cases   where   the  constructor    argument     names    are  not  available   (usually   if  the  bytecode\n            was   compiled    without    debugging     information),     you   can  use  fallback   to  the  argument     indexes,    as\n            follows:\n\n              <!--   c-namespace      index   declaration     -->\n              <bean    id=\"beanOne\"     class=\"x.y.ThingOne\"         c:_0-ref=\"beanTwo\"        c:_1-ref=\"beanThree\"\n                    c:_2=\"something@somewhere.com\"/>\n\n\n\n\n                              Due  to  the XML    grammar,     the  index   notation    requires   the  presence    of the  leading\n                              _, as XML attribute names cannot start with a number (even though some IDEs\n                             allow it). A corresponding index notation is also available for <constructor-arg>\n                              elements but not commonly used since the plain order of declaration is usually\n                              sufficient  there.\n\n\n            In practice, the constructor resolution mechanism is quite efficient in matching arguments, so\n            unless  you   really need   to, we  recommend       using   the name    notation   throughout     your   configuration.\n\n\n\n            Compound     Property  Names\n\n            You can use compound or nested property names when you set bean properties, as long as all\n            components      of the  path   except   the  final property    name    are  not   null. Consider    the  following    bean\n            definition:\n\n\n\n              <bean    id=\"something\"      class=\"things.ThingOne\">\n                    <property     name=\"fred.bob.sammy\"         value=\"123\"     />\n              </bean>\n\n\n\n            The  something    bean   has  a fred  property,    which   has  a  bob property,    which   has  a  sammy  property,   and\n            that final  sammy  property    is being  set  to a value   of 123. In  order  for  this to work,   the  fred  property    of\n            something   and   the  bob property    of  fred  must   not  be  null  after  the bean   is constructed.    Otherwise,     a\n            NullPointerException      is thrown.\n\n\n            Using   depends-on\n\n            If  a  bean is  a  dependency    of another    bean,  that  usually   means    that  one  bean   is set as  a property    of\n            another. Typically you accomplish this with the <ref/> element in XML-based configuration\n            metadata.    However,     sometimes     dependencies      between    beans   are  less  direct. An   example    is when    a\n            static initializer in a class needs to be triggered, such as for database driver registration. The\n            depends-on    attribute   can  explicitly  force   one  or  more   beans    to be  initialized  before   the  bean   using\n            this element is initialized. The following example uses the depends-on attribute to express a\n            dependency     on  a single   bean:\n\n\n\n              <bean    id=\"beanOne\"     class=\"ExampleBean\"         depends-on=\"manager\"/>\n              <bean    id=\"manager\"     class=\"ManagerBean\"         />\n\n\n\n            To express    a dependency      on  multiple   beans,   supply   a list  of  bean  names  as  the value   of the  depends-\n            on attribute   (commas,    whitespace,     and  semicolons     are valid  delimiters):\n\n              <bean    id=\"beanOne\"     class=\"ExampleBean\"         depends-on=\"manager,accountDao\">\n                    <property     name=\"manager\"      ref=\"manager\"      />\n              </bean>\n\n\n              <bean    id=\"manager\"     class=\"ManagerBean\"         />\n              <bean    id=\"accountDao\"       class=\"x.y.jdbc.JdbcAccountDao\"             />\n\n\n\n\n                              The  depends-on    attribute  can   specify  both   an initialization-time     dependency      and,  in\n                              the case of singleton beans only, a corresponding destruction-time dependency.\n                             Dependent beans that define a depends-on relationship with a given bean are\n                              destroyed    first,  prior  to  the  given  bean itself being   destroyed.   Thus,   depends-on    can\n                              also control   shutdown     order.\n\n\n\n            Lazy-initialized     Beans\n\n            By  default,  ApplicationContext      implementations       eagerly   create   and  configure    all singleton   beans    as\n            part  of the  initialization  process.   Generally,    this pre-instantiation     is desirable,   because   errors   in the\n            configuration or surrounding environment are discovered immediately, as opposed to hours or\n            even days later. When this behavior is not desirable, you can prevent pre-instantiation of a\n            singleton   bean   by  marking    the  bean   definition   as being   lazy-initialized.   A  lazy-initialized   bean   tells\n            the IoC  container    to create  a bean   instance   when    it is  first  requested, rather   than  at startup.\n\n\n            In XML, this behavior is controlled by the lazy-init attribute on the <bean/> element, as the\n            following   example    shows:\n\n\n\n              <bean    id=\"lazy\"    class=\"com.something.ExpensiveToCreateBean\"                  lazy-init=\"true\"/>\n              <bean    name=\"not.lazy\"       class=\"com.something.AnotherBean\"/>\n\n\n\n            When the preceding configuration is consumed by an ApplicationContext, the lazy bean is not\n            eagerly   pre-instantiated     when    the  ApplicationContext      starts,  whereas    the  not.lazy    bean   is eagerly\n            pre-instantiated.\n\n\n            However, when a lazy-initialized bean is a dependency of a singleton bean that is not lazy-\n            initialized, the ApplicationContext creates the lazy-initialized bean at startup, because it must\n            satisfy the singleton’s dependencies. The lazy-initialized bean is injected into a singleton bean\n            elsewhere    that  is  not  lazy-initialized.\n\n            You can also control lazy-initialization at the container level by using the default-lazy-init\n            attribute  on  the  <beans/>   element,   as  the following    example    shows:\n\n\n\n              <beans    default-lazy-init=\"true\">\n                    <!--   no  beans   will   be  pre-instantiated...         -->\n              </beans>\n\n            Autowiring     Collaborators\n\n            The  Spring   container    can   autowire    relationships     between    collaborating     beans.   You  can   let Spring\n            resolve   collaborators    (other   beans)   automatically     for  your   bean   by  inspecting    the  contents    of the\n            ApplicationContext.      Autowiring    has  the  following    advantages:\n\n              • Autowiring can significantly reduce the need to specify properties or constructor arguments.\n                (Other mechanisms such as a bean template discussed elsewhere in this chapter are also\n                valuable    in this regard.)\n\n              • Autowiring     can  update    a configuration    as  your  objects   evolve.  For  example,    if you  need   to add   a\n                dependency      to  a class,  that dependency       can  be  satisfied  automatically     without    you   needing    to\n                modify the configuration. Thus autowiring can be especially useful during development,\n                without    negating    the option   of  switching    to explicit  wiring    when    the code   base   becomes     more\n                stable.\n\n\n            When using XML-based configuration metadata (see Dependency Injection), you can specify the\n            autowire mode for a bean definition with the autowire attribute of the <bean/> element. The\n            autowiring functionality has four modes. You specify autowiring per bean and can thus choose\n            which   ones  to  autowire.   The   following   table  describes   the  four  autowiring     modes:\n\n\n            Table 2. Autowiring    modes\n\n            Mode                     Explanation\n            no                       (Default)   No  autowiring.    Bean   references    must   be  defined   by  ref elements.\n                                     Changing     the default   setting  is not  recommended       for  larger  deployments,\n                                     because    specifying   collaborators     explicitly  gives  greater   control  and   clarity. To\n                                     some    extent,  it  documents    the structure   of  a system.\n            byName                   Autowiring     by  property    name.   Spring   looks  for a  bean  with   the same    name   as\n                                     the  property    that needs   to be  autowired.    For  example,    if a bean   definition   is\n                                     set to  autowire    by name    and  it contains   a master   property    (that is, it  has  a\n                                     setMaster(..)     method),    Spring   looks  for a  bean  definition   named     master  and\n                                     uses  it to set the  property.\n            byType                   Lets  a property    be  autowired    if exactly  one   bean  of  the property    type  exists  in\n                                     the  container.   If more   than   one  exists, a  fatal exception    is  thrown,  which\n                                     indicates   that  you  may   not  use  byType   autowiring    for that  bean.   If  there are no\n                                     matching     beans,  nothing    happens    (the  property   is not  set).\n            constructor              Analogous     to byType   but  applies  to constructor    arguments.     If there  is not\n                                     exactly   one  bean   of the  constructor    argument     type  in the  container,   a fatal\n                                     error   is  raised.\n\n\n            With byType or constructor autowiring mode, you can wire arrays and typed collections. In such\n            cases,  all autowire    candidates     within   the  container    that  match    the  expected    type  are  provided     to\n            satisfy  the  dependency.     You   can  autowire     strongly-typed     Map  instances   if the  expected    key   type  is\n            String. An autowired Map instance’s values consist of all bean instances that match the expected\n            type, and   the Map  instance’s   keys  contain   the  corresponding      bean   names.\n\n            Limitations  and  Disadvantages    of Autowiring\n\n            Autowiring works best when it is used consistently across a project. If autowiring is not used in\n            general,  it might   be confusing    to developers     to use  it  to  wire  only  one  or  two  bean definitions.\n\n\n            Consider   the  limitations   and   disadvantages     of autowiring:\n\n              • Explicit  dependencies      in  property   and  constructor-arg      settings  always    override   autowiring.     You\n                cannot    autowire    simple   properties    such  as  primitives,   Strings,   and   Classes   (and  arrays   of such\n                simple   properties).   This  limitation   is by-design.\n\n              • Autowiring     is less  exact  than   explicit  wiring.   Although,    as  noted   in  the  earlier  table,  Spring   is\n                careful to avoid guessing in case of ambiguity that might have unexpected results. The\n                relationships    between    your   Spring-managed       objects   are  no longer   documented      explicitly.\n\n              • Wiring information may not be available to tools that may generate documentation from a\n                Spring   container.\n\n              • Multiple bean definitions within the container may match the type specified by the setter\n                method    or  constructor    argument     to be  autowired.    For  arrays,  collections,   or Map  instances,   this is\n                not  necessarily    a problem.    However,     for dependencies      that  expect   a single  value,  this  ambiguity\n                is not  arbitrarily  resolved.   If no  unique   bean   definition   is available,   an  exception   is thrown.\n\n\n            In the  latter scenario,   you  have   several   options:\n\n              • Abandon     autowiring     in favor  of explicit  wiring.\n\n              • Avoid   autowiring     for  a bean   definition    by  setting  its autowire-candidate       attributes   to false,   as\n                described    in the  next  section.\n\n              • Designate    a single  bean   definition   as the  primary    candidate    by  setting  the  primary  attribute   of its\n                <bean/>   element    to true.\n\n              • Implement the more fine-grained control available with annotation-based configuration, as\n                described    in Annotation-based       Container    Configuration.\n\n\n\n            Excluding   a  Bean from  Autowiring\n\n            On a per-bean basis, you can exclude a bean from autowiring. In Spring’s XML format, set the\n            autowire-candidate      attribute   of the  <bean/>  element    to false.  The   container    makes   that  specific  bean\n            definition   unavailable     to the  autowiring     infrastructure     (including   annotation     style  configurations\n            such  as @Autowired).\n\n\n                              The  autowire-candidate       attribute   is designed    to only  affect  type-based     autowiring.\n                              It does not affect explicit references by name, which get resolved even if the\n                             specified bean is not marked as an autowire candidate. As a consequence,\n                              autowiring    by  name    nevertheless    injects  a bean   if  the  name  matches.\n\n\n            You can also limit autowire candidates based on pattern-matching against bean names. The top-\n            level <beans/> element accepts one or more patterns within its default-autowire-candidates\n            attribute. For example, to limit autowire candidate status to any bean whose name ends with\n            Repository,   provide    a value   of *Repository.    To  provide    multiple   patterns,   define   them   in  a comma-\n            separated    list.  An  explicit  value of true  or  false  for  a bean   definition’s   autowire-candidate      attribute\n\n            always   takes  precedence.     For  such  beans,   the pattern   matching     rules  do  not apply.\n\n\n            These techniques are useful for beans that you never want to be injected into other beans by\n            autowiring. It does not mean that an excluded bean cannot itself be configured by using\n            autowiring.    Rather,   the bean   itself is not a  candidate    for autowiring    other   beans.\n\n\n            Method    Injection\n\n            In most   application    scenarios,    most   beans   in the  container    are   singletons.   When    a  singleton   bean\n            needs   to collaborate    with  another    singleton   bean   or a  non-singleton     bean   needs   to collaborate    with\n            another non-singleton bean, you typically handle the dependency by defining one bean as a\n            property    of the  other.  A  problem     arises  when    the  bean   lifecycles   are  different.  Suppose     singleton\n            bean   A  needs   to use   non-singleton     (prototype)    bean   B, perhaps     on  each   method    invocation     on  A.\n            The  container    creates   the singleton    bean   A only  once,   and  thus   only  gets  one  opportunity     to set the\n            properties.   The   container    cannot   provide    bean   A  with  a  new   instance   of  bean   B every   time   one  is\n            needed.\n\n            A solution   is to  forego   some   inversion    of control.   You  can   make   bean   A  aware    of the  container    by\n            implementing the ApplicationContextAware interface, and by making a getBean(\"B\") call to the\n            container ask for (a typically new) bean B instance every time bean A needs it. The following\n            example    shows   this  approach:\n\n            Java\n\n\n              //  a  class   that   uses   a  stateful    Command-style       class   to  perform    some   processing\n              package    fiona.apple;\n\n\n              //  Spring-API      imports\n              import    org.springframework.beans.BeansException;\n              import    org.springframework.context.ApplicationContext;\n              import    org.springframework.context.ApplicationContextAware;\n\n\n              public    class   CommandManager       implements     ApplicationContextAware          {\n\n\n                    private    ApplicationContext        applicationContext;\n\n\n                    public   Object    process(Map      commandState)      {\n                         //  grab   a  new   instance    of  the   appropriate     Command\n                         Command    command    =  createCommand();\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    protected     Command    createCommand()       {\n                         //  notice    the   Spring   API   dependency!\n                         return    this.applicationContext.getBean(\"command\",                 Command.class);\n                    }\n\n\n                    public   void   setApplicationContext(\n                               ApplicationContext        applicationContext)        throws    BeansException       {\n                         this.applicationContext          =  applicationContext;\n                    }\n              }\n\n            Kotlin\n\n\n              //  a  class   that   uses   a  stateful    Command-style       class   to  perform    some   processing\n              package    fiona.apple\n\n\n              //  Spring-API      imports\n              import    org.springframework.context.ApplicationContext\n              import    org.springframework.context.ApplicationContextAware\n\n\n              class    CommandManager      :  ApplicationContextAware          {\n\n\n                    private    lateinit    var   applicationContext:        ApplicationContext\n\n\n                    fun  process(commandState:          Map<*,   *>):   Any   {\n                         //  grab   a  new   instance    of  the   appropriate     Command\n                         val   command    =  createCommand()\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    //  notice    the  Spring    API  dependency!\n                    protected     fun  createCommand()       =\n                               applicationContext.getBean(\"command\",               Command::class.java)\n\n\n                    override    fun   setApplicationContext(applicationContext:                ApplicationContext)         {\n                         this.applicationContext          =  applicationContext\n                    }\n              }\n\n\n\n            The preceding is not desirable, because the business code is aware of and coupled to the Spring\n            Framework.      Method    Injection,   a somewhat      advanced     feature   of  the  Spring   IoC  container,   lets  you\n            handle   this use  case  cleanly.\n\n\n\n               You   can  read  more   about   the  motivation    for  Method    Injection   in this blog  entry.\n\n\n\n\n\n            Lookup   Method   Injection\n\n            Lookup    method    injection   is the  ability of  the  container   to  override   methods     on  container-managed\n            beans   and  return   the  lookup    result  for another    named     bean   in the  container.    The  lookup    typically\n            involves a prototype bean, as in the scenario described in the preceding section. The Spring\n            Framework      implements     this  method    injection   by  using  bytecode    generation    from   the  CGLIB    library\n            to dynamically     generate   a  subclass   that overrides    the  method.\n\n                                • For  this  dynamic    subclassing    to  work,   the  class that  the  Spring   bean   container\n                                  subclasses    cannot   be  final,  and   the  method    to  be  overridden     cannot   be  final,\n                                  either.\n\n                                • Unit-testing    a class  that  has   an  abstract   method     requires    you  to  subclass   the\n                                  class  yourself   and  to supply   a stub  implementation       of the  abstract   method.\n                               • Concrete    methods     are  also necessary     for component      scanning,    which    requires\n                                  concrete   classes   to pick  up.\n\n                                • A further key limitation is that lookup methods do not work with factory\n                                  methods and in particular not with @Bean methods in configuration classes,\n                                  since,  in  that  case, the  container    is not  in  charge   of  creating   the  instance   and\n                                  therefore   cannot    create  a runtime-generated        subclass   on  the fly.\n\n\n            In the case of the CommandManager class in the previous code snippet, the Spring container\n            dynamically     overrides    the implementation       of the  createCommand()      method.    The  CommandManager     class\n            does  not  have   any  Spring   dependencies,     as the  reworked     example    shows:\n\n\n            Java\n\n\n              package    fiona.apple;\n\n\n              //  no   more  Spring    imports!\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         //  grab   a  new   instance    of  the   appropriate     Command    interface\n                         Command    command    =  createCommand();\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    //  okay...    but  where    is  the  implementation       of  this   method?\n                    protected     abstract    Command    createCommand();\n              }\n\n            Kotlin\n\n\n              package    fiona.apple\n\n\n              //  no   more  Spring    imports!\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         //  grab   a  new   instance    of  the   appropriate     Command    interface\n                         val   command    =  createCommand()\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    //  okay...    but  where    is  the  implementation       of  this   method?\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            In the client class that contains the method to be injected (the CommandManager in this case), the\n            method    to be  injected  requires    a signature   of the  following    form:\n\n\n\n              <public|protected>        [abstract]      <return-type>      theMethodName(no-arguments);\n\n\n\n            If  the  method   is abstract,   the  dynamically-generated         subclass   implements      the  method.    Otherwise,\n            the dynamically-generated subclass overrides the concrete method defined in the original class.\n            Consider   the  following    example:\n\n\n\n              <!--   a  stateful    bean   deployed     as  a prototype     (non-singleton)       -->\n              <bean    id=\"myCommand\"      class=\"fiona.apple.AsyncCommand\"              scope=\"prototype\">\n                    <!--   inject   dependencies      here   as  required     -->\n              </bean>\n\n\n              <!--   commandProcessor        uses  statefulCommandHelper          -->\n              <bean    id=\"commandManager\"        class=\"fiona.apple.CommandManager\">\n                    <lookup-method      name=\"createCommand\"         bean=\"myCommand\"/>\n              </bean>\n\n\n\n            The bean identified as commandManager calls its own createCommand() method whenever it needs a\n            new   instance   of the  myCommand   bean.   You  must   be  careful  to deploy   the  myCommand    bean   as a prototype\n            if that is actually what is needed. If it is a singleton, the same instance of the myCommand bean is\n            returned   each   time.\n\n\n            Alternatively, within the annotation-based component model, you can declare a lookup method\n            through   the  @Lookup   annotation,    as the  following   example     shows:\n\n            Java\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         Command    command    =  createCommand();\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    @Lookup(\"myCommand\")\n                    protected     abstract    Command    createCommand();\n              }\n\n\n\n            Kotlin\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         val   command    =  createCommand()\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    @Lookup(\"myCommand\")\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            Or, more    idiomatically,   you   can  rely on  the  target  bean   getting   resolved   against   the  declared   return\n            type  of the lookup    method:\n\n\n            Java\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         Command    command    =  createCommand();\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    @Lookup\n                    protected     abstract    Command    createCommand();\n              }\n\n            Kotlin\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         val   command    =  createCommand()\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    @Lookup\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            Note that you should typically declare such annotated lookup methods with a concrete stub\n            implementation,      in order   for them    to be  compatible    with   Spring’s  component      scanning    rules  where\n            abstract classes get ignored by default. This limitation does not apply to explicitly registered or\n            explicitly  imported    bean   classes.\n\n\n                              Another way of accessing differently scoped target beans is an ObjectFactory/\n                              Provider   injection  point.  See  Scoped    Beans   as Dependencies.\n                 \n                              You       may        also      find       the       ServiceLocatorFactoryBean             (in      the\n                              org.springframework.beans.factory.config             package)    to be useful.\n\n\n\n            Arbitrary  Method   Replacement\n\n            A less useful form of method injection than lookup method injection is the ability to replace\n            arbitrary   methods     in a  managed     bean    with  another    method     implementation.       You  can   safely  skip\n            the rest  of this section   until you   actually  need   this functionality.\n\n\n            With XML-based configuration metadata, you can use the replaced-method element to replace an\n            existing  method     implementation       with   another,   for  a  deployed    bean.   Consider    the  following    class,\n            which   has  a method    called  computeValue     that  we  want   to override:\n\n\n            Java\n\n\n              public    class   MyValueCalculator        {\n\n\n                    public   String    computeValue(String         input)   {\n                         //  some   real   code...\n                    }\n\n\n                    //  some   other   methods...\n              }\n\n            Kotlin\n\n\n              class    MyValueCalculator       {\n\n\n                    fun  computeValue(input:         String):    String    {\n                         //  some   real   code...\n                    }\n\n\n                    //  some   other   methods...\n              }\n\n\n\n            A class that implements the org.springframework.beans.factory.support.MethodReplacer interface\n            provides   the  new   method    definition,   as the  following   example     shows:\n\n\n            Java\n\n\n              /**\n               *  meant    to  be  used   to  override    the   existing    computeValue(String)\n               *  implementation       in  MyValueCalculator\n               */\n              public    class   ReplacementComputeValue          implements     MethodReplacer       {\n\n\n                    public   Object    reimplement(Object        o,  Method    m,  Object[]    args)    throws   Throwable     {\n                         //  get   the  input    value,   work   with   it,   and  return    a computed     result\n                         String    input   =  (String)    args[0];\n                         ...\n                         return    ...;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              /**\n               *  meant    to  be  used   to  override    the   existing    computeValue(String)\n               *  implementation       in  MyValueCalculator\n               */\n              class    ReplacementComputeValue          : MethodReplacer       {\n\n\n                    override    fun   reimplement(obj:       Any,   method:    Method,    args:   Array<out     Any>):    Any  {\n                         //  get   the  input    value,   work   with   it,   and  return    a computed     result\n                         val   input   =  args[0]    as  String;\n                         ...\n                         return    ...;\n                    }\n              }\n\n\n\n            The  bean   definition    to deploy   the  original   class  and   specify   the  method    override    would    resemble\n            the following    example:\n\n              <bean    id=\"myValueCalculator\"         class=\"x.y.z.MyValueCalculator\">\n                    <!--   arbitrary    method    replacement      -->\n                    <replaced-method       name=\"computeValue\"         replacer=\"replacementComputeValue\">\n                         <arg-type>String</arg-type>\n                    </replaced-method>\n              </bean>\n\n\n              <bean    id=\"replacementComputeValue\"           class=\"a.b.c.ReplacementComputeValue\"/>\n\n\n\n            You  can   use  one   or more    <arg-type/>    elements     within   the  <replaced-method/>       element    to indicate\n            the method signature of the method being overridden. The signature for the arguments is\n            necessary only if the method is overloaded and multiple variants exist within the class. For\n            convenience,     the  type  string  for  an  argument     may   be  a  substring   of  the  fully qualified   type   name.\n            For example,    the  following    all  match  java.lang.String:\n\n\n\n              java.lang.String\n              String\n              Str\n\n\n\n            Because   the  number     of arguments     is often  enough     to distinguish   between     each  possible   choice,   this\n            shortcut can save a lot of typing, by letting you type only the shortest string that matches an\n            argument     type.\n\n            2.1.5.   Bean     Scopes\n\n            When    you   create   a bean   definition,   you   create   a recipe   for  creating   actual   instances    of the  class\n            defined   by  that  bean   definition.   The  idea  that  a bean   definition    is a recipe   is  important,   because   it\n            means   that,  as with   a class, you  can  create   many    object  instances   from   a single  recipe.\n\n\n            You  can  control   not  only  the  various   dependencies      and   configuration     values   that are  to  be plugged\n            into an object that is created from a particular bean definition but also control the scope of the\n            objects  created   from    a particular   bean   definition.   This   approach    is powerful     and  flexible,  because\n            you  can  choose    the scope   of  the objects   you  create   through    configuration    instead   of  having   to bake\n            in the  scope   of  an  object  at  the  Java  class  level.  Beans   can   be  defined   to  be  deployed    in  one  of  a\n            number     of scopes.   The  Spring    Framework      supports    six scopes,   four   of which    are  available   only  if\n            you  use  a web-aware      ApplicationContext.      You  can  also  create  a custom    scope.\n\n            The  following   table  describes    the supported     scopes:\n\n\n            Table 3.

This  single\n            instance   is stored   in a  cache   of such   singleton    beans,   and  all subsequent      requests   and   references\n            for that  named    bean   return   the  cached    object.  The  following    image   shows    how   the  singleton   scope\n            works:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n            Spring’s   concept   of  a singleton    bean   differs  from    the  singleton   pattern   as  defined    in the  Gang    of\n            Four  (GoF)   patterns    book.  The   GoF   singleton   hard-codes     the  scope   of  an  object  such   that  one  and\n\n            only  one  instance   of  a particular   class  is created   per  ClassLoader.     The  scope   of the  Spring   singleton\n            is  best  described  as being   per-container     and   per-bean.   This  means    that,  if  you  define one  bean   for  a\n            particular   class in  a single  Spring   container,   the  Spring   container    creates  one   and  only  one   instance\n            of the  class  defined   by  that  bean   definition.   The   singleton   scope   is the  default   scope   in Spring.   To\n            define  a bean   as  a singleton   in XML,   you   can  define  a bean   as  shown    in the  following   example:\n\n\n\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"/>\n\n\n              <!--   the   following    is   equivalent,     though    redundant    (singleton      scope   is  the  default)\n              -->\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"\n              scope=\"singleton\"/>\n\n\n\n\n            The  Prototype     Scope\n\n            The non-singleton prototype scope of bean deployment results in the creation of a new bean\n            instance every time a request for that specific bean is made. That is, the bean is injected into\n            another    bean   or  you  request    it through    a getBean()    method     call on  the  container.    As  a  rule,  you\n            should   use  the prototype    scope   for all stateful  beans   and   the singleton   scope   for  stateless  beans.\n\n\n            The  following   diagram     illustrates  the Spring   prototype    scope:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n            (A data   access  object   (DAO)   is not  typically   configured    as  a prototype,    because    a  typical  DAO    does\n            not hold   any  conversational     state. It was   easier  for us  to reuse  the  core  of the  singleton   diagram.)\n\n            The  following   example     defines   a bean   as a prototype    in XML:\n\n\n\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"\n              scope=\"prototype\"/>\n\n\n\n            In contrast   to the  other   scopes,  Spring   does   not  manage     the complete     lifecycle  of a prototype    bean.\n\n            The  container    instantiates,   configures,    and  otherwise     assembles    a  prototype    object  and   hands   it to\n            the client,  with   no  further   record   of that  prototype    instance.   Thus,   although    initialization   lifecycle\n            callback   methods    are  called  on  all objects   regardless    of scope,  in  the case  of  prototypes,    configured\n            destruction lifecycle callbacks are not called. The client code must clean up prototype-scoped\n            objects  and   release  expensive     resources    that  the  prototype    beans   hold.  To  get the  Spring   container\n            to release  resources    held  by  prototype-scoped      beans,   try  using  a custom    bean   post-processor,     which\n            holds  a reference    to beans   that  need   to be cleaned    up.\n\n\n            In some   respects,   the  Spring   container’s   role  in  regard   to a prototype-scoped       bean  is a  replacement\n            for the  Java  new  operator.    All lifecycle  management        past  that  point  must    be  handled    by  the  client.\n            (For details  on  the  lifecycle  of a bean   in the  Spring   container,   see  Lifecycle   Callbacks.)\n\n\n            Singleton    Beans   with   Prototype-bean       Dependencies\n\n            When you use singleton-scoped beans with dependencies on prototype beans, be aware that\n            dependencies     are  resolved    at instantiation    time.  Thus,   if  you dependency-inject      a  prototype-scoped\n            bean into a singleton-scoped bean, a new prototype bean is instantiated and then dependency-\n            injected  into  the  singleton   bean.   The  prototype    instance    is  the  sole  instance that  is ever  supplied    to\n            the singleton-scoped      bean.\n\n\n            However,    suppose    you   want   the  singleton-scoped      bean   to acquire   a  new   instance   of the  prototype-\n            scoped bean repeatedly at runtime. You cannot dependency-inject a prototype-scoped bean into\n            your   singleton     bean,    because    that   injection    occurs    only    once,   when     the   Spring    container\n            instantiates the singleton bean and resolves and injects its dependencies. If you need a new\n            instance   of a prototype    bean   at runtime    more   than   once,  see Method     Injection.\n\n\n            Request,    Session,   Application,     and   WebSocket      Scopes\n\n            The  request,   session,   application,    and   websocket   scopes   are   available   only  if you   use  a web-aware\n            Spring ApplicationContext implementation (such as XmlWebApplicationContext). If you use these\n            scopes    with   regular     Spring    IoC   containers,     such   as   the   ClassPathXmlApplicationContext,           an\n            IllegalStateException       that complains     about   an  unknown     bean   scope   is thrown.\n\n\n\n            Initial  Web Configuration\n\n            To support the scoping of beans at the request, session, application, and websocket levels (web-\n            scoped beans), some minor initial configuration is required before you define your beans. (This\n            initial setup  is not  required   for  the standard    scopes:   singleton   and   prototype.)\n\n\n            How   you  accomplish     this  initial setup  depends    on  your   particular   Servlet  environment.\n\n\n            If  you access  scoped    beans   within   Spring   Web    MVC,   in effect,  within   a request   that  is processed    by\n            the  Spring   DispatcherServlet,      no  special   setup   is necessary.   DispatcherServlet       already   exposes    all\n            relevant   state.\n\n\n            If  you use  a  Servlet   web   container,    with  requests    processed    outside   of  Spring’s   DispatcherServlet\n            (for     example,        when        using      JSF      or      Struts),     you       need       to     register      the\n            org.springframework.web.context.request.RequestContextListener ServletRequestListener. This can\n            be done    programmatically       by  using   the WebApplicationInitializer         interface.   Alternatively,    add  the\n            following   declaration    to your   web   application’s   web.xml   file:\n\n              <web-app>\n                    ...\n                    <listener>\n                         <listener-class>\n                               org.springframework.web.context.request.RequestContextListener\n                         </listener-class>\n                    </listener>\n                    ...\n              </web-app>\n\n\n\n            Alternatively,     if   there    are    issues     with    your     listener     setup,    consider      using    Spring’s\n            RequestContextFilter.        The    filter   mapping       depends      on   the    surrounding       web     application\n            configuration,    so you   have   to change    it  as  appropriate.  The  following    listing shows    the  filter part  of\n            a web   application:\n\n\n\n              <web-app>\n                    ...\n                    <filter>\n                         <filter-name>requestContextFilter</filter-name>\n                         <filter-class>org.springframework.web.filter.RequestContextFilter</filter-\n              class>\n                    </filter>\n                    <filter-mapping>\n                         <filter-name>requestContextFilter</filter-name>\n                         <url-pattern>/*</url-pattern>\n                    </filter-mapping>\n                    ...\n              </web-app>\n\n\n\n            DispatcherServlet,     RequestContextListener,        and   RequestContextFilter       all do  exactly   the  same   thing,\n            namely    bind  the  HTTP    request   object  to  the  Thread  that  is servicing   that  request.   This  makes    beans\n            that are  request-   and  session-scoped      available   further  down    the  call chain.\n\n\n\n            Request  scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"loginAction\"       class=\"com.something.LoginAction\"              scope=\"request\"/>\n\n\n\n            The  Spring   container    creates   a new   instance   of  the LoginAction     bean   by using   the  loginAction    bean\n            definition for each and every HTTP request. That is, the loginAction bean is scoped at the HTTP\n            request   level. You  can   change   the  internal   state of  the instance    that is created   as  much   as  you  want,\n            because other instances created from the same loginAction bean definition do not see these\n            changes in state. They are particular to an individual request. When the request completes\n            processing,   the  bean   that is scoped   to  the request   is discarded.\n\n\n            When    using  annotation-driven       components      or Java  configuration,     the  @RequestScope    annotation     can\n\n            be used   to assign  a  component     to the  request   scope.  The   following   example     shows   how   to do  so:\n\n\n            Java\n\n\n              @RequestScope\n              @Component\n              public    class   LoginAction      {\n                    //  ...\n              }\n\n\n\n            Kotlin\n\n\n              @RequestScope\n              @Component\n              class    LoginAction     {\n                    //  ...\n              }\n\n\n\n\n            Session  Scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\"/>\n\n\n\n            The   Spring     container     creates    a  new     instance    of   the   UserPreferences       bean    by   using    the\n            userPreferences bean definition for the lifetime of a single HTTP Session. In other words, the\n            userPreferences     bean   is effectively   scoped   at the  HTTP    Session   level. As  with   request-scoped     beans,\n            you  can  change    the  internal  state  of the  instance   that  is created   as much    as you   want,   knowing    that\n            other  HTTP    Session   instances    that  are  also  using  instances    created   from   the  same    userPreferences\n            bean  definition    do not  see  these  changes    in state,  because   they   are particular    to an  individual   HTTP\n            Session.  When     the  HTTP   Session   is eventually    discarded,    the  bean   that  is scoped   to  that  particular\n            HTTP   Session   is also discarded.\n\n\n            When using annotation-driven components or Java configuration, you can use the @SessionScope\n            annotation    to assign   a component      to the session   scope.\n\n\n            Java\n\n\n              @SessionScope\n              @Component\n              public    class   UserPreferences       {\n                    //  ...\n              }\n\n            Kotlin\n\n\n              @SessionScope\n              @Component\n              class    UserPreferences       {\n                    //  ...\n              }\n\n\n\n\n            Application  Scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"appPreferences\"        class=\"com.something.AppPreferences\"               scope=\"application\"/>\n\n\n\n            The  Spring   container    creates  a  new   instance   of the  AppPreferences     bean   by  using  the  appPreferences\n            bean  definition   once   for the  entire  web   application.    That  is, the appPreferences     bean   is scoped   at the\n            ServletContext     level  and  stored   as a  regular   ServletContext     attribute.  This  is somewhat      similar   to a\n            Spring  singleton    bean  but  differs  in two   important    ways:   It is  a singleton  per ServletContext,     not  per\n            Spring   ApplicationContext      (for  which   there   may   be  several   in any   given  web   application),    and   it  is\n            actually  exposed    and   therefore   visible  as a ServletContext     attribute.\n\n\n            When      using     annotation-driven        components         or   Java     configuration,      you     can    use    the\n            @ApplicationScope annotation to assign a component to the application scope. The following\n            example    shows   how    to do so:\n\n\n            Java\n\n\n              @ApplicationScope\n              @Component\n              public    class   AppPreferences       {\n                    //  ...\n              }\n\n\n\n            Kotlin\n\n\n              @ApplicationScope\n              @Component\n              class    AppPreferences      {\n                    //  ...\n              }\n\n\n\n\n            WebSocket    Scope\n\n            WebSocket     scope   is associated   with   the  lifecycle  of a WebSocket      session  and   applies   to STOMP     over\n            WebSocket     applications,   see  WebSocket     scope   for  more   details.\n\n            Scoped  Beans   as Dependencies\n\n            The  Spring   IoC  container     manages     not  only  the  instantiation    of  your   objects  (beans),   but  also  the\n            wiring   up  of collaborators     (or dependencies).      If  you want   to inject  (for  example)    an  HTTP    request-\n            scoped   bean   into  another    bean   of a  longer-lived    scope,  you   may   choose    to inject  an  AOP   proxy    in\n            place  of  the  scoped   bean.   That   is,  you need   to  inject  a proxy    object  that  exposes    the  same   public\n            interface as the scoped object but that can also retrieve the real target object from the relevant\n            scope  (such   as an  HTTP   request)   and   delegate   method    calls  onto  the  real object.\n\n\n                              You  may   also  use  <aop:scoped-proxy/>       between    beans   that  are  scoped   as  singleton,\n                              with  the  reference    then   going   through    an  intermediate     proxy    that  is serializable\n                              and  therefore   able  to  re-obtain   the target  singleton    bean  on  deserialization.\n\n\n                              When declaring <aop:scoped-proxy/> against a bean of scope prototype, every\n                              method    call on  the  shared    proxy   leads   to the  creation   of a  new   target  instance    to\n                              which   the  call is  then being  forwarded.\n\n                              Also, scoped    proxies   are  not  the only   way   to access  beans    from   shorter   scopes  in  a\n                              lifecycle-safe fashion. You may also declare your injection point (that is, the\n                             constructor    or setter  argument     or  autowired    field)  as ObjectFactory<MyTargetBean>,\n                              allowing   for  a  getObject()    call to  retrieve   the  current   instance    on  demand     every\n                              time  it  is  needed — without    holding    on to  the instance   or  storing  it separately.\n\n\n                              As an extended variant, you may declare ObjectProvider<MyTargetBean> which\n                              delivers    several     additional     access     variants,    including      getIfAvailable      and\n                              getIfUnique.\n\n\n                              The    JSR-330     variant     of   this    is   called    Provider     and     is   used    with     a\n                              Provider<MyTargetBean> declaration and a corresponding get() call for every\n                              retrieval  attempt.   See  here  for  more   details  on  JSR-330   overall.\n\n\n            The  configuration     in  the following    example     is only  one   line, but  it is important    to  understand     the\n            “why”   as well  as  the “how”    behind   it:\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:aop=\"http://www.springframework.org/schema/aop\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\n                         http://www.springframework.org/schema/aop\n                         https://www.springframework.org/schema/aop/spring-aop.xsd\">\n\n\n                    <!--   an  HTTP   Session-scoped      bean   exposed    as  a  proxy   -->\n                    <bean   id=\"userPreferences\"         class=\"com.something.UserPreferences\"               scope=\"session\">\n                         <!--   instructs     the  container     to  proxy    the  surrounding      bean  -->\n                         <aop:scoped-proxy/>         ①\n                    </bean>\n\n\n                    <!--   a singleton-scoped        bean   injected    with   a  proxy   to  the   above   bean   -->\n                    <bean   id=\"userService\"       class=\"com.something.SimpleUserService\">\n                         <!--   a  reference     to  the  proxied    userPreferences       bean   -->\n                         <property     name=\"userPreferences\"          ref=\"userPreferences\"/>\n                    </bean>\n              </beans>\n\n\n            ① The    line that  defines   the proxy.\n\n            To create   such  a proxy,   you  insert  a child  <aop:scoped-proxy/>       element    into  a scoped   bean   definition\n            (see Choosing the Type of Proxy to Create and XML Schema-based configuration). Why do\n            definitions   of beans   scoped   at  the request,   session   and  custom-scope      levels  require   the  <aop:scoped-\n            proxy/> element? Consider the following singleton bean definition and contrast it with what you\n            need to define for the aforementioned scopes (note that the following userPreferences bean\n            definition   as it  stands is incomplete):\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\"/>\n\n\n              <bean    id=\"userManager\"       class=\"com.something.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n            In the  preceding    example,    the  singleton   bean   (userManager)    is injected   with  a  reference   to  the HTTP\n            Session-scoped bean (userPreferences). The salient point here is that the userManager bean is a\n            singleton:   it  is  instantiated exactly   once   per  container,   and   its dependencies      (in this case   only  one,\n            the userPreferences bean) are also injected only once. This means that the userManager bean\n            operates   only  on  the  exact  same   userPreferences      object  (that  is,  the  one  with which   it was  originally\n            injected).\n\n            This  is not  the  behavior    you   want   when    injecting   a  shorter-lived    scoped    bean   into  a longer-lived\n            scoped   bean   (for  example,    injecting   an   HTTP   Session-scoped      collaborating     bean   as  a dependency\n            into singleton    bean).  Rather,   you   need   a single  userManager     object,  and,  for  the lifetime   of an  HTTP\n            Session,  you   need   a userPreferences      object  that  is specific  to the  HTTP    Session.   Thus,  the  container\n\n            creates  an  object   that  exposes   the  exact   same   public   interface   as  the  UserPreferences     class  (ideally\n            an  object  that  is a UserPreferences      instance),   which    can  fetch  the  real  UserPreferences      object  from\n            the scoping mechanism (HTTP request, Session, and so forth). The container injects this proxy\n            object  into the  userManager    bean,   which   is unaware     that  this UserPreferences     reference    is a proxy.   In\n            this  example,     when     a   UserManager     instance     invokes    a   method     on   the   dependency-injected\n            UserPreferences     object,  it is actually   invoking    a  method     on  the  proxy.   The  proxy    then  fetches   the\n            real UserPreferences object from (in this case) the HTTP Session and delegates the method\n            invocation    onto  the  retrieved   real UserPreferences      object.\n\n            Thus, you need the following (correct and complete) configuration when injecting request- and\n            session-scoped     beans   into collaborating     objects,  as the  following   example    shows:\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\">\n                    <aop:scoped-proxy/>\n              </bean>\n\n\n              <bean    id=\"userManager\"       class=\"com.something.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n\n            Choosing    the  Type   of  Proxy   to  Create\n\n            By default, when the Spring container creates a proxy for a bean that is marked up with the\n            <aop:scoped-proxy/>      element,    a CGLIB-based     class  proxy   is created.\n\n\n                              CGLIB   proxies   intercept    only  public   method    calls! Do   not  call non-public    methods\n                             on such   a proxy.   They  are  not  delegated    to the  actual  scoped   target  object.\n\n\n            Alternatively, you can configure the Spring container to create standard JDK interface-based\n            proxies   for such   scoped   beans,   by  specifying   false   for the  value   of the  proxy-target-class      attribute\n            of the  <aop:scoped-proxy/>      element.    Using   JDK  interface-based      proxies   means    that  you  do  not  need\n            additional   libraries   in your   application    classpath    to affect  such   proxying.    However,     it also  means\n            that the  class  of  the  scoped   bean   must    implement     at  least one   interface   and   that  all collaborators\n            into which    the  scoped    bean   is injected   must   reference    the  bean   through    one  of  its interfaces.   The\n            following   example    shows    a proxy   based   on  an  interface:\n\n\n\n              <!--   DefaultUserPreferences          implements     the  UserPreferences       interface     -->\n              <bean    id=\"userPreferences\"        class=\"com.stuff.DefaultUserPreferences\"                 scope=\"session\">\n                    <aop:scoped-proxy        proxy-target-class=\"false\"/>\n              </bean>\n\n\n              <bean    id=\"userManager\"       class=\"com.stuff.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n            For   more    detailed    information      about    choosing     class-based     or  interface-based      proxying,     see\n            Proxying    Mechanisms.\n\n            Custom    Scopes\n\n            The bean scoping mechanism is extensible. You can define your own scopes or even redefine\n            existing  scopes,   although    the  latter is considered     bad  practice   and   you  cannot    override   the  built-in\n            singleton   and   prototype   scopes.\n\n\n\n            Creating  a Custom   Scope\n\n            To   integrate    your    custom     scopes    into   the   Spring    container,     you    need    to   implement      the\n            org.springframework.beans.factory.config.Scope               interface,  which    is  described  in  this section.  For  an\n            idea  of how    to implement     your   own    scopes,  see  the  Scope   implementations       that  are  supplied    with\n            the Spring Framework itself and the Scope javadoc, which explains the methods you need to\n            implement     in more   detail.\n\n\n            The  Scope   interface   has  four  methods     to  get objects   from   the  scope,   remove    them    from   the  scope,\n            and  let them   be  destroyed.\n\n\n            The session scope implementation, for example, returns the session-scoped bean (if it does not\n            exist, the  method    returns   a new   instance   of  the bean,   after  having   bound    it  to  the  session  for  future\n            reference).   The  following    method    returns   the  object  from   the underlying     scope:\n\n\n            Java\n\n\n              Object    get(String     name,   ObjectFactory<?>        objectFactory)\n\n\n\n            Kotlin\n\n\n              fun   get(name:     String,    objectFactory:      ObjectFactory<*>):        Any\n\n\n\n            The session scope implementation, for example, removes the session-scoped bean from the\n            underlying    session.   The   object  should    be  returned,    but  you  can   return   null  if the  object   with  the\n            specified  name    is not  found.  The   following   method     removes    the  object  from   the underlying     scope:\n\n\n            Java\n\n\n              Object    remove(String      name)\n\n\n\n            Kotlin\n\n\n              fun   remove(name:      String):    Any\n\n\n\n            The following method registers a callback that the scope should invoke when it is destroyed or\n            when   the  specified   object  in the  scope   is  destroyed:\n\n\n            Java\n\n\n              void   registerDestructionCallback(String              name,    Runnable    destructionCallback)\n\n            Kotlin\n\n\n              fun   registerDestructionCallback(name:              String,    destructionCallback:        Runnable)\n\n\n\n            See the  javadoc   or  a Spring   scope   implementation      for  more   information     on  destruction    callbacks.\n\n            The  following   method     obtains   the conversation     identifier   for the  underlying    scope:\n\n\n            Java\n\n\n              String    getConversationId()\n\n\n\n            Kotlin\n\n\n              fun   getConversationId():         String\n\n\n\n            This  identifier  is different   for  each   scope.  For  a  session   scoped   implementation,       this identifier   can\n            be the  session   identifier.\n\n\n\n            Using a Custom    Scope\n\n            After  you  write   and   test one  or  more   custom    Scope   implementations,       you  need   to make    the  Spring\n            container   aware    of your   new   scopes.   The  following    method    is the  central   method    to register   a new\n            Scope  with  the  Spring   container:\n\n\n            Java\n\n\n              void   registerScope(String         scopeName,     Scope   scope);\n\n\n\n            Kotlin\n\n\n              fun   registerScope(scopeName:          String,    scope:    Scope)\n\n\n\n            This  method     is declared   on   the  ConfigurableBeanFactory        interface,   which    is available   through    the\n            BeanFactory property on most of the concrete ApplicationContext implementations that ship with\n            Spring.\n\n\n            The  first argument      to the  registerScope(..)       method    is the  unique    name    associated    with   a  scope.\n            Examples of such names in the Spring container itself are singleton and prototype. The second\n            argument      to   the   registerScope(..)        method      is   an   actual    instance     of   the   custom      Scope\n            implementation      that  you  wish   to register  and   use.\n\n            Suppose that you write your custom Scope implementation, and then register it as shown in the\n            next  example.\n\n                              The  next  example     uses  SimpleThreadScope,      which   is included    with  Spring   but  is not\n                             registered by default. The instructions would be the same for your own custom\n                              Scope  implementations.\n\n\n            Java\n\n\n              Scope    threadScope     =  new  SimpleThreadScope();\n              beanFactory.registerScope(\"thread\",               threadScope);\n\n\n\n            Kotlin\n\n\n              val   threadScope     =  SimpleThreadScope()\n              beanFactory.registerScope(\"thread\",               threadScope)\n\n\n\n            You can then create bean definitions that adhere to the scoping rules of your custom Scope, as\n            follows:\n\n\n\n              <bean    id=\"...\"    class=\"...\"     scope=\"thread\">\n\n\n\n            With  a  custom   Scope   implementation,      you  are  not  limited   to programmatic      registration    of the  scope.\n            You  can  also  do  the  Scope  registration   declaratively,    by  using  the  CustomScopeConfigurer       class,  as the\n            following   example    shows:\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:aop=\"http://www.springframework.org/schema/aop\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\n                         http://www.springframework.org/schema/aop\n                         https://www.springframework.org/schema/aop/spring-aop.xsd\">\n\n\n                    <bean   class=\"org.springframework.beans.factory.config.CustomScopeConfigurer\">\n                         <property     name=\"scopes\">\n                               <map>\n                                    <entry    key=\"thread\">\n                                          <bean\n              class=\"org.springframework.context.support.SimpleThreadScope\"/>\n                                    </entry>\n                               </map>\n                         </property>\n                    </bean>\n\n\n                    <bean   id=\"thing2\"      class=\"x.y.Thing2\"        scope=\"thread\">\n                         <property     name=\"name\"      value=\"Rick\"/>\n                         <aop:scoped-proxy/>\n                    </bean>\n\n\n                    <bean   id=\"thing1\"      class=\"x.y.Thing1\">\n                         <property     name=\"thing2\"      ref=\"thing2\"/>\n                    </bean>\n\n\n              </beans>\n\n\n\n\n                              When    you  place   <aop:scoped-proxy/>       within   a <bean>   declaration    for a  FactoryBean\n                             implementation,      it is the factory   bean   itself that  is scoped,   not  the  object  returned\n                              from  getObject().\n\n\n            2.1.6.   Customizing          the   Nature       of  a Bean\n\n            The  Spring   Framework       provides    a number     of  interfaces   you   can  use  to  customize    the  nature   of  a\n            bean.  This  section   groups   them   as follows:\n\n              • Lifecycle   Callbacks\n\n              • ApplicationContextAware        and  BeanNameAware\n\n              • Other   Aware  Interfaces\n\n\n            Lifecycle   Callbacks\n\n            To  interact  with   the  container’s    management       of  the bean    lifecycle,  you  can   implement     the  Spring\n            InitializingBean and DisposableBean interfaces. The container calls afterPropertiesSet() for the\n\n            former   and   destroy()    for the  latter  to let the  bean   perform     certain  actions   upon    initialization  and\n            destruction    of your  beans.\n\n\n                              The  JSR-250   @PostConstruct      and  @PreDestroy     annotations     are  generally   considered\n                              best practice   for receiving    lifecycle  callbacks   in a modern     Spring   application.   Using\n                              these annotations means that your beans are not coupled to Spring-specific\n                             interfaces.  For  details,  see Using   @PostConstruct     and   @PreDestroy.\n\n\n                              If you do not want to use the JSR-250 annotations but you still want to remove\n                              coupling,   consider   init-method    and   destroy-method     bean   definition   metadata.\n\n\n            Internally,  the  Spring   Framework       uses  BeanPostProcessor       implementations       to process   any   callback\n            interfaces it can find and call the appropriate methods. If you need custom features or other\n            lifecycle  behavior    Spring  does   not  by default   offer, you   can  implement     a BeanPostProcessor      yourself.\n            For more    information,    see  Container    Extension    Points.\n\n\n            In addition to the initialization and destruction callbacks, Spring-managed objects may also\n            implement     the  Lifecycle   interface   so  that those   objects  can  participate    in the  startup  and   shutdown\n            process,  as  driven   by the  container’s    own   lifecycle.\n\n\n            The  lifecycle  callback   interfaces   are  described    in this section.\n\n\n\n            Initialization Callbacks\n\n            The     org.springframework.beans.factory.InitializingBean                   interface     lets    a    bean      perform\n            initialization    work    after   the   container     has   set   all  necessary     properties     on   the   bean.    The\n            InitializingBean     interface   specifies   a single  method:\n\n\n\n              void   afterPropertiesSet()         throws    Exception;\n\n\n\n            We  recommend       that  you  do  not  use  the InitializingBean      interface,   because   it unnecessarily     couples\n            the code to Spring. Alternatively, we suggest using the @PostConstruct annotation or specifying a\n            POJO   initialization  method.    In  the  case  of XML-based      configuration    metadata,    you   can  use  the  init-\n            method attribute to specify the name of the method that has a void no-argument signature. With\n            Java  configuration,    you   can  use  the  initMethod    attribute   of @Bean.  See  Receiving    Lifecycle   Callbacks.\n            Consider   the  following    example:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.ExampleBean\"            init-method=\"init\"/>\n\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    public   void   init()    {\n                         //  do   some  initialization       work\n                    }\n              }\n\n            Kotlin\n\n\n              class    ExampleBean     {\n\n\n                    fun  init()    {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            The  preceding    example     has  almost   exactly  the  same   effect  as the  following    example    (which   consists\n            of two  listings):\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.AnotherExampleBean\"/>\n\n\n\n            Java\n\n\n              public    class   AnotherExampleBean        implements     InitializingBean        {\n\n\n                    @Override\n                    public   void   afterPropertiesSet()         {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    AnotherExampleBean        : InitializingBean        {\n\n\n                    override    fun   afterPropertiesSet()         {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            However,    the  first of the  two  preceding    examples     does  not  couple   the  code  to Spring.\n\n\n\n            Destruction   Callbacks\n\n            Implementing the org.springframework.beans.factory.DisposableBean interface lets a bean get a\n            callback   when    the  container    that  contains   it is destroyed.    The   DisposableBean     interface   specifies   a\n            single  method:\n\n\n\n              void   destroy()     throws    Exception;\n\n\n\n            We  recommend       that  you   do  not  use  the DisposableBean      callback   interface,  because    it unnecessarily\n            couples   the  code  to Spring.   Alternatively,    we  suggest   using   the @PreDestroy     annotation    or  specifying\n            a generic   method     that  is supported     by  bean   definitions.   With   XML-based      configuration     metadata,\n            you  can   use  the  destroy-method     attribute   on  the  <bean/>.   With   Java  configuration,     you   can  use  the\n\n            destroyMethod      attribute    of  @Bean.   See    Receiving     Lifecycle    Callbacks.    Consider     the   following\n            definition:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.ExampleBean\"            destroy-method=\"cleanup\"/>\n\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    public   void   cleanup()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     {\n\n\n                    fun  cleanup()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            The  preceding    definition   has  almost   exactly   the same    effect as  the following    definition:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.AnotherExampleBean\"/>\n\n\n\n            Java\n\n\n              public    class   AnotherExampleBean        implements     DisposableBean       {\n\n\n                    @Override\n                    public   void   destroy()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    AnotherExampleBean        : DisposableBean       {\n\n\n                    override    fun   destroy()    {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n            However,    the  first of the  two  preceding    definitions   does   not  couple   the code   to Spring.\n\n\n                              You  can  assign   the destroy-method     attribute   of a <bean>   element    a special  (inferred)\n                              value, which instructs Spring to automatically detect a public close or shutdown\n                              method       on     the    specific     bean      class.     (Any     class     that    implements\n                              java.lang.AutoCloseable or java.io.Closeable would therefore match.) You can\n                             also  set this  special  (inferred)    value   on  the  default-destroy-method        attribute   of  a\n                              <beans> element to apply this behavior to an entire set of beans (see Default\n                              Initialization  and   Destroy   Methods).    Note   that this  is  the  default behavior   with   Java\n                              configuration.\n\n\n\n            Default  Initialization and  Destroy  Methods\n\n            When you write initialization and destroy method callbacks that do not use the Spring-specific\n            InitializingBean      and  DisposableBean      callback   interfaces,   you   typically   write  methods     with   names\n            such as init(), initialize(), dispose(), and so on. Ideally, the names of such lifecycle callback\n            methods    are  standardized      across  a  project  so  that  all developers    use   the same    method    names    and\n            ensure   consistency.\n\n\n            You can configure the Spring container to “look” for named initialization and destroy callback\n            method names on every bean. This means that you, as an application developer, can write your\n            application    classes  and   use  an  initialization   callback   called  init(),   without   having    to configure    an\n            init-method=\"init\"      attribute   with  each   bean   definition.   The  Spring    IoC container    calls  that  method\n            when   the  bean   is created   (and  in accordance     with   the standard    lifecycle  callback   contract   described\n            previously).   This  feature   also enforces    a consistent   naming     convention    for  initialization   and  destroy\n            method    callbacks.\n\n            Suppose that your initialization callback methods are named init() and your destroy callback\n            methods    are  named    destroy().   Your   class then   resembles    the  class  in the following    example:\n\n\n            Java\n\n\n              public    class   DefaultBlogService        implements     BlogService      {\n\n\n                    private    BlogDao    blogDao;\n\n\n                    public   void   setBlogDao(BlogDao        blogDao)     {\n                         this.blogDao      =  blogDao;\n                    }\n\n\n                    //  this   is  (unsurprisingly)       the   initialization      callback     method\n                    public   void   init()    {\n                         if  (this.blogDao       ==  null)   {\n                               throw   new   IllegalStateException(\"The           [blogDao]    property     must   be  set.\");\n                         }\n                    }\n              }\n\n            Kotlin\n\n\n              class    DefaultBlogService        : BlogService      {\n\n\n                    private    var  blogDao:     BlogDao?    =  null\n\n\n                    //  this   is  (unsurprisingly)       the   initialization      callback     method\n                    fun  init()    {\n                         if  (blogDao     ==  null)   {\n                               throw   IllegalStateException(\"The           [blogDao]     property    must   be  set.\")\n                         }\n                    }\n              }\n\n\n\n            You  could  then   use  that class  in a bean   resembling     the  following:\n\n\n\n              <beans    default-init-method=\"init\">\n\n\n                    <bean   id=\"blogService\"       class=\"com.something.DefaultBlogService\">\n                         <property     name=\"blogDao\"       ref=\"blogDao\"      />\n                    </bean>\n\n\n              </beans>\n\n\n\n            The  presence    of the  default-init-method      attribute   on  the  top-level  <beans/>    element   attribute   causes\n            the  Spring   IoC  container    to recognize     a method     called  init  on  the  bean    class  as the  initialization\n            method    callback.   When    a  bean   is  created  and  assembled,     if the bean    class has   such  a  method,    it  is\n            invoked   at the  appropriate     time.\n\n\n            You can configure destroy method callbacks similarly (in XML, that is) by using the default-\n            destroy-method     attribute  on  the  top-level  <beans/>    element.\n\n\n            Where    existing   bean   classes   already   have   callback    methods    that  are   named    at  variance    with  the\n            convention,    you   can  override   the  default   by  specifying   (in  XML,   that  is) the method     name    by using\n            the init-method    and   destroy-method     attributes   of the  <bean/>  itself.\n\n\n            The  Spring   container    guarantees    that  a configured    initialization   callback   is called  immediately     after\n            a bean   is supplied   with   all dependencies.     Thus,   the  initialization  callback    is  called on  the raw   bean\n            reference,   which   means    that  AOP   interceptors    and   so forth  are  not  yet  applied   to the  bean.  A  target\n            bean  is fully  created   first and  then  an  AOP   proxy   (for  example)    with  its interceptor    chain   is  applied.\n            If  the  target bean   and  the  proxy    are  defined   separately,   your   code   can  even   interact   with  the  raw\n            target  bean,   bypassing    the  proxy.   Hence,   it would    be  inconsistent    to  apply   the  interceptors    to the\n            init method, because doing so would couple the lifecycle of the target bean to its proxy or\n            interceptors and leave strange semantics when your code interacts directly with the raw target\n            bean."

    "content": "[[Advisors-Recursive]]\n\n= Recursive Advisors\n\n== What is a Recursive Advisor?\n\nimage:advisors-recursive.png[Advisors Recursive, width=230, float=\"right\", align=\"center\", alt=\"Advisors Recursive\"]\nRecursive advisors are a special type of advisor that can loop through the downstream advisor chain multiple times. \nThis pattern is useful when you need to repeatedly call the LLM until a certain condition is met, such as:\n\n* Executing tool calls in a loop until no more tools need to be called\n* Validating structured output and retrying if validation fails\n* Implementing Evaluation logic with modifications to the request\n* Implementing retry logic with modifications to the request\n\nThe `CallAdvisorChain.copy(CallAdvisor after)` method is the key utility that enables recursive advisor patterns. \nIt creates a new advisor chain that contains only the advisors that come after the specified advisor in the original chain\nand allows the recursive advisor to call this sub-chain as needed.\nThis approach ensures that:\n\n* The recursive advisor can loop through the remaining advisors in the chain\n* Other advisors in the chain can observe and intercept each iteration\n* The advisor chain maintains proper ordering and observability\n* The recursive advisor doesn't re-execute advisors that came before it\n\n== Built-in Recursive Advisors\n\nSpring AI provides two built-in recursive advisors that demonstrate this pattern:\n\n=== ToolCallAdvisor\n\nThe `ToolCallAdvisor` implements the tool calling loop as part of the advisor chain, rather than relying on the model's internal tool execution. This enables other advisors in the chain to intercept and observe the tool calling process.\n\nKey features:\n\n* Disables the model's internal tool execution by setting `setInternalToolExecutionEnabled(false)`\n* Loops through the advisor chain until no more tool calls are present\n* Supports \"return direct\" functionality - when a tool execution has `returnDirect=true`, it interrupts the tool calling loop and returns the tool execution result directly to the client application instead of sending it back to the LLM\n* Uses `callAdvisorChain.copy(this)` to create a sub-chain for recursive calls\n* Includes null safety checks to handle cases where the chat response might be null\n* Supports configurable conversation history management via `conversationHistoryEnabled`\n\nExample usage:\n\n[source,java]\n----\nvar toolCallAdvisor = ToolCallAdvisor.builder()\n    .toolCallingManager(toolCallingManager)\n    .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 300)\n    .build();\n\nvar chatClient = ChatClient.builder(chatModel)\n    .defaultAdvisors(toolCallAdvisor)\n    .build();\n----\n\n==== Conversation History Management\n\nThe `ToolCallAdvisor` includes a `conversationHistoryEnabled` configuration option that controls how conversation history is managed during tool calling iterations.\n\n\nBy default (`conversationHistoryEnabled=true`), the advisor maintains the full conversation history internally during tool call iterations. This means each subsequent LLM call in the tool calling loop includes all previous messages (user message, assistant responses, tool responses).\n\nUse the `.disableInternalConversationHistory()` method to disable internal conversation history management. When disabled, only the last tool response message is passed to the next iteration. This is useful when:\n\n* You have a Chat Memory Advisor registered next in the chain that already manages conversation history\n* You want to reduce token usage by not duplicating history management\n* You're integrating with external conversation memory systems\n\nExample with conversation history disabled:\n\n[source,java]\n----\nvar toolCallAdvisor = ToolCallAdvisor.builder()\n    .toolCallingManager(toolCallingManager)\n    .disableInternalConversationHistory()  // Disable internal history - let ChatMemory handle it\n    .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 300)\n    .build();\n\nvar chatMemoryAdvisor = MessageChatMemoryAdvisor.builder(chatMemory)\n    .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 200)  // Positioned before ToolCallAdvisor\n    .build();\n\nvar chatClient = ChatClient.builder(chatModel)\n    .defaultAdvisors(chatMemoryAdvisor, toolCallAdvisor)\n    .build();\n----\n\n==== Return Direct Functionality\n\nThe \"return direct\" feature allows tools to bypass the LLM and return their results directly to the client application. This is useful when:\n\n* The tool's output is the final answer and doesn't need LLM processing\n* You want to reduce latency by avoiding an additional LLM call\n* The tool result should be returned as-is without interpretation\n\nWhen a tool execution has `returnDirect=true`, the `ToolCallAdvisor` will:\n\n1. Execute the tool call as normal\n2. Detect the `returnDirect` flag in the `ToolExecutionResult`\n3. Break out of the tool calling loop\n4. Return the tool execution result directly to the client application as a `ChatResponse` with the tool's output as the generation content\n\n=== StructuredOutputValidationAdvisor\n\nThe `StructuredOutputValidationAdvisor` validates the structured JSON output against a generated JSON schema and retries the call if validation fails, up to a specified number of attempts.\n\nKey features:\n\n* Automatically generates a JSON schema from the expected output type\n* Validates the LLM response against the schema\n* Retries the call if validation fails, up to a configurable number of attempts\n* Augments the prompt with validation error messages on retry attempts to help the LLM correct its output\n* Uses `callAdvisorChain.copy(this)` to create a sub-chain for recursive calls\n* Optionally supports a custom `JsonMapper` for JSON processing\n\nExample usage:\n\n[source,java]\n----\nvar validationAdvisor = StructuredOutputValidationAdvisor.builder()\n    .outputType(MyResponseType.class)\n    .maxRepeatAttempts(3)\n    .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 1000)\n    .build();\n\nvar chatClient = ChatClient.builder(chatModel)\n    .defaultAdvisors(validationAdvisor)\n    .build();\n----\n"

    "content": "[[Advisors]]\n\n= Advisors API\n\nThe Spring AI Advisors API provides a flexible and powerful way to intercept, modify, and enhance AI-driven interactions in your Spring applications. \nBy leveraging the Advisors API, developers can create more sophisticated, reusable, and maintainable AI components.\n\nThe key benefits include encapsulating recurring Generative AI patterns, transforming data sent to and from Large Language Models (LLMs), and providing portability across various models and use cases.\n\nYou can configure existing advisors using the xref:api/chatclient.adoc#_advisor_configuration_in_chatclient[ChatClient API] as shown in the following example:\n\n[source,java]\n----\n\nChatMemory chatMemory = ... // Initialize your chat memory store\nVectorStore vectorStore = ... // Initialize your vector store\n\nvar chatClient = ChatClient.builder(chatModel)\n    .defaultAdvisors(\n        MessageChatMemoryAdvisor.builder(chatMemory).build(), // chat-memory advisor\n        QuestionAnswerAdvisor.builder(vectorStore).build()    // RAG advisor\n    )\n    .build();\n\nvar conversationId = \"678\";\n\nString response = this.chatClient.prompt()\n    // Set advisor parameters at runtime\t\n    .advisors(advisor -> advisor.param(ChatMemory.CONVERSATION_ID, conversationId))\n    .user(userText)\n    .call()\n\t.content();\n----\n\nIt is recommend to register the advisors at build time using builder's `defaultAdvisors()` method.\n\nAdvisors also participate in the Observability stack, so you can view metrics and traces related to their execution.\n\n- xref:ROOT:api/retrieval-augmented-generation.adoc#_questionansweradvisor[Learn about Question Answer Advisor]\n- xref:ROOT:api/chat-memory.adoc#_memory_in_chat_client[Learn about Chat Memory Advisor]\n\n== Core Components\n\nThe API consists of `CallAdvisor` and `CallAdvisorChain` for non-streaming scenarios, and `StreamAdvisor` and `StreamAdvisorChain` for streaming scenarios. \nIt also includes `ChatClientRequest` to represent the unsealed Prompt request, `ChatClientResponse` for the Chat Completion response. Both hold an `advise-context` to share state across the advisor chain.\n\nimage::advisors-api-classes.jpg[Advisors API Classes, width=600, align=\"center\"]\n\nThe `adviseCall()` and the `adviseStream()` are the key advisor methods, typically performing actions such as examining the unsealed Prompt data, customizing and augmenting the Prompt data, invoking the next entity in the advisor chain, optionally blocking the request, examining the chat completion response, and throwing exceptions to indicate processing errors.\n\nIn addition the `getOrder()` method determines advisor order in the chain, while `getName()` provides a unique advisor name.\n\nThe Advisor Chain, created by the Spring AI framework, allows sequential invocation of multiple advisors ordered by their `getOrder()` values. \nThe lower values are executed first. \nThe last advisor, added automatically, sends the request to the LLM.\n\nFollowing flow diagram illustrates the interaction between the advisor chain and the Chat Model:\n\nimage::advisors-flow.jpg[Advisors API Flow, width=400, align=\"center\"]\n\n. The Spring AI framework creates an `ChatClientRequest` from user's `Prompt` along with an empty advisor `context` object.\n. Each advisor in the chain processes the request, potentially modifying it. Alternatively, it can choose to block the request by not making the call to invoke the next entity. In the latter case, the advisor is responsible for filling out the response.\n. The final advisor, provided by the framework, sends the request to the `Chat Model`.\n. The Chat Model's response is then passed back through the advisor chain and converted into `ChatClientResponse`. Later includes the shared advisor `context` instance.\n. Each advisor can process or modify the response.\n. The final `ChatClientResponse` is returned to the client by extracting the `ChatCompletion`.\n\n=== Advisor Order\nThe execution order of advisors in the chain is determined by the `getOrder()` method. Key points to understand:\n\n* Advisors with lower order values are executed first.\n* The advisor chain operates as a stack:\n** The first advisor in the chain is the first to process the request.\n** It is also the last to process the response.\n* To control execution order:\n** Set the order close to `Ordered.HIGHEST_PRECEDENCE` to ensure an advisor is executed first in the chain (first for request processing, last for response processing).\n** Set the order close to `Ordered.LOWEST_PRECEDENCE` to ensure an advisor is executed last in the chain (last for request processing, first for response processing).\n* Higher values are interpreted as lower priority.\n* If multiple advisors have the same order value, their execution order is not guaranteed.\n\n[NOTE]\n====\nThe seeming contradiction between order and execution sequence is due to the stack-like nature of the advisor chain:\n\n- An advisor with the highest precedence (lowest order value) is added to the top of the stack.\n- It will be the first to process the request as the stack unwinds.\n- It will be the last to process the response as the stack rewinds.\n\n====\n\nAs a reminder, here are the semantics of the Spring `Ordered` interface:\n\n[source,java]\n----\npublic interface Ordered {\n\n    /**\n     * Constant for the highest precedence value.\n     * @see java.lang.Integer#MIN_VALUE\n     */\n    int HIGHEST_PRECEDENCE = Integer.MIN_VALUE;\n\n    /**\n     * Constant for the lowest precedence value.\n     * @see java.lang.Integer#MAX_VALUE\n     */\n    int LOWEST_PRECEDENCE = Integer.MAX_VALUE;\n\n    /**\n     * Get the order value of this object.\n     * <p>Higher values are interpreted as lower priority. As a consequence,\n     * the object with the lowest value has the highest priority (somewhat\n     * analogous to Servlet {@code load-on-startup} values).\n     * <p>Same order values will result in arbitrary sort positions for the\n     * affected objects.\n     * @return the order value\n     * @see #HIGHEST_PRECEDENCE\n     * @see #LOWEST_PRECEDENCE\n     */\n    int getOrder();\n}\n----\n\n\n[TIP]\n====\nFor use cases that need to be first in the chain on both the input and output sides:\n\n1. Use separate advisors for each side.\n2. Configure them with different order values.\n3. Use the advisor context to share state between them.\n====\n\n== API Overview\n\nThe main Advisor interfaces are located in the package `org.springframework.ai.chat.client.advisor.api`. Here are the key interfaces you'll encounter when creating your own advisor:\n\n```java\npublic interface Advisor extends Ordered {\n\n\tString getName();\n\n}\n```\n\nThe two sub-interfaces for synchronous and reactive Advisors are\n\n```java\npublic interface CallAdvisor extends Advisor {\n\n\tChatClientResponse adviseCall(\n\t\tChatClientRequest chatClientRequest, CallAdvisorChain callAdvisorChain);\n\n}\n\n```\n\nand\n\n```java\npublic interface StreamAdvisor extends Advisor {\n\n\tFlux<ChatClientResponse> adviseStream(\n\t\tChatClientRequest chatClientRequest, StreamAdvisorChain streamAdvisorChain);\n\n}\n```\n\nTo continue the chain of Advice, use `CallAdvisorChain` and `StreamAdvisorChain` in your Advice implementation:\n\nThe interfaces are\n\n```java\npublic interface CallAdvisorChain extends AdvisorChain {\n\n\t/**\n\t * Invokes the next {@link CallAdvisor} in the {@link CallAdvisorChain} with the given\n\t * request.\n\t */\n\tChatClientResponse nextCall(ChatClientRequest chatClientRequest);\n\n\t/**\n\t * Returns the list of all the {@link CallAdvisor} instances included in this chain at\n\t * the time of its creation.\n\t */\n\tList<CallAdvisor> getCallAdvisors();\n\n}\n```\n\nand\n\n```java\npublic interface StreamAdvisorChain extends AdvisorChain {\n\n\t/**\n\t * Invokes the next {@link StreamAdvisor} in the {@link StreamAdvisorChain} with the\n\t * given request.\n\t */\n\tFlux<ChatClientResponse> nextStream(ChatClientRequest chatClientRequest);\n\n\t/**\n\t * Returns the list of all the {@link StreamAdvisor} instances included in this chain\n\t * at the time of its creation.\n\t */\n\tList<StreamAdvisor> getStreamAdvisors();\n\n}\n```\n\n== Implementing an Advisor\n\nTo create an advisor, implement either `CallAdvisor` or `StreamAdvisor` (or both). The key method to implement is `nextCall()` for non-streaming or `nextStream()` for streaming advisors.\n\n=== Examples\n\nWe will provide few hands-on examples to illustrate how to implement advisors for observing and augmenting use-cases.\n\n==== Logging Advisor\n\nWe can implement a simple logging advisor that logs the `ChatClientRequest` before and the `ChatClientResponse` after the call to the next advisor in the chain.\nNote that the advisor only observes the request and response and does not modify them.\nThis implementation support both non-streaming and streaming scenarios.\n\n[source,java]\n----\npublic class SimpleLoggerAdvisor implements CallAdvisor, StreamAdvisor {\n\n\tprivate static final Logger logger = LoggerFactory.getLogger(SimpleLoggerAdvisor.class);\n\n\t@Override\n\tpublic String getName() { // <1>\n\t\treturn this.getClass().getSimpleName();\n\t}\n\n\t@Override\n\tpublic int getOrder() { // <2>\n\t\treturn 0; \n\t}\n\n\n\t@Override\n\tpublic ChatClientResponse adviseCall(ChatClientRequest chatClientRequest, CallAdvisorChain callAdvisorChain) {\n\t\tlogRequest(chatClientRequest);\n\n\t\tChatClientResponse chatClientResponse = callAdvisorChain.nextCall(chatClientRequest);\n\n\t\tlogResponse(chatClientResponse);\n\n\t\treturn chatClientResponse;\n\t}\n\n\t@Override\n\tpublic Flux<ChatClientResponse> adviseStream(ChatClientRequest chatClientRequest,\n\t\t\tStreamAdvisorChain streamAdvisorChain) {\n\t\tlogRequest(chatClientRequest);\n\n\t\tFlux<ChatClientResponse> chatClientResponses = streamAdvisorChain.nextStream(chatClientRequest);\n\n\t\treturn new ChatClientMessageAggregator().aggregateChatClientResponse(chatClientResponses, this::logResponse); // <3>\n\t}\n\n\tprivate void logRequest(ChatClientRequest request) {\n\t\tlogger.debug(\"request: {}\", request);\n\t}\n\n\tprivate void logResponse(ChatClientResponse chatClientResponse) {\n\t\tlogger.debug(\"response: {}\", chatClientResponse);\n\t}\n\n}\n----\n<1> Provides a unique name for the advisor.\n<2> You can control the order of execution by setting the order value. Lower values execute first.\n<3> The `MessageAggregator` is a utility class that aggregates the Flux responses into a single ChatClientResponse.\nThis can be useful for logging or other processing that observe the entire response rather than individual items in the stream.\nNote that you can not alter the response in the `MessageAggregator` as it is a read-only operation.\n\n==== Re-Reading (Re2) Advisor\n\nThe \"https://arxiv.org/pdf/2309.06275[Re-Reading Improves Reasoning in Large Language Models]\" article introduces a technique called Re-Reading (Re2) that improves the reasoning capabilities of Large Language Models.\nThe Re2 technique requires augmenting the input prompt like this:\n\n----\n{Input_Query}\nRead the question again: {Input_Query}\n----\n\nImplementing an advisor that applies the Re2 technique to the user's input query can be done like this:\n\n[source,java]\n----\n\npublic class ReReadingAdvisor implements BaseAdvisor {\n\n\tprivate static final String DEFAULT_RE2_ADVISE_TEMPLATE = \"\"\"\n\t\t\t{re2_input_query}\n\t\t\tRead the question again: {re2_input_query}\n\t\t\t\"\"\";\n\n\tprivate final String re2AdviseTemplate;\n\n\tprivate int order = 0;\n\n\tpublic ReReadingAdvisor() {\n\t\tthis(DEFAULT_RE2_ADVISE_TEMPLATE);\n\t}\n\n\tpublic ReReadingAdvisor(String re2AdviseTemplate) {\n\t\tthis.re2AdviseTemplate = re2AdviseTemplate;\n\t}\n\n\t@Override\n\tpublic ChatClientRequest before(ChatClientRequest chatClientRequest, AdvisorChain advisorChain) { // <1>\n\t\tString augmentedUserText = PromptTemplate.builder()\n\t\t\t.template(this.re2AdviseTemplate)\n\t\t\t.variables(Map.of(\"re2_input_query\", chatClientRequest.prompt().getUserMessage().getText()))\n\t\t\t.build()\n\t\t\t.render();\n\n\t\treturn chatClientRequest.mutate()\n\t\t\t.prompt(chatClientRequest.prompt().augmentUserMessage(augmentedUserText))\n\t\t\t.build();\n\t}\n\n\t@Override\n\tpublic ChatClientResponse after(ChatClientResponse chatClientResponse, AdvisorChain advisorChain) {\n\t\treturn chatClientResponse;\n\t}\n\n\t@Override\n\tpublic int getOrder() { // <2>\n\t\treturn this.order;\n\t}\n\n\tpublic ReReadingAdvisor withOrder(int order) {\n\t\tthis.order = order;\n\t\treturn this;\n\t}\n\n}\n----\n<1> The `before` method augments the user's input query applying the Re-Reading technique.\n<2> You can control the order of execution by setting the order value. Lower values execute first.\n\n\n==== Spring AI Built-in Advisors\n\nSpring AI framework provides several built-in advisors to enhance your AI interactions. Here's an overview of the available advisors:\n\n===== Chat Memory Advisors\nThese advisors manage conversation history in a chat memory store:\n\n* `MessageChatMemoryAdvisor`\n+\nRetrieves memory and adds it as a collection of messages to the prompt. This approach maintains the structure of the conversation history.  Note, not all AI Models support this approach.\n\n* `PromptChatMemoryAdvisor`\n+\nRetrieves memory and incorporates it into the prompt's system text.\n\n* `VectorStoreChatMemoryAdvisor`\n+\nRetrieves memory from a VectorStore and adds it into the prompt's system text. This advisor is useful for efficiently searching and retrieving relevant information from large datasets.\n\n===== Question Answering Advisor\n* `QuestionAnswerAdvisor`\n+\nThis advisor uses a vector store to provide question-answering capabilities, implementing the Naive RAG (Retrieval-Augmented Generation) pattern.\n\n* `RetrievalAugmentationAdvisor`\n+\n Advisor that implements common Retrieval Augmented Generation (RAG) flows using the building blocks defined in the `org.springframework.ai.rag` package and following the Modular RAG Architecture.\n\n\n===== Reasoning Advisor\n* `ReReadingAdvisor`\n+\nImplements a re-reading strategy for LLM reasoning, dubbed RE2, to enhance understanding in the input phase. \nBased on the article: [Re-Reading Improves Reasoning in LLMs](https://arxiv.org/pdf/2309.06275).\n\n\n===== Content Safety Advisor\n* `SafeGuardAdvisor`\n+\nA simple advisor designed to prevent the model from generating harmful or inappropriate content.\n\n\n=== Streaming vs Non-Streaming\n\nimage::advisors-non-stream-vs-stream.jpg[Advisors Streaming vs Non-Streaming Flow, width=800, align=\"center\"]\n\n* Non-streaming advisors work with complete requests and responses.\n* Streaming advisors handle requests and responses as continuous streams, using reactive programming concepts (e.g., Flux for responses).\n\n\n// TODO - Add a section on how to implement a streaming advisor with blocking and non-blocking code.\n\n[source,java]\n----\n@Override\npublic Flux<ChatClientResponse> adviseStream(ChatClientRequest chatClientRequest, StreamAdvisorChain chain) {\n    \n    return  Mono.just(chatClientRequest)\n            .publishOn(Schedulers.boundedElastic())\n            .map(request -> {\n                // This can be executed by blocking and non-blocking Threads.\n                // Advisor before next section\n            })\n            .flatMapMany(request -> chain.nextStream(request))\n            .map(response -> {\n                // Advisor after next section\n            });\n}\n----\n\n=== Best Practices\n\n. Keep advisors focused on specific tasks for better modularity.\n. Use the `adviseContext` to share state between advisors when necessary.\n. Implement both streaming and non-streaming versions of your advisor for maximum flexibility.\n. Carefully consider the order of advisors in your chain to ensure proper data flow.\n\n== Breaking API Changes\n\n=== Advisor Interfaces\n\n* In 1.0 M2, there were separate `RequestAdvisor` and `ResponseAdvisor` interfaces.\n** `RequestAdvisor` was invoked before the `ChatModel.call` and `ChatModel.stream` methods.\n** `ResponseAdvisor` was called after these methods.\n* In 1.0 M3, these interfaces have been replaced with:\n** `CallAroundAdvisor`\n** `StreamAroundAdvisor`\n* The `StreamResponseMode`, previously part of `ResponseAdvisor`, has been removed.\n* In 1.0.0 these interfaces have been replaced:\n** `CallAroundAdvisor` -> `CallAdvisor`, `StreamAroundAdvisor` -> `StreamAdvisor`, `CallAroundAdvisorChain` -> `CallAdvisorChain` and `StreamAroundAdvisorChain` -> `StreamAdvisorChain`. \n** `AdvisedRequest` -> `ChatClientRequest` and `AdivsedResponse` -> `ChatClientResponse`.\n\n=== Context Map Handling\n\n* In 1.0 M2:\n** The context map was a separate method argument.\n** The map was mutable and passed along the chain.\n* In 1.0 M3:\n** The context map is now part of the `AdvisedRequest` and `AdvisedResponse` records.\n** The map is immutable.\n** To update the context, use the `updateContext` method, which creates a new unmodifiable map with the updated contents.\n"

    "path": "spring-ai-docs/src/main/antora/modules/ROOT/pages/api/aimetadata.adoc",
    "content": "[[AiMetadata]]\n= AI metadata\n\nUse of an AI, such as OpenAI's ChatGPT, consumes resources and generates metrics returned by the AI provider based on the usage and requests made to the AI through the API.\nConsumption is typically in the form of requests made or tokens used in a given timeframe, such as monthly, that AI providers use to measure this consumption and reset limits.\nYour rate limits are directly determined by your plan when you signed up with your AI provider. For instance, you can review details on OpenAI's https://platform.openai.com/docs/guides/rate-limits?context=tier-free[rate limits] and https://openai.com/pricing#language-models[plans] by following the links.\n\nTo help garner insight into your AI (model) consumption and general usage, Spring AI provides an API to introspect the metadata that is returned by AI providers in their APIs.\n\nSpring AI defines 3 primary interfaces to examine these metrics: `GenerationMetadata`, `RateLimit` and `Usage`. All of these interface can be accessed programmatically from the `ChatResponse` returned and initiated by an AI request.\n\n[[AiMetadata-GenerationMetadata]]\n== `GenerationMetadata` interface\n\nThe `GenerationMetadata` interface is defined as:\n\n.GenerationMetadata interface\n[source,java]\n----\ninterface GenerationMetadata {\n\n\tdefault RateLimit getRateLimit() {\n\t\treturn RateLimit.NULL;\n\t}\n\n\tdefault Usage getUsage() {\n\t\treturn Usage.NULL;\n\t}\n\n}\n----\n\nAn instance of `GenerationMetadata` is automatically created by Spring AI when an AI request is made through the AI provider's API and an AI response is returned. You can get access to the AI provider metadata from the `ChatResponse` using:\n\n.Get access to `GenerationMetadata` from `ChatResponse`\n[source,java]\n----\n@Service\nclass MyService {\n\n\tApplicationObjectType askTheAi(ServiceRequest request) {\n\n        Prompt prompt = createPrompt(request);\n\n        ChatResponse response = chatModel.call(prompt);\n\n        // Process the chat response\n\n        GenerationMetadata metadata = response.getMetadata();\n\n        // Inspect the AI metadata returned in the chat response of the AI providers API\n\n        Long totalTokensUsedInAiPromptAndResponse = metadata.getUsage().getTotalTokens();\n\n        // Act on this information somehow\n\t}\n}\n----\n\nYou might imagine that you can rate limit your own Spring applications using AI, or restrict `Prompt` sizes, which affect your token usage, in an automated, intelligent and realtime manner.\n\nMinimally, you can simply gather these metrics to monitor and report on your consumption.\n\n[[AiMetadata-RateLimit]]\n== RateLimit\n\nThe `RateLimit` interface provides access to actual information returned by an AI provider on your API usage when making AI requests.\n\n.`RateLimit` interface\n[source,java]\n----\ninterface RateLimit {\n\n\tLong getRequestsLimit();\n\n\tLong getRequestsRemaining();\n\n\tDuration getRequestsReset();\n\n\tLong getTokensLimit();\n\n\tLong getTokensRemaining();\n\n\tDuration getTokensReset();\n\n}\n----\n\n`requestsLimit` and `requestsRemaining` let you know how many AI requests, based on the AI provider plan you chose when you signed up, that you can make in total along with your remaining balance within the given timeframe. `requestsReset` returns a `Duration` of time before the timeframe expires and your limits reset based on your chosen plan.\n\nThe methods for `tokensLimit`, `tokensRemaining` and `tokensReset` are similar to the methods for requests, but focus on token limits, balance and resets instead.\n\nThe `RateLimit` instance can be acquired from the `GenerationMetadata`, like so:\n\n.Get access to `RateLimit` from `GenerationMetadata`\n[source,java]\n----\nRateLimit rateLimit = generationMetadata.getRateLimit();\n\nLong tokensRemaining = this.rateLimit.getTokensRemaining();\n\n// do something interesting with the RateLimit metadata\n----\n\nFor AI providers like OpenAI, the rate limit metadata is returned in https://platform.openai.com/docs/guides/rate-limits/rate-limits-in-headers[HTTP headers] from their (REST) API accessible through HTTP clients, like OkHttp.\n\nBecause this can be potentially a costly operation, the collection of rate limit AI metadata must be explicitly enabled. You can enable this collection with a Spring AI property in Spring Boot application.properties; for example:\n\n.Enable API rate limit collection from AI metadata\n[source,properties]\n----\n# Spring Boot application.properties\nspring.ai.openai.metadata.rate-limit-metrics-enabled=true\n----\n\n[[AiMetadata-Usage]]\n== Usage\n\nAs shown <<AiMetadata-GenerationMetadata,above>>, `Usage` data can be obtained from the `GenerationMetadata` object. The `Usage` interface is defined as:\n\n.`Usage` interface\n[source,java]\n----\ninterface Usage {\n\n\tLong getPromptTokens();\n\n\tLong getGenerationTokens();\n\n\tdefault Long getTotalTokens() {\n\t\treturn getPromptTokens() + getGenerationTokens();\n\t}\n\n}\n----\n\nThe method names are self-explanatory, but tells you the tokens that the AI required to process the `Prompt` and generate a response.\n\n`totalTokens` is the sum of `promptTokens` and `generationTokens`. Spring AI computes this by default, but the information is returned in the AI response from OpenAI.\n"

On start-up, the options specified by `spring.ai.elevenlabs.tts` are used, but you can override these at runtime.  The following options are available:\n\n* `modelId`: The ID of the model to use.\n* `voiceId`: The ID of the voice to use.\n* `outputFormat`: The output format of the generated audio.\n* `voiceSettings`:  An object containing voice settings such as `stability`, `similarityBoost`, `style`, `useSpeakerBoost`, and `speed`.\n* `enableLogging`: A boolean to enable or disable logging.\n* `languageCode`: The language code of the input text (e.g., \"en\" for English).\n* `pronunciationDictionaryLocators`:  A list of pronunciation dictionary locators.\n* `seed`: A seed for random number generation, for reproducibility.\n* `previousText`: Text before the main text, for context in multi-turn conversations.\n* `nextText`: Text after the main text, for context in multi-turn conversations.\n* `previousRequestIds`: Request IDs from previous turns in a conversation.\n* `nextRequestIds`: Request IDs for subsequent turns in a conversation.\n* `applyTextNormalization`:  Apply text normalization (\"auto\", \"on\", or \"off\").\n* `applyLanguageTextNormalization`:  Apply language text normalization.\n\nFor example:\n\n[source,java]\n----\nElevenLabsTextToSpeechOptions speechOptions = ElevenLabsTextToSpeechOptions.builder()\n    .model(\"eleven_multilingual_v2\")\n    .voiceId(\"your_voice_id\")\n    .outputFormat(ElevenLabsApi.OutputFormat.MP3_44100_128.getValue())\n    .build();\n\nTextToSpeechPrompt speechPrompt = new TextToSpeechPrompt(\"Hello, this is a text-to-speech example.\", speechOptions);\nTextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt);\n----\n\n=== Using Voice Settings\n\nYou can customize the voice output by providing `VoiceSettings` in the options. This allows you to control properties like stability and similarity.\n\n[source,java]\n----\nvar voiceSettings = new ElevenLabsApi.SpeechRequest.VoiceSettings(0.75f, 0.75f, 0.0f, true);\n\nElevenLabsTextToSpeechOptions speechOptions = ElevenLabsTextToSpeechOptions.builder()\n    .model(\"eleven_multilingual_v2\")\n    .voiceId(\"your_voice_id\")\n    .voiceSettings(voiceSettings)\n    .build();\n\nTextToSpeechPrompt speechPrompt = new TextToSpeechPrompt(\"This is a test with custom voice settings!\", speechOptions);\nTextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt);\n----\n\n== Manual Configuration\n\nAdd the `spring-ai-elevenlabs` dependency to your project's Maven `pom.xml` file:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-elevenlabs</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file:\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-elevenlabs'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNext, create an `ElevenLabsTextToSpeechModel`:\n\n[source,java]\n----\nElevenLabsApi elevenLabsApi = ElevenLabsApi.builder()\n\t\t.apiKey(System.getenv(\"ELEVEN_LABS_API_KEY\"))\n\t\t.build();\n\nElevenLabsTextToSpeechModel elevenLabsTextToSpeechModel = ElevenLabsTextToSpeechModel.builder()\n\t.elevenLabsApi(elevenLabsApi)\n\t.defaultOptions(ElevenLabsTextToSpeechOptions.builder()\n\t\t.model(\"eleven_turbo_v2_5\")\n\t\t.voiceId(\"your_voice_id\") // e.g. \"9BWtsMINqrJLrRacOk9x\"\n\t\t.outputFormat(\"mp3_44100_128\")\n\t\t.build())\n\t.build();\n\n// The call will use the default options configured above.\nTextToSpeechPrompt speechPrompt = new TextToSpeechPrompt(\"Hello, this is a text-to-speech example.\");\nTextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt);\n\nbyte[] responseAsBytes = response.getResult().getOutput();\n----\n\n== Streaming Real-time Audio\n\nThe ElevenLabs Speech API supports real-time audio streaming using chunk transfer encoding.  This allows audio playback to begin before the entire audio file is generated.\n\n[source,java]\n----\nElevenLabsApi elevenLabsApi = ElevenLabsApi.builder()\n\t\t.apiKey(System.getenv(\"ELEVEN_LABS_API_KEY\"))\n\t\t.build();\n\nElevenLabsTextToSpeechModel elevenLabsTextToSpeechModel = ElevenLabsTextToSpeechModel.builder()\n\t.elevenLabsApi(elevenLabsApi)\n\t.build();\n\nElevenLabsTextToSpeechOptions streamingOptions = ElevenLabsTextToSpeechOptions.builder()\n    .model(\"eleven_turbo_v2_5\")\n    .voiceId(\"your_voice_id\")\n    .outputFormat(\"mp3_44100_128\")\n    .build();\n\nTextToSpeechPrompt speechPrompt = new TextToSpeechPrompt(\"Today is a wonderful day to build something people love!\", streamingOptions);\n\nFlux<TextToSpeechResponse> responseStream = elevenLabsTextToSpeechModel.stream(speechPrompt);\n\n// Process the stream, e.g., play the audio chunks\nresponseStream.subscribe(speechResponse -> {\n    byte[] audioChunk = speechResponse.getResult().getOutput();\n    // Play the audioChunk\n});\n\n----\n\n== Voices API\n\nThe ElevenLabs Voices API allows you to retrieve information about available voices, their settings, and default voice settings. You can use this API to discover the `voiceId`s to use in your speech requests.\n\nTo use the Voices API, you'll need to create an instance of `ElevenLabsVoicesApi`:\n\n[source,java]\n----\nElevenLabsVoicesApi voicesApi = ElevenLabsVoicesApi.builder()\n        .apiKey(System.getenv(\"ELEVEN_LABS_API_KEY\"))\n        .build();\n----\n\nYou can then use the following methods:\n\n*   `getVoices()`: Retrieves a list of all available voices.\n*   `getDefaultVoiceSettings()`: Gets the default settings for voices.\n*   `getVoiceSettings(String voiceId)`: Returns the settings for a specific voice.\n*   `getVoice(String voiceId)`: Returns metadata about a specific voice.\n\nExample:\n\n[source,java]\n----\n// Get all voices\nResponseEntity<ElevenLabsVoicesApi.Voices> voicesResponse = voicesApi.getVoices();\nList<ElevenLabsVoicesApi.Voice> voices = voicesResponse.getBody().voices();\n\n// Get default voice settings\nResponseEntity<ElevenLabsVoicesApi.VoiceSettings> defaultSettingsResponse = voicesApi.getDefaultVoiceSettings();\nElevenLabsVoicesApi.VoiceSettings defaultSettings = defaultSettingsResponse.getBody();\n\n// Get settings for a specific voice\nResponseEntity<ElevenLabsVoicesApi.VoiceSettings> voiceSettingsResponse = voicesApi.getVoiceSettings(voiceId);\nElevenLabsVoicesApi.VoiceSettings voiceSettings = voiceSettingsResponse.getBody();\n\n// Get details for a specific voice\nResponseEntity<ElevenLabsVoicesApi.Voice> voiceDetailsResponse = voicesApi.getVoice(voiceId);\nElevenLabsVoicesApi.Voice voiceDetails = voiceDetailsResponse.getBody();\n----\n\n== Example Code\n\n* The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-elevenlabs/src/test/java/org/springframework/ai/elevenlabs/ElevenLabsTextToSpeechModelIT.java[ElevenLabsTextToSpeechModelIT.java] test provides some general examples of how to use the library.\n* The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-elevenlabs/src/test/java/org/springframework/ai/elevenlabs/api/ElevenLabsApiIT.java[ElevenLabsApiIT.java] test provides examples of using the low-level `ElevenLabsApi`."

    "content": "= OpenAI Text-to-Speech (TTS)\n\n== Introduction\n\nThe Audio API provides a speech endpoint based on OpenAI's TTS (text-to-speech) model, enabling users to:\n\n- Narrate a written blog post.\n- Produce spoken audio in multiple languages.\n- Give real-time audio output using streaming.\n\n[NOTE]\n====\nStarting from version `2.0.0-M5`, Spring AI uses the official `openai-java` SDK under the hood for all OpenAI models. The transition is expected to be seamless and there are no breaking changes for existing users of the OpenAI API properties and builders. If you find any issues, please report them to us at https://github.com/spring-projects/spring-ai/issues[Spring AI GitHub Issues].\n====\n\n== Prerequisites\n\n. Create an OpenAI account and obtain an API key. You can sign up at the https://platform.openai.com/signup[OpenAI signup page] and generate an API key on the https://platform.openai.com/account/api-keys[API Keys page].\n. Add the `spring-ai-openai` dependency to your project's build file. For more information, refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section.\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the OpenAI Text-to-Speech Client.\nTo enable it add the following dependency to your project's Maven `pom.xml` file:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file:\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n== Speech Properties\n\n=== Connection Properties\n\nThe prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI.\n\n[cols=\"3,5,1\"]\n|====\n| Property | Description | Default\n| spring.ai.openai.base-url   | The URL to connect to |  https://api.openai.com\n| spring.ai.openai.api-key    | The API Key           |  -\n| spring.ai.openai.organization-id | Optionally you can specify which organization  used for an API request. |  -\n| spring.ai.openai.project-id      | Optionally, you can specify which project is used for an API request. |  -\n|====\n\nTIP: For users that belong to multiple organizations (or are accessing their projects through their legacy user API key), optionally, you can specify which organization and project is used for an API request. \nUsage from these API requests will count as usage for the specified organization and project.\n\n=== Configuration Properties\n\n[NOTE]\n====\nEnabling and disabling of the audio speech auto-configurations are now configured via top level properties with the prefix `spring.ai.model.audio.speech`.\n\nTo enable, spring.ai.model.audio.speech=openai (It is enabled by default)\n\nTo disable, spring.ai.model.audio.speech=none (or any value which doesn't match openai)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix `spring.ai.openai.audio.speech` is used as the property prefix that lets you configure the OpenAI Text-to-Speech client.\n\n[cols=\"3,5,2\"]\n|====\n| Property | Description | Default\n\n| spring.ai.model.audio.speech   | Enable Audio Speech Model |  openai\n| spring.ai.openai.audio.speech.base-url   | The URL to connect to |  https://api.openai.com\n| spring.ai.openai.audio.speech.api-key    | The API Key           |  -\n| spring.ai.openai.audio.speech.organization-id | Optionally you can specify which organization  used for an API request. |  -\n| spring.ai.openai.audio.speech.project-id      | Optionally, you can specify which project is used for an API request. |  -\n| spring.ai.openai.audio.speech.speech-path | The API endpoint path for audio speech generation. Useful for OpenAI-compatible APIs with different endpoint structures. | /v1/audio/speech\n| spring.ai.openai.audio.speech.options.model  | ID of the model to use for generating the audio. Available models: `gpt-4o-mini-tts` (default, optimized for speed and cost), `gpt-4o-tts` (higher quality), `tts-1` (legacy, optimized for speed), or `tts-1-hd` (legacy, optimized for quality). |  gpt-4o-mini-tts\n| spring.ai.openai.audio.speech.options.voice | The voice to use for synthesis. For OpenAI's TTS API, One of the available voices for the chosen model: alloy, echo, fable, onyx, nova, and shimmer. | alloy\n| spring.ai.openai.audio.speech.options.response-format | The format of the audio output. Supported formats are mp3, opus, aac, flac, wav, and pcm. | mp3\n| spring.ai.openai.audio.speech.options.speed | The speed of the voice synthesis. The acceptable range is from 0.25 (slowest) to 4.0 (fastest). | 1.0\n|====\n\nNOTE: You can override the common `spring.ai.openai.base-url`, `spring.ai.openai.api-key`, `spring.ai.openai.organization-id` and `spring.ai.openai.project-id` properties.\nThe `spring.ai.openai.audio.speech.base-url`, `spring.ai.openai.audio.speech.api-key`, `spring.ai.openai.audio.speech.organization-id` and `spring.ai.openai.audio.speech.project-id` properties if set take precedence over the common properties.\nThis is useful if you want to use different OpenAI accounts for different models and different model endpoints.\n\nTIP: All properties prefixed with `spring.ai.openai.audio.speech.options` can be overridden at runtime.\n\n=== Custom API Paths\n\nFor OpenAI-compatible APIs (such as LocalAI, Ollama with OpenAI compatibility, or custom proxies) that use different endpoint paths, you can configure the speech path:\n\n[source,properties]\n----\nspring.ai.openai.audio.speech.speech-path=/custom/path/to/speech\n----\n\nThis is particularly useful when:\n\n* Using API gateways or proxies that modify standard OpenAI paths\n* Working with OpenAI-compatible services that implement different URL structures\n* Testing against mock endpoints with custom paths\n* Deploying in environments with path-based routing requirements\n\n== Runtime Options [[speech-options]]\n\nThe `OpenAiAudioSpeechOptions` class provides the options to use when making a text-to-speech request.\nOn start-up, the options specified by `spring.ai.openai.audio.speech` are used but you can override these at runtime.\n\nThe `OpenAiAudioSpeechOptions` class implements the `TextToSpeechOptions` interface, providing both portable and OpenAI-specific configuration options.\n\nFor example:\n\n[source,java]\n----\nOpenAiAudioSpeechOptions speechOptions = OpenAiAudioSpeechOptions.builder()\n    .model(\"gpt-4o-mini-tts\")\n    .voice(OpenAiAudioApi.SpeechRequest.Voice.ALLOY)\n    .responseFormat(OpenAiAudioApi.SpeechRequest.AudioResponseFormat.MP3)\n    .speed(1.0)\n    .build();\n\nTextToSpeechPrompt speechPrompt = new TextToSpeechPrompt(\"Hello, this is a text-to-speech example.\", speechOptions);\nTextToSpeechResponse response = openAiAudioSpeechModel.call(speechPrompt);\n----\n\n== Manual Configuration\n\nAdd the `spring-ai-openai` dependency to your project's Maven `pom.xml` file:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file:\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNext, create an `OpenAiAudioSpeechModel`:\n\n[source,java]\n----\nvar openAiAudioApi = new OpenAiAudioApi()\n    .apiKey(System.getenv(\"OPENAI_API_KEY\"))\n    .build();\n\nvar openAiAudioSpeechModel = new OpenAiAudioSpeechModel(openAiAudioApi);\n\nvar speechOptions = OpenAiAudioSpeechOptions.builder()\n    .responseFormat(OpenAiAudioApi.SpeechRequest.AudioResponseFormat.MP3)\n    .speed(1.0)\n    .model(OpenAiAudioApi.TtsModel.GPT_4_O_MINI_TTS.value)\n    .build();\n\nvar speechPrompt = new TextToSpeechPrompt(\"Hello, this is a text-to-speech example.\", speechOptions);\nTextToSpeechResponse response = openAiAudioSpeechModel.call(speechPrompt);\n\n// Accessing metadata (rate limit info)\nOpenAiAudioSpeechResponseMetadata metadata = (OpenAiAudioSpeechResponseMetadata) response.getMetadata();\n\nbyte[] responseAsBytes = response.getResult().getOutput();\n----\n\n== Streaming Real-time Audio\n\nThe Speech API provides support for real-time audio streaming using chunk transfer encoding. This means that the audio is able to be played before the full file has been generated and made accessible.\n\nThe `OpenAiAudioSpeechModel` implements the `StreamingTextToSpeechModel` interface, providing both standard and streaming capabilities.\n\n[source,java]\n----\nvar openAiAudioApi = new OpenAiAudioApi()\n    .apiKey(System.getenv(\"OPENAI_API_KEY\"))\n    .build();\n\nvar openAiAudioSpeechModel = new OpenAiAudioSpeechModel(openAiAudioApi);\n\nOpenAiAudioSpeechOptions speechOptions = OpenAiAudioSpeechOptions.builder()\n    .voice(OpenAiAudioApi.SpeechRequest.Voice.ALLOY)\n    .speed(1.0)\n    .responseFormat(OpenAiAudioApi.SpeechRequest.AudioResponseFormat.MP3)\n    .model(OpenAiAudioApi.TtsModel.GPT_4_O_MINI_TTS.value)\n    .build();\n\nTextToSpeechPrompt speechPrompt = new TextToSpeechPrompt(\"Today is a wonderful day to build something people love!\", speechOptions);\n\nFlux<TextToSpeechResponse> responseStream = openAiAudioSpeechModel.stream(speechPrompt);\n\n// You can also stream raw audio bytes directly\nFlux<byte[]> audioByteStream = openAiAudioSpeechModel.stream(\"Hello, world!\");\n----\n\n== Migration Guide\n\nIf you're upgrading from the deprecated `SpeechModel` and `SpeechPrompt` classes, this guide provides detailed instructions for migrating to the new shared interfaces.\n\n=== Breaking Changes Summary\n\nThis migration includes the following breaking changes:\n\n1. **Removed Classes**: Six deprecated classes have been removed from `org.springframework.ai.openai.audio.speech` package\n2. **Package Changes**: Core TTS classes moved to `org.springframework.ai.audio.tts` package\n3. **Type Changes**: The `speed` parameter changed from `Float` to `Double` across all OpenAI TTS components\n4. **Interface Hierarchy**: `TextToSpeechModel` now extends `StreamingTextToSpeechModel`\n\n=== Class Mapping Reference\n\n[cols=\"1,1\"]\n|====\n| Deprecated (Removed) | New Interface\n\n| `SpeechModel`\n| `TextToSpeechModel`\n\n| `StreamingSpeechModel`\n| `StreamingTextToSpeechModel`\n\n| `SpeechPrompt`\n| `TextToSpeechPrompt`\n\n| `SpeechResponse`\n| `TextToSpeechResponse`\n\n| `SpeechMessage`\n| `TextToSpeechMessage`\n\n| `Speech` (in `org.springframework.ai.openai.audio.speech`)\n| `Speech` (in `org.springframework.ai.audio.tts`)\n|====\n\n=== Step-by-Step Migration Instructions\n\n==== Step 1: Update Imports\n\nReplace all imports from the old `org.springframework.ai.openai.audio.speech` package with the new shared interfaces:\n\n[source,text]\n----\nFind:    import org.springframework.ai.openai.audio.speech.SpeechModel;\nReplace: import org.springframework.ai.audio.tts.TextToSpeechModel;\n\nFind:    import org.springframework.ai.openai.audio.speech.StreamingSpeechModel;\nReplace: import org.springframework.ai.audio.tts.StreamingTextToSpeechModel;\n\nFind:    import org.springframework.ai.openai.audio.speech.SpeechPrompt;\nReplace: import org.springframework.ai.audio.tts.TextToSpeechPrompt;\n\nFind:    import org.springframework.ai.openai.audio.speech.SpeechResponse;\nReplace: import org.springframework.ai.audio.tts.TextToSpeechResponse;\n\nFind:    import org.springframework.ai.openai.audio.speech.SpeechMessage;\nReplace: import org.springframework.ai.audio.tts.TextToSpeechMessage;\n\nFind:    import org.springframework.ai.openai.audio.speech.Speech;\nReplace: import org.springframework.ai.audio.tts.Speech;\n----\n\n==== Step 2: Update Type References\n\nReplace all type references in your code:\n\n[source,text]\n----\nFind:    SpeechModel\nReplace: TextToSpeechModel\n\nFind:    StreamingSpeechModel\nReplace: StreamingTextToSpeechModel\n\nFind:    SpeechPrompt\nReplace: TextToSpeechPrompt\n\nFind:    SpeechResponse\nReplace: TextToSpeechResponse\n\nFind:    SpeechMessage\nReplace: TextToSpeechMessage\n----\n\n==== Step 3: Update Speed Parameter (Float → Double)\n\nThe `speed` parameter has changed from `Float` to `Double`. Update all occurrences:\n\n[source,text]\n----\nFind:    .speed(1.0f)\nReplace: .speed(1.0)\n\nFind:    .speed(0.5f)\nReplace: .speed(0.5)\n\nFind:    Float speed\nReplace: Double speed\n----\n\nIf you have serialized data or configuration files with Float values, you'll need to update those as well:\n\n[source,json]\n----\n// Before\n{\n  \"speed\": 1.0\n}\n\n// After (no code change needed for JSON, but be aware of type change in Java)\n{\n  \"speed\": 1.0\n}\n----\n\n==== Step 4: Update Bean Declarations\n\nIf you have Spring Boot auto-configuration or manual bean

    "content": "[[Speech]]\n= Text-To-Speech (TTS) API\n\nSpring AI provides a unified API for Text-To-Speech (TTS) through the `TextToSpeechModel` and `StreamingTextToSpeechModel` interfaces. This allows you to write portable code that works across different TTS providers.\n\n== Supported Providers\n\n- xref:api/audio/speech/openai-speech.adoc[OpenAI's Speech API]\n- xref:api/audio/speech/elevenlabs-speech.adoc[Eleven Labs Text-To-Speech API]\n\n== Common Interface\n\nAll TTS providers implement the following shared interfaces:\n\n=== TextToSpeechModel\n\nThe `TextToSpeechModel` interface provides methods for converting text to speech:\n\n[source,java]\n----\npublic interface TextToSpeechModel extends Model<TextToSpeechPrompt, TextToSpeechResponse>, StreamingTextToSpeechModel {\n\n    /**\n     * Converts text to speech with default options.\n     */\n    default byte[] call(String text) {\n        // Default implementation\n    }\n\n    /**\n     * Converts text to speech with custom options.\n     */\n    TextToSpeechResponse call(TextToSpeechPrompt prompt);\n\n    /**\n     * Returns the default options for this model.\n     */\n    default TextToSpeechOptions getDefaultOptions() {\n        // Default implementation\n    }\n}\n----\n\n=== StreamingTextToSpeechModel\n\nThe `StreamingTextToSpeechModel` interface provides methods for streaming audio in real-time:\n\n[source,java]\n----\n@FunctionalInterface\npublic interface StreamingTextToSpeechModel extends StreamingModel<TextToSpeechPrompt, TextToSpeechResponse> {\n\n    /**\n     * Streams text-to-speech responses with metadata.\n     */\n    Flux<TextToSpeechResponse> stream(TextToSpeechPrompt prompt);\n\n    /**\n     * Streams audio bytes for the given text.\n     */\n    default Flux<byte[]> stream(String text) {\n        // Default implementation\n    }\n}\n----\n\n=== TextToSpeechPrompt\n\nThe `TextToSpeechPrompt` class encapsulates the input text and options:\n\n[source,java]\n----\nTextToSpeechPrompt prompt = new TextToSpeechPrompt(\n    \"Hello, this is a text-to-speech example.\",\n    options\n);\n----\n\n=== TextToSpeechResponse\n\nThe `TextToSpeechResponse` class contains the generated audio and metadata:\n\n[source,java]\n----\nTextToSpeechResponse response = model.call(prompt);\nbyte[] audioBytes = response.getResult().getOutput();\nTextToSpeechResponseMetadata metadata = response.getMetadata();\n----\n\n== Writing Provider-Agnostic Code\n\nOne of the key benefits of the shared TTS interfaces is the ability to write code that works with any TTS provider without modification. The actual provider (OpenAI, ElevenLabs, etc.) is determined by your Spring Boot configuration, allowing you to switch providers without changing application code.\n\n=== Basic Service Example\n\nThe shared interfaces allow you to write code that works with any TTS provider:\n\n[source,java]\n----\n@Service\npublic class NarrationService {\n\n    private final TextToSpeechModel textToSpeechModel;\n\n    public NarrationService(TextToSpeechModel textToSpeechModel) {\n        this.textToSpeechModel = textToSpeechModel;\n    }\n\n    public byte[] narrate(String text) {\n        // Works with any TTS provider\n        return textToSpeechModel.call(text);\n    }\n\n    public byte[] narrateWithOptions(String text, TextToSpeechOptions options) {\n        TextToSpeechPrompt prompt = new TextToSpeechPrompt(text, options);\n        TextToSpeechResponse response = textToSpeechModel.call(prompt);\n        return response.getResult().getOutput();\n    }\n}\n----\n\nThis service works seamlessly with OpenAI, ElevenLabs, or any other TTS provider, with the actual implementation determined by your Spring Boot configuration.\n\n=== Advanced Example: Multi-Provider Support\n\nYou can build applications that support multiple TTS providers simultaneously:\n\n[source,java]\n----\n@Service\npublic class MultiProviderNarrationService {\n\n    private final Map<String, TextToSpeechModel> providers;\n\n    public MultiProviderNarrationService(List<TextToSpeechModel> models) {\n        // Spring will inject all available TextToSpeechModel beans\n        this.providers = models.stream()\n            .collect(Collectors.toMap(\n                model -> model.getClass().getSimpleName(),\n                model -> model\n            ));\n    }\n\n    public byte[] narrateWithProvider(String text, String providerName) {\n        TextToSpeechModel model = providers.get(providerName);\n        if (model == null) {\n            throw new IllegalArgumentException(\"Unknown provider: \" + providerName);\n        }\n        return model.call(text);\n    }\n\n    public Set<String> getAvailableProviders() {\n        return providers.keySet();\n    }\n}\n----\n\n=== Streaming Audio Example\n\nThe shared interfaces also support streaming for real-time audio generation:\n\n[source,java]\n----\n@Service\npublic class StreamingNarrationService {\n\n    private final TextToSpeechModel textToSpeechModel;\n\n    public StreamingNarrationService(TextToSpeechModel textToSpeechModel) {\n        this.textToSpeechModel = textToSpeechModel;\n    }\n\n    public Flux<byte[]> streamNarration(String text) {\n        // TextToSpeechModel extends StreamingTextToSpeechModel\n        return textToSpeechModel.stream(text);\n    }\n\n    public Flux<TextToSpeechResponse> streamWithMetadata(String text, TextToSpeechOptions options) {\n        TextToSpeechPrompt prompt = new TextToSpeechPrompt(text, options);\n        return textToSpeechModel.stream(prompt);\n    }\n}\n----\n\n=== REST Controller Example\n\nBuilding a REST API with provider-agnostic TTS:\n\n[source,java]\n----\n@RestController\n@RequestMapping(\"/api/tts\")\npublic class TextToSpeechController {\n\n    private final TextToSpeechModel textToSpeechModel;\n\n    public TextToSpeechController(TextToSpeechModel textToSpeechModel) {\n        this.textToSpeechModel = textToSpeechModel;\n    }\n\n    @PostMapping(value = \"/synthesize\", produces = \"audio/mpeg\")\n    public ResponseEntity<byte[]> synthesize(@RequestBody SynthesisRequest request) {\n        byte[] audio = textToSpeechModel.call(request.text());\n        return ResponseEntity.ok()\n            .contentType(MediaType.parseMediaType(\"audio/mpeg\"))\n            .header(\"Content-Disposition\", \"attachment; filename=\\\"speech.mp3\\\"\")\n            .body(audio);\n    }\n\n    @GetMapping(value = \"/stream\", produces = MediaType.APPLICATION_OCTET_STREAM_VALUE)\n    public Flux<byte[]> streamSynthesis(@RequestParam String text) {\n        return textToSpeechModel.stream(text);\n    }\n\n    record SynthesisRequest(String text) {}\n}\n----\n\n=== Configuration-Based Provider Selection\n\nSwitch between providers using Spring profiles or properties:\n\n[source,yaml]\n----\n# application-openai.yml\nspring:\n  ai:\n    model:\n      audio:\n        speech: openai\n    openai:\n      api-key: ${OPENAI_API_KEY}\n      audio:\n        speech:\n          options:\n            model: gpt-4o-mini-tts\n            voice: alloy\n\n# application-elevenlabs.yml\nspring:\n  ai:\n    model:\n      audio:\n        speech: elevenlabs\n    elevenlabs:\n      api-key: ${ELEVENLABS_API_KEY}\n      tts:\n        options:\n          model-id: eleven_turbo_v2_5\n          voice-id: your_voice_id\n----\n\nThen activate the desired provider:\n[source,bash]\n----\n# Use OpenAI\njava -jar app.jar --spring.profiles.active=openai\n\n# Use ElevenLabs\njava -jar app.jar --spring.profiles.active=elevenlabs\n----\n\n=== Using Portable Options\n\nFor maximum portability, use only the common `TextToSpeechOptions` interface methods:\n\n[source,java]\n----\n@Service\npublic class PortableNarrationService {\n\n    private final TextToSpeechModel textToSpeechModel;\n\n    public PortableNarrationService(TextToSpeechModel textToSpeechModel) {\n        this.textToSpeechModel = textToSpeechModel;\n    }\n\n    public byte[] createPortableNarration(String text) {\n        // Use provider's default options for maximum portability\n        TextToSpeechOptions defaultOptions = textToSpeechModel.getDefaultOptions();\n        TextToSpeechPrompt prompt = new TextToSpeechPrompt(text, defaultOptions);\n        TextToSpeechResponse response = textToSpeechModel.call(prompt);\n        return response.getResult().getOutput();\n    }\n}\n----\n\n=== Working with Provider-Specific Features\n\nWhen you need provider-specific features, you can still use them while maintaining a portable codebase:\n\n[source,java]\n----\n@Service\npublic class FlexibleNarrationService {\n\n    private final TextToSpeechModel textToSpeechModel;\n\n    public FlexibleNarrationService(TextToSpeechModel textToSpeechModel) {\n        this.textToSpeechModel = textToSpeechModel;\n    }\n\n    public byte[] narrate(String text, TextToSpeechOptions baseOptions) {\n        TextToSpeechOptions options = baseOptions;\n\n        // Apply provider-specific optimizations if available\n        if (textToSpeechModel instanceof OpenAiAudioSpeechModel) {\n            options = OpenAiAudioSpeechOptions.builder()\n                .from(baseOptions)\n                .model(\"gpt-4o-tts\")  // OpenAI-specific: use high-quality model\n                .speed(1.0)\n                .build();\n        } else if (textToSpeechModel instanceof ElevenLabsTextToSpeechModel) {\n            // ElevenLabs-specific options could go here\n        }\n\n        TextToSpeechPrompt prompt = new TextToSpeechPrompt(text, options);\n        TextToSpeechResponse response = textToSpeechModel.call(prompt);\n        return response.getResult().getOutput();\n    }\n}\n----\n\n=== Best Practices for Portable Code\n\n1. **Depend on Interfaces**: Always inject `TextToSpeechModel` rather than concrete implementations\n2. **Use Common Options**: Stick to `TextToSpeechOptions` interface methods for maximum portability\n3. **Handle Metadata Gracefully**: Different providers return different metadata; handle it generically\n4. **Test with Multiple Providers**: Ensure your code works with at least two TTS providers\n5. **Document Provider Assumptions**: If you rely on specific provider behavior, document it clearly\n\n== Provider-Specific Features\n\nWhile the shared interfaces provide portability, each provider also offers specific features through provider-specific options classes (e.g., `OpenAiAudioSpeechOptions`, `ElevenLabsSpeechOptions`). These classes implement the `TextToSpeechOptions` interface while adding provider-specific capabilities."

    "content": "[[Transcription]]\n= Transcription API\n\nSpring AI provides a unified API for Speech-to-Text transcription through the `TranscriptionModel` interface. This allows you to write portable code that works across different transcription providers.\n\n== Supported Providers\n\n- xref:api/audio/transcriptions/openai-transcriptions.adoc[OpenAI's Whisper API]\n- xref:api/audio/transcriptions/azure-openai-transcriptions.adoc[Azure OpenAI Whisper API]\n\n== Common Interface\n\nAll transcription providers implement the following shared interface:\n\n=== TranscriptionModel\n\nThe `TranscriptionModel` interface provides methods for converting audio to text:\n\n[source,java]\n----\npublic interface TranscriptionModel extends Model<AudioTranscriptionPrompt, AudioTranscriptionResponse> {\n\n    /**\n     * Transcribes the audio from the given prompt.\n     */\n    AudioTranscriptionResponse call(AudioTranscriptionPrompt transcriptionPrompt);\n\n    /**\n     * A convenience method for transcribing an audio resource.\n     */\n    default String transcribe(Resource resource) {\n        AudioTranscriptionPrompt prompt = new AudioTranscriptionPrompt(resource);\n        return this.call(prompt).getResult().getOutput();\n    }\n\n    /**\n     * A convenience method for transcribing an audio resource with options.\n     */\n    default String transcribe(Resource resource, AudioTranscriptionOptions options) {\n        AudioTranscriptionPrompt prompt = new AudioTranscriptionPrompt(resource, options);\n        return this.call(prompt).getResult().getOutput();\n    }\n}\n----\n\n=== AudioTranscriptionPrompt\n\nThe `AudioTranscriptionPrompt` class encapsulates the input audio and options:\n\n[source,java]\n----\nResource audioFile = new FileSystemResource(\"/path/to/audio.mp3\");\nAudioTranscriptionPrompt prompt = new AudioTranscriptionPrompt(\n    audioFile,\n    options\n);\n----\n\n=== AudioTranscriptionResponse\n\nThe `AudioTranscriptionResponse` class contains the transcribed text and metadata:\n\n[source,java]\n----\nAudioTranscriptionResponse response = model.call(prompt);\nString transcribedText = response.getResult().getOutput();\nAudioTranscriptionResponseMetadata metadata = response.getMetadata();\n----\n\n== Writing Provider-Agnostic Code\n\nOne of the key benefits of the shared transcription interface is the ability to write code that works with any transcription provider without modification. The actual provider (OpenAI, Azure OpenAI, etc.) is determined by your Spring Boot configuration, allowing you to switch providers without changing application code.\n\n=== Basic Service Example\n\nThe shared interface allows you to write code that works with any transcription provider:\n\n[source,java]\n----\n@Service\npublic class TranscriptionService {\n\n    private final TranscriptionModel transcriptionModel;\n\n    public TranscriptionService(TranscriptionModel transcriptionModel) {\n        this.transcriptionModel = transcriptionModel;\n    }\n\n    public String transcribeAudio(Resource audioFile) {\n        return transcriptionModel.transcribe(audioFile);\n    }\n\n    public String transcribeWithOptions(Resource audioFile, AudioTranscriptionOptions options) {\n        AudioTranscriptionPrompt prompt = new AudioTranscriptionPrompt(audioFile, options);\n        AudioTranscriptionResponse response = transcriptionModel.call(prompt);\n        return response.getResult().getOutput();\n    }\n}\n----\n\nThis service works seamlessly with OpenAI, Azure OpenAI, or any other transcription provider, with the actual implementation determined by your Spring Boot configuration.\n\n== Provider-Specific Features\n\nWhile the shared interface provides portability, each provider also offers specific features through provider-specific options classes (e.g., `OpenAiAudioTranscriptionOptions`, `AzureOpenAiAudioTranscriptionOptions`). These classes implement the `AudioTranscriptionOptions` interface while adding provider-specific capabilities.\n\nFor detailed information about provider-specific features, see the individual provider documentation pages.\n"

When Claude decides to call a tool during streaming:\n\n1. Tool call arguments are accumulated from partial JSON deltas\n2. Tools are executed when the content block completes\n3. Results are sent back to Claude\n4. The conversation continues recursively until Claude provides a final response\n\n[source,java]\n----\nFlux<ChatResponse> stream = chatModel.stream(\n    new Prompt(\"What's the weather in Paris, Tokyo, and New York?\", chatOptions));\n\nString response = stream\n    .collectList()\n    .block()\n    .stream()\n    .map(r -> r.getResult().getOutput().getContent())\n    .filter(Objects::nonNull)\n    .collect(Collectors.joining());\n----\n\n== Streaming\n\nThe Anthropic SDK module supports both synchronous and streaming responses. Streaming allows Claude to return responses incrementally as they're generated.\n\n[source,java]\n----\nFlux<ChatResponse> stream = chatModel.stream(new Prompt(\"Tell me a story\"));\n\nstream.subscribe(response -> {\n    String content = response.getResult().getOutput().getContent();\n    if (content != null) {\n        System.out.print(content);\n    }\n});\n----\n\n== Extended Thinking\n\nAnthropic Claude models support a \"thinking\" feature that allows the model to show its reasoning process before providing a final answer. This is especially useful for complex questions that require step-by-step reasoning, such as math, logic, and analysis tasks.\n\n[NOTE]\n====\n*Supported Models*\n\nThe thinking feature is supported by the following Claude models:\n\n* Claude 4 models (`claude-opus-4-20250514`, `claude-sonnet-4-20250514`)\n* Claude 3.7 Sonnet (`claude-3-7-sonnet-20250219`)\n\n*Model capabilities:*\n\n* *Claude 3.7 Sonnet*: Returns full thinking output.\n* *Claude 4 models*: Support summarized thinking and enhanced tool integration.\n\nAPI request structure is the same across all supported models, but output behavior varies.\n====\n\n=== Thinking Configuration\n\nTo enable thinking, configure the following:\n\n1. **Set a thinking budget**: The `budgetTokens` must be >= 1024 and less than `maxTokens`.\n2. **Set temperature to 1.0**: Required when thinking is enabled.\n\n=== Convenience Builder Methods\n\n`AnthropicChatOptions.Builder` provides convenience methods for thinking configuration:\n\n[source,java]\n----\n// Enable thinking with a specific token budget\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .temperature(1.0)\n    .maxTokens(16000)\n    .thinkingEnabled(10000L)    // budget must be >= 1024 and < maxTokens\n    .build();\n\n// Let Claude adaptively decide whether to think\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .thinkingAdaptive()\n    .build();\n\n// Explicitly disable thinking\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .thinkingDisabled()\n    .build();\n----\n\nYou can also use the raw SDK `ThinkingConfigParam` directly:\n\n[source,java]\n----\nimport com.anthropic.models.messages.ThinkingConfigParam;\nimport com.anthropic.models.messages.ThinkingConfigEnabled;\n\nvar options = AnthropicChatOptions.builder()\n    .thinking(ThinkingConfigParam.ofEnabled(\n        ThinkingConfigEnabled.builder().budgetTokens(10000L).build()))\n    .build();\n----\n\n=== Thinking Display Setting\n\nBy default, full thinking output is returned in the response. You can control this with the `display` parameter to reduce token costs:\n\n* **`SUMMARIZED`** — Claude still thinks fully, but returns a condensed summary instead of the raw chain-of-thought. Reduces output tokens while still providing insight into the reasoning.\n* **`OMITTED`** — Thinking is performed but completely redacted from the response. Only a cryptographic signature is returned (needed for multi-turn continuity). Lowest output token cost.\n\n[source,java]\n----\nimport com.anthropic.models.messages.ThinkingConfigEnabled;\nimport com.anthropic.models.messages.ThinkingConfigAdaptive;\n\n// Enabled thinking with summarized display\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .temperature(1.0)\n    .maxTokens(16000)\n    .thinkingEnabled(10000L, ThinkingConfigEnabled.Display.SUMMARIZED)\n    .build();\n\n// Enabled thinking with omitted display\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .temperature(1.0)\n    .maxTokens(16000)\n    .thinkingEnabled(10000L, ThinkingConfigEnabled.Display.OMITTED)\n    .build();\n\n// Adaptive thinking with summarized display\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .temperature(1.0)\n    .maxTokens(16000)\n    .thinkingAdaptive(ThinkingConfigAdaptive.Display.SUMMARIZED)\n    .build();\n----\n\nNOTE: The display setting does not affect the quality of the final answer — Claude performs the same amount of thinking regardless. It only controls what thinking content is returned in the response.\n\n=== Non-streaming Example\n\n[source,java]\n----\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .temperature(1.0)\n    .maxTokens(16000)\n    .thinkingEnabled(10000L)\n    .build();\n\nChatResponse response = chatModel.call(\n    new Prompt(\"Are there an infinite number of prime numbers such that n mod 4 == 3?\", options));\n\n// The response contains multiple generations:\n// - ThinkingBlock generations (with \"signature\" in metadata)\n// - TextBlock generations (with the final answer)\nfor (Generation generation : response.getResults()) {\n    AssistantMessage message = generation.getOutput();\n    if (message.getMetadata().containsKey(\"signature\")) {\n        // This is a thinking block - contains Claude's reasoning\n        System.out.println(\"Thinking: \" + message.getText());\n        System.out.println(\"Signature: \" + message.getMetadata().get(\"signature\"));\n    }\n    else if (message.getMetadata().containsKey(\"data\")) {\n        // This is a redacted thinking block (safety-redacted reasoning)\n        System.out.println(\"Redacted thinking data: \" + message.getMetadata().get(\"data\"));\n    }\n    else if (message.getText() != null && !message.getText().isBlank()) {\n        // This is the final text response\n        System.out.println(\"Answer: \" + message.getText());\n    }\n}\n----\n\n=== Streaming Example\n\nThinking is fully supported in streaming mode. Thinking deltas and signature deltas are emitted as they arrive:\n\n[source,java]\n----\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .temperature(1.0)\n    .maxTokens(16000)\n    .thinkingEnabled(10000L)\n    .build();\n\nFlux<ChatResponse> stream = chatModel.stream(\n    new Prompt(\"Are there an infinite number of prime numbers such that n mod 4 == 3?\", options));\n\nstream.subscribe(response -> {\n    Generation generation = response.getResult();\n    AssistantMessage message = generation.getOutput();\n\n    if (message.getMetadata().containsKey(\"thinking\")) {\n        // Incremental thinking content\n        System.out.print(message.getText());\n    }\n    else if (message.getMetadata().containsKey(\"signature\")) {\n        // Thinking block signature (emitted at end of thinking)\n        System.out.println(\"\\nSignature: \" + message.getMetadata().get(\"signature\"));\n    }\n    else if (message.getText() != null) {\n        // Final text content\n        System.out.print(message.getText());\n    }\n});\n----\n\n=== Response Structure\n\nWhen thinking is enabled, the response contains different types of content:\n\n[cols=\"2,3,3\", stripes=even]\n|====\n| Content Type | Metadata Key | Description\n\n| **Thinking Block** | `signature` | Claude's reasoning text with a cryptographic signature. In sync mode, the thinking text is in `getText()` and the signature is in `getMetadata().get(\"signature\")`.\n| **Redacted Thinking** | `data` | Safety-redacted reasoning. Contains only a `data` marker, no visible text.\n| **Signature (streaming)** | `signature` | In streaming mode, the signature arrives as a separate delta at the end of a thinking block.\n| **Thinking Delta (streaming)** | `thinking` | Incremental thinking text chunks during streaming. The `thinking` metadata key is set to `true`.\n| **Text Block** | _(none)_ | The final answer text in `getText()`.\n|====\n\n== Multi-Modal Support\n\nThe Anthropic SDK module supports multi-modal inputs, allowing you to send images and PDF documents alongside text in your prompts.\n\n=== Image Input\n\nSend images to Claude for analysis using the `Media` class:\n\n[source,java]\n----\nvar imageResource = new ClassPathResource(\"/test-image.png\");\n\nvar userMessage = UserMessage.builder()\n    .text(\"What do you see in this image?\")\n    .media(List.of(new Media(MimeTypeUtils.IMAGE_PNG, imageResource)))\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(List.of(userMessage)));\n----\n\nSupported image formats: PNG, JPEG, GIF, WebP. Images can be provided as:\n\n* Byte arrays (automatically base64-encoded)\n* HTTPS URLs (passed directly to the API)\n\n=== PDF Document Input\n\nSend PDF documents for Claude to analyze:\n\n[source,java]\n----\nvar pdfResource = new ClassPathResource(\"/document.pdf\");\n\nvar userMessage = UserMessage.builder()\n    .text(\"Please summarize this document.\")\n    .media(List.of(new Media(new MimeType(\"application\", \"pdf\"), pdfResource)))\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(List.of(userMessage)));\n----\n\n=== Multiple Media Items\n\nYou can include multiple images or documents in a single message:\n\n[source,java]\n----\nvar userMessage = UserMessage.builder()\n    .text(\"Compare these two images.\")\n    .media(List.of(\n        new Media(MimeTypeUtils.IMAGE_PNG, image1Resource),\n        new Media(MimeTypeUtils.IMAGE_PNG, image2Resource)))\n    .build();\n----\n\n== Citations\n\nAnthropic's https://docs.anthropic.com/en/docs/build-with-claude/citations[Citations API] allows Claude to reference specific parts of provided documents when generating responses.\nWhen citation documents are included in a prompt, Claude can cite the source material, and citation metadata (character ranges, page numbers, or content blocks) is returned in the response metadata.\n\nCitations help improve:\n\n* **Accuracy verification**: Users can verify Claude's responses against source material\n* **Transparency**: See exactly which parts of documents informed the response\n* **Compliance**: Meet requirements for source attribution in regulated industries\n* **Trust**: Build confidence by showing where information came from\n\n[NOTE]\n====\n*Supported Models*\n\nCitations are supported on Claude 3.7 Sonnet and Claude 4 models (Opus and Sonnet).\n\n*Document Types*\n\nThree types of citation documents are supported:\n\n* **Plain Text**: Text content with character-level citations\n* **PDF**: PDF documents with page-level citations\n* **Custom Content**: User-defined content blocks with block-level citations\n====\n\n=== Creating Citation Documents\n\nUse the `AnthropicCitationDocument` builder to create documents that can be cited:\n\n==== Plain Text Documents\n\n[source,java]\n----\nAnthropicCitationDocument document = AnthropicCitationDocument.builder()\n    .plainText(\"The Eiffel Tower was completed in 1889 in Paris, France. \" +\n               \"It stands 330 meters tall and was designed by Gustave Eiffel.\")\n    .title(\"Eiffel Tower Facts\")\n    .citationsEnabled(true)\n    .build();\n----\n\n==== PDF Documents\n\n[source,java]\n----\n// From file path\nAnthropicCitationDocument document = AnthropicCitationDocument.builder()\n    .pdfFile(\"path/to/document.pdf\")\n    .title(\"Technical Specification\")\n    .citationsEnabled(true)\n    .build();\n\n// From byte array\nbyte[] pdfBytes = loadPdfBytes();\nAnthropicCitationDocument document = AnthropicCitationDocument.builder()\n    .pdf(pdfBytes)\n    .title(\"Product Manual\")\n    .citationsEnabled(true)\n    .build();\n----\n\n==== Custom Content Blocks\n\nFor fine-grained citation control, use custom content blocks:\n\n[source,java]\n----\nAnthropicCitationDocument document = AnthropicCitationDocument.builder()\n    .customContent(\n        \"The Great Wall of China is approximately 21,196 kilometers long.\",\n        \"It was built over many centuries, starting in the 7th century BC.\",\n        \"The wall was constructed to protect Chinese states from invasions.\"\n    )\n    .title(\"Great Wall Facts\")\n    .citationsEnabled(true)\n    .build();\n----\n\n=== Using Citations in Requests\n\nInclude citation documents in your chat options:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"When was the Eiffel Tower built and how tall is it?\",\n        AnthropicChatOptions.builder()\n            .model(\"claude-sonnet-4-20250514\")\n            .maxTokens(1024)\n            .citationDocuments(document)\n            .build()\n    )\n);\n----\n\n==== Multiple Documents\n\nYou can provide multiple documents for Claude to reference:\n\n[source,java]\n----\nAnthropicCitationDocument parisDoc = AnthropicCitationDocument.builder()\n    .plainText(\"Paris is the capital city of France with a population of 2.1 million.\")\n    .title(\"Paris Information\")\n    .citationsEnabled(true)\n    .build();\n\nAnthropicCitationDocument eiffelDoc = AnthropicCitationDocument.builder()\n    .plainText(\"The Eiffel Tower was designed by Gustave Eiffel for the 1889 World's Fair.\")\n    .title(\"Eiffel Tower History\")\n    .citationsEnabled(true)\n    .build();\n\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"What is the capital of France and who designed the Eiffel Tower?\",\n        AnthropicChatOptions.builder()\n            .model(\"claude-sonnet-4-20250514\")\n            .citationDocuments(parisDoc, eiffelDoc)\n            .build()\n    )\n);\n----\n\n=== Accessing Citations\n\nCitations are returned in the response metadata:\n\n[source,java]\n----\nChatResponse response = chatModel.call(prompt);\n\n// Get citations from metadata\n@SuppressWarnings(\"unchecked\")\nList<Citation> citations = (List<Citation>) response.getMetadata().get(\"citations\");\n\n// Optional: Get citation count directly from metadata\nInteger citationCount = (Integer) response.getMetadata().get(\"citationCount\");\nSystem.out.println(\"Total citations: \" + citationCount);\n\n// Process each citation\nfor (Citation citation : citations) {\n    System.out.println(\"Document: \" + citation.getDocumentTitle());\n    System.out.println(\"Location: \" + citation.getLocationDescription());\n    System.out.println(\"Cited text: \" + citation.getCitedText());\n    System.out.println(\"Document index: \" + citation.getDocumentIndex());\n    System.out.println();\n}\n----\n\n=== Citation Types\n\nCitations contain different location information depending on the document type:\n\n==== Character Location (Plain Text)\n\nFor plain text documents, citations include character indices:\n\n[source,java]\n----\nCitation citation = citations.get(0);\nif (citation.getType() == Citation.LocationType.CHAR_LOCATION) {\n    int start = citation.getStartCharIndex();\n    int end = citation.getEndCharIndex();\n    String text = citation.getCitedText();\n    System.out.println(\"Characters \" + start + \"-\" + end + \": \" + text);\n}\n----\n\n==== Page Location (PDF)\n\nFor PDF documents, citations include page numbers:\n\n[source,java]\n----\nCitation citation = citations.get(0);\nif (citation.getType() == Citation.LocationType.PAGE_LOCATION) {\n    int startPage = citation.getStartPageNumber();\n    int endPage = citation.getEndPageNumber();\n    System.out.println(\"Pages \" + startPage + \"-\" + endPage);\n}\n----\n\n==== Content Block Location (Custom Content)\n\nFor custom content, citations reference specific content blocks:\n\n[source,java]\n----\nCitation citation = citations.get(0);\nif (citation.getType() == Citation.LocationType.CONTENT_BLOCK_LOCATION) {\n    int startBlock = citation.getStartBlockIndex();\n    int endBlock = citation.getEndBlockIndex();\n    System.out.println(\"Content blocks \" + startBlock + \"-\" + endBlock);\n}\n----\n\n=== Complete Example\n\nHere's a complete example demonstrating citation usage:\n\n[source,java]\n----\n// Create a citation document\nAnthropicCitationDocument document = AnthropicCitationDocument.builder()\n    .plainText(\"Spring AI is an application framework for AI engineering. \" +\n               \"It provides a Spring-friendly API for developing AI applications. \" +\n               \"The framework includes abstractions for chat models, embedding models, \" +\n               \"and vector databases.\")\n    .title(\"Spring AI Overview\")\n    .citationsEnabled(true)\n    .build();\n\n// Call the model with the document\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"What is Spring AI?\",\n        AnthropicChatOptions.builder()\n            .model(\"claude-sonnet-4-20250514\")\n            .maxTokens(1024)\n            .citationDocuments(document)\n            .build()\n    )\n);\n\n// Display the response\nSystem.out.println(\"Response: \" + response.getResult().getOutput().getText());\nSystem.out.println(\"\\nCitations:\");\n\n// Process citations\nList<Citation> citations = (List<Citation>) response.getMetadata().get(\"citations\");\n\nif (citations != null && !citations.isEmpty()) {\n    for (int i = 0; i < citations.size(); i++) {\n        Citation citation = citations.get(i);\n        System.out.println(\"\\n[\" + (i + 1) + \"] \" + citation.getDocumentTitle());\n        System.out.println(\"    Location: \" + citation.getLocationDescription());\n        System.out.println(\"    Text: \" + citation.getCitedText());\n    }\n} else {\n    System.out.println(\"No citations were provided in the response.\");\n}\n----\n\n=== Best Practices\n\n1. **Use descriptive titles**: Provide meaningful titles for citation documents to help users identify sources in the citations.\n2. **Check for null citations**: Not all responses will include citations, so always validate the citations metadata exists before accessing it.\n3. **Consider document size**: Larger documents provide more context but consume more input tokens and may affect response time.\n4. **Leverage multiple documents**: When answering questions that span multiple sources, provide all relevant documents in a single request rather than making multiple calls.\n5. **Use appropriate document types**: Choose plain text for simple content, PDF for existing documents, and custom content blocks when you need fine-grained control over citation granularity.\n\n=== Citation Document Options\n\n==== Context Field\n\nOptionally provide context about the document that won't be cited but can guide Claude's understanding:\n\n[source,java]\n----\nAnthropicCitationDocument document = AnthropicCitationDocument.builder()\n    .plainText(\"...\")\n    .title(\"Legal Contract\")\n    .context(\"This is a merger agreement dated January 2024 between Company A and Company B\")\n    .build();\n----\n\n==== Controlling Citations\n\nBy default, citations are disabled for all documents (opt-in behavior).\nTo enable citations, explicitly set `citationsEnabled(true)`:\n\n[source,java]\n----\nAnthropicCitationDocument document = AnthropicCitationDocument.builder()\n    .plainText(\"The Eiffel Tower was completed in 1889...\")\n    .title(\"Historical Facts\")\n    .citationsEnabled(true)  // Explicitly enable citations for this document\n    .build();\n----\n\nYou can also provide documents without citations for background context:\n\n[source,java]\n----\nAnthropicCitationDocument backgroundDoc = AnthropicCitationDocument.builder()\n    .plainText(\"Background information about the industry...\")\n    .title(\"Context Document\")\n    // citationsEnabled defaults to false - Claude will use this but not cite it\n    .build();\n----\n\n[NOTE]\n====\nAnthropic requires consistent citation settings across all documents in a request.\nYou cannot mix citation-enabled and citation-disabled documents in the same request.\n====\n\n== Prompt Caching\n\nAnthropic's https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching[Prompt Caching] reduces costs and latency by caching repeated context across API calls. The Anthropic SDK module supports prompt caching with configurable strategies, TTL, and per-message-type settings.\n\n=== Caching Strategies\n\nFive caching strategies are available via `AnthropicCacheStrategy`:\n\n[cols=\"2,5\", stripes=even]\n|====\n| Strategy | Description\n\n| `NONE` | No caching (default). No cache control headers are added.\n| `SYSTEM_ONLY` | Cache system message content. Uses 1 cache breakpoint.\n| `TOOLS_ONLY` | Cache tool definitions only. Uses 1 cache breakpoint.\n| `SYSTEM_AND_TOOLS` | Cache both system messages and tool definitions. Uses 2 cache breakpoints.\n| `CONVERSATION_HISTORY` | Cache system messages, tool definitions, and conversation messages. Uses up to 4 cache breakpoints.\n|====\n\nNOTE: Anthropic allows a maximum of 4 cache breakpoints per request. The implementation tracks breakpoint usage and stops adding cache control once the limit is reached.\n\n=== Basic Usage\n\n[source,java]\n----\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .maxTokens(1024)\n    .cacheOptions(AnthropicCacheOptions.builder()\n        .strategy(AnthropicCacheStrategy.SYSTEM_ONLY)\n        .build())\n    .build();\n\nChatResponse response = chatModel.call(\n    new Prompt(List.of(\n        new SystemMessage(\"You are an expert assistant with deep domain knowledge...\"),\n        new UserMessage(\"What is the capital of France?\")),\n        options));\n----\n\n=== Cache Configuration Options\n\n`AnthropicCacheOptions` provides fine-grained control over caching behavior:\n\n[source,java]\n----\nvar cacheOptions = AnthropicCacheOptions.builder()\n    .strategy(AnthropicCacheStrategy.SYSTEM_AND_TOOLS)\n    .messageTypeTtl(MessageType.SYSTEM, AnthropicCacheTtl.ONE_HOUR)     // 1 hour TTL\n    .messageTypeMinContentLength(MessageType.SYSTEM, 100)                   // Min 100 chars\n    .multiBlockSystemCaching(true)                                          // Per-block caching\n    .build();\n----\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Option | Description | Default\n\n| `strategy` | The caching strategy to use. | `NONE`\n| `messageTypeTtl` | TTL per message type. Available values: `FIVE_MINUTES`, `ONE_HOUR`. | `FIVE_MINUTES` for all types\n| `messageTypeMinContentLength` | Minimum content length required before caching a message type. | `1`\n| `contentLengthFunction` | Custom function to compute content length (e.g., token counting). | `String::length`\n| `multiBlockSystemCaching` | When `true`, each system message becomes a separate cacheable block; cache control is applied to the second-to-last block (static prefix pattern). When `false`, all system messages are joined into one block. | `false`\n|====\n\n=== Multi-Block System Caching\n\nWhen you have both a static system prompt and dynamic instructions, use multi-block system caching to cache only the static portion:\n\n[source,java]\n----\nvar cacheOptions = AnthropicCacheOptions.builder()\n    .strategy(AnthropicCacheStrategy.SYSTEM_ONLY)\n    .multiBlockSystemCaching(true)\n    .build();\n\nChatResponse response = chatModel.call(\n    new Prompt(List.of(\n        new SystemMessage(\"You are an expert knowledge base assistant...\"),  // Static (cached)\n        new SystemMessage(\"Today's date is 2025-02-23. User timezone: PST\"), // Dynamic\n        new UserMessage(\"What are the latest updates?\")),\n        AnthropicChatOptions.builder()\n            .model(\"claude-sonnet-4-20250514\")\n            .cacheOptions(cacheOptions)\n            .build()));\n----\n\n=== Accessing Cache Token Usage\n\nCache token metrics are available through the native SDK `Usage` object:\n\n[source,java]\n----\nChatResponse response = chatModel.call(prompt);\n\ncom.anthropic.models.messages.Usage sdkUsage =\n    (com.anthropic.models.messages.Usage) response.getMetadata().getUsage().getNativeUsage();\nlong cacheCreation = sdkUsage.cacheCreationInputTokens().orElse(0L);\nlong cacheRead = sdkUsage.cacheReadInputTokens().orElse(0L);\n\nSystem.out.println(\"Cache creation tokens: \" + cacheCreation);\nSystem.out.println(\"Cache read tokens: \" + cacheRead);\n----\n\nOn the first request, `cacheCreationInputTokens` will be non-zero (tokens written to cache). On subsequent requests with the same cached prefix, `cacheReadInputTokens` will be non-zero (tokens read from cache at reduced cost).\n\n=== Conversation History Caching\n\nThe `CONVERSATION_HISTORY` strategy caches the entire conversation context, including system messages, tool definitions, and the last user message. This is useful for multi-turn conversations where the growing context would otherwise be re-processed on every request:\n\n[source,java]\n----\nvar cacheOptions = AnthropicCacheOptions.builder()\n    .strategy(AnthropicCacheStrategy.CONVERSATION_HISTORY)\n    .build();\n\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-20250514\")\n    .cacheOptions(cacheOptions)\n    .build();\n\n// First turn\nChatResponse response1 = chatModel.call(\n    new Prompt(List.of(\n        new SystemMessage(\"You are a helpful assistant.\"),\n        new UserMessage(\"What is machine learning?\")),\n        options));\n\n// Second turn - previous context is cached\nChatResponse response2 = chatModel.call(\n    new Prompt(List.of(\n        new SystemMessage(\"You are a helpful assistant.\"),\n        new UserMessage(\"What is machine learning?\"),\n        new AssistantMessage(response1.getResult().getOutput().getText()),\n        new UserMessage(\"Can you give me an example?\")),\n        options));\n----\n\n== Structured Output\n\nStructured output constrains Claude to produce responses conforming to a JSON schema. The Anthropic SDK module also supports Anthropic's effort control for tuning response quality vs speed.\n\n[NOTE]\n====\n*Model Requirement*\n\nStructured output and effort control require `claude-sonnet-4-6` or newer. Older models like `claude-sonnet-4-20250514` do not support these features.\n\n*Schema Requirements*\n\nWhen using JSON schema output, Anthropic requires `\"additionalProperties\": false` for all object types in the schema.\n====\n\n=== JSON Schema Output\n\nConstrain Claude's responses to a specific JSON schema using the `outputSchema` convenience method:\n\n[source,java]\n----\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-6\")\n    .outputSchema(\"\"\"\n        {\n            \"type\": \"object\",\n            \"properties\": {\n                \"name\": {\"type\": \"string\"},\n                \"capital\": {\"type\": \"string\"},\n                \"population\": {\"type\": \"integer\"}\n            },\n            \"required\": [\"name\", \"capital\"],\n            \"additionalProperties\": false\n        }\n        \"\"\")\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"Tell me about France.\", options));\n// Response text will be valid JSON conforming to the schema\n----\n\n=== Effort Control\n\nControl how much compute Claude spends on its response. Lower effort means faster, cheaper responses; higher effort means more thorough reasoning.\n\n[cols=\"2,5\", stripes=even]\n|====\n| Effort Level | Description\n\n| `LOW` | Fast and concise responses with minimal reasoning\n| `MEDIUM` | Balanced trade-off between speed and thoroughness\n| `HIGH` | More thorough reasoning and detailed responses\n| `MAX` | Maximum compute for the most thorough possible responses\n|====\n\n[source,java]\n----\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-6\")\n    .effort(OutputConfig.Effort.LOW)\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"What is the capital of France?\", options));\n----\n\n=== Combined Schema and Effort\n\nYou can combine JSON schema output with effort control:\n\n[source,java]\n----\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-6\")\n    .outputSchema(\"\"\"\n        {\n            \"type\": \"object\",\n            \"properties\": {\n                \"answer\": {\"type\": \"integer\"},\n                \"explanation\": {\"type\": \"string\"}\n            },\n            \"required\": [\"answer\", \"explanation\"],\n            \"additionalProperties\": false\n        }\n        \"\"\")\n    .effort(OutputConfig.Effort.HIGH)\n    .build();\n\nChatResponse response = chatModel.call(\n    new Prompt(\"What is 15 * 23? Show your reasoning.\", options));\n----\n\n=== Direct OutputConfig\n\nFor full control, use the SDK's `OutputConfig` directly:\n\n[source,java]\n----\nimport com.anthropic.models.messages.OutputConfig;\nimport com.anthropic.models.messages.JsonOutputFormat;\nimport com.anthropic.core.JsonValue;\n\nvar outputConfig = OutputConfig.builder()\n    .effort(OutputConfig.Effort.HIGH)\n    .format(JsonOutputFormat.builder()\n        .schema(JsonOutputFormat.Schema.builder()\n            .putAdditionalProperty(\"type\", JsonValue.from(\"object\"))\n            .putAdditionalProperty(\"properties\", JsonValue.from(Map.of(\n                \"name\", Map.of(\"type\", \"string\"))))\n            .putAdditionalProperty(\"additionalProperties\", JsonValue.from(false))\n            .build())\n        .build())\n    .build();\n\nvar options = AnthropicChatOptions.builder()\n    .model(\"claude-sonnet-4-6\")\n    .outputConfig(outputConfig)\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"Tell me about France.\", options));\n----\n\n=== StructuredOutputChatOptions Interface\n\n`AnthropicChatOptions` implements the `StructuredOutputChatOptions` interface, which provides portable `getOutputSchema()` and `setOutputSchema(String)` methods. This allows structured output to work with Spring AI's generic structured output infrastructure.\n\n== Service Tier\n\nAnthropic offers different https://docs.claude.com/en/api/service-tiers[service tiers] that control capacity routing for API requests. You can use `AnthropicServiceTier.AUTO` to opportunistically use priority capacity (lower latency) when available, or `STANDARD_ONLY` to always use standard capacity.\n\nVia Spring Boot properties:\n\n[source,properties]\n----\nspring.ai.anthropic.chat.options.service-tier=auto\n----\n\nOr programmatically per-request:\n\n[source,java]\n----\nvar options = AnthropicChatOptions.builder()\n    .serviceTier(AnthropicServiceTier.AUTO)\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"Hello\", options));\n----\n\n== Per-Request HTTP Headers\n\nThe Anthropic SDK module supports per-request HTTP headers, which are injected into individual API calls. This is distinct from `customHeaders` (which are set at the client level for all requests).\n\nPer-request headers are useful for:\n\n* **Request tracking**: Adding correlation IDs or trace headers per request\n* **Beta API access**: Including beta feature headers for specific requests\n* **Routing**: Adding routing or priority headers for load balancing\n\n[source,java]\n----\nvar options = AnthropicChatOptions.builder()\n    .httpHeaders(Map.of(\n        \"X-Request-Id\", \"req-12345\",\n        \"X-Custom-Tracking\", \"my-tracking-value\"))\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"Hello\", options));\n----\n\nNOTE: `httpHeaders` are per-request and set via `MessageCreateParams.putAdditionalHeader()`. They do not affect other requests. For headers that should apply to all requests, use `customHeaders` instead.\n\n== Sample Controller\n\nHere is an example of a simple `@RestController` class that uses the chat model for text generations:\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final AnthropicChatModel chatModel;\n\n    public ChatController() {\n        var options = AnthropicChatOptions.builder()\n            .model(\"claude-sonnet-4-20250514\")\n            .maxTokens(1024)\n            .apiKey(System.getenv(\"ANTHROPIC_API_KEY\"))\n            .build();\n        this.chatModel = new AnthropicChatModel(options);\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map<String, String> generate(\n            @RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n    public Flux<ChatResponse> generateStream(\n            @RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return chatModel.stream(prompt);\n    }\n}\n----\n\n== Accessing the Raw Response\n\nThe full Anthropic SDK `Message` object is available in the response metadata under the `\"anthropic-response\"` key. This provides access to any fields not explicitly mapped by Spring AI's abstraction:\n\n[source,java]\n----\nChatResponse response = chatModel.call(new Prompt(\"Hello\"));\n\ncom.anthropic.models.messages.Message rawMessage =\n    (com.anthropic.models.messages.Message) response.getMetadata().get(\"anthropic-response\");\n\n// Access native SDK fields\nrawMessage.stopReason();    // Optional<StopReason>\nrawMessage.content();       // List<ContentBlock>\nrawMessage.usage();         // Usage with cache token details\n----\n\nNOTE: The raw response is available for synchronous calls only. Streaming responses do not include it.\n\n== Skills\n\nAnthropic's https://platform.claude.com/docs/en/agents-and-tools/agent-skills/overview[Skills API] extends Claude's capabilities with specialized, pre-packaged abilities for document generation.\nSkills enable Claude to create actual downloadable files -- Excel spreadsheets, PowerPoint presentations, Word documents, and PDFs -- rather than just describing what these documents might contain.\n\n[NOTE]\n====\n*Supported Models*\n\nSkills are supported on Claude Sonnet 4, Claude Sonnet 4.5, Claude Opus 4, and later models.\n\n*Requirements*\n\n* Skills require the code execution capability (automatically enabled by Spring AI when skills are configured)\n* Maximum of 8 skills per request\n* Generated files are available for download via the Files API for 24 hours\n====\n\n=== Pre-built Anthropic Skills\n\nSpring AI provides type-safe access to Anthropic's pre-built skills through the `AnthropicSkill` enum:\n\n[cols=\"2,3,4\", stripes=even]\n|====\n| Skill | Description | Generated File Type\n\n| `XLSX`\n| Excel spreadsheet generation and manipulation\n| `.xlsx` (Microsoft Excel)\n\n| `PPTX`\n| PowerPoint presentation creation\n| `.pptx` (Microsoft PowerPoint)\n\n| `DOCX`\n| Word document generation\n| `.docx` (Microsoft Word)\n\n| `PDF`\n| PDF document creation\n| `.pdf` (Portable Document Format)\n|====\n\n=== Basic Usage\n\nEnable skills by adding them to your `AnthropicChatOptions`:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Create an Excel spreadsheet with Q1 2025 sales data. \" +\n        \"Include columns for Month, Revenue, and Expenses with 3 rows of sample data.\",\n        AnthropicChatOptions.builder()\n            .model(Model.CLAUDE_SONNET_4_5)\n            .maxTokens(4096)\n            .skill(AnthropicSkill.XLSX)\n            .build()\n    )\n);\n\n// Claude will generate an actual Excel file\nString responseText = response.getResult().getOutput().getText();\nSystem.out.println(responseText);\n// Output: \"I've created an Excel spreadsheet with your Q1 2025 sales data...\"\n----\n\n=== Multiple Skills\n\nYou can enable multiple skills in a single request (up to 8):\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Create a sales report with both an Excel file containing the raw data \" +\n        \"and a PowerPoint presentation summarizing the key findings.\",\n        AnthropicChatOptions.builder()\n            .model(Model.CLAUDE_SONNET_4_5)\n            .maxTokens(8192)\n            .skill(AnthropicSkill.XLSX)\n            .skill(AnthropicSkill.PPTX)\n            .build()\n    )\n);\n----\n\n=== Using AnthropicSkillContainer for Advanced Configuration\n\nFor more control over skill types and versions, use `AnthropicSkillContainer` directly:\n\n[source,java]\n----\nAnthropicSkillContainer container = AnthropicSkillContainer.builder()\n    .skill(AnthropicSkill.XLSX)\n    .skill(AnthropicSkill.PPTX, \"20251013\") // Specific version\n    .build();\n\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the quarterly report\",\n        AnthropicChatOptions.builder()\n            .model(Model.CLAUDE_SONNET_4_5)\n            .maxTokens(4096)\n            .skillContainer(container)\n            .build()\n    )\n);\n----\n\n=== Downloading Generated Files\n\nWhen Claude generates files using Skills, the response contains file IDs that can be used to download the actual files via the Files API.\nSpring AI provides the `AnthropicSkillsResponseHelper` utility class for extracting file IDs and downloading files.\n\n==== Extracting File IDs\n\n[source,java]\n----\nimport org.springframework.ai.anthropic.AnthropicSkillsResponseHelper;\n\nChatResponse response = chatModel.call(prompt);\n\n// Extract all file IDs from the response\nList<String> fileIds = AnthropicSkillsResponseHelper.extractFileIds(response);\n\nfor (String fileId : fileIds) {\n    System.out.println(\"Generated file ID: \" + fileId);\n}\n----\n\n==== Downloading All Files\n\nThe `AnthropicSkillsResponseHelper` provides a convenience method to download all generated files at once.\nThis requires the `AnthropicClient` instance (the same one used to create the chat model):\n\n[source,java]\n----\nimport com.anthropic.client.AnthropicClient;\n\n@Autowired\nprivate AnthropicClient anthropicClient;\n\n// Download all files to a target directory\nPath targetDir = Path.of(\"generated-files\");\nFiles.createDirectories(targetDir);\n\nList<Path> savedFiles = AnthropicSkillsResponseHelper.downloadAllFiles(\n        response, anthropicClient, targetDir);\n\nfor (Path file : savedFiles) {\n    System.out.println(\"Downloaded: \" + file.getFileName() +\n                       \" (\" + Files.size(file) + \" bytes)\");\n}\n----\n\n==== Extracting Container ID\n\nFor multi-turn conversations with Skills, you can extract the container ID for reuse:\n\n[source,java]\n----\nString containerId = AnthropicSkillsResponseHelper.extractContainerId(response);\n\nif (containerId != null) {\n    System.out.println(\"Container ID for reuse: \" + containerId);\n}\n----\n\n=== Complete Example\n\nHere's a complete example showing Skills usage with file download:\n\n[source,java]\n----\n@Service\npublic class DocumentGenerationService {\n\n    private final AnthropicChatModel chatModel;\n    private final AnthropicClient anthropicClient;\n\n    public DocumentGenerationService(AnthropicChatModel chatModel,\n                                     AnthropicClient anthropicClient) {\n        this.chatModel = chatModel;\n        this.anthropicClient = anthropicClient;\n    }\n\n    public Path generateSalesReport(String quarter, Path outputDir) throws IOException {\n        // Generate Excel report using Skills\n        ChatResponse response = chatModel.call(\n            new Prompt(\n                \"Create an Excel spreadsheet with \" + quarter + \" sales data. \" +\n                \"Include Month, Revenue, Expenses, and Profit columns.\",\n                AnthropicChatOptions.builder()\n                    .model(Model.CLAUDE_SONNET_4_5)\n                    .maxTokens(4096)\n                    .skill(AnthropicSkill.XLSX)\n                    .build()\n            )\n        );\n\n        // Extract file IDs from the response\n        List<String> fileIds = AnthropicSkillsResponseHelper.extractFileIds(response);\n\n        if (fileIds.isEmpty()) {\n            throw new RuntimeException(\"No file was generated\");\n        }\n\n        // Download all generated files\n        List<Path> savedFiles = AnthropicSkillsResponseHelper.downloadAllFiles(\n                response, anthropicClient, outputDir);\n\n        return savedFiles.get(0);\n    }\n}\n----\n\n=== Best Practices\n\n1. **Use appropriate models**: Skills work best with Claude Sonnet 4 and later models. Ensure you're using a supported model.\n\n2. **Set sufficient max tokens**: Document generation can require significant tokens. Use `maxTokens(4096)` or higher for complex documents.\n\n3. **Be specific in prompts**: Provide clear, detailed instructions about document structure, content, and formatting.\n\n4. **Handle file downloads promptly**: Generated files expire after 24 hours. Download files soon after generation.\n\n5. **Check for file IDs**: Always verify that file IDs were returned before attempting downloads. Some prompts may result in text responses without file generation.\n\n6. **Use defensive error handling**: Wrap file operations in try-catch blocks to handle network issues or expired files gracefully.\n\n[source,java]\n----\nList<String> fileIds = AnthropicSkillsResponseHelper.extractFileIds(response);\n\nif (fileIds.isEmpty()) {\n    // Claude may have responded with text instead of generating a file\n    String text = response.getResult().getOutput().getText();\n    log.warn(\"No files generated. Response: {}\", text);\n    return;\n}\n\ntry {\n    List<Path> files = AnthropicSkillsResponseHelper.downloadAllFiles(\n            response, anthropicClient, targetDir);\n    // Process files...\n} catch (IOException e) {\n    log.error(\"Failed to download file: {}\", e.getMessage());\n}\n----\n\n== Web Search\n\nAnthropic's https://docs.anthropic.com/en/docs/agents-and-tools/tool-use/web-search[Web Search] tool allows Claude to search the web during a conversation and use the results to generate cited responses.\n\n[NOTE]\n====\n* Web search is a built-in server-side tool — no external tool callbacks are needed\n* Web search results automatically include citations with URLs\n* You can combine web search with other tools (function calling, code execution, skills) in the same request\n====\n\n=== Basic Usage\n\nEnable web search by adding an `AnthropicWebSearchTool` to your chat options:\n\n[source,java]\n----\nvar webSearch = AnthropicWebSearchTool.builder().build();\n\nChatResponse response = chatModel.call(\n    new Prompt(\"What is the latest released version of Spring AI?\",\n        AnthropicChatOptions.builder()\n            .webSearchTool(webSearch)\n            .build()));\n\nString answer = response.getResult().getOutput().getText();\n----\n\n=== Configuration Options\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Option | Description | Default\n\n| maxUses | Maximum number of web searches Claude can perform per request | -\n| allowedDomains | Restrict search results to these domains only | -\n| blockedDomains | Exclude these domains from search results | -\n| userLocation | Approximate user location for localizing results (city, country, region, timezone) | -\n|====\n\n=== Domain Filtering\n\nRestrict or exclude specific domains from search results:\n\n[source,java]\n----\nvar webSearch = AnthropicWebSearchTool.builder()\n    .allowedDomains(List.of(\"docs.spring.io\", \"github.com\"))\n    .blockedDomains(List.of(\"example.com\"))\n    .maxUses(5)\n    .build();\n----\n\n=== User Location\n\nProvide approximate location to localize search results:\n\n[source,java]\n----\nvar webSearch = AnthropicWebSearchTool.builder()\n    .userLocation(\"San Francisco\", \"US\", \"California\", \"America/Los_Angeles\")\n    .build();\n----\n\n=== Accessing Web Search Results\n\nWeb search results and citations are available in the response metadata:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\"What happened in tech news today?\",\n        AnthropicChatOptions.builder()\n            .webSearchTool(AnthropicWebSearchTool.builder().build())\n            .build()));\n\n// Get web search results\n@SuppressWarnings(\"unchecked\")\nList<AnthropicWebSearchResult> results =\n    (List<AnthropicWebSearchResult>) response.getMetadata().get(\"web-search-results\");\n\nif (results != null) {\n    for (AnthropicWebSearchResult result : results) {\n        System.out.println(\"Title: \" + result.title());\n        System.out.println(\"URL: \" + result.url());\n        System.out.println(\"Page age: \" + result.pageAge());\n    }\n}\n\n// Get web search citations\n@SuppressWarnings(\"unchecked\")\nList<Citation> citations =\n    (List<Citation>) response.getMetadata().get(\"citations\");\n\nif (citations != null) {\n    for (Citation citation : citations) {\n        if (citation.getType() == Citation.LocationType.WEB_SEARCH_RESULT_LOCATION) {\n            System.out.println(\"Source: \" + citation.getUrl());\n            System.out.println(\"Title: \" + citation.getDocumentTitle());\n            System.out.println(\"Cited text: \" + citation.getCitedText());\n        }\n    }\n}\n----\n\n=== Spring Boot Configuration\n\nConfigure web search via `application.properties` or `application.yml`:\n\n[source,properties]\n----\nspring.ai.anthropic.chat.options.web-search-tool.max-uses=5\nspring.ai.anthropic.chat.options.web-search-tool.allowed-domains=docs.spring.io,github.com\nspring.ai.anthropic.chat.options.web-search-tool.user-location.city=San Francisco\nspring.ai.anthropic.chat.options.web-search-tool.user-location.country=US\n----\n\n== Observability\n\nThe Anthropic SDK implementation supports Spring AI's observability features through Micrometer.\nAll chat model operations are instrumented for monitoring and tracing.\n\n== Logging\n\nEnable SDK logging by setting the environment variable:\n\n[source,bash]\n----\nexport ANTHROPIC_LOG=debug\n----\n\n== Limitations\n\nThe following features are not yet supported:\n\n* Amazon Bedrock backend\n* Google Vertex AI backend\n\nThese features are planned for future releases.\n\n== Additional Resources\n\n* link:https://github.com/anthropics/anthropic-sdk-java[Official Anthropic Java SDK]\n* link:https://docs.anthropic.com/[Anthropic API Documentation]\n* link:https://docs.anthropic.com/en/docs/about-claude/models[Claude Models]\n"

    "content": "= Azure OpenAI Chat\n\nAzure's OpenAI offering, powered by ChatGPT, extends beyond traditional OpenAI capabilities, delivering AI-driven text generation with enhanced functionality. Azure offers additional AI safety and responsible AI features, as highlighted in their recent update https://techcommunity.microsoft.com/t5/ai-azure-ai-services-blog/announcing-new-ai-safety-amp-responsible-ai-features-in-azure/ba-p/3983686[here].\n\nAzure offers Java developers the opportunity to leverage AI's full potential by integrating it with an array of Azure services, which includes AI-related resources such as Vector Stores on Azure.\n\n== Prerequisites\n\nThe Azure OpenAI client offers three options to connect: using an Azure API key or using an OpenAI API Key, or using Microsoft Entra ID.\n\n=== Azure API Key & Endpoint\n\nTo access models using an API key, obtain your Azure OpenAI `endpoint` and `api-key` from the Azure OpenAI Service section on the https://portal.azure.com[Azure Portal].\n\nSpring AI defines two configuration properties:\n\n1. `spring.ai.azure.openai.api-key`: Set this to the value of the `API Key` obtained from Azure.\n2. `spring.ai.azure.openai.endpoint`: Set this to the endpoint URL obtained when provisioning your model in Azure.\n\nYou can set these configuration properties in your `application.properties` or `application.yml` file:\n\n[source,properties]\n----\nspring.ai.azure.openai.api-key=<your-azure-api-key>\nspring.ai.azure.openai.endpoint=<your-azure-endpoint-url>\n----\n\nFor enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference custom environment variables:\n\n[source,yaml]\n----\n# In application.yml\nspring:\n  ai:\n    azure:\n      openai:\n        api-key: ${AZURE_OPENAI_API_KEY}\n        endpoint: ${AZURE_OPENAI_ENDPOINT}\n----\n\n[source,bash]\n----\n# In your environment or .env file\nexport AZURE_OPENAI_API_KEY=<your-azure-openai-api-key>\nexport AZURE_OPENAI_ENDPOINT=<your-azure-openai-endpoint-url>\n----\n\n=== OpenAI Key\n\nTo authenticate with the OpenAI service (not Azure), provide an OpenAI API key. This will automatically set the endpoint to https://api.openai.com/v1.\n\nWhen using this approach, set the `spring.ai.azure.openai.chat.options.deployment-name` property to the name of the https://platform.openai.com/docs/models[OpenAI model] you wish to use.\n\nIn your application configuration:\n\n[source,properties]\n----\nspring.ai.azure.openai.openai-api-key=<your-azure-openai-key>\nspring.ai.azure.openai.chat.options.deployment-name=<openai-model-name>\n----\n\nUsing environment variables with SpEL:\n\n[source,yaml]\n----\n# In application.yml\nspring:\n  ai:\n    azure:\n      openai:\n        openai-api-key: ${AZURE_OPENAI_API_KEY}\n        chat:\n          options:\n            deployment-name: ${AZURE_OPENAI_MODEL_NAME}\n----\n\n[source,bash]\n----\n# In your environment or .env file\nexport AZURE_OPENAI_API_KEY=<your-openai-key>\nexport AZURE_OPENAI_MODEL_NAME=<openai-model-name>\n----\n\n=== Microsoft Entra ID\n\nFor keyless authentication using Microsoft Entra ID (formerly Azure Active Directory), set _only_ the `spring.ai.azure.openai.endpoint` configuration property and _not_ the api-key property mentioned above.\n\nFinding only the endpoint property, your application will evaluate several different options for retrieving credentials and an `OpenAIClient` instance will be created using the token credentials.\n\nNOTE: It is no longer necessary to create a `TokenCredential` bean; it is configured for you automatically.\n\n=== Deployment Name\n\nTo use Azure AI applications, you need to create an Azure AI Deployment through the link:https://oai.azure.com/portal[Azure AI Portal].\nIn Azure, each client must specify a `Deployment Name` to connect to the Azure OpenAI service.\nIt's important to note that the `Deployment Name` is different from the model you choose to deploy.\nFor example, a deployment named 'MyAiDeployment' could be configured to use either the GPT 3.5 Turbo model or the GPT 4.0 model.\n\nTo get started, follow these steps to create a deployment with the default settings:\n\n   Deployment Name: `gpt-4o`\n   Model Name: `gpt-4o`\n\nThis Azure configuration aligns with the default configurations of the Spring Boot Azure AI Starter and its Autoconfiguration feature.\nIf you use a different Deployment Name, make sure to update the configuration property accordingly:\n\n```\nspring.ai.azure.openai.chat.options.deployment-name=<my deployment name>\n```\n\nThe different deployment structures of Azure OpenAI and OpenAI leads to a property in the Azure OpenAI client library named `deploymentOrModelName`.\nThis is because in OpenAI there is no `Deployment Name`, only a `Model Name`.\n\nNOTE: The property `spring.ai.azure.openai.chat.options.model` has been renamed to `spring.ai.azure.openai.chat.options.deployment-name`.\n\nNOTE: If you decide to connect to `OpenAI` instead of `Azure OpenAI`, by setting the `spring.ai.azure.openai.openai-api-key=<Your OpenAI Key>` property,\nthen the `spring.ai.azure.openai.chat.options.deployment-name` is treated as an link:https://platform.openai.com/docs/models[OpenAI model] name.\n\n==== Access the OpenAI Model\n\nYou can configure the client to use directly `OpenAI` instead of the `Azure OpenAI` deployed models.\nFor this you need to set the `spring.ai.azure.openai.openai-api-key=<Your OpenAI Key>` instead of `spring.ai.azure.openai.api-key=<Your Azure OpenAi Key>`.\n\n=== Add Repositories and BOM\n\nSpring AI artifacts are published in Maven Central and Spring Snapshot repositories.\nRefer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system.\n\nTo help with dependency management, Spring AI provides a BOM (bill of materials) to ensure that a consistent version of Spring AI is used throughout the entire project. Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build system.\n\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the Azure OpenAI Chat Client.\nTo enable it add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files:\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-azure-openai</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-azure-openai'\n}\n----\n======\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nThe Azure OpenAI Chat Client is created using the link:https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/openai/azure-ai-openai/src/main/java/com/azure/ai/openai/OpenAIClientBuilder.java[OpenAIClientBuilder] provided by the Azure SDK. Spring AI allows to customize the builder by providing link:https://github.com/spring-projects/spring-ai/blob/main/auto-configurations/models/spring-ai-autoconfigure-model-azure-openai/src/main/java/org/springframework/ai/model/azure/openai/autoconfigure/AzureOpenAIClientBuilderCustomizer.java[AzureOpenAIClientBuilderCustomizer] beans.\n\nA customizer might be used for example to change the default response timeout:\n\n[source,java]\n----\n@Configuration\npublic class AzureOpenAiConfig {\n\n\t@Bean\n\tpublic AzureOpenAIClientBuilderCustomizer responseTimeoutCustomizer() {\n\t\treturn openAiClientBuilder -> {\n\t\t\tHttpClientOptions clientOptions = new HttpClientOptions()\n\t\t\t\t\t.setResponseTimeout(Duration.ofMinutes(5));\n\t\t\topenAiClientBuilder.httpClient(HttpClient.createDefault(clientOptions));\n\t\t};\n\t}\n\n}\n----\n\n\n\n=== Chat Properties\n\nThe prefix `spring.ai.azure.openai` is the property prefix to configure the connection to Azure OpenAI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.azure.openai.api-key |  The Key from Azure AI OpenAI `Keys and Endpoint` section under `Resource Management`  | -\n| spring.ai.azure.openai.endpoint | The endpoint from the Azure AI OpenAI `Keys and Endpoint` section under `Resource Management` | -\n| spring.ai.azure.openai.openai-api-key |  (non Azure) OpenAI API key. Used to authenticate with the OpenAI service, instead of Azure OpenAI.\nThis automatically sets the endpoint to https://api.openai.com/v1. Use either `api-key` or `openai-api-key` property.\nWith this configuration the `spring.ai.azure.openai.chat.options.deployment-name` is treated as an https://platform.openai.com/docs/models[OpenAi Model] name.| -\n| spring.ai.azure.openai.custom-headers | A map of custom headers to be included in the API requests. Each entry in the map represents a header, where the key is the header name and the value is the header value. | Empty map\n|====\n\n[NOTE]\n====\nEnabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`.\n\nTo enable, spring.ai.model.chat=azure-openai (It is enabled by default)\n\nTo disable, spring.ai.model.chat=none (or any value which doesn't match azure-openai)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix `spring.ai.azure.openai.chat` is the property prefix that configures the `ChatModel` implementation for Azure OpenAI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.azure.openai.chat.enabled (Removed and no longer valid) | Enable Azure OpenAI chat model.  | true\n| spring.ai.model.chat | Enable Azure OpenAI chat model.  | azure-openai\n| spring.ai.azure.openai.chat.options.deployment-name | In use with Azure, this refers to the \"Deployment Name\" of your model, which you can find at https://oai.azure.com/portal.\nIt's important to note that within an Azure OpenAI deployment, the \"Deployment Name\" is distinct from the model itself.\nThe confusion around these terms stems from the intention to make the Azure OpenAI client library compatible with the original OpenAI endpoint.\nThe deployment structures offered by Azure OpenAI and Sam Altman's OpenAI differ significantly.\nDeployments model name to provide as part of this completions request. | gpt-4o\n| spring.ai.azure.openai.chat.options.maxTokens | The maximum number of tokens to generate in the chat completion. The total length of input tokens and generated tokens is limited by the model's context length. *Use for non-reasoning models (e.g., gpt-4o, gpt-3.5-turbo). Cannot be used with maxCompletionTokens.* | -\n| spring.ai.azure.openai.chat.options.maxCompletionTokens | An upper bound for the number of tokens that can be generated for a completion, including visible output tokens and reasoning tokens. *Required for reasoning models (e.g., o1, o3, o4-mini series). Cannot be used with maxTokens.* | -\n| spring.ai.azure.openai.chat.options.temperature | The sampling temperature to use that controls the apparent creativity of generated completions. Higher values will make output more random while lower values will make results more focused and deterministic. It is not recommended to modify temperature and top_p for the same completions request as the interaction of these two settings is difficult to predict. | -\n| spring.ai.azure.openai.chat.options.topP | An alternative to sampling with temperature called nucleus sampling. This value causes the model to consider the results of tokens with the provided probability mass. | -\n| spring.ai.azure.openai.chat.options.logitBias | A map between GPT token IDs and bias scores that influences the probability of specific tokens appearing in a completions response. Token IDs are computed via external tokenizer tools, while bias scores reside in the range of -100 to 100 with minimum and maximum values corresponding to a full ban or exclusive selection of a token, respectively. The exact behavior of a given bias score varies by model. | -\n| spring.ai.azure.openai.chat.options.user | An identifier for the caller or end user of the operation. This may be used for tracking or rate-limiting purposes. | -\n| spring.ai.azure.openai.chat.options.stream-usage | (For streaming only) Set to add an additional chunk with token usage statistics for the entire request. The `choices` field for this chunk is an empty array and all other chunks will also include a usage field, but with a null value. | false\n| spring.ai.azure.openai.chat.options.n | The number of chat completions choices that should be generated for a chat completions response. | -\n| spring.ai.azure.openai.chat.options.stop | A collection of textual sequences that will end completions generation. | -\n| spring.ai.azure.openai.chat.options.presencePenalty |  A value that influences the probability of generated tokens appearing based on their existing presence in generated text. Positive values will make tokens less likely to appear when they already exist and increase the model's likelihood to output new topics. | -\n| spring.ai.azure.openai.chat.options.responseFormat.type | Compatible with `GPT-4o`, `GPT-4o mini`, `GPT-4 Turbo` and all `GPT-3.5 Turbo` models newer than `gpt-3.5-turbo-1106`.\nThe `JSON_OBJECT` type enables JSON mode, which guarantees the message the model generates is valid JSON.\nThe `JSON_SCHEMA` type enables Structured Outputs which guarantees the model will match your supplied JSON schema. The `JSON_SCHEMA` type requires setting the `responseFormat.schema` property as well. | -\n| spring.ai.azure.openai.chat.options.responseFormat.schema | Response format JSON schema. Applicable only for `responseFormat.type=JSON_SCHEMA` | -\n| spring.ai.azure.openai.chat.options.frequencyPenalty | A value that influences the probability of generated tokens appearing based on their cumulative frequency in generated text. Positive values will make tokens less likely to appear as their frequency increases and decrease the likelihood of the model repeating the same statements verbatim. | -\n| spring.ai.azure.openai.chat.options.tool-names | List of tools, identified by their names, to enable for function calling in a single prompt request. Tools with those names must exist in the ToolCallback registry. | -\n| spring.ai.azure.openai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | -\n| spring.ai.azure.openai.chat.options.internal-tool-execution-enabled | If false, the Spring AI will not handle the tool calls internally, but will proxy them to the client. Then it is the client's responsibility to handle the tool calls, dispatch them to the appropriate function, and return the results. If true (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support | true\n|====\n\nTIP: All properties prefixed with `spring.ai.azure.openai.chat.options` can be overridden at runtime by adding a request specific <<chat-options>> to the `Prompt` call.\n\n=== Token Limit Parameters: Model-Specific Usage\n\nAzure OpenAI has model-specific requirements for token limiting parameters:\n\n[cols=\"1,1,2\", options=\"header\"]\n|====\n| Model Family | Required Parameter | Notes\n\n| **Reasoning Models** +\n(o1, o3, o4-mini series)\n| `maxCompletionTokens`\n| These models only accept `maxCompletionTokens`. Using `maxTokens` will result in an API error.\n\n| **Non-Reasoning Models** +\n(gpt-4o, gpt-3.5-turbo, etc.)\n| `maxTokens`\n| Traditional models use `maxTokens` for output limiting. Using `maxCompletionTokens` may result in an API error.\n|====\n\nIMPORTANT: The parameters `maxTokens` and `maxCompletionTokens` are **mutually exclusive**. Setting both parameters simultaneously will result in an API error from Azure OpenAI. The Spring AI Azure OpenAI client will automatically clear the previously set parameter when you set the other one, with a warning message.\n\n.Example: Using maxCompletionTokens for reasoning models\n[source,java]\n----\nvar options = AzureOpenAiChatOptions.builder()\n    .deploymentName(\"o1-preview\")\n    .maxCompletionTokens(500)  // Required for reasoning models\n    .build();\n----\n\n.Example: Using maxTokens for non-reasoning models\n[source,java]\n----\nvar options = AzureOpenAiChatOptions.builder()\n    .deploymentName(\"gpt-4o\")\n    .maxTokens(500)  // Required for non-reasoning models\n    .build();\n----\n\n== Runtime Options [[chat-options]]\n\nThe link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-azure-openai/src/main/java/org/springframework/ai/azure/openai/AzureOpenAiChatOptions.java[AzureOpenAiChatOptions.java] provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.\n\nOn start-up, the default options can be configured with the `AzureOpenAiChatModel(api, options)` constructor or the `spring.ai.azure.openai.chat.options.*` properties.\n\nAt runtime you can override the default options by adding new, request specific, options to the `Prompt` call.\nFor example to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        AzureOpenAiChatOptions.builder()\n            .deploymentName(\"gpt-4o\")\n            .temperature(0.4)\n        .build()\n    ));\n----\n\nTIP: In addition to the model specific link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-azure-openai/src/main/java/org/springframework/ai/azure/openai/AzureOpenAiChatOptions.java[AzureOpenAiChatOptions.java] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n\n== Function Calling\n\nYou can register custom Java functions with the AzureOpenAiChatModel and have the model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions.\nThis is a powerful technique to connect the LLM capabilities with external tools and APIs.\nRead more about xref:api/tools.adoc[Tool Calling].\n\n== Multimodal\n\nMultimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats.\nPresently, the Azure OpenAI `gpt-4o` model offers multimodal support.\n\nThe Azure OpenAI can incorporate a list of base64-encoded images or image urls with the message.\nSpring AI’s link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/messages/Message.java[Message] interface facilitates multimodal AI models by introducing the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-commons/src/main/java/org/springframework/ai/content/Media.java[Media] type.\nThis type encompasses data and details regarding media attachments in messages, utilizing Spring’s `org.springframework.util.MimeType` and a `java.lang.Object` for the raw media data.\n\nBelow is a code example excerpted from link:https://github.com/spring-projects/spring-ai/blob/c9a3e66f90187ce7eae7eb78c462ec622685de6c/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/chat/OpenAiChatModelIT.java#L293[OpenAiChatModelIT.java], illustrating the fusion of user text with an image using the `GPT_4_O` model.\n\n[source,java]\n----\nURL url = new URL(\"https://docs.spring.io/spring-ai/reference/_images/multimodal.test.png\");\nString response = ChatClient.create(chatModel).prompt()\n        .options(AzureOpenAiChatOptions.builder().deploymentName(\"gpt-4o\").build())\n        .user(u -> u.text(\"Explain what do you see on this picture?\").media(MimeTypeUtils.IMAGE_PNG, this.url))\n        .call()\n        .content();\n----\n\nTIP: you can pass multiple images as well.\n\nIt takes as an input the `multimodal.test.png` image:\n\nimage::multimodal.test.png[Multimodal Test Image, 200, 200, align=\"left\"]\n\nalong with the text message \"Explain what do you see on this picture?\", and generates a response like this:\n\n----\nThis is an image of a fruit bowl with a simple design. The bowl is made of metal with curved wire edges that\ncreate an open structure, allowing the fruit to be visible from all angles. Inside the bowl, there are two\nyellow bananas resting on top of what appears to be a red apple. The bananas are slightly overripe, as\nindicated by the brown spots on their peels. The bowl has a metal ring at the top, likely to serve as a handle\nfor carrying. The bowl is placed on a flat surface with a neutral-colored background that provides a clear\nview of the fruit inside.\n----\n\nYou can also pass in a classpath resource instead of a URL as shown in the example below\n\n[source,java]\n----\nResource resource = new ClassPathResource(\"multimodality/multimodal.test.png\");\n\nString response = ChatClient.create(chatModel).prompt()\n    .options(AzureOpenAiChatOptions.builder()\n    .deploymentName(\"gpt-4o\").build())\n    .user(u -> u.text(\"Explain what do you see on this picture?\")\n    .media(MimeTypeUtils.IMAGE_PNG, this.resource))\n    .call()\n    .content();\n----\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-azure-openai` to your pom (or gradle) dependencies.\n\nAdd a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model:\n\n[source,application.properties]\n----\nspring.ai.azure.openai.api-key=YOUR_API_KEY\nspring.ai.azure.openai.endpoint=YOUR_ENDPOINT\nspring.ai.azure.openai.chat.options.deployment-name=gpt-4o\nspring.ai.azure.openai.chat.options.temperature=0.7\n----\n\nTIP: replace the `api-key` and `endpoint` with your Azure OpenAI credentials.\n\nThis will create a `AzureOpenAiChatModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the chat model for text generations.\n\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final AzureOpenAiChatModel chatModel;\n\n    @Autowired\n    public ChatController(AzureOpenAiChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return this.chatModel.stream(prompt);\n    }\n}\n----\n\n== Manual Configuration\n\nThe link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-azure-openai/src/main/java/org/springframework/ai/azure/openai/AzureOpenAiChatModel.java[AzureOpenAiChatModel] implements the `ChatModel` and `StreamingChatModel` and uses the link:https://learn.microsoft.com/en-us/java/api/overview/azure/ai-openai-readme?view=azure-java-preview[Azure OpenAI Java Client].\n\nTo enable it, add the `spring-ai-azure-openai` dependency to your project's Maven `pom.xml` file:\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-azure-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,gradle]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-azure-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nTIP: The `spring-ai-azure-openai` dependency also provide the access to the `AzureOpenAiChatModel`. For more information about the `AzureOpenAiChatModel` refer to the link:../chat/azure-openai-chat.html[Azure OpenAI Chat] section.\n\nNext, create an `AzureOpenAiChatModel` instance and use it to generate text responses:\n\n[source,java]\n----\nvar openAIClientBuilder = new OpenAIClientBuilder()\n  .credential(new AzureKeyCredential(System.getenv(\"AZURE_OPENAI_API_KEY\")))\n  .endpoint(System.getenv(\"AZURE_OPENAI_ENDPOINT\"));\n\nvar openAIChatOptions = AzureOpenAiChatOptions.builder()\n  .deploymentName(\"gpt-5\")\n  .temperature(0.4)\n  .maxCompletionTokens(200)\n  .build();\n\nvar chatModel = AzureOpenAiChatModel.builder()\n\t\t\t\t.openAIClientBuilder(openAIClientBuilder)\n\t\t\t\t.defaultOptions(openAIChatOptions)\n\t\t\t\t.build();\n\nChatResponse response = chatModel.call(\n  new Prompt(\"Generate the names of 5 famous pirates.\"));\n\n// Or with streaming responses\nFlux<ChatResponse> streamingResponses = chatModel.stream(\n  new Prompt(\"Generate the names of 5 famous pirates.\"));\n\n----\n\nNOTE: the `gpt-4o` is actually the `Deployment Name` as presented in the Azure AI Portal.\n"

You should be able to obtain your access and security keys.\n\n* Enable the Models to use: Go to link:https://us-east-1.console.aws.amazon.com/bedrock/home[Amazon Bedrock] and from the link:https://us-east-1.console.aws.amazon.com/bedrock/home?region=us-east-1#/modelaccess[Model Access] menu on the left, configure access to the models you are going to use.\n\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nAdd the `spring-ai-starter-model-bedrock-converse` dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files:\n\n[tabs]\n======\nMaven::\n+\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-bedrock-converse</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,gradle]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-bedrock-converse'\n}\n----\n======\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n\n=== Chat Properties\n\nThe prefix `spring.ai.bedrock.aws` is the property prefix to configure the connection to AWS Bedrock.\n\n[cols=\"3,3,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.bedrock.aws.region     | AWS region to use  | us-east-1\n| spring.ai.bedrock.aws.timeout    | AWS max duration for entire API call | 5m\n| spring.ai.bedrock.aws.connectionTimeout | Max duration to wait while establishing connection | 5s\n| spring.ai.bedrock.aws.connectionAcquisitionTimeout | Max duration to wait for new connection from the pool | 30s\n| spring.ai.bedrock.aws.asyncReadTimeout | Max duration spent reading asynchronous responses | 30s\n| spring.ai.bedrock.aws.access-key | AWS access key  | -\n| spring.ai.bedrock.aws.secret-key | AWS secret key  | -\n| spring.ai.bedrock.aws.session-token | AWS session token for temporary credentials | -\n| spring.ai.bedrock.aws.profile.name | AWS profile name.  | -\n| spring.ai.bedrock.aws.profile.credentials-path | AWS credentials file path.  | -\n| spring.ai.bedrock.aws.profile.configuration-path | AWS config file path.  | -\n|====\n\n[NOTE]\n====\nEnabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`.\n\nTo enable, spring.ai.model.chat=bedrock-converse (It is enabled by default)\n\nTo disable, spring.ai.model.chat=none (or any value which doesn't match bedrock-converse)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix `spring.ai.bedrock.converse.chat` is the property prefix that configures the chat model implementation for the Converse API.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.bedrock.converse.chat.enabled (Removed and no longer valid) | Enable Bedrock Converse chat model. | true\n| spring.ai.model.chat | Enable Bedrock Converse chat model. | bedrock-converse\n| spring.ai.bedrock.converse.chat.options.model | The model ID to use. You can use the https://docs.aws.amazon.com/bedrock/latest/userguide/conversation-inference-supported-models-features.html[Supported models and model features]  | None. Select your https://us-east-1.console.aws.amazon.com/bedrock/home?region=us-east-1#/models[modelId] from the AWS Bedrock console.\n| spring.ai.bedrock.converse.chat.options.temperature | Controls the randomness of the output.

Return temperature in 36°F or 36°C format. Use multi-turn if needed.\")\n            .inputType(WeatherService.Request.class)\n            .build()))\n        .build();\n\nString response = ChatClient.create(this.chatModel)\n    .prompt(\"What is current weather in Amsterdam?\")\n    .options(options)\n    .call()\n    .content();\n----\n\n== Prompt Caching\n\nAWS Bedrock's https://docs.aws.amazon.com/bedrock/latest/userguide/prompt-caching.html[prompt caching feature] allows you to cache frequently used prompts to reduce costs and improve response times for repeated interactions.\nWhen you cache a prompt, subsequent identical requests can reuse the cached content, significantly reducing the number of input tokens processed.\n\n[NOTE]\n====\n*Supported Models*\n\nPrompt caching is supported on Claude 3.x, Claude 4.x, and Amazon Nova models available through AWS Bedrock.\n\n*Token Requirements*\n\nDifferent models have different minimum token thresholds for cache effectiveness:\n- Claude Sonnet 4 and most models: 1024+ tokens\n- Model-specific requirements may vary - consult AWS Bedrock documentation\n====\n\n=== Cache Strategies\n\nSpring AI provides strategic cache placement through the `BedrockCacheStrategy` enum:\n\n* `NONE`: Disables prompt caching completely (default)\n* `SYSTEM_ONLY`: Caches only the system message content\n* `TOOLS_ONLY`: Caches tool definitions only (Claude models only)\n* `SYSTEM_AND_TOOLS`: Caches both system message and tool definitions (Claude models only)\n* `CONVERSATION_HISTORY`: Caches entire conversation history in chat memory scenarios\n\nThis strategic approach ensures optimal cache breakpoint placement while staying within AWS Bedrock's 4-breakpoint limit.\n\n[NOTE]\n====\n*Amazon Nova Limitations*\n\nAmazon Nova models (Nova Micro, Lite, Pro, Premier) only support caching for `system` and `messages` content.\nThey do **not** support caching for `tools`.\n\nIf you attempt to use `TOOLS_ONLY` or `SYSTEM_AND_TOOLS` strategies with Nova models, AWS will return a `ValidationException`.\nUse `SYSTEM_ONLY` strategy for Amazon Nova models.\n====\n\n=== Enabling Prompt Caching\n\nEnable prompt caching by setting `cacheOptions` on `BedrockChatOptions` and choosing a `strategy`.\n\n==== System-Only Caching\n\nThe most common use case - cache system instructions across multiple requests:\n\n[source,java]\n----\n// Cache system message content\nChatResponse response = chatModel.call(\n    new Prompt(\n        List.of(\n            new SystemMessage(\"You are a helpful AI assistant with extensive knowledge...\"),\n            new UserMessage(\"What is machine learning?\")\n        ),\n        BedrockChatOptions.builder()\n            .model(\"us.anthropic.claude-haiku-4-5-20251001-v1:0\")\n            .cacheOptions(BedrockCacheOptions.builder()\n                .strategy(BedrockCacheStrategy.SYSTEM_ONLY)\n                .build())\n            .maxTokens(500)\n            .build()\n    )\n);\n----\n\n==== Tools-Only Caching\n\nCache large tool definitions while keeping system prompts dynamic (Claude models only):\n\n[source,java]\n----\n// Cache tool definitions only\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"What's the weather in San Francisco?\",\n        BedrockChatOptions.builder()\n            .model(\"us.anthropic.claude-haiku-4-5-20251001-v1:0\")\n            .cacheOptions(BedrockCacheOptions.builder()\n                .strategy(BedrockCacheStrategy.TOOLS_ONLY)\n                .build())\n            .toolCallbacks(weatherToolCallbacks)  // Large tool definitions\n            .maxTokens(500)\n            .build()\n    )\n);\n----\n\nNOTE: This strategy is only supported on Claude models.\nAmazon Nova models will return a `ValidationException`.\n\n==== System and Tools Caching\n\nCache both system instructions and tool definitions for maximum reuse (Claude models only):\n\n[source,java]\n----\n// Cache system message and tool definitions\nChatResponse response = chatModel.call(\n    new Prompt(\n        List.of(\n            new SystemMessage(\"You are a weather analysis assistant...\"),\n            new UserMessage(\"What's the weather like in Tokyo?\")\n        ),\n        BedrockChatOptions.builder()\n            .model(\"us.anthropic.claude-haiku-4-5-20251001-v1:0\")\n            .cacheOptions(BedrockCacheOptions.builder()\n                .strategy(BedrockCacheStrategy.SYSTEM_AND_TOOLS)\n                .build())\n            .toolCallbacks(weatherToolCallbacks)\n            .maxTokens(500)\n            .build()\n    )\n);\n----\n\nNOTE: This strategy uses 2 cache breakpoints (one for tools, one for system).\nOnly supported on Claude models.\n\n==== Conversation History Caching\n\nCache growing conversation history for multi-turn chatbots and assistants:\n\n[source,java]\n----\n// Cache conversation history with ChatClient and memory\nChatClient chatClient = ChatClient.builder(chatModel)\n    .defaultSystem(\"You are a personalized career counselor...\")\n    .defaultAdvisors(MessageChatMemoryAdvisor.builder(chatMemory)\n        .conversationId(conversationId)\n        .build())\n    .build();\n\nString response = chatClient.prompt()\n    .user(\"What career advice would you give me?\")\n    .options(BedrockChatOptions.builder()\n        .model(\"us.anthropic.claude-haiku-4-5-20251001-v1:0\")\n        .cacheOptions(BedrockCacheOptions.builder()\n            .strategy(BedrockCacheStrategy.CONVERSATION_HISTORY)\n            .build())\n        .maxTokens(500)\n        .build())\n    .call()\n    .content();\n----\n\n==== Using ChatClient Fluent API\n\n[source,java]\n----\nString response = ChatClient.create(chatModel)\n    .prompt()\n    .system(\"You are an expert document analyst...\")\n    .user(\"Analyze this large document: \" + document)\n    .options(BedrockChatOptions.builder()\n        .model(\"us.anthropic.claude-haiku-4-5-20251001-v1:0\")\n        .cacheOptions(BedrockCacheOptions.builder()\n            .strategy(BedrockCacheStrategy.SYSTEM_ONLY)\n            .build())\n        .build())\n    .call()\n    .content();\n----\n\n=== Usage Example\n\nHere's a complete example demonstrating prompt caching with cost tracking:\n\n[source,java]\n----\n// Create system content that will be reused multiple times\nString largeSystemPrompt = \"You are an expert software architect specializing in distributed systems...\";\n// (Ensure this is 1024+ tokens for cache effectiveness)\n\n// First request -

Use `SYSTEM_ONLY` for reusable system prompts and instructions (works with all models)\n   - Use `TOOLS_ONLY` when you have large stable tools but dynamic system prompts (Claude only)\n   - Use `SYSTEM_AND_TOOLS` when both system and tools are large and stable (Claude only)\n   - Use `CONVERSATION_HISTORY` with ChatClient memory for multi-turn conversations\n   - Use `NONE` to explicitly disable caching\n\n2. **Meet Token Requirements**: Focus on caching content that meets the minimum token requirements (1024+ tokens for most models).\n\n3. **Reuse Identical Content**: Caching works best with exact matches of prompt content.\nEven small changes will require a new cache entry.\n\n4. **Monitor Token Usage**: Track cache effectiveness using the metadata metrics:\n\n   Integer cacheWrite = (Integer) response.getMetadata().getMetadata().get(\"cacheWriteInputTokens\");\n   Integer cacheRead = (Integer) response.getMetadata().getMetadata().get(\"cacheReadInputTokens\");\n   if (cacheRead != null && cacheRead > 0) {\n       System.out.println(\"Cache hit: \" + cacheRead + \" tokens saved\");\n   }\n\n5. **Strategic Cache Placement**: The implementation automatically places cache breakpoints at optimal locations based on your chosen strategy, ensuring compliance with AWS Bedrock's 4-breakpoint limit.\n\n6. **Cache Lifetime**: AWS Bedrock caches have a fixed 5-minute TTL (Time To Live).\nEach cache access resets the timer.\n\n7. **Model Compatibility**: Be aware of model-specific limitations:\n   - **Claude models**: Support all caching strategies\n   - **Amazon Nova models**: Only support `SYSTEM_ONLY` and `CONVERSATION_HISTORY` (tool caching not supported)\n\n8. **Tool Stability**: When using `TOOLS_ONLY`, `SYSTEM_AND_TOOLS`, or `CONVERSATION_HISTORY` strategies, ensure tools remain stable.\nChanging tool definitions will invalidate all downstream cache breakpoints due to cascade invalidation.\n\n=== Cache Invalidation and Cascade Behavior\n\nAWS Bedrock follows a hierarchical cache model with cascade invalidation:\n\n**Cache Hierarchy**: `Tools → System → Messages`\n\nChanges at each level invalidate that level and all subsequent levels:\n\n[cols=\"1,1,1,1\", stripes=even]\n|====\n| What Changes | Tools Cache | System Cache | Messages Cache\n\n| Tools | ❌ Invalid | ❌ Invalid | ❌ Invalid\n| System | ✅ Valid | ❌ Invalid | ❌ Invalid\n| Messages | ✅ Valid | ✅ Valid | ❌ Invalid\n|====\n\n**Example with `SYSTEM_AND_TOOLS` strategy**:\n\n[source,java]\n----\n// Request 1: Cache both tools and system\nChatResponse r1 = chatModel.call(\n    new Prompt(\n        List.of(new SystemMessage(\"System prompt\"), new UserMessage(\"Question\")),\n        BedrockChatOptions.builder()\n            .cacheOptions(BedrockCacheOptions.builder()\n                .strategy(BedrockCacheStrategy.SYSTEM_AND_TOOLS)\n                .build())\n            .toolCallbacks(tools)\n            .build()\n    )\n);\n// Result: Both caches created\n\n// Request 2: Change only system prompt (tools same)\nChatResponse r2 = chatModel.call(\n    new Prompt(\n        List.of(new SystemMessage(\"DIFFERENT system prompt\"), new UserMessage(\"Question\")),\n        BedrockChatOptions.builder()\n            .cacheOptions(BedrockCacheOptions.builder()\n                .strategy(BedrockCacheStrategy.SYSTEM_AND_TOOLS)\n                .build())\n            .toolCallbacks(tools) // SAME tools\n            .build()\n    )\n);\n// Result: Tools cache HIT (reused), system cache MISS (recreated)\n\n// Request 3: Change tools (system same as Request 2)\nChatResponse r3 = chatModel.call(\n    new Prompt(\n        List.of(new SystemMessage(\"DIFFERENT system prompt\"), new UserMessage(\"Question\")),\n        BedrockChatOptions.builder()\n            .cacheOptions(BedrockCacheOptions.builder()\n                .strategy(BedrockCacheStrategy.SYSTEM_AND_TOOLS)\n                .build())\n            .toolCallbacks(newTools) // DIFFERENT tools\n            .build()\n    )\n);\n// Result: BOTH caches MISS (tools change invalidates everything downstream)\n----\n\n=== Implementation Details\n\nThe prompt caching implementation in Spring AI follows these key design principles:\n\n1. **Strategic Cache Placement**: Cache breakpoints are automatically placed at optimal locations based on the chosen strategy, ensuring compliance with AWS Bedrock's 4-breakpoint limit.\n\n2. **Provider Portability**: Cache configuration is done through `BedrockChatOptions` rather than individual messages, preserving compatibility when switching between different AI providers.\n\n3. **Thread Safety**: The cache breakpoint tracking is implemented with thread-safe mechanisms to handle concurrent requests correctly.\n\n4. **UNION Type Pattern**: AWS SDK uses UNION types where cache points are added as separate blocks rather than properties.\nThis is different from direct API approaches but ensures type safety and API compliance.\n\n5. **Incremental Caching**: The `CONVERSATION_HISTORY` strategy places cache breakpoints on the last user message, enabling incremental caching where each conversation turn builds on the previous cached prefix.\n\n=== Cost Considerations\n\nAWS Bedrock pricing for prompt caching (approximate, varies by model):\n\n* **Cache writes**: ~25% more expensive than base input tokens\n* **Cache reads**: ~90% cheaper (only 10% of base input token price)\n* **Break-even point**: After just 1 cache read, you've saved money\n\n**Example cost calculation**:\n\n[source,java]\n----\n// System prompt: 2000 tokens\n// User question: 50 tokens\n\n// Without caching (5 requests):\n// Cost: 5 × (2000 + 50) = 10,250 tokens at base rate\n\n// With caching (5 requests):\n// Request 1: 2000 tokens × 1.25 (cache write) + 50 = 2,550 tokens\n// Requests 2-5: 4 × (2000 × 0.10 (cache read) + 50) = 4 × 250 = 1,000 tokens\n// Total: 2,550 + 1,000 = 3,550 tokens equivalent\n\n// Savings: (10,250 - 3,550) / 10,250 = 65% cost reduction\n----\n\n== Tool Calling\n\nThe Bedrock Converse API supports tool calling capabilities, allowing models to use tools during conversations.\nHere's an example of how to define and use @Tool based tools:\n\n[source,java]\n----\n\npublic class WeatherService {\n\n    @Tool(description = \"Get the weather in location\")\n    public String weatherByLocation(@ToolParam(description= \"City or state name\") String location) {\n        ...\n    }\n}\n\nString response = ChatClient.create(this.chatModel)\n        .prompt(\"What's the weather like in Boston?\")\n        .tools(new WeatherService())\n        .call()\n        .content();\n----\n\nYou can use the java.util.function beans as tools as well:\n\n[source,java]\n----\n@Bean\n@Description(\"Get the weather in location. Return temperature in 36°F or 36°C format.\")\npublic Function<Request, Response> weatherFunction() {\n    return new MockWeatherService();\n}\n\nString response = ChatClient.create(this.chatModel)\n        .prompt(\"What's the weather like in Boston?\")\n        .toolNames(\"weatherFunction\")\n        .inputType(Request.class)\n        .call()\n        .content();\n----\n\nFind more in xref:api/tools.adoc[Tools] documentation.\n\n== Structured Output [[structured-output]]\n\nAWS Bedrock supports native structured outputs through JSON Schema, ensuring the model generates responses that strictly conform to your specified structure.\nThis feature is available for link:https://docs.aws.amazon.com/bedrock/latest/userguide/conversation-inference-supported-models-features.html[supported models] including Anthropic Claude and Amazon Nova.\n\n=== Using ChatClient with Native Structured Output\n\nThe simplest way to use structured output is with the `ChatClient` high-level API and the `ENABLE_NATIVE_STRUCTURED_OUTPUT` advisor:\n\n[source,java]\n----\nrecord ActorsFilms(String actor, List<String> movies) {}\n\nActorsFilms actorsFilms = ChatClient.create(chatModel).prompt()\n    .options(ToolCallingChatOptions.builder()\n        .model(\"us.anthropic.claude-haiku-4-5-20251001-v1:0\")\n        .build())\n    .advisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT)\n    .user(\"Generate the filmography for a random actor.\")\n    .call()\n    .entity(ActorsFilms.class);\n----\n\nThis approach automatically:\n\n- Generates a JSON schema from your Java class\n- Sets the `outputSchema` on `BedrockChatOptions` via the AWS Bedrock `OutputConfig` API\n- Parses the JSON response into your specified type\n\n=== Using outputSchema Directly\n\nFor more control, you can set the JSON schema directly on `BedrockChatOptions`:\n\n[source,java]\n----\nString jsonSchema = \"\"\"\n        {\n            \"type\": \"object\",\n            \"properties\": {\n                \"actor\": { \"type\": \"string\" },\n                \"movies\": {\n                    \"type\": \"array\",\n                    \"items\": { \"type\": \"string\" }\n                }\n            },\n            \"required\": [\"actor\", \"movies\"],\n            \"additionalProperties\": false\n        }\n        \"\"\";\n\nChatResponse response = chatModel.call(\n    new Prompt(\"Generate the filmography for a random actor.\",\n        BedrockChatOptions.builder()\n            .model(\"us.anthropic.claude-haiku-4-5-20251001-v1:0\")\n            .outputSchema(jsonSchema)\n            .build()));\n\nString content = response.getResult().getOutput().getText();\n----\n\nNOTE: AWS Bedrock structured output uses a fixed schema name `response_schema` internally when constructing the `OutputConfig`.\nThe schema JSON is passed directly to the AWS SDK's `JsonSchemaDefinition`.\n\nFor more information, see the xref:api/structured-output-converter.adoc[Structured Output Converter] documentation.\n\n== Multimodal\n\nMultimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, video, pdf, doc, html, md and more data formats.\n\nThe Bedrock Converse API supports multimodal inputs, including text and image inputs, and can generate a text response based on the combined input.\n\nYou need a model that supports multimodal inputs, such as the Anthropic Claude or Amazon Nova models.\n\n=== Images\n\nFor link:https://docs.aws.amazon.com/bedrock/latest/userguide/conversation-inference-supported-models-features.html[models] that support vision multimodality, such as Amazon Nova, Anthropic Claude, Llama 3.2, the Bedrock Converse API Amazon allows you to include multiple images in the payload. Those models can analyze the passed images and answer questions, classify an image, as well as summarize images based on provided instructions.\n\nCurrently, Bedrock Converse supports the `base64` encoded images of `image/jpeg`, `image/png`, `image/gif` and `image/webp` mime types.\n\nSpring AI's `Message` interface supports multimodal AI models by introducing the `Media` type.\nIt contains data and information about media attachments in messages, using Spring's `org.springframework.util.MimeType` and a `java.lang.Object` for the raw media data.\n\nBelow is a simple code example, demonstrating the combination of user text with an image.\n\n[source,java]\n----\nString response = ChatClient.create(chatModel)\n    .prompt()\n    .user(u -> u.text(\"Explain what do you see on this picture?\")\n        .media(Media.Format.IMAGE_PNG, new ClassPathResource(\"/test.png\")))\n    .call()\n    .content();\n\nlogger.info(response);\n----\n\nIt takes as an input the `test.png` image:\n\nimage::multimodal.test.png[Multimodal Test Image, 200, 200, align=\"left\"]\n\nalong with the text message \"Explain what do you see on this picture?\", and generates a response something like:\n\n----\nThe image shows a close-up view of a wire fruit basket containing several pieces of fruit.\n...\n----\n\n=== Video\n\nThe link:https://docs.aws.amazon.com/nova/latest/userguide/modalities-video.html[Amazon Nova models] allow you to include a single video in the payload, which can be provided either in base64 format or through an Amazon S3 URI.\n\nCurrently, Bedrock Nova supports the videos of `video/x-matroska`, `video/quicktime`, `video/mp4`, `video/webm`, `video/x-flv`, `video/mpeg`, `video/x-ms-wmv` and `video/3gpp` mime types.\n\nSpring AI's `Message` interface supports multimodal AI models by introducing the `Media` type.\nIt contains data and information about media attachments in messages, using Spring's `org.springframework.util.MimeType` and a `java.lang.Object` for the raw media data.\n\nBelow is a simple code example, demonstrating the combination of user text with a video.\n\n[source,java]\n----\nString response = ChatClient.create(chatModel)\n    .prompt()\n    .user(u -> u.text(\"Explain what do you see in this video?\")\n        .media(Media.Format.VIDEO_MP4, new ClassPathResource(\"/test.video.mp4\")))\n    .call()\n    .content();\n\nlogger.info(response);\n----\n\nIt takes as an input the `test.video.mp4` image:\n\nimage::test.video.jpeg[Multimodal Test Video, 200, 200, align=\"left\"]\n\nalong with the text message \"Explain what do you see in this video?\", and generates a response something like:\n\n----\nThe video shows a group of baby chickens, also known as chicks, huddled together on a surface\n...\n----\n\n=== Documents\n\nFor some models, Bedrock allows you to include documents in the payload through Converse API document support, which can be provided in bytes.\nThe document support has two different variants as explained below:\n\n- **Text document types** (txt, csv, html, md, and so on), where the emphasis is on text understanding. These use case include answering based on textual elements of the document.\n- **Media document types** (pdf, docx, xlsx), where the emphasis is on vision-based understanding to answer questions. These use cases include answering questions based on charts, graphs, and so on.\n\nCurrently the Anthropic link:https://docs.anthropic.com/en/docs/build-with-claude/pdf-support[PDF support (beta)] and Amazon Bedrock Nova models support document multimodality.\n\nBelow is a simple code example, demonstrating the combination of user text with a media document.\n\n[source,java]\n----\nString response = ChatClient.create(chatModel)\n    .prompt()\n    .user(u -> u.text(\n            \"You are a very professional document summarization specialist. Please summarize the given document.\")\n        .media(Media.Format.DOC_PDF, new ClassPathResource(\"/spring-ai-reference-overview.pdf\")))\n    .call()\n    .content();\n\nlogger.info(response);\n----\n\nIt takes as an input the `spring-ai-reference-overview.pdf` document:\n\nimage::test.pdf.png[Multimodal Test PNG, 200, 200, align=\"left\"]\n\nalong with the text message \"You are a very professional document summarization specialist. Please summarize the given document.\", and generates a response something like:\n\n----\n**Introduction:**\n- Spring AI is designed to simplify the development of applications with artificial intelligence (AI) capabilities, aiming to avoid unnecessary complexity.\n...\n----\n\n\n== Sample Controller\n\nCreate a new Spring Boot project and add the `spring-ai-starter-model-bedrock-converse` to your dependencies.\n\nAdd an `application.properties` file under `src/main/resources`:\n\n[source,properties]\n----\nspring.ai.bedrock.aws.region=eu-central-1\nspring.ai.bedrock.aws.timeout=10m\nspring.ai.bedrock.aws.access-key=${AWS_ACCESS_KEY_ID}\nspring.ai.bedrock.aws.secret-key=${AWS_SECRET_ACCESS_KEY}\n# session token is only required for temporary credentials\nspring.ai.bedrock.aws.session-token=${AWS_SESSION_TOKEN}\n\nspring.ai.bedrock.converse.chat.options.temperature=0.8\nspring.ai.bedrock.converse.chat.options.top-k=15\n----\n\nHere's an example controller using the chat model:\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final ChatClient chatClient;\n\n    @Autowired\n    public ChatController(ChatClient.Builder builder) {\n        this.chatClient = builder.build();\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatClient.prompt(message).call().content());\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n    public Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return this.chatClient.prompt(message).stream().content();\n    }\n}\n----\n\n"

    "content": "= DeepSeek Chat\n\nSpring AI supports the various AI language models from DeepSeek. You can interact with DeepSeek language models and create a multilingual conversational assistant based on DeepSeek models.\n\n== Prerequisites\n\nYou will need to create an API key with DeepSeek to access DeepSeek language models.\n\nCreate an account at https://platform.deepseek.com/sign_up[DeepSeek registration page] and generate a token on the https://platform.deepseek.com/api_keys[API Keys page].\n\nThe Spring AI project defines a configuration property named `spring.ai.deepseek.api-key` that you should set to the value of the `API Key` obtained from the API Keys page.\n\nYou can set this configuration property in your `application.properties` file:\n\n[source,properties]\n----\nspring.ai.deepseek.api-key=<your-deepseek-api-key>\n----\n\nFor enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference a custom environment variable:\n\n[source,yaml]\n----\n# In application.yml\nspring:\n  ai:\n    deepseek:\n      api-key: ${DEEPSEEK_API_KEY}\n----\n\n[source,bash]\n----\n# In your environment or .env file\nexport DEEPSEEK_API_KEY=<your-deepseek-api-key>\n----\n\nYou can also set this configuration programmatically in your application code:\n\n[source,java]\n----\n// Retrieve API key from a secure source or environment variable\nString apiKey = System.getenv(\"DEEPSEEK_API_KEY\");\n----\n\n=== Add Repositories and BOM\n\nSpring AI artifacts are published in the Spring Milestone and Snapshot repositories.\nRefer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system.\n\nTo help with dependency management, Spring AI provides a BOM (bill of materials) to ensure that a consistent version of Spring AI is used throughout your entire project. Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build system.\n\n\n\n== Auto-configuration\n\nSpring AI provides Spring Boot auto-configuration for the DeepSeek Chat Model.\nTo enable it, add the following dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-deepseek</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-deepseek'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n=== Chat Properties\n\n==== Retry Properties\n\nThe prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the DeepSeek Chat model.\n\n[cols=\"3,5,1\"]\n|====\n| Property | Description | Default\n\n| spring.ai.retry.max-attempts   | Maximum number of retry attempts. |  10\n| spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. |  2 sec.\n| spring.ai.retry.backoff.multiplier | Backoff interval multiplier. |  5\n| spring.ai.retry.backoff.max-interval | Maximum backoff duration. |  3 min.\n| spring.ai.retry.on-client-errors | If false, throws a NonTransientAiException, and does not attempt a retry for `4xx` client error codes | false\n| spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty\n| spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty\n|====\n\n==== Connection Properties\n\nThe prefix `spring.ai.deepseek` is used as the property prefix that lets you connect to DeepSeek.\n\n[cols=\"3,5,1\"]\n|====\n| Property | Description | Default\n\n| spring.ai.deepseek.base-url   | The URL to connect to |  `+https://api.deepseek.com+`\n| spring.ai.deepseek.api-key    | The API Key           |  -\n|====\n\n==== Configuration Properties\n\nThe prefix `spring.ai.deepseek.chat` is the property prefix that lets you configure the chat model implementation for DeepSeek.\n\n[cols=\"3,5,1\"]\n|====\n| Property | Description | Default\n\n| spring.ai.deepseek.chat.enabled | Enables the DeepSeek chat model.  | true\n| spring.ai.deepseek.chat.base-url | Optionally overrides the spring.ai.deepseek.base-url to provide a chat-specific URL | `+https://api.deepseek.com/+`\n| spring.ai.deepseek.chat.api-key | Optionally overrides the spring.ai.deepseek.api-key to provide a chat-specific API key | -\n| spring.ai.deepseek.chat.completions-path | The path to the chat completions endpoint | `/chat/completions`\n| spring.ai.deepseek.chat.beta-prefix-path | The prefix path to the beta feature endpoint | `/beta`\n| spring.ai.deepseek.chat.options.model | ID of the model to use. You can use either deepseek-reasoner or deepseek-chat. | deepseek-chat\n| spring.ai.deepseek.chat.options.frequencyPenalty | Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim. | 0.0f\n| spring.ai.deepseek.chat.options.maxTokens | The maximum number of tokens to generate in the chat completion. The total length of input tokens and generated tokens is limited by the model's context length. | -\n| spring.ai.deepseek.chat.options.presencePenalty | Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics. |  0.0f\n| spring.ai.deepseek.chat.options.stop | Up to 4 sequences where the API will stop generating further tokens. | -\n| spring.ai.deepseek.chat.options.temperature | Which sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p, but not both. | 1.0F\n| spring.ai.deepseek.chat.options.topP | An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature, but not both. | 1.0F\n| spring.ai.deepseek.chat.options.logprobs | Whether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the content of the message. | -\n| spring.ai.deepseek.chat.options.topLogprobs | An integer between 0 and 20 specifying the number of most likely tokens to return at each token position, each with an associated log probability. logprobs must be set to true if this parameter is used. | -\n| spring.ai.deepseek.chat.options.tool-names | List of tools, identified by their names, to enable for function calling in a single prompt request. Tools with those names must exist in the ToolCallback registry. | -\n| spring.ai.deepseek.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | -\n| spring.ai.deepseek.chat.options.internal-tool-execution-enabled | If false, the Spring AI will not handle the tool calls internally, but will proxy them to the client. Then it is the client's responsibility to handle the tool calls, dispatch them to the appropriate function, and return the results. If true (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support | true\n|====\n\nNOTE: You can override the common `spring.ai.deepseek.base-url` and `spring.ai.deepseek.api-key` for the `ChatModel` implementations.\nThe `spring.ai.deepseek.chat.base-url` and `spring.ai.deepseek.chat.api-key` properties, if set, take precedence over the common properties.\nThis is useful if you want to use different DeepSeek accounts for different models and different model endpoints.\n\nTIP: All properties prefixed with `spring.ai.deepseek.chat.options` can be overridden at runtime by adding a request-specific <<chat-options>> to the `Prompt` call.\n\n== Runtime Options [[chat-options]]\n\nThe link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-deepseek/src/main/java/org/springframework/ai/deepseek/DeepSeekChatOptions.java[DeepSeekChatOptions.java] provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.\n\nOn startup, the default options can be configured with the `DeepSeekChatModel(api, options)` constructor or the `spring.ai.deepseek.chat.options.*` properties.\n\nAt runtime, you can override the default options by adding new, request-specific options to the `Prompt` call.\nFor example, to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates. Please provide the JSON response without any code block markers such as ```json```.\",\n        DeepSeekChatOptions.builder()\n            .withModel(DeepSeekApi.ChatModel.DEEPSEEK_CHAT.getValue())\n            .withTemperature(0.8f)\n        .build()\n    ));\n----\n\nTIP: In addition to the model-specific link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-deepseek/src/main/java/org/springframework/ai/deepseek/DeepSeekChatOptions.java[DeepSeekChatOptions], you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n== Sample Controller (Auto-configuration)\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-deepseek` to your pom (or gradle) dependencies.\n\nAdd an `application.properties` file under the `src/main/resources` directory to enable and configure the DeepSeek Chat model:\n\n[source,application.properties]\n----\nspring.ai.deepseek.api-key=YOUR_API_KEY\nspring.ai.deepseek.chat.options.model=deepseek-chat\nspring.ai.deepseek.chat.options.temperature=0.8\n----\n\nTIP: Replace the `api-key` with your DeepSeek credentials.\n\nThis will create a `DeepSeekChatModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the chat model for text generation.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final DeepSeekChatModel chatModel;\n\n    @Autowired\n    public ChatController(DeepSeekChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        var prompt = new Prompt(new UserMessage(message));\n        return chatModel.stream(prompt);\n    }\n}\n----\n\n== Chat Prefix Completion\nThe chat prefix completion follows the Chat Completion API, where users provide an assistant's prefix message for the model to complete the rest of the message.\n\nWhen using prefix completion, the user must ensure that the last message in the messages list is a DeepSeekAssistantMessage.\n\nBelow is a complete Java code example for chat prefix completion. In this example, we set the prefix message of the assistant to \"```python\\n\" to force the model to output Python code, and set the stop parameter to ['```'] to prevent additional explanations from the model.\n\n[source,java]\n----\n@RestController\npublic class CodeGenerateController {\n\n    private final DeepSeekChatModel chatModel;\n\n    @Autowired\n    public ChatController(DeepSeekChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generatePythonCode\")\n    public String generate(@RequestParam(value = \"message\", defaultValue = \"Please write quick sort code\") String message) {\n\t\tUserMessage userMessage = new UserMessage(message);\n\t\tMessage assistantMessage = DeepSeekAssistantMessage.prefixAssistantMessage(\"```python\\\\n\");\n\t\tPrompt prompt = new Prompt(List.of(userMessage, assistantMessage), ChatOptions.builder().stopSequences(List.of(\"```\")).build());\n\t\tChatResponse response = chatModel.call(prompt);\n\t\treturn response.getResult().getOutput().getText();\n    }\n}\n----\n\n== Reasoning Model (deepseek-reasoner)\nThe `deepseek-reasoner` is a reasoning model developed by DeepSeek. Before delivering the final answer, the model first generates a Chain of Thought (CoT) to enhance the accuracy of its responses. Our API provides users with access to the CoT content generated by `deepseek-reasoner`, enabling them to view, display, and distill it.\n\nYou can use the `DeepSeekAssistantMessage` to get the CoT content generated by `deepseek-reasoner`.\n[source,java]\n----\npublic void deepSeekReasonerExample() {\n    DeepSeekChatOptions promptOptions = DeepSeekChatOptions.builder()\n            .model(DeepSeekApi.ChatModel.DEEPSEEK_REASONER.getValue())\n            .build();\n    Prompt prompt = new Prompt(\"9.11 and 9.8, which is greater?\", promptOptions);\n    ChatResponse response = chatModel.call(prompt);\n\n    // Get the CoT content generated by deepseek-reasoner, only available when using deepseek-reasoner model\n    DeepSeekAssistantMessage deepSeekAssistantMessage = (DeepSeekAssistantMessage) response.getResult().getOutput();\n    String reasoningContent = deepSeekAssistantMessage.getReasoningContent();\n    String text = deepSeekAssistantMessage.getText();\n}\n----\n== Reasoning Model Multi-round Conversation\nIn each round of the conversation, the model outputs the CoT (reasoning_content) and the final answer (content). In the next round of the conversation, the CoT from previous rounds is not concatenated into the context, as illustrated in the following diagram:\n\nimage::deepseek_r1_multiround_example.png[Multimodal Test Image, align=\"center\"]\n\nPlease note that if the reasoning_content field is included in the sequence of input messages, the API will return a 400 error. Therefore, you should remove the reasoning_content field from the API response before making the API request, as demonstrated in the API example.\n[source,java]\n----\npublic String deepSeekReasonerMultiRoundExample() {\n    List<Message> messages = new ArrayList<>();\n    messages.add(new UserMessage(\"9.11 and 9.8, which is greater?\"));\n    DeepSeekChatOptions promptOptions = DeepSeekChatOptions.builder()\n            .model(DeepSeekApi.ChatModel.DEEPSEEK_REASONER.getValue())\n            .build();\n\n    Prompt prompt = new Prompt(messages, promptOptions);\n    ChatResponse response = chatModel.call(prompt);\n\n    DeepSeekAssistantMessage deepSeekAssistantMessage = (DeepSeekAssistantMessage) response.getResult().getOutput();\n    String reasoningContent = deepSeekAssistantMessage.getReasoningContent();\n    String text = deepSeekAssistantMessage.getText();\n\n    messages.add(AssistantMessage.builder().content(Objects.requireNonNull(text)).build());\n    messages.add(new UserMessage(\"How many Rs are there in the word 'strawberry'?\"));\n    Prompt prompt2 = new Prompt(messages, promptOptions);\n    ChatResponse response2 = chatModel.call(prompt2);\n\n    DeepSeekAssistantMessage deepSeekAssistantMessage2 = (DeepSeekAssistantMessage) response2.getResult().getOutput();\n    String reasoningContent2 = deepSeekAssistantMessage2.getReasoningContent();\n    return deepSeekAssistantMessage2.getText();\n}\n----\n\n== Manual Configuration\n\nThe link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-deepseek/src/main/java/org/springframework/ai/deepseek/DeepSeekChatModel.java[DeepSeekChatModel] implements the `ChatModel` and `StreamingChatModel` and uses the <<low-level-api>> to connect to the DeepSeek service.\n\nAdd the `spring-ai-deepseek` dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-deepseek</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-deepseek'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNext, create a `DeepSeekChatModel` and use it for text generation:\n\n[source,java]\n----\nDeepSeekApi deepSeekApi = DeepSeekApi.builder()\n        .apiKey(System.getenv(\"DEEPSEEK_API_KEY\"))\n        .build();\nDeepSeekChatOptions options = DeepSeekChatOptions.builder()\n        .model(DeepSeekApi.ChatModel.DEEPSEEK_CHAT.getValue())\n        .temperature(0.4)\n        .maxTokens(200)\n        .build();\nDeepSeekChatModel chatModel = DeepSeekChatModel.builder()\n        .deepSeekApi(deepSeekApi)\n        .defaultOptions(options)\n        .build();\nChatResponse response = chatModel.call(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n\n// Or with streaming responses\nFlux<ChatResponse> streamResponse = chatModel.stream(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n----\n\nThe `DeepSeekChatOptions` provides the configuration information for the chat requests.\nThe `DeepSeekChatOptions.Builder` is a fluent options builder.\n\n=== Low-level DeepSeekApi Client [[low-level-api]]\n\nThe link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-deepseek/src/main/java/org/springframework/ai/deepseek/api/DeepSeekApi.java[DeepSeekApi] is a lightweight Java client for link:https://platform.deepseek.com/api-docs/[DeepSeek API].\n\nHere is a simple snippet showing how to use the API programmatically:\n\n[source,java]\n----\nDeepSeekApi deepSeekApi =\n    new DeepSeekApi(System.getenv(\"DEEPSEEK_API_KEY\"));\n\nChatCompletionMessage chatCompletionMessage =\n    new ChatCompletionMessage(\"Hello world\", Role.USER);\n\n// Sync request\nResponseEntity<ChatCompletion> response = deepSeekApi.chatCompletionEntity(\n    new ChatCompletionRequest(List.of(chatCompletionMessage), DeepSeekApi.ChatModel.DEEPSEEK_CHAT.getValue(), 0.7, false));\n\n// Streaming request\nFlux<ChatCompletionChunk> streamResponse = deepSeekApi.chatCompletionStream(\n    new ChatCompletionRequest(List.of(chatCompletionMessage), DeepSeekApi.ChatModel.DEEPSEEK_CHAT.getValue(), 0.7, true));\n----\n\nFollow the https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-deepseek/src/main/java/org/springframework/ai/deepseek/api/DeepSeekApi.java[DeepSeekApi.java]'s JavaDoc for further information.\n\n==== DeepSeekApi Samples\n* The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-deepseek/src/test/java/org/springframework/ai/deepseek/api/DeepSeekApiIT.java[DeepSeekApiIT.java] test provides some general examples of how to use the lightweight library.\n"

Dependency names should now follow updated naming patterns for models, vector stores, and MCP starters.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the OpenAI Chat Client.\nTo enable it, add the following dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-openai</artifactId>\n</dependency>\n----\n\nor add the following to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n=== Chat Properties\n\n==== Retry Properties\n\nThe prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the OpenAI chat model.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.retry.max-attempts   | Maximum number of retry attempts. |  10\n| spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. |  2 sec.\n| spring.ai.retry.backoff.multiplier | Backoff interval multiplier. |  5\n| spring.ai.retry.backoff.max-interval | Maximum backoff duration. |  3 min.\n| spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false\n| spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty\n| spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty\n|====\n\n==== Connection Properties\n\nThe prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.openai.base-url   | The URL to connect to. Must be set to `https://hub.docker.com/u/ai` | -\n| spring.ai.openai.api-key    | Any string           |  -\n|====\n\n==== Configuration Properties\n\n[NOTE]\n====\nEnabling and disabling chat auto-configurations is now done via top level properties with the prefix `spring.ai.model.chat`.\n\nTo enable, `spring.ai.model.chat=openai` (It is enabled by default)\n\nTo disable, `spring.ai.model.chat=none` (or any value which doesn't match openai)\n\nThis change allows for the configuration of multiple models in your application.\n====\n\nThe prefix `spring.ai.openai.chat` is the property prefix that lets you configure the chat model implementation for OpenAI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.openai.chat.enabled (Removed and no longer valid) | Enable OpenAI chat model.  | true\n| spring.ai.model.chat | Enable OpenAI chat model.  | openai\n| spring.ai.openai.chat.base-url   | Optional overrides the `spring.ai.openai.base-url` to provide a chat specific url. Must be set to `http://localhost:12434/engines` |  -\n| spring.ai.openai.chat.api-key   | Optional overrides the spring.ai.openai.api-key to provide chat specific api-key |  -\n| spring.ai.openai.chat.options.model | The link:https://hub.docker.com/u/ai[LLM model] to use | -\n| spring.ai.openai.chat.options.temperature | The sampling temperature that controls the apparent creativity of generated completions. Higher values will make output more random while lower values will make results more focused and deterministic. It is not recommended to modify temperature and top_p for the same completions request as the interaction of these two settings is difficult to predict. | 0.8\n| spring.ai.openai.chat.options.frequencyPenalty | Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim. | 0.0f\n| spring.ai.openai.chat.options.maxTokens | The maximum number of tokens to generate in the chat completion. The total length of input tokens and generated tokens is limited by the model's context length.  | -\n| spring.ai.openai.chat.options.n | How many chat completion choices to generate for each input message. Note that you will be charged based on the number of generated tokens across all of the choices. Keep n as 1 to minimize costs. | 1\n| spring.ai.openai.chat.options.presencePenalty | Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics. | -\n| spring.ai.openai.chat.options.responseFormat | An object specifying the format that the model must output. Setting to `{ \"type\": \"json_object\" }` enables JSON mode, which guarantees the message the model generates is valid JSON.| -\n| spring.ai.openai.chat.options.seed | This feature is in Beta. If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result. | -\n| spring.ai.openai.chat.options.stop | Up to 4 sequences where the API will stop generating further tokens. | -\n| spring.ai.openai.chat.options.topP | An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both. | -\n| spring.ai.openai.chat.options.tools | A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for. | -\n| spring.ai.openai.chat.options.toolChoice | Controls which (if any) function is called by the model. none means the model will not call a function and instead generates a message. auto means the model can pick between generating a message or calling a function. Specifying a particular function via {\"type: \"function\", \"function\": {\"name\": \"my_function\"}} forces the model to call that function. none is the default when no functions are present. auto is the default if functions are present. | -\n| spring.ai.openai.chat.options.user | A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. | -\n| spring.ai.openai.chat.options.stream-usage | (For streaming only) Set to add an additional chunk with token usage statistics for the entire request. The `choices` field for this chunk is an empty array and all other chunks will also include a usage field, but with a null value. | false\n| spring.ai.openai.chat.options.tool-names | List of tools, identified by their names, to enable for function calling in a single prompt request. Tools with those names must exist in the ToolCallback registry. | -\n| spring.ai.openai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | -\n| spring.ai.openai.chat.options.internal-tool-execution-enabled | If false, the Spring AI will not handle the tool calls internally, but will proxy them to the client. Then it is the client's responsibility to handle the tool calls, dispatch them to the appropriate function, and return the results. If true (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support | true\n|====\n\nTIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding a request specific <<chat-options>> to the `Prompt` call.\n\n== Runtime Options [[chat-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions.java] provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.\n\nOn start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties.\n\nAt run-time you can override the default options by adding new, request specific, options to the `Prompt` call.\nFor example, to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        OpenAiChatOptions.builder()\n            .model(\"ai/gemma3:4B-F16\")\n        .build()\n    ));\n----\n\nTIP: In addition to the model specific https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n== Function Calling\n\nDocker Model Runner supports Tool/Function calling when selecting a model that supports it.\n\nYou can register custom Java functions with your ChatModel and have the provided model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions.\nThis is a powerful technique for connecting the LLM capabilities with external tools and APIs.\n\n=== Tool Example\n\nHere's a simple example of how to use Docker Model Runner function calling with Spring AI:\n\n[source,application.properties]\n----\nspring.ai.openai.api-key=test\nspring.ai.openai.base-url=http://localhost:12434/engines\nspring.ai.openai.chat.options.model=ai/gemma3:4B-F16\n----\n\n[source,java]\n----\n@SpringBootApplication\npublic class DockerModelRunnerLlmApplication {\n\n    public static void main(String[] args) {\n        SpringApplication.run(DockerModelRunnerLlmApplication.class, args);\n    }\n\n    @Bean\n    CommandLineRunner runner(ChatClient.Builder chatClientBuilder) {\n        return args -> {\n            var chatClient = chatClientBuilder.build();\n\n            var response = chatClient.prompt()\n                .user(\"What is the weather in Amsterdam and Paris?\")\n                .functions(\"weatherFunction\") // reference by bean name.\n                .call()\n                .content();\n\n            System.out.println(response);\n        };\n    }\n\n    @Bean\n    @Description(\"Get the weather in location\")\n    public Function<WeatherRequest, WeatherResponse> weatherFunction() {\n        return new MockWeatherService();\n    }\n\n    public static class MockWeatherService implements Function<WeatherRequest, WeatherResponse> {\n\n        public record WeatherRequest(String location, String unit) {}\n        public record WeatherResponse(double temp, String unit) {}\n\n        @Override\n        public WeatherResponse apply(WeatherRequest request) {\n            double temperature = request.location().contains(\"Amsterdam\") ? 20 : 25;\n            return new WeatherResponse(temperature, request.unit);\n        }\n    }\n}\n----\n\nIn this example, when the model needs weather information, it will automatically call the `weatherFunction` bean, which can then fetch real-time weather data.\nThe expected response is: \"The weather in Amsterdam is currently 20 degrees Celsius, and the weather in Paris is currently 25 degrees Celsius.\"\n\nRead more about OpenAI link:https://docs.spring.io/spring-ai/reference/api/chat/functions/openai-chat-functions.html[Function Calling].\n\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies.\n\nAdd a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model:\n\n[source,application.properties]\n----\nspring.ai.openai.api-key=test\nspring.ai.openai.base-url=http://localhost:12434/engines\nspring.ai.openai.chat.options.model=ai/gemma3:4B-F16\n\n# Docker Model Runner doesn't support embeddings, so we need to disable them.\nspring.ai.openai.embedding.enabled=false\n----\n\n\nHere is an example of a simple `@Controller` class that uses the chat model for text generation.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final OpenAiChatModel chatModel;\n\n    @Autowired\n    public ChatController(OpenAiChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return this.chatModel.stream(prompt);\n    }\n}\n----\n"

Only supported with Gemini Developer API (MLDev), not Vertex AI. See <<server-side-tool-invocations>>. | `false`\n| spring.ai.google.genai.chat.options.temperature | Controls the randomness of the output. Values can range over [0.0,1.0], inclusive. A value closer to 1.0 will produce responses that are more varied, while a value closer to 0.0 will typically result in less surprising responses from the generative. | -\n| spring.ai.google.genai.chat.options.top-k | The maximum number of tokens to consider when sampling. The generative uses combined Top-k and nucleus sampling. Top-k sampling considers the set of topK most probable tokens. | -\n| spring.ai.google.genai.chat.options.top-p | The maximum cumulative probability of tokens to consider when sampling.

Return temperature in 36°F or 36°C format.\")\npublic Function<Request, Response> weatherFunction() {\n    return new MockWeatherService();\n}\n\nString response = ChatClient.create(this.chatModel)\n        .prompt(\"What's the weather like in Boston?\")\n        .toolNames(\"weatherFunction\")\n        .inputType(Request.class)\n        .call()\n        .content();\n----\n\nFind more in xref:api/tools.adoc[Tools] documentation.\n\n== Server-Side Tool Invocations [[server-side-tool-invocations]]\n\nWhen Google Search or other server-side tools are enabled via `googleSearchRetrieval(true)`, the model executes these tools on the server. By default, these invocations are invisible to the client — you only see the final text response. Setting `includeServerSideToolInvocations(true)` makes the API include the server's tool calls and responses in the response content, allowing you to observe what the model searched for and what results it received.\n\n[IMPORTANT]\n====\nThis feature is only supported with the **Gemini Developer API** (MLDev / API key authentication), and models from Gemini 3.x and up. It is **not supported** on Vertex AI.\n====\n\n=== Configuration\n\nEnable via application properties:\n\n[source,application.properties]\n----\nspring.ai.google.genai.chat.options.google-search-retrieval=true\nspring.ai.google.genai.chat.options.include-server-side-tool-invocations=true\n----\n\nOr programmatically at runtime:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"What are the latest developments in quantum computing?\",\n        GoogleGenAiChatOptions.builder()\n            .model(\"gemini-2.0-flash\")\n            .googleSearchRetrieval(true)\n            .includeServerSideToolInvocations(true)\n            .build()\n    ));\n----\n\n=== Accessing Server-Side Tool Invocation Metadata\n\nWhen enabled, server-side tool invocations are available in the response message metadata under the `serverSideToolInvocations` key:\n\n[source,java]\n----\nChatResponse response = chatModel.call(prompt);\n\nMap<String, Object> metadata = response.getResult().getOutput().getMetadata();\n\n@SuppressWarnings(\"unchecked\")\nList<Map<String, Object>> invocations =\n    (List<Map<String, Object>>) metadata.get(\"serverSideToolInvocations\");\n\nif (invocations != null) {\n    for (Map<String, Object> invocation : invocations) {\n        String type = (String) invocation.get(\"type\");       // \"toolCall\" or \"toolResponse\"\n        String id = (String) invocation.get(\"id\");            // Unique invocation ID\n        String toolType = (String) invocation.get(\"toolType\"); // e.g., \"GOOGLE_SEARCH_WEB\"\n\n        if (\"toolCall\".equals(type)) {\n            Map<String, Object> args = (Map<String, Object>) invocation.get(\"args\");\n            // Inspect what the model searched for\n        } else if (\"toolResponse\".equals(type)) {\n            Map<String, Object> responseData = (Map<String, Object>) invocation.get(\"response\");\n            // Inspect what search results the model received\n        }\n    }\n}\n----\n\nEach entry in the list contains:\n\n[cols=\"1,3\", stripes=even]\n|====\n| Field | Description\n\n| `type` | Either `\"toolCall\"` (the model's invocation request) or `\"toolResponse\"` (the server's result)\n| `id` | Unique identifier linking a `toolCall` to its corresponding `toolResponse`\n| `toolType` | The type of server-side tool (e.g., `GOOGLE_SEARCH_WEB`, `GOOGLE_SEARCH_IMAGE`, `URL_CONTEXT`, `GOOGLE_MAPS`)\n| `args` | (toolCall only) The arguments passed to the tool\n| `response` | (toolResponse only) The results returned by the tool\n|====\n\n=== Combined with Function Calling\n\nServer-side tool invocations work alongside client-side function calling. You can enable both Google Search (server-side) and custom functions (client-side) in the same request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"What's the weather in San Francisco? Also search for the latest news about the city.\",\n        GoogleGenAiChatOptions.builder()\n            .model(\"gemini-2.0-flash\")\n            .googleSearchRetrieval(true)\n            .includeServerSideToolInvocations(true)\n            .toolCallbacks(List.of(\n                FunctionToolCallback.builder(\"get_current_weather\", new WeatherService())\n                    .description(\"Get the current weather in a given location\")\n                    .inputType(WeatherRequest.class)\n                    .build()))\n            .build()\n    ));\n\n// The response contains:\n// - Weather data from the client-side function call (executed locally)\n// - Google Search invocations visible in metadata (executed server-side)\n----\n\nNOTE: Server-side tool invocations are observational only — the client does not execute them. They are surfaced in metadata separately from client-side function calls to avoid interfering with the tool execution loop.\n\n== Thinking Configuration [[thinking-config]]\n\nGemini models support a \"thinking\" capability that allows the model to perform deeper reasoning before generating responses. This is controlled through the `ThinkingConfig` which includes three related options: `thinkingBudget`, `thinkingLevel`, and `includeThoughts`.\n\n=== Thinking Level\n\nThe `thinkingLevel` option controls the depth of reasoning tokens the model generates. This is available for models that support thinking (e.g., Gemini 3 Pro Preview).\n\n[cols=\"1,3\", stripes=even]\n|====\n| Value | Description\n\n| `LOW` | Minimal thinking. Use for simple queries where speed is preferred over deep analysis.\n| `HIGH` | Extensive thinking. Use for complex problems requiring deep analysis and step-by-step reasoning.\n| `THINKING_LEVEL_UNSPECIFIED` | The model uses its default behavior.\n|====\n\n==== Configuration via Properties\n\n[source,application.properties]\n----\nspring.ai.google.genai.chat.options.model=gemini-3-pro-preview\nspring.ai.google.genai.chat.options.thinking-level=HIGH\n----\n\n==== Programmatic Configuration\n\n[source,java]\n----\nimport org.springframework.ai.google.genai.common.GoogleGenAiThinkingLevel;\n\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Explain the theory of relativity in simple terms.\",\n        GoogleGenAiChatOptions.builder()\n            .model(\"gemini-3-pro-preview\")\n            .thinkingLevel(GoogleGenAiThinkingLevel.HIGH)\n            .build()\n    ));\n----\n\n=== Thinking Budget\n\nThe `thinkingBudget` option sets a token budget for the thinking process:\n\n- **Positive value**: Maximum number of tokens for thinking (e.g., `8192`)\n- **Zero (`0`)**: Disables thinking entirely\n- **Not set**: Model decides automatically based on query complexity\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Solve this complex math problem step by step.\",\n        GoogleGenAiChatOptions.builder()\n            .model(\"gemini-2.5-pro\")\n            .thinkingBudget(8192)\n            .build()\n    ));\n----\n\n=== Option Compatibility\n\n[IMPORTANT]\n====\n**`thinkingLevel` and `thinkingBudget` are mutually exclusive.** You cannot use both in the same request - doing so will result in an API error.\n\n* Use `thinkingLevel` (`LOW`, `HIGH`) for **Gemini 3 Pro** models\n* Use `thinkingBudget` (token count) for **Gemini 2.5** series models\n====\n\nYou can combine `includeThoughts` with either `thinkingLevel` or `thinkingBudget` (but not both):\n\n[source,java]\n----\n// For Gemini 3 Pro: use thinkingLevel + includeThoughts\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Analyze this complex scenario.\",\n        GoogleGenAiChatOptions.builder()\n            .model(\"gemini-3-pro-preview\")\n            .thinkingLevel(GoogleGenAiThinkingLevel.HIGH)\n            .includeThoughts(true)\n            .build()\n    ));\n\n// For Gemini 2.5: use thinkingBudget + includeThoughts\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Analyze this complex scenario.\",\n        GoogleGenAiChatOptions.builder()\n            .model(\"gemini-2.5-pro\")\n            .thinkingBudget(8192)\n            .includeThoughts(true)\n            .build()\n    ));\n----\n\n=== Model Support\n\nThe thinking configuration options are model-specific:\n\n[cols=\"2,1,1,2\", stripes=even]\n|====\n| Model | thinkingLevel | thinkingBudget | Notes\n\n| Gemini 3 Pro (Preview)\n| ✅ Supported\n| ⚠️ Backwards compatible only\n| Use `thinkingLevel`. Cannot disable thinking. Requires **global** endpoint.\n\n| Gemini 2.5 Pro\n| ❌ Not supported\n| ✅ Supported\n| Use `thinkingBudget`. Set to 0 to disable, -1 for dynamic.\n\n| Gemini 2.5 Flash\n| ❌ Not supported\n| ✅ Supported\n| Use `thinkingBudget`. Set to 0 to disable, -1 for dynamic.\n\n| Gemini 2.5 Flash-Lite\n| ❌ Not supported\n| ✅ Supported\n| Thinking disabled by default. Set `thinkingBudget` to enable.\n\n| Gemini 2.0 Flash\n| ❌ Not supported\n| ❌ Not supported\n| Thinking not available.\n|====\n\n[IMPORTANT]\n====\n* Using `thinkingLevel` with unsupported models (e.g., Gemini 2.5 or earlier) will result in an API error.\n* Gemini 3 Pro Preview is only available on **global** endpoints. Set `spring.ai.google.genai.location=global` or `GOOGLE_CLOUD_LOCATION=global`.\n* Check the https://ai.google.dev/gemini-api/docs/thinking[Google GenAI Thinking documentation] for the latest model capabilities.\n====\n\nNOTE: Enabling thinking features increases token usage and API costs. Use appropriately based on the complexity of your queries.\n\n== Thought Signatures [[thought-signatures]]\n\nGemini 3 Pro introduces thought signatures, which are opaque byte arrays that preserve the model's reasoning context during function calling. When `includeThoughts` is enabled, the model returns thought signatures that must be passed back within the **same turn** during the internal tool execution loop.\n\n=== When Thought Signatures Matter\n\n**IMPORTANT**: Thought signature validation only applies to the **current turn** - specifically during the internal tool execution loop when the model makes function calls (both parallel and sequential). The API does **not** validate thought signatures for previous turns in conversation history.\n\nPer https://ai.google.dev/gemini-api/docs/thought-signatures[Google's documentation]:\n\n* Validation is enforced for function calls within the current turn only\n* Previous turn signatures do not need to be preserved\n* Missing signatures in the current turn's function calls result in HTTP 400 errors for Gemini 3 Pro\n* For parallel function calls, only the first `functionCall` part carries the signature\n\nFor Gemini 2.5 Pro and earlier models, thought signatures are optional and the API is lenient.\n\n=== Configuration\n\nEnable thought signatures using configuration properties:\n\n[source,application.properties]\n----\nspring.ai.google.genai.chat.options.model=gemini-3-pro-preview\nspring.ai.google.genai.chat.options.include-thoughts=true\n----\n\nOr programmatically at runtime:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Your question here\",\n        GoogleGenAiChatOptions.builder()\n            .model(\"gemini-3-pro-preview\")\n            .includeThoughts(true)\n            .toolCallbacks(callbacks)\n            .build()\n    ));\n----\n\n=== Automatic Handling\n\nSpring AI automatically handles thought signatures during the internal tool execution loop. When `internalToolExecutionEnabled` is true (the default), Spring AI:\n\n1. **Extracts** thought signatures from model responses\n2. **Attaches** them to the correct `functionCall` parts when sending back function responses\n3. **Propagates** them correctly during function calls within a single turn (both parallel and sequential)\n\nYou don't need to manually manage thought signatures - Spring AI ensures they are properly attached to `functionCall` parts as required by the API specification.\n\n=== Example with Function Calling\n\n[source,java]\n----\n@Bean\n@Description(\"Get the weather in a location\")\npublic Function<WeatherRequest, WeatherResponse> weatherFunction() {\n    return new WeatherService();\n}\n\n// Enable includeThoughts for Gemini 3 Pro with function calling\nString response = ChatClient.create(this.chatModel)\n        .prompt(\"What's the weather like in Boston?\")\n        .options(GoogleGenAiChatOptions.builder()\n            .model(\"gemini-3-pro-preview\")\n            .includeThoughts(true)\n            .build())\n        .toolNames(\"weatherFunction\")\n        .call()\n        .content();\n----\n\n=== Manual Tool Execution Mode\n\nIf you set `internalToolExecutionEnabled=false` to manually control the tool execution loop, you must handle thought signatures yourself when using Gemini 3 Pro with `includeThoughts=true`.\n\n**Requirements for manual tool execution with thought signatures:**\n\n1. Extract thought signatures from the response metadata:\n+\n[source,java]\n----\nAssistantMessage assistantMessage = response.getResult().getOutput();\nMap<String, Object> metadata = assistantMessage.getMetadata();\nList<byte[]> thoughtSignatures = (List<byte[]>) metadata.get(\"thoughtSignatures\");\n----\n\n2. When sending back function responses, include the original `AssistantMessage` with its metadata intact in your message history. Spring AI will automatically attach the thought signatures to the correct `functionCall` parts.\n\n3. For Gemini 3 Pro, failing to preserve thought signatures during the current turn will result in HTTP 400 errors from the API.\n\nIMPORTANT: Only the current turn's function calls require thought signatures. When starting a new conversation turn (after completing a function calling round), you do not need to preserve the previous turn's signatures.\n\nNOTE: Enabling `includeThoughts` increases token usage as thought processes are included in responses. This impacts API costs but provides better reasoning transparency.\n\n== Multimodal\n\nMultimodality refers to a model's ability to simultaneously understand and process information from various (input) sources, including `text`, `pdf`, `images`, `audio`, and other data formats.\n\n=== Image, Audio, Video\nGoogle's Gemini AI models support this capability by comprehending and integrating text, code, audio, images, and video.\nFor more details, refer to the blog post https://blog.google/technology/ai/google-gemini-ai/#introducing-gemini[Introducing Gemini].\n\nSpring AI's `Message` interface supports multimodal AI models by introducing the Media type.\nThis type contains data and information about media attachments in messages, using Spring's `org.springframework.util.MimeType` and a `java.lang.Object` for the raw media data.\n\nBelow is a simple code example extracted from https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-google-genai/src/test/java/org/springframework/ai/google/genai/GoogleGenAiChatModelIT.java[GoogleGenAiChatModelIT.java], demonstrating the combination of user text with an image.\n\n\n[source,java]\n----\nbyte[] data = new ClassPathResource(\"/vertex-test.png\").getContentAsByteArray();\n\nvar userMessage = UserMessage.builder()\n\t\t\t.text(\"Explain what do you see o this picture?\")\n\t\t\t.media(List.of(new Media(MimeTypeUtils.IMAGE_PNG, data)))\n\t\t\t.build();\n\nChatResponse response = chatModel.call(new Prompt(List.of(this.userMessage)));\n----\n\n=== PDF\n\nGoogle GenAI provides support for PDF input types.\nUse the `application/pdf` media type to attach a PDF file to the message:\n\n[source,java]\n----\nvar pdfData = new ClassPathResource(\"/spring-ai-reference-overview.pdf\");\n\nvar userMessage = UserMessage.builder()\n\t\t\t.text(\"You are a very professional document summarization specialist. Please summarize the given document.\")\n\t\t\t.media(List.of(new Media(new MimeType(\"application\", \"pdf\"), pdfData)))\n\t\t\t.build();\n\nvar response = this.chatModel.call(new Prompt(List.of(userMessage)));\n----\n\n== Cached Content [[cached-content]]\n\nGoogle GenAI's https://ai.google.dev/gemini-api/docs/caching[Context Caching] allows you to cache large amounts of content (such as long documents, code repositories, or media) and reuse it across multiple requests. This significantly reduces API costs and improves response latency for repeated queries on the same content.\n\n=== Benefits\n\n- **Cost Reduction**: Cached tokens are billed at a much lower rate than regular input tokens (typically 75-90% cheaper)\n- **Improved Performance**: Reusing cached content reduces processing time for large contexts\n- **Consistency**: Same cached context ensures consistent responses across multiple requests\n\n=== Cache Requirements\n\n- Minimum cache size: 32,768 tokens (approximately 25,000 words)\n- Maximum cache duration: 1 hour by default (configurable via TTL)\n- Cached content must include either system instructions or conversation history\n\n=== Using Cached Content Service\n\nSpring AI provides `GoogleGenAiCachedContentService` for programmatic cache management. The service is automatically configured when using the Spring Boot auto-configuration.\n\n==== Creating Cached Content\n\n[source,java]\n----\n@Autowired\nprivate GoogleGenAiCachedContentService cachedContentService;\n\n// Create cached content with a large document\nString largeDocument = \"... your large context here (>32k tokens) ...\";\n\nCachedContentRequest request = CachedContentRequest.builder()\n    .model(\"gemini-2.0-flash\")\n    .contents(List.of(\n        Content.builder()\n            .role(\"user\")\n            .parts(List.of(Part.fromText(largeDocument)))\n            .build()\n    ))\n    .displayName(\"My Large Document Cache\")\n    .ttl(Duration.ofHours(1))\n    .build();\n\nGoogleGenAiCachedContent cachedContent = cachedContentService.create(request);\nString cacheName = cachedContent.getName(); // Save this for reuse\n----\n\n==== Using Cached Content in Chat Requests\n\nOnce you've created cached content, reference it in your chat requests:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Summarize the key points from the document\",\n        GoogleGenAiChatOptions.builder()\n            .useCachedContent(true)\n            .cachedContentName(cacheName) // Use the cached content name\n            .build()\n    ));\n----\n\nOr via configuration properties:\n\n[source,application.properties]\n----\nspring.ai.google.genai.chat.options.use-cached-content=true\nspring.ai.google.genai.chat.options.cached-content-name=cachedContent/your-cache-name\n----\n\n==== Managing Cached Content\n\nThe `GoogleGenAiCachedContentService` provides comprehensive cache management:\n\n[source,java]\n----\n// Retrieve cached content\nGoogleGenAiCachedContent content = cachedContentService.get(cacheName);\n\n// Update cache TTL\nCachedContentUpdateRequest updateRequest = CachedContentUpdateRequest.builder()\n    .ttl(Duration.ofHours(2))\n    .build();\nGoogleGenAiCachedContent updated = cachedContentService.update(cacheName, updateRequest);\n\n// List all cached content\nList<GoogleGenAiCachedContent> allCaches = cachedContentService.listAll();\n\n// Delete cached content\nboolean deleted = cachedContentService.delete(cacheName);\n\n// Extend cache TTL\nGoogleGenAiCachedContent extended = cachedContentService.extendTtl(cacheName, Duration.ofMinutes(30));\n\n// Cleanup expired caches\nint removedCount = cachedContentService.cleanupExpired();\n----\n\n==== Asynchronous Operations\n\nAll operations have asynchronous variants:\n\n[source,java]\n----\nCompletableFuture<GoogleGenAiCachedContent> futureCache =\n    cachedContentService.createAsync(request);\n\nCompletableFuture<GoogleGenAiCachedContent> futureGet =\n    cachedContentService.getAsync(cacheName);\n\nCompletableFuture<Boolean> futureDelete =\n    cachedContentService.deleteAsync(cacheName);\n----\n\n=== Auto-Caching\n\nSpring AI can automatically cache large prompts when they exceed a specified token threshold:\n\n[source,application.properties]\n----\n# Automatically cache prompts larger than 100,000 tokens\nspring.ai.google.genai.chat.options.auto-cache-threshold=100000\n# Set auto-cache TTL to 1 hour\nspring.ai.google.genai.chat.options.auto-cache-ttl=PT1H\n----\n\nOr programmatically:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        largePrompt,\n        GoogleGenAiChatOptions.builder()\n            .autoCacheThreshold(100000)\n            .autoCacheTtl(Duration.ofHours(1))\n            .build()\n    ));\n----\n\nNOTE: Auto-caching is useful for one-time large contexts. For repeated use of the same context, manually creating and referencing cached content is more efficient.\n\n=== Monitoring Cache Usage\n\nCached content includes usage metadata accessible via the service:\n\n[source,java]\n----\nGoogleGenAiCachedContent content = cachedContentService.get(cacheName);\n\n// Check if cache is expired\nboolean expired = content.isExpired();\n\n// Get remaining TTL\nDuration remaining = content.getRemainingTtl();\n\n// Get usage metadata\nCachedContentUsageMetadata metadata = content.getUsageMetadata();\nif (metadata != null) {\n    System.out.println(\"Total tokens: \" + metadata.totalTokenCount().orElse(0));\n}\n----\n\n=== Best Practices\n\n1. **Cache Lifetime**: Set appropriate TTL based on your use case. Shorter TTLs for frequently changing content, longer for static content.\n2. **Cache Naming**: Use descriptive display names to identify cached content easily.\n3. **Cleanup**: Periodically clean up expired caches to maintain organization.\n4. **Token Threshold**: Only cache content that exceeds the minimum threshold (32,768 tokens).\n5. **Cost Optimization**: Reuse cached content across multiple requests to maximize cost savings.\n\n=== Configuration Example\n\nComplete configuration example:\n\n[source,application.properties]\n----\n# Enable cached content service (enabled by default)\nspring.ai.google.genai.chat.enable-cached-content=true\n\n# Use a specific cached content\nspring.ai.google.genai.chat.options.use-cached-content=true\nspring.ai.google.genai.chat.options.cached-content-name=cachedContent/my-cache-123\n\n# Auto-caching configuration\nspring.ai.google.genai.chat.options.auto-cache-threshold=50000\nspring.ai.google.genai.chat.options.auto-cache-ttl=PT30M\n----\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-google-genai` to your pom (or gradle) dependencies.\n\nAdd a `application.properties` file, under the `src/main/resources` directory, to enable and configure the Google GenAI chat model:\n\n=== Using Gemini Developer API (API Key)\n\n[source,application.properties]\n----\nspring.ai.google.genai.api-key=YOUR_API_KEY\nspring.ai.google.genai.chat.options.model=gemini-2.0-flash\nspring.ai.google.genai.chat.options.temperature=0.5\n----\n\n=== Using Vertex AI\n\n[source,application.properties]\n----\nspring.ai.google.genai.project-id=PROJECT_ID\nspring.ai.google.genai.location=LOCATION\nspring.ai.google.genai.chat.options.model=gemini-2.0-flash\nspring.ai.google.genai.chat.options.temperature=0.5\n----\n\nTIP: Replace the `project-id` with your Google Cloud Project ID and `location` is Google Cloud Region\nlike `us-central1`, `europe-west1`, etc...\n\n[NOTE]\n====\nEach model has its own set of supported regions, you can find the list of supported regions in the model page.\n====\n\n\nThis will create a `GoogleGenAiChatModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the chat model for text generations.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final GoogleGenAiChatModel chatModel;\n\n    @Autowired\n    public ChatController(GoogleGenAiChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return this.chatModel.stream(prompt);\n    }\n}\n----\n\n== Manual Configuration\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-google-genai/src/main/java/org/springframework/ai/google/genai/GoogleGenAiChatModel.java[GoogleGenAiChatModel] implements the `ChatModel` and uses the `com.google.genai.Client` to connect to the Google GenAI service.\n\nAdd the `spring-ai-google-genai` dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-google-genai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-google-genai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNext, create a `GoogleGenAiChatModel` and use it for text generations:\n\n=== Using API Key\n\n[source,java]\n----\nClient genAiClient = Client.builder()\n    .apiKey(System.getenv(\"GOOGLE_API_KEY\"))\n    .build();\n\nvar chatModel = new GoogleGenAiChatModel(genAiClient,\n    GoogleGenAiChatOptions.builder()\n        .model(ChatModel.GEMINI_2_0_FLASH)\n        .temperature(0.4)\n    .build());\n\nChatResponse response = this.chatModel.call(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n----\n\n=== Using Vertex AI\n\n[source,java]\n----\nClient genAiClient = Client.builder()\n    .project(System.getenv(\"GOOGLE_CLOUD_PROJECT\"))\n    .location(System.getenv(\"GOOGLE_CLOUD_LOCATION\"))\n    .vertexAI(true)\n    .build();\n\nvar chatModel = new GoogleGenAiChatModel(genAiClient,\n    GoogleGenAiChatOptions.builder()\n        .model(ChatModel.GEMINI_2_0_FLASH)\n        .temperature(0.4)\n    .build());\n\nChatResponse response = this.chatModel.call(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n----\n\nThe `GoogleGenAiChatOptions` provides the configuration information for the chat requests.\nThe `GoogleGenAiChatOptions.Builder` is fluent options builder.\n\n== Migration from Vertex AI Gemini\n\nIf you were previously using the Vertex AI Gemini implementation (`spring-ai-vertex-ai-gemini`), which has been removed, migrate to Google GenAI:\n\nKey Differences:\n\n1. **SDK**: Google GenAI uses the new `com.google.genai.Client` instead of `com.google.cloud.vertexai.VertexAI`\n2.

Applicable only for chat models with function calling support | true\n|====\n\nTIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding a request specific <<chat-options>> to the `Prompt` call.\n\n== Runtime Options [[chat-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions.java] provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.\n\nOn start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties.\n\nAt run-time you can override the default options by adding new, request specific, options to the `Prompt` call.\nFor example to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        OpenAiChatOptions.builder()\n            .model(\"mixtral-8x7b-32768\")\n            .temperature(0.4)\n        .build()\n    ));\n----\n\nTIP: In addition to the model specific https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n== Function Calling\n\nGroq API endpoints support https://console.groq.com/docs/tool-use[tool/function calling] when selecting one of the Tool/Function supporting models.\n\nTIP: Check the Tool https://console.groq.com/docs/tool-use[Supported Models].\n\nimage::spring-ai-groq-functions-2.jpg[w=800,align=\"center\"]\n\nYou can register custom Java functions with your ChatModel and have the provided Groq model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions. \nThis is a powerful technique to connect the LLM capabilities with external tools and APIs. \n\n=== Tool Example\n\nHere's a simple example of how to use Groq function calling with Spring AI:\n\n[source,java]\n----    \n@SpringBootApplication\npublic class GroqApplication {\n\n    public static void main(String[] args) {\n        SpringApplication.run(GroqApplication.class, args);\n    }\n\n    @Bean\n    CommandLineRunner runner(ChatClient.Builder chatClientBuilder) {\n        return args -> {\n            var chatClient = chatClientBuilder.build();\n\n            var response = chatClient.prompt()\n                .user(\"What is the weather in Amsterdam and Paris?\")\n                .functions(\"weatherFunction\") // reference by bean name.\n                .call()\n                .content();\n\n            System.out.println(response);\n        };\n    }\n\n    @Bean\n    @Description(\"Get the weather in location\")\n    public Function<WeatherRequest, WeatherResponse> weatherFunction() {\n        return new MockWeatherService();\n    }\n\n    public static class MockWeatherService implements Function<WeatherRequest, WeatherResponse> {\n\n        public record WeatherRequest(String location, String unit) {}\n        public record WeatherResponse(double temp, String unit) {}\n\n        @Override\n        public WeatherResponse apply(WeatherRequest request) {\n            double temperature = request.location().contains(\"Amsterdam\") ? 20 : 25;\n            return new WeatherResponse(temperature, request.unit);\n        }\n    }\n}\n----\n    \nIn this example, when the model needs weather information, it will automatically call the `weatherFunction` bean, which can then fetch real-time weather data.\nThe expected response looks like this: \"The weather in Amsterdam is currently 20 degrees Celsius, and the weather in Paris is currently 25 degrees Celsius.\"\n    \nRead more about OpenAI link:https://docs.spring.io/spring-ai/reference/api/chat/functions/openai-chat-functions.html[Function Calling].\n\n\n\n== Multimodal\n\nNOTE: Currently the Groq API doesn't support media content.\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies.\n\nAdd a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model:\n\n[source,application.properties]\n----\nspring.ai.openai.api-key=<GROQ_API_KEY>\nspring.ai.openai.base-url=https://api.groq.com/openai\nspring.ai.openai.chat.options.model=llama3-70b-8192\nspring.ai.openai.chat.options.temperature=0.7\n----\n\nTIP: replace the `api-key` with your OpenAI credentials.\n\nThis will create a `OpenAiChatModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the chat model for text generations.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final OpenAiChatModel chatModel;\n\n    @Autowired\n    public ChatController(OpenAiChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return this.chatModel.stream(prompt);\n    }\n}\n----\n\n== Manual Configuration\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatModel.java[OpenAiChatModel] implements the `ChatModel` and `StreamingChatModel` and uses the <<low-level-api>> to connect to the OpenAI service.\n\nAdd the `spring-ai-openai` dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNext, create a `OpenAiChatModel` and use it for text generations:\n\n[source,java]\n----\nvar openAiApi = new OpenAiApi(\"https://api.groq.com/openai\", System.getenv(\"GROQ_API_KEY\"));\nvar openAiChatOptions = OpenAiChatOptions.builder()\n            .model(\"llama3-70b-8192\")\n            .temperature(0.4)\n            .maxTokens(200)\n        .build();\nvar chatModel = new OpenAiChatModel(this.openAiApi, this.openAiChatOptions);\n\n\nChatResponse response = this.chatModel.call(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n\n// Or with streaming responses\nFlux<ChatResponse> response = this.chatModel.stream(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n----\n\nThe `OpenAiChatOptions` provides the configuration information for the chat requests.\nThe `OpenAiChatOptions.Builder` is fluent options builder.\n"

If true (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support | true\n|====\n\nNOTE: You can override the common `spring.ai.minimax.base-url` and `spring.ai.minimax.api-key` for the `ChatModel` implementations.\nThe `spring.ai.minimax.chat.base-url` and `spring.ai.minimax.chat.api-key` properties if set take precedence over the common properties.\nThis is useful if you want to use different MiniMax accounts for different models and different model endpoints.\n\nTIP: All properties prefixed with `spring.ai.minimax.chat.options` can be overridden at runtime by adding a request specific <<chat-options>> to the `Prompt` call.\n\n== Runtime Options [[chat-options]]\n\nThe link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-minimax/src/main/java/org/springframework/ai/minimax/MiniMaxChatOptions.java[MiniMaxChatOptions.java] provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.\n\nOn start-up, the default options can be configured with the `MiniMaxChatModel(api, options)` constructor or the `spring.ai.minimax.chat.options.*` properties.\n\nAt run-time you can override the default options by adding new, request specific, options to the `Prompt` call.\nFor example to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        MiniMaxChatOptions.builder()\n            .model(MiniMaxApi.ChatModel.ABAB_6_5_S_Chat.getValue())\n            .temperature(0.5)\n        .build()\n    ));\n----\n\nTIP: In addition to the model specific link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-minimax/src/main/java/org/springframework/ai/minimax/MiniMaxChatOptions.java[MiniMaxChatOptions] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-minimax` to your pom (or gradle) dependencies.\n\nAdd a `application.properties` file, under the `src/main/resources` directory, to enable and configure the MiniMax chat model:\n\n[source,application.properties]\n----\nspring.ai.minimax.api-key=YOUR_API_KEY\nspring.ai.minimax.chat.options.model=abab6.5g-chat\nspring.ai.minimax.chat.options.temperature=0.7\n----\n\nTIP: replace the `api-key` with your MiniMax credentials.\n\nThis will create a `MiniMaxChatModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the chat model for text generations.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final MiniMaxChatModel chatModel;\n\n    @Autowired\n    public ChatController(MiniMaxChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue =

this.chatModel.call(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n\n// Or with streaming responses\nFlux<ChatResponse> streamResponse = this.chatModel.stream(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n----\n\nThe `MiniMaxChatOptions` provides the configuration information for the chat requests.\nThe `MiniMaxChatOptions.Builder` is fluent options builder.\n\n=== Low-level MiniMaxApi Client [[low-level-api]]\n\nThe

    "content": "= Mistral AI Chat\n\nSpring AI supports the various AI language models from Mistral AI. You can interact with Mistral AI language models and create a multilingual conversational assistant based on Mistral models.\n\nTIP: Mistral AI offers an OpenAI API-compatible endpoint as well.\nCheck the xref:_openai_api_compatibility[OpenAI API compatibility] section to learn how to use the xref:api/chat/openai-chat.adoc[Spring AI OpenAI] integration to talk to a Mistral endpoint.\n\n== Prerequisites\n\nYou will need to create an API with Mistral AI to access Mistral AI language models.\n\nCreate an account at https://auth.mistral.ai/ui/registration[Mistral AI registration page] and generate the token on the https://console.mistral.ai/api-keys/[API Keys page].\n\nThe Spring AI project defines a configuration property named `spring.ai.mistralai.api-key` that you should set to the value of the `API Key` obtained from console.mistral.ai.\n\nYou can set this configuration property in your `application.properties` file:\n\n[source,properties]\n----\nspring.ai.mistralai.api-key=<your-mistralai-api-key>\n----\n\nFor enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference a custom environment variable:\n\n[source,yaml]\n----\n# In application.yml\nspring:\n  ai:\n    mistralai:\n      api-key: ${MISTRALAI_API_KEY}\n----\n\n[source,bash]\n----\n# In your environment or .env file\nexport MISTRALAI_API_KEY=<your-mistralai-api-key>\n----\n\nYou can also set this configuration programmatically in your application code:\n\n[source,java]\n----\n// Retrieve API key from a secure source or environment variable\nString apiKey = System.getenv(\"MISTRALAI_API_KEY\");\n----\n\n=== Add Repositories and BOM\n\nSpring AI artifacts are published in Maven Central and Spring Snapshot repositories.\nRefer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system.\n\nTo help with dependency management, Spring AI provides a BOM (bill of materials) to ensure that a consistent version of Spring AI is used throughout the entire project. Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build system.\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the Mistral AI Chat Client.\nTo enable it add the following dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-mistral-ai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-mistral-ai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n=== Chat Properties\n\n==== Retry Properties\n\nThe prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the Mistral AI chat model.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.retry.max-attempts   | Maximum number of retry attempts. |  10\n| spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. |  2 sec.\n| spring.ai.retry.backoff.multiplier | Backoff interval multiplier. |  5\n| spring.ai.retry.backoff.max-interval | Maximum backoff duration. |  3 min.\n| spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false\n| spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty\n| spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty\n|====\n\n==== Connection Properties\n\nThe prefix `spring.ai.mistralai` is used as the property prefix that lets you connect to OpenAI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.mistralai.base-url   | The URL to connect to |  https://api.mistral.ai\n| spring.ai.mistralai.api-key    | The API Key           |  -\n|====\n\n==== Configuration Properties\n\n[NOTE]\n====\nEnabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`.\n\nTo enable, spring.ai.model.chat=mistral (It is enabled by default)\n\nTo disable, spring.ai.model.chat=none (or any value which doesn't match mistral)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix `spring.ai.mistralai.chat` is the property prefix that lets you configure the chat model implementation for Mistral AI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.mistralai.chat.enabled (Removed and no longer valid) | Enable Mistral AI chat model.  | true\n| spring.ai.model.chat | Enable Mistral AI chat model.  | mistral\n| spring.ai.mistralai.chat.base-url   | Optional override for the `spring.ai.mistralai.base-url` property to provide chat-specific URL. |  -\n| spring.ai.mistralai.chat.api-key   | Optional override for the `spring.ai.mistralai.api-key` to provide chat-specific API Key. |  -\n| spring.ai.mistralai.chat.options.model | This is the Mistral AI Chat model to use | `open-mistral-7b`, `open-mixtral-8x7b`, `open-mixtral-8x22b`, `mistral-small-latest`, `mistral-large-latest`\n| spring.ai.mistralai.chat.options.temperature | The sampling temperature to use that controls the apparent creativity of generated completions. Higher values will make output more random while lower values will make results more focused and deterministic. It is not recommended to modify `temperature` and `top_p` for the same completions request as the interaction of these two settings is difficult to predict. | 0.8\n| spring.ai.mistralai.chat.options.maxTokens | The maximum number of tokens to generate in the chat completion. The total length of input tokens and generated tokens is limited by the model's context length. | -\n| spring.ai.mistralai.chat.options.safePrompt | Indicates whether to inject a security prompt before all conversations. | false\n| spring.ai.mistralai.chat.options.randomSeed | This feature is in Beta. If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result. | -\n| spring.ai.mistralai.chat.options.stop | Stop generation if this token is detected. Or if one of these tokens is detected when providing an array. | -\n| spring.ai.mistralai.chat.options.topP | An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or `temperature` but not both. | -\n| spring.ai.mistralai.chat.options.responseFormat | An object specifying the format that the model must output. Setting to `{ \"type\": \"json_object\" }` enables JSON mode, which guarantees the message the model generates is valid JSON. Setting to `{ \"type\": \"json_schema\" }` with a supplied schema enables native structured outputs, which guarantees the model will match your supplied JSON schema. See the <<structured-output>> section for more details.| -\n| spring.ai.mistralai.chat.options.tools | A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for. | -\n| spring.ai.mistralai.chat.options.toolChoice | Controls which (if any) function is called by the model. `none` means the model will not call a function and instead generates a message. `auto` means the model can pick between generating a message or calling a function. Specifying a particular function via `{\"type: \"function\", \"function\": {\"name\": \"my_function\"}}` forces the model to call that function. `none` is the default when no functions are present. `auto` is the default if functions are present. | -\n| spring.ai.mistralai.chat.options.tool-names | List of tools, identified by their names, to enable for function calling in a single prompt request. Tools with those names must exist in the ToolCallback registry. | -\n| spring.ai.mistralai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | -\n| spring.ai.mistralai.chat.options.internal-tool-execution-enabled | If false, the Spring AI will not handle the tool calls internally, but will proxy them to the client. Then it is the client's responsibility to handle the tool calls, dispatch them to the appropriate function, and return the results. If true (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support | true\n|====\n\nNOTE: You can override the common `spring.ai.mistralai.base-url` and `spring.ai.mistralai.api-key` for the `ChatModel` and `EmbeddingModel` implementations.\nThe `spring.ai.mistralai.chat.base-url` and `spring.ai.mistralai.chat.api-key` properties, if set, take precedence over the common properties.\nThis is useful if you want to use different Mistral AI accounts for different models and different model endpoints.\n\nTIP: All properties prefixed with `spring.ai.mistralai.chat.options` can be overridden at runtime by adding request-specific <<chat-options>> to the `Prompt` call.\n\n== Runtime Options [[chat-options]]\n\nThe link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-mistral-ai/src/main/java/org/springframework/ai/mistralai/MistralAiChatOptions.java[MistralAiChatOptions.java] provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.\n\nOn start-up, the default options can be configured with the `MistralAiChatModel(api, options)` constructor or the `spring.ai.mistralai.chat.options.*` properties.\n\nAt run-time, you can override the default options by adding new, request-specific options to the `Prompt` call.\nFor example, to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        MistralAiChatOptions.builder()\n            .model(MistralAiApi.ChatModel.MISTRAL_LARGE.getValue())\n            .temperature(0.5)\n        .build()\n    ));\n----\n\nTIP: In addition to the model specific link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-mistral-ai/src/main/java/org/springframework/ai/mistralai/MistralAiChatOptions.java[MistralAiChatOptions] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n== Function Calling\n\nYou can register custom Java functions with the `MistralAiChatModel` and have the Mistral AI model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions.\nThis is a powerful technique to connect the LLM capabilities with external tools and APIs.\nRead more about xref:api/tools.adoc[Tool Calling].\n\n== Structured Output [[structured-output]]\n\nMistral AI supports native structured outputs through JSON Schema, ensuring the model generates responses that strictly conform to your specified structure.\nThis feature is available for Mistral Small and later models.\n\n=== Using ChatClient with Native Structured Output\n\nThe simplest way to use structured output is with the `ChatClient` high-level API and the `ENABLE_NATIVE_STRUCTURED_OUTPUT` advisor:\n\n[source,java]\n----\nrecord ActorsFilms(String actor, List<String> movies) {}\n\nActorsFilms actorsFilms = ChatClient.create(chatModel).prompt()\n    .advisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT)\n    .user(\"Generate the filmography of 5 movies for Tom Hanks.\")\n    .call()\n    .entity(ActorsFilms.class);\n----\n\nThis approach automatically:\n- Generates a JSON schema from your Java class\n- Configures the model to use native structured output\n- Parses the response into your specified type\n\n=== Using ResponseFormat Directly\n\nFor more control, you can use the `ResponseFormat` class with `MistralAiChatOptions`:\n\n[source,java]\n----\nrecord MovieRecommendation(String title, String director, int year, String plotSummary) {}\n\nvar options = MistralAiChatOptions.builder()\n    .model(MistralAiApi.ChatModel.MISTRAL_SMALL.getValue())\n    .responseFormat(ResponseFormat.jsonSchema(MovieRecommendation.class))\n    .build();\n\nChatResponse response = chatModel.call(\n    new Prompt(\"Recommend a classic science fiction movie.\", options));\n----\n\nThe `ResponseFormat` class provides several factory methods:\n\n* `ResponseFormat.text()` - Returns plain text output (default)\n* `ResponseFormat.jsonObject()` - Returns valid JSON (no schema enforcement)\n* `ResponseFormat.jsonSchema(Class<?>)` - Generates schema from a Java class\n* `ResponseFormat.jsonSchema(String)` - Uses a JSON schema string\n* `ResponseFormat.jsonSchema(Map)` - Uses a JSON schema map\n\n=== JSON Mode vs Structured Output\n\nMistral AI supports two JSON-related modes:\n\n* **JSON Mode** (`json_object`): Guarantees valid JSON output, but doesn't enforce a specific structure\n* **Structured Output** (`json_schema`): Guarantees output matching your JSON schema\n\n[source,java]\n----\n// JSON Mode - any valid JSON\nvar jsonMode = MistralAiChatOptions.builder()\n    .responseFormat(ResponseFormat.jsonObject())\n    .build();\n\n// Structured Output - specific schema enforced\nvar structuredOutput = MistralAiChatOptions.builder()\n    .responseFormat(ResponseFormat.jsonSchema(MyClass.class))\n    .build();\n----\n\nFor more information about structured outputs, see the xref:api/structured-output-converter.adoc[Structured Output Converter] documentation.\n\n== Multimodal\n\nMultimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats.\nMistral AI supports text and vision modalities.\n\n=== Vision\n\nMistral AI models that offer vision multimodal support include `pixtral-large-latest`.\nRefer to the link:https://docs.mistral.ai/capabilities/vision/[Vision] guide for more information.\n\nThe Mistral AI link:https://docs.mistral.ai/api/#tag/chat/operation/chat_completion_v1_chat_completions_post[User Message API] can incorporate a list of base64-encoded images or image urls with the message.\nSpring AI’s link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-client-chat/src/main/java/org/springframework/ai/chat/messages/Message.java[Message] interface facilitates multimodal AI models by introducing the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-commons/src/main/java/org/springframework/ai/content/Media.java[Media] type.\nThis type encompasses data and details regarding media attachments in messages, utilizing Spring’s `org.springframework.util.MimeType` and a `org.springframework.core.io.Resource` for the raw media data.\n\nBelow is a code example excerpted from `MistralAiChatModelIT.java`, illustrating the fusion of user text with an image.\n\n[source,java]\n----\nvar imageResource = new ClassPathResource(\"/multimodal.test.png\");\n\nvar userMessage = new UserMessage(\"Explain what do you see on this picture?\",\n        new Media(MimeTypeUtils.IMAGE_PNG, this.imageResource));\n\nChatResponse response = chatModel.call(new Prompt(this.userMessage,\n        ChatOptions.builder().model(MistralAiApi.ChatModel.PIXTRAL_LARGE.getValue()).build()));\n----\n\nor the image URL equivalent:\n\n[source,java]\n----\nvar userMessage = new UserMessage(\"Explain what do you see on this picture?\",\n        new Media(MimeTypeUtils.IMAGE_PNG,\n                URI.create(\"https://docs.spring.io/spring-ai/reference/_images/multimodal.test.png\")));\n\nChatResponse response = chatModel.call(new Prompt(this.userMessage,\n        ChatOptions.builder().model(MistralAiApi.ChatModel.PIXTRAL_LARGE.getValue()).build()));\n----\n\nTIP: You can pass multiple images as well.\n\nThe example shows a model taking as an input the `multimodal.test.png` image:\n\nimage::multimodal.test.png[Multimodal Test Image, 200, 200, align=\"left\"]\n\nalong with the text message \"Explain what do you see on this picture?\", and generating a response like this:\n\n----\nThis is an image of a fruit bowl with a simple design. The bowl is made of metal with curved wire edges that\ncreate an open structure, allowing the fruit to be visible from all angles. Inside the bowl, there are two\nyellow bananas resting on top of what appears to be a red apple. The bananas are slightly overripe, as\nindicated by the brown spots on their peels. The bowl has a metal ring at the top, likely to serve as a handle\nfor carrying. The bowl is placed on a flat surface with a neutral-colored background that provides a clear\nview of the fruit inside.\n----\n\n== OpenAI API Compatibility\n\nMistral is OpenAI API-compatible and you can use the xref:api/chat/openai-chat.adoc[Spring AI OpenAI] client to talk to Mistrial.\nFor this, you need to configure the OpenAI base URL to the Mistral AI platform: `spring.ai.openai.chat.base-url=https://api.mistral.ai`, and select a Mistral model: `spring.ai.openai.chat.options.model=mistral-small-latest` and set the Mistral AI API key: `spring.ai.openai.chat.api-key=<YOUR MISTRAL API KEY`.\n\nCheck the

If true (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support | true\n|====\n\nTIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding a request specific <<chat-options>> to the `Prompt` call.\n\n== Runtime Options [[chat-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions.java] provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.\n\nOn start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties.\n\nAt run-time you can override the default options by adding new, request specific, options to the `Prompt` call.\nFor example to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        OpenAiChatOptions.builder()\n            .model(\"mixtral-8x7b-32768\")\n            .temperature(0.4)\n        .build()\n    ));\n----\n\nTIP: In addition to the model specific https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n== Function Calling\n\nNVIDIA LLM API supports Tool/Function calling when selecting a model that supports it.\n\nimage::spring-ai-nvidia-function-calling.jpg[w=800,align=\"center\"]\n\nYou can register custom Java functions with your ChatModel and have the provided model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions. \nThis is a powerful technique to connect the LLM capabilities with external tools and APIs. \n\n=== Tool Example\n\nHere's a simple example of how to use NVIDIA LLM API function calling with Spring AI:\n\n[source,application.properties]\n----\nspring.ai.openai.api-key=${NVIDIA_API_KEY}\nspring.ai.openai.base-url=https://integrate.api.nvidia.com\nspring.ai.openai.chat.options.model=meta/llama-3.1-70b-instruct\nspring.ai.openai.chat.options.max-tokens=2048\n----\n\n[source,java]\n----    \n@SpringBootApplication\npublic class NvidiaLlmApplication {\n\n    public static void main(String[] args) {\n        SpringApplication.run(NvidiaLlmApplication.class, args);\n    }\n\n    @Bean\n    CommandLineRunner runner(ChatClient.Builder chatClientBuilder) {\n        return args -> {\n            var chatClient = chatClientBuilder.build();\n\n            var response = chatClient.prompt()\n                .user(\"What is the weather in Amsterdam and Paris?\")\n                .functions(\"weatherFunction\") // reference by bean name.\n                .call()\n                .content();\n\n            System.out.println(response);\n        };\n    }\n\n    @Bean\n    @Description(\"Get the weather in location\")\n    public Function<WeatherRequest, WeatherResponse> weatherFunction() {\n        return new MockWeatherService();\n    }\n\n    public static class MockWeatherService implements Function<WeatherRequest, WeatherResponse> {\n\n        public record WeatherRequest(String location, String unit) {}\n        public record WeatherResponse(double temp, String unit) {}\n\n        @Override\n        public WeatherResponse apply(WeatherRequest request) {\n            double temperature = request.location().contains(\"Amsterdam\") ? 20 : 25;\n            return new WeatherResponse(temperature, request.unit);\n        }\n    }\n}\n----\n    \nIn this example, when the model needs weather information, it will automatically call the `weatherFunction` bean, which can then fetch real-time weather data.\nThe expected response looks like this: \"The weather in Amsterdam is currently 20 degrees Celsius, and the weather in Paris is currently 25 degrees Celsius.\"\n    \nRead more about OpenAI link:https://docs.spring.io/spring-ai/reference/api/chat/functions/openai-chat-functions.html[Function Calling].\n\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies.\n\nAdd a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model:\n\n[source,application.properties]\n----\nspring.ai.openai.api-key=${NVIDIA_API_KEY}\nspring.ai.openai.base-url=https://integrate.api.nvidia.com\nspring.ai.openai.chat.options.model=meta/llama-3.1-70b-instruct\n\n# The NVIDIA LLM API doesn't support embeddings, so we need to disable it.\nspring.ai.openai.embedding.enabled=false\n\n# The NVIDIA LLM API requires this parameter to be set explicitly or server internal error will be thrown.\nspring.ai.openai.chat.options.max-tokens=2048\n----\n\nTIP: replace the `api-key` with your NVIDIA credentials.\n\nNOTE:  NVIDIA LLM API requires the `max-token` parameter to be explicitly set or server error will be thrown.\n\n\nHere is an example of a simple `@Controller` class that uses the chat model for text generations.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final OpenAiChatModel chatModel;\n\n    @Autowired\n    public ChatController(OpenAiChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return this.chatModel.stream(prompt);\n    }\n}\n----\n"

There are a few options, including the following:\n\n* link:https://ollama.com/download[Download and install Ollama] on your local machine.\n* Configure and xref:api/testcontainers.adoc[run Ollama via Testcontainers].\n* Bind to an Ollama instance via xref:api/cloud-bindings.adoc[Kubernetes Service Bindings].\n\nYou can pull the models you want to use in your application from the link:https://ollama.com/library[Ollama model library]:\n\n[source,shellscript]\n----\nollama pull <model-name>\n----\n\nYou can also pull any of the thousands, free, link:https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face Models]:\n\n[source,shellscript]\n----\nollama pull hf.co/<username>/<model-repository>\n----\n\nAlternatively, you can enable the option to download automatically any needed model: xref:auto-pulling-models[Auto-pulling Models].\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the Ollama chat integration.\nTo enable it add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files:\n\n[tabs]\n======\nMaven::\n+\n[source,xml]\n----\n<dependency>\n   <groupId>org.springframework.ai</groupId>\n   <artifactId>spring-ai-starter-model-ollama</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-ollama'\n}\n----\n======\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n=== Base Properties\n\nThe prefix `spring.ai.ollama` is the property prefix to configure the connection to Ollama.\n\n[cols=\"3,6,1\", stripes=even]\n|====\n| Property | Description | Default\n| spring.ai.ollama.base-url | Base URL where Ollama API server is running. | `+http://localhost:11434+`\n|====\n\nHere are the properties for initializing the Ollama integration and xref:auto-pulling-models[auto-pulling models].\n\n[cols=\"3,6,1\"]\n|====\n| Property | Description | Default\n| spring.ai.ollama.init.pull-model-strategy | Whether to pull models at startup-time and how. | `never`\n| spring.ai.ollama.init.timeout | How long to wait for a model to be pulled. | `5m`\n| spring.ai.ollama.init.max-retries | Maximum number of retries for the model pull operation. | `0`\n| spring.ai.ollama.init.chat.include | Include this type of models in the initialization task. | `true`\n| spring.ai.ollama.init.chat.additional-models | Additional models to initialize besides the ones configured via default properties. | `[]`\n|====\n\n=== Chat Properties\n\n[NOTE]\n====\nEnabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`.\n\nTo enable, spring.ai.model.chat=ollama (It is enabled by default)\n\nTo disable, spring.ai.model.chat=none (or any value which doesn't match ollama)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix `spring.ai.ollama.chat.options` is the property prefix that configures the Ollama chat model.\nIt includes the Ollama request (advanced) parameters such as the `model`, `keep-alive`, and `format` as well as the Ollama model `options` properties.\n\nHere are the advanced request parameter for the Ollama chat model:\n\n[cols=\"3,6,1\", stripes=even]\n|====\n| Property | Description | Default\n| spring.ai.ollama.chat.enabled (Removed and no longer valid)     | Enable Ollama chat model. | true\n| spring.ai.model.chat      | Enable Ollama chat model. | ollama\n| spring.ai.ollama.chat.options.model  | The name of the https://github.com/ollama/ollama?tab=readme-ov-file#model-library[supported model] to use. | mistral\n| spring.ai.ollama.chat.options.format  | The format to return a response in. Accepts either `\"json\"` (any JSON structure) or a JSON Schema object (enforced structure). See <<Structured Outputs>> for details. | -\n| spring.ai.ollama.chat.options.keep_alive  | Controls how long the model will stay loaded into memory following the request | 5m\n|====\n\nThe remaining `options` properties are based on the link:https://github.com/ollama/ollama/blob/main/docs/modelfile.md#valid-parameters-and-values[Ollama Valid Parameters and Values] and link:https://github.com/ollama/ollama/blob/main/api/types.go[Ollama Types]. The default values are based on the link:https://github.com/ollama/ollama/blob/b538dc3858014f94b099730a592751a5454cab0a/api/types.go#L364[Ollama Types Defaults].\n\n[cols=\"3,6,1\", stripes=even]\n|====\n| Property | Description | Default\n| spring.ai.ollama.chat.options.numa              | Whether to use NUMA.                                           | false\n| spring.ai.ollama.chat.options.num-ctx           | Sets the size of the context window used to generate the next token. | 2048\n| spring.ai.ollama.chat.options.num-batch         | Prompt processing maximum batch size. | 512\n| spring.ai.ollama.chat.options.num-gpu           | The number of layers to send to the GPU(s). On macOS it defaults to 1 to enable metal support, 0 to disable. 1 here indicates that NumGPU should be set dynamically | -1\n| spring.ai.ollama.chat.options.main-gpu          | When using multiple GPUs this option controls which GPU is used for small tensors for which the overhead of splitting the computation across all GPUs is not worthwhile. The GPU in question will use slightly more VRAM to store a scratch buffer for temporary results. | 0\n| spring.ai.ollama.chat.options.low-vram          | -                                                             | false\n| spring.ai.ollama.chat.options.f16-kv            | -                                                             | true\n| spring.ai.ollama.chat.options.logits-all        | Return logits for all the tokens, not just the last one. To enable completions to return logprobs, this must be true. | -\n| spring.ai.ollama.chat.options.vocab-only        | Load only the vocabulary, not the weights. | -\n| spring.ai.ollama.chat.options.use-mmap          | By default, models are mapped into memory, which allows the system to load only the necessary parts of the model as needed. However, if the model is larger than your total amount of RAM or if your system is low on available memory, using mmap might increase the risk of pageouts, negatively impacting performance. Disabling mmap results in slower load times but may reduce pageouts if you're not using mlock. Note that if the model is larger than the total amount of RAM, turning off mmap would prevent the model from loading at all. | null\n| spring.ai.ollama.chat.options.use-mlock         | Lock the model in memory, preventing it from being swapped out when memory-mapped. This can improve performance but trades away some of the advantages of memory-mapping by requiring more RAM to run and potentially slowing down load times as the model loads into RAM. | false\n| spring.ai.ollama.chat.options.num-thread        | Sets the number of threads to use during computation. By default, Ollama will detect this for optimal performance. It is recommended to set this value to the number of physical CPU cores your system has (as opposed to the logical number of cores). 0 = let the runtime decide | 0\n| spring.ai.ollama.chat.options.num-keep          | -                                                             | 4\n| spring.ai.ollama.chat.options.seed              | Sets the random number seed to use for generation. Setting this to a specific number will make the model generate the same text for the same prompt.  | -1\n| spring.ai.ollama.chat.options.num-predict       | Maximum number of tokens to predict when generating text. (-1 = infinite generation, -2 = fill context) | -1\n| spring.ai.ollama.chat.options.top-k             | Reduces the probability of generating nonsense. A higher value (e.g., 100) will give more diverse answers, while a lower value (e.g., 10) will be more conservative.  | 40\n| spring.ai.ollama.chat.options.top-p             | Works together with top-k. A higher value (e.g., 0.95) will lead to more diverse text, while a lower value (e.g., 0.5) will generate more focused and conservative text.  | 0.9\n| spring.ai.ollama.chat.options.min-p             | Alternative to the top_p, and aims to ensure a balance of quality and variety. The parameter p represents the minimum probability for a token to be considered, relative to the probability of the most likely token. For example, with p=0.05 and the most likely token having a probability of 0.9, logits with a value less than 0.045 are filtered out.  | 0.0\n| spring.ai.ollama.chat.options.tfs-z             | Tail-free sampling is used to reduce the impact of less probable tokens from the output. A higher value (e.g., 2.0) will reduce the impact more, while a value of 1.0 disables this setting. | 1.0\n| spring.ai.ollama.chat.options.typical-p         | -                                                             | 1.0\n| spring.ai.ollama.chat.options.repeat-last-n     | Sets how far back for the model to look back to prevent repetition. (Default: 64, 0 = disabled, -1 = num_ctx) | 64\n| spring.ai.ollama.chat.options.temperature       | The temperature of the model. Increasing the temperature will make the model answer more creatively. | 0.8\n| spring.ai.ollama.chat.options.repeat-penalty    | Sets how strongly to penalize repetitions. A higher value (e.g., 1.5) will penalize repetitions more strongly, while a lower value (e.g., 0.9) will be more lenient. | 1.1\n| spring.ai.ollama.chat.options.presence-penalty  | -                                                             | 0.0\n| spring.ai.ollama.chat.options.frequency-penalty | -                                                             | 0.0\n| spring.ai.ollama.chat.options.mirostat          | Enable Mirostat sampling for controlling perplexity. (default: 0, 0 = disabled, 1 = Mirostat, 2 = Mirostat 2.0) | 0\n| spring.ai.ollama.chat.options.mirostat-tau      | Controls the balance between coherence and diversity of the output. A lower value will result in more focused and coherent text. | 5.0\n| spring.ai.ollama.chat.options.mirostat-eta      | Influences how quickly the algorithm responds to feedback from the generated text. A lower learning rate will result in slower adjustments, while a higher learning rate will make the algorithm more responsive. | 0.1\n| spring.ai.ollama.chat.options.penalize-newline  | -                                                             | true\n| spring.ai.ollama.chat.options.stop              | Sets the stop sequences to use. When this pattern is encountered the LLM will stop generating text and return. Multiple stop patterns may be set by specifying multiple separate stop parameters in a modelfile. | -\n| spring.ai.ollama.chat.options.tool-names         | List of tools, identified by their names, to enable for function calling in a single prompt request. Tools with those names must exist in the ToolCallback registry. | -\n| spring.ai.ollama.chat.options.tool-callbacks     | Tool Callbacks to register with the ChatModel. | -\n| spring.ai.ollama.chat.options.internal-tool-execution-enabled | If false, the Spring AI will not handle the tool calls internally, but will proxy them to the client. Then it is the client's responsibility to handle the tool calls, dispatch them to the appropriate function, and return the results. If true (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support | true\n|====\n\nTIP: All properties prefixed with `spring.ai.ollama.chat.options` can be overridden at runtime by adding request-specific <<chat-options>> to the `Prompt` call.\n\n== Runtime Options [[chat-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-ollama/src/main/java/org/springframework/ai/ollama/api/OllamaChatOptions.java[OllamaChatOptions.java] class provides model configurations, such as the model to use, the temperature, thinking mode, etc.\n\nIMPORTANT: The `OllamaOptions` class has been deprecated. Use `OllamaChatOptions` for chat models and `OllamaEmbeddingOptions` for embedding models instead. The new classes provide type-safe, model-specific configuration options.\n\nOn start-up, the default options can be configured with the `OllamaChatModel(api, options)` constructor or the `spring.ai.ollama.chat.options.*` properties.\n\nAt run-time, you can override the default options by adding new, request-specific options to the `Prompt` call.\nFor example, to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        OllamaChatOptions.builder()\n            .model(OllamaModel.LLAMA3_1)\n            .temperature(0.4)\n            .build()\n    ));\n----\n\nTIP: In addition to the model specific link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-ollama/src/main/java/org/springframework/ai/ollama/api/OllamaChatOptions.java[OllamaChatOptions] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n[[auto-pulling-models]]\n== Auto-pulling Models\n\nSpring AI Ollama can automatically pull models when they are not available in your Ollama instance.\nThis feature is particularly useful for development and testing as well as for deploying your applications to new environments.\n\nTIP: You can also pull, by name, any of the thousands, free, link:https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face Models].\n\nThere are three strategies for pulling models:\n\n* `always` (defined in `PullModelStrategy.ALWAYS`): Always pull the model, even if it's already available. Useful to ensure you're using the latest version of the model.\n* `when_missing` (defined in `PullModelStrategy.WHEN_MISSING`): Only pull the model if it's not already available. This may result in using an older version of the model.\n* `never` (defined in `PullModelStrategy.NEVER`): Never pull the model automatically.\n\nCAUTION: Due to potential delays while downloading models, automatic pulling is not recommended for production environments. Instead, consider assessing and pre-downloading the necessary models in advance.\n\nAll models defined via configuration properties and default options can be automatically pulled at startup time.\nYou can configure the pull strategy, timeout, and maximum number of retries using configuration properties:\n\n[source,yaml]\n----\nspring:\n  ai:\n    ollama:\n      init:\n        pull-model-strategy: always\n        timeout: 60s\n        max-retries: 1\n----\n\nCAUTION: The application will not complete its initialization until all specified models are available in Ollama. Depending on the model size and internet connection speed, this may significantly slow down your application's startup time.\n\nYou can initialize additional models at startup, which is useful for models used dynamically at runtime:\n\n[source,yaml]\n----\nspring:\n  ai:\n    ollama:\n      init:\n        pull-model-strategy: always\n        chat:\n          additional-models:\n            - llama3.2\n            - qwen2.5\n----\n\nIf you want to apply the pulling strategy only to specific types of models, you can exclude chat models from the initialization task:\n\n[source,yaml]\n----\nspring:\n  ai:\n    ollama:\n      init:\n        pull-model-strategy: always\n        chat:\n          include: false\n----\n\nThis configuration will apply the pulling strategy to all models except chat models.\n\n== Function Calling\n\nYou can register custom Java functions with the `OllamaChatModel` and have the Ollama model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions.\nThis is a powerful technique to connect the LLM capabilities with external tools and APIs.\nRead more about xref:api/tools.adoc[Tool Calling].\n\nTIP: You need Ollama 0.2.8 or newer to use the functional calling capabilities and Ollama 0.4.6 or newer to use them in streaming mode.\n\n== Thinking Mode (Reasoning)\n\nOllama supports thinking mode for reasoning models that can emit their internal reasoning process before providing a final answer. This feature is available for models like Qwen3, DeepSeek-v3.1, DeepSeek R1, and GPT-OSS.\n\nTIP: Thinking mode helps you understand the model's reasoning process and can improve response quality for complex problems.\n\nIMPORTANT: *Default Behavior (Ollama 0.12+)*: Thinking-capable models (such as `qwen3:*-thinking`, `deepseek-r1`, `deepseek-v3.1`) *auto-enable thinking by default* when the think option is not explicitly set. Standard models (such as `qwen2.5:*`, `llama3.2`) do not enable thinking by default. To explicitly control this behavior, use `.enableThinking()` or `.disableThinking()`.\n\n=== Enabling Thinking Mode\n\nMost models (Qwen3, DeepSeek-v3.1, DeepSeek R1) support simple boolean enable/disable:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"How many letter 'r' are in the word 'strawberry'?\",\n        OllamaChatOptions.builder()\n            .model(\"qwen3\")\n            .enableThinking()\n            .build()\n    ));\n\n// Access the thinking process\nString thinking = response.getResult().getMetadata().get(\"thinking\");\nString answer = response.getResult().getOutput().getText();\n----\n\nYou can also disable thinking explicitly:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"What is 2+2?\",\n        OllamaChatOptions.builder()\n            .model(\"deepseek-r1\")\n            .disableThinking()\n            .build()\n    ));\n----\n\n=== Thinking Levels (GPT-OSS Only)\n\nThe GPT-OSS model requires explicit thinking levels instead of boolean values:\n\n[source,java]\n----\n// Low thinking level\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate a short headline\",\n        OllamaChatOptions.builder()\n            .model(\"gpt-oss\")\n            .thinkLow()\n            .build()\n    ));\n\n// Medium thinking level\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Analyze this dataset\",\n        OllamaChatOptions.builder()\n            .model(\"gpt-oss\")\n            .thinkMedium()\n            .build()\n    ));\n\n// High thinking level\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Solve this complex problem\",\n        OllamaChatOptions.builder()\n            .model(\"gpt-oss\")\n            .thinkHigh()\n            .build()\n    ));\n----\n\n=== Accessing Thinking Content\n\nThe thinking content is available in the response metadata:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Calculate 17 × 23\",\n        OllamaChatOptions.builder()\n            .model(\"deepseek-r1\")\n            .enableThinking()\n            .build()\n    ));\n\n// Get the reasoning process\nString thinking = response.getResult().getMetadata().get(\"thinking\");\nSystem.out.println(\"Reasoning: \" + thinking);\n// Output: \"17 × 20 = 340, 17 × 3 = 51, 340 + 51 = 391\"\n\n// Get the final answer\nString answer = response.getResult().getOutput().getText();\nSystem.out.println(\"Answer: \" + answer);\n// Output: \"The answer is 391\"\n----\n\n=== Streaming with Thinking\n\nThinking mode works with streaming responses as well:\n\n[source,java]\n----\nFlux<ChatResponse> stream = chatModel.stream(\n    new Prompt(\n        \"Explain quantum entanglement\",\n        OllamaChatOptions.builder()\n            .model(\"qwen3\")\n            .enableThinking()\n            .build()\n    ));\n\nstream.subscribe(response -> {\n    String thinking = response.getResult().getMetadata().get(\"thinking\");\n    String content = response.getResult().getOutput().getText();\n\n    if (thinking != null && !thinking.isEmpty()) {\n        System.out.println(\"[Thinking] \" + thinking);\n    }\n    if (content != null && !content.isEmpty()) {\n        System.out.println(\"[Response] \" + content);\n    }\n});\n----\n\nNOTE: When thinking is disabled or not set, the `thinking` metadata field will be null or empty.\n\n== Multimodal\n\nMultimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats.\n\nSome of the models available in Ollama with multimodality support are https://ollama.com/library/llava[LLaVA] and https://ollama.com/library/bakllava[BakLLaVA] (see the link:https://ollama.com/search?c=vision[full list]).\nFor further details, refer to the link:https://llava-vl.github.io/[LLaVA: Large Language and Vision Assistant].\n\nThe Ollama link:https://github.com/ollama/ollama/blob/main/docs/api.md#parameters-1[Message API] provides an \"images\" parameter to incorporate a list of base64-encoded images with the message.\n\nSpring AI’s link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/messages/Message.java[Message] interface facilitates multimodal AI models by introducing the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-commons/src/main/java/org/springframework/ai/content/Media.java[Media] type.\nThis type encompasses data and details regarding media attachments in messages, utilizing Spring’s `org.springframework.util.MimeType` and a `org.springframework.core.io.Resource` for the raw media data.\n\nBelow is a straightforward code example excerpted from link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-ollama/src/test/java/org/springframework/ai/ollama/OllamaChatModelMultimodalIT.java[OllamaChatModelMultimodalIT.java], illustrating the fusion of user text with an image.\n\n[source,java]\n----\nvar imageResource = new ClassPathResource(\"/multimodal.test.png\");\n\nvar userMessage = new UserMessage(\"Explain what do you see on this picture?\",\n        new Media(MimeTypeUtils.IMAGE_PNG, this.imageResource));\n\nChatResponse response = chatModel.call(new Prompt(this.userMessage,\n        OllamaChatOptions.builder().model(OllamaModel.LLAVA)).build());\n----\n\nThe example shows a model taking as an input the `multimodal.test.png` image:\n\nimage::multimodal.test.png[Multimodal Test Image, 200, 200, align=\"left\"]\n\nalong with the text message \"Explain what do you see on this picture?\", and generating a response like this:\n\n----\nThe image shows a small metal basket filled with ripe bananas and red apples. The basket is placed on a surface,\nwhich appears to be a table or countertop, as there's a hint of what seems like a kitchen cabinet or drawer in\nthe background. There's also a gold-colored ring visible behind the basket, which could indicate that this\nphoto was taken in an area with metallic decorations or fixtures. The overall setting suggests a home environment\nwhere fruits are being displayed, possibly for convenience or aesthetic purposes.\n----\n\n== Structured Outputs\n\nOllama provides custom https://ollama.com/blog/structured-outputs[Structured Outputs] APIs that ensure your model generates responses conforming strictly to your provided `JSON Schema`.\nIn addition to the existing Spring AI model-agnostic xref::api/structured-output-converter.adoc[Structured Output Converter], these APIs offer enhanced control and precision.\n\n=== Two Modes for Structured Output\n\nOllama supports two different modes for structured output through the `format` parameter:\n\n1. **Simple \"json\" Format**: Instructs Ollama to return any valid JSON structure (unpredictable schema)\n2. **JSON Schema Format**: Instructs Ollama to return JSON conforming to a specific schema (predictable structure)\n\n==== Simple \"json\" Format\n\nUse this when you want JSON output but don't need a specific structure:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"List 3 countries in Europe\",\n        OllamaChatOptions.builder()\n            .model(\"llama3.2\")\n            .format(\"json\")  // Any valid JSON\n            .build()\n    ));\n----\n\nThe model can return any JSON structure it chooses:\n\n[source,json]\n----\n[\"France\", \"Germany\", \"Italy\"]\n// or\n{\"countries\": [\"France\", \"Germany\", \"Italy\"]}\n// or\n{\"data\": {\"european_countries\": [\"France\", \"Germany\", \"Italy\"]}}\n----\n\n==== JSON Schema Format (Recommended for Production)\n\nUse this when you need a guaranteed, predictable structure:\n\n[source,java]\n----\nString jsonSchema = \"\"\"\n{\n    \"type\": \"object\",\n    \"properties\": {\n        \"countries\": {\n            \"type\": \"array\",\n            \"items\": { \"type\": \"string\" }\n        }\n    },\n    \"required\": [\"countries\"]\n}\n\"\"\";\n\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"List 3 countries in Europe\",\n        OllamaChatOptions.builder()\n            .model(\"llama3.2\")\n            .outputSchema(jsonSchema)  // Enforced schema\n            .build()\n    ));\n----\n\nThe model **must** return this exact structure:\n\n[source,json]\n----\n{\"countries\": [\"France\", \"Germany\", \"Italy\"]}\n----\n\n=== Configuration\n\nSpring AI allows you to configure your response format programmatically using the `OllamaChatOptions` builder.\n\n==== Using the Chat Options Builder with JSON Schema\n\nYou can set the response format programmatically with the `OllamaChatOptions` builder:\n\n[source,java]\n----\nString jsonSchema = \"\"\"\n        {\n            \"type\": \"object\",\n            \"properties\": {\n                \"steps\": {\n                    \"type\": \"array\",\n                    \"items\": {\n                        \"type\": \"object\",\n                        \"properties\": {\n                            \"explanation\": { \"type\": \"string\" },\n                            \"output\": { \"type\": \"string\" }\n                        },\n                        \"required\": [\"explanation\", \"output\"],\n                        \"additionalProperties\": false\n                    }\n                },\n                \"final_answer\": { \"type\": \"string\" }\n            },\n            \"required\": [\"steps\", \"final_answer\"],\n            \"additionalProperties\": false\n        }\n        \"\"\";\n\nPrompt prompt = new Prompt(\"how can I solve 8x + 7 = -23\",\n        OllamaChatOptions.builder()\n            .model(OllamaModel.LLAMA3_2.getName())\n            .outputSchema(jsonSchema)  // Pass JSON Schema as string\n            .build());\n\nChatResponse response = this.ollamaChatModel.call(this.prompt);\n----\n\n==== Integrating with BeanOutputConverter Utilities\n\nYou can leverage existing xref::api/structured-output-converter.adoc#_bean_output_converter[BeanOutputConverter] utilities to automatically generate the JSON Schema from your domain objects and later convert the structured response into domain-specific instances:\n\n[source,java]\n----\nrecord MathReasoning(\n    @JsonProperty(required = true, value = \"steps\") Steps steps,\n    @JsonProperty(required = true, value = \"final_answer\") String finalAnswer) {\n\n    record Steps(\n        @JsonProperty(required = true, value = \"items\") Items[] items) {\n\n        record Items(\n            @JsonProperty(required = true, value = \"explanation\") String explanation,\n            @JsonProperty(required = true, value = \"output\") String output) {\n        }\n    }\n}\n\nvar outputConverter = new BeanOutputConverter<>(MathReasoning.class);\n\nPrompt prompt = new Prompt(\"how can I solve 8x + 7 = -23\",\n        OllamaChatOptions.builder()\n            .model(OllamaModel.LLAMA3_2.getName())\n            .outputSchema(outputConverter.getJsonSchema())  // Get JSON Schema as string\n            .build());\n\nChatResponse response = this.ollamaChatModel.call(this.prompt);\nString content = this.response.getResult().getOutput().getText();\n\nMathReasoning mathReasoning = this.outputConverter.convert(this.content);\n----\n\nNOTE: Ensure you use the `@JsonProperty(required = true,...)`  annotation for generating a schema that accurately marks fields as `required`.\nAlthough this is optional for JSON Schema, it's recommended for the structured response to function correctly.\n\n=== API Methods: `.format()` vs `.outputSchema()`\n\nSpring AI provides two methods for configuring structured output:\n\n[cols=\"2,3,3\", options=\"header\"]\n|====\n| Method | Use Case | Example\n\n| `.format(\"json\")`\n| Simple JSON mode - any structure\n| `.format(\"json\")`\n\n| `.outputSchema(jsonSchemaString)`\n| JSON Schema mode - enforced structure\n| `.outputSchema(\"{\\\"type\\\":\\\"object\\\",...}\")`\n\n| `.format(mapObject)`\n| JSON Schema mode - alternative API\n| `.format(new ObjectMapper().readValue(schema, Map.class))`\n|====\n\nTIP: For most use cases, use `.outputSchema(jsonSchemaString)` for JSON Schema validation or `.format(\"json\")` for simple JSON output.\nThe `.format(Map)` approach is also supported but requires manual JSON parsing.\n\n== OpenAI API Compatibility\n\nOllama is OpenAI API-compatible and you can use the xref:api/chat/openai-chat.adoc[Spring AI OpenAI] client to talk to Ollama and use tools.\nFor this, you need to configure the OpenAI base URL to your Ollama instance: `spring.ai.openai.chat.base-url=http://localhost:11434` and select one of the provided Ollama models: `spring.ai.openai.chat.options.model=mistral`.\n\nTIP: When using the OpenAI client with Ollama, you can pass Ollama-specific parameters (like `top_k`, `repeat_penalty`, `num_predict`) using the xref:api/chat/openai-chat.adoc#openai-compatible-servers[`extraBody` option].\nThis allows you to leverage Ollama's full capabilities while using the OpenAI client.\n\nimage::spring-ai-ollama-over-openai.jpg[Ollama OpenAI API compatibility, 800, 600, align=\"center\"]\n\n=== Reasoning Content via OpenAI Compatibility\n\nOllama's OpenAI-compatible endpoint supports the `reasoning_content` field for thinking-capable models (such as `qwen3:*-thinking`, `deepseek-r1`, `deepseek-v3.1`).\nWhen using the Spring AI OpenAI client with Ollama, the model's reasoning process is automatically captured and made available through the response metadata.\n\nNOTE: This is an alternative to using Ollama's native thinking mode API (documented in <<Thinking Mode (Reasoning)>> above).\nBoth approaches work with Ollama's thinking models, but the OpenAI-compatible endpoint uses the `reasoning_content` field name instead of `thinking`.\n\nHere's an example of accessing reasoning content from Ollama through the OpenAI client:\n\n[source,java]\n----\n// Configure Spring AI OpenAI client to point to Ollama\n@Configuration\nclass OllamaConfig {\n    @Bean\n    OpenAiChatModel ollamaChatModel() {\n        var openAiApi = new OpenAiApi(\"http://localhost:11434\", \"ollama\");\n        return new OpenAiChatModel(openAiApi,\n            OpenAiChatOptions.builder()\n                .model(\"deepseek-r1\")  // or qwen3, deepseek-v3.1, etc.\n                .build());\n    }\n}\n\n// Use the model with thinking-capable models\nChatResponse response = chatModel.call(\n    new Prompt(\"How many letter 'r' are in the word 'strawberry'?\"));\n\n// Access the reasoning process from metadata\nString reasoning = response.getResult().getMetadata().get(\"reasoningContent\");\nif (reasoning != null && !reasoning.isEmpty()) {\n    System.out.println(\"Model's reasoning process:\");\n    System.out.println(reasoning);\n}\n\n// Get the final answer\nString answer = response.getResult().getOutput().getText();\nSystem.out.println(\"Answer: \" + answer);\n----\n\nTIP: Thinking-capable models in Ollama (0.12+) automatically enable thinking mode when accessed through the OpenAI-compatible endpoint.\nThe reasoning content is captured automatically without requiring additional configuration.\n\nCheck the link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/chat/proxy/OllamaWithOpenAiChatModelIT.java[OllamaWithOpenAiChatModelIT.java] tests for examples of using Ollama over Spring AI OpenAI.\n\n== HuggingFace Models\n\nOllama can access, out of the box, all https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face ] Chat Models.\nYou can pull any of these models by name: `ollama pull hf.co/<username>/<model-repository>` or configure the auto-pulling strategy: xref:auto-pulling-models[Auto-pulling Models]:\n\n[source]\n----\nspring.ai.ollama.chat.options.model=hf.co/bartowski/gemma-2-2b-it-GGUF\nspring.ai.ollama.init.pull-model-strategy=always\n----\n\n- `spring.ai.ollama.chat.options.model`: Specifies the https://huggingface.co/models?library=gguf&sort=trending[Hugging Face GGUF model] to use. \n- `spring.ai.ollama.init.pull-model-strategy=always`: (optional) Enables automatic model pulling at startup time. \nFor production, you should pre-download the models to avoid delays: `ollama pull hf.co/bartowski/gemma-2-2b-it-GGUF`.\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-ollama` to your pom (or gradle) dependencies.\n\nAdd a `application.yaml` file, under the `src/main/resources` directory, to enable and configure the Ollama chat model:\n\n[source,yaml]\n----\nspring:\n  ai:\n    ollama:\n      base-url: http://localhost:11434\n      chat:\n        options:\n          model: mistral\n          temperature: 0.7\n----\n\nTIP: Replace the `base-url` with your Ollama server URL.\n\nThis will create an `OllamaChatModel` implementation that you can inject into your classes.\nHere is an example of a simple `@RestController` class that uses the chat model for text generations.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final OllamaChatModel chatModel;\n\n    @Autowired\n    public ChatController(OllamaChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map<String,String> generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return this.chatModel.stream(prompt);\n    }\n\n}\n----\n\n== Manual Configuration\n\nIf you don't want to use the Spring Boot auto-configuration, you can manually configure the `OllamaChatModel` in your application.\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-ollama/src/main/java/org/springframework/ai/ollama/OllamaChatModel.java[OllamaChatModel] implements the `ChatModel` and `StreamingChatModel` and uses the <<low-level-api>> to connect to the Ollama service.\n\nTo use it, add the `spring-ai-ollama` dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files:\n\n[tabs]\n======\nMaven::\n+\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-ollama</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-ollama'\n}\n----\n======\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nTIP: The `spring-ai-ollama` dependency provides access also to the `OllamaEmbeddingModel`.\nFor more information about the `OllamaEmbeddingModel` refer to the link:../embeddings/ollama-embeddings.html[Ollama Embedding Model] section.\n\nNext, create an `OllamaChatModel` instance and use it to send requests for text generation:\n\n[source,java]\n----\nvar ollamaApi = OllamaApi.builder().build();\n\nvar chatModel = OllamaChatModel.builder()\n                    .ollamaApi(ollamaApi)\n                    .defaultOptions(\n                        OllamaChatOptions.builder()\n                            .model(OllamaModel.MISTRAL)\n                            .temperature(0.9)\n                            .build())\n                    .build();\n\nChatResponse response = this.chatModel.call(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n\n// Or with streaming responses\nFlux<ChatResponse> response = this.chatModel.stream(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n----\n\nThe `OllamaChatOptions` provides the configuration information for all chat requests.\n\n== Low-level OllamaApi Client [[low-level-api]]\n\nThe link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-ollama/src/main/java/org/springframework/ai/ollama/api/OllamaApi.java[OllamaApi] provides a lightweight Java client for the Ollama Chat Completion API link:https://github.com/ollama/ollama/blob/main/docs/api.md#generate-a-chat-completion[Ollama Chat Completion API].\n\nThe following class diagram illustrates the `OllamaApi` chat interfaces and building blocks:\n\nimage::ollama-chat-completion-api.jpg[OllamaApi Chat Completion API Diagram, 800, 600]\n\nNOTE: The `OllamaApi` is a low-level API and is not recommended for direct use. Use the `OllamaChatModel` instead.\n\nHere is a simple snippet showing how to use the API programmatically:\n\n[source,java]\n----\nOllamaApi ollamaApi = new OllamaApi(\"YOUR_HOST:YOUR_PORT\");\n\n// Sync request\nvar request = ChatRequest.builder(\"orca-mini\")\n    .stream(false) // not streaming\n    .messages(List.of(\n            Message.builder(Role.SYSTEM)\n                .content(\"You are a geography teacher. You are talking to a student.\")\n                .build(),\n            Message.builder(Role.USER)\n                .content(\"What is the capital of Bulgaria and what is the size? \"\n                        + \"What is the national anthem?\")\n                .build()))\n    .options(OllamaChatOptions.builder().temperature(0.9).build())\n    .build();\n\nChatResponse response = this.ollamaApi.chat(this.request);\n\n// Streaming request\nvar request2 = ChatRequest.builder(\"orca-mini\")\n    .ttream(true) // streaming\n    .messages(List.of(Message.builder(Role.USER)\n        .content(\"What is the capital of Bulgaria and what is the size? \" + \"What is the national anthem?\")\n        .build()))\n    .options(OllamaChatOptions.builder().temperature(0.9).build().toMap())\n    .build();\n\nFlux<ChatResponse> streamingResponse = this.ollamaApi.streamingChat(this.request2);\n----\n"

    "content": "= OpenAI Chat\n\nSpring AI supports the various AI language models from OpenAI, the company behind ChatGPT, which has been instrumental in sparking interest in AI-driven text generation thanks to its creation of industry-leading text generation models and embeddings.\n\n[NOTE]\n====\nStarting from version `2.0.0-M5`, Spring AI uses the official `openai-java` SDK under the hood for all OpenAI models. The transition is expected to be seamless and there are no breaking changes for existing users of the OpenAI API properties and builders. If you find any issues, please report them to us at https://github.com/spring-projects/spring-ai/issues[Spring AI GitHub Issues].\n====\n\n== Prerequisites\n\nYou will need to create an API with OpenAI to access ChatGPT models.\n\nCreate an account at https://platform.openai.com/signup[OpenAI signup page] and generate the token on the https://platform.openai.com/account/api-keys[API Keys page].\n\nThe Spring AI project defines a configuration property named `spring.ai.openai.api-key` that you should set to the value of the `API Key` obtained from openai.com.\n\nYou can set this configuration property in your `application.properties` file:\n\n[source,properties]\n----\nspring.ai.openai.api-key=<your-openai-api-key>\n----\n\nFor enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference a custom environment variable:\n\n[source,yaml]\n----\n# In application.yml\nspring:\n  ai:\n    openai:\n      api-key: ${OPENAI_API_KEY}\n----\n\n[source,bash]\n----\n# In your environment or .env file\nexport OPENAI_API_KEY=<your-openai-api-key>\n----\n\nYou can also set this configuration programmatically in your application code:\n\n[source,java]\n----\n// Retrieve API key from a secure source or environment variable\nString apiKey = System.getenv(\"OPENAI_API_KEY\");\n----\n\n=== Add Repositories and BOM\n\nSpring AI artifacts are published in Maven Central and Spring Snapshot repositories.\nRefer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system.\n\nTo help with dependency management, Spring AI provides a BOM (bill of materials) to ensure that a consistent version of Spring AI is used throughout the entire project. Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build system.\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the OpenAI Chat Client.\nTo enable it add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files:\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-openai</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-openai'\n}\n----\n======\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n=== Chat Properties\n\n==== Retry Properties\n\nThe prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the OpenAI chat model.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.retry.max-attempts   | Maximum number of retry attempts. |  10\n| spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. |  2 sec.\n| spring.ai.retry.backoff.multiplier | Backoff interval multiplier. |  5\n| spring.ai.retry.backoff.max-interval | Maximum backoff duration. |  3 min.\n| spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false\n| spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty\n| spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty\n|====\n\n==== Connection Properties\n\nThe prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.openai.base-url        | The URL to connect to |  https://api.openai.com\n| spring.ai.openai.api-key         | The API Key           |  -\n| spring.ai.openai.organization-id | Optionally, you can specify which organization to use for an API request. |  -\n| spring.ai.openai.project-id      | Optionally, you can specify which project to use for an API request. |  -\n|====\n\nTIP: For users that belong to multiple organizations (or are accessing their projects through their legacy user API key), you can optionally specify which organization and project is used for an API request.\nUsage from these API requests will count as usage for the specified organization and project.\n\n==== User-Agent Header\n\nSpring AI automatically sends a `User-Agent: spring-ai` header with all requests to OpenAI.\nThis helps OpenAI identify requests originating from Spring AI for analytics and support purposes.\nThis header is sent automatically and requires no configuration from Spring AI users.\n\nIf you are an API provider building an OpenAI-compatible service, you can track Spring AI usage by reading the `User-Agent` HTTP header from incoming requests on your server.\n\n==== Configuration Properties\n\n[NOTE]\n====\nEnabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`.\n\nTo enable, spring.ai.model.chat=openai (It is enabled by default)\n\nTo disable, spring.ai.model.chat=none (or any value which doesn't match openai)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix `spring.ai.openai.chat` is the property prefix that lets you configure the chat model implementation for OpenAI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.openai.chat.enabled (Removed and no longer valid) | Enable OpenAI chat model.  | true\n| spring.ai.model.chat | Enable OpenAI chat model.  | openai\n| spring.ai.openai.chat.base-url   | Optional override for the `spring.ai.openai.base-url` property to provide a chat-specific URL. |  -\n| spring.ai.openai.chat.completions-path   | The path to append to the base URL. |  `/v1/chat/completions`\n| spring.ai.openai.chat.api-key   | Optional override for the `spring.ai.openai.api-key` to provide a chat-specific API Key. |  -\n| spring.ai.openai.chat.organization-id | Optionally, you can specify which organization to use for an API request. |  -\n| spring.ai.openai.chat.project-id      | Optionally, you can specify which project to use for an API request. |  -\n| spring.ai.openai.chat.options.model | Name of the OpenAI chat model to use. You can select between models such as: `gpt-5-mini`, `gpt-4o`, `gpt-4o-mini`, `gpt-4-turbo`, `gpt-3.5-turbo`, and more. See the https://platform.openai.com/docs/models[models] page for more information. | `gpt-5-mini`\n| spring.ai.openai.chat.options.temperature | The sampling temperature to use that controls the apparent creativity of generated completions. Higher values will make output more random while lower values will make results more focused and deterministic. It is not recommended to modify `temperature` and `top_p` for the same completions request as the interaction of these two settings is difficult to predict. | 0.8\n| spring.ai.openai.chat.options.frequencyPenalty | Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim. | 0.0f\n| spring.ai.openai.chat.options.logitBias | Modify the likelihood of specified tokens appearing in the completion. | -\n| spring.ai.openai.chat.options.maxTokens | The maximum number of tokens to generate in the chat completion. The total length of input tokens and generated tokens is limited by the model's context length. *Use for non-reasoning models* (e.g., gpt-4o, gpt-3.5-turbo). *Cannot be used with reasoning models* (e.g., o1, o3, o4-mini series). *Mutually exclusive with maxCompletionTokens* - setting both will result in an API error. | -\n| spring.ai.openai.chat.options.maxCompletionTokens | An upper bound for the number of tokens that can be generated for a completion, including visible output tokens and reasoning tokens. *Required for reasoning models* (e.g., o1, o3, o4-mini series). *Cannot be used with non-reasoning models* (e.g., gpt-4o, gpt-3.5-turbo). *Mutually exclusive with maxTokens* - setting both will result in an API error. | -\n| spring.ai.openai.chat.options.n | How many chat completion choices to generate for each input message. Note that you will be charged based on the number of generated tokens across all of the choices. Keep `n` as 1 to minimize costs. | 1\n| spring.ai.openai.chat.options.store | Whether to store the output of this chat completion request for use in our model | false\n| spring.ai.openai.chat.options.metadata | Developer-defined tags and values used for filtering completions in the chat completion dashboard | empty map\n| spring.ai.openai.chat.options.output-modalities | Output types that you would like the model to generate for this request. Most models are capable of generating text, which is the default.\nThe `gpt-4o-audio-preview` model can also be used to generate audio. To request that this model generate both text and audio responses,\nyou can use: `text`, `audio`. Not supported for streaming. | -\n| spring.ai.openai.chat.options.output-audio | Audio parameters for the audio generation. Required when audio output is requested with `output-modalities`: `audio`.\nRequires the `gpt-4o-audio-preview` model and is is not supported for streaming completions. | -\n| spring.ai.openai.chat.options.presencePenalty | Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics. | -\n| spring.ai.openai.chat.options.responseFormat.type | Compatible with `GPT-4o`, `GPT-4o mini`, `GPT-4 Turbo` and all `GPT-3.5 Turbo` models newer than `gpt-3.5-turbo-1106`. The `JSON_OBJECT` type enables JSON mode, which guarantees the message the model generates is valid JSON.\nThe `JSON_SCHEMA` type enables link:https://platform.openai.com/docs/guides/structured-outputs[Structured Outputs] which guarantees the model will match your supplied JSON schema. The JSON_SCHEMA type requires setting the `responseFormat.schema` property as well. | -\n| spring.ai.openai.chat.options.responseFormat.name | Response format schema name. Applicable only for `responseFormat.type=JSON_SCHEMA` | custom_schema\n| spring.ai.openai.chat.options.responseFormat.schema | Response format JSON schema. Applicable only for `responseFormat.type=JSON_SCHEMA` | -\n| spring.ai.openai.chat.options.responseFormat.strict | Response format JSON schema adherence strictness. Applicable only for `responseFormat.type=JSON_SCHEMA` | -\n| spring.ai.openai.chat.options.seed | This feature is in Beta. If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result. | -\n| spring.ai.openai.chat.options.stop | Up to 4 sequences where the API will stop generating further tokens. | -\n| spring.ai.openai.chat.options.topP | An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with `top_p` probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or `temperature` but not both. | -\n| spring.ai.openai.chat.options.tools | A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for. | -\n| spring.ai.openai.chat.options.toolChoice | Controls which (if any) function is called by the model. `none` means the model will not call a function and instead generates a message. `auto` means the model can pick between generating a message or calling a function. Specifying a particular function via `{\"type: \"function\", \"function\": {\"name\": \"my_function\"}}` forces the model to call that function. `none` is the default when no functions are present. `auto` is the default if functions are present. | -\n| spring.ai.openai.chat.options.user | A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. | -\n| spring.ai.openai.chat.options.stream-usage | (For streaming only) Set to add an additional chunk with token usage statistics for the entire request. The `choices` field for this chunk is an empty array and all other chunks will also include a usage field, but with a null value. | false\n| spring.ai.openai.chat.options.parallel-tool-calls | Whether to enable link:https://platform.openai.com/docs/guides/function-calling/parallel-function-calling[parallel function calling] during tool use. | true\n| spring.ai.openai.chat.options.prompt-cache-key | A cache key used by OpenAI to optimize cache hit rates for similar requests. Improves latency and reduces costs. Replaces the deprecated `user` field for caching purposes. link:https://platform.openai.com/docs/guides/prompt-caching[Learn more]. | -\n| spring.ai.openai.chat.options.safety-identifier | A stable identifier to help OpenAI detect users violating usage policies. Should be a hashed value (e.g., hashed username or email). Replaces the deprecated `user` field for safety tracking. link:https://platform.openai.com/docs/guides/safety-best-practices#safety-identifiers[Learn more]. | -\n| spring.ai.openai.chat.options.http-headers | Optional HTTP headers to be added to the chat completion request. To override the `api-key` you need to use an `Authorization` header key, and you have to prefix the key value with the `Bearer` prefix. | -\n| spring.ai.openai.chat.options.tool-names | List of tools, identified by their names, to enable for function calling in a single prompt request. Tools with those names must exist in the ToolCallback registry. | -\n| spring.ai.openai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | -\n| spring.ai.openai.chat.options.internal-tool-execution-enabled | If false, the Spring AI will not handle the tool calls internally, but will proxy them to the client. Then it is the client's responsibility to handle the tool calls, dispatch them to the appropriate function, and return the results. If true (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support | true\n| spring.ai.openai.chat.options.service-tier | Specifies the link:https://platform.openai.com/docs/api-reference/responses/create#responses_create-service_tier[processing type] used for serving the request. | -\n| spring.ai.openai.chat.options.extra-body | Additional parameters to include in the request. Accepts any key-value pairs that are flattened to the top level of the JSON request. Intended for use with OpenAI-compatible servers (vLLM, Ollama, etc.) that support parameters beyond the standard OpenAI API. The official OpenAI API rejects unknown parameters with a 400 error. See <<openai-compatible-servers>> for details. | -\n|====\n\n[NOTE]\n====\nWhen using GPT-5 models such as `gpt-5`, `gpt-5-mini`, and `gpt-5-nano`, the `temperature` parameter is not supported.\nThese models are optimized for reasoning and do not use temperature.\nSpecifying a temperature value will result in an error.\nIn contrast, conversational models like `gpt-5-chat` do support the `temperature` parameter.\n====\n\nNOTE: You can override the common `spring.ai.openai.base-url` and `spring.ai.openai.api-key` for the `ChatModel` and `EmbeddingModel` implementations.\nThe `spring.ai.openai.chat.base-url` and `spring.ai.openai.chat.api-key` properties, if set, take precedence over the common properties.\nThis is useful if you want to use different OpenAI accounts for different models and different model endpoints.\n\nTIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding request-specific <<chat-options>> to the `Prompt` call.\n\n=== Token Limit Parameters: Model-Specific Usage\n\nOpenAI provides two mutually exclusive parameters for controlling token generation limits:\n\n[cols=\"2,3,3\", stripes=even]\n|====\n| Parameter | Use Case | Compatible Models\n\n| `maxTokens` | Non-reasoning models | gpt-4o, gpt-4o-mini, gpt-4-turbo, gpt-3.5-turbo\n| `maxCompletionTokens` | Reasoning models | o1, o1-mini, o1-preview, o3, o4-mini series\n|====\n\nIMPORTANT: These parameters are **mutually exclusive**. Setting both will result in an API error from OpenAI.\n\n==== Usage Examples\n\n**For non-reasoning models (gpt-4o, gpt-3.5-turbo):**\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Explain quantum computing in simple terms.\",\n        OpenAiChatOptions.builder()\n            .model(\"gpt-4o\")\n            .maxTokens(150)  // Use maxTokens for non-reasoning models\n        .build()\n    ));\n----\n\n**For reasoning models (o1, o3 series):**\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Solve this complex math problem step by step: ...\",\n        OpenAiChatOptions.builder()\n            .model(\"o1-preview\")\n            .maxCompletionTokens(1000)  // Use maxCompletionTokens for reasoning models\n        .build()\n    ));\n----\n\n**Builder Pattern Validation:**\nThe OpenAI ChatOptions builder automatically enforces mutual exclusivity with a \"last-set-wins\" approach:\n\n[source,java]\n----\n// This will automatically clear maxTokens and use maxCompletionTokens\nOpenAiChatOptions options = OpenAiChatOptions.builder()\n    .maxTokens(100)           // Set first\n    .maxCompletionTokens(200) // This clears maxTokens and logs a warning\n    .build();\n\n// Result: maxTokens = null, maxCompletionTokens = 200\n----\n\n== Runtime Options [[chat-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions.java] class provides model configurations such as the model to use, the temperature, the frequency penalty, etc.\n\nOn start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties.\n\nAt run-time, you can override the default options by adding new, request-specific options to the `Prompt` call.\nFor example, to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        OpenAiChatOptions.builder()\n            .model(\"gpt-4o\")\n            .temperature(0.4)\n        .build()\n    ));\n----\n\nTIP: In addition to the model specific https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n== Function Calling\n\nYou can register custom Java functions with the `OpenAiChatModel` and have the OpenAI model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions.\nThis is a powerful technique to connect the LLM capabilities with external tools and APIs.\nRead more about xref:api/tools.adoc[Tool Calling].\n\n== Multimodal\n\nMultimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats.\nOpenAI supports text, vision, and audio input modalities.\n\n=== Vision\n\nOpenAI models that offer vision multimodal support include `gpt-4`, `gpt-4o`, and `gpt-4o-mini`.\nRefer to the link:https://platform.openai.com/docs/guides/vision[Vision] guide for more information.\n\nThe OpenAI link:https://platform.openai.com/docs/api-reference/chat/create#chat-create-messages[User Message API] can incorporate a list of base64-encoded images or image urls with the message.\nSpring AI’s link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/messages/Message.java[Message] interface facilitates multimodal AI models by introducing the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-commons/src/main/java/org/springframework/ai/content/Media.java[Media] type.\nThis type encompasses data and details regarding media attachments in messages, utilizing Spring’s `org.springframework.util.MimeType` and a `org.springframework.core.io.Resource` for the raw media data.\n\nBelow is a code example excerpted from link:https://github.com/spring-projects/spring-ai/blob/c9a3e66f90187ce7eae7eb78c462ec622685de6c/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/chat/OpenAiChatModelIT.java#L293[OpenAiChatModelIT.java], illustrating the fusion of user text with an image using the `gpt-4o` model.\n\n[source,java]\n----\nvar imageResource = new ClassPathResource(\"/multimodal.test.png\");\n\nvar userMessage = new UserMessage(\"Explain what do you see on this picture?\",\n        new Media(MimeTypeUtils.IMAGE_PNG, this.imageResource));\n\nChatResponse response = chatModel.call(new Prompt(this.userMessage,\n        OpenAiChatOptions.builder().model(OpenAiApi.ChatModel.GPT_4_O.getValue()).build()));\n----\n\nTIP: GPT_4_VISION_PREVIEW will continue to be available only to existing users of this model starting June 17, 2024. If you are not an existing user, please use the GPT_4_O or GPT_4_TURBO models. More details https://platform.openai.com/docs/deprecations/2024-06-06-gpt-4-32k-and-vision-preview-models[here]\n\nor the image URL equivalent using the `gpt-4o` model:\n\n[source,java]\n----\nvar userMessage = new UserMessage(\"Explain what do you see on this picture?\",\n        new Media(MimeTypeUtils.IMAGE_PNG,\n                URI.create(\"https://docs.spring.io/spring-ai/reference/_images/multimodal.test.png\")));\n\nChatResponse response = chatModel.call(new Prompt(this.userMessage,\n        OpenAiChatOptions.builder().model(OpenAiApi.ChatModel.GPT_4_O.getValue()).build()));\n----\n\nTIP: You can pass multiple images as well.\n\nThe example shows a model taking as an input the `multimodal.test.png` image:\n\nimage::multimodal.test.png[Multimodal Test Image, 200, 200, align=\"left\"]\n\nalong with the text message \"Explain what do you see on this picture?\", and generating a response like this:\n\n----\nThis is an image of a fruit bowl with a simple design. The bowl is made of metal with curved wire edges that\ncreate an open structure, allowing the fruit to be visible from all angles. Inside the bowl, there are two\nyellow bananas resting on top of what appears to be a red apple. The bananas are slightly overripe, as\nindicated by the brown spots on their peels. The bowl has a metal ring at the top, likely to serve as a handle\nfor carrying. The bowl is placed on a flat surface with a neutral-colored background that provides a clear\nview of the fruit inside.\n----\n\n=== Audio\n\nOpenAI models that offer input audio multimodal support include `gpt-4o-audio-preview`.\nRefer to the link:https://platform.openai.com/docs/guides/audio[Audio] guide for more information.\n\nThe OpenAI link:https://platform.openai.com/docs/api-reference/chat/create#chat-create-messages[User Message API] can incorporate a list of base64-encoded audio files with the message.\nSpring AI’s link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/messages/Message.java[Message] interface facilitates multimodal AI models by introducing the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-commons/src/main/java/org/springframework/ai/content/Media.java[Media] type.\nThis type encompasses data and details regarding media attachments in messages, utilizing Spring’s `org.springframework.util.MimeType` and a `org.springframework.core.io.Resource` for the raw media data.\nCurrently, OpenAI support only the following media types: `audio/mp3` and `audio/wav`.\n\nBelow is a code example excerpted from link:https://github.com/spring-projects/spring-ai/blob/c9a3e66f90187ce7eae7eb78c462ec622685de6c/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/chat/OpenAiChatModelIT.java#L442[OpenAiChatModelIT.java], illustrating the fusion of user text with an audio file using the `gpt-4o-audio-preview` model.\n\n[source,java]\n----\nvar audioResource = new ClassPathResource(\"speech1.mp3\");\n\nvar userMessage = new UserMessage(\"What is this recording about?\",\n        List.of(new Media(MimeTypeUtils.parseMimeType(\"audio/mp3\"), audioResource)));\n\nChatResponse response = chatModel.call(new Prompt(List.of(userMessage),\n        OpenAiChatOptions.builder().model(OpenAiApi.ChatModel.GPT_4_O_AUDIO_PREVIEW).build()));\n----\n\nTIP: You can pass multiple audio files as well.\n\n=== Output Audio\n\nOpenAI models that offer input audio multimodal support include `gpt-4o-audio-preview`.\nRefer to the link:https://platform.openai.com/docs/guides/audio[Audio] guide for more information.\n\nThe OpenAI link:https://platform.openai.com/docs/api-reference/chat/create#chat-create-messages[Assistant Message API] can contain a list of base64-encoded audio files with the message.\nSpring AI’s link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/messages/Message.java[Message] interface facilitates

data.\nCurrently, OpenAI support only the following audio types: `audio/mp3` and `audio/wav`.\n\nBelow is a code example, illustrating the response of user text along with an audio byte array, using the `gpt-4o-audio-preview` model:\n\n[source,java]\n----\nvar userMessage = new UserMessage(\"Tell me joke about Spring Framework\");\n\nChatResponse response = chatModel.call(new Prompt(List.of(userMessage),\n        OpenAiChatOptions.builder()\n            .model(OpenAiApi.ChatModel.GPT_4_O_AUDIO_PREVIEW)\n            .outputModalities(List.of(\"text\", \"audio\"))\n            .outputAudio(new AudioParameters(Voice.ALLOY, AudioResponseFormat.WAV))\n            .build()));\n\nString text = response.getResult().getOutput().getText(); // audio transcript\n\nbyte[] waveAudio = response.getResult().getOutput().getMedia().get(0).getDataAsByteArray(); // audio data\n----\n\nYou have to specify an `audio` modality in the `OpenAiChatOptions` to generate audio output.\nThe `AudioParameters` class provides the voice and audio format for the audio output.\n\n== Structured Outputs\n\nOpenAI provides custom https://platform.openai.com/docs/guides/structured-outputs[Structured Outputs] APIs that ensure your model generates responses conforming strictly to your provided `JSON Schema`.\nIn addition to the existing Spring AI model-agnostic xref::api/structured-output-converter.adoc[Structured Output Converter], these APIs offer enhanced control and precision.\n\nNOTE: Currently, OpenAI supports a link:https://platform.openai.com/docs/guides/structured-outputs/supported-schemas[subset of the JSON Schema language] format.\n\n=== Configuration\n\nSpring AI allows you to configure your response format either programmatically using the `OpenAiChatOptions` builder or through application properties.\n\n==== Using the Chat Options Builder\n\nYou can set the response format programmatically with the `OpenAiChatOptions` builder as shown below:\n\n[source,java]\n----\nString jsonSchema = \"\"\"\n        {\n            \"type\": \"object\",\n            \"properties\": {\n                \"steps\": {\n                    \"type\": \"array\",\n                    \"items\": {\n                        \"type\": \"object\",\n                        \"properties\": {\n                            \"explanation\": { \"type\": \"string\" },\n                            \"output\": { \"type\": \"string\" }\n                        },\n                        \"required\": [\"explanation\", \"output\"],\n                        \"additionalProperties\": false\n                    }\n                },\n                \"final_answer\": { \"type\": \"string\" }\n            },\n            \"required\": [\"steps\", \"final_answer\"],\n            \"additionalProperties\": false\n        }\n        \"\"\";\n\nPrompt prompt = new Prompt(\"how can I solve 8x + 7 = -23\",\n        OpenAiChatOptions.builder()\n            .model(ChatModel.GPT_4_O_MINI)\n            .responseFormat(new ResponseFormat(ResponseFormat.Type.JSON_SCHEMA, this.jsonSchema))\n            .build());\n\nChatResponse response = this.openAiChatModel.call(this.prompt);\n----\n\nNOTE: Adhere to the OpenAI link:https://platform.openai.com/docs/guides/structured-outputs/supported-schemas[subset of the JSON Schema language] format.\n\n==== Integrating with BeanOutputConverter Utilities\n\nYou can leverage existing xref::api/structured-output-converter.adoc#_bean_output_converter[BeanOutputConverter] utilities to automatically generate the JSON Schema from your domain objects and later convert the structured response into domain-specific instances:\n\n--\n[tabs]\n======\nJava::\n+\n[source,java]\n----\nrecord MathReasoning(\n    @JsonProperty(required = true, value = \"steps\") Steps steps,\n    @JsonProperty(required = true, value = \"final_answer\") String finalAnswer) {\n\n    record Steps(\n        @JsonProperty(required = true, value = \"items\") Items[] items) {\n\n        record Items(\n            @JsonProperty(required = true, value = \"explanation\") String explanation,\n            @JsonProperty(required = true, value = \"output\") String output) {\n        }\n    }\n}\n\nvar outputConverter = new BeanOutputConverter<>(MathReasoning.class);\n\nvar jsonSchema = this.outputConverter.getJsonSchema();\n\nPrompt prompt = new Prompt(\"how can I solve 8x + 7 = -23\",\n        OpenAiChatOptions.builder()\n            .model(ChatModel.GPT_4_O_MINI)\n            .responseFormat(new ResponseFormat(ResponseFormat.Type.JSON_SCHEMA, this.jsonSchema))\n            .build());\n\nChatResponse response = this.openAiChatModel.call(this.prompt);\nString content = this.response.getResult().getOutput().getText();\n\nMathReasoning mathReasoning = this.outputConverter.convert(this.content);\n----\nKotlin::\n+\n[source,kotlin]\n----\ndata class MathReasoning(\n\tval steps: Steps,\n\t@get:JsonProperty(value = \"final_answer\") val finalAnswer: String) {\n\n\tdata class Steps(val items: Array<Items>) {\n\n\t\tdata class Items(\n\t\t\tval explanation: String,\n\t\t\tval output: String)\n\t}\n}\n\nval outputConverter = BeanOutputConverter(MathReasoning::class.java)\n\nval jsonSchema = outputConverter.jsonSchema;\n\nval prompt = Prompt(\"how can I solve 8x + 7 = -23\",\n\tOpenAiChatOptions.builder()\n\t\t.model(ChatModel.GPT_4_O_MINI)\n\t\t.responseFormat(ResponseFormat(ResponseFormat.Type.JSON_SCHEMA, jsonSchema))\n\t\t.build())\n\nval response = openAiChatModel.call(prompt)\nval content = response.getResult().getOutput().getText()\n\nval mathReasoning = outputConverter.convert(content)\n----\n======\n--\n\nNOTE: Although this is optional for JSON Schema, OpenAI link:https://platform.openai.com/docs/guides/structured-outputs/all-fields-must-be-required#all-fields-must-be-required[mandates] required fields for the structured response to function correctly. Kotlin reflection is used to infer which property are required or not based on the nullability of types and default values of parameters, so for most use case `@get:JsonProperty(required = true)` is not needed. `@get:JsonProperty(value = \"custom_name\")` can be useful to customize the property name. Make sure to generate the annotation on the related getters with this `@get:` syntax, see link:https://kotlinlang.org/docs/annotations.html#annotation-use-site-targets[related documentation].\n\n==== Configuring via Application Properties\n\nAlternatively, when using the OpenAI auto-configuration, you can configure the desired response format through the following application properties:\n\n[source,application.properties]\n----\nspring.ai.openai.api-key=YOUR_API_KEY\nspring.ai.openai.chat.options.model=gpt-4o-mini\n\nspring.ai.openai.chat.options.response-format.type=JSON_SCHEMA\nspring.ai.openai.chat.options.response-format.name=MySchemaName\nspring.ai.openai.chat.options.response-format.schema={\"type\":\"object\",\"properties\":{\"steps\":{\"type\":\"array\",\"items\":{\"type\":\"object\",\"properties\":{\"explanation\":{\"type\":\"string\"},\"output\":{\"type\":\"string\"}},\"required\":[\"explanation\",\"output\"],\"additionalProperties\":false}},\"final_answer\":{\"type\":\"string\"}},\"required\":[\"steps\",\"final_answer\"],\"additionalProperties\":false}\nspring.ai.openai.chat.options.response-format.strict=true\n----\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies.\n\nAdd an `application.properties` file under the `src/main/resources` directory to enable and configure the OpenAi chat model:\n\n[source,application.properties]\n----\nspring.ai.openai.api-key=YOUR_API_KEY\nspring.ai.openai.chat.options.model=gpt-4o\nspring.ai.openai.chat.options.temperature=0.7\n----\n\nTIP: Replace the `api-key` with your OpenAI credentials.\n\nThis will create an `OpenAiChatModel` implementation that you can inject into your classes.\nHere is an example of a simple `@RestController` class that uses the chat model for text generations.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final OpenAiChatModel chatModel;\n\n    @Autowired\n    public ChatController(OpenAiChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map<String,String> generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return

https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatModel.java[OpenAiChatModel] implements the `ChatModel` and `StreamingChatModel` and uses the <<low-level-api>> to connect to the OpenAI service.\n\nAdd the `spring-ai-openai` dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNext, create an `OpenAiChatModel` and use it for text generations:\n\n[source,java]\n----\nvar openAiApi = OpenAiApi.builder()\n            .apiKey(System.getenv(\"OPENAI_API_KEY\"))\n            .build();\nvar openAiChatOptions = OpenAiChatOptions.builder()\n            .model(\"gpt-3.5-turbo\")\n            .temperature(0.4)\n            .maxTokens(200)\n            .build();\nvar chatModel = new OpenAiChatModel(this.openAiApi, this.openAiChatOptions);\n\nChatResponse response = this.chatModel.call(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n\n// Or with streaming responses\nFlux<ChatResponse> response = this.chatModel.stream(\n    new Prompt(\"Generate the names of 5 famous pirates.\"));\n----\n\nThe `OpenAiChatOptions` provides the configuration information for the chat requests.\nThe `OpenAiApi.Builder` and `OpenAiChatOptions.Builder` are fluent options-builders for API client and chat config respectively.\n\n== Low-level OpenAiApi Client [[low-level-api]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/api/OpenAiApi.java[OpenAiApi] provides is lightweight Java client for OpenAI

https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/api/OpenAiApi.java[OpenAiApi.java]'s JavaDoc for further information.\n\n=== Low-level API Examples\n\n* The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/api/OpenAiApiIT.java[OpenAiApiIT.java]

tests show how to use the low-level API to call tool functions.\nBased on the link:https://platform.openai.com/docs/guides/function-calling/parallel-function-calling[OpenAI Function Calling] tutorial.\n\n== Low-level OpenAiFileApi Client [[low-level-file-api]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/api/OpenAiFileApi.java[OpenAiFileApi] provides a lightweight Java client for the OpenAI Files API, enabling file management operations such as uploading, listing, retrieving, deleting files, and accessing file contents. link:https://platform.openai.com/docs/api-reference/files[OpenAI File API]\n\nHere is a simple snippet showing how to use the API programmatically:\n\n[source,java]\n----\nOpenAiFileApi openAiFileApi

file\nResponseEntity<OpenAiFileApi.DeleteFileResponse> deleteResponse = openAiFileApi.deleteFile(\"file-id\");\n\n// Retrieve file content\nResponseEntity<String> fileContent = openAiFileApi.retrieveFileContent(\"file-id\");\n----\n\n=== Low-level File API Examples\n* The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/api/OpenAiFileApiIT.java[OpenAiFileApiIT.java] tests provide some general examples of how to use the lightweight file api library.\n\n== API Key Management\n\nSpring AI provides flexible API key management through the `ApiKey` interface and its implementations. The default implementation, `SimpleApiKey`, is suitable for most use cases, but you can also create custom implementations for more complex scenarios.\n\n=== Default Configuration\n\nBy default, Spring Boot auto-configuration will create an API key bean using the `spring.ai.openai.api-key` property:\n\n[source,properties]\n----\nspring.ai.openai.api-key=your-api-key-here\n----\n\n=== Custom API Key Configuration\n\nYou can create a custom instance of `OpenAiApi` with your own `ApiKey` implementation using the builder pattern:\n\n[source,java]\n----\nApiKey customApiKey = new ApiKey() {\n    @Override\n    public String getValue() {\n        // Custom logic to retrieve API key\n        return \"your-api-key-here\";\n    }\n};\n\nOpenAiApi openAiApi = OpenAiApi.builder()\n    .apiKey(customApiKey)\n    .build();\n\n// Create a chat model with the custom OpenAiApi instance\nOpenAiChatModel chatModel = OpenAiChatModel.builder()\n    .openAiApi(openAiApi)\n    .build();\n// Build the ChatClient using the custom chat model\nChatClient openAiChatClient = ChatClient.builder(chatModel).build();\n----\n\nThis is useful when you need to:\n\n* Retrieve the API key from a secure key store\n* Rotate API keys dynamically\n* Implement custom API key selection logic\n\n== Using Extra Parameters with OpenAI-Compatible Servers [[openai-compatible-servers]]\n\nOpenAI-compatible inference servers like vLLM, Ollama, and others often support additional parameters beyond those defined in OpenAI's standard API.\nFor example, these servers may accept parameters such as `top_k`, `repetition_penalty`, or other sampling controls that the official OpenAI API does not recognize.\n\nThe `extraBody` option allows you to pass arbitrary parameters to these servers.\nAny key-value pairs provided in `extraBody` are included at the top level of the JSON request, enabling you to leverage server-specific features while using Spring AI's OpenAI client.\n\n[IMPORTANT]\n====\nThe `extraBody` parameter is intended for use with OpenAI-compatible servers, not the official OpenAI API.\nThe official OpenAI API applies strict validation and will return an HTTP 400 error (`\"Unknown parameter: 'extra_body'\"`) if unrecognized fields are encountered.\n\nIf you are communicating with the official OpenAI API, you should **never** populate the `extraBody` parameter.\n\nAlso note that the `extraBody` Map is intentionally flattened into the top-level of the JSON request during serialization. So setting `extraBody(Map.of(\"custom_flag\", true))` results in `{\"custom_flag\": true}` at the root of the JSON payload, matching the behavior of official SDKs.\n====\n\n=== Configuration with Properties\n\nYou can configure extra parameters using Spring Boot properties.\nEach property under `spring.ai.openai.chat.options.extra-body` becomes a top-level parameter in the request:\n\n[source,properties]\n----\nspring.ai.openai.base-url=http://localhost:8000\nspring.ai.openai.chat.options.model=meta-llama/Llama-3-8B-Instruct\nspring.ai.openai.chat.options.temperature=0.7\nspring.ai.openai.chat.options.extra-body.top_k=50\nspring.ai.openai.chat.options.extra-body.repetition_penalty=1.1\n----\n\nThis configuration would produce a JSON request like:\n\n[source,json]\n----\n{\n  \"model\": \"meta-llama/Llama-3-8B-Instruct\",\n  \"temperature\": 0.7,\n  \"top_k\": 50,\n  \"repetition_penalty\": 1.1,\n  \"messages\": [...]\n}\n----\n\n=== Runtime Configuration with Builder\n\nYou can also specify extra parameters at runtime using the options builder:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Tell me a creative story\",\n        OpenAiChatOptions.builder()\n            .model(\"meta-llama/Llama-3-8B-Instruct\")\n            .temperature(0.7)\n            .extraBody(Map.of(\n                \"top_k\", 50,\n                \"repetition_penalty\", 1.1,\n                \"frequency_penalty\", 0.5\n            ))\n            .build()\n    ));\n----\n\n=== Example: vLLM Server\n\nWhen running vLLM with a Llama model, you might want to use sampling parameters specific to vLLM:\n\n[source,properties]\n----\nspring.ai.openai.base-url=http://localhost:8000\nspring.ai.openai.chat.options.model=meta-llama/Llama-3-70B-Instruct\nspring.ai.openai.chat.options.extra-body.top_k=40\nspring.ai.openai.chat.options.extra-body.top_p=0.95\nspring.ai.openai.chat.options.extra-body.repetition_penalty=1.05\nspring.ai.openai.chat.options.extra-body.min_p=0.05\n----\n\nRefer to the link:https://docs.vllm.ai/en/latest/[vLLM documentation] for a complete list of supported sampling parameters.\n\n=== Example: Ollama Server\n\nWhen using Ollama through the OpenAI-compatible endpoint, you can pass Ollama-specific parameters:\n\n[source,java]\n----\nOpenAiChatOptions options = OpenAiChatOptions.builder()\n    .model(\"llama3.2\")\n    .extraBody(Map.of(\n        \"num_predict\", 100,\n        \"top_k\", 40,\n        \"repeat_penalty\", 1.1\n    ))\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(\"Generate text\", options));\n----\n\nConsult the link:https://github.com/ollama/ollama/blob/main/docs/api.md[Ollama API documentation] for available parameters.\n\n[NOTE]\n====\nThe `extraBody` parameter accepts any `Map<String, Object>`, allowing you to pass whatever parameters your target server supports.\nSpring AI does not validate these parameters—they are passed directly to the server.\nThis design provides maximum flexibility for working with diverse OpenAI-compatible implementations.\n====\n\n=== Reasoning Content from Reasoning Models\n\nSome OpenAI-compatible servers that support reasoning models (such as DeepSeek R1, vLLM with reasoning parsers) expose the model's internal chain of thought via a `reasoning_content` field in their API responses.\nThis field contains the step-by-step reasoning process the model used to arrive at its final answer.\n\nSpring AI maps this field from the JSON response to the `reasoningContent` key in the AssistantMessage metadata.\n\n[IMPORTANT]\n====\n**Important distinction about `reasoning_content` availability:**\n\n* **OpenAI-compatible servers** (DeepSeek, vLLM): Expose `reasoning_content` in Chat Completions API responses ✅\n* **Official OpenAI models** (GPT-5, o1, o3): Do **NOT** expose reasoning text in Chat Completions API responses ❌\n\nOfficial OpenAI reasoning models hide the chain-of-thought content when using the Chat Completions API.\nThey only expose `reasoning_tokens` count in usage statistics.\nTo access actual reasoning text from official OpenAI models, you must use OpenAI's Responses API (a separate endpoint not currently supported by this client).\n\n**Fallback behavior:** When `reasoning_content` is not provided by the server (e.g., official OpenAI Chat Completions), the `reasoningContent` metadata field will be an empty string.\n====\n\n==== Accessing Reasoning Content\n\nWhen using a compatible server, you can access the reasoning content from the response metadata.\n\n**Using ChatModel directly:**\n\n[source,java]\n----\n// Configure to use DeepSeek R1 or vLLM with a reasoning model\nChatResponse response = chatModel.call(\n    new Prompt(\"Which number is larger: 9.11 or 9.8?\")\n);\n\n// Get the assistant message\nAssistantMessage message = response.getResult().getOutput();\n\n// Access the reasoning content from metadata\nString reasoning = message.getMetadata().get(\"reasoningContent\");\nif (reasoning != null && !reasoning.isEmpty()) {\n    System.out.println(\"Model's reasoning process:\");\n    System.out.println(reasoning);\n}\n\n// The final answer is in the regular content\nSystem.out.println(\"\\nFinal answer:\");\nSystem.out.println(message.getContent());\n----\n\n**Using ChatClient:**\n\n[source,java]\n----\nChatClient chatClient = ChatClient.create(chatModel);\n\nString result = chatClient.prompt()\n    .user(\"Which number is larger: 9.11 or 9.8?\")\n    .call()\n    .chatResponse()\n    .getResult()\n    .getOutput()\n    .getContent();\n\n// To access reasoning content with ChatClient, retrieve the full response\nChatResponse response = chatClient.prompt()\n    .user(\"Which number is larger: 9.11 or 9.8?\")\n    .call()\n    .chatResponse();\n\nAssistantMessage message = response.getResult().getOutput();\nString reasoning = message.getMetadata().get(\"reasoningContent\");\n----\n\n==== Streaming Reasoning Content\n\nWhen using streaming responses, reasoning content is accumulated across chunks just like regular message content:\n\n[source,java]\n----\nFlux<ChatResponse> responseFlux = chatModel.stream(\n    new Prompt(\"Solve this logic puzzle...\")\n);\n\nStringBuilder reasoning = new StringBuilder();\nStringBuilder answer = new StringBuilder();\n\nresponseFlux.subscribe(chunk -> {\n    AssistantMessage message = chunk.getResult().getOutput();\n\n    // Accumulate reasoning if present\n    String reasoningChunk = message.getMetadata().get(\"reasoningContent\");\n    if (reasoningChunk != null) {\n        reasoning.append(reasoningChunk);\n    }\n\n    // Accumulate the final answer\n    if (message.getContent() != null) {\n        answer.append(message.getContent());\n    }\n});\n----\n\n==== Example: DeepSeek R1\n\nDeepSeek R1 is a reasoning model that exposes its internal reasoning process:\n\n[source,properties]\n----\nspring.ai.openai.api-key=${DEEPSEEK_API_KEY}\nspring.ai.openai.base-url=https://api.deepseek.com\nspring.ai.openai.chat.options.model=deepseek-reasoner\n----\n\nWhen you make requests to DeepSeek R1, responses will include both the reasoning content (the model's thought process) and the final answer.\n\nRefer to the link:https://api-docs.deepseek.com/guides/reasoning_model[DeepSeek API documentation] for more details on reasoning models.\n\n==== Example: vLLM with Reasoning Parser\n\nvLLM supports reasoning models when configured with a reasoning parser:\n\n[source,bash]\n----\nvllm serve deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B \\\n    --enable-reasoning \\\n    --reasoning-parser deepseek_r1\n----\n\n[source,properties]\n----\nspring.ai.openai.base-url=http://localhost:8000\nspring.ai.openai.chat.options.model=deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B\n----\n\nConsult the link:https://docs.vllm.ai/en/latest/features/reasoning_outputs.html[vLLM reasoning outputs documentation] for supported reasoning models and parsers.\n\n[NOTE]\n====\nThe availability of `reasoning_content` depends entirely on the inference server you're using.\nNot all OpenAI-compatible servers expose reasoning content, even when using reasoning-capable models.\nAlways refer to your server's API documentation to understand what fields are available in responses.\n====\n"

For each subsequent token, the model considers the results of the tokens with top_p probability mass. We recommend either altering top_k or top_p, but not both. Required range: `0 < x < 1` | 0.9\n| spring.ai.openai.chat.options.stream-usage | (For streaming only) Set to add an additional chunk with token usage statistics for the entire request. The `choices` field for this chunk is an empty array and all other chunks will also include a usage field, but with a null value. | false\n|====\n\nTIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding a request specific <<chat-options>> to the `Prompt` call.\n\n== Runtime Options [[chat-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions.java] provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.\n\nOn start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties.\n\nAt run-time you can override the default options by adding new, request specific, options to the `Prompt` call.\nFor example to override the default model and temperature for a specific request:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\n        \"Generate the names of 5 famous pirates.\",\n        OpenAiChatOptions.builder()\n            .model(\"llama-3.1-sonar-large-128k-online\")\n            .temperature(0.4)\n        .build()\n    ));\n----\n\nTIP: In addition to the model specific https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiChatOptions.java[OpenAiChatOptions] you can use a portable link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/ChatOptions.java[ChatOptions] instance, created with the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/prompt/DefaultChatOptionsBuilder.java[ChatOptions#builder()].\n\n\n== Function Calling\n\nNOTE: Perplexity does not support explicit function calling. Instead, it integrates search results directly into responses.\n\n== Multimodal\n\nNOTE: Currently, the Perplexity API doesn't support media content.\n\n== Sample Controller\n\nhttps://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies.\n\nAdd a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model:\n\n[source,application.properties]\n----\nspring.ai.openai.api-key=<PERPLEXITY_API_KEY>\nspring.ai.openai.base-url=https://api.perplexity.ai\nspring.ai.openai.chat.completions-path=/chat/completions\nspring.ai.openai.chat.options.model=llama-3.1-sonar-small-128k-online\nspring.ai.openai.chat.options.temperature=0.7\n\n# The Perplexity API doesn't support embeddings, so we need to disable it.\nspring.ai.openai.embedding.enabled=false\n----\n\nTIP: replace the `api-key` with your Perplexity Api key.\n\nThis will create a `OpenAiChatModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the chat model for text generations.\n\n[source,java]\n----\n@RestController\npublic class ChatController {\n\n    private final OpenAiChatModel chatModel;\n\n    @Autowired\n    public ChatController(OpenAiChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    @GetMapping(\"/ai/generate\")\n    public Map generate(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        return Map.of(\"generation\", this.chatModel.call(message));\n    }\n\n    @GetMapping(\"/ai/generateStream\")\n\tpublic Flux<ChatResponse> generateStream(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        Prompt prompt = new Prompt(new UserMessage(message));\n        return this.chatModel.stream(prompt);\n    }\n}\n----\n\n== Supported Models\n\nPerplexity supports several models optimized for search-enhanced conversational AI.

    "content": "[[prompt-engineering]]\n= Prompt Engineering Patterns\n\nPractical implementations of Prompt Engineering techniques based on the comprehensive link:https://www.kaggle.com/whitepaper-prompt-engineering[Prompt Engineering Guide].\nThe guide covers the theory, principles, and patterns of effective prompt engineering, while here we demonstrate how to translate those concepts into working Java code using Spring AI's fluent xref::api/chatclient.adoc[ChatClient API].\nThe demo source code used in this article is available at: link:https://github.com/spring-projects/spring-ai-examples/tree/main/prompt-engineering/prompt-engineering-patterns[Prompt Engineering Patterns Examples].\n\n== 1. Configuration\n\nThe configuration section outlines how to set up and tune your Large Language Model (LLM) with Spring AI. \nIt covers selecting the right LLM provider for your use case and configuring important generation parameters that control the quality, style, and format of model outputs.\n\n=== LLM Provider Selection\n\nFor prompt engineering, you will start by choosing a model.\nSpring AI supports xref::api/chat/comparison.adoc[multiple LLM providers] (such as OpenAI, Anthropic, Google GenAI, AWS Bedrock, Ollama and more), letting you switch providers without changing application code - just update your configuration.\nJust add the selected starter dependency `spring-ai-starter-model-<MODEL-PROVIDER-NAME>`.\nFor example, here is how to enable Anthropic Claude API:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-anthropic</artifactId>\n</dependency>\n----\n\nYou can specify the LLM model name like this:\n\n[source,java]\n----\n.options(ChatOptions.builder()\n        .model(\"claude-sonnet-4-6\")  // Use Anthropic's Claude model\n        .build())\n----\n\nFind detailed information for enabling each model in the xref::api/chatmodel.adoc[reference docs].\n\n=== LLM Output Configuration\n\nimage::https://docs.spring.io/spring-ai/reference/_images/chat-options-flow.jpg[width=500,float=right]\n\nBefore we dive into prompt engineering techniques, it's essential to understand how to configure the LLM's output behavior. Spring AI provides several configuration options that let you control various aspects of generation through the xref::api/chatmodel.adoc#_chat_options[ChatOptions] builder.\n\nAll configurations can be applied programmatically as demonstrated in the examples below or through Spring application properties at start time.\n\n==== Temperature\n\nTemperature controls the randomness or \"creativity\" of the model's response. \n\n* *Lower values (0.0-0.3)*: More deterministic, focused responses. Better for factual questions, classification, or tasks where consistency is critical.\n* *Medium values (0.4-0.7)*: Balanced between determinism and creativity. Good for general use cases.\n* *Higher values (0.8-1.0)*: More creative, varied, and potentially surprising responses. Better for creative writing, brainstorming, or generating diverse options.\n\n[source,java]\n----\n.options(ChatOptions.builder()\n        .temperature(0.1)  // Very deterministic output\n        .build())\n----\n\nUnderstanding temperature is crucial for prompt engineering as different techniques benefit from different temperature settings.\n\n==== Output Length (MaxTokens)\n\nThe `maxTokens` parameter limits how many tokens (word pieces) the model can generate in its response.\n\n* *Low values (5-25)*: For single words, short phrases, or classification labels.\n* *Medium values (50-500)*: For paragraphs or short explanations.\n* *High values (1000+)*: For long-form content, stories, or complex explanations.\n\n[source,java]\n----\n.options(ChatOptions.builder()\n        .maxTokens(250)  // Medium-length response\n        .build())\n----\n\nSetting appropriate output length is important to ensure you get complete responses without unnecessary verbosity.\n\n==== Sampling Controls (Top-K and Top-P)\n\nThese parameters give you fine-grained control over the token selection process during generation.\n\n* *Top-K*: Limits token selection to the K most likely next tokens. Higher values (e.g., 40-50) introduce more diversity.\n* *Top-P (nucleus sampling)*: Dynamically selects from the smallest set of tokens whose cumulative probability exceeds P. Values like 0.8-0.95 are common.\n\n[source,java]\n----\n.options(ChatOptions.builder()\n        .topK(40)      // Consider only the top 40 tokens\n        .topP(0.8)     // Sample from tokens that cover 80% of probability mass\n        .build())\n----\n\nThese sampling controls work in conjunction with temperature to shape response characteristics.\n\n==== Structured Response Format\n\nAlong with the plain text response (using `.content()`), Spring AI makes it easy to directly map LLM responses to Java objects using the `.entity()` method.\n\n[source,java]\n----\nenum Sentiment {\n    POSITIVE, NEUTRAL, NEGATIVE\n}\n\nSentiment result = chatClient.prompt(\"...\")\n        .call()\n        .entity(Sentiment.class);\n----\n\nThis feature is particularly powerful when combined with system prompts that instruct the model to return structured data.\n\n==== Model-Specific Options\n\nWhile the portable `ChatOptions` provides a consistent interface across different LLM providers, Spring AI also offers model-specific options classes that expose provider-specific features and configurations. These model-specific options allow you to leverage the unique capabilities of each LLM provider.\n\n[source,java]\n----\n// Using OpenAI-specific options\nOpenAiChatOptions openAiOptions = OpenAiChatOptions.builder()\n        .model(\"gpt-4o\")\n        .temperature(0.2)\n        .frequencyPenalty(0.5)      // OpenAI-specific parameter\n        .presencePenalty(0.3)       // OpenAI-specific parameter\n        .responseFormat(new ResponseFormat(\"json_object\"))  // OpenAI-specific JSON mode\n        .seed(42)                   // OpenAI-specific deterministic generation\n        .build();\n\nString result = chatClient.prompt(\"...\")\n        .options(openAiOptions)\n        .call()\n        .content();\n\n// Using Anthropic-specific options\nAnthropicChatOptions anthropicOptions = AnthropicChatOptions.builder()\n        .model(\"claude-sonnet-4-6\")\n        .temperature(0.2)\n        .topK(40)                   // Anthropic-specific parameter\n        .thinking(AnthropicApi.ThinkingType.ENABLED, 1000)  // Anthropic-specific thinking configuration\n        .build();\n\nString result = chatClient.prompt(\"...\")\n        .options(anthropicOptions)\n        .call()\n        .content();\n----\n\nEach model provider has its own implementation of chat options (e.g., `OpenAiChatOptions`, `AnthropicChatOptions`, `MistralAiChatOptions`) that exposes provider-specific parameters while still implementing the common interface. This approach gives you the flexibility to use portable options for cross-provider compatibility or model-specific options when you need access to unique features of a particular provider.\n\nNote that when using model-specific options, your code becomes tied to that specific provider, reducing portability. It's a trade-off between accessing advanced provider-specific features versus maintaining provider independence in your application.\n\n== 2. Prompt Engineering Techniques\n\nEach section below implements a specific prompt engineering technique from the guide.\nBy following both the \"Prompt Engineering\" guide and these implementations, you'll develop a thorough understanding of not just what prompt engineering techniques are available, but how to effectively implement them in production Java applications.\n\n=== 2.1 Zero-Shot Prompting\n\nZero-shot prompting involves asking an AI to perform a task without providing any examples. This approach tests the model's ability to understand and execute instructions from scratch. Large language models are trained on vast corpora of text, allowing them to understand what tasks like \"translation,\" \"summarization,\" or \"classification\" entail without explicit demonstrations.\n\nZero-shot is ideal for straightforward tasks where the model likely has seen similar examples during training, and when you want to minimize prompt length. However, performance may vary depending on task complexity and how well the instructions are formulated.\n\n[source,java]\n----\n// Implementation of Section 2.1: General prompting / zero shot (page 15)\npublic void pt_zero_shot(ChatClient chatClient) {\n    enum Sentiment {\n        POSITIVE, NEUTRAL, NEGATIVE\n    }\n\n    Sentiment reviewSentiment = chatClient.prompt(\"\"\"\n            Classify movie reviews as POSITIVE, NEUTRAL or NEGATIVE.\n            Review: \"Her\" is a disturbing study revealing the direction\n            humanity is headed if AI is allowed to keep evolving,\n            unchecked. I wish there were more movies like this masterpiece.\n            Sentiment:\n            \"\"\")\n            .options(ChatOptions.builder()\n                    .model(\"claude-sonnet-4-6\")\n                    .temperature(0.1)\n                    .maxTokens(5)\n                    .build())\n            .call()\n            .entity(Sentiment.class);\n\n    System.out.println(\"Output: \" + reviewSentiment);\n}\n----\n\nThis example shows how to classify a movie review sentiment without providing examples. Note the low temperature (0.1) for more deterministic results and the direct `.entity(Sentiment.class)` mapping to a Java enum.\n\n*Reference:* Brown, T. B., et al. (2020). \"Language Models are Few-Shot Learners.\" arXiv:2005.14165. link:https://arxiv.org/abs/2005.14165[https://arxiv.org/abs/2005.14165]\n\n=== 2.2 One-Shot & Few-Shot Prompting\n\nFew-shot prompting provides the model with one or more examples to help guide its responses, particularly useful for tasks requiring specific output formats. By showing the model examples of desired input-output pairs, it can learn the pattern and apply it to new inputs without explicit parameter updates.\n\nOne-shot provides a single example, which is useful when examples are costly or when the pattern is relatively simple. Few-shot uses multiple examples (typically 3-5) to help the model better understand patterns in more complex tasks or to illustrate different variations of correct outputs.\n\n[source,java]\n----\n// Implementation of Section 2.2: One-shot & few-shot (page 16)\npublic void pt_one_shot_few_shots(ChatClient chatClient) {\n    String pizzaOrder = chatClient.prompt(\"\"\"\n            Parse a customer's pizza order into valid JSON\n\n            EXAMPLE 1:\n            I want a small pizza with cheese, tomato sauce, and pepperoni.\n            JSON Response:\n            ```\n            {\n                \"size\": \"small\",\n                \"type\": \"normal\",\n                \"ingredients\": [\"cheese\", \"tomato sauce\", \"pepperoni\"]\n            }\n            ```\n\n            EXAMPLE 2:\n            Can I get a large pizza with tomato sauce, basil and mozzarella.\n            JSON Response:\n            ```\n            {\n                \"size\": \"large\",\n                \"type\": \"normal\",\n                \"ingredients\": [\"tomato sauce\", \"basil\", \"mozzarella\"]\n            }\n            ```\n\n            Now, I would like a large pizza, with the first half cheese and mozzarella.\n            And the other tomato sauce, ham and pineapple.\n            \"\"\")\n            .options(ChatOptions.builder()\n                    .model(\"claude-sonnet-4-6\")\n                    .temperature(0.1)\n                    .maxTokens(250)\n                    .build())\n            .call()\n            .content();\n}\n----\n\nFew-shot prompting is especially effective for tasks requiring specific formatting, handling edge cases, or when the task definition might be ambiguous without examples. The quality and diversity of the examples significantly impact performance.\n\n*Reference:* Brown, T. B., et al. (2020). \"Language Models are Few-Shot Learners.\" arXiv:2005.14165. link:https://arxiv.org/abs/2005.14165[https://arxiv.org/abs/2005.14165]\n\n=== 2.3 System, contextual and role prompting\n\n==== System Prompting\n\nSystem prompting sets the overall context and purpose for the language model, defining the \"big picture\" of what the model should be doing. It establishes the behavioral framework, constraints, and high-level objectives for the model's responses, separate from the specific user queries.\n\nSystem prompts act as a persistent \"mission statement\" throughout the conversation, allowing you to set global parameters like output format, tone, ethical boundaries, or role definitions. Unlike user prompts which focus on specific tasks, system prompts frame how all user prompts should be interpreted.\n\n[source,java]\n----\n// Implementation of Section 2.3.1: System prompting\npublic void pt_system_prompting_1(ChatClient chatClient) {\n    String movieReview = chatClient\n            .prompt()\n            .system(\"Classify movie reviews as positive, neutral or negative. Only return the label in uppercase.\")\n            .user(\"\"\"\n                    Review: \"Her\" is a disturbing study revealing the direction\n                    humanity is headed if AI is allowed to keep evolving,\n                    unchecked. It's so disturbing I couldn't watch it.\n\n                    Sentiment:\n                    \"\"\")\n            .options(ChatOptions.builder()\n                    .model(\"claude-sonnet-4-6\")\n                    .temperature(1.0)\n                    .topK(40)\n                    .topP(0.8)\n                    .maxTokens(5)\n                    .build())\n            .call()\n            .content();\n}\n----\n\nSystem prompting is particularly powerful when combined with Spring AI's entity mapping capabilities:\n\n[source,java]\n----\n// Implementation of Section 2.3.1: System prompting with JSON output\nrecord MovieReviews(Movie[] movie_reviews) {\n    enum Sentiment {\n        POSITIVE, NEUTRAL, NEGATIVE\n    }\n\n    record Movie(Sentiment sentiment, String name) {\n    }\n}\n\nMovieReviews movieReviews = chatClient\n        .prompt()\n        .system(\"\"\"\n                Classify movie reviews as positive, neutral or negative. Return\n                valid JSON.\n                \"\"\")\n        .user(\"\"\"\n                Review: \"Her\" is a disturbing study revealing the direction\n                humanity is headed if AI is allowed to keep evolving,\n                unchecked. It's so disturbing I couldn't watch it.\n\n                JSON Response:\n                \"\"\")\n        .call()\n        .entity(MovieReviews.class);\n----\n\nSystem prompts are especially valuable for multi-turn conversations, ensuring consistent behavior across multiple queries, and for establishing format constraints like JSON output that should apply to all responses.\n\n*Reference:* OpenAI. (2022). \"System Message.\" link:https://platform.openai.com/docs/guides/chat/introduction[https://platform.openai.com/docs/guides/chat/introduction]\n\n==== Role Prompting\n\nRole prompting instructs the model to adopt a specific role or persona, which affects how it generates content. By assigning a particular identity, expertise, or perspective to the model, you can influence the style, tone, depth, and framing of its responses.\n\nRole prompting leverages the model's ability to simulate different expertise domains and communication styles. Common roles include expert (e.g., \"You are an experienced data scientist\"), professional (e.g., \"Act as a travel guide\"), or stylistic character (e.g., \"Explain like you're Shakespeare\").\n\n[source,java]\n----\n// Implementation of Section 2.3.2: Role prompting\npublic void pt_role_prompting_1(ChatClient chatClient) {\n    String travelSuggestions = chatClient\n            .prompt()\n            .system(\"\"\"\n                    I want you to act as a travel guide. I will write to you\n                    about my location and you will suggest 3 places to visit near\n                    me. In some cases, I will also give you the type of places I\n                    will visit.\n                    \"\"\")\n            .user(\"\"\"\n                    My suggestion: \"I am in Amsterdam and I want to visit only museums.\"\n                    Travel Suggestions:\n                    \"\"\")\n            .call()\n            .content();\n}\n----\n\nRole prompting can be enhanced with style instructions:\n\n[source,java]\n----\n// Implementation of Section 2.3.2: Role prompting with style instructions\npublic void pt_role_prompting_2(ChatClient chatClient) {\n    String humorousTravelSuggestions = chatClient\n            .prompt()\n            .system(\"\"\"\n                    I want you to act as a travel guide. I will write to you about\n                    my location and you will suggest 3 places to visit near me in\n                    a humorous style.\n                    \"\"\")\n            .user(\"\"\"\n                    My suggestion: \"I am in Amsterdam and I want to visit only museums.\"\n                    Travel Suggestions:\n                    \"\"\")\n            .call()\n            .content();\n}\n----\n\nThis technique is particularly effective for specialized domain knowledge, achieving a consistent tone across responses, and creating more engaging, personalized interactions with users.\n\n*Reference:* Shanahan, M., et al. (2023). \"Role-Play with Large Language Models.\" arXiv:2305.16367. link:https://arxiv.org/abs/2305.16367[https://arxiv.org/abs/2305.16367]\n\n==== Contextual Prompting\n\nContextual prompting provides additional background information to the model by passing context parameters. This technique enriches the model's understanding of the specific situation, enabling more relevant and tailored responses without cluttering the main instruction.\n\nBy supplying contextual information, you help the model understand the specific domain, audience, constraints, or background facts relevant to the current query. This leads to more accurate, relevant, and appropriately framed responses.\n\n[source,java]\n----\n// Implementation of Section 2.3.3: Contextual prompting\npublic void pt_contextual_prompting(ChatClient chatClient) {\n    String articleSuggestions = chatClient\n            .prompt()\n            .user(u -> u.text(\"\"\"\n                    Suggest 3 topics to write an article about with a few lines of\n                    description of what this article should contain.\n\n                    Context: {context}\n                    \"\"\")\n                    .param(\"context\", \"You are writing for a blog about retro 80's arcade video games.\"))\n            .call()\n            .content();\n}\n----\n\nSpring AI makes contextual prompting clean with the param() method to inject context variables. This technique is particularly valuable when the model needs specific domain knowledge, when adapting responses to particular audiences or scenarios, and for ensuring responses are aligned with particular constraints or requirements.\n\n*Reference:* Liu, P., et al.

This technique encourages the model to first \"step back\" from the immediate question to consider the broader context, fundamental principles, or general knowledge relevant to the problem before addressing the specific query.\n\nBy decomposing complex problems into more manageable components and establishing foundational knowledge first, the model can provide more accurate responses to difficult questions.\n\n[source,java]\n----\n// Implementation of Section 2.4: Step-back prompting\npublic void pt_step_back_prompting(ChatClient.Builder chatClientBuilder) {\n    // Set common options for the chat client\n    var chatClient = chatClientBuilder\n            .defaultOptions(ChatOptions.builder()\n                    .model(\"claude-sonnet-4-6\")\n                    .temperature(1.0)\n                    .topK(40)\n                    .topP(0.8)\n                    .maxTokens(1024)\n                    .build())\n            .build();\n\n    // First get high-level concepts\n    String stepBack = chatClient\n            .prompt(\"\"\"\n                    Based on popular first-person shooter action games, what are\n                    5 fictional key settings that contribute to a challenging and\n                    engaging level storyline in a first-person shooter video game?\n                    \"\"\")\n            .call()\n            .content();\n\n    // Then use those concepts in the main task\n    String story = chatClient\n            .prompt()\n            .user(u -> u.text(\"\"\"\n                    Write a one paragraph storyline for a new level of a first-\n                    person shooter video game that is challenging and engaging.\n\n                    Context: {step-back}\n                    \"\"\")\n                    .param(\"step-back\", stepBack))\n            .call()\n            .content();\n}\n----\n\nStep-back prompting is particularly effective for complex reasoning tasks, problems requiring specialized domain knowledge, and when you want more comprehensive and thoughtful responses rather than immediate answers.\n\n*Reference:* Zheng, Z., et al.

By explicitly asking the model to show its work or think through a problem in logical steps, you can dramatically improve performance on tasks requiring multi-step reasoning.\n\nCoT works by encouraging the model to generate intermediate reasoning steps before producing a final answer, similar to how humans solve complex problems. This makes the model's thinking process explicit and helps it arrive at more accurate conclusions.\n\n[source,java]\n----\n// Implementation of Section 2.5: Chain of Thought (CoT) - Zero-shot approach\npublic void pt_chain_of_thought_zero_shot(ChatClient chatClient) {\n    String output = chatClient\n            .prompt(\"\"\"\n                    When I was 3 years old, my partner was 3 times my age.

Now I am 40\n                    years old, so my brother is 40 - 2 = 38 years old. The answer\n                    is 38.\n                    Q: When I was 3 years old, my partner was 3 times my age. Now,\n                    I am 20 years old. How old is my partner?

CoT is especially valuable for mathematical problems, logical reasoning tasks, and any question requiring multi-step reasoning. It helps reduce errors by making intermediate reasoning explicit.\n\n*Reference:* Wei, J., et al.

This technique addresses the variability in LLM outputs by sampling diverse reasoning paths for the same problem and selecting the most consistent answer through majority voting.\n\nBy generating multiple reasoning paths with different temperature or sampling settings, then aggregating the final answers, self-consistency improves accuracy on complex reasoning tasks. It's essentially an ensemble method for LLM outputs.\n\n[source,java]\n----\n// Implementation of Section 2.6: Self-consistency\npublic void pt_self_consistency(ChatClient chatClient) {\n    String email = \"\"\"\n            Hi,\n            I have seen you use Wordpress for your website.

It treats problem-solving as a search process where the model generates different intermediate steps, evaluates their promise, and explores the most promising paths.\n\nThis technique is particularly powerful for complex problems with multiple possible approaches or when the solution requires exploring various alternatives before finding the optimal path.\n\n[NOTE]\n====\nThe original \"Prompt Engineering\" guide doesn't provide implementation examples for ToT, likely due to its complexity.

By combining these techniques with Spring's powerful entity mapping and fluent API, developers can build sophisticated AI-powered applications with clean, maintainable code.\n\nThe most effective approach often involves combining multiple techniques - for example, using system prompts with few-shot examples, or chain-of-thought with role prompting. Spring AI's flexible API makes these combinations straightforward to implement.\n\nFor production applications, remember to:\n\n1. Test prompts with different parameters (temperature, top-k, top-p)\n2. Consider using self-consistency for critical decision-making\n3. Leverage Spring AI's entity mapping for type-safe responses\n4. Use contextual prompting to provide application-specific knowledge\n\nWith these techniques and Spring AI's powerful abstractions, you can create robust AI-powered applications that deliver consistent, high-quality results.\n\n== References\n\n1.

This can be a limitation when you want to maintain context or state across multiple interactions. To address this, Spring AI provides chat memory features that allow you to store and retrieve information across multiple interactions with the LLM.\n\nThe `ChatMemory` abstraction allows you to implement various types of memory to support different use cases. The underlying storage of the messages is handled by the `ChatMemoryRepository`, whose sole responsibility is to store and retrieve messages. It's up to the `ChatMemory` implementation to decide which messages to keep and when to remove them. Examples of strategies could include keeping the last N messages, keeping messages for a certain time period, or keeping messages up to a certain token limit.\n\nBefore choosing a memory type, it's essential to understand the difference between chat memory and chat history.\n\n* *Chat Memory*. The information that a large-language model retains and uses to maintain contextual awareness throughout a conversation.\n* *Chat History*. The entire conversation history, including all messages exchanged between the user and the model.\n\nThe `ChatMemory` abstraction is designed to manage the _chat memory_. It allows you to store and retrieve messages that are relevant to the current conversation context. However, it is not the best fit for storing the _chat history_. If you need to maintain a complete record of all the messages exchanged, you should consider using a different approach, such as relying on Spring Data for efficient storage and retrieval of the complete chat history.\n\n== Quick Start\n\nSpring AI auto-configures a `ChatMemory` bean that you can use directly in your application. By default, it uses an in-memory repository to store messages (`InMemoryChatMemoryRepository`) and a `MessageWindowChatMemory` implementation to manage the conversation history. If a different repository is already configured (e.g., Cassandra, JDBC, or Neo4j), Spring AI will use that instead.\n\n[source,java]\n----\n@Autowired\nChatMemory chatMemory;\n----\n\nThe following sections will describe further the different memory types and repositories available in Spring AI.\n\n== Memory Types\n\nThe `ChatMemory` abstraction allows you to implement various types of memory to suit different use cases. The choice of memory type can significantly impact the performance and behavior of your application. This section describes the built-in memory types provided by Spring AI and their characteristics.\n\n=== Message Window Chat Memory\n\n`MessageWindowChatMemory` maintains a window of messages up to a specified maximum size. When the number of messages exceeds the maximum, older messages are removed while preserving system messages. The default window size is 20 messages.\n\n[source,java]\n----\nMessageWindowChatMemory memory = MessageWindowChatMemory.builder()\n    .maxMessages(10)\n    .build();\n----\n\nThis is the default message type used by Spring AI to auto-configure a `ChatMemory` bean.\n\n== Memory Storage\n\nSpring AI offers the `ChatMemoryRepository` abstraction for storing chat memory. This section describes the built-in repositories provided by Spring AI and how to use them, but you can also implement your own repository if needed.\n\n=== In-Memory Repository\n\n`InMemoryChatMemoryRepository` stores messages in memory using a `ConcurrentHashMap`.\n\nBy default, if no other repository is already configured, Spring AI auto-configures a `ChatMemoryRepository` bean of type `InMemoryChatMemoryRepository` that you can use directly in your application.\n\n[source,java]\n----\n@Autowired\nChatMemoryRepository chatMemoryRepository;\n----\n\nIf you'd rather create the `InMemoryChatMemoryRepository` manually, you can do so as follows:\n\n[source,java]\n----\nChatMemoryRepository repository = new InMemoryChatMemoryRepository();\n----\n\n=== JdbcChatMemoryRepository\n\n`JdbcChatMemoryRepository` is a built-in implementation that uses JDBC to store messages in a relational database. It supports multiple databases out-of-the-box and is suitable for applications that require persistent storage of chat memory.\n\nMessages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history.\n\nFirst, add the following dependency to your project:\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-chat-memory-repository-jdbc</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-jdbc'\n}\n----\n======\n\nSpring AI provides auto-configuration for the `JdbcChatMemoryRepository`, that you can use directly in your application.\n\n[source,java]\n----\n@Autowired\nJdbcChatMemoryRepository chatMemoryRepository;\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\nIf you'd rather create the `JdbcChatMemoryRepository` manually, you can do so by providing a `JdbcTemplate` instance and a `JdbcChatMemoryRepositoryDialect`:\n\n[source,java]\n----\nChatMemoryRepository chatMemoryRepository = JdbcChatMemoryRepository.builder()\n    .jdbcTemplate(jdbcTemplate)\n    .dialect(new PostgresChatMemoryRepositoryDialect())\n    .build();\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\n==== Supported Databases and Dialect Abstraction\n\nSpring AI supports multiple relational databases via a dialect abstraction. The following databases are supported out-of-the-box:\n\n- PostgreSQL\n- MySQL / MariaDB\n- SQL Server\n- HSQLDB\n- Oracle Database\n\nThe correct dialect can be auto-detected from the JDBC URL when using `JdbcChatMemoryRepositoryDialect.from(DataSource)`. You can extend support for other databases by implementing the `JdbcChatMemoryRepositoryDialect` interface.\n\n==== Configuration Properties\n\n[cols=\"2,5,1\",stripes=even]\n|===\n|Property | Description | Default Value\n| `spring.ai.chat.memory.repository.jdbc.initialize-schema` | Controls when to initialize the schema. Values: `embedded` (default), `always`, `never`. | `embedded`\n| `spring.ai.chat.memory.repository.jdbc.schema` | Location of the schema script to use for initialization. Supports `classpath:` URLs and platform placeholders. | `classpath:org/springframework/ai/chat/memory/repository/jdbc/schema-@@platform@@.sql`\n| `spring.ai.chat.memory.repository.jdbc.platform` | Platform to use in initialization scripts if the @@platform@@ placeholder is used. | _auto-detected_\n|===\n\n==== Schema Initialization\n\nThe auto-configuration will automatically create the `SPRING_AI_CHAT_MEMORY` table on startup, using a vendor-specific SQL script for your database. By default, schema initialization runs only for embedded databases (H2, HSQL, Derby, etc.).\n\nYou can control schema initialization using the `spring.ai.chat.memory.repository.jdbc.initialize-schema` property:\n\n[source,properties]\n----\nspring.ai.chat.memory.repository.jdbc.initialize-schema=embedded # Only for embedded DBs (default)\nspring.ai.chat.memory.repository.jdbc.initialize-schema=always   # Always initialize\nspring.ai.chat.memory.repository.jdbc.initialize-schema=never    # Never initialize (useful with Flyway/Liquibase)\n----\n\nTo override the schema script location, use:\n\n[source,properties]\n----\nspring.ai.chat.memory.repository.jdbc.schema=classpath:/custom/path/schema-mysql.sql\n----\n\n==== Extending Dialects\n\nTo add support for a new database, implement the `JdbcChatMemoryRepositoryDialect` interface and provide SQL for selecting, inserting, and deleting messages. You can then pass your custom dialect to the repository builder.\n\n[source,java]\n----\nChatMemoryRepository chatMemoryRepository = JdbcChatMemoryRepository.builder()\n    .jdbcTemplate(jdbcTemplate)\n    .dialect(new MyCustomDbDialect())\n    .build();\n----\n\n\n=== CassandraChatMemoryRepository\n\n`CassandraChatMemoryRepository` uses Apache Cassandra to store messages.  It is suitable for applications that require persistent storage of chat memory, especially for availability, durability, scale, and when taking advantage of time-to-live (TTL) feature.\n\n`CassandraChatMemoryRepository` has a time-series schema, keeping record of all past chat windows, valuable for governance and auditing.  Setting time-to-live to some value, for example three years, is recommended.\n\nMessages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history.\n\nTo use `CassandraChatMemoryRepository` first, add the dependency to your project:\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-chat-memory-repository-cassandra</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-cassandra'\n}\n----\n======\n\nSpring AI provides auto-configuration for the `CassandraChatMemoryRepository` that you can use directly in your application.\n\n[source,java]\n----\n@Autowired\nCassandraChatMemoryRepository chatMemoryRepository;\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\nIf you'd rather create the `CassandraChatMemoryRepository` manually, you can do so by providing a `CassandraChatMemoryRepositoryConfig` instance:\n\n[source,java]\n----\nChatMemoryRepository chatMemoryRepository = CassandraChatMemoryRepository\n    .create(CassandraChatMemoryRepositoryConfig.builder().withCqlSession(cqlSession));\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\n==== Configuration Properties\n\n[cols=\"2,5,1\",stripes=even]\n|===\n|Property | Description | Default Value\n| `spring.cassandra.contactPoints` | Host(s) to initiate cluster discovery | `127.0.0.1`\n| `spring.cassandra.port` | Cassandra native protocol port to connect to | `9042`\n| `spring.cassandra.localDatacenter` | Cassandra datacenter to connect to | `datacenter1`\n| `spring.ai.chat.memory.cassandra.time-to-live` | Time to live (TTL) for messages written in Cassandra |\n| `spring.ai.chat.memory.cassandra.keyspace` | Cassandra keyspace | `springframework`\n| `spring.ai.chat.memory.cassandra.messages-column` | Cassandra column name for messages | `springframework`\n| `spring.ai.chat.memory.cassandra.table` | Cassandra table | `ai_chat_memory`\n| `spring.ai.chat.memory.cassandra.initialize-schema` | Whether to initialize the schema on startup. | `true`\n|===\n\n==== Schema Initialization\n\nThe auto-configuration will automatically create the `ai_chat_memory` table.\n\nYou can disable the schema initialization by setting the property `spring.ai.chat.memory.repository.cassandra.initialize-schema` to `false`.\n\n=== Neo4j ChatMemoryRepository\n\n`Neo4jChatMemoryRepository` is a built-in implementation that uses Neo4j to store chat messages as nodes and relationships in a property graph database. It is suitable for applications that want to leverage Neo4j's graph capabilities for chat memory persistence.\n\nMessages are retrieved in ascending message index order (oldest-to-newest), which is the expected format for LLM conversation history.\n\nFirst, add the following dependency to your project:\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-chat-memory-repository-neo4j</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-neo4j'\n}\n----\n======\n\nSpring AI provides auto-configuration for the `Neo4jChatMemoryRepository`, which you can use directly in your application.\n\n[source,java]\n----\n@Autowired\nNeo4jChatMemoryRepository chatMemoryRepository;\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\nIf you'd rather create the `Neo4jChatMemoryRepository` manually, you can do so by providing a Neo4j `Driver` instance:\n\n[source,java]\n----\nChatMemoryRepository chatMemoryRepository = Neo4jChatMemoryRepository.builder()\n    .driver(driver)\n    .build();\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\n==== Configuration Properties\n\n[cols=\"2,5,1\",stripes=even]\n|===\n|Property | Description | Default Value\n| `spring.ai.chat.memory.repository.neo4j.sessionLabel` | The label for the nodes that store conversation sessions | `Session`\n| `spring.ai.chat.memory.repository.neo4j.messageLabel` | The label for the nodes that store messages | `Message`\n| `spring.ai.chat.memory.repository.neo4j.toolCallLabel` | The label for nodes that store tool calls (e.g. in Assistant Messages) | `ToolCall`\n| `spring.ai.chat.memory.repository.neo4j.metadataLabel` | The label for nodes that store message metadata | `Metadata`\n| `spring.ai.chat.memory.repository.neo4j.toolResponseLabel` | The label for the nodes that store tool responses | `ToolResponse`\n| `spring.ai.chat.memory.repository.neo4j.mediaLabel` | The label for the nodes that store media associated with a message | `Media`\n|===\n\n==== Index Initialization\n\nThe Neo4j repository will automatically ensure that indexes are created for conversation IDs and message indices to optimize performance. If you use custom labels, indexes will be created for those labels as well. No schema initialization is required, but you should ensure your Neo4j instance is accessible to your application.\n\n=== CosmosDBChatMemoryRepository\n\n`CosmosDBChatMemoryRepository` is a built-in implementation that uses Azure Cosmos DB NoSQL API to store messages. It is suitable for applications that require a globally distributed, highly scalable document database for chat memory persistence. The repository uses the conversation ID as the partition key to ensure efficient data distribution and fast retrieval.\n\nMessages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history.\n\nFirst, add the following dependency to your project:\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-chat-memory-repository-cosmos-db</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-cosmos-db'\n}\n----\n======\n\nSpring AI provides auto-configuration for the `CosmosDBChatMemoryRepository`, which you can use directly in your application.\n\n[source,java]\n----\n@Autowired\nCosmosDBChatMemoryRepository chatMemoryRepository;\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\nIf you'd rather create the `CosmosDBChatMemoryRepository` manually, you can do so by providing a `CosmosDBChatMemoryRepositoryConfig` instance:\n\n[source,java]\n----\nChatMemoryRepository chatMemoryRepository = CosmosDBChatMemoryRepository\n    .create(CosmosDBChatMemoryRepositoryConfig.builder()\n        .withCosmosClient(cosmosAsyncClient)\n        .withDatabaseName(\"chat-memory-db\")\n        .withContainerName(\"conversations\")\n        .build());\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\n==== Configuration Properties\n\n[cols=\"2,5,1\",stripes=even]\n|===\n|Property | Description | Default Value\n| `spring.ai.chat.memory.repository.cosmosdb.endpoint` | Azure Cosmos DB endpoint URI. Required for auto-configuration. |\n| `spring.ai.chat.memory.repository.cosmosdb.key` | Azure Cosmos DB primary or secondary key.

The container is configured with the conversation ID as the partition key (`/conversationId`) to ensure optimal performance for chat memory operations. No manual schema setup is required.\n\nYou can customize the database and container names using the configuration properties mentioned above.\n\n=== MongoChatMemoryRepository\n\n`MongoChatMemoryRepository` is a built-in implementation that uses MongoDB to store messages. It is suitable for applications that require a flexible, document-oriented database for chat memory persistence.\n\nMessages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history. This ordering is consistent across all chat memory repository implementations.\n\nFirst, add the following dependency to your project:\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-chat-memory-repository-mongodb</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-mongodb'\n}\n----\n======\n\nSpring AI provides auto-configuration for the `MongoChatMemoryRepository`, which you can use directly in your application.\n\n[source,java]\n----\n@Autowired\nMongoChatMemoryRepository chatMemoryRepository;\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\nIf you'd rather create the `MongoChatMemoryRepository` manually, you can do so by providing a `MongoTemplate` instance:\n\n[source,java]\n----\nChatMemoryRepository chatMemoryRepository = MongoChatMemoryRepository.builder()\n    .mongoTemplate(mongoTemplate)\n    .build();\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\n==== Configuration Properties\n\n[cols=\"2,5,1\",stripes=even]\n|===\n|Property | Description | Default Value\n| `spring.ai.chat.memory.repository.mongo.create-indices` | Should indices be created or recreated automatically on startup.

not already exist.\n\n=== RedisChatMemoryRepository\n\n`RedisChatMemoryRepository` is a built-in implementation that uses Redis Stack (with Redis Query Engine and RedisJSON) to store chat messages.\nIt is suitable for applications that require high-performance, low-latency chat memory persistence with optional TTL (time-to-live) support and advanced querying capabilities.\n\nThe repository stores messages as JSON documents and creates a search index for efficient querying.\nIt also provides extended query capabilities through the `AdvancedRedisChatMemoryRepository` interface for searching messages by content, type, time range, and metadata.\n\nMessages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history.\n\nFirst, add the following dependency to your project:\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-chat-memory-repository-redis</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation

.chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\nIf you'd rather create the `RedisChatMemoryRepository` manually, you can do so by providing a `JedisPooled` client:\n\n[source,java]\n----\nJedisPooled jedisClient = new JedisPooled(\"localhost\", 6379);\n\nChatMemoryRepository chatMemoryRepository = RedisChatMemoryRepository.builder()\n    .jedisClient(jedisClient)\n    .indexName(\"my-chat-index\")\n    .keyPrefix(\"my-chat:\")\n    .timeToLive(Duration.ofHours(24))\n    .build();\n\nChatMemory chatMemory = MessageWindowChatMemory.builder()\n    .chatMemoryRepository(chatMemoryRepository)\n    .maxMessages(10)\n    .build();\n----\n\n==== Configuration Properties\n\n[cols=\"2,5,1\",stripes=even]\n|===\n|Property | Description | Default Value\n| `spring.ai.chat.memory.redis.host` | Redis server host | `localhost`\n| `spring.ai.chat.memory.redis.port` | Redis server port | `6379`\n| `spring.ai.chat.memory.redis.index-name` | Name of the Redis search index | `chat-memory-idx`\n| `spring.ai.chat.memory.redis.key-prefix` | Key prefix for chat memory

`spring.ai.chat.memory.redis.max-messages-per-conversation` | Maximum number of messages to return per conversation | `1000`\n|===\n\n==== Advanced Querying\n\nThe `RedisChatMemoryRepository` also implements `AdvancedRedisChatMemoryRepository`, which provides extended query capabilities:\n\n[source,java]\n----\n// Cast to access advanced features\nAdvancedRedisChatMemoryRepository advancedRepo = (AdvancedRedisChatMemoryRepository) chatMemoryRepository;\n\n// Find messages by type across all conversations\nList<MessageWithConversation> userMessages = advancedRepo.findByType(MessageType.USER, 100);\n\n// Find messages containing specific content\nList<MessageWithConversation> results = advancedRepo.findByContent(\"Spring AI\", 50);\n\n// Find messages within a time range\nList<MessageWithConversation> recentMessages = advancedRepo.findByTimeRange(\n    conversationId,\n    Instant.now().minus(Duration.ofHours(1)),\n    Instant.now(),\n    100\n);\n\n// Find messages by metadata\nList<MessageWithConversation> priorityMessages = advancedRepo.findByMetadata(\"priority\", \"high\", 50);\n\n// Execute custom Redis queries\nList<MessageWithConversation> customResults = advancedRepo.executeQuery(\"@type:USER @content:Redis\", 100);\n----\n\n==== Metadata Field Indexing\n\nTo enable efficient querying on custom metadata fields, you can configure metadata field definitions:\n\n[source,properties]\n----\nspring.ai.chat.memory.redis.metadata-fields[0].name=priority\nspring.ai.chat.memory.redis.metadata-fields[0].type=tag\nspring.ai.chat.memory.redis.metadata-fields[1].name=score\nspring.ai.chat.memory.redis.metadata-fields[1].type=numeric\nspring.ai.chat.memory.redis.metadata-fields[2].name=category\nspring.ai.chat.memory.redis.metadata-fields[2].type=tag\n----\n\nSupported field types are: `tag` (for exact match filtering), `text` (for full-text search), and `numeric` (for range queries).\n\n==== Schema Initialization\n\nThe auto-configuration will automatically create the Redis search index on startup if it does not already exist.\nYou can disable this behavior by setting `spring.ai.chat.memory.redis.initialize-schema=false`.\n\n==== Requirements\n\n* Redis Stack 7.0 or higher (includes Redis Query Engine and RedisJSON modules)\n* Jedis client library (included as a dependency)\n\n== Memory in Chat Client\n\nWhen using the ChatClient API, you can provide a `ChatMemory` implementation to maintain conversation context across multiple interactions.\n\nSpring AI provides a few built-in Advisors that you can use to configure the memory behavior of the `ChatClient`, based on your needs.\n\nWARNING: Currently, the intermediate messages exchanged with a large-language model when performing tool calls are not stored in the memory. This is a limitation of the current implementation and will be addressed in future releases. If you need to store these messages, refer to the instructions for the xref:api/tools.adoc#_user_controlled_tool_execution[User Controlled Tool Execution].\n\n* `MessageChatMemoryAdvisor`. This advisor manages the conversation memory using the provided `ChatMemory` implementation. On each interaction, it retrieves the conversation history from the memory and includes it in the prompt as a collection of messages.\n* `PromptChatMemoryAdvisor`. This advisor manages the conversation memory using the provided `ChatMemory` implementation. On each interaction, it retrieves the conversation history from the memory and appends it to the system prompt as plain text.\n* `VectorStoreChatMemoryAdvisor`. This advisor manages the conversation memory using the provided `VectorStore` implementation. On each interaction, it retrieves the conversation history from the vector store and appends it to the system message as plain text.\n\nFor example, if you want to use `MessageWindowChatMemory` with the `MessageChatMemoryAdvisor`, you can configure it as follows:\n\n[source,java]\n----\nChatMemory chatMemory = MessageWindowChatMemory.builder().build();\n\nChatClient chatClient = ChatClient.builder(chatModel)\n    .defaultAdvisors(MessageChatMemoryAdvisor.builder(chatMemory).build())\n    .build();\n----\n\nWhen performing a call to the `ChatClient`, the memory will be automatically managed by the `MessageChatMemoryAdvisor`. The conversation history will be retrieved from the memory based on the specified conversation ID:\n\n[source,java]\n----\nString conversationId = \"007\";\n\nchatClient.prompt()\n    .user(\"Do I have license to code?\")\n    .advisors(a -> a.param(ChatMemory.CONVERSATION_ID, conversationId))\n    .call()\n    .content();\n----\n\n=== PromptChatMemoryAdvisor\n\n==== Custom Template\n\nThe `PromptChatMemoryAdvisor` uses a default template to augment the system message with the retrieved conversation memory. You can customize this behavior by providing your own `PromptTemplate` object via the `.promptTemplate()` builder method.\n\nNOTE: The `PromptTemplate` provided here customizes how the advisor merges retrieved memory with the system message. This is distinct from configuring a `TemplateRenderer` on the `ChatClient` itself (using `.templateRenderer()`), which affects the rendering of the initial user/system prompt content *before* the advisor runs. See xref:api/chatclient.adoc#_prompt_templates[ChatClient Prompt Templates] for more details on client-level template rendering.\n\nThe custom `PromptTemplate` can use any `TemplateRenderer` implementation (by default, it uses `StPromptTemplate` based on the https://www.stringtemplate.org/[StringTemplate] engine). The important requirement is that the template must contain the following two placeholders:\n\n* an `instructions` placeholder to receive the original system message.\n* a `memory` placeholder to receive the retrieved conversation memory.\n\n=== VectorStoreChatMemoryAdvisor\n\n==== Custom Template\n\nThe `VectorStoreChatMemoryAdvisor` uses a default template to augment the system message with the retrieved conversation memory. You can customize this behavior by providing your own `PromptTemplate` object via the `.promptTemplate()` builder method.\n\nNOTE: The `PromptTemplate` provided here customizes how the advisor merges retrieved memory with the system message. This is distinct from configuring a `TemplateRenderer` on the `ChatClient` itself (using `.templateRenderer()`), which affects the rendering of the initial user/system prompt content *before* the advisor runs. See xref:api/chatclient.adoc#_prompt_templates[ChatClient Prompt Templates] for more details on client-level template rendering.\n\nThe custom `PromptTemplate` can use any `TemplateRenderer` implementation (by default, it uses `StPromptTemplate` based on the https://www.stringtemplate.org/[StringTemplate] engine). The important requirement is that the template must contain the following two placeholders:\n\n* an `instructions` placeholder to receive the original system message.\n* a `long_term_memory` placeholder to receive the retrieved conversation memory.\n\n== Memory in Chat Model\n\nIf you're working directly with a `ChatModel` instead of a `ChatClient`, you can manage the memory explicitly:\n\n[source,java]\n----\n// Create a memory instance\nChatMemory chatMemory = MessageWindowChatMemory.builder().build();\nString conversationId = \"007\";\n\n// First interaction\nUserMessage userMessage1 = new UserMessage(\"My name is James Bond\");\nchatMemory.add(conversationId, userMessage1);\nChatResponse response1 = chatModel.call(new Prompt(chatMemory.get(conversationId)));\nchatMemory.add(conversationId, response1.getResult().getOutput());\n\n// Second interaction\nUserMessage userMessage2 = new UserMessage(\"What is my name?\");\nchatMemory.add(conversationId, userMessage2);\nChatResponse response2 = chatModel.call(new Prompt(chatMemory.get(conversationId)));\nchatMemory.add(conversationId, response2.getResult().getOutput());\n\n// The response will contain \"James Bond\"\n----\n"

    "content": "[[ChatClient]]\n= Chat Client API\n\nThe `ChatClient` offers a fluent API for communicating with an AI Model.\nIt supports both a synchronous and streaming programming model.  \n\n[NOTE]\n====\nSee the xref:api/chatclient.adoc#_implementation_notes[Implementation Notes] at the bottom of this document related to the combined use of imperative and reactive programming models in `ChatClient`\n====\n\nThe fluent API has methods for building up the constituent parts of a xref:api/prompt.adoc#_prompt[Prompt] that is passed to the AI model as input.\nThe `Prompt` contains the instructional text to guide the AI model's output and behavior. From the API point of view, prompts consist of a collection of messages.\n\nThe AI model processes two main types of messages: user messages, which are direct inputs from the user, and system messages, which are generated by the system to guide the conversation.\n\nThese messages often contain placeholders that are substituted at runtime based on user input to customize the response of the AI model to the user input.\n\nThere are also Prompt options that can be specified, such as the name of the AI Model to use and the temperature setting that controls the randomness or creativity of the generated output.\n\n== Creating a ChatClient\n\nThe `ChatClient` is created using a `ChatClient.Builder` object.\nYou can obtain an autoconfigured `ChatClient.Builder` instance for any xref:api/chatmodel.adoc[ChatModel] Spring Boot autoconfiguration or create one programmatically.\n\n=== Using an autoconfigured ChatClient.Builder\n\nIn the most simple use case, Spring AI provides Spring Boot autoconfiguration, creating a prototype `ChatClient.Builder` bean for you to inject into your class.\nHere is a simple example of retrieving a `String` response to a simple user request.\n\n[source,java]\n----\n@RestController\nclass MyController {\n\n    private final ChatClient chatClient;\n\n    public MyController(ChatClient.Builder chatClientBuilder) {\n        this.chatClient = chatClientBuilder.build();\n    }\n\n    @GetMapping(\"/ai\")\n    String generation(String userInput) {\n        return this.chatClient.prompt()\n            .user(userInput)\n            .call()\n            .content();\n    }\n}\n----\n\nIn this simple example, the user input sets the contents of the user message.\nThe `call()` method sends a request to the AI model, and the `content()` method returns the AI model's response as a `String`.\n\n=== Working with Multiple Chat Models\n\nThere are several scenarios where you might need to work with multiple chat models in a single application:\n\n* Using different models for different types of tasks (e.g., a powerful model for complex reasoning and a faster, cheaper model for simpler tasks)\n* Implementing fallback mechanisms when one model service is unavailable\n* A/B testing different models or configurations\n* Providing users with a choice of models based on their preferences\n* Combining specialized models (one for code generation, another for creative content, etc.)\n\nBy default, Spring AI autoconfigures a single `ChatClient.Builder` bean.\nHowever, you may need to work with multiple chat models in your application.\nHere's how to handle this scenario:\n\nIn all cases, you need to disable the `ChatClient.Builder` autoconfiguration by setting the property `spring.ai.chat.client.enabled=false`.\n\nThis allows you to create multiple `ChatClient` instances manually.\n\n==== Multiple ChatClients with a Single Model Type\n\nThis section covers a common use case where you need to create multiple ChatClient instances that all use the same underlying model type but with different configurations.\n\n[source,java]\n----\n// Create ChatClient instances programmatically\nChatModel myChatModel = ... // already autoconfigured by Spring Boot\nChatClient chatClient = ChatClient.create(myChatModel);\n\n// Or use the builder for more control\nChatClient.Builder builder = ChatClient.builder(myChatModel);\nChatClient customChatClient = builder\n    .defaultSystemPrompt(\"You are a helpful assistant.\")\n    .build();\n----\n\n==== ChatClients for Different Model Types\n\nWhen working with multiple AI models, you can define separate `ChatClient` beans for each model:\n\n[source,java]\n----\nimport org.springframework.ai.chat.ChatClient;\nimport org.springframework.context.annotation.Bean;\nimport org.springframework.context.annotation.Configuration;\n\n@Configuration\npublic class ChatClientConfig {\n    \n    @Bean\n    public ChatClient openAiChatClient(OpenAiChatModel chatModel) {\n        return ChatClient.create(chatModel);\n    }\n    \n    @Bean\n    public ChatClient anthropicChatClient(AnthropicChatModel chatModel) {\n        return ChatClient.create(chatModel);\n    }\n}\n----\n\nYou can then inject these beans into your application components using the `@Qualifier` annotation:\n\n[source,java]\n----\n\n@Configuration\npublic class ChatClientExample {\n    \n    @Bean\n    CommandLineRunner cli(\n            @Qualifier(\"openAiChatClient\") ChatClient openAiChatClient,\n            @Qualifier(\"anthropicChatClient\") ChatClient anthropicChatClient) {\n        \n        return args -> {\n            var scanner = new Scanner(System.in);\n            ChatClient chat;\n            \n            // Model selection\n            System.out.println(\"\\nSelect your AI model:\");\n            System.out.println(\"1. OpenAI\");\n            System.out.println(\"2. Anthropic\");\n            System.out.print(\"Enter your choice (1 or 2): \");\n            \n            String choice = scanner.nextLine().trim();\n            \n            if (choice.equals(\"1\")) {\n                chat = openAiChatClient;\n                System.out.println(\"Using OpenAI model\");\n            } else {\n                chat = anthropicChatClient;\n                System.out.println(\"Using Anthropic model\");\n            }\n            \n            // Use the selected chat client\n            System.out.print(\"\\nEnter your question: \");\n            String input = scanner.nextLine();\n            String response = chat.prompt(input).call().content();\n            System.out.println(\"ASSISTANT: \" + response);\n            \n            scanner.close();\n        };\n    }\n}\n----\n\n==== Multiple OpenAI-Compatible API Endpoints\n\nThe `OpenAiApi` and `OpenAiChatModel` classes provide a `mutate()` method that allows you to create variations of existing instances with different properties.\nThis is particularly useful when you need to work with multiple OpenAI-compatible APIs.\n\n[source,java]\n----\n\n@Service\npublic class MultiModelService {\n    \n    private static final Logger logger = LoggerFactory.getLogger(MultiModelService.class);\n    \n    @Autowired\n    private OpenAiChatModel baseChatModel;\n    \n    @Autowired\n    private OpenAiApi baseOpenAiApi;\n    \n    public void multiClientFlow() {\n        try {\n            // Derive a new OpenAiApi for Groq (Llama3)\n            OpenAiApi groqApi = baseOpenAiApi.mutate()\n                .baseUrl(\"https://api.groq.com/openai\")\n                .apiKey(System.getenv(\"GROQ_API_KEY\"))\n                .build();\n            \n            // Derive a new OpenAiApi for OpenAI GPT-4\n            OpenAiApi gpt4Api = baseOpenAiApi.mutate()\n                .baseUrl(\"https://api.openai.com\")\n                .apiKey(System.getenv(\"OPENAI_API_KEY\"))\n                .build();\n            \n            // Derive a new OpenAiChatModel for Groq\n            OpenAiChatModel groqModel = baseChatModel.mutate()\n                .openAiApi(groqApi)\n                .defaultOptions(OpenAiChatOptions.builder().model(\"llama3-70b-8192\").temperature(0.5).build())\n                .build();\n            \n            // Derive a new OpenAiChatModel for GPT-4\n            OpenAiChatModel gpt4Model = baseChatModel.mutate()\n                .openAiApi(gpt4Api)\n                .defaultOptions(OpenAiChatOptions.builder().model(\"gpt-4\").temperature(0.7).build())\n                .build();\n            \n            // Simple prompt for both models\n            String prompt = \"What is the capital of France?\";\n            \n            String groqResponse = ChatClient.builder(groqModel).build().prompt(prompt).call().content();\n            String gpt4Response = ChatClient.builder(gpt4Model).build().prompt(prompt).call().content();\n            \n            logger.info(\"Groq (Llama3) response: {}\", groqResponse);\n            logger.info(\"OpenAI GPT-4 response: {}\", gpt4Response);\n        }\n        catch (Exception e) {\n            logger.error(\"Error in multi-client flow\", e);\n        }\n    }\n}\n----\n\n\n== ChatClient Fluent API\n\nThe `ChatClient` fluent API allows you to create a prompt in three distinct ways using an overloaded `prompt` method to initiate the fluent API:\n\n* `prompt()`: This method with no arguments lets you start using the fluent API, allowing you to build up user, system, and other parts of the prompt.\n\n* `prompt(Prompt prompt)`: This method accepts a `Prompt` argument, letting you pass in a `Prompt` instance that you have created using the Prompt's non-fluent APIs.\n\n* `prompt(String content)`: This is a convenience method similar to the previous overload. It takes the user's text content.\n\n== ChatClient Responses\n\nThe `ChatClient` API offers several ways to format the response from the AI Model using the fluent API.\n\n=== Returning a ChatResponse\n\nThe response from the AI model is a rich structure defined by the type `xref:api/chatmodel.adoc#ChatResponse[ChatResponse]`.\nIt includes metadata about how the response was generated and can also contain multiple responses, known as xref:api/chatmodel.adoc#Generation[Generation]s, each with its own metadata.\nThe metadata includes the number of tokens (each token is approximately 3/4 of a word) used to create the response.\nThis information is important because hosted AI models charge based on the number of tokens used per request.\n\nAn example to return the `ChatResponse` object that contains the metadata is shown below by invoking `chatResponse()` after the `call()` method.\n\n[source,java]\n----\nChatResponse chatResponse = chatClient.prompt()\n    .user(\"Tell me a joke\")\n    .call()\n    .chatResponse();\n----\n\n\n=== Returning an Entity\n\nYou often want to return an entity class that is mapped from the returned `String`.\nThe `entity()` method provides this functionality.\n\nFor example, given the Java record:\n\n[source,java]\n----\nrecord ActorFilms(String actor, List<String> movies) {}\n----\n\nYou can easily map the AI model's output to this record using the `entity()` method, as shown below:\n\n[source,java]\n----\nActorFilms actorFilms = chatClient.prompt()\n    .user(\"Generate the filmography for a random actor.\")\n    .call()\n    .entity(ActorFilms.class);\n----\n\nThere is also an overloaded `entity` method with the signature `entity(ParameterizedTypeReference<T> type)` that lets you specify types such as generic Lists:\n\n[source,java]\n----\nList<ActorFilms> actorFilms = chatClient.prompt()\n    .user(\"Generate the filmography of 5 movies for Tom Hanks and Bill Murray.\")\n    .call()\n    .entity(new ParameterizedTypeReference<List<ActorFilms>>() {});\n----\n\n==== Native Structured Output\n\nAs more AI models support structured output natively, you can take advantage of this feature by using the `AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT` advisor parameter when calling the `ChatClient`.\nYou can use the `defaultAdvisors()` method on the `ChatClient.Builder` to set this parameter globally for all calls or set it per call as shown below:\n\n[source,java]\n----\nActorFilms actorFilms = chatClient.prompt()\n    .advisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT)\n    .user(\"Generate the filmography for a random actor.\")\n    .call()\n    .entity(ActorFilms.class);\n----\n\nNOTE: Some AI models such as OpenAI don't support arrays of objects natively.\nIn such cases, you can use the Spring AI default structured output conversion.\n\n=== Streaming Responses\n\nThe `stream()` method lets you get an asynchronous response as shown below:\n\n[source,java]\n----\n\nFlux<String> output = chatClient.prompt()\n    .user(\"Tell me a joke\")\n    .stream()\n    .content();\n----\n\nYou can also stream the `ChatResponse` using the method `Flux<ChatResponse> chatResponse()`.\n\nIn the future, we will offer a convenience method that will let you return a Java entity with the reactive `stream()` method.\nIn the meantime, you should use the xref:api/structured-output-converter.adoc#StructuredOutputConverter[Structured Output Converter] to convert the aggregated response explicitly as shown below.\nThis also demonstrates the use of parameters in the fluent API that will be discussed in more detail in a later section of the documentation.\n\n[source,java]\n----\nvar converter = new BeanOutputConverter<>(new ParameterizedTypeReference<List<ActorsFilms>>() {});\n\nFlux<String> flux = this.chatClient.prompt()\n    .user(u -> u.text(\"\"\"\n                        Generate the filmography for a random actor.\n                        {format}\n                      \"\"\")\n            .param(\"format\", this.converter.getFormat()))\n    .stream()\n    .content();\n\nString content = this.flux.collectList().block().stream().collect(Collectors.joining());\n\nList<ActorsFilms> actorFilms = this.converter.convert(this.content);\n----\n\n== Prompt Templates\n\nThe `ChatClient` fluent API lets you provide user and system text as templates with variables that are replaced at runtime.\n\n[source,java]\n----\nString answer = ChatClient.create(chatModel).prompt()\n    .user(u -> u\n            .text(\"Tell me the names of 5 movies whose soundtrack was composed by {composer}\")\n            .param(\"composer\", \"John Williams\"))\n    .call()\n    .content();\n----\n\nInternally, the ChatClient uses the `PromptTemplate` class to handle the user and system text and replace the variables with the values provided at runtime relying on a given `TemplateRenderer` implementation.\nBy default, Spring AI uses the `StTemplateRenderer` implementation, which is based on the open-source https://www.stringtemplate.org/[StringTemplate] engine developed by Terence Parr.\n\nSpring AI also provides a `NoOpTemplateRenderer` for cases where no template processing is desired.\n\nNOTE: The `TemplateRenderer` configured directly on the `ChatClient` (via `.templateRenderer()`) applies only to the prompt content defined directly in the `ChatClient` builder chain (e.g., via `.user()`, `.system()`).\nIt does *not* affect templates used internally by xref:api/retrieval-augmented-generation.adoc#_questionansweradvisor[Advisors] like `QuestionAnswerAdvisor`, which have their own template customization mechanisms (see xref:api/retrieval-augmented-generation.adoc#_custom_template[Custom Advisor Templates]).\n\nIf you'd rather use a different template engine, you can provide a custom implementation of the `TemplateRenderer` interface directly to the ChatClient. You can also keep using the default `StTemplateRenderer`, but with a custom configuration.\n\nFor example, by default, template variables are identified by the `{}` syntax.\nIf you're planning to include JSON in your prompt, you might want to use a different syntax to avoid conflicts with JSON syntax. For example, you can use the `<` and `>` delimiters.\n\n[source,java]\n----\nString answer = ChatClient.create(chatModel).prompt()\n    .user(u -> u\n            .text(\"Tell me the names of 5 movies whose soundtrack was composed by <composer>\")\n            .param(\"composer\", \"John Williams\"))\n    .templateRenderer(StTemplateRenderer.builder().startDelimiterToken('<').endDelimiterToken('>').build())\n    .call()\n    .content();\n----\n\n== call() return values\n\nAfter specifying the `call()` method on `ChatClient`, there are a few different options for the response type.\n\n* `String content()`: returns the String content of the response\n* `ChatResponse chatResponse()`: returns the `ChatResponse` object that contains multiple generations and also metadata about the response, for example how many token were used to create the response.\n* `ChatClientResponse chatClientResponse()`: returns a `ChatClientResponse` object that contains the `ChatResponse` object and the ChatClient execution context, giving you access to additional data used during the execution of advisors (e.g. the relevant documents retrieved in a RAG flow).\n* `entity()` to return a Java type\n** `entity(ParameterizedTypeReference<T> type)`: used to return a `Collection` of entity types.\n** `entity(Class<T> type)`:  used to return a specific entity type.\n** `entity(StructuredOutputConverter<T> structuredOutputConverter)`: used to specify an instance of a `StructuredOutputConverter` to convert a `String` to an entity type.\n* `responseEntity()` to return both the `ChatResponse` and a Java type. This is useful when you need access to both the complete AI model response (with metadata and generations) and the structured output entity in a single call.\n** `responseEntity(Class<T> type)`: used to return a `ResponseEntity` containing both the complete `ChatResponse` object and a specific entity type.\n** `responseEntity(ParameterizedTypeReference<T> type)`: used to return a `ResponseEntity` containing both the complete `ChatResponse` object and a `Collection` of entity types.\n** `responseEntity(StructuredOutputConverter<T> structuredOutputConverter)`: used to return a `ResponseEntity` containing both the complete `ChatResponse` object and an entity converted using a specified `StructuredOutputConverter`.\n\nYou can also invoke the `stream()` method instead of `call()`.\n\nNOTE: Calling the `call()` method does not actually trigger the AI model execution. Instead, it only instructs Spring AI whether to use synchronous or streaming calls.\nThe actual AI model invocation occurs when methods such as `content()`, `chatResponse()`, and `responseEntity()` are called.\n\n== stream() return values\n\nAfter specifying the `stream()` method on `ChatClient`, there are a few options for the response type:\n\n* `Flux<String> content()`: Returns a `Flux` of the string being generated by the AI model.\n* `Flux<ChatResponse> chatResponse()`: Returns a `Flux` of the `ChatResponse` object, which contains additional metadata about the response.\n* `Flux<ChatClientResponse> chatClientResponse()`: returns a `Flux` of the `ChatClientResponse` object that contains the `ChatResponse` object and the ChatClient execution context, giving you access to additional data used during the execution of advisors (e.g. the relevant documents retrieved in a RAG flow).\n\n== Message Metadata\n\nThe ChatClient supports adding metadata to both user and system messages.\nMetadata provides additional context and information about messages that can be used by the AI model or downstream processing.\n\n=== Adding Metadata to User Messages\n\nYou can add metadata to user messages using the `metadata()` methods:\n\n[source,java]\n----\n// Adding individual metadata key-value pairs\nString response = chatClient.prompt()\n    .user(u -> u.text(\"What's the weather like?\")\n        .metadata(\"messageId\", \"msg-123\")\n        .metadata(\"userId\", \"user-456\")\n        .metadata(\"priority\", \"high\"))\n    .call()\n    .content();\n\n// Adding multiple metadata entries at once\nMap<String, Object> userMetadata = Map.of(\n    \"messageId\", \"msg-123\",\n    \"userId\", \"user-456\",\n    \"timestamp\", System.currentTimeMillis()\n);\n\nString response = chatClient.prompt()\n    .user(u -> u.text(\"What's the weather like?\")\n        .metadata(userMetadata))\n    .call()\n    .content();\n----\n\n=== Adding Metadata to System Messages\n\nSimilarly, you can add metadata to system messages:\n\n[source,java]\n----\n// Adding metadata to system messages\nString response = chatClient.prompt()\n    .system(s -> s.text(\"You are a helpful assistant.\")\n        .metadata(\"version\", \"1.0\")\n        .metadata(\"model\", \"gpt-4\"))\n    .user(\"Tell me a joke\")\n    .call()\n    .content();\n----\n\n=== Default Metadata Support\n\nYou can also configure default metadata at the ChatClient builder level:\n\n[source,java]\n----\n@Configuration\nclass Config {\n    @Bean\n    ChatClient chatClient(ChatClient.Builder builder) {\n        return builder\n            .defaultSystem(s -> s.text(\"You are a helpful assistant\")\n                .metadata(\"assistantType\", \"general\")\n                .metadata(\"version\", \"1.0\"))\n            .defaultUser(u -> u.text(\"Default user context\")\n                .metadata(\"sessionId\", \"default-session\"))\n            .build();\n    }\n}\n----\n\n=== Metadata Validation\n\nThe ChatClient validates metadata to ensure data integrity:\n\n* Metadata keys cannot be null or empty\n* Metadata values cannot be null\n* When passing a Map, neither keys nor values can contain null elements\n\n[source,java]\n----\n// This will throw an IllegalArgumentException\nchatClient.prompt()\n    .user(u -> u.text(\"Hello\")\n        .metadata(null, \"value\"))  // Invalid: null key\n    .call()\n    .content();\n\n// This will also throw an IllegalArgumentException\nchatClient.prompt()\n    .user(u -> u.text(\"Hello\")\n        .metadata(\"key\", null))    // Invalid: null value\n    .call()\n    .content();\n----\n\n=== Accessing Metadata\n\nThe metadata is included in the generated UserMessage and SystemMessage objects and can be accessed through the message's `getMetadata()` method.\nThis is particularly useful when processing messages in advisors or when examining the conversation history.\n\n== Using Defaults\n\nCreating a `ChatClient` with a default system text in an `@Configuration` class simplifies runtime code.\nBy setting defaults, you only need to specify the user text when calling `ChatClient`, eliminating the need to set a system text for each request in your runtime code path.\n\n=== Default System Text\n\nIn the following example, we will configure the system text to always reply in a pirate's voice.\nTo avoid repeating the system text in runtime code, we will create a `ChatClient` instance in a `@Configuration` class.\n\n[source,java]\n----\n@Configuration\nclass Config {\n\n    @Bean\n    ChatClient chatClient(ChatClient.Builder builder) {\n        return builder.defaultSystem(\"You are a friendly chat bot that answers question in the voice of a Pirate\")\n                .build();\n    }\n\n}\n----\n\nand a `@RestController` to invoke it:\n\n[source,java]\n----\n@RestController\nclass AIController {\n\n\tprivate final ChatClient chatClient;\n\n\tAIController(ChatClient chatClient) {\n\t\tthis.chatClient = chatClient;\n\t}\n\n\t@GetMapping(\"/ai/simple\")\n\tpublic Map<String, String> completion(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n\t\treturn Map.of(\"completion\", this.chatClient.prompt().user(message).call().content());\n\t}\n}\n----\n\nWhen calling the application endpoint via curl, the result is:\n\n[source,bash]\n----\n❯ curl localhost:8080/ai/simple\n{\"completion\":\"Why did the pirate go to the comedy club? To hear some arrr-rated jokes! Arrr, matey!\"}\n----\n\n=== Default System Text with parameters\n\nIn the following example, we will use a placeholder in the system text to specify the voice of the completion at runtime instead of design time.\n\n[source,java]\n----\n@Configuration\nclass Config {\n\n    @Bean\n    ChatClient chatClient(ChatClient.Builder builder) {\n        return builder.defaultSystem(\"You are a friendly chat bot that answers question in the voice of a {voice}\")\n                .build();\n    }\n\n}\n----\n\n[source,java]\n----\n@RestController\nclass AIController {\n\tprivate final ChatClient chatClient;\n\n\tAIController(ChatClient chatClient) {\n\t\tthis.chatClient = chatClient;\n\t}\n\n\t@GetMapping(\"/ai\")\n\tMap<String, String> completion(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message, String voice) {\n\t\treturn Map.of(\"completion\",\n\t\t\t\tthis.chatClient.prompt()\n\t\t\t\t\t\t.system(sp -> sp.param(\"voice\", voice))\n\t\t\t\t\t\t.user(message)\n\t\t\t\t\t\t.call()\n\t\t\t\t\t\t.content());\n\t}\n\n}\n----\n\nWhen calling the application endpoint via httpie, the result is:\n\n[source.bash]\n----\nhttp localhost:8080/ai voice=='Robert DeNiro'\n{\n    \"completion\": \"You talkin' to me? Okay, here's a joke for ya: Why couldn't the bicycle stand up by itself? Because it was two tired! Classic, right?\"\n}\n----\n\n=== Other defaults\n\nAt the `ChatClient.Builder` level, you can specify the default prompt configuration.\n\n* `defaultOptions(ChatOptions chatOptions)`: Pass in either portable options defined in the `ChatOptions` class or model-specific options such as those in `OpenAiChatOptions`.\nFor more information on model-specific `ChatOptions` implementations, refer to the JavaDocs.\n\n* `defaultFunction(String name, String description, java.util.function.Function<I, O> function)`: The `name` is used to refer to the function in user text.\nThe `description` explains the function's purpose and helps the AI model choose the correct function for an accurate response.\nThe `function` argument is a Java function instance that the model will execute when necessary.\n\n* `defaultFunctions(String... functionNames)`: The bean names of `java.util.Function`s defined in the application context.\n\n* `defaultUser(String text)`, `defaultUser(Resource text)`, `defaultUser(Consumer<UserSpec> userSpecConsumer)`: These methods let you define the user text.\nThe `Consumer<UserSpec>` allows you to use a lambda to specify the user text and any default parameters.\n\n* `defaultAdvisors(Advisor... advisor)`: Advisors allow modification of the data used to create the `Prompt`.\nThe `QuestionAnswerAdvisor` implementation enables the pattern of `Retrieval Augmented Generation` by appending the prompt with context information related to the user text.\n\n* `defaultAdvisors(Consumer<AdvisorSpec> advisorSpecConsumer)`: This method allows you to define a `Consumer` to configure multiple advisors using the `AdvisorSpec`. Advisors can modify the data used to create the final `Prompt`.\nThe `Consumer<AdvisorSpec>` lets you specify a lambda to add advisors, such as `QuestionAnswerAdvisor`, which supports `Retrieval Augmented Generation` by appending the prompt with relevant context information based on the user text.\n\nYou can override these defaults at runtime using the corresponding methods without the `default` prefix.\n\n* `options(ChatOptions.Builder optionsCustomizer)`\n\n* `function(String name, String description,\njava.util.function.Function<I, O> function)`\n\n* `functions(String... functionNames)`\n\n* `user(String text)`, `user(Resource text)`, `user(Consumer<UserSpec> userSpecConsumer)`\n\n* `advisors(Advisor... advisor)`\n\n* `advisors(Consumer<AdvisorSpec> advisorSpecConsumer)`\n\nimage::chat-client-options-merging.png[align=\"center\"]\n\n== Advisors\n\nThe xref:api/advisors.adoc[Advisors API] provides a flexible and powerful way to intercept, modify, and enhance AI-driven interactions in your Spring applications. \n\nA common pattern when calling an AI model with user text is to append or augment the prompt with contextual data.\n\nThis contextual data can be of different types. Common types include:\n\n* **Your own data**: This is data the AI model hasn't been trained on.\nEven if the model has seen similar data, the appended contextual data takes precedence in generating the response.\n\n* **Conversational history**: The chat model's API is stateless.\nIf you tell the AI model your name, it won't remember it in subsequent interactions.\nConversational history must be sent with each request to ensure previous interactions are considered when generating a response.\n\n\n=== Advisor Configuration in ChatClient\n\nThe ChatClient fluent API provides an `AdvisorSpec` interface for configuring advisors.\nThis interface offers methods to add parameters, set multiple parameters at once, and add one or more advisors to the chain.\n\n[source,java]\n----\ninterface AdvisorSpec {\n    AdvisorSpec param(String k, Object v);\n    AdvisorSpec params(Map<String, Object> p);\n    AdvisorSpec advisors(Advisor... advisors);\n    AdvisorSpec advisors(List<Advisor> advisors);\n}\n----\n\nIMPORTANT: The order in which advisors are added to the chain is crucial, as it determines the sequence of their execution.\nEach advisor modifies the prompt or the context in some way, and the changes made by one advisor are passed on to the next in the chain.\n\n[source,java]\n----\nChatClient.builder(chatModel)\n    .build()\n    .prompt()\n    .advisors(\n        MessageChatMemoryAdvisor.builder(chatMemory).build(),\n        QuestionAnswerAdvisor.builder(vectorStore).build()\n    )\n    .user(userText)\n    .call()\n    .content();\n----\n\nIn this configuration, the `MessageChatMemoryAdvisor` will be executed first, adding the conversation history to the prompt.\nThen, the `QuestionAnswerAdvisor` will perform its search based on the user's question and the added conversation history, potentially providing more relevant results.\n\nxref:ROOT:api/retrieval-augmented-generation.adoc#_questionansweradvisor[Learn about Question Answer Advisor]\n\n=== Retrieval Augmented Generation\n\nRefer to the xref:ROOT:api/retrieval-augmented-generation.adoc[Retrieval Augmented Generation] guide.\n\n=== Logging\n\nThe `SimpleLoggerAdvisor` is an advisor that logs the `request` and `response` data of the `ChatClient`.\nThis can be useful for debugging and monitoring your AI interactions.\n\nTIP: Spring AI supports observability for LLM and vector store interactions.\nRefer to the xref:observability/index.adoc[Observability] guide for more information.\n\nTo enable logging, add the `SimpleLoggerAdvisor` to the advisor chain when creating your ChatClient.\nIt's recommended to add it toward the end of the chain:\n\n[source,java]\n----\nChatResponse response = ChatClient.create(chatModel).prompt()\n        .advisors(new SimpleLoggerAdvisor())\n        .user(\"Tell me a joke?\")\n        .call()\n        .chatResponse();\n----\n\nTo see the logs, set the logging level for the advisor package to `DEBUG`:\n\n----\nlogging.level.org.springframework.ai.chat.client.advisor=DEBUG\n----\n\nAdd this to your `application.properties` or `application.yaml` file.\n\nYou can customize what data from `AdvisedRequest` and `ChatResponse` is logged by using the following constructor:\n\n[source,java]\n----\nSimpleLoggerAdvisor(\n    Function<ChatClientRequest, String> requestToString,\n    Function<ChatResponse, String> responseToString,\n    int order\n)\n----\n\nExample usage:\n\n[source,java]\n----\nSimpleLoggerAdvisor customLogger = new SimpleLoggerAdvisor(\n    request -> \"Custom request: \" + request.prompt().getUserMessage(),\n    response -> \"Custom response: \" + response.getResult(),\n    0\n);\n----\n\nThis allows you to tailor the logged information to your specific needs.\n\nTIP: Be cautious about logging sensitive information in production environments.\n\n== Chat Memory\n\nThe interface `ChatMemory` represents a storage for chat conversation memory.\nIt provides methods to add messages to a conversation, retrieve messages from a conversation, and clear the conversation history.\n\nThere is currently one built-in implementation: `MessageWindowChatMemory`.\n\n`MessageWindowChatMemory` is a chat memory implementation that maintains a window of messages up to a specified maximum size (default: 20 messages).\nWhen the number of messages exceeds this limit, older messages are evicted, but system messages are preserved.\nIf a new system message is added, all previous system messages are removed from memory.\nThis ensures that the most recent context is always available for the conversation while keeping memory usage bounded.\n\nThe `MessageWindowChatMemory` is backed by the `ChatMemoryRepository` abstraction which provides storage implementations for the chat conversation memory.\nThere are several implementations available, including the `InMemoryChatMemoryRepository`, `JdbcChatMemoryRepository`, `CassandraChatMemoryRepository`, `Neo4jChatMemoryRepository`, `CosmosDBChatMemoryRepository`, `MongoChatMemoryRepository`, and `RedisChatMemoryRepository`.\n\nFor more details and usage examples, see the xref:api/chat-memory.adoc[Chat Memory] documentation.\n\n== Implementation Notes\n\nThe combined use of imperative and reactive programming models in `ChatClient` is a unique aspect of the API.\nOften an application will be either reactive or imperative, but not both.\n\n\n* When customizing the HTTP client interactions of a Model implementation, both the RestClient and the WebClient must be configured. \n\n[IMPORTANT]\n====\nDue to a bug in Spring Boot 3.4, the \"spring.http.client.factory=jdk\" property must be set.\nOtherwise, it's set to \"reactor\" by default, which breaks certain AI workflows like the ImageModel.\n====\n\n* Streaming is only supported via the Reactive stack.\nImperative applications must include the Reactive stack for this reason (e.g. spring-boot-starter-webflux).\n* Non-streaming is only supportive via the Servlet stack.\nReactive applications must include the Servlet stack for this reason (e.g. spring-boot-starter-web) and expect some calls to be blocking.\n* Tool calling is imperative, leading to blocking workflows.\nThis also results in partial/interrupted Micrometer observations (e.g. the ChatClient spans and the tool calling spans are not connected, with the first one remaining incomplete for that reason).\n* The built-in advisors perform blocking operations for standards calls, and non-blocking operations for streaming calls.\nThe Reactor Scheduler used for the advisor streaming calls can be configured via the Builder on each Advisor class.\n"

    "content": "[[ChatModel]]\n= Chat Model API\n\nThe Chat Model API offers developers the ability to integrate AI-powered chat completion capabilities into their applications. It leverages pre-trained language models, such as GPT (Generative Pre-trained Transformer), to generate human-like responses to user inputs in natural language.\n\nThe API typically works by sending a prompt or partial conversation to the AI model, which then generates a completion or continuation of the conversation based on its training data and understanding of natural language patterns. The completed response is then returned to the application, which can present it to the user or use it for further processing.\n\nThe `Spring AI Chat Model API` is designed to be a simple and portable interface for interacting with various xref:concepts.adoc#_models[AI Models], allowing developers to switch between different models with minimal code changes.\nThis design aligns with Spring's philosophy of modularity and interchangeability.\n\nAlso with the help of companion classes like `Prompt` for input encapsulation and `ChatResponse` for output handling, the Chat Model API unifies the communication with AI Models.\nIt manages the complexity of request preparation and response parsing, offering a direct and simplified API interaction.\n\nYou can find more about available implementations in the xref:api/chatmodel.adoc#_available_implementations[Available Implementations] section as well as detailed comparison in the xref:api/chat/comparison.adoc[Chat Models Comparison] section.\n\n== API Overview\n\nThis section provides a guide to the Spring AI Chat Model API interface and associated classes.\n\n=== ChatModel\n\nHere is the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/model/ChatModel.java[ChatModel] interface definition:\n\n[source,java]\n----\npublic interface ChatModel extends Model<Prompt, ChatResponse>, StreamingChatModel {\n\n\tdefault String call(String message) {...}\n\n    @Override\n\tChatResponse call(Prompt prompt);\n}\n\n----\n\nThe `call()` method with a `String` parameter simplifies initial use, avoiding the complexities of the more sophisticated `Prompt` and `ChatResponse` classes.\nIn real-world applications, it is more common to use the `call()` method that takes a `Prompt` instance and returns a `ChatResponse`.\n\n=== StreamingChatModel\n\nHere is the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/model/StreamingChatModel.java[StreamingChatModel] interface definition:\n\n[source,java]\n----\npublic interface StreamingChatModel extends StreamingModel<Prompt, ChatResponse> {\n\n    default Flux<String> stream(String message) {...}\n\n    @Override\n\tFlux<ChatResponse> stream(Prompt prompt);\n}\n----\n\nThe `stream()` method takes a `String` or `Prompt` parameter similar to `ChatModel` but it streams the responses using the reactive Flux API.\n\n=== Prompt\n\nThe https://github.com/spring-projects/spring-ai/blob/main/spring-ai-client-chat/src/main/java/org/springframework/ai/chat/prompt/Prompt.java[Prompt] is a `ModelRequest` that encapsulates a list of https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/messages/Message.java[Message] objects and optional model request options.\nThe following listing shows a truncated version of the `Prompt` class, excluding constructors and other utility methods:\n\n[source,java]\n----\npublic class Prompt implements ModelRequest<List<Message>> {\n\n    private final List<Message> messages;\n\n    private ChatOptions modelOptions;\n\n\t@Override\n\tpublic ChatOptions getOptions() {...}\n\n\t@Override\n\tpublic List<Message> getInstructions() {...}\n\n    // constructors and utility methods omitted\n}\n----\n\n==== Message\n\nThe `Message` interface encapsulates a `Prompt` textual content, a collection of metadata attributes, and a categorization known as `MessageType`.\n\nThe interface is defined as follows:\n\n[source,java]\n----\npublic interface Content {\n\n\tString getText();\n\n\tMap<String, Object> getMetadata();\n}\n\npublic interface Message extends Content {\n\n\tMessageType getMessageType();\n}\n----\n\nThe multimodal message types implement also the `MediaContent` interface providing a list of `Media` content objects.\n\n[source,java]\n----\npublic interface MediaContent extends Content {\n\n\tCollection<Media> getMedia();\n\n}\n----\n\nThe `Message` interface has various implementations that correspond to the categories of messages that an AI model can process:\n\nimage::spring-ai-message-api.jpg[Spring AI Message API, width=800, align=\"center\"]\n\nThe chat completion endpoint, distinguish between message categories based on conversational roles, effectively mapped by the `MessageType`.\n\nFor instance, OpenAI recognizes message categories for distinct conversational roles such as `system`, `user`, `function`, or `assistant`.\n\nWhile the term `MessageType` might imply a specific message format, in this context it effectively designates the role a message plays in the dialogue.\n\nFor AI models that do not use specific roles, the `UserMessage` implementation acts as a standard category, typically representing user-generated inquiries or instructions.\nTo understand the practical application and the relationship between `Prompt` and `Message`, especially in the context of these roles or message categories, see the detailed explanations in the xref:api/prompt.adoc[Prompts] section.\n\n==== Chat Options\n\nRepresents the options that can be passed to the AI model. The `ChatOptions` class is a subclass of `ModelOptions` and is used to define few portable options that can be passed to the AI model.\nThe `ChatOptions` class is defined as follows:\n\n[source,java]\n----\npublic interface ChatOptions extends ModelOptions {\n\n\tString getModel();\n\tFloat getFrequencyPenalty();\n\tInteger getMaxTokens();\n\tFloat getPresencePenalty();\n\tList<String> getStopSequences();\n\tFloat getTemperature();\n\tInteger getTopK();\n\tFloat getTopP();\n\tChatOptions copy();\n\n}\n----\n\nAdditionally, every model specific ChatModel/StreamingChatModel implementation can have its own options that can be passed to the AI model. For example, the OpenAI Chat Completion model has its own options like `logitBias`, `seed`, and `user`.\n\nSpring AI provides a sophisticated system for configuring and using Chat Models. \nIt allows for default configuration to be set at start-up, while also providing the flexibility to override these settings on a per-request basis.\nThis approach enables developers to easily work with different AI models and adjust parameters as needed, all within a consistent interface provided by the Spring AI framework.\n\nWhen using `ChatModel.call() / ChatModel/stream()`, the passed prompt needs to contain a full set of options that will completely take precedence over options set in the model (or use `null` options in the `Prompt` to use the model's defaults).\n\nThe xref:api/chatclient.adoc[ChatClient] abstraction allows for an incremental approach where users can provide a \"delta\" customizer that\n\nFollowing flow diagram illustrates how Spring AI handles the configuration and execution of Chat Models:\n\nimage::chat-model-conversions.png[align=\"center\", width=\"800px\"]\n\n1. Start-up Configuration - The ChatModel/StreamingChatModel is initialized with \"Start-Up\" Chat Options.\nThese options are set during the ChatModel initialization and are meant to provide default configurations.\n2. Runtime Configuration - For each request, the Prompt can contain a Runtime Chat Options: These fully override the start-up options.\n3. Input Processing - The \"Convert Input\" step transforms the input instructions into native, model-specific formats.\n4. Output Processing - The \"Convert Output\" step transforms the model's response into a standardized `ChatResponse` format.\n\n[[ChatResponse]]\n=== ChatResponse\n\nThe structure of the `ChatResponse` class is as follows:\n\n[source,java]\n----\npublic class ChatResponse implements ModelResponse<Generation> {\n\n    private final ChatResponseMetadata chatResponseMetadata;\n\tprivate final List<Generation> generations;\n\n\t@Override\n\tpublic ChatResponseMetadata getMetadata() {...}\n\n    @Override\n\tpublic List<Generation> getResults() {...}\n\n    // other methods omitted\n}\n----\n\nThe https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/model/ChatResponse.java[ChatResponse] class holds the AI Model's output, with each `Generation` instance containing one of potentially multiple outputs resulting from a single prompt.\n\nThe `ChatResponse` class also carries a `ChatResponseMetadata` metadata about the AI Model's response.\n\n[[Generation]]\n=== Generation\n\nFinally, the https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/chat/model/Generation.java[Generation] class extends from the `ModelResult` to represent the model output (assistant message) and related metadata:\n\n[source,java]\n----\npublic class Generation implements ModelResult<AssistantMessage> {\n\n\tprivate final AssistantMessage assistantMessage;\n\tprivate ChatGenerationMetadata chatGenerationMetadata;\n\n\t@Override\n\tpublic AssistantMessage getOutput() {...}\n\n\t@Override\n\tpublic ChatGenerationMetadata getMetadata() {...}\n\n    // other methods omitted\n}\n----\n\n== Available Implementations\n\nThis diagram illustrates the unified interfaces, `ChatModel` and `StreamingChatModel`, are used for interacting with various AI chat models from different providers, allowing easy integration and switching between different AI services while maintaining a consistent API for the client application.\n\nimage::spring-ai-chat-completions-clients.jpg[align=\"center\", width=\"1000px\"]\n\n* xref:api/chat/openai-chat.adoc[OpenAI Chat Completion] (streaming, multi-modality & function-calling support)\n* xref:api/chat/azure-openai-chat.adoc[Microsoft Azure Open AI Chat Completion] (streaming & function-calling support)\n* xref:api/chat/ollama-chat.adoc[Ollama Chat Completion] (streaming, multi-modality & function-calling support)\n* xref:api/bedrock.adoc[Amazon Bedrock]\n* xref:api/chat/mistralai-chat.adoc[Mistral AI Chat Completion] (streaming & function-calling support)\n* xref:api/chat/anthropic-chat.adoc[Anthropic Chat Completion] (streaming & function-calling support)\n\nTIP: Find a detailed comparison of the available Chat Models in the xref:api/chat/comparison.adoc[Chat Models Comparison] section.\n\n== Chat Model API\n\nThe Spring AI Chat Model API is built on top of the Spring AI `Generic Model API` providing Chat specific abstractions and implementations.\nThis allows an easy integration and switching between different AI services while maintaining a consistent API for the client application.\nThe following class diagram illustrates the main classes and interfaces of the Spring AI Chat Model API.\n\nimage::spring-ai-chat-api.jpg[align=\"center\", width=\"1000px\"]\n\n// == Best Practices\n//\n// TBD\n//\n// == Troubleshooting\n//\n// TBD\n\n// == Related Resources\n//\n// TBD\n"

    "content": "[[effective-agents]]\n= Building Effective Agents\n\nIn a recent research publication, https://www.anthropic.com/research/building-effective-agents[Building Effective Agents], Anthropic shared valuable insights about building effective Large Language Model (LLM) agents. What makes this research particularly interesting is its emphasis on simplicity and composability over complex frameworks. Let's explore how these principles translate into practical implementations using https://docs.spring.io/spring-ai/reference/index.html[Spring AI].\n\nimage::https://raw.githubusercontent.com/spring-io/spring-io-static/refs/heads/main/blog/tzolov/spring-ai-agentic-systems.jpg[Agent Systems, width=350]\n\nWhile the pattern descriptions and diagrams are sourced from Anthropic's original publication, we'll focus on how to implement these patterns using Spring AI's features for model portability and structured output. We recommend reading the original paper first.\n\nThe https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns[agentic-patterns] directory in the spring-ai-examples repository contains all the code for the examples that follow.\n\n== Agentic Systems\n\nThe research publication makes an important architectural distinction between two types of agentic systems:\n\n. *Workflows*: Systems where LLMs and tools are orchestrated through predefined code paths (e.g., prescriptive systems)\n. *Agents*: Systems where LLMs dynamically direct their own processes and tool usage\n\nThe key insight is that while fully autonomous agents might seem appealing, workflows often provide better predictability and consistency for well-defined tasks. This aligns perfectly with enterprise requirements where reliability and maintainability are crucial.\n\nLet's examine how Spring AI implements these concepts through five fundamental patterns, each serving specific use cases:\n\n=== 1. https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns/chain-workflow[Chain Workflow]\n\nThe Chain Workflow pattern exemplifies the principle of breaking down complex tasks into simpler, more manageable steps.\n\nimage::https://www.anthropic.com/_next/image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2F7418719e3dab222dccb379b8879e1dc08ad34c78-2401x1000.png&w=3840&q=75[Prompt Chaining Workflow]\n\n*When to Use:*\n- Tasks with clear sequential steps\n- When you want to trade latency for higher accuracy\n- When each step builds on the previous step's output\n\nHere's a practical example from Spring AI's implementation:\n\n[source,java]\n----\npublic class ChainWorkflow {\n    private final ChatClient chatClient;\n    private final String[] systemPrompts;\n\n    public String chain(String userInput) {\n        String response = userInput;\n        for (String prompt : systemPrompts) {\n            String input = String.format(\"{%s}\\n {%s}\", prompt, response);\n            response = chatClient.prompt(input).call().content();\n        }\n        return response;\n    }\n}\n----\n\nThis implementation demonstrates several key principles:\n\n- Each step has a focused responsibility\n- Output from one step becomes input for the next\n- The chain is easily extensible and maintainable\n\n=== 2. https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns/parallelization-workflow[Parallelization Workflow]\n\nLLMs can work simultaneously on tasks and have their outputs aggregated programmatically.\n\nimage::https://www.anthropic.com/_next/image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2F406bb032ca007fd1624f261af717d70e6ca86286-2401x1000.png&w=3840&q=75[Parallelization Workflow]\n\n*When to Use:*\n- Processing large volumes of similar but independent items\n- Tasks requiring multiple independent perspectives\n- When processing time is critical and tasks are parallelizable\n\n[source,java]\n----\nList<String> parallelResponse = new ParallelizationWorkflow(chatClient)\n    .parallel(\n        \"Analyze how market changes will impact this stakeholder group.\",\n        List.of(\n            \"Customers: ...\",\n            \"Employees: ...\",\n            \"Investors: ...\",\n            \"Suppliers: ...\"\n        ),\n        4\n    );\n----\n\n=== 3. https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns/routing-workflow[Routing Workflow]\n\nThe Routing pattern implements intelligent task distribution, enabling specialized handling for different types of input.\n\nimage::https://www.anthropic.com/_next/image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2F5c0c0e9fe4def0b584c04d37849941da55e5e71c-2401x1000.png&w=3840&q=75[Routing Workflow]\n\n*When to Use:*\n- Complex tasks with distinct categories of input\n- When different inputs require specialized processing\n- When classification can be handled accurately\n\n[source,java]\n----\n@Autowired\nprivate ChatClient chatClient;\n\nRoutingWorkflow workflow = new RoutingWorkflow(chatClient);\n\nMap<String, String> routes = Map.of(\n    \"billing\", \"You are a billing specialist. Help resolve billing issues...\",\n    \"technical\", \"You are a technical support engineer. Help solve technical problems...\",\n    \"general\", \"You are a customer service representative. Help with general inquiries...\"\n);\n\nString input = \"My account was charged twice last week\";\nString response = workflow.route(input, routes);\n----\n\n=== 4. https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns/orchestrator-workers[Orchestrator-Workers]\n\nimage::https://www.anthropic.com/_next/image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2F8985fc683fae4780fb34eab1365ab78c7e51bc8e-2401x1000.png&w=3840&q=75[Orchestration Workflow]\n\n*When to Use:*\n- Complex tasks where subtasks can't be predicted upfront\n- Tasks requiring different approaches or perspectives\n- Situations needing adaptive problem-solving\n\n[source,java]\n----\npublic class OrchestratorWorkersWorkflow {\n    public WorkerResponse process(String taskDescription) {\n        // 1.

    "content": "= Azure OpenAI Embeddings\n\nAzure's OpenAI extends the OpenAI capabilities, offering safe text generation and Embeddings computation models for various task:\n\n- Similarity embeddings are good at capturing semantic similarity between two or more pieces of text.\n- Text search embeddings help measure whether long documents are relevant to a short query.\n- Code search embeddings are useful for embedding code snippets and embedding natural language search queries.\n\nThe Azure OpenAI embeddings rely on `cosine similarity` to compute similarity between documents and a query.\n\n== Prerequisites\n\n\nThe Azure OpenAI client offers three options to connect: using an Azure API key or using an OpenAI API Key, or using Microsoft Entra ID.\n\n\n=== Azure API Key & Endpoint\n\nObtain your Azure OpenAI `endpoint` and `api-key` from the Azure OpenAI Service section on the https://portal.azure.com[Azure Portal].\n\nSpring AI defines two configuration properties:\n\n1. `spring.ai.azure.openai.api-key`: Set this to the value of the `API Key` obtained from Azure.\n2. `spring.ai.azure.openai.endpoint`: Set this to the endpoint URL obtained when provisioning your model in Azure.\n\nYou can set these configuration properties in your `application.properties` or `application.yml` file:\n\n[source,properties]\n----\nspring.ai.azure.openai.api-key=<your-azure-api-key>\nspring.ai.azure.openai.endpoint=<your-azure-endpoint-url>\n----\n\nIf you prefer to use environment variables for sensitive information like API keys, you can use Spring Expression Language (SpEL) in your configuration:\n\n[source,yaml]\n----\n# In application.yml\nspring:\n  ai:\n    azure:\n      openai:\n        api-key: ${AZURE_OPENAI_API_KEY}\n        endpoint: ${AZURE_OPENAI_ENDPOINT}\n----\n\n[source,bash]\n----\n# In your environment or .env file\nexport AZURE_OPENAI_API_KEY=<your-azure-openai-api-key>\nexport AZURE_OPENAI_ENDPOINT=<your-azure-endpoint-url>\n----\n\n=== OpenAI Key\n\nTo authenticate with the OpenAI service (not Azure), provide an OpenAI API key.\nThis will automatically set the endpoint to https://api.openai.com/v1.\n\nWhen using this approach, set the `spring.ai.azure.openai.chat.options.deployment-name` property to the name of the https://platform.openai.com/docs/models[OpenAI model] you wish to use.\n\nIn your application configuration:\n\n[source,properties]\n----\nspring.ai.azure.openai.openai-api-key=<your-azure-openai-key>\nspring.ai.azure.openai.chat.options.deployment-name=<openai-model-name>\n----\n\nUsing environment variables with SpEL:\n\n[source,yaml]\n----\n# In application.yml\nspring:\n  ai:\n    azure:\n      openai:\n        openai-api-key: ${AZURE_OPENAI_API_KEY}\n        chat:\n          options:\n            deployment-name: ${OPENAI_MODEL_NAME}\n----\n\n[source,bash]\n----\n# In your environment or .env file\nexport AZURE_OPENAI_API_KEY=<your-openai-key>\nexport OPENAI_MODEL_NAME=<openai-model-name>\n----\n=== Microsoft Entra ID\n\nFor keyless authentication using Microsoft Entra ID (formerly Azure Active Directory), set _only_ the `spring.ai.azure.openai.endpoint` configuration property and _not_ the api-key property mentioned above.\n\nFinding only the endpoint property, your application will evaluate several different options for retrieving credentials and an `OpenAIClient` instance will be created using the token credentials.\n\nNOTE: It is no longer necessary to create a `TokenCredential` bean; it is configured for you automatically.\n\n=== Add Repositories and BOM\n\nSpring AI artifacts are published in Maven Central and Spring Snapshot repositories.\nRefer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system.\n\nTo help with dependency management, Spring AI provides a BOM (bill of materials) to ensure that a consistent version of Spring AI is used throughout the entire project. Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build system.\n\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the Azure OpenAI Embedding Model.\nTo enable it add the following dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-azure-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-azure-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n=== Embedding Properties\n\nThe prefix `spring.ai.azure.openai` is the property prefix to configure the connection to Azure OpenAI.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.azure.openai.api-key |  The Key from Azure AI OpenAI `Keys and Endpoint` section under `Resource Management`  | -\n| spring.ai.azure.openai.endpoint | The endpoint from the Azure AI OpenAI `Keys and Endpoint` section under `Resource Management` | -\n| spring.ai.azure.openai.openai-api-key |  (non Azure) OpenAI API key. Used to authenticate with the OpenAI service, instead of Azure OpenAI. \nThis automatically sets the endpoint to https://api.openai.com/v1. Use either `api-key` or `openai-api-key` property. \nWith this configuration the `spring.ai.azure.openai.embedding.options.deployment-name` is treated as an https://platform.openai.com/docs/models[OpenAi Model] name.| -\n|====\n\n\n[NOTE]\n====\nEnabling and disabling of the embedding auto-configurations are now configured via top level properties with the prefix `spring.ai.model.embedding`.\n\nTo enable, spring.ai.model.embedding=azure-openai (It is enabled by default)\n\nTo disable, spring.ai.model.embedding=none (or any value which doesn't match azure-openai)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix `spring.ai.azure.openai.embedding` is the property prefix that configures the `EmbeddingModel` implementation for Azure OpenAI\n\n[cols=\"3,5,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| spring.ai.azure.openai.embedding.enabled (Removed and no longer valid) | Enable Azure OpenAI embedding model.  | true\n| spring.ai.model.embedding | Enable Azure OpenAI embedding model.  | azure-openai\n| spring.ai.azure.openai.embedding.metadata-mode | Document content extraction mode    | EMBED\n| spring.ai.azure.openai.embedding.options.deployment-name | This is the value of the 'Deployment Name' as presented in the Azure AI Portal | text-embedding-ada-002\n| spring.ai.azure.openai.embedding.options.user | An identifier for the caller or end user of the operation. This may be used for tracking or rate-limiting purposes. | -\n|====\n\nTIP: All properties prefixed with `spring.ai.azure.openai.embedding.options` can be overridden at runtime by adding a request specific <<embedding-options>> to the `EmbeddingRequest` call.\n\n== Runtime Options [[embedding-options]]\n\nThe `AzureOpenAiEmbeddingOptions` provides the configuration information for the embedding requests.\nThe `AzureOpenAiEmbeddingOptions` offers a builder to create the options.\n\nAt start time use the `AzureOpenAiEmbeddingModel` constructor to set the  default options used for all embedding requests.\nAt run-time you can override the default options, by passing a `AzureOpenAiEmbeddingOptions` instance with your to the  `EmbeddingRequest` request.\n\nFor example to override the default model name for a specific request:\n\n[source,java]\n----\nEmbeddingResponse embeddingResponse = embeddingModel.call(\n    new EmbeddingRequest(List.of(\"Hello World\", \"World is big and salvation is near\"),\n        AzureOpenAiEmbeddingOptions.builder()\n        .model(\"Different-Embedding-Model-Deployment-Name\")\n        .build()));\n----\n\n\n== Sample Code\n\nThis will create a `EmbeddingModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the `EmbeddingModel` implementation.\n\n[source,application.properties]\n----\nspring.ai.azure.openai.api-key=YOUR_API_KEY\nspring.ai.azure.openai.endpoint=YOUR_ENDPOINT\nspring.ai.azure.openai.embedding.options.model=text-embedding-ada-002\n----\n\n[source,java]\n----\n@RestController\npublic class EmbeddingController {\n\n    private final EmbeddingModel embeddingModel;\n\n    @Autowired\n    public EmbeddingController(EmbeddingModel embeddingModel) {\n        this.embeddingModel = embeddingModel;\n    }\n\n    @GetMapping(\"/ai/embedding\")\n    public Map embed(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        EmbeddingResponse embeddingResponse = this.embeddingModel.embedForResponse(List.of(message));\n        return Map.of(\"embedding\", embeddingResponse);\n    }\n}\n----\n\n== Manual Configuration\n\nIf you prefer not to use the Spring Boot auto-configuration, you can manually configure the `AzureOpenAiEmbeddingModel` in your application.\nFor this add the `spring-ai-azure-openai` dependency to your project's Maven `pom.xml` file:\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-azure-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,gradle]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-azure-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNOTE: The `spring-ai-azure-openai` dependency also provide the access to the `AzureOpenAiEmbeddingModel`. For more information about the `AzureOpenAiChatModel` refer to the link:../embeddings/azure-openai-embeddings.html[Azure OpenAI Embeddings] section.\n\nNext, create an `AzureOpenAiEmbeddingModel` instance and use it to compute the similarity between two input texts:\n\n[source,java]\n----\nvar openAIClient = OpenAIClientBuilder()\n        .credential(new AzureKeyCredential(System.getenv(\"AZURE_OPENAI_API_KEY\")))\n\t\t.endpoint(System.getenv(\"AZURE_OPENAI_ENDPOINT\"))\n\t\t.buildClient();\n\nvar embeddingModel = new AzureOpenAiEmbeddingModel(this.openAIClient)\n    .withDefaultOptions(AzureOpenAiEmbeddingOptions.builder()\n        .model(\"text-embedding-ada-002\")\n        .user(\"user-6\")\n        .build());\n\nEmbeddingResponse embeddingResponse = this.embeddingModel\n\t.embedForResponse(List.of(\"Hello World\", \"World is big and salvation is near\"));\n----\n\nNOTE: the `text-embedding-ada-002` is actually the `Deployment Name` as presented in the Azure AI Portal.\n\n"

options);\n\nEmbeddingResponse embeddingResponse = embeddingModel\n\t.embedForResponse(List.of(\"Hello World\", \"World is big and salvation is near\"));\n----\n\n== Task Types\n\nThe Google GenAI embeddings API supports different task types to optimize embeddings for specific use cases:\n\n- `RETRIEVAL_QUERY`: Optimized for search queries in retrieval systems\n- `RETRIEVAL_DOCUMENT`: Optimized for documents in retrieval systems\n- `SEMANTIC_SIMILARITY`: Optimized for measuring semantic similarity between texts\n- `CLASSIFICATION`: Optimized for text classification tasks\n- `CLUSTERING`: Optimized for clustering similar texts\n- `QUESTION_ANSWERING`: Optimized for question-answering systems\n- `FACT_VERIFICATION`: Optimized for fact verification tasks\n\nExample of using different task types:\n\n[source,java]\n----\n// For indexing documents\nGoogleGenAiTextEmbeddingOptions docOptions = GoogleGenAiTextEmbeddingOptions.builder()\n    .model(\"text-embedding-004\")\n    .taskType(TaskType.RETRIEVAL_DOCUMENT)\n    .title(\"Product Documentation\")  // Optional title for documents\n    .build();\n\n// For search queries\nGoogleGenAiTextEmbeddingOptions queryOptions = GoogleGenAiTextEmbeddingOptions.builder()\n    .model(\"text-embedding-004\")\n    .taskType(TaskType.RETRIEVAL_QUERY)\n    .build();\n----\n\n== Dimension Reduction\n\nFor model version 004 and later, you can reduce the embedding dimensions for storage optimization:\n\n[source,java]\n----\nGoogleGenAiTextEmbeddingOptions options = GoogleGenAiTextEmbeddingOptions.builder()\n    .model(\"text-embedding-004\")\n    .dimensions(256)  // Reduce from default 768 to 256 dimensions\n    .build();\n----\n\n== Migration from Vertex AI Text Embeddings\n\nIf you're currently using the Vertex AI Text Embeddings implementation (`spring-ai-vertex-ai-embedding`), you can migrate to Google GenAI with minimal changes:\n\nKey Differences:\n\n1. **SDK**: Google GenAI uses the new `com.google.genai.Client` instead of Vertex AI SDK\n2. **Authentication**: Supports both API key and Google Cloud credentials (Vertex AI mode)\n3. **Package Names**: Classes are in `org.springframework.ai.google.genai.text` instead of `org.springframework.ai.vertexai.embedding`\n4. **Property Prefix**: Uses `spring.ai.google.genai.embedding` instead of `spring.ai.vertex.ai.embedding`\n5. **Connection Details**: Uses `GoogleGenAiEmbeddingConnectionDetails` instead of `VertexAiEmbeddingConnectionDetails`\n\nGoogle GenAI supports both quick prototyping with API keys and production deployments using Vertex AI through Google Cloud credentials."

Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build system.\n\n\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the Azure MiniMax Embedding Model.\nTo enable it add the following dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-minimax</artifactId>\n</dependency>\n----\n\nor to your Gradle

spring.ai.model.embedding=minimax (It is enabled by default)\n\nTo disable, spring.ai.model.embedding=none (or any value which doesn't match minimax)\n\nThis change is done to allow configuration of multiple models.\n====\n\n\nThe prefix `spring.ai.minimax.embedding` is property prefix that configures the `EmbeddingModel` implementation for MiniMax.\n\n[cols=\"3,5,1\", stripes=even]\n|====\n|

can override the common `spring.ai.minimax.base-url` and `spring.ai.minimax.api-key` for the `ChatModel` and `EmbeddingModel` implementations.\nThe `spring.ai.minimax.embedding.base-url` and `spring.ai.minimax.embedding.api-key` properties if set take precedence over the common properties.\nSimilarly, the `spring.ai.minimax.chat.base-url` and `spring.ai.minimax.chat.api-key` properties if set take precedence over the common properties.\nThis is useful if you want to use different MiniMax accounts for different models and different model endpoints.\n\nTIP: All properties prefixed with `spring.ai.minimax.embedding.options` can be overridden at runtime by adding a request specific <<embedding-options>> to the `EmbeddingRequest` call.\n\n== Runtime Options [[embedding-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-minimax/src/main/java/org/springframework/ai/minimax/MiniMaxEmbeddingOptions.java[MiniMaxEmbeddingOptions.java] provides the MiniMax configurations, such as the model to use and etc.\n\nThe default options can be configured using the `spring.ai.minimax.embedding.options` properties as well.\n\nAt start-time use the `MiniMaxEmbeddingModel` constructor to set the  default options used for all embedding requests.\nAt run-time you can override the default options, using a `MiniMaxEmbeddingOptions` instance as part of your `EmbeddingRequest`.\n\nFor example to override the default model name for a specific request:\n\n[source,java]\n----\nEmbeddingResponse embeddingResponse = embeddingModel.call(\n    new EmbeddingRequest(List.of(\"Hello World\", \"World is big and salvation is near\"),\n        MiniMaxEmbeddingOptions.builder()\n            .model(\"Different-Embedding-Model-Deployment-Name\")\n        .build()));\n----\n\n== Sample Controller\n\nThis will create a `EmbeddingModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the `EmbeddingC` implementation.\n\n[source,application.properties]\n----\nspring.ai.minimax.api-key=YOUR_API_KEY\nspring.ai.minimax.embedding.options.model=embo-01\n----\n\n[source,java]\n----\n@RestController\npublic class EmbeddingController {\n\n    private final EmbeddingModel embeddingModel;\n\n    @Autowired\n    public EmbeddingController(EmbeddingModel embeddingModel) {\n        this.embeddingModel = embeddingModel;\n    }\n\n    @GetMapping(\"/ai/embedding\")\n    public Map embed(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        EmbeddingResponse embeddingResponse = this.embeddingModel.embedForResponse(List.of(message));\n        return Map.of(\"embedding\", embeddingResponse);\n    }\n}\n----\n\n== Manual Configuration\n\nIf you are not using Spring Boot, you can manually configure the MiniMax Embedding Model.\nFor this add the `spring-ai-minimax` dependency to your project's Maven `pom.xml` file:\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-minimax</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-minimax'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNOTE: The `spring-ai-minimax` dependency provides access also to the `MiniMaxChatModel`.\nFor more information about the `MiniMaxChatModel refer to the link:../chat/minimax-chat.html[MiniMax Chat Client] section.\n\nNext, create an `MiniMaxEmbeddingModel` instance and use it to compute the similarity between two input texts:\n\n[source,java]\n----\nvar miniMaxApi = new MiniMaxApi(System.getenv(\"MINIMAX_API_KEY\"));\n\nvar embeddingModel = new MiniMaxEmbeddingModel(minimaxApi, MetadataMode.EMBED,\nMiniMaxEmbeddingOptions.builder().model(\"embo-01\").build());\n\nEmbeddingResponse embeddingResponse = this.embeddingModel\n\t.embedForResponse(List.of(\"Hello World\", \"World is big and salvation is near\"));\n----\n\nThe `MiniMaxEmbeddingOptions` provides the configuration information for the embedding requests.\nThe options class offers a `builder()` for easy options creation.\n\n\n"

On macOS it defaults to 1 to enable metal support, 0 to disable. 1 here indicates that NumGPU should be set dynamically | -1\n| spring.ai.ollama.embedding.options.main-gpu          | When using multiple GPUs this option controls which GPU is used for small tensors for which the overhead of splitting the computation across all GPUs is not worthwhile. The GPU in question will use slightly more VRAM to store a scratch buffer for temporary results. | 0\n| spring.ai.ollama.embedding.options.low-vram          | -                                                             | false\n| spring.ai.ollama.embedding.options.f16-kv            | -                                                             | true\n| spring.ai.ollama.embedding.options.logits-all        | Return logits for all the tokens, not just the last one. To enable completions to return logprobs, this must be true. | -\n| spring.ai.ollama.embedding.options.vocab-only        | Load only the vocabulary, not the weights. | -\n| spring.ai.ollama.embedding.options.use-mmap          | By default, models are mapped into memory, which allows the system to load only the necessary parts of the model as needed. However, if the model is larger than your total amount of RAM or if your system is low on available memory, using mmap might increase the risk of pageouts, negatively impacting performance. Disabling mmap results in slower load times but may reduce pageouts if you're not using mlock. Note that if the model is larger than the total amount of RAM, turning off mmap would prevent the model from loading at all. | null\n| spring.ai.ollama.embedding.options.use-mlock         | Lock the model in memory, preventing it from being swapped out when memory-mapped. This can improve performance but trades away some of the advantages of memory-mapping by requiring more RAM to run and potentially slowing down load times as the model loads into RAM. | false\n| spring.ai.ollama.embedding.options.num-thread        | Sets the number of threads to use during computation. By default, Ollama will detect this for optimal performance. It is recommended to set this value to the number of physical CPU cores your system has (as opposed to the logical number of cores). 0 = let the runtime decide | 0\n| spring.ai.ollama.embedding.options.num-keep          | -                                                             | 4\n| spring.ai.ollama.embedding.options.seed              | Sets the random number seed to use for generation. Setting this to a specific number will make the model generate the same text for the same prompt.  | -1\n| spring.ai.ollama.embedding.options.num-predict       | Maximum number of tokens to predict when generating text. (-1 = infinite generation, -2 = fill context) | -1\n| spring.ai.ollama.embedding.options.top-k             | Reduces the probability of generating nonsense. A higher value (e.g., 100) will give more diverse answers, while a lower value (e.g., 10) will be more conservative.  | 40\n| spring.ai.ollama.embedding.options.top-p             | Works together with top-k. A higher value (e.g., 0.95) will lead to more diverse text, while a lower value (e.g., 0.5) will generate more focused and conservative text.  | 0.9\n| spring.ai.ollama.embedding.options.min-p             | Alternative to the top_p, and aims to ensure a balance of quality and variety. The parameter p represents the minimum probability for a token to be considered, relative to the probability of the most likely token. For example, with p=0.05 and the most likely token having a probability of 0.9, logits with a value less than 0.045 are filtered out.  | 0.0\n| spring.ai.ollama.embedding.options.tfs-z             | Tail-free sampling is used to reduce the impact of less probable tokens from the output. A higher value (e.g., 2.0) will reduce the impact more, while a value of 1.0 disables this setting. | 1.0\n| spring.ai.ollama.embedding.options.typical-p         | -                                                             | 1.0\n| spring.ai.ollama.embedding.options.repeat-last-n     | Sets how far back for the model to look back to prevent repetition. (Default: 64, 0 = disabled, -1 = num_ctx) | 64\n| spring.ai.ollama.embedding.options.temperature       | The temperature of the model. Increasing the temperature will make the model answer more creatively. | 0.8\n| spring.ai.ollama.embedding.options.repeat-penalty    | Sets how strongly to penalize repetitions. A higher value (e.g., 1.5) will penalize repetitions more strongly, while a lower value (e.g., 0.9) will be more lenient. | 1.1\n| spring.ai.ollama.embedding.options.presence-penalty  | -                                                             | 0.0\n| spring.ai.ollama.embedding.options.frequency-penalty | -                                                             | 0.0\n| spring.ai.ollama.embedding.options.mirostat          | Enable Mirostat sampling for controlling perplexity. (default: 0, 0 = disabled, 1 = Mirostat, 2 = Mirostat 2.0) | 0\n| spring.ai.ollama.embedding.options.mirostat-tau      | Controls the balance between coherence and diversity of the output. A lower value will result in more focused and coherent text. | 5.0\n| spring.ai.ollama.embedding.options.mirostat-eta      | Influences how quickly the algorithm responds to feedback from the generated text. A lower learning rate will result in slower adjustments, while a higher learning rate will make the algorithm more responsive. | 0.1\n| spring.ai.ollama.embedding.options.penalize-newline  | -                                                             | true\n| spring.ai.ollama.embedding.options.stop              | Sets the stop sequences to use. When this pattern is encountered the LLM will stop generating text and return. Multiple stop patterns may be set by specifying multiple separate stop parameters in a modelfile. | -\n| spring.ai.ollama.embedding.options.functions         | List of functions, identified by their names, to enable for function calling in a single prompt requests. Functions with those names must exist in the functionCallbacks registry. | -\n|====\n\nTIP: All properties prefixed with `spring.ai.ollama.embedding.options` can be overridden at runtime by adding a request specific <<embedding-options>> to the `EmbeddingRequest` call.\n\n== Runtime Options [[embedding-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-ollama/src/main/java/org/springframework/ai/ollama/api/OllamaEmbeddingOptions.java[OllamaEmbeddingOptions.java] provides the Ollama configurations, such as the model to use, the low level GPU and CPU tuning, etc.\n\nIMPORTANT: The `OllamaOptions` class has been deprecated. Use `OllamaChatOptions` for chat models and `OllamaEmbeddingOptions` for embedding models instead. The new classes provide type-safe, model-specific configuration options.\n\nThe default options can be configured using the `spring.ai.ollama.embedding.options` properties as well.\n\nAt start-time use the `OllamaEmbeddingModel(OllamaApi ollamaApi, OllamaEmbeddingOptions defaultOptions)` to configure the  default options used for all embedding requests.\nAt run-time you can override the default options, using a `OllamaEmbeddingOptions` instance as part of your `EmbeddingRequest`.\n\nFor example to override the default model name for a specific request:\n\n[source,java]\n----\nEmbeddingResponse embeddingResponse = embeddingModel.call(\n    new EmbeddingRequest(List.of(\"Hello World\", \"World is big and salvation is near\"),\n        OllamaEmbeddingOptions.builder()\n            .model(\"Different-Embedding-Model-Deployment-Name\"))\n            .truncates(false)\n            .build());\n----\n\n[[auto-pulling-models]]\n== Auto-pulling Models\n\nSpring AI Ollama can automatically pull models when they are not available in your Ollama instance.\nThis feature is particularly useful for development and testing as well as for deploying your applications to new environments.\n\nTIP: You can also pull, by name, any of the thousands, free, link:https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face Models].\n\nThere are three strategies for pulling models:\n\n* `always` (defined in `PullModelStrategy.ALWAYS`): Always pull the model, even if it's already available. Useful to ensure you're using the latest version of the model.\n* `when_missing` (defined in `PullModelStrategy.WHEN_MISSING`): Only pull the model if it's not already available. This may result in using an older version of the model.\n* `never` (defined in `PullModelStrategy.NEVER`): Never pull the model automatically.\n\nCAUTION: Due to potential delays while downloading models, automatic pulling is not recommended for production environments. Instead, consider assessing and pre-downloading the necessary models in advance.\n\nAll models defined via configuration properties and default options can be automatically pulled at startup time.\nYou can configure the pull strategy, timeout, and maximum number of retries using configuration properties:\n\n[source,yaml]\n----\nspring:\n  ai:\n    ollama:\n      init:\n        pull-model-strategy: always\n        timeout: 60s\n        max-retries: 1\n----\n\nCAUTION: The application will not complete its initialization until all specified models are available in Ollama. Depending on the model size and internet connection speed, this may significantly slow down your application's startup time.\n\nYou can initialize additional models at startup, which is useful for models used dynamically at runtime:\n\n[source,yaml]\n----\nspring:\n  ai:\n    ollama:\n      init:\n        pull-model-strategy: always\n        embedding:\n          additional-models:\n            - mxbai-embed-large\n            - nomic-embed-text\n----\n\nIf you want to apply the pulling strategy only to specific types of models, you can exclude embedding models from the initialization task:\n\n[source,yaml]\n----\nspring:\n  ai:\n    ollama:\n      init:\n        pull-model-strategy: always\n        embedding:\n          include: false\n----\n\nThis configuration will apply the pulling strategy to all models except embedding models.\n\n== HuggingFace Models\n\nOllama can access, out of the box, all https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face] Embedding models.\nYou can pull any of these models by name: `ollama pull hf.co/<username>/<model-repository>` or configure the auto-pulling strategy: xref:auto-pulling-models[Auto-pulling Models]:\n\n[source]\n----\nspring.ai.ollama.embedding.options.model=hf.co/mixedbread-ai/mxbai-embed-large-v1\nspring.ai.ollama.init.pull-model-strategy=always\n----\n\n- `spring.ai.ollama.embedding.options.model`: Specifies the https://huggingface.co/models?library=gguf&sort=trending[Hugging Face GGUF model] to use. \n- `spring.ai.ollama.init.pull-model-strategy=always`: (optional) Enables automatic model pulling at startup time. \nFor production, you should pre-download the models to avoid delays: `ollama pull hf.co/mixedbread-ai/mxbai-embed-large-v1`.\n\n== Sample Controller\n\nThis will create a `EmbeddingModel` implementation that you can inject into your class.\nHere is an example of a simple `@Controller` class that uses the `EmbeddingModel` implementation.\n\n[source,java]\n----\n@RestController\npublic class EmbeddingController {\n\n    private final EmbeddingModel embeddingModel;\n\n    @Autowired\n    public EmbeddingController(EmbeddingModel embeddingModel) {\n        this.embeddingModel = embeddingModel;\n    }\n\n    @GetMapping(\"/ai/embedding\")\n    public Map embed(@RequestParam(value = \"message\", defaultValue = \"Tell me a joke\") String message) {\n        EmbeddingResponse embeddingResponse = this.embeddingModel.embedForResponse(List.of(message));\n        return Map.of(\"embedding\", embeddingResponse);\n    }\n}\n----\n\n== Manual Configuration\n\nIf you are not using Spring Boot, you can manually configure the `OllamaEmbeddingModel`.\nFor this add the spring-ai-ollama dependency to your project’s Maven pom.xml or Gradle `build.gradle` build files:\n\n[tabs]\n======\nMaven::\n+\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-ollama</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-ollama'\n}\n----\n======\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nNOTE: The `spring-ai-ollama` dependency provides access also to the `OllamaChatModel`.\nFor more information about the `OllamaChatModel` refer to the link:../chat/ollama-chat.html[Ollama Chat Client] section.\n\nNext, create an `OllamaEmbeddingModel` instance and use it to compute the embeddings for two input texts using a dedicated `chroma/all-minilm-l6-v2-f32` embedding models:\n\n[source,java]\n----\nvar ollamaApi = OllamaApi.builder().build();\n\nvar embeddingModel = new OllamaEmbeddingModel(this.ollamaApi,\n        OllamaEmbeddingOptions.builder()\n\t\t\t.model(OllamaModel.MISTRAL.id())\n            .build());\n\nEmbeddingResponse embeddingResponse = this.embeddingModel.call(\n    new EmbeddingRequest(List.of(\"Hello World\", \"World is big and salvation is near\"),\n        OllamaEmbeddingOptions.builder()\n            .model(\"chroma/all-minilm-l6-v2-f32\"))\n            .truncate(false)\n            .build());\n----\n\nThe `OllamaEmbeddingOptions` provides the configuration information for all embedding requests.\n"

    "content": "[[EmbeddingModel]]\n= Embeddings Model API\n\nEmbeddings are numerical representations of text, images, or videos that capture relationships between inputs. \n\nEmbeddings work by converting text, image, and video into arrays of floating point numbers, called vectors. \nThese vectors are designed to capture the meaning of the text, images, and videos. \nThe length of the embedding array is called the vector's dimensionality. \n\nBy calculating the numerical distance between the vector representations of two pieces of text, an application can determine the similarity between the objects used to generate the embedding vectors.\n\nThe `EmbeddingModel` interface is designed for straightforward integration with embedding models in AI and machine learning.\nIts primary function is to convert text into numerical vectors, commonly referred to as embeddings.\nThese embeddings are crucial for various tasks such as semantic analysis and text classification.\n\nThe design of the EmbeddingModel interface centers around two primary goals:\n\n* *Portability*: This interface ensures easy adaptability across various embedding models.\nIt allows developers to switch between different embedding techniques or models with minimal code changes.\nThis design aligns with Spring's philosophy of modularity and interchangeability.\n\n* *Simplicity*: EmbeddingModel simplifies the process of converting text to embeddings.\nBy providing straightforward methods like `embed(String text)` and `embed(Document document)`, it takes the complexity out of dealing with raw text data and embedding algorithms. This design choice makes it easier for developers, especially those new to AI, to utilize embeddings in their applications without delving deep into the underlying mechanics.\n\n== API Overview\n\nThe Embedding Model API is built on top of the generic https://github.com/spring-projects/spring-ai/tree/main/spring-ai-model/src/main/java/org/springframework/ai/model[Spring AI Model API], which is a part of the Spring AI library.\nAs such, the EmbeddingModel interface extends the `Model` interface, which provides a standard set of methods for interacting with AI models. The `EmbeddingRequest` and `EmbeddingResponse` classes extend from the `ModelRequest` and `ModelResponse` are used to encapsulate the input and output of the embedding models, respectively.\n\nThe Embedding API in turn is used by higher-level components to implement Embedding Models for specific embedding models, such as OpenAI, Titan, Azure OpenAI, Ollie, and others.\n\nFollowing diagram illustrates the Embedding API and its relationship with the Spring AI Model API and the Embedding Models:\n\nimage:embeddings-api.jpg[title=Embeddings API,align=center,width=900]\n\n=== EmbeddingModel\n\nThis section provides a guide to the `EmbeddingModel` interface and associated classes.\n\n[source,java]\n----\npublic interface EmbeddingModel extends Model<EmbeddingRequest, EmbeddingResponse> {\n\n\t@Override\n\tEmbeddingResponse call(EmbeddingRequest request);\n\n\n\t/**\n\t * Embeds the given document's content into a vector.\n\t * @param document the document to embed.\n\t * @return the embedded vector.\n\t */\n\tfloat[] embed(Document document);\n\n\t/**\n\t * Extracts the text content from a Document to be used for embedding.\n\t * By default, returns Document.getText().

`VectorStore` an implementation of `DocumentWriter`\n\nTo perform the basic loading of data into a Vector Database for use with the Retrieval Augmented Generation pattern, use the following code in Java function style syntax.\n\n[source,java]\n----\nvectorStore.accept(tokenTextSplitter.apply(pdfReader.get()));\n----\n\nAlternatively, you can use method names that are more naturally expressive

{\n\n\tprivate final Resource resource;\n\n    MyJsonReader(@Value(\"classpath:bikes.json\") Resource resource) {\n        this.resource = resource;\n    }\n\n\tList<Document> loadJsonAsDocuments() {\n        JsonReader jsonReader = new JsonReader(this.resource, \"description\", \"content\");\n        return jsonReader.get();\n\t}\n}\n----\n\n==== Constructor Options\n\nThe `JsonReader` provides several constructor options:\n\n1. `JsonReader(Resource resource)`\n2. `JsonReader(Resource resource, String... jsonKeysToUse)`\n3. `JsonReader(Resource resource, JsonMetadataGenerator jsonMetadataGenerator, String... jsonKeysToUse)`\n\n==== Parameters\n\n* `resource`: A Spring `Resource` object pointing to the JSON file.\n* `jsonKeysToUse`: An array of keys from the JSON that should be used as the text content in the resulting `Document` objects.\n* `jsonMetadataGenerator`: An optional `JsonMetadataGenerator` to create metadata for each `Document`.\n\n==== Behavior\n\nThe `JsonReader` processes JSON content as follows:\n\n* It can handle both JSON arrays and single JSON objects.\n* For each JSON object (either in an array or a single object):\n** It extracts the content based on the specified `jsonKeysToUse`.\n** If no keys are specified, it uses the entire JSON object as content.\n** It generates metadata using the provided `JsonMetadataGenerator` (or an empty one if not provided).\n** It creates a `Document` object with the extracted content and metadata.\n\n\n==== Using JSON Pointers\n\nThe `JsonReader` now supports retrieving specific parts of a JSON document using JSON Pointers. This feature allows you to easily extract nested data from complex JSON structures.\n\n===== The `get(String pointer)` method\n\n[source,java]\n----\npublic List<Document> get(String pointer)\n----\n\nThis method allows you to use a JSON Pointer to retrieve a specific part of the JSON document.\n\n====== Parameters\n\n* `pointer`: A JSON Pointer string (as defined in RFC 6901) to locate the desired element within the JSON structure.\n\n====== Return Value\n\n* Returns a `List<Document>` containing the documents parsed from the JSON element located by the pointer.\n\n====== Behavior\n\n* The method uses the provided JSON Pointer to navigate to a specific location in the JSON structure.\n* If the pointer is valid and points to an existing element:\n** For a JSON object: it returns a list with a single Document.\n** For a JSON array: it returns a list of Documents, one for each element in the array.\n* If the pointer is invalid or points to a non-existent element, it throws an `IllegalArgumentException`.\n\n====== Example\n\n[source,java]\n----\nJsonReader jsonReader = new JsonReader(resource, \"description\");\nList<Document> documents = this.jsonReader.get(\"/store/books/0\");\n----\n\n==== Example JSON Structure\n\n[source,json]\n----\n[\n  {\n    \"id\": 1,\n    \"brand\": \"Trek\",\n    \"description\": \"A high-performance mountain bike for trail riding.\"\n  },\n  {\n    \"id\": 2,\n    \"brand\": \"Cannondale\",\n    \"description\": \"An aerodynamic road bike for racing enthusiasts.\"\n  }\n]\n----\n\nIn this example, if the `JsonReader` is configured with `\"description\"` as the `jsonKeysToUse`, it will create `Document` objects where the content is the value of the \"description\" field for each bike in the array.\n\n==== Notes\n\n* The `JsonReader` uses Jackson for JSON parsing.\n* It can handle large JSON files efficiently by using streaming for arrays.\n* If multiple keys are specified in `jsonKeysToUse`, the content will be a concatenation of the values for those keys.\n* The reader is flexible and can be adapted to various JSON structures by customizing the `jsonKeysToUse` and `JsonMetadataGenerator`.\n\n\n=== Text\nThe `TextReader` processes plain text documents, converting them into a list of `Document` objects.\n\n==== Example\n\n[source,java]\n----\n@Component\nclass MyTextReader {\n\n    private final Resource resource;\n\n    MyTextReader(@Value(\"classpath:text-source.txt\") Resource resource) {\n        this.resource = resource;\n    }\n\n\tList<Document> loadText() {\n\t\tTextReader textReader = new TextReader(this.resource);\n\t\ttextReader.getCustomMetadata().put(\"filename\", \"text-source.txt\");\n\n\t\treturn textReader.read();\n    }\n}\n----\n\n==== Constructor Options\n\nThe `TextReader` provides two constructor options:\n\n1. `TextReader(String resourceUrl)`\n2. `TextReader(Resource resource)`\n\n==== Parameters\n\n* `resourceUrl`: A string representing the URL of the resource to be read.\n* `resource`: A Spring `Resource` object pointing to the text file.\n\n==== Configuration\n\n* `setCharset(Charset charset)`: Sets the character set used for reading the text file. Default is UTF-8.\n* `getCustomMetadata()`: Returns a mutable map where you can add custom metadata for the documents.\n\n==== Behavior\n\nThe `TextReader` processes text content as follows:\n\n* It reads the entire content of the text file into a single `Document` object.\n* The content of the file becomes the content of the `Document`.\n* Metadata is automatically added to the `Document`:\n** `charset`: The character set used to read the file (default: \"UTF-8\").\n** `source`: The filename of the source text file.\n* Any custom metadata added via `getCustomMetadata()` is included in the `Document`.\n\n\n==== Notes\n\n* The `TextReader` reads the entire file content into memory, so it may not be suitable for very large files.\n* If you need to split the text into smaller chunks, you can use a text splitter like `TokenTextSplitter` after reading the document:\n\n[source,java]\n----\nList<Document> documents = textReader.get();\nList<Document> splitDocuments = TokenTextSplitter.builder().build().apply(this.documents);\n----\n\n* The reader uses Spring's `Resource` abstraction, allowing it to read from various sources (classpath, file system, URL, etc.).\n* Custom metadata can be added to all documents created by the reader using the `getCustomMetadata()` method.\n\n\n=== HTML (JSoup)\n\nThe `JsoupDocumentReader` processes HTML documents, converting them into a list of `Document` objects using the JSoup library.\n\n==== Dependencies\nAdd the dependency to your project using Maven or Gradle.\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-jsoup-document-reader</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-jsoup-document-reader'\n}\n----\n======\n\n==== Example\n\n[source,java]\n----\n@Component\nclass MyHtmlReader {\n\n    private final Resource resource;\n\n    MyHtmlReader(@Value(\"classpath:/my-page.html\") Resource resource) {\n        this.resource = resource;\n    }\n\n    List<Document> loadHtml() {\n        JsoupDocumentReaderConfig config = JsoupDocumentReaderConfig.builder()\n            .selector(\"article p\") // Extract paragraphs within <article> tags\n            .charset(\"ISO-8859-1\")  // Use ISO-8859-1 encoding\n            .includeLinkUrls(true) // Include link URLs in metadata\n            .metadataTags(List.of(\"author\", \"date\")) // Extract author and date meta tags\n            .additionalMetadata(\"source\", \"my-page.html\") // Add custom metadata\n            .build();\n\n        JsoupDocumentReader reader = new JsoupDocumentReader(this.resource, config);\n        return reader.get();\n    }\n}\n----\n\nThe `JsoupDocumentReaderConfig` allows you to customize the behavior of the `JsoupDocumentReader`:\n\n*   `charset`:  Specifies the character encoding of the HTML document (defaults to \"UTF-8\").\n*   `selector`:  A JSoup CSS selector to specify which elements to extract text from (defaults to \"body\").\n*   `separator`:  The string used to join text from multiple selected elements (defaults to \"\\n\").\n*   `allElements`:  If `true`, extracts all text from the `<body>` element, ignoring the `selector` (defaults to `false`).\n*   `groupByElement`: If `true`, creates a separate `Document` for each element matched by the `selector` (defaults to `false`).\n*   `includeLinkUrls`:  If `true`, extracts absolute link URLs and adds them to the metadata (defaults to `false`).\n*   `metadataTags`:  A list of `<meta>` tag names to extract content from (defaults to `[\"description\", \"keywords\"]`).\n*   `additionalMetadata`:  Allows you to add custom metadata to all created `Document` objects.\n\n==== Sample Document: my-page.html\n\n[source,html]\n----\n<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n    <meta charset=\"UTF-8\">\n    <title>My Web Page</title>\n    <meta name=\"description\" content=\"A sample web page for Spring AI\">\n    <meta name=\"keywords\" content=\"spring, ai, html, example\">\n    <meta name=\"author\" content=\"John Doe\">\n    <meta name=\"date\" content=\"2024-01-15\">\n    <link rel=\"stylesheet\" href=\"style.css\">\n</head>\n<body>\n    <header>\n        <h1>Welcome to My Page</h1>\n    </header>\n    <nav>\n        <ul>\n            <li><a href=\"/\">Home</a></li>\n            <li><a href=\"/about\">About</a></li>\n        </ul>\n    </nav>\n    <article>\n        <h2>Main Content</h2>\n        <p>This is the main content of my web page.</p>\n        <p>It contains multiple paragraphs.</p>\n        <a href=\"https://www.example.com\">External Link</a>\n    </article>\n    <footer>\n        <p>&copy; 2024 John Doe</p>\n    </footer>\n</body>\n</html>\n----\n\nBehavior:\n\nThe `JsoupDocumentReader` processes the HTML content and creates `Document` objects based on the configuration:\n\n*   The `selector` determines which elements are used for text extraction.\n*   If `allElements` is `true`, all text within the `<body>` is extracted into a single `Document`.\n*   If `groupByElement` is `true`, each element matching the `selector` creates a separate `Document`.\n*   If neither `allElements` nor `groupByElement` is `true`, text from all elements matching the `selector` is joined using the `separator`.\n*   The document title, content from specified `<meta>` tags, and (optionally) link URLs are added to the `Document` metadata.\n*   The base URI, for resolving relative links, will be extracted from URL resources.\n\nThe reader preserves the text content of the selected elements, but removes any HTML tags within them.\n\n\n=== Markdown\n\nThe `MarkdownDocumentReader` processes Markdown documents, converting them into a list of `Document` objects.\n\n==== Dependencies\nAdd the dependency to your project using Maven or Gradle.\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-markdown-document-reader</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-markdown-document-reader'\n}\n----\n======\n\n==== Example\n\n[source,java]\n----\n@Component\nclass MyMarkdownReader {\n\n    private final Resource resource;\n\n    MyMarkdownReader(@Value(\"classpath:code.md\") Resource resource) {\n        this.resource = resource;\n    }\n\n    List<Document> loadMarkdown() {\n        MarkdownDocumentReaderConfig config = MarkdownDocumentReaderConfig.builder()\n            .withHorizontalRuleCreateDocument(true)\n            .withIncludeCodeBlock(false)\n            .withIncludeBlockquote(false)\n            .withAdditionalMetadata(\"filename\", \"code.md\")\n            .build();\n\n        MarkdownDocumentReader reader = new MarkdownDocumentReader(this.resource, config);\n        return reader.get();\n    }\n}\n----\n\nThe `MarkdownDocumentReaderConfig` allows you to customize the behavior of the MarkdownDocumentReader:\n\n* `horizontalRuleCreateDocument`: When set to `true`, horizontal rules in the Markdown will create new `Document` objects.\n* `includeCodeBlock`: When set to `true`, code blocks will be included in the same `Document` as the surrounding text. When `false`, code blocks create separate `Document` objects.\n* `includeBlockquote`: When set to `true`, blockquotes will be included in the same `Document` as the surrounding text. When `false`, blockquotes create separate `Document` objects.\n* `additionalMetadata`: Allows you to add custom metadata to all created `Document` objects.\n\n==== Sample Document: code.md\n\n[source,markdown]\n----\nThis is a Java sample application:\n\n```java\npackage com.example.demo;\n\nimport org.springframework.boot.SpringApplication;\nimport org.springframework.boot.autoconfigure.SpringBootApplication;\n\n@SpringBootApplication\npublic class DemoApplication {\n    public static void main(String[] args) {\n        SpringApplication.run(DemoApplication.class, args);\n    }\n}\n```\n\nMarkdown also provides the possibility to `use inline code formatting throughout` the entire sentence.\n\n---\n\nAnother possibility is to set block code without specific highlighting:\n\n```\n./mvnw spring-javaformat:apply\n```\n----\n\nBehavior: The MarkdownDocumentReader processes the Markdown content and creates Document objects based on the configuration:\n\n* Headers become metadata in the Document objects.\n* Paragraphs become the content of Document objects.\n* Code blocks can be separated into their own Document objects or included with surrounding text.\n* Blockquotes can be separated into their own Document objects or included with surrounding text.\n* Horizontal rules can be used to split the content into separate Document objects.\n\nThe reader preserves formatting like inline code, lists, and text styling within the content of the Document objects.\n\n\n=== PDF Page\nThe `PagePdfDocumentReader` uses Apache PdfBox library to parse PDF documents.\n\n==== Dependencies\nAdd the dependency to your project using Maven or Gradle.\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-pdf-document-reader</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-pdf-document-reader'\n}\n----\n======\n\n==== Example\n\n[source,java]\n----\n@Component\npublic class MyPagePdfDocumentReader {\n\n\tList<Document> getDocsFromPdf() {\n\n\t\tPagePdfDocumentReader pdfReader = new PagePdfDocumentReader(\"classpath:/sample1.pdf\",\n\t\t\t\tPdfDocumentReaderConfig.builder()\n\t\t\t\t\t.withPageTopMargin(0)\n\t\t\t\t\t.withPageExtractedTextFormatter(ExtractedTextFormatter.builder()\n\t\t\t\t\t\t.withNumberOfTopTextLinesToDelete(0)\n\t\t\t\t\t\t.build())\n\t\t\t\t\t.withPagesPerDocument(1)\n\t\t\t\t\t.build());\n\n\t\treturn pdfReader.read();\n    }\n\n}\n\n----\n\n=== PDF Paragraph\nThe `ParagraphPdfDocumentReader` uses the PDF catalog (e.g. TOC) information to split the input PDF into text paragraphs and output a single `Document` per paragraph.\nNOTE: Not all PDF documents contain the PDF catalog.\n\n==== Dependencies\nAdd the dependency to your project using Maven or Gradle.\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-pdf-document-reader</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-pdf-document-reader'\n}\n----\n======\n\n==== Example\n\n[source,java]\n----\n@Component\npublic class MyPagePdfDocumentReader {\n\n\tList<Document> getDocsFromPdfWithCatalog() {\n\n        ParagraphPdfDocumentReader pdfReader = new ParagraphPdfDocumentReader(\"classpath:/sample1.pdf\",\n                PdfDocumentReaderConfig.builder()\n                    .withPageTopMargin(0)\n                    .withPageExtractedTextFormatter(ExtractedTextFormatter.builder()\n                        .withNumberOfTopTextLinesToDelete(0)\n                        .build())\n                    .withPagesPerDocument(1)\n                    .build());\n\n\t    return pdfReader.read();\n    }\n}\n----\n\n\n=== Tika (DOCX, PPTX, HTML...)\nThe `TikaDocumentReader` uses Apache Tika to extract text from a variety of document formats, such as PDF, DOC/DOCX, PPT/PPTX, and HTML. For a comprehensive list of supported formats, refer to the  https://tika.apache.org/3.1.0/formats.html[Tika documentation].\n\n==== Dependencies\nAdd the dependency to your project using Maven or Gradle.\n\n[tabs]\n======\nMaven::\n+\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-tika-document-reader</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-tika-document-reader'\n}\n----\n======\n\n==== Example\n\n[source,java]\n----\n@Component\nclass MyTikaDocumentReader {\n\n    private final Resource resource;\n\n    MyTikaDocumentReader(@Value(\"classpath:/word-sample.docx\")\n                            Resource resource) {\n        this.resource = resource;\n    }\n\n    List<Document> loadText() {\n        TikaDocumentReader tikaDocumentReader = new TikaDocumentReader(this.resource);\n        return tikaDocumentReader.read();\n    }\n}\n----\n\n== Transformers\n\n=== TextSplitter\nThe `TextSplitter` an abstract base class that helps divides documents to fit the AI model's context window.\n\n\n=== TokenTextSplitter\nThe `TokenTextSplitter` is an implementation of `TextSplitter` that splits text into chunks based on token count. It supports configurable encoding types (e.g., `CL100K_BASE`, `P50K_BASE`, `O200K_BASE`) and defaults to `CL100K_BASE`.\n\n==== Usage\n\n===== Basic Usage\n\n[source,java]\n----\n@Component\nclass MyTokenTextSplitter {\n\n    public List<Document> splitDocuments(List<Document> documents) {\n        TokenTextSplitter splitter = TokenTextSplitter.builder().build();\n        return splitter.apply(documents);\n    }\n\n    public List<Document> splitCustomized(List<Document> documents) {\n        TokenTextSplitter splitter = TokenTextSplitter.builder()\n            .withChunkSize(1000)\n            .withMinChunkSizeChars(400)\n            .withMinChunkLengthToEmbed(10)\n            .withMaxNumChunks(5000)\n            .withKeepSeparator(true)\n            .build();\n        return splitter.apply(documents);\n    }\n}\n----\n\n===== Custom Encoding Type\n\nYou can configure the encoding type used for tokenization. This is useful when working with models that use different tokenizers:\n\n[source,java]\n----\nTokenTextSplitter splitter = TokenTextSplitter.builder()\n    .withEncodingType(EncodingType.O200K_BASE)\n    .withChunkSize(1000)\n    .build();\n----\n\n===== Custom Punctuation Marks\n\nYou can customize the punctuation marks used for splitting text into semantically meaningful chunks. This is particularly useful for internationalization:\n\n[source,java]\n----\n@Component\nclass MyInternationalTextSplitter {\n\n    public List<Document> splitChineseText(List<Document> documents) {\n        // Use Chinese punctuation marks\n        TokenTextSplitter splitter = TokenTextSplitter.builder()\n            .withChunkSize(800)\n            .withMinChunkSizeChars(350)\n            .withPunctuationMarks(List.of('。', '？', '！', '；'))  // Chinese punctuation\n            .build();\n\n        return splitter.apply(documents);\n    }\n\n    public List<Document> splitWithCustomMarks(List<Document> documents) {\n        // Mix of English and other punctuation marks\n        TokenTextSplitter splitter = TokenTextSplitter.builder()\n            .withChunkSize(800)\n            .withPunctuationMarks(List.of('.', '?', '!', '\\n', ';', ':', '。'))\n            .build();\n\n        return splitter.apply(documents);\n    }\n}\n----\n\n==== Configuration\n\nUse `TokenTextSplitter.builder()` to create instances. All constructors are deprecated in favor of the builder.\n\n==== Parameters\n\n* `encodingType`: The tokenizer encoding type to use (default: `CL100K_BASE`). Supported values include `CL100K_BASE`, `P50K_BASE`, and `O200K_BASE`.\n* `chunkSize`: The target size of each text chunk in tokens (default: 800).\n* `minChunkSizeChars`: The minimum size of each text chunk in characters (default: 350).\n* `minChunkLengthToEmbed`: The minimum length of a chunk to be included (default: 5).\n* `maxNumChunks`: The maximum number of chunks to generate from a text (default: 10000).\n* `keepSeparator`: Whether to keep separators (like newlines) in the chunks (default: true).\n* `punctuationMarks`: List of characters to use as sentence boundaries for splitting (default: `.`, `?`, `!`, `\\n`).\n\n==== Behavior\n\nThe `TokenTextSplitter` processes text content as follows:\n\n1. It encodes the input text into tokens using the CL100K_BASE encoding.\n2. It splits the encoded text into chunks based on the `chunkSize`.\n3. For each chunk:\n   a. It decodes the chunk back into text.\n   b. *Only if the total token count exceeds the chunk size*, it attempts to find a suitable break point (using the configured `punctuationMarks`) after the `minChunkSizeChars`.\n   c. If a break point is found, it truncates the chunk at that point.\n   d. It trims the chunk and optionally removes newline characters based on the `keepSeparator` setting.\n   e. If the resulting chunk is longer than `minChunkLengthToEmbed`, it's added to the output.\n4. This process continues until all tokens are processed or `maxNumChunks` is reached.\n5. Any remaining text is added as a final chunk if it's longer than `minChunkLengthToEmbed`.\n\nIMPORTANT: Punctuation-based splitting only applies when the token count exceeds the chunk size. Text that exactly matches or is smaller than the chunk size is returned as a single chunk without punctuation-based truncation. This prevents unnecessary splitting of small texts.\n\n==== Example\n\n[source,java]\n----\nDocument doc1 = new Document(\"This is a long piece of text that needs to be split into smaller chunks for processing.\",\n        Map.of(\"source\", \"example.txt\"));\nDocument doc2 = new Document(\"Another document with content that will be split based on token count.\",\n        Map.of(\"source\", \"example2.txt\"));\n\nTokenTextSplitter splitter = TokenTextSplitter.builder().build();\nList<Document> splitDocuments = splitter.apply(List.of(doc1, doc2));\n\nfor (Document doc : splitDocuments) {\n    System.out.println(\"Chunk: \" + doc.getContent());\n    System.out.println(\"Metadata: \" + doc.getMetadata());\n}\n----\n\n\n==== Notes\n\n* The `TokenTextSplitter` uses the CL100K_BASE encoding from the `jtokkit` library, which is compatible with newer OpenAI models.\n* The splitter attempts to create semantically meaningful chunks by breaking at sentence boundaries where possible.\n* Metadata from the original documents is preserved and copied to all chunks derived from that document.\n* The content formatter (if set) from the original document is also copied to the derived chunks if `copyContentFormatter` is set to `true` (default behavior).\n* This splitter is particularly useful for preparing text for large language models that have token limits, ensuring that each chunk is within the model's processing capacity.\n* *Custom Punctuation Marks*: The default punctuation marks (`.`, `?`, `!`, `\\n`) work well for English text. For other languages or specialized content, customize the punctuation marks using the builder's `withPunctuationMarks()` method.\n* *Performance Consideration*: While the splitter can handle any number of punctuation marks, it's recommended to keep the list reasonably small (under 20 characters) for optimal performance, as each mark is checked for every chunk.\n* *Extensibility*: The `getLastPunctuationIndex(String)` method is `protected`, allowing subclasses to override the punctuation detection logic for specialized use cases.\n* *Small Text Handling*: As of version 2.0, small texts (with token count at or below the chunk size) are no longer split at punctuation marks, preventing unnecessary fragmentation of content that already fits within the size limits.\n\n=== ContentFormatTransformer\nEnsures uniform content formats across all documents.\n\n=== KeywordMetadataEnricher\nThe `KeywordMetadataEnricher` is a `DocumentTransformer` that uses a generative AI model to extract keywords from document content and add them as metadata.\n\n==== Usage\n\n[source,java]\n----\n@Component\nclass MyKeywordEnricher {\n\n    private final ChatModel chatModel;\n\n    MyKeywordEnricher(ChatModel chatModel) {\n        this.chatModel = chatModel;\n    }\n\n    List<Document> enrichDocuments(List<Document> documents) {\n        KeywordMetadataEnricher enricher = KeywordMetadataEnricher.builder(chatModel)\n                .keywordCount(5)\n                .build();\n\n        // Or use custom templates\n        KeywordMetadataEnricher enricher = KeywordMetadataEnricher.builder(chatModel)\n               .keywordsTemplate(YOUR_CUSTOM_TEMPLATE)\n               .build();\n\n        return enricher.apply(documents);\n    }\n}\n----\n\n==== Constructor Options\n\nThe `KeywordMetadataEnricher` provides two constructor options:\n\n1. `KeywordMetadataEnricher(ChatModel chatModel, int keywordCount)`: To use the default template and extract a specified number of keywords.\n2. `KeywordMetadataEnricher(ChatModel chatModel, PromptTemplate keywordsTemplate)`: To use a custom template for keyword extraction.\n\n==== Behavior\n\nThe `KeywordMetadataEnricher` processes documents as follows:\n\n1. For each input document, it creates a prompt using the document's content.\n2. It sends this prompt to the provided `ChatModel` to generate keywords.\n3. The generated keywords are added to the document's metadata under the key \"excerpt_keywords\".\n4. The enriched documents are returned.\n\n\n==== Customization\n\nYou can use the default template or customize the template through the keywordsTemplate parameter.\nThe default template is:\n\n[source,java]\n----\n\\{context_str}. Give %s unique keywords for this document. Format as comma separated. Keywords:\n----\n\nWhere `+{context_str}+` is replaced with the document content, and `%s` is replaced with the specified keyword count.\n\n==== Example\n\n[source,java]\n----\nChatModel chatModel = // initialize your chat model\nKeywordMetadataEnricher enricher = KeywordMetadataEnricher.builder(chatModel)\n                .keywordCount(5)\n                .build();\n\n// Or use custom templates\nKeywordMetadataEnricher enricher = KeywordMetadataEnricher.builder(chatModel)\n                .keywordsTemplate(new PromptTemplate(\"Extract 5 important keywords from the following text and separate them with commas:\\n{context_str}\"))\n                .build();\n\nDocument doc = new Document(\"This is a document about artificial intelligence and its applications in modern technology.\");\n\nList<Document> enrichedDocs = enricher.apply(List.of(this.doc));\n\nDocument enrichedDoc = this.enrichedDocs.get(0);\nString keywords = (String) this.enrichedDoc.getMetadata().get(\"excerpt_keywords\");\nSystem.out.println(\"Extracted keywords: \" + keywords);\n----\n\n==== Notes\n\n* The `KeywordMetadataEnricher` requires a functioning `ChatModel` to generate keywords.\n* The keyword count must be 1 or greater.\n* The enricher adds the \"excerpt_keywords\" metadata field to each processed document.\n* The generated keywords are returned as a comma-separated string.\n* This enricher is particularly useful for improving document searchability and for generating tags or categories for documents.\n* In the Builder pattern, if the `keywordsTemplate` parameter is set, the `keywordCount` parameter will be ignored.\n\n=== SummaryMetadataEnricher\nThe `SummaryMetadataEnricher` is a `DocumentTransformer` that uses a generative AI model to create summaries for documents and add them as metadata. It can generate summaries for the current document, as well as adjacent documents (previous and next).\n\n==== Usage\n\n[source,java]\n----\n@Configuration\nclass EnricherConfig {\n\n    @Bean\n    public SummaryMetadataEnricher summaryMetadata(OpenAiChatModel aiClient) {\n        return new SummaryMetadataEnricher(aiClient,\n            List.of(SummaryType.PREVIOUS, SummaryType.CURRENT, SummaryType.NEXT));\n    }\n}\n\n@Component\nclass MySummaryEnricher {\n\n    private final SummaryMetadataEnricher enricher;\n\n    MySummaryEnricher(SummaryMetadataEnricher enricher) {\n        this.enricher = enricher;\n    }\n\n    List<Document> enrichDocuments(List<Document> documents) {\n        return this.enricher.apply(documents);\n    }\n}\n----\n\n\n==== Constructor\n\nThe `SummaryMetadataEnricher` provides two constructors:\n\n1. `SummaryMetadataEnricher(ChatModel chatModel, List<SummaryType> summaryTypes)`\n2. `SummaryMetadataEnricher(ChatModel chatModel, List<SummaryType> summaryTypes, String summaryTemplate, MetadataMode metadataMode)`\n\n==== Parameters\n\n* `chatModel`: The AI model used for generating summaries.\n* `summaryTypes`: A list of `SummaryType` enum values indicating which summaries to generate (PREVIOUS, CURRENT, NEXT).\n* `summaryTemplate`: A custom template for summary generation (optional).\n* `metadataMode`: Specifies how to handle document metadata when generating summaries (optional).\n\n\n==== Behavior\n\nThe `SummaryMetadataEnricher` processes documents as follows:\n\n1. For each input document, it creates a prompt using the document's content and the specified summary template.\n2. It sends this prompt to the provided `ChatModel` to generate a summary.\n3. Depending on the specified `summaryTypes`, it adds the following metadata to each document:\n* `section_summary`: Summary of the current document.\n* `prev_section_summary`: Summary of the previous document (if available and requested).\n* `next_section_summary`: Summary of the next document (if available and requested).\n4. The enriched documents are returned.\n\n==== Customization\n\nThe summary generation prompt can be customized by providing a custom `summaryTemplate`. The default template is:\n\n[source,java]\n----\n\"\"\"\nHere is the content of the section:\n{context_str}\n\nSummarize the key topics and entities of the section.\n\nSummary:\n\"\"\"\n----\n\n==== Example\n\n[source,java]\n----\nChatModel chatModel = // initialize your chat model\nSummaryMetadataEnricher enricher = new SummaryMetadataEnricher(chatModel,\n    List.of(SummaryType.PREVIOUS, SummaryType.CURRENT, SummaryType.NEXT));\n\nDocument doc1 = new Document(\"Content of document 1\");\nDocument doc2 = new Document(\"Content of document 2\");\n\nList<Document> enrichedDocs = enricher.apply(List.of(this.doc1, this.doc2));\n\n// Check the metadata of the enriched documents\nfor (Document doc : enrichedDocs) {\n    System.out.println(\"Current summary: \" + doc.getMetadata().get(\"section_summary\"));\n    System.out.println(\"Previous summary: \" + doc.getMetadata().get(\"prev_section_summary\"));\n    System.out.println(\"Next summary: \" + doc.getMetadata().get(\"next_section_summary\"));\n}\n----\n\nThe provided example demonstrates the expected behavior:\n\n* For a list of two documents, both documents receive a `section_summary`.\n* The first document receives a `next_section_summary` but no `prev_section_summary`.\n* The second document receives a `prev_section_summary` but no `next_section_summary`.\n* The `section_summary` of the first document matches the `prev_section_summary` of the second document.\n* The `next_section_summary` of the first document matches the `section_summary` of the second document.\n\n==== Notes\n\n* The `SummaryMetadataEnricher` requires a functioning `ChatModel` to generate summaries.\n* The enricher can handle document lists of any size, properly handling edge cases for the first and last documents.\n* This enricher is particularly useful for creating context-aware summaries, allowing for better understanding of document relationships in a sequence.\n* The `MetadataMode` parameter allows control over how existing metadata is incorporated into the summary generation process.\n\n\n== Writers\n\n=== File\n\nThe `FileDocumentWriter` is a `DocumentWriter` implementation that writes the content of a list of `Document` objects into a file.\n\n==== Usage\n\n[source,java]\n----\n@Component\nclass MyDocumentWriter {\n\n    public void writeDocuments(List<Document> documents) {\n        FileDocumentWriter writer = new FileDocumentWriter(\"output.txt\", true, MetadataMode.ALL, false);\n        writer.accept(documents);\n    }\n}\n----\n\n==== Constructors\n\nThe `FileDocumentWriter` provides three constructors:\n\n1. `FileDocumentWriter(String fileName)`\n2. `FileDocumentWriter(String fileName, boolean withDocumentMarkers)`\n3. `FileDocumentWriter(String fileName, boolean withDocumentMarkers, MetadataMode metadataMode, boolean append)`\n\n==== Parameters\n\n* `fileName`: The name of the file to write the documents to.\n* `withDocumentMarkers`: Whether to include document markers in the output (default: false).\n* `metadataMode`: Specifies what document content to be written to the file (default: MetadataMode.NONE).\n* `append`: If true, data will be written to the end of the file rather than the beginning (default: false).\n\n==== Behavior\n\nThe `FileDocumentWriter` processes documents as follows:\n\n1. It opens a FileWriter for the specified file name.\n2. For each document in the input list:\na. If `withDocumentMarkers` is true, it writes a document marker including the document index and page numbers.\nb. It writes the formatted content of the document based on the specified `metadataMode`.\n3. The file is closed after all documents have been written.\n\n\n\n==== Document Markers\n\nWhen `withDocumentMarkers` is set to true, the writer includes markers for each document in the following format:\n\n[source]\n----\n### Doc: [index], pages:[start_page_number,end_page_number]\n----\n\n==== Metadata Handling\n\nThe writer uses two specific metadata keys:\n\n* `page_number`: Represents the starting page number of the document.\n* `end_page_number`: Represents the ending page number of the document.\n\nThese are used when writing document markers.\n\n==== Example\n\n[source,java]\n----\nList<Document> documents = // initialize your documents\nFileDocumentWriter writer = new FileDocumentWriter(\"output.txt\", true, MetadataMode.ALL, true);\nwriter.accept(documents);\n----\n\nThis will write all documents to \"output.txt\", including document markers, using all available metadata, and appending to the file if it already exists.\n\n==== Notes\n\n* The writer uses `FileWriter`, so it writes text files with the default character encoding of the operating system.\n* If an error occurs during writing, a `RuntimeException` is thrown with the original exception as its cause.\n* The `metadataMode` parameter allows control over how existing metadata is incorporated into the written content.\n* This writer is particularly useful for debugging or creating human-readable outputs of document collections.\n\n\n=== VectorStore\n\nProvides integration with various vector stores.\nSee xref:api/vectordbs.adoc[Vector DB Documentation] for a full listing.\n"

    "content": "= Azure OpenAI Image Generation\n\n\nSpring AI supports the gpt-image-1-mini image generation model from Azure OpenAI.\n\n== Prerequisites\n\nObtain your Azure OpenAI `endpoint` and `api-key` from the Azure OpenAI Service section on the link:https://portal.azure.com[Azure Portal].\n\nSpring AI defines two configuration properties:\n\n1. `spring.ai.azure.openai.api-key`: Set this to the value of the `API Key` obtained from Azure.\n2. `spring.ai.azure.openai.endpoint`: Set this to the endpoint URL obtained when provisioning your model in Azure.\n\nYou can set these configuration properties in your `application.properties` file:\n\n[source,properties]\n----\nspring.ai.azure.openai.api-key=<your-azure-openai-api-key>\nspring.ai.azure.openai.endpoint=<your-azure-openai-endpoint>\n----\n\nFor enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference custom environment variables:\n\n[source,yaml]\n----\n# In application.yml\nspring:\n  ai:\n    azure:\n      openai:\n        api-key: ${AZURE_OPENAI_API_KEY}\n        endpoint: ${AZURE_OPENAI_ENDPOINT}\n----\n\n[source,bash]\n----\n# In your environment or .env file\nexport AZURE_OPENAI_API_KEY=<your-azure-openai-api-key>\nexport AZURE_OPENAI_ENDPOINT=<your-azure-openai-endpoint>\n----\n\nYou can also set these configurations programmatically in your application code:\n\n[source,java]\n----\n// Retrieve API key and endpoint from secure sources or environment variables\nString apiKey = System.getenv(\"AZURE_OPENAI_API_KEY\");\nString endpoint = System.getenv(\"AZURE_OPENAI_ENDPOINT\");\n----\n\n=== Deployment Name\n\nTo use run Azure AI applications, create an Azure AI Deployment through the [Azure AI Portal](https://oai.azure.com/portal).\n\nIn Azure, each client must specify a `Deployment Name` to connect to the Azure OpenAI service.\n\nIt's essential to understand that the `Deployment Name` is different from the model you choose to deploy\n\nFor instance, a deployment named 'MyImgAiDeployment' could be configured to use 'gpt-image-1-mini' model.\n\nFor now, to keep things simple, you can create a deployment using the following settings:\n\nDeployment Name: `MyImgAiDeployment`\nModel Name: `gpt-image-1-mini`\n\nThis Azure configuration will align with the default configurations of the Spring Boot Azure AI Starter and its Autoconfiguration feature.\n\nIf you use a different Deployment Name, update the configuration property accordingly:\n\n```\nspring.ai.azure.openai.image.options.deployment-name=<my deployment name>\n```\n\nThe different deployment structures of Azure OpenAI and OpenAI leads to a property in the Azure OpenAI client library named `deploymentOrModelName`.\nThis is because in OpenAI there is no `Deployment Name`, only a `Model Name`.\n\n=== Add Repositories and BOM\n\nSpring AI artifacts are published in Maven Central and Spring Snapshot repositories.\nRefer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system.\n\nTo help with dependency management, Spring AI provides a BOM (bill of materials) to ensure that a consistent version of Spring AI is used throughout the entire project. Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build system.\n\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the Azure OpenAI Chat Client.\nTo enable it add the following dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-azure-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-azure-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n=== Image Generation Properties\n\n[NOTE]\n====\nEnabling and disabling of the image auto-configurations are now configured via top level properties with the prefix `spring.ai.model.image`.\n\nTo enable, spring.ai.model.image=azure-openai (It is enabled by default)\n\nTo disable, spring.ai.model.image=none (or any value which doesn't match azure-openai)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix `spring.ai.azure.openai.image` is the property prefix that lets you configure the `ImageModel` implementation for Azure OpenAI.\n\n[cols=\"3,5,1\"]\n|====\n| Property | Description | Default\n| spring.ai.azure.openai.image.enabled (Removed and no longer valid) | Enable Azure OpenAI image model.  | true\n| spring.ai.model.image | Enable image model.

Check Azure documentation for supported sizes for your model. | -\n| spring.ai.azure.openai.image.options.size_width  | The width of the generated images.  | -\n| spring.ai.azure.openai.image.options.size_height | The height of the generated images.  | -\n| spring.ai.azure.openai.image.options.user        | A unique identifier representing your end-user, which can help Azure OpenAI to monitor and detect abuse. | -\n|====\n\n==== Connection Properties\n\nThe prefix `spring.ai.azure.openai` is used as the property prefix that lets you connect to Azure OpenAI.\n\n[cols=\"3,5,1\"]\n|====\n| Property | Description | Default\n| spring.ai.azure.openai.endpoint   | The URL to connect to (e.g. https://&lt;your-resource&gt;.openai.azure.com/) |  -\n| spring.ai.azure.openai.apiKey    | The API Key           |  -\n|====\n\n== Runtime Options [[image-options]]\n\nThe https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-azure-openai/src/main/java/org/springframework/ai/azure/openai/AzureOpenAiImageOptions.java[AzureOpenAiImageOptions] provides model configurations, such as the deployment name, model, and image size.\n\nOn start-up, the default options can be configured with the `AzureOpenAiImageModel(OpenAIClient openAIClient, AzureOpenAiImageOptions options)` constructor. Alternatively, use the `spring.ai.azure.openai.image.options.*` properties described previously.\n\nAt runtime you can override the default options by adding request-specific options to the `ImagePrompt` call.\nFor example, to use the gpt-image-1-mini model with a custom size:\n\n[source,java]\n----\nImageResponse response = azureOpenAiImageModel.call(\n        new ImagePrompt(\"A light cream colored mini golden doodle\",\n        AzureOpenAiImageOptions.builder()\n                .model(\"gpt-image-1-mini\")\n                .deploymentName(\"gpt-image-1-mini\")\n                .height(1024)\n                .width(1024)\n                .build())\n);\n----\n\nTIP: In addition to the model specific https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-azure-openai/src/main/java/org/springframework/ai/azure/openai/AzureOpenAiImageOptions.java[AzureOpenAiImageOptions] you can use a portable https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/image/ImageOptions.java[ImageOptions] instance, created with the https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/image/ImageOptionsBuilder.java[ImageOptionsBuilder#builder()].\n"

    "content": "[[ImageModel]]\n= Image Model API\n\n\nThe `Spring Image Model API` is designed to be a simple and portable interface for interacting with various xref:concepts.adoc#_models[AI Models] specialized in image generation, allowing developers to switch between different image-related models with minimal code changes.\nThis design aligns with Spring's philosophy of modularity and interchangeability, ensuring developers can quickly adapt their applications to different AI capabilities related to image processing.\n\nAdditionally, with the support of companion classes like `ImagePrompt` for input encapsulation and `ImageResponse` for output handling, the Image Model API unifies the communication with AI Models dedicated to image generation.\nIt manages the complexity of request preparation and response parsing, offering a direct and simplified API interaction for image-generation functionalities.\n\nThe Spring Image Model API is built on top of the Spring AI `Generic Model API`, providing image-specific abstractions and implementations.\n\n== API Overview\n\nThis section provides a guide to the Spring Image Model API interface and associated classes.\n\n== Image Model\n\nHere is the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/image/ImageModel.java[ImageModel] interface definition:\n\n[source,java]\n----\n@FunctionalInterface\npublic interface ImageModel extends Model<ImagePrompt, ImageResponse> {\n\n\tImageResponse call(ImagePrompt request);\n\n}\n----\n\n=== ImagePrompt\n\nThe https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/image/ImagePrompt.java[ImagePrompt] is a `ModelRequest` that encapsulates a list of https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/image/ImageMessage.java[ImageMessage] objects and optional model request options.\nThe following listing shows a truncated version of the `ImagePrompt` class, excluding constructors and other utility methods:\n\n[source,java]\n----\npublic class ImagePrompt implements ModelRequest<List<ImageMessage>> {\n\n    private final List<ImageMessage> messages;\n\n\tprivate ImageOptions imageModelOptions;\n\n    @Override\n\tpublic List<ImageMessage> getInstructions() {...}\n\n\t@Override\n\tpublic ImageOptions getOptions() {...}\n\n    // constructors and utility methods omitted\n}\n----\n\n==== ImageMessage\n\nThe `ImageMessage` class encapsulates the text to use and the weight that the text should have in influencing the generated image.  For models that support weights, they can be positive or negative.\n\n[source,java]\n----\npublic class ImageMessage {\n\n\tprivate String text;\n\n\tprivate Float weight;\n\n    public String getText() {...}\n\n\tpublic Float getWeight() {...}\n\n   // constructors and utility methods omitted\n}\n----\n\n==== ImageOptions\n\nRepresents the options that can be passed to the Image generation model. The `ImageOptions` interface extends the `ModelOptions` interface and is used to define few portable options that can be passed to the AI model.\n\nThe `ImageOptions` interface is defined as follows:\n\n[source,java]\n----\npublic interface ImageOptions extends ModelOptions {\n\n\tInteger getN();\n\n\tString getModel();\n\n\tInteger getWidth();\n\n\tInteger getHeight();\n\n\tString getResponseFormat(); // openai - url or base64 : stability ai byte[] or base64\n\n}\n----\n\nAdditionally, every model specific ImageModel implementation can have its own options that can be passed to the AI model. For example, the OpenAI Image Generation model has its own options like `quality`, `style`, etc.\n\n\nThis is a powerful feature that allows developers to use model specific options when starting the application and then override them at runtime using the `ImagePrompt`.\n\n\n=== ImageResponse\n\nThe structure of the `ImageResponse` class is as follows:\n\n[source,java]\n----\npublic class ImageResponse implements ModelResponse<ImageGeneration> {\n\n\tprivate final ImageResponseMetadata imageResponseMetadata;\n\n\tprivate final List<ImageGeneration> imageGenerations;\n\n\t@Override\n\tpublic ImageGeneration getResult() {\n\t\t// get the first result\n\t}\n\n\t@Override\n\tpublic List<ImageGeneration> getResults() {...}\n\n\t@Override\n\tpublic ImageResponseMetadata getMetadata() {...}\n\n    // other methods omitted\n\n}\n----\n\nThe https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/image/ImageResponse.java[ImageResponse] class holds the AI Model's output, with each `ImageGeneration` instance containing one of potentially multiple outputs resulting from a single prompt.\n\nThe `ImageResponse` class also carries a `ImageResponseMetadata` object holding metadata about the AI Model's response.\n\n=== ImageGeneration\n\nFinally, the https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/image/ImageGeneration.java[ImageGeneration] class extends from the `ModelResult` to represent the output response and related metadata about this result:\n\n[source,java]\n----\npublic class ImageGeneration implements ModelResult<Image> {\n\n\tprivate ImageGenerationMetadata imageGenerationMetadata;\n\n\tprivate Image image;\n\n    @Override\n\tpublic Image getOutput() {...}\n\n\t@Override\n\tpublic ImageGenerationMetadata getMetadata() {...}\n\n    // other methods omitted\n\n}\n----\n\n== Available Implementations\n\n`ImageModel` implementations are provided for the following Model providers:\n\n* xref:api/image/openai-image.adoc[OpenAI Image Generation]\n* xref:api/image/azure-openai-image.adoc[Azure OpenAI Image Generation]\n* xref:api/image/qianfan-image.adoc[QianFan Image Generation]\n* xref:api/image/stabilityai-image.adoc[StabilityAI Image Generation]\n\n== API Docs\n\nYou can find the Javadoc https://docs.spring.io/spring-ai/docs/current-SNAPSHOT/[here].\n\n== Feedback and Contributions\n\nThe project's https://github.com/spring-projects/spring-ai/discussions[GitHub discussions] is a great place to send feedback.\n"

In the example above, valid `clients` values would be: `\"my-server\"`, `\"tool-server\"`, and `\"local-server\"`.\n\n== Usage with MCP Client\n\nThe annotated handlers are automatically integrated with the MCP client:\n\n[source,java]\n----\n@Autowired\nprivate List<McpSyncClient> mcpClients;\n\n// The clients will automatically use your annotated handlers based on clients\n// No manual registration needed - handlers are matched to clients by name\n----\n\nFor each MCP client connection, handlers with matching `clients` will be automatically registered and invoked when the corresponding events occur.\n\n== Additional Resources\n\n* xref:api/mcp/mcp-annotations-overview.adoc[MCP Annotations Overview]\n* xref:api/mcp/mcp-annotations-server.adoc[Server Annotations]\n* xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters]\n* xref:api/mcp/mcp-client-boot-starter-docs.adoc[MCP Client Boot Starter]\n"

    "content": "= MCP Annotations\n\nThe Spring AI MCP Annotations module provides annotation-based method handling for link:https://github.com/modelcontextprotocol/spec[Model Context Protocol (MCP)] servers and clients in Java. \nIt simplifies the creation and registration of MCP server methods and client handlers through a clean, declarative approach using Java annotations.\n\n The MCP Annotations enable developers to create and register MCP operation handlers using declarative annotations.\nThis approach simplifies implementing MCP server and client functionality by reducing boilerplate code and improving maintainability.\n\nThis library builds on top of the link:https://github.com/modelcontextprotocol/java-sdk[MCP Java SDK] to provide a higher-level, annotation-based programming model for implementing MCP servers and clients.\n\n== Architecture\n\nThe MCP Annotations module consists of:\n\n=== Server Annotations\n\nFor MCP Servers, the following annotations are provided:\n\n* `@McpTool` - Implements MCP tools with automatic JSON schema generation\n* `@McpResource` - Provides access to resources via URI templates\n* `@McpPrompt` - Generates prompt messages\n* `@McpComplete` - Provides auto-completion functionality\n\n=== Client Annotations\n\nFor MCP Clients, the following annotations are provided:\n\n* `@McpLogging` - Handles logging message notifications\n* `@McpSampling` - Handles sampling requests\n* `@McpElicitation` - Handles elicitation requests for gathering additional information\n* `@McpProgress` - Handles progress notifications during long-running operations\n* `@McpToolListChanged` - Handles tool list change notifications\n* `@McpResourceListChanged` - Handles resource list change notifications\n* `@McpPromptListChanged` - Handles prompt list change notifications\n\n\n=== Special Parameters and Annotations\n\n* `McpSyncRequestContext` - Special parameter type for synchronous operations that provides a unified interface for accessing MCP request context, including the original request, server exchange (for stateful operations), transport context (for stateless operations), and convenient methods for logging, progress, sampling, elicitation, and roots access. This parameter is automatically injected and excluded from JSON schema generation. **Supported in Complete, Prompt, Resource, and Tool methods.**\n* `McpAsyncRequestContext` - Special parameter type for asynchronous operations that provides the same unified interface as `McpSyncRequestContext` but with reactive (Mono-based) return types. This parameter is automatically injected and excluded from JSON schema generation. **Supported in Complete, Prompt, Resource, and Tool methods.**\n* `McpTransportContext` - Special parameter type for stateless operations that provides lightweight access to transport-level context without full server exchange functionality. This parameter is automatically injected and excluded from JSON schema generation\n* `@McpProgressToken` - Marks a method parameter to receive the progress token from the request. This parameter is automatically injected and excluded from the generated JSON schema. **Note:** When using `McpSyncRequestContext` or `McpAsyncRequestContext`, the progress token can be accessed via `ctx.request().progressToken()` instead of using this annotation.\n* `McpMeta` - Special parameter type that provides access to metadata from MCP requests, notifications, and results. This parameter is automatically injected and excluded from parameter count limits and JSON schema generation. **Note:** When using `McpSyncRequestContext` or `McpAsyncRequestContext`, metadata can be obtained via `ctx.requestMeta()` instead.\n* `MetaProvider` - Interface implemented to supply `_meta` field data for tool, prompt, and resource declarations. Referenced via the `metaProvider` attribute of `@McpTool`, `@McpPrompt`, and `@McpResource`.\n\n== Getting Started\n\n=== Dependencies\n\nAdd the MCP annotations dependency to your project:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-mcp-annotations</artifactId>\n</dependency>\n----\n\nThe MCP annotations are automatically included when you use any of the MCP Boot Starters:\n\n* `spring-ai-starter-mcp-client`\n* `spring-ai-starter-mcp-client-webflux`\n* `spring-ai-starter-mcp-server`\n* `spring-ai-starter-mcp-server-webflux`\n* `spring-ai-starter-mcp-server-webmvc`\n\n=== Configuration\n\nThe annotation scanning is enabled by default when using the MCP Boot Starters. You can configure the scanning behavior using the following properties:\n\n==== Client Annotation Scanner\n\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      client:\n        annotation-scanner:\n          enabled: true  # Enable/disable annotation scanning\n----\n\n==== Server Annotation Scanner\n\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      server:\n        annotation-scanner:\n          enabled: true  # Enable/disable annotation scanning\n----\n\n== Quick Example\n\nHere's a simple example of using MCP annotations to create a calculator tool:\n\n[source,java]\n----\n@Component\npublic class CalculatorTools {\n\n    @McpTool(name = \"add\", description = \"Add two numbers together\")\n    public int add(\n            @McpToolParam(description = \"First number\", required = true) int a,\n            @McpToolParam(description = \"Second number\", required = true) int b) {\n        return a + b;\n    }\n\n    @McpTool(name = \"multiply\", description = \"Multiply two numbers\")\n    public double multiply(\n            @McpToolParam(description = \"First number\", required = true) double x,\n            @McpToolParam(description = \"Second number\", required = true) double y) {\n        return x * y;\n    }\n}\n----\n\nAnd a simple client handler for logging:\n\n[source,java]\n----\n@Component\npublic class LoggingHandler {\n\n    @McpLogging(clients = \"my-server\")\n    public void handleLoggingMessage(LoggingMessageNotification notification) {\n        System.out.println(\"Received log: \" + notification.level() + \n                          \" - \" + notification.data());\n    }\n}\n----\n\nWith Spring Boot auto-configuration, these annotated beans are automatically detected and registered with the MCP server or client.\n\n== Documentation\n\n* xref:api/mcp/mcp-annotations-client.adoc[Client Annotations] - Detailed guide for client-side annotations\n* xref:api/mcp/mcp-annotations-server.adoc[Server Annotations] - Detailed guide for server-side annotations\n* xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters] - Guide for special parameter types\n* xref:api/mcp/mcp-annotations-examples.adoc[Examples] - Comprehensive examples and use cases\n\n== Additional Resources\n\n* xref:api/mcp/mcp-overview.adoc[MCP Overview]\n* xref:api/mcp/mcp-client-boot-starter-docs.adoc[MCP Client Boot Starter]\n* xref:api/mcp/mcp-server-boot-starter-docs.adoc[MCP Server Boot Starter]\n* link:https://modelcontextprotocol.github.io/specification/[Model Context Protocol Specification]\n"

This ensures that only appropriate methods are registered for each server configuration.\nA warning is logged for each filtered method to help with debugging.\n\n=== Synchronous vs Asynchronous Filtering\n\n==== Synchronous Servers\n\nSynchronous servers (configured with `spring.ai.mcp.server.type=SYNC`) use synchronous providers that:\n\n* **Accept** methods with non-reactive return types:\n  - Primitive types (`int`, `double`, `boolean`)\n  - Object types (`String`, `Integer`, custom POJOs)\n  - MCP types (`CallToolResult`, `ReadResourceResult`, `GetPromptResult`, `CompleteResult`)\n  - Collections (`List<String>`, `Map<String, Object>`)\n\n* **Filter out** methods with reactive return types:\n  -

use sync methods for sync servers, async for async servers\n2. **Separate stateful and stateless** implementations into different classes for clarity\n3. **Check logs** during startup for filtered method warnings\n4. **Use the right context** - `McpSyncRequestContext`/`McpAsyncRequestContext` for stateful, `McpTransportContext` for stateless\n5. **Test both modes** if you support both stateful and stateless deployments\n\n== Async Support\n\nAll server annotations support asynchronous implementations using Reactor:\n\n[source,java]\n----\n@Component\npublic class AsyncTools {\n\n    @McpTool(name = \"async-fetch\", description = \"Fetch data asynchronously\")\n    public Mono<String> asyncFetch(\n            @McpToolParam(description = \"URL\", required = true) String url) {\n        \n        return Mono.fromCallable(() -> {\n            // Simulate async operation\n            return fetchFromUrl(url);\n        }).subscribeOn(Schedulers.boundedElastic());\n    }\n\n    @McpResource(uri = \"async-data://{id}\", name = \"Async Data\")\n    public Mono<ReadResourceResult> asyncResource(String id) {\n        return Mono.fromCallable(() -> {\n            String data = loadData(id);\n            return new ReadResourceResult(List.of(\n                new TextResourceContents(\"async-data://\" + id, \"text/plain\", data)\n            ));\n        }).delayElements(Duration.ofMillis(100));\n    }\n}\n----\n\n== Spring Boot Integration\n\nWith Spring Boot auto-configuration, annotated beans are automatically detected and registered:\n\n[source,java]\n----\n@SpringBootApplication\npublic class McpServerApplication {\n    public static void main(String[] args) {\n        SpringApplication.run(McpServerApplication.class, args);\n    }\n}\n\n@Component\npublic class MyMcpTools {\n    // Your @McpTool annotated methods\n}\n\n@Component\npublic class MyMcpResources {\n    // Your @McpResource annotated methods\n}\n----\n\nThe auto-configuration will:\n\n1. Scan for beans with MCP annotations\n2. Create appropriate specifications\n3. Register them with the MCP server\n4.

parameters are automatically injected by the framework and are excluded from JSON schema generation.\n\n== Special Parameter Types\n\n=== MetaProvider\n\nThe `MetaProvider` interface supplies data for the `_meta` field in tool, prompt, and resource declarations.\n\n==== Overview\n\n* Implemented as a class referenced in `@McpTool(metaProvider = ...)`, `@McpPrompt(metaProvider = ...)`, or `@McpResource(metaProvider = ...)`\n* Allows attaching static or computed metadata to a tool/prompt/resource specification at startup\n* The default `DefaultMetaProvider` returns an empty map (no `_meta` appended)\n\n==== Custom MetaProvider\n\n[source,java]\n----\npublic class MyToolMetaProvider implements MetaProvider {\n\n    @Override\n    public Map<String, Object> getMeta() {\n

Automatic Injection\n\nThe following parameters are automatically injected by the framework:\n\n1. `McpMeta` - Metadata from the `_meta` field of the request\n2. `@McpProgressToken String` - Progress token if available\n3. `McpSyncRequestContext` / `McpAsyncRequestContext` - Unified request context (recommended)\n4. `McpSyncServerExchange` / `McpAsyncServerExchange` - Low-level server exchange context (stateful only)\n5. `McpTransportContext` - Transport context for stateless operations\n6. `CallToolRequest` - Full tool request for dynamic schema (tools only)\n\n=== Schema Generation\n\nSpecial parameters are excluded from JSON schema generation:\n\n* They don't appear in the tool's input schema\n* They don't count towards parameter limits\n* They're not visible to MCP clients\n\n=== Null Handling\n\n* `McpMeta` - Never null, empty object if no metadata\n* `@McpProgressToken` - Can be null if no token provided\n* Server exchanges - Never null when properly configured\n* `CallToolRequest` - Never null for tool methods\n\n== Best Practices\n\n=== Use McpMeta for Context\n\n[source,java]\n----\n@McpTool(name = \"context-aware\", description = \"Context-aware tool\")\npublic String contextAware(\n        @McpToolParam(description = \"Data\", required = true) String data,\n        McpMeta meta) {\n    \n    // Always check for null values in metadata\n    String userId = (String) meta.get(\"userId\");\n    if (userId == null) {\n        userId = \"anonymous\";\n    }\n    \n    return processForUser(data, userId);\n}\n----\n\n=== Progress Token Null Checks\n\n[source,java]\n----\n@McpTool(name = \"safe-progress\", description = \"Safe progress handling\")\npublic String safeProgress(\n        @McpProgressToken String progressToken,\n        @McpToolParam(description = \"Task\", required = true) String task,\n        McpSyncServerExchange exchange) {\n    \n    // Always check if progress token is available\n    if (progressToken != null) {\n        exchange.progressNotification(new ProgressNotification(\n            progressToken, 0.0, 1.0, \"Starting\"));\n    }\n    \n    // Perform work...\n    \n    if (progressToken != null) {\n        exchange.progressNotification(new ProgressNotification(\n            progressToken, 1.0, 1.0, \"Complete\"));\n    }\n    \n    return \"Task completed\";\n}\n----\n\n=== Choose the Right Context\n\n* Use `McpSyncRequestContext` / `McpAsyncRequestContext` for unified access to request context, supporting both stateful and stateless operations with convenient helper methods\n* Use `McpTransportContext` for simple stateless operations when you only need transport-level context\n* Omit context parameters entirely for the simplest cases\n\n=== Capability Checking\n\nAlways check capability support before using client features:\n\n[source,java]\n----\n@McpTool(name = \"capability-aware\", description = \"Tool that checks capabilities\")\npublic String capabilityAware(\n        McpSyncRequestContext context,\n        @McpToolParam(description = \"Data\", required = true) String data) {\n    \n    // Check if elicitation is supported before using it\n    if (context.elicitEnabled()) {\n        // Safe to use elicitation\n        var result = context.elicit(UserInfo.class);\n        // Process result...\n    }\n    \n    // Check if sampling is supported before using it\n    if (context.sampleEnabled()) {\n        // Safe to use sampling\n        var samplingResult = context.sample(\"Process: \" + data);\n        // Process result...\n    }\n    \n    // Note: Stateless servers do not support bidirectional operations\n    // (roots, elicitation, sampling) and will return false for these checks\n    \n    return \"Processed with capability awareness\";\n}\n----\n\n== Additional Resources\n\n* xref:api/mcp/mcp-annotations-overview.adoc[MCP Annotations Overview]\n* xref:api/mcp/mcp-annotations-server.adoc[Server Annotations]\n*

    "content": "= MCP Client Boot Starter\n\nThe Spring AI MCP (Model Context Protocol) Client Boot Starter provides auto-configuration for MCP client functionality in Spring Boot applications.\nIt supports both synchronous and asynchronous client implementations with various transport options.\n\nThe MCP Client Boot Starter provides:\n\n* Management of multiple client instances\n* Automatic client initialization (if enabled)\n* Support for multiple named transports (STDIO, Http/SSE and Streamable HTTP)\n* Integration with Spring AI's tool execution framework\n* Tool filtering capabilities for selective tool inclusion/exclusion\n* Customizable tool name prefix generation for avoiding naming conflicts\n* Proper lifecycle management with automatic cleanup of resources when the application context is closed\n* Customizable client creation through customizers\n\n== Starters\n\n=== Standard MCP Client\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-mcp-client</artifactId>\n</dependency>\n----\n\nThe standard starter connects simultaneously to one or more MCP servers over `STDIO` (in-process), `SSE`, `Streamable-HTTP` and `Stateless Streamable-HTTP` transports.\nThe SSE and Streamable-Http transports use the JDK HttpClient-based transport implementation.\nEach connection to an MCP server creates a new MCP client instance.\nYou can choose either `SYNC` or `ASYNC` MCP clients (note: you cannot mix sync and async clients).\nFor production deployment, we recommend using the WebFlux-based SSE & StreamableHttp connection with the `spring-ai-starter-mcp-client-webflux`.\n\n=== WebFlux Client\n\nThe WebFlux starter provides similar functionality to the standard starter but uses a WebFlux-based Streamable-Http, Stateless Streamable-Http and SSE transport implementation.\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-mcp-client-webflux</artifactId>\n</dependency>\n----\n\n== Configuration Properties\n\n=== Common Properties\n\nThe common properties are prefixed with `spring.ai.mcp.client`:\n\n[cols=\"3,4,3\"]\n|===\n|Property |Description |Default Value\n\n|`enabled`\n|Enable/disable the MCP client\n|`true`\n\n|`name`\n|Name of the MCP client instance\n|`spring-ai-mcp-client`\n\n|`version`\n|Version of the MCP client instance\n|`1.0.0`\n\n|`initialized`\n|Whether to initialize clients on creation\n|`true`\n\n|`request-timeout`\n|Timeout duration for MCP client requests\n|`20s`\n\n|`type`\n|Client type (SYNC or ASYNC). All clients must be either sync or async; mixing is not supported\n|`SYNC`\n\n|`root-change-notification`\n|Enable/disable root change notifications for all clients\n|`true`\n\n|`toolcallback.enabled`\n|Enable/disable the MCP tool callback integration with Spring AI's tool execution framework\n|`true`\n|===\n\n=== MCP Annotations Properties\n\nMCP Client Annotations provide a declarative way to implement MCP client handlers using Java annotations.\nThe client mcp-annotations properties are prefixed with `spring.ai.mcp.client.annotation-scanner`:\n\n[cols=\"3,4,3\"]\n|===\n|Property |Description |Default Value\n\n|`enabled`\n|Enable/disable the MCP client annotations auto-scanning\n|`true`\n|===\n\n=== Stdio Transport Properties\n\nProperties for Standard I/O transport are prefixed with `spring.ai.mcp.client.stdio`:\n\n[cols=\"3,4,3\"]\n|===\n|Property |Description |Default Value\n\n|`servers-configuration`\n|Resource containing the MCP servers configuration in JSON format\n|-\n\n|`connections`\n|Map of named stdio connection configurations\n|-\n\n|`connections.[name].command`\n|The command to execute for the MCP server\n|-\n\n|`connections.[name].args`\n|List of command arguments\n|-\n\n|`connections.[name].env`\n|Map of environment variables for the server process\n|-\n|===\n\nExample configuration:\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      client:\n        stdio:\n          root-change-notification: true\n          connections:\n            server1:\n              command: /path/to/server\n              args:\n                - --port=8080\n                - --mode=production\n              env:\n                API_KEY: your-api-key\n                DEBUG: \"true\"\n----\n\nAlternatively, you can configure stdio connections using an external JSON file using the link:https://modelcontextprotocol.io/quickstart/user[Claude Desktop format]:\n\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      client:\n        stdio:\n          servers-configuration: classpath:mcp-servers.json\n----\n\nThe Claude Desktop format looks like this:\n\n[source,json]\n----\n{\n  \"mcpServers\": {\n    \"filesystem\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@modelcontextprotocol/server-filesystem\",\n        \"/Users/username/Desktop\",\n        \"/Users/username/Downloads\"\n      ]\n    }\n  }\n}\n----\n\n=== Windows STDIO Configuration\n\nIMPORTANT: On Windows, commands like `npx`, `npm`, and `node` are implemented as **batch files** (`.cmd`), not native executables. Java's `ProcessBuilder` cannot execute batch files directly and requires the `cmd.exe /c` wrapper.\n\n==== Why Windows Needs Special Handling\n\nWhen Java's `ProcessBuilder` (used internally by `StdioClientTransport`) attempts to spawn a process on Windows, it can only execute:\n\n* Native executables (`.exe` files)\n* System commands available to `cmd.exe`\n\nWindows batch files like `npx.cmd`, `npm.cmd`, and even `python.cmd` (from the Microsoft Store) require the `cmd.exe` shell to execute them.\n\n==== Solution: cmd.exe Wrapper\n\nWrap batch file commands with `cmd.exe /c`:\n\n**Windows Configuration:**\n[source,json]\n----\n{\n  \"mcpServers\": {\n    \"filesystem\": {\n      \"command\": \"cmd.exe\",\n      \"args\": [\n        \"/c\",\n        \"npx\",\n        \"-y\",\n        \"@modelcontextprotocol/server-filesystem\",\n        \"C:\\\\Users\\\\username\\\\Desktop\"\n      ]\n    }\n  }\n}\n----\n\n**Linux/macOS Configuration:**\n[source,json]\n----\n{\n  \"mcpServers\": {\n    \"filesystem\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@modelcontextprotocol/server-filesystem\",\n        \"/Users/username/Desktop\"\n      ]\n    }\n  }\n}\n----\n\n==== Cross-Platform Programmatic Configuration\n\nFor applications that need to work across platforms without separate configuration files, use OS detection in your Spring Boot application:\n\n[source,java]\n----\n@Bean(destroyMethod = \"close\")\n@ConditionalOnMissingBean(McpSyncClient.class)\npublic McpSyncClient mcpClient() {\n    ServerParameters stdioParams;\n\n    if (isWindows()) {\n        // Windows: cmd.exe /c npx approach\n        var winArgs = new ArrayList<>(Arrays.asList(\n            \"/c\", \"npx\", \"-y\", \"@modelcontextprotocol/server-filesystem\", \"target\"));\n        stdioParams = ServerParameters.builder(\"cmd.exe\")\n                .args(winArgs)\n                .build();\n    } else {\n        // Linux/Mac: direct npx approach\n        stdioParams = ServerParameters.builder(\"npx\")\n                .args(\"-y\", \"@modelcontextprotocol/server-filesystem\", \"target\")\n                .build();\n    }\n\n    return McpClient.sync(new StdioClientTransport(stdioParams, McpJsonDefaults.getMapper()))\n            .requestTimeout(Duration.ofSeconds(10))\n            .build()\n            .initialize();\n}\n\nprivate static boolean isWindows() {\n    return System.getProperty(\"os.name\").toLowerCase().contains(\"win\");\n}\n----\n\nNOTE: When using programmatic configuration with `@Bean`, add `@ConditionalOnMissingBean(McpSyncClient.class)` to avoid conflicts with auto-configuration from JSON files.\n\n==== Path Considerations\n\n**Relative paths** (recommended for portability):\n[source,json]\n----\n{\n  \"command\": \"cmd.exe\",\n  \"args\": [\"/c\", \"npx\", \"-y\", \"@modelcontextprotocol/server-filesystem\", \"target\"]\n}\n----\n\nThe MCP server resolves relative paths based on the application's working directory.\n\n**Absolute paths** (Windows requires backslashes or escaped forward slashes):\n[source,json]\n----\n{\n  \"command\": \"cmd.exe\",\n  \"args\": [\"/c\", \"npx\", \"-y\", \"@modelcontextprotocol/server-filesystem\", \"C:\\\\Users\\\\username\\\\project\\\\target\"]\n}\n----\n\n==== Common Windows Batch Files Requiring cmd.exe\n\n* `npx.cmd`, `npm.cmd` - Node package managers\n* `python.cmd` - Python (Microsoft Store installation)\n* `pip.cmd` - Python package manager\n* `mvn.cmd` - Maven wrapper\n* `gradle.cmd` - Gradle wrapper\n* Custom `.cmd` or `.bat` scripts\n\n==== Reference Implementation\n\nSee link:https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol/filesystem[Spring AI Examples - Filesystem] for a complete cross-platform MCP client implementation that automatically detects the OS and configures the client appropriately.\n\n=== Streamable-HTTP Transport Properties\n\nUsed for connecting to Streamable-HTTP and Stateless Streamable-HTTP MCP servers.\n\nProperties for Streamable-HTTP transport are prefixed with `spring.ai.mcp.client.streamable-http`:\n\n[cols=\"3,4,3\"]\n|===\n|Property |Description | Default Value\n\n|`connections`\n|Map of named Streamable-HTTP connection configurations\n|-\n\n|`connections.[name].url`\n|Base URL endpoint for Streamable-Http communication with the MCP server\n|-\n\n|`connections.[name].endpoint`\n|the streamable-http endpoint (as url suffix) to use for the connection\n|`/mcp`\n|===\n\nExample configuration:\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      client:\n        streamable-http:\n          connections:\n            server1:\n              url: http://localhost:8080\n            server2:\n              url: http://otherserver:8081\n              endpoint: /custom-sse\n----\n\n=== SSE Transport Properties\n\nProperties for Server-Sent Events (SSE) transport are prefixed with `spring.ai.mcp.client.sse`:\n\n[cols=\"3,4,3\"]\n|===\n|Property |Description | Default Value\n\n|`connections`\n|Map of named SSE connection configurations\n|-\n\n|`connections.[name].url`\n|Base URL endpoint for SSE communication with the MCP server\n|-\n\n|`connections.[name].sse-endpoint`\n|the sse endpoint (as url suffix) to use for the connection\n|`/sse`\n|===\n\nExample configurations:\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      client:\n        sse:\n          connections:\n            # Simple configuration using default /sse endpoint\n            server1:\n              url: http://localhost:8080\n            # Custom SSE endpoint\n            server2:\n              url: http://otherserver:8081\n              sse-endpoint: /custom-sse\n            # Complex URL with path and token (like MCP Hub)\n            mcp-hub:\n              url: http://localhost:3000\n              sse-endpoint: /mcp-hub/sse/cf9ec4527e3c4a2cbb149a85ea45ab01\n            # SSE endpoint with query parameters\n            api-server:\n              url: https://api.example.com\n              sse-endpoint: /v1/mcp/events?token=abc123&format=json\n----\n\n==== URL Splitting Guidelines\n\nWhen you have a full SSE URL, split it into base URL and endpoint path:\n\n[cols=\"2,2\"]\n|===\n|Full URL |Configuration\n\n|`\\http://localhost:3000/mcp-hub/sse/token123`\n|`url: http://localhost:3000` +\n`sse-endpoint: /mcp-hub/sse/token123`\n\n|`\\https://api.service.com/v2/events?key=secret`\n|`url: https://api.service.com` +\n`sse-endpoint: /v2/events?key=secret`\n\n|`\\http://localhost:8080/sse`\n|`url: http://localhost:8080` +\n`sse-endpoint: /sse` (or omit for default)\n|===\n\n==== Troubleshooting SSE Connections\n\n*404 Not Found Errors:*\n\n* Verify URL splitting: ensure the base `url` contains only the scheme, host, and port\n* Check the `sse-endpoint` starts with `/` and includes the full path and query parameters\n* Test the full URL directly in a browser or curl to confirm it's accessible\n\n=== Streamable Http Transport Properties\n\nProperties for Streamable Http transport are prefixed with `spring.ai.mcp.client.streamable-http`:\n\n[cols=\"3,4,3\"]\n|===\n|Property |Description | Default Value\n\n|`connections`\n|Map of named Streamable Http connection configurations\n|-\n\n|`connections.[name].url`\n|Base URL endpoint for Streamable-Http communication with the MCP server\n|-\n\n|`connections.[name].endpoint`\n|the streamable-http endpoint (as url suffix) to use for the connection\n|`/mcp`\n|===\n\nExample configuration:\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      client:\n        streamable-http:\n          connections:\n            server1:\n              url: http://localhost:8080\n            server2:\n              url: http://otherserver:8081\n              endpoint: /custom-sse\n----\n\n== Features\n\n=== Sync/Async Client Types\n\nThe starter supports two types of clients:\n\n* Synchronous - default client type (`spring.ai.mcp.client.type=SYNC`), suitable for traditional request-response patterns with blocking operations\n\n**NOTE:** The SYNC client will register only synchronous MCP annotated methods. Asynchronous methods will be ignored.\n\n* Asynchronous - suitable for reactive applications with non-blocking operations, configured using `spring.ai.mcp.client.type=ASYNC`\n\n**NOTE:** The ASYNC client will register only asynchronous MCP annotated methods. Synchronous methods will be ignored.\n\n=== Client Customization\n\nThe auto-configuration provides extensive client spec customization capabilities through callback interfaces. These customizers allow you to configure various aspects of the MCP client behavior, from request timeouts to event handling and message processing.\n\n==== Customization Types\n\nThe following customization options are available:\n\n* *Request Configuration* - Set custom request timeouts\n* link:https://modelcontextprotocol.io/specification/2025-06-18/client/sampling[*Custom Sampling Handlers*] - standardized way for servers to request LLM sampling (`completions` or `generations`) from LLMs via clients. This flow allows clients to maintain control over model access, selection, and permissions while enabling servers to leverage AI capabilities — with no server API keys necessary.\n* link:https://modelcontextprotocol.io/specification/2025-06-18/client/roots[*File system (Roots) Access*] - standardized way for clients to expose filesystem `roots` to servers.\nRoots define the boundaries of where servers can operate within the filesystem, allowing them to understand which directories and files they have access to.\nServers can request the list of roots from supporting clients and receive notifications when that list changes.\n* link:https://modelcontextprotocol.io/specification/2025-06-18/client/elicitation[*Elicitation Handlers*] - standardized way for servers to request additional information from users through the client during interactions.\n* *Event Handlers*  - client's handler to be notified when a certain server event occurs:\n  -

link:https://modelcontextprotocol.io/specification/2025-06-18/basic/utilities/progress[*Progress Handlers*] - standardized way for servers to send structured progress messages to clients.\n\nClients can control logging verbosity by setting minimum log levels\n\n\n==== Client Customization Example\n\nYou can implement `McpCustomizer<McpClient.SyncSpec>` for synchronous clients or `McpCustomizer<McpClient.AsyncSpec>` for asynchronous clients, depending on your application's needs.\n\n[tabs]\n======\nSync::\n+\n[source,java]\n----\n@Component\npublic class CustomMcpSyncClientCustomizer implements McpCustomizer<McpClient.SyncSpec> {\n    @Override\n    public void customize(String serverConfigurationName, McpClient.SyncSpec spec) {\n\n        // Customize the request timeout configuration\n        spec.requestTimeout(Duration.ofSeconds(30));\n\n        // Sets the root URIs that this client can access.\n        spec.roots(roots);\n\n        // Sets a custom sampling handler for processing message creation requests.\n        spec.sampling((CreateMessageRequest messageRequest) -> {\n            // Handle sampling\n            CreateMessageResult result = ...\n            return result;\n        });\n\n        // Sets a custom elicitation handler for processing elicitation requests.\n        spec.elicitation((ElicitRequest request) -> {\n          // handle elicitation\n          return new ElicitResult(ElicitResult.Action.ACCEPT, Map.of(\"message\", request.message()));\n        });\n\n        // Adds a consumer to be notified when progress notifications are received.\n        spec.progressConsumer((ProgressNotification progress) -> {\n         // Handle progress notifications\n        });\n\n        // Adds a consumer to be notified when the available tools change, such as tools\n        // being added or removed.\n        spec.toolsChangeConsumer((List<McpSchema.Tool> tools) -> {\n            // Handle tools change\n        });\n\n        // Adds a consumer to be notified when the available resources change, such as resources\n        // being added or removed.\n        spec.resourcesChangeConsumer((List<McpSchema.Resource> resources) -> {\n            // Handle resources change\n        });\n\n        // Adds a consumer to be notified when the available prompts change, such as prompts\n        // being added or removed.\n        spec.promptsChangeConsumer((List<McpSchema.Prompt> prompts) -> {\n            // Handle prompts change\n        });\n\n        // Adds a consumer to be notified when logging messages are received from the server.\n        spec.loggingConsumer((McpSchema.LoggingMessageNotification log) -> {\n            // Handle log messages\n        });\n    }\n}\n----\n\nAsync::\n+\n[source,java]\n----\n@Component\npublic class CustomMcpAsyncClientCustomizer implements McpCustomizer<McpClient.AsyncSpec> {\n    @Override\n    public void customize(String serverConfigurationName, McpClient.AsyncSpec spec) {\n        // Customize the async client configuration\n        spec.requestTimeout(Duration.ofSeconds(30));\n    }\n}\n----\n======\nThe `serverConfigurationName` parameter is the name of the server configuration that the customizer is being applied to and the MCP Client is created for.\n\nThe MCP client auto-configuration automatically detects and applies any customizers found in the application context.\n\n=== Transport Support\n\nThe auto-configuration supports multiple transport types:\n\n* Standard I/O (Stdio) (activated by the `spring-ai-starter-mcp-client` and `spring-ai-starter-mcp-client-webflux`)\n* (HttpClient) HTTP/SSE and Streamable-HTTP (activated by the `spring-ai-starter-mcp-client`)\n* (WebFlux) HTTP/SSE and Streamable-HTTP (activated by the `spring-ai-starter-mcp-client-webflux`)\n\n=== Tool Filtering\n\nThe MCP Client Boot Starter supports filtering of discovered tools through the `McpToolFilter` interface. This allows you to selectively include or exclude tools based on custom criteria such as the MCP connection information or tool properties.\n\nTo implement tool filtering, create a bean that implements the `McpToolFilter` interface:\n\n[source,java]\n----\n@Component\npublic class CustomMcpToolFilter implements McpToolFilter {\n\n    @Override\n    public boolean test(McpConnectionInfo connectionInfo, McpSchema.Tool tool) {\n        // Filter logic based on connection information and tool properties\n        // Return true to include the tool, false to exclude it\n\n        // Example: Exclude tools from a specific client\n        if (connectionInfo.clientInfo().name().equals(\"restricted-client\")) {\n            return false;\n        }\n\n        // Example: Only include tools with specific names\n        if (tool.name().startsWith(\"allowed_\")) {\n            return true;\n        }\n\n        // Example: Filter based on tool description or other properties\n        if (tool.description() != null &&\n            tool.description().contains(\"experimental\")) {\n            return false;\n        }\n\n        return true; // Include all other tools by default\n    }\n}\n----\n\nThe `McpConnectionInfo` record provides access to:\n\n* `clientCapabilities` - The capabilities of the MCP client\n* `clientInfo` - Information about the MCP client (name and version)\n* `initializeResult` - The initialization result from the MCP server\n\nThe filter is automatically detected and applied to both synchronous and asynchronous MCP tool callback providers.\nIf no custom filter is provided, all discovered tools are included by default.\n\nNote: Only one `McpToolFilter` bean should be defined in the application context.\nIf multiple filters are needed, combine them into a single composite filter implementation.\n\n=== Tool Name Prefix Generation\n\nThe MCP Client Boot Starter supports customizable tool name prefix generation through the `McpToolNamePrefixGenerator` interface. This feature helps avoid naming conflicts when integrating tools from multiple MCP servers by adding unique prefixes to tool names.\n\nBy default, if no custom `McpToolNamePrefixGenerator` bean is provided, the starter uses `DefaultMcpToolNamePrefixGenerator` which ensures unique tool names across all MCP client connections. The default generator:\n\n* Tracks all existing connections and tool names to ensure uniqueness\n* Formats tool names by replacing non-alphanumeric characters with underscores (e.g., `my-tool` becomes `my_tool`)\n* When duplicate tool names are detected across different connections, adds a counter prefix (e.g., `alt_1_toolName`, `alt_2_toolName`)\n* Is thread-safe and maintains idempotency - the same combination of (client, server, tool) always gets the same unique name\n* Ensures the final name doesn't exceed 64 characters (truncating from the beginning if necessary)\n\nFor example:\n* First occurrence of tool `search` → `search`\n* Second occurrence of tool `search` from a different connection → `alt_1_search`\n* Tool with special characters `my-special-tool` → `my_special_tool`\n\nYou can customize this behavior by providing your own implementation:\n\n[source,java]\n----\n@Component\npublic class CustomToolNamePrefixGenerator implements McpToolNamePrefixGenerator {\n\n    @Override\n    public String prefixedToolName(McpConnectionInfo connectionInfo, Tool tool) {\n        // Custom logic to generate prefixed tool names\n\n        // Example: Use server name and version as prefix\n        String serverName = connectionInfo.initializeResult().serverInfo().name();\n        String serverVersion = connectionInfo.initializeResult().serverInfo().version();\n        return serverName + \"_v\" + serverVersion.replace(\".\", \"_\") + \"_\" + tool.name();\n    }\n}\n----\n\nThe `McpConnectionInfo` record provides comprehensive information about the MCP connection:\n\n* `clientCapabilities` - The capabilities of the MCP client\n* `clientInfo` - Information about the MCP client (name, title, and version)\n* `initializeResult` - The initialization result from the MCP server, including server information\n\n==== Built-in Prefix Generators\n\nThe framework provides several built-in prefix generators:\n\n* `DefaultMcpToolNamePrefixGenerator` - Ensures unique tool names by tracking duplicates and adding counter prefixes when needed (used by default if no custom bean is provided)\n* `McpToolNamePrefixGenerator.noPrefix()` - Returns tool names without any prefix (may cause conflicts if multiple servers provide tools with the same name)\n\nTo disable prefixing entirely and use raw tool names (not recommended if using multiple MCP servers), register the no-prefix generator as a bean:\n\n[source,java]\n----\n@Configuration\npublic class McpConfiguration {\n\n    @Bean\n    public McpToolNamePrefixGenerator mcpToolNamePrefixGenerator() {\n        return McpToolNamePrefixGenerator.noPrefix();\n    }\n}\n----\n\nThe prefix generator is automatically detected and applied to both synchronous and asynchronous MCP tool callback providers through Spring's `ObjectProvider` mechanism.\nIf no custom generator bean is provided, the `DefaultMcpToolNamePrefixGenerator` is used automatically.\n\nWARNING: When using `McpToolNamePrefixGenerator.noPrefix()` with multiple MCP servers, duplicate tool names will cause an `IllegalStateException`. The default `DefaultMcpToolNamePrefixGenerator` prevents this by automatically adding unique prefixes to duplicate tool names.\n\n=== Tool Context to MCP Meta Converter\n\nThe MCP Client Boot Starter supports customizable conversion of Spring AI's xref:api/tools.adoc#_tool_context[ToolContext] to MCP tool-call metadata through the `ToolContextToMcpMetaConverter` interface.\nThis feature allows you to pass additional contextual information (e.g. user id, secrets token) as metadata along with the LLM's generated call arguments.\n\nFor example you can pass the MCP `progressToken` to your link:https://modelcontextprotocol.io/specification/2025-06-18/basic/utilities/progress#progress-flow[MCP Progress Flow] in the tool context to track the progress of long-running operations:\n\n[source,java]\n----\nChatModel chatModel = ...\n\nString response = ChatClient.create(chatModel)\n        .prompt(\"Tell me more about the customer with ID 42\")\n        .toolContext(Map.of(\"progressToken\", \"my-progress-token\"))\n        .call()\n        .content();\n----\n\nBy default, if no custom converter bean is provided, the starter uses `ToolContextToMcpMetaConverter.defaultConverter()` which:\n\n* Filters out the MCP exchange key (`McpToolUtils.TOOL_CONTEXT_MCP_EXCHANGE_KEY`)\n* Filters out entries with null values\n* Passes through all other context entries as metadata\n\n\n\n\nYou can customize this behavior by providing your own implementation:\n\n[source,java]\n----\n@Component\npublic class CustomToolContextToMcpMetaConverter implements ToolContextToMcpMetaConverter {\n\n    @Override\n    public Map<String, Object> convert(ToolContext toolContext) {\n        if (toolContext == null || toolContext.getContext() == null) {\n            return Map.of();\n        }\n\n        // Custom logic to convert tool context to MCP metadata\n        Map<String, Object> metadata = new HashMap<>();\n\n        // Example: Add custom prefix to all keys\n        for (Map.Entry<String, Object> entry : toolContext.getContext().entrySet()) {\n            if (entry.getValue() != null) {\n                metadata.put(\"app_\" + entry.getKey(), entry.getValue());\n            }\n        }\n\n        // Example: Add additional metadata\n        metadata.put(\"timestamp\", System.currentTimeMillis());\n        metadata.put(\"source\", \"spring-ai\");\n\n        return metadata;\n    }\n}\n----\n\n==== Built-in Converters\n\nThe framework provides built-in converters:\n\n* `ToolContextToMcpMetaConverter.defaultConverter()` - Filters out MCP exchange key and null values (used by default if no custom bean is provided)\n* `ToolContextToMcpMetaConverter.noOp()` - Returns an empty map, effectively disabling context-to-metadata conversion\n\nTo disable context-to-metadata conversion entirely:\n\n[source,java]\n----\n@Configuration\npublic class McpConfiguration {\n\n    @Bean\n    public ToolContextToMcpMetaConverter toolContextToMcpMetaConverter() {\n        return ToolContextToMcpMetaConverter.noOp();\n    }\n}\n----\n\nThe converter is automatically detected and applied to both synchronous and asynchronous MCP tool callbacks through Spring's `ObjectProvider` mechanism.\nIf no custom converter bean is provided, the default converter is used automatically.\n\n=== Disable the MCP ToolCallback Auto-Configuration\n\nThe MCP ToolCallback auto-configuration is enabled by default, but can be disabled with the `spring.ai.mcp.client.toolcallback.enabled=false` property.\n\nWhen disabled, no `ToolCallbackProvider` bean is created from the available MCP tools.\n\n== MCP Client Annotations\n\nThe MCP Client Boot Starter automatically detects and registers annotated methods for handling various MCP client operations:\n\n* *@McpLogging* - Handles logging message notifications from MCP servers\n* *@McpSampling* - Handles sampling requests from MCP servers for LLM completions\n* *@McpElicitation* - Handles elicitation requests to gather additional information from users\n* *@McpProgress* - Handles progress notifications for long-running operations\n* *@McpToolListChanged* - Handles notifications when the server's tool list changes\n* *@McpResourceListChanged* - Handles notifications when the server's resource list changes\n* *@McpPromptListChanged* - Handles notifications when the server's prompt list changes\n\nExample usage:\n\n[source,java]\n----\n@Component\npublic class McpClientHandlers {\n\n    @McpLogging(clients = \"server1\")\n    public void handleLoggingMessage(LoggingMessageNotification notification) {\n        System.out.println(\"Received log: \" + notification.level() +\n                          \" - \" + notification.data());\n    }\n\n    @McpSampling(clients = \"server1\")\n    public CreateMessageResult handleSamplingRequest(CreateMessageRequest request) {\n        // Process the request and generate a response\n        String response = generateLLMResponse(request);\n\n        return CreateMessageResult.builder()\n            .role(Role.ASSISTANT)\n            .content(new TextContent(response))\n            .model(\"gpt-4\")\n            .build();\n    }\n\n    @McpProgress(clients = \"server1\")\n    public void handleProgressNotification(ProgressNotification notification) {\n        double percentage = notification.progress() * 100;\n        System.out.println(String.format(\"Progress: %.2f%% - %s\",\n            percentage, notification.message()));\n    }\n\n    @McpToolListChanged(clients = \"server1\")\n    public void handleToolListChanged(List<McpSchema.Tool> updatedTools) {\n        System.out.println(\"Tool list updated: \" + updatedTools.size() + \" tools available\");\n        // Update local tool registry\n        toolRegistry.updateTools(updatedTools);\n    }\n}\n----\n\nThe annotations support both synchronous and asynchronous implementations, and can be configured for specific clients using the `clients` parameter:\n\n[source,java]\n----\n@McpLogging(clients = \"server1\")\npublic void handleServer1Logs(LoggingMessageNotification notification) {\n    // Handle logs from specific server\n    logToFile(\"server1.log\", notification);\n}\n\n@McpSampling(clients = \"server1\")\npublic Mono<CreateMessageResult> handleAsyncSampling(CreateMessageRequest request) {\n    return Mono.fromCallable(() -> {\n        String response = generateLLMResponse(request);\n        return CreateMessageResult.builder()\n            .role(Role.ASSISTANT)\n            .content(new TextContent(response))\n            .model(\"gpt-4\")\n            .build();\n    }).subscribeOn(Schedulers.boundedElastic());\n}\n----\n\nFor detailed information about all available annotations and their usage patterns, see the xref:api/mcp/mcp-annotations-client.adoc[MCP Client Annotations] documentation.\n\n== Usage Example\n\nAdd the appropriate starter dependency to your project and configure the client in `application.properties` or `application.yml`:\n\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      client:\n        enabled: true\n        name: my-mcp-client\n        version: 1.0.0\n        request-timeout: 30s\n        type: SYNC  # or ASYNC for reactive applications\n        sse:\n          connections:\n            server1:\n              url: http://localhost:8080\n            server2:\n              url: http://otherserver:8081\n        streamable-http:\n          connections:\n            server3:\n              url: http://localhost:8083\n              endpoint: /mcp\n        stdio:\n          root-change-notification: false\n          connections:\n            server1:\n              command: /path/to/server\n              args:\n                -

It implements the client-side of the protocol, handling:\n\n* Protocol version negotiation to ensure compatibility with servers\n* Capability negotiation to determine available features\n* Message transport and JSON-RPC communication\n* Tool discovery and execution\n* Resource access and management\n* Prompt system interactions\n* Optional features:\n** Roots management\n** Sampling support\n* Synchronous and asynchronous operations\n* Transport options:\n** Stdio-based transport for process-based communication\n** Java HttpClient-based SSE client transport\n** WebFlux SSE client transport for reactive HTTP streaming\n\n^a| image::mcp/java-mcp-client-architecture.jpg[Java MCP Client Architecture, width=500]\n|===\n\n|===\n| link:https://modelcontextprotocol.io/sdk/java/mcp-server[MCP Server] |\n\na| The MCP Server is a foundational component in the Model Context Protocol (MCP) architecture that provides tools, resources, and capabilities to clients. It implements the server-side of the protocol, responsible for:\n\n* Server-side protocol operations implementation\n** Tool exposure and discovery\n** Resource management with URI-based access\n** Prompt template provision and handling\n** Capability negotiation with clients\n** Structured logging and notifications\n* Concurrent client connection management\n* Synchronous and Asynchronous API support\n* Transport implementations:\n** Stdio, Streamable-HTTP, Stateless Streamable-HTTP, SSE\n\n^a| image::mcp/java-mcp-server-architecture.jpg[Java MCP Server Architecture, width=600]\n|===\n\nFor detailed implementation guidance, using the low-level MCP Client/Server APIs, refer to the link:https://modelcontextprotocol.io/sdk/java/mcp-overview[MCP Java SDK documentation].\nFor simplified setup using Spring Boot, use the MCP Boot Starters described below.\n\n== Spring AI MCP Integration\n\nSpring AI provides MCP integration through the following Spring Boot starters:\n\n=== link:mcp-client-boot-starter-docs.html[Client Starters]\n\n* `spring-ai-starter-mcp-client` - Core starter providing `STDIO`, Servlet-based `Streamable-HTTP`, `Stateless Streamable-HTTP` and `SSE` support\n* `spring-ai-starter-mcp-client-webflux` - WebFlux-based  `Streamable-HTTP`, `Stateless Streamable-HTTP` and `SSE` transport implementation\n\n=== link:mcp-server-boot-starter-docs.html[Server Starters]\n\n==== STDIO\n\n[options=\"header\"]\n|===\n|Server Type | Dependency | Property\n| xref:api/mcp/mcp-stdio-sse-server-boot-starter-docs.adoc[Standard Input/Output (STDIO)] | `spring-ai-starter-mcp-server` | `spring.ai.mcp.server.stdio=true`\n|===\n\n==== WebMVC\n\n|===\n|Server Type | Dependency | Property\n| xref:api/mcp/mcp-stdio-sse-server-boot-starter-docs.adoc#_sse_webmvc_serve[SSE WebMVC] | `spring-ai-starter-mcp-server-webmvc` | `spring.ai.mcp.server.protocol=SSE` or empty\n| xref:api/mcp/mcp-streamable-http-server-boot-starter-docs.adoc#_streamable_http_webmvc_server[Streamable-HTTP WebMVC] | `spring-ai-starter-mcp-server-webmvc` | `spring.ai.mcp.server.protocol=STREAMABLE`\n| xref:api/mcp/mcp-stateless-server-boot-starter-docs.adoc#_stateless_webmvc_server[Stateless Streamable-HTTP WebMVC] | `spring-ai-starter-mcp-server-webmvc` | `spring.ai.mcp.server.protocol=STATELESS`\n|===\n\n==== WebMVC (Reactive)\n|===\n|Server Type | Dependency | Property\n| xref:api/mcp/mcp-stdio-sse-server-boot-starter-docs.adoc#_sse_webflux_serve[SSE WebFlux] | `spring-ai-starter-mcp-server-webflux` | `spring.ai.mcp.server.protocol=SSE` or empty\n| xref:api/mcp/mcp-streamable-http-server-boot-starter-docs.adoc#_streamable_http_webflux_server[Streamable-HTTP WebFlux] | `spring-ai-starter-mcp-server-webflux` | `spring.ai.mcp.server.protocol=STREAMABLE`\n| xref:api/mcp/mcp-stateless-server-boot-starter-docs.adoc#_stateless_webflux_server[Stateless Streamable-HTTP WebFlux] | `spring-ai-starter-mcp-server-webflux` | `spring.ai.mcp.server.protocol=STATELESS`\n|===\n\n== xref:api/mcp/mcp-annotations-overview.adoc[Spring AI MCP Annotations]\n\nIn addition to the programmatic MCP client & server configuration, Spring AI provides annotation-based method handling for MCP servers and clients through the xref:api/mcp/mcp-annotations-overview.adoc[MCP Annotations] module. \nThis approach simplifies the creation and registration of MCP operations using a clean, declarative programming model with Java annotations.\n\nThe MCP Annotations module enables developers to:\n\n* Create MCP tools, resources, and prompts using simple annotations\n* Handle client-side notifications and requests declaratively\n* Reduce boilerplate code and improve maintainability\n* Automatically generate JSON schemas for tool parameters\n* Access special parameters and context information\n\nKey features include:   \n\n* xref:api/mcp/mcp-annotations-server.adoc[Server Annotations]: `@McpTool`, `@McpResource`, `@McpPrompt`, `@McpComplete`\n* xref:api/mcp/mcp-annotations-client.adoc[Client Annotations]: `@McpLogging`, `@McpSampling`, `@McpElicitation`, `@McpProgress`\n* xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters]: `McpSyncServerExchange`, `McpAsyncServerExchange`, `McpTransportContext`, `McpMeta`\n* *Automatic Discovery*: Annotation scanning with configurable package inclusion/exclusion\n* *Spring Boot Integration*: Seamless integration with MCP Boot Starters\n\n== Upgrading to Spring AI 2.0\n\nStarting with **Spring AI 2.0**, the Spring-specific MCP transport implementations (`mcp-spring-webflux` and `mcp-spring-webmvc`) are no longer shipped by the MCP Java SDK. They have been moved into the Spring AI project itself. This is a breaking change that requires dependency and import updates for applications that directly reference these transport artifacts or classes.\n\n=== Maven Dependency Group ID Change\n\nThe `mcp-spring-webflux` and `mcp-spring-webmvc` artifacts have moved from the `io.modelcontextprotocol.sdk` group to `org.springframework.ai`.\n\n.Before (MCP Java SDK < 1.0.x and Spring AI < 2.0.x)\n[source,xml]\n----\n<dependency>\n    <groupId>io.modelcontextprotocol.sdk</groupId>\n    <artifactId>mcp-spring-webflux</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>io.modelcontextprotocol.sdk</groupId>\n    <artifactId>mcp-spring-webmvc</artifactId>\n</dependency>\n----\n\n.After (MCP Java SDK >= 1.0.x and Spring AI >= 2.0.x)\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>mcp-spring-webflux</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>mcp-spring-webmvc</artifactId>\n</dependency>\n----\n\nNOTE: When using the `spring-ai-bom` or the Spring AI starter dependencies (`spring-ai-starter-mcp-server-webflux`, `spring-ai-starter-mcp-server-webmvc`, `spring-ai-starter-mcp-client-webflux`) **no explicit version is needed** — the BOM manages it automatically.\n\n=== Java Package Relocation\n\nAll transport classes have been relocated to `org.springframework.ai` packages.\n\n.Server transport classes\n|===\n|Class |Old package (MCP SDK) |New package (Spring AI)\n\n|`WebFluxSseServerTransportProvider`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webflux.transport`\n\n|`WebFluxStreamableServerTransportProvider`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webflux.transport`\n\n|`WebFluxStatelessServerTransport`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webflux.transport`\n\n|`WebMvcSseServerTransportProvider`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webmvc.transport`\n\n|`WebMvcStreamableServerTransportProvider`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webmvc.transport`\n\n|`WebMvcStatelessServerTransport`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webmvc.transport`\n|===\n\n.Client transport classes\n|===\n|Class |Old package (MCP SDK) |New package (Spring AI)\n\n|`WebFluxSseClientTransport`\n|`io.modelcontextprotocol.client.transport`\n|`org.springframework.ai.mcp.client.webflux.transport`\n\n|`WebClientStreamableHttpTransport`\n|`io.modelcontextprotocol.client.transport`\n|`org.springframework.ai.mcp.client.webflux.transport`\n|===\n\n.Example import update\n[source,java]\n----\n// Before\nimport io.modelcontextprotocol.server.transport.WebFluxSseServerTransportProvider;\nimport io.modelcontextprotocol.server.transport.WebMvcSseServerTransportProvider;\nimport io.modelcontextprotocol.client.transport.WebFluxSseClientTransport;\nimport io.modelcontextprotocol.client.transport.WebClientStreamableHttpTransport;\n\n// After\nimport org.springframework.ai.mcp.server.webflux.transport.WebFluxSseServerTransportProvider;\nimport org.springframework.ai.mcp.server.webmvc.transport.WebMvcSseServerTransportProvider;\nimport org.springframework.ai.mcp.client.webflux.transport.WebFluxSseClientTransport;\nimport org.springframework.ai.mcp.client.webflux.transport.WebClientStreamableHttpTransport;\n----\n\n=== MCP SDK Version Requirement\n\nSpring AI 2.0 requires **MCP Java SDK 1.0.0** (RC1 or later). The SDK version has been bumped from `0.18.x` to the `1.0.x` release line. Update your BOM or explicit version accordingly.\n\n=== Spring Boot Auto-configuration Users\n\nIf you rely **exclusively on Spring Boot auto-configuration** via the Spring AI starters, you do **not** need to change any Java code. The auto-configurations have already been updated internally to reference the new packages. Only update your `pom.xml`/`build.gradle` dependency coordinates as described above.\n\n== Additional Resources\n\n* xref:api/mcp/mcp-annotations-overview.adoc[MCP Annotations Documentation]\n* link:mcp-client-boot-starter-docs.html[MCP Client Boot Starters Documentation]\n* link:mcp-server-boot-starter-docs.html[MCP Server Boot Starters Documentation]\n* link:mcp-helpers.html[MCP Utilities Documentation]\n* link:https://modelcontextprotocol.github.io/specification/[Model Context Protocol Specification]\n"

    "content": "= MCP Security\n\nNOTE: This is still work in progress. The documentation and APIs may change in future releases.\n\nThe Spring AI MCP Security module provides comprehensive OAuth 2.0 and API key-based security support for Model Context Protocol implementations in Spring AI. This community-driven project enables developers to secure both MCP servers and clients with industry-standard authentication and authorization mechanisms.\n\nNOTE: This module is part of the link:https://github.com/spring-ai-community/mcp-security[spring-ai-community/mcp-security] project and currently works with Spring AI's 1.1.x branch only.\nThis is a community-driven project and is not officially endorsed yet by Spring AI or the MCP project.\n\n== Overview\n\nThe MCP Security module provides three main components:\n\n* *MCP Server Security* - OAuth 2.0 resource server and API key authentication for Spring AI MCP servers\n* *MCP Client Security* - OAuth 2.0 client support for Spring AI MCP clients\n* *MCP Authorization Server* - Enhanced Spring Authorization Server with MCP-specific features\n\nThe project enables developers to:\n\n* Secure MCP servers with OAuth 2.0 authentication and API key-based access\n* Configure MCP clients with OAuth 2.0 authorization flows\n* Set up authorization servers specifically designed for MCP workflows\n* Implement fine-grained access control for MCP tools and resources\n\n== MCP Server Security\n\nThe MCP Server Security module provides OAuth 2.0 resource server capabilities for xref:api/mcp/mcp-server-boot-starter-docs.adoc[Spring AI's MCP servers]. \nIt also provides basic support for API-key based authentication. \n\nIMPORTANT: This module is compatible with Spring WebMVC-based servers only.\n\n=== Dependencies\n\nAdd the following dependencies to your project:\n\n[tabs]\n======\nMaven::\n+\n[source,xml]\n----\n<dependencies>\n    <dependency>\n        <groupId>org.springaicommunity</groupId>\n        <artifactId>mcp-server-security</artifactId>\n    </dependency>\n    <dependency>\n        <groupId>org.springframework.boot</groupId>\n        <artifactId>spring-boot-starter-security</artifactId>\n    </dependency>\n\n    <!-- OPTIONAL: For OAuth2 support -->\n    <dependency>\n        <groupId>org.springframework.boot</groupId>\n        <artifactId>spring-boot-starter-oauth2-resource-server</artifactId>\n    </dependency>\n</dependencies>\n----\n\nGradle::\n+\n[source,groovy]\n----\nimplementation 'org.springaicommunity:mcp-server-security'\nimplementation 'org.springframework.boot:spring-boot-starter-security'\n\n// OPTIONAL: For OAuth2 support\nimplementation 'org.springframework.boot:spring-boot-starter-oauth2-resource-server'\n----\n======\n\n=== OAuth 2.0 Configuration\n\n==== Basic OAuth 2.0 Setup\n\nFirst, enable the MCP server in your `application.properties`:\n\n[source,properties]\n----\nspring.ai.mcp.server.name=my-cool-mcp-server\n# Supported protocols: STREAMABLE, STATELESS\nspring.ai.mcp.server.protocol=STREAMABLE\n----\n\nThen, configure security using Spring Security's standard APIs with the provided MCP configurer:\n\n[source,java]\n----\n@Configuration\n@EnableWebSecurity\nclass McpServerConfiguration {\n\n    @Value(\"${spring.security.oauth2.resourceserver.jwt.issuer-uri}\")\n    private String issuerUrl;\n\n    @Bean\n    SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {\n        return http\n                // Enforce authentication with token on EVERY request\n                .authorizeHttpRequests(auth -> auth.anyRequest().authenticated())\n                // Configure OAuth2 on the MCP server\n                .with(\n                        McpServerOAuth2Configurer.mcpServerOAuth2(),\n                        (mcpAuthorization) -> {\n                            // REQUIRED: the issuerURI\n                            mcpAuthorization.authorizationServer(issuerUrl);\n                            // OPTIONAL: enforce the `aud` claim in the JWT token.\n                            // Not all authorization servers support resource indicators,\n                            // so it may be absent.

So I'm just going to say Hello!\".formatted(language);\n        };\n    }\n}\n----\n\nYou can also access the current authentication directly from the tool method using `SecurityContextHolder`:\n\n[source,java]\n----\n@McpTool(name = \"greeter\", description = \"A tool that greets the user by name, in the selected language\")\n@PreAuthorize(\"isAuthenticated()\")\npublic String greet(\n        @ToolParam(description = \"The language for the greeting (example: english, french, ...)\") String language\n) {\n    if (!StringUtils.hasText(language)) {\n        language = \"\";\n    }\n    var authentication = SecurityContextHolder.getContext().getAuthentication();\n    var name = authentication.getName();\n    return switch (language.toLowerCase()) {\n        case \"english\" -> \"Hello, %s!\".formatted(name);\n        case \"french\" -> \"Salut %s!\".formatted(name);\n        default -> (\"I don't understand language \\\"%s\\\". \" +\n                    \"So I'm just going to say Hello %s!\").formatted(language, name);\n    };\n}\n----\n\n=== API Key Authentication\n\nThe MCP Server Security module also supports API key-based authentication. You need to provide your own implementation of `ApiKeyEntityRepository` for storing `ApiKeyEntity` objects.\n\nA sample implementation is available with `InMemoryApiKeyEntityRepository` along with a default `ApiKeyEntityImpl`:\n\nWARNING: The `InMemoryApiKeyEntityRepository` uses bcrypt for storing API keys, which is computationally expensive.

Use JWT.\n\n====\n\n== MCP Client Security\n\nThe MCP Client Security module provides OAuth 2.0 support for xref:api/mcp/mcp-client-boot-starter-docs.adoc[Spring AI's MCP clients], supporting both HttpClient-based clients (from `spring-ai-starter-mcp-client`) and WebClient-based clients (from `spring-ai-starter-mcp-client-webflux`). \n\nIMPORTANT: This module supports `McpSyncClient` only.\n\n=== Dependencies\n\n[tabs]\n======\nMaven::\n+\n[source,xml]\n----\n<dependency>\n    <groupId>org.springaicommunity</groupId>\n    <artifactId>mcp-client-security</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\nimplementation 'org.springaicommunity:mcp-client-security'\n----\n======\n\n=== Authorization Flows\n\nThree OAuth 2.0 flows are available for obtaining tokens:\n\n* *Authorization Code Flow* - For user-level permissions when every MCP request is made within the context of a user request\n* *Client Credentials Flow* - For machine-to-machine use cases where no human is in the loop\n* *Hybrid Flow* - Combines both flows for scenarios where some operations (like `initialize` or `tools/list`) happen without a user present, but tool calls require user-level permissions\n\nTIP: Use authorization code flow when you have user-level permissions and all MCP requests occur within user context. Use client credentials for machine-to-machine communication. Use hybrid flow when using Spring Boot properties for MCP client configuration, as tool discovery happens at startup without a user present.\n\n=== Common Setup\n\nFor all flows, activate Spring Security's OAuth2 client support in your `application.properties`:\n\n[source,properties]\n----\n# Ensure MCP clients are sync\nspring.ai.mcp.client.type=SYNC\n\n# For authorization_code or hybrid flow\nspring.security.oauth2.client.registration.authserver.client-id=<THE CLIENT ID>\nspring.security.oauth2.client.registration.authserver.client-secret=<THE CLIENT SECRET>\nspring.security.oauth2.client.registration.authserver.authorization-grant-type=authorization_code\nspring.security.oauth2.client.registration.authserver.provider=authserver\n\n# For client_credentials or hybrid flow\nspring.security.oauth2.client.registration.authserver-client-credentials.client-id=<THE CLIENT ID>\nspring.security.oauth2.client.registration.authserver-client-credentials.client-secret=<THE CLIENT SECRET>\nspring.security.oauth2.client.registration.authserver-client-credentials.authorization-grant-type=client_credentials\nspring.security.oauth2.client.registration.authserver-client-credentials.provider=authserver\n\n# Authorization server configuration\nspring.security.oauth2.client.provider.authserver.issuer-uri=<THE ISSUER URI OF YOUR AUTH SERVER>\n----\n\nThen, create a configuration class activating OAuth2 client capabilities:\n\n[source,java]\n----\n@Configuration\n@EnableWebSecurity\nclass SecurityConfiguration {\n\n    @Bean\n    SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {\n        return http\n                // in this example, the client app has no security on its endpoints\n                .authorizeHttpRequests(auth -> auth.anyRequest().permitAll())\n                // turn on OAuth2 support\n                .oauth2Client(Customizer.withDefaults())\n                .build();\n    }\n}\n----\n\n=== HttpClient-Based Clients\n\nWhen using `spring-ai-starter-mcp-client`, configure a `McpSyncHttpClientRequestCustomizer` bean:\n\n[source,java]\n----\n@Configuration\nclass McpConfiguration {\n\n    @Bean\n    McpCustomizer<McpClient.SyncSpec> syncClientCustomizer() {\n        return (name, syncSpec) ->\n                syncSpec.transportContextProvider(\n                        new AuthenticationMcpTransportContextProvider()\n                );\n    }\n\n    @Bean\n    McpSyncHttpClientRequestCustomizer requestCustomizer(\n            OAuth2AuthorizedClientManager clientManager\n    ) {\n        // The clientRegistration name, \"authserver\",\n        // must match the name in application.properties\n        return new OAuth2AuthorizationCodeSyncHttpRequestCustomizer(\n                clientManager,\n                \"authserver\"\n        );\n    }\n}\n----\n\nAvailable customizers:\n\n* `OAuth2AuthorizationCodeSyncHttpRequestCustomizer` - For authorization code flow\n* `OAuth2ClientCredentialsSyncHttpRequestCustomizer` - For client credentials flow\n* `OAuth2HybridSyncHttpRequestCustomizer` - For hybrid flow\n\n=== WebClient-Based Clients\n\nWhen using `spring-ai-starter-mcp-client-webflux`, configure a `WebClient.Builder` with an MCP `ExchangeFilterFunction`:\n\n[source,java]\n----\n@Configuration\nclass McpConfiguration {\n\n    @Bean\n    McpCustomizer<McpClient.SyncSpec> syncClientCustomizer() {\n        return (name, syncSpec) ->\n                syncSpec.transportContextProvider(\n                        new AuthenticationMcpTransportContextProvider()\n                );\n    }\n\n    @Bean\n    WebClient.Builder mcpWebClientBuilder(OAuth2AuthorizedClientManager clientManager) {\n        // The clientRegistration name, \"authserver\", must match the name in application.properties\n        return WebClient.builder().filter(\n                new McpOAuth2AuthorizationCodeExchangeFilterFunction(\n                        clientManager,\n                        \"authserver\"\n                )\n        );\n    }\n}\n----\n\nAvailable filter functions:\n\n* `McpOAuth2AuthorizationCodeExchangeFilterFunction` - For authorization code flow\n* `McpOAuth2ClientCredentialsExchangeFilterFunction` - For client credentials flow\n* `McpOAuth2HybridExchangeFilterFunction` - For hybrid flow\n\n=== Working Around Spring AI Autoconfiguration\n\nSpring AI's autoconfiguration initializes MCP clients at startup, which can cause issues with user-based authentication. To avoid this:\n\n==== Option 1: Disable @Tool Auto-configuration\n\nDisable Spring AI's `@Tool` autoconfiguration by publishing an empty `ToolCallbackResolver` bean:\n\n[source,java]\n----\n@Configuration\npublic class McpConfiguration {\n\n    @Bean\n    ToolCallbackResolver resolver() {\n        return new StaticToolCallbackResolver(List.of());\n    }\n}\n----\n\n==== Option 2: Programmatic Client Configuration\n\nConfigure MCP clients programmatically instead of using Spring Boot properties. For HttpClient-based clients:\n\n[source,java]\n----\n@Bean\nMcpSyncClient client(\n        JsonMapper jsonMapper,\n        McpSyncHttpClientRequestCustomizer requestCustomizer,\n        McpClientCommonProperties commonProps\n) {\n    var transport = HttpClientStreamableHttpTransport.builder(mcpServerUrl)\n            .clientBuilder(HttpClient.newBuilder())\n            .jsonMapper(new JacksonMcpJsonMapper(jsonMapper))\n            .httpRequestCustomizer(requestCustomizer)\n            .build();\n\n    var clientInfo = new McpSchema.Implementation(\"client-name\", commonProps.getVersion());\n\n    return McpClient.sync(transport)\n            .clientInfo(clientInfo)\n            .requestTimeout(commonProps.getRequestTimeout())\n            .transportContextProvider(new AuthenticationMcpTransportContextProvider())\n            .build();\n}\n----\n\nFor WebClient-based clients:\n\n[source,java]\n----\n@Bean\nMcpSyncClient client(\n        WebClient.Builder mcpWebClientBuilder,\n        JsonMapper jsonMapper,\n        McpClientCommonProperties commonProperties\n) {\n    var builder = mcpWebClientBuilder.baseUrl(mcpServerUrl);\n    var transport = WebClientStreamableHttpTransport.builder(builder)\n            .jsonMapper(new JacksonMcpJsonMapper(jsonMapper))\n            .build();\n\n    var clientInfo = new McpSchema.Implementation(\"clientName\", commonProperties.getVersion());\n\n    return McpClient.sync(transport)\n            .clientInfo(clientInfo)\n            .requestTimeout(commonProperties.getRequestTimeout())\n            .transportContextProvider(new AuthenticationMcpTransportContextProvider())\n            .build();\n}\n----\n\nThen add the client to your chat client:\n\n[source,java]\n----\nvar chatResponse = chatClient.prompt(\"Prompt the LLM to do the thing\")\n        .toolCallbacks(new SyncMcpToolCallbackProvider(mcpClient1, mcpClient2, mcpClient3))\n        .call()\n        .content();\n----\n\n=== Known Limitations\n\n[IMPORTANT]\n====\n\n* Spring WebFlux servers are not supported.\n* Spring AI autoconfiguration initializes MCP clients at app start, requiring workarounds for user-based authentication.\n* Unlike the server module, the client implementation supports the SSE transport with both `HttpClient` and `WebClient`.\n\n====\n\n== MCP Authorization Server\n\nThe MCP Authorization Server module enhances link:https://docs.spring.io/spring-security/reference/7.0/servlet/oauth2/authorization-server/index.html[Spring Security's OAuth 2.0 Authorization Server] with features relevant to the link:https://modelcontextprotocol.io/specification/2025-06-18/basic/authorization[MCP authorization spec], such as Dynamic Client Registration and Resource Indicators.\n\n=== Dependencies\n\n[tabs]\n======\nMaven::\n+\n[source,xml]\n----\n<dependency>\n    <groupId>org.springaicommunity</groupId>\n    <artifactId>mcp-authorization-server</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy]\n----\nimplementation 'org.springaicommunity:mcp-authorization-server'\n----\n======\n\n=== Configuration\n\nConfigure the authorization server in your `application.yml`:\n\n[source,yaml]\n----\nspring:\n  application:\n    name: sample-authorization-server\n  security:\n    oauth2:\n      authorizationserver:\n        client:\n          default-client:\n            token:\n              access-token-time-to-live: 1h\n            registration:\n              client-id: \"default-client\"\n              client-secret: \"{noop}default-secret\"\n              client-authentication-methods:\n                -

Disabling a capability will prevent the server from registering and exposing the corresponding features to clients.\n\n== Server Protocols\n\nMCP provides several protocol types including:\n\n* xref:api/mcp/mcp-stdio-sse-server-boot-starter-docs.adoc[**STDIO**] - In process (e.g. server runs inside the host application) protocol. Communication is over standard in and standard out. To enable the `STDIO` set `spring.ai.mcp.server.stdio=true`.\n* xref:api/mcp/mcp-stdio-sse-server-boot-starter-docs.adoc#_sse_webmvc_server[**SSE**] - Server-sent events protocol for real-time updates. The server operates as an independent process that can handle multiple client connections.\n* xref:api/mcp/mcp-streamable-http-server-boot-starter-docs.adoc[**Streamable-HTTP**] - The link:https://modelcontextprotocol.io/specification/2025-06-18/basic/transports#streamable-http[Streamable HTTP transport] allows MCP servers to operate as independent processes that can handle multiple client connections using HTTP POST and GET requests, with optional Server-Sent Events (SSE) streaming for multiple server messages. It replaces the SSE transport. To enable the `STREAMABLE` protocol, set `spring.ai.mcp.server.protocol=STREAMABLE`.\n* xref:api/mcp/mcp-stateless-server-boot-starter-docs.adoc[**Stateless**] - Stateless MCP servers are designed for simplified deployments where session state is not maintained between requests.\nThey are ideal for microservices architectures and cloud-native deployments. To enable the `STATELESS` protocol, set `spring.ai.mcp.server.protocol=STATELESS`.\n\n== Sync/Async Server API Options\n\nThe MCP Server API supports imperative (i.e. synchronous) and reactive (e.g. asynchronous) programming models.\n\n* **Synchronous Server** - The default server type implemented using `McpSyncServer`.\nIt is designed for straightforward request-response patterns in your applications.\nTo enable this server type, set `spring.ai.mcp.server.type=SYNC` in your configuration.\nWhen activated, it automatically handles the configuration of synchronous tool specifications.\n\n**NOTE:** The SYNC server will register only synchronous MCP annotated methods. Asynchronous methods will be ignored.\n\n* **Asynchronous Server** - The asynchronous server implementation uses `McpAsyncServer` and is optimized for non-blocking operations.\nTo enable this server type, configure your application with `spring.ai.mcp.server.type=ASYNC`.\nThis server type automatically sets up asynchronous tool specifications with built-in Project Reactor support.\n\n**NOTE:** The ASYNC server will register only asynchronous MCP annotated methods. Synchronous methods will be ignored.\n\n\n\n== MCP Server Annotations\n\nThe MCP Server Boot Starters provide comprehensive support for annotation-based server development, allowing you to create MCP servers using declarative Java annotations instead of manual configuration.\n\n=== Key Annotations\n\n* **xref:api/mcp/mcp-annotations-server.adoc#_mcptool[@McpTool]** - Mark methods as MCP tools with automatic JSON schema generation\n* **xref:api/mcp/mcp-annotations-server.adoc#_mcpresource[@McpResource]** - Provide access to resources via URI templates\n* **xref:api/mcp/mcp-annotations-server.adoc#_mcpprompt[@McpPrompt]** - Generate prompt messages for AI interactions\n* **xref:api/mcp/mcp-annotations-server.adoc#_mcpcomplete[@McpComplete]** - Provide auto-completion functionality for prompts\n\n=== Special Parameters\n\nThe annotation system supports xref:api/mcp/mcp-annotations-special-params.adoc[special parameter types] that provide additional context:\n\n* **`McpMeta`** - Access metadata from MCP requests\n* **`@McpProgressToken`** - Receive progress tokens for long-running operations\n* **`McpSyncServerExchange`/`McpAsyncServerExchange`** - Full server context for advanced operations\n* **`McpTransportContext`** - Lightweight context for stateless operations\n* **`CallToolRequest`** - Dynamic schema support for flexible tools\n\n=== Simple Example\n\n[source,java]\n----\n@Component\npublic class CalculatorTools {\n\n    @McpTool(name = \"add\", description = \"Add two numbers together\")\n    public int add(\n            @McpToolParam(description = \"First number\", required = true) int a,\n            @McpToolParam(description = \"Second number\", required = true) int b) {\n        return a + b;\n    }\n\n    @McpResource(uri = \"config://{key}\", name = \"Configuration\")\n    public String getConfig(String key) {\n        return configData.get(key);\n    }\n}\n----\n\n=== Adding data to McpTransportContext\n\nBy default, the `McpTransportContext` is empty (`McpTransportContext.EMPTY`).\nThis is by design, to keep the MCP server transport-agnostic.\n\nIf you need transport-specific metadata (for example, HTTP headers, remote host, etc) in your tools,\nconfigure a `TransportContextExtractor` on your transport provider.\n\n[source,java]\n----\n@Bean\npublic WebMvcStreamableServerTransportProvider transport(ObjectMapper objectMapper) {\n    return WebMvcStreamableServerTransportProvider.builder()\n        .contextExtractor(serverRequest -> {\n            String authorization = serverRequest.headers().firstHeader(\"Authorization\");\n            return McpTransportContext.create(Map.of(\"authorization\", authorization));\n        })\n        .build();\n}\n----\n\nOnce configured, access the context via `McpSyncRequestContext` (or `McpAsyncRequestContext`) in your tool.\n\n[source,java]\n----\n@McpTool\npublic String accessProtectedResource(McpSyncRequestContext requestContext) {\n    McpTransportContext context = requestContext.transportContext();\n    String authorization = (String) context.get(\"authorization\");\n\n    return \"Successfully accessed protected resource.\";\n}\n----\n\n=== Auto-Configuration\n\nWith Spring Boot auto-configuration, annotated beans are automatically detected and registered:\n\n[source,java]\n----\n@SpringBootApplication\npublic class McpServerApplication {\n    public static void main(String[] args) {\n        SpringApplication.run(McpServerApplication.class, args);\n    }\n}\n----\n\nThe auto-configuration will:\n\n1. Scan for beans with MCP annotations\n2. Create appropriate specifications\n3. Register them with the MCP server\n4. Handle both sync and async implementations based on configuration\n\n=== Configuration Properties\n\nConfigure the server annotation scanner:\n\n[source,yaml]\n----\nspring:\n  ai:\n    mcp:\n      server:\n        type: SYNC  # or ASYNC\n        annotation-scanner:\n          enabled: true\n----\n\n=== Additional Resources\n\n* xref:api/mcp/mcp-annotations-server.adoc[Server Annotations Reference] - Complete guide to server annotations\n* xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters] - Advanced parameter injection\n* xref:api/mcp/mcp-annotations-examples.adoc[Examples] - Comprehensive examples and use cases\n\n\n== Example Applications\n\n* link:https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol/weather/starter-webflux-server[Weather Server (SSE WebFlux)] - Spring AI MCP Server Boot Starter with WebFlux transport\n* link:https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol/weather/starter-stdio-server[Weather Server (STDIO)] - Spring AI MCP Server Boot Starter with STDIO transport\n* link:https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol/weather/manual-webflux-server[Weather Server Manual Configuration] - Spring AI MCP Server Boot Starter that doesn't use auto-configuration but uses the Java SDK to configure the server manually\n* Streamable-HTTP WebFlux/WebMVC Example - TODO\n* Stateless WebFlux/WebMVC Example - TODO\n\n== Additional Resources\n\n* xref:api/mcp/mcp-annotations-server.adoc[MCP Server Annotations] - Declarative server development with annotations\n* xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters] - Advanced parameter injection and context access\n* xref:api/mcp/mcp-annotations-examples.adoc[MCP Annotations Examples] - Comprehensive examples and use cases\n* link:https://docs.spring.io/spring-ai/reference/[Spring AI Documentation]\n* link:https://modelcontextprotocol.io/specification[Model Context Protocol Specification]\n* link:https://docs.spring.io/spring-boot/docs/current/reference/html/features.html#features.developing-auto-configuration[Spring Boot Auto-configuration]\n"

It replaces the SSE transport.\n\nThese servers, introduced with spec version link:https://modelcontextprotocol.io/specification/2025-03-26[2025-03-26], are ideal for applications that need to notify clients about dynamic changes to tools, resources, or prompts.\n\nTIP: Set the `spring.ai.mcp.server.protocol=STREAMABLE` property\n\nTIP: Use the xref:api/mcp/mcp-client-boot-starter-docs#_streamable_http_transport_properties[Streamable-HTTP clients] to connect to the Streamable-HTTP servers.\n\n=== Streamable-HTTP WebMVC Server\n\nUse the `spring-ai-starter-mcp-server-webmvc` dependency:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-mcp-server-webmvc</artifactId>\n</dependency>\n----\n\nand set the `spring.ai.mcp.server.protocol` property to `STREAMABLE`.\n\n* Full MCP server capabilities with Spring MVC Streamable transport\n* Support for tools, resources, prompts, completion, logging, progression, ping, root-changes capabilities\n* Persistent connection management\n\n=== Streamable-HTTP WebFlux Server\n\nUse the `spring-ai-starter-mcp-server-webflux` dependency:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-mcp-server-webflux</artifactId>\n</dependency>\n----\n\nand set the `spring.ai.mcp.server.protocol` property to `STREAMABLE`.\n\n* Reactive MCP server with WebFlux Streamable transport\n* Support for tools, resources, prompts, completion, logging, progression, ping, root-changes capabilities\n* Non-blocking, persistent connection management\n\n== Configuration Properties\n\n=== Common Properties\n\nAll common properties are prefixed with `spring.ai.mcp.server`:\n\n[options=\"header\"]\n|===\n|Property |Description |Default\n|`enabled` |Enable/disable the streamable MCP server |`true`\n|`protocol` |MCP server protocol | Must be set to `STREAMABLE` to enable the streamable server\n|`tool-callback-converter` |Enable/disable the conversion of Spring AI ToolCallbacks into MCP Tool specs |`true`\n|`name` |Server name for identification |`mcp-server`\n|`version` |Server version |`1.0.0`\n|`instructions` |Optional instructions for client interaction |`null`\n|`type` |Server type (SYNC/ASYNC) |`SYNC`\n|`capabilities.resource` |Enable/disable resource capabilities |`true`\n|`capabilities.tool` |Enable/disable tool capabilities |`true`\n|`capabilities.prompt` |Enable/disable prompt capabilities |`true`\n|`capabilities.completion` |Enable/disable completion capabilities |`true`\n|`resource-change-notification` |Enable resource change notifications |`true`\n|`prompt-change-notification` |Enable prompt change notifications |`true`\n|`tool-change-notification` |Enable tool change notifications |`true`\n|`expose-mcp-client-tools` |Whether to re-expose downstream MCP tools (provided by MCP clients) as tools in this MCP server |`false`\n|`tool-response-mime-type` |Response MIME type per tool name |`-`\n|`request-timeout` |Request timeout duration |`20 seconds`\n|===\n\n=== MCP Annotations Properties\n\nMCP Server Annotations provide a declarative way to implement MCP server handlers using Java annotations.\n\nThe server mcp-annotations properties are prefixed with `spring.ai.mcp.server.annotation-scanner`:\n\n[cols=\"3,4,3\"]\n|===\n|Property |Description |Default Value\n\n|`enabled`\n|Enable/disable the MCP server annotations auto-scanning\n|`true`\n\n|===\n\n=== Streamable-HTTP Properties\n\nAll streamable-HTTP properties are prefixed with `spring.ai.mcp.server.streamable-http`:\n\n[options=\"header\"]\n|===\n|Property |Description |Default\n|`mcp-endpoint` |Custom MCP endpoint path |`/mcp`\n|`keep-alive-interval` |Connection keep-alive interval |`null` (disabled)\n|`disallow-delete` |Disallow delete operations |`false`\n|===\n\n== Features and Capabilities\n\nThe MCP Server supports four main capability types that can be individually enabled or disabled:\n\n- **Tools** - Enable/disable tool capabilities with `spring.ai.mcp.server.capabilities.tool=true|false`\n- **Resources** - Enable/disable resource capabilities with `spring.ai.mcp.server.capabilities.resource=true|false`\n- **Prompts** - Enable/disable prompt capabilities with `spring.ai.mcp.server.capabilities.prompt=true|false`\n- **Completions** - Enable/disable completion capabilities with `spring.ai.mcp.server.capabilities.completion=true|false`\n\nAll capabilities are enabled by default. Disabling a capability will prevent the server from registering and exposing the corresponding features to clients.\n\nThe MCP Server Boot Starter allows servers to expose tools, resources, and prompts to clients.\nIt automatically converts custom capability handlers registered as Spring beans to sync/async specifications based on the server type:\n\n=== link:https://modelcontextprotocol.io/specification/2025-03-26/server/tools[Tools]\nAllows servers to expose tools that can be invoked by language models.

    "content": "= Moderation\n\n== Introduction\n\nSpring AI supports the new moderation service introduced by Mistral AI and powered by the Mistral Moderation model.\nIt enables the detection of harmful text content along several policy dimensions.\nFollow this https://docs.mistral.ai/capabilities/guardrailing/[link] for more information on the Mistral AI moderation model.\n\n== Prerequisites\n\n. Create an Mistral AI account and obtain an API key. You can sign up at https://auth.mistral.ai/ui/registration[Mistral AI registration page] and generate an API key on the https://console.mistral.ai/api-keys/[API Keys page].\n. Add the `spring-ai-mistral-ai` dependency to your project's build file. For more information, refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section.\n\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the Mistral AI Moderation Model.\nTo enable it add the following dependency to your project's Maven `pom.xml` file:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-mistral-ai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file:\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-mistral-ai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n== Moderation Properties\n\n=== Connection Properties\nThe prefix spring.ai.mistralai is used as the property prefix that lets you connect to Mistral AI.\n[cols=\"3,3,1\"]\n|====\n| Property | Description | Default\n| spring.ai.mistralai.base-url   | The URL to connect to |  https://api.mistral.ai\n| spring.ai.mistralai.api-key    | The API Key           |  -\n|====\n\n=== Configuration Properties\n\n[NOTE]\n====\nEnabling and disabling of the moderation auto-configurations are now configured via top level properties with the prefix `spring.ai.model.moderation`.\n\nTo enable, spring.ai.model.moderation=mistral (It is enabled by default)\n\nTo disable, spring.ai.model.moderation=none (or any value which doesn't match mistral)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix spring.ai.mistralai.moderation is used as the property prefix for configuring the Mistral AI moderation model.\n[cols=\"3,5,1\"]\n|====\n| Property | Description | Default\n| spring.ai.model.moderation   | Enable Moderation model |  mistral\n| spring.ai.mistralai.moderation.base-url   | The URL to connect to |  https://api.mistral.ai\n| spring.ai.mistralai.moderation.api-key    | The API Key           |  -\n| spring.ai.mistralai.moderation.options.model  | ID of the model to use for moderation. | mistral-moderation-latest\n|====\n\nNOTE: You can override the common `spring.ai.mistralai.base-url`, `spring.ai.mistralai.api-key`, properties.\nThe `spring.ai.mistralai.moderation.base-url`, `spring.ai.mistralai.moderation.api-key`, properties, if set, take precedence over the common properties.\nThis is useful if you want to use different Mistral AI accounts for different models and different model endpoints.\n\nTIP: All properties prefixed with `spring.ai.mistralai.moderation.options` can be overridden at runtime.\n\n== Runtime Options\nThe MistralAiModerationOptions class provides the options to use when making a moderation request.\nOn start-up, the options specified by spring.ai.mistralai.moderation are used, but you can override these at runtime.\n\nFor example:\n\n[source,java]\n----\nMistralAiModerationOptions moderationOptions = MistralAiModerationOptions.builder()\n    .model(\"mistral-moderation-latest\")\n    .build();\n\nModerationPrompt moderationPrompt = new ModerationPrompt(\"Text to be moderated\",

    "content": "= Moderation\n\n== Introduction\n\nSpring AI supports OpenAI's Moderation model, which allows you to detect potentially harmful or sensitive content in text.\nFollow this https://platform.openai.com/docs/guides/moderation[guide] to for more information on OpenAI's moderation model.\n\n[NOTE]\n====\nStarting from version `2.0.0-M5`, Spring AI uses the official `openai-java` SDK under the hood for all OpenAI models. The transition is expected to be seamless and there are no breaking changes for existing users of the OpenAI API properties and builders. If you find any issues, please report them to us at https://github.com/spring-projects/spring-ai/issues[Spring AI GitHub Issues].\n====\n\n== Prerequisites\n\n. Create an OpenAI account and obtain an API key. You can sign up at the https://platform.openai.com/signup[OpenAI signup page] and generate an API key on the https://platform.openai.com/account/api-keys[API Keys page].\n. Add the `spring-ai-openai` dependency to your project's build file. For more information, refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section.\n\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the OpenAI Moderation Model.\nTo enable it add the following dependency to your project's Maven `pom.xml` file:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-openai</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file:\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-model-openai'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n== Moderation Properties\n\n=== Connection Properties\nThe prefix spring.ai.openai is used as the property prefix that lets you connect to OpenAI.\n[cols=\"3,5,1\"]\n|====\n| Property | Description | Default\n| spring.ai.openai.base-url   | The URL to connect to |  https://api.openai.com\n| spring.ai.openai.api-key    | The API Key           |  -\n| spring.ai.openai.organization-id | Optionally you can specify which organization is used for an API request. |  -\n| spring.ai.openai.project-id      | Optionally, you can specify which project is used for an API request. |  -\n|====\n\nTIP: For users that belong to multiple organizations (or are accessing their projects through their legacy user API key), optionally, you can specify which organization and project is used for an API request.\nUsage from these API requests will count as usage for the specified organization and project.\n\n=== Configuration Properties\n\n[NOTE]\n====\nEnabling and disabling of the embedding auto-configurations are now configured via top level properties with the prefix `spring.ai.model.moderation`.\n\nTo enable, spring.ai.model.moderation=openai (It is enabled by default)\n\nTo disable, spring.ai.model.moderation=none (or any value which doesn't match openai)\n\nThis change is done to allow configuration of multiple models.\n====\n\nThe prefix spring.ai.openai.moderation is used as the property prefix for configuring the OpenAI moderation model.\n[cols=\"3,5,2\"]\n|====\n| Property | Description | Default\n| spring.ai.model.moderation   | Enable Moderation model |  openai\n| spring.ai.openai.moderation.base-url   | The URL to connect to |  https://api.openai.com\n| spring.ai.openai.moderation.api-key    | The API Key           |  -\n| spring.ai.openai.moderation.organization-id | Optionally you can specify which organization is used for an API request. |  -\n| spring.ai.openai.moderation.project-id      | Optionally, you can specify which project is used for an API request. |  -\n| spring.ai.openai.moderation.moderation-path | The API endpoint path for moderation requests. Useful for OpenAI-compatible APIs with different endpoint structures. | /v1/moderations\n| spring.ai.openai.moderation.options.model  | ID of the model to use for moderation. | omni-moderation-latest\n|====\n\nNOTE: You can override the common `spring.ai.openai.base-url`, `spring.ai.openai.api-key`, `spring.ai.openai.organization-id` and `spring.ai.openai.project-id` properties.\nThe `spring.ai.openai.moderation.base-url`, `spring.ai.openai.moderation.api-key`, `spring.ai.openai.moderation.organization-id` and `spring.ai.openai.moderation.project-id` properties, if set, take precedence over the common properties.\nThis is useful if you want to use different OpenAI accounts for different models and different model endpoints.\n\nTIP: All properties prefixed with `spring.ai.openai.moderation.options` can be overridden at runtime.\n\n=== Custom API Paths\n\nFor OpenAI-compatible APIs (such as LocalAI, custom proxies, or other OpenAI-compatible services) that use different endpoint paths, you can configure the moderation path:\n\n[source,properties]\n----\nspring.ai.openai.moderation.moderation-path=/custom/path/to/moderations\n----\n\nThis is particularly useful when:\n\n* Using API gateways or proxies that modify standard OpenAI paths\n* Working with OpenAI-compatible services that implement different URL structures\n* Testing against mock endpoints with custom paths\n* Deploying in environments with path-based routing requirements\n\n== Runtime Options\nThe OpenAiModerationOptions class provides the options to use when making a moderation request.\nOn start-up, the options specified by spring.ai.openai.moderation are used, but you can override these at runtime.\n\nFor example:\n\n[source,java]\n----\nOpenAiModerationOptions

It does not hold significance for system messages. The `AssistantMessage`, which includes the LLM response, provides text content only. To generate non-text media outputs, you should utilize one of the dedicated, single-modality models.*\n\nFor example, we can take the following picture (`multimodal.test.png`) as an input and ask the LLM to explain what it sees.\n\nimage::multimodal.test.png[Multimodal Test Image, 200, 200, align=\"left\"]\n\nFor most of the multimodal LLMs, the Spring AI code would look something like this:\n\n[source,java]\n----\nvar imageResource = new ClassPathResource(\"/multimodal.test.png\");\n\nvar userMessage = UserMessage.builder()\n    .text(\"Explain what do you see in this picture?\") // content\n    .media(new Media(MimeTypeUtils.IMAGE_PNG, this.imageResource)) // media\n    .build();\n\nChatResponse response = chatModel.call(new Prompt(this.userMessage));\n----\n\nor with the fluent xref::api/chatclient.adoc[ChatClient] API:\n\n[source,java]\n----\nString response = ChatClient.create(chatModel).prompt()\n\t\t.user(u -> u.text(\"Explain what do you see on this picture?\")\n\t\t\t\t    .media(MimeTypeUtils.IMAGE_PNG, new ClassPathResource(\"/multimodal.test.png\")))\n\t\t.call()\n\t\t.content();\n----\n\nand produce a response like:\n\n> This is an image of a fruit bowl with a simple design.

The bowl has a metal ring at the top, likely to serve as a handle for carrying.

    "content": "[[prompts]]\n= Prompts\n\nPrompts are the inputs that guide an AI model to generate specific outputs.\nThe design and phrasing of these prompts significantly influence the model's responses.\n\nAt the lowest level of interaction with AI models in Spring AI, handling prompts in Spring AI is somewhat similar to managing the \"View\" in Spring MVC.\nThis involves creating extensive text with placeholders for dynamic content.\nThese placeholders are then replaced based on user requests or other code in the application.\nAnother analogy is a SQL statement that contain placeholders for certain expressions.\n\nAs Spring AI evolves, it will introduce higher levels of abstraction for interacting with AI models.\nThe foundational classes described in this section can be likened to JDBC in terms of their role and functionality.\nThe `ChatModel` class, for instance, is analogous to the core JDBC library in the JDK.\nThe `ChatClient` class can be likened to the `JdbcClient`, built on top of `ChatModel` and providing more advanced constructs via `Advisor`\nto consider past interactions with the model, augment the prompt with additional contextual documents, and introduce agentic behavior.\n\nThe structure of prompts has evolved over time within the AI field.\nInitially, prompts were simple strings.\nOver time, they grew to include placeholders for specific inputs, like \"USER:\", which the AI model recognizes.\nOpenAI have introduced even more structure to prompts by categorizing multiple message strings into distinct roles before they are processed by the AI model.\n\n== API Overview\n\n=== Prompt\n\nIt is common to use the `call()` method of `ChatModel` that takes a `Prompt` instance and returns a `ChatResponse`.\n\nThe `Prompt` class functions as a container for an organized series of `Message` objects and a request `ChatOptions`.\nEvery `Message` embodies a unique role within the prompt, differing in its content and intent.\nThese roles can encompass a variety of elements, from user inquiries to AI-generated responses to relevant background information.\nThis arrangement enables intricate and detailed interactions with AI models, as the prompt is constructed from multiple messages, each assigned a specific role to play in the dialogue.\n\nBelow is a truncated version of the Prompt class, with constructors and utility methods omitted for brevity:\n\n[source,java]\n----\npublic class Prompt implements ModelRequest<List<Message>> {\n\n    private final List<Message> messages;\n\n    private ChatOptions chatOptions;\n}\n----\n\n==== Convenience Methods\n\nThe `Prompt` class provides several convenience methods for accessing messages by their role:\n\n**Single Message Access:**\n\n* `getUserMessage()`: Returns the last user message in the prompt, or an empty `UserMessage` if none exists\n* `getSystemMessage()`: Returns the first system message in the prompt, or an empty `SystemMessage` if none exists\n* `getLastUserOrToolResponseMessage()`: Returns the last user or tool response message, useful for conversation continuity\n\n**Multiple Message Access:**\n\n* `getUserMessages()`: Returns a list of all user messages in the prompt, preserving their order\n* `getSystemMessages()`: Returns a list of all system messages in the prompt, preserving their order\n\nThese methods are particularly useful when working with multi-turn conversations or when you need to process messages by role.\n\n=== Message\n\nThe `Message` interface encapsulates a `Prompt` textual content, a collection of metadata attributes, and a categorization known as `MessageType`.\n\nThe interface is defined as follows:\n\n[source,java]\n----\npublic interface Content {\n\n\tString getContent();\n\n\tMap<String, Object> getMetadata();\n}\n\npublic interface Message extends Content {\n\n\tMessageType getMessageType();\n}\n----\n\nThe multimodal message types implement also the `MediaContent` interface providing a list of `Media` content objects.\n\n[source,java]\n----\npublic interface MediaContent extends Content {\n\n\tCollection<Media> getMedia();\n\n}\n----\n\nVarious implementations of the `Message` interface correspond to different categories of messages that an AI model can process. \nThe Models distinguish between message categories based on conversational roles. \n\nimage::spring-ai-message-api.jpg[Spring AI Message API, width=800, align=\"center\"]\n\nThese roles are effectively mapped by the `MessageType`, as discussed below.\n\n==== Roles\n\nEach message is assigned a specific role.\nThese roles categorize the messages, clarifying the context and purpose of each segment of the prompt for the AI model.\nThis structured approach enhances the nuance and effectiveness of communication with the AI, as each part of the prompt plays a distinct and defined role in the interaction.\n\nThe primary roles are:\n\n* System Role: Guides the AI's behavior and response style, setting parameters or rules for how the AI interprets and replies to the input. It's akin to providing instructions to the AI before initiating a conversation.\n* User Role: Represents the user's input – their questions, commands, or statements to the AI. This role is fundamental as it forms the basis of the AI's response.\n* Assistant Role: The AI's response to the user's input. \nMore than just an answer or reaction, it's crucial for maintaining the flow of the conversation. \nBy tracking the AI's previous responses (its 'Assistant Role' messages), the system ensures coherent and contextually relevant interactions.\nThe Assistant message may contain Function Tool Call request information as well.\nIt's like a special feature in the AI, used when needed to perform specific functions such as calculations, fetching data, or other tasks beyond just talking.\n* Tool/Function Role: The Tool/Function Role focuses on returning additional information in response to Tool Call Assistant Messages.\n\nRoles are represented as an enumeration in Spring AI as shown below\n\n[source,java]\n----\npublic enum MessageType {\n\n\tUSER(\"user\"),\n\n\tASSISTANT(\"assistant\"),\n\n\tSYSTEM(\"system\"),\n\n\tTOOL(\"tool\");\n\n    ...\n}\n----\n\n=== PromptTemplate\n\nA key component for prompt templating in Spring AI is the `PromptTemplate` class, designed to facilitate the creation of structured prompts that are then sent to the AI model for processing\n\n[source,java]\n----\npublic class PromptTemplate implements PromptTemplateActions, PromptTemplateMessageActions {\n\n    // Other methods to be discussed later\n}\n----\n\nThis class uses the `TemplateRenderer` API to render templates. By default, Spring AI uses the `StTemplateRenderer` implementation, which is based on the open-source https://www.stringtemplate.org/[StringTemplate] engine developed by Terence Parr. Template variables are identified by the `{}` syntax, but you can configure the delimiters to use other syntax as well.\n\n[source,java]\n----\npublic interface TemplateRenderer extends BiFunction<String, Map<String, Object>, String> {\n\n\t@Override\n\tString apply(String template, Map<String, Object> variables);\n\n}\n----\n\nSpring AI uses the `TemplateRenderer` interface to handle the actual substitution of variables into the template string.\nThe default implementation uses <<StringTemplate>>.\nYou can provide your own implementation of `TemplateRenderer` if you need custom logic.\nFor scenarios where no template rendering is required (e.g., the template string is already complete), you can use the provided `NoOpTemplateRenderer`.\n\n.Example using a custom StringTemplate renderer with '<' and '>' delimiters\n[source,java]\n----\nPromptTemplate promptTemplate = PromptTemplate.builder()\n    .renderer(StTemplateRenderer.builder().startDelimiterToken('<').endDelimiterToken('>').build())\n    .template(\"\"\"\n            Tell me the names of 5 movies whose soundtrack was composed by <composer>.\n            \"\"\")\n    .build();\n\nString prompt = promptTemplate.render(Map.of(\"composer\", \"John Williams\"));\n----\n\nThe interfaces implemented by this class support different aspects of prompt creation:\n\n`PromptTemplateStringActions` focuses on creating and rendering prompt strings, representing the most basic form of prompt generation.\n\n`PromptTemplateMessageActions` is tailored for prompt creation through the generation and manipulation of `Message` objects.\n\n`PromptTemplateActions` is designed to return the `Prompt` object, which can be passed to `ChatModel` for generating a response.\n\nWhile these interfaces might not be used extensively in many projects, they show the different approaches to prompt creation.\n\nThe implemented interfaces are\n\n[source,java]\n----\npublic interface PromptTemplateStringActions {\n\n\tString render();\n\n\tString render(Map<String, Object> model);\n\n}\n----\n\nThe method `String render()`: Renders a prompt template into a final string format without external input, suitable for templates without placeholders or dynamic content.\n\nThe method `String render(Map<String, Object> model)`: Enhances rendering functionality to include dynamic content. It uses a `Map<String, Object>` where map keys are placeholder names in the prompt template, and values are the dynamic content to be inserted.\n\n[source,java]\n----\npublic interface PromptTemplateMessageActions {\n\n\tMessage createMessage();\n\n    Message createMessage(List<Media> mediaList);\n\n\tMessage createMessage(Map<String, Object> model);\n\n}\n----\n\nThe method `Message createMessage()`: Creates a `Message` object without additional data, used for static or predefined message content.\n\nThe method `Message createMessage(List<Media> mediaList)`: Creates a `Message` object with static textual and media content.\n\nThe method `Message createMessage(Map<String, Object> model)`: Extends message creation to integrate dynamic content, accepting a `Map<String, Object>` where each entry represents a placeholder in the message template and its corresponding dynamic value.\n\n\n[source,java]\n----\npublic interface PromptTemplateActions extends PromptTemplateStringActions {\n\n\tPrompt create();\n\n\tPrompt create(ChatOptions modelOptions);\n\n\tPrompt create(Map<String, Object> model);\n\n\tPrompt create(Map<String, Object> model, ChatOptions modelOptions);\n\n}\n----\n\nThe method `Prompt create()`: Generates a `Prompt` object without external data inputs, ideal for static or predefined prompts.\n\nThe method `Prompt create(ChatOptions modelOptions)`: Generates a `Prompt` object without external data inputs and with specific options for the chat request.\n\nThe method `Prompt create(Map<String, Object> model)`: Expands prompt creation capabilities to include dynamic content, taking a `Map<String, Object>` where each map entry is a placeholder in the prompt template and its associated dynamic value.\n\nThe method `Prompt create(Map<String, Object> model, ChatOptions modelOptions)`: Expands prompt creation capabilities to include dynamic content, taking a `Map<String, Object>` where each map entry is a placeholder in the prompt template and its associated dynamic value, and specific options for the chat request.\n\n== Example Usage\n\nA simple example taken from the https://github.com/Azure-Samples/spring-ai-azure-workshop/blob/main/2-README-prompt-templating.md[AI Workshop on PromptTemplates] is shown below.\n\n[source,java]\n----\nPromptTemplate promptTemplate = new PromptTemplate(\"Tell me a {adjective} joke about {topic}\");\n\nPrompt prompt = promptTemplate.create(Map.of(\"adjective\", adjective, \"topic\", topic));\n\nreturn chatModel.call(prompt).getResult();\n----\n\nAnother example taken from the https://github.com/Azure-Samples/spring-ai-azure-workshop/blob/main/3-README-prompt-roles.md[AI Workshop on Roles] is shown below.\n\n[source,java]\n----\nString userText = \"\"\"\n    Tell me about three famous pirates from the Golden Age of Piracy and why they did.\n    Write at least a sentence for each pirate.\n    \"\"\";\n\nMessage userMessage = new UserMessage(userText);\n\nString systemText = \"\"\"\n  You are a helpful AI assistant that helps people find information.\n  Your name is {name}\n  You should reply to the user's request with your name and also in the style of a {voice}.\n  \"\"\";\n\nSystemPromptTemplate systemPromptTemplate = new SystemPromptTemplate(systemText);\nMessage systemMessage = systemPromptTemplate.createMessage(Map.of(\"name\", name, \"voice\", voice));\n\nPrompt prompt = new Prompt(List.of(userMessage, systemMessage));\n\nList<Generation> response = chatModel.call(prompt).getResults();\n----\n\nThis shows how you can build up the `Prompt` instance by using the `SystemPromptTemplate` to create a `Message` with the system role passing in placeholder values.\nThe message with the role `user` is then combined with the message of the role `system` to form the prompt.\nThe prompt is then passed to the ChatModel to get a generative response.\n\n=== Using a custom template renderer\n\nYou can use a custom template renderer by implementing the `TemplateRenderer` interface and passing it to the `PromptTemplate` constructor. You can also keep using the default `StTemplateRenderer`, but with a custom configuration.\n\nBy default, template variables are identified by the `{}` syntax. If you're planning to include JSON in your prompt, you might want to use a different syntax to avoid conflicts with JSON syntax. For example, you can use the `<` and `>` delimiters.\n\n[source,java]\n----\nPromptTemplate promptTemplate = PromptTemplate.builder()\n    .renderer(StTemplateRenderer.builder().startDelimiterToken('<').endDelimiterToken('>').build())\n    .template(\"\"\"\n            Tell me the names of 5 movies whose soundtrack was composed by <composer>.\n            \"\"\")\n    .build();\n\nString prompt = promptTemplate.render(Map.of(\"composer\", \"John Williams\"));\n----\n\n=== Using resources instead of raw Strings\n\nSpring AI supports the `org.springframework.core.io.Resource` abstraction, so you can put prompt data in a file that can directly be used in a `PromptTemplate`.\nFor example, you can define a field in your Spring managed component to retrieve the `Resource`.\n\n[source,java]\n----\n@Value(\"classpath:/prompts/system-message.st\")\nprivate Resource systemResource;\n----\n\nand then pass that resource to the `SystemPromptTemplate` directly.\n\n[source,java]\n----\nSystemPromptTemplate systemPromptTemplate = new SystemPromptTemplate(systemResource);\n----\n\n== Prompt Engineering\n\nIn generative AI, the creation of prompts is a crucial task for developers.\nThe quality and structure of these prompts significantly influence the effectiveness of the AI's output.\nInvesting time and effort in designing thoughtful prompts can greatly improve the results from the AI.\n\nSharing and discussing prompts is a common practice in the AI community.\nThis collaborative approach not only creates a shared learning environment but also leads to the identification and use of highly effective prompts.\n\nResearch in this area often involves analyzing and comparing different prompts to assess their effectiveness in various situations.\nFor example, a significant study demonstrated that starting a prompt with \"Take a deep breath and work on this problem step by step\" significantly enhanced problem-solving efficiency.\nThis highlights the impact that well-chosen language can have on generative AI systems' performance.\n\nGrasping the most effective use of prompts, particularly with the rapid advancement of AI technologies, is a continuous challenge.\nYou should recognize the importance of prompt engineering and consider using insights from the community and research to improve prompt creation strategies.\n\n=== Creating effective prompts\n\nWhen developing prompts, it's important to integrate several key components to ensure clarity and effectiveness:\n\n* *Instructions*: Offer clear and direct instructions to the AI, similar to how you would communicate with a person. This clarity is essential for helping the AI \"understand\" what is expected.\n\n* *External Context*: Include relevant background information or specific guidance for the AI's response when necessary. This \"external context\" frames the prompt and aids the AI in grasping the overall scenario.\n\n* *User Input*: This is the straightforward part - the user's direct request or question forming the core of the prompt.\n\n* *Output Indicator*: This aspect can be tricky. It involves specifying the desired format for the AI's response, such as JSON. However, be aware that the AI might not always adhere strictly to this format. For instance, it might prepend a phrase like \"here is your JSON\" before the actual JSON data, or sometimes generate a JSON-like structure that is not accurate.\n\nProviding the AI with examples of the anticipated question and answer format can be highly beneficial when crafting prompts.\nThis practice helps the AI \"understand\" the structure and intent of your query, leading to more precise and relevant responses.\nWhile this documentation does not delve deeply into these techniques, they provide a starting point for further exploration in AI prompt engineering.\n\nFollowing is a list of resources for further investigation.\n\n==== Simple Techniques\n\n* *https://www.promptingguide.ai/introduction/examples.en#text-summarization[Text Summarization]*: +\nReduces extensive text into concise summaries, capturing key points and main ideas while omitting less critical details.\n\n* *https://www.promptingguide.ai/introduction/examples.en#question-answering[Question Answering]*: +\nFocuses on deriving specific answers from provided text, based on user-posed questions. It's about pinpointing and extracting relevant information in response to queries.\n\n* *https://www.promptingguide.ai/introduction/examples.en#text-classification[Text Classification]*: +\nSystematically categorizes text into predefined categories or groups, analyzing the text and assigning it to the most fitting category based on its content.\n\n* *https://www.promptingguide.ai/introduction/examples.en#conversation[Conversation]*: +\nCreates interactive dialogues where the AI can engage in back-and-forth communication with users, simulating a natural conversation flow.\n\n* *https://www.promptingguide.ai/introduction/examples.en#code-generation[Code Generation]*: +\nGenerates functional code snippets based on specific user requirements or descriptions, translating natural language instructions into executable code.\n\n==== Advanced Techniques\n\n* *https://www.promptingguide.ai/techniques/zeroshot[Zero-shot], https://www.promptingguide.ai/techniques/fewshot[Few-shot Learning]*: +\nEnables the model to make accurate predictions or responses with minimal to no prior examples of the specific problem type, understanding and acting on new tasks using learned generalizations.\n\n* *https://www.promptingguide.ai/techniques/cot[Chain-of-Thought]*: +\nLinks multiple AI responses to create a coherent and contextually aware conversation. It helps the AI maintain the thread of the discussion, ensuring relevance and continuity.\n\n* *https://www.promptingguide.ai/techniques/react[ReAct (Reason + Act)]*: +\nIn this method, the AI first analyzes (reasons about) the input, then determines the most appropriate course of action or response. It combines understanding with decision-making.\n\n==== Microsoft Guidance\n\n* *https://github.com/microsoft/guidance[Framework for Prompt Creation and Optimization]*: +\nMicrosoft offers a structured approach to developing and refining prompts. This framework guides users in creating effective prompts that elicit the desired responses from AI models, optimizing the interaction for clarity and efficiency.\n\n== Tokens\n\nTokens are essential in how AI models process text, acting as a bridge that converts words (as we understand them) into a format that AI models can process.\nThis conversion occurs in two stages: words are transformed into tokens upon input, and these tokens are then converted back into words in the output.\n\nTokenization, the process of breaking down text into tokens, is fundamental to how AI models comprehend and process language.\nThe AI model works with this tokenized format to understand and respond to prompts.\n\nTo better understand tokens, think of them as portions of words. Typically, a token represents about three-quarters of a word. For instance, the complete works of Shakespeare, totaling roughly 900,000 words, would translate to around 1.2 million tokens.\n\nExperiment with the https://platform.openai.com/tokenizer[OpenAI Tokenizer UI] to see how words are converted into tokens.\n\nTokens have practical implications beyond their technical role in AI processing, especially regarding billing and model capabilities:\n\n* Billing: AI model services often bill based on token usage. Both the input (prompt) and the output (response) contribute to the total token count, making shorter prompts more cost-effective.\n\n* Model Limits: Different AI models have varying token limits, defining their \"context window\" – the maximum amount of information they can process at a time. For example, GPT-3's limit is 4K tokens, while other models like Claude 2 and Meta Llama 2 have limits of 100K tokens, and some research models can handle up to 1 million tokens.\n\n* Context Window: A model's token limit determines its context window. Inputs exceeding this limit are not processed by the model. It's crucial to send only the minimal effective set of information for processing. For example, when inquiring about \"Hamlet,\" there's no need to include tokens from all of Shakespeare's other works.\n\n* Response Metadata: The metadata of a response from an AI model includes the number of tokens used, a vital piece of information for managing usage and costs.\n"

    "content": "[[rag]]\n= Retrieval Augmented Generation\n\nRetrieval Augmented Generation (RAG) is a technique useful to overcome the limitations of large language models\nthat struggle with long-form content, factual accuracy, and context-awareness.\n\nSpring AI supports RAG by providing a modular architecture that allows you to build custom RAG flows yourself\nor use out-of-the-box RAG flows using the `Advisor` API.\n\nNOTE: Learn more about Retrieval Augmented Generation in the xref:concepts.adoc#concept-rag[concepts] section.\n\n== Advisors\n\nSpring AI provides out-of-the-box support for common RAG flows using the `Advisor` API.\n\nTo use the `QuestionAnswerAdvisor` or `VectorStoreChatMemoryAdvisor`, you need to add the `spring-ai-advisors-vector-store` dependency to your project:\n\n[source,xml]\n----\n<dependency>\n   <groupId>org.springframework.ai</groupId>\n   <artifactId>spring-ai-advisors-vector-store</artifactId>\n</dependency>\n----\n\n=== QuestionAnswerAdvisor\n\nA vector database stores data that the AI model is unaware of. When a user question is sent to the AI model, a `QuestionAnswerAdvisor` queries the vector database for documents related to the user question.\n\nThe response from the vector database is appended to the user text to provide context for the AI model to generate a response.\n\nAssuming you have already loaded data into a `VectorStore`, you can perform Retrieval Augmented Generation (RAG) by providing an instance of `QuestionAnswerAdvisor` to the `ChatClient`.\n\n[source,java]\n----\nChatResponse response = ChatClient.builder(chatModel)\n        .build().prompt()\n        .advisors(QuestionAnswerAdvisor.builder(vectorStore).build())\n        .user(userText)\n        .call()\n        .chatResponse();\n----\n\nIn this example, the `QuestionAnswerAdvisor` will perform a similarity search over all documents in the Vector Database. To restrict the types of documents that are searched, the `SearchRequest` takes an SQL like filter expression that is portable across all `VectorStores`.\n\nThis filter expression can be configured when creating the `QuestionAnswerAdvisor` and hence will always apply to all `ChatClient` requests, or it can be provided at runtime per request.\n\nHere is how to create an instance of `QuestionAnswerAdvisor` where the threshold is `0.8` and to return the top `6` results.\n\n[source,java]\n----\nvar qaAdvisor = QuestionAnswerAdvisor.builder(vectorStore)\n        .searchRequest(SearchRequest.builder().similarityThreshold(0.8d).topK(6).build())\n        .build();\n----\n\n==== Dynamic Filter Expressions\n\nUpdate the `SearchRequest` filter expression at runtime using the `FILTER_EXPRESSION` advisor context parameter:\n\n[source,java]\n----\nChatClient chatClient = ChatClient.builder(chatModel)\n    .defaultAdvisors(QuestionAnswerAdvisor.builder(vectorStore)\n        .searchRequest(SearchRequest.builder().build())\n        .build())\n    .build();\n\n// Update filter expression at runtime\nString content = this.chatClient.prompt()\n    .user(\"Please answer my question XYZ\")\n    .advisors(a -> a.param(QuestionAnswerAdvisor.FILTER_EXPRESSION, \"type == 'Spring'\"))\n    .call()\n    .content();\n----\n\nThe `FILTER_EXPRESSION` parameter allows you to dynamically filter the search results based on the provided expression.\n\n==== Custom Template\n\nThe `QuestionAnswerAdvisor` uses a default template to augment the user question with the retrieved documents. You can customize this behavior by providing your own `PromptTemplate` object via the `.promptTemplate()` builder method.\n\nNOTE: The `PromptTemplate` provided here customizes how the advisor merges retrieved context with the user query. This is distinct from configuring a `TemplateRenderer` on the `ChatClient` itself (using `.templateRenderer()`), which affects the rendering of the initial user/system prompt content *before* the advisor runs. See xref:api/chatclient.adoc#_prompt_templates[ChatClient Prompt Templates] for more details on client-level template rendering.\n\nThe custom `PromptTemplate` can use any `TemplateRenderer` implementation (by default, it uses `StPromptTemplate` based on the https://www.stringtemplate.org/[StringTemplate] engine). The important requirement is that the template must contain the following two placeholders:\n\n* a `query` placeholder to receive the user question.\n* a `question_answer_context` placeholder to receive the retrieved context.\n\n[source,java]\n----\nPromptTemplate customPromptTemplate = PromptTemplate.builder()\n    .renderer(StTemplateRenderer.builder().startDelimiterToken('<').endDelimiterToken('>').build())\n    .template(\"\"\"\n            <query>\n\n            Context information is below.\n\n\t\t\t---------------------\n\t\t\t<question_answer_context>\n\t\t\t---------------------\n\n\t\t\tGiven the context information and no prior knowledge, answer the query.\n\n\t\t\tFollow these rules:\n\n\t\t\t1. If the answer is not in the context, just say that you don't know.\n\t\t\t2. Avoid statements like \"Based on the context...\" or \"The provided information...\".\n            \"\"\")\n    .build();\n\n    String question = \"Where does the adventure of Anacletus and Birba take place?\";\n\n    QuestionAnswerAdvisor qaAdvisor = QuestionAnswerAdvisor.builder(vectorStore)\n        .promptTemplate(customPromptTemplate)\n        .build();\n\n    String response = ChatClient.builder(chatModel).build()\n        .prompt(question)\n        .advisors(qaAdvisor)\n        .call()\n        .content();\n----\n\nNOTE: The `QuestionAnswerAdvisor.Builder.userTextAdvise()` method is deprecated in favor of using `.promptTemplate()` for more flexible customization.\n\n=== RetrievalAugmentationAdvisor\n\nSpring AI includes a xref:api/retrieval-augmented-generation.adoc#modules[library of RAG modules] that you can use to build your own RAG flows.\nThe `RetrievalAugmentationAdvisor` is an `Advisor` providing an out-of-the-box implementation for the most common RAG flows,\nbased on a modular architecture.\n\nTo use the `RetrievalAugmentationAdvisor`, you need to add the `spring-ai-rag` dependency to your project:\n\n[source,xml]\n----\n<dependency>\n   <groupId>org.springframework.ai</groupId>\n   <artifactId>spring-ai-rag</artifactId>\n</dependency>\n----\n\n==== Sequential RAG Flows\n\n===== Naive RAG\n\n[source,java]\n----\nAdvisor retrievalAugmentationAdvisor = RetrievalAugmentationAdvisor.builder()\n        .documentRetriever(VectorStoreDocumentRetriever.builder()\n                .similarityThreshold(0.50)\n                .vectorStore(vectorStore)\n                .build())\n        .build();\n\nString answer = chatClient.prompt()\n        .advisors(retrievalAugmentationAdvisor)\n        .user(question)\n        .call()\n        .content();\n----\n\nBy default, the `RetrievalAugmentationAdvisor` does not allow the retrieved context to be empty. When that happens,\nit instructs the model not to answer the user query. You can allow empty context as follows.\n\n[source,java]\n----\nAdvisor retrievalAugmentationAdvisor = RetrievalAugmentationAdvisor.builder()\n        .documentRetriever(VectorStoreDocumentRetriever.builder()\n                .similarityThreshold(0.50)\n                .vectorStore(vectorStore)\n                .build())\n        .queryAugmenter(ContextualQueryAugmenter.builder()\n                .allowEmptyContext(true)\n                .build())\n        .build();\n\nString answer = chatClient.prompt()\n        .advisors(retrievalAugmentationAdvisor)\n        .user(question)\n        .call()\n        .content();\n----\n\nThe `VectorStoreDocumentRetriever` accepts a `FilterExpression` to filter the search results based on metadata.\nYou can provide one when instantiating the `VectorStoreDocumentRetriever` or at runtime per request,\nusing the `FILTER_EXPRESSION` advisor context parameter.\n\n[source,java]\n----\nAdvisor retrievalAugmentationAdvisor = RetrievalAugmentationAdvisor.builder()\n        .documentRetriever(VectorStoreDocumentRetriever.builder()\n                .similarityThreshold(0.50)\n                .vectorStore(vectorStore)\n                .build())\n        .build();\n\nString answer = chatClient.prompt()\n        .advisors(retrievalAugmentationAdvisor)\n        .advisors(a -> a.param(VectorStoreDocumentRetriever.FILTER_EXPRESSION, \"type == 'Spring'\"))\n        .user(question)\n        .call()\n        .content();\n----\n\nSee xref:api/retrieval-augmented-generation.adoc#_vectorstoredocumentretriever[VectorStoreDocumentRetriever] for more information.\n\n===== Advanced RAG\n\n[source,java]\n----\nAdvisor retrievalAugmentationAdvisor = RetrievalAugmentationAdvisor.builder()\n        .queryTransformers(RewriteQueryTransformer.builder()\n                .chatClientBuilder(chatClientBuilder.build().mutate())\n                .build())\n        .documentRetriever(VectorStoreDocumentRetriever.builder()\n                .similarityThreshold(0.50)\n                .vectorStore(vectorStore)\n                .build())\n        .build();\n\nString answer = chatClient.prompt()\n        .advisors(retrievalAugmentationAdvisor)\n        .user(question)\n        .call()\n        .content();\n----\n\nYou can also use the `DocumentPostProcessor` API to post-process the retrieved documents before passing them to the model. For example, you can use such an interface to perform re-ranking of the retrieved documents based on their relevance to the query, remove irrelevant or redundant documents, or compress the content of each document to reduce noise and redundancy.\n\n[[modules]]\n== Modules\n\nSpring AI implements a Modular RAG architecture inspired by the concept of modularity detailed in the paper\n\"https://arxiv.org/abs/2407.21059[Modular RAG: Transforming RAG Systems into LEGO-like Reconfigurable Frameworks]\".\n\n=== Pre-Retrieval\n\nPre-Retrieval modules are responsible for processing the user query to achieve the best possible retrieval results.\n\n==== Query Transformation\n\nA component for transforming the input query to make it more effective for retrieval tasks, addressing challenges\nsuch as poorly formed queries, ambiguous terms, complex vocabulary, or unsupported languages.\n\nIMPORTANT: When using a `QueryTransformer`, it's recommended to configure the `ChatClient.Builder` with a low temperature (e.g., 0.0) to ensure more deterministic and accurate results, improving retrieval quality.  The default temperature for most chat models is typically too high for optimal query transformation, leading to reduced retrieval effectiveness.\n\n===== CompressionQueryTransformer\n\nA `CompressionQueryTransformer` uses a large language model to compress a conversation history and a follow-up query\ninto a standalone query that captures the essence of the conversation.\n\nThis transformer is useful when the conversation history is long and the follow-up query is related\nto the conversation context.\n\n[source,java]\n----\nQuery query = Query.builder()\n        .text(\"And what is its second largest city?\")\n        .history(new UserMessage(\"What is the capital of Denmark?\"),\n                new AssistantMessage(\"Copenhagen is the capital of Denmark.\"))\n        .build();\n\nQueryTransformer queryTransformer = CompressionQueryTransformer.builder()\n        .chatClientBuilder(chatClientBuilder)\n        .build();\n\nQuery transformedQuery = queryTransformer.transform(query);\n----\n\nThe prompt used by this component can be customized via the `promptTemplate()` method available in the builder.\n\n===== RewriteQueryTransformer\n\nA `RewriteQueryTransformer` uses a large language model to rewrite a user query to provide better results when\nquerying a target system, such as a vector store or a web search engine.\n\nThis transformer is useful when the user query is verbose, ambiguous, or contains irrelevant information\nthat may affect the quality of the search results.\n\n[source,java]\n----\nQuery query = new Query(\"I'm studying machine learning. What is an LLM?\");\n\nQueryTransformer queryTransformer = RewriteQueryTransformer.builder()\n        .chatClientBuilder(chatClientBuilder)\n        .build();\n\nQuery transformedQuery = queryTransformer.transform(query);\n----\n\nThe prompt used by this component can be customized via the `promptTemplate()` method available in the builder.\n\n===== TranslationQueryTransformer\n\nA `TranslationQueryTransformer` uses a large language model to translate a query to a target language that is supported\nby the embedding model used to generate the document embeddings. If the query is already in the target language,\nit is returned unchanged. If the language of the query is unknown, it is also returned unchanged.\n\nThis transformer is useful when the embedding model is trained on a specific language and the user query\nis in a different language.\n\n[source,java]\n----\nQuery query = new Query(\"Hvad er Danmarks hovedstad?\");\n\nQueryTransformer queryTransformer = TranslationQueryTransformer.builder()\n        .chatClientBuilder(chatClientBuilder)\n        .targetLanguage(\"english\")\n        .build();\n\nQuery transformedQuery = queryTransformer.transform(query);\n----\n\nThe prompt used by this component can be customized via the `promptTemplate()` method available in the builder.\n\n==== Query Expansion\n\nA component for expanding the input query into a list of queries, addressing challenges such as poorly formed queries\nby providing alternative query formulations, or by breaking down complex problems into simpler sub-queries.\n\n===== MultiQueryExpander\n\nA `MultiQueryExpander` uses a large language model to expand a query into multiple semantically diverse variations\nto capture different perspectives, useful for retrieving additional contextual information and increasing the chances\nof finding relevant results.\n\n[source,java]\n----\nMultiQueryExpander queryExpander = MultiQueryExpander.builder()\n    .chatClientBuilder(chatClientBuilder)\n    .numberOfQueries(3)\n    .build();\nList<Query> queries = queryExpander.expand(new Query(\"How to run a Spring Boot app?\"));\n----\n\nBy default, the `MultiQueryExpander` includes the original query in the list of expanded queries.

    "content": "[[StructuredOutputConverter]]\n\n= Structured Output Converter\n\nThe ability of LLMs to produce structured outputs is important for downstream applications that rely on reliably parsing output values.\nDevelopers want to quickly turn results from an AI model into data types, such as JSON, XML or Java classes, that can be passed to other application functions and methods.\n\nThe Spring AI `Structured Output Converters` help to convert the LLM output into a structured format.\nAs shown in the following diagram, this approach operates around the LLM text completion endpoint:\n\nimage::structured-output-architecture.jpg[Structured Output Converter Architecture, width=900, align=\"center\"]\n\nGenerating structured outputs from Large Language Models (LLMs) using generic completion APIs requires careful handling of inputs and outputs. The structured output converter plays a crucial role before and after the LLM call, ensuring the desired output structure is achieved.\n\nBefore the LLM call, the converter appends format instructions to the prompt, providing explicit guidance to the models on generating the desired output structure. These instructions act as a blueprint, shaping the model's response to conform to the specified format.\n\nNOTE: As more AI models natively support structured outputs, you can leverage this capability using the xref:api/chatclient.adoc#_native_structured_output[Native Structured Output] feature with `AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT`. This approach uses the generated JSON schema directly with the model's native structured output API, eliminating the need for pre-prompt formatting instructions and providing more reliable results.\n\nAfter the LLM call, the converter takes the model's output text and transforms it into instances of the structured type. This conversion process involves parsing the raw text output and mapping it to the corresponding structured data representation, such as JSON, XML, or domain-specific data structures.\n\nTIP: The `StructuredOutputConverter` is a best effort to convert the model output into a structured output.\nThe AI Model is not guaranteed to return the structured output as requested.\nThe model may not understand the prompt or be unable to generate the structured output as requested.\nConsider implementing a validation mechanism to ensure the model output is as expected.\n\nTIP: The `StructuredOutputConverter` is not used for LLM xref:api/tools.adoc[Tool Calling], as this feature inherently provides structured outputs by default.\n\n== Structured Output API\n\nThe `StructuredOutputConverter` interface allows you to obtain structured output, such as mapping the output to a Java class or an array of values from the text-based AI Model output.\nThe interface definition is:\n\n[source,java]\n----\npublic interface StructuredOutputConverter<T> extends Converter<String, T>, FormatProvider {\n\n}\n----\n\nIt combines the Spring https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/convert/converter/Converter.html[Converter<String, T>] interface and the `FormatProvider` interface\n\n[source,java]\n----\npublic interface FormatProvider {\n\tString getFormat();\n}\n----\n\nThe following diagram shows the data flow when using the structured output API.\n\nimage::structured-output-api.jpg[Structured Output API, width=900, align=\"center\"]\n\n\nThe `FormatProvider` supplies specific formatting guidelines to the AI Model, enabling it to produce text outputs that can be converted into the designated target type `T` using the `Converter`. Here is an example of such formatting instructions:\n\n----\n  Your response should be in JSON format.\n  The data structure for the JSON should match this Java class: java.util.HashMap\n  Do not include any explanations, only provide a RFC8259 compliant JSON response following this format without deviation.\n----\n\nThe format instructions are most often appended to the end of the user input using the xref:api/prompt.adoc#_prompttemplate[PromptTemplate] like this:\n\n[source,java]\n----\n    StructuredOutputConverter outputConverter = ...\n    String userInputTemplate = \"\"\"\n        ... user text input ....\n        {format}\n        \"\"\"; // user input with a \"format\" placeholder.\n    Prompt prompt = new Prompt(\n            PromptTemplate.builder()\n\t\t\t\t\t\t.template(this.userInputTemplate)\n\t\t\t\t\t\t.variables(Map.of(..., \"format\", this.outputConverter.getFormat())) // replace the \"format\" placeholder with the converter's format.\n\t\t\t\t\t\t.build().createMessage()\n    );\n----\n\nThe Converter<String, T> is responsible to transform output text from the model into instances of the specified type `T`.\n\n=== Available Converters\n\nCurrently, Spring AI provides `AbstractConversionServiceOutputConverter`, `AbstractMessageOutputConverter`, `BeanOutputConverter`, `MapOutputConverter` and `ListOutputConverter` implementations:\n\nimage::structured-output-hierarchy4.jpg[Structured Output Class Hierarchy, width=900, align=\"center\"]\n\n* `AbstractConversionServiceOutputConverter<T>` - Offers a pre-configured link:https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/convert/support/GenericConversionService.html[GenericConversionService] for transforming LLM output into the desired format. No default `FormatProvider` implementation is provided.\n* `AbstractMessageOutputConverter<T>` - Supplies a pre-configured https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/jms/support/converter/MessageConverter.html[MessageConverter] for converting LLM output into the desired format. No default `FormatProvider` implementation is provided.\n* `BeanOutputConverter<T>` - Configured with a designated Java class (e.g., Bean) or a link:https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/ParameterizedTypeReference.html[ParameterizedTypeReference], this converter employs a `FormatProvider` implementation that directs the AI Model to produce a JSON response compliant with a `DRAFT_2020_12`, `JSON Schema` derived from the specified Java class. Subsequently, it utilizes an `JsonMapper` to deserialize the JSON output into a Java object instance of the target class.\n* `MapOutputConverter` - Extends the functionality of `AbstractMessageOutputConverter` with a `FormatProvider` implementation that guides the AI Model to generate an RFC8259 compliant JSON response. Additionally, it incorporates a converter implementation that utilizes the provided `MessageConverter` to translate the JSON payload into a `java.util.Map<String, Object>` instance.\n* `ListOutputConverter` - Extends the  `AbstractConversionServiceOutputConverter` and includes a `FormatProvider` implementation tailored for comma-delimited list output. The converter implementation employs the provided `ConversionService` to transform the model text output into a `java.util.List`.\n\n== Using Converters\n\nThe following sections provide guides how to use the available converters to generate structured outputs.\n\n=== Bean Output Converter\n\nThe following example shows how to use `BeanOutputConverter` to generate the filmography for an actor.\n\nThe target record representing actor's filmography:\n\n[source,java]\n----\nrecord ActorsFilms(String actor, List<String> movies) {\n}\n----\n\nHere is how to apply the BeanOutputConverter using the high-level, fluent `ChatClient` API:\n\n[source,java]\n----\nActorsFilms actorsFilms = ChatClient.create(chatModel).prompt()\n        .user(u -> u.text(\"Generate the filmography of 5 movies for {actor}.\")\n                    .param(\"actor\", \"Tom Hanks\"))\n        .call()\n        .entity(ActorsFilms.class);\n----\n\nor using the low-level `ChatModel` API directly:\n\n[source,java]\n----\nBeanOutputConverter<ActorsFilms> beanOutputConverter =\n    new BeanOutputConverter<>(ActorsFilms.class);\n\nString format = this.beanOutputConverter.getFormat();\n\nString actor = \"Tom Hanks\";\n\nString template = \"\"\"\n        Generate the filmography of 5 movies for {actor}.\n        {format}\n        \"\"\";\n\nGeneration generation = chatModel.call(\n    PromptTemplate.builder().template(this.template).variables(Map.of(\"actor\", this.actor, \"format\", this.format)).build().create()).getResult();\n\nActorsFilms actorsFilms = this.beanOutputConverter.convert(this.generation.getOutput().getText());\n----\n\n=== Property Ordering in Generated Schema\n\nThe `BeanOutputConverter` supports custom property ordering in the generated JSON schema through the `@JsonPropertyOrder` annotation.\nThis annotation allows you to specify the exact sequence in which properties should appear in the schema, regardless of their declaration order in the class or record.\n\nFor example, to ensure specific ordering of properties in the `ActorsFilms` record:\n\n[source,java]\n----\n@JsonPropertyOrder({\"actor\", \"movies\"})\nrecord ActorsFilms(String actor, List<String> movies) {}\n----\n\nThis annotation works with both records and regular Java classes.\n\n==== Generic Bean Types\n\nUse the `ParameterizedTypeReference` constructor to specify a more complex target class structure.\nFor example, to represent a list of actors and their filmographies:\n\n[source,java]\n----\nList<ActorsFilms> actorsFilms = ChatClient.create(chatModel).prompt()\n        .user(\"Generate the filmography of 5 movies for Tom Hanks and Bill Murray.\")\n        .call()\n        .entity(new ParameterizedTypeReference<List<ActorsFilms>>() {});\n----\n\nor using the low-level `ChatModel` API directly:\n\n[source,java]\n----\nBeanOutputConverter<List<ActorsFilms>> outputConverter = new BeanOutputConverter<>(\n        new ParameterizedTypeReference<List<ActorsFilms>>() { });\n\nString format = this.outputConverter.getFormat();\nString template = \"\"\"\n        Generate the filmography of 5 movies for Tom Hanks and Bill Murray.\n        {format}\n        \"\"\";\n\nPrompt prompt = PromptTemplate.builder().template(this.template).variables(Map.of(\"format\", this.format)).build().create();\n\nGeneration generation = chatModel.call(this.prompt).getResult();\n\nList<ActorsFilms> actorsFilms = this.outputConverter.convert(this.generation.getOutput().getText());\n----\n\n=== Map Output Converter\n\nThe following snippet shows how to use `MapOutputConverter` to convert the model output to a list of numbers in a map.\n\n[source,java]\n----\nMap<String, Object> result = ChatClient.create(chatModel).prompt()\n        .user(u -> u.text(\"Provide me a List of {subject}\")\n                    .param(\"subject\", \"an array of numbers from 1 to 9 under they key name 'numbers'\"))\n        .call()\n        .entity(new ParameterizedTypeReference<Map<String, Object>>() {});\n----\n\nor using the low-level `ChatModel` API directly:\n\n[source,java]\n----\nMapOutputConverter mapOutputConverter = new MapOutputConverter();\n\nString format = this.mapOutputConverter.getFormat();\nString template = \"\"\"\n        Provide me a List of {subject}\n        {format}\n        \"\"\";\n\nPrompt prompt = PromptTemplate.builder().template(this.template)\n.variables(Map.of(\"subject\", \"an array of numbers from 1 to 9 under they key name 'numbers'\", \"format\", this.format)).build().create();\n\nGeneration generation = chatModel.call(this.prompt).getResult();\n\nMap<String, Object> result = this.mapOutputConverter.convert(this.generation.getOutput().getText());\n----\n\n=== List Output Converter\n\nThe following snippet shows how to use `ListOutputConverter` to convert the model output into a list of ice cream flavors.\n\n[source,java]\n----\nList<String> flavors = ChatClient.create(chatModel).prompt()\n                .user(u -> u.text(\"List five {subject}\")\n                            .param(\"subject\", \"ice cream flavors\"))\n                .call()\n                .entity(new ListOutputConverter(new DefaultConversionService()));\n----\n\nor using the low-level `ChatModel API` directly:\n\n[source,java]\n----\nListOutputConverter listOutputConverter = new ListOutputConverter(new DefaultConversionService());\n\nString format = this.listOutputConverter.getFormat();\nString template = \"\"\"\n        List five {subject}\n        {format}\n        \"\"\";\n\nPrompt prompt = PromptTemplate.builder().template(this.template).variables(Map.of(\"subject\", \"ice cream flavors\", \"format\", this.format)).build().create();\n\nGeneration generation = this.chatModel.call(this.prompt).getResult();\n\nList<String> list = this.listOutputConverter.convert(this.generation.getOutput().getText());\n----\n\n== Native Structured Output\n\nMany modern AI models now provide native support for structured output, which offers more reliable results compared to prompt-based formatting. Spring AI supports this through the xref:api/chatclient.adoc#_native_structured_output[Native Structured Output] feature.\n\nWhen using native structured output, the JSON schema generated by `BeanOutputConverter` is sent directly to the model's structured output API, eliminating the need for format instructions in the prompt. This approach provides:\n\n* **Higher reliability**: The model guarantees output conforming to the schema\n* **Cleaner prompts**: No need to append format instructions\n* **Better performance**: Models can optimize for structured output internally\n\n=== Using Native Structured Output\n\nTo enable native structured output, use the `AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT` parameter:\n\n[source,java]\n----\nActorsFilms actorsFilms = ChatClient.create(chatModel).prompt()\n    .advisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT)\n    .user(\"Generate the filmography for a random actor.\")\n    .call()\n    .entity(ActorsFilms.class);\n----\n\nYou can also set this globally using `defaultAdvisors()` on the `ChatClient.Builder`:\n\n[source,java]\n----\n@Bean\nChatClient chatClient(ChatClient.Builder builder) {\n    return builder\n        .defaultAdvisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT)\n        .build();\n}\n----\n\n=== Supported Models for Native Structured Output\n\nThe following models currently support native structured output:\n\n* **OpenAI**: GPT-4o and later models with JSON Schema support\n* **Anthropic**: Claude 3.5 Sonnet and later models\n* **Google GenAI**: Gemini 1.5 Pro and later models\n* **Mistral AI**: Mistral Small and later models with JSON Schema support\n\nNOTE: Some AI models, such as OpenAI, don't support arrays of objects natively at the top level. In such cases, you can use the Spring AI default structured output conversion (without the native structured output advisor).\n\n=== Built-in JSON mode\n\nSome AI Models provide dedicated configuration options to generate structured (usually JSON) output.\n\n* xref:api/chat/openai-chat.adoc#_structured_outputs[OpenAI Structured Outputs] can ensure your model generates responses conforming strictly to your provided JSON Schema. You can choose between the `JSON_OBJECT` that guarantees the message the model generates is valid JSON or `JSON_SCHEMA` with a supplied schema that guarantees the model will generate a response that matches your supplied schema (`spring.ai.openai.chat.options.responseFormat` option).\n* xref:api/chat/azure-openai-chat.adoc[Azure OpenAI] - provides a `spring.ai.azure.openai.chat.options.responseFormat` options specifying the format that the model must output. Setting to `{ \"type\": \"json_object\" }` enables JSON mode, which guarantees the message the model generates is valid JSON.\n* xref:api/chat/ollama-chat.adoc[Ollama] - provides a `spring.ai.ollama.chat.options.format` option to specify the format to return a response in. Currently, the only accepted value is `json`.\n* xref:api/chat/mistralai-chat.adoc[Mistral AI] - provides a `spring.ai.mistralai.chat.options.responseFormat` option to specify the format to return a response in. Setting it to `{ \"type\": \"json_object\" }` enables JSON mode, which guarantees the message the model generates is valid JSON. Additionally, setting it to `{ \"type\": \"json_schema\" }` with a supplied schema enables native structured output support, which guarantees the model will generate a response that matches your supplied schema.\n"

    "content": "= Evaluation Testing\n\nTesting AI applications requires evaluating the generated content to ensure the AI model has not produced a hallucinated response.\n\nOne method to evaluate the response is to use the AI model itself for evaluation. Select the best AI model for the evaluation, which may not be the same model used to generate the response.\n\nThe Spring AI interface for evaluating responses is `Evaluator`, defined as:\n\n[source,java]\n----\n@FunctionalInterface\npublic interface Evaluator {\n    EvaluationResponse evaluate(EvaluationRequest evaluationRequest);\n}\n----\n\nThe input to the evaluation is the `EvaluationRequest` defined as\n\n[source,java]\n----\npublic class EvaluationRequest {\n\n\tprivate final String userText;\n\n\tprivate final List<Content> dataList;\n\n\tprivate final String responseContent;\n\n\tpublic EvaluationRequest(String userText, List<Content> dataList, String responseContent) {\n\t\tthis.userText = userText;\n\t\tthis.dataList = dataList;\n\t\tthis.responseContent = responseContent;\n\t}\n\n  ...\n}\n----\n\n* `userText`: The raw input from the user as a `String`\n* `dataList`: Contextual data, such as from Retrieval Augmented Generation, appended to the raw input.\n* `responseContent`: The AI model's response content as a `String`\n\n== Relevancy Evaluator\n\nThe `RelevancyEvaluator` is an implementation of the `Evaluator` interface, designed to assess the relevance of AI-generated responses against provided context. This evaluator helps assess the quality of a RAG flow by determining if the AI model's response is relevant to the user's input with respect to the retrieved context.\n\nThe evaluation is based on the user input, the AI model's response, and the context information. It uses a prompt template to ask the AI model if the response is relevant to the user input and context.\n\nThis is the default prompt template used by the `RelevancyEvaluator`:\n\n[source,text]\n----\nYour task is to evaluate if the response for the query\nis in line with the context information provided.\n\nYou have two options to answer. Either YES or NO.\n\nAnswer YES, if the response for the query\nis in line with context information otherwise NO.\n\nQuery:\n{query}\n\nResponse:\n{response}\n\nContext:\n{context}\n\nAnswer:\n----\n\nNOTE: You can customize the prompt template by providing your own `PromptTemplate` object via the `.promptTemplate()` builder method. See xref:_custom_template[Custom Template] for details.\n\n== Usage in Integration Tests\n\nHere is an example of usage of the `RelevancyEvaluator` in an integration test, validating the result of a RAG flow using the `RetrievalAugmentationAdvisor`:\n\n[source,java]\n----\n@Test\nvoid evaluateRelevancy() {\n    String question = \"Where does the adventure of Anacletus and Birba take place?\";\n\n    RetrievalAugmentationAdvisor ragAdvisor = RetrievalAugmentationAdvisor.builder()\n        .documentRetriever(VectorStoreDocumentRetriever.builder()\n            .vectorStore(pgVectorStore)\n            .build())\n        .build();\n\n    ChatResponse chatResponse = ChatClient.builder(chatModel).build()\n        .prompt(question)\n        .advisors(ragAdvisor)\n        .call()\n        .chatResponse();\n\n    EvaluationRequest evaluationRequest = new EvaluationRequest(\n        // The original user question\n        question,\n        // The retrieved context from the RAG flow\n        chatResponse.getMetadata().get(RetrievalAugmentationAdvisor.DOCUMENT_CONTEXT),\n        // The AI model's response\n        chatResponse.getResult().getOutput().getText()\n    );\n\n    RelevancyEvaluator evaluator = new RelevancyEvaluator(ChatClient.builder(chatModel));\n\n    EvaluationResponse evaluationResponse = evaluator.evaluate(evaluationRequest);\n\n    assertThat(evaluationResponse.isPass()).isTrue();\n}\n----\n\nYou can find several integration tests in the Spring AI project that use the `RelevancyEvaluator` to test the functionality of the `QuestionAnswerAdvisor` (see https://github.com/spring-projects/spring-ai/blob/main/spring-ai-integration-tests/src/test/java/org/springframework/ai/integration/tests/client/advisor/QuestionAnswerAdvisorIT.java[tests]) and `RetrievalAugmentationAdvisor` (see https://github.com/spring-projects/spring-ai/blob/main/spring-ai-integration-tests/src/test/java/org/springframework/ai/integration/tests/client/advisor/RetrievalAugmentationAdvisorIT.java[tests]).\n\n=== Custom Template\n\nThe `RelevancyEvaluator` uses a default template to prompt the AI model for evaluation. You can customize this behavior by providing your own `PromptTemplate` object via the `.promptTemplate()` builder method.\n\nThe custom `PromptTemplate` can use any `TemplateRenderer` implementation (by default, it uses `StPromptTemplate` based on the https://www.stringtemplate.org/[StringTemplate] engine). The important requirement is that the template must contain the following placeholders:\n\n* a `query` placeholder to receive the user question.\n* a `response` placeholder to receive the AI model's response.\n* a `context` placeholder to receive the context information.\n\n== FactCheckingEvaluator\n\nThe FactCheckingEvaluator is another implementation of the Evaluator interface, designed to assess the factual accuracy of AI-generated responses against provided context. This evaluator helps detect and reduce hallucinations in AI outputs by verifying if a given statement (claim) is logically supported by the provided context (document).\n\nThe 'claim' and 'document' are presented to the AI model for evaluation. Smaller and more efficient AI models dedicated to this purpose are available, such as Bespoke's Minicheck, which helps reduce the cost of performing these checks compared to flagship models like GPT-4. Minicheck is also available for use through Ollama.\n\n\n=== Usage\nThe FactCheckingEvaluator constructor takes a ChatClient.Builder as a parameter:\n[source,java]\n----\npublic FactCheckingEvaluator(ChatClient.Builder chatClientBuilder) {\n  this.chatClientBuilder = chatClientBuilder;\n}\n----\nThe evaluator uses the following prompt template for fact-checking:\n[source,text]\n----\nDocument: {document}\nClaim: {claim}\n----\nWhere `+{document}+` is the context information, and `+{claim}+` is the AI model's response to be evaluated.\n\n=== Example\nHere's an example of how to use the FactCheckingEvaluator with an Ollama-based ChatModel, specifically the Bespoke-Minicheck model:\n\n[source,java]\n----\n@Test\nvoid testFactChecking() {\n  // Set up the Ollama API\n  OllamaApi ollamaApi = new OllamaApi(\"http://localhost:11434\");\n\n  ChatModel chatModel = new OllamaChatModel(ollamaApi,\n\t\t\t\tOllamaChatOptions.builder().model(BESPOKE_MINICHECK).numPredict(2).temperature(0.0d).build())\n\n\n  // Create the FactCheckingEvaluator\n  var factCheckingEvaluator = new FactCheckingEvaluator(ChatClient.builder(chatModel));\n\n  // Example context and claim\n  String context = \"The Earth is the third planet from the Sun and the only astronomical object known to harbor life.\";\n  String claim = \"The Earth is the fourth planet from the Sun.\";\n\n  // Create an EvaluationRequest\n  EvaluationRequest evaluationRequest = new EvaluationRequest(context, Collections.emptyList(), claim);\n\n  // Perform the evaluation\n  EvaluationResponse evaluationResponse = factCheckingEvaluator.evaluate(evaluationRequest);\n\n  assertFalse(evaluationResponse.isPass(), \"The claim should not be supported by the context\");\n\n}\n----\n"

    "content": "= Migrating from FunctionCallback to ToolCallback API\n\nThis guide helps you migrate from the deprecated `FunctionCallback` API to the new `ToolCallback` API in Spring AI. For more information about the new APIs, check out the xref:api/tools.adoc[Tools Calling] documentation.\n\n== Overview of Changes\n\nThese changes are part of a broader effort to improve and extend the tool calling capabilities in Spring AI. Among the other things, the new API moves from \"functions\" to \"tools\" terminology to better align with industry conventions. This involves several API changes while maintaining backward compatibility through deprecated methods.\n\n== Key Changes\n\n1. `FunctionCallback` → `ToolCallback`\n2. `FunctionCallback.builder().function()` → `FunctionToolCallback.builder()`\n3. `FunctionCallback.builder().method()` → `MethodToolCallback.builder()`\n4. `FunctionCallingOptions` → `ToolCallingChatOptions`\n5. `ChatClient.builder().defaultFunctions()` → `ChatClient.builder().defaultTools()`\n6. `ChatClient.functions()` → `ChatClient.tools()`\n7. `FunctionCallingOptions.builder().functions()` → `ToolCallingChatOptions.builder().toolNames()`\n8. `FunctionCallingOptions.builder().functionCallbacks()` → `ToolCallingChatOptions.builder().toolCallbacks()`\n\n== Migration Examples\n\n=== 1. Basic Function Callback\n\nBefore:\n[source,java]\n----\nFunctionCallback.builder()\n    .function(\"getCurrentWeather\", new MockWeatherService())\n    .description(\"Get the weather in location\")\n    .inputType(MockWeatherService.Request.class)\n    .build()\n----\n\nAfter:\n[source,java]\n----\nFunctionToolCallback.builder(\"getCurrentWeather\", new MockWeatherService())\n    .description(\"Get the weather in location\")\n    .inputType(MockWeatherService.Request.class)\n    .build()\n----\n\n=== 2. ChatClient Usage\n\nBefore:\n[source,java]\n----\nString response = ChatClient.create(chatModel)\n    .prompt()\n    .user(\"What's the weather like in San Francisco?\")\n    .functions(FunctionCallback.builder()\n        .function(\"getCurrentWeather\", new MockWeatherService())\n        .description(\"Get the weather in location\")\n        .inputType(MockWeatherService.Request.class)\n        .build())\n    .call()\n    .content();\n----\n\nAfter:\n[source,java]\n----\nString response = ChatClient.create(chatModel)\n    .prompt()\n    .user(\"What's the weather like in San Francisco?\")\n    .tools(FunctionToolCallback.builder(\"getCurrentWeather\", new MockWeatherService())\n        .description(\"Get the weather in location\")\n        .inputType(MockWeatherService.Request.class)\n        .build())\n    .call()\n    .content();\n----\n\n=== 3. Method-Based Function Callbacks\n\nBefore:\n[source,java]\n----\nFunctionCallback.builder()\n    .method(\"getWeatherInLocation\", String.class, Unit.class)\n    .description(\"Get the weather in location\")\n    .targetClass(TestFunctionClass.class)\n    .build()\n----\n\nAfter:\n[source,java]\n----\nvar toolMethod = ReflectionUtils.findMethod(TestFunctionClass.class, \"getWeatherInLocation\");\n\nMethodToolCallback.builder()\n    .toolDefinition(ToolDefinition.builder(toolMethod)\n        .description(\"Get the weather in location\")\n        .build())\n    .toolMethod(toolMethod)\n    .build()\n----\n\nOr with the declarative approach:\n[source,java]\n----\nclass WeatherTools {\n\n    @Tool(description = \"Get the weather in location\")\n    public void getWeatherInLocation(String location, Unit unit) {\n        // ...\n    }\n\n}\n----\n\nAnd you can use the same `ChatClient#tools()` API to register method-based tool callbacks:\n\n[source,java]\n----\nString response = ChatClient.create(chatModel)\n    .prompt()\n    .user(\"What's the weather like in San Francisco?\")\n    .tools(MethodToolCallback.builder()\n        .toolDefinition(ToolDefinition.builder(toolMethod)\n            .description(\"Get the weather in location\")\n            .build())\n        .toolMethod(toolMethod)\n        .build())\n    .call()\n    .content();\n----\n\nOr with the declarative approach:\n\n[source,java]\n----\nString response = ChatClient.create(chatModel)\n    .prompt()\n    .user(\"What's the weather like in San Francisco?\")\n    .tools(new WeatherTools())\n    .call()\n    .content();\n----\n\n=== 4. Options Configuration\n\nBefore:\n[source,java]\n----\nFunctionCallingOptions.builder()\n    .model(modelName)\n    .function(\"weatherFunction\")\n    .build()\n----\n\nAfter:\n[source,java]\n----\nToolCallingChatOptions.builder()\n    .model(modelName)\n    .toolNames(\"weatherFunction\")\n    .build()\n----\n\n=== 5. Default Functions in ChatClient Builder\n\nBefore:\n[source,java]\n----\nChatClient.builder(chatModel)\n    .defaultFunctions(FunctionCallback.builder()\n        .function(\"getCurrentWeather\", new MockWeatherService())\n        .description(\"Get the weather in location\")\n        .inputType(MockWeatherService.Request.class)\n        .build())\n    .build()\n----\n\nAfter:\n[source,java]\n----\nChatClient.builder(chatModel)\n    .defaultTools(FunctionToolCallback.builder(\"getCurrentWeather\", new MockWeatherService())\n        .description(\"Get the weather in location\")\n        .inputType(MockWeatherService.Request.class)\n        .build())\n    .build()\n----\n\n=== 6. Spring Bean Configuration\n\nBefore:\n[source,java]\n----\n@Bean\npublic FunctionCallback weatherFunctionInfo() {\n    return FunctionCallback.builder()\n        .function(\"WeatherInfo\", new MockWeatherService())\n        .description(\"Get the current weather\")\n        .inputType(MockWeatherService.Request.class)\n        .build();\n}\n----\n\nAfter:\n[source,java]\n----\n@Bean\npublic ToolCallback weatherFunctionInfo() {\n    return FunctionToolCallback.builder(\"WeatherInfo\", new MockWeatherService())\n        .description(\"Get the current weather\")\n        .inputType(MockWeatherService.Request.class)\n        .build();\n}\n----\n\n== Breaking Changes\n\n1. The `method()` configuration in function callbacks has been replaced with a more explicit method tool configuration using `ToolDefinition` and `MethodToolCallback`.\n\n2. When using method-based callbacks, you now need to explicitly find the method using `ReflectionUtils` and provide it to the builder. Alternatively, you can use the declarative approach with the `@Tool` annotation.\n\n3. For non-static methods, you must now provide both the method and the target object:\n[source,java]\n----\nMethodToolCallback.builder()\n    .toolDefinition(ToolDefinition.builder(toolMethod)\n        .description(\"Description\")\n        .build())\n    .toolMethod(toolMethod)\n    .toolObject(targetObject)\n    .build()\n----\n\n== Deprecated Methods\n\nThe following methods are deprecated and will be removed in a future release:\n\n- `ChatClient.Builder.defaultFunctions(String...)`\n- `ChatClient.Builder.defaultFunctions(FunctionCallback...)`\n- `ChatClient.RequestSpec.functions()`\n\nUse their `tools` counterparts instead.\n\n== Declarative Specification with @Tool\n\nNow you can use the method-level annotation (`@Tool`) to register tools with Spring AI:\n\n[source,java]\n----\nclass Home {\n\n    @Tool(description = \"Turn light On or Off in a room.\")\n    void turnLight(String roomName, boolean on) {\n        // ...\n        logger.info(\"Turn light in room: {} to: {}\", roomName, on);\n    }\n}\n\nString response = ChatClient.create(this.chatModel).prompt()\n        .user(\"Turn the light in the living room On.\")\n        .tools(new Home())\n        .call()\n        .content();\n----\n\n== Additional Notes\n\n1. The new API provides better separation between tool definition and implementation.\n2. Tool definitions can be reused across different implementations.\n3. The builder pattern has been simplified for common use cases.\n4. Better support for method-based tools with improved error handling.\n\n== Timeline\n\nThe deprecated methods will be maintained for backward compatibility in the current milestone version but will be removed in the next milestone release. It's recommended to migrate to the new API as soon as possible.\n"

    "content": "[[Tools]]\n= Tool Calling\n\n_Tool calling_ (also known as _function calling_) is a common pattern in AI applications allowing a model to interact with a set of APIs, or _tools_, augmenting its capabilities.\n\nTools are mainly used for:\n\n* **Information Retrieval**. Tools in this category can be used to retrieve information from external sources, such as a database, a web service, a file system, or a web search engine. The goal is to augment the knowledge of the model, allowing it to answer questions that it would not be able to answer otherwise. As such, they can be used in Retrieval Augmented Generation (RAG) scenarios. For example, a tool can be used to retrieve the current weather for a given location, to retrieve the latest news articles, or to query a database for a specific record.\n* **Taking Action**. Tools in this category can be used to take action in a software system, such as sending an email, creating a new record in a database, submitting a form, or triggering a workflow. The goal is to automate tasks that would otherwise require human intervention or explicit programming. For example, a tool can be used to book a flight for a customer interacting with a chatbot, to fill out a form on a web page, or to implement a Java class based on an automated test (TDD) in a code generation scenario.\n\nEven though we typically refer to _tool calling_ as a model capability, it is actually up to the client application to provide the tool calling logic. The model can only request a tool call and provide the input arguments, whereas the application is responsible for executing the tool call from the input arguments and returning the result. The model never gets access to any of the APIs provided as tools, which is a critical security consideration.\n\nSpring AI provides convenient APIs to define tools, resolve tool call requests from a model, and execute the tool calls. The following sections provide an overview of the tool calling capabilities in Spring AI.\n\nNOTE: Check the xref:api/chat/comparison.adoc[Chat Model Comparisons] to see which AI models support tool calling invocation.\n\nTIP: Follow the guide to migrate from the deprecated xref:api/tools-migration.adoc[FunctionCallback to ToolCallback API].\n\n== Quick Start\n\nLet's see how to start using tool calling in Spring AI. We'll implement two simple tools: one for information retrieval and one for taking action. The information retrieval tool will be used to get the current date and time in the user's time zone. The action tool will be used to set an alarm for a specified time.\n\n=== Information Retrieval\n\nAI models don't have access to real-time information. Any question that assumes awareness of information such as the current date or weather forecast cannot be answered by the model. However, we can provide a tool that can retrieve this information, and let the model call this tool when access to real-time information is needed.\n\nLet's implement a tool to get the current date and time in the user's time zone in a `DateTimeTools` class. The tool will take no argument. The `LocaleContextHolder` from Spring Framework can provide the user's time zone. The tool will be defined as a method annotated with `@Tool`. To help the model understand if and when to call this tool, we'll provide a detailed description of what the tools does.\n\n[source,java]\n----\nimport java.time.LocalDateTime;\nimport org.springframework.ai.tool.annotation.Tool;\nimport org.springframework.context.i18n.LocaleContextHolder;\n\nclass DateTimeTools {\n\n    @Tool(description = \"Get the current date and time in the user's timezone\")\n    String getCurrentDateTime() {\n        return LocalDateTime.now().atZone(LocaleContextHolder.getTimeZone().toZoneId()).toString();\n    }\n\n}\n----\n\nNext, let's make the tool available to the model. In this example, we'll use the `ChatClient` to interact with the model. We'll provide the tool to the model by passing an instance of `DateTimeTools` via the `tools()` method. When the model needs to know the current date and time, it will request the tool to be called. Internally, the `ChatClient` will call the tool and return the result to the model, which will then use the tool call result to generate the final response to the original question.\n\n[source,java]\n----\nChatModel chatModel = ...\n\nString response = ChatClient.create(chatModel)\n        .prompt(\"What day is tomorrow?\")\n        .tools(new DateTimeTools())\n        .call()\n        .content();\n\nSystem.out.println(response);\n----\n\nThe output will be something like:\n\n[source]\n----\nTomorrow is 2015-10-21.\n----\n\nYou can retry asking the same question again. This time, don't provide the tool to the model. The output will be something like:\n\n[source]\n----\nI am an AI and do not have access to real-time information. Please provide the current date so I can accurately determine what day tomorrow will be.\n----\n\nWithout the tool, the model doesn't know how to answer the question because it doesn't have the ability to determine the current date and time.\n\n=== Taking Actions\n\nAI models can be used to generate plans for accomplishing certain goals. For example, a model can generate a plan for booking a trip to Denmark. However, the model doesn't have the ability to execute the plan. That's where tools come in: they can be used to execute the plan that a model generates.\n\nIn the previous example, we used a tool to determine the current date and time. In this example, we'll define a second tool for setting an alarm at a specific time. The goal is to set an alarm for 10 minutes from now, so we need to provide both tools to the model to accomplish this task.\n\nWe'll add the new tool to the same `DateTimeTools` class as before. The new tool will take a single parameter, which is the time in ISO-8601 format. The tool will then print a message to the console indicating that the alarm has been set for the given time. Like before, the tool is defined as a method annotated with `@Tool`, which we also use to provide a detailed description to help the model understand when and how to use the tool.\n\n[source,java]\n----\nimport java.time.LocalDateTime;\nimport java.time.format.DateTimeFormatter;\nimport org.springframework.ai.tool.annotation.Tool;\nimport org.springframework.context.i18n.LocaleContextHolder;\n\nclass DateTimeTools {\n\n    @Tool(description = \"Get the current date and time in the user's timezone\")\n    String getCurrentDateTime() {\n        return LocalDateTime.now().atZone(LocaleContextHolder.getTimeZone().toZoneId()).toString();\n    }\n\n    @Tool(description = \"Set a user alarm for the given time, provided in ISO-8601 format\")\n    void setAlarm(String time) {\n        LocalDateTime alarmTime = LocalDateTime.parse(time, DateTimeFormatter.ISO_DATE_TIME);\n        System.out.println(\"Alarm set for \" + alarmTime);\n    }\n\n}\n----\n\nNext, let's make both tools available to the model. We'll use the `ChatClient` to interact with the model. We'll provide the tools to the model by passing an instance of `DateTimeTools` via the `tools()` method. When we ask to set up an alarm 10 minutes from now, the model will first need to know the current date and time. Then, it will use the current date and time to calculate the alarm time. Finally, it will use the alarm tool to set up the alarm. Internally, the `ChatClient` will handle any tool call request from the model and send back to it any tool call execution result, so that the model can generate the final response.\n\n[source,java]\n----\nChatModel chatModel = ...\n\nString response = ChatClient.create(chatModel)\n        .prompt(\"Can you set an alarm 10 minutes from now?\")\n        .tools(new DateTimeTools())\n        .call()\n        .content();\n\nSystem.out.println(response);\n----\n\nIn the application logs, you can check the alarm has been set at the correct time.\n\n== Overview\n\nSpring AI supports tool calling through a set of flexible abstractions that allow you to define, resolve, and execute tools in a consistent way. This section provides an overview of the main concepts and components of tool calling in Spring AI.\n\nimage::tools/tool-calling-01.jpg[The main sequence of actions for tool calling, width=700, align=\"center\"]\n\n1. When we want to make a tool available to the model, we include its definition in the chat request. Each tool definition comprises of a name, a description, and the schema of the input parameters.\n2. When the model decides to call a tool, it sends a response with the tool name and the input parameters modeled after the defined schema.\n3. The application is responsible for using the tool name to identify and execute the tool with the provided input parameters.\n4. The result of the tool call is processed by the application.\n5. The application sends the tool call result back to the model.\n6. The model generates the final response using the tool call result as additional context.\n\nTools are the building blocks of tool calling and they are modeled by the `ToolCallback` interface. Spring AI provides built-in support for specifying `ToolCallback`(s) from methods and functions, but you can always define your own `ToolCallback` implementations to support more use cases.\n\n`ChatModel` implementations transparently dispatch tool call requests to the corresponding `ToolCallback` implementations and will send the tool call results back to the model, which will ultimately generate the final response. They do so using the `ToolCallingManager` interface, which is responsible for managing the tool execution lifecycle.\n\nBoth `ChatClient` and `ChatModel` accept a list of `ToolCallback` objects to make the tools available to the model and the `ToolCallingManager` that will eventually execute them. \n\nBesides passing the `ToolCallback` objects directly, you can also pass a list of tool names, that will be resolved dynamically using the `ToolCallbackResolver` interface.\n\nThe following sections will go into more details about all these concepts and APIs, including how to customize and extend them to support more use cases.\n\n== Methods as Tools\n\nSpring AI provides built-in support for specifying tools (i.e. `ToolCallback`(s)) from methods in two ways:\n\n- declaratively, using the `@Tool` annotation\n- programmatically, using the low-level `MethodToolCallback` implementation.\n\n=== Declarative Specification: `@Tool`\n\nYou can turn a method into a tool by annotating it with `@Tool`.\n\n[source,java]\n----\nclass DateTimeTools {\n\n    @Tool(description = \"Get the current date and time in the user's timezone\")\n    String getCurrentDateTime() {\n        return LocalDateTime.now().atZone(LocaleContextHolder.getTimeZone().toZoneId()).toString();\n    }\n\n}\n----\n\nThe `@Tool` annotation allows you to provide key information about the tool:\n\n- `name`: The name of the tool. If not provided, the method name will be used. AI models use this name to identify the tool when calling it. Therefore, it's not allowed to have two tools with the same name in the same class. The name must be unique across all the tools available to the model for a specific chat request.\n- `description`: The description for the tool, which can be used by the model to understand when and how to call the tool. If not provided, the method name will be used as the tool description. However, it's strongly recommended to provide a detailed description because that's paramount for the model to understand the tool's purpose and how to use it. Failing in providing a good description can lead to the model not using the tool when it should or using it incorrectly.\n- `returnDirect`: Whether the tool result should be returned directly to the client or passed back to the model. See xref:_return_direct[] for more details.\n- `resultConverter`: The `ToolCallResultConverter` implementation to use for converting the result of a tool call to a `String object` to send back to the AI model. See xref:_result_conversion[] for more details.\n\nThe method can be either static or instance, and it can have any visibility (public, protected, package-private, or private). The class that contains the method can be either a top-level class or a nested class, and it can also have any visibility (as long as it's accessible where you're planning to instantiate it).\n\nNOTE: Spring AI provides built-in support for AOT compilation of the `@Tool`-annotated methods as long as the class containing the methods is a Spring bean (e.g. `@Component`). Otherwise, you'll need to provide the necessary configuration to the GraalVM compiler. For example, by annotating the class with `@RegisterReflection(memberCategories = MemberCategory.INVOKE_DECLARED_METHODS)`.\n\nYou can define any number of arguments for the method (including no argument) with most types (primitives, POJOs, enums, lists, arrays, maps, and so on). Similarly, the method can return most types, including `void`. If the method returns a value, the return type must be a serializable type, as the result will be serialized and sent back to the model.\n\nNOTE: Some types are not supported. See xref:_method_tool_limitations[] for more details.\n\nSpring AI will generate the JSON schema for the input parameters of the `@Tool`-annotated method automatically. The schema is used by the model to understand how to call the tool and prepare the tool request. The `@ToolParam` annotation can be used to provide additional information about the input parameters, such as a description or whether the parameter is required or optional. By default, all input parameters are considered required.\n\n[source,java]\n----\nimport java.time.LocalDateTime;\nimport java.time.format.DateTimeFormatter;\nimport org.springframework.ai.tool.annotation.Tool;\nimport org.springframework.ai.tool.annotation.ToolParam;\n\nclass DateTimeTools {\n\n    @Tool(description = \"Set a user alarm for the given time\")\n    void setAlarm(@ToolParam(description = \"Time in ISO-8601 format\") String time) {\n        LocalDateTime alarmTime = LocalDateTime.parse(time, DateTimeFormatter.ISO_DATE_TIME);\n        System.out.println(\"Alarm set for \" + alarmTime);\n    }\n\n}\n----\n\nThe `@ToolParam` annotation allows you to provide key information about a tool parameter:\n\n- `description`: The description for the parameter, which can be used by the model to understand better how to use it. For example, what format the parameter should be in, what values are allowed, and so on.\n- `required`: Whether the parameter is required or optional. By default, all parameters are considered required. \n\nIf a parameter is annotated as `@Nullable`, it will be considered optional unless explicitly marked as required using the `@ToolParam` annotation.\n\nBesides the `@ToolParam` annotation, you can also use the `@Schema` annotation from Swagger or `@JsonProperty` from Jackson. See xref:_json_schema[] for more details.\n\n==== Adding Tools to `ChatClient`\n\nWhen using the declarative specification approach, you can pass the tool class instance to the `tools()` method when invoking a `ChatClient`. Such tools will only be available for the specific chat request they are added to.\n\n[source,java]\n----\nChatClient.create(chatModel)\n    .prompt(\"What day is tomorrow?\")\n    .tools(new DateTimeTools())\n    .call()\n    .content();\n----\n\nUnder the hood, the `ChatClient` will generate a `ToolCallback` from each `@Tool`-annotated method in the tool class instance and pass them to the model. In case you prefer to generate the `ToolCallback`(s) yourself, you can use the `ToolCallbacks` utility class.\n\n[source,java]\n----\nToolCallback[] dateTimeTools = ToolCallbacks.from(new DateTimeTools());\n----\n\n==== Adding Default Tools to `ChatClient`\n\nWhen using the declarative specification approach, you can add default tools to a `ChatClient.Builder` by passing the tool class instance to the `defaultTools()` method.\nIf both default and runtime tools are provided, the runtime tools will completely override the default tools.\n\nWARNING: Default tools are shared across all the chat requests performed by all the `ChatClient` instances built from the same `ChatClient.Builder`. They are useful for tools that are commonly used across different chat requests, but they can also be dangerous if not used carefully, risking to make them available when they shouldn't.\n\n[source,java]\n----\nChatModel chatModel = ...\nChatClient chatClient = ChatClient.builder(chatModel)\n    .defaultTools(new DateTimeTools())\n    .build();\n----\n\n==== Adding Tools to `ChatModel`\n\nWhen using the declarative specification approach, you can pass the tool class instance to the `toolCallbacks()` method of the `ToolCallingChatOptions` you use to call a `ChatModel`. Such tools will only be available for the specific chat request they are added to.\n\n[source,java]\n----\nChatModel chatModel = ...\nToolCallback[] dateTimeTools = ToolCallbacks.from(new DateTimeTools());\nChatOptions chatOptions = ToolCallingChatOptions.builder()\n    .toolCallbacks(dateTimeTools)\n    .build();\nPrompt prompt = new Prompt(\"What day is tomorrow?\", chatOptions);\nchatModel.call(prompt);\n----\n\n==== Adding Default Tools to `ChatModel`\n\nWhen using the declarative specification approach, you can add default tools to `ChatModel` at construction time by passing the tool class instance to the `toolCallbacks()` method of the `ToolCallingChatOptions` instance used to create the `ChatModel`.\nIf both default and runtime tools are provided, the runtime tools will completely override the default tools.\n\nWARNING: Default tools are shared across all the chat requests performed by that `ChatModel` instance.

You can build it using the `ToolDefinition.Builder` class. Required.\n- `toolMetadata`: The `ToolMetadata` instance that defines additional settings such as whether the result should be returned directly to the client, and the result converter to use. You can build it using the `ToolMetadata.Builder` class.\n- `toolMethod`: The `Method` instance that represents the tool method. Required.\n- `toolObject`: The object instance that contains the tool method. If the method is static, you can omit this parameter.\n- `toolCallResultConverter`: The `ToolCallResultConverter` instance to use for converting the result of a tool call to a `String` object to send back to the AI model. If not provided, the default converter will be used (`DefaultToolCallResultConverter`).\n\nThe `ToolDefinition.Builder` allows you to build a `ToolDefinition` instance and define the tool name, description, and input schema:\n\n- `name`: The name of the tool. If not provided, the method name will be used. AI models use this name to identify the tool when calling it. Therefore, it's not allowed to have two tools with the same name in the same class. The name must be unique across all the tools available to the model for a specific chat request.\n- `description`: The description for the tool, which can be used by the model to understand when and how to call the tool. If not provided, the method name will be used as the tool description. However, it's strongly recommended to provide a detailed description because that's paramount for the model to understand the tool's purpose and how to use it. Failing in providing a good description can lead to the model not using the tool when it should or using it incorrectly.\n- `inputSchema`: The JSON schema for the input parameters of the tool. If not provided, the schema will be generated automatically based on the method parameters. You can use the `@ToolParam` annotation to provide additional information about the input parameters, such as a description or whether the parameter is required or optional. By default, all input parameters are considered required. See xref:_json_schema[] for more details.\n\nThe `ToolMetadata.Builder` allows you to build a `ToolMetadata` instance and define additional settings for the tool:\n\n- `returnDirect`: Whether the tool result should be returned directly to the client or passed back to the model. See xref:_return_direct[] for more details.\n\n[source,java]\n----\nMethod method = ReflectionUtils.findMethod(DateTimeTools.class, \"getCurrentDateTime\");\nToolCallback toolCallback = MethodToolCallback.builder()\n    .toolDefinition(ToolDefinitions.builder(method)\n            .description(\"Get the current date and time in the user's timezone\")\n            .build())\n    .toolMethod(method)\n    .toolObject(new DateTimeTools())\n    .build();\n----\n\nThe method can be either static or instance, and it can have any visibility (public, protected, package-private, or private). The class that contains the method can be either a top-level class or a nested class, and it can also have any visibility (as long as it's accessible where you're planning to instantiate it).\n\nNOTE: Spring AI provides built-in support for AOT compilation of the tool methods as long as the class containing the methods is a Spring bean (e.g. `@Component`). Otherwise, you'll need to provide the necessary configuration to the GraalVM compiler. For example, by annotating the class with `@RegisterReflection(memberCategories = MemberCategory.INVOKE_DECLARED_METHODS)`.\n\nYou can define any number of arguments for the method (including no argument) with most types (primitives, POJOs, enums, lists, arrays, maps, and so on). Similarly, the method can return most types, including `void`. If the method returns a value, the return type must be a serializable type, as the result will be serialized and sent back to the model.\n\nNOTE: Some types are not supported. See xref:_method_tool_limitations[] for more details.\n\nIf the method is static, you can omit the `toolObject()` method, as it's not needed.\n\n[source,java]\n----\nclass DateTimeTools {\n\n    static String getCurrentDateTime() {\n        return LocalDateTime.now().atZone(LocaleContextHolder.getTimeZone().toZoneId()).toString();\n    }\n\n}\n----\n\n[source,java]\n----\nMethod method = ReflectionUtils.findMethod(DateTimeTools.class, \"getCurrentDateTime\");\nToolCallback toolCallback = MethodToolCallback.builder()\n    .toolDefinition(ToolDefinitions.builder(method)\n            .description(\"Get the current date and time in the user's timezone\")\n            .build())\n    .toolMethod(method)\n    .build();\n----\n\nSpring AI will generate the JSON schema for the input parameters of the method automatically. The schema is used by the model to understand how to call the tool and prepare the tool request.

By default, all input parameters are considered required.\n\n[source,java]\n----\nimport java.time.LocalDateTime;\nimport java.time.format.DateTimeFormatter;\nimport org.springframework.ai.tool.annotation.ToolParam;\n\nclass DateTimeTools {\n\n    void setAlarm(@ToolParam(description = \"Time in ISO-8601 format\") String time) {\n        LocalDateTime alarmTime = LocalDateTime.parse(time, DateTimeFormatter.ISO_DATE_TIME);\n        System.out.println(\"Alarm set for \" + alarmTime);\n    }\n\n}\n----\n\nThe `@ToolParam` annotation allows you to provide key information about a tool parameter:\n\n- `description`: The description for the parameter, which can be used by the model to understand better how to use it. For example, what format the parameter should be in, what values are allowed, and so on.\n- `required`: Whether the parameter is required or optional. By default, all parameters are considered required. \n\nIf a parameter is annotated as `@Nullable`, it will be considered optional unless explicitly marked as required using the `@ToolParam` annotation.\n\nBesides the `@ToolParam` annotation, you can also use the `@Schema` annotation from Swagger or `@JsonProperty` from Jackson.

If not provided, the method name will be used as the tool description. However, it's strongly recommended to provide a detailed description because that's paramount for the model to understand the tool's purpose and how to use it.

This option gives you the possibility to use any `Function`, `Supplier`, `Consumer`, or `BiFunction` bean as a tool. The bean name will be used as the tool name, and the `@Description` annotation from Spring Framework can be used to provide a description for the tool, used by the model to understand when and how to call the tool. If you don't provide a description, the method name will be used as the tool description. However, it's strongly recommended to provide a detailed description because that's paramount for the model to understand the tool's purpose and how to use it.

See xref:_methods_as_tools[] for more details.\n\n== Tool Specification\n\nIn Spring AI, tools are modeled via the `ToolCallback` interface. In the previous sections, we've seen how to define tools from methods and functions using the built-in support provided by Spring AI (see xref:_methods_as_tools[] and xref:_functions_as_tools[]). This section will dive deeper into the tool specification and how to customize and extend it to support more use cases.\n\n=== Tool Callback\n\nThe `ToolCallback` interface provides a way to define a tool that can be called by the AI model, including both definition and execution logic. It's the main interface to implement when you want to define a tool from scratch. For example, you can define a `ToolCallback` from an MCP Client (using the Model Context Protocol) or a `ChatClient` (to build a modular agentic application).\n\nThe interface provides the following methods:\n\n[source,java]\n----\npublic interface ToolCallback {\n\n\t/**\n\t * Definition used by the AI model to determine when and how to call the tool.\n\t */\n\tToolDefinition getToolDefinition();\n\n\t/**\n\t * Metadata providing additional information on how to handle the tool.\n\t */\n\tToolMetadata getToolMetadata();\n\n    /**\n\t * Execute tool with the given input and return the result to send back to the AI model.\n\t */\n\tString call(String toolInput);\n\n    /**\n\t * Execute tool with the given input and context, and return the result to send back to the AI model.\n\t */\n\tString call(String toolInput, ToolContext tooContext);\n\n}\n----\n\nSpring AI provides built-in implementations for tool methods (`MethodToolCallback`) and tool functions (`FunctionToolCallback`).\n\n=== Tool Definition\n\nThe `ToolDefinition` interface provides the required information for the AI model to know about the availability of the tool, including the tool name, description, and input schema. Each `ToolCallback` implementation must provide a `ToolDefinition` instance to define the tool.\n\nThe interface provides the following methods:\n\n[source,java]\n----\npublic interface ToolDefinition {\n\n\t/**\n\t * The tool name. Unique within the tool set provided to a model.\n\t */\n\tString name();\n\n\t/**\n\t * The tool description, used by the AI model to determine what the tool does.\n\t */\n\tString description();\n\n\t/**\n\t * The schema of the parameters used to call the tool.\n\t */\n\tString inputSchema();\n\n}\n----\n\nNOTE: See xref:_json_schema[] for more details on the input schema.\n\nThe `ToolDefinition.Builder` lets you build a `ToolDefinition` instance using the default implementation (`DefaultToolDefinition`).\n\n[source,java]\n----\nToolDefinition toolDefinition = ToolDefinition.builder()\n    .name(\"currentWeather\")\n    .description(\"Get the weather in location\")\n    .inputSchema(\"\"\"\n        {\n            \"type\": \"object\",\n            \"properties\": {\n                \"location\": {\n                    \"type\": \"string\"\n                },\n                \"unit\": {\n                    \"type\": \"string\",\n                    \"enum\": [\"C\", \"F\"]\n                }\n            },\n            \"required\": [\"location\", \"unit\"]\n        }\n    \"\"\")\n    .build();\n----\n\n==== Method Tool Definition\n\nWhen building tools from a method, the `ToolDefinition` is automatically generated for you. In case you prefer to generate the `ToolDefinition` yourself, you can use this convenient builder.\n\n[source,java]\n----\nMethod method = ReflectionUtils.findMethod(DateTimeTools.class, \"getCurrentDateTime\");\nToolDefinition toolDefinition = ToolDefinitions.from(method);\n----\n\nThe `ToolDefinition` generated from a method includes the method name as the tool name, the method name as the tool description, and the JSON schema of the method input parameters. If the method is annotated with `@Tool`, the tool name and description will be taken from the annotation, if set.\n\nNOTE: See xref:_methods_as_tools[] for more details.\n\nIf you'd rather provide some or all of the attributes explicitly, you can use the `ToolDefinition.Builder` to build a custom `ToolDefinition` instance.\n\n[source,java]\n----\nMethod method = ReflectionUtils.findMethod(DateTimeTools.class, \"getCurrentDateTime\");\nToolDefinition toolDefinition = ToolDefinitions.builder(method)\n    .name(\"currentDateTime\")\n    .description(\"Get the current date and time in the user's timezone\")\n    .inputSchema(JsonSchemaGenerator.generateForMethodInput(method))\n    .build();\n----\n\n==== Function Tool Definition\n\nWhen building tools from a function, the `ToolDefinition` is automatically generated for you. When you use the `FunctionToolCallback.Builder` to build a `FunctionToolCallback` instance, you can provide the tool name, description, and input schema that will be used to generate the `ToolDefinition`. See xref:_functions_as_tools[] for more details.\n\n=== JSON Schema\n\nWhen providing a tool to the AI model, the model needs to know the schema of the input type for calling the tool. The schema is used to understand how to call the tool and prepare the tool request. Spring AI provides built-in support for generating the JSON Schema of the input type for a tool via the `JsonSchemaGenerator` class. The schema is provided as part of the `ToolDefinition`.\n\nNOTE: See xref:_tool_definition[] for more details on the `ToolDefinition` and how to pass the input schema to it.\n\nThe `JsonSchemaGenerator` class is used under the hood to generate the JSON schema for the input parameters of a method or a function, using any of the strategies described in xref:_methods_as_tools[] and xref:_functions_as_tools[]. The JSON schema generation logic supports a series of annotations that you can use on the input parameters for methods and functions to customize the resulting schema.\n\nThis section describes two main options you can customize when generating the JSON schema for the input parameters of a tool: description and required status.\n\n==== Description\n\nBesides providing a description for the tool itself, you can also provide a description for the input parameters of a tool. The description can be used to provide key information about the input parameters, such as what format the parameter should be in, what values are allowed, and so on. This is useful to help the model understand the input schema and how to use it. Spring AI provides built-in support for generating the description for an input parameter using one of the following annotations:\n\n- `@ToolParam(description = \"...\")` from Spring AI\n- `@JsonClassDescription(description = \"...\")` from Jackson\n- `@JsonPropertyDescription(description = \"...\")` from Jackson\n- `@Schema(description = \"...\")` from Swagger.\n\nThis approach works for both methods and functions, and you can use it recursively for nested types.\n\n[source,java]\n----\nimport java.time.LocalDateTime;\nimport java.time.format.DateTimeFormatter;\nimport org.springframework.ai.tool.annotation.Tool;\nimport org.springframework.ai.tool.annotation.ToolParam;\nimport org.springframework.context.i18n.LocaleContextHolder;\n\nclass DateTimeTools {\n\n    @Tool(description = \"Set a user alarm for the given time\")\n    void setAlarm(@ToolParam(description = \"Time in ISO-8601 format\") String time) {\n        LocalDateTime alarmTime = LocalDateTime.parse(time, DateTimeFormatter.ISO_DATE_TIME);\n        System.out.println(\"Alarm set for \" + alarmTime);\n    }\n\n}\n----\n\n==== Required/Optional\n\nBy default, each input parameter is considered required, which forces the AI model to provide a value for it when calling the tool. However, you can make an input parameter optional by using one of the following annotations, in this order of precedence:\n\n- `@ToolParam(required = false)` from Spring AI\n- `@JsonProperty(required = false)` from Jackson\n- `@Schema(required = false)` from Swagger\n- `@Nullable` from Spring Framework.\n\nThis approach works for both methods and functions, and you can use it recursively for nested types.\n\n[source,java]\n----\nclass CustomerTools {\n\n    @Tool(description = \"Update customer information\")\n    void updateCustomerInfo(Long id, String name, @ToolParam(required = false) String email) {\n        System.out.println(\"Updated info for customer with id: \" + id);\n    }\n\n}\n----\n\nWARNING: Defining the correct required status for the input parameter is crucial to mitigate the risk of hallucinations and ensure the model provides the right input when calling the tool. In the previous example, the `email` parameter is optional, which means the model can call the tool without providing a value for it. If the parameter was required, the model would have to provide a value for it when calling the tool. And if no value existed, the model would probably make one up, leading to hallucinations.\n\n=== Result Conversion\n\nThe result of a tool call is serialized using a `ToolCallResultConverter` and then sent back to the AI model. The `ToolCallResultConverter` interface provides a way to convert the result of a tool call to a `String` object.\n\nThe interface provides the following method:\n\n[source,java]\n----\n@FunctionalInterface\npublic interface ToolCallResultConverter {\n\n\t/**\n\t * Given an Object returned by a tool, convert it to a String compatible with the\n\t * given class type.\n\t */\n\tString convert(@Nullable Object result, @Nullable Type returnType);\n\n}\n----\n\nThe result must be a serializable type. By default, the result is serialized to JSON using Jackson (`DefaultToolCallResultConverter`), but you can customize the serialization process by providing your own `ToolCallResultConverter` implementation.\n\nSpring AI relies on the `ToolCallResultConverter` in both method and function tools.\n\n==== Method Tool Call Result Conversion\n\nWhen building tools from a method with the declarative approach, you can provide a custom `ToolCallResultConverter` to use for the tool by setting the `resultConverter()` attribute of the `@Tool` annotation.\n\n[source,java]\n----\nclass CustomerTools {\n\n    @Tool(description = \"Retrieve customer information\", resultConverter = CustomToolCallResultConverter.class)\n    Customer getCustomerInfo(Long id) {\n        return customerRepository.findById(id);\n    }\n\n}\n----\n\nIf using the programmatic approach, you can provide a custom `ToolCallResultConverter` to use for the tool by setting the `resultConverter()` attribute of the `MethodToolCallback.Builder`.\n\nSee xref:_methods_as_tools[] for more details.\n\n==== Function Tool Call Result Conversion\n\nWhen building tools from a function using the programmatic approach, you can provide a custom `ToolCallResultConverter` to use for the tool by setting the `resultConverter()` attribute of the `FunctionToolCallback.Builder`.\n\nSee xref:_functions_as_tools[] for more details.\n\n=== Tool Context\n\nSpring AI supports passing additional contextual information to tools through the `ToolContext` API. This feature allows you to provide extra, user-provided data that can be used within the tool execution along with the tool arguments passed by the AI model. \n\nimage::tools/tool-context.jpg[Providing additional contextual info to tools, width=700, align=\"center\"]\n\n[source,java]\n----\nclass CustomerTools {\n\n    @Tool(description = \"Retrieve customer information\")\n    Customer getCustomerInfo(Long id, ToolContext toolContext) {\n        return customerRepository.findById(id, toolContext.getContext().get(\"tenantId\"));\n    }\n\n}\n----\n\nThe `ToolContext` is populated with the data provided by the user when invoking `ChatClient`.\n\n[source,java]\n----\nChatModel chatModel = ...\n\nString response = ChatClient.create(chatModel)\n        .prompt(\"Tell me more about the customer with ID 42\")\n        .tools(new CustomerTools())\n        .toolContext(Map.of(\"tenantId\", \"acme\"))\n        .call()\n        .content();\n\nSystem.out.println(response);\n----\n\nNOTE: None of the data provided in the `ToolContext` is sent to the AI model.\n\nSimilarly, you can define tool context data when invoking the `ChatModel` directly.\n\n[source,java]\n----\nChatModel chatModel = ...\nToolCallback[] customerTools = ToolCallbacks.from(new CustomerTools());\nChatOptions chatOptions = ToolCallingChatOptions.builder()\n    .toolCallbacks(customerTools)\n    .toolContext(Map.of(\"tenantId\", \"acme\"))\n    .build();\nPrompt prompt = new Prompt(\"Tell me more about the customer with ID 42\", chatOptions);\nchatModel.call(prompt);\n----\n\nIf the `toolContext` option is set both in the default options and in the runtime options, the resulting `ToolContext` will be the merge of the two,\nwhere the runtime options take precedence over the default options.\n\n=== Return Direct\n\nBy default, the result of a tool call is sent back to the model as a response. Then, the model can use the result to continue the conversation.\n\nThere are cases where you'd rather return the result directly to the caller instead of sending it back to the model. For example, if you build an agent that relies on a RAG tool, you might want to return the result directly to the caller instead of sending it back to the model for unnecessary post-processing. Or perhaps you have certain tools that should end the reasoning loop of the agent.\n\nEach `ToolCallback` implementation can define whether the result of a tool call should be returned directly to the caller or sent back to the model. By default, the result is sent back to the model. But you can change this behavior per tool.\n\nThe `ToolCallingManager`, responsible for managing the tool execution lifecycle, is in charge of handling the `returnDirect` attribute associated with the tool. If the attribute is set to `true`, the result of the tool call is returned directly to the caller. Otherwise, the result is sent back to the model.\n\nNOTE: If multiple tool calls are requested at once, the `returnDirect` attribute must be set to `true` for all the tools to return the results directly to the caller. Otherwise, the results will be sent back to the model.\n\nimage::tools/return-direct.jpg[Returning tool call results directly to the caller, width=700, align=\"center\"]\n\n1. When we want to make a tool available to the model, we include its definition in the chat request. If we want the result of the tool execution to be returned directly to the caller, we set the `returnDirect` attribute to `true`.\n2. When the model decides to call a tool, it sends a response with the tool name and the input parameters modeled after the defined schema.\n3. The application is responsible for using the tool name to identify and execute the tool with the provided input parameters.\n4. The result of the tool call is processed by the application.\n5. The application sends the tool call result directly to the caller, instead of sending it back to the model.\n\n==== Method Return Direct\n\nWhen building tools from a method with the declarative approach, you can mark a tool to return the result directly to the caller by setting the `returnDirect` attribute of the `@Tool` annotation to `true`.\n\n[source,java]\n----\nclass CustomerTools {\n\n    @Tool(description = \"Retrieve customer information\", returnDirect = true)\n    Customer getCustomerInfo(Long id) {\n        return customerRepository.findById(id);\n    }\n\n}\n----\n\nIf using the programmatic approach, you can set the `returnDirect` attribute via the `ToolMetadata` interface and pass it to the `MethodToolCallback.Builder`.\n\n[source,java]\n----\nToolMetadata toolMetadata = ToolMetadata.builder()\n    .returnDirect(true)\n    .build();\n----\n\nSee xref:_methods_as_tools[] for more details.\n\n==== Function Return Direct\n\nWhen building tools from a function with the programmatic approach, you can set the `returnDirect` attribute via the `ToolMetadata` interface and pass it to the `FunctionToolCallback.Builder`.\n\n[source,java]\n----\nToolMetadata toolMetadata = ToolMetadata.builder()\n    .returnDirect(true)\n    .build();\n----\n\nSee xref:_functions_as_tools[] for more details.\n\n== Tool Execution\n\nThe tool execution is the process of calling the tool with the provided input arguments and returning the result. The tool execution is handled by the `ToolCallingManager` interface, which is responsible for managing the tool execution lifecycle.\n\n[source,java]\n----\npublic interface ToolCallingManager {\n\n\t/**\n\t * Resolve the tool definitions from the model's tool calling options.\n\t */\n\tList<ToolDefinition> resolveToolDefinitions(ToolCallingChatOptions chatOptions);\n\n\t/**\n\t * Execute the tool calls requested by the model.\n\t */\n\tToolExecutionResult executeToolCalls(Prompt prompt, ChatResponse chatResponse);\n\n}\n----\n\nIf you're using any of the Spring AI Spring Boot Starters, `DefaultToolCallingManager` is the autoconfigured implementation of the `ToolCallingManager` interface. You can customize the tool execution behavior by providing your own `ToolCallingManager` bean.\n\n[source,java]\n----\n@Bean\nToolCallingManager toolCallingManager() {\n    return ToolCallingManager.builder().build();\n}\n----\n\nBy default, Spring AI manages the tool execution lifecycle transparently for you from within each `ChatModel` implementation. But you have the possibility to opt-out of this behavior and control the tool execution yourself. This section describes these two scenarios.\n\n=== Framework-Controlled Tool Execution\n\nWhen using the default behavior, Spring AI will automatically intercept any tool call request from the model, call the tool and return the result to the model. All of this is done transparently for you by each `ChatModel` implementation using a `ToolCallingManager`.\n\nimage::tools/framework-manager.jpg[Framework-controlled tool execution lifecycle, width=700, align=\"center\"]\n\n1. When we want to make a tool available to the model, we include its definition in the chat request (`Prompt`) and invoke the `ChatModel` API which sends the request to the AI model.\n2. When the model decides to call a tool, it sends a response (`ChatResponse`) with the tool name and the input parameters modeled after the defined schema.\n3. The `ChatModel` sends the tool call request to the `ToolCallingManager` API.\n4. The `ToolCallingManager` is responsible for identifying the tool to call and executing it with the provided input parameters.\n5. The result of the tool call is returned to the `ToolCallingManager`.\n6. The `ToolCallingManager` returns the tool execution result back to the `ChatModel`.\n7. The `ChatModel` sends the tool execution result back to the AI model (`ToolResponseMessage`).\n8. The AI model generates the final response using the tool call result as additional context and sends it back to the caller (`ChatResponse`) via the `ChatClient`.\n\nWARNING: Currently, the internal messages exchanged with the model regarding the tool execution are not exposed to the user. If you need to access these messages, you should use the user-controlled tool execution approach.\n\nThe logic determining whether a tool call is eligible for execution is handled by the `ToolExecutionEligibilityPredicate` interface. By default, the tool execution eligibility is determined by checking if the `internalToolExecutionEnabled` attribute of `ToolCallingChatOptions` is set to `true` (the default value), and if the `ChatResponse` contains any tool calls.\n\n[source,java]\n----\npublic class DefaultToolExecutionEligibilityPredicate implements ToolExecutionEligibilityPredicate {\n\n\t@Override\n\tpublic boolean test(ChatOptions promptOptions, ChatResponse chatResponse) {\n\t\treturn ToolCallingChatOptions.isInternalToolExecutionEnabled(promptOptions) && chatResponse != null\n\t\t\t\t&& chatResponse.hasToolCalls();\n\t}\n\n}\n----\n\nYou can provide your custom implementation of `ToolExecutionEligibilityPredicate` when creating the `ChatModel` bean.\n\n=== Advisor-Controlled Tool Execution with ToolCallAdvisor\n\nAs an alternative to the framework-controlled tool execution, you can use the `ToolCallAdvisor` to implement tool calling as part of the xref:api/chatclient.adoc#_advisors[advisor chain]. This approach provides several advantages:\n\n* **Observability**: Other advisors in the chain can intercept and observe each tool call iteration\n* **Integration with Chat Memory**: Works seamlessly with Chat Memory advisors for conversation history management\n* **Extensibility**: The advisor can be extended to customize the tool calling behavior\n\nThe `ToolCallAdvisor` implements the tool calling loop and disables the model's internal tool execution. When the model requests a tool call, the advisor executes the tool and sends the result back to the model, continuing until no more tool calls are needed.\n\n[source,java]\n----\nvar toolCallAdvisor = ToolCallAdvisor.builder()\n    .toolCallingManager(toolCallingManager)\n    .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 300)\n    .build();\n\nvar chatClient = ChatClient.builder(chatModel)\n    .defaultAdvisors(toolCallAdvisor)\n    .build();\n\nString response = chatClient.prompt(\"What day is tomorrow?\")\n    .tools(new DateTimeTools())\n    .call()\n    .content();\n----\n\n==== Configuration Options\n\nThe `ToolCallAdvisor.Builder` supports the following configuration options:\n\n- `toolCallingManager`: The `ToolCallingManager` instance to use for executing tool calls. If not provided, a default instance is used.\n- `advisorOrder`: The order in which the advisor is applied in the chain. Must be between `BaseAdvisor.HIGHEST_PRECEDENCE` and `BaseAdvisor.LOWEST_PRECEDENCE`.\n- `conversationHistoryEnabled`: Controls whether the advisor maintains conversation history internally during tool call iterations. Default is `true`.\n\n==== Conversation History Management\n\nBy default (`conversationHistoryEnabled=true`), the `ToolCallAdvisor` maintains the full conversation history internally during tool call iterations. Each subsequent LLM call includes all previous messages.\n\nUse the `.disableInternalConversationHistory()` method to disable internal conversation history management. When disabled, only the last tool response message is passed to the next iteration. This is useful when integrating with a Chat Memory advisor that already manages conversation history:\n\n[source,java]\n----\nvar toolCallAdvisor = ToolCallAdvisor.builder()\n    .toolCallingManager(toolCallingManager)\n    .disableInternalConversationHistory()  // Let ChatMemory handle history\n    .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 300)\n    .build();\n\nvar chatMemoryAdvisor = MessageChatMemoryAdvisor.builder(chatMemory)\n    .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 200)  // Before ToolCallAdvisor\n    .build();\n\nvar chatClient = ChatClient.builder(chatModel)\n    .defaultAdvisors(chatMemoryAdvisor, toolCallAdvisor)\n    .build();\n----\n\n==== Return Direct\n\nThe `ToolCallAdvisor` supports the \"return direct\" feature, allowing tools to bypass the LLM and return results directly to the client. When a tool execution has `returnDirect=true`, the advisor breaks out of the tool calling loop and returns the tool result directly.\n\nFor more details about `ToolCallAdvisor`, see xref:api/advisors-recursive.adoc#_toolcalladvisor[Recursive Advisors - ToolCallAdvisor].\n\n=== User-Controlled Tool Execution\n\nThere are cases where you'd rather control the tool execution lifecycle yourself. You can do so by setting the `internalToolExecutionEnabled` attribute of `ToolCallingChatOptions` to `false`.\n\nWhen you invoke a `ChatModel` with this option, the tool execution will be delegated to the caller, giving you full control over the tool execution lifecycle. It's your responsibility checking for tool calls in the `ChatResponse` and executing them using the `ToolCallingManager`.\n\nThe following example demonstrates a minimal implementation of the user-controlled tool execution approach:\n\n[source,java]\n----\nChatModel chatModel = ...\nToolCallingManager toolCallingManager = ToolCallingManager.builder().build();\n\nChatOptions chatOptions = ToolCallingChatOptions.builder()\n    .toolCallbacks(new CustomerTools())\n    .internalToolExecutionEnabled(false)\n    .build();\nPrompt prompt = new Prompt(\"Tell me more about the customer with ID 42\", chatOptions);\n\nChatResponse chatResponse = chatModel.call(prompt);\n\nwhile (chatResponse.hasToolCalls()) {\n    ToolExecutionResult toolExecutionResult = toolCallingManager.executeToolCalls(prompt, chatResponse);\n\n    prompt = new Prompt(toolExecutionResult.conversationHistory(), chatOptions);\n\n    chatResponse = chatModel.call(prompt);\n}\n\nSystem.out.println(chatResponse.getResult().getOutput().getText());\n----\n\nNOTE: When choosing the user-controlled tool execution approach, we recommend using a `ToolCallingManager` to manage the tool calling operations. This way, you can benefit from the built-in support provided by Spring AI for tool execution. However, nothing prevents you from implementing your own tool execution logic.\n\nThe next examples shows a minimal implementation of the user-controlled tool execution approach combined with the usage of the `ChatMemory` API:\n\n[source,java]\n----\nToolCallingManager toolCallingManager = DefaultToolCallingManager.builder().build();\nChatMemory chatMemory = MessageWindowChatMemory.builder().build();\nString conversationId = UUID.randomUUID().toString();\n\nChatOptions chatOptions = ToolCallingChatOptions.builder()\n    .toolCallbacks(ToolCallbacks.from(new MathTools()))\n    .internalToolExecutionEnabled(false)\n    .build();\nPrompt prompt = new Prompt(\n        List.of(new SystemMessage(\"You are a helpful assistant.\"), new UserMessage(\"What is 6 * 8?\")),\n        chatOptions);\nchatMemory.add(conversationId, prompt.getInstructions());\n\nPrompt promptWithMemory = new Prompt(chatMemory.get(conversationId), chatOptions);\nChatResponse chatResponse = chatModel.call(promptWithMemory);\nchatMemory.add(conversationId, chatResponse.getResult().getOutput());\n\nwhile (chatResponse.hasToolCalls()) {\n    ToolExecutionResult toolExecutionResult = toolCallingManager.executeToolCalls(promptWithMemory,\n            chatResponse);\n    chatMemory.add(conversationId, toolExecutionResult.conversationHistory()\n        .get(toolExecutionResult.conversationHistory().size() - 1));\n    promptWithMemory = new Prompt(chatMemory.get(conversationId), chatOptions);\n    chatResponse = chatModel.call(promptWithMemory);\n    chatMemory.add(conversationId, chatResponse.getResult().getOutput());\n}\n\nUserMessage newUserMessage = new UserMessage(\"What did I ask you earlier?\");\nchatMemory.add(conversationId, newUserMessage);\n\nChatResponse newResponse = chatModel.call(new Prompt(chatMemory.get(conversationId)));\n----\n\n=== Exception Handling\n\nWhen a tool call fails, the exception is propagated as a `ToolExecutionException` which can be caught to handle the error. \nA `ToolExecutionExceptionProcessor` can be used to handle a `ToolExecutionException` with two outcomes: either producing an error message to be sent back to the AI model or throwing an exception to be handled by the caller.\n\n[source,java]\n----\n@FunctionalInterface\npublic interface ToolExecutionExceptionProcessor {\n\n\t/**\n\t * Convert an exception thrown by a tool to a String that can be sent back to the AI\n\t * model or throw an exception to be handled by the caller.\n\t */\n\tString process(ToolExecutionException exception);\n\n}\n----\n\nIf you're using any of the Spring AI Spring Boot Starters, `DefaultToolExecutionExceptionProcessor` is the autoconfigured implementation of the `ToolExecutionExceptionProcessor` interface. By default, the error message of `RuntimeException` is sent back to the model, while checked exceptions and Errors (e.g., `IOException`, `OutOfMemoryError`) are always thrown. The `DefaultToolExecutionExceptionProcessor` constructor lets you set the `alwaysThrow` attribute to `true` or `false`. If `true`, an exception will be thrown instead of sending an error message back to the model.\n\nYou can use the ``spring.ai.tools.throw-exception-on-error` property to control the behavior of the `DefaultToolExecutionExceptionProcessor` bean:\n\n[cols=\"6,3,1\", stripes=even]\n|====\n| Property | Description | Default\n\n| `spring.ai.tools.throw-exception-on-error` | If `true`, tool calling errors are thrown as exceptions for the caller to handle. If `false`, errors are converted to messages and sent back to the AI model, allowing it to process and respond to the error.| `false`\n|====\n\n\n[source,java]\n----\n@Bean\nToolExecutionExceptionProcessor toolExecutionExceptionProcessor() {\n    return new DefaultToolExecutionExceptionProcessor(true);\n}\n----\n\nNOTE: If you defined your own `ToolCallback` implementation, make sure to throw a `ToolExecutionException` when an error occurs as part of the tool execution logic in the `call()` method.\n\nThe `ToolExecutionExceptionProcessor` is used internally by the default `ToolCallingManager` (`DefaultToolCallingManager`) to handle exceptions during tool execution. See xref:_tool_execution[] for more details about the tool execution lifecycle.\n\n== Tool Resolution\n\nThe main approach for passing tools to a model is by providing the `ToolCallback`(s) when invoking the `ChatClient` or the `ChatModel`,\nusing one of the strategies described in xref:_methods_as_tools[] and xref:_functions_as_tools[].\n\nHowever, Spring AI also supports resolving tools dynamically at runtime using the `ToolCallbackResolver` interface. \n\n[source,java]\n----\npublic interface ToolCallbackResolver {\n\n\t/**\n\t * Resolve the {@link ToolCallback} for the given tool name.\n\t */\n\t@Nullable\n\tToolCallback resolve(String toolName);\n\n}\n----\n\nWhen using this approach:\n\n- On the client-side, you provide the tool names to the `ChatClient` or the `ChatModel` instead of the `ToolCallback`(s).\n- On the server-side, a `ToolCallbackResolver` implementation is responsible for resolving the tool names to the corresponding `ToolCallback` instances.\n\nBy default, Spring AI relies on a `DelegatingToolCallbackResolver` that delegates the tool resolution to a list of `ToolCallbackResolver` instances:\n\n- The `SpringBeanToolCallbackResolver` resolves tools from Spring beans of type `Function`, `Supplier`, `Consumer`, or `BiFunction`. See xref:_dynamic_specification_bean[] for more details.\n- The `StaticToolCallbackResolver` resolves tools from a static list of `ToolCallback` instances. When using the Spring Boot Autoconfiguration, this resolver is automatically configured with all the beans of type `ToolCallback` defined in the application context.\n\nIf you rely on the Spring Boot Autoconfiguration, you can customize the resolution logic by providing a custom `ToolCallbackResolver` bean.\n\n[source,java]\n----\n@Bean\nToolCallbackResolver toolCallbackResolver(List<FunctionCallback> toolCallbacks) {\n    StaticToolCallbackResolver staticToolCallbackResolver = new StaticToolCallbackResolver(toolCallbacks);\n    return new DelegatingToolCallbackResolver(List.of(staticToolCallbackResolver));\n}\n----\n\nThe `ToolCallbackResolver` is used internally by the `ToolCallingManager` to resolve tools dynamically at runtime, supporting both xref:_framework_controlled_tool_execution[] and xref:_user_controlled_tool_execution[].\n\n[[tool-argument-augmentation]]\n== Tool Argument Augmentation\n\nSpring AI provides a utility for **dynamic augmentation of tool input schemas** with additional arguments. This allows capturing extra information from the model—such as reasoning or metadata—without modifying the underlying tool implementation.\n\nCommon use cases include:\n\n* **Inner Thinking/Reasoning**: Capture the model's step-by-step reasoning before executing a tool\n* **Memory Enhancement**: Extract insights to store in long-term memory\n* **Analytics & Tracking**: Collect metadata, user intent, or usage patterns\n* **Multi-Agent Coordination**: Pass agent identifiers or coordination signals\n\n=== Quick Start\n\n**Define augmented arguments** as a Java Record:\n\n[source,java]\n----\npublic record AgentThinking(\n    @ToolParam(description = \"Your reasoning for calling this tool\", required = true)\n    String innerThought,\n\n    @ToolParam(description = \"Confidence level (low, medium, high)\", required = false)\n    String confidence\n) {}\n----\n\n**Wrap your tool** with `AugmentedToolCallbackProvider`:\n\n[source,java]\n----\nAugmentedToolCallbackProvider<AgentThinking> provider = AugmentedToolCallbackProvider\n    .<AgentThinking>builder()\n    .toolObject(new MyTools())  // Your @Tool annotated class\n    .argumentType(AgentThinking.class)\n    .argumentConsumer(event -> {\n        AgentThinking thinking = event.arguments();\n        log.info(\"Tool: {} | Reasoning: {}\", event.toolDefinition().name(), thinking.innerThought());\n    })\n    .removeExtraArgumentsAfterProcessing(true)\n    .build();\n----\n\n**Use with ChatClient**:\n\n[source,java]\n----\nChatClient chatClient = ChatClient.builder(chatModel)\n    .defaultToolCallbacks(provider)\n    .build();\n----\n\nThe LLM sees the augmented schema with your additional fields. Your consumer receives the `AgentThinking` record, while the original tool receives only its expected arguments.\n\n=== Core Components\n\n* `AugmentedToolCallbackProvider<T>` - Wraps tool objects or providers, augmenting all tools with the specified Record type\n* `AugmentedToolCallback<T>` - Wraps individual `ToolCallback` instances\n* `AugmentedArgumentEvent<T>` - Contains `toolDefinition()`, `rawInput()`, and `arguments()` for consumers\n* `ToolInputSchemaAugmenter` - Low-level utility for schema manipulation\n\n=== Configuration\n\nThe `removeExtraArgumentsAfterProcessing` option controls whether augmented arguments are passed to the original tool:\n\n* `true` (default) - Remove augmented arguments before calling the tool\n* `false` - Preserve augmented arguments in the input (if the tool can ignore extra fields)\n\n== Observability\n\nTool calling includes observability support with spring.ai.tool observations that measure completion time and propagate tracing information. See xref:observability/index.adoc#_tool_calling[Tool Calling Observability].\n\nOptionally, Spring AI can export tool call arguments and results as span attributes, disabled by default for sensitivity reasons. Details: xref:observability/index.adoc#_tool_call_arguments_and_result_data[Tool Call Arguments and Result Data].\n\n=== Logging\n\nAll the main operations of the tool calling features are logged at the `DEBUG` level. You can enable the logging by setting the log level to `DEBUG` for the `org.springframework.ai` package.\n"

org.springframework.ai.openai.api.OpenAiApi.Usage) {\n            org.springframework.ai.openai.api.OpenAiApi.Usage nativeUsage =\n                (org.springframework.ai.openai.api.OpenAiApi.Usage) usage.getNativeUsage();\n\n            // Detailed prompt token information\n            System.out.println(\"Prompt Tokens Details:\");\n            System.out.println(\"- Audio Tokens: \" + nativeUsage.promptTokensDetails().audioTokens());\n            System.out.println(\"- Cached Tokens: \" + nativeUsage.promptTokensDetails().cachedTokens());\n\n            // Detailed completion token information\n            System.out.println(\"Completion Tokens Details:\");\n            System.out.println(\"- Reasoning Tokens: \" + nativeUsage.completionTokenDetails().reasoningTokens());\n            System.out.println(\"- Accepted Prediction Tokens: \" + nativeUsage.completionTokenDetails().acceptedPredictionTokens());\n            System.out.println(\"- Audio Tokens: \" + nativeUsage.completionTokenDetails().audioTokens());\n            System.out.println(\"- Rejected Prediction Tokens: \" + nativeUsage.completionTokenDetails().rejectedPredictionTokens());\n        }\n    }\n}\n```\n\n=== Using with ChatClient\n\nIf you are using the `ChatClient`, you can access the usage information using the `ChatResponse` object:\n\n```java\n// Create a chat prompt\nPrompt prompt = new Prompt(\"What is the weather like today?\");\n\n// Create a chat client\nChatClient chatClient = ChatClient.create(chatModel);\n\n// Get the chat response\nChatResponse response = chatClient.prompt(prompt)\n        .call()\n        .chatResponse();\n\n// Access the usage information\nUsage usage = response.getMetadata().getUsage();\n```\n\n== Prompt Cache Usage Metrics\n\nFor providers that support prompt caching, the `Usage` interface provides unified access to cache metrics without requiring provider-specific casting:\n\n```java\nUsage usage = response.getMetadata().getUsage();\n\n// Unified cache metrics — works across all providers\nLong cacheReadTokens = usage.getCacheReadInputTokens();\nLong cacheWriteTokens = usage.getCacheWriteInputTokens();\n\nif (cacheReadTokens != null && cacheReadTokens > 0) {\n    System.out.println(\"Cache hit: \" + cacheReadTokens + \" tokens read from cache\");\n}\nif (cacheWriteTokens != null && cacheWriteTokens > 0) {\n    System.out.println(\"Cache write: \" + cacheWriteTokens + \" tokens written to cache\");\n}\n```\n\nThese methods return `null` for providers that do not support prompt caching.\n\nThe following table shows prompt cache metrics availability by provider:\n\n[cols=\"1,1,1\"]\n|===\n|Provider |Cache Read Tokens |Cache Write Tokens\n\n|Anthropic |Yes |Yes (`cacheCreationInputTokens`)\n|AWS Bedrock |Yes |Yes\n|OpenAI |Yes (`cachedTokens`) |No\n|Google Gemini |Yes (`cachedContentTokenCount`) |No\n|DeepSeek |No |No\n|Mistral |No |No\n|Ollama |No |No\n|===\n\nNOTE: For detailed provider-specific cache metrics (such as per-modality cache breakdowns in Gemini), use `getNativeUsage()` to access the provider's native usage object.\n\n== Benefits\n\n**Standardization**: Provides a consistent way to handle usage across different AI models\n**Flexibility**: Supports model-specific usage data through the native usage feature\n**Simplification**: Reduces boilerplate code with the default implementation\n**Extensibility**: Easy to extend for specific model requirements while maintaining compatibility\n\n=== Type Safety Considerations\n\nWhen working with native usage data, consider type casting carefully:\n```java\n// Safe way to access native usage\nif (usage.getNativeUsage() instanceof org.springframework.ai.openai.api.OpenAiApi.Usage) {\n    org.springframework.ai.openai.api.OpenAiApi.Usage nativeUsage =\n        (org.springframework.ai.openai.api.OpenAiApi.Usage) usage.getNativeUsage();\n    // Work with native usage data\n}\n```\n"

    "content": "= Apache Cassandra Vector Store\n\nThis section walks you through setting up `CassandraVectorStore` to store document embeddings and perform similarity searches.\n\n== What is Apache Cassandra?\n\nlink:https://cassandra.apache.org[Apache Cassandra®] is a true open source distributed database renowned for linear scalability, proven fault-tolerance and low latency, making it the perfect platform for mission-critical transactional data.\n\nIts Vector Similarity Search (VSS) is based on the JVector library that ensures best-in-class performance and relevancy.\n\nA vector search in Apache Cassandra is done as simply as:\n[source,sql]\n----\nSELECT content FROM table ORDER BY content_vector ANN OF query_embedding;\n----\n\nMore docs on this can be read https://cassandra.apache.org/doc/latest/cassandra/getting-started/vector-search-quickstart.html[here].\n\nThis Spring AI Vector Store is designed to work for both brand-new RAG applications and be able to be retrofitted on top of existing data and tables.\n\nThe store can also be used for non-RAG use-cases in an existing database, e.g. semantic searches, geo-proximity searches, etc.\n\nThe store will automatically create, or enhance, the schema as needed according to its configuration. If you don't want the schema modifications, configure the store with `initializeSchema`.\n\nWhen using spring-boot-autoconfigure `initializeSchema` defaults to `false`, per Spring Boot standards, and you must opt-in to schema creation/modifications by setting `...initialize-schema=true` in the `application.properties` file.\n\n== What is JVector?\n\nlink:https://github.com/jbellis/jvector[JVector] is a pure Java embedded vector search engine.\n\nIt stands out from other HNSW Vector Similarity Search implementations by being:\n\n* Algorithmic-fast. JVector uses state of the art graph algorithms inspired by DiskANN and related research that offer high recall and low latency.\n* Implementation-fast. JVector uses the Panama SIMD API to accelerate index build and queries.\n* Memory efficient. JVector compresses vectors using product quantization so they can stay in memory during searches.\n* Disk-aware. JVector's disk layout is designed to do the minimum necessary iops at query time.\n* Concurrent. Index builds scale linearly to at least 32 threads. Double the threads, half the build time.\n* Incremental. Query your index as you build it. No delay between adding a vector and being able to find it in search results.\n* Easy to embed. API designed for easy embedding, by people using it in production.\n\n== Prerequisites\n\n1. A `EmbeddingModel` instance to compute the document embeddings. This is usually configured as a Spring Bean. Several options are available:\n\n- `Transformers Embedding` - computes the embedding in your local environment. The default is via ONNX and the all-MiniLM-L6-v2 Sentence Transformers. This just works.\n- If you want to use OpenAI's Embeddings - uses the OpenAI embedding endpoint. You need to create an account at link:https://platform.openai.com/signup[OpenAI Signup] and generate the api-key token at link:https://platform.openai.com/account/api-keys[API Keys].\n- There are many more choices, see `Embeddings API` docs.\n\n2. An Apache Cassandra instance, from version 5.0-beta1\na. link:https://cassandra.apache.org/_/quickstart.html[DIY Quick Start]\nb. For a managed offering https://astra.datastax.com/[Astra DB] offers a healthy free tier offering.\n\n== Dependencies\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nTIP: For dependency management, we recommend using the Spring AI BOM as explained in the xref:getting-started.adoc#dependency-management[Dependency Management] section.\n\nAdd these dependencies to your project:\n\n* For just the Cassandra Vector Store:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-cassandra-store</artifactId>\n</dependency>\n----\n\n* Or, for everything you need in a RAG application (using the default ONNX Embedding Model):\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-vector-store-cassandra</artifactId>\n</dependency>\n----\n\n== Configuration Properties\n\nYou can use the following properties in your Spring Boot configuration to customize the Apache Cassandra vector store.\n\n[cols=\"2,1\",stripes=even]\n|===\n|Property|Default Value\n\n|`spring.ai.vectorstore.cassandra.keyspace`|springframework\n|`spring.ai.vectorstore.cassandra.table`|ai_vector_store\n|`spring.ai.vectorstore.cassandra.initialize-schema`|false\n|`spring.ai.vectorstore.cassandra.index-name`|\n|`spring.ai.vectorstore.cassandra.content-column-name`|content\n|`spring.ai.vectorstore.cassandra.embedding-column-name`|embedding\n|`spring.ai.vectorstore.cassandra.fixed-thread-pool-executor-size`|16\n|===\n\n== Usage\n\n=== Basic Usage\n\nCreate a CassandraVectorStore instance as a Spring Bean:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(CqlSession session, EmbeddingModel embeddingModel) {\n    return CassandraVectorStore.builder(embeddingModel)\n        .session(session)\n        .keyspace(\"my_keyspace\")\n        .table(\"my_vectors\")\n        .build();\n}\n----\n\nOnce you have the vector store instance, you can add documents and perform searches:\n\n[source,java]\n----\n// Add documents\nvectorStore.add(List.of(\n    new Document(\"1\", \"content1\", Map.of(\"key1\", \"value1\")),\n    new Document(\"2\", \"content2\", Map.of(\"key2\", \"value2\"))\n));\n\n// Search with filters\nList<Document> results = vectorStore.similaritySearch(\n    SearchRequest.query(\"search text\")\n        .withTopK(5)\n        .withSimilarityThreshold(0.7f)\n        .withFilterExpression(\"metadata.key1 == 'value1'\")\n);\n----\n\n=== Advanced Configuration\n\nFor more complex use cases, you can configure additional settings in your Spring Bean:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(CqlSession session, EmbeddingModel embeddingModel) {\n    return CassandraVectorStore.builder(embeddingModel)\n        .session(session)\n        .keyspace(\"my_keyspace\")\n        .table(\"my_vectors\")\n        // Configure primary keys\n        .partitionKeys(List.of(\n            new SchemaColumn(\"id\", DataTypes.TEXT),\n            new SchemaColumn(\"category\", DataTypes.TEXT)\n        ))\n        .clusteringKeys(List.of(\n            new SchemaColumn(\"timestamp\", DataTypes.TIMESTAMP)\n        ))\n        // Add metadata columns with optional indexing\n        .addMetadataColumns(\n            new SchemaColumn(\"category\", DataTypes.TEXT, SchemaColumnTags.INDEXED),\n            new SchemaColumn(\"score\", DataTypes.DOUBLE)\n        )\n        // Customize column names\n        .contentColumnName(\"text\")\n        .embeddingColumnName(\"vector\")\n        // Performance tuning\n        .fixedThreadPoolExecutorSize(32)\n        // Schema management\n        .initializeSchema(true)\n        // Custom batching strategy\n        .batchingStrategy(new TokenCountBatchingStrategy())\n        .build();\n}\n----\n\n=== Connection Configuration\n\nThere are two ways to configure the connection to Cassandra:\n\n* Using an injected CqlSession (recommended):\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(CqlSession session, EmbeddingModel embeddingModel) {\n    return CassandraVectorStore.builder(embeddingModel)\n        .session(session)\n        .keyspace(\"my_keyspace\")\n        .table(\"my_vectors\")\n        .build();\n}\n----\n\n* Using connection details directly in the builder:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(EmbeddingModel embeddingModel) {\n    return CassandraVectorStore.builder(embeddingModel)\n        .contactPoint(new InetSocketAddress(\"localhost\", 9042))\n        .localDatacenter(\"datacenter1\")\n        .keyspace(\"my_keyspace\")\n        .build();\n}\n----\n\n=== Metadata Filtering\n\nYou can leverage the generic, portable metadata filters with the CassandraVectorStore. For metadata columns to be searchable they must be either primary keys or SAI indexed. To make non-primary-key columns indexed, configure the metadata column with the `SchemaColumnTags.INDEXED`.\n\nFor example, you can use either the text expression language:\n\n[source,java]\n----\nvectorStore.similaritySearch(\n    SearchRequest.builder().query(\"The World\")\n        .topK(5)\n        .filterExpression(\"country in ['UK', 'NL'] && year >= 2020\").build());\n----\n\nor programmatically using the expression DSL:\n\n[source,java]\n----\nFilter.Expression f = new FilterExpressionBuilder()\n    .and(\n        f.in(\"country\", \"UK\", \"NL\"), \n        f.gte(\"year\", 2020)\n    ).build();\n\nvectorStore.similaritySearch(\n    SearchRequest.builder().query(\"The World\")\n        .topK(5)\n        .filterExpression(f).build());\n----\n\nThe portable filter expressions get automatically converted into link:https://cassandra.apache.org/doc/latest/cassandra/developing/cql/index.html[CQL queries].\n\n== Advanced Example: Vector Store on top of Wikipedia Dataset\n\nThe following example demonstrates how to use the store on an existing schema. Here we use the schema from the https://github.com/datastax-labs/colbert-wikipedia-data project which comes with the full wikipedia dataset ready vectorized for you.\n\nFirst, create the schema in the Cassandra database:\n\n[source,bash]\n----\nwget https://s.apache.org/colbert-wikipedia-schema-cql -O colbert-wikipedia-schema.cql\ncqlsh -f colbert-wikipedia-schema.cql\n----\n\nThen configure the store using the builder pattern:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(CqlSession session, EmbeddingModel embeddingModel) {\n    List<SchemaColumn> partitionColumns = List.of(\n        new SchemaColumn(\"wiki\", DataTypes.TEXT),\n        new SchemaColumn(\"language\", DataTypes.TEXT),\n        new SchemaColumn(\"title\", DataTypes.TEXT)\n    );\n\n    List<SchemaColumn> clusteringColumns = List.of(\n        new SchemaColumn(\"chunk_no\", DataTypes.INT),\n        new SchemaColumn(\"bert_embedding_no\", DataTypes.INT)\n    );\n\n    List<SchemaColumn> extraColumns = List.of(\n        new SchemaColumn(\"revision\", DataTypes.INT),\n        new SchemaColumn(\"id\", DataTypes.INT)\n    );\n\n    return CassandraVectorStore.builder()\n        .session(session)\n        .embeddingModel(embeddingModel)\n        .keyspace(\"wikidata\")\n        .table(\"articles\")\n        .partitionKeys(partitionColumns)\n        .clusteringKeys(clusteringColumns)\n        .contentColumnName(\"body\")\n        .embeddingColumnName(\"all_minilm_l6_v2_embedding\")\n        .indexName(\"all_minilm_l6_v2_ann\")\n        .initializeSchema(false)\n        .addMetadataColumns(extraColumns)\n        .primaryKeyTranslator((List<Object> primaryKeys) -> {\n            if (primaryKeys.isEmpty()) {\n                return \"test§¶0\";\n            }\n            return String.format(\"%s§¶%s\", primaryKeys.get(2), primaryKeys.get(3));\n        })\n        .documentIdTranslator((id) -> {\n            String[] parts = id.split(\"§¶\");\n            String title = parts[0];\n            int chunk_no = parts.length > 1 ? Integer.parseInt(parts[1]) : 0;\n            return List.of(\"simplewiki\", \"en\", title, chunk_no, 0);\n        })\n        .build();\n}\n\n@Bean\npublic EmbeddingModel embeddingModel() {\n    // default is ONNX all-MiniLM-L6-v2 which is what we want\n    return new TransformersEmbeddingModel();\n}\n----\n\n=== Loading the Complete Wikipedia Dataset\n\nTo load the full wikipedia dataset:\n\n1. Download `simplewiki-sstable.tar` from https://s.apache.org/simplewiki-sstable-tar (this will take a while, the file is tens of GBs)\n\n2. Load the data:\n[source,bash]\n----\ntar -xf simplewiki-sstable.tar -C ${CASSANDRA_DATA}/data/wikidata/articles-*/\nnodetool import wikidata articles ${CASSANDRA_DATA}/data/wikidata/articles-*/\n----\n\n[NOTE]\n====\n* If you have existing data in this table, check the tarball's files don't clobber existing sstables when doing the `tar`.\n* An alternative to `nodetool import` is to just restart Cassandra.\n* If there are any failures in the indexes they will be rebuilt automatically.\n====\n\n== Accessing the Native Client\n\nThe Cassandra Vector Store implementation provides access to the underlying native Cassandra client (`CqlSession`) through the `getNativeClient()` method:\n\n[source,java]\n----\nCassandraVectorStore vectorStore = context.getBean(CassandraVectorStore.class);\nOptional<CqlSession> nativeClient = vectorStore.getNativeClient();\n\nif (nativeClient.isPresent()) {\n    CqlSession session = nativeClient.get();\n    // Use the native client for Cassandra-specific operations\n}\n----\n\nThe native client gives you access to Cassandra-specific features and operations that might not be exposed through the `VectorStore` interface.\n"

    "content": "= Azure Cosmos DB\n\nThis section walks you through setting up `CosmosDBVectorStore` to store document embeddings and perform similarity searches.\n\n== What is Azure Cosmos DB?\n\nlink:https://azure.microsoft.com/en-us/services/cosmos-db/[Azure Cosmos DB] is Microsoft's globally distributed cloud-native database service designed for mission-critical applications.\nIt offers high availability, low latency, and the ability to scale horizontally to meet modern application demands.\nIt was built from the ground up with global distribution, fine-grained multi-tenancy, and horizontal scalability at its core.\nIt is a foundational service in Azure, used by most of Microsoft’s mission critical applications at global scale, including Teams, Skype, Xbox Live, Office 365, Bing, Azure Active Directory, Azure Portal, Microsoft Store, and many others.\nIt is also used by thousands of external customers including OpenAI for ChatGPT and other mission-critical AI applications that require elastic scale, turnkey global distribution, and low latency and high availability across the planet.\n\n== What is DiskANN?\n\nDiskANN (Disk-based Approximate Nearest Neighbor Search) is an innovative technology used in Azure Cosmos DB to enhance the performance of vector searches.\nIt enables efficient and scalable similarity searches across high-dimensional data by indexing embeddings stored in Cosmos DB.\n\nDiskANN provides the following benefits:\n\n* **Efficiency**: By utilizing disk-based structures, DiskANN significantly reduces the time required to find nearest neighbors compared to traditional methods.\n* **Scalability**: It can handle large datasets that exceed memory capacity, making it suitable for various applications, including machine learning and AI-driven solutions.\n* **Low Latency**: DiskANN minimizes latency during search operations, ensuring that applications can retrieve results quickly even with substantial data volumes.\n\nIn the context of Spring AI for Azure Cosmos DB, vector searches will create and leverage DiskANN indexes to ensure optimal performance for similarity queries.\n\n== Setting up Azure Cosmos DB Vector Store

names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nAdd the following dependency to your Maven project:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-vector-store-azure-cosmos-db</artifactId>\n</dependency>\n----\n\n== Configuration Properties\n\nThe following configuration properties are available for the Cosmos DB vector store:\n\n[stripes=even]\n|===\n| Property | Description\n\n| spring.ai.vectorstore.cosmosdb.databaseName | The name of the Cosmos DB database to use.\n| spring.ai.vectorstore.cosmosdb.containerName | The name of the Cosmos DB container to use.\n| spring.ai.vectorstore.cosmosdb.partitionKeyPath | The path for the partition key.\n| spring.ai.vectorstore.cosmosdb.metadataFields | Comma-separated list of metadata fields.\n|

[DefaultAzureCredential](https://learn.microsoft.com/azure/developer/java/sdk/authentication/credential-chains#defaultazurecredential-overview) will be used).\n|===\n\n\n== Complex Searches with Filters\n\nYou can perform more complex searches using filters in the Cosmos DB vector store.\nBelow is a sample demonstrating how to use filters in your search queries.\n\n[source,java]\n----\nMap<String, Object> metadata1 = new HashMap<>();\nmetadata1.put(\"country\", \"UK\");\nmetadata1.put(\"year\", 2021);\nmetadata1.put(\"city\",

    "content": "= Azure AI Service\n\nThis section will walk you through setting up the `AzureVectorStore` to store document embeddings and perform similarity searches using the Azure AI Search Service.\n\nlink:https://azure.microsoft.com/en-us/products/ai-services/ai-search/[Azure AI Search] is a versatile cloud-hosted cloud information retrieval system that is part of Microsoft's larger AI platform. Among other features, it allows users to query information using vector-based storage and retrieval.\n\n== Prerequisites\n\n1. Azure Subscription: You will need an link:https://azure.microsoft.com/en-us/free/[Azure subscription] to use any Azure service.\n2. Azure AI Search Service: Create an link:https://portal.azure.com/#create/Microsoft.Search[AI Search service]. Once the service is created, obtain the admin apiKey from the `Keys` section under `Settings` and retrieve the endpoint from the `Url` field under the `Overview` section.\n3. (Optional) Azure OpenAI Service: Create an Azure link:https://portal.azure.com/#create/Microsoft.AIServicesOpenAI[OpenAI service]. **NOTE:** You may have to fill out a separate form to gain access to Azure Open AI services. Once the service is created, obtain the endpoint and apiKey from the `Keys and Endpoint` section under `Resource Management`.\n\n== Configuration\n\nOn startup, the `AzureVectorStore` can  attempt to create a new index within your AI Search service instance if you've opted in by setting the relevant `initialize-schema` `boolean` property to `true` in the constructor or, if using Spring Boot, setting `...initialize-schema=true`  in your `application.properties` file.\n\n\nNOTE: this is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default.\n\nAlternatively, you can create the index manually.\n\nTo set up an AzureVectorStore, you will need the settings retrieved from the prerequisites above along with your index name:\n\n* Azure AI Search Endpoint\n* Azure AI Search Key\n* (optional) Azure OpenAI API Endpoint\n* (optional) Azure OpenAI API Key\n\nYou can provide these values as OS environment variables.\n\n[source,bash]\n----\nexport AZURE_AI_SEARCH_API_KEY=<My AI Search API Key>\nexport AZURE_AI_SEARCH_ENDPOINT=<My AI Search Index>\nexport OPENAI_API_KEY=<My Azure AI API Key> (Optional)\n----\n\n[NOTE]\n====\nYou can replace Azure Open AI implementation with any valid OpenAI implementation that supports the Embeddings interface. For example, you could use Spring AI's Open AI or `TransformersEmbedding` implementations for embeddings instead of the Azure implementation.\n====\n\n== Dependencies\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nAdd these dependencies to your project:\n\n=== 1. Select an Embeddings interface implementation. You can choose between:\n\n[tabs]\n======\nOpenAI Embedding::\n+\n[source,xml]\n----\n<dependency>\n   <groupId>org.springframework.ai</groupId>\n   <artifactId>spring-ai-starter-model-openai</artifactId>\n</dependency>\n----\n\nAzure AI Embedding::\n+\n[source,xml]\n----\n<dependency>\n <groupId>org.springframework.ai</groupId>\n <artifactId>spring-ai-starter-model-azure-openai</artifactId>\n</dependency>\n----\n\nLocal Sentence Transformers Embedding::\n+\n[source,xml]\n----\n<dependency>\n <groupId>org.springframework.ai</groupId>\n <artifactId>spring-ai-starter-model-transformers</artifactId>\n</dependency>\n----\n======\n\n=== 2. Azure (AI Search) Vector Store\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-azure-store</artifactId>\n</dependency>\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n== Configuration Properties\n\nYou can use the following properties in your Spring Boot configuration to customize the Azure vector store.\n\n[stripes=even]\n|===\n|Property|Default value\n\n|`spring.ai.vectorstore.azure.url`|\n|`spring.ai.vectorstore.azure.api-key`|\n|`spring.ai.vectorstore.azure.useKeylessAuth`|false\n|`spring.ai.vectorstore.azure.initialize-schema`|false\n|`spring.ai.vectorstore.azure.index-name`|spring_ai_azure_vector_store\n|`spring.ai.vectorstore.azure.default-top-k`|4\n|`spring.ai.vectorstore.azure.default-similarity-threshold`|0.0\n|`spring.ai.vectorstore.azure.content-field-name`|content\n|`spring.ai.vectorstore.azure.embedding-field-name`|embedding\n|`spring.ai.vectorstore.azure.metadata-field-name`|metadata\n|===\n\n\n== Sample Code\n\nTo configure an Azure `SearchIndexClient` in your application, you can use the following code:\n\n[source,java]\n----\n@Bean\npublic SearchIndexClient searchIndexClient() {\n  return new SearchIndexClientBuilder().endpoint(System.getenv(\"AZURE_AI_SEARCH_ENDPOINT\"))\n    .credential(new AzureKeyCredential(System.getenv(\"AZURE_AI_SEARCH_API_KEY\")))\n    .buildClient();\n}\n----\n\nTo create a vector store, you can use the following code by injecting the `SearchIndexClient` bean created in the above sample along with an `EmbeddingModel` provided by the Spring AI library that implements the desired Embeddings interface.\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(SearchIndexClient searchIndexClient, EmbeddingModel embeddingModel) {\n\n  return AzureVectorStore.builder(searchIndexClient, embeddingModel)\n    .initializeSchema(true)\n    // Define the metadata fields to be used\n    // in the similarity search filters.\n    .filterMetadataFields(List.of(MetadataField.text(\"country\"), MetadataField.int64(\"year\"),\n            MetadataField.date(\"activationDate\")))\n    .defaultTopK(5)\n    .defaultSimilarityThreshold(0.7)\n    .indexName(\"spring-ai-document-index\")\n    .build();\n}\n----\n\n[NOTE]\n====\nYou must list explicitly all metadata field names and types for any metadata key used in the filter expression. The list above registers filterable metadata fields: `country` of type `TEXT`, `year` of type `INT64`, and `active` of type `BOOLEAN`.\n\nIf the filterable metadata fields are expanded with new entries, you have to (re)upload/update the documents with this metadata.\n====\n\nIn your main code, create some documents:\n\n[source,java]\n----\nList<Document> documents = List.of(\n\tnew Document(\"Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!\", Map.of(\"country\", \"BG\", \"year\", 2020)),\n\tnew Document(\"The World is Big and Salvation Lurks Around the Corner\"),\n\tnew Document(\"You walk forward facing the past and you turn back toward the future.\", Map.of(\"country\", \"NL\", \"year\", 2023)));\n----\n\nAdd the documents to your vector store:\n\n[source,java]\n----\nvectorStore.add(documents);\n----\n\nAnd finally, retrieve documents similar to a query:\n\n[source,java]\n----\nList<Document> results = vectorStore.similaritySearch(\n    SearchRequest.builder()\n      .query(\"Spring\")\n      .topK(5).build());\n----\n\nIf all goes well, you should retrieve the document containing the text \"Spring AI rocks!!\".\n\n=== Metadata filtering\n\nYou can leverage the generic, portable link:https://docs.spring.io/spring-ai/reference/api/vectordbs.html#_metadata_filters[metadata filters] with AzureVectorStore as well.\n\nFor example, you can use either the text expression language:\n\n[source,java]\n----\nvectorStore.similaritySearch(\n   SearchRequest.builder()\n      .query(\"The World\")\n      .topK(TOP_K)\n      .similarityThreshold(SIMILARITY_THRESHOLD)\n      .filterExpression(\"country in ['UK', 'NL'] && year >= 2020\").build());\n----\n\nor programmatically using the expression DSL:\n\n[source,java]\n----\nFilterExpressionBuilder b = new FilterExpressionBuilder();\n\nvectorStore.similaritySearch(\n    SearchRequest.builder()\n      .query(\"The World\")\n      .topK(TOP_K)\n      .similarityThreshold(SIMILARITY_THRESHOLD)\n      .filterExpression(b.and(\n         b.in(\"country\", \"UK\", \"NL\"),\n         b.gte(\"year\", 2020)).build()).build());\n----\n\nThe portable filter expressions get automatically converted into the proprietary Azure Search link:https://learn.microsoft.com/en-us/azure/search/search-query-odata-filter[OData filters]. For example, the following portable filter expression:\n\n[source,sql]\n----\ncountry in ['UK', 'NL'] && year >= 2020\n----\n\nis converted into the following Azure OData link:https://learn.microsoft.com/en-us/azure/search/search-query-odata-filter[filter expression]:\n\n[source,graphql]\n----\n$filter search.in(meta_country, 'UK,NL', ',') and meta_year ge 2020\n----\n\n== Custom Field Names\n\nBy default, the Azure Vector Store uses the following field names in the Azure AI Search index:\n\n* `content` - for document text\n* `embedding` - for vector embeddings\n* `metadata` - for document metadata\n\nHowever, when working with existing Azure AI Search indexes that use different field names, you can configure custom field names to match your index schema. This allows you to integrate Spring AI with pre-existing indexes without needing to modify them.\n\n=== Use Cases\n\nCustom field names are particularly useful when:\n\n* **Integrating with existing indexes**: Your organization already has Azure AI Search indexes with established field naming conventions (e.g., `chunk_text`, `vector`, `meta_data`).\n* **Following naming standards**: Your team follows specific naming conventions that differ from the defaults.\n* **Migrating from other systems**: You're migrating from another vector database or search system and want to maintain consistent field names.\n\n=== Configuration via Properties\n\nYou can configure custom field names using Spring Boot application properties:\n\n[source,properties]\n----\nspring.ai.vectorstore.azure.url=${AZURE_AI_SEARCH_ENDPOINT}\nspring.ai.vectorstore.azure.api-key=${AZURE_AI_SEARCH_API_KEY}\nspring.ai.vectorstore.azure.index-name=my-existing-index\nspring.ai.vectorstore.azure.initialize-schema=false\n\n# Custom field names to match existing index schema\nspring.ai.vectorstore.azure.content-field-name=chunk_text\nspring.ai.vectorstore.azure.embedding-field-name=vector\nspring.ai.vectorstore.azure.metadata-field-name=meta_data\n----\n\nIMPORTANT: When using an existing index with custom field names, set `initialize-schema=false` to prevent Spring AI from trying to create a new index with the default schema.\n\n=== Configuration via Builder API\n\nAlternatively, you can configure custom field names programmatically using the builder API:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(SearchIndexClient searchIndexClient, EmbeddingModel embeddingModel) {\n\n\treturn AzureVectorStore.builder(searchIndexClient, embeddingModel)\n\t\t.indexName(\"my-existing-index\")\n\t\t.initializeSchema(false) // Don't create schema - use existing index\n\t\t// Configure custom field names to match existing index\n\t\t.contentFieldName(\"chunk_text\")\n\t\t.embeddingFieldName(\"vector\")\n\t\t.metadataFieldName(\"meta_data\")\n\t\t.filterMetadataFields(List.of(\n\t\t\tMetadataField.text(\"category\"),\n\t\t\tMetadataField.text(\"source\")))\n\t\t.build();\n}\n----\n\n=== Complete Example: Working with Existing Index\n\nHere's a complete example showing how to use Spring AI with an existing Azure AI Search index that has custom field names:\n\n[source,java]\n----\n@Configuration\npublic class VectorStoreConfig {\n\n\t@Bean\n\tpublic SearchIndexClient searchIndexClient() {\n\t\treturn new SearchIndexClientBuilder()\n\t\t\t.endpoint(System.getenv(\"AZURE_AI_SEARCH_ENDPOINT\"))\n\t\t\t.credential(new AzureKeyCredential(System.getenv(\"AZURE_AI_SEARCH_API_KEY\")))\n\t\t\t.buildClient();\n\t}\n\n\t@Bean\n\tpublic VectorStore vectorStore(SearchIndexClient searchIndexClient,\n\t\t\tEmbeddingModel embeddingModel) {\n\n\t\treturn AzureVectorStore.builder(searchIndexClient, embeddingModel)\n\t\t\t.indexName(\"production-documents-index\")\n\t\t\t.initializeSchema(false) // Use existing index\n\t\t\t// Map to existing index field names\n\t\t\t.contentFieldName(\"document_text\")\n\t\t\t.embeddingFieldName(\"text_vector\")\n\t\t\t.metadataFieldName(\"document_metadata\")\n\t\t\t// Define filterable metadata fields from existing schema\n\t\t\t.filterMetadataFields(List.of(\n\t\t\t\tMetadataField.text(\"department\"),\n\t\t\t\tMetadataField.int64(\"year\"),\n\t\t\t\tMetadataField.date(\"created_date\")))\n\t\t\t.defaultTopK(10)\n\t\t\t.defaultSimilarityThreshold(0.75)\n\t\t\t.build();\n\t}\n}\n----\n\nYou can then use the vector store as normal:\n\n[source,java]\n----\n// Search using the existing index with custom field names\nList<Document> results = vectorStore.similaritySearch(\n\tSearchRequest.builder()\n\t\t.query(\"artificial intelligence\")\n\t\t.topK(5)\n\t\t.filterExpression(\"department == 'Engineering' && year >= 2023\")\n\t\t.build());\n\n// The results contain documents with text from the 'document_text' field\nresults.forEach(doc -> System.out.println(doc.getText()));\n----\n\n=== Creating New Index with Custom Field Names\n\nYou can also create a new index with custom field names by setting `initializeSchema=true`:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(SearchIndexClient searchIndexClient,\n\t\tEmbeddingModel embeddingModel) {\n\n\treturn AzureVectorStore.builder(searchIndexClient, embeddingModel)\n\t\t.indexName(\"new-custom-index\")\n\t\t.initializeSchema(true) // Create new index with custom field names\n\t\t.contentFieldName(\"text_content\")\n\t\t.embeddingFieldName(\"content_vector\")\n\t\t.metadataFieldName(\"doc_metadata\")\n\t\t.filterMetadataFields(List.of(\n\t\t\tMetadataField.text(\"category\"),\n\t\t\tMetadataField.text(\"author\")))\n\t\t.build();\n}\n----\n\nThis will create a new Azure AI Search index with your custom field names, allowing you to establish your own naming conventions from the start.\n\n== Accessing the Native Client\n\nThe Azure Vector Store implementation provides access to the underlying native Azure Search client (`SearchClient`) through the `getNativeClient()` method:\n\n[source,java]\n----\nAzureVectorStore vectorStore = context.getBean(AzureVectorStore.class);\nOptional<SearchClient> nativeClient = vectorStore.getNativeClient();\n\nif (nativeClient.isPresent()) {\n    SearchClient client = nativeClient.get();\n    // Use the native client for Azure Search-specific operations\n}\n----\n\nThe native client gives you access to Azure Search-specific features and operations that might not be exposed through the `VectorStore` interface.\n"

    "content": "= Chroma\n\nThis section will walk you through setting up the Chroma VectorStore to store document embeddings and perform similarity searches.\n\nlink:https://docs.trychroma.com/[Chroma] is the open-source embedding database. It gives you the tools to store document embeddings, content, and metadata and to search through those embeddings, including metadata filtering.\n\n== Prerequisites\n\n1. Access to ChromaDB. Compatible with link:https://trychroma.com/signup[Chroma Cloud], or  <<run Chroma Locally, setup local ChromaDB>> in the appendix shows how to set up a DB locally with a Docker container.\n   - For Chroma Cloud: You'll need your API key, tenant name, and database name from your Chroma Cloud dashboard.\n   - For local ChromaDB: No additional configuration required beyond starting the container.\n\n2. `EmbeddingModel` instance to compute the document embeddings. Several options are available:\n- If required, an API key for the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] to generate the embeddings stored by the `ChromaVectorStore`.\n\nOn startup, the `ChromaVectorStore` creates the required collection if one is not provisioned already.\n\n== Auto-configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the Chroma Vector Store.\nTo enable it, add the following dependency to your project's Maven `pom.xml` file:\n\n[source, xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-vector-store-chroma</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-vector-store-chroma'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nTIP: Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Maven Central and/or Snapshot Repositories to your build file.\n\n\nThe vector store implementation can initialize the requisite schema for you, but you must opt-in by specifying the `initializeSchema` boolean in the appropriate constructor or by setting `...initialize-schema=true` in the `application.properties` file.\n\nNOTE: this is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default.\n\n\n\n\nAdditionally, you will need a configured `EmbeddingModel` bean. Refer to the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] section for more information.\n\nHere is an example of the needed bean:\n\n[source,java]\n----\n@Bean\npublic EmbeddingModel embeddingModel() {\n    // Can be any other EmbeddingModel implementation.\n    return new OpenAiEmbeddingModel(OpenAiApi.builder().apiKey(System.getenv(\"OPENAI_API_KEY\")).build());\n}\n----\n\nTo connect to Chroma you need to provide access details for your instance.\nA simple configuration can either be provided via Spring Boot's _application.properties_,\n\n[source,properties]\n----\n# Chroma Vector Store connection properties\nspring.ai.vectorstore.chroma.client.host=<your Chroma instance host>  // for Chroma Cloud: api.trychroma.com\nspring.ai.vectorstore.chroma.client.port=<your Chroma instance port> // for Chroma Cloud: 443\nspring.ai.vectorstore.chroma.client.key-token=<your access token (if configure)> // for Chroma Cloud: use the API key\nspring.ai.vectorstore.chroma.client.username=<your username (if configure)>\nspring.ai.vectorstore.chroma.client.password=<your password (if configure)>\n\n# Chroma Vector Store tenant and database properties (required for Chroma Cloud)\nspring.ai.vectorstore.chroma.tenant-name=<your tenant name> // default: SpringAiTenant\nspring.ai.vectorstore.chroma.database-name=<your database name> // default: SpringAiDatabase\n\n# Chroma Vector Store collection properties\nspring.ai.vectorstore.chroma.initialize-schema=<true or false>\nspring.ai.vectorstore.chroma.collection-name=<your collection name>\n\n# Chroma Vector Store configuration properties\n\n# OpenAI API key if the OpenAI auto-configuration is used.\nspring.ai.openai.api.key=<OpenAI Api-key>\n----\n\nPlease have a look at the list of xref:#_configuration_properties[configuration parameters] for the vector store to learn about the default values and configuration options.\n\nNow you can auto-wire the Chroma Vector Store in your application and use it\n\n[source,java]\n----\n@Autowired VectorStore vectorStore;\n\n// ...\n\nList <Document> documents = List.of(\n    new Document(\"Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!

Check the `ChromaWhereIT` for an example.\n\nFor ChromaDB secured with link:https://docs.trychroma.com/usage-guide#basic-authentication[Basic Authentication] use the `ChromaApi#withBasicAuth(<your user>, <your password>)` method to set your credentials. Check the `BasicAuthChromaWhereIT` for an example.\n====\n\n=== Chroma Cloud Configuration\n\nFor Chroma Cloud, you need to provide the tenant and database names from your Chroma Cloud instance. Here's an example configuration:\n\n[source,properties]\n----\n# Chroma Cloud connection\nspring.ai.vectorstore.chroma.client.host=api.trychroma.com\nspring.ai.vectorstore.chroma.client.port=443\nspring.ai.vectorstore.chroma.client.key-token=<your-chroma-cloud-api-key>\n\n# Chroma Cloud tenant and database (required)\nspring.ai.vectorstore.chroma.tenant-name=<your-tenant-id>\nspring.ai.vectorstore.chroma.database-name=<your-database-name>\n\n# Collection configuration\nspring.ai.vectorstore.chroma.collection-name=my-collection\nspring.ai.vectorstore.chroma.initialize-schema=true\n----\n\n[NOTE]\n====\nFor Chroma Cloud:\n- The host should be `api.trychroma.com`\n- The port should be `443` (HTTPS)\n- You must provide your API key via `key-token`\n- The tenant and database names must match your Chroma Cloud configuration\n- Set `initialize-schema=true` to automatically create the collection if it doesn't exist (it won't recreate existing tenant/database)\n====\n\n== Metadata filtering\n\nYou can leverage the generic, portable link:https://docs.spring.io/spring-ai/reference/api/vectordbs.html#_metadata_filters[metadata filters] with ChromaVector store as well.\n\nFor example, you can use either the text expression language:\n\n[source,java]\n----\nvectorStore.similaritySearch(\n                    SearchRequest.builder()\n                            .query(\"The World\")\n                            .topK(TOP_K)\n                            .similarityThreshold(SIMILARITY_THRESHOLD)\n                            .filterExpression(\"author in ['john', 'jill'] && article_type == 'blog'\").build());\n----\n\nor programmatically using the `Filter.Expression` DSL:\n\n[source,java]\n----\nFilterExpressionBuilder b = new FilterExpressionBuilder();\n\nvectorStore.similaritySearch(SearchRequest.builder()\n                    .query(\"The World\")\n                    .topK(TOP_K)\n                    .similarityThreshold(SIMILARITY_THRESHOLD)\n                    .filterExpression(b.and(\n                            b.in(\"john\", \"jill\"),\n                            b.eq(\"article_type\", \"blog\")).build()).build());\n----\n\nNOTE: Those (portable) filter expressions get automatically converted into the proprietary Chroma `where` link:https://docs.trychroma.com/usage-guide#using-where-filters[filter expressions].\n\nFor example, this portable filter expression:\n\n```sql\nauthor in ['john', 'jill'] && article_type == 'blog'\n```\n\nis converted into the proprietary Chroma format\n\n```json\n{\"$and\":[\n\t{\"author\": {\"$in\": [\"john\", \"jill\"]}},\n\t{\"article_type\":{\"$eq\":\"blog\"}}]\n}\n```\n\n\n== Manual Configuration\n\nIf you prefer to configure the Chroma Vector Store manually, you can do so by creating a `ChromaVectorStore` bean in your Spring Boot application.\n\nAdd these dependencies to your project:\n* Chroma VectorStore.\n\n[source,xml]\n----\n<dependency>\n  <groupId>org.springframework.ai</groupId>\n  <artifactId>spring-ai-chroma-store</artifactId>\n</dependency>\n----\n\n* OpenAI: Required for calculating embeddings. You can use any other embedding model implementation.\n\n[source,xml]\n----\n<dependency>\n <groupId>org.springframework.ai</groupId>\n <artifactId>spring-ai-starter-model-openai</artifactId>\n</dependency>\n----\n\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\n=== Sample Code\n\nCreate a `RestClient.Builder` instance with proper ChromaDB authorization configurations and Use it to create a `ChromaApi` instance:\n\n[source,java]\n----\n@Bean\npublic RestClient.Builder builder() {\n    return RestClient.builder().requestFactory(new SimpleClientHttpRequestFactory());\n}\n\n\n@Bean\npublic ChromaApi chromaApi(RestClient.Builder restClientBuilder) {\n   String chromaUrl = \"http://localhost:8000\";\n   ChromaApi chromaApi = new ChromaApi(chromaUrl, restClientBuilder);\n   return chromaApi;\n}\n----\n\nIntegrate with OpenAI's embeddings by adding the Spring Boot OpenAI starter to your project. This provides you with an implementation of the Embeddings client:\n\n[source,java]\n----\n@Bean\npublic VectorStore chromaVectorStore(EmbeddingModel embeddingModel, ChromaApi chromaApi) {\n return ChromaVectorStore.builder(chromaApi, embeddingModel)\n    .tenantName(\"your-tenant-name\") // default: SpringAiTenant\n    .databaseName(\"your-database-name\") // default: SpringAiDatabase\n    .collectionName(\"TestCollection\")\n    .initializeSchema(true)\n    .build();\n}\n----\n\nIn your main code, create some documents:\n\n[source,java]\n----\nList<Document> documents = List.of(\n new Document(\"Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!\", Map.of(\"meta1\", \"meta1\")),\n new Document(\"The World is Big and Salvation Lurks Around the Corner\"),\n new Document(\"You walk forward facing the past and you turn back toward the future.\", Map.of(\"meta2\", \"meta2\")));\n----\n\nAdd the documents to your vector store:\n\n[source,java]\n----\nvectorStore.add(documents);\n----\n\nAnd finally, retrieve documents similar to a query:\n\n[source,java]\n----\nList<Document> results = vectorStore.similaritySearch(\"Spring\");\n----\n\nIf all goes well, you should retrieve the document containing the text \"Spring AI rocks!!\".\n\n\n=== Run Chroma Locally\n\n```shell\ndocker run -it --rm --name chroma -p 8000:8000 ghcr.io/chroma-core/chroma:1.0.0\n```\n\nStarts a chroma store at <http://localhost:8000/api/v1>\n"

    "content": "= MariaDB Vector Store\n\nThis section walks you through setting up `MariaDBVectorStore` to store document embeddings and perform similarity searches.\n\nlink:https://mariadb.org/projects/mariadb-vector/[MariaDB Vector] is part of MariaDB 11.7 and enables storing and searching over machine learning-generated embeddings.\nIt provides efficient vector similarity search capabilities using vector indexes, supporting both cosine similarity and Euclidean distance metrics.\n\n== Prerequisites\n\n* A running MariaDB (11.7+) instance. The following options are available:\n** link:https://hub.docker.com/_/mariadb[Docker] image\n** link:https://mariadb.org/download/[MariaDB Server]\n** link:https://mariadb.com/products/skysql/[MariaDB SkySQL]\n* If required, an API key for the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] to generate the embeddings stored by the `MariaDBVectorStore`.\n\n== Auto-Configuration\n\n[NOTE]\n====\nThere has been a significant change in the Spring AI auto-configuration, starter modules' artifact names.\nPlease refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information.\n====\n\nSpring AI provides Spring Boot auto-configuration for the MariaDB Vector Store.\nTo enable it, add the following dependency to your project's Maven `pom.xml` file:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-vector-store-mariadb</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-vector-store-mariadb'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nThe vector store implementation can initialize the required schema for you, but you must opt-in by specifying the `initializeSchema` boolean in the appropriate constructor or by setting `...initialize-schema=true` in the `application.properties` file.\n\nNOTE: This is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default.\n\nAdditionally, you will need a configured `EmbeddingModel` bean.\nRefer to the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] section for more information.\n\nFor example, to use the xref:api/embeddings/openai-embeddings.adoc[OpenAI EmbeddingModel], add the following dependency:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-openai</artifactId>\n</dependency>\n----\n\nTIP: Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Maven Central and/or Snapshot Repositories to your build file.\n\nNow you can auto-wire the `MariaDBVectorStore` in your application:\n\n[source,java]\n----\n@Autowired VectorStore vectorStore;\n\n// ...\n\nList<Document> documents = List.of(\n    new Document(\"Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!\", Map.of(\"meta1\", \"meta1\")),\n    new Document(\"The World is Big and Salvation Lurks Around the Corner\"),\n    new Document(\"You walk forward facing the past and you turn back toward the future.\", Map.of(\"meta2\", \"meta2\")));\n\n// Add the documents to MariaDB\nvectorStore.add(documents);\n\n// Retrieve documents similar to a query\nList<Document> results = vectorStore.similaritySearch(SearchRequest.builder().query(\"Spring\").topK(5).build());\n----\n\n[[mariadbvector-properties]]\n=== Configuration Properties\n\nTo connect to MariaDB and use the `MariaDBVectorStore`, you need to provide access details for your instance.\nA simple configuration can be provided via Spring Boot's `application.yml`:\n\n[source,yaml]\n----\nspring:\n  datasource:\n    url: jdbc:mariadb://localhost/db\n    username: myUser\n    password: myPassword\n  ai:\n    vectorstore:\n      mariadb:\n        initialize-schema: true\n        distance-type: COSINE\n        dimensions: 1536\n----\n\nTIP: If you run MariaDB Vector as a Spring Boot dev service via link:https://docs.spring.io/spring-boot/reference/features/dev-services.html#features.dev-services.docker-compose[Docker Compose]\nor link:https://docs.spring.io/spring-boot/reference/features/dev-services.html#features.dev-services.testcontainers[Testcontainers],\nyou don't need to configure URL, username and password since they are autoconfigured by Spring Boot.\n\nProperties starting with `spring.ai.vectorstore.mariadb.*` are used to configure the `MariaDBVectorStore`:\n\n[cols=\"2,5,1\",stripes=even]\n|===\n|Property | Description | Default Value\n\n|`spring.ai.vectorstore.mariadb.initialize-schema`| Whether to initialize the required schema | `false`\n|`spring.ai.vectorstore.mariadb.distance-type`| Search distance type. Use `COSINE` (default) or `EUCLIDEAN`. If vectors are normalized to length 1, you can use `EUCLIDEAN` for best performance.| `COSINE`\n|`spring.ai.vectorstore.mariadb.dimensions`| Embeddings dimension. If not specified explicitly, will retrieve dimensions from the provided `EmbeddingModel`. | `1536`\n|`spring.ai.vectorstore.mariadb.remove-existing-vector-store-table` | Deletes the existing vector store table on startup. | `false`\n|`spring.ai.vectorstore.mariadb.schema-name` | Vector store schema name | `null`\n|`spring.ai.vectorstore.mariadb.table-name` | Vector store table name | `vector_store`\n|`spring.ai.vectorstore.mariadb.schema-validation` | Enables schema and table name validation to ensure they are valid and existing objects. | `false`\n|===\n\nTIP: If you configure a custom schema and/or table name, consider enabling schema validation by setting `spring.ai.vectorstore.mariadb.schema-validation=true`.\nThis ensures the correctness of the names and reduces the risk of SQL injection attacks.\n\n== Manual Configuration\n\nInstead of using the Spring Boot auto-configuration, you can manually configure the MariaDB vector store.\nFor this you need to add the following dependencies to your project:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.boot</groupId>\n    <artifactId>spring-boot-starter-jdbc</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>org.mariadb.jdbc</groupId>\n    <artifactId>mariadb-java-client</artifactId>\n    <scope>runtime</scope>\n</dependency>\n\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-mariadb-store</artifactId>\n</dependency>\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nThen create the `MariaDBVectorStore` bean using the builder pattern:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(JdbcTemplate jdbcTemplate, EmbeddingModel embeddingModel) {\n    return MariaDBVectorStore.builder(jdbcTemplate, embeddingModel)\n        .dimensions(1536)                      // Optional: defaults to 1536\n        .distanceType(MariaDBDistanceType.COSINE) // Optional: defaults to COSINE\n        .schemaName(\"mydb\")                    // Optional: defaults to null\n        .vectorTableName(\"custom_vectors\")     // Optional: defaults to \"vector_store\"\n        .contentFieldName(\"text\")             // Optional: defaults to \"content\"\n        .embeddingFieldName(\"embedding\")      // Optional: defaults to \"embedding\"\n        .idFieldName(\"doc_id\")                // Optional: defaults to \"id\"\n        .metadataFieldName(\"meta\")           // Optional: defaults to \"metadata\"\n        .initializeSchema(true)               // Optional: defaults to false\n        .schemaValidation(true)              // Optional: defaults to false\n        .removeExistingVectorStoreTable(false) // Optional: defaults to false\n        .maxDocumentBatchSize(10000)         // Optional: defaults to 10000\n        .build();\n}\n\n// This can be any EmbeddingModel implementation\n@Bean\npublic EmbeddingModel embeddingModel() {\n    return new OpenAiEmbeddingModel(new OpenAiApi(System.getenv(\"OPENAI_API_KEY\")));\n}\n----\n\n== Metadata Filtering\n\nYou can leverage the generic, portable xref:api/vectordbs.adoc#metadata-filters[metadata filters] with MariaDB Vector store.\n\nFor example, you can use either the text expression language:\n\n[source,java]\n----\nvectorStore.similaritySearch(\n    SearchRequest.builder()\n        .query(\"The World\")\n        .topK(TOP_K)\n        .similarityThreshold(SIMILARITY_THRESHOLD)\n        .filterExpression(\"author in ['john', 'jill'] && article_type == 'blog'\").build());\n----\n\nor programmatically using the `Filter.Expression` DSL:\n\n[source,java]\n----\nFilterExpressionBuilder b = new FilterExpressionBuilder();\n\nvectorStore.similaritySearch(SearchRequest.builder()\n    .query(\"The World\")\n    .topK(TOP_K)\n    .similarityThreshold(SIMILARITY_THRESHOLD)\n    .filterExpression(b.and(\n        b.in(\"author\", \"john\", \"jill\"),\n        b.eq(\"article_type\", \"blog\")).build()).build());\n----\n\nNOTE: These filter expressions are automatically converted into the equivalent MariaDB JSON path expressions.\n\n== Similarity Scores\n\nThe MariaDB Vector Store automatically calculates similarity scores for documents returned from similarity searches.\nThese scores provide a normalized measure of how closely each document matches your search query.\n\n=== Score Calculation\n\nSimilarity scores are calculated using the formula `score = 1.0 - distance`, where:\n\n* Score: A value between `0.0` and `1.0`, where `1.0` indicates perfect similarity and `0.0` indicates no similarity\n* Distance: The raw distance value calculated using the configured distance type (`COSINE` or `EUCLIDEAN`)\n\nThis means that documents with smaller distances (more similar) will have higher scores, making the results more intuitive to interpret.\n\n=== Accessing Scores\n\nYou can access the similarity score for each document through the `getScore()` method:\n\n[source,java]\n----\nList<Document> results = vectorStore.similaritySearch(\n    SearchRequest.builder()\n        .query(\"Spring AI\")\n        .topK(5)\n        .build());\n\nfor (Document doc : results) {\n    double score = doc.getScore();  // Value between 0.0 and 1.0\n    System.out.println(\"Document: \" + doc.getText());\n    System.out.println(\"Similarity Score: \" + score);\n}\n----\n\n=== Search Results Ordering\n\nSearch results are automatically ordered by similarity score in descending order (highest score first).\nThis ensures that the most relevant documents appear at the top of your results.\n\n=== Distance Metadata\n\nIn addition to the similarity score, the raw distance value is still available in the document metadata:\n\n[source,java]\n----\nfor (Document doc : results) {\n    double score = doc.getScore();\n    float distance = (Float) doc.getMetadata().get(\"distance\");\n\n    System.out.println(\"Score: \" + score + \", Distance: \" + distance);\n}\n----\n\n=== Similarity Threshold\n\nWhen using similarity thresholds in your search requests, specify the threshold as a score value (`0.0` to `1.0`) rather than a distance:\n\n[source,java]\n----\nList<Document> results = vectorStore.similaritySearch(\n    SearchRequest.builder()\n        .query(\"Spring AI\")\n        .topK(10)\n        .similarityThreshold(0.8)  // Only return documents with score >= 0.8\n        .build());\n----\n\nThis makes threshold values consistent and intuitive - higher values mean more restrictive searches that only return highly similar documents.\n\n== Accessing the Native Client\n\nThe MariaDB Vector Store implementation provides access to the underlying native JDBC client (`JdbcTemplate`) through the `getNativeClient()` method:\n\n[source,java]\n----\nMariaDBVectorStore vectorStore = context.getBean(MariaDBVectorStore.class);\nOptional<JdbcTemplate> nativeClient = vectorStore.getNativeClient();\n\nif (nativeClient.isPresent()) {\n    JdbcTemplate jdbc = nativeClient.get();\n    // Use the native client for MariaDB-specific operations\n}\n----\n\nThe native client gives you access to MariaDB-specific features and operations that might not be exposed through the `VectorStore` interface.\n"

For this you need to add the `spring-ai-opensearch-store` to your project:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-opensearch-store</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file:\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-opensearch-store'\n}\n----\n\nTIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.\n\nCreate an OpenSearch client bean:\n\n[source,java]\n----\n@Bean\npublic OpenSearchClient openSearchClient() {\n    RestClient restClient = RestClient.builder(\n        HttpHost.create(\"http://localhost:9200\"))\n        .build();\n    \n    return new OpenSearchClient(new RestClientTransport(\n        restClient, new JacksonJsonpMapper()));\n}\n----\n\nThen create the `OpenSearchVectorStore` bean using the builder pattern:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(OpenSearchClient openSearchClient, EmbeddingModel embeddingModel) {\n    return OpenSearchVectorStore.builder(openSearchClient, embeddingModel)\n        .index(\"custom-index\")                // Optional: defaults to \"spring-ai-document-index\"\n        .similarityFunction(\"l2\")             // Optional: defaults to \"cosinesimil\"\n        .useApproximateKnn(true)              // Optional: defaults to false (exact k-NN)\n        .dimensions(1536)                     // Optional: defaults to 1536 or embedding model's dimensions\n        .initializeSchema(true)               // Optional: defaults to false\n        .batchingStrategy(new TokenCountBatchingStrategy()) // Optional: defaults to TokenCountBatchingStrategy\n        .build();\n}\n\n// This can be any EmbeddingModel implementation\n@Bean\npublic EmbeddingModel embeddingModel() {\n    return new OpenAiEmbeddingModel(new OpenAiApi(System.getenv(\"OPENAI_API_KEY\")));\n}\n----\n\n== Metadata Filtering\n\nYou can leverage the generic, portable xref:api/vectordbs.adoc#metadata-filters[metadata filters] with OpenSearch as well.\n\nFor example, you can use either the text expression language:\n\n[source,java]\n----\nvectorStore.similaritySearch(\n    SearchRequest.builder()\n        .query(\"The World\")\n        .topK(TOP_K)\n        .similarityThreshold(SIMILARITY_THRESHOLD)\n        .filterExpression(\"author in ['john', 'jill'] && 'article_type' == 'blog'\").build());\n----\n\nor programmatically using the `Filter.Expression` DSL:\n\n[source,java]\n----\nFilterExpressionBuilder b = new FilterExpressionBuilder();\n\nvectorStore.similaritySearch(SearchRequest.builder()\n    .query(\"The World\")\n    .topK(TOP_K)\n    .similarityThreshold(SIMILARITY_THRESHOLD)\n    .filterExpression(b.and(\n        b.in(\"author\", \"john\", \"jill\"),\n        b.eq(\"article_type\", \"blog\")).build()).build());\n----\n\nNOTE: Those (portable) filter expressions get automatically converted into the proprietary OpenSearch link:https://opensearch.org/docs/latest/query-dsl/full-text/query-string/[Query string query].\n\nFor example, this portable filter expression:\n\n[source,sql]\n----\nauthor in ['john', 'jill'] && 'article_type' == 'blog'\n----\n\nis converted into the proprietary OpenSearch filter format:\n\n[source,text]\n----\n(metadata.author:john OR jill) AND metadata.article_type:blog\n----\n\n== Accessing the Native Client\n\nThe OpenSearch Vector Store implementation provides access to the underlying native OpenSearch client (`OpenSearchClient`) through the `getNativeClient()` method:\n\n[source,java]\n----\nOpenSearchVectorStore vectorStore = context.getBean(OpenSearchVectorStore.class);\nOptional<OpenSearchClient> nativeClient = vectorStore.getNativeClient();\n\nif (nativeClient.isPresent()) {\n    OpenSearchClient client = nativeClient.get();\n    // Use the native client for OpenSearch-specific operations\n}\n----\n\nThe native client gives you access to OpenSearch-specific features and operations that might not be exposed through the `VectorStore` interface.\n"

It provides different capabilities that let users identify both exact and approximate nearest neighbors. It is designed to work seamlessly with other PostgreSQL features, including indexing and querying.\n\n== Prerequisites\n\nFirst you need access to PostgreSQL instance with enabled `vector`, `hstore` and `uuid-ossp` extensions.\n\nTIP: You can run a PGvector database as a Spring Boot dev service via xref:api/docker-compose.adoc[Docker Compose] or xref:api/testcontainers.adoc[Testcontainers].

For this you need to add the `spring-ai-redis-store` to your project:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-redis-store</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file.\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-redis-store'\n}\n----\n\nCreate a `JedisPooled` bean:\n\n[source,java]\n----\n@Bean\npublic JedisPooled jedisPooled() {\n    return new JedisPooled(\"<host>\", 6379);\n}\n----\n\nThen create the `RedisVectorStore` bean using the builder pattern:\n\n[source,java]\n----\n@Bean\npublic VectorStore vectorStore(JedisPooled jedisPooled, EmbeddingModel embeddingModel) {\n    return RedisVectorStore.builder(jedisPooled, embeddingModel)\n        .indexName(\"custom-index\")                // Optional: defaults to \"spring-ai-index\"\n        .prefix(\"custom-prefix\")                  // Optional: defaults to \"embedding:\"\n        .contentFieldName(\"content\")              // Optional: field for document content\n        .embeddingFieldName(\"embedding\")          // Optional: field for vector embeddings\n        .vectorAlgorithm(Algorithm.HNSW)          // Optional: HNSW or FLAT (defaults to HNSW)\n        .distanceMetric(DistanceMetric.COSINE)    // Optional: COSINE, L2, or IP (defaults to COSINE)\n        .hnswM(16)                                // Optional: HNSW connections (defaults to 16)\n        .hnswEfConstruction(200)                  // Optional: HNSW build parameter (defaults to 200)\n        .hnswEfRuntime(10)                        // Optional: HNSW search parameter (defaults to 10)\n        .defaultRangeThreshold(0.8)               // Optional: default radius for range searches\n        .textScorer(TextScorer.BM25)              // Optional: text scoring algorithm (defaults to BM25)\n        .metadataFields(                          // Optional: define metadata fields for filtering\n            MetadataField.tag(\"country\"),\n            MetadataField.numeric(\"year\"),\n            MetadataField.text(\"description\"))\n        .initializeSchema(true)                   // Optional: defaults to false\n        .batchingStrategy(new TokenCountBatchingStrategy()) // Optional: defaults to TokenCountBatchingStrategy\n        .build();\n}\n\n// This can be any EmbeddingModel implementation\n@Bean\npublic EmbeddingModel embeddingModel() {\n    return new OpenAiEmbeddingModel(new OpenAiApi(System.getenv(\"OPENAI_API_KEY\")));\n}\n----\n\n[NOTE]\n====\nYou must list explicitly all metadata field names and types (`TAG`, `TEXT`, or `NUMERIC`) for any metadata field used in filter expressions.\nThe `metadataFields` above registers filterable metadata fields: `country` of type `TAG`, `year` of type `NUMERIC`.\n====\n\n== Accessing the Native Client\n\nThe Redis Vector Store implementation provides access to the underlying native Redis client (`JedisPooled`) through the `getNativeClient()` method:\n\n[source,java]\n----\nRedisVectorStore vectorStore = context.getBean(RedisVectorStore.class);\nOptional<JedisPooled> nativeClient = vectorStore.getNativeClient();\n\nif (nativeClient.isPresent()) {\n    JedisPooled jedis = nativeClient.get();\n    // Use the native client for Redis-specific operations\n}\n----\n\nThe native client gives you access to Redis-specific features and operations that might not be exposed through the `VectorStore` interface.\n\n== Distance Metrics\n\nThe Redis Vector Store supports three distance metrics for vector similarity:\n\n* **COSINE**: Cosine similarity (default) - measures the cosine of the angle between vectors\n* **L2**: Euclidean distance - measures the straight-line distance between vectors\n* **IP**: Inner Product - measures the dot product between vectors\n\nEach metric is automatically normalized to a 0-1 similarity score, where 1 is most similar.\n\n[source,java]\n----\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .distanceMetric(DistanceMetric.COSINE)  // or L2, IP\n    .build();\n----\n\n== HNSW Algorithm Configuration\n\nThe Redis Vector Store uses the HNSW (Hierarchical Navigable Small World) algorithm by default for efficient approximate nearest neighbor search. You can tune the HNSW parameters for your specific use case:\n\n[source,java]\n----\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .vectorAlgorithm(Algorithm.HNSW)\n    .hnswM(32)                    // Maximum outgoing connections per node (default: 16)\n    .hnswEfConstruction(100)      // Connections during index building (default: 200)\n    .hnswEfRuntime(50)            // Connections during search (default: 10)\n    .build();\n----\n\nParameter guidelines:\n\n* **M**: Higher values improve recall but increase memory usage and index time. Typical values: 12-48.\n* **EF_CONSTRUCTION**: Higher values improve index quality but increase build time. Typical values: 100-500.\n* **EF_RUNTIME**: Higher values improve search accuracy but increase latency. Typical values: 10-100.\n\nFor smaller datasets or when exact results are required, use the FLAT algorithm instead:\n\n[source,java]\n----\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .vectorAlgorithm(Algorithm.FLAT)\n    .build();\n----\n\n== Text Search\n\nThe Redis Vector Store provides text search capabilities using Redis Query Engine's full-text search features. This allows you to find documents based on keywords and phrases in TEXT fields:\n\n[source,java]\n----\n// Search for documents containing specific text\nList<Document> textResults = vectorStore.searchByText(\n    \"machine learning\",   // search query\n    \"content\",            // field to search (must be TEXT type)\n    10,                   // limit\n    \"category == 'AI'\"    // optional filter expression\n);\n----\n\nText search supports:\n\n* Single word searches\n* Phrase searches with exact matching when `inOrder` is true\n* Term-based searches with OR semantics when `inOrder` is false\n* Stopword filtering to ignore common words\n* Multiple text scoring algorithms\n\nConfigure text search behavior at construction time:\n\n[source,java]\n----\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .textScorer(TextScorer.TFIDF)                    // Text scoring algorithm\n    .inOrder(true)                                   // Match terms in order\n    .stopwords(Set.of(\"is\", \"a\", \"the\", \"and\"))      // Ignore common words\n    .metadataFields(MetadataField.text(\"description\")) // Define TEXT fields\n    .build();\n----\n\n=== Text Scoring Algorithms\n\nSeveral text scoring algorithms are available:\n\n* **BM25**: Modern version of TF-IDF with term saturation (default)\n* **TFIDF**: Classic term frequency-inverse document frequency\n* **BM25STD**: Standardized BM25\n* **DISMAX**: Disjunction max\n* **DOCSCORE**: Document score\n\nScores are normalized to a 0-1 range for consistency with vector similarity scores.\n\n== Range Search\n\nThe range search returns all documents within a specified radius threshold, rather than a fixed number of nearest neighbors:\n\n[source,java]\n----\n// Search with explicit radius\nList<Document> rangeResults = vectorStore.searchByRange(\n    \"AI and machine learning\",  // query\n    0.8,                        // radius (similarity threshold)\n    \"category == 'AI'\"          // optional filter expression\n);\n----\n\nYou can also set a default range threshold at construction time:\n\n[source,java]\n----\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .defaultRangeThreshold(0.8)  // Set default threshold\n    .build();\n\n// Use default threshold\nList<Document> results = vectorStore.searchByRange(\"query\");\n----\n\nRange search is useful when you want to retrieve all relevant documents above a similarity threshold, rather than limiting to a specific count.\n\n== Semantic Caching\n\nSemantic caching is a powerful optimization technique that leverages Redis vector search capabilities to cache and retrieve AI chat responses based on the *semantic similarity* of user queries rather than exact string matching.\nThis enables intelligent response reuse even when users phrase similar questions differently.\n\n=== Why Semantic Caching?\n\nTraditional caching relies on exact key matches, which fails when users ask semantically equivalent questions with different wording:\n\n* \"What is the capital of France?\"\n* \"Tell me France's capital city\"\n* \"Which city is the capital of France?\"\n\nAll three queries have the same answer, but traditional caching would treat them as different requests, resulting in redundant LLM API calls.\nSemantic caching solves this by comparing the *meaning* of queries using vector embeddings.\n\n**Benefits:**\n\n* **Reduced API costs**: Avoid redundant calls to expensive LLM APIs\n* **Lower latency**: Return cached responses instantly instead of waiting for model inference\n* **Improved scalability**: Handle higher query volumes without proportional API cost increases\n* **Consistent responses**: Return identical answers for semantically similar questions\n\n=== Auto-configuration\n\nSpring AI provides Spring Boot auto-configuration for the Redis Semantic Cache.\nTo enable it, add the following dependency to your project's Maven `pom.xml` file:\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-vector-store-redis-semantic-cache</artifactId>\n</dependency>\n----\n\nor to your Gradle `build.gradle` build file:\n\n[source,groovy]\n----\ndependencies {\n    implementation 'org.springframework.ai:spring-ai-starter-vector-store-redis-semantic-cache'\n}\n----\n\nTIP: The auto-configuration provides a default embedding model optimized for semantic caching (`redis/langcache-embed-v1`).\nYou can override this by providing your own `EmbeddingModel` bean.\n\n[[semantic-cache-properties]]\n=== Configuration Properties\n\nProperties starting with `spring.ai.vectorstore.redis.semantic-cache.*` configure the semantic cache:\n\n[cols=\"2,5,1\",stripes=even]\n|===\n|Property | Description | Default Value\n\n|`spring.ai.vectorstore.redis.semantic-cache.enabled`| Enable or disable the semantic cache | `true`\n|`spring.ai.vectorstore.redis.semantic-cache.host`| Redis server host | `localhost`\n|`spring.ai.vectorstore.redis.semantic-cache.port`| Redis server port | `6379`\n|`spring.ai.vectorstore.redis.semantic-cache.similarity-threshold`| Similarity threshold for cache hits (0.0-1.0). Higher values require closer semantic matches. | `0.95`\n|`spring.ai.vectorstore.redis.semantic-cache.index-name`| Name of the Redis search index for cache entries | `semantic-cache-index`\n|`spring.ai.vectorstore.redis.semantic-cache.prefix`| Key prefix for cached entries in Redis | `semantic-cache:`\n|===\n\nExample configuration in `application.yml`:\n\n[source,yaml]\n----\nspring:\n  ai:\n    vectorstore:\n      redis:\n        semantic-cache:\n          enabled: true\n          host: localhost\n          port: 6379\n          similarity-threshold: 0.85\n          index-name: my-app-cache\n          prefix: \"my-app:semantic-cache:\"\n----\n\n=== Using the SemanticCacheAdvisor\n\nThe `SemanticCacheAdvisor` integrates seamlessly with Spring AI's `ChatClient` advisor pattern.\nIt automatically caches responses and returns cached results for similar queries:\n\n[source,java]\n----\n@Autowired\nprivate SemanticCache semanticCache;\n\n@Autowired\nprivate ChatModel chatModel;\n\npublic void example() {\n    // Create the cache advisor\n    SemanticCacheAdvisor cacheAdvisor = SemanticCacheAdvisor.builder()\n        .cache(semanticCache)\n        .build();\n\n    // First query - calls the LLM and caches the response\n    ChatResponse response1 = ChatClient.builder(chatModel)\n        .build()\n        .prompt(\"What is the capital of France?\")\n        .advisors(cacheAdvisor)\n        .call()\n        .chatResponse();\n\n    // Similar query - returns cached response (no LLM call)\n    ChatResponse response2 = ChatClient.builder(chatModel)\n        .build()\n        .prompt(\"Tell me the capital city of France\")\n        .advisors(cacheAdvisor)\n        .call()\n        .chatResponse();\n\n    // response1 and response2 contain the same cached answer\n}\n----\n\nThe advisor automatically:\n\n1. Checks the cache for semantically similar queries before calling the LLM\n2. Returns cached responses when a match is found above the similarity threshold\n3. Caches new responses after successful LLM calls\n4. Supports both synchronous and streaming chat operations\n\n=== Direct Cache Usage\n\nYou can also interact with the `SemanticCache` directly for fine-grained control:\n\n[source,java]\n----\n@Autowired\nprivate SemanticCache semanticCache;\n\n// Store a response with a query\nsemanticCache.set(\"What is the capital of France?\", chatResponse);\n\n// Store with TTL (time-to-live) for automatic expiration\nsemanticCache.set(\"What's the weather today?\", weatherResponse, Duration.ofHours(1));\n\n// Retrieve a semantically similar response\nOptional<ChatResponse> cached = semanticCache.get(\"Tell me France's capital\");\n\nif (cached.isPresent()) {\n    // Use the cached response\n    String answer = cached.get().getResult().getOutput().getText();\n}\n\n// Clear all cached entries\nsemanticCache.clear();\n----\n\n=== Manual Configuration\n\nFor more control, you can manually configure the semantic cache components:\n\n[source,java]\n----\n@Configuration\npublic class SemanticCacheConfig {\n\n    @Bean\n    public JedisPooled jedisPooled() {\n        return new JedisPooled(\"localhost\", 6379);\n    }\n\n    @Bean\n    public SemanticCache semanticCache(JedisPooled jedisPooled, EmbeddingModel embeddingModel) {\n        return DefaultSemanticCache.builder()\n            .jedisClient(jedisPooled)\n            .embeddingModel(embeddingModel)\n            .distanceThreshold(0.3)           // Lower = stricter matching\n            .indexName(\"my-semantic-cache\")\n            .prefix(\"cache:\")\n            .build();\n    }\n\n    @Bean\n    public SemanticCacheAdvisor semanticCacheAdvisor(SemanticCache cache) {\n        return SemanticCacheAdvisor.builder()\n            .cache(cache)\n            .build();\n    }\n}\n----\n\n=== Cache Isolation with Namespaces\n\nFor multi-tenant applications or when you need separate cache spaces, use different index names to isolate cache entries:\n\n[source,java]\n----\n// Create isolated caches for different users or contexts\nSemanticCache user1Cache = DefaultSemanticCache.builder()\n    .jedisClient(jedisPooled)\n    .embeddingModel(embeddingModel)\n    .indexName(\"user-1-cache\")\n    .build();\n\nSemanticCache user2Cache = DefaultSemanticCache.builder()\n    .jedisClient(jedisPooled)\n    .embeddingModel(embeddingModel)\n    .indexName(\"user-2-cache\")\n    .build();\n\n// Each user gets their own isolated cache space\nSemanticCacheAdvisor user1Advisor = SemanticCacheAdvisor.builder()\n    .cache(user1Cache)\n    .build();\n----\n\n=== System Prompt Isolation\n\nThe `SemanticCacheAdvisor` automatically isolates cached responses based on the system prompt.\nThis ensures that the same user query with different system prompts returns different cached responses, which is essential for applications with multiple AI personas or context-dependent behavior.\n\n[source,java]\n----\nSemanticCacheAdvisor cacheAdvisor = SemanticCacheAdvisor.builder()\n    .cache(semanticCache)\n    .build();\n\n// Query with technical support persona\nChatResponse technicalResponse = ChatClient.builder(chatModel)\n    .build()\n    .prompt()\n    .system(\"You are a technical support specialist. Provide detailed technical answers.\")\n    .user(\"How do I reset my password?\")\n    .advisors(cacheAdvisor)\n    .call()\n    .chatResponse();\n\n// Same query with customer service persona - cache MISS (different context)\nChatResponse serviceResponse = ChatClient.builder(chatModel)\n    .build()\n    .prompt()\n    .system(\"You are a friendly customer service agent. Keep responses brief and helpful.\")\n    .user(\"How do I reset my password?\")\n    .advisors(cacheAdvisor)\n    .call()\n    .chatResponse();\n\n// Same query with technical support persona again - cache HIT\nChatResponse technicalAgain = ChatClient.builder(chatModel)\n    .build()\n    .prompt()\n    .system(\"You are a technical support specialist. Provide detailed technical answers.\")\n    .user(\"How do I reset my password?\")\n    .advisors(cacheAdvisor)\n    .call()\n    .chatResponse();\n// Returns the cached technical response\n----\n\n**How it works:**\n\nThe advisor computes a deterministic hash of the system prompt and uses it as a metadata filter when storing and retrieving cached responses:\n\n* Same user question + same system prompt → cache hit\n* Same user question + different system prompt → cache miss (separate cache entry)\n* Queries without a system prompt share a common cache space\n\n=== Context-Aware Cache API\n\nFor advanced use cases, you can use the context-aware cache methods directly:\n\n[source,java]\n----\n// Store with explicit context hash\nString contextHash = \"technical-support-context\";\nsemanticCache.set(\"How do I reset my password?\", response, contextHash);\n\n// Retrieve with context filtering\nOptional<ChatResponse> cached = semanticCache.get(\"How do I reset my password?\", contextHash);\n\n// Different context hash returns empty (no match)\nOptional<ChatResponse> otherContext = semanticCache.get(\"How do I reset my password?\", \"billing-context\");\n----\n\n=== Tuning the Similarity Threshold\n\nThe similarity threshold determines how closely a query must match a cached entry to be considered a hit.\nThe threshold is expressed as a value between 0.0 and 1.0:\n\n* **Higher threshold (e.g., 0.95)**: Requires very close semantic matches.\nReduces false positives but may miss valid cache hits.\n* **Lower threshold (e.g., 0.70)**: Allows broader semantic matches.\nIncreases cache hit rate but may return less relevant cached responses.\n\n[source,java]\n----\n// Strict matching - only very similar queries hit the cache\nSemanticCache strictCache = DefaultSemanticCache.builder()\n    .jedisClient(jedisPooled)\n    .embeddingModel(embeddingModel)\n    .distanceThreshold(0.2)  // Strict (distance-based, lower = stricter)\n    .build();\n\n// Lenient matching - broader semantic similarity accepted\nSemanticCache lenientCache = DefaultSemanticCache.builder()\n    .jedisClient(jedisPooled)\n    .embeddingModel(embeddingModel)\n    .distanceThreshold(0.5)  // Lenient\n    .build();\n----\n\nTIP: Start with a higher threshold (stricter matching) and gradually lower it based on your application's tolerance for semantic variation.\n\n=== TTL and Cache Expiration\n\nCached responses can be configured with a time-to-live (TTL) for automatic expiration.\nThis is essential for time-sensitive data:\n\n[source,java]\n----\n// Cache weather data for 1 hour\nsemanticCache.set(\"What's the weather in New York?\", weatherResponse, Duration.ofHours(1));\n\n// Cache general knowledge indefinitely (no TTL)\nsemanticCache.set(\"What is photosynthesis?\", scienceResponse);\n\n// Redis automatically removes expired entries\n----\n\n=== How It Works\n\nThe semantic cache operates using the following flow:\n\n1. **Query embedding**: When a query arrives, it is converted to a vector embedding using the configured `EmbeddingModel`\n\n2. **Vector search**: Redis performs a range-based vector search (`VECTOR_RANGE`) to find cached entries within the similarity threshold\n\n3. **Cache hit**: If a semantically similar query is found, the cached `ChatResponse` is returned immediately\n\n4. **Cache miss**: If no match is found, the query proceeds to the LLM, and the response is cached for future use\n\nThe implementation leverages Redis's efficient vector indexing (HNSW algorithm) for fast similarity searches, even with large cache sizes.\n"

    "content": "[[vector-databases]]\n= Vector Databases\n\nA vector database is a specialized type of database that plays an essential role in AI applications.\n\nIn vector databases, queries differ from traditional relational databases.\nInstead of exact matches, they perform similarity searches.\nWhen given a vector as a query, a vector database returns vectors that are \"`similar`\" to the query vector.\nFurther details on how this similarity is calculated at a high-level is provided in a xref:api/vectordbs/understand-vectordbs.adoc#vectordbs-similarity[Vector Similarity].\n\nVector databases are used to integrate your data with AI models.\nThe first step in their usage is to load your data into a vector database.\nThen, when a user query is to be sent to the AI model, a set of similar documents is first retrieved.\nThese documents then serve as the context for the user's question and are sent to the AI model, along with the user's query.\nThis technique is known as xref:concepts.adoc#concept-rag[Retrieval Augmented Generation (RAG)].\n\nThe following sections describe the Spring AI interface for using multiple vector database implementations and some high-level sample usage.\n\nThe last section is intended to demystify the underlying approach of similarity searching in vector databases.\n\n[[api-overview]]\n== API Overview\nThis section serves as a guide to the `VectorStore` interface and its associated classes within the Spring AI framework.\n\nSpring AI offers an abstracted API for interacting with vector databases through the `VectorStore` interface and its read-only counterpart, the `VectorStoreRetriever` interface.\n\n=== VectorStoreRetriever Interface\n\nSpring AI provides a read-only interface called `VectorStoreRetriever` that exposes only the document retrieval functionality:\n\n[source,java]\n----\n@FunctionalInterface\npublic interface VectorStoreRetriever {\n\n    List<Document> similaritySearch(SearchRequest request);\n\n    default List<Document> similaritySearch(String query) {\n        return this.similaritySearch(SearchRequest.builder().query(query).build());\n    }\n}\n----\n\nThis functional interface is designed for use cases where you only need to retrieve documents from a vector store without performing any mutation operations. It follows the principle of least privilege by exposing only the necessary functionality for document retrieval.\n\n=== VectorStore Interface\n\nThe `VectorStore` interface extends `VectorStoreRetriever` and adds mutation capabilities:\n\n[source,java]\n----\npublic interface VectorStore extends DocumentWriter, VectorStoreRetriever {\n\n    default String getName() {\n\t\treturn this.getClass().getSimpleName();\n\t}\n\n    void add(List<Document> documents);\n\n    void delete(List<String> idList);\n\n    void delete(Filter.Expression filterExpression);\n\n    default void delete(String filterExpression) { ... }\n\n    default <T> Optional<T> getNativeClient() {\n\t\treturn Optional.empty();\n\t}\n}\n----\n\nThe `VectorStore` interface combines both read and write operations, allowing you to add, delete, and search for documents in a vector database.\n\n=== SearchRequest Builder\n\n[source,java]\n----\npublic class SearchRequest {\n\n\tpublic static final double SIMILARITY_THRESHOLD_ACCEPT_ALL = 0.0;\n\n\tpublic static final int DEFAULT_TOP_K = 4;\n\n\tprivate String query = \"\";\n\n\tprivate int topK = DEFAULT_TOP_K;\n\n\tprivate double similarityThreshold = SIMILARITY_THRESHOLD_ACCEPT_ALL;\n\n\t@Nullable\n\tprivate Filter.Expression filterExpression;\n\n    public static Builder from(SearchRequest originalSearchRequest) {\n\t\treturn builder().query(originalSearchRequest.getQuery())\n\t\t\t.topK(originalSearchRequest.getTopK())\n\t\t\t.similarityThreshold(originalSearchRequest.getSimilarityThreshold())\n\t\t\t.filterExpression(originalSearchRequest.getFilterExpression());\n\t}\n\n\tpublic static class Builder {\n\n\t\tprivate final SearchRequest searchRequest = new SearchRequest();\n\n\t\tpublic Builder query(String query) {\n\t\t\tAssert.notNull(query, \"Query can not be null.\");\n\t\t\tthis.searchRequest.query = query;\n\t\t\treturn this;\n\t\t}\n\n\t\tpublic Builder topK(int topK) {\n\t\t\tAssert.isTrue(topK >= 0, \"TopK should be positive.\");\n\t\t\tthis.searchRequest.topK = topK;\n\t\t\treturn this;\n\t\t}\n\n\t\tpublic Builder similarityThreshold(double threshold) {\n\t\t\tAssert.isTrue(threshold >= 0 && threshold <= 1, \"Similarity threshold must be in [0,1] range.\");\n\t\t\tthis.searchRequest.similarityThreshold = threshold;\n\t\t\treturn this;\n\t\t}\n\n\t\tpublic Builder similarityThresholdAll() {\n\t\t\tthis.searchRequest.similarityThreshold = 0.0;\n\t\t\treturn this;\n\t\t}\n\n\t\tpublic Builder filterExpression(@Nullable Filter.Expression expression) {\n\t\t\tthis.searchRequest.filterExpression = expression;\n\t\t\treturn this;\n\t\t}\n\n\t\tpublic Builder filterExpression(@Nullable String textExpression) {\n\t\t\tthis.searchRequest.filterExpression = (textExpression != null)\n\t\t\t\t\t? new FilterExpressionTextParser().parse(textExpression) : null;\n\t\t\treturn this;\n\t\t}\n\n\t\tpublic SearchRequest build() {\n\t\t\treturn this.searchRequest;\n\t\t}\n\n\t}\n\n\tpublic String getQuery() {...}\n\tpublic int getTopK() {...}\n\tpublic double getSimilarityThreshold() {...}\n\tpublic Filter.Expression getFilterExpression() {...}\n}\n\n----\n\nTo insert data into the vector database, encapsulate it within a `Document` object.\nThe `Document` class encapsulates content from a data source, such as a PDF or Word document, and includes text represented as a string.\nIt also contains metadata in the form of key-value pairs, including details such as the filename.\n\nUpon insertion into the vector database, the text content is transformed into a numerical array, or a `float[]`, known as vector embeddings, using an embedding model. Embedding models, such as https://en.wikipedia.org/wiki/Word2vec[Word2Vec], https://en.wikipedia.org/wiki/GloVe_(machine_learning)[GLoVE], and https://en.wikipedia.org/wiki/BERT_(language_model)[BERT], or OpenAI's `text-embedding-ada-002`, are used to convert words, sentences, or paragraphs into these vector embeddings.\n\nThe vector database's role is to store and facilitate similarity searches for these embeddings. It does not generate the embeddings itself. For creating vector embeddings, the `EmbeddingModel` should be utilized.\n\nThe `similaritySearch` methods in the interface allow for retrieving documents similar to a given query string. These methods can be fine-tuned by using the following parameters:\n\n* `k`: An integer that specifies the maximum number of similar documents to return. This is often referred to as a 'top K' search, or 'K nearest neighbors' (KNN).\n* `threshold`: A double value ranging from 0 to 1, where values closer to 1 indicate higher similarity. By default, if you set a threshold of 0.75, for instance, only documents with a similarity above this value are returned.\n* `Filter.Expression`: A class used for passing a fluent DSL (Domain-Specific Language) expression that functions similarly to a 'where' clause in SQL, but it applies exclusively to the metadata key-value pairs of a `Document`.\n* `filterExpression`: An external DSL based on ANTLR4 that accepts filter expressions as strings. For example, with metadata keys like country, year, and `isActive`, you could use an expression such as: `country == 'UK' && year >= 2020 && isActive == true.`\n\nFind more information on the `Filter.Expression` in the <<metadata-filters>> section.\n\n== Schema Initialization\n\nSome vector stores require their backend schema to be initialized before usage.\nIt will not be initialized for you by default.\nYou must opt-in, by passing a `boolean` for the appropriate constructor argument or, if using Spring Boot, setting the appropriate `initialize-schema` property to `true` in `application.properties` or `application.yml`.\nCheck the documentation for the vector store you are using for the specific property name.\n\n== Batching Strategy\n\nWhen working with vector stores, it's often necessary to embed large numbers of documents.\nWhile it might seem straightforward to make a single call to embed all documents at once, this approach can lead to issues.\nEmbedding models process text as tokens and have a maximum token limit, often referred to as the context window size.\nThis limit restricts the amount of text that can be processed in a single embedding request.\nAttempting to embed too many tokens in one call can result in errors or truncated embeddings.\n\nTo address this token limit, Spring AI implements a batching strategy.\nThis approach breaks down large sets of documents into smaller batches that fit within the embedding model's maximum context window.\nBatching not only solves the token limit issue but can also lead to improved performance and more efficient use of API rate limits.\n\nSpring AI provides this functionality through the `BatchingStrategy` interface, which allows for processing documents in sub-batches based on their token counts.\n\nThe core `BatchingStrategy` interface is defined as follows:\n\n[source,java]\n----\npublic interface BatchingStrategy {\n    List<List<Document>> batch(List<Document> documents);\n}\n----\n\nThis interface defines a single method, `batch`, which takes a list of documents and returns a list of document batches.\n\n=== Default Implementation\n\nSpring AI provides a default implementation called `TokenCountBatchingStrategy`.\nThis strategy batches documents based on their token counts, ensuring that each batch does not exceed a calculated maximum input token count.\n\nKey features of `TokenCountBatchingStrategy`:\n\n1. Uses https://platform.openai.com/docs/guides/embeddings/embedding-models[OpenAI's max input token count] (8191) as the default upper limit.\n2. Incorporates a reserve percentage (default 10%) to provide a buffer for potential overhead.\n3. Calculates the actual max input token count as: `actualMaxInputTokenCount = originalMaxInputTokenCount * (1 - RESERVE_PERCENTAGE)`\n\nThe strategy estimates the token count for each document, groups them into batches without exceeding the max input token count, and throws an exception if a single document exceeds this limit.\n\nYou can also customize the `TokenCountBatchingStrategy` to better suit your specific requirements. This can be done by creating a new instance with custom parameters in a Spring Boot `@Configuration` class.\n\nHere's an example of how to create a custom `TokenCountBatchingStrategy` bean:\n\n[source,java]\n----\n@Configuration\npublic class EmbeddingConfig {\n    @Bean\n    public BatchingStrategy customTokenCountBatchingStrategy() {\n        return new TokenCountBatchingStrategy(\n            EncodingType.CL100K_BASE,  // Specify the encoding type\n            8000,                      // Set the maximum input token count\n            0.1                        // Set the reserve percentage\n        );\n    }\n}\n----\n\nIn this configuration:\n\n1. `EncodingType.CL100K_BASE`: Specifies the encoding type used for tokenization. This encoding type is used by the `JTokkitTokenCountEstimator` to accurately estimate token counts.\n2. `8000`: Sets the maximum input token count. This value should be less than or equal to the maximum context window size of your embedding model.\n3. `0.1`: Sets the reserve percentage. The percentage of tokens to reserve from the max input token count. This creates a buffer for potential token count increases during processing.\n\nBy default, this constructor uses `Document.DEFAULT_CONTENT_FORMATTER` for content formatting and `MetadataMode.NONE` for metadata handling. If you need to customize these parameters, you can use the full constructor with additional parameters.\n\nOnce defined, this custom `TokenCountBatchingStrategy` bean will be automatically used by the `EmbeddingModel` implementations in your application, replacing the default strategy.\n\nThe `TokenCountBatchingStrategy` internally uses a `TokenCountEstimator` (specifically, `JTokkitTokenCountEstimator`) to calculate token counts for efficient batching. This ensures accurate token estimation based on the specified encoding type.\n\n\nAdditionally, `TokenCountBatchingStrategy` provides flexibility by allowing you to pass in your own implementation of the `TokenCountEstimator` interface. This feature enables you to use custom token counting strategies tailored to your specific needs. For example:\n\n[source,java]\n----\nTokenCountEstimator customEstimator = new YourCustomTokenCountEstimator();\nTokenCountBatchingStrategy strategy = new TokenCountBatchingStrategy(\n\t\tthis.customEstimator,\n    8000,  // maxInputTokenCount\n    0.1,   // reservePercentage\n    Document.DEFAULT_CONTENT_FORMATTER,\n    MetadataMode.NONE\n);\n----\n\n=== Working with Auto-Truncation\n\nSome embedding models, such as Vertex AI text embedding, support an `auto_truncate` feature. When enabled, the model silently truncates text inputs that exceed the maximum size and continues processing; when disabled, it throws an explicit error for inputs that are too large.\n\nWhen using auto-truncation with the batching strategy, you must configure your batching strategy with a much higher input token count than the model's actual maximum. This prevents the batching strategy from raising exceptions for large documents, allowing the embedding model to handle truncation internally.\n\n==== Configuration for Auto-Truncation\n\nWhen enabling auto-truncation, set your batching strategy's maximum input token count much higher than the model's actual limit. This prevents the batching strategy from raising exceptions for large documents, allowing the embedding model to handle truncation internally.\n\nHere's an example configuration for using Vertex AI with auto-truncation and custom `BatchingStrategy` and then using them in the PgVectorStore:\n\n[source,java]\n----\n@Configuration\npublic class AutoTruncationEmbeddingConfig {\n\n    @Bean\n    public VertexAiTextEmbeddingModel vertexAiEmbeddingModel(\n            VertexAiEmbeddingConnectionDetails connectionDetails) {\n\n        VertexAiTextEmbeddingOptions options = VertexAiTextEmbeddingOptions.builder()\n                .model(VertexAiTextEmbeddingOptions.DEFAULT_MODEL_NAME)\n                .autoTruncate(true)  // Enable auto-truncation\n                .build();\n\n        return new VertexAiTextEmbeddingModel(connectionDetails, options);\n    }\n\n    @Bean\n    public BatchingStrategy batchingStrategy() {\n        // Only use a high token limit if auto-truncation is enabled in your embedding model.\n        // Set a much higher token count than the model actually supports\n        // (e.g., 132,900 when Vertex AI supports only up to 20,000)\n        return new TokenCountBatchingStrategy(\n                EncodingType.CL100K_BASE,\n                132900,  // Artificially high limit\n                0.1      // 10% reserve\n        );\n    }\n\n    @Bean\n    public VectorStore vectorStore(JdbcTemplate jdbcTemplate, EmbeddingModel embeddingModel, BatchingStrategy batchingStrategy) {\n        return PgVectorStore.builder(jdbcTemplate, embeddingModel)\n            // other properties omitted here\n            .build();\n    }\n}\n----\n\nIn this configuration:\n\n1. The embedding model has auto-truncation enabled, allowing it to handle oversized inputs gracefully.\n2. The batching strategy uses an artificially high token limit (132,900) that's much larger than the actual model limit (20,000).\n3. The vector store uses the configured embedding model and the custom `BatchingStrategy` bean.\n\n==== Why This Works\n\nThis approach works because:\n\n1. The `TokenCountBatchingStrategy` checks if any single document exceeds the configured maximum and throws an `IllegalArgumentException` if it does.\n2. By setting a very high limit in the batching strategy, we ensure that this check never fails.\n3. Documents or batches exceeding the model's limit are silently truncated and processed by the embedding model's auto-truncation feature.\n\n==== Best Practices\n\nWhen using auto-truncation:\n\n- Set the batching strategy's max input token count to be at least 5-10x larger than the model's actual limit to avoid premature exceptions from the batching strategy.\n- Monitor your logs for truncation warnings from the embedding model (note: not all models log truncation events).\n- Consider the implications of silent truncation on your embedding quality.\n- Test with sample documents to ensure truncated embeddings still meet your requirements.\n- Document this configuration for future maintainers, as it is non-standard.\n\nCAUTION: While auto-truncation prevents errors, it can result in incomplete embeddings. Important information at the end of long documents may be lost. If your application requires all content to be embedded, split documents into smaller chunks before embedding.\n\n==== Spring Boot Auto-Configuration\n\nIf you're using Spring Boot auto-configuration, you must provide a custom `BatchingStrategy` bean to override the default one that comes with Spring AI:\n\n[source,java]\n----\n@Bean\npublic BatchingStrategy customBatchingStrategy() {\n    // This bean will override the default BatchingStrategy\n    return new TokenCountBatchingStrategy(\n            EncodingType.CL100K_BASE,\n            132900,  // Much higher than model's actual limit\n            0.1\n    );\n}\n----\n\nThe presence of this bean in your application context will automatically replace the default batching strategy used by all vector stores.\n\n=== Custom Implementation\n\nWhile `TokenCountBatchingStrategy` provides a robust default implementation, you can customize the batching strategy to fit your specific needs.\nThis can be done through Spring Boot's auto-configuration.\n\nTo customize the batching strategy, define a `BatchingStrategy` bean in your Spring Boot application:\n\n[source,java]\n----\n@Configuration\npublic class EmbeddingConfig {\n    @Bean\n    public BatchingStrategy customBatchingStrategy() {\n        return new CustomBatchingStrategy();\n    }\n}\n----\n\nThis custom `BatchingStrategy` will then be automatically used by the `EmbeddingModel` implementations in your application.\n\nNOTE: Vector stores supported by Spring AI are configured to use the default `TokenCountBatchingStrategy`.\nSAP Hana vector store is not currently configured for batching.\n\n== VectorStore Implementations\n\nThese are the available implementations of the `VectorStore` interface:\n\n* xref:api/vectordbs/azure.adoc[Azure Vector Search] -

A simple implementation of a vector storage, good only for testing purposes. \n\nWARNING: The `SimpleVectorStore` implementation is not designed for production use and should only be used for testing or demonstration purposes.\n\nMore implementations may be supported in future releases.\n\nIf you have a vector database that needs to be supported by Spring AI, open an issue on GitHub or, even better, submit a pull request with an implementation.\n\nInformation on each of the `VectorStore` implementations can be found in the subsections of this chapter.\n\n== Example Usage\n\nTo compute the embeddings for a vector database, you need to pick an embedding model that matches the higher-level AI model being used.\n\nFor example, with OpenAI's ChatGPT, we use the `OpenAiEmbeddingModel` and a model named `text-embedding-ada-002`.\n\nThe Spring Boot starter's auto-configuration for OpenAI makes an implementation of `EmbeddingModel` available in the Spring application context for dependency injection.\n\n=== Writing to a Vector Store\n\nThe general usage of loading data into a vector store is something you would do in a batch-like job, by first loading data into Spring AI's `Document` class and then calling the `add` method on the `VectorStore` interface.\n\nGiven a `String` reference to a source file that represents a JSON file with data we want to load into the vector database, we use Spring AI's `JsonReader` to load specific fields in the JSON, which splits them up into small pieces and then passes those small pieces to the vector store implementation.\nThe `VectorStore` implementation computes the embeddings and stores the JSON and the embedding in the vector database:\n\n[source,java]\n----\n@Autowired\nVectorStore vectorStore;\n\nvoid load(String sourceFile) {\n    JsonReader jsonReader = new JsonReader(new FileSystemResource(sourceFile),\n            \"price\", \"name\", \"shortDescription\", \"description\", \"tags\");\n    List<Document> documents = jsonReader.get();\n    this.vectorStore.add(documents);\n}\n----\n\n=== Reading from a Vector Store\n\nLater, when a user question is passed into the AI model, a similarity search is done to retrieve similar documents, which are then \"stuffed\" into the prompt as context for the user's question.\n\nFor read-only operations, you can use either the `VectorStore` interface or the more focused `VectorStoreRetriever` interface:\n\n[source,java]\n----\n@Autowired\nVectorStoreRetriever retriever; // Could also use VectorStore here\n\nString question = \"<question from user>\";\nList<Document> similarDocuments = retriever.similaritySearch(question);\n\n// Or with more specific search parameters\nSearchRequest request = SearchRequest.builder()\n    .query(question)\n    .topK(5)                       // Return top 5 results\n    .similarityThreshold(0.7)      // Only return results with similarity score >= 0.7\n    .build();\n\nList<Document> filteredDocuments = retriever.similaritySearch(request);\n----\n\nAdditional options can be passed into the `similaritySearch` method to define how many documents to retrieve and a threshold of the similarity search.\n\n=== Separation of Read and Write Operations\n\nUsing the separate interfaces allows you to clearly define which components need write access and which only need read access:\n\n[source,java]\n----\n// Write operations in a service that needs full access\n@Service\nclass DocumentIndexer {\n    private final VectorStore vectorStore;\n\n    DocumentIndexer(VectorStore vectorStore) {\n        this.vectorStore = vectorStore;\n    }\n\n    public void indexDocuments(List<Document> documents) {\n        vectorStore.add(documents);\n    }\n}\n\n// Read-only operations in a service that only needs retrieval\n@Service\nclass DocumentRetriever {\n    private final VectorStoreRetriever retriever;\n\n    DocumentRetriever(VectorStoreRetriever retriever) {\n        this.retriever = retriever;\n    }\n\n    public List<Document> findSimilar(String query) {\n        return retriever.similaritySearch(query);\n    }\n}\n----\n\nThis separation of concerns helps create more maintainable and secure applications by limiting access to mutation operations only to components that truly need them.\n\n== Retrieval Operations with VectorStoreRetriever\n\nThe `VectorStoreRetriever` interface provides a read-only view of a vector store, exposing only the similarity search functionality. This follows the principle of least privilege and is particularly useful in RAG (Retrieval-Augmented Generation) applications where you only need to retrieve documents without modifying the underlying data.\n\n=== Benefits of Using VectorStoreRetriever\n\n1. **Separation of Concerns**: Clearly separates read operations from write operations.\n2. **Interface Segregation**: Clients that only need retrieval functionality aren't exposed to mutation methods.\n3. **Functional Interface**: Can be implemented with lambda expressions or method references for simple use cases.\n4. **Reduced Dependencies**: Components that only need to perform searches don't need to depend on the full `VectorStore` interface.\n\n=== Example Usage\n\nYou can use `VectorStoreRetriever` directly when you only need to perform similarity searches:\n\n[source,java]\n----\n@Service\npublic class DocumentRetrievalService {\n\n    private final VectorStoreRetriever retriever;\n\n    public DocumentRetrievalService(VectorStoreRetriever retriever) {\n        this.retriever = retriever;\n    }\n\n    public List<Document> findSimilarDocuments(String query) {\n        return retriever.similaritySearch(query);\n    }\n\n    public List<Document> findSimilarDocumentsWithFilters(String query, String country) {\n        SearchRequest request = SearchRequest.builder()\n            .query(query)\n            .topK(5)\n            .filterExpression(\"country == '\" + country + \"'\")\n            .build();\n\n        return retriever.similaritySearch(request);\n    }\n}\n----\n\nIn this example, the service only depends on the `VectorStoreRetriever` interface, making it clear that it only performs retrieval operations and doesn't modify the vector store.\n\n=== Integration with RAG Applications\n\nThe `VectorStoreRetriever` interface is particularly useful in RAG applications, where you need to retrieve relevant documents to provide context for an AI model:\n\n[source,java]\n----\n@Service\npublic class RagService {\n\n    private final VectorStoreRetriever retriever;\n    private final ChatModel chatModel;\n\n    public RagService(VectorStoreRetriever retriever, ChatModel chatModel) {\n        this.retriever = retriever;\n        this.chatModel = chatModel;\n    }\n\n    public String generateResponse(String userQuery) {\n        // Retrieve relevant documents\n        List<Document> relevantDocs = retriever.similaritySearch(userQuery);\n\n        // Extract content from documents to use as context\n        String context = relevantDocs.stream()\n            .map(Document::getContent)\n            .collect(Collectors.joining(\"\\n\\n\"));\n\n        // Generate response using the retrieved context\n        String prompt = \"Context information:\\n\" + context + \"\\n\\nUser query: \" + userQuery;\n        return chatModel.generate(prompt);\n    }\n}\n----\n\nThis pattern allows for a clean separation between the retrieval component and the generation component in RAG applications.\n\n== Metadata Filters [[metadata-filters]]\n\nThis section describes various filters that you can use against the results of a query.\n\n=== Filter String\nYou can pass in an SQL-like filter expressions as a `String` to one of the `similaritySearch` overloads.\n\nConsider the following examples:\n\n* `\"country == 'BG'\"`\n* `\"genre == 'drama' && year >= 2020\"`\n* `\"genre in ['comedy', 'documentary', 'drama']\"`\n\n=== Filter.Expression\n\nYou can create an instance of `Filter.Expression` with a `FilterExpressionBuilder` that exposes a fluent API.\nA simple example is as follows:\n\n[source, java]\n----\nFilterExpressionBuilder b = new FilterExpressionBuilder();\nExpression expression = this.b.eq(\"country\", \"BG\").build();\n----\n\nYou can build up sophisticated expressions by using the following operators:\n\n[source, text]\n----\nEQUALS: '=='\nMINUS : '-'\nPLUS: '+'\nGT: '>'\nGE: '>='\nLT: '<'\nLE: '<='\nNE: '!='\n----\n\nYou can combine expressions by using the following operators:\n\n[source,text]\n----\nAND: 'AND' | 'and' | '&&';\nOR: 'OR' | 'or' | '||';\n----\n\nConsidering the following example:\n\n[source,java]\n----\nExpression exp = b.and(b.eq(\"genre\", \"drama\"), b.gte(\"year\", 2020)).build();\n----\n\nYou can also use the following operators:\n\n[source,text]\n----\nIN: 'IN' | 'in';\nNIN: 'NIN' | 'nin';\nNOT: 'NOT' | 'not';\n----\n\nConsider the following example:\n\n[source,java]\n----\nExpression exp = b.and(b.in(\"genre\", \"drama\", \"documentary\"), b.not(b.lt(\"year\", 2020))).build();\n----\n\nYou can also use the following operators:\n\n[source,text]\n----\nIS: 'IS' | 'is';\nNULL: 'NULL' | 'null';\nNOT NULL: 'NOT NULL' | 'not null';\n----\n\nConsider the following example:\n\n[source,java]\n----\nExpression exp = b.and(b.isNull(\"year\")).build();\nExpression exp = b.and(b.isNotNull(\"year\")).build();\n----\n\nNOTE: `IS NULL` and `IS NOT NULL` have not been implemented in all vector stores yet.\n\n== Deleting Documents from Vector Store\n\nThe Vector Store interface provides multiple methods for deleting documents, allowing you to remove data either by specific document IDs or using filter expressions.\n\n=== Delete by Document IDs\n\nThe simplest way to delete documents is by providing a list of document IDs:\n\n[source,java]\n----\nvoid delete(List<String> idList);\n----\n\nThis method removes all documents whose IDs match those in the provided list.\nIf any ID in the list doesn't exist in the store, it will be ignored.\n\n.Example usage\n[source,java]\n----\n// Create and add document\nDocument document = new Document(\"The World is Big\",\n    Map.of(\"country\", \"Netherlands\"));\nvectorStore.add(List.of(document));\n\n// Delete document by ID\nvectorStore.delete(List.of(document.getId()));\n----\n\n=== Delete by Filter Expression\n\nFor more complex deletion criteria, you can use filter expressions:\n\n[source,java]\n----\nvoid delete(Filter.Expression filterExpression);\n----\n\nThis method accepts a `Filter.Expression` object that defines the criteria for which documents should be deleted.\nIt's particularly useful when you need to delete documents based on their metadata properties.\n\n.Example usage\n[source,java]\n----\n// Create test documents with different metadata\nDocument bgDocument = new Document(\"The World is Big\",\n    Map.of(\"country\", \"Bulgaria\"));\nDocument nlDocument = new Document(\"The World is Big\",\n    Map.of(\"country\", \"Netherlands\"));\n\n// Add documents to the store\nvectorStore.add(List.of(bgDocument, nlDocument));\n\n// Delete documents from Bulgaria using filter expression\nFilter.Expression filterExpression = new Filter.Expression(\n    Filter.ExpressionType.EQ,\n    new Filter.Key(\"country\"),\n    new Filter.Value(\"Bulgaria\")\n);\nvectorStore.delete(filterExpression);\n\n// Verify deletion with search\nSearchRequest request = SearchRequest.builder()\n    .query(\"World\")\n    .filterExpression(\"country == 'Bulgaria'\")\n    .build();\nList<Document> results = vectorStore.similaritySearch(request);\n// results will be empty as Bulgarian document was deleted\n----\n\n=== Delete by String Filter Expression\n\nFor convenience, you can also delete documents using a string-based filter expression:\n\n[source,java]\n----\nvoid delete(String filterExpression);\n----\n\nThis method converts the provided string filter into a `Filter.Expression` object internally.\nIt's useful when you have filter criteria in string format.\n\n.Example usage\n[source,java]\n----\n// Create and add documents\nDocument bgDocument = new Document(\"The World is Big\",\n    Map.of(\"country\", \"Bulgaria\"));\nDocument nlDocument = new Document(\"The World is Big\",\n    Map.of(\"country\", \"Netherlands\"));\nvectorStore.add(List.of(bgDocument, nlDocument));\n\n// Delete Bulgarian documents using string filter\nvectorStore.delete(\"country == 'Bulgaria'\");\n\n// Verify remaining documents\nSearchRequest request = SearchRequest.builder()\n    .query(\"World\")\n    .topK(5)\n    .build();\nList<Document> results = vectorStore.similaritySearch(request);\n// results will only contain the Netherlands document\n----\n\n=== Error Handling When Calling the Delete API\n\nAll deletion methods may throw exceptions in case of errors:\n\nThe best practice is to wrap delete operations in try-catch blocks:\n\n.Example usage\n[source,java]\n----\ntry {\n    vectorStore.delete(\"country == 'Bulgaria'\");\n}\ncatch (Exception  e) {\n    logger.error(\"Invalid filter expression\", e);\n}\n----\n\n=== Document Versioning Use Case\n\nA common scenario is managing document versions where you need to upload a new version of a document while removing the old version. Here's how to handle this using filter expressions:\n\n.Example usage\n[source,java]\n----\n// Create initial document (v1) with version metadata\nDocument documentV1 = new Document(\n    \"AI and Machine Learning Best Practices\",\n    Map.of(\n        \"docId\", \"AIML-001\",\n        \"version\", \"1.0\",\n        \"lastUpdated\", \"2024-01-01\"\n    )\n);\n\n// Add v1 to the vector store\nvectorStore.add(List.of(documentV1));\n\n// Create updated version (v2) of the same document\nDocument documentV2 = new Document(\n    \"AI and Machine Learning Best Practices - Updated\",\n    Map.of(\n        \"docId\", \"AIML-001\",\n        \"version\", \"2.0\",\n        \"lastUpdated\", \"2024-02-01\"\n    )\n);\n\n// First, delete the old version using filter expression\nFilter.Expression deleteOldVersion = new Filter.Expression(\n    Filter.ExpressionType.AND,\n    new Filter.Expression(\n        Filter.ExpressionType.EQ,\n        new Filter.Key(\"docId\"),\n        new Filter.Value(\"AIML-001\")\n    ),\n    new Filter.Expression(\n        Filter.ExpressionType.EQ,\n        new Filter.Key(\"version\"),\n        new Filter.Value(\"1.0\")\n    )\n);\nvectorStore.delete(deleteOldVersion);\n\n// Add the new version\nvectorStore.add(List.of(documentV2));\n\n// Verify only v2 exists\nSearchRequest request = SearchRequest.builder()\n    .query(\"AI and Machine Learning\")\n    .filterExpression(\"docId == 'AIML-001'\")\n    .build();\nList<Document> results = vectorStore.similaritySearch(request);\n// results will contain only v2 of the document\n----\n\nYou can also accomplish the same using the string filter expression:\n\n.Example usage\n[source,java]\n----\n// Delete old version using string filter\nvectorStore.delete(\"docId == 'AIML-001' AND version == '1.0'\");\n\n// Add new version\nvectorStore.add(List.of(documentV2));\n----\n\n=== Performance Considerations While Deleting Documents\n\n* Deleting by ID list is generally faster when you know exactly which documents to remove.\n* Filter-based deletion may require scanning the index to find matching documents; however, this is vector store implementation-specific.\n* Large deletion operations should be batched to avoid overwhelming the system.\n* Consider using filter expressions when deleting based on document properties rather than collecting IDs first.\n\n== Understanding Vectors\n\nxref:api/vectordbs/understand-vectordbs.adoc[Understanding Vectors]\n"

    "content": "[[concepts]]\n= AI Concepts\n\nThis section describes core concepts that Spring AI uses. We recommend reading it closely to understand the ideas behind how Spring AI is implemented.\n\n== Models\n\nAI models are algorithms designed to process and generate information, often mimicking human cognitive functions.\nBy learning patterns and insights from large datasets, these models can make predictions, text, images, or other outputs, enhancing various applications across industries.\n\nThere are many different types of AI models, each suited for a specific use case.\nWhile ChatGPT and its generative AI capabilities have captivated users through text input and output, many models and companies offer diverse inputs and outputs.\nBefore ChatGPT, many people were fascinated by text-to-image generation models such as Midjourney and Stable Diffusion.\n\nThe following table categorizes several models based on their input and output types:\n\nimage::spring-ai-concepts-model-types.jpg[Model types, width=600, align=\"center\"]\n\nSpring AI currently supports models that process input and output as language, image, and audio.\nThe last row in the previous table, which accepts text as input and outputs numbers, is more commonly known as embedding text and represents the internal data structures used in an AI model.\nSpring AI has support for embeddings to enable more advanced use cases.\n\nWhat sets models like GPT apart is their pre-trained nature, as indicated by the \"P\" in GPT—Chat Generative Pre-trained Transformer.\nThis pre-training feature transforms AI into a general developer tool that does not require an extensive machine learning or model training background.\n\n== Prompts\n\nPrompts serve as the foundation for the language-based inputs that guide an AI model to produce specific outputs.\nFor those familiar with ChatGPT, a prompt might seem like merely the text entered into a dialog box that is sent to the API.\nHowever, it encompasses much more than that.\nIn many AI Models, the text for the prompt is not just a simple string.\n\nChatGPT's API has multiple text inputs within a prompt, with each text input being assigned a role.\nFor example, there is the system role, which tells the model how to behave and sets the context for the interaction.\nThere is also the user role, which is typically the input from the user.\n\nCrafting effective prompts is both an art and a science.\nChatGPT was designed for human conversations.\nThis is quite a departure from using something like SQL to \"ask a question\".\nOne must communicate with the AI model akin to conversing with another person.\n\nSuch is the importance of this interaction style that the term \"Prompt Engineering\" has emerged as its own discipline.\nThere is a burgeoning collection of techniques that improve the effectiveness of prompts.\nInvesting time in crafting a prompt can drastically improve the resulting output.\n\nSharing prompts has become a communal practice, and there is active academic research being done on this subject.\nAs an example of how counter-intuitive it can be to create an effective prompt (for example, contrasting with SQL), a https://arxiv.org/abs/2205.11916[recent research paper] found that one of the most effective prompts you can use starts with the phrase, \"`Take a deep breath and work on this step by step.`\"\nThat should give you an indication of why language is so important.\nWe do not yet fully understand how to make the most effective use of previous iterations of this technology, such as ChatGPT 3.5, let alone new versions that are being developed.\n\n=== Prompt Templates\n\nCreating effective prompts involves establishing the context of the request and substituting parts of the request with values specific to the user's input.\n\nThis process uses traditional text-based template engines for prompt creation and management.\nSpring AI employs the OSS library https://www.stringtemplate.org/[StringTemplate] for this purpose.\n\nFor instance, consider the simple prompt template:\n\n```\nTell me a {adjective} joke about {content}.\n```\n\nIn Spring AI, prompt templates can be likened to the \"View\" in Spring MVC architecture.\nA model object, typically a `java.util.Map`, is provided to populate placeholders within the template.\nThe \"rendered\" string becomes the content of the prompt supplied to the AI model.\n\nThere is considerable variability in the specific data format of the prompt sent to the model.\nInitially starting as simple strings, prompts have evolved to include multiple messages, where each string in each message represents a distinct role for the model.\n\n== Embeddings\n\nEmbeddings are numerical representations of text, images, or videos that capture relationships between inputs.\n\nEmbeddings work by converting text, image, and video into arrays of floating point numbers, called vectors.\nThese vectors are designed to capture the meaning of the text, images, and videos.\nThe length of the embedding array is called the vector's dimensionality.\n\nBy calculating the numerical distance between the vector representations of two pieces of text, an application can determine the similarity between the objects used to generate the embedding vectors.\n\nimage::spring-ai-embeddings.jpg[Embeddings, width=900, align=\"center\"]\n\nAs a Java developer exploring AI, it's not necessary to comprehend the intricate mathematical theories or the specific implementations behind these vector representations.\nA basic understanding of their role and function within AI systems suffices, particularly when you're integrating AI functionalities into your applications.\n\nEmbeddings are particularly relevant in practical applications like the Retrieval Augmented Generation (RAG) pattern.\nThey enable the representation of data as points in a semantic space, which is akin to the 2-D space of Euclidean geometry, but in higher dimensions.\nThis means just like how points on a plane in Euclidean geometry can be close or far based on their coordinates, in a semantic space, the proximity of points reflects the similarity in meaning.\nSentences about similar topics are positioned closer in this multi-dimensional space, much like points lying close to each other on a graph.\nThis proximity aids in tasks like text classification, semantic search, and even product recommendations, as it allows the AI to discern and group related concepts based on their \"location\" in this expanded semantic landscape.\n\nYou can think of this semantic space as a vector.\n\n== Tokens\n\nTokens serve as the building blocks of how an AI model works.\nOn input, models convert words to tokens. On output, they convert tokens back to words.\n\nIn English, one token roughly corresponds to 75% of a word. For reference, Shakespeare's complete works, totaling around 900,000 words, translate to approximately 1.2 million tokens.\n\nimage::spring-ai-concepts-tokens.png[Tokens, width=600, align=\"center\"]\n\nPerhaps more important is that Tokens = Money.\nIn the context of hosted AI models, your charges are determined by the number of tokens used. Both input and output contribute to the overall token count.\n\nAlso, models are subject to token limits, which restrict the amount of text processed in a single API call.\nThis threshold is often referred to as the \"context window\". The model does not process any text that exceeds this limit.\n\nFor instance, ChatGPT3 has a 4K token limit, while GPT4 offers varying options, such as 8K, 16K, and 32K.\nAnthropic's Claude AI model features a 100K token limit, and Meta's recent research yielded a 1M token limit model.\n\nTo summarize the collected works of Shakespeare with GPT4, you need to devise software engineering strategies to chop up the data and present the data within the model's context window limits.\nThe Spring AI project helps you with this task.\n\n== Structured Output\n\nThe output of AI models traditionally arrives as a `java.lang.String`, even if you ask for the reply to be in JSON.\nIt may be a correct JSON, but it is not a JSON data structure. It is just a string.\nAlso, asking \"`for JSON`\" as part of the prompt is not 100% accurate.\n\nThis intricacy has led to the emergence of a specialized field involving the creation of prompts to yield the intended output, followed by converting the resulting simple string into a usable data structure for application integration.\n\nimage::structured-output-architecture.jpg[Structured Output Converter Architecture, width=800, align=\"center\"]\n\nThe xref:api/structured-output-converter.adoc#_structuredoutputconverter[Structured output conversion] employs meticulously crafted prompts, often necessitating multiple interactions with the model to achieve the desired formatting.\n\n== Bringing Your Data & APIs to the AI Model\n\nHow can you equip the AI model with information on which it has not been trained?\n\nNote that the GPT 3.5/4.0 dataset extends only until September 2021.\nConsequently, the model says that it does not know the answer to questions that require knowledge beyond that date.\nAn interesting bit of trivia is that this dataset is around 650GB.\n\nThree techniques exist for customizing the AI model to incorporate your data:\n\n* **Fine Tuning**: This traditional machine learning technique involves tailoring the model and changing its internal weighting.\nHowever, it is a challenging process for machine learning experts and extremely resource-intensive for models like GPT due to their size. Additionally, some models might not offer this option.\n\n* **Prompt Stuffing**: A more practical alternative involves embedding your data within the prompt provided to the model. Given a model's token limits, techniques are required to present relevant data within the model's context window.\nThis approach is colloquially referred to as \"`stuffing the prompt.`\"\nThe Spring AI library helps you implement solutions based on the \"`stuffing the prompt`\" technique otherwise known as xref::concepts.adoc#concept-rag[Retrieval Augmented Generation (RAG)].\n\nimage::spring-ai-prompt-stuffing.jpg[Prompt stuffing, width=700, align=\"center\"]\n\n* **xref::concepts.adoc#concept-fc[Tool Calling]**: This technique allows registering tools (user-defined services) that connect the large language models to the APIs of external systems.\nSpring AI greatly simplifies code you need to write to support xref:api/tools.adoc[tool calling].\n\n[[concept-rag]]\n=== Retrieval Augmented Generation\n\nA technique termed Retrieval Augmented Generation (RAG) has emerged to address the challenge of incorporating relevant data into prompts for accurate AI model responses.\n\nThe approach involves a batch processing style programming model, where the job reads unstructured data from your documents, transforms it, and then writes it into a vector database.\nAt a high level, this is an ETL (Extract, Transform and Load) pipeline.\nThe vector database is used in the retrieval part of RAG technique.\n\nAs part of loading the unstructured data into the vector database, one of the most important transformations is to split the original document into smaller pieces.\nThe procedure of splitting the original document into smaller pieces has two important steps:\n\n. Split the document into parts while preserving the semantic boundaries of the content.\nFor example, for a document with paragraphs and tables, one should avoid splitting the document in the middle of a paragraph or table.\nFor code, avoid splitting the code in the middle of a method's implementation.\n. Split the document's parts further into parts whose size is a small percentage of the AI Model's token limit.\n\nThe next phase in RAG is processing user input.\nWhen a user's question is to be answered by an AI model, the question and all the \"`similar`\" document pieces are placed into the prompt that is sent to the AI model.\nThis is the reason to use a vector database. It is very good at finding similar content.\n\nimage::spring-ai-rag.jpg[Spring AI RAG, width=1000, align=\"center\"]\n\n* The xref::api/etl-pipeline.adoc[ETL Pipeline] provides further information about orchestrating the flow of extracting data from data sources and storing it in a structured vector store, ensuring data is in the optimal format for retrieval when passing it to the AI model.\n* The xref::api/chatclient.adoc#_retrieval_augmented_generation[ChatClient - RAG] explains how to use the `QuestionAnswerAdvisor` to enable the RAG capability in your application.\n\n[[concept-fc]]\n=== Tool Calling\n\nLarge Language Models (LLMs) are frozen after training, leading to stale knowledge, and they are unable to access or modify external data.\n\nThe xref::api/tools.adoc[Tool Calling] mechanism addresses these shortcomings.\nIt allows you to register your own services as tools to connect the large language models to the APIs of external systems.\nThese systems can provide LLMs with real-time data and perform data processing actions on their behalf.\n\nSpring AI greatly simplifies code you need to write to support tool invocation.\nIt handles the tool invocation conversation for you.\nYou can provide your tool as a `@Tool`-annotated method and provide it in your prompt options to make it available to the model.\nAdditionally, you can define and reference multiple tools in a single prompt.\n\nimage::tools/tool-calling-01.jpg[The main sequence of actions for tool calling, width=700, align=\"center\"]\n\n1. When we want to make a tool available to the model, we include its definition in the chat request. Each tool definition comprises of a name, a description, and the schema of the input parameters.\n2. When the model decides to call a tool, it sends a response with the tool name and the input parameters modeled after the defined schema.\n3. The application is responsible for using the tool name to identify and execute the tool with the provided input parameters.\n4. The result of the tool call is processed by the application.\n5. The application sends the tool call result back to the model.\n6. The model generates the final response using the tool call result as additional context.\n\nFollow the xref::api/tools.adoc[Tool Calling] documentation for further information on how to use this feature with different AI models.\n\n[[concept-evaluating-ai-responses]]\n== Evaluating AI responses\n\nEffectively evaluating the output of an AI system in response to user requests is very important to ensuring the accuracy and usefulness of the final application.\nSeveral emerging techniques enable the use of the pre-trained model itself for this purpose.\n\nThis evaluation process involves analyzing whether the generated response aligns with the user's intent and the context of the query. Metrics such as relevance, coherence, and factual correctness are used to gauge the quality of the AI-generated response.\n\nOne approach involves presenting both the user's request and the AI model's response to the model, querying whether the response aligns with the provided data.\n\nFurthermore, leveraging the information stored in the vector database as supplementary data can enhance the evaluation process, aiding in the determination of response relevance.\n\nThe Spring AI project provides an `Evaluator` API which currently gives access to basic strategies to evaluate model responses.\nFollow the xref::api/testing.adoc[Evaluation Testing] documentation for further information.\n"

This often involves utilizing the\n`RestClient` class from the Spring Framework, similar to the `OpenAiApi` class.\n\n. *Create a Model implementation*\nEnsure your client conforms to the link:https://docs.spring.io/spring-ai/reference/api/generic-model.html[Generic Model API].\nUse existing request and response classes if your model's inputs and outputs are supported.\nIf not, create new classes for the Generic Model API and establish a new Java package.\nWhen logging Personally Identifiable Information (PII), mark it with https://github.com/spring-projects/spring-ai/tree/main/spring-ai-core/src/main/java/org/springframework/ai/util/LoggingMarkers.java[`PII_MARKER`] Slf4j marker.\n\n. *Implement Auto-Configuration and a Spring Boot Starter*: This step involves creating the\nnecessary auto-configuration and Spring Boot Starter to easily instantiate the new model with\nSpring Boot applications.\n\n. *Write Tests*: All new classes should be accompanied by comprehensive tests.\nExisting tests can serve as a useful reference for structuring and implementing your tests.\n\n. *Document Your Contribution*: Ensure your documentation follows the existing format,\nFor an example of the suggested structure and formatting, refer to the\nlink:https://docs.spring.io/spring-ai/reference/api/chat/openai-chat.html[Open AI Chat documentation].\n\nBy following these guidelines, we can greatly expand the framework's range of supported models\nwhile following a common implementation and documentation pattern.\n"

Just make sure you have Maven Central enabled in your build file.\n\n[tabs]\n======\nMaven::\n+\n[source,xml,indent=0,subs=\"verbatim,quotes\"]\n----\n<!-- Maven Central is included by default in Maven builds.\n     You usually don’t need to configure it explicitly,\n     but it's shown here for clarity. -->\n<repositories>\n    <repository>\n        <id>central</id>\n        <url>https://repo.maven.apache.org/maven2</url>\n    </repository>\n</repositories>\n----\n\nGradle::\n+\n[source,groovy,indent=0,subs=\"verbatim,quotes\"]\n----\nrepositories {\n    mavenCentral()\n}\n----\n======\n\n\n=== Snapshots - Add Snapshot Repositories\n\nTo use the latest development versions (e.g. `2.0.0-SNAPSHOT`), you need to add the following snapshot repositories in your build file.\n\nAdd the following repository definitions to your Maven or Gradle build file:\n\n[tabs]\n======\nMaven::\n+\n[source,xml,indent=0,subs=\"verbatim,quotes\"]\n----\n  <repositories>\n    <repository>\n      <id>spring-snapshots</id>\n      <name>Spring Snapshots</name>\n      <url>https://repo.spring.io/snapshot</url>\n      <releases>\n        <enabled>false</enabled>\n      </releases>\n    </repository>\n    <repository>\n      <name>Central Portal Snapshots</name>\n      <id>central-portal-snapshots</id>\n      <url>https://central.sonatype.com/repository/maven-snapshots/</url>\n      <releases>\n        <enabled>false</enabled>\n      </releases>\n      <snapshots>\n        <enabled>true</enabled>\n      </snapshots>\n    </repository>\n  </repositories>\n----\n\nGradle::\n+\n[source,groovy,indent=0,subs=\"verbatim,quotes\"]\n----\nrepositories {\n  mavenCentral()\n  maven { url 'https://repo.spring.io/milestone' }\n  maven { url 'https://repo.spring.io/snapshot' }\n  maven {\n    name = 'Central Portal Snapshots'\n    url = 'https://central.sonatype.com/repository/maven-snapshots/'\n  }  \n}\n----\n======\n\n**NOTE:** When using Maven with Spring AI snapshots, pay attention to your Maven mirror configuration. If you have configured a mirror in your `settings.xml` like this:\n\n[source,xml]\n----\n<mirror>\n    <id>my-mirror</id>\n    <mirrorOf>*</mirrorOf>\n    <url>https://my-company-repository.com/maven</url>\n</mirror>\n----\n\nThe wildcard `*` will redirect all repository requests to your mirror, preventing access to Spring snapshot repositories. To fix this, modify the `mirrorOf` configuration to exclude Spring repositories:\n\n[source,xml]\n----\n<mirror>\n    <id>my-mirror</id>\n    <mirrorOf>*,!spring-snapshots,!central-portal-snapshots</mirrorOf>\n    <url>https://my-company-repository.com/maven</url>\n</mirror>\n----\n\nThis configuration allows Maven to access Spring snapshot repositories directly while still using your mirror for other dependencies.\n\n\n[[dependency-management]]\n== Dependency Management\n\nThe Spring AI Bill of Materials (BOM) declares the recommended versions of all the dependencies used by a given release of Spring AI.\nThis is a BOM-only version and it just contains dependency management and no plugin declarations or direct references to Spring or Spring Boot.\nYou can use the Spring Boot parent POM, or use the BOM from Spring Boot (`spring-boot-dependencies`) to manage Spring Boot versions.\n\nAdd the BOM to your project:\n\n[tabs]\n======\nMaven::\n+\n[source,xml,indent=0,subs=\"verbatim,quotes\"]\n----\n<dependencyManagement>\n    <dependencies>\n        <dependency>\n            <groupId>org.springframework.ai</groupId>\n            <artifactId>spring-ai-bom</artifactId>\n            <version>2.0.0</version>\n            <type>pom</type>\n            <scope>import</scope>\n        </dependency>\n    </dependencies>\n</dependencyManagement>\n----\n\nGradle::\n+\n[source,groovy,indent=0,subs=\"verbatim,quotes\"]\n----\ndependencies {\n  implementation platform(\"org.springframework.ai:spring-ai-bom:2.0.0\")\n  // Replace the following with the specific module dependencies (e.g., spring-ai-openai) or starter modules (e.g., spring-ai-starter-model-openai) that you wish to use\n  implementation 'org.springframework.ai:spring-ai-openai'\n}\n----\n+\nGradle users can also use the Spring AI BOM by leveraging Gradle native support for declaring dependency constraints using a Maven BOM.

    "content": "= Dynamic Tool Discovery with Tool Search Tool\n\nAs AI agents connect to more services—Slack, GitHub, Jira, MCP servers—tool libraries grow rapidly. A typical multi-server setup can easily have 50+ tools consuming significant tokens before any conversation starts. Worse, tool selection accuracy degrades when models face 30+ similarly-named tools.\n\nThe **Tool Search Tool** pattern, link:https://www.anthropic.com/engineering/advanced-tool-use[pioneered by Anthropic], addresses this: instead of loading all tool definitions upfront, the model discovers tools on-demand. It receives only a search tool initially, queries for capabilities when needed, and gets relevant tool definitions expanded into context.\n\nSpring AI's implementation achieves **34-64% token reduction** across OpenAI, Anthropic, and Gemini models while maintaining full access to hundreds of tools.\n\n== Introduction\n\nThe link:https://github.com/spring-ai-community/spring-ai-tool-search-tool[Tool Search Tool] project extends Spring AI's xref:api/advisors-recursive.adoc[Recursive Advisors] to implement dynamic tool discovery that works across **any LLM provider** supported by Spring AI.\n\n**Key benefits:**\n\n* **Token savings** - Only discovered tool definitions are sent to the LLM\n* **Improved accuracy** - Models select tools more reliably from smaller, relevant sets\n* **Scalability** - Manage hundreds of tools without context bloat\n* **Portability** - Works with OpenAI, Anthropic, Gemini, Ollama, Azure OpenAI, and more\n\n== Blog Post\n\n📖 **Full Tutorial:** link:https://spring.io/blog/2025/12/11/spring-ai-tool-search-tools-tzolov[Smart Tool Selection: Achieving 34-64% Token Savings with Spring AI's Dynamic Tool Discovery]\n\nThe blog post covers the complete implementation details, performance benchmarks, and advanced use cases.\n\n== Quick Start\n\n=== Dependencies\n\nAdd the Tool Search Tool dependency to your project:\n\n[tabs]\n======\nMaven::\n+\n[source,xml]\n----\n<dependency>\n    <groupId>org.springaicommunity</groupId>\n    <artifactId>tool-search-tool</artifactId>\n    <version>2.0.0</version>\n</dependency>\n\n<!-- Choose a search strategy -->\n<dependency>\n    <groupId>org.springaicommunity</groupId>\n    <artifactId>tool-searcher-lucene</artifactId>\n    <version>2.0.0</version>\n</dependency>\n----\n\nGradle::\n+\n[source,gradle]\n----\ndependencies {\n    implementation 'org.springaicommunity:tool-search-tool:2.0.0'\n    \n    // Choose a search strategy\n    implementation 'org.springaicommunity:tool-searcher-lucene:2.0.0'\n}\n----\n======\n\nNOTE: Version link:https://github.com/spring-ai-community/spring-ai-tool-search-tool/tree/1.0.x[v1.0.x] is Spring AI 1.1.x / Spring Boot 3 compatible.

    "content": "= LLM Response Evaluation with LLM-as-a-Judge\n\nThe challenge of evaluating Large Language Model (LLM) outputs is critical for notoriously non-deterministic AI applications, especially as they move into production.\nTraditional metrics like ROUGE and BLEU fall short when assessing the nuanced, contextual responses that modern LLMs produce.\nHuman evaluation, while accurate, is expensive, slow, and doesn't scale.\n\n**LLM-as-a-Judge** is a powerful technique that uses LLMs themselves to evaluate the quality of AI-generated content.\nResearch link:https://arxiv.org/pdf/2306.05685[shows] that sophisticated judge models can align with human judgment up to 85%, which is actually higher than human-to-human agreement (81%).\n\nSpring AI's xref:api/advisors-recursive.adoc[Recursive Advisors] provide an elegant framework for implementing LLM-as-a-Judge patterns, enabling you to build self-improving AI systems with automated quality control.\n\nTIP: Find the full example implementation in the link:https://github.com/spring-projects/spring-ai-examples/tree/main/advisors/evaluation-recursive-advisor-demo[evaluation-recursive-advisor-demo].\n\n== Understanding LLM-as-a-Judge\n\nLLM-as-a-Judge is an evaluation method where Large Language Models assess the quality of outputs generated by other models or themselves.\nInstead of relying solely on human evaluators or traditional automated metrics, the LLM-as-a-Judge leverages an LLM to score, classify, or compare responses based on predefined criteria.\n\n**Why does it work?** Evaluation is fundamentally easier than generation.\nWhen you use an LLM as a judge, you're asking it to perform a simpler, more focused task (assessing specific properties of existing text) rather than the complex task of creating original content while balancing multiple constraints.\nA good analogy is that it's easier to critique than to create. Detecting problems is simpler than preventing them.\n\n=== Evaluation Patterns\n\nThere are two primary LLM-as-a-judge evaluation patterns:\n\n* **Direct Assessment** (Point-wise Scoring): Judge evaluates individual responses, providing feedback that can refine prompts through self-refinement\n* **Pairwise Comparison**: Judge selects the better of two candidate responses (common in A/B testing)\n\nLLM judges evaluate quality dimensions such as relevance, factual accuracy, faithfulness to sources, instruction adherence, and overall coherence & clarity across domains like healthcare, finance, RAG systems, and dialogue.\n\n== Choosing the Right Judge Model\n\nWhile general-purpose models like GPT-4 and Claude can serve as effective judges, **dedicated LLM-as-a-Judge models consistently outperform them** in evaluation tasks.\nThe link:https://huggingface.co/spaces/AtlaAI/judge-arena[Judge Arena Leaderboard] tracks the performance of various models specifically for judging tasks.\n\n== Implementation with Recursive Advisors\n\nSpring AI's xref:api/chatclient.adoc[ChatClient] provides a fluent API ideal for implementing LLM-as-a-Judge patterns.\nIts xref:api/advisors.adoc[Advisors system] allows you to intercept, modify, and enhance AI interactions in a modular, reusable way.\n\nThe xref:api/advisors-recursive.adoc[Recursive Advisors] take this further by enabling looping patterns that are perfect for self-refining evaluation workflows:\n\n[source,java]\n----\npublic class MyRecursiveAdvisor implements CallAdvisor {\n\n    @Override\n    public ChatClientResponse adviseCall(ChatClientRequest request, CallAdvisorChain chain) {\n\n        // Call the chain initially\n        ChatClientResponse response = chain.nextCall(request);\n\n

AI responses and retries failed attempts with feedback-driven improvement: generate response → evaluate quality → retry with feedback if needed → repeat until quality threshold is met or retry limit reached.\n\n== The SelfRefineEvaluationAdvisor\n\nimage::https://raw.githubusercontent.com/spring-io/spring-io-static/refs/heads/main/blog/tzolov/20251031/spring-ai-evaluation-advisor.png[Self Refine Evaluation Advisor,400]\n\nThis implementation demonstrates the **Direct Assessment** evaluation pattern, where a judge model evaluates individual responses using a point-wise scoring system (1-4 scale).\nIt combines this with a **self-refinement strategy** that automatically retries failed evaluations by incorporating specific feedback into subsequent attempts, creating an iterative improvement loop.\n\nThe advisor embodies two key LLM-as-a-Judge concepts:\n\n* **Point-wise Evaluation**: Each response receives an individual quality score based on predefined criteria\n* **Self-Refinement**: Failed responses trigger retry attempts with constructive feedback to guide improvement\n\n(Based on the article:

enabling multiple evaluation rounds while maintaining proper advisor ordering.\n\n**Structured Evaluation Output**\n\nUsing Spring AI's xref:api/structured-output-converter.adoc[structured output] capabilities, the evaluation results are parsed into an `EvaluationResponse` record with rating (1-4), evaluation rationale, and specific feedback for improvement.\n\n**Separate Evaluation Model**\n\nUses a specialized LLM-as-a-Judge model (e.g., `avcodes/flowaicom-flow-judge:q4`) with a different ChatClient instance to mitigate model biases.\nSet `spring.ai.chat.client.enabled=false` to enable xref:api/chatclient.adoc#_working_with_multiple_chat_models[Working with Multiple Chat Models].\n\n**Feedback-Driven Improvement**\n\nFailed evaluations include specific feedback that gets incorporated into retry attempts, enabling the system to learn from evaluation failures.\n\n**Configurable Retry Logic**\n\nSupports configurable maximum attempts with graceful degradation when evaluation limits are reached.\n\n== Complete Example\n\nHere's how to integrate the `SelfRefineEvaluationAdvisor` into a complete Spring AI application:\n\n[source,java]\n----\n@SpringBootApplication\npublic class EvaluationAdvisorDemoApplication {\n\n    @Bean\n    CommandLineRunner commandLineRunner(AnthropicChatModel anthropicChatModel, OllamaChatModel ollamaChatModel) {\n        return args -> {\n\n            ChatClient chatClient = ChatClient.builder(anthropicChatModel)\n                    .defaultTools(new MyTools())\n                    .defaultAdvisors(\n\n                        SelfRefineEvaluationAdvisor.builder()\n                            .chatClientBuilder(ChatClient.builder(ollamaChatModel)) // Separate model for evaluation\n                            .maxRepeatAttempts(15)\n                            .successRating(4)\n                            .order(0)\n                            .build(),\n\n                        new MyLoggingAdvisor(2))\n                .build();\n\n            var answer = chatClient\n                .prompt(\"What is current weather in Paris?\")\n                .call()\n                .content();\n\n            System.out.println(answer);\n        };\n    }\n\n    static class MyTools {\n        final int[] temperatures = {-125, 15, -255};\n        private final Random random = new Random();\n\n        @Tool(description = \"Get the current weather for a given location\")\n        public String weather(String location) {\n            int temperature = temperatures[random.nextInt(temperatures.length)];\n            System.out.println(\">>> Tool Call responseTemp: \" + temperature);\n            return \"The current weather in \" + location + \" is sunny with a temperature of \" + temperature + \"°C.\";\n        }\n    }\n}\n----\n\nThis configuration:\n\n* Uses Anthropic Claude for generation and Ollama for evaluation (avoiding bias)\n* Requires rating of 4 with up to 15 retry attempts\n* Includes weather tool that generates randomized responses to trigger evaluations\n* The `weather` tool generates invalid values in 2/3 of the cases\n\nThe `SelfRefineEvaluationAdvisor` (Order 0) evaluates response quality and retries with feedback if needed, followed by `MyLoggingAdvisor` (Order 2) which logs the final request/response for observability.\n\nWhen run, you would see output like this:\n\n[source,text]\n----\nREQUEST: [{\"role\":\"user\",\"content\":\"What is current weather in Paris?\"}]\n\n>>> Tool Call responseTemp: -255\nEvaluation failed on attempt 1, evaluation: The response contains unrealistic temperature data, feedback: The temperature of -255°C is physically impossible and indicates a data error.\n\n>>> Tool Call responseTemp: 15\nEvaluation passed on attempt 2, evaluation: Excellent response with realistic weather data\n\nRESPONSE: The current weather in Paris is sunny with a temperature of 15°C.\n----\n\nTIP: The complete runnable demo with configuration examples, including different model combinations and evaluation scenarios, is available in the

success factors when implementing the LLM-as-a-Judge technique include:\n\n* **Use dedicated judge models** for better performance (see link:https://huggingface.co/spaces/AtlaAI/judge-arena[Judge Arena Leaderboard])\n* **Mitigate bias** through separate generation/evaluation models\n* **Ensure deterministic results** (temperature = 0)\n* **Engineer prompts** with integer scales and few-shot examples\n* **Maintain human oversight** for high-stakes decisions\n\n[WARNING]\n====\n**Recursive Advisors are a new experimental feature in Spring AI 1.1.0-M4+.**\nCurrently, they are non-streaming only, require careful advisor ordering, and can increase costs due to multiple LLM calls.\n\nBe especially careful with inner advisors that maintain external state - they may require extra attention to maintain correctness across iterations.\n\nAlways set termination conditions and retry limits to prevent infinite loops.\n====\n\n== Related Documentation\n\n*

    "content": "[[upgrade-notes]]\n= Upgrade Notes\n\n[[upgrading-to-2-0-0-M5]]\n== Upgrading to 2.0.0-M5\n\n=== OpenAI Java SDK Transition\n\nStarting from version `2.0.0-M5`, Spring AI uses the official `openai-java` SDK under the hood for all OpenAI models (Chat, Embeddings, Image, Audio Speech, Audio Transcription, and Moderation).\n\nThe transition is seamless, and **no breaking changes are expected** for existing users of the `spring-ai-openai` module.\nAll properties (with the `spring.ai.openai.*` prefix), builders, and options remain fully intact. The existing `extraBody` configuration parameter transparently maps to the underlying `additionalBodyProperties` in the `openai-java` SDK.\n\n=== ChatOptions Handling\nUsers can interact with ChatModels in two ways:\n\n * either directly by calling xref:api/chatmodel.adoc[ ChatModel.call(Prompt) / ChatModel.stream(Prompt)`],\n * or by using the xref:api/chatclient.adoc[ChatClient] API.\n\nStarting with Spring AI 2.0.0.M5, when using the `ChatModel` approach, options set in the prompt need to be of the concrete type used by the concrete model (_e.g._ `AnthropicChatOptions` when using `AnthropicChatModel`) and need to be either \"full\" (_i.e._ all relevant fields set) or `null` (in which case the default options set in the model will be used).\n\nThe ability to \"merge\" options has been moved to `ChatClient` (using a `ChatOptions.Builder` or more specific type) and happens prior to the first advisor being called.\n\nCode that previously used a \"half constructed\" instance of `ChatOptions` now needs to an instance of `Builder` built in a similar way:\n[source,java]\n----\n// Old\nChatClient client = ...;\nChatOptions opts = AnthropicChatOptions.builder()\n    .maxTokens(100)\n    .temperature(0.7)\n    .disableParallelToolUse(true)\n    .build();\nString response = client.prompt(\"Tell me a joke\")\n    .options(opts)\n    .call().content();\n\n// New\nChatClient client = ...;\nvar customizer =  AnthropicChatOptions.builder()\n    .maxTokens(100)\n    .temperature(0.7)\n    .disableParallelToolUse(true);\nString response = client.prompt(\"Tell me a joke\")\n    .options(customizer)\n    .call().content();\n----\n\n\n[TIP]\n--\nTo easily merge a \"delta\" of options represented by a `ChatOptions.Builder` with the model's default options at the `ChatModel.call()` level, simply use the following construct:\n[source, java]\n----\nChatModel model = ...;\nvar customizer =  AnthropicChatOptions.builder()\n    .maxTokens(100)\n    .temperature(0.7)\n    .disableParallelToolUse(true);\nPrompt prompt = Prompt.builder().message(\"Tell me a joke\")\n    .options(model.getDefaultOptions().mutate().combineWith(customize).build())\n    .build();\nvar response = model.call(prompt);\n----\n--\n\n\n[[upgrading-to-2-0-0-M3]]\n== Upgrading to 2.0.0-M3\n\n=== MCP Annotations Migrated into Spring AI\n\nThe `org.springaicommunity:mcp-annotations` external library has been removed as a dependency of the `mcp-annotations` module.\nIts classes are now part of Spring AI itself under a new package structure.\n\n==== Impact\n\n* All MCP annotation and provider classes have new fully-qualified names.\n* The `org.springaicommunity:mcp-annotations` artifact is no longer provided transitively by Spring AI.\n* Any code importing from `org.springaicommunity.mcp.*` will fail to compile.\n\n==== Package Rename\n\n[cols=\"1,1\", options=\"header\"]\n|===\n| Old Package | New Package\n| `org.springaicommunity.mcp.annotation.*` | `org.springframework.ai.mcp.annotation.*`\n| `org.springaicommunity.mcp.method.*` | `org.springframework.ai.mcp.annotation.method.*`\n| `org.springaicommunity.mcp.provider.*` | `org.springframework.ai.mcp.annotation.provider.*`\n|===\n\n==== Migration\n\nUpdate all imports in your application code:\n\n[source,java]\n----\n// Before\nimport org.springaicommunity.mcp.annotation.McpTool;\nimport org.springaicommunity.mcp.annotation.McpPrompt;\nimport org.springaicommunity.mcp.annotation.McpResource;\nimport org.springaicommunity.mcp.annotation.McpSampling;\nimport org.springaicommunity.mcp.provider.tool.SyncMcpToolProvider;\nimport org.springaicommunity.mcp.provider.prompt.AsyncMcpPromptProvider;\n\n// After\nimport org.springframework.ai.mcp.annotation.McpTool;\nimport org.springframework.ai.mcp.annotation.McpPrompt;\nimport org.springframework.ai.mcp.annotation.McpResource;\nimport org.springframework.ai.mcp.annotation.McpSampling;\nimport org.springframework.ai.mcp.annotation.provider.tool.SyncMcpToolProvider;\nimport org.springframework.ai.mcp.annotation.provider.prompt.AsyncMcpPromptProvider;\n----\n\nIf you declared `org.springaicommunity:mcp-annotations` as a direct Maven or Gradle dependency, remove it — the classes are now provided by Spring AI's `spring-ai-mcp-annotations` module.\n\n==== Automated Migration with OpenRewrite\n\nYou can automate all import and dependency changes using the provided OpenRewrite recipe.\n\nApply the https://github.com/spring-projects/spring-ai/blob/main/src/rewrite/migrate-to-2-0-0-M3.yaml[`migrate-to-2-0-0-M3.yaml`] recipe from the command line:\n\n[source,shell]\n----\nmvn org.openrewrite.maven:rewrite-maven-plugin:6.32.0:run \\\n  -Drewrite.configLocation=https://raw.githubusercontent.com/spring-projects/spring-ai/refs/heads/main/src/rewrite/migrate-to-2-0-0-M3.yaml \\\n  -Drewrite.activeRecipes=org.springframework.ai.migration.M3MigrateMcpAnnotations \\\n  -Dmaven.compiler.failOnError=false\n----\n\nThe recipe performs two changes automatically:\n\n1. **Removes** the `org.springaicommunity:mcp-annotations` Maven dependency.\n2. **Rewrites** all `import` statements across `.java` files to point to the new `org.springframework.ai.mcp.annotation.*` packages.\n\nTo

transport modules are no longer shipped by the MCP Java SDK. Starting with Spring AI 2.0, they are part of the Spring AI project itself.\n\n==== Impact\n\n* The Maven group ID for both artifacts has changed.\n* Java package names for all Spring-specific transport classes have changed.\n* The MCP Java SDK version requirement has been bumped from `0.18.x` to `1.0.x`.\n\n==== Maven Dependency Group ID Change\n\n.Before\n[source,xml]\n----\n<dependency>\n    <groupId>io.modelcontextprotocol.sdk</groupId>\n    <artifactId>mcp-spring-webflux</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>io.modelcontextprotocol.sdk</groupId>\n    <artifactId>mcp-spring-webmvc</artifactId>\n</dependency>\n----\n\n.After\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>mcp-spring-webflux</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>mcp-spring-webmvc</artifactId>\n</dependency>\n----\n\nNOTE: When using the `spring-ai-bom` or a Spring AI MCP starter (`spring-ai-starter-mcp-server-webflux`, `spring-ai-starter-mcp-server-webmvc`, `spring-ai-starter-mcp-client-webflux`), **no explicit version is needed** — the BOM manages it automatically.\n\n==== Java Package Relocation\n\nAll Spring-specific transport classes have moved to `org.springframework.ai` packages.\n\n.Server transports\n|===\n|Class |Old package |New package\n\n|`WebFluxSseServerTransportProvider`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webflux.transport`\n\n|`WebFluxStreamableServerTransportProvider`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webflux.transport`\n\n|`WebFluxStatelessServerTransport`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webflux.transport`\n\n|`WebMvcSseServerTransportProvider`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webmvc.transport`\n\n|`WebMvcStreamableServerTransportProvider`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webmvc.transport`\n\n|`WebMvcStatelessServerTransport`\n|`io.modelcontextprotocol.server.transport`\n|`org.springframework.ai.mcp.server.webmvc.transport`\n|===\n\n.Client transports\n|===\n|Class |Old package |New package\n\n|`WebFluxSseClientTransport`\n|`io.modelcontextprotocol.client.transport`\n|`org.springframework.ai.mcp.client.webflux.transport`\n\n|`WebClientStreamableHttpTransport`\n|`io.modelcontextprotocol.client.transport`\n|`org.springframework.ai.mcp.client.webflux.transport`\n|===\n\n==== Migration\n\nUpdate your Java imports:\n\n[source,java]\n----\n// Before\nimport io.modelcontextprotocol.server.transport.WebFluxSseServerTransportProvider;\nimport io.modelcontextprotocol.server.transport.WebMvcSseServerTransportProvider;\nimport io.modelcontextprotocol.client.transport.WebFluxSseClientTransport;\nimport io.modelcontextprotocol.client.transport.WebClientStreamableHttpTransport;\n\n// After\nimport org.springframework.ai.mcp.server.webflux.transport.WebFluxSseServerTransportProvider;\nimport org.springframework.ai.mcp.server.webmvc.transport.WebMvcSseServerTransportProvider;\nimport org.springframework.ai.mcp.client.webflux.transport.WebFluxSseClientTransport;\nimport org.springframework.ai.mcp.client.webflux.transport.WebClientStreamableHttpTransport;\n----\n\nNOTE: If you rely exclusively on Spring Boot auto-configuration via the Spring AI starters, **no Java code changes are required**. Only update your `pom.xml`/`build.gradle` dependency coordinates as described above.\n\n\nFor the full MCP transport migration reference, see xref:api/mcp/mcp-overview.adoc#_upgrading_to_spring_ai_2_0[Upgrading to Spring AI 2.0].\n\n\n==== Automated Migration with OpenRewrite\n\nYou can automate all Maven dependency and Java import changes using the provided OpenRewrite recipe:\n\n[source,shell]\n----\nmvn org.openrewrite.maven:rewrite-maven-plugin:6.32.0:run \\\n  -Drewrite.configLocation=https://raw.githubusercontent.com/spring-projects/spring-ai/refs/heads/main/src/rewrite/migrate-to-2-0-0-M3.yaml \\\n  -Drewrite.activeRecipes=org.springframework.ai.migration.M3MigrateMcpSpringTransports \\\n  -Dmaven.compiler.failOnError=false\n----\n\nIMPORTANT: If your project declares `io.modelcontextprotocol.sdk:mcp-spring-webflux` or `mcp-spring-webmvc` *without* an explicit `<version>` (version managed via a BOM), Maven will refuse to parse the `pom.xml` and the recipe will never run.\nPre-patch those files first, then run OpenRewrite:\n\n[source,shell]\n----\n# Step 1 – patch the groupIds directly so Maven can load the modules\nfind . -name \"pom.xml\" -print0 \\\n  | xargs -0 perl -i -0pe \\\n    's{<groupId>io\\.modelcontextprotocol\\.sdk</groupId>(\\s+)<artifactId>mcp-spring-webflux</artifactId>}{<groupId>org.springframework.ai</groupId>$1<artifactId>mcp-spring-webflux</artifactId>}g;\n     s{<groupId>io\\.modelcontextprotocol\\.sdk</groupId>(\\s+)<artifactId>mcp-spring-webmvc</artifactId>}{<groupId>org.springframework.ai</groupId>$1<artifactId>mcp-spring-webmvc</artifactId>}g'\n\n# Step 2 – run OpenRewrite to migrate Java imports and remaining POM changes\nmvn org.openrewrite.maven:rewrite-maven-plugin:6.32.0:run \\\n  -Drewrite.configLocation=https://raw.githubusercontent.com/spring-projects/spring-ai/refs/heads/main/src/rewrite/migrate-to-2-0-0-M3.yaml \\\n  -Drewrite.activeRecipes=org.springframework.ai.migration.M3MigrateMcpSpringTransports \\\n  -Dmaven.compiler.failOnError=false\n----\n\nTo run all M3 migrations at once, use the umbrella recipe — see <<run-all-m3-migrations>>.\n\n=== MCP Client Customizer API Consolidated\n\n`McpAsyncClientCustomizer` and `McpSyncClientCustomizer` have been removed and replaced by a single generic interface `McpClientCustomizer<B>`.\n\n==== Impact\n\n* `McpAsyncClientCustomizer` no longer exists — compile error for any implementing bean.\n* `McpSyncClientCustomizer` no longer exists — compile error for any implementing bean.\n* `McpSyncClientConfigurer` and `McpAsyncClientConfigurer` constructors now accept `List<McpClientCustomizer<...>>` instead of the old type-specific lists.\n* In the HttpClient-based transport auto-configurations (`SseHttpClientTransportAutoConfiguration`, `StreamableHttpHttpClientTransportAutoConfiguration`), the SDK-level `McpSyncHttpClientRequestCustomizer` and `McpAsyncHttpClientRequestCustomizer` beans are **no longer applied**. Transport-level customization now goes through `McpClientCustomizer<HttpClientSseClientTransport.Builder>` and `McpClientCustomizer<HttpClientStreamableHttpTransport.Builder>` respectively.\n\n==== Migration\n\nReplace your customizer beans with the new generic interface, parameterized by the spec or builder type you need:\n\n[source,java]\n----\n// Before\n@Bean\npublic McpSyncClientCustomizer mySyncCustomizer() {\n    return (name, spec) -> spec.requestTimeout(Duration.ofSeconds(30));\n}\n\n@Bean\npublic McpAsyncClientCustomizer myAsyncCustomizer() {\n    return (name, spec) -> spec.requestTimeout(Duration.ofSeconds(30));\n}\n\n// After\n@Bean\npublic McpClientCustomizer<McpClient.SyncSpec> mySyncCustomizer() {\n    return (name, spec) -> spec.requestTimeout(Duration.ofSeconds(30));\n}\n\n@Bean\npublic McpClientCustomizer<McpClient.AsyncSpec> myAsyncCustomizer() {\n    return (name, spec) -> spec.requestTimeout(Duration.ofSeconds(30));\n}\n----\n\nFor HttpClient transport customization (previously done via `McpSyncHttpClientRequestCustomizer` / `McpAsyncHttpClientRequestCustomizer`):\n\n[source,java]\n----\n// Before\n@Bean\npublic McpSyncHttpClientRequestCustomizer myRequestCustomizer() {\n    return requestBuilder -> requestBuilder.header(\"Authorization\", \"Bearer token\");\n}\n\n// After\n@Bean\npublic McpClientCustomizer<HttpClientSseClientTransport.Builder> mySseTransportCustomizer() {\n    return (name, builder) -> builder.httpRequestCustomizer(\n        req -> req.header(\"Authorization\", \"Bearer token\")\n    );\n}\n----\n\n==== Automated Migration with OpenRewrite\n\nYou can automate the import and type changes using the provided OpenRewrite recipe:\n\n[source,shell]\n----\nmvn org.openrewrite.maven:rewrite-maven-plugin:6.32.0:run \\\n  -Drewrite.configLocation=https://raw.githubusercontent.com/spring-projects/spring-ai/refs/heads/main/src/rewrite/migrate-to-2-0-0-M3.yaml \\\n  -Drewrite.activeRecipes=org.springframework.ai.migration.M3MigrateMcpClientCustomizer \\\n  -Dmaven.compiler.failOnError=false\n----\n\nThe recipe performs the following changes automatically:\n\n1. **Replaces** the `McpAsyncClientCustomizer` and `McpSyncClientCustomizer` imports with `McpClientCustomizer` and adds the required `import io.modelcontextprotocol.client.McpClient;`.\n2. **Rewrites** `implements McpAsyncClientCustomizer` to `implements McpClientCustomizer<McpClient.AsyncSpec>`.\n3. **Rewrites** `implements McpSyncClientCustomizer` to `implements McpClientCustomizer<McpClient.SyncSpec>`.\n4. **Rewrites** all remaining usages (return types, variable declarations, parameter types).\n\nNOTE: `McpSyncHttpClientRequestCustomizer` and `McpAsyncHttpClientRequestCustomizer` beans are no longer applied by the transport auto-configurations. Their migration to `McpClientCustomizer<TransportBuilder>` requires a manual step — the target builder type depends on which transport you are configuring (SSE vs. Streamable HTTP).\n\nTo run all M3 migrations at once, use the umbrella recipe — see <<run-all-m3-migrations>>.\n\n=== MCP WebMvc Transport Headers Normalized to Lowercase\n\nIn `WebMvcSseServerTransportProvider`, `WebMvcStatelessServerTransport`, and `WebMvcStreamableServerTransportProvider`, the `Map<String, List<String>>` passed to `securityValidator.validateHeaders(headers)` now has all header names normalized to **lowercase**.\n\nPreviously, header names were passed with their original HTTP case (e.g. `\"Authorization\"`, `\"Content-Type\"`). They are now always lowercase (e.g. `\"authorization\"`, `\"content-type\"`).\n\n==== Impact\n\nCustom `ServerTransportSecurityValidator` implementations that look up headers by their mixed-case names will silently fail to find them.\n\n==== Migration\n\nUpdate all header name lookups in your `ServerTransportSecurityValidator` to use lowercase keys:\n\n[source,java]\n----\n// Before\npublic void validateHeaders(Map<String, List<String>> headers) {\n    List<String> authHeader = headers.get(\"Authorization\");\n    // ...\n}\n\n// After\npublic void validateHeaders(Map<String, List<String>> headers) {\n    List<String> authHeader = headers.get(\"authorization\");\n    // ...\n}\n----\n\n=== Conversation History Removed from ToolContext\n\nConversation history is no longer automatically added to `ToolContext`. The `TOOL_CALL_HISTORY` constant and `getToolCallHistory()` method have been removed from the `ToolContext` class.\n\n==== Impact\n\n* `ToolContext.TOOL_CALL_HISTORY` constant no longer exists\n* `ToolContext.getToolCallHistory()` method no longer exists\n* Conversation history is no longer automatically populated in `ToolContext`\n\n==== Why This Change?\n\n1. **Memory Efficiency**: Prevents unbounded memory growth in long conversations\n2. **Separation of Concerns**: Tools should operate on their parameters, not manage conversation state\n3. **Architecture Alignment**: Conversation context belongs at the advisor level, not in tool execution\n\n==== Migration\n\nIf your application needs conversation history management, use `ToolCallAdvisor`:\n\n.Managing Conversation History with ToolCallAdvisor\n[source,java]\n----\nChatClient chatClient = ChatClient.builder()\n    .defaultAdvisors(\n        new ToolCallAdvisor()\n            .conversationHistoryEnabled(true)  // Full history (default)\n    )\n    .build();\n----\n\n**How ToolCallAdvisor Works:**\n\nThe `ToolCallAdvisor` manages conversation history at the advisor level:\n\n* **conversationHistoryEnabled=true** (default): Full conversation history is maintained and sent to the LLM between tool call iterations, allowing the LLM to synthesize results with full context\n* **conversationHistoryEnabled=false**: Only the most recent tool response is sent to the LLM (useful when ChatMemory advisor manages history separately)\n\n**Key Point:** The conversation history is used by the *LLM* to understand context and formulate responses, not by the *tools* themselves. Tools receive only their input parameters and any custom context you explicitly provide.\n\n**Custom Context in Tools:**\n\n`ToolContext` remains available for passing custom, application-specific data to tools:\n\n.Passing Custom Context to Tools\n[source,java]\n----\nChatResponse response = chatClient.prompt()\n    .user(\"What's the weather in SF?\")\n    .options(ChatOptionsBuilder.builder()\n        .toolContext(\"userId\", \"user123\")\n        .toolContext(\"apiKey\", \"secret\")\n        .build())\n    .call()\n    .chatResponse();\n----\n\n**Example Flow:**\n\n1. User asks: \"What's the weather in SF and LA?\"\n2. LLM requests tool calls: `getWeather(SF)` and `getWeather(LA)`\n3. Tools execute with only their parameters (no conversation history)\n4. ToolCallAdvisor collects tool results and conversation history\n5. LLM receives conversation context from advisor and synthesizes: \"The weather in SF is 72°F and in LA is 85°F\"\n\nThe LLM sees the full conversation through the advisor chain, not through ToolContext.\n\n==== The access level of model internal methods changed to private\n\n* All `internalCall` and `internalStream` methods in model classes have been changed to `private`.\n\n===== Impact\n\n* Direct calls `xxxModel.internalCall` or `xxxModel.internalStream` method, will fail to compile.\n\n===== Migration\n\n* Replace all calls to `xxxModel.internalCall` with `xxxModel.call`.\n* Replace all calls to `xxxModel.internalStream` with `xxxModel.stream`.\n+\n[source,java]\n----\n// Before\nChatResponse response = model.internalCall(prompt, previousChatResponse);\nFlux<ChatResponse> responseFlux = model.internalStream(prompt, previousChatResponse);\n\n// After\nChatResponse response = model.call(prompt);\nFlux<ChatResponse> responseFlux = model.stream(prompt);\n----\n\n=== OpenSearch Dependencies Upgraded\n\nThe OpenSearch vector store dependencies have been upgraded to newer versions:\n\n* **OpenSearch Java Client**: `2.23.0` → `3.6.0`\n* **OpenSearch Testcontainers**: `2.0.1` → `4.1.0`\n\n==== Background\n\nThis upgrade was necessary for compatibility with Spring Boot 4.1.x, which uses HttpClient5 (`org.apache.httpcomponents.client5:httpclient5`) version 5.6. This version of HttpClient has a gzip content formatter breaking change that required the OpenSearch Java Client upgrade. See https://github.com/opensearch-project/opensearch-java/pull/1851[OpenSearch Java PR #1851] for details.\n\n==== Impact\n\nThe OpenSearch Java Client 3.x introduces breaking API changes that affect custom code interacting directly with the native OpenSearch client.\n\n==== Migration\n\nIf you're using the OpenSearch vector store through Spring AI's `VectorStore` interface, no action is required. The upgrade is transparent.\n\n**Testcontainers class renamed**: `OpensearchContainer` → `OpenSearchContainer` (proper camelCase)\n\nSpring AI's internal implementation has been updated to handle these changes automatically.\n\n=== AbstractFilterExpressionConverter: doSingleValue is now abstract\n\nIn `AbstractFilterExpressionConverter` (used by vector store filter expression converters), the method `doSingleValue(Object value, StringBuilder context)` has been changed from a concrete method to an abstract method. Custom vector store implementations that extend `AbstractFilterExpressionConverter` must now implement this method explicitly.\n\n==== Impact\n\n* Any custom `FilterExpressionConverter` that extends `AbstractFilterExpressionConverter` and did not override `doSingleValue()` will fail to compile.\n* Implementations must convert a single filter value (String, Number, Boolean, Date, etc.) into the target format and append it to the provided `StringBuilder` context.\n\n==== Migration\n\nImplement `doSingleValue(Object value, StringBuilder context)` in your custom converter. You can use the provided static helper methods:\n\n* **JSON-based filters** (e.g. PostgreSQL JSONPath, Neo4j Cypher, Weaviate): use `emitJsonValue(Object value, StringBuilder context)` to serialize values with proper quoting and escaping.\n* **Lucene-based filters** (e.g. Elasticsearch, OpenSearch, GemFire): use `emitLuceneString(String value, StringBuilder context)` for string values, and handle other types (numbers, booleans, dates) according to your store's query syntax.\n* **Other formats**: implement your own logic and append the result to `context`.\n\nNOTE: The framework normalizes values (e.g. ISO date strings converted to `Date`) before invoking `doSingleValue`, so your implementation receives already-normalized values. The static helper `normalizeDateString(Object)` is available if you need the same normalization when building expressions outside of the standard flow.\n\n\n[[run-all-m3-migrations]]\n=== Running All M3 Migrations at Once\n\nThe umbrella recipe `MigrateToSpringAI200M3` applies all three automated M3 migrations in a single pass:\n\n[cols=\"1,2\", options=\"header\"]\n|===\n| Recipe | What it does\n| `M3MigrateMcpAnnotations` | Removes `org.springaicommunity:mcp-annotations` dependency and rewrites imports to `org.springframework.ai.mcp.annotation.*`\n| `M3MigrateMcpSpringTransports` | Updates Maven `<groupId>` and Java imports for the moved Spring transport modules\n| `M3MigrateMcpClientCustomizer` | Replaces `McpAsyncClientCustomizer` / `McpSyncClientCustomizer` with `McpClientCustomizer<B>`\n|===\n\nIf any of your `pom.xml` files declare `io.modelcontextprotocol.sdk:mcp-spring-webflux` or `mcp-spring-webmvc` without an explicit `<version>`, run the Perl pre-patch first (see <<_automated_migration_with_openrewrite_2>>), then execute the umbrella recipe:\n\n[source,shell]\n----\nmvn org.openrewrite.maven:rewrite-maven-plugin:6.32.0:run \\\n  -Drewrite.configLocation=https://raw.githubusercontent.com/spring-projects/spring-ai/refs/heads/main/src/rewrite/migrate-to-2-0-0-M3.yaml \\\n  -Drewrite.activeRecipes=org.springframework.ai.migration.MigrateToSpringAI200M3 \\\n  -Dmaven.compiler.failOnError=false\n----\n\n[[upgrading-to-2-0-0-M2]]\n== Upgrading to 2.0.0-M2\n\n=== Breaking Changes\n\n==== MongoDB Chat Memory Message Ordering Fixed\n\nThe `MongoChatMemoryRepository` has been fixed to return messages in the order they were sent (oldest-to-newest), matching all other chat memory repository implementations. Previously, it incorrectly returned messages in reverse order (newest-to-oldest), which broke conversation flow for LLMs.\n\n===== Impact\n\nIf your application was using `MongoChatMemoryRepository` and working around the incorrect ordering (e.g., by reversing messages after retrieval), you will need to remove that workaround.\n\n===== Migration\n\nRemove any code that reverses the message order after retrieving from MongoDB chat memory:\n\n[source,java]\n----\n// BEFORE (with workaround for bug):\nList<Message> messages = chatMemoryRepository.findByConversationId(conversationId);\nCollections.reverse(messages); // Remove this workaround\n\n// AFTER (correct ordering):\nList<Message> messages = chatMemoryRepository.findByConversationId(conversationId);\n// Messages are now correctly ordered chronologically\n----\n\nAll chat memory repositories now consistently return messages in the order they were sent (oldest-to-newest), which is the expected format for LLM conversation history.\n\n=== Development-time Services\n\n* Docker Compose and Testcontainers support for MongoDB Atlas is now provided natively by the Spring Boot MongoDB module. The migration should be transparent and not require any code change. Regarding dependencies, you don't need to import `org.springframework.ai:spring-ai-spring-boot-testcontainers` anymore. A dependency on `org.springframework.boot:spring-boot-testcontainers` is sufficient.\n\n[[upgrading-to-2-0-0-M1]]\n== Upgrading to 2.0.0-M1\n\n=== Breaking Changes\n\n==== Default Temperature Configuration Removed\n\nSpring AI no longer provides default temperature values for chat model autoconfiguration properties. Previously, Spring AI set a default temperature of `0.7` for most chat models. This default has been removed to allow each AI provider's native default temperature to be used.\n\n===== Impact\n\nIf your application did not explicitly configure a temperature value and relied on Spring AI's default of `0.7`, you may notice different behavior after upgrading. The actual default will now be determined by each AI provider's API, which may vary:\n\n* Some providers default to `1.0`\n* Some providers default to `0.7`\n* Some providers have model-specific defaults\n\n===== Migration\n\nIf you want to maintain the previous behavior, explicitly set the temperature in your configuration:\n\n[source,properties]\n----\n# Example for OpenAI\nspring.ai.openai.chat.options.temperature=0.7\n\n# Example for Anthropic\nspring.ai.anthropic.chat.options.temperature=0.7\n\n# Example for Azure OpenAI\nspring.ai.azure.openai.chat.options.temperature=0.7\n----\n\nOr programmatically when building requests:\n\n[source,java]\n----\nChatResponse response = chatModel.call(\n    new Prompt(\"Your prompt here\",\n        OpenAiChatOptions.builder()\n            .temperature(0.7)\n            .build()));\n----\n\n[[upgrading-to-1-1-0-RC1]]\n== Upgrading to 1.1.0-RC1\n\n=== Breaking Changes\n\n==== Text-to-Speech (TTS) API Migration\n\nThe OpenAI Text-to-Speech implementation has been migrated from provider-specific classes to shared interfaces. This enables writing portable code that works across multiple TTS providers (OpenAI, ElevenLabs, and future providers).\n\n===== Removed Classes\n\nThe following deprecated classes have been removed from the `org.springframework.ai.openai.audio.speech` package:\n\n* `SpeechModel` → Use `TextToSpeechModel` (from `org.springframework.ai.audio.tts`)\n* `StreamingSpeechModel` → Use `StreamingTextToSpeechModel` (from `org.springframework.ai.audio.tts`)\n* `SpeechPrompt` → Use `TextToSpeechPrompt` (from `org.springframework.ai.audio.tts`)\n* `SpeechResponse` → Use `TextToSpeechResponse` (from `org.springframework.ai.audio.tts`)\n* `SpeechMessage` → Use `TextToSpeechMessage` (from `org.springframework.ai.audio.tts`)\n* `Speech` (in `org.springframework.ai.openai.audio.speech`) → Use `Speech` (from `org.springframework.ai.audio.tts`)\n\nAdditionally, the `speed` parameter type changed from `Float` to `Double` across all OpenAI TTS components for consistency with other TTS providers.\n\n===== Migration Steps\n\n1. **Update Imports**: Replace all imports from `org.springframework.ai.openai.audio.speech.*` with `org.springframework.ai.audio.tts.*`\n\n2. **Update Type References**: Replace all occurrences of the old class names with the new ones:\n+\n[source,text]\n----\nFind:    SpeechModel\nReplace: TextToSpeechModel\n\nFind:    StreamingSpeechModel\nReplace: StreamingTextToSpeechModel\n\nFind:    SpeechPrompt\nReplace: TextToSpeechPrompt\n\nFind:    SpeechResponse\nReplace: TextToSpeechResponse\n\nFind:    SpeechMessage\nReplace: TextToSpeechMessage\n----\n\n3. **Update Speed Parameter**: Change from `Float` to `Double`:\n+\n[source,text]\n----\nFind:    .speed(1.0f)\nReplace: .speed(1.0)\n\nFind:    Float speed\nReplace: Double speed\n----\n\n4. **Update Dependency Injection**: If you inject `SpeechModel`, update to `TextToSpeechModel`:\n+\n[source,java]\n----\n// Before\npublic MyService(SpeechModel speechModel) { ... }\n\n// After\npublic MyService(TextToSpeechModel textToSpeechModel) { ... }\n----\n\n===== Benefits\n\n* **Portability**: Write code once, switch between OpenAI, ElevenLabs, or other TTS providers easily\n* **Consistency**: Same patterns as ChatModel and other Spring AI abstractions\n* **Type Safety**: Improved type hierarchy with proper interface implementations\n* **Future-Proof**: New TTS providers will automatically work with your existing code\n\n===== Additional Resources\n\nFor a comprehensive migration guide with detailed code examples, see:\n\n* xref:api/audio/speech/openai-speech.adoc#_migration_guide[OpenAI TTS Migration Guide]\n* xref:api/audio/speech.adoc#_writing_provider_agnostic_code[Writing Provider-Agnostic TTS Code]\n\n\n[[upgrading-to-1-0-0-snapshot]]\n== Upgrading to 1.0.0-SNAPSHOT\n\n=== Overview\nThe 1.0.0-SNAPSHOT version includes significant changes to artifact IDs, package names, and module structure. This section provides guidance specific to using the SNAPSHOT version.\n\n=== Add Snapshot Repositories\n\nTo use the 1.0.0-SNAPSHOT version, you need to add the snapshot repositories to your build file.\nFor detailed instructions, refer to the xref:getting-started.adoc#snapshots-add-snapshot-repositories[Snapshots - Add Snapshot Repositories] section in the Getting Started guide.\n\n=== Update Dependency Management\n\nUpdate your Spring AI BOM version to `1.0.0-SNAPSHOT` in your build configuration.\nFor detailed instructions on configuring dependency management, refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section in the Getting Started guide.\n\n=== Artifact ID, Package, and Module Changes\nThe 1.0.0-SNAPSHOT includes changes to artifact IDs, package names, and module structure.\n\nFor details, refer to:\n- xref:upgrade-notes.adoc#common-artifact-id-changes[Common Artifact ID Changes]\n- xref:upgrade-notes.adoc#common-package-changes[Common Package Changes]\n- xref:upgrade-notes.adoc#common-module-structure[Common Module Structure]\n\n\n[[upgrading-to-1-0-0-RC1]]\n== Upgrading to 1.0.0-RC1\n\nYou can automate the upgrade process to 1.0.0-RC1 using an OpenRewrite recipe.\nThis recipe helps apply many of the necessary code changes for this version.\nFind the recipe and usage instructions at https://github.com/arconia-io/arconia-migrations/blob/main/docs/spring-ai.md[Arconia Spring AI Migrations].\n\n=== Breaking Changes\n\n\n==== Chat Client and Advisors\n\nThe main changes that impact end user code are:\n\n* In `VectorStoreChatMemoryAdvisor`:\n** The constant `CHAT_MEMORY_RETRIEVE_SIZE_KEY` has been renamed to `TOP_K`.\n** The constant `DEFAULT_CHAT_MEMORY_RESPONSE_SIZE` (value: 100) has been renamed to `DEFAULT_TOP_K` with a new default value of 20.\n\n* The constant `CHAT_MEMORY_CONVERSATION_ID_KEY` has been renamed to `CONVERSATION_ID` and moved from `AbstractChatMemoryAdvisor` to the `ChatMemory` interface. Update your imports to use `org.springframework.ai.chat.memory.ChatMemory.CONVERSATION_ID`.\n\n===== Self-contained Templates in Advisors\n\nThe built-in advisors that perform prompt augmentation have been updated to use self-contained templates. The goal is for each advisor to be able to perform templating operations without affecting nor being affected by templating and prompt decisions in other advisors.\n\n*If you were providing custom templates for the following advisors, you'll need to update them to ensure all expected placeholders are included.*\n\n* The `QuestionAnswerAdvisor` expects a template with the following placeholders (see xref:api/retrieval-augmented-generation.adoc#_questionansweradvisor[more details]):\n** a `query` placeholder to receive the user question.\n** a `question_answer_context` placeholder to receive the retrieved context.\n* The `PromptChatMemoryAdvisor` expects a template with the following placeholders (see xref:api/chat-memory.adoc#_promptchatmemoryadvisor[more details]):\n** an `instructions` placeholder to receive the original system message.\n** a `memory` placeholder to receive the retrieved conversation memory.\n* The `VectorStoreChatMemoryAdvisor` expects a template with the following placeholders (see xref:api/chat-memory.adoc#_vectorstorechatmemoryadvisor[more details]):\n** an `instructions` placeholder to receive the original system message.\n** a `long_term_memory` placeholder to receive the retrieved conversation memory.\n\n==== Observability\n* Refactored content observation to use logging instead of tracing (https://github.com/spring-projects/spring-ai/commit/ca843e85887aa1da6300c77550c379c103500897[ca843e8])\n  ** Replaced content observation filters with logging handlers\n  ** Renamed configuration properties to better reflect their purpose:\n    *** `include-prompt` → `log-prompt`\n    *** `include-completion` → `log-completion`\n    *** `include-query-response` → `log-query-response`\n  ** Added `TracingAwareLoggingObservationHandler` for trace-aware logging\n  ** Replaced `micrometer-tracing-bridge-otel` with `micrometer-tracing`\n  ** Removed event-based tracing in favor of direct logging\n  ** Removed direct dependency on the OTel SDK\n  ** Renamed `includePrompt` to `logPrompt` in observation properties (in `ChatClientBuilderProperties`, `ChatObservationProperties`, and `ImageObservationProperties`)\n\n==== Chat Memory Repository Module and Autoconfiguration Renaming\n\nWe've standardized the naming pattern for chat memory components by adding the repository suffix throughout the codebase. This change affects Cassandra, JDBC, and Neo4j implementations, impacting artifact IDs, Java package names, and class names for clarity.\n\n==== Artifact IDs\nAll memory-related artifacts now follow a consistent pattern:\n\n* `spring-ai-model-chat-memory-*` → `spring-ai-model-chat-memory-repository-*`\n* `spring-ai-autoconfigure-model-chat-memory-*` → `spring-ai-autoconfigure-model-chat-memory-repository-*`\n* `spring-ai-starter-model-chat-memory-*` → `spring-ai-starter-model-chat-memory-repository-*`\n\n==== Java Packages\n\n* Package paths now include `.repository.` segment\n* Example: `org.springframework.ai.chat.memory.jdbc` → `org.springframework.ai.chat.memory.repository.jdbc`\n\n==== Configuration Classes\n\n* Main autoconfiguration classes now use the `Repository` suffix\n* Example: `JdbcChatMemoryAutoConfiguration` → `JdbcChatMemoryRepositoryAutoConfiguration`\n\n==== Properties\n\n* Configuration properties renamed from `spring.ai.chat.memory.<storage>...` to `spring.ai.chat.memory.repository.<storage>...`\n\n\n**Migration Required:**\n- Update your Maven/Gradle dependencies to use the new artifact IDs.\n- Update any imports, class references, or configuration that used the old package or class names.\n\n==== Message Aggregator Refactoring\n\n===== Changes\n\n* `MessageAggregator` class has been moved from `org.springframework.ai.chat.model` package in the `spring-ai-client-chat` module to the `spring-ai-model` module (same package name)\n* The `aggregateChatClientResponse` method has been removed from `MessageAggregator` and moved to a new class `ChatClientMessageAggregator` in the `org.springframework.ai.chat.client` package\n\n===== Migration Guide\n\nIf you were directly using the `aggregateChatClientResponse` method from `MessageAggregator`, you need to use the new `ChatClientMessageAggregator` class instead:\n\n[source,java]\n----\n// Before\nnew MessageAggregator().aggregateChatClientResponse(chatClientResponses, aggregationHandler);\n\n// After\nnew ChatClientMessageAggregator().aggregateChatClientResponse(chatClientResponses, aggregationHandler);\n----\n\nDon't forget to add the appropriate import:\n\n[source,java]\n----\nimport org.springframework.ai.chat.client.ChatClientMessageAggregator;\n----\n\n==== Watson\nThe Watson AI model was removed as it was based on the older text generation that is considered outdated as there is a new chat generation model available.\nHopefully Watson will reappear in a future version of Spring AI\n\n==== MoonShot and QianFan\n\nMoonshot and Qianfan have been removed since they are not accessible from outside China.  These have been moved to the Spring AI Community repository.\n\n==== Removed Vector Store\n* Removed HanaDB vector store autoconfiguration (https://github.com/spring-projects/spring-ai/commit/f3b46244942c5072c2e2fa89e62cde71c61bbf25[f3b4624])\n\n==== Memory Management\n* Removed CassandraChatMemory implementation (https://github.com/spring-projects/spring-ai/commit/11e3c8f9a6636d77f203968b83625d3e5694c408[11e3c8f])\n* Simplified chat memory advisor hierarchy and removed deprecated API (https://github.com/spring-projects/spring-ai/commit/848a3fd31fadd07c9ba77f6dc30425389d095e9a[848a3fd])\n* Removed deprecations in JdbcChatMemory (https://github.com/spring-projects/spring-ai/commit/356a68f15eea07a040bd27c66442472fc55e6475[356a68f])\n* Refactored chat memory repository artifacts for clarity (https://github.com/spring-projects/spring-ai/commit/2d517eec5cd7ce5f88149b876ed57a06ad353e11[2d517ee])\n* Refactored chat memory repository autoconfigurations and Spring Boot starters for clarity (https://github.com/spring-projects/spring-ai/commit/f6dba1bf083d847cdc07888ba62746683e3d61bb[f6dba1b])\n\n==== Message and Template APIs\n* Removed deprecated UserMessage constructors (https://github.com/spring-projects/spring-ai/commit/06edee406978d172a1f87f4c7b255282f9d55e4c[06edee4])\n* Removed deprecated PromptTemplate constructors (https://github.com/spring-projects/spring-ai/commit/722c77e812f3f3ea40cf2258056fcf1578b15c62[722c77e])\n* Removed deprecated methods from Media (https://github.com/spring-projects/spring-ai/commit/228ef10bfbfe279d7d09f2a7ba166db873372118[228ef10])\n* Refactored StTemplateRenderer: renamed supportStFunctions to validateStFunctions (https://github.com/spring-projects/spring-ai/commit/0e15197298c0848b78a746f3d740191e6a6aee7a[0e15197])\n* Removed left over TemplateRender interface after moving it (https://github.com/spring-projects/spring-ai/commit/52675d854ccecbc702cec24c4f070520eca64938[52675d8])\n\n==== Additional Client API Changes\n* Removed deprecations in ChatClient and Advisors (https://github.com/spring-projects/spring-ai/commit/4fe74d886e26d52abf6f2f5545264d422a0be4b2[4fe74d8])\n* Removed deprecations from OllamaApi and AnthropicApi (https://github.com/spring-projects/spring-ai/commit/46be8987d6bc385bf74b9296aa4308c7a8658d2f[46be898])\n\n==== Package Structure Changes\n* Removed inter-package dependency cycles in spring-ai-model (https://github.com/spring-projects/spring-ai/commit/ebfa5b9b2cc2ab0d20e25dc6128c4b1c9c327f89[ebfa5b9])\n* Moved MessageAggregator to spring-ai-model module (https://github.com/spring-projects/spring-ai/commit/54e5c07428909ceec248e3bbd71e2df4b0812e49[54e5c07])\n\n==== Dependencies\n* Removed unused json-path dependency in spring-ai-openai (https://github.com/spring-projects/spring-ai/commit/9de13d1b2fdb67219dc7afbf319ade789784f2b9[9de13d1])\n\n=== Behavior Changes\n\n==== Azure OpenAI\n* Added Entra ID identity management for Azure OpenAI with clean autoconfiguration (https://github.com/spring-projects/spring-ai/commit/3dc86d33ce90ebd68ec3997a0eb4704ab7774e99[3dc86d3])\n\n=== General Cleanup\n* Removed all code deprecations (https://github.com/spring-projects/spring-ai/commit/76bee8ceb2854839f93a6c52876f50bb24219355[76bee8c]) and (https://github.com/spring-projects/spring-ai/commit/b6ce7f3e4a7aafe6b9031043f63813dde6e73605[b6ce7f3])\n\n[[upgrading-to-1-0-0-m8]]\n== Upgrading to 1.0.0-M8\n\nYou can automate the upgrade process to 1.0.0-M8 using an OpenRewrite recipe.\nThis recipe helps apply many of the necessary code changes for this version.\nFind the recipe and usage instructions at https://github.com/arconia-io/arconia-migrations/blob/main/docs/spring-ai.md[Arconia Spring AI Migrations].\n\n=== Breaking Changes\n\nWhen upgrading from Spring AI 1.0 M7 to 1.0 M8, users who previously registered tool callbacks are encountering breaking changes that cause tool calling functionality to silently fail. This is specifically impacting code that used the deprecated `tools()` method.\n\n==== Example\n\nHere's an example of code that worked in M7 but no longer functions as expected in M8:\n\n[source,java]\n----\n// This worked in M7 but silently fails in M8\nChatClient chatClient = new OpenAiChatClient(api)\n    .tools(List.of(\n        new Tool(\"get_current_weather\", \"Get the current weather in a given location\", \n            new ToolSpecification.ToolParameter(\"location\", \"The city and state, e.g. San Francisco, CA\", true))\n    ))\n    .toolCallbacks(List.of(\n        new ToolCallback(\"get_current_weather\", (toolName, params) -> {\n            // Weather retrieval logic\n            return Map.of(\"temperature\", 72, \"unit\", \"fahrenheit\", \"description\", \"Sunny\");\n        })\n    ));\n----\n\n==== Solution\n\nThe solution is to use the `toolSpecifications()` method instead of the deprecated `tools()` method:\n\n[source,java]\n----\n// This works in M8\nChatClient chatClient = new OpenAiChatClient(api)\n    .toolSpecifications(List.of(\n        new Tool(\"get_current_weather\", \"Get the current weather in a given location\", \n            new ToolSpecification.ToolParameter(\"location\", \"The city and state, e.g. San Francisco, CA\", true))\n    ))\n    .toolCallbacks(List.of(\n        new ToolCallback(\"get_current_weather\", (toolName, params) -> {\n            // Weather retrieval logic\n            return Map.of(\"temperature\", 72, \"unit\", \"fahrenheit\", \"description\", \"Sunny\");\n        })\n    ));\n----\n\n=== Removed

1.0.0-M7 is the last milestone release before the RC1 and GA releases. It introduces several important changes to artifact IDs, package names, and module structure that will be maintained in the final release.\n\n=== Artifact ID, Package, and Module Changes\nThe 1.0.0-M7 includes the same structural changes as 1.0.0-SNAPSHOT.\n\nFor details, refer to:\n- xref:upgrade-notes.adoc#common-artifact-id-changes[Common Artifact ID Changes]\n- xref:upgrade-notes.adoc#common-package-changes[Common Package Changes]\n- xref:upgrade-notes.adoc#common-module-structure[Common Module Structure]\n\n=== MCP Java SDK Upgrade to 0.9.0\n\nSpring AI 1.0.0-M7 now uses MCP Java SDK version 0.9.0, which includes significant changes from previous versions. If you're using MCP in your applications, you'll need to update your code to accommodate these changes.\n\nKey changes include:\n\n==== Interface Renaming\n\n* `ClientMcpTransport` → `McpClientTransport`\n* `ServerMcpTransport` → `McpServerTransport`\n* `DefaultMcpSession` → `McpClientSession` or `McpServerSession`\n* All `*Registration` classes → `*Specification` classes\n\n==== Server Creation Changes\n\n* Use `McpServerTransportProvider` instead of `ServerMcpTransport`\n\n[source,java]\n----\n// Before\nServerMcpTransport transport = new WebFluxSseServerTransport(objectMapper, \"/mcp/message\");\nvar server = McpServer.sync(transport)\n    .serverInfo(\"my-server\", \"1.0.0\")\n    .build();\n\n// After\nMcpServerTransportProvider transportProvider = new WebFluxSseServerTransportProvider(objectMapper, \"/mcp/message\");\nvar server = McpServer.sync(transportProvider)\n    .serverInfo(\"my-server\", \"1.0.0\")\n    .build();\n----\n\n==== Handler Signature Changes\n\nAll handlers now receive an `exchange` parameter as their first argument:\n\n[source,java]\n----\n// Before\n.tool(calculatorTool, args -> new CallToolResult(\"Result: \" + calculate(args)))\n\n// After\n.tool(calculatorTool, (exchange, args) -> new CallToolResult(\"Result: \" + calculate(args)))\n----\n\n==== Client Interaction via Exchange\n\nMethods previously available on the server are now accessed through the exchange object:\n\n[source,java]\n----\n// Before\nClientCapabilities capabilities = server.getClientCapabilities();\nCreateMessageResult result = server.createMessage(new CreateMessageRequest(...));\n\n// After\nClientCapabilities capabilities = exchange.getClientCapabilities();\nCreateMessageResult result = exchange.createMessage(new CreateMessageRequest(...));\n----\n\n==== Roots Change Handlers\n\n[source,java]\n----\n// Before\n.rootsChangeConsumers(List.of(\n    roots -> System.out.println(\"Roots changed: \" + roots)\n))\n\n// After\n.rootsChangeHandlers(List.of(\n    (exchange, roots) -> System.out.println(\"Roots changed: \" + roots)\n))\n----\n\nFor a complete guide to migrating MCP code, refer to the https://github.com/spring-projects/spring-ai/blob/main/spring-ai-docs/src/main/antora/modules/ROOT/pages/mcp-migration.adoc[MCP Migration Guide].\n\n=== Enabling/Disabling Model Auto-Configuration\n\nThe previous configuration properties for enabling/disabling model auto-configuration have been removed:\n\n* `spring.ai.<provider>.chat.enabled`\n* `spring.ai.<provider>.embedding.enabled`\n* `spring.ai.<provider>.image.enabled`\n* `spring.ai.<provider>.moderation.enabled`\n\nBy default, if a model provider (e.g., OpenAI, Ollama) is found on the classpath, its corresponding auto-configuration for relevant model types (chat, embedding, etc.) is enabled. If multiple providers for the same model type are present (e.g., both `spring-ai-openai-spring-boot-starter` and `spring-ai-ollama-spring-boot-starter`), you can use the following properties to select *which* provider's auto-configuration should be active, effectively disabling the others for that specific model type.\n\nTo disable auto-configuration for a specific model type entirely, even if only one provider is present, set the corresponding property to a value that does not match any provider on the classpath (e.g., `none` or `disabled`).\n\nYou can refer to the https://github.com/spring-projects/spring-ai/blob/main/spring-ai-model/src/main/java/org/springframework/ai/model/SpringAIModels.java[`SpringAIModels`] enumeration for a list of well-known provider values.\n\n* `spring.ai.model.audio.speech=<model-provider|none>`\n* `spring.ai.model.audio.transcription=<model-provider|none>`\n* `spring.ai.model.chat=<model-provider|none>`\n* `spring.ai.model.embedding=<model-provider|none>`\n* `spring.ai.model.embedding.multimodal=<model-provider|none>`\n* `spring.ai.model.embedding.text=<model-provider|none>`\n* `spring.ai.model.image=<model-provider|none>`\n* `spring.ai.model.moderation=<model-provider|none>`\n\n=== Automating upgrading using AI\n\nYou can automate the upgrade process to 1.0.0-M7 using the Claude Code CLI tool with a provided prompt:\n\n1. Download the https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/overview[Claude Code CLI tool]\n2. Copy the prompt from the https://github.com/spring-projects/spring-ai/blob/main/src/prompts/update-to-m7.txt[update-to-m7.txt] file\n3. Paste the prompt into the Claude Code CLI\n4. The AI will analyze your project and make the necessary changes\n\nNOTE: The automated upgrade prompt currently handles artifact ID changes, package relocations, and module structure changes, but does not yet include automatic changes for upgrading to MCP 0.9.0. If you're using MCP, you'll need to manually update your code following the guidance in the xref:upgrade-notes.adoc#mcp-java-sdk-upgrade-to-0-9-0[MCP Java SDK Upgrade] section.\n\n[[common-sections]]\n== Common Changes Across Versions\n\n[[common-artifact-id-changes]]\n=== Artifact ID Changes\n\nThe naming pattern for Spring AI starter artifacts has changed.\nYou'll need to update your dependencies according to the following patterns:\n\n* Model starters: `spring-ai-\\{model\\}-spring-boot-starter` → `spring-ai-starter-model-\\{model\\}`\n* Vector Store starters: `spring-ai-\\{store\\}-store-spring-boot-starter` → `spring-ai-starter-vector-store-\\{store\\}`\n* MCP starters: `spring-ai-mcp-\\{type\\}-spring-boot-starter` → `spring-ai-starter-mcp-\\{type\\}`\n\n==== Examples\n\n[tabs]\n======\nMaven::\n+\n[source,xml,indent=0,subs=\"verbatim,quotes\"]\n----\n<!-- BEFORE -->\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-openai-spring-boot-starter</artifactId>\n</dependency>\n\n<!-- AFTER -->\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-model-openai</artifactId>\n</dependency>\n----\n\nGradle::\n+\n[source,groovy,indent=0,subs=\"verbatim,quotes\"]\n----\n// BEFORE\nimplementation 'org.springframework.ai:spring-ai-openai-spring-boot-starter'\nimplementation 'org.springframework.ai:spring-ai-redis-store-spring-boot-starter'\n\n// AFTER\nimplementation 'org.springframework.ai:spring-ai-starter-model-openai'\nimplementation 'org.springframework.ai:spring-ai-starter-vector-store-redis'\n----\n======\n\n==== Changes to Spring AI Autoconfiguration Artifacts\n\nThe Spring AI autoconfiguration has changed from a single monolithic artifact to individual autoconfiguration artifacts per model, vector store, and other components.\nThis change was made to minimize the impact of different versions of dependent libraries conflicting, such as Google Protocol Buffers, Google RPC, and others.\nBy separating autoconfiguration into component-specific artifacts, you can avoid pulling in unnecessary dependencies and reduce the risk of version conflicts in your application.\n\nThe original monolithic artifact is no longer available:\n\n[source,xml,indent=0,subs=\"verbatim,quotes\"]\n----\n<!-- NO LONGER AVAILABLE -->\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-spring-boot-autoconfigure</artifactId>\n    <version>${project.version}</version>\n</dependency>\n----\n\nInstead, each component now has its own autoconfiguration artifact following these patterns:\n\n* Model autoconfiguration: `spring-ai-autoconfigure-model-\\{model\\}`\n* Vector Store autoconfiguration: `spring-ai-autoconfigure-vector-store-\\{store\\}`\n* MCP autoconfiguration: `spring-ai-autoconfigure-mcp-\\{type\\}`\n\n==== Examples of New Autoconfiguration Artifacts\n\n[tabs]\n======\nModels::\n+\n[source,xml,indent=0,subs=\"verbatim,quotes\"]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-autoconfigure-model-openai</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-autoconfigure-model-anthropic</artifactId>\n</dependency>\n----\n\nVector Stores::\n+\n[source,xml,indent=0,subs=\"verbatim,quotes\"]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-autoconfigure-vector-store-redis</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-autoconfigure-vector-store-pgvector</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-autoconfigure-vector-store-chroma</artifactId>\n</dependency>\n----\n\nMCP::\n+\n[source,xml,indent=0,subs=\"verbatim,quotes\"]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-autoconfigure-mcp-client</artifactId>\n</dependency>\n\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-autoconfigure-mcp-server</artifactId>\n</dependency>\n----\n======\n\nNOTE: In most cases, you won't need to explicitly add these autoconfiguration dependencies.\nThey are included transitively when using the corresponding starter dependencies.\n\n[[common-package-changes]]\n=== Package Name Changes\n\nYour IDE should assist with refactoring to the new package locations.\n\n* `KeywordMetadataEnricher` and `SummaryMetadataEnricher` have moved from `org.springframework.ai.transformer` to `org.springframework.ai.chat.transformer`.\n* `Content`, `MediaContent`, and `Media` have moved from `org.springframework.ai.model` to `org.springframework.ai.content`.\n\n[[common-module-structure]]\n=== Module Structure\n\nThe project has undergone significant changes to its module and artifact structure. Previously, `spring-ai-core` contained all central interfaces, but this has now been split into specialized domain modules to reduce unnecessary dependencies in your applications.\n\nimage::spring-ai-dependencies.png[Spring AI Dependencies, width=1000, align=\"center\"]\n\n==== spring-ai-commons\n\nBase module with no dependencies on other Spring AI modules. Contains:\n- Core domain models (`Document`, `TextSplitter`)\n- JSON utilities and resource handling\n- Structured logging and observability support\n\n==== spring-ai-model\n\nProvides AI capability abstractions:\n- Interfaces like `ChatModel`, `EmbeddingModel`, and `ImageModel`\n- Message types and prompt templates\n- Function-calling framework (`ToolDefinition`, `ToolCallback`)\n- Content filtering and observation support\n\n==== spring-ai-vector-store\n\nUnified vector database abstraction:\n- `VectorStore` interface for similarity search\n- Advanced filtering with SQL-like expressions\n- `SimpleVectorStore` for in-memory usage\n- Batching support for embeddings\n\n==== spring-ai-client-chat\n\nHigh-level conversational AI APIs:\n- `ChatClient` interface\n- Conversation persistence via `ChatMemory`\n- Response conversion with `OutputConverter`\n- Advisor-based interception\n- Synchronous and reactive streaming support\n\n==== spring-ai-advisors-vector-store\n\nBridges chat with vector stores for RAG:\n- `QuestionAnswerAdvisor`: injects context into prompts\n- `VectorStoreChatMemoryAdvisor`: stores/retrieves conversation history\n\n==== spring-ai-model-chat-memory-cassandra\n\nApache Cassandra persistence for `ChatMemory`:\n- `CassandraChatMemory` implementation\n- Type-safe CQL with Cassandra's QueryBuilder\n==== spring-ai-model-chat-memory-neo4j\n\nNeo4j graph database persistence for chat conversations.\n\n==== spring-ai-rag\n\nComprehensive framework for Retrieval Augmented Generation:\n- Modular architecture for RAG pipelines\n- `RetrievalAugmentationAdvisor` as main entry point\n- Functional programming principles with composable components\n\n=== Dependency Structure\n\nThe dependency hierarchy can be summarized as:\n\n* `spring-ai-commons` (foundation)\n* `spring-ai-model` (depends on commons)\n* `spring-ai-vector-store` and `spring-ai-client-chat` (both depend on model)\n* `spring-ai-advisors-vector-store` and `spring-ai-rag` (depend on both client-chat and vector-store)\n* `spring-ai-model-chat-memory-*` modules (depend on client-chat)\n\n[[common-toolcontext-changes]]\n=== ToolContext Changes\n\nThe `ToolContext` class has been enhanced to support both explicit and implicit tool resolution. Tools can now be:\n\n1. **Explicitly Included**: Tools that are explicitly requested in the prompt and included in the call to the model.\n2. **Implicitly Available**: Tools that are made available for runtime dynamic resolution, but never included in any call to the model unless explicitly requested.\n\nStarting with 1.0.0-M7, tools are only included in the call to the model if they are explicitly requested in the prompt or explicitly included in the call.\n\nAdditionally, the `ToolContext` class has now been marked as final and cannot be extended anymore. It was never supposed to be subclassed. You can add all the contextual data you need when instantiating a `ToolContext`, in the form of a `Map<String, Object>`. For more information, check the [documentation](https://docs.spring.io/spring-ai/reference/api/tools.html#_tool_context).\n\n[[upgrading-to-1-0-0-m6]]\n== Upgrading to 1.0.0-M6\n\n=== Changes to Usage Interface and DefaultUsage Implementation\n\nThe `Usage` interface and its default implementation `DefaultUsage` have undergone the following changes:\n\n1. Method Rename:\n* `getGenerationTokens()` is now `getCompletionTokens()`\n\n2. Type Changes:\n* All token count fields in `DefaultUsage` changed from `Long` to `Integer`:\n** `promptTokens`\n** `completionTokens` (formerly `generationTokens`)\n** `totalTokens`\n\n==== Required Actions\n\n* Replace all calls to `getGenerationTokens()` with `getCompletionTokens()`\n\n* Update `DefaultUsage` constructor calls:\n[source,java]\n----\n// Old (M5)\nnew DefaultUsage(Long promptTokens, Long generationTokens, Long totalTokens)\n\n// New (M6)\nnew DefaultUsage(Integer promptTokens, Integer completionTokens, Integer totalTokens)\n----\n\nNOTE: For more information on handling Usage, refer xref:api/usage-handling.adoc[here]\n\n==== JSON Ser/Deser changes\nWhile M6 maintains backward compatibility for JSON deserialization of the `generationTokens` field, this field will be removed in M7. Any persisted JSON documents using the old field name should be updated to use `completionTokens`.\n\nExample of the new JSON format:\n[source,json]\n----\n{\n  \"promptTokens\": 100,\n  \"completionTokens\": 50,\n  \"totalTokens\": 150\n}\n----\n\n=== Changes to usage of FunctionCallingOptions for tool calling\n\nEach `ChatModel` instance, at construction time, accepts an optional `ChatOptions` or `FunctionCallingOptions` instance\nthat can be used to configure default tools used for calling the model.\n\nBefore 1.0.0-M6:\n\n- any tool passed via the `functions()` method of the default `FunctionCallingOptions` instance was included in\neach call to the model from that `ChatModel` instance, possibly overwritten by runtime options.\n- any tool passed via the `functionCallbacks()` method of the default `FunctionCallingOptions` instance was only\nmade available for runtime dynamic resolution (see xref:api/tools.adoc#_tool_resolution[Tool Resolution]), but never\nincluded in any call to the model unless explicitly requested.\n\nStarting 1.0.0-M6:\n\n- any tool passed via the `functions()` method or the `functionCallbacks()` of the default `FunctionCallingOptions`\ninstance is now handled in the same way: it is included in each call to the model from that `ChatModel` instance,\npossibly overwritten by runtime options. With that, there is consistency in the way tools are included in calls\nto the model and prevents any confusion due to a difference in behavior between `functionCallbacks()` and all the other options.\n\nIf you want to make a tool available for runtime dynamic resolution and include it in a chat request to the model only\nwhen explicitly requested, you can use one of the strategies described in xref:api/tools.adoc#_tool_resolution[Tool Resolution].\n\nNOTE: 1.0.0-M6 introduced new APIs for handling tool calling. Backward compatibility is maintained for the old APIs across\nall scenarios, except the one described above. The old APIs are still available, but they are deprecated\nand will be removed in 1.0.0-M7.\n\n=== Removal of deprecated Amazon Bedrock chat models\n\nStarting 1.0.0-M6, Spring AI transitioned to using Amazon Bedrock's Converse API for all Chat conversation implementations in Spring AI.\nAll the Amazon Bedrock Chat models are removed except the Embedding models for Cohere and Titan.\n\nNOTE: Refer to xref:api/chat/bedrock-converse.adoc[Bedrock Converse] documentation for using the chat models.\n\n=== Changes to use Spring Boot 3.4.2 for dependency management\n\nSpring AI updates to use Spring Boot 3.4.2 for the dependency management. You can refer https://github.com/spring-projects/spring-boot/blob/v3.4.2/spring-boot-project/spring-boot-dependencies/build.gradle[here] for the dependencies managed by Spring Boot 3.4.2\n\n==== Required Actions\n\n* If you are upgrading to Spring Boot 3.4.2, please make sure to refer to https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.4-Release-Notes#upgrading-from-spring-boot-33[this] documentation for the changes required to configure the REST Client. Notably, if you don’t have an HTTP client library on the classpath, this will likely result in the use of `JdkClientHttpRequestFactory` where `SimpleClientHttpRequestFactory` would have been used previously. To switch to use `SimpleClientHttpRequestFactory`, you need to set `spring.http.client.factory=simple`.\n* If you are using a different version of Spring Boot (say Spring Boot 3.3.x) and need a specific version of a dependency, you can override it in your build configuration.\n\n=== Vector Store API changes\n\nIn version 1.0.0-M6, the `delete` method in the `VectorStore` interface has been modified to be a void operation instead of returning an `Optional<Boolean>`.\nIf your code previously checked the return value of the delete operation, you'll need to remove this check.\nThe operation now throws an exception if the deletion fails, providing more direct error handling.\n\n==== Before 1.0.0-M6:\n[source,java]\n----\nOptional<Boolean> result = vectorStore.delete(ids);\nif (result.isPresent() && result.get()) {\n    // handle successful deletion\n}\n----\n\n==== In 1.0.0-M6 and later:\n[source,java]\n----\nvectorStore.delete(ids);\n// deletion successful if no exception is thrown\n----\n\n== Upgrading to 1.0.0.M5\n\n* Vector Builders have been refactored for consistency.\n* Current VectorStore implementation constructors have been deprecated, use the builder pattern.\n* VectorStore implementation packages have been moved into unique package names, avoiding conflicts across artifact.  For example `org.springframework.ai.vectorstore` to `org.springframework.ai.pgvector.vectorstore`.\n\n== Upgrading to 1.0.0.RC3\n\n* The type of the portable chat options (`frequencyPenalty`, `presencePenalty`, `temperature`, `topP`) has been changed from `Float` to `Double`.\n\n== Upgrading to 1.0.0.M2\n\n* The configuration prefix for the Chroma Vector Store has been changes from `spring.ai.vectorstore.chroma.store` to `spring.ai.vectorstore.chroma` in order to align with the naming conventions of other vector stores.\n\n* The default value of the `initialize-schema` property on vector stores capable of initializing a schema is now set to `false`.\nThis implies that the applications now need to explicitly opt-in for schema initialization on supported vector stores, if the schema is expected to be created at application startup.\nNot all vector stores support this property.\nSee the corresponding vector store documentation for more details.\nThe following are the vector stores that currently don't support the `initialize-schema` property.\n\n1. Hana\n2. Pinecone\n3. Weaviate\n\n* In Bedrock Jurassic 2, the chat options `countPenalty`, `frequencyPenalty`, and `presencePenalty`\nhave been renamed to `countPenaltyOptions`, `frequencyPenaltyOptions`, and `presencePenaltyOptions`.\nFurthermore, the type of the chat option `stopSequences` have been changed from `String[]` to `List<String>`.\n\n* In Azure OpenAI, the type of the chat options `frequencyPenalty` and `presencePenalty`\nhas been changed from `Double` to `Float`, consistently with all the other implementations.\n\n== Upgrading to 1.0.0.M1\n\nOn our march to release 1.0.0 M1 we have made several breaking changes.  Apologies, it is for the best!\n\n=== ChatClient changes\n\nA major change was made that took the 'old' `ChatClient` and moved the functionality into `ChatModel`.  The 'new' `ChatClient` now takes an instance of `ChatModel`. This was done to support a fluent API for creating and executing prompts in a style similar to other client classes in the Spring ecosystem, such as `RestClient`, `WebClient`, and `JdbcClient`.  Refer to the [JavaDoc](https://docs.spring.io/spring-ai/docs/api) for more information on the Fluent API, proper reference documentation is coming shortly.\n\nWe renamed the 'old' `ModelClient` to `Model` and renamed implementing classes, for example `ImageClient` was renamed to `ImageModel`.  The `Model` implementation represents the portability layer that converts between the Spring AI API and the underlying AI Model API.\n\nA new package `model` that contains interfaces and base classes to support creating AI Model Clients for any input/output data type combination. At the moment, the chat and image model packages implement this. We will be updating the embedding package to this new model soon.\n\nA new \"portable options\" design pattern. We wanted to provide as much portability in the `ModelCall` as possible across different chat based AI Models. There is a common set of generation options and then those that are specific to a model provider. A sort of \"duck typing\" approach is used. `ModelOptions` in the model package is a marker interface indicating implementations of this class will provide the options for a model. See `ImageOptions`, a subinterface that defines portable options across all text->image `ImageModel` implementations. Then `StabilityAiImageOptions` and `OpenAiImageOptions` provide the options specific to each model provider. All options classes are created via a fluent API builder, all can be passed into the portable `ImageModel` API. These option data types are used in autoconfiguration/configuration properties for the `ImageModel` implementations.\n\n=== Artifact name changes\n\nRenamed POM artifact names:\n- spring-ai-qdrant -> spring-ai-qdrant-store\n- spring-ai-cassandra -> spring-ai-cassandra-store\n- spring-ai-pinecone -> spring-ai-pinecone-store\n- spring-ai-redis -> spring-ai-redis-store\n- spring-ai-qdrant -> spring-ai-qdrant-store\n- spring-ai-gemfire -> spring-ai-gemfire-store\n- spring-ai-azure-vector-store-spring-boot-starter -> spring-ai-azure-store-spring-boot-starter\n- spring-ai-redis-spring-boot-starter -> spring-ai-starter-vector-store-redis\n\n== Upgrading to 0.8.1\n\nFormer `spring-ai-vertex-ai` has been renamed to `spring-ai-vertex-ai-palm2` and `spring-ai-vertex-ai-spring-boot-starter` has been renamed to `spring-ai-vertex-ai-palm2-spring-boot-starter`.\n\nSo, you need to change the dependency from\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-vertex-ai</artifactId>\n</dependency>\n----\n\nTo\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-vertex-ai-palm2</artifactId>\n</dependency>\n----\n\nand the related Boot starter for the Palm2 model has changed from\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-vertex-ai-spring-boot-starter</artifactId>\n</dependency>\n----\n\nto\n\n[source,xml]\n----\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-vertex-ai-palm2-spring-boot-starter</artifactId>\n</dependency>\n----\n\n* Renamed Classes (01.03.2024)\n\n** VertexAiApi -> VertexAiPalm2Api\n** VertexAiClientChat -> VertexAiPalm2ChatClient\n** VertexAiEmbeddingClient -> VertexAiPalm2EmbeddingClient\n** VertexAiChatOptions -> VertexAiPalm2ChatOptions\n\n== Upgrading to 0.8.0\n\n=== January 24, 2024 Update\n\n* Moving the `prompt` and `messages` and `metadata` packages to subpackages of `org.springframework.ai.chat`\n* New functionality is *text to image* clients. Classes are `OpenAiImageModel` and `StabilityAiImageModel`. See the integration tests for usage, docs are coming soon.\n* A new package `model` that contains interfaces and base classes to support creating AI Model Clients for any input/output data type combination. At the moment, the chat and image model packages implement this. We will be updating the embedding package to this new model soon.\n* A new \"portable options\" design pattern. We wanted to provide as much portability in the `ModelCall` as possible across different chat based AI Models.

    "content": "# Model Context Protocol (MCP) Server\n\nThe Spring AI MCP module provides integration with the Model Context Protocol, allowing you to expose your AI tools and resources through a standardized protocol. This module is particularly useful when you want to make your Spring AI tools and resources available to MCP-compatible clients.\n\n## Dependencies\n\nTo use the MCP server functionality, add the following dependency to your project:\n\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-mcp-server</artifactId>\n    <version>${spring-ai.version}</version>\n</dependency>\n```\n\n## Configuration Properties\n\nThe MCP server can be configured using the following properties under the `spring.ai.mcp.server` prefix:\n\n| Property | Default | Description |\n|----------|---------|-------------|\n| `enabled` | `false` | Enable/disable the MCP server |\n| `name` | `\"mcp-server\"` | Name of the MCP server |\n| `version` | `\"1.0.0\"` | Version of the MCP server |\n| `type` | `SYNC` | Server type (`SYNC` or `ASYNC`) |\n| `resource-change-notification` | `true` | Enable/disable resource change notifications |\n| `tool-change-notification` | `true` | Enable/disable tool change notifications |\n| `prompt-change-notification` | `true` | Enable/disable prompt change notifications |\n| `transport` | `STDIO` | Transport type (`STDIO`, `WEBMVC`, or `WEBFLUX`) |\n| `sse-message-endpoint` | `\"/mcp/message\"` | Server-Sent Events (SSE) message endpoint for web transports |\n\n## Server Types\n\nThe MCP server supports two operation modes:\n\n### 1. Synchronous Mode (Default)\n\nThe synchronous mode is the default option, suitable for most use cases where tools and resources are accessed sequentially:\n\n```yaml\nspring:\n  ai:\n    mcp:\n      server:\n        type: SYNC\n```\n\n### 2. Asynchronous Mode\n\nThe asynchronous mode is designed for reactive applications and scenarios requiring non-blocking operations:\n\n```yaml\nspring:\n  ai:\n    mcp:\n      server:\n        type: ASYNC\n```\n\n## Transport Options\n\nThe MCP server supports three transport types:\n\n### 1. STDIO Transport (Default)\n\nThe Standard Input/Output transport is the default option, suitable for command-line tools and local development:\n\n```yaml\nspring:\n  ai:\n    mcp:\n      server:\n        transport: STDIO\n```\n\n### 2. WebMvc Transport\n\nThe WebMvc transport uses Spring MVC's Server-Sent Events (SSE) for communication:\n\n```yaml\nspring:\n  ai:\n    mcp:\n      server:\n        transport: WEBMVC\n        sse-message-endpoint: /mcp/message  # Optional, defaults to /mcp/message\n```\n\nRequired dependencies:\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>mcp-spring-webmvc</artifactId>\n</dependency>\n<dependency>\n    <groupId>org.springframework.boot</groupId>\n    <artifactId>spring-boot-starter-web</artifactId>\n</dependency>\n```\n\n### 3. WebFlux Transport\n\nThe WebFlux transport uses Spring WebFlux's Server-Sent Events for reactive communication:\n\n```yaml\nspring:\n  ai:\n    mcp:\n      server:\n        transport: WEBFLUX\n        sse-message-endpoint: /mcp/message  # Optional, defaults to /mcp/message\n```\n\nRequired dependencies:\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>mcp-spring-webflux</artifactId>\n</dependency>\n<dependency>\n    <groupId>org.springframework.boot</groupId>\n    <artifactId>spring-boot-starter-webflux</artifactId>\n</dependency>\n```\n\n## Core Features\n\nThe MCP server provides several core features:\n\n### Tools\n\n- Extensible tool registration system supporting both sync and async execution\n- Automatic tool discovery and registration through Spring's component scanning\n- Change notification support for tool updates\n\n### Resources\n\n- Static and dynamic resource management\n- Optional change notifications for resource updates\n- Support for both sync and async resource access\n\n### Prompts\n\n- Configurable prompt templates\n- Change notification support for template updates\n- Integration with Spring AI's prompt system\n\n## Usage Example\n\nHere's an example of configuring the MCP server with WebMvc transport and custom settings:\n\n```yaml\nspring:\n  ai:\n    mcp:\n      server:\n        enabled: true\n        name: \"My AI Tools Server\"\n        version: \"1.0.0\"\n        type: SYNC\n        transport: WEBMVC\n        sse-message-endpoint: /ai/mcp/events\n        resource-change-notification: true\n        tool-change-notification: true\n        prompt-change-notification: false\n```\n\n## Auto-configuration\n\nThe MCP server auto-configuration is provided through:\n\n1. `McpServerAutoConfiguration`: Core server configuration supporting both sync and async modes\n2. `McpWebMvcServerAutoConfiguration`: WebMvc transport configuration (activated when WebMvc dependencies are present)\n3. `McpWebFluxServerAutoConfiguration`: WebFlux transport configuration (activated when WebFlux dependencies are present)\n\nThe auto-configuration will automatically set up the appropriate server type and transport based on your configuration and available dependencies.\n\n## Implementing Tools and Resources\n\nTo expose your Spring AI tools and resources through the MCP server:\n\n1. Implement the `ToolCallback` interface for your AI tools:\n```java\n@Component\npublic class MyAiTool implements ToolCallback {\n    // Implementation\n}\n```\n\n2. The auto-configuration will automatically discover and register your tools with the MCP server, converting them to either sync or async implementations based on your server type configuration.\n\n## Monitoring\n\nThe MCP server provides notifications for changes in:\n- Tools (when tools are added or removed)\n- Resources (when resources are updated)\n- Prompts (when prompt templates change)\n\nYou can enable/disable these notifications using the configuration properties. The notification system works with both sync and async server types, providing consistent change tracking regardless of the chosen operation mode.\n"

    "content": "# Anacletus and Birba's Quest for the Loch of the Stars\n\n## Chapter 1: The Map and the Adventure\n\nOnce upon a time, in a cozy little cottage nestled at the edge of the Scottish Highlands, lived an owl named Anacletus and a curious cat named Birba. Anacletus was wise and careful, always reading maps and planning things thoroughly, while Birba was lively and adventurous, always ready to chase after the next interesting thing. Despite their differences, they were the best of friends and loved going on little adventures together.\n\n## Chapter 2: The Journey Begins\n\nOne sunny morning, Anacletus showed Birba an old, crinkled map he’d found in the attic. “Look, Birba,” he said, pointing with his feathery wing. “This map leads to the legendary Loch of the Stars. They say it shines brighter than any other lake at night.” Birba’s eyes sparkled with excitement. “Oh, we have to go there!” she meowed. So, they packed a small bag with snacks, a compass, and a flashlight, and off they went, eager to find the legendary loch.\n\n## Chapter 3: The Highland Adventure\n\nTheir journey began with a climb up the rolling hills covered in purple heather. Anacletus flapped his wings, soaring ahead to scout for any obstacles, while Birba trotted along below, her nose sniffing the air for interesting scents. Soon, they came across a bubbling brook. Anacletus carefully flew over it, but Birba hesitated. “Just a little jump!” Anacletus called out. With a deep breath, Birba leaped and landed safely on the other side. She purred proudly, and they continued on their way.\n\n## Chapter 4: The Highland Cows and the Hidden Path\n\nAs they ventured deeper into the Highlands, they stumbled upon a herd of curious Highland cows with long, shaggy hair. The cows mooed softly, and one of them named Fergus approached. “Where are you two headed?” Fergus asked. “We’re searching for the Loch of the Stars!” Anacletus replied. Fergus nodded knowingly and pointed his nose north. “Follow the path by the big stones, and it will lead you closer to the loch,” he said. Thanking Fergus, they set off again, Birba occasionally stopping to bat at the fluttering butterflies along the way.\n\n## Chapter 5: The Mysterious Forest and the Deer Family\n\nThe day wore on, and they soon found themselves in a mysterious forest. Tall, ancient pine trees surrounded them, casting long shadows. “Stay close, Birba,” Anacletus whispered, his wise eyes scanning for any sign of danger. But Birba had already darted after a flicker of light, thinking it was a firefly. Anacletus sighed and followed her until they came to a hidden glade where a family of deer grazed quietly. The smallest fawn looked up and gave them a curious nod before they moved along.\n\n## Chapter 6: The Loch of the Stars\n\nAfter a while, the sun began to set, painting the sky in shades of pink and gold. Anacletus decided it was a good time to rest. They found a cozy hollow at the base of a tree, where they shared the snacks they’d packed. Birba munched on her fish treats while Anacletus nibbled on a biscuit. “Do you think we’ll find the Loch of the Stars?” Birba asked, her eyes twinkling. “I think so,” Anacletus replied with a wise smile. “We’re getting closer.”\n\n## Chapter 7: The Shimmering Loch\n\nAs night fell, they finally reached the top of a hill where they could see a shimmering light in the distance. “Look, Birba!” Anacletus hooted excitedly. There, nestled among the hills, was the Loch of the Stars, gleaming like a sky full of stars. The two friends hurried down to the water’s edge, marveling at how the loch sparkled under the moonlight, casting a gentle glow all around.\n\n## Chapter 8: The Magic of the Loch\n\nBirba dipped a curious paw into the water, causing ripples that sent stars dancing across the surface. “It’s beautiful!” she gasped. Anacletus nodded, his heart filled with awe. They spent the night by the loch, watching the shimmering stars reflected in the water, feeling as though they were surrounded by magic.\n\n## Chapter 9: The Journey Home\n\nWhen dawn broke, the shimmering loch returned to its quiet, glassy calm. With a satisfied yawn, Birba stretched and said, “That was the best adventure yet.” Anacletus agreed, feeling a warmth in his feathers as they turned back toward home, carrying memories of the Loch of the Stars in their hearts.\n\n## Chapter 10: The End of the Adventure\n\nAnd as they made their way back to their cozy cottage, they already started dreaming of their next big adventure—because Anacletus and Birba knew that the Scottish Highlands held endless wonders for those who dared to explore.\n"

Spring              Framework                         Overview\n\n\n            Spring makes it easy to create Java enterprise applications. It provides everything you need to\n            embrace    the  Java   language    in  an  enterprise    environment,      with   support   for  Groovy    and   Kotlin   as\n            alternative languages on the JVM, and with the flexibility to create many kinds of architectures\n            depending     on  an  application’s    needs.  As  of  Spring   Framework      5.1, Spring   requires    JDK  8+  (Java  SE\n            8+) and provides out-of-the-box support for JDK 11 LTS. Java SE 8 update 60 is suggested as the\n            minimum      patch  release   for Java  8, but  it is  generally  recommended       to  use a  recent  patch   release.\n\n            Spring  supports    a wide   range   of application    scenarios.   In  a large  enterprise,   applications    often  exist\n            for a  long  time   and   have   to run   on  a  JDK  and   application    server   whose    upgrade     cycle  is beyond\n            developer    control.   Others   may    run  as  a single   jar with   the  server   embedded,      possibly   in  a cloud\n            environment.      Yet others   may    be standalone     applications    (such   as  batch   or integration    workloads)\n            that do  not  need   a server.\n\n\n            Spring  is open   source.   It  has  a large  and active  community      that  provides   continuous     feedback    based\n            on a  diverse   range  of  real-world   use  cases.  This  has  helped    Spring  to  successfully   evolve   over  a  very\n            long  time.\n\n            1.1.    What          We      Mean          by    \"Spring\"\n\n\n            The  term   \"Spring\"   means    different   things  in  different   contexts.  It can  be  used   to refer  to the  Spring\n            Framework      project   itself,  which  is where    it  all  started.  Over time,  other  Spring   projects   have   been\n            built on  top  of  the Spring    Framework.      Most   often,  when    people   say  \"Spring\",   they  mean    the  entire\n            family  of  projects.  This  reference    documentation       focuses   on  the foundation:     the  Spring   Framework\n            itself.\n\n\n            The  Spring   Framework      is divided   into  modules.    Applications     can  choose   which    modules    they  need.\n            At the heart are the modules of the core container, including a configuration model and a\n            dependency injection mechanism. Beyond that, the Spring Framework provides foundational\n            support    for   different    application     architectures,     including    messaging,      transactional     data   and\n            persistence, and web. It also includes the Servlet-based Spring MVC web framework and, in\n            parallel, the  Spring   WebFlux     reactive   web   framework.\n\n\n            A note about modules: Spring’s framework jars allow for deployment to JDK 9’s module path\n            (\"Jigsaw\"). For use in Jigsaw-enabled applications, the Spring Framework 5 jars come with\n            \"Automatic-Module-Name\" manifest entries which define stable language-level module names\n            (\"spring.core\",   \"spring.context\",     etc.) independent     from    jar artifact  names    (the  jars follow   the  same\n            naming    pattern   with   \"-\" instead   of  \".\",  e.g.  \"spring-core\"  and   \"spring-context\").    Of  course,   Spring’s\n            framework     jars  keep  working    fine  on  the  classpath   on  both  JDK  8  and  9+.\n\n            1.2.    History            of   Spring          and       the      Spring          Framework\n\n\n            Spring came into being in 2003 as a response to the complexity of the early J2EE specifications.\n            While   some    consider   Java   EE  and   its modern-day      successor    Jakarta   EE  to  be  in  competition     with\n            Spring, they are in fact complementary. The Spring programming model does not embrace the\n            Jakarta    EE   platform      specification;    rather,    it  integrates     with    carefully    selected    individual\n\n            specifications   from   the  traditional   EE  umbrella:\n\n\n              • Servlet  API   (JSR 340)\n\n              • WebSocket     API  (JSR  356)\n\n              • Concurrency      Utilities (JSR  236)\n\n              • JSON   Binding    API  (JSR 367)\n\n              • Bean   Validation   (JSR  303)\n\n              • JPA  (JSR  338)\n\n              • JMS   (JSR 914)\n\n              • as well  as  JTA/JCA   setups  for  transaction    coordination,    if necessary.\n\n\n            The  Spring   Framework      also  supports    the Dependency       Injection   (JSR 330)  and   Common      Annotations\n            (JSR 250) specifications, which application developers may choose to use instead of the Spring-\n            specific  mechanisms      provided     by the  Spring   Framework.       Originally,  those   were   based   on  common\n            javax  packages.\n\n            As  of Spring   Framework       6.0, Spring   has  been   upgraded     to  the Jakarta   EE   9 level  (e.g. Servlet   5.0+,\n            JPA  3.0+), based    on  the  jakarta   namespace      instead   of the  traditional   javax   packages.    With   EE  9  as\n            the  minimum      and   EE  10  supported     already,   Spring   is prepared     to provide    out-of-the-box     support\n            for the further evolution of the Jakarta EE APIs. Spring Framework 6.0 is fully compatible with\n            Tomcat   10.1,  Jetty 11  and  Undertow     2.3  as web   servers,   and  also  with  Hibernate    ORM    6.1.\n\n\n            Over   time,  the role  of  Java/Jakarta    EE  in application    development      has  evolved.    In the  early  days   of\n            J2EE  and   Spring,  applications    were   created   to  be deployed     to an  application    server.  Today,   with  the\n            help  of Spring   Boot,   applications    are  created   in a  devops-   and   cloud-friendly     way,  with   the  Servlet\n            container   embedded      and   trivial  to change.   As  of  Spring   Framework      5, a  WebFlux     application    does\n            not  even   use  the  Servlet   API  directly   and   can  run   on  servers   (such   as  Netty)  that  are  not   Servlet\n            containers.\n\n\n            Spring  continues    to  innovate   and   to evolve.  Beyond     the Spring   Framework,      there  are  other   projects,\n            such as Spring Boot, Spring Security, Spring Data, Spring Cloud, Spring Batch, among others. It’s\n            important to remember that each project has its own source code repository, issue tracker, and\n            release  cadence.    See  spring.io/projects    for the  complete    list of Spring   projects.\n\n            1.3.    Design           Philosophy\n\n\n            When you learn about a framework, it’s important to know not only what it does but what\n            principles   it  follows. Here  are  the  guiding   principles   of the  Spring   Framework:\n\n\n              • Provide choice at every level. Spring lets you defer design decisions as late as possible. For\n                example, you can switch persistence providers through configuration without changing your\n                code.  The   same   is true  for  many   other   infrastructure     concerns    and  integration    with  third-party\n                APIs.\n\n              • Accommodate diverse perspectives. Spring embraces flexibility and is not opinionated about\n                how things should be done. It supports a wide range of application needs with different\n                perspectives.\n\n              • Maintain strong backward compatibility. Spring’s evolution has been carefully managed to\n                force  few   breaking    changes    between    versions.   Spring    supports   a  carefully   chosen   range   of  JDK\n                versions and third-party libraries to facilitate maintenance of applications and libraries that\n                depend    on  Spring.\n\n              • Care   about  API   design.  The  Spring   team   puts   a lot of thought   and   time  into  making    APIs  that  are\n                intuitive  and   that  hold  up  across  many    versions   and   many    years.\n\n              • Set high standards for code quality. The Spring Framework puts a strong emphasis on\n                meaningful,     current,   and   accurate    javadoc.   It is one   of very   few  projects   that  can   claim   clean\n                code   structure   with  no  circular   dependencies     between     packages.\n\n            1.4.    Feedback               and       Contributions\n\n\n            For how-to questions or diagnosing or debugging issues, we suggest using Stack Overflow. Click\n            here  for  a list of the  suggested    tags  to use  on  Stack   Overflow.    If  you’re fairly  certain   that there   is a\n            problem    in the  Spring   Framework      or would    like to suggest   a feature,   please  use  the  GitHub    Issues.\n\n            If you have a solution in mind or a suggested fix, you can submit a pull request on Github.\n            However,    please   keep   in mind    that, for  all but  the  most   trivial issues,  we  expect   a  ticket to  be  filed\n            in the issue  tracker,   where   discussions    take  place  and   leave  a record   for  future  reference.\n\n\n            For more    details  see the  guidelines    at the CONTRIBUTING,         top-level  project  page.\n\n            1.5.    Getting           Started\n\n\n            If  you are  just getting   started   with  Spring,   you  may    want   to begin   using   the  Spring   Framework      by\n            creating a Spring Boot-based application. Spring Boot provides a quick (and opinionated) way to\n            create a production-ready Spring-based application. It is based on the Spring Framework, favors\n            convention    over   configuration,    and  is designed    to get  you  up  and  running    as  quickly  as  possible.\n\n\n            You  can  use  start.spring.io    to generate    a basic  project   or follow   one  of  the  \"Getting   Started\"  guides,\n            such as Getting Started Building a RESTful Web Service. As well as being easier to digest, these\n            guides   are  very   task  focused,   and   most   of them    are  based   on   Spring   Boot.  They   also   cover   other\n            projects from the Spring portfolio that you might want to consider when solving a particular\n            problem.\n\n            Chapter                2.    Core           Technologies\n\n\n            This  part  of the  reference    documentation       covers   all  the  technologies   that  are  absolutely   integral   to\n            the Spring   Framework.\n\n\n            Foremost    amongst    these   is  the  Spring Framework’s      Inversion    of Control   (IoC)  container.   A  thorough\n            treatment    of the  Spring   Framework’s      IoC  container    is closely  followed    by  comprehensive       coverage\n            of Spring’s   Aspect-Oriented      Programming        (AOP)   technologies.    The   Spring   Framework       has  its own\n            AOP framework, which is conceptually easy to understand and which successfully addresses the\n            80%   sweet  spot  of AOP   requirements      in Java   enterprise   programming.\n\n\n            Coverage of Spring’s integration with AspectJ (currently the richest — in terms of features — and\n            certainly  most   mature    AOP   implementation       in the  Java  enterprise   space)   is also provided.\n\n\n            AOT processing can be used to optimize your application ahead-of-time. It is typically used for\n            native  image   deployment      using  GraalVM.\n\n            2.1.    The       IoC      Container\n\n\n            This  chapter   covers   Spring’s  Inversion    of Control   (IoC)  container.\n\n\n            2.1.1.   Introduction          to  the   Spring      IoC   Container        and    Beans\n\n            This chapter covers the Spring Framework implementation of the Inversion of Control (IoC)\n            principle. IoC is also known as dependency injection (DI). It is a process whereby objects define\n            their dependencies      (that  is, the other   objects   they  work   with)   only  through    constructor    arguments,\n            arguments to a factory method, or properties that are set on the object instance after it is\n            constructed or returned from a factory method. The container then injects those dependencies\n            when   it creates   the  bean.  This   process   is fundamentally      the  inverse   (hence   the  name,    Inversion    of\n            Control) of the bean itself controlling the instantiation or location of its dependencies by using\n            direct  construction    of classes  or  a mechanism      such   as the  Service  Locator    pattern.\n\n\n            The  org.springframework.beans         and   org.springframework.context         packages     are  the  basis  for  Spring\n            Framework’s       IoC   container.     The   BeanFactory      interface    provides     an   advanced      configuration\n            mechanism capable of managing any type of object. ApplicationContext is a sub-interface of\n            BeanFactory.   It adds:\n\n\n              • Easier   integration   with  Spring’s   AOP   features\n\n              • Message    resource    handling    (for use  in internationalization)\n\n              • Event   publication\n\n              • Application-layer       specific    contexts    such     as  the    WebApplicationContext         for   use   in   web\n                applications.\n\n\n            In short, the BeanFactory provides the configuration framework and basic functionality, and the\n            ApplicationContext       adds    more     enterprise-specific      functionality.     The    ApplicationContext        is  a\n            complete superset of the BeanFactory and is used exclusively in this chapter in descriptions of\n            Spring’s    IoC   container.     For    more     information      on    using    the   BeanFactory      instead    of   the\n\n            ApplicationContext,      see  the  section  covering    the BeanFactory    API.\n\n\n            In Spring, the objects that form the backbone of your application and that are managed by the\n            Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and\n            managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your\n            application.   Beans,   and   the dependencies      among     them,   are  reflected   in the  configuration    metadata\n            used  by  a container.\n\n\n            2.1.2.   Container        Overview\n\n            The  org.springframework.context.ApplicationContext                interface   represents    the  Spring   IoC  container\n            and  is responsible     for instantiating,    configuring,    and   assembling     the  beans.   The  container    gets  its\n            instructions on what objects to instantiate, configure, and assemble by reading configuration\n            metadata.    The  configuration     metadata     is  represented   in  XML,   Java  annotations,    or  Java  code.  It lets\n            you express the objects that compose your application and the rich interdependencies between\n            those  objects.\n\n\n            Several implementations of the ApplicationContext interface are supplied with Spring. In stand-\n            alone applications, it is common to create an instance of ClassPathXmlApplicationContext or\n            FileSystemXmlApplicationContext.           While     XML     has   been     the   traditional    format     for   defining\n            configuration metadata, you can instruct the container to use Java annotations or code as the\n            metadata    format   by  providing    a small   amount    of XML    configuration    to  declaratively   enable    support\n            for these  additional    metadata    formats.\n\n\n            In most application scenarios, explicit user code is not required to instantiate one or more\n            instances   of a  Spring   IoC  container.    For  example,    in a  web   application    scenario,   a simple   eight   (or\n            so) lines  of boilerplate    web   descriptor    XML    in the  web.xml    file of the  application    typically   suffices\n            (see Convenient     ApplicationContext       Instantiation    for Web    Applications).    If you  use  the  Spring   Tools\n            for Eclipse   (an  Eclipse-powered       development      environment),      you   can  easily  create   this  boilerplate\n            configuration    with   a few  mouse    clicks  or keystrokes.\n\n\n            The  following    diagram    shows    a high-level    view   of how   Spring    works.   Your   application    classes  are\n            combined with configuration metadata so that, after the ApplicationContext is created and\n            initialized,  you  have   a fully configured    and   executable    system   or  application.\n\n            Figure  1.  The  Spring IoC container\n\n\n            Configuration      Metadata\n\n            As the preceding diagram shows, the Spring IoC container consumes a form of configuration\n            metadata. This configuration metadata represents how you, as an application developer, tell the\n            Spring  container    to instantiate,   configure,   and   assemble    the  objects  in your   application.\n\n\n            Configuration metadata is traditionally supplied in a simple and intuitive XML format, which is\n            what   most  of  this chapter   uses  to convey    key  concepts    and  features   of the  Spring   IoC container.\n\n\n                              XML-based     metadata     is not  the  only  allowed    form   of configuration     metadata.     The\n                              Spring IoC container itself is totally decoupled from the format in which this\n                             configuration metadata is actually written. These days, many developers choose\n                              Java-based    configuration    for  their  Spring  applications.\n\n\n            For information     about   using   other  forms   of metadata     with  the  Spring   container,   see:\n\n\n              • Annotation-based         configuration:       Spring     2.5   introduced      support      for   annotation-based\n                configuration     metadata.\n\n              • Java-based configuration: Starting with Spring 3.0, many features provided by the Spring\n                JavaConfig project became part of the core Spring Framework. Thus, you can define beans\n                external to your application classes by using Java rather than XML files. To use these new\n                features,   see the  @Configuration,     @Bean,  @Import,  and   @DependsOn   annotations.\n\n            Spring   configuration     consists  of  at least  one   and  typically   more    than  one   bean   definition   that  the\n            container must manage. XML-based configuration metadata configures these beans as <bean/>\n            elements inside a top-level <beans/> element. Java configuration typically uses @Bean-annotated\n            methods    within   a @Configuration     class.\n\n            These   bean   definitions    correspond     to the  actual   objects   that  make   up   your   application.   Typically,\n            you define service layer objects, data access objects (DAOs), presentation objects such as Struts\n            Action instances, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so\n            forth. Typically,   one   does  not  configure    fine-grained     domain    objects   in the  container,    because    it  is\n\n            usually   the responsibility    of  DAOs   and   business    logic  to create  and   load  domain     objects.  However,\n            you  can   use  Spring’s   integration    with  AspectJ    to configure    objects   that  have   been   created   outside\n            the control   of an  IoC  container.

In particular, Resource paths are used to construct applications\n                              contexts,  as  described    in Application    Contexts   and   Resource    Paths.\n\n\n            The  following   example     shows   the  service   layer  objects  (services.xml)     configuration     file:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <!--   services    -->\n\n\n                    <bean   id=\"petStore\"\n              class=\"org.springframework.samples.jpetstore.services.PetStoreServiceImpl\">\n                         <property     name=\"accountDao\"        ref=\"accountDao\"/>\n                         <property     name=\"itemDao\"       ref=\"itemDao\"/>\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      for  services     go  here   -->\n\n\n              </beans>\n\n\n\n            The  following   example     shows   the  data  access   objects  daos.xml   file:\n\n\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"accountDao\"\n                         class=\"org.springframework.samples.jpetstore.dao.jpa.JpaAccountDao\">\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <bean   id=\"itemDao\"\n              class=\"org.springframework.samples.jpetstore.dao.jpa.JpaItemDao\">\n                         <!--   additional     collaborators       and  configuration      for   this   bean   go  here   -->\n                    </bean>\n\n\n                    <!--   more   bean  definitions      for  data   access    objects    go  here   -->\n\n\n              </beans>\n\n            In the  preceding    example,     the  service  layer   consists  of  the  PetStoreServiceImpl       class and   two   data\n            access objects of the types JpaAccountDao and JpaItemDao (based on the JPA Object-Relational\n            Mapping    standard).    The  property    name  element    refers  to the  name   of  the JavaBean     property,   and  the\n            ref element refers to the name of another bean definition. This linkage between id and ref\n            elements expresses the dependency between collaborating objects. For details of configuring an\n            object’s  dependencies,     see  Dependencies.\n\n\n\n            Composing    XML-based    Configuration   Metadata\n\n            It can be useful to have bean definitions span multiple XML files. Often, each individual XML\n            configuration    file represents    a logical  layer  or module     in your  architecture.\n\n\n            You can use the application context constructor to load bean definitions from all these XML\n            fragments.    This  constructor    takes  multiple   Resource   locations,   as was   shown    in the  previous    section.\n            Alternatively,   use  one   or more    occurrences     of the  <import/>    element    to load   bean   definitions   from\n            another   file or files. The  following    example    shows    how   to do  so:\n\n\n\n              <beans>\n                    <import    resource=\"services.xml\"/>\n                    <import    resource=\"resources/messageSource.xml\"/>\n                    <import    resource=\"/resources/themeSource.xml\"/>\n\n\n                    <bean   id=\"bean1\"     class=\"...\"/>\n                    <bean   id=\"bean2\"     class=\"...\"/>\n              </beans>\n\n\n\n            In the preceding example, external bean definitions are loaded from three files: services.xml,\n            messageSource.xml,      and  themeSource.xml.      All location   paths   are   relative  to  the  definition   file doing\n            the importing,    so  services.xml    must    be in  the same    directory   or  classpath   location   as  the file doing\n            the importing,     while  messageSource.xml       and  themeSource.xml      must   be  in  a resources    location   below\n            the  location   of the  importing     file.  As  you can  see,  a leading    slash  is ignored.   However,     given   that\n            these  paths   are  relative,  it is better  form   not  to  use  the  slash  at all. The  contents    of the  files being\n            imported,    including   the  top  level  <beans/>   element,    must   be  valid  XML    bean   definitions,   according\n            to the Spring   Schema.\n\n                              It  is  possible,  but  not  recommended,     to reference    files in parent   directories   using   a\n                              relative \"../\" path. Doing so creates a dependency on a file that is outside the\n                              current    application.     In   particular,    this   reference     is  not   recommended          for\n                              classpath: URLs (for example, classpath:../services.xml), where the runtime\n                              resolution process chooses the “nearest” classpath root and then looks into its\n                              parent directory. Classpath configuration changes may lead to the choice of a\n                              different,  incorrect   directory.\n                \n                              You  can  always    use  fully qualified    resource   locations   instead   of  relative  paths:   for\n                              example,        file:C:/config/services.xml             or     classpath:/config/services.xml.\n                              However, be aware that you are coupling your application’s configuration to\n                              specific  absolute   locations.   It  is  generally  preferable  to keep   an indirection    for such\n                              absolute locations — for example, through \"${…}\" placeholders that are resolved\n                              against  JVM   system   properties    at runtime.\n\n\n            The  namespace      itself provides    the  import   directive   feature.  Further    configuration     features   beyond\n            plain bean definitions are available in a selection of XML namespaces provided by Spring — for\n            example,    the context   and   util  namespaces.\n\n\n\n            The Groovy   Bean   Definition  DSL\n\n            As a further example for externalized configuration metadata, bean definitions can also be\n            expressed    in Spring’s   Groovy    Bean   Definition    DSL,  as known     from   the  Grails  framework.     Typically,\n            such  configuration     live in a \".groovy\"    file  with the structure   shown    in  the following    example:\n\n\n\n              beans    {\n                    dataSource(BasicDataSource)           {\n                         driverClassName       =  \"org.hsqldb.jdbcDriver\"\n                         url   =  \"jdbc:hsqldb:mem:grailsDB\"\n                         username     = \"sa\"\n                         password     = \"\"\n                         settings     = [mynew:\"setting\"]\n                    }\n                    sessionFactory(SessionFactory)            {\n                         dataSource     =  dataSource\n                    }\n                    myService(MyService)         {\n                         nestedBean     =  {  AnotherBean     bean   ->\n                               dataSource     =  dataSource\n                         }\n                    }\n              }\n\n\n\n            This  configuration     style  is largely  equivalent     to XML    bean   definitions    and  even   supports    Spring’s\n            XML   configuration     namespaces.      It also  allows   for importing     XML    bean   definition   files through    an\n            importBeans    directive.\n\n            Using   the  Container\n\n            The  ApplicationContext      is the  interface   for an  advanced     factory  capable    of maintaining     a registry   of\n            different beans and their dependencies. By using the method T getBean(String name, Class<T>\n            requiredType),    you  can  retrieve   instances   of  your  beans.\n\n            The  ApplicationContext       lets you   read   bean   definitions   and   access   them,   as  the  following    example\n            shows:\n\n\n            Java\n\n\n              //  create    and   configure    beans\n              ApplicationContext        context    =  new   ClassPathXmlApplicationContext(\"services.xml\",\n              \"daos.xml\");\n\n\n              //  retrieve     configured     instance\n              PetStoreService       service    =  context.getBean(\"petStore\",            PetStoreService.class);\n\n\n              //  use   configured     instance\n              List<String>      userList     = service.getUsernameList();\n\n\n\n            Kotlin\n\n\n              import    org.springframework.beans.factory.getBean\n\n\n              //  create    and   configure    beans\n              val   context    =  ClassPathXmlApplicationContext(\"services.xml\",                  \"daos.xml\")\n\n\n              //  retrieve     configured     instance\n              val   service    =  context.getBean<PetStoreService>(\"petStore\")\n\n\n              //  use   configured     instance\n              var   userList    =  service.getUsernameList()\n\n\n\n            With    Groovy     configuration,      bootstrapping       looks    very    similar.   It  has    a   different    context\n            implementation class which is Groovy-aware (but also understands XML bean definitions). The\n            following   example    shows    Groovy    configuration:\n\n\n            Java\n\n\n              ApplicationContext        context    =  new   GenericGroovyApplicationContext(\"services.groovy\",\n              \"daos.groovy\");\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericGroovyApplicationContext(\"services.groovy\",                    \"daos.groovy\")\n\n\n\n            The  most   flexible  variant   is GenericApplicationContext         in  combination     with   reader   delegates — for\n            example,    with  XmlBeanDefinitionReader        for XML    files,  as  the  following example    shows:\n\n            Java\n\n\n              GenericApplicationContext           context    =  new  GenericApplicationContext();\n              new   XmlBeanDefinitionReader(context).loadBeanDefinitions(\"services.xml\",                           \"daos.xml\");\n              context.refresh();\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericApplicationContext()\n              XmlBeanDefinitionReader(context).loadBeanDefinitions(\"services.xml\",                           \"daos.xml\")\n              context.refresh()\n\n\n\n            You  can  also  use  the GroovyBeanDefinitionReader         for Groovy    files, as the  following   example     shows:\n\n\n            Java\n\n\n              GenericApplicationContext           context    =  new  GenericApplicationContext();\n              new   GroovyBeanDefinitionReader(context).loadBeanDefinitions(\"services.groovy\",\n              \"daos.groovy\");\n              context.refresh();\n\n\n\n            Kotlin\n\n\n              val   context    =  GenericApplicationContext()\n              GroovyBeanDefinitionReader(context).loadBeanDefinitions(\"services.groovy\",\n              \"daos.groovy\")\n              context.refresh()\n\n\n\n            You can mix and match such reader delegates on the same ApplicationContext, reading bean\n            definitions   from   diverse  configuration     sources.\n\n\n            You  can  then  use  getBean   to retrieve   instances    of your  beans.   The  ApplicationContext       interface   has  a\n            few  other   methods    for  retrieving   beans,   but,  ideally, your   application    code   should   never   use  them.\n            Indeed,   your  application    code   should   have   no  calls to  the getBean()    method    at  all  and thus  have   no\n            dependency      on Spring   APIs   at all.  For  example,  Spring’s   integration    with  web   frameworks      provides\n            dependency     injection   for  various   web   framework     components      such   as controllers    and  JSF-managed\n            beans, letting you declare a dependency on a specific bean through metadata (such as an\n            autowiring    annotation).\n\n\n            2.1.3.   Bean     Overview\n\n            A Spring   IoC  container    manages    one   or more    beans.  These   beans   are  created   with   the configuration\n            metadata    that  you  supply   to the  container    (for example,    in the  form   of XML   <bean/>   definitions).\n\n\n            Within   the  container    itself,  these bean   definitions   are  represented     as BeanDefinition     objects,   which\n            contain   (among    other  information)     the  following   metadata:\n\n              • A package-qualified class name: typically, the actual implementation class of the bean being\n\n                defined.\n\n              • Bean behavioral configuration elements, which state how the bean should behave in the\n                container    (scope,  lifecycle  callbacks,   and  so  forth).\n\n              • References     to other  beans   that  are  needed    for the  bean   to do  its work.  These   references    are  also\n                called  collaborators    or  dependencies.\n\n              • Other   configuration     settings   to set  in the  newly    created   object — for    example,    the  size  limit  of\n                the  pool  or the  number     of connections     to use  in a bean   that  manages    a  connection    pool.\n\n\n            This metadata translates to a set of properties that make up each bean definition. The following\n            table describes    these  properties:\n\n\n            Table 1. The  bean  definition\n\n            Property                                                       Explained     in…\n\n            Class                                                          Instantiating   Beans\n\n            Name                                                           Naming    Beans\n\n            Scope                                                          Bean   Scopes\n\n            Constructor     arguments                                      Dependency      Injection\n\n            Properties                                                     Dependency      Injection\n\n            Autowiring     mode                                            Autowiring     Collaborators\n\n            Lazy   initialization   mode                                   Lazy-initialized    Beans\n\n            Initialization   method                                        Initialization   Callbacks\n\n            Destruction     method                                         Destruction    Callbacks\n\n\n            In addition to bean definitions that contain information on how to create a specific bean, the\n            ApplicationContext      implementations       also  permit   the  registration   of existing   objects  that  are  created\n            outside the container (by users). This is done by accessing the ApplicationContext’s BeanFactory\n            through      the     getBeanFactory()        method,       which      returns      the    DefaultListableBeanFactory\n            implementation.          DefaultListableBeanFactory            supports       this     registration       through       the\n            registerSingleton(..)        and    registerBeanDefinition(..)          methods.     However,      typical   applications\n            work   solely  with  beans   defined   through    regular   bean   definition   metadata.\n\n\n                              Bean   metadata    and   manually    supplied    singleton   instances   need   to be  registered    as\n                              early  as possible,   in order   for  the container    to properly    reason    about   them   during\n                              autowiring    and   other  introspection     steps.  While   overriding    existing   metadata    and\n                             existing  singleton    instances    is supported    to  some    degree,   the  registration   of  new\n                              beans at runtime (concurrently with live access to the factory) is not officially\n                              supported    and   may   lead  to  concurrent    access   exceptions,    inconsistent    state  in the\n                              bean  container,    or both.\n\n\n\n            Naming     Beans\n\n            Every   bean   has  one  or  more   identifiers.  These   identifiers   must   be  unique    within   the container    that\n            hosts  the  bean.   A bean   usually   has   only  one   identifier.  However,     if it  requires  more   than   one,  the\n\n            extra  ones  can  be  considered     aliases.\n\n\n            In XML-based      configuration    metadata,    you   use  the  id attribute,  the  name  attribute,  or  both  to specify\n            the  bean   identifiers.  The   id  attribute   lets you   specify  exactly   one   id. Conventionally,     these   names\n            are  alphanumeric      ('myBean',    'someService',    etc.), but  they  can  contain    special  characters    as  well. If\n            you  want    to introduce    other   aliases  for  the  bean,   you  can   also  specify  them    in the  name   attribute,\n            separated    by  a comma     (,), semicolon     (;), or white   space.   As  a historical   note,  in  versions   prior   to\n            Spring   3.1,  the  id  attribute  was defined   as  an xsd:ID   type,  which   constrained     possible   characters.   As\n            of 3.1, it is defined as an xsd:string type. Note that bean id uniqueness is still enforced by the\n            container,   though   no  longer   by  XML   parsers.\n\n\n            You  are  not  required   to supply    a name  or an  id for  a bean.   If  you do not  supply   a  name  or id explicitly,\n            the container    generates    a unique    name    for that  bean.  However,     if you  want   to refer  to  that bean   by\n            name, through the use of the ref element or a Service Locator style lookup, you must provide a\n            name. Motivations for not supplying a name are related to using inner beans and autowiring\n            collaborators.\n\n\n                                                    Bean     Naming        Conventions\n\n               The   convention     is  to  use  the  standard Java  convention     for  instance   field names    when    naming\n               beans. That is, bean names start with a lowercase letter and are camel-cased from there.\n               Examples     of such   names    include   accountManager,    accountService,     userDao,   loginController,     and\n               so  forth.\n\n\n               Naming     beans   consistently    makes    your   configuration     easier  to read   and   understand.     Also,  if\n               you   use  Spring  AOP,   it  helps a lot when   applying    advice   to a set of beans    related  by  name.\n\n\n\n\n                              With component scanning in the classpath, Spring generates bean names for\n                              unnamed     components,      following    the rules  described    earlier:  essentially,   taking  the\n                              simple   class  name    and  turning    its  initial  character  to lower-case.    However,     in the\n                             (unusual)    special  case   when    there  is more    than   one   character    and  both   the  first\n                              and  second   characters    are  upper   case,  the  original  casing   gets preserved.    These   are\n                              the same    rules  as  defined   by  java.beans.Introspector.decapitalize            (which    Spring\n                              uses  here).\n\n\n\n            Aliasing a Bean   outside  the Bean  Definition\n\n            In a bean definition itself, you can supply more than one name for the bean, by using a\n            combination     of up  to  one  name    specified   by  the id  attribute  and   any  number     of other   names    in the\n            name attribute. These names can be equivalent aliases to the same bean and are useful for some\n            situations, such as letting each component in an application refer to a common dependency by\n            using  a bean   name    that is specific  to that  component      itself.\n\n            Specifying all aliases where the bean is actually defined is not always adequate, however. It is\n            sometimes     desirable   to  introduce    an  alias  for a  bean   that  is defined   elsewhere.     This  is commonly\n            the case in large systems where configuration is split amongst each subsystem, with each\n            subsystem     having   its own   set  of object   definitions.   In XML-based      configuration     metadata,    you   can\n            use the  <alias/>   element    to accomplish     this. The  following    example    shows    how   to do  so:\n\n              <alias    name=\"fromName\"       alias=\"toName\"/>\n\n\n\n            In this case, a bean (in the same container) named fromName may also, after the use of this alias\n            definition,  be  referred   to as  toName.\n\n\n            For example,     the configuration     metadata    for  subsystem     A may   refer  to a  DataSource     by the  name    of\n            subsystemA-dataSource.       The  configuration     metadata     for  subsystem     B  may   refer  to a  DataSource     by\n            the name of subsystemB-dataSource. When composing the main application that uses both these\n            subsystems,    the  main   application    refers  to the  DataSource     by  the name    of myApp-dataSource.     To  have\n            all three names refer to the same object, you can add the following alias definitions to the\n            configuration    metadata:\n\n\n\n              <alias    name=\"myApp-dataSource\"          alias=\"subsystemA-dataSource\"/>\n              <alias    name=\"myApp-dataSource\"          alias=\"subsystemB-dataSource\"/>\n\n\n\n            Now   each   component      and  the  main   application    can   refer  to the  dataSource    through    a  name   that  is\n            unique   and   guaranteed      not  to clash   with  any   other   definition   (effectively   creating   a  namespace),\n            yet they  refer  to the  same   bean.\n\n\n                                                           Java-configuration\n\n               If you   use  Javaconfiguration,      the  @Bean  annotation     can   be used   to  provide   aliases.  See   Using\n               the  @Bean  Annotation     for details.\n\n\n\n\n            Instantiating    Beans\n\n            A bean   definition   is essentially   a recipe   for creating   one   or more   objects.   The  container    looks  at the\n            recipe for a named bean when asked and uses the configuration metadata encapsulated by that\n            bean  definition   to  create  (or acquire)   an  actual   object.\n\n\n            If  you use  XML-based      configuration     metadata,    you  specify   the  type  (or  class) of  object  that  is to be\n            instantiated   in  the class  attribute   of the  <bean/>   element.    This  class  attribute   (which,   internally,  is a\n            Class   property      on   a   BeanDefinition      instance)     is  usually    mandatory.       (For   exceptions,     see\n            Instantiation    by  Using   an  Instance   Factory    Method    and   Bean   Definition    Inheritance.)    You   can  use\n            the Class  property    in one   of two  ways:\n\n\n              • Typically, to specify the bean class to be constructed in the case where the container itself\n                directly creates the bean by calling its constructor reflectively, somewhat equivalent to Java\n                code   with  the  new operator.\n\n              • To specify the actual class containing the static factory method that is invoked to create the\n                object,  in the  less common      case  where    the  container    invokes   a static   factory   method    on  a class\n                to create   the  bean.   The  object   type  returned    from    the invocation     of the  static   factory   method\n                may   be  the same    class or  another   class  entirely.\n\n                                                          Nested      class    names\n\n               If you   want   to configure    a  bean   definition   for  a nested   class,  you  may    use  either  the  binary\n               name    or the  source   name    of the  nested   class.\n\n\n               For example, if you have a class called SomeThing in the com.example package, and this\n               SomeThing    class  has  a static   nested   class  called  OtherThing,    they  can   be  separated    by  a dollar\n               sign ($) or a dot (.). So the value of the class attribute in a bean definition would be\n               com.example.SomeThing$OtherThing           or com.example.SomeThing.OtherThing.\n\n\n\n\n\n            Instantiation  with  a Constructor\n\n            When you create a bean by the constructor approach, all normal classes are usable by and\n            compatible    with   Spring.  That   is,  the  class  being developed    does   not  need   to implement     any   specific\n            interfaces or to be coded in a specific fashion. Simply specifying the bean class should suffice.\n            However,     depending     on  what    type  of  IoC  you  use   for that  specific   bean,   you  may    need   a default\n            (empty)   constructor.\n\n\n            The  Spring   IoC  container    can  manage     virtually   any  class  you  want   it to manage.     It  is  not  limited  to\n            managing true JavaBeans. Most Spring users prefer actual JavaBeans with only a default (no-\n            argument) constructor and appropriate setters and getters modeled after the properties in the\n            container.   You   can  also  have   more   exotic  non-bean-style      classes  in  your  container.    If,  for  example,\n            you need to use a legacy connection pool that absolutely does not adhere to the JavaBean\n            specification,   Spring   can  manage    it as well.\n\n\n            With  XML-based      configuration     metadata    you  can   specify  your   bean   class as follows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\"/>\n\n\n              <bean    name=\"anotherExample\"         class=\"examples.ExampleBeanTwo\"/>\n\n\n\n            For details about the mechanism for supplying arguments to the constructor (if required) and\n            setting  object  instance   properties    after the  object  is constructed,    see  Injecting  Dependencies.\n\n\n\n            Instantiation  with  a Static Factory  Method\n\n            When    defining   a bean   that  you  create  with   a static factory   method,    use  the class   attribute  to specify\n            the class  that  contains   the  static   factory   method    and   an  attribute   named    factory-method     to specify\n            the name of the factory method itself. You should be able to call this method (with optional\n            arguments,     as described    later)  and   return   a live  object,  which    subsequently     is treated   as  if it had\n            been  created    through    a constructor.    One   use  for such   a bean   definition   is to call static   factories   in\n            legacy  code.\n\n\n            The  following    bean   definition   specifies   that  the  bean   will  be  created   by  calling   a factory   method.\n            The definition does not specify the type (class) of the returned object, but rather the class\n            containing the factory method. In this example, the createInstance() method must be a static\n            method.   The   following   example     shows   how   to specify   a factory   method:\n\n              <bean    id=\"clientService\"\n                    class=\"examples.ClientService\"\n                    factory-method=\"createInstance\"/>\n\n\n\n            The  following   example     shows   a class  that  would   work    with  the  preceding    bean   definition:\n\n\n            Java\n\n\n              public    class   ClientService      {\n                    private    static   ClientService       clientService      =  new  ClientService();\n                    private    ClientService()       {}\n\n\n                    public   static    ClientService      createInstance()        {\n                         return    clientService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ClientService      private    constructor()      {\n                    companion     object   {\n                         private    val   clientService      =  ClientService()\n                         @JvmStatic\n                         fun   createInstance()       =  clientService\n                    }\n              }\n\n\n\n            For details about the mechanism for supplying (optional) arguments to the factory method and\n            setting  object   instance   properties    after  the  object   is returned    from   the  factory,   see  Dependencies\n            and  Configuration     in Detail.\n\n\n\n            Instantiation  by Using  an  Instance  Factory  Method\n\n            Similar to instantiation through a static factory method, instantiation with an instance factory\n            method    invokes    a non-static   method     of an  existing   bean   from   the  container    to create   a new   bean.\n            To  use  this mechanism,      leave   the  class   attribute  empty    and,   in the  factory-bean     attribute,  specify\n            the name of a bean in the current (or parent or ancestor) container that contains the instance\n            method    that  is  to  be  invoked to  create  the  object.  Set the  name    of the  factory   method    itself with  the\n            factory-method     attribute.  The  following    example    shows    how   to configure    such  a bean:\n\n              <!--   the   factory    bean,   which   contains     a method    called    createInstance()       -->\n              <bean    id=\"serviceLocator\"        class=\"examples.DefaultServiceLocator\">\n                    <!--   inject   any   dependencies      required    by  this   locator    bean   -->\n              </bean>\n\n\n              <!--   the   bean   to  be  created    via  the   factory    bean   -->\n              <bean    id=\"clientService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createClientServiceInstance\"/>\n\n\n\n            The  following   example     shows   the  corresponding      class:\n\n\n            Java\n\n\n              public    class   DefaultServiceLocator         {\n\n\n                    private    static   ClientService       clientService      =  new  ClientServiceImpl();\n\n\n                    public   ClientService       createClientServiceInstance()            {\n                         return    clientService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    DefaultServiceLocator         {\n                    companion     object   {\n                         private    val   clientService      =  ClientServiceImpl()\n                    }\n                    fun  createClientServiceInstance():             ClientService      {\n                         return    clientService\n                    }\n              }\n\n\n\n            One  factory   class can   also hold   more   than  one   factory  method,    as the  following    example    shows:\n\n\n\n              <bean    id=\"serviceLocator\"        class=\"examples.DefaultServiceLocator\">\n                    <!--   inject   any   dependencies      required    by  this   locator    bean   -->\n              </bean>\n\n\n              <bean    id=\"clientService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createClientServiceInstance\"/>\n\n\n              <bean    id=\"accountService\"\n                    factory-bean=\"serviceLocator\"\n                    factory-method=\"createAccountServiceInstance\"/>\n\n            The  following   example     shows   the  corresponding      class:\n\n\n            Java\n\n\n              public    class   DefaultServiceLocator         {\n\n\n                    private    static   ClientService       clientService      =  new  ClientServiceImpl();\n\n\n                    private    static   AccountService       accountService       = new   AccountServiceImpl();\n\n\n                    public   ClientService       createClientServiceInstance()            {\n                         return    clientService;\n                    }\n\n\n                    public   AccountService       createAccountServiceInstance()             {\n                         return    accountService;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    DefaultServiceLocator         {\n                    companion     object   {\n                         private    val   clientService      =  ClientServiceImpl()\n                         private    val   accountService      =  AccountServiceImpl()\n                    }\n\n\n                    fun  createClientServiceInstance():             ClientService      {\n                         return    clientService\n                    }\n\n\n                    fun  createAccountServiceInstance():             AccountService       {\n                         return    accountService\n                    }\n              }\n\n\n\n            This approach shows that the factory bean itself can be managed and configured through\n            dependency     injection   (DI). See  Dependencies      and   Configuration     in Detail.\n\n\n                              In Spring   documentation,       \"factory   bean\"   refers  to a  bean   that is configured     in the\n                              Spring container and that creates objects through an instance or static factory\n                             method. By contrast, FactoryBean (notice the capitalization) refers to a Spring-\n                              specific  FactoryBean    implementation       class.\n\n\n\n            Determining    a Bean’s Runtime    Type\n\n            The runtime type of a specific bean is non-trivial to determine. A specified class in the bean\n            metadata    definition   is just  an  initial class  reference,    potentially   combined      with  a  declared   factory\n            method    or being   a  FactoryBean    class which    may   lead  to  a different   runtime    type  of the  bean,   or not\n\n            being set at all in case of an instance-level factory method (which is resolved via the specified\n            factory-bean name instead). Additionally, AOP proxying may wrap a bean instance with an\n            interface-based     proxy   with   limited  exposure     of the  target   bean’s  actual   type  (just  its implemented\n            interfaces).\n\n            The recommended way to find out about the actual runtime type of a particular bean is a\n            BeanFactory.getType      call  for the  specified   bean   name.   This   takes  all of the  above   cases   into account\n            and  returns   the  type   of object   that a  BeanFactory.getBean       call is going   to return   for  the  same   bean\n            name.\n\n            2.1.4.   Dependencies\n\n            A typical  enterprise    application    does   not  consist  of a  single  object  (or  bean   in the  Spring   parlance).\n            Even   the  simplest   application    has   a few   objects   that  work   together    to present    what   the  end-user\n            sees  as a  coherent    application.    This  next  section   explains    how   you   go  from   defining   a  number     of\n            bean  definitions    that stand   alone  to  a fully realized   application    where   objects   collaborate    to achieve\n            a goal.\n\n\n            Dependency       Injection\n\n            Dependency      injection   (DI) is a process   whereby     objects  define   their  dependencies      (that is, the  other\n            objects  with  which    they  work)   only  through    constructor    arguments,     arguments     to a factory   method,\n            or properties    that  are  set  on  the  object  instance    after  it  is  constructed  or  returned    from   a factory\n            method. The container then injects those dependencies when it creates the bean. This process is\n            fundamentally      the  inverse   (hence   the  name,   Inversion    of  Control)   of the  bean   itself controlling   the\n            instantiation   or  location  of  its  dependencies    on  its own   by  using  direct  construction    of  classes  or the\n            Service  Locator    pattern.\n\n\n            Code   is cleaner   with  the  DI  principle,   and   decoupling    is more    effective  when    objects   are  provided\n            with their dependencies. The object does not look up its dependencies and does not know the\n            location   or class  of  the  dependencies.      As  a result,  your   classes   become    easier   to test, particularly\n            when the dependencies are on interfaces or abstract base classes, which allow for stub or mock\n            implementations       to be used   in unit  tests.\n\n\n            DI  exists   in   two    major    variants:    Constructor-based        dependency       injection    and    Setter-based\n            dependency     injection.\n\n\n\n            Constructor-based    Dependency     Injection\n\n            Constructor-based DI is accomplished by the container invoking a constructor with a number of\n            arguments,      each   representing      a  dependency.       Calling   a   static   factory    method     with    specific\n            arguments to construct the bean is nearly equivalent, and this discussion treats arguments to a\n            constructor    and  to  a static   factory  method     similarly.  The  following    example    shows    a class  that  can\n            only  be dependency-injected        with  constructor     injection:\n\n            Java\n\n\n              public    class   SimpleMovieLister        {\n\n\n                    //  the  SimpleMovieLister        has   a dependency      on  a MovieFinder\n                    private    final   MovieFinder      movieFinder;\n\n\n                    //  a  constructor     so  that   the   Spring   container     can   inject   a  MovieFinder\n                    public   SimpleMovieLister(MovieFinder             movieFinder)      {\n                         this.movieFinder        = movieFinder;\n                    }\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Kotlin\n\n\n              //  a  constructor      so  that   the  Spring    container     can  inject    a MovieFinder\n              class    SimpleMovieLister(private          val   movieFinder:      MovieFinder)      {\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Notice that there is nothing special about this class. It is a POJO that has no dependencies on\n            container   specific  interfaces,   base   classes, or  annotations.\n\n\n            Constructor     Argument      Resolution\n\n            Constructor argument resolution matching occurs by using the argument’s type. If no potential\n            ambiguity exists in the constructor arguments of a bean definition, the order in which the\n            constructor    arguments     are  defined    in a bean   definition    is the order   in  which   those   arguments     are\n            supplied   to the  appropriate     constructor    when   the  bean   is being   instantiated.   Consider    the following\n            class:\n\n\n            Java\n\n\n              package    x.y;\n\n\n              public    class   ThingOne     {\n\n\n                    public   ThingOne(ThingTwo        thingTwo,     ThingThree     thingThree)      {\n                         //  ...\n                    }\n              }\n\n            Kotlin\n\n\n              package    x.y\n\n\n              class    ThingOne(thingTwo:        ThingTwo,    thingThree:      ThingThree)\n\n\n\n            Assuming that the ThingTwo and ThingThree classes are not related by inheritance, no potential\n            ambiguity    exists.  Thus,  the  following    configuration     works    fine, and   you  do  not  need   to  specify  the\n            constructor    argument     indexes   or types   explicitly  in the  <constructor-arg/>      element.\n\n\n\n              <beans>\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\">\n                         <constructor-arg        ref=\"beanTwo\"/>\n                         <constructor-arg        ref=\"beanThree\"/>\n                    </bean>\n\n\n                    <bean   id=\"beanTwo\"      class=\"x.y.ThingTwo\"/>\n\n\n                    <bean   id=\"beanThree\"       class=\"x.y.ThingThree\"/>\n              </beans>\n\n\n\n            When    another   bean   is referenced,    the  type  is known,    and  matching     can  occur   (as was   the case   with\n            the preceding example). When a simple type is used, such as <value>true</value>, Spring cannot\n            determine    the  type  of  the  value,  and  so  cannot   match    by  type  without    help.  Consider    the following\n            class:\n\n\n            Java\n\n\n              package    examples;\n\n\n              public    class   ExampleBean      {\n\n\n                    //  Number    of  years   to  calculate     the  Ultimate     Answer\n                    private    final   int   years;\n\n\n                    //  The  Answer    to  Life,   the   Universe,     and  Everything\n                    private    final   String    ultimateAnswer;\n\n\n                    public   ExampleBean(int       years,    String    ultimateAnswer)       {\n                         this.years     =  years;\n                         this.ultimateAnswer         =  ultimateAnswer;\n                    }\n              }\n\n            Kotlin\n\n\n              package    examples\n\n\n              class    ExampleBean(\n                    private    val  years:    Int,   //  Number    of  years   to  calculate     the  Ultimate     Answer\n                    private    val  ultimateAnswer:       String    //  The   Answer   to  Life,    the  Universe,     and\n              Everything\n              )\n\n\n\n            Constructor   argument    type  matching\n            In the  preceding    scenario,    the  container    can  use  type  matching     with   simple   types  if you   explicitly\n            specify  the  type  of  the  constructor    argument     by  using   the  type  attribute,  as  the  following    example\n            shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       type=\"int\"     value=\"7500000\"/>\n                    <constructor-arg       type=\"java.lang.String\"          value=\"42\"/>\n              </bean>\n\n\n\n            Constructor   argument    index\n            You can use the index attribute to specify explicitly the index of constructor arguments, as the\n            following   example    shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       index=\"0\"     value=\"7500000\"/>\n                    <constructor-arg       index=\"1\"     value=\"42\"/>\n              </bean>\n\n\n\n            In addition to resolving the ambiguity of multiple simple values, specifying an index resolves\n            ambiguity    where    a constructor    has  two  arguments     of  the same    type.\n\n                             The  index   is  0-based.\n\n\n            Constructor   argument    name\n            You can also use the constructor parameter name for value disambiguation, as the following\n            example    shows:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <constructor-arg       name=\"years\"      value=\"7500000\"/>\n                    <constructor-arg       name=\"ultimateAnswer\"         value=\"42\"/>\n              </bean>\n\n\n\n            Keep   in mind    that, to  make   this  work   out  of  the  box,  your   code  must    be  compiled    with   the  debug\n            flag enabled    so that  Spring   can  look   up  the parameter     name    from   the  constructor.    If you  cannot    or\n\n            do not  want   to  compile   your   code   with  the  debug   flag, you   can  use  the  @ConstructorProperties         JDK\n            annotation to explicitly name your constructor arguments. The sample class would then have to\n            look  as follows:\n\n\n            Java\n\n\n              package    examples;\n\n\n              public    class   ExampleBean      {\n\n\n                    //  Fields    omitted\n\n\n                    @ConstructorProperties({\"years\",             \"ultimateAnswer\"})\n                    public   ExampleBean(int       years,    String    ultimateAnswer)       {\n                         this.years     =  years;\n                         this.ultimateAnswer         =  ultimateAnswer;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              package    examples\n\n\n              class    ExampleBean\n              @ConstructorProperties(\"years\",             \"ultimateAnswer\")\n              constructor(val       years:    Int,   val  ultimateAnswer:       String)\n\n\n\n\n            Setter-based  Dependency     Injection\n\n            Setter-based DI is accomplished by the container calling setter methods on your beans after\n            invoking a no-argument constructor or a no-argument static factory method to instantiate your\n            bean.\n\n            The following example shows a class that can only be dependency-injected by using pure setter\n            injection.  This  class  is  conventional   Java.  It is  a  POJO that has  no  dependencies      on  container    specific\n            interfaces,  base   classes,  or annotations.\n\n            Java\n\n\n              public    class   SimpleMovieLister        {\n\n\n                    //  the  SimpleMovieLister        has   a dependency      on  the  MovieFinder\n                    private    MovieFinder     movieFinder;\n\n\n                    //  a  setter   method    so  that   the  Spring    container     can  inject    a  MovieFinder\n                    public   void   setMovieFinder(MovieFinder           movieFinder)      {\n                         this.movieFinder        = movieFinder;\n                    }\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            Kotlin\n\n\n              class    SimpleMovieLister       {\n\n\n                    //  a  late-initialized       property    so   that  the   Spring    container    can   inject   a\n              MovieFinder\n                    lateinit    var   movieFinder:      MovieFinder\n\n\n                    //  business    logic    that  actually     uses   the  injected     MovieFinder     is  omitted...\n              }\n\n\n\n            The  ApplicationContext      supports    constructor-based       and  setter-based    DI  for the  beans   it manages.    It\n            also supports setter-based DI after some dependencies have already been injected through the\n            constructor    approach.    You   configure    the  dependencies      in the  form   of  a BeanDefinition,     which    you\n            use  in conjunction     with  PropertyEditor     instances    to convert   properties    from   one  format   to  another.\n            However,    most   Spring   users   do  not  work   with   these  classes  directly   (that is, programmatically)       but\n            rather  with   XML   bean  definitions,   annotated    components      (that  is,  classes annotated    with  @Component,\n            @Controller,   and   so forth),  or @Bean   methods    in  Java-based    @Configuration     classes.  These   sources   are\n            then converted internally into instances of BeanDefinition and used to load an entire Spring IoC\n            container   instance.\n\n                                           Constructor-based              or  setter-based          DI?\n\n               Since   you   can  mix   constructor-based       and  setter-based     DI, it is a  good   rule  of thumb     to use\n               constructors     for  mandatory      dependencies      and  setter   methods    or  configuration     methods     for\n               optional    dependencies.     Note   that  use  of  the  @Autowired      annotation     on  a setter   method    can\n               be  used   to make   the  property    be  a required    dependency;     however,     constructor    injection   with\n               programmatic       validation   of arguments      is  preferable.\n\n               The    Spring    team    generally     advocates     constructor     injection,    as  it  lets  you    implement\n               application components as immutable objects and ensures that required dependencies are\n               not null. Furthermore, constructor-injected components are always returned to the client\n               (calling) code in a fully initialized state. As a side note, a large number of constructor\n               arguments     is a bad   code  smell,  implying    that  the class  likely  has  too many    responsibilities    and\n               should   be  refactored    to better  address    proper   separation    of concerns.\n\n\n               Setter  injection   should   primarily    only  be  used   for optional   dependencies      that  can  be  assigned\n               reasonable default values within the class. Otherwise, not-null checks must be performed\n               everywhere the code uses the dependency. One benefit of setter injection is that setter\n               methods make objects of that class amenable to reconfiguration or re-injection later.\n               Management       through    JMX   MBeans     is  therefore  a compelling    use  case  for  setter  injection.\n\n\n               Use   the  DI  style that  makes     the  most   sense   for a  particular   class.  Sometimes,     when    dealing\n               with   third-party   classes   for which   you   do  not  have  the  source,   the  choice  is made    for you.  For\n               example,    if a third-party    class  does  not  expose   any   setter  methods,    then  constructor     injection\n               may   be  the  only  available   form   of DI.\n\n\n\n\n\n            Dependency    Resolution   Process\n\n            The  container    performs    bean   dependency      resolution   as  follows:\n\n\n              • The   ApplicationContext      is created   and   initialized  with  configuration     metadata     that  describes   all\n                the  beans.  Configuration     metadata     can  be  specified   by XML,   Java   code,  or annotations.\n\n              • For  each  bean,   its dependencies      are expressed     in the  form  of  properties,   constructor    arguments,\n                or arguments to the static-factory method (if you use that instead of a normal constructor).\n                These   dependencies      are  provided    to the bean,   when    the bean   is actually   created.\n\n              • Each   property    or constructor    argument     is an  actual   definition   of the  value  to  set,  or  a reference\n                to another    bean   in the  container.\n\n              • Each   property    or constructor     argument     that  is  a  value  is  converted  from   its  specified format    to\n                the  actual  type  of  that property    or  constructor    argument.     By default,   Spring   can  convert   a value\n                supplied   in  string  format   to all built-in  types,  such  as int,  long, String,   boolean,  and   so forth.\n\n            The  Spring   container    validates   the configuration     of each   bean   as the  container    is  created. However,\n            the bean properties themselves are not set until the bean is actually created. Beans that are\n            singleton-scoped and set to be pre-instantiated (the default) are created when the container is\n            created. Scopes are defined in Bean Scopes. Otherwise, the bean is created only when it is\n            requested. Creation of a bean potentially causes a graph of beans to be created, as the bean’s\n            dependencies      and  its dependencies'      dependencies      (and  so  on)  are  created   and   assigned.    Note  that\n\n            resolution   mismatches      among     those  dependencies      may    show   up  late — that    is,  on  first  creation of\n            the affected   bean.\n\n\n                                                       Circular       dependencies\n\n               If you use predominantly constructor injection, it is possible to create an unresolvable\n               circular   dependency      scenario.\n\n\n               For  example:    Class  A  requires   an  instance   of class  B through    constructor    injection,   and  class  B\n               requires an instance of class A through constructor injection. If you configure beans for\n               classes   A  and  B  to be  injected   into  each   other,  the  Spring   IoC  container    detects   this  circular\n               reference    at runtime,    and  throws    a BeanCurrentlyInCreationException.\n\n\n               One   possible    solution   is to edit  the  source   code   of  some   classes   to be   configured    by  setters\n               rather than constructors. Alternatively, avoid constructor injection and use setter injection\n               only.   In   other    words,    although     it  is  not    recommended,        you    can    configure     circular\n               dependencies      with  setter  injection.\n\n\n               Unlike   the  typical  case  (with   no  circular  dependencies),      a circular   dependency      between    bean\n               A and bean B forces one of the beans to be injected into the other prior to being fully\n               initialized   itself  (a  classic  chicken-and-egg   scenario).\n\n\n\n            You can generally trust Spring to do the right thing. It detects configuration problems, such as\n            references to non-existent beans and circular dependencies, at container load-time. Spring sets\n            properties    and  resolves    dependencies      as late  as  possible,   when    the  bean   is actually   created.   This\n            means    that a  Spring   container    that  has  loaded   correctly   can  later  generate    an  exception    when    you\n            request an object if there is a problem creating that object or one of its dependencies — for\n            example,    the bean   throws    an  exception    as a  result  of a missing   or  invalid   property.   This  potentially\n            delayed visibility of some configuration issues is why ApplicationContext implementations by\n            default pre-instantiate singleton beans. At the cost of some upfront time and memory to create\n            these   beans    before    they    are   actually   needed,     you    discover    configuration      issues   when     the\n            ApplicationContext      is created,  not  later. You   can  still  override  this default   behavior    so that  singleton\n            beans   initialize lazily, rather   than  being   eagerly   pre-instantiated.\n\n\n            If  no circular  dependencies      exist,  when    one  or  more   collaborating     beans   are  being   injected   into  a\n            dependent bean, each collaborating bean is totally configured prior to being injected into the\n            dependent     bean.  This   means    that, if bean   A  has  a dependency      on  bean   B, the  Spring   IoC  container\n            completely    configures    bean    B prior   to invoking    the  setter  method     on  bean   A. In  other   words,   the\n            bean is instantiated (if it is not a pre-instantiated singleton), its dependencies are set, and the\n            relevant lifecycle methods (such as a configured init method or the InitializingBean callback\n            method)    are  invoked.\n\n\n\n            Examples   of Dependency     Injection\n\n            The  following    example    uses  XML-based      configuration     metadata     for setter-based    DI. A  small   part  of\n            a Spring   XML   configuration     file specifies  some   bean   definitions   as  follows:\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <!--   setter   injection     using   the   nested   ref   element    -->\n                    <property     name=\"beanOne\">\n                         <ref   bean=\"anotherExampleBean\"/>\n                    </property>\n\n\n                    <!--   setter   injection     using   the   neater   ref   attribute     -->\n                    <property     name=\"beanTwo\"      ref=\"yetAnotherBean\"/>\n                    <property     name=\"integerProperty\"         value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    private    AnotherBean     beanOne;\n\n\n                    private    YetAnotherBean      beanTwo;\n\n\n                    private    int  i;\n\n\n                    public   void   setBeanOne(AnotherBean          beanOne)    {\n                         this.beanOne      =  beanOne;\n                    }\n\n\n                    public   void   setBeanTwo(YetAnotherBean           beanTwo)    {\n                         this.beanTwo      =  beanTwo;\n                    }\n\n\n                    public   void   setIntegerProperty(int          i)  {\n                         this.i    =  i;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     {\n                    lateinit    var   beanOne:    AnotherBean\n                    lateinit    var   beanTwo:    YetAnotherBean\n                    var  i:  Int   =  0\n              }\n\n\n\n            In the  preceding    example,    setters  are  declared    to match   against   the  properties    specified  in  the XML\n\n            file.  The  following  example    uses  constructor-based       DI:\n\n\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\">\n                    <!--   constructor     injection     using   the   nested   ref   element    -->\n                    <constructor-arg>\n                         <ref   bean=\"anotherExampleBean\"/>\n                    </constructor-arg>\n\n\n                    <!--   constructor     injection     using   the   neater   ref   attribute     -->\n                    <constructor-arg       ref=\"yetAnotherBean\"/>\n\n\n                    <constructor-arg       type=\"int\"     value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    private    AnotherBean     beanOne;\n\n\n                    private    YetAnotherBean      beanTwo;\n\n\n                    private    int  i;\n\n\n                    public   ExampleBean(\n                         AnotherBean      anotherBean,      YetAnotherBean      yetAnotherBean,       int   i)  {\n                         this.beanOne      =  anotherBean;\n                         this.beanTwo      =  yetAnotherBean;\n                         this.i    =  i;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean(\n                         private    val   beanOne:    AnotherBean,\n                         private    val   beanTwo:    YetAnotherBean,\n                         private    val   i:  Int)\n\n\n\n            The constructor arguments specified in the bean definition are used as arguments to the\n            constructor    of the  ExampleBean.\n\n\n            Now   consider    a variant   of this  example,    where,   instead   of using   a constructor,    Spring   is told  to call\n            a static  factory   method    to return   an  instance   of the  object:\n\n              <bean    id=\"exampleBean\"       class=\"examples.ExampleBean\"            factory-method=\"createInstance\">\n                    <constructor-arg       ref=\"anotherExampleBean\"/>\n                    <constructor-arg       ref=\"yetAnotherBean\"/>\n                    <constructor-arg       value=\"1\"/>\n              </bean>\n\n\n              <bean    id=\"anotherExampleBean\"          class=\"examples.AnotherBean\"/>\n              <bean    id=\"yetAnotherBean\"        class=\"examples.YetAnotherBean\"/>\n\n\n\n            The  following   example     shows   the  corresponding      ExampleBean    class:\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    //  a  private    constructor\n                    private    ExampleBean(...)       {\n                         ...\n                    }\n\n\n                    //  a  static   factory    method;    the   arguments     to  this   method   can   be\n                    //  considered     the   dependencies     of   the  bean   that   is  returned,\n                    //  regardless     of  how   those   arguments     are  actually     used.\n                    public   static    ExampleBean      createInstance      (\n                         AnotherBean      anotherBean,      YetAnotherBean      yetAnotherBean,       int   i)  {\n\n\n                         ExampleBean      eb  =  new  ExampleBean      (...);\n                         //  some   other    operations...\n                         return    eb;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     private    constructor()      {\n                    companion     object   {\n                         //  a  static    factory    method;    the  arguments     to  this   method    can  be\n                         //  considered      the  dependencies      of  the   bean  that   is  returned,\n                         //  regardless      of  how  those   arguments     are   actually    used.\n                         @JvmStatic\n                         fun   createInstance(anotherBean:           AnotherBean,      yetAnotherBean:       YetAnotherBean,\n              i:  Int):    ExampleBean     {\n                               val  eb  =  ExampleBean      (...)\n                               //  some   other   operations...\n                               return   eb\n                         }\n                    }\n              }\n\n            Arguments     to  the  static   factory  method     are  supplied    by  <constructor-arg/>      elements,    exactly   the\n            same   as if a constructor    had   actually   been  used.   The  type  of  the class  being   returned    by  the factory\n            method    does   not  have   to be  of  the same    type  as  the  class  that  contains   the  static   factory   method\n            (although, in this example, it is). An instance (non-static) factory method can be used in an\n            essentially   identical   fashion   (aside  from    the  use  of the  factory-bean     attribute   instead   of  the  class\n            attribute),  so we   do not  discuss   those  details  here.\n\n\n            Dependencies       and  Configuration       in Detail\n\n            As mentioned      in the previous    section,  you   can  define  bean   properties    and  constructor    arguments      as\n            references    to other  managed      beans   (collaborators)    or  as values   defined    inline. Spring’s   XML-based\n            configuration     metadata    supports    sub-element      types  within   its <property/>     and   <constructor-arg/>\n            elements    for this purpose.\n\n\n\n            Straight Values  (Primitives,  Strings,  and  so on)\n\n            The  value   attribute   of the  <property/>     element    specifies   a property    or  constructor     argument     as  a\n            human-readable       string  representation.      Spring’s   conversion    service   is used   to convert    these  values\n            from   a String  to  the actual   type  of the  property    or argument.     The  following    example    shows    various\n            values  being   set:\n\n\n\n              <bean    id=\"myDataSource\"       class=\"org.apache.commons.dbcp.BasicDataSource\"                   destroy-\n              method=\"close\">\n                    <!--   results    in  a  setDriverClassName(String)           call   -->\n                    <property     name=\"driverClassName\"         value=\"com.mysql.jdbc.Driver\"/>\n                    <property     name=\"url\"     value=\"jdbc:mysql://localhost:3306/mydb\"/>\n                    <property     name=\"username\"       value=\"root\"/>\n                    <property     name=\"password\"       value=\"misterkaoli\"/>\n              </bean>\n\n\n\n            The  following   example     uses  the  p-namespace      for even   more   succinct   XML   configuration:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                    https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"myDataSource\"        class=\"org.apache.commons.dbcp.BasicDataSource\"\n                         destroy-method=\"close\"\n                         p:driverClassName=\"com.mysql.jdbc.Driver\"\n                         p:url=\"jdbc:mysql://localhost:3306/mydb\"\n                         p:username=\"root\"\n                         p:password=\"misterkaoli\"/>\n\n\n              </beans>\n\n\n\n            The  preceding    XML    is more   succinct.   However,     typos  are  discovered     at runtime    rather   than  design\n\n            time, unless you use an IDE (such as IntelliJ IDEA or the Spring Tools for Eclipse) that supports\n            automatic property completion when you create bean definitions. Such IDE assistance is highly\n            recommended.\n\n\n            You  can  also  configure   a  java.util.Properties      instance,   as  follows:\n\n\n\n              <bean    id=\"mappings\"\n                    class=\"org.springframework.context.support.PropertySourcesPlaceholderConfigurer\">\n\n\n                    <!--   typed   as  a  java.util.Properties         -->\n                    <property     name=\"properties\">\n                         <value>\n                               jdbc.driver.className=com.mysql.jdbc.Driver\n                               jdbc.url=jdbc:mysql://localhost:3306/mydb\n                         </value>\n                    </property>\n              </bean>\n\n\n\n            The Spring container converts the text inside the <value/> element into a java.util.Properties\n            instance   by  using  the  JavaBeans     PropertyEditor     mechanism.      This  is a  nice  shortcut,   and  is one  of  a\n            few  places   where    the  Spring   team   do  favor   the  use  of the  nested    <value/>   element    over   the  value\n            attribute  style.\n\n\n            The  idref  element\n\n            The  idref   element    is simply   an  error-proof    way   to  pass  the  id (a  string  value   -  not a reference)    of\n            another bean in the container to a <constructor-arg/> or <property/> element. The following\n            example    shows   how    to use  it:\n\n\n\n              <bean    id=\"theTargetBean\"        class=\"...\"/>\n\n\n              <bean    id=\"theClientBean\"        class=\"...\">\n                    <property     name=\"targetName\">\n                         <idref    bean=\"theTargetBean\"/>\n                    </property>\n              </bean>\n\n\n\n            The  preceding    bean   definition   snippet   is exactly  equivalent    (at runtime)    to the  following   snippet:\n\n\n\n              <bean    id=\"theTargetBean\"        class=\"...\"     />\n\n\n              <bean    id=\"client\"     class=\"...\">\n                    <property     name=\"targetName\"       value=\"theTargetBean\"/>\n              </bean>\n\n\n\n            The  first form   is preferable    to the  second,   because    using  the  idref   tag lets the  container    validate   at\n            deployment time that the referenced, named bean actually exists. In the second variation, no\n\n            validation   is performed      on  the  value   that is passed    to the  targetName    property    of  the  client  bean.\n            Typos are only discovered (with most likely fatal results) when the client bean is actually\n            instantiated.   If the  client  bean   is a  prototype    bean,  this  typo  and   the  resulting   exception    may   only\n            be discovered     long  after the  container    is  deployed.\n\n\n                              The  local   attribute   on  the  idref   element    is no  longer   supported     in the  4.0  beans\n                              XSD, since it does not provide value over a regular bean reference any more.\n                             Change    your  existing   idref   local   references    to idref   bean  when    upgrading     to the\n                              4.0 schema.\n\n\n            A common      place   (at least  in  versions   earlier   than   Spring   2.0)  where    the  <idref/>   element    brings\n            value is in the configuration of AOP interceptors in a ProxyFactoryBean bean definition. Using\n            <idref/> elements when you specify the interceptor names prevents you from misspelling an\n            interceptor   ID.\n\n\n\n            References   to Other  Beans  (Collaborators)\n\n            The  ref  element    is the  final element    inside   a <constructor-arg/>      or  <property/>    definition   element.\n            Here, you set the value of the specified property of a bean to be a reference to another bean (a\n            collaborator)    managed     by  the  container.    The  referenced     bean   is a  dependency      of the  bean   whose\n            property    is to be  set, and   it is initialized   on  demand     as  needed    before   the  property    is set. (If the\n            collaborator    is a singleton    bean,  it may   already    be  initialized  by  the  container.)    All references    are\n            ultimately   a reference    to another    object.  Scoping   and   validation   depend    on  whether    you   specify  the\n            ID or  name   of the  other   object  through    the bean  or  parent  attribute.\n\n\n            Specifying   the  target  bean   through    the  bean  attribute   of the  <ref/>  tag  is the most   general    form  and\n            allows  creation    of a reference    to any   bean   in the  same   container    or parent    container,   regardless    of\n            whether it is in the same XML file. The value of the bean attribute may be the same as the id\n            attribute   of the  target  bean   or  be  the  same   as  one   of the  values   in the  name   attribute   of the  target\n            bean.  The  following    example    shows    how   to use  a ref  element:\n\n\n\n              <ref   bean=\"someBean\"/>\n\n\n\n            Specifying    the  target  bean   through    the  parent   attribute   creates   a  reference    to a  bean   that  is in  a\n            parent container of the current container. The value of the parent attribute may be the same as\n            either  the id  attribute  of  the target  bean   or  one  of the  values   in the  name  attribute  of  the target  bean.\n            The target bean must be in a parent container of the current one. You should use this bean\n            reference variant mainly when you have a hierarchy of containers and you want to wrap an\n            existing  bean   in  a parent   container    with   a proxy    that  has  the  same   name    as  the  parent   bean.   The\n            following   pair  of listings  shows   how   to use  the  parent   attribute:\n\n\n\n              <!--   in  the   parent   context    -->\n              <bean    id=\"accountService\"        class=\"com.something.SimpleAccountService\">\n                    <!--   insert   dependencies      as  required     here   -->\n              </bean>\n\n              <!--   in  the   child   (descendant)      context    -->\n              <bean    id=\"accountService\"        <!--   bean   name   is  the  same   as  the   parent   bean   -->\n                    class=\"org.springframework.aop.framework.ProxyFactoryBean\">\n                    <property     name=\"target\">\n                         <ref   parent=\"accountService\"/>           <!--   notice   how   we  refer   to  the   parent    bean  -->\n                    </property>\n                    <!--   insert   other    configuration      and  dependencies      as  required     here   -->\n              </bean>\n\n\n\n\n                              The  local  attribute   on  the  ref element    is no  longer   supported    in the  4.0 beans    XSD,\n                             since it does not provide value over a regular bean reference any more. Change\n                              your  existing   ref  local  references    to ref  bean  when    upgrading     to the 4.0  schema.\n\n\n\n            Inner Beans\n\n            A <bean/>   element    inside   the  <property/>    or  <constructor-arg/>      elements    defines   an  inner   bean,   as\n            the following    example    shows:\n\n\n\n              <bean    id=\"outer\"     class=\"...\">\n                    <!--   instead    of  using   a  reference     to  a target    bean,   simply    define    the  target    bean\n              inline    -->\n                    <property     name=\"target\">\n                         <bean    class=\"com.example.Person\">           <!--   this   is  the  inner    bean   -->\n                               <property     name=\"name\"     value=\"Fiona      Apple\"/>\n                               <property     name=\"age\"     value=\"25\"/>\n                         </bean>\n                    </property>\n              </bean>\n\n\n\n            An  inner  bean   definition   does   not  require   a defined   ID  or name.    If specified,  the  container    does  not\n            use such a value as an identifier. The container also ignores the scope flag on creation, because\n            inner  beans   are  always   anonymous       and  are  always    created   with  the  outer  bean.   It  is  not  possible  to\n            access inner beans independently or to inject them into collaborating beans other than into the\n            enclosing   bean.\n\n\n            As a  corner   case,  it  is  possible  to  receive  destruction  callbacks    from   a custom    scope — for    example,\n            for a request-scoped      inner   bean   contained    within   a singleton    bean.  The   creation   of  the inner   bean\n            instance is tied to its containing bean, but destruction callbacks let it participate in the request\n            scope’s  lifecycle.  This  is  not  a common    scenario.   Inner   beans   typically  simply   share   their  containing\n            bean’s  scope.\n\n\n\n            Collections\n\n            The <list/>, <set/>, <map/>, and <props/> elements set the properties and arguments of the Java\n            Collection    types  List,  Set,  Map, and   Properties,    respectively.   The   following    example     shows   how    to\n            use them:\n\n              <bean    id=\"moreComplexObject\"         class=\"example.ComplexObject\">\n                    <!--   results    in  a  setAdminEmails(java.util.Properties)              call   -->\n                    <property     name=\"adminEmails\">\n                         <props>\n                               <prop   key=\"administrator\">administrator@example.org</prop>\n                               <prop   key=\"support\">support@example.org</prop>\n                               <prop   key=\"development\">development@example.org</prop>\n                         </props>\n                    </property>\n                    <!--   results    in  a  setSomeList(java.util.List)           call   -->\n                    <property     name=\"someList\">\n                         <list>\n                               <value>a    list   element    followed    by   a reference</value>\n                               <ref   bean=\"myDataSource\"        />\n                         </list>\n                    </property>\n                    <!--   results    in  a  setSomeMap(java.util.Map)          call   -->\n                    <property     name=\"someMap\">\n                         <map>\n                               <entry   key=\"an    entry\"    value=\"just      some  string\"/>\n                               <entry   key=\"a    ref\"   value-ref=\"myDataSource\"/>\n                         </map>\n                    </property>\n                    <!--   results    in  a  setSomeSet(java.util.Set)          call   -->\n                    <property     name=\"someSet\">\n                         <set>\n                               <value>just     some   string</value>\n                               <ref   bean=\"myDataSource\"        />\n                         </set>\n                    </property>\n              </bean>\n\n\n\n            The  value  of  a map   key  or  value,  or a set  value,  can  also  be any  of  the following    elements:\n\n\n\n              bean   |  ref  |  idref   |  list   |  set  |  map   | props    | value    | null\n\n\n\n            Collection    Merging\n\n            The Spring container also supports merging collections. An application developer can define a\n            parent   <list/>,  <map/>,  <set/>   or  <props/>   element    and  have   child  <list/>,  <map/>,   <set/>  or  <props/>\n            elements inherit and override values from the parent collection. That is, the child collection’s\n            values   are  the  result  of merging     the  elements    of the  parent    and  child   collections,   with  the  child’s\n            collection  elements    overriding    values   specified   in the  parent   collection.\n\n\n            This section on merging discusses the parent-child bean mechanism. Readers unfamiliar with\n            parent   and  child  bean   definitions   may   wish   to read  the  relevant   section   before  continuing.\n\n\n            The  following   example     demonstrates     collection   merging:\n\n              <beans>\n                    <bean   id=\"parent\"      abstract=\"true\"       class=\"example.ComplexObject\">\n                         <property     name=\"adminEmails\">\n                               <props>\n                                    <prop    key=\"administrator\">administrator@example.com</prop>\n                                    <prop    key=\"support\">support@example.com</prop>\n                               </props>\n                         </property>\n                    </bean>\n                    <bean   id=\"child\"     parent=\"parent\">\n                         <property     name=\"adminEmails\">\n                               <!--   the  merge   is   specified    on  the   child   collection     definition     -->\n                               <props   merge=\"true\">\n                                    <prop    key=\"sales\">sales@example.com</prop>\n                                    <prop    key=\"support\">support@example.co.uk</prop>\n                               </props>\n                         </property>\n                    </bean>\n              <beans>\n\n\n\n            Notice  the  use  of the  merge=true    attribute  on  the  <props/>   element    of the  adminEmails    property    of the\n            child bean definition. When the child bean is resolved and instantiated by the container, the\n            resulting   instance   has  an  adminEmails     Properties    collection   that  contains   the  result  of  merging    the\n            child’s  adminEmails    collection   with   the  parent’s   adminEmails    collection.   The   following    listing shows\n            the result:\n\n\n\n              administrator=administrator@example.com\n              sales=sales@example.com\n              support=support@example.co.uk\n\n\n\n            The  child  Properties    collection’s   value   set inherits   all property    elements    from   the  parent   <props/>,\n            and  the  child’s value   for the  support   value  overrides    the  value  in  the parent   collection.\n\n\n            This  merging    behavior     applies   similarly   to the  <list/>,   <map/>,   and  <set/>   collection   types.   In the\n            specific  case  of the  <list/>   element,    the  semantics    associated    with   the List   collection   type  (that  is,\n            the notion    of an  ordered   collection   of  values)  is maintained.     The   parent’s   values   precede    all of the\n            child list’s values. In the case of the Map, Set, and Properties collection types, no ordering exists.\n            Hence,   no  ordering    semantics    are  in effect  for  the collection   types   that  underlie   the  associated    Map,\n            Set, and  Properties    implementation       types  that  the container    uses  internally.\n\n\n            Limitations     of Collection    Merging\n\n            You  cannot   merge    different   collection  types   (such  as  a Map and   a List).  If  you do  attempt   to do  so, an\n            appropriate    Exception    is  thrown.  The  merge   attribute  must   be  specified   on  the lower,   inherited,   child\n            definition.  Specifying    the  merge  attribute   on a  parent   collection  definition    is  redundant   and   does  not\n            result in  the desired   merging.\n\n            Strongly-typed      collection\n\n            Thanks to Java’s support for generic types, you can use strongly typed collections. That is, it is\n            possible   to declare   a Collection    type  such   that  it  can  only contain   (for example)     String   elements.   If\n            you use Spring to dependency-inject a strongly-typed Collection into a bean, you can take\n            advantage of Spring’s type-conversion support such that the elements of your strongly-typed\n            Collection    instances   are  converted     to the  appropriate     type  prior  to  being   added   to  the Collection.\n            The  following   Java   class and   bean  definition   show    how   to do  so:\n\n\n            Java\n\n\n              public    class   SomeClass     {\n\n\n                    private    Map<String,     Float>    accounts;\n\n\n                    public   void   setAccounts(Map<String,          Float>    accounts)     {\n                         this.accounts       = accounts;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    SomeClass    {\n                    lateinit    var   accounts:    Map<String,      Float>\n              }\n\n\n\n\n              <beans>\n                    <bean   id=\"something\"       class=\"x.y.SomeClass\">\n                         <property     name=\"accounts\">\n                               <map>\n                                    <entry    key=\"one\"     value=\"9.99\"/>\n                                    <entry    key=\"two\"     value=\"2.75\"/>\n                                    <entry    key=\"six\"     value=\"3.99\"/>\n                               </map>\n                         </property>\n                    </bean>\n              </beans>\n\n\n\n            When     the   accounts    property     of  the   something     bean    is  prepared     for   injection,   the   generics\n            information about the element type of the strongly-typed Map<String, Float> is available by\n            reflection.  Thus,   Spring’s   type  conversion     infrastructure     recognizes    the  various    value  elements     as\n            being  of  type  Float,  and   the  string  values   (9.99,  2.75,  and  3.99)   are  converted    into  an  actual   Float\n            type.\n\n\n\n            Null and  Empty   String Values\n\n            Spring   treats  empty    arguments     for  properties    and   the  like  as empty    Strings.   The   following    XML-\n            based   configuration    metadata     snippet   sets the  email  property    to the empty    String   value  (\"\").\n\n              <bean    class=\"ExampleBean\">\n                    <property     name=\"email\"     value=\"\"/>\n              </bean>\n\n\n\n            The  preceding    example    is equivalent    to the  following    Java  code:\n\n\n            Java\n\n\n              exampleBean.setEmail(\"\");\n\n\n\n            Kotlin\n\n\n              exampleBean.email        =  \"\"\n\n\n\n            The  <null/>   element    handles   null  values.  The   following   listing  shows   an  example:\n\n\n\n              <bean    class=\"ExampleBean\">\n                    <property     name=\"email\">\n                         <null/>\n                    </property>\n              </bean>\n\n\n\n            The  preceding    configuration     is  equivalent   to the following    Java  code:\n\n\n            Java\n\n\n              exampleBean.setEmail(null);\n\n\n\n            Kotlin\n\n\n              exampleBean.email        =  null\n\n\n\n\n            XML  Shortcut   with  the p-namespace\n\n            The  p-namespace      lets you   use  the bean  element’s    attributes   (instead   of nested   <property/>    elements)\n            to describe   your   property   values   collaborating    beans,   or both.\n\n\n            Spring supports extensible configuration formats with namespaces, which are based on an XML\n            Schema    definition.   The   beans  configuration     format    discussed    in this  chapter   is defined    in an  XML\n            Schema    document.     However,     the  p-namespace       is not  defined   in  an  XSD   file and  exists  only   in the\n            core  of Spring.\n\n\n            The following example shows two XML snippets (the first uses standard XML format and the\n            second   uses  the  p-namespace)      that resolve   to the  same   result:\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   name=\"classic\"       class=\"com.example.ExampleBean\">\n                         <property     name=\"email\"      value=\"someone@somewhere.com\"/>\n                    </bean>\n\n\n                    <bean   name=\"p-namespace\"        class=\"com.example.ExampleBean\"\n                         p:email=\"someone@somewhere.com\"/>\n              </beans>\n\n\n\n            The  example     shows    an  attribute   in the  p-namespace       called  email  in  the  bean   definition.   This  tells\n            Spring   to include   a property    declaration.    As  previously    mentioned,     the p-namespace       does  not  have\n            a schema    definition,   so you  can  set  the name    of the  attribute   to the property    name.\n\n\n            This  next  example    includes   two   more   bean   definitions   that  both  have   a reference    to another   bean:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:p=\"http://www.springframework.org/schema/p\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   name=\"john-classic\"         class=\"com.example.Person\">\n                         <property     name=\"name\"      value=\"John     Doe\"/>\n                         <property     name=\"spouse\"      ref=\"jane\"/>\n                    </bean>\n\n\n                    <bean   name=\"john-modern\"\n                         class=\"com.example.Person\"\n                         p:name=\"John      Doe\"\n                         p:spouse-ref=\"jane\"/>\n\n\n                    <bean   name=\"jane\"      class=\"com.example.Person\">\n                         <property     name=\"name\"      value=\"Jane     Doe\"/>\n                    </bean>\n              </beans>\n\n\n\n            This example includes not only a property value using the p-namespace but also uses a special\n            format    to   declare    property     references.     Whereas       the   first  bean    definition     uses   <property\n            name=\"spouse\" ref=\"jane\"/> to create a reference from bean john to bean jane, the second bean\n            definition   uses  p:spouse-ref=\"jane\"       as an  attribute   to do  the exact   same   thing.  In this  case,  spouse  is\n            the property name, whereas the -ref part indicates that this is not a straight value but rather a\n            reference   to another    bean.\n\n                              The  p-namespace       is  not  as  flexible  as  the  standard  XML    format.   For  example,    the\n                              format   for  declaring    property    references    clashes   with   properties   that  end   in  Ref,\n                             whereas    the  standard    XML   format    does  not.  We   recommend       that  you  choose   your\n                              approach     carefully    and    communicate        this  to   your   team    members       to  avoid\n                              producing    XML    documents     that  use  all  three approaches     at the  same   time.\n\n\n\n            XML  Shortcut   with  the c-namespace\n\n            Similar to the XML Shortcut with the p-namespace, the c-namespace, introduced in Spring 3.1,\n            allows  inlined   attributes   for configuring     the constructor    arguments      rather  then   nested   constructor-\n            arg elements.\n\n\n            The  following    example    uses   the  c: namespace      to do  the  same    thing  as the  from   Constructor-based\n            Dependency      Injection:\n\n\n\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:c=\"http://www.springframework.org/schema/c\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\">\n\n\n                    <bean   id=\"beanTwo\"      class=\"x.y.ThingTwo\"/>\n                    <bean   id=\"beanThree\"       class=\"x.y.ThingThree\"/>\n\n\n                    <!--   traditional     declaration      with   optional    argument    names    -->\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\">\n                         <constructor-arg        name=\"thingTwo\"       ref=\"beanTwo\"/>\n                         <constructor-arg        name=\"thingThree\"       ref=\"beanThree\"/>\n                         <constructor-arg        name=\"email\"      value=\"something@somewhere.com\"/>\n                    </bean>\n\n\n                    <!--   c-namespace     declaration      with   argument    names   -->\n                    <bean   id=\"beanOne\"      class=\"x.y.ThingOne\"         c:thingTwo-ref=\"beanTwo\"\n                         c:thingThree-ref=\"beanThree\"            c:email=\"something@somewhere.com\"/>\n\n\n              </beans>\n\n\n\n            The  c: namespace      uses   the same    conventions     as the  p: one   (a trailing  -ref  for  bean   references)    for\n            setting  the  constructor    arguments     by  their  names.   Similarly,   it needs   to be  declared   in  the  XML   file\n            even  though    it  is  not  defined  in  an  XSD  schema  (it  exists  inside  the  Spring core).\n\n            For the  rare  cases   where   the  constructor    argument     names    are  not  available   (usually   if  the  bytecode\n            was   compiled    without    debugging     information),     you   can  use  fallback   to  the  argument     indexes,    as\n            follows:\n\n              <!--   c-namespace      index   declaration     -->\n              <bean    id=\"beanOne\"     class=\"x.y.ThingOne\"         c:_0-ref=\"beanTwo\"        c:_1-ref=\"beanThree\"\n                    c:_2=\"something@somewhere.com\"/>\n\n\n\n\n                              Due  to  the XML    grammar,     the  index   notation    requires   the  presence    of the  leading\n                              _, as XML attribute names cannot start with a number (even though some IDEs\n                             allow it). A corresponding index notation is also available for <constructor-arg>\n                              elements but not commonly used since the plain order of declaration is usually\n                              sufficient  there.\n\n\n            In practice, the constructor resolution mechanism is quite efficient in matching arguments, so\n            unless  you   really need   to, we  recommend       using   the name    notation   throughout     your   configuration.\n\n\n\n            Compound     Property  Names\n\n            You can use compound or nested property names when you set bean properties, as long as all\n            components      of the  path   except   the  final property    name    are  not   null. Consider    the  following    bean\n            definition:\n\n\n\n              <bean    id=\"something\"      class=\"things.ThingOne\">\n                    <property     name=\"fred.bob.sammy\"         value=\"123\"     />\n              </bean>\n\n\n\n            The  something    bean   has  a fred  property,    which   has  a  bob property,    which   has  a  sammy  property,   and\n            that final  sammy  property    is being  set  to a value   of 123. In  order  for  this to work,   the  fred  property    of\n            something   and   the  bob property    of  fred  must   not  be  null  after  the bean   is constructed.    Otherwise,     a\n            NullPointerException      is thrown.\n\n\n            Using   depends-on\n\n            If  a  bean is  a  dependency    of another    bean,  that  usually   means    that  one  bean   is set as  a property    of\n            another. Typically you accomplish this with the <ref/> element in XML-based configuration\n            metadata.    However,     sometimes     dependencies      between    beans   are  less  direct. An   example    is when    a\n            static initializer in a class needs to be triggered, such as for database driver registration. The\n            depends-on    attribute   can  explicitly  force   one  or  more   beans    to be  initialized  before   the  bean   using\n            this element is initialized. The following example uses the depends-on attribute to express a\n            dependency     on  a single   bean:\n\n\n\n              <bean    id=\"beanOne\"     class=\"ExampleBean\"         depends-on=\"manager\"/>\n              <bean    id=\"manager\"     class=\"ManagerBean\"         />\n\n\n\n            To express    a dependency      on  multiple   beans,   supply   a list  of  bean  names  as  the value   of the  depends-\n            on attribute   (commas,    whitespace,     and  semicolons     are valid  delimiters):\n\n              <bean    id=\"beanOne\"     class=\"ExampleBean\"         depends-on=\"manager,accountDao\">\n                    <property     name=\"manager\"      ref=\"manager\"      />\n              </bean>\n\n\n              <bean    id=\"manager\"     class=\"ManagerBean\"         />\n              <bean    id=\"accountDao\"       class=\"x.y.jdbc.JdbcAccountDao\"             />\n\n\n\n\n                              The  depends-on    attribute  can   specify  both   an initialization-time     dependency      and,  in\n                              the case of singleton beans only, a corresponding destruction-time dependency.\n                             Dependent beans that define a depends-on relationship with a given bean are\n                              destroyed    first,  prior  to  the  given  bean itself being   destroyed.   Thus,   depends-on    can\n                              also control   shutdown     order.\n\n\n\n            Lazy-initialized     Beans\n\n            By  default,  ApplicationContext      implementations       eagerly   create   and  configure    all singleton   beans    as\n            part  of the  initialization  process.   Generally,    this pre-instantiation     is desirable,   because   errors   in the\n            configuration or surrounding environment are discovered immediately, as opposed to hours or\n            even days later. When this behavior is not desirable, you can prevent pre-instantiation of a\n            singleton   bean   by  marking    the  bean   definition   as being   lazy-initialized.   A  lazy-initialized   bean   tells\n            the IoC  container    to create  a bean   instance   when    it is  first  requested, rather   than  at startup.\n\n\n            In XML, this behavior is controlled by the lazy-init attribute on the <bean/> element, as the\n            following   example    shows:\n\n\n\n              <bean    id=\"lazy\"    class=\"com.something.ExpensiveToCreateBean\"                  lazy-init=\"true\"/>\n              <bean    name=\"not.lazy\"       class=\"com.something.AnotherBean\"/>\n\n\n\n            When the preceding configuration is consumed by an ApplicationContext, the lazy bean is not\n            eagerly   pre-instantiated     when    the  ApplicationContext      starts,  whereas    the  not.lazy    bean   is eagerly\n            pre-instantiated.\n\n\n            However, when a lazy-initialized bean is a dependency of a singleton bean that is not lazy-\n            initialized, the ApplicationContext creates the lazy-initialized bean at startup, because it must\n            satisfy the singleton’s dependencies. The lazy-initialized bean is injected into a singleton bean\n            elsewhere    that  is  not  lazy-initialized.\n\n            You can also control lazy-initialization at the container level by using the default-lazy-init\n            attribute  on  the  <beans/>   element,   as  the following    example    shows:\n\n\n\n              <beans    default-lazy-init=\"true\">\n                    <!--   no  beans   will   be  pre-instantiated...         -->\n              </beans>\n\n            Autowiring     Collaborators\n\n            The  Spring   container    can   autowire    relationships     between    collaborating     beans.   You  can   let Spring\n            resolve   collaborators    (other   beans)   automatically     for  your   bean   by  inspecting    the  contents    of the\n            ApplicationContext.      Autowiring    has  the  following    advantages:\n\n              • Autowiring can significantly reduce the need to specify properties or constructor arguments.\n                (Other mechanisms such as a bean template discussed elsewhere in this chapter are also\n                valuable    in this regard.)\n\n              • Autowiring     can  update    a configuration    as  your  objects   evolve.  For  example,    if you  need   to add   a\n                dependency      to  a class,  that dependency       can  be  satisfied  automatically     without    you   needing    to\n                modify the configuration. Thus autowiring can be especially useful during development,\n                without    negating    the option   of  switching    to explicit  wiring    when    the code   base   becomes     more\n                stable.\n\n\n            When using XML-based configuration metadata (see Dependency Injection), you can specify the\n            autowire mode for a bean definition with the autowire attribute of the <bean/> element. The\n            autowiring functionality has four modes. You specify autowiring per bean and can thus choose\n            which   ones  to  autowire.   The   following   table  describes   the  four  autowiring     modes:\n\n\n            Table 2. Autowiring    modes\n\n            Mode                     Explanation\n            no                       (Default)   No  autowiring.    Bean   references    must   be  defined   by  ref elements.\n                                     Changing     the default   setting  is not  recommended       for  larger  deployments,\n                                     because    specifying   collaborators     explicitly  gives  greater   control  and   clarity. To\n                                     some    extent,  it  documents    the structure   of  a system.\n            byName                   Autowiring     by  property    name.   Spring   looks  for a  bean  with   the same    name   as\n                                     the  property    that needs   to be  autowired.    For  example,    if a bean   definition   is\n                                     set to  autowire    by name    and  it contains   a master   property    (that is, it  has  a\n                                     setMaster(..)     method),    Spring   looks  for a  bean  definition   named     master  and\n                                     uses  it to set the  property.\n            byType                   Lets  a property    be  autowired    if exactly  one   bean  of  the property    type  exists  in\n                                     the  container.   If more   than   one  exists, a  fatal exception    is  thrown,  which\n                                     indicates   that  you  may   not  use  byType   autowiring    for that  bean.   If  there are no\n                                     matching     beans,  nothing    happens    (the  property   is not  set).\n            constructor              Analogous     to byType   but  applies  to constructor    arguments.     If there  is not\n                                     exactly   one  bean   of the  constructor    argument     type  in the  container,   a fatal\n                                     error   is  raised.\n\n\n            With byType or constructor autowiring mode, you can wire arrays and typed collections. In such\n            cases,  all autowire    candidates     within   the  container    that  match    the  expected    type  are  provided     to\n            satisfy  the  dependency.     You   can  autowire     strongly-typed     Map  instances   if the  expected    key   type  is\n            String. An autowired Map instance’s values consist of all bean instances that match the expected\n            type, and   the Map  instance’s   keys  contain   the  corresponding      bean   names.\n\n            Limitations  and  Disadvantages    of Autowiring\n\n            Autowiring works best when it is used consistently across a project. If autowiring is not used in\n            general,  it might   be confusing    to developers     to use  it  to  wire  only  one  or  two  bean definitions.\n\n\n            Consider   the  limitations   and   disadvantages     of autowiring:\n\n              • Explicit  dependencies      in  property   and  constructor-arg      settings  always    override   autowiring.     You\n                cannot    autowire    simple   properties    such  as  primitives,   Strings,   and   Classes   (and  arrays   of such\n                simple   properties).   This  limitation   is by-design.\n\n              • Autowiring     is less  exact  than   explicit  wiring.   Although,    as  noted   in  the  earlier  table,  Spring   is\n                careful to avoid guessing in case of ambiguity that might have unexpected results. The\n                relationships    between    your   Spring-managed       objects   are  no longer   documented      explicitly.\n\n              • Wiring information may not be available to tools that may generate documentation from a\n                Spring   container.\n\n              • Multiple bean definitions within the container may match the type specified by the setter\n                method    or  constructor    argument     to be  autowired.    For  arrays,  collections,   or Map  instances,   this is\n                not  necessarily    a problem.    However,     for dependencies      that  expect   a single  value,  this  ambiguity\n                is not  arbitrarily  resolved.   If no  unique   bean   definition   is available,   an  exception   is thrown.\n\n\n            In the  latter scenario,   you  have   several   options:\n\n              • Abandon     autowiring     in favor  of explicit  wiring.\n\n              • Avoid   autowiring     for  a bean   definition    by  setting  its autowire-candidate       attributes   to false,   as\n                described    in the  next  section.\n\n              • Designate    a single  bean   definition   as the  primary    candidate    by  setting  the  primary  attribute   of its\n                <bean/>   element    to true.\n\n              • Implement the more fine-grained control available with annotation-based configuration, as\n                described    in Annotation-based       Container    Configuration.\n\n\n\n            Excluding   a  Bean from  Autowiring\n\n            On a per-bean basis, you can exclude a bean from autowiring. In Spring’s XML format, set the\n            autowire-candidate      attribute   of the  <bean/>  element    to false.  The   container    makes   that  specific  bean\n            definition   unavailable     to the  autowiring     infrastructure     (including   annotation     style  configurations\n            such  as @Autowired).\n\n\n                              The  autowire-candidate       attribute   is designed    to only  affect  type-based     autowiring.\n                              It does not affect explicit references by name, which get resolved even if the\n                             specified bean is not marked as an autowire candidate. As a consequence,\n                              autowiring    by  name    nevertheless    injects  a bean   if  the  name  matches.\n\n\n            You can also limit autowire candidates based on pattern-matching against bean names. The top-\n            level <beans/> element accepts one or more patterns within its default-autowire-candidates\n            attribute. For example, to limit autowire candidate status to any bean whose name ends with\n            Repository,   provide    a value   of *Repository.    To  provide    multiple   patterns,   define   them   in  a comma-\n            separated    list.  An  explicit  value of true  or  false  for  a bean   definition’s   autowire-candidate      attribute\n\n            always   takes  precedence.     For  such  beans,   the pattern   matching     rules  do  not apply.\n\n\n            These techniques are useful for beans that you never want to be injected into other beans by\n            autowiring. It does not mean that an excluded bean cannot itself be configured by using\n            autowiring.    Rather,   the bean   itself is not a  candidate    for autowiring    other   beans.\n\n\n            Method    Injection\n\n            In most   application    scenarios,    most   beans   in the  container    are   singletons.   When    a  singleton   bean\n            needs   to collaborate    with  another    singleton   bean   or a  non-singleton     bean   needs   to collaborate    with\n            another non-singleton bean, you typically handle the dependency by defining one bean as a\n            property    of the  other.  A  problem     arises  when    the  bean   lifecycles   are  different.  Suppose     singleton\n            bean   A  needs   to use   non-singleton     (prototype)    bean   B, perhaps     on  each   method    invocation     on  A.\n            The  container    creates   the singleton    bean   A only  once,   and  thus   only  gets  one  opportunity     to set the\n            properties.   The   container    cannot   provide    bean   A  with  a  new   instance   of  bean   B every   time   one  is\n            needed.\n\n            A solution   is to  forego   some   inversion    of control.   You  can   make   bean   A  aware    of the  container    by\n            implementing the ApplicationContextAware interface, and by making a getBean(\"B\") call to the\n            container ask for (a typically new) bean B instance every time bean A needs it. The following\n            example    shows   this  approach:\n\n            Java\n\n\n              //  a  class   that   uses   a  stateful    Command-style       class   to  perform    some   processing\n              package    fiona.apple;\n\n\n              //  Spring-API      imports\n              import    org.springframework.beans.BeansException;\n              import    org.springframework.context.ApplicationContext;\n              import    org.springframework.context.ApplicationContextAware;\n\n\n              public    class   CommandManager       implements     ApplicationContextAware          {\n\n\n                    private    ApplicationContext        applicationContext;\n\n\n                    public   Object    process(Map      commandState)      {\n                         //  grab   a  new   instance    of  the   appropriate     Command\n                         Command    command    =  createCommand();\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    protected     Command    createCommand()       {\n                         //  notice    the   Spring   API   dependency!\n                         return    this.applicationContext.getBean(\"command\",                 Command.class);\n                    }\n\n\n                    public   void   setApplicationContext(\n                               ApplicationContext        applicationContext)        throws    BeansException       {\n                         this.applicationContext          =  applicationContext;\n                    }\n              }\n\n            Kotlin\n\n\n              //  a  class   that   uses   a  stateful    Command-style       class   to  perform    some   processing\n              package    fiona.apple\n\n\n              //  Spring-API      imports\n              import    org.springframework.context.ApplicationContext\n              import    org.springframework.context.ApplicationContextAware\n\n\n              class    CommandManager      :  ApplicationContextAware          {\n\n\n                    private    lateinit    var   applicationContext:        ApplicationContext\n\n\n                    fun  process(commandState:          Map<*,   *>):   Any   {\n                         //  grab   a  new   instance    of  the   appropriate     Command\n                         val   command    =  createCommand()\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    //  notice    the  Spring    API  dependency!\n                    protected     fun  createCommand()       =\n                               applicationContext.getBean(\"command\",               Command::class.java)\n\n\n                    override    fun   setApplicationContext(applicationContext:                ApplicationContext)         {\n                         this.applicationContext          =  applicationContext\n                    }\n              }\n\n\n\n            The preceding is not desirable, because the business code is aware of and coupled to the Spring\n            Framework.      Method    Injection,   a somewhat      advanced     feature   of  the  Spring   IoC  container,   lets  you\n            handle   this use  case  cleanly.\n\n\n\n               You   can  read  more   about   the  motivation    for  Method    Injection   in this blog  entry.\n\n\n\n\n\n            Lookup   Method   Injection\n\n            Lookup    method    injection   is the  ability of  the  container   to  override   methods     on  container-managed\n            beans   and  return   the  lookup    result  for another    named     bean   in the  container.    The  lookup    typically\n            involves a prototype bean, as in the scenario described in the preceding section. The Spring\n            Framework      implements     this  method    injection   by  using  bytecode    generation    from   the  CGLIB    library\n            to dynamically     generate   a  subclass   that overrides    the  method.\n\n                                • For  this  dynamic    subclassing    to  work,   the  class that  the  Spring   bean   container\n                                  subclasses    cannot   be  final,  and   the  method    to  be  overridden     cannot   be  final,\n                                  either.\n\n                                • Unit-testing    a class  that  has   an  abstract   method     requires    you  to  subclass   the\n                                  class  yourself   and  to supply   a stub  implementation       of the  abstract   method.\n                               • Concrete    methods     are  also necessary     for component      scanning,    which    requires\n                                  concrete   classes   to pick  up.\n\n                                • A further key limitation is that lookup methods do not work with factory\n                                  methods and in particular not with @Bean methods in configuration classes,\n                                  since,  in  that  case, the  container    is not  in  charge   of  creating   the  instance   and\n                                  therefore   cannot    create  a runtime-generated        subclass   on  the fly.\n\n\n            In the case of the CommandManager class in the previous code snippet, the Spring container\n            dynamically     overrides    the implementation       of the  createCommand()      method.    The  CommandManager     class\n            does  not  have   any  Spring   dependencies,     as the  reworked     example    shows:\n\n\n            Java\n\n\n              package    fiona.apple;\n\n\n              //  no   more  Spring    imports!\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         //  grab   a  new   instance    of  the   appropriate     Command    interface\n                         Command    command    =  createCommand();\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    //  okay...    but  where    is  the  implementation       of  this   method?\n                    protected     abstract    Command    createCommand();\n              }\n\n            Kotlin\n\n\n              package    fiona.apple\n\n\n              //  no   more  Spring    imports!\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         //  grab   a  new   instance    of  the   appropriate     Command    interface\n                         val   command    =  createCommand()\n                         //  set   the  state    on  the  (hopefully     brand    new)   Command    instance\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    //  okay...    but  where    is  the  implementation       of  this   method?\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            In the client class that contains the method to be injected (the CommandManager in this case), the\n            method    to be  injected  requires    a signature   of the  following    form:\n\n\n\n              <public|protected>        [abstract]      <return-type>      theMethodName(no-arguments);\n\n\n\n            If  the  method   is abstract,   the  dynamically-generated         subclass   implements      the  method.    Otherwise,\n            the dynamically-generated subclass overrides the concrete method defined in the original class.\n            Consider   the  following    example:\n\n\n\n              <!--   a  stateful    bean   deployed     as  a prototype     (non-singleton)       -->\n              <bean    id=\"myCommand\"      class=\"fiona.apple.AsyncCommand\"              scope=\"prototype\">\n                    <!--   inject   dependencies      here   as  required     -->\n              </bean>\n\n\n              <!--   commandProcessor        uses  statefulCommandHelper          -->\n              <bean    id=\"commandManager\"        class=\"fiona.apple.CommandManager\">\n                    <lookup-method      name=\"createCommand\"         bean=\"myCommand\"/>\n              </bean>\n\n\n\n            The bean identified as commandManager calls its own createCommand() method whenever it needs a\n            new   instance   of the  myCommand   bean.   You  must   be  careful  to deploy   the  myCommand    bean   as a prototype\n            if that is actually what is needed. If it is a singleton, the same instance of the myCommand bean is\n            returned   each   time.\n\n\n            Alternatively, within the annotation-based component model, you can declare a lookup method\n            through   the  @Lookup   annotation,    as the  following   example     shows:\n\n            Java\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         Command    command    =  createCommand();\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    @Lookup(\"myCommand\")\n                    protected     abstract    Command    createCommand();\n              }\n\n\n\n            Kotlin\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         val   command    =  createCommand()\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    @Lookup(\"myCommand\")\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            Or, more    idiomatically,   you   can  rely on  the  target  bean   getting   resolved   against   the  declared   return\n            type  of the lookup    method:\n\n\n            Java\n\n\n              public    abstract    class    CommandManager      {\n\n\n                    public   Object    process(Object       commandState)      {\n                         Command    command    =  createCommand();\n                         command.setState(commandState);\n                         return    command.execute();\n                    }\n\n\n                    @Lookup\n                    protected     abstract    Command    createCommand();\n              }\n\n            Kotlin\n\n\n              abstract     class   CommandManager       {\n\n\n                    fun  process(commandState:          Any):   Any  {\n                         val   command    =  createCommand()\n                         command.state       = commandState\n                         return    command.execute()\n                    }\n\n\n                    @Lookup\n                    protected     abstract    fun  createCommand():        Command\n              }\n\n\n\n            Note that you should typically declare such annotated lookup methods with a concrete stub\n            implementation,      in order   for them    to be  compatible    with   Spring’s  component      scanning    rules  where\n            abstract classes get ignored by default. This limitation does not apply to explicitly registered or\n            explicitly  imported    bean   classes.\n\n\n                              Another way of accessing differently scoped target beans is an ObjectFactory/\n                              Provider   injection  point.  See  Scoped    Beans   as Dependencies.\n                 \n                              You       may        also      find       the       ServiceLocatorFactoryBean             (in      the\n                              org.springframework.beans.factory.config             package)    to be useful.\n\n\n\n            Arbitrary  Method   Replacement\n\n            A less useful form of method injection than lookup method injection is the ability to replace\n            arbitrary   methods     in a  managed     bean    with  another    method     implementation.       You  can   safely  skip\n            the rest  of this section   until you   actually  need   this functionality.\n\n\n            With XML-based configuration metadata, you can use the replaced-method element to replace an\n            existing  method     implementation       with   another,   for  a  deployed    bean.   Consider    the  following    class,\n            which   has  a method    called  computeValue     that  we  want   to override:\n\n\n            Java\n\n\n              public    class   MyValueCalculator        {\n\n\n                    public   String    computeValue(String         input)   {\n                         //  some   real   code...\n                    }\n\n\n                    //  some   other   methods...\n              }\n\n            Kotlin\n\n\n              class    MyValueCalculator       {\n\n\n                    fun  computeValue(input:         String):    String    {\n                         //  some   real   code...\n                    }\n\n\n                    //  some   other   methods...\n              }\n\n\n\n            A class that implements the org.springframework.beans.factory.support.MethodReplacer interface\n            provides   the  new   method    definition,   as the  following   example     shows:\n\n\n            Java\n\n\n              /**\n               *  meant    to  be  used   to  override    the   existing    computeValue(String)\n               *  implementation       in  MyValueCalculator\n               */\n              public    class   ReplacementComputeValue          implements     MethodReplacer       {\n\n\n                    public   Object    reimplement(Object        o,  Method    m,  Object[]    args)    throws   Throwable     {\n                         //  get   the  input    value,   work   with   it,   and  return    a computed     result\n                         String    input   =  (String)    args[0];\n                         ...\n                         return    ...;\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              /**\n               *  meant    to  be  used   to  override    the   existing    computeValue(String)\n               *  implementation       in  MyValueCalculator\n               */\n              class    ReplacementComputeValue          : MethodReplacer       {\n\n\n                    override    fun   reimplement(obj:       Any,   method:    Method,    args:   Array<out     Any>):    Any  {\n                         //  get   the  input    value,   work   with   it,   and  return    a computed     result\n                         val   input   =  args[0]    as  String;\n                         ...\n                         return    ...;\n                    }\n              }\n\n\n\n            The  bean   definition    to deploy   the  original   class  and   specify   the  method    override    would    resemble\n            the following    example:\n\n              <bean    id=\"myValueCalculator\"         class=\"x.y.z.MyValueCalculator\">\n                    <!--   arbitrary    method    replacement      -->\n                    <replaced-method       name=\"computeValue\"         replacer=\"replacementComputeValue\">\n                         <arg-type>String</arg-type>\n                    </replaced-method>\n              </bean>\n\n\n              <bean    id=\"replacementComputeValue\"           class=\"a.b.c.ReplacementComputeValue\"/>\n\n\n\n            You  can   use  one   or more    <arg-type/>    elements     within   the  <replaced-method/>       element    to indicate\n            the method signature of the method being overridden. The signature for the arguments is\n            necessary only if the method is overloaded and multiple variants exist within the class. For\n            convenience,     the  type  string  for  an  argument     may   be  a  substring   of  the  fully qualified   type   name.\n            For example,    the  following    all  match  java.lang.String:\n\n\n\n              java.lang.String\n              String\n              Str\n\n\n\n            Because   the  number     of arguments     is often  enough     to distinguish   between     each  possible   choice,   this\n            shortcut can save a lot of typing, by letting you type only the shortest string that matches an\n            argument     type.\n\n            2.1.5.   Bean     Scopes\n\n            When    you   create   a bean   definition,   you   create   a recipe   for  creating   actual   instances    of the  class\n            defined   by  that  bean   definition.   The  idea  that  a bean   definition    is a recipe   is  important,   because   it\n            means   that,  as with   a class, you  can  create   many    object  instances   from   a single  recipe.\n\n\n            You  can  control   not  only  the  various   dependencies      and   configuration     values   that are  to  be plugged\n            into an object that is created from a particular bean definition but also control the scope of the\n            objects  created   from    a particular   bean   definition.   This   approach    is powerful     and  flexible,  because\n            you  can  choose    the scope   of  the objects   you  create   through    configuration    instead   of  having   to bake\n            in the  scope   of  an  object  at  the  Java  class  level.  Beans   can   be  defined   to  be  deployed    in  one  of  a\n            number     of scopes.   The  Spring    Framework      supports    six scopes,   four   of which    are  available   only  if\n            you  use  a web-aware      ApplicationContext.      You  can  also  create  a custom    scope.\n\n            The  following   table  describes    the supported     scopes:\n\n\n            Table 3.

For\n                             more   information,     see  the  documentation       for  SimpleThreadScope.      For  instructions\n                              on how    to register  this or  any  other  custom    scope,  see  Using   a Custom    Scope.\n\n\n\n            The  Singleton    Scope\n\n            Only  one   shared   instance    of a singleton    bean   is  managed,   and   all requests   for  beans   with   an  ID  or\n            IDs that  match    that  bean   definition   result  in  that one   specific  bean   instance    being  returned    by  the\n            Spring  container.\n\n\n            To put  it another    way,  when    you  define   a bean   definition   and   it  is  scoped as a singleton,   the  Spring\n            IoC container    creates   exactly   one  instance    of the  object  defined   by  that  bean   definition.   This  single\n            instance   is stored   in a  cache   of such   singleton    beans,   and  all subsequent      requests   and   references\n            for that  named    bean   return   the  cached    object.  The  following    image   shows    how   the  singleton   scope\n            works:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n            Spring’s   concept   of  a singleton    bean   differs  from    the  singleton   pattern   as  defined    in the  Gang    of\n            Four  (GoF)   patterns    book.  The   GoF   singleton   hard-codes     the  scope   of  an  object  such   that  one  and\n\n            only  one  instance   of  a particular   class  is created   per  ClassLoader.     The  scope   of the  Spring   singleton\n            is  best  described  as being   per-container     and   per-bean.   This  means    that,  if  you  define one  bean   for  a\n            particular   class in  a single  Spring   container,   the  Spring   container    creates  one   and  only  one   instance\n            of the  class  defined   by  that  bean   definition.   The   singleton   scope   is the  default   scope   in Spring.   To\n            define  a bean   as  a singleton   in XML,   you   can  define  a bean   as  shown    in the  following   example:\n\n\n\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"/>\n\n\n              <!--   the   following    is   equivalent,     though    redundant    (singleton      scope   is  the  default)\n              -->\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"\n              scope=\"singleton\"/>\n\n\n\n\n            The  Prototype     Scope\n\n            The non-singleton prototype scope of bean deployment results in the creation of a new bean\n            instance every time a request for that specific bean is made. That is, the bean is injected into\n            another    bean   or  you  request    it through    a getBean()    method     call on  the  container.    As  a  rule,  you\n            should   use  the prototype    scope   for all stateful  beans   and   the singleton   scope   for  stateless  beans.\n\n\n            The  following   diagram     illustrates  the Spring   prototype    scope:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n            (A data   access  object   (DAO)   is not  typically   configured    as  a prototype,    because    a  typical  DAO    does\n            not hold   any  conversational     state. It was   easier  for us  to reuse  the  core  of the  singleton   diagram.)\n\n            The  following   example     defines   a bean   as a prototype    in XML:\n\n\n\n              <bean    id=\"accountService\"        class=\"com.something.DefaultAccountService\"\n              scope=\"prototype\"/>\n\n\n\n            In contrast   to the  other   scopes,  Spring   does   not  manage     the complete     lifecycle  of a prototype    bean.\n\n            The  container    instantiates,   configures,    and  otherwise     assembles    a  prototype    object  and   hands   it to\n            the client,  with   no  further   record   of that  prototype    instance.   Thus,   although    initialization   lifecycle\n            callback   methods    are  called  on  all objects   regardless    of scope,  in  the case  of  prototypes,    configured\n            destruction lifecycle callbacks are not called. The client code must clean up prototype-scoped\n            objects  and   release  expensive     resources    that  the  prototype    beans   hold.  To  get the  Spring   container\n            to release  resources    held  by  prototype-scoped      beans,   try  using  a custom    bean   post-processor,     which\n            holds  a reference    to beans   that  need   to be cleaned    up.\n\n\n            In some   respects,   the  Spring   container’s   role  in  regard   to a prototype-scoped       bean  is a  replacement\n            for the  Java  new  operator.    All lifecycle  management        past  that  point  must    be  handled    by  the  client.\n            (For details  on  the  lifecycle  of a bean   in the  Spring   container,   see  Lifecycle   Callbacks.)\n\n\n            Singleton    Beans   with   Prototype-bean       Dependencies\n\n            When you use singleton-scoped beans with dependencies on prototype beans, be aware that\n            dependencies     are  resolved    at instantiation    time.  Thus,   if  you dependency-inject      a  prototype-scoped\n            bean into a singleton-scoped bean, a new prototype bean is instantiated and then dependency-\n            injected  into  the  singleton   bean.   The  prototype    instance    is  the  sole  instance that  is ever  supplied    to\n            the singleton-scoped      bean.\n\n\n            However,    suppose    you   want   the  singleton-scoped      bean   to acquire   a  new   instance   of the  prototype-\n            scoped bean repeatedly at runtime. You cannot dependency-inject a prototype-scoped bean into\n            your   singleton     bean,    because    that   injection    occurs    only    once,   when     the   Spring    container\n            instantiates the singleton bean and resolves and injects its dependencies. If you need a new\n            instance   of a prototype    bean   at runtime    more   than   once,  see Method     Injection.\n\n\n            Request,    Session,   Application,     and   WebSocket      Scopes\n\n            The  request,   session,   application,    and   websocket   scopes   are   available   only  if you   use  a web-aware\n            Spring ApplicationContext implementation (such as XmlWebApplicationContext). If you use these\n            scopes    with   regular     Spring    IoC   containers,     such   as   the   ClassPathXmlApplicationContext,           an\n            IllegalStateException       that complains     about   an  unknown     bean   scope   is thrown.\n\n\n\n            Initial  Web Configuration\n\n            To support the scoping of beans at the request, session, application, and websocket levels (web-\n            scoped beans), some minor initial configuration is required before you define your beans. (This\n            initial setup  is not  required   for  the standard    scopes:   singleton   and   prototype.)\n\n\n            How   you  accomplish     this  initial setup  depends    on  your   particular   Servlet  environment.\n\n\n            If  you access  scoped    beans   within   Spring   Web    MVC,   in effect,  within   a request   that  is processed    by\n            the  Spring   DispatcherServlet,      no  special   setup   is necessary.   DispatcherServlet       already   exposes    all\n            relevant   state.\n\n\n            If  you use  a  Servlet   web   container,    with  requests    processed    outside   of  Spring’s   DispatcherServlet\n            (for     example,        when        using      JSF      or      Struts),     you       need       to     register      the\n            org.springframework.web.context.request.RequestContextListener ServletRequestListener. This can\n            be done    programmatically       by  using   the WebApplicationInitializer         interface.   Alternatively,    add  the\n            following   declaration    to your   web   application’s   web.xml   file:\n\n              <web-app>\n                    ...\n                    <listener>\n                         <listener-class>\n                               org.springframework.web.context.request.RequestContextListener\n                         </listener-class>\n                    </listener>\n                    ...\n              </web-app>\n\n\n\n            Alternatively,     if   there    are    issues     with    your     listener     setup,    consider      using    Spring’s\n            RequestContextFilter.        The    filter   mapping       depends      on   the    surrounding       web     application\n            configuration,    so you   have   to change    it  as  appropriate.  The  following    listing shows    the  filter part  of\n            a web   application:\n\n\n\n              <web-app>\n                    ...\n                    <filter>\n                         <filter-name>requestContextFilter</filter-name>\n                         <filter-class>org.springframework.web.filter.RequestContextFilter</filter-\n              class>\n                    </filter>\n                    <filter-mapping>\n                         <filter-name>requestContextFilter</filter-name>\n                         <url-pattern>/*</url-pattern>\n                    </filter-mapping>\n                    ...\n              </web-app>\n\n\n\n            DispatcherServlet,     RequestContextListener,        and   RequestContextFilter       all do  exactly   the  same   thing,\n            namely    bind  the  HTTP    request   object  to  the  Thread  that  is servicing   that  request.   This  makes    beans\n            that are  request-   and  session-scoped      available   further  down    the  call chain.\n\n\n\n            Request  scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"loginAction\"       class=\"com.something.LoginAction\"              scope=\"request\"/>\n\n\n\n            The  Spring   container    creates   a new   instance   of  the LoginAction     bean   by using   the  loginAction    bean\n            definition for each and every HTTP request. That is, the loginAction bean is scoped at the HTTP\n            request   level. You  can   change   the  internal   state of  the instance    that is created   as  much   as  you  want,\n            because other instances created from the same loginAction bean definition do not see these\n            changes in state. They are particular to an individual request. When the request completes\n            processing,   the  bean   that is scoped   to  the request   is discarded.\n\n\n            When    using  annotation-driven       components      or Java  configuration,     the  @RequestScope    annotation     can\n\n            be used   to assign  a  component     to the  request   scope.  The   following   example     shows   how   to do  so:\n\n\n            Java\n\n\n              @RequestScope\n              @Component\n              public    class   LoginAction      {\n                    //  ...\n              }\n\n\n\n            Kotlin\n\n\n              @RequestScope\n              @Component\n              class    LoginAction     {\n                    //  ...\n              }\n\n\n\n\n            Session  Scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\"/>\n\n\n\n            The   Spring     container     creates    a  new     instance    of   the   UserPreferences       bean    by   using    the\n            userPreferences bean definition for the lifetime of a single HTTP Session. In other words, the\n            userPreferences     bean   is effectively   scoped   at the  HTTP    Session   level. As  with   request-scoped     beans,\n            you  can  change    the  internal  state  of the  instance   that  is created   as much    as you   want,   knowing    that\n            other  HTTP    Session   instances    that  are  also  using  instances    created   from   the  same    userPreferences\n            bean  definition    do not  see  these  changes    in state,  because   they   are particular    to an  individual   HTTP\n            Session.  When     the  HTTP   Session   is eventually    discarded,    the  bean   that  is scoped   to  that  particular\n            HTTP   Session   is also discarded.\n\n\n            When using annotation-driven components or Java configuration, you can use the @SessionScope\n            annotation    to assign   a component      to the session   scope.\n\n\n            Java\n\n\n              @SessionScope\n              @Component\n              public    class   UserPreferences       {\n                    //  ...\n              }\n\n            Kotlin\n\n\n              @SessionScope\n              @Component\n              class    UserPreferences       {\n                    //  ...\n              }\n\n\n\n\n            Application  Scope\n\n            Consider   the  following    XML   configuration     for a bean   definition:\n\n\n\n              <bean    id=\"appPreferences\"        class=\"com.something.AppPreferences\"               scope=\"application\"/>\n\n\n\n            The  Spring   container    creates  a  new   instance   of the  AppPreferences     bean   by  using  the  appPreferences\n            bean  definition   once   for the  entire  web   application.    That  is, the appPreferences     bean   is scoped   at the\n            ServletContext     level  and  stored   as a  regular   ServletContext     attribute.  This  is somewhat      similar   to a\n            Spring  singleton    bean  but  differs  in two   important    ways:   It is  a singleton  per ServletContext,     not  per\n            Spring   ApplicationContext      (for  which   there   may   be  several   in any   given  web   application),    and   it  is\n            actually  exposed    and   therefore   visible  as a ServletContext     attribute.\n\n\n            When      using     annotation-driven        components         or   Java     configuration,      you     can    use    the\n            @ApplicationScope annotation to assign a component to the application scope. The following\n            example    shows   how    to do so:\n\n\n            Java\n\n\n              @ApplicationScope\n              @Component\n              public    class   AppPreferences       {\n                    //  ...\n              }\n\n\n\n            Kotlin\n\n\n              @ApplicationScope\n              @Component\n              class    AppPreferences      {\n                    //  ...\n              }\n\n\n\n\n            WebSocket    Scope\n\n            WebSocket     scope   is associated   with   the  lifecycle  of a WebSocket      session  and   applies   to STOMP     over\n            WebSocket     applications,   see  WebSocket     scope   for  more   details.\n\n            Scoped  Beans   as Dependencies\n\n            The  Spring   IoC  container     manages     not  only  the  instantiation    of  your   objects  (beans),   but  also  the\n            wiring   up  of collaborators     (or dependencies).      If  you want   to inject  (for  example)    an  HTTP    request-\n            scoped   bean   into  another    bean   of a  longer-lived    scope,  you   may   choose    to inject  an  AOP   proxy    in\n            place  of  the  scoped   bean.   That   is,  you need   to  inject  a proxy    object  that  exposes    the  same   public\n            interface as the scoped object but that can also retrieve the real target object from the relevant\n            scope  (such   as an  HTTP   request)   and   delegate   method    calls  onto  the  real object.\n\n\n                              You  may   also  use  <aop:scoped-proxy/>       between    beans   that  are  scoped   as  singleton,\n                              with  the  reference    then   going   through    an  intermediate     proxy    that  is serializable\n                              and  therefore   able  to  re-obtain   the target  singleton    bean  on  deserialization.\n\n\n                              When declaring <aop:scoped-proxy/> against a bean of scope prototype, every\n                              method    call on  the  shared    proxy   leads   to the  creation   of a  new   target  instance    to\n                              which   the  call is  then being  forwarded.\n\n                              Also, scoped    proxies   are  not  the only   way   to access  beans    from   shorter   scopes  in  a\n                              lifecycle-safe fashion. You may also declare your injection point (that is, the\n                             constructor    or setter  argument     or  autowired    field)  as ObjectFactory<MyTargetBean>,\n                              allowing   for  a  getObject()    call to  retrieve   the  current   instance    on  demand     every\n                              time  it  is  needed — without    holding    on to  the instance   or  storing  it separately.\n\n\n                              As an extended variant, you may declare ObjectProvider<MyTargetBean> which\n                              delivers    several     additional     access     variants,    including      getIfAvailable      and\n                              getIfUnique.\n\n\n                              The    JSR-330     variant     of   this    is   called    Provider     and     is   used    with     a\n                              Provider<MyTargetBean> declaration and a corresponding get() call for every\n                              retrieval  attempt.   See  here  for  more   details  on  JSR-330   overall.\n\n\n            The  configuration     in  the following    example     is only  one   line, but  it is important    to  understand     the\n            “why”   as well  as  the “how”    behind   it:\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:aop=\"http://www.springframework.org/schema/aop\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\n                         http://www.springframework.org/schema/aop\n                         https://www.springframework.org/schema/aop/spring-aop.xsd\">\n\n\n                    <!--   an  HTTP   Session-scoped      bean   exposed    as  a  proxy   -->\n                    <bean   id=\"userPreferences\"         class=\"com.something.UserPreferences\"               scope=\"session\">\n                         <!--   instructs     the  container     to  proxy    the  surrounding      bean  -->\n                         <aop:scoped-proxy/>         ①\n                    </bean>\n\n\n                    <!--   a singleton-scoped        bean   injected    with   a  proxy   to  the   above   bean   -->\n                    <bean   id=\"userService\"       class=\"com.something.SimpleUserService\">\n                         <!--   a  reference     to  the  proxied    userPreferences       bean   -->\n                         <property     name=\"userPreferences\"          ref=\"userPreferences\"/>\n                    </bean>\n              </beans>\n\n\n            ① The    line that  defines   the proxy.\n\n            To create   such  a proxy,   you  insert  a child  <aop:scoped-proxy/>       element    into  a scoped   bean   definition\n            (see Choosing the Type of Proxy to Create and XML Schema-based configuration). Why do\n            definitions   of beans   scoped   at  the request,   session   and  custom-scope      levels  require   the  <aop:scoped-\n            proxy/> element? Consider the following singleton bean definition and contrast it with what you\n            need to define for the aforementioned scopes (note that the following userPreferences bean\n            definition   as it  stands is incomplete):\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\"/>\n\n\n              <bean    id=\"userManager\"       class=\"com.something.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n            In the  preceding    example,    the  singleton   bean   (userManager)    is injected   with  a  reference   to  the HTTP\n            Session-scoped bean (userPreferences). The salient point here is that the userManager bean is a\n            singleton:   it  is  instantiated exactly   once   per  container,   and   its dependencies      (in this case   only  one,\n            the userPreferences bean) are also injected only once. This means that the userManager bean\n            operates   only  on  the  exact  same   userPreferences      object  (that  is,  the  one  with which   it was  originally\n            injected).\n\n            This  is not  the  behavior    you   want   when    injecting   a  shorter-lived    scoped    bean   into  a longer-lived\n            scoped   bean   (for  example,    injecting   an   HTTP   Session-scoped      collaborating     bean   as  a dependency\n            into singleton    bean).  Rather,   you   need   a single  userManager     object,  and,  for  the lifetime   of an  HTTP\n            Session,  you   need   a userPreferences      object  that  is specific  to the  HTTP    Session.   Thus,  the  container\n\n            creates  an  object   that  exposes   the  exact   same   public   interface   as  the  UserPreferences     class  (ideally\n            an  object  that  is a UserPreferences      instance),   which    can  fetch  the  real  UserPreferences      object  from\n            the scoping mechanism (HTTP request, Session, and so forth). The container injects this proxy\n            object  into the  userManager    bean,   which   is unaware     that  this UserPreferences     reference    is a proxy.   In\n            this  example,     when     a   UserManager     instance     invokes    a   method     on   the   dependency-injected\n            UserPreferences     object,  it is actually   invoking    a  method     on  the  proxy.   The  proxy    then  fetches   the\n            real UserPreferences object from (in this case) the HTTP Session and delegates the method\n            invocation    onto  the  retrieved   real UserPreferences      object.\n\n            Thus, you need the following (correct and complete) configuration when injecting request- and\n            session-scoped     beans   into collaborating     objects,  as the  following   example    shows:\n\n\n\n              <bean    id=\"userPreferences\"        class=\"com.something.UserPreferences\"                scope=\"session\">\n                    <aop:scoped-proxy/>\n              </bean>\n\n\n              <bean    id=\"userManager\"       class=\"com.something.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n\n            Choosing    the  Type   of  Proxy   to  Create\n\n            By default, when the Spring container creates a proxy for a bean that is marked up with the\n            <aop:scoped-proxy/>      element,    a CGLIB-based     class  proxy   is created.\n\n\n                              CGLIB   proxies   intercept    only  public   method    calls! Do   not  call non-public    methods\n                             on such   a proxy.   They  are  not  delegated    to the  actual  scoped   target  object.\n\n\n            Alternatively, you can configure the Spring container to create standard JDK interface-based\n            proxies   for such   scoped   beans,   by  specifying   false   for the  value   of the  proxy-target-class      attribute\n            of the  <aop:scoped-proxy/>      element.    Using   JDK  interface-based      proxies   means    that  you  do  not  need\n            additional   libraries   in your   application    classpath    to affect  such   proxying.    However,     it also  means\n            that the  class  of  the  scoped   bean   must    implement     at  least one   interface   and   that  all collaborators\n            into which    the  scoped    bean   is injected   must   reference    the  bean   through    one  of  its interfaces.   The\n            following   example    shows    a proxy   based   on  an  interface:\n\n\n\n              <!--   DefaultUserPreferences          implements     the  UserPreferences       interface     -->\n              <bean    id=\"userPreferences\"        class=\"com.stuff.DefaultUserPreferences\"                 scope=\"session\">\n                    <aop:scoped-proxy        proxy-target-class=\"false\"/>\n              </bean>\n\n\n              <bean    id=\"userManager\"       class=\"com.stuff.UserManager\">\n                    <property     name=\"userPreferences\"         ref=\"userPreferences\"/>\n              </bean>\n\n\n\n            For   more    detailed    information      about    choosing     class-based     or  interface-based      proxying,     see\n            Proxying    Mechanisms.\n\n            Custom    Scopes\n\n            The bean scoping mechanism is extensible. You can define your own scopes or even redefine\n            existing  scopes,   although    the  latter is considered     bad  practice   and   you  cannot    override   the  built-in\n            singleton   and   prototype   scopes.\n\n\n\n            Creating  a Custom   Scope\n\n            To   integrate    your    custom     scopes    into   the   Spring    container,     you    need    to   implement      the\n            org.springframework.beans.factory.config.Scope               interface,  which    is  described  in  this section.  For  an\n            idea  of how    to implement     your   own    scopes,  see  the  Scope   implementations       that  are  supplied    with\n            the Spring Framework itself and the Scope javadoc, which explains the methods you need to\n            implement     in more   detail.\n\n\n            The  Scope   interface   has  four  methods     to  get objects   from   the  scope,   remove    them    from   the  scope,\n            and  let them   be  destroyed.\n\n\n            The session scope implementation, for example, returns the session-scoped bean (if it does not\n            exist, the  method    returns   a new   instance   of  the bean,   after  having   bound    it  to  the  session  for  future\n            reference).   The  following    method    returns   the  object  from   the underlying     scope:\n\n\n            Java\n\n\n              Object    get(String     name,   ObjectFactory<?>        objectFactory)\n\n\n\n            Kotlin\n\n\n              fun   get(name:     String,    objectFactory:      ObjectFactory<*>):        Any\n\n\n\n            The session scope implementation, for example, removes the session-scoped bean from the\n            underlying    session.   The   object  should    be  returned,    but  you  can   return   null  if the  object   with  the\n            specified  name    is not  found.  The   following   method     removes    the  object  from   the underlying     scope:\n\n\n            Java\n\n\n              Object    remove(String      name)\n\n\n\n            Kotlin\n\n\n              fun   remove(name:      String):    Any\n\n\n\n            The following method registers a callback that the scope should invoke when it is destroyed or\n            when   the  specified   object  in the  scope   is  destroyed:\n\n\n            Java\n\n\n              void   registerDestructionCallback(String              name,    Runnable    destructionCallback)\n\n            Kotlin\n\n\n              fun   registerDestructionCallback(name:              String,    destructionCallback:        Runnable)\n\n\n\n            See the  javadoc   or  a Spring   scope   implementation      for  more   information     on  destruction    callbacks.\n\n            The  following   method     obtains   the conversation     identifier   for the  underlying    scope:\n\n\n            Java\n\n\n              String    getConversationId()\n\n\n\n            Kotlin\n\n\n              fun   getConversationId():         String\n\n\n\n            This  identifier  is different   for  each   scope.  For  a  session   scoped   implementation,       this identifier   can\n            be the  session   identifier.\n\n\n\n            Using a Custom    Scope\n\n            After  you  write   and   test one  or  more   custom    Scope   implementations,       you  need   to make    the  Spring\n            container   aware    of your   new   scopes.   The  following    method    is the  central   method    to register   a new\n            Scope  with  the  Spring   container:\n\n\n            Java\n\n\n              void   registerScope(String         scopeName,     Scope   scope);\n\n\n\n            Kotlin\n\n\n              fun   registerScope(scopeName:          String,    scope:    Scope)\n\n\n\n            This  method     is declared   on   the  ConfigurableBeanFactory        interface,   which    is available   through    the\n            BeanFactory property on most of the concrete ApplicationContext implementations that ship with\n            Spring.\n\n\n            The  first argument      to the  registerScope(..)       method    is the  unique    name    associated    with   a  scope.\n            Examples of such names in the Spring container itself are singleton and prototype. The second\n            argument      to   the   registerScope(..)        method      is   an   actual    instance     of   the   custom      Scope\n            implementation      that  you  wish   to register  and   use.\n\n            Suppose that you write your custom Scope implementation, and then register it as shown in the\n            next  example.\n\n                              The  next  example     uses  SimpleThreadScope,      which   is included    with  Spring   but  is not\n                             registered by default. The instructions would be the same for your own custom\n                              Scope  implementations.\n\n\n            Java\n\n\n              Scope    threadScope     =  new  SimpleThreadScope();\n              beanFactory.registerScope(\"thread\",               threadScope);\n\n\n\n            Kotlin\n\n\n              val   threadScope     =  SimpleThreadScope()\n              beanFactory.registerScope(\"thread\",               threadScope)\n\n\n\n            You can then create bean definitions that adhere to the scoping rules of your custom Scope, as\n            follows:\n\n\n\n              <bean    id=\"...\"    class=\"...\"     scope=\"thread\">\n\n\n\n            With  a  custom   Scope   implementation,      you  are  not  limited   to programmatic      registration    of the  scope.\n            You  can  also  do  the  Scope  registration   declaratively,    by  using  the  CustomScopeConfigurer       class,  as the\n            following   example    shows:\n\n              <?xml    version=\"1.0\"      encoding=\"UTF-8\"?>\n              <beans    xmlns=\"http://www.springframework.org/schema/beans\"\n                    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n                    xmlns:aop=\"http://www.springframework.org/schema/aop\"\n                    xsi:schemaLocation=\"http://www.springframework.org/schema/beans\n                         https://www.springframework.org/schema/beans/spring-beans.xsd\n                         http://www.springframework.org/schema/aop\n                         https://www.springframework.org/schema/aop/spring-aop.xsd\">\n\n\n                    <bean   class=\"org.springframework.beans.factory.config.CustomScopeConfigurer\">\n                         <property     name=\"scopes\">\n                               <map>\n                                    <entry    key=\"thread\">\n                                          <bean\n              class=\"org.springframework.context.support.SimpleThreadScope\"/>\n                                    </entry>\n                               </map>\n                         </property>\n                    </bean>\n\n\n                    <bean   id=\"thing2\"      class=\"x.y.Thing2\"        scope=\"thread\">\n                         <property     name=\"name\"      value=\"Rick\"/>\n                         <aop:scoped-proxy/>\n                    </bean>\n\n\n                    <bean   id=\"thing1\"      class=\"x.y.Thing1\">\n                         <property     name=\"thing2\"      ref=\"thing2\"/>\n                    </bean>\n\n\n              </beans>\n\n\n\n\n                              When    you  place   <aop:scoped-proxy/>       within   a <bean>   declaration    for a  FactoryBean\n                             implementation,      it is the factory   bean   itself that  is scoped,   not  the  object  returned\n                              from  getObject().\n\n\n            2.1.6.   Customizing          the   Nature       of  a Bean\n\n            The  Spring   Framework       provides    a number     of  interfaces   you   can  use  to  customize    the  nature   of  a\n            bean.  This  section   groups   them   as follows:\n\n              • Lifecycle   Callbacks\n\n              • ApplicationContextAware        and  BeanNameAware\n\n              • Other   Aware  Interfaces\n\n\n            Lifecycle   Callbacks\n\n            To  interact  with   the  container’s    management       of  the bean    lifecycle,  you  can   implement     the  Spring\n            InitializingBean and DisposableBean interfaces. The container calls afterPropertiesSet() for the\n\n            former   and   destroy()    for the  latter  to let the  bean   perform     certain  actions   upon    initialization  and\n            destruction    of your  beans.\n\n\n                              The  JSR-250   @PostConstruct      and  @PreDestroy     annotations     are  generally   considered\n                              best practice   for receiving    lifecycle  callbacks   in a modern     Spring   application.   Using\n                              these annotations means that your beans are not coupled to Spring-specific\n                             interfaces.  For  details,  see Using   @PostConstruct     and   @PreDestroy.\n\n\n                              If you do not want to use the JSR-250 annotations but you still want to remove\n                              coupling,   consider   init-method    and   destroy-method     bean   definition   metadata.\n\n\n            Internally,  the  Spring   Framework       uses  BeanPostProcessor       implementations       to process   any   callback\n            interfaces it can find and call the appropriate methods. If you need custom features or other\n            lifecycle  behavior    Spring  does   not  by default   offer, you   can  implement     a BeanPostProcessor      yourself.\n            For more    information,    see  Container    Extension    Points.\n\n\n            In addition to the initialization and destruction callbacks, Spring-managed objects may also\n            implement     the  Lifecycle   interface   so  that those   objects  can  participate    in the  startup  and   shutdown\n            process,  as  driven   by the  container’s    own   lifecycle.\n\n\n            The  lifecycle  callback   interfaces   are  described    in this section.\n\n\n\n            Initialization Callbacks\n\n            The     org.springframework.beans.factory.InitializingBean                   interface     lets    a    bean      perform\n            initialization    work    after   the   container     has   set   all  necessary     properties     on   the   bean.    The\n            InitializingBean     interface   specifies   a single  method:\n\n\n\n              void   afterPropertiesSet()         throws    Exception;\n\n\n\n            We  recommend       that  you  do  not  use  the InitializingBean      interface,   because   it unnecessarily     couples\n            the code to Spring. Alternatively, we suggest using the @PostConstruct annotation or specifying a\n            POJO   initialization  method.    In  the  case  of XML-based      configuration    metadata,    you   can  use  the  init-\n            method attribute to specify the name of the method that has a void no-argument signature. With\n            Java  configuration,    you   can  use  the  initMethod    attribute   of @Bean.  See  Receiving    Lifecycle   Callbacks.\n            Consider   the  following    example:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.ExampleBean\"            init-method=\"init\"/>\n\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    public   void   init()    {\n                         //  do   some  initialization       work\n                    }\n              }\n\n            Kotlin\n\n\n              class    ExampleBean     {\n\n\n                    fun  init()    {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            The  preceding    example     has  almost   exactly  the  same   effect  as the  following    example    (which   consists\n            of two  listings):\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.AnotherExampleBean\"/>\n\n\n\n            Java\n\n\n              public    class   AnotherExampleBean        implements     InitializingBean        {\n\n\n                    @Override\n                    public   void   afterPropertiesSet()         {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    AnotherExampleBean        : InitializingBean        {\n\n\n                    override    fun   afterPropertiesSet()         {\n                         //  do   some  initialization       work\n                    }\n              }\n\n\n\n            However,    the  first of the  two  preceding    examples     does  not  couple   the  code  to Spring.\n\n\n\n            Destruction   Callbacks\n\n            Implementing the org.springframework.beans.factory.DisposableBean interface lets a bean get a\n            callback   when    the  container    that  contains   it is destroyed.    The   DisposableBean     interface   specifies   a\n            single  method:\n\n\n\n              void   destroy()     throws    Exception;\n\n\n\n            We  recommend       that  you   do  not  use  the DisposableBean      callback   interface,  because    it unnecessarily\n            couples   the  code  to Spring.   Alternatively,    we  suggest   using   the @PreDestroy     annotation    or  specifying\n            a generic   method     that  is supported     by  bean   definitions.   With   XML-based      configuration     metadata,\n            you  can   use  the  destroy-method     attribute   on  the  <bean/>.   With   Java  configuration,     you   can  use  the\n\n            destroyMethod      attribute    of  @Bean.   See    Receiving     Lifecycle    Callbacks.    Consider     the   following\n            definition:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.ExampleBean\"            destroy-method=\"cleanup\"/>\n\n\n\n            Java\n\n\n              public    class   ExampleBean      {\n\n\n                    public   void   cleanup()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    ExampleBean     {\n\n\n                    fun  cleanup()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            The  preceding    definition   has  almost   exactly   the same    effect as  the following    definition:\n\n\n\n              <bean    id=\"exampleInitBean\"        class=\"examples.AnotherExampleBean\"/>\n\n\n\n            Java\n\n\n              public    class   AnotherExampleBean        implements     DisposableBean       {\n\n\n                    @Override\n                    public   void   destroy()     {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n\n\n            Kotlin\n\n\n              class    AnotherExampleBean        : DisposableBean       {\n\n\n                    override    fun   destroy()    {\n                         //  do   some  destruction      work   (like   releasing     pooled   connections)\n                    }\n              }\n\n            However,    the  first of the  two  preceding    definitions   does   not  couple   the code   to Spring.\n\n\n                              You  can  assign   the destroy-method     attribute   of a <bean>   element    a special  (inferred)\n                              value, which instructs Spring to automatically detect a public close or shutdown\n                              method       on     the    specific     bean      class.     (Any     class     that    implements\n                              java.lang.AutoCloseable or java.io.Closeable would therefore match.) You can\n                             also  set this  special  (inferred)    value   on  the  default-destroy-method        attribute   of  a\n                              <beans> element to apply this behavior to an entire set of beans (see Default\n                              Initialization  and   Destroy   Methods).    Note   that this  is  the  default behavior   with   Java\n                              configuration.\n\n\n\n            Default  Initialization and  Destroy  Methods\n\n            When you write initialization and destroy method callbacks that do not use the Spring-specific\n            InitializingBean      and  DisposableBean      callback   interfaces,   you   typically   write  methods     with   names\n            such as init(), initialize(), dispose(), and so on. Ideally, the names of such lifecycle callback\n            methods    are  standardized      across  a  project  so  that  all developers    use   the same    method    names    and\n            ensure   consistency.\n\n\n            You can configure the Spring container to “look” for named initialization and destroy callback\n            method names on every bean. This means that you, as an application developer, can write your\n            application    classes  and   use  an  initialization   callback   called  init(),   without   having    to configure    an\n            init-method=\"init\"      attribute   with  each   bean   definition.   The  Spring    IoC container    calls  that  method\n            when   the  bean   is created   (and  in accordance     with   the standard    lifecycle  callback   contract   described\n            previously).   This  feature   also enforces    a consistent   naming     convention    for  initialization   and  destroy\n            method    callbacks.\n\n            Suppose that your initialization callback methods are named init() and your destroy callback\n            methods    are  named    destroy().   Your   class then   resembles    the  class  in the following    example:\n\n\n            Java\n\n\n              public    class   DefaultBlogService        implements     BlogService      {\n\n\n                    private    BlogDao    blogDao;\n\n\n                    public   void   setBlogDao(BlogDao        blogDao)     {\n                         this.blogDao      =  blogDao;\n                    }\n\n\n                    //  this   is  (unsurprisingly)       the   initialization      callback     method\n                    public   void   init()    {\n                         if  (this.blogDao       ==  null)   {\n                               throw   new   IllegalStateException(\"The           [blogDao]    property     must   be  set.\");\n                         }\n                    }\n              }\n\n            Kotlin\n\n\n              class    DefaultBlogService        : BlogService      {\n\n\n                    private    var  blogDao:     BlogDao?    =  null\n\n\n                    //  this   is  (unsurprisingly)       the   initialization      callback     method\n                    fun  init()    {\n                         if  (blogDao     ==  null)   {\n                               throw   IllegalStateException(\"The           [blogDao]     property    must   be  set.\")\n                         }\n                    }\n              }\n\n\n\n            You  could  then   use  that class  in a bean   resembling     the  following:\n\n\n\n              <beans    default-init-method=\"init\">\n\n\n                    <bean   id=\"blogService\"       class=\"com.something.DefaultBlogService\">\n                         <property     name=\"blogDao\"       ref=\"blogDao\"      />\n                    </bean>\n\n\n              </beans>\n\n\n\n            The  presence    of the  default-init-method      attribute   on  the  top-level  <beans/>    element   attribute   causes\n            the  Spring   IoC  container    to recognize     a method     called  init  on  the  bean    class  as the  initialization\n            method    callback.   When    a  bean   is  created  and  assembled,     if the bean    class has   such  a  method,    it  is\n            invoked   at the  appropriate     time.\n\n\n            You can configure destroy method callbacks similarly (in XML, that is) by using the default-\n            destroy-method     attribute  on  the  top-level  <beans/>    element.\n\n\n            Where    existing   bean   classes   already   have   callback    methods    that  are   named    at  variance    with  the\n            convention,    you   can  override   the  default   by  specifying   (in  XML,   that  is) the method     name    by using\n            the init-method    and   destroy-method     attributes   of the  <bean/>  itself.\n\n\n            The  Spring   container    guarantees    that  a configured    initialization   callback   is called  immediately     after\n            a bean   is supplied   with   all dependencies.     Thus,   the  initialization  callback    is  called on  the raw   bean\n            reference,   which   means    that  AOP   interceptors    and   so forth  are  not  yet  applied   to the  bean.  A  target\n            bean  is fully  created   first and  then  an  AOP   proxy   (for  example)    with  its interceptor    chain   is  applied.\n            If  the  target bean   and  the  proxy    are  defined   separately,   your   code   can  even   interact   with  the  raw\n            target  bean,   bypassing    the  proxy.   Hence,   it would    be  inconsistent    to  apply   the  interceptors    to the\n            init method, because doing so would couple the lifecycle of the target bean to its proxy or\n            interceptors and leave strange semantics when your code interacts directly with the raw target\n            bean."

    "content": "The Great Depression (1929–1939) was an economic shock that affected most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States.[1] The economic contagion began around September 1929 and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century.[2]\nBetween 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession.[3] Some economies started to recover by the mid-1930s. However, in many countries,[specify] the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and in some countries rose as high as 33%.[4]\nCities around the world were hit hard, especially those dependent on heavy industry. Construction was virtually halted in many countries. Farming communities and rural areas suffered as crop prices fell by about 60%.[5][6][7] Faced with plummeting demand and few job alternatives, areas dependent on primary sector industries suffered the most.[8]\nEconomic historians usually consider the catalyst of the Great Depression to be the sudden devastating collapse of U.S. stock market prices, starting on October 24, 1929. However, some dispute this conclusion, seeing the stock crash less than a cause of the Depression and more as a symptom of the rising nervousness of investors partly due to gradual price declines caused by falling sales of consumer goods (as a result of overproduction because of new production techniques, falling exports and income inequality, among other factors) that had already been underway as part of a gradual Depression"

    "content": "The Spring AI project aims to streamline the development of applications that incorporate artificial intelligence functionality without unnecessary complexity.\nThe project draws inspiration from notable Python projects, such as LangChain and LlamaIndex, but Spring AI is not a direct port of those projects. The project was founded with the belief that the next wave of Generative AI applications will not be only for Python developers but will be ubiquitous across many programming languages.\nAt its core, Spring AI provides abstractions that serve as the foundation for developing AI applications. These abstractions have multiple implementations, enabling easy component swapping with minimal code changes. For example, Spring AI introduces the ChatModel interface with implementations for OpenAI and Azure OpenAI.\nIn addition to these core abstractions, Spring AI aims to provide higher-level functionalities to address common use cases such as “Q&A over your documentation” or “Chat with your documentation.” As the complexity of the use cases increases, the Spring AI project will integrate with other projects in the Spring Ecosystem, such as Spring Integration, Spring Batch, and Spring Data.\nTo simplify setup, Spring Boot starters are available to help set up essential dependencies and classes. There is also a collection of sample applications to help you explore the project’s features. Lastly, the new Spring CLI project also enables you to get started quickly by using the spring boot new AI command for new projects or spring boot add AI for adding AI capabilities to your existing application.\n\n"

Queries CI status for each monitored repository\n2. Updates the [Wiki Dashboard](https://github.com/spring-projects/spring-ai/wiki/Ecosystem-CI-Dashboard) with current status\n3. Posts alerts to [Issue #5334](https://github.com/spring-projects/spring-ai/issues/5334) when dependencies fail for extended periods\n\n## Subscribing to Alerts\n\nTo receive notifications when ecosystem dependencies fail CI:\n\n1. Go to [Issue #5334](https://github.com/spring-projects/spring-ai/issues/5334)\n2. Click **Subscribe** in the right sidebar\n3. You'll receive GitHub notifications when alerts are posted\n\n## Alert Policy\n\n| Condition | Action |\n|-----------|--------|\n| Dependency fails (day 1) | Dashboard updated, no alert |\n| Dependency fails for 2+ days | Alert comment posted (triggers notification) |\n| Dependency recovers | Dashboard updated, no alert |\n\nThe `alert_after_days` setting in `ci-alert-config.json` controls the threshold (default: 2 days).\n\n## Adding or Removing Dependencies\n\nEdit `ci-alert-config.json`:\n\n```json\n{\n  \"dependencies\": [\n    { \"owner\": \"org-name\", \"repo\": \"repo-name\" },\n    ...\n  ]\n}\n```\n\nEach dependency must have:\n- `owner`: GitHub organization or user\n- `repo`: Repository name\n\nThe workflow monitors the branch specified by `tracked_branch` (default: `main`).\n\n## Configuration Reference\n\n| Field | Description | Default |\n|-------|-------------|---------|\n| `issue_number` | GitHub issue for dashboard and alerts | 5334 |\n| `tracked_branch` | Branch to monitor for each repo | main |\n| `alert_after_days` | Days of failure before alerting | 2 |\n| `heartbeat_days` | Minimum days between repeat alerts | 1 |\n\n## Manual Trigger\n\nTo run the dashboard manually:\n\n1. Go to [Actions > Ecosystem CI Dashboard](https://github.com/spring-projects/spring-ai/actions/workflows/dependency-ci-dashboard.yml)\n2. Click **Run workflow**\n3. Select the `main` branch and click **Run workflow**\n\n## Files\n\n- `ci-alert-config.json` - Dashboard configuration\n- `../../.github/workflows/dependency-ci-dashboard.yml` - GitHub Actions workflow\n"

It offers functionalities like adding, deleting, and performing\n * similarity searches on documents.\n *\n * The store utilizes CQL to index and search vector data. It allows for custom metadata\n * fields in the documents to be stored alongside the vector and content data.\n *\n * This class requires a CassandraVectorStore#CassandraBuilder configuration object for\n * initialization, which includes settings like connection details, index name, column\n * names, etc. It also requires an EmbeddingModel to convert documents into embeddings\n * before storing them.\n *\n * A schema matching the configuration is automatically created if it doesn't exist.\n * Missing columns and indexes in existing tables will also be automatically created.\n * Disable this with the CassandraBuilder#initializeSchema(boolean) method().\n *\n * <p>\n * Basic usage example:\n * </p>\n * <pre>{@code\n * CassandraVectorStore vectorStore = CassandraVectorStore.builder(embeddingModel)\n *     .session(cqlSession)\n *     .keyspace(\"my_keyspace\")\n *     .table(\"my_vectors\")\n *     .build();\n *\n * // Add documents\n * vectorStore.add(List.of(\n *     new Document(\"1\", \"content1\", Map.of(\"key1\", \"value1\")),\n *     new Document(\"2\", \"content2\", Map.of(\"key2\", \"value2\"))\n * ));\n *\n * // Search with filters\n * List<Document> results = vectorStore.similaritySearch(\n *     SearchRequest.query(\"search text\")\n *         .withTopK(5)\n *         .withSimilarityThreshold(0.7)\n *         .withFilterExpression(\"metadata.key1 == 'value1'\")\n * );\n * }</pre>\n *\n * <p>\n * Advanced configuration example:\n * </p>\n * <pre>{@code\n * CassandraVectorStore vectorStore = CassandraVectorStore.builder(embeddingModel)\n *     .session(cqlSession)\n *     .keyspace(\"my_keyspace\")\n *     .table(\"my_vectors\")\n *     .partitionKeys(List.of(new SchemaColumn(\"id\", DataTypes.TEXT)))\n *     .clusteringKeys(List.of(new SchemaColumn(\"timestamp\", DataTypes.TIMESTAMP)))\n *     .addMetadataColumns(\n *         new SchemaColumn(\"category\", DataTypes.TEXT, SchemaColumnTags.INDEXED),\n *         new SchemaColumn(\"score\", DataTypes.DOUBLE)\n *     )\n *     .contentColumnName(\"text\")\n *     .embeddingColumnName(\"vector\")\n *     .fixedThreadPoolExecutorSize(32)\n *     .initializeSchema(true)\n *     .batchingStrategy(new TokenCountBatchingStrategy())\n *     .build();\n * }</pre>\n *\n * This class is designed to work with brand new tables that it creates for you, or on top\n * of existing Cassandra tables. The latter is appropriate when wanting to keep data in\n * place, creating embeddings next to it, and performing vector similarity searches\n * in-situ.\n *\n * Instances of this class are not dynamic against server-side schema changes. If you\n * change the schema server-side you need a new CassandraVectorStore instance.\n *\n * When adding documents with the method {@link #add(List<Document>)} it first calls\n * embeddingModel to create the embeddings. This is slow. Configure\n * {@link Builder#fixedThreadPoolExecutorSize(int)} accordingly to improve performance so\n * embeddings are created and the documents are added concurrently. The default\n * concurrency is 16 ({@link Builder#DEFAULT_ADD_CONCURRENCY}). Remote transformers\n * probably want higher concurrency, and local transformers may need lower concurrency.\n * This concurrency limit does not need to be higher than the max parallel calls made to\n * the {@link #add(List<Document>)} method multiplied by the list size. This setting can\n * also serve as a protecting throttle against your embedding model.\n *\n * @author Mick Semb Wever\n * @author Christian Tzolov\n * @author Thomas Vitale\n * @author Soby Chacko\n

It is the fourth-largest planet in the system. Neptunes mass is 17 times Earths mass and a little bit more than Uranus mass. Neptune is denser and smaller than Uranus. Because of its greater mass, Neptunes gravity makes its atmosphere smaller and denser. It was named after the Roman god of the sea, Neptune. Neptunes astronomical symbol is ♆, the trident of the god Neptune. Neptunes atmosphere is mostly hydrogen and helium. It also contains small amounts of methane which makes the planet appear blue. Neptunes blue color is similar, but slightly darker, than the color of Uranus. Neptune also has the strongest winds of any planet in the Solar System, as high as 2,100\\\\xa0km/h or 1,300\\\\xa0mph.

Urbain Le Verrier and John Couch Adams were the astronomers who discovered Neptune. Neptune was not discovered using a telescope. It was the first planet to be discovered using mathematics. In 1821, astronomers saw that Uranus orbit was different from what they expected. Another nearby planets mass was changing Uranus orbit. They found Neptune was the cause. Voyager 2 visited Neptune on 25 August 1989. It was the only spacecraft to visit the planet. Neptune used to have a huge storm known as the \\\"Great Dark Spot\\\". Voyager 2 discovered the spot in 1989. The dark spot was not seen in 1994, but new spots were found since then. It is not known why the dark spot disappeared.

He saw it on 28 December 1612 and 27 January 1613. His drawings showed points near Jupiter where Neptune is placed. But Galileo was not credited for the discovery. He thought Neptune was a \\\"fixed star\\\" instead of a planet. Because Neptune slowly moved across the sky, Galileos small telescope was not strong enough to see that Neptune was a planet. In 1821, Alexis Bouvard published the astronomical tables of the orbit of Uranus. Later observations showed that Uranus was moving in an irregular way in its orbit. Some astronomers thought this was caused by another large body. In 1843, John Couch Adams calculated the orbit of an eighth planet that could possibly affect the orbit of Uranus. He sent his calculations to Sir George Airy, the\",\n\t\t\t\t\tMap.of(\"revision\", 9385813, \"id\", 558)));\n\n\tprivate static final String URANUS_ORBIT_QUERY = \"It was the first planet to be discovered using mathematics.

Similarity search, a key\n * functionality of vector databases, complements traditional relational databases as well\n * as full-text search systems. Using natural language text as an example, embedding\n * functions map data to high dimensional vectors to preserve their semantic similarity.\n * Developers can then use vector-based semantic search to find similarity between\n * different passages of text. Because the data within an LLM is current only up to a\n * specific point in time, vector databases can offer additional relevant text to make\n * searches more accurate – known as <b>Retrieval Augmented Generation</b> (RAG).\n * Therefore, the addition of RAG to an LLM using a vector database like SAP HANA Cloud\n * provides an effective approach to increase the quality of responses from an LLM.\n *\n * The SAP HANA Cloud vector engine supports the create, read, update, and delete (CRUD)\n * operations involving vectors using SQL.\n *\n * <code>HanaCloudVectorStore</code> is an implementation of\n * <code>org.springframework.ai.vectorstore.VectorStore</code> interface that provides\n * implementation of <code>COSINE_SIMILARITY</code> function introduced in HanaDB in Mar,\n * 2024\n *\n * Hana DB introduced a new datatype <code>REAL_VECTOR</code> that can store embeddings\n * generated by <code>org.springframework.ai.embedding.EmbeddingModel</code>\n *\n * @author Rahul Mittal\n * @author Christian Tzolov\n * @author Sebastien Deleuze\n * @author Soby Chacko\n * @see <a href=\n * \"https://help.sap.com/docs/hana-cloud-database/sap-hana-cloud-sap-hana-database-vector-engine-guide/introduction\">SAP\n * HANA Database Vector Engine Guide</a>\n * @since 1.0.0\n */\npublic class HanaCloudVectorStore extends AbstractObservationVectorStore {\n\n\tprivate static final Logger logger = LoggerFactory.getLogger(HanaCloudVectorStore.class);\n\n\tprivate final HanaVectorRepository<? extends HanaVectorEntity> repository;\n\n\tprivate final String tableName;\n\n\tprivate final int topK;\n\n\tprivate final JsonMapper jsonMapper;\n\n\t/**\n\t * Protected constructor that accepts a builder instance.

    "content": "# Redis Semantic Cache for Spring AI\n\nThis module provides a Redis-based implementation of semantic caching for Spring AI.\n\n## Overview\n\nSemantic caching allows storing and retrieving chat responses based on the semantic similarity of user queries.\nThis implementation uses Redis vector search capabilities to efficiently find similar queries and return cached responses.\n\n## Features\n\n- Store chat responses with their associated queries in Redis\n- Retrieve responses based on semantic similarity\n- Support for time-based expiration of cached entries\n- Includes a ChatClient advisor for automatic caching\n- Built on Redis vector search technology\n\n## Requirements\n\n- Redis Stack with Redis Query Engine and RedisJSON modules\n- Java 17 or later\n- Spring AI core dependencies\n- An embedding model for vector generation\n\n## Usage\n\n### Maven Configuration\n\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-redis-semantic-cache</artifactId>\n</dependency>\n```\n\nFor Spring Boot applications, you can use the starter:\n\n```xml\n<dependency>\n    <groupId>org.springframework.ai</groupId>\n    <artifactId>spring-ai-starter-vector-store-redis-semantic-cache</artifactId>\n</dependency>\n```\n\n### Basic Usage\n\n```java\n// Create Redis client\nJedisPooled jedisClient = new JedisPooled(\"localhost\", 6379);\n\n// Create the embedding model\nEmbeddingModel embeddingModel = new OpenAiEmbeddingModel(apiKey);\n\n// Create the semantic cache\nSemanticCache semanticCache = DefaultSemanticCache.builder()\n    .jedisClient(jedisClient)\n    .embeddingModel(embeddingModel)\n    .similarityThreshold(0.85) // Optional: adjust similarity threshold (0-1)\n    .build();\n\n// Create the cache advisor\nSemanticCacheAdvisor cacheAdvisor = SemanticCacheAdvisor.builder()\n    .cache(semanticCache)\n    .build();\n\n// Use with ChatClient\nChatResponse response = ChatClient.builder(chatModel)\n    .build()\n    .prompt(\"What is the capital of France?\")\n    .advisors(cacheAdvisor) // Add the advisor\n    .call()\n    .chatResponse();\n```\n\n### Direct Cache Usage\n\nYou can also use the cache directly:\n\n```java\n// Store a response\nsemanticCache.set(\"What is the capital of France?\", parisResponse);\n\n// Store with expiration\nsemanticCache.set(\"What's the weather today?\", weatherResponse, Duration.ofHours(1));\n\n// Retrieve a semantically similar response\nOptional<ChatResponse> response = semanticCache.get(\"Tell me the capital city of France\");\n\n// Clear the cache\nsemanticCache.clear();\n```\n\n## Configuration Options\n\nThe `DefaultSemanticCache` can be configured with the following options:\n\n- `jedisClient` - The Redis client\n- `vectorStore` - Optional existing vector store to use\n- `embeddingModel` - The embedding model for vector generation\n- `similarityThreshold` - Threshold for determining similarity (0-1)\n- `indexName` - The name of the Redis search index\n- `prefix` - Key prefix for Redis documents\n\n## Spring Boot Integration\n\nWhen using Spring Boot and the Redis Semantic Cache starter, the components will be automatically configured.\nYou can customize behavior using properties in `application.properties` or `application.yml`:\n\n```yaml\nspring:\n  ai:\n    vectorstore:\n      redis:\n        semantic-cache:\n          host: localhost\n          port: 6379\n          similarity-threshold: 0.85\n          index-name: semantic-cache\n```"

    "content": "# Spring AI Redis Vector Store\n\nA Redis-based vector store implementation for Spring AI using Redis Stack with Redis Query Engine and RedisJSON.\n\n## Documentation\n\nFor comprehensive documentation, see\nthe [Redis Vector Store Documentation](https://docs.spring.io/spring-ai/reference/api/vectordbs/redis.html).\n\n## Features\n\n- Vector similarity search using KNN\n- Range-based vector search with radius threshold\n- Text-based search on TEXT fields\n- Support for multiple distance metrics (COSINE, L2, IP)\n- Multiple text scoring algorithms (BM25, TFIDF, etc.)\n- HNSW and FLAT vector indexing algorithms\n- Configurable metadata fields (TEXT, TAG, NUMERIC)\n- Filter expressions for advanced filtering\n- Batch processing support\n\n## Usage\n\n### KNN Search\n\nThe standard similarity search returns the k-nearest neighbors:\n\n```java\n// Create the vector store\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .indexName(\"my-index\")\n    .vectorAlgorithm(Algorithm.HNSW)\n    .distanceMetric(DistanceMetric.COSINE)\n    .build();\n\n// Add documents\nvectorStore.add(List.of(\n    new Document(\"content1\", Map.of(\"category\", \"AI\")),\n    new Document(\"content2\", Map.of(\"category\", \"DB\"))\n));\n\n// Search with KNN\nList<Document> results = vectorStore.similaritySearch(\n    SearchRequest.builder()\n        .query(\"AI and machine learning\")\n        .topK(5)\n        .similarityThreshold(0.7)\n        .filterExpression(\"category == 'AI'\")\n        .build()\n);\n```\n\n### Text Search\n\nThe text search capability allows you to find documents based on keywords and phrases in TEXT fields:\n\n```java\n// Search for documents containing specific text\nList<Document> textResults = vectorStore.searchByText(\n    \"machine learning\",   // search query\n    \"content\",            // field to search (must be TEXT type)\n    10,                   // limit\n    \"category == 'AI'\"    // optional filter expression\n);\n```\n\nText search supports:\n\n- Single word searches\n- Phrase searches with exact matching when `inOrder` is true\n- Term-based searches with OR semantics when `inOrder` is false\n- Stopword filtering to ignore common words\n- Multiple text scoring algorithms (BM25, TFIDF, DISMAX, etc.)\n\nConfigure text search behavior at construction time:\n\n```java\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .textScorer(TextScorer.TFIDF)                    // Text scoring algorithm\n    .inOrder(true)                                   // Match terms in order\n    .stopwords(Set.of(\"is\", \"a\", \"the\", \"and\"))      // Ignore common words\n    .metadataFields(MetadataField.text(\"description\")) // Define TEXT fields\n    .build();\n```\n\n### Range Search\n\nThe range search returns all documents within a specified radius:\n\n```java\n// Search with radius\nList<Document> rangeResults = vectorStore.searchByRange(\n    \"AI and machine learning\",  // query\n    0.8,                        // radius (similarity threshold)\n    \"category == 'AI'\"          // optional filter expression\n);\n```\n\nYou can also set a default range threshold at construction time:\n\n```java\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .defaultRangeThreshold(0.8)  // Set default threshold\n    .build();\n\n// Use default threshold\nList<Document> results = vectorStore.searchByRange(\"query\");\n```\n\n## Configuration Options\n\nThe Redis Vector Store supports multiple configuration options:\n\n```java\nRedisVectorStore vectorStore = RedisVectorStore.builder(jedisPooled, embeddingModel)\n    .indexName(\"custom-index\")        // Redis index name\n    .prefix(\"custom-prefix\")          // Redis key prefix\n    .contentFieldName(\"content\")      // Field for document content\n    .embeddingFieldName(\"embedding\")  // Field for vector embeddings\n    .vectorAlgorithm(Algorithm.HNSW)  // Vector algorithm (HNSW or FLAT)\n    .distanceMetric(DistanceMetric.COSINE) // Distance metric\n    .hnswM(32)                        // HNSW parameter for connections\n    .hnswEfConstruction(100)          // HNSW parameter for index building\n    .hnswEfRuntime(50)                // HNSW parameter for search\n    .defaultRangeThreshold(0.8)       // Default radius for range searches\n    .textScorer(TextScorer.BM25)      // Text scoring algorithm\n    .inOrder(true)                    // Match terms in order\n    .stopwords(Set.of(\"the\", \"and\"))  // Stopwords to ignore\n    .metadataFields(                  // Metadata field definitions\n        MetadataField.tag(\"category\"),\n        MetadataField.numeric(\"year\"),\n        MetadataField.text(\"description\")\n    )\n    .initializeSchema(true)           // Auto-create index schema\n    .build();\n```\n\n## Distance Metrics\n\nThe Redis Vector Store supports three distance metrics:\n\n- **COSINE**: Cosine similarity (default)\n- **L2**: Euclidean distance\n- **IP**: Inner Product\n\nEach metric is automatically normalized to a 0-1 similarity score, where 1 is most similar.\n\n## Text Scoring Algorithms\n\nFor text search, several scoring algorithms are supported:\n\n- **BM25**: Modern version of TF-IDF with term saturation (default)\n- **TFIDF**: Classic term frequency-inverse document frequency\n- **BM25STD**: Standardized BM25\n- **DISMAX**: Disjunction max\n- **DOCSCORE**: Document score\n\nScores are normalized to a 0-1 range for consistency with vector similarity scores."
