We welcome pull requests, but ask that you carefully read this document first to understand how best to submit them; what kind of changes are likely to be accepted; and what to expect from the Spring team when evaluating your submission. Please refer back to this document as a checklist before issuing any pull request; this will save time for everyone! == Code of Conduct This project adheres to the Contributor Covenant https://github.com/spring-projects/spring-ai#coc-ov-file[code of conduct]. By participating, you are expected to uphold this code. Please report unacceptable behavior to spring-code-of-conduct@pivotal.io. == Understand the basics Not sure what a *pull request* is, or how to submit one? Take a look at GitHub's excellent documentation: https://help.github.com/articles/using-pull-requests/[Using Pull Requests] first. == Search GitHub ticket first; create an issue if necessary Is there already an issue that addresses your concern? Search the https://github.com/spring-projects/spring-ai/issues[GitHub issue tracker] to see if you can find something similar. If not, please create a new issue before submitting a pull request unless the change is truly trivial, e.g. typo fixes, removing compiler warnings, etc. == Developer Certificate of Origin All 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. For 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]. == Fork the Repository 1. Go to https://github.com/spring-projects/spring-ai[https://github.com/spring-projects/spring-ai] 2. Hit the "fork" button and choose your own GitHub account as the target 3. For more detail see https://help.github.com/articles/fork-a-repo/[Fork A Repo]. == Setup your Local Development Environment 1. `git clone --recursive git@github.com:/spring-ai.git` 2. `cd spring-ai` 3. `git remote show` _you should see only 'origin' - which is the fork you created for your own GitHub account_ 4. `git remote add upstream git@github.com:spring-projects/spring-ai.git` 5. `git remote show` _you should now see 'upstream' in addition to 'origin' where 'upstream' is the SpringIO repository from which releases are built_ 6. `git fetch --all` 7. `git branch -a` _you should see branches on origin as well as upstream, including 'main'_ == A Day in the Life of a Contributor * _Always_ work on topic branches (Typically use the GitHub issue ID as the branch name). - For example, to create and switch to a new branch for issue GH-123: `git checkout -b GH-123` * 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). * Please follow the "Commit Guidelines" described in https://git-scm.com/book/ms/v2/Distributed-Git-Contributing-to-a-Project[this chapter of Pro Git]. * Then to begin working on another issue (say GH-101): `git checkout GH-101`. The _-b_ flag is not needed if that branch already exists in your local repository. * When ready to resolve an issue or to collaborate with others, you can push your branch to origin (your fork), e.g.: `git push origin GH-123` * If you want to collaborate with another contributor, have them fork your repository (add it as a remote) and `git fetch ` to grab your branch. Alternatively, they can use `git fetch --all` to sync their local state with all of their remotes. * If you grant that collaborator push access to your repository, they can even apply their changes to your branch. * When ready for your contribution to be reviewed for potential inclusion in the main branch of the canonical spring-ai repository (what you know as 'upstream'), issue a pull request to the SpringSource repository (for more detail, see https://help.github.com/articles/using-pull-requests/[Using pull requests]). * The project lead may merge your changes into the upstream main branch as-is, he may keep the pull request open yet add a comment about something that should be modified, or he might reject the pull request by closing it. * A prerequisite for any pull request is that it will be cleanly merge-able with the upstream main's current state. **This is the responsibility of any contributor.** If your pull request cannot be applied cleanly, the project lead will most likely add a comment requesting that you make it merge-able. For a full explanation, see https://git-scm.com/book/en/Git-Branching-Rebasing[the Pro Git section on rebasing]. As stated there: _"> Often, you’ll do this to make sure your commits apply cleanly on a remote branch — perhaps in a project to which you’re trying to contribute but that you don’t maintain."_ == Keeping your Local Code in Sync * As mentioned above, you should always work on topic branches (since 'main' is a moving target). However, you do want to always keep your own 'origin' main branch in sync with the 'upstream' main. * Within your local working directory, you can sync up all remotes' branches with: `git fetch --all` * While on your own local main branch: `git pull upstream main` (which is the equivalent of fetching upstream/main and merging that into the branch you are in currently) * Now that you're in sync, switch to the topic branch where you plan to work, e.g.: `git checkout -b GH-123` * When you get to a stopping point: `git commit` * If changes have occurred on the upstream/main while you were working you can sync again: - Switch back to main: `git checkout main` - Then: `git pull upstream main` - Switch back to the topic branch: `git checkout GH-123` (no -b needed since the branch already exists) - Rebase the topic branch to minimize the distance between it and your recently synced main branch: `git rebase main` (Again, for more detail see https://git-scm.com/book/en/Git-Branching-Rebasing[the Pro Git section on rebasing]). * **Note** You cannot rebase if you have already pushed your branch to your remote because you'd be rewriting history (see **'The Perils of Rebasing'** in the article). If you rebase by mistake, you can undo it as discussed https://stackoverflow.com/questions/134882/undoing-a-git-rebase[in this StackOverflow discussion]. Once you have published your branch, you need to merge in the main rather than rebasing. * Now, if you issue a pull request, it is much more likely to be merged without conflicts. Most likely, any pull request that would produce conflicts will be deferred until the issuer of that pull request makes these adjustments. * Assuming your pull request is merged into the 'upstream' main, you will actually end up pulling that change into your own main eventually, and at that time, you may decide to delete the topic branch from your local repository and your fork (origin) if you pushed it there. - to delete the local branch: `git branch -d GH-123` - to delete the branch from your origin: `git push origin :GH-123` == Maintain a linear commit history When merging to main, the project __always__ uses fast-forward merges. When issuing pull requests, please ensure that your commit history is linear. From the command line you can check this using: ---- git log --graph --pretty=oneline ---- As this may cause lots of typing, we recommend creating a global alias, e.g. `git logg` for this: ---- git config --global alias.logg 'log --graph --pretty=oneline' ---- This command, will provide the following output, which in this case shows a nice linear history: ---- * c129a02e6c752b49bacd4a445092a44f66c2a1e9 INT-2721 Increase Timers on JDBC Delayer Tests * 14e556ce23d49229c420632cef608630b1d82e7d INT-2620 Fix Debug Log * 6140aa7b2cfb6ae309c55a157e94b44e5d0bea4f INT-3037 Fix JDBC MS Discard After Completion * 077f2b24ea871a3937c513e08241d1c6cb9c9179 Update Spring Social Twitter to 1.0.5 * 6d4f2b46d859c903881a561c35aa28df68f8faf3 INT-3053 Allow task-executor on * 56f9581b85a8a40bbcf2461ffc0753212669a68d Update Spring Social Twitter version to 1.0.4 ---- If you see intersecting lines, that usually means that you forgot to rebase you branch. As mentioned earlier, **please rebase against main** before issuing a pull request. == Run Formatting Checks and Make Sure the Build Passes Before 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 automatically adhere to the conventions used in the project (see below). Be sure to commit those reformats before opening a PR if that happens. [source,shell] ---- ./mvnw package ---- === Source Code Style Spring AI source code checkstyle tries to follow the checkstyle guidelines used by the core Spring Framework project with some exceptions. The wiki pages https://github.com/spring-projects/spring-framework/wiki/Code-Style[Code Style] and https://github.com/spring-projects/spring-framework/wiki/IntelliJ-IDEA-Editor-Settings[IntelliJ IDEA Editor Settings] define the source file coding standards we use along with some IDEA editor settings we customize. == Mind the whitespace Please carefully follow the whitespace and formatting conventions already present in the framework. 1. Tabs, not spaces 2. Unix (LF), not DOS (CRLF) line endings 3. Eliminate all trailing whitespace 4. Wrap Javadoc at 90 characters 5. Aim to wrap code at 120 characters, but favor readability over wrapping 6. Preserve existing formatting; i.e. do not reformat code for its own sake 7. Search the codebase using `git grep` and other tools to discover common naming conventions, etc. 8. Latin-1 (ISO-8859-1) encoding for Java sources; use `native2ascii` to convert if necessary == Add Apache license header to all new classes [source, java] ---- /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * https://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ package ...; ---- == Use @since tags Use @since tags for newly-added public API types and methods e.g. [source java] ---- /** * ... * * @author First Last * @since 3.0 * @see ... */ ---- == Submit JUnit test cases for all behavior changes Search the codebase to find related unit tests and add additional @Test methods within. It is also acceptable to submit test cases on a per GitHub issue basis. == Squash commits Use `git rebase --interactive`, `git add --patch` and other tools to "squash" multiple commits into atomic changes. In addition to the man pages for git, there are many resources online to help you understand how these tools work. == Use your real name in git commits Please configure git to use your real first and last name for any commits you intend to submit as pull requests. For example, this is not acceptable: Author: Nickname Rather, please include your first and last name, properly capitalized, as submitted against the SpringSource contributor license agreement: Author: First Last This helps ensure traceability against the CLA, and also goes a long way to ensuring useful output from tools like `git shortlog` and others. You can configure this globally via the account admin area GitHub (useful for fork-and-edit cases); globally with git config --global user.name "First Last" git config --global user.email user@mail.com or locally for the *spring-ai* repository only by omitting the '--global' flag: cd spring-ai git config user.name "First Last" git config user.email user@mail.com == Run all tests prior to submission Make sure that all tests pass prior to submitting your pull request. Again, CI will run the equivalent of the following command on your PR. Make sure that it passes locally before opening your PR: [source,shell] ---- ./mvnw package ---- == Mention your pull request on the associated GitHub issue Add a comment to the associated GitHub issue(s) linking to your new pull request. == Provide a Link to the GitHub issue in the Associated Pull Request There are multiple ways to link a Pull Request to a GitHub issue as described https://help.github.com/en/github/managing-your-work-on-github/linking-a-pull-request-to-an-issue[here]. One way would be to add a GitHub issue link to your first commit comment of the pull request on the second line, so your commit message may look like this: ---- GH-1: Add Contribution Guidelines Fixes GH-1 (https://github.com/spring-projects/spring-ai/issues/1) * add `CONTRIBUTING.adoc` describing the Contribution procedure * mention Contribution Guidelines in the `README.md` * mention CODE_OF_CONDUCT in the `README.md` ---- Also by using specific https://help.github.com/en/github/managing-your-work-on-github/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword[keywords] you can link to a GitHub issue like so: Closes #10 ================================================ FILE: LICENSE.txt ================================================ Apache License Version 2.0, January 2004 https://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.

Its goal is to apply to the AI domain Spring ecosystem design principles such as portability and modular design and promote using POJOs as the building blocks of an application to the AI domain. ![spring-ai-integration-diagram-3](https://docs.spring.io/spring-ai/reference/_images/spring-ai-integration-diagram-3.svg) > At its core, Spring AI addresses the fundamental challenge of AI integration: Connecting your enterprise __Data__ and __APIs__ with the __AI Models__. The project draws inspiration from notable Python projects, such as [LangChain](https://docs.langchain.com/docs/) and [LlamaIndex](https://gpt-index.readthedocs.io/en/latest/getting_started/concepts.html), 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. You can check out the blog post [Why Spring AI](https://spring.io/blog/2024/11/19/why-spring-ai) for additional motivations. This is a high level feature overview. You can find more details in the [Reference Documentation](https://docs.spring.io/spring-ai/reference/) * 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: - [Chat Completion](https://docs.spring.io/spring-ai/reference/api/chatmodel.html) - [Embedding](https://docs.spring.io/spring-ai/reference/api/embeddings.html) - [Text to Image](https://docs.spring.io/spring-ai/reference/api/imageclient.html) - [Audio Transcription](https://docs.spring.io/spring-ai/reference/api/audio/transcriptions.html) - [Text to Speech](https://docs.spring.io/spring-ai/reference/api/audio/speech.html) - [Moderation](https://docs.spring.io/spring-ai/reference/api/index.html#api/moderation) - **Latest Models**: GPT-5, and other cutting-edge models for advanced AI applications. * 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. * [Structured Outputs](https://docs.spring.io/spring-ai/reference/api/structured-output-converter.html) - Mapping of AI Model output to POJOs. * 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*. * 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). * [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. * [Observability](https://docs.spring.io/spring-ai/reference/observability/index.html) - Provides insights into AI-related operations. * Document injection [ETL framework](https://docs.spring.io/spring-ai/reference/api/etl-pipeline.html) for Data Engineering. * [AI Model Evaluation](https://docs.spring.io/spring-ai/reference/api/testing.html) - Utilities to help evaluate generated content and protect against hallucinated response. * [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. * [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. * 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). * 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. ## Getting Started Please refer to the [Getting Started Guide](https://docs.spring.io/spring-ai/reference/getting-started.html) for instruction on adding your dependencies. ## Project Resources * [Documentation](https://docs.spring.io/spring-ai/reference/) * [Issues](https://github.com/spring-projects/spring-ai/issues) * [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 * [Spring AI Examples](https://github.com/spring-projects/spring-ai-examples) contains example projects that explain specific features in more detail. * [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. ## Breaking changes * 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. ## Cloning the repo This 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). To clone it you have to either: - 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`. - Or install the [Git Large File Storage](https://git-lfs.com/) before cloning the repo. ## Building The project targets and build artifacts compatible with Java 17+, but requires JDK 21 to build. This is enforced by the maven enforcer plugin. To build with running unit tests ```shell ./mvnw clean package ``` To build including integration tests. ```shell ./mvnw clean verify -Pintegration-tests ``` Note 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. To 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. ```shell ./mvnw -pl vector-stores/spring-ai-pgvector-store -am -Pintegration-tests -Dfailsafe.failIfNoSpecifiedTests=false -Dfailsafe.rerunFailingTestsCount=2 -Dit.test=PgVectorStoreIT verify ``` ### Integration Tests There are many integration tests, so it often isn't realistic to run them all at once. A quick pass through the most important pathways that runs integration tests for * OpenAI models * OpenAI autoconfiguration * PGVector * Chroma can be done with the profile `-Pci-fast-integration-tests` and is used in the main CI build of this project. A full integration test is done twice a day in the [Spring AI Integration Test Repository](https://github.com/spring-projects/spring-ai-integration-tests) One way to run integration tests on part of the code is to first do a quick compile and install of the project ```shell ./mvnw clean install -DskipTests -Dmaven.javadoc.skip=true ``` Then run the integration test for a specific module using the `-pl` option ```shell ./mvnw verify -Pintegration-tests -pl spring-ai-spring-boot-testcontainers ``` ### Documentation To build the docs ```shell ./mvnw -pl spring-ai-docs antora ``` The docs are then in the directory `spring-ai-docs/target/antora/site/index.html` ### Formatting the Source Code The code is formatted using the [java-format plugin](https://github.com/spring-io/spring-javaformat) as part of the build. Correct formatting is enforced by CI. ### Updating License Headers To update the year on license headers using the [license-maven-plugin](https://oss.carbou.me/license-maven-plugin/#goals) ```shell ./mvnw license:update-file-header -Plicense ``` ### Javadocs To check javadocs using the [javadoc:javadoc](https://maven.apache.org/plugins/maven-javadoc-plugin/) ```shell ./mvnw javadoc:javadoc ``` #### Source Code Style Spring AI source code checkstyle tries to follow the checkstyle guidelines used by the core Spring Framework project with some exceptions. The wiki pages [Code Style](https://github.com/spring-projects/spring-framework/wiki/Code-Style) and [IntelliJ IDEA Editor Settings](https://github.com/spring-projects/spring-framework/wiki/IntelliJ-IDEA-Editor-Settings) define the source file coding standards we use along with some IDEA editor settings we customize. Run checkstyle manually: ```shell ./mvnw process-sources -P checkstyle-check ``` ## Contributing Your contributions are always welcome!

* This configuration class sets up the necessary beans for MCP client functionality, * including both synchronous and asynchronous clients along with their respective tool * callbacks. It is automatically enabled when the required classes are present on the * classpath and can be explicitly disabled through properties. * *

* Configuration Properties: *

    *
  • {@code spring.ai.mcp.client.enabled} - Enable/disable MCP client support (default: * true) *
  • {@code spring.ai.mcp.client.type} - Client type: SYNC or ASYNC (default: SYNC) *
  • {@code spring.ai.mcp.client.name} - Client implementation name *
  • {@code spring.ai.mcp.client.version} - Client implementation version *
  • {@code spring.ai.mcp.client.request-timeout} - Request timeout duration *
  • {@code spring.ai.mcp.client.initialized} - Whether to initialize clients on * creation *
* *

* The configuration is activated after the transport-specific auto-configurations (Stdio, * SSE HTTP, and SSE WebFlux) to ensure proper initialization order. At least one * transport must be available for the clients to be created. * *

* Key features: *

    *
  • Synchronous and Asynchronous Client Support: *
      *
    • Creates and configures MCP clients based on available transports *
    • Supports both blocking (sync) and non-blocking (async) operations *
    • Automatic client initialization if enabled *
    *
  • Integration Support: *
      *
    • Sets up tool callbacks for Spring AI integration *
    • Supports multiple named transports *
    • Proper lifecycle management with automatic cleanup *
    *
  • Customization Options: *
      *
    • Extensible through {@link McpClientCustomizer} and * {@link McpClientCustomizer} *
    • Configurable timeouts and client information *
    • Support for custom transport implementations *

* This test class validates that the Spring Boot auto-configuration for MCP clients works * correctly, including bean creation, property binding, and customization support. The * tests focus on verifying that the auto-configuration creates the expected beans without * requiring actual MCP protocol communication. * *

Key Testing Patterns:

*
    *
  • Mock Transport Configuration: Uses properly configured Mockito * mocks for {@code McpClientTransport} that handle default interface methods like * {@code protocolVersions()}, {@code connect()}, and {@code sendMessage()}
    • * *
  • Initialization Prevention: Most tests use * {@code spring.ai.mcp.client.initialized=false} to prevent the auto-configuration from * calling {@code client.initialize()} explicitly, which would cause 20-second timeouts * waiting for real MCP protocol communication
    • * *
  • Bean Creation Testing: Tests verify that the correct beans are * created (e.g., {@code mcpSyncClients}, {@code mcpAsyncClients}) without requiring full * client initialization
    • *
* *

Important Notes:

*
    *
  • When {@code initialized=false} is used, the {@code toolCallbacks} bean is not * created because it depends on fully initialized MCP clients
    • * *
  • The mock transport configuration is critical - Mockito mocks don't inherit default * interface methods, so {@code protocolVersions()}, {@code connect()}, and * {@code sendMessage()} must be explicitly configured
    • * *
  • Tests validate both the auto-configuration behavior and the resulting * {@code McpClientCommonProperties} configuration

* This configuration class sets up the WebFlux-specific transport components for the MCP * server, providing reactive Server-Sent Events (SSE) communication through Spring * WebFlux. It is activated when: *

    *
  • The WebFluxSseServerTransportProvider class is on the classpath (from * mcp-spring-webflux dependency)
    • *
  • Spring WebFlux's RouterFunction class is available (from * spring-boot-starter-webflux)
    • *
  • The {@code spring.ai.mcp.server.transport} property is set to {@code WEBFLUX}
    • *
*

* The configuration provides: *

    *
  • A WebFluxSseServerTransportProvider bean for handling reactive SSE * communication
    • *
  • A RouterFunction bean that sets up the reactive SSE endpoint

* This configuration class sets up the WebMvc-specific transport components for the MCP * server, providing Server-Sent Events (SSE) communication through Spring MVC. It is * activated when: *

    *
  • The WebMvcSseServerTransport class is on the classpath (from mcp-spring-webmvc * dependency)
    • *
  • Spring MVC's RouterFunction class is available (from spring-boot-starter-web)
    • *
  • The {@code spring.ai.mcp.server.transport} property is set to {@code WEBMVC}
    • *
*

* The configuration provides: *

    *
  • A WebMvcSseServerTransport bean for handling SSE communication
    • *
  • A RouterFunction bean that sets up the SSE endpoint
    • *
*

* Required dependencies: 

{@code
 * 
 *     org.springframework.boot

The starters are designed to be used independently or together based on your requirements. ## Key Changes ### 1. Property Namespace Changes Old properties: ```properties spring.ai.vertex.ai.gemini.project-id=my-project spring.ai.vertex.ai.gemini.location=us-central1 spring.ai.vertex.ai.gemini.chat.options.model=gemini-pro spring.ai.vertex.ai.embedding.text.options.model=textembedding-gecko ``` New properties: ```properties # For Vertex AI mode spring.ai.google.genai.project-id=my-project spring.ai.google.genai.location=us-central1 spring.ai.google.genai.chat.options.model=gemini-2.0-flash # For Gemini Developer API mode (new!) spring.ai.google.genai.api-key=your-api-key spring.ai.google.genai.chat.options.model=gemini-2.0-flash # Embedding properties spring.ai.google.genai.embedding.project-id=my-project spring.ai.google.genai.embedding.location=us-central1 spring.ai.google.genai.embedding.text.options.model=text-embedding-004 ``` ### 2. New Authentication Options The new SDK supports both: - **Vertex AI mode**: Using Google Cloud credentials (same as before) - **Gemini Developer API mode**: Using API keys (new!) ### 3. Removed Features - `transport` property is no longer needed - Multimodal embedding autoconfiguration has been removed (pending support in new SDK) ### 4. Bean Name Changes If you were autowiring beans by name: - `vertexAi` → `googleGenAiClient` - `vertexAiGeminiChat` → `googleGenAiChatModel` - `textEmbedding` → `googleGenAiTextEmbedding` ### 5. Class Changes If you were importing classes directly: - `com.google.cloud.vertexai.VertexAI` → `com.google.genai.Client` - `org.springframework.ai.vertexai.gemini.*` → `org.springframework.ai.google.genai.*` ## Migration Steps 1. Update your application properties: - Replace `spring.ai.vertex.ai.*` with `spring.ai.google.genai.*` - Remove any `transport` configuration 2. If using API key authentication: - Set `spring.ai.google.genai.api-key` property - Remove project-id and location for chat (not needed with API key) 3. Update any custom configurations or bean references 4. Test your application thoroughly ## Environment Variables ```bash export GOOGLE_CLOUD_PROJECT=my-project export GOOGLE_CLOUD_LOCATION=us-central1 ``` New (additional option): ```bash export GOOGLE_API_KEY=your-api-key ``` ## Backward Compatibility The old autoconfiguration module is still available but deprecated. We recommend migrating to the new module as soon as possible. ================================================ FILE: auto-configurations/models/spring-ai-autoconfigure-model-google-genai/pom.xml ================================================ 4.0.0 org.springframework.ai spring-ai-parent 2.0.0-SNAPSHOT ../../../pom.xml spring-ai-autoconfigure-model-google-genai jar Spring AI Google GenAI Auto Configuration Spring AI Google GenAI Auto Configuration https://github.com/spring-projects/spring-ai https://github.com/spring-projects/spring-ai scm:git:git://github.com/spring-projects/spring-ai.git scm:git:ssh://git@github.com/spring-projects/spring-ai.git org.springframework.ai spring-ai-google-genai-embedding ${project.parent.version} true org.springframework.ai spring-ai-google-genai ${project.parent.version} true org.springframework.ai spring-ai-autoconfigure-model-tool ${project.parent.version} org.springframework.ai spring-ai-autoconfigure-retry ${project.parent.version} org.springframework.ai spring-ai-autoconfigure-model-chat-observation ${project.parent.version} org.springframework.ai spring-ai-autoconfigure-model-embedding-observation ${project.parent.version} org.springframework.boot spring-boot-starter true org.springframework.boot spring-boot-starter-restclient true org.springframework.boot spring-boot-configuration-processor true org.springframework.boot spring-boot-autoconfigure-processor true org.springframework.ai spring-ai-test ${project.parent.version} test org.springframework.boot spring-boot-starter-test test org.mockito mockito-core test org.testcontainers testcontainers-junit-jupiter test org.testcontainers testcontainers-ollama test ================================================ FILE: auto-configurations/models/spring-ai-autoconfigure-model-google-genai/src/main/java/org/springframework/ai/model/google/genai/autoconfigure/chat/CachedContentServiceCondition.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License");

It can be seen as a TL,DR version of this https://docs.spring.io/spring-framework/reference/core/null-safety.html[Spring reference]. Some 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. == Problems The "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. == Solution Spring AI uses https://github.com/spring-projects/spring-ai/blob/a8d11421c9605c2eef609535448a94c5104960ed/pom.xml#L470-L531[JSpecify + NullAway + ErrorProne] to enforce nullability checks. For 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). Any new package should be annotated with `@NullMarked`, like so: [source,java] ---- import org.jspecify.annotations.NullMarked; @NullMarked package org.springframework.ai.foo; ---- From there on, any element in that package assumes non-null type usage by default (for its own members). NOTE: 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. Annotating 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: [source, java] ---- import org.springframework.util.Assert; // in a @NullMarked package public class MyThing { // bar and foo are assumed to be non-null public MyThing(String bar, Foo foo) { Assert.notNull(bar, "bar should not be null"); Assert.notNull(foo, "foo should not be null"); this.bar = bar; this.foo = foo; ... } } ---- NOTE: `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")`. When a value _could_ be `null`, annotate it with `@Nullable`. This applies to parameters, fields and even generic components (see below). [source, java] ---- import org.springframework.util.Assert; import org.jspecify.annotations.Nullable; // in a @NullMarked package public class MyThing { // bar and foo are assumed to be non-null public MyThing(@Nullable String bar, Foo foo) { Assert.notNull(foo, "foo should not be null"); this.bar = bar; this.foo = foo; ... } } ---- As 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`. It 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 [source, java] ---- // in a @NullMarked package public class MyThing { private @Nullable Foo foo; } ---- and not [source, java] ---- // in a @NullMarked package public class MyThing { @Nullable private Foo foo; } ---- Similarly, for method return types, use [source, java] ---- // in a @NullMarked package public class MyThing { public @Nullable Foo something() { ... return null; } } ---- and not [source, java] ---- // in a @NullMarked package public class MyThing { @Nullable public Foo something() { ... return null; } } ---- As a rule of thumb, the annotation should be placed closest to the thing it expresses the nullability of: * `java.util.Map.@Nullable Entry` renders the _entry_ nullable (not the map), * `@Nullable String[]` is a (non-null) array of nullable Strings, * `String @Nullable []` is a nullable array of (non-null) Strings, * _etc._ === Nullability and API design considerations It 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 * initialize collections and arrays to empty structures instead of `null`. This allows iteration without having to think whether to handle `null` or not, * 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. === Nullability and `@ConfigurationProperties` Spring Boot `@ConfigurationProperties` classes should be annotated using the following rationale, given that Boot will never inject a `null` value as a property: * 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), * 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. === Nullability and the Builder pattern TODO === User Impact Checks are only performed in scopes that are annotated as `@NullMarked`. What 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. === FAQ For further reference, please consult the following: * JSpecify https://jspecify.dev/docs/user-guide/[user-guide] * 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 * https://github.com/uber/NullAway[NullAway] and https://errorprone.info/[ErrorProne] ================================================ FILE: document-readers/jsoup-reader/ README.md ================================================ # Spring AI JSoup Document Reader This module provides an HTML document reader for the Spring AI project. It leverages the [JSoup](https://jsoup.org/) library to parse HTML content and extract text and metadata, making it suitable for use in AI applications. ## Features * **Flexible Text Extraction:** * Extract all text from the `` of an HTML document. * Extract text from specific elements using CSS selectors. * Group text by element, creating a separate document for each selected element. * Combine text from multiple selected elements using a configurable separator. * **Metadata Extraction:** * Extract the document title. * Extract content from `` tags (e.g., description, keywords). You can specify which meta tags to extract. * Extract a list of all absolute URLs of links (``) within the document. * **Configurable:** * Specify the character encoding (defaults to UTF-8). * Customize the CSS selector for element selection. * Configure the separator string for joining text from multiple elements. * Choose whether to extract all text or use element-based extraction. * Enable/disable link URL extraction. * Add additional metadata using configuration. * **Resource-Based:** Works with Spring's `Resource` abstraction, allowing you to read HTML from files, classpath resources, URLs, and even in-memory byte arrays. --- #### How to Build: ```bash ./mvnw -pl document-readers/jsoup-reader clean install ``` ================================================ FILE: document-readers/jsoup-reader/pom.xml ================================================ 4.0.0 org.springframework.ai spring-ai-parent 2.0.0-SNAPSHOT ../../pom.xml spring-ai-jsoup-document-reader jar Spring AI Document Reader - HTML Spring AI HTML document reader https://github.com/spring-projects/spring-ai https://github.com/spring-projects/spring-ai scm:git:git://github.com/spring-projects/spring-ai.git scm:git:ssh://git@github.com/spring-projects/spring-ai.git org.springframework.ai spring-ai-commons ${project.parent.version} org.jsoup jsoup ${jsoup.version} org.springframework.boot spring-boot-starter-test test ================================================ FILE: document-readers/jsoup-reader/src/main/java/org/springframework/ai/reader/jsoup/JsoupDocumentReader.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * https://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ package org.springframework.ai.reader.jsoup; import java.io.IOException; import java.io.InputStream; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import java.util.stream.Collectors; import org.jsoup.Jsoup; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; import org.springframework.ai.document.Document; import org.springframework.ai.document.DocumentReader; import org.springframework.ai.reader.jsoup.config.JsoupDocumentReaderConfig; import org.springframework.core.io.DefaultResourceLoader; import org.springframework.core.io.Resource; /** * Reads HTML documents and extracts text content using JSoup. * * This reader provides options for selecting specific HTML elements to extract, handling * links, and extracting metadata.

* Key features: *

    *
  • Implements the {@link McpServerTransportProvider} interface that allows managing * {@link McpServerSession} instances and enabling their communication with the * {@link McpServerTransport} abstraction.
    • *
  • Uses WebFlux for non-blocking request handling and SSE support
    • *
  • Maintains client sessions for reliable message delivery
    • *
  • Supports graceful shutdown with session cleanup
    • *
  • Thread-safe message broadcasting to multiple clients
    • *
* *

* The transport sets up two main endpoints: *

    *
  • SSE endpoint (/sse) - For establishing SSE connections with clients
    • *
  • Message endpoint (configurable) - For receiving JSON-RPC messages from clients
    • *
* *

* This implementation is thread-safe and can handle multiple concurrent client * connections.

It tests various * combinations of client types and server transport mechanisms (stateless, streamable, * SSE) to ensure proper context handling across different configurations. * *

Context Propagation Flow

*
    *
  1. Client sets a value in its transport context via thread-local Reactor context
    2. *
  2. Client-side context provider extracts the value and adds it as an HTTP header to * the request
    3. *
  3. Server-side context extractor reads the header from the incoming request
    4. *
  4. Server handler receives the extracted context and returns the value as the tool * call result
    5. *
  5. Test verifies the round-trip context propagation was successful
    6. *

/** * Integration tests for {@link McpTransportContext} propagation between MCP client and * server using synchronous operations in a Spring WebFlux environment. *

* This test class validates the end-to-end flow of transport context propagation across * different WebFlux-based MCP transport implementations * *

* The test scenario follows these steps: *

    *
  1. The client stores a value in a thread-local variable
    2. *
  2. The client's transport context provider reads this value and includes it in the MCP * context
    3. *
  3. A WebClient filter extracts the context value and adds it as an HTTP header * (x-test)
    4. *
  4. The server's {@link McpTransportContextExtractor} reads the header from the * request
    5. *
  5. The server returns the header value as the tool call result, validating the * round-trip
    6. *
* *

* This test demonstrates how custom context can be propagated through HTTP headers in a * reactive WebFlux environment, enabling features like authentication tokens, correlation * IDs, or other metadata to flow between MCP client and server. * * @author Daniel Garnier-Moiroux * @author Christian Tzolov * @since 1.0.0 * @see McpTransportContext * @see McpTransportContextExtractor * @see WebFluxStatelessServerTransport * @see WebFluxStreamableServerTransportProvider * @see WebFluxSseServerTransportProvider */ @Timeout(15) public class SyncServerMcpTransportContextIT { private static final ThreadLocal CLIENT_SIDE_HEADER_VALUE_HOLDER = new ThreadLocal<>(); private static final String HEADER_NAME = "x-test"; private final Supplier clientContextProvider = () -> { var headerValue = CLIENT_SIDE_HEADER_VALUE_HOLDER.get(); return headerValue != null ?

* Key features: *

    *
  • Implements bidirectional communication using HTTP POST for client-to-server * messages and SSE for server-to-client messages
    • *
  • Manages client sessions with unique IDs for reliable message delivery
    • *
  • Supports graceful shutdown with proper session cleanup
    • *
  • Provides JSON-RPC message handling through configured endpoints
    • *
  • Includes built-in error handling and logging
    • *
* *

* The transport operates on two main endpoints: *

    *
  • {@code /sse} - The SSE endpoint where clients establish their event stream * connection
    • *
  • A configurable message endpoint where clients send their JSON-RPC messages via HTTP * POST
    • *
* *

* This implementation uses {@link ConcurrentHashMap} to safely manage multiple client * sessions in a thread-safe manner.

They have been moved into the Spring AI project itself. This is a breaking change that requires dependency and import updates in every application that directly references these transport classes. --- ## Breaking Changes ### 1. Maven Dependency Group ID Change The `mcp-spring-webflux` and `mcp-spring-webmvc` artifacts have moved from the `io.modelcontextprotocol.sdk` group to `org.springframework.ai`. #### Before (MCP Java SDK < 1.0.x & Spring AI < 2.0.x) ```xml io.modelcontextprotocol.sdk mcp-spring-webflux io.modelcontextprotocol.sdk mcp-spring-webmvc ``` #### After (MCP Java SDK ≥ 1.0.x & Spring AI ≥ 2.0.x) ```xml org.springframework.ai mcp-spring-webflux org.springframework.ai mcp-spring-webmvc ``` > **Note:** 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. --- ### 2. Java Package Relocation All transport classes have been moved to `org.springframework.ai` packages. #### Server Transports | Class | Old package (MCP SDK) | New package (Spring AI) | |---|---|---| | `WebFluxSseServerTransportProvider` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webflux.transport` | | `WebFluxStreamableServerTransportProvider` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webflux.transport` | | `WebFluxStatelessServerTransport` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webflux.transport` | | `WebMvcSseServerTransportProvider` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webmvc.transport` | | `WebMvcStreamableServerTransportProvider` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webmvc.transport` | | `WebMvcStatelessServerTransport` | `io.modelcontextprotocol.server.transport` | `org.springframework.ai.mcp.server.webmvc.transport` | #### Client Transports | Class | Old package (MCP SDK) | New package (Spring AI) | |---|---|---| | `WebFluxSseClientTransport` | `io.modelcontextprotocol.client.transport` | `org.springframework.ai.mcp.client.webflux.transport` | | `WebClientStreamableHttpTransport` | `io.modelcontextprotocol.client.transport` | `org.springframework.ai.mcp.client.webflux.transport` | #### Example — Update Imports ```java // Before import io.modelcontextprotocol.server.transport.WebFluxSseServerTransportProvider; import io.modelcontextprotocol.server.transport.WebMvcSseServerTransportProvider; import io.modelcontextprotocol.client.transport.WebFluxSseClientTransport; import io.modelcontextprotocol.client.transport.WebClientStreamableHttpTransport; // After import org.springframework.ai.mcp.server.webflux.transport.WebFluxSseServerTransportProvider; import org.springframework.ai.mcp.server.webmvc.transport.WebMvcSseServerTransportProvider; import org.springframework.ai.mcp.client.webflux.transport.WebFluxSseClientTransport; import org.springframework.ai.mcp.client.webflux.transport.WebClientStreamableHttpTransport; ``` --- ### 3. MCP SDK Version Requirement Spring 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. --- ## Spring Boot Auto-configuration Users (No Manual Changes Needed) If 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 in [section 1](#1-maven-dependency-group-id-change). --- ================================================ FILE: memory/repository/spring-ai-model-chat-memory-repository-cassandra/pom.xml ================================================ 4.0.0 org.springframework.ai spring-ai-parent 2.0.0-SNAPSHOT ../../../pom.xml spring-ai-model-chat-memory-repository-cassandra Spring AI Apache Cassandra Chat Memory Repository Spring AI Apache Cassandra Chat Memory Repository implementation https://github.com/spring-projects/spring-ai https://github.com/spring-projects/spring-ai scm:git:git://github.com/spring-projects/spring-ai.git scm:git:ssh://git@github.com/spring-projects/spring-ai.git org.springframework.ai spring-ai-model ${project.version} org.apache.cassandra java-driver-query-builder org.springframework.boot spring-boot-starter-test test org.springframework.ai spring-ai-test ${project.version} test org.springframework.boot spring-boot-testcontainers test org.testcontainers testcontainers-cassandra test org.testcontainers testcontainers-junit-jupiter test ================================================ FILE: memory/repository/spring-ai-model-chat-memory-repository-cassandra/src/main/java/org/springframework/ai/chat/memory/repository/cassandra/CassandraChatMemoryRepository.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License");

[Anthropic Java SDK GitHub repository](https://github.com/anthropics/anthropic-sdk-java) ## Authentication Configure your Anthropic API key either programmatically or via environment variable: ```java AnthropicChatOptions options = AnthropicChatOptions.builder() .apiKey("") .build(); ``` Or using the environment variable (automatically detected): ```bash export ANTHROPIC_API_KEY= ``` ## Features This module supports: - **Chat Completions** - Synchronous and streaming responses - **Tool Calling** - Function calling with automatic tool execution - **Streaming Tool Calling** - Tool calls in streaming mode with partial JSON accumulation - **Multi-Modal** - Images and PDF documents - **Extended Thinking** - Claude's thinking/reasoning feature with full streaming support - **Citations** - Document-grounded responses with source attribution - **Prompt Caching** - Reduce costs for repeated context with configurable strategies - **Structured Output** - JSON schema-constrained responses with effort control - **Per-Request HTTP Headers** - Custom headers per API call for tracking, beta features, and routing - **Observability** - Micrometer-based metrics and tracing ### Planned Features - **Amazon Bedrock** - Access Claude through AWS Bedrock - **Google Vertex AI** - Access Claude through Google Cloud ## Basic Usage ```java // Create chat model with default options AnthropicChatModel chatModel = new AnthropicChatModel( AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .maxTokens(1024) .build() ); // Synchronous call ChatResponse response = chatModel.call(new Prompt("Hello, Claude!")); // Streaming call Flux stream = chatModel.stream(new Prompt("Tell me a story")); ``` ## Tool Calling ```java var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .toolCallbacks(FunctionToolCallback.builder("getWeather", new WeatherService()) .description("Get the current weather for a location") .inputType(WeatherRequest.class) .build()) .build(); ChatResponse response = chatModel.call(new Prompt("What's the weather in Paris?", options)); ``` ## Extended Thinking Enable Claude's reasoning feature to see step-by-step thinking before the final answer: ```java var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .temperature(1.0) // required when thinking is enabled .maxTokens(16000) .thinkingEnabled(10000L) // budget must be >= 1024 and < maxTokens .build(); ChatResponse response = chatModel.call(new Prompt("Solve this step by step...", options)); ``` Three thinking modes are available via convenience builders: - `thinkingEnabled(budgetTokens)` - Enable with a specific token budget - `thinkingAdaptive()` - Let Claude decide whether to think - `thinkingDisabled()` - Explicitly disable thinking Thinking is fully supported in both synchronous and streaming modes, including signature capture for thinking block verification. ## Citations Anthropic'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. ```java // Create a citation document AnthropicCitationDocument document = AnthropicCitationDocument.builder() .plainText("The Eiffel Tower was completed in 1889 in Paris, France. " + "It stands 330 meters tall and was designed by Gustave Eiffel.") .title("Eiffel Tower Facts") .citationsEnabled(true) .build(); // Call the model with the document ChatResponse response = chatModel.call( new Prompt( "When was the Eiffel Tower built?", AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .maxTokens(1024) .citationDocuments(document) .build() ) ); // Access citations from response metadata List citations = (List) response.getMetadata().get("citations"); for (Citation citation : citations) { System.out.println("Document: " + citation.getDocumentTitle()); System.out.println("Cited text: " + citation.getCitedText()); } ``` PDF and custom content block documents are also supported via `pdfFile()`, `pdf()`, and `customContent()` builders. ## Prompt Caching Prompt caching reduces costs and latency by caching repeated context (system prompts, tool definitions, conversation history) across API calls. Five caching strategies are available: | Strategy | Description | |----------|-------------| | `NONE` | No caching (default) | | `SYSTEM_ONLY` | Cache system message content | | `TOOLS_ONLY` | Cache tool definitions | | `SYSTEM_AND_TOOLS` | Cache both system messages and tool definitions | | `CONVERSATION_HISTORY` | Cache system messages, tools, and conversation messages | ```java // Cache system messages to reduce costs for repeated prompts var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .maxTokens(1024) .cacheOptions(AnthropicCacheOptions.builder() .strategy(AnthropicCacheStrategy.SYSTEM_AND_TOOLS) .build()) .build(); ChatResponse response = chatModel.call( new Prompt(List.of( new SystemMessage("You are an expert assistant with deep domain knowledge..."), new UserMessage("What is the capital of France?")), options)); // Access cache token usage via native SDK usage com.anthropic.models.messages.Usage sdkUsage = (com.anthropic.models.messages.Usage) response.getMetadata().getUsage().getNativeUsage(); long cacheCreation = sdkUsage.cacheCreationInputTokens().orElse(0L); long cacheRead = sdkUsage.cacheReadInputTokens().orElse(0L); ``` You 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: ```java var options = AnthropicCacheOptions.builder() .strategy(AnthropicCacheStrategy.SYSTEM_ONLY) .messageTypeTtl(MessageType.SYSTEM, AnthropicCacheTtl.ONE_HOUR) .messageTypeMinContentLength(MessageType.SYSTEM, 100) .multiBlockSystemCaching(true) .build(); ``` ## Structured Output Structured 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. > **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. ### JSON Schema Output ```java var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .outputSchema(""" { "type": "object", "properties": { "name": {"type": "string"}, "capital": {"type": "string"}, "population": {"type": "integer"} }, "required": ["name", "capital"], "additionalProperties": false } """) .build(); ChatResponse response = chatModel.call(new Prompt("Tell me about France.", options)); // Response text will be valid JSON conforming to the schema ``` ### Effort Control Control how much compute Claude spends on its response. Lower effort means faster, cheaper responses; higher effort means more thorough reasoning. ```java var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .effort(OutputConfig.Effort.LOW) // LOW, MEDIUM, HIGH, or MAX .build(); ``` ### Combined Schema + Effort ```java var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .outputSchema("{\"type\":\"object\",\"properties\":{\"answer\":{\"type\":\"integer\"}},\"required\":[\"answer\"],\"additionalProperties\":false}") .effort(OutputConfig.Effort.HIGH) .build(); ``` ### Direct OutputConfig For full control, use the SDK's `OutputConfig` directly: ```java import com.anthropic.models.messages.OutputConfig; import com.anthropic.models.messages.JsonOutputFormat; import com.anthropic.core.JsonValue; var outputConfig = OutputConfig.builder() .effort(OutputConfig.Effort.HIGH) .format(JsonOutputFormat.builder() .schema(JsonOutputFormat.Schema.builder() .putAdditionalProperty("type", JsonValue.from("object")) .putAdditionalProperty("properties", JsonValue.from(Map.of( "name", Map.of("type", "string")))) .putAdditionalProperty("additionalProperties", JsonValue.from(false)) .build()) .build()) .build(); var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .outputConfig(outputConfig) .build(); ``` ## Per-Request HTTP Headers Add custom HTTP headers to individual API calls. Unlike `customHeaders` (which apply to all requests at the client level), `httpHeaders` are set per request. ```java var options = AnthropicChatOptions.builder() .httpHeaders(Map.of( "X-Request-Id", "req-12345", "X-Custom-Tracking", "my-value")) .build(); ChatResponse response = chatModel.call(new Prompt("Hello", options)); ``` ## Logging Enable SDK logging by setting the environment variable: ```bash export ANTHROPIC_LOG=debug ``` ## Documentation For comprehensive documentation, see: - [Spring AI Anthropic Reference Documentation](https://docs.spring.io/spring-ai/reference/api/chat/anthropic-chat.html) - [Anthropic API Documentation](https://docs.anthropic.com/) - [Anthropic Java SDK Documentation](https://github.com/anthropics/anthropic-sdk-java) ================================================ FILE: models/spring-ai-anthropic/pom.xml ================================================ 4.0.0 org.springframework.ai spring-ai-parent 2.0.0-SNAPSHOT ../../pom.xml spring-ai-anthropic jar Spring AI Model - Anthropic Anthropic models support https://github.com/spring-projects/spring-ai https://github.com/spring-projects/spring-ai scm:git:git://github.com/spring-projects/spring-ai.git scm:git:ssh://git@github.com/spring-projects/spring-ai.git org.springframework.ai spring-ai-model ${project.parent.version} com.anthropic anthropic-java ${anthropic-sdk.version} org.slf4j slf4j-api org.springframework.ai spring-ai-test ${project.version} test org.springframework.boot spring-boot-starter-test test io.micrometer micrometer-observation-test test ================================================ FILE: models/spring-ai-anthropic/src/main/java/org/springframework/ai/anthropic/AbstractAnthropicOptions.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * https://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ package org.springframework.ai.anthropic; import java.net.Proxy; import java.time.Duration; import java.util.HashMap; import java.util.Map; import org.jspecify.annotations.Nullable; /** * Base class for common Anthropic SDK configuration options, extended by * {@link AnthropicChatOptions}. * *

  • Synchronous Client: Used for blocking API calls via * {@link #setupSyncClient}
    • *
  • Asynchronous Client: Used for streaming responses via * {@link #setupAsyncClient}
    • *
* *

* Environment Variable Support: *

    *
  • {@code ANTHROPIC_API_KEY} - Primary API key for authentication
    • *
  • {@code ANTHROPIC_AUTH_TOKEN} - Alternative authentication token
    • *
  • {@code ANTHROPIC_BASE_URL} - Override the default API endpoint
    • *
* *

* Default Configuration: *

    *
  • Timeout: 60 seconds
    • *
  • Max Retries: 2
    • *
  • User-Agent: {@code spring-ai-anthropic-sdk}

* Cache Invalidation: *

    *
  • Changing tools invalidates both cache breakpoints (tools are the prefix)
    • *
  • Changing system prompts only invalidates the system cache (tools remain * cached)
    • *
*

* This provides the most comprehensive caching but uses more cache breakpoints. */ SYSTEM_AND_TOOLS, /** * Cache the entire conversation history up to and including the current user * question. This is ideal for multi-turn conversations where you want to reuse the * conversation context while asking new questions. *

* A cache breakpoint is placed on the last user message in the conversation. This * enables incremental caching where each conversation turn builds on the previous * cached prefix, providing significant cost savings and performance improvements. *

* Use this when: *

    *
  • Building multi-turn conversational applications (chatbots, assistants)
    • *
  • Conversation history is substantial (1024+ tokens)
    • *
  • Users are asking follow-up questions that require context from earlier * messages
    • *
  • You want to reduce latency and costs for ongoing conversations
    • *
*

* Model Compatibility: *

    *
  • Verified: Claude 3.x and Claude 4.x models (all variants)
    • *
  • Note: Amazon Nova models theoretically support conversation * caching, but have not been verified in integration tests
    • *
*

* How it works: *

    *
  1. Identifies the last user message in the conversation
    2. *
  2. Places cache breakpoint as the last content block on that message
    3. *
  3. All messages up to and including the last user message are cached (system, * previous user/assistant turns, and current user question)
    4. *
  4. On the next turn, the cached context is reused and a new cache is created * including the assistant response and new user question
    5. *
*

* Example conversation flow: * * 

	 * Turn 1: "My name is Alice" → Response cached
	 * Turn 2: "I work as a data scientist" → Response cached
	 * Turn 3: "What career advice would you give me?" ← Cache applies here
	 *         (Turns 1-2 are read from cache, Turn 3 question is fresh)
	 *
*

* Cache behavior: *

    *
  • First request: Creates cache (cacheWriteInputTokens > 0)
    • *
  • Subsequent requests: Reads from cache (cacheReadInputTokens > 0)
    • *
  • Cache TTL: 5 minutes (resets on each cache hit)
    • *
  • Minimum content: 1024+ tokens required for caching to activate
    • *

Let me share some detailed thoughts on your situation. Working in data science at a tech company in San Francisco puts you at the forefront of innovation. The combination of machine learning and natural language processing is particularly powerful right now, given the explosion of large language models and transformer-based architectures. San Francisco's tech ecosystem offers unparalleled networking opportunities, access to cutting-edge research, and exposure to world-class engineering talent. The recommendation systems space is especially exciting because it sits at the intersection of multiple disciplines: collaborative filtering, content-based methods, matrix factorization, deep learning, and reinforcement learning from human feedback. Companies like Netflix, Spotify, Amazon, and LinkedIn have published extensively on their recommendation architectures, and the field continues to evolve rapidly. Building production-grade recommendation systems requires not just modeling skills but also expertise in data pipelines, feature engineering, A/B testing frameworks, and real-time serving infrastructure. The ability to measure business impact through metrics like click-through rate, conversion rate, and long-term engagement is equally important. I'd be happy to dive deeper into any of these areas.

================================================ FILE: models/spring-ai-google-genai/README.md ================================================ [Google GenAI Chat](https://docs.spring.io/spring-ai/reference/api/chat/google-genai-chat.html) ### Starter ```xml org.springframework.ai spring-ai-starter-model-google-genai ``` ### Manual config ```xml org.springframework.ai spring-ai-google-genai ``` ### Environment variables ```shell export GOOGLE_GENAI_USE_VERTEXAI=true export GOOGLE_CLOUD_PROJECT='your-project-id' export GOOGLE_CLOUD_LOCATION='your-region' ``` ## Extended Usage Metadata The 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. ### Features #### Thinking Tokens Track reasoning tokens for thinking-enabled models like Gemini 2.0 Flash Thinking: ```java ChatResponse response = chatModel.call(prompt); GoogleGenAiUsage usage = (GoogleGenAiUsage) response.getMetadata().getUsage(); Integer thoughtsTokens = usage.getThoughtsTokenCount(); // Reasoning tokens ``` #### Cached Content Tokens Monitor tokens from cached context to optimize API costs: ```java Integer cachedTokens = usage.getCachedContentTokenCount(); // Cached context tokens ``` #### Tool-Use Tokens Track tokens consumed by function calling and tool use: ```java Integer toolUseTokens = usage.getToolUsePromptTokenCount(); // Tool-use tokens ``` #### Modality Breakdowns Get detailed token counts by modality (text, image, audio, video): ```java List promptDetails = usage.getPromptTokensDetails(); for (GoogleGenAiModalityTokenCount detail : promptDetails) { System.out.println(detail.getModality() + ": " + detail.getTokenCount()); } ``` #### Traffic Type Identify whether requests use Pay-As-You-Go or Provisioned Throughput: ```java GoogleGenAiTrafficType trafficType = usage.getTrafficType(); // Returns: ON_DEMAND, PROVISIONED_THROUGHPUT, or UNKNOWN ``` ### Configuration Control whether to include extended metadata (enabled by default): ```java GoogleGenAiChatOptions options = GoogleGenAiChatOptions.builder() .model("gemini-2.0-flash") .includeExtendedUsageMetadata(true) // Enable extended metadata .build(); ``` ### Complete Example ```java @Component public class ExtendedUsageExample { private final GoogleGenAiChatModel chatModel; public void demonstrateExtendedUsage() { Prompt prompt = new Prompt("Analyze this complex multi-modal request"); ChatResponse response = chatModel.call(prompt); // Cast to GoogleGenAiUsage for extended metadata GoogleGenAiUsage usage = (GoogleGenAiUsage) response.getMetadata().getUsage(); // Basic token counts (standard Usage interface) System.out.println("Prompt tokens: " + usage.getPromptTokens()); System.out.println("Completion tokens: " + usage.getCompletionTokens()); System.out.println("Total tokens: " + usage.getTotalTokens()); // Extended metadata (Google GenAI specific) System.out.println("Thinking tokens: " + usage.getThoughtsTokenCount()); System.out.println("Cached tokens: " + usage.getCachedContentTokenCount()); System.out.println("Tool-use tokens: " + usage.getToolUsePromptTokenCount()); // Modality breakdowns if (usage.getPromptTokensDetails() != null) { usage.getPromptTokensDetails().forEach(detail -> System.out.println(" " + detail.getModality() + ": " + detail.getTokenCount()) ); } // Traffic type System.out.println("Traffic type: " + usage.getTrafficType()); // Access native SDK object for any additional metadata GenerateContentResponseUsageMetadata nativeUsage = (GenerateContentResponseUsageMetadata) usage.getNativeUsage(); } } ``` ### Backward Compatibility The extended usage metadata maintains full backward compatibility with the standard `Usage` interface. Code using the basic interface continues to work without modification: ```java // Works with any Spring AI model Usage usage = response.getMetadata().getUsage(); Long promptTokens = usage.getPromptTokens(); Long completionTokens = usage.getCompletionTokens(); ``` ================================================ FILE: models/spring-ai-google-genai/pom.xml ================================================ 4.0.0 org.springframework.ai spring-ai-parent 2.0.0-SNAPSHOT ../../pom.xml spring-ai-google-genai jar Spring AI Model - Google GenAI Google GenAI Gemini models support https://github.com/spring-projects/spring-ai https://github.com/spring-projects/spring-ai scm:git:git://github.com/spring-projects/spring-ai.git scm:git:ssh://git@github.com/spring-projects/spring-ai.git com.google.genai google-genai ${com.google.genai.version} com.github.victools jsonschema-generator ${jsonschema.version} com.github.victools jsonschema-module-jackson ${jsonschema.version} org.springframework.ai spring-ai-model ${project.parent.version} org.springframework.ai spring-ai-retry ${project.parent.version} org.springframework spring-context-support org.slf4j slf4j-api org.springframework.ai spring-ai-test ${project.version} test io.micrometer micrometer-observation-test test ================================================ FILE: models/spring-ai-google-genai/src/main/java/org/springframework/ai/google/genai/GoogleGenAiChatModel.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License");

This is due to the fact that the Google GenAI SDK currently supports text embeddings only, with multimodal embeddings support pending. ## Starter Dependency ```xml org.springframework.ai spring-ai-starter-model-google-genai-embedding ``` ## Manual Configuration ```xml org.springframework.ai spring-ai-google-genai-embedding ``` ## Authentication Modes The module supports two authentication modes: - **Gemini Developer API**: Use an API key for quick prototyping - **Vertex AI**: Use Google Cloud credentials for production deployments See the [documentation](https://docs.spring.io/spring-ai/reference/api/embeddings/google-genai-embeddings-text.html) for detailed configuration instructions. ================================================ FILE: models/spring-ai-google-genai-embedding/pom.xml ================================================ 4.0.0 org.springframework.ai spring-ai-parent 2.0.0-SNAPSHOT ../../pom.xml spring-ai-google-genai-embedding jar Spring AI Model - Google GenAI Embedding Google GenAI Gemini embedding models support https://github.com/spring-projects/spring-ai https://github.com/spring-projects/spring-ai scm:git:git://github.com/spring-projects/spring-ai.git scm:git:ssh://git@github.com/spring-projects/spring-ai.git com.google.genai google-genai ${com.google.genai.version} org.springframework.ai spring-ai-model ${project.parent.version} org.springframework.ai spring-ai-retry ${project.parent.version} org.springframework spring-context-support org.slf4j slf4j-api io.micrometer micrometer-observation-test test org.springframework.ai spring-ai-test ${project.version} test ================================================ FILE: models/spring-ai-google-genai-embedding/src/main/java/org/springframework/ai/google/genai/GoogleGenAiEmbeddingConnectionDetails.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * https://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ package org.springframework.ai.google.genai; import com.google.genai.Client; import org.springframework.util.Assert; import org.springframework.util.StringUtils; /** * GoogleGenAiEmbeddingConnectionDetails represents the details of a connection to the * embedding service using the new Google Gen AI SDK.

Spring Framework Overview Spring makes it easy to create Java enterprise applications. It provides everything you need to embrace the Java language in an enterprise environment, with support for Groovy and Kotlin as alternative languages on the JVM, and with the flexibility to create many kinds of architectures depending on an application’s needs. As of Spring Framework 5.1, Spring requires JDK 8+ (Java SE 8+) and provides out-of-the-box support for JDK 11 LTS. Java SE 8 update 60 is suggested as the minimum patch release for Java 8, but it is generally recommended to use a recent patch release. Spring supports a wide range of application scenarios. In a large enterprise, applications often exist for a long time and have to run on a JDK and application server whose upgrade cycle is beyond developer control. Others may run as a single jar with the server embedded, possibly in a cloud environment. Yet others may be standalone applications (such as batch or integration workloads) that do not need a server. Spring is open source. It has a large and active community that provides continuous feedback based on a diverse range of real-world use cases. This has helped Spring to successfully evolve over a very long time. 1.1. What We Mean by "Spring" The term "Spring" means different things in different contexts. It can be used to refer to the Spring Framework project itself, which is where it all started. Over time, other Spring projects have been built on top of the Spring Framework. Most often, when people say "Spring", they mean the entire family of projects. This reference documentation focuses on the foundation: the Spring Framework itself. The Spring Framework is divided into modules. Applications can choose which modules they need. At the heart are the modules of the core container, including a configuration model and a dependency injection mechanism. Beyond that, the Spring Framework provides foundational support for different application architectures, including messaging, transactional data and persistence, and web. It also includes the Servlet-based Spring MVC web framework and, in parallel, the Spring WebFlux reactive web framework. A note about modules: Spring’s framework jars allow for deployment to JDK 9’s module path ("Jigsaw"). For use in Jigsaw-enabled applications, the Spring Framework 5 jars come with "Automatic-Module-Name" manifest entries which define stable language-level module names ("spring.core", "spring.context", etc.) independent from jar artifact names (the jars follow the same naming pattern with "-" instead of ".", e.g. "spring-core" and "spring-context"). Of course, Spring’s framework jars keep working fine on the classpath on both JDK 8 and 9+. 1.2. History of Spring and the Spring Framework Spring came into being in 2003 as a response to the complexity of the early J2EE specifications. While some consider Java EE and its modern-day successor Jakarta EE to be in competition with Spring, they are in fact complementary. The Spring programming model does not embrace the Jakarta EE platform specification; rather, it integrates with carefully selected individual specifications from the traditional EE umbrella: • Servlet API (JSR 340) • WebSocket API (JSR 356) • Concurrency Utilities (JSR 236) • JSON Binding API (JSR 367) • Bean Validation (JSR 303) • JPA (JSR 338) • JMS (JSR 914) • as well as JTA/JCA setups for transaction coordination, if necessary. The Spring Framework also supports the Dependency Injection (JSR 330) and Common Annotations (JSR 250) specifications, which application developers may choose to use instead of the Spring- specific mechanisms provided by the Spring Framework. Originally, those were based on common javax packages. As of Spring Framework 6.0, Spring has been upgraded to the Jakarta EE 9 level (e.g. Servlet 5.0+, JPA 3.0+), based on the jakarta namespace instead of the traditional javax packages. With EE 9 as the minimum and EE 10 supported already, Spring is prepared to provide out-of-the-box support for the further evolution of the Jakarta EE APIs. Spring Framework 6.0 is fully compatible with Tomcat 10.1, Jetty 11 and Undertow 2.3 as web servers, and also with Hibernate ORM 6.1. Over time, the role of Java/Jakarta EE in application development has evolved. In the early days of J2EE and Spring, applications were created to be deployed to an application server. Today, with the help of Spring Boot, applications are created in a devops- and cloud-friendly way, with the Servlet container embedded and trivial to change. As of Spring Framework 5, a WebFlux application does not even use the Servlet API directly and can run on servers (such as Netty) that are not Servlet containers. Spring continues to innovate and to evolve. Beyond the Spring Framework, there are other projects, such as Spring Boot, Spring Security, Spring Data, Spring Cloud, Spring Batch, among others. It’s important to remember that each project has its own source code repository, issue tracker, and release cadence. See spring.io/projects for the complete list of Spring projects. 1.3. Design Philosophy When you learn about a framework, it’s important to know not only what it does but what principles it follows. Here are the guiding principles of the Spring Framework: • Provide choice at every level. Spring lets you defer design decisions as late as possible. For example, you can switch persistence providers through configuration without changing your code. The same is true for many other infrastructure concerns and integration with third-party APIs. • Accommodate diverse perspectives. Spring embraces flexibility and is not opinionated about how things should be done. It supports a wide range of application needs with different perspectives. • Maintain strong backward compatibility. Spring’s evolution has been carefully managed to force few breaking changes between versions. Spring supports a carefully chosen range of JDK versions and third-party libraries to facilitate maintenance of applications and libraries that depend on Spring. • Care about API design. The Spring team puts a lot of thought and time into making APIs that are intuitive and that hold up across many versions and many years. • Set high standards for code quality. The Spring Framework puts a strong emphasis on meaningful, current, and accurate javadoc. It is one of very few projects that can claim clean code structure with no circular dependencies between packages. 1.4. Feedback and Contributions For how-to questions or diagnosing or debugging issues, we suggest using Stack Overflow. Click here for a list of the suggested tags to use on Stack Overflow. If you’re fairly certain that there is a problem in the Spring Framework or would like to suggest a feature, please use the GitHub Issues. If you have a solution in mind or a suggested fix, you can submit a pull request on Github. However, please keep in mind that, for all but the most trivial issues, we expect a ticket to be filed in the issue tracker, where discussions take place and leave a record for future reference. For more details see the guidelines at the CONTRIBUTING, top-level project page. 1.5. Getting Started If you are just getting started with Spring, you may want to begin using the Spring Framework by creating a Spring Boot-based application. Spring Boot provides a quick (and opinionated) way to create a production-ready Spring-based application. It is based on the Spring Framework, favors convention over configuration, and is designed to get you up and running as quickly as possible. You can use start.spring.io to generate a basic project or follow one of the "Getting Started" guides, such as Getting Started Building a RESTful Web Service. As well as being easier to digest, these guides are very task focused, and most of them are based on Spring Boot. They also cover other projects from the Spring portfolio that you might want to consider when solving a particular problem. Chapter 2. Core Technologies This part of the reference documentation covers all the technologies that are absolutely integral to the Spring Framework. Foremost amongst these is the Spring Framework’s Inversion of Control (IoC) container. A thorough treatment of the Spring Framework’s IoC container is closely followed by comprehensive coverage of Spring’s Aspect-Oriented Programming (AOP) technologies. The Spring Framework has its own AOP framework, which is conceptually easy to understand and which successfully addresses the 80% sweet spot of AOP requirements in Java enterprise programming. Coverage of Spring’s integration with AspectJ (currently the richest — in terms of features — and certainly most mature AOP implementation in the Java enterprise space) is also provided. AOT processing can be used to optimize your application ahead-of-time. It is typically used for native image deployment using GraalVM. 2.1. The IoC Container This chapter covers Spring’s Inversion of Control (IoC) container. 2.1.1. Introduction to the Spring IoC Container and Beans This chapter covers the Spring Framework implementation of the Inversion of Control (IoC) principle. IoC is also known as dependency injection (DI). It is a process whereby objects define their dependencies (that is, the other objects they work with) only through constructor arguments, arguments to a factory method, or properties that are set on the object instance after it is constructed or returned from a factory method. The container then injects those dependencies when it creates the bean. This process is fundamentally the inverse (hence the name, Inversion of Control) of the bean itself controlling the instantiation or location of its dependencies by using direct construction of classes or a mechanism such as the Service Locator pattern. The org.springframework.beans and org.springframework.context packages are the basis for Spring Framework’s IoC container. The BeanFactory interface provides an advanced configuration mechanism capable of managing any type of object. ApplicationContext is a sub-interface of BeanFactory. It adds: • Easier integration with Spring’s AOP features • Message resource handling (for use in internationalization) • Event publication • Application-layer specific contexts such as the WebApplicationContext for use in web applications. In short, the BeanFactory provides the configuration framework and basic functionality, and the ApplicationContext adds more enterprise-specific functionality. The ApplicationContext is a complete superset of the BeanFactory and is used exclusively in this chapter in descriptions of Spring’s IoC container. For more information on using the BeanFactory instead of the ApplicationContext, see the section covering the BeanFactory API. In Spring, the objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your application. Beans, and the dependencies among them, are reflected in the configuration metadata used by a container. 2.1.2. Container Overview The org.springframework.context.ApplicationContext interface represents the Spring IoC container and is responsible for instantiating, configuring, and assembling the beans. The container gets its instructions on what objects to instantiate, configure, and assemble by reading configuration metadata. The configuration metadata is represented in XML, Java annotations, or Java code. It lets you express the objects that compose your application and the rich interdependencies between those objects. Several implementations of the ApplicationContext interface are supplied with Spring. In stand- alone applications, it is common to create an instance of ClassPathXmlApplicationContext or FileSystemXmlApplicationContext. While XML has been the traditional format for defining configuration metadata, you can instruct the container to use Java annotations or code as the metadata format by providing a small amount of XML configuration to declaratively enable support for these additional metadata formats. In most application scenarios, explicit user code is not required to instantiate one or more instances of a Spring IoC container. For example, in a web application scenario, a simple eight (or so) lines of boilerplate web descriptor XML in the web.xml file of the application typically suffices (see Convenient ApplicationContext Instantiation for Web Applications). If you use the Spring Tools for Eclipse (an Eclipse-powered development environment), you can easily create this boilerplate configuration with a few mouse clicks or keystrokes. The following diagram shows a high-level view of how Spring works. Your application classes are combined with configuration metadata so that, after the ApplicationContext is created and initialized, you have a fully configured and executable system or application. Figure 1. The Spring IoC container Configuration Metadata As the preceding diagram shows, the Spring IoC container consumes a form of configuration metadata. This configuration metadata represents how you, as an application developer, tell the Spring container to instantiate, configure, and assemble the objects in your application. Configuration metadata is traditionally supplied in a simple and intuitive XML format, which is what most of this chapter uses to convey key concepts and features of the Spring IoC container. XML-based metadata is not the only allowed form of configuration metadata. The Spring IoC container itself is totally decoupled from the format in which this  configuration metadata is actually written. These days, many developers choose Java-based configuration for their Spring applications. For information about using other forms of metadata with the Spring container, see: • Annotation-based configuration: Spring 2.5 introduced support for annotation-based configuration metadata. • Java-based configuration: Starting with Spring 3.0, many features provided by the Spring JavaConfig project became part of the core Spring Framework. Thus, you can define beans external to your application classes by using Java rather than XML files. To use these new features, see the @Configuration, @Bean, @Import, and @DependsOn annotations. Spring configuration consists of at least one and typically more than one bean definition that the container must manage. XML-based configuration metadata configures these beans as elements inside a top-level element. Java configuration typically uses @Bean-annotated methods within a @Configuration class. These bean definitions correspond to the actual objects that make up your application. Typically, you define service layer objects, data access objects (DAOs), presentation objects such as Struts Action instances, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so forth. Typically, one does not configure fine-grained domain objects in the container, because it is usually the responsibility of DAOs and business logic to create and load domain objects. However, you can use Spring’s integration with AspectJ to configure objects that have been created outside the control of an IoC container. See Using AspectJ to dependency-inject domain objects with Spring. The following example shows the basic structure of XML-based configuration metadata:   ① ②             ① The id attribute is a string that identifies the individual bean definition. ② The class attribute defines the type of the bean and uses the fully qualified classname. The value of the id attribute refers to collaborating objects. The XML for referring to collaborating objects is not shown in this example. See Dependencies for more information. Instantiating a Container The location path or paths supplied to an ApplicationContext constructor are resource strings that let the container load configuration metadata from a variety of external resources, such as the local file system, the Java CLASSPATH, and so on. Java ApplicationContext context = new ClassPathXmlApplicationContext("services.xml", "daos.xml"); Kotlin val context = ClassPathXmlApplicationContext("services.xml", "daos.xml") After you learn about Spring’s IoC container, you may want to know more about Spring’s Resource abstraction (as described in Resources), which provides a  convenient mechanism for reading an InputStream from locations defined in a URI syntax. In particular, Resource paths are used to construct applications contexts, as described in Application Contexts and Resource Paths. The following example shows the service layer objects (services.xml) configuration file:               The following example shows the data access objects daos.xml file:               In the preceding example, the service layer consists of the PetStoreServiceImpl class and two data access objects of the types JpaAccountDao and JpaItemDao (based on the JPA Object-Relational Mapping standard). The property name element refers to the name of the JavaBean property, and the ref element refers to the name of another bean definition. This linkage between id and ref elements expresses the dependency between collaborating objects. For details of configuring an object’s dependencies, see Dependencies. Composing XML-based Configuration Metadata It can be useful to have bean definitions span multiple XML files. Often, each individual XML configuration file represents a logical layer or module in your architecture. You can use the application context constructor to load bean definitions from all these XML fragments. This constructor takes multiple Resource locations, as was shown in the previous section. Alternatively, use one or more occurrences of the element to load bean definitions from another file or files. The following example shows how to do so:           In the preceding example, external bean definitions are loaded from three files: services.xml, messageSource.xml, and themeSource.xml. All location paths are relative to the definition file doing the importing, so services.xml must be in the same directory or classpath location as the file doing the importing, while messageSource.xml and themeSource.xml must be in a resources location below the location of the importing file. As you can see, a leading slash is ignored. However, given that these paths are relative, it is better form not to use the slash at all. The contents of the files being imported, including the top level element, must be valid XML bean definitions, according to the Spring Schema. It is possible, but not recommended, to reference files in parent directories using a relative "../" path. Doing so creates a dependency on a file that is outside the current application. In particular, this reference is not recommended for classpath: URLs (for example, classpath:../services.xml), where the runtime resolution process chooses the “nearest” classpath root and then looks into its parent directory. Classpath configuration changes may lead to the choice of a different, incorrect directory.  You can always use fully qualified resource locations instead of relative paths: for example, file:C:/config/services.xml or classpath:/config/services.xml. However, be aware that you are coupling your application’s configuration to specific absolute locations. It is generally preferable to keep an indirection for such absolute locations — for example, through "${…}" placeholders that are resolved against JVM system properties at runtime. The namespace itself provides the import directive feature. Further configuration features beyond plain bean definitions are available in a selection of XML namespaces provided by Spring — for example, the context and util namespaces. The Groovy Bean Definition DSL As a further example for externalized configuration metadata, bean definitions can also be expressed in Spring’s Groovy Bean Definition DSL, as known from the Grails framework. Typically, such configuration live in a ".groovy" file with the structure shown in the following example: beans {   dataSource(BasicDataSource) {   driverClassName = "org.hsqldb.jdbcDriver"   url = "jdbc:hsqldb:mem:grailsDB"   username = "sa"   password = ""   settings = [mynew:"setting"]   }   sessionFactory(SessionFactory) {   dataSource = dataSource   }   myService(MyService) {   nestedBean = { AnotherBean bean ->   dataSource = dataSource   }   } } This configuration style is largely equivalent to XML bean definitions and even supports Spring’s XML configuration namespaces. It also allows for importing XML bean definition files through an importBeans directive. Using the Container The ApplicationContext is the interface for an advanced factory capable of maintaining a registry of different beans and their dependencies. By using the method T getBean(String name, Class requiredType), you can retrieve instances of your beans. The ApplicationContext lets you read bean definitions and access them, as the following example shows: Java // create and configure beans ApplicationContext context = new ClassPathXmlApplicationContext("services.xml", "daos.xml"); // retrieve configured instance PetStoreService service = context.getBean("petStore", PetStoreService.class); // use configured instance List userList = service.getUsernameList(); Kotlin import org.springframework.beans.factory.getBean // create and configure beans val context = ClassPathXmlApplicationContext("services.xml", "daos.xml") // retrieve configured instance val service = context.getBean("petStore") // use configured instance var userList = service.getUsernameList() With Groovy configuration, bootstrapping looks very similar. It has a different context implementation class which is Groovy-aware (but also understands XML bean definitions). The following example shows Groovy configuration: Java ApplicationContext context = new GenericGroovyApplicationContext("services.groovy", "daos.groovy"); Kotlin val context = GenericGroovyApplicationContext("services.groovy", "daos.groovy") The most flexible variant is GenericApplicationContext in combination with reader delegates — for example, with XmlBeanDefinitionReader for XML files, as the following example shows: Java GenericApplicationContext context = new GenericApplicationContext(); new XmlBeanDefinitionReader(context).loadBeanDefinitions("services.xml", "daos.xml"); context.refresh(); Kotlin val context = GenericApplicationContext() XmlBeanDefinitionReader(context).loadBeanDefinitions("services.xml", "daos.xml") context.refresh() You can also use the GroovyBeanDefinitionReader for Groovy files, as the following example shows: Java GenericApplicationContext context = new GenericApplicationContext(); new GroovyBeanDefinitionReader(context).loadBeanDefinitions("services.groovy", "daos.groovy"); context.refresh(); Kotlin val context = GenericApplicationContext() GroovyBeanDefinitionReader(context).loadBeanDefinitions("services.groovy", "daos.groovy") context.refresh() You can mix and match such reader delegates on the same ApplicationContext, reading bean definitions from diverse configuration sources. You can then use getBean to retrieve instances of your beans. The ApplicationContext interface has a few other methods for retrieving beans, but, ideally, your application code should never use them. Indeed, your application code should have no calls to the getBean() method at all and thus have no dependency on Spring APIs at all. For example, Spring’s integration with web frameworks provides dependency injection for various web framework components such as controllers and JSF-managed beans, letting you declare a dependency on a specific bean through metadata (such as an autowiring annotation). 2.1.3. Bean Overview A Spring IoC container manages one or more beans. These beans are created with the configuration metadata that you supply to the container (for example, in the form of XML definitions). Within the container itself, these bean definitions are represented as BeanDefinition objects, which contain (among other information) the following metadata: • A package-qualified class name: typically, the actual implementation class of the bean being defined. • Bean behavioral configuration elements, which state how the bean should behave in the container (scope, lifecycle callbacks, and so forth). • References to other beans that are needed for the bean to do its work. These references are also called collaborators or dependencies. • Other configuration settings to set in the newly created object — for example, the size limit of the pool or the number of connections to use in a bean that manages a connection pool. This metadata translates to a set of properties that make up each bean definition. The following table describes these properties: Table 1. The bean definition Property Explained in… Class Instantiating Beans Name Naming Beans Scope Bean Scopes Constructor arguments Dependency Injection Properties Dependency Injection Autowiring mode Autowiring Collaborators Lazy initialization mode Lazy-initialized Beans Initialization method Initialization Callbacks Destruction method Destruction Callbacks In addition to bean definitions that contain information on how to create a specific bean, the ApplicationContext implementations also permit the registration of existing objects that are created outside the container (by users). This is done by accessing the ApplicationContext’s BeanFactory through the getBeanFactory() method, which returns the DefaultListableBeanFactory implementation. DefaultListableBeanFactory supports this registration through the registerSingleton(..) and registerBeanDefinition(..) methods. However, typical applications work solely with beans defined through regular bean definition metadata. Bean metadata and manually supplied singleton instances need to be registered as early as possible, in order for the container to properly reason about them during autowiring and other introspection steps. While overriding existing metadata and  existing singleton instances is supported to some degree, the registration of new beans at runtime (concurrently with live access to the factory) is not officially supported and may lead to concurrent access exceptions, inconsistent state in the bean container, or both. Naming Beans Every bean has one or more identifiers. These identifiers must be unique within the container that hosts the bean. A bean usually has only one identifier. However, if it requires more than one, the extra ones can be considered aliases. In XML-based configuration metadata, you use the id attribute, the name attribute, or both to specify the bean identifiers. The id attribute lets you specify exactly one id. Conventionally, these names are alphanumeric ('myBean', 'someService', etc.), but they can contain special characters as well. If you want to introduce other aliases for the bean, you can also specify them in the name attribute, separated by a comma (,), semicolon (;), or white space. As a historical note, in versions prior to Spring 3.1, the id attribute was defined as an xsd:ID type, which constrained possible characters. As of 3.1, it is defined as an xsd:string type. Note that bean id uniqueness is still enforced by the container, though no longer by XML parsers. You are not required to supply a name or an id for a bean. If you do not supply a name or id explicitly, the container generates a unique name for that bean. However, if you want to refer to that bean by name, through the use of the ref element or a Service Locator style lookup, you must provide a name. Motivations for not supplying a name are related to using inner beans and autowiring collaborators. Bean Naming Conventions The convention is to use the standard Java convention for instance field names when naming beans. That is, bean names start with a lowercase letter and are camel-cased from there. Examples of such names include accountManager, accountService, userDao, loginController, and so forth. Naming beans consistently makes your configuration easier to read and understand. Also, if you use Spring AOP, it helps a lot when applying advice to a set of beans related by name. With component scanning in the classpath, Spring generates bean names for unnamed components, following the rules described earlier: essentially, taking the simple class name and turning its initial character to lower-case. However, in the  (unusual) special case when there is more than one character and both the first and second characters are upper case, the original casing gets preserved. These are the same rules as defined by java.beans.Introspector.decapitalize (which Spring uses here). Aliasing a Bean outside the Bean Definition In a bean definition itself, you can supply more than one name for the bean, by using a combination of up to one name specified by the id attribute and any number of other names in the name attribute. These names can be equivalent aliases to the same bean and are useful for some situations, such as letting each component in an application refer to a common dependency by using a bean name that is specific to that component itself. Specifying all aliases where the bean is actually defined is not always adequate, however. It is sometimes desirable to introduce an alias for a bean that is defined elsewhere. This is commonly the case in large systems where configuration is split amongst each subsystem, with each subsystem having its own set of object definitions. In XML-based configuration metadata, you can use the element to accomplish this. The following example shows how to do so: In this case, a bean (in the same container) named fromName may also, after the use of this alias definition, be referred to as toName. For example, the configuration metadata for subsystem A may refer to a DataSource by the name of subsystemA-dataSource. The configuration metadata for subsystem B may refer to a DataSource by the name of subsystemB-dataSource. When composing the main application that uses both these subsystems, the main application refers to the DataSource by the name of myApp-dataSource. To have all three names refer to the same object, you can add the following alias definitions to the configuration metadata: Now each component and the main application can refer to the dataSource through a name that is unique and guaranteed not to clash with any other definition (effectively creating a namespace), yet they refer to the same bean. Java-configuration If you use Javaconfiguration, the @Bean annotation can be used to provide aliases. See Using the @Bean Annotation for details. Instantiating Beans A bean definition is essentially a recipe for creating one or more objects. The container looks at the recipe for a named bean when asked and uses the configuration metadata encapsulated by that bean definition to create (or acquire) an actual object. If you use XML-based configuration metadata, you specify the type (or class) of object that is to be instantiated in the class attribute of the element. This class attribute (which, internally, is a Class property on a BeanDefinition instance) is usually mandatory. (For exceptions, see Instantiation by Using an Instance Factory Method and Bean Definition Inheritance.) You can use the Class property in one of two ways: • Typically, to specify the bean class to be constructed in the case where the container itself directly creates the bean by calling its constructor reflectively, somewhat equivalent to Java code with the new operator. • To specify the actual class containing the static factory method that is invoked to create the object, in the less common case where the container invokes a static factory method on a class to create the bean. The object type returned from the invocation of the static factory method may be the same class or another class entirely. Nested class names If you want to configure a bean definition for a nested class, you may use either the binary name or the source name of the nested class. For example, if you have a class called SomeThing in the com.example package, and this SomeThing class has a static nested class called OtherThing, they can be separated by a dollar sign ($) or a dot (.). So the value of the class attribute in a bean definition would be com.example.SomeThing$OtherThing or com.example.SomeThing.OtherThing. Instantiation with a Constructor When you create a bean by the constructor approach, all normal classes are usable by and compatible with Spring. That is, the class being developed does not need to implement any specific interfaces or to be coded in a specific fashion. Simply specifying the bean class should suffice. However, depending on what type of IoC you use for that specific bean, you may need a default (empty) constructor. The Spring IoC container can manage virtually any class you want it to manage. It is not limited to managing true JavaBeans. Most Spring users prefer actual JavaBeans with only a default (no- argument) constructor and appropriate setters and getters modeled after the properties in the container. You can also have more exotic non-bean-style classes in your container. If, for example, you need to use a legacy connection pool that absolutely does not adhere to the JavaBean specification, Spring can manage it as well. With XML-based configuration metadata you can specify your bean class as follows: For details about the mechanism for supplying arguments to the constructor (if required) and setting object instance properties after the object is constructed, see Injecting Dependencies. Instantiation with a Static Factory Method When defining a bean that you create with a static factory method, use the class attribute to specify the class that contains the static factory method and an attribute named factory-method to specify the name of the factory method itself. You should be able to call this method (with optional arguments, as described later) and return a live object, which subsequently is treated as if it had been created through a constructor. One use for such a bean definition is to call static factories in legacy code. The following bean definition specifies that the bean will be created by calling a factory method. The definition does not specify the type (class) of the returned object, but rather the class containing the factory method. In this example, the createInstance() method must be a static method. The following example shows how to specify a factory method: The following example shows a class that would work with the preceding bean definition: Java public class ClientService {   private static ClientService clientService = new ClientService();   private ClientService() {}   public static ClientService createInstance() {   return clientService;   } } Kotlin class ClientService private constructor() {   companion object {   private val clientService = ClientService()   @JvmStatic   fun createInstance() = clientService   } } For details about the mechanism for supplying (optional) arguments to the factory method and setting object instance properties after the object is returned from the factory, see Dependencies and Configuration in Detail. Instantiation by Using an Instance Factory Method Similar to instantiation through a static factory method, instantiation with an instance factory method invokes a non-static method of an existing bean from the container to create a new bean. To use this mechanism, leave the class attribute empty and, in the factory-bean attribute, specify the name of a bean in the current (or parent or ancestor) container that contains the instance method that is to be invoked to create the object. Set the name of the factory method itself with the factory-method attribute. The following example shows how to configure such a bean:   The following example shows the corresponding class: Java public class DefaultServiceLocator {   private static ClientService clientService = new ClientServiceImpl();   public ClientService createClientServiceInstance() {   return clientService;   } } Kotlin class DefaultServiceLocator {   companion object {   private val clientService = ClientServiceImpl()   }   fun createClientServiceInstance(): ClientService {   return clientService   } } One factory class can also hold more than one factory method, as the following example shows:   The following example shows the corresponding class: Java public class DefaultServiceLocator {   private static ClientService clientService = new ClientServiceImpl();   private static AccountService accountService = new AccountServiceImpl();   public ClientService createClientServiceInstance() {   return clientService;   }   public AccountService createAccountServiceInstance() {   return accountService;   } } Kotlin class DefaultServiceLocator {   companion object {   private val clientService = ClientServiceImpl()   private val accountService = AccountServiceImpl()   }   fun createClientServiceInstance(): ClientService {   return clientService   }   fun createAccountServiceInstance(): AccountService {   return accountService   } } This approach shows that the factory bean itself can be managed and configured through dependency injection (DI). See Dependencies and Configuration in Detail. In Spring documentation, "factory bean" refers to a bean that is configured in the Spring container and that creates objects through an instance or static factory  method. By contrast, FactoryBean (notice the capitalization) refers to a Spring- specific FactoryBean implementation class. Determining a Bean’s Runtime Type The runtime type of a specific bean is non-trivial to determine. A specified class in the bean metadata definition is just an initial class reference, potentially combined with a declared factory method or being a FactoryBean class which may lead to a different runtime type of the bean, or not being set at all in case of an instance-level factory method (which is resolved via the specified factory-bean name instead). Additionally, AOP proxying may wrap a bean instance with an interface-based proxy with limited exposure of the target bean’s actual type (just its implemented interfaces). The recommended way to find out about the actual runtime type of a particular bean is a BeanFactory.getType call for the specified bean name. This takes all of the above cases into account and returns the type of object that a BeanFactory.getBean call is going to return for the same bean name. 2.1.4. Dependencies A typical enterprise application does not consist of a single object (or bean in the Spring parlance). Even the simplest application has a few objects that work together to present what the end-user sees as a coherent application. This next section explains how you go from defining a number of bean definitions that stand alone to a fully realized application where objects collaborate to achieve a goal. Dependency Injection Dependency injection (DI) is a process whereby objects define their dependencies (that is, the other objects with which they work) only through constructor arguments, arguments to a factory method, or properties that are set on the object instance after it is constructed or returned from a factory method. The container then injects those dependencies when it creates the bean. This process is fundamentally the inverse (hence the name, Inversion of Control) of the bean itself controlling the instantiation or location of its dependencies on its own by using direct construction of classes or the Service Locator pattern. Code is cleaner with the DI principle, and decoupling is more effective when objects are provided with their dependencies. The object does not look up its dependencies and does not know the location or class of the dependencies. As a result, your classes become easier to test, particularly when the dependencies are on interfaces or abstract base classes, which allow for stub or mock implementations to be used in unit tests. DI exists in two major variants: Constructor-based dependency injection and Setter-based dependency injection. Constructor-based Dependency Injection Constructor-based DI is accomplished by the container invoking a constructor with a number of arguments, each representing a dependency. Calling a static factory method with specific arguments to construct the bean is nearly equivalent, and this discussion treats arguments to a constructor and to a static factory method similarly. The following example shows a class that can only be dependency-injected with constructor injection: Java public class SimpleMovieLister {   // the SimpleMovieLister has a dependency on a MovieFinder   private final MovieFinder movieFinder;   // a constructor so that the Spring container can inject a MovieFinder   public SimpleMovieLister(MovieFinder movieFinder) {   this.movieFinder = movieFinder;   }   // business logic that actually uses the injected MovieFinder is omitted... } Kotlin // a constructor so that the Spring container can inject a MovieFinder class SimpleMovieLister(private val movieFinder: MovieFinder) {   // business logic that actually uses the injected MovieFinder is omitted... } Notice that there is nothing special about this class. It is a POJO that has no dependencies on container specific interfaces, base classes, or annotations. Constructor Argument Resolution Constructor argument resolution matching occurs by using the argument’s type. If no potential ambiguity exists in the constructor arguments of a bean definition, the order in which the constructor arguments are defined in a bean definition is the order in which those arguments are supplied to the appropriate constructor when the bean is being instantiated. Consider the following class: Java package x.y; public class ThingOne {   public ThingOne(ThingTwo thingTwo, ThingThree thingThree) {   // ...   } } Kotlin package x.y class ThingOne(thingTwo: ThingTwo, thingThree: ThingThree) Assuming that the ThingTwo and ThingThree classes are not related by inheritance, no potential ambiguity exists. Thus, the following configuration works fine, and you do not need to specify the constructor argument indexes or types explicitly in the element.             When another bean is referenced, the type is known, and matching can occur (as was the case with the preceding example). When a simple type is used, such as true, Spring cannot determine the type of the value, and so cannot match by type without help. Consider the following class: Java package examples; public class ExampleBean {   // Number of years to calculate the Ultimate Answer   private final int years;   // The Answer to Life, the Universe, and Everything   private final String ultimateAnswer;   public ExampleBean(int years, String ultimateAnswer) {   this.years = years;   this.ultimateAnswer = ultimateAnswer;   } } Kotlin package examples class ExampleBean(   private val years: Int, // Number of years to calculate the Ultimate Answer   private val ultimateAnswer: String // The Answer to Life, the Universe, and Everything ) Constructor argument type matching In the preceding scenario, the container can use type matching with simple types if you explicitly specify the type of the constructor argument by using the type attribute, as the following example shows:     Constructor argument index You can use the index attribute to specify explicitly the index of constructor arguments, as the following example shows:     In addition to resolving the ambiguity of multiple simple values, specifying an index resolves ambiguity where a constructor has two arguments of the same type.  The index is 0-based. Constructor argument name You can also use the constructor parameter name for value disambiguation, as the following example shows:     Keep in mind that, to make this work out of the box, your code must be compiled with the debug flag enabled so that Spring can look up the parameter name from the constructor. If you cannot or do not want to compile your code with the debug flag, you can use the @ConstructorProperties JDK annotation to explicitly name your constructor arguments. The sample class would then have to look as follows: Java package examples; public class ExampleBean {   // Fields omitted   @ConstructorProperties({"years", "ultimateAnswer"})   public ExampleBean(int years, String ultimateAnswer) {   this.years = years;   this.ultimateAnswer = ultimateAnswer;   } } Kotlin package examples class ExampleBean @ConstructorProperties("years", "ultimateAnswer") constructor(val years: Int, val ultimateAnswer: String) Setter-based Dependency Injection Setter-based DI is accomplished by the container calling setter methods on your beans after invoking a no-argument constructor or a no-argument static factory method to instantiate your bean. The following example shows a class that can only be dependency-injected by using pure setter injection. This class is conventional Java. It is a POJO that has no dependencies on container specific interfaces, base classes, or annotations. Java public class SimpleMovieLister {   // the SimpleMovieLister has a dependency on the MovieFinder   private MovieFinder movieFinder;   // a setter method so that the Spring container can inject a MovieFinder   public void setMovieFinder(MovieFinder movieFinder) {   this.movieFinder = movieFinder;   }   // business logic that actually uses the injected MovieFinder is omitted... } Kotlin class SimpleMovieLister {   // a late-initialized property so that the Spring container can inject a MovieFinder   lateinit var movieFinder: MovieFinder   // business logic that actually uses the injected MovieFinder is omitted... } The ApplicationContext supports constructor-based and setter-based DI for the beans it manages. It also supports setter-based DI after some dependencies have already been injected through the constructor approach. You configure the dependencies in the form of a BeanDefinition, which you use in conjunction with PropertyEditor instances to convert properties from one format to another. However, most Spring users do not work with these classes directly (that is, programmatically) but rather with XML bean definitions, annotated components (that is, classes annotated with @Component, @Controller, and so forth), or @Bean methods in Java-based @Configuration classes. These sources are then converted internally into instances of BeanDefinition and used to load an entire Spring IoC container instance. Constructor-based or setter-based DI? Since you can mix constructor-based and setter-based DI, it is a good rule of thumb to use constructors for mandatory dependencies and setter methods or configuration methods for optional dependencies. Note that use of the @Autowired annotation on a setter method can be used to make the property be a required dependency; however, constructor injection with programmatic validation of arguments is preferable. The Spring team generally advocates constructor injection, as it lets you implement application components as immutable objects and ensures that required dependencies are not null. Furthermore, constructor-injected components are always returned to the client (calling) code in a fully initialized state. As a side note, a large number of constructor arguments is a bad code smell, implying that the class likely has too many responsibilities and should be refactored to better address proper separation of concerns. Setter injection should primarily only be used for optional dependencies that can be assigned reasonable default values within the class. Otherwise, not-null checks must be performed everywhere the code uses the dependency. One benefit of setter injection is that setter methods make objects of that class amenable to reconfiguration or re-injection later. Management through JMX MBeans is therefore a compelling use case for setter injection. Use the DI style that makes the most sense for a particular class. Sometimes, when dealing with third-party classes for which you do not have the source, the choice is made for you. For example, if a third-party class does not expose any setter methods, then constructor injection may be the only available form of DI. Dependency Resolution Process The container performs bean dependency resolution as follows: • The ApplicationContext is created and initialized with configuration metadata that describes all the beans. Configuration metadata can be specified by XML, Java code, or annotations. • For each bean, its dependencies are expressed in the form of properties, constructor arguments, or arguments to the static-factory method (if you use that instead of a normal constructor). These dependencies are provided to the bean, when the bean is actually created. • Each property or constructor argument is an actual definition of the value to set, or a reference to another bean in the container. • Each property or constructor argument that is a value is converted from its specified format to the actual type of that property or constructor argument. By default, Spring can convert a value supplied in string format to all built-in types, such as int, long, String, boolean, and so forth. The Spring container validates the configuration of each bean as the container is created. However, the bean properties themselves are not set until the bean is actually created. Beans that are singleton-scoped and set to be pre-instantiated (the default) are created when the container is created. Scopes are defined in Bean Scopes. Otherwise, the bean is created only when it is requested. Creation of a bean potentially causes a graph of beans to be created, as the bean’s dependencies and its dependencies' dependencies (and so on) are created and assigned. Note that resolution mismatches among those dependencies may show up late — that is, on first creation of the affected bean. Circular dependencies If you use predominantly constructor injection, it is possible to create an unresolvable circular dependency scenario. For example: Class A requires an instance of class B through constructor injection, and class B requires an instance of class A through constructor injection. If you configure beans for classes A and B to be injected into each other, the Spring IoC container detects this circular reference at runtime, and throws a BeanCurrentlyInCreationException. One possible solution is to edit the source code of some classes to be configured by setters rather than constructors. Alternatively, avoid constructor injection and use setter injection only. In other words, although it is not recommended, you can configure circular dependencies with setter injection. Unlike the typical case (with no circular dependencies), a circular dependency between bean A and bean B forces one of the beans to be injected into the other prior to being fully initialized itself (a classic chicken-and-egg scenario). You can generally trust Spring to do the right thing. It detects configuration problems, such as references to non-existent beans and circular dependencies, at container load-time. Spring sets properties and resolves dependencies as late as possible, when the bean is actually created. This means that a Spring container that has loaded correctly can later generate an exception when you request an object if there is a problem creating that object or one of its dependencies — for example, the bean throws an exception as a result of a missing or invalid property. This potentially delayed visibility of some configuration issues is why ApplicationContext implementations by default pre-instantiate singleton beans. At the cost of some upfront time and memory to create these beans before they are actually needed, you discover configuration issues when the ApplicationContext is created, not later. You can still override this default behavior so that singleton beans initialize lazily, rather than being eagerly pre-instantiated. If no circular dependencies exist, when one or more collaborating beans are being injected into a dependent bean, each collaborating bean is totally configured prior to being injected into the dependent bean. This means that, if bean A has a dependency on bean B, the Spring IoC container completely configures bean B prior to invoking the setter method on bean A. In other words, the bean is instantiated (if it is not a pre-instantiated singleton), its dependencies are set, and the relevant lifecycle methods (such as a configured init method or the InitializingBean callback method) are invoked. Examples of Dependency Injection The following example uses XML-based configuration metadata for setter-based DI. A small part of a Spring XML configuration file specifies some bean definitions as follows:               The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   private AnotherBean beanOne;   private YetAnotherBean beanTwo;   private int i;   public void setBeanOne(AnotherBean beanOne) {   this.beanOne = beanOne;   }   public void setBeanTwo(YetAnotherBean beanTwo) {   this.beanTwo = beanTwo;   }   public void setIntegerProperty(int i) {   this.i = i;   } } Kotlin class ExampleBean {   lateinit var beanOne: AnotherBean   lateinit var beanTwo: YetAnotherBean   var i: Int = 0 } In the preceding example, setters are declared to match against the properties specified in the XML file. The following example uses constructor-based DI:               The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   private AnotherBean beanOne;   private YetAnotherBean beanTwo;   private int i;   public ExampleBean(   AnotherBean anotherBean, YetAnotherBean yetAnotherBean, int i) {   this.beanOne = anotherBean;   this.beanTwo = yetAnotherBean;   this.i = i;   } } Kotlin class ExampleBean(   private val beanOne: AnotherBean,   private val beanTwo: YetAnotherBean,   private val i: Int) The constructor arguments specified in the bean definition are used as arguments to the constructor of the ExampleBean. Now consider a variant of this example, where, instead of using a constructor, Spring is told to call a static factory method to return an instance of the object:       The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   // a private constructor   private ExampleBean(...) {   ...   }   // a static factory method; the arguments to this method can be   // considered the dependencies of the bean that is returned,   // regardless of how those arguments are actually used.   public static ExampleBean createInstance (   AnotherBean anotherBean, YetAnotherBean yetAnotherBean, int i) {   ExampleBean eb = new ExampleBean (...);   // some other operations...   return eb;   } } Kotlin class ExampleBean private constructor() {   companion object {   // a static factory method; the arguments to this method can be   // considered the dependencies of the bean that is returned,   // regardless of how those arguments are actually used.   @JvmStatic   fun createInstance(anotherBean: AnotherBean, yetAnotherBean: YetAnotherBean, i: Int): ExampleBean {   val eb = ExampleBean (...)   // some other operations...   return eb   }   } } Arguments to the static factory method are supplied by elements, exactly the same as if a constructor had actually been used. The type of the class being returned by the factory method does not have to be of the same type as the class that contains the static factory method (although, in this example, it is). An instance (non-static) factory method can be used in an essentially identical fashion (aside from the use of the factory-bean attribute instead of the class attribute), so we do not discuss those details here. Dependencies and Configuration in Detail As mentioned in the previous section, you can define bean properties and constructor arguments as references to other managed beans (collaborators) or as values defined inline. Spring’s XML-based configuration metadata supports sub-element types within its and elements for this purpose. Straight Values (Primitives, Strings, and so on) The value attribute of the element specifies a property or constructor argument as a human-readable string representation. Spring’s conversion service is used to convert these values from a String to the actual type of the property or argument. The following example shows various values being set:           The following example uses the p-namespace for even more succinct XML configuration:   The preceding XML is more succinct. However, typos are discovered at runtime rather than design time, unless you use an IDE (such as IntelliJ IDEA or the Spring Tools for Eclipse) that supports automatic property completion when you create bean definitions. Such IDE assistance is highly recommended. You can also configure a java.util.Properties instance, as follows:         jdbc.driver.className=com.mysql.jdbc.Driver   jdbc.url=jdbc:mysql://localhost:3306/mydb     The Spring container converts the text inside the element into a java.util.Properties instance by using the JavaBeans PropertyEditor mechanism. This is a nice shortcut, and is one of a few places where the Spring team do favor the use of the nested element over the value attribute style. The idref element The idref element is simply an error-proof way to pass the id (a string value - not a reference) of another bean in the container to a or element. The following example shows how to use it:       The preceding bean definition snippet is exactly equivalent (at runtime) to the following snippet:   The first form is preferable to the second, because using the idref tag lets the container validate at deployment time that the referenced, named bean actually exists. In the second variation, no validation is performed on the value that is passed to the targetName property of the client bean. Typos are only discovered (with most likely fatal results) when the client bean is actually instantiated. If the client bean is a prototype bean, this typo and the resulting exception may only be discovered long after the container is deployed. The local attribute on the idref element is no longer supported in the 4.0 beans XSD, since it does not provide value over a regular bean reference any more.  Change your existing idref local references to idref bean when upgrading to the 4.0 schema. A common place (at least in versions earlier than Spring 2.0) where the element brings value is in the configuration of AOP interceptors in a ProxyFactoryBean bean definition. Using elements when you specify the interceptor names prevents you from misspelling an interceptor ID. References to Other Beans (Collaborators) The ref element is the final element inside a or definition element. Here, you set the value of the specified property of a bean to be a reference to another bean (a collaborator) managed by the container. The referenced bean is a dependency of the bean whose property is to be set, and it is initialized on demand as needed before the property is set. (If the collaborator is a singleton bean, it may already be initialized by the container.) All references are ultimately a reference to another object. Scoping and validation depend on whether you specify the ID or name of the other object through the bean or parent attribute. Specifying the target bean through the bean attribute of the tag is the most general form and allows creation of a reference to any bean in the same container or parent container, regardless of whether it is in the same XML file. The value of the bean attribute may be the same as the id attribute of the target bean or be the same as one of the values in the name attribute of the target bean. The following example shows how to use a ref element: Specifying the target bean through the parent attribute creates a reference to a bean that is in a parent container of the current container. The value of the parent attribute may be the same as either the id attribute of the target bean or one of the values in the name attribute of the target bean. The target bean must be in a parent container of the current one. You should use this bean reference variant mainly when you have a hierarchy of containers and you want to wrap an existing bean in a parent container with a proxy that has the same name as the parent bean. The following pair of listings shows how to use the parent attribute:     class="org.springframework.aop.framework.ProxyFactoryBean">         The local attribute on the ref element is no longer supported in the 4.0 beans XSD,  since it does not provide value over a regular bean reference any more. Change your existing ref local references to ref bean when upgrading to the 4.0 schema. Inner Beans A element inside the or elements defines an inner bean, as the following example shows:               An inner bean definition does not require a defined ID or name. If specified, the container does not use such a value as an identifier. The container also ignores the scope flag on creation, because inner beans are always anonymous and are always created with the outer bean. It is not possible to access inner beans independently or to inject them into collaborating beans other than into the enclosing bean. As a corner case, it is possible to receive destruction callbacks from a custom scope — for example, for a request-scoped inner bean contained within a singleton bean. The creation of the inner bean instance is tied to its containing bean, but destruction callbacks let it participate in the request scope’s lifecycle. This is not a common scenario. Inner beans typically simply share their containing bean’s scope. Collections The , , , and elements set the properties and arguments of the Java Collection types List, Set, Map, and Properties, respectively. The following example shows how to use them:         administrator@example.org   support@example.org   development@example.org             a list element followed by a reference                             just some string       The value of a map key or value, or a set value, can also be any of the following elements: bean | ref | idref | list | set | map | props | value | null Collection Merging The Spring container also supports merging collections. An application developer can define a parent , , or element and have child , , or elements inherit and override values from the parent collection. That is, the child collection’s values are the result of merging the elements of the parent and child collections, with the child’s collection elements overriding values specified in the parent collection. This section on merging discusses the parent-child bean mechanism. Readers unfamiliar with parent and child bean definitions may wish to read the relevant section before continuing. The following example demonstrates collection merging:         administrator@example.com   support@example.com                 sales@example.com   support@example.co.uk       Notice the use of the merge=true attribute on the element of the adminEmails property of the child bean definition. When the child bean is resolved and instantiated by the container, the resulting instance has an adminEmails Properties collection that contains the result of merging the child’s adminEmails collection with the parent’s adminEmails collection. The following listing shows the result: administrator=administrator@example.com sales=sales@example.com support=support@example.co.uk The child Properties collection’s value set inherits all property elements from the parent , and the child’s value for the support value overrides the value in the parent collection. This merging behavior applies similarly to the , , and collection types. In the specific case of the element, the semantics associated with the List collection type (that is, the notion of an ordered collection of values) is maintained. The parent’s values precede all of the child list’s values. In the case of the Map, Set, and Properties collection types, no ordering exists. Hence, no ordering semantics are in effect for the collection types that underlie the associated Map, Set, and Properties implementation types that the container uses internally. Limitations of Collection Merging You cannot merge different collection types (such as a Map and a List). If you do attempt to do so, an appropriate Exception is thrown. The merge attribute must be specified on the lower, inherited, child definition. Specifying the merge attribute on a parent collection definition is redundant and does not result in the desired merging. Strongly-typed collection Thanks to Java’s support for generic types, you can use strongly typed collections. That is, it is possible to declare a Collection type such that it can only contain (for example) String elements. If you use Spring to dependency-inject a strongly-typed Collection into a bean, you can take advantage of Spring’s type-conversion support such that the elements of your strongly-typed Collection instances are converted to the appropriate type prior to being added to the Collection. The following Java class and bean definition show how to do so: Java public class SomeClass {   private Map accounts;   public void setAccounts(Map accounts) {   this.accounts = accounts;   } } Kotlin class SomeClass {   lateinit var accounts: Map }                   When the accounts property of the something bean is prepared for injection, the generics information about the element type of the strongly-typed Map is available by reflection. Thus, Spring’s type conversion infrastructure recognizes the various value elements as being of type Float, and the string values (9.99, 2.75, and 3.99) are converted into an actual Float type. Null and Empty String Values Spring treats empty arguments for properties and the like as empty Strings. The following XML- based configuration metadata snippet sets the email property to the empty String value ("").   The preceding example is equivalent to the following Java code: Java exampleBean.setEmail(""); Kotlin exampleBean.email = "" The element handles null values. The following listing shows an example:       The preceding configuration is equivalent to the following Java code: Java exampleBean.setEmail(null); Kotlin exampleBean.email = null XML Shortcut with the p-namespace The p-namespace lets you use the bean element’s attributes (instead of nested elements) to describe your property values collaborating beans, or both. Spring supports extensible configuration formats with namespaces, which are based on an XML Schema definition. The beans configuration format discussed in this chapter is defined in an XML Schema document. However, the p-namespace is not defined in an XSD file and exists only in the core of Spring. The following example shows two XML snippets (the first uses standard XML format and the second uses the p-namespace) that resolve to the same result:         The example shows an attribute in the p-namespace called email in the bean definition. This tells Spring to include a property declaration. As previously mentioned, the p-namespace does not have a schema definition, so you can set the name of the attribute to the property name. This next example includes two more bean definitions that both have a reference to another bean:                 This example includes not only a property value using the p-namespace but also uses a special format to declare property references. Whereas the first bean definition uses to create a reference from bean john to bean jane, the second bean definition uses p:spouse-ref="jane" as an attribute to do the exact same thing. In this case, spouse is the property name, whereas the -ref part indicates that this is not a straight value but rather a reference to another bean. The p-namespace is not as flexible as the standard XML format. For example, the format for declaring property references clashes with properties that end in Ref,  whereas the standard XML format does not. We recommend that you choose your approach carefully and communicate this to your team members to avoid producing XML documents that use all three approaches at the same time. XML Shortcut with the c-namespace Similar to the XML Shortcut with the p-namespace, the c-namespace, introduced in Spring 3.1, allows inlined attributes for configuring the constructor arguments rather then nested constructor- arg elements. The following example uses the c: namespace to do the same thing as the from Constructor-based Dependency Injection:                     The c: namespace uses the same conventions as the p: one (a trailing -ref for bean references) for setting the constructor arguments by their names. Similarly, it needs to be declared in the XML file even though it is not defined in an XSD schema (it exists inside the Spring core). For the rare cases where the constructor argument names are not available (usually if the bytecode was compiled without debugging information), you can use fallback to the argument indexes, as follows: Due to the XML grammar, the index notation requires the presence of the leading _, as XML attribute names cannot start with a number (even though some IDEs  allow it). A corresponding index notation is also available for elements but not commonly used since the plain order of declaration is usually sufficient there. In practice, the constructor resolution mechanism is quite efficient in matching arguments, so unless you really need to, we recommend using the name notation throughout your configuration. Compound Property Names You can use compound or nested property names when you set bean properties, as long as all components of the path except the final property name are not null. Consider the following bean definition:   The something bean has a fred property, which has a bob property, which has a sammy property, and that final sammy property is being set to a value of 123. In order for this to work, the fred property of something and the bob property of fred must not be null after the bean is constructed. Otherwise, a NullPointerException is thrown. Using depends-on If a bean is a dependency of another bean, that usually means that one bean is set as a property of another. Typically you accomplish this with the element in XML-based configuration metadata. However, sometimes dependencies between beans are less direct. An example is when a static initializer in a class needs to be triggered, such as for database driver registration. The depends-on attribute can explicitly force one or more beans to be initialized before the bean using this element is initialized. The following example uses the depends-on attribute to express a dependency on a single bean: To express a dependency on multiple beans, supply a list of bean names as the value of the depends- on attribute (commas, whitespace, and semicolons are valid delimiters):   The depends-on attribute can specify both an initialization-time dependency and, in the case of singleton beans only, a corresponding destruction-time dependency.  Dependent beans that define a depends-on relationship with a given bean are destroyed first, prior to the given bean itself being destroyed. Thus, depends-on can also control shutdown order. Lazy-initialized Beans By default, ApplicationContext implementations eagerly create and configure all singleton beans as part of the initialization process. Generally, this pre-instantiation is desirable, because errors in the configuration or surrounding environment are discovered immediately, as opposed to hours or even days later. When this behavior is not desirable, you can prevent pre-instantiation of a singleton bean by marking the bean definition as being lazy-initialized. A lazy-initialized bean tells the IoC container to create a bean instance when it is first requested, rather than at startup. In XML, this behavior is controlled by the lazy-init attribute on the element, as the following example shows: When the preceding configuration is consumed by an ApplicationContext, the lazy bean is not eagerly pre-instantiated when the ApplicationContext starts, whereas the not.lazy bean is eagerly pre-instantiated. However, when a lazy-initialized bean is a dependency of a singleton bean that is not lazy- initialized, the ApplicationContext creates the lazy-initialized bean at startup, because it must satisfy the singleton’s dependencies. The lazy-initialized bean is injected into a singleton bean elsewhere that is not lazy-initialized. You can also control lazy-initialization at the container level by using the default-lazy-init attribute on the element, as the following example shows:   Autowiring Collaborators The Spring container can autowire relationships between collaborating beans. You can let Spring resolve collaborators (other beans) automatically for your bean by inspecting the contents of the ApplicationContext. Autowiring has the following advantages: • Autowiring can significantly reduce the need to specify properties or constructor arguments. (Other mechanisms such as a bean template discussed elsewhere in this chapter are also valuable in this regard.) • Autowiring can update a configuration as your objects evolve. For example, if you need to add a dependency to a class, that dependency can be satisfied automatically without you needing to modify the configuration. Thus autowiring can be especially useful during development, without negating the option of switching to explicit wiring when the code base becomes more stable. When using XML-based configuration metadata (see Dependency Injection), you can specify the autowire mode for a bean definition with the autowire attribute of the element. The autowiring functionality has four modes. You specify autowiring per bean and can thus choose which ones to autowire. The following table describes the four autowiring modes: Table 2. Autowiring modes Mode Explanation no (Default) No autowiring. Bean references must be defined by ref elements. Changing the default setting is not recommended for larger deployments, because specifying collaborators explicitly gives greater control and clarity. To some extent, it documents the structure of a system. byName Autowiring by property name. Spring looks for a bean with the same name as the property that needs to be autowired. For example, if a bean definition is set to autowire by name and it contains a master property (that is, it has a setMaster(..) method), Spring looks for a bean definition named master and uses it to set the property. byType Lets a property be autowired if exactly one bean of the property type exists in the container. If more than one exists, a fatal exception is thrown, which indicates that you may not use byType autowiring for that bean. If there are no matching beans, nothing happens (the property is not set). constructor Analogous to byType but applies to constructor arguments. If there is not exactly one bean of the constructor argument type in the container, a fatal error is raised. With byType or constructor autowiring mode, you can wire arrays and typed collections. In such cases, all autowire candidates within the container that match the expected type are provided to satisfy the dependency. You can autowire strongly-typed Map instances if the expected key type is String. An autowired Map instance’s values consist of all bean instances that match the expected type, and the Map instance’s keys contain the corresponding bean names. Limitations and Disadvantages of Autowiring Autowiring works best when it is used consistently across a project. If autowiring is not used in general, it might be confusing to developers to use it to wire only one or two bean definitions. Consider the limitations and disadvantages of autowiring: • Explicit dependencies in property and constructor-arg settings always override autowiring. You cannot autowire simple properties such as primitives, Strings, and Classes (and arrays of such simple properties). This limitation is by-design. • Autowiring is less exact than explicit wiring. Although, as noted in the earlier table, Spring is careful to avoid guessing in case of ambiguity that might have unexpected results. The relationships between your Spring-managed objects are no longer documented explicitly. • Wiring information may not be available to tools that may generate documentation from a Spring container. • Multiple bean definitions within the container may match the type specified by the setter method or constructor argument to be autowired. For arrays, collections, or Map instances, this is not necessarily a problem. However, for dependencies that expect a single value, this ambiguity is not arbitrarily resolved. If no unique bean definition is available, an exception is thrown. In the latter scenario, you have several options: • Abandon autowiring in favor of explicit wiring. • Avoid autowiring for a bean definition by setting its autowire-candidate attributes to false, as described in the next section. • Designate a single bean definition as the primary candidate by setting the primary attribute of its element to true. • Implement the more fine-grained control available with annotation-based configuration, as described in Annotation-based Container Configuration. Excluding a Bean from Autowiring On a per-bean basis, you can exclude a bean from autowiring. In Spring’s XML format, set the autowire-candidate attribute of the element to false. The container makes that specific bean definition unavailable to the autowiring infrastructure (including annotation style configurations such as @Autowired). The autowire-candidate attribute is designed to only affect type-based autowiring. It does not affect explicit references by name, which get resolved even if the  specified bean is not marked as an autowire candidate. As a consequence, autowiring by name nevertheless injects a bean if the name matches. You can also limit autowire candidates based on pattern-matching against bean names. The top- level element accepts one or more patterns within its default-autowire-candidates attribute. For example, to limit autowire candidate status to any bean whose name ends with Repository, provide a value of *Repository. To provide multiple patterns, define them in a comma- separated list. An explicit value of true or false for a bean definition’s autowire-candidate attribute always takes precedence. For such beans, the pattern matching rules do not apply. These techniques are useful for beans that you never want to be injected into other beans by autowiring. It does not mean that an excluded bean cannot itself be configured by using autowiring. Rather, the bean itself is not a candidate for autowiring other beans. Method Injection In most application scenarios, most beans in the container are singletons. When a singleton bean needs to collaborate with another singleton bean or a non-singleton bean needs to collaborate with another non-singleton bean, you typically handle the dependency by defining one bean as a property of the other. A problem arises when the bean lifecycles are different. Suppose singleton bean A needs to use non-singleton (prototype) bean B, perhaps on each method invocation on A. The container creates the singleton bean A only once, and thus only gets one opportunity to set the properties. The container cannot provide bean A with a new instance of bean B every time one is needed. A solution is to forego some inversion of control. You can make bean A aware of the container by implementing the ApplicationContextAware interface, and by making a getBean("B") call to the container ask for (a typically new) bean B instance every time bean A needs it. The following example shows this approach: Java // a class that uses a stateful Command-style class to perform some processing package fiona.apple; // Spring-API imports import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; public class CommandManager implements ApplicationContextAware {   private ApplicationContext applicationContext;   public Object process(Map commandState) {   // grab a new instance of the appropriate Command   Command command = createCommand();   // set the state on the (hopefully brand new) Command instance   command.setState(commandState);   return command.execute();   }   protected Command createCommand() {   // notice the Spring API dependency!   return this.applicationContext.getBean("command", Command.class);   }   public void setApplicationContext(   ApplicationContext applicationContext) throws BeansException {   this.applicationContext = applicationContext;   } } Kotlin // a class that uses a stateful Command-style class to perform some processing package fiona.apple // Spring-API imports import org.springframework.context.ApplicationContext import org.springframework.context.ApplicationContextAware class CommandManager : ApplicationContextAware {   private lateinit var applicationContext: ApplicationContext   fun process(commandState: Map<*, *>): Any {   // grab a new instance of the appropriate Command   val command = createCommand()   // set the state on the (hopefully brand new) Command instance   command.state = commandState   return command.execute()   }   // notice the Spring API dependency!   protected fun createCommand() =   applicationContext.getBean("command", Command::class.java)   override fun setApplicationContext(applicationContext: ApplicationContext) {   this.applicationContext = applicationContext   } } The preceding is not desirable, because the business code is aware of and coupled to the Spring Framework. Method Injection, a somewhat advanced feature of the Spring IoC container, lets you handle this use case cleanly. You can read more about the motivation for Method Injection in this blog entry. Lookup Method Injection Lookup method injection is the ability of the container to override methods on container-managed beans and return the lookup result for another named bean in the container. The lookup typically involves a prototype bean, as in the scenario described in the preceding section. The Spring Framework implements this method injection by using bytecode generation from the CGLIB library to dynamically generate a subclass that overrides the method. • For this dynamic subclassing to work, the class that the Spring bean container subclasses cannot be final, and the method to be overridden cannot be final, either. • Unit-testing a class that has an abstract method requires you to subclass the class yourself and to supply a stub implementation of the abstract method.  • Concrete methods are also necessary for component scanning, which requires concrete classes to pick up. • A further key limitation is that lookup methods do not work with factory methods and in particular not with @Bean methods in configuration classes, since, in that case, the container is not in charge of creating the instance and therefore cannot create a runtime-generated subclass on the fly. In the case of the CommandManager class in the previous code snippet, the Spring container dynamically overrides the implementation of the createCommand() method. The CommandManager class does not have any Spring dependencies, as the reworked example shows: Java package fiona.apple; // no more Spring imports! public abstract class CommandManager {   public Object process(Object commandState) {   // grab a new instance of the appropriate Command interface   Command command = createCommand();   // set the state on the (hopefully brand new) Command instance   command.setState(commandState);   return command.execute();   }   // okay... but where is the implementation of this method?   protected abstract Command createCommand(); } Kotlin package fiona.apple // no more Spring imports! abstract class CommandManager {   fun process(commandState: Any): Any {   // grab a new instance of the appropriate Command interface   val command = createCommand()   // set the state on the (hopefully brand new) Command instance   command.state = commandState   return command.execute()   }   // okay... but where is the implementation of this method?   protected abstract fun createCommand(): Command } In the client class that contains the method to be injected (the CommandManager in this case), the method to be injected requires a signature of the following form: [abstract] theMethodName(no-arguments); If the method is abstract, the dynamically-generated subclass implements the method. Otherwise, the dynamically-generated subclass overrides the concrete method defined in the original class. Consider the following example:     The bean identified as commandManager calls its own createCommand() method whenever it needs a new instance of the myCommand bean. You must be careful to deploy the myCommand bean as a prototype if that is actually what is needed. If it is a singleton, the same instance of the myCommand bean is returned each time. Alternatively, within the annotation-based component model, you can declare a lookup method through the @Lookup annotation, as the following example shows: Java public abstract class CommandManager {   public Object process(Object commandState) {   Command command = createCommand();   command.setState(commandState);   return command.execute();   }   @Lookup("myCommand")   protected abstract Command createCommand(); } Kotlin abstract class CommandManager {   fun process(commandState: Any): Any {   val command = createCommand()   command.state = commandState   return command.execute()   }   @Lookup("myCommand")   protected abstract fun createCommand(): Command } Or, more idiomatically, you can rely on the target bean getting resolved against the declared return type of the lookup method: Java public abstract class CommandManager {   public Object process(Object commandState) {   Command command = createCommand();   command.setState(commandState);   return command.execute();   }   @Lookup   protected abstract Command createCommand(); } Kotlin abstract class CommandManager {   fun process(commandState: Any): Any {   val command = createCommand()   command.state = commandState   return command.execute()   }   @Lookup   protected abstract fun createCommand(): Command } Note that you should typically declare such annotated lookup methods with a concrete stub implementation, in order for them to be compatible with Spring’s component scanning rules where abstract classes get ignored by default. This limitation does not apply to explicitly registered or explicitly imported bean classes. Another way of accessing differently scoped target beans is an ObjectFactory/ Provider injection point. See Scoped Beans as Dependencies.  You may also find the ServiceLocatorFactoryBean (in the org.springframework.beans.factory.config package) to be useful. Arbitrary Method Replacement A less useful form of method injection than lookup method injection is the ability to replace arbitrary methods in a managed bean with another method implementation. You can safely skip the rest of this section until you actually need this functionality. With XML-based configuration metadata, you can use the replaced-method element to replace an existing method implementation with another, for a deployed bean. Consider the following class, which has a method called computeValue that we want to override: Java public class MyValueCalculator {   public String computeValue(String input) {   // some real code...   }   // some other methods... } Kotlin class MyValueCalculator {   fun computeValue(input: String): String {   // some real code...   }   // some other methods... } A class that implements the org.springframework.beans.factory.support.MethodReplacer interface provides the new method definition, as the following example shows: Java /**  * meant to be used to override the existing computeValue(String)  * implementation in MyValueCalculator  */ public class ReplacementComputeValue implements MethodReplacer {   public Object reimplement(Object o, Method m, Object[] args) throws Throwable {   // get the input value, work with it, and return a computed result   String input = (String) args[0];   ...   return ...;   } } Kotlin /**  * meant to be used to override the existing computeValue(String)  * implementation in MyValueCalculator  */ class ReplacementComputeValue : MethodReplacer {   override fun reimplement(obj: Any, method: Method, args: Array): Any {   // get the input value, work with it, and return a computed result   val input = args[0] as String;   ...   return ...;   } } The bean definition to deploy the original class and specify the method override would resemble the following example:       String   You can use one or more elements within the element to indicate the method signature of the method being overridden. The signature for the arguments is necessary only if the method is overloaded and multiple variants exist within the class. For convenience, the type string for an argument may be a substring of the fully qualified type name. For example, the following all match java.lang.String: java.lang.String String Str Because the number of arguments is often enough to distinguish between each possible choice, this shortcut can save a lot of typing, by letting you type only the shortest string that matches an argument type. 2.1.5. Bean Scopes When you create a bean definition, you create a recipe for creating actual instances of the class defined by that bean definition. The idea that a bean definition is a recipe is important, because it means that, as with a class, you can create many object instances from a single recipe. You can control not only the various dependencies and configuration values that are to be plugged into an object that is created from a particular bean definition but also control the scope of the objects created from a particular bean definition. This approach is powerful and flexible, because you can choose the scope of the objects you create through configuration instead of having to bake in the scope of an object at the Java class level. Beans can be defined to be deployed in one of a number of scopes. The Spring Framework supports six scopes, four of which are available only if you use a web-aware ApplicationContext. You can also create a custom scope. The following table describes the supported scopes: Table 3. Bean scopes Scope Description singleton (Default) Scopes a single bean definition to a single object instance for each Spring IoC container. prototype Scopes a single bean definition to any number of object instances. Scope Description request Scopes a single bean definition to the lifecycle of a single HTTP request. That is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext. session Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext. application Scopes a single bean definition to the lifecycle of a ServletContext. Only valid in the context of a web-aware Spring ApplicationContext. websocket Scopes a single bean definition to the lifecycle of a WebSocket. Only valid in the context of a web-aware Spring ApplicationContext. As of Spring 3.0, a thread scope is available but is not registered by default. For  more information, see the documentation for SimpleThreadScope. For instructions on how to register this or any other custom scope, see Using a Custom Scope. The Singleton Scope Only one shared instance of a singleton bean is managed, and all requests for beans with an ID or IDs that match that bean definition result in that one specific bean instance being returned by the Spring container. To put it another way, when you define a bean definition and it is scoped as a singleton, the Spring IoC container creates exactly one instance of the object defined by that bean definition. This single instance is stored in a cache of such singleton beans, and all subsequent requests and references for that named bean return the cached object. The following image shows how the singleton scope works: Spring’s concept of a singleton bean differs from the singleton pattern as defined in the Gang of Four (GoF) patterns book. The GoF singleton hard-codes the scope of an object such that one and only one instance of a particular class is created per ClassLoader. The scope of the Spring singleton is best described as being per-container and per-bean. This means that, if you define one bean for a particular class in a single Spring container, the Spring container creates one and only one instance of the class defined by that bean definition. The singleton scope is the default scope in Spring. To define a bean as a singleton in XML, you can define a bean as shown in the following example: The Prototype Scope The non-singleton prototype scope of bean deployment results in the creation of a new bean instance every time a request for that specific bean is made. That is, the bean is injected into another bean or you request it through a getBean() method call on the container. As a rule, you should use the prototype scope for all stateful beans and the singleton scope for stateless beans. The following diagram illustrates the Spring prototype scope: (A data access object (DAO) is not typically configured as a prototype, because a typical DAO does not hold any conversational state. It was easier for us to reuse the core of the singleton diagram.) The following example defines a bean as a prototype in XML: In contrast to the other scopes, Spring does not manage the complete lifecycle of a prototype bean. The container instantiates, configures, and otherwise assembles a prototype object and hands it to the client, with no further record of that prototype instance. Thus, although initialization lifecycle callback methods are called on all objects regardless of scope, in the case of prototypes, configured destruction lifecycle callbacks are not called. The client code must clean up prototype-scoped objects and release expensive resources that the prototype beans hold. To get the Spring container to release resources held by prototype-scoped beans, try using a custom bean post-processor, which holds a reference to beans that need to be cleaned up. In some respects, the Spring container’s role in regard to a prototype-scoped bean is a replacement for the Java new operator. All lifecycle management past that point must be handled by the client. (For details on the lifecycle of a bean in the Spring container, see Lifecycle Callbacks.) Singleton Beans with Prototype-bean Dependencies When you use singleton-scoped beans with dependencies on prototype beans, be aware that dependencies are resolved at instantiation time. Thus, if you dependency-inject a prototype-scoped bean into a singleton-scoped bean, a new prototype bean is instantiated and then dependency- injected into the singleton bean. The prototype instance is the sole instance that is ever supplied to the singleton-scoped bean. However, suppose you want the singleton-scoped bean to acquire a new instance of the prototype- scoped bean repeatedly at runtime. You cannot dependency-inject a prototype-scoped bean into your singleton bean, because that injection occurs only once, when the Spring container instantiates the singleton bean and resolves and injects its dependencies. If you need a new instance of a prototype bean at runtime more than once, see Method Injection. Request, Session, Application, and WebSocket Scopes The request, session, application, and websocket scopes are available only if you use a web-aware Spring ApplicationContext implementation (such as XmlWebApplicationContext). If you use these scopes with regular Spring IoC containers, such as the ClassPathXmlApplicationContext, an IllegalStateException that complains about an unknown bean scope is thrown. Initial Web Configuration To support the scoping of beans at the request, session, application, and websocket levels (web- scoped beans), some minor initial configuration is required before you define your beans. (This initial setup is not required for the standard scopes: singleton and prototype.) How you accomplish this initial setup depends on your particular Servlet environment. If you access scoped beans within Spring Web MVC, in effect, within a request that is processed by the Spring DispatcherServlet, no special setup is necessary. DispatcherServlet already exposes all relevant state. If you use a Servlet web container, with requests processed outside of Spring’s DispatcherServlet (for example, when using JSF or Struts), you need to register the org.springframework.web.context.request.RequestContextListener ServletRequestListener. This can be done programmatically by using the WebApplicationInitializer interface. Alternatively, add the following declaration to your web application’s web.xml file:   ...       org.springframework.web.context.request.RequestContextListener       ... Alternatively, if there are issues with your listener setup, consider using Spring’s RequestContextFilter. The filter mapping depends on the surrounding web application configuration, so you have to change it as appropriate. The following listing shows the filter part of a web application:   ...     requestContextFilter   org.springframework.web.filter.RequestContextFilter       requestContextFilter   /*     ... DispatcherServlet, RequestContextListener, and RequestContextFilter all do exactly the same thing, namely bind the HTTP request object to the Thread that is servicing that request. This makes beans that are request- and session-scoped available further down the call chain. Request scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the LoginAction bean by using the loginAction bean definition for each and every HTTP request. That is, the loginAction bean is scoped at the HTTP request level. You can change the internal state of the instance that is created as much as you want, because other instances created from the same loginAction bean definition do not see these changes in state. They are particular to an individual request. When the request completes processing, the bean that is scoped to the request is discarded. When using annotation-driven components or Java configuration, the @RequestScope annotation can be used to assign a component to the request scope. The following example shows how to do so: Java @RequestScope @Component public class LoginAction {   // ... } Kotlin @RequestScope @Component class LoginAction {   // ... } Session Scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the UserPreferences bean by using the userPreferences bean definition for the lifetime of a single HTTP Session. In other words, the userPreferences bean is effectively scoped at the HTTP Session level. As with request-scoped beans, you can change the internal state of the instance that is created as much as you want, knowing that other HTTP Session instances that are also using instances created from the same userPreferences bean definition do not see these changes in state, because they are particular to an individual HTTP Session. When the HTTP Session is eventually discarded, the bean that is scoped to that particular HTTP Session is also discarded. When using annotation-driven components or Java configuration, you can use the @SessionScope annotation to assign a component to the session scope. Java @SessionScope @Component public class UserPreferences {   // ... } Kotlin @SessionScope @Component class UserPreferences {   // ... } Application Scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the AppPreferences bean by using the appPreferences bean definition once for the entire web application. That is, the appPreferences bean is scoped at the ServletContext level and stored as a regular ServletContext attribute. This is somewhat similar to a Spring singleton bean but differs in two important ways: It is a singleton per ServletContext, not per Spring ApplicationContext (for which there may be several in any given web application), and it is actually exposed and therefore visible as a ServletContext attribute. When using annotation-driven components or Java configuration, you can use the @ApplicationScope annotation to assign a component to the application scope. The following example shows how to do so: Java @ApplicationScope @Component public class AppPreferences {   // ... } Kotlin @ApplicationScope @Component class AppPreferences {   // ... } WebSocket Scope WebSocket scope is associated with the lifecycle of a WebSocket session and applies to STOMP over WebSocket applications, see WebSocket scope for more details. Scoped Beans as Dependencies The Spring IoC container manages not only the instantiation of your objects (beans), but also the wiring up of collaborators (or dependencies). If you want to inject (for example) an HTTP request- scoped bean into another bean of a longer-lived scope, you may choose to inject an AOP proxy in place of the scoped bean. That is, you need to inject a proxy object that exposes the same public interface as the scoped object but that can also retrieve the real target object from the relevant scope (such as an HTTP request) and delegate method calls onto the real object. You may also use between beans that are scoped as singleton, with the reference then going through an intermediate proxy that is serializable and therefore able to re-obtain the target singleton bean on deserialization. When declaring against a bean of scope prototype, every method call on the shared proxy leads to the creation of a new target instance to which the call is then being forwarded. Also, scoped proxies are not the only way to access beans from shorter scopes in a lifecycle-safe fashion. You may also declare your injection point (that is, the  constructor or setter argument or autowired field) as ObjectFactory, allowing for a getObject() call to retrieve the current instance on demand every time it is needed — without holding on to the instance or storing it separately. As an extended variant, you may declare ObjectProvider which delivers several additional access variants, including getIfAvailable and getIfUnique. The JSR-330 variant of this is called Provider and is used with a Provider declaration and a corresponding get() call for every retrieval attempt. See here for more details on JSR-330 overall. The configuration in the following example is only one line, but it is important to understand the “why” as well as the “how” behind it:         ①             ① The line that defines the proxy. To create such a proxy, you insert a child element into a scoped bean definition (see Choosing the Type of Proxy to Create and XML Schema-based configuration). Why do definitions of beans scoped at the request, session and custom-scope levels require the element? Consider the following singleton bean definition and contrast it with what you need to define for the aforementioned scopes (note that the following userPreferences bean definition as it stands is incomplete):   In the preceding example, the singleton bean (userManager) is injected with a reference to the HTTP Session-scoped bean (userPreferences). The salient point here is that the userManager bean is a singleton: it is instantiated exactly once per container, and its dependencies (in this case only one, the userPreferences bean) are also injected only once. This means that the userManager bean operates only on the exact same userPreferences object (that is, the one with which it was originally injected). This is not the behavior you want when injecting a shorter-lived scoped bean into a longer-lived scoped bean (for example, injecting an HTTP Session-scoped collaborating bean as a dependency into singleton bean). Rather, you need a single userManager object, and, for the lifetime of an HTTP Session, you need a userPreferences object that is specific to the HTTP Session. Thus, the container creates an object that exposes the exact same public interface as the UserPreferences class (ideally an object that is a UserPreferences instance), which can fetch the real UserPreferences object from the scoping mechanism (HTTP request, Session, and so forth). The container injects this proxy object into the userManager bean, which is unaware that this UserPreferences reference is a proxy. In this example, when a UserManager instance invokes a method on the dependency-injected UserPreferences object, it is actually invoking a method on the proxy. The proxy then fetches the real UserPreferences object from (in this case) the HTTP Session and delegates the method invocation onto the retrieved real UserPreferences object. Thus, you need the following (correct and complete) configuration when injecting request- and session-scoped beans into collaborating objects, as the following example shows:     Choosing the Type of Proxy to Create By default, when the Spring container creates a proxy for a bean that is marked up with the element, a CGLIB-based class proxy is created. CGLIB proxies intercept only public method calls! Do not call non-public methods  on such a proxy. They are not delegated to the actual scoped target object. Alternatively, you can configure the Spring container to create standard JDK interface-based proxies for such scoped beans, by specifying false for the value of the proxy-target-class attribute of the element. Using JDK interface-based proxies means that you do not need additional libraries in your application classpath to affect such proxying. However, it also means that the class of the scoped bean must implement at least one interface and that all collaborators into which the scoped bean is injected must reference the bean through one of its interfaces. The following example shows a proxy based on an interface:     For more detailed information about choosing class-based or interface-based proxying, see Proxying Mechanisms. Custom Scopes The bean scoping mechanism is extensible. You can define your own scopes or even redefine existing scopes, although the latter is considered bad practice and you cannot override the built-in singleton and prototype scopes. Creating a Custom Scope To integrate your custom scopes into the Spring container, you need to implement the org.springframework.beans.factory.config.Scope interface, which is described in this section. For an idea of how to implement your own scopes, see the Scope implementations that are supplied with the Spring Framework itself and the Scope javadoc, which explains the methods you need to implement in more detail. The Scope interface has four methods to get objects from the scope, remove them from the scope, and let them be destroyed. The session scope implementation, for example, returns the session-scoped bean (if it does not exist, the method returns a new instance of the bean, after having bound it to the session for future reference). The following method returns the object from the underlying scope: Java Object get(String name, ObjectFactory objectFactory) Kotlin fun get(name: String, objectFactory: ObjectFactory<*>): Any The session scope implementation, for example, removes the session-scoped bean from the underlying session. The object should be returned, but you can return null if the object with the specified name is not found. The following method removes the object from the underlying scope: Java Object remove(String name) Kotlin fun remove(name: String): Any The following method registers a callback that the scope should invoke when it is destroyed or when the specified object in the scope is destroyed: Java void registerDestructionCallback(String name, Runnable destructionCallback) Kotlin fun registerDestructionCallback(name: String, destructionCallback: Runnable) See the javadoc or a Spring scope implementation for more information on destruction callbacks. The following method obtains the conversation identifier for the underlying scope: Java String getConversationId() Kotlin fun getConversationId(): String This identifier is different for each scope. For a session scoped implementation, this identifier can be the session identifier. Using a Custom Scope After you write and test one or more custom Scope implementations, you need to make the Spring container aware of your new scopes. The following method is the central method to register a new Scope with the Spring container: Java void registerScope(String scopeName, Scope scope); Kotlin fun registerScope(scopeName: String, scope: Scope) This method is declared on the ConfigurableBeanFactory interface, which is available through the BeanFactory property on most of the concrete ApplicationContext implementations that ship with Spring. The first argument to the registerScope(..) method is the unique name associated with a scope. Examples of such names in the Spring container itself are singleton and prototype. The second argument to the registerScope(..) method is an actual instance of the custom Scope implementation that you wish to register and use. Suppose that you write your custom Scope implementation, and then register it as shown in the next example. The next example uses SimpleThreadScope, which is included with Spring but is not  registered by default. The instructions would be the same for your own custom Scope implementations. Java Scope threadScope = new SimpleThreadScope(); beanFactory.registerScope("thread", threadScope); Kotlin val threadScope = SimpleThreadScope() beanFactory.registerScope("thread", threadScope) You can then create bean definitions that adhere to the scoping rules of your custom Scope, as follows: With a custom Scope implementation, you are not limited to programmatic registration of the scope. You can also do the Scope registration declaratively, by using the CustomScopeConfigurer class, as the following example shows:                                 When you place within a declaration for a FactoryBean  implementation, it is the factory bean itself that is scoped, not the object returned from getObject(). 2.1.6. Customizing the Nature of a Bean The Spring Framework provides a number of interfaces you can use to customize the nature of a bean. This section groups them as follows: • Lifecycle Callbacks • ApplicationContextAware and BeanNameAware • Other Aware Interfaces Lifecycle Callbacks To interact with the container’s management of the bean lifecycle, you can implement the Spring InitializingBean and DisposableBean interfaces. The container calls afterPropertiesSet() for the former and destroy() for the latter to let the bean perform certain actions upon initialization and destruction of your beans. The JSR-250 @PostConstruct and @PreDestroy annotations are generally considered best practice for receiving lifecycle callbacks in a modern Spring application. Using these annotations means that your beans are not coupled to Spring-specific  interfaces. For details, see Using @PostConstruct and @PreDestroy. If you do not want to use the JSR-250 annotations but you still want to remove coupling, consider init-method and destroy-method bean definition metadata. Internally, the Spring Framework uses BeanPostProcessor implementations to process any callback interfaces it can find and call the appropriate methods. If you need custom features or other lifecycle behavior Spring does not by default offer, you can implement a BeanPostProcessor yourself. For more information, see Container Extension Points. In addition to the initialization and destruction callbacks, Spring-managed objects may also implement the Lifecycle interface so that those objects can participate in the startup and shutdown process, as driven by the container’s own lifecycle. The lifecycle callback interfaces are described in this section. Initialization Callbacks The org.springframework.beans.factory.InitializingBean interface lets a bean perform initialization work after the container has set all necessary properties on the bean. The InitializingBean interface specifies a single method: void afterPropertiesSet() throws Exception; We recommend that you do not use the InitializingBean interface, because it unnecessarily couples the code to Spring. Alternatively, we suggest using the @PostConstruct annotation or specifying a POJO initialization method. In the case of XML-based configuration metadata, you can use the init- method attribute to specify the name of the method that has a void no-argument signature. With Java configuration, you can use the initMethod attribute of @Bean. See Receiving Lifecycle Callbacks. Consider the following example: Java public class ExampleBean {   public void init() {   // do some initialization work   } } Kotlin class ExampleBean {   fun init() {   // do some initialization work   } } The preceding example has almost exactly the same effect as the following example (which consists of two listings): Java public class AnotherExampleBean implements InitializingBean {   @Override   public void afterPropertiesSet() {   // do some initialization work   } } Kotlin class AnotherExampleBean : InitializingBean {   override fun afterPropertiesSet() {   // do some initialization work   } } However, the first of the two preceding examples does not couple the code to Spring. Destruction Callbacks Implementing the org.springframework.beans.factory.DisposableBean interface lets a bean get a callback when the container that contains it is destroyed. The DisposableBean interface specifies a single method: void destroy() throws Exception; We recommend that you do not use the DisposableBean callback interface, because it unnecessarily couples the code to Spring. Alternatively, we suggest using the @PreDestroy annotation or specifying a generic method that is supported by bean definitions. With XML-based configuration metadata, you can use the destroy-method attribute on the . With Java configuration, you can use the destroyMethod attribute of @Bean. See Receiving Lifecycle Callbacks. Consider the following definition: Java public class ExampleBean {   public void cleanup() {   // do some destruction work (like releasing pooled connections)   } } Kotlin class ExampleBean {   fun cleanup() {   // do some destruction work (like releasing pooled connections)   } } The preceding definition has almost exactly the same effect as the following definition: Java public class AnotherExampleBean implements DisposableBean {   @Override   public void destroy() {   // do some destruction work (like releasing pooled connections)   } } Kotlin class AnotherExampleBean : DisposableBean {   override fun destroy() {   // do some destruction work (like releasing pooled connections)   } } However, the first of the two preceding definitions does not couple the code to Spring. You can assign the destroy-method attribute of a element a special (inferred) value, which instructs Spring to automatically detect a public close or shutdown method on the specific bean class. (Any class that implements java.lang.AutoCloseable or java.io.Closeable would therefore match.) You can  also set this special (inferred) value on the default-destroy-method attribute of a element to apply this behavior to an entire set of beans (see Default Initialization and Destroy Methods). Note that this is the default behavior with Java configuration. Default Initialization and Destroy Methods When you write initialization and destroy method callbacks that do not use the Spring-specific InitializingBean and DisposableBean callback interfaces, you typically write methods with names such as init(), initialize(), dispose(), and so on. Ideally, the names of such lifecycle callback methods are standardized across a project so that all developers use the same method names and ensure consistency. You can configure the Spring container to “look” for named initialization and destroy callback method names on every bean. This means that you, as an application developer, can write your application classes and use an initialization callback called init(), without having to configure an init-method="init" attribute with each bean definition. The Spring IoC container calls that method when the bean is created (and in accordance with the standard lifecycle callback contract described previously). This feature also enforces a consistent naming convention for initialization and destroy method callbacks. Suppose that your initialization callback methods are named init() and your destroy callback methods are named destroy(). Your class then resembles the class in the following example: Java public class DefaultBlogService implements BlogService {   private BlogDao blogDao;   public void setBlogDao(BlogDao blogDao) {   this.blogDao = blogDao;   }   // this is (unsurprisingly) the initialization callback method   public void init() {   if (this.blogDao == null) {   throw new IllegalStateException("The [blogDao] property must be set.");   }   } } Kotlin class DefaultBlogService : BlogService {   private var blogDao: BlogDao? = null   // this is (unsurprisingly) the initialization callback method   fun init() {   if (blogDao == null) {   throw IllegalStateException("The [blogDao] property must be set.")   }   } } You could then use that class in a bean resembling the following:       The presence of the default-init-method attribute on the top-level element attribute causes the Spring IoC container to recognize a method called init on the bean class as the initialization method callback. When a bean is created and assembled, if the bean class has such a method, it is invoked at the appropriate time. You can configure destroy method callbacks similarly (in XML, that is) by using the default- destroy-method attribute on the top-level element. Where existing bean classes already have callback methods that are named at variance with the convention, you can override the default by specifying (in XML, that is) the method name by using the init-method and destroy-method attributes of the itself. The Spring container guarantees that a configured initialization callback is called immediately after a bean is supplied with all dependencies. Thus, the initialization callback is called on the raw bean reference, which means that AOP interceptors and so forth are not yet applied to the bean. A target bean is fully created first and then an AOP proxy (for example) with its interceptor chain is applied. If the target bean and the proxy are defined separately, your code can even interact with the raw target bean, bypassing the proxy. Hence, it would be inconsistent to apply the interceptors to the init method, because doing so would couple the lifecycle of the target bean to its proxy or interceptors and leave strange semantics when your code interacts directly with the raw target bean. ================================================ FILE: models/spring-ai-postgresml/README.md ================================================ [PostgresML Embedding Documentation](https://docs.spring.io/spring-ai/reference/api/embeddings/postgresml-embeddings.html) ================================================ FILE: models/spring-ai-postgresml/pom.xml ================================================ 4.0.0 org.springframework.ai spring-ai-parent 2.0.0-SNAPSHOT ../../pom.xml spring-ai-postgresml jar Spring AI Model - PostgresML PostgresML models support https://github.com/spring-projects/spring-ai https://github.com/spring-projects/spring-ai scm:git:git://github.com/spring-projects/spring-ai.git scm:git:ssh://git@github.com/spring-projects/spring-ai.git org.springframework.ai spring-ai-model ${project.parent.version} org.postgresql postgresql runtime org.springframework.boot spring-boot-starter-jdbc org.springframework spring-jdbc org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-starter-jdbc-test test org.springframework.boot spring-boot-testcontainers test org.testcontainers testcontainers-junit-jupiter test org.testcontainers testcontainers-postgresql test com.zaxxer HikariCP test ================================================ FILE: models/spring-ai-postgresml/src/main/java/org/springframework/ai/postgresml/PostgresMlEmbeddingModel.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License");

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. --- ## Solution: Parallel Streaming with Deferred Recursion The solution uses `publish()` to multicast the stream, enabling parallel streaming and aggregation: ``` Model Stream ──► publish() ──┬──► streamingBranch ──► emit chunks immediately │ └──► aggregation ──► detect tool calls ──► recurse if needed ``` ### Implementation The `internalStream` method handles each iteration: ```java private Flux internalStream(StreamAdvisorChain streamAdvisorChain, ChatClientRequest originalRequest, ToolCallingChatOptions optionsCopy, List instructions) { return Flux.deferContextual(contextView -> { var processedRequest = ChatClientRequest.builder() .prompt(new Prompt(instructions, optionsCopy)) .context(originalRequest.context()) .build(); processedRequest = this.doBeforeStream(processedRequest, streamAdvisorChain); Flux responseFlux = streamAdvisorChain.copy(this).nextStream(processedRequest); AtomicReference aggregatedResponseRef = new AtomicReference<>(); return streamWithToolCallResponses(responseFlux, aggregatedResponseRef, processedRequest, streamAdvisorChain, originalRequest, optionsCopy); }); } ``` The `streamWithToolCallResponses` method uses `publish()` for parallel processing: ```java private Flux streamWithToolCallResponses(Flux responseFlux, AtomicReference aggregatedResponseRef, ChatClientRequest finalRequest, StreamAdvisorChain streamAdvisorChain, ChatClientRequest originalRequest, ToolCallingChatOptions optionsCopy) { return responseFlux.publish(shared -> { // Branch 1: Stream chunks immediately for real-time UX Flux streamingBranch = new ChatClientMessageAggregator() .aggregateChatClientResponse(shared, aggregatedResponseRef::set); // Branch 2: After streaming completes, check for tool calls and recurse Flux recursionBranch = Flux .defer(() -> handleToolCallRecursion(aggregatedResponseRef.get(), finalRequest, streamAdvisorChain, originalRequest, optionsCopy)); return streamingBranch.concatWith(recursionBranch); }) .filter(ccr -> this.streamToolCallResponses || !(ccr.chatResponse() != null && ccr.chatResponse().hasToolCalls())); } ``` ### How It Works **For a tool call iteration:** ``` Model emits: [chunk1] [chunk2] [chunk3:tool_call] [complete] │ │ │ │ Streaming: emit emit emit │ ◄── Real-time to downstream │ Aggregation: ─────────────────────────────────► complete │ ▼ detect tool call → execute → recurse ``` **For the final answer:** ``` Model emits: [chunk1] [chunk2] ... [chunkN] [complete] │ │ │ │ Streaming: emit emit emit │ ◄── Real-time to downstream │ Aggregation: ───────────────────────────► complete │ ▼ no tool call → done ``` --- ## Configuration: Filtering Tool Call Responses The `streamToolCallResponses` option controls whether intermediate tool call responses are emitted downstream: ```java // Default: Only stream final answer (tool call responses filtered out) ToolCallAdvisor advisor = ToolCallAdvisor.builder().build(); // Stream all chunks including intermediate tool calls ToolCallAdvisor advisor = ToolCallAdvisor.builder() .streamToolCallResponses(true) .build(); ``` | Configuration | Intermediate Tool Calls | Final Answer | |--------------|------------------------|--------------| | `streamToolCallResponses(false)` (default) | Filtered out | Streamed | | `streamToolCallResponses(true)` | Streamed | Streamed | The filtering is implemented as a terminal filter on the stream: ```java .filter(ccr -> this.streamToolCallResponses || !(ccr.chatResponse() != null && ccr.chatResponse().hasToolCalls())) ``` ### Use Cases - **API backend**: Use default to only receive the final answer - **Chat UI with progress feedback**: Use `streamToolCallResponses(true)` to show tool execution in real-time - **Debugging**: Use `streamToolCallResponses(true)` to see all intermediate responses --- ## Key Benefits 1. **Real-time streaming**: Chunks are emitted immediately as they arrive 2. **Correct tool call detection**: Based on aggregated response, not individual chunks 3. **Memory consistency**: Aggregation completes before recursion, ensuring proper sequencing 4. **Configurable output**: Filter intermediate tool calls based on use case 5. **Simple implementation**: Single code path with terminal filter ================================================ FILE: spring-ai-client-chat/src/main/java/org/springframework/ai/chat/client/advisor/ToolCallAdvisor.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * https://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ package org.springframework.ai.chat.client.advisor; import java.util.List; import java.util.concurrent.atomic.AtomicReference; import reactor.core.publisher.Flux; import reactor.core.scheduler.Schedulers; import org.springframework.ai.chat.client.ChatClientMessageAggregator; import org.springframework.ai.chat.client.ChatClientRequest; import org.springframework.ai.chat.client.ChatClientResponse; import org.springframework.ai.chat.client.advisor.api.BaseAdvisor; import org.springframework.ai.chat.client.advisor.api.CallAdvisor; import org.springframework.ai.chat.client.advisor.api.CallAdvisorChain; import org.springframework.ai.chat.client.advisor.api.StreamAdvisor; import org.springframework.ai.chat.client.advisor.api.StreamAdvisorChain; import org.springframework.ai.chat.messages.Message; import org.springframework.ai.chat.model.ChatResponse; import org.springframework.ai.chat.prompt.Prompt; import org.springframework.ai.model.tool.ToolCallingChatOptions; import org.springframework.ai.model.tool.ToolCallingManager; import org.springframework.ai.model.tool.ToolExecutionResult; import org.springframework.ai.model.tool.internal.ToolCallReactiveContextHolder; import org.springframework.core.Ordered; import org.springframework.util.Assert; /** * Recursive Advisor that disables the internal tool execution flow and instead implements * the tool calling loop as part of the advisor chain. *

* This evaluator addresses a specific type of potential error in LLM outputs known as * "hallucination" in the context of grounded factuality. It verifies whether a given * statement (the "claim") is logically supported by a provided context (the "document"). *

* Key concepts: - Document: The context or grounding information against which the claim * is checked. - Claim: The statement to be verified against the document. *

* The evaluator uses a prompt-based approach with a separate, typically smaller and more * efficient LLM to perform the fact-checking. This design choice allows for * cost-effective and rapid verification, which is crucial when evaluating longer LLM * outputs that may require multiple verification steps. *

* Implementation note: For efficient and accurate fact-checking, consider using * specialized models like Bespoke-Minicheck, a grounded factuality checking model * developed by Bespoke Labs and available in Ollama. Such models are specifically * designed to fact-check responses generated by other models, helping to detect and * reduce hallucinations. For more information, see: * Reduce * Hallucinations with Bespoke-Minicheck and the research paper: * MiniCheck: An Efficient Method for LLM * Hallucination Detection *

* Note: This evaluator is specifically designed to fact-check statements against given * information. It's not meant for other types of accuracy tests, like quizzing an AI on * obscure facts without giving it any reference material to work with (so-called 'closed * book' scenarios). *

Spring Framework Overview Spring makes it easy to create Java enterprise applications. It provides everything you need to embrace the Java language in an enterprise environment, with support for Groovy and Kotlin as alternative languages on the JVM, and with the flexibility to create many kinds of architectures depending on an application’s needs. As of Spring Framework 5.1, Spring requires JDK 8+ (Java SE 8+) and provides out-of-the-box support for JDK 11 LTS. Java SE 8 update 60 is suggested as the minimum patch release for Java 8, but it is generally recommended to use a recent patch release. Spring supports a wide range of application scenarios. In a large enterprise, applications often exist for a long time and have to run on a JDK and application server whose upgrade cycle is beyond developer control. Others may run as a single jar with the server embedded, possibly in a cloud environment. Yet others may be standalone applications (such as batch or integration workloads) that do not need a server. Spring is open source. It has a large and active community that provides continuous feedback based on a diverse range of real-world use cases. This has helped Spring to successfully evolve over a very long time. 1.1. What We Mean by "Spring" The term "Spring" means different things in different contexts. It can be used to refer to the Spring Framework project itself, which is where it all started. Over time, other Spring projects have been built on top of the Spring Framework. Most often, when people say "Spring", they mean the entire family of projects. This reference documentation focuses on the foundation: the Spring Framework itself. The Spring Framework is divided into modules. Applications can choose which modules they need. At the heart are the modules of the core container, including a configuration model and a dependency injection mechanism. Beyond that, the Spring Framework provides foundational support for different application architectures, including messaging, transactional data and persistence, and web. It also includes the Servlet-based Spring MVC web framework and, in parallel, the Spring WebFlux reactive web framework. A note about modules: Spring’s framework jars allow for deployment to JDK 9’s module path ("Jigsaw"). For use in Jigsaw-enabled applications, the Spring Framework 5 jars come with "Automatic-Module-Name" manifest entries which define stable language-level module names ("spring.core", "spring.context", etc.) independent from jar artifact names (the jars follow the same naming pattern with "-" instead of ".", e.g. "spring-core" and "spring-context"). Of course, Spring’s framework jars keep working fine on the classpath on both JDK 8 and 9+. 1.2. History of Spring and the Spring Framework Spring came into being in 2003 as a response to the complexity of the early J2EE specifications. While some consider Java EE and its modern-day successor Jakarta EE to be in competition with Spring, they are in fact complementary. The Spring programming model does not embrace the Jakarta EE platform specification; rather, it integrates with carefully selected individual specifications from the traditional EE umbrella: • Servlet API (JSR 340) • WebSocket API (JSR 356) • Concurrency Utilities (JSR 236) • JSON Binding API (JSR 367) • Bean Validation (JSR 303) • JPA (JSR 338) • JMS (JSR 914) • as well as JTA/JCA setups for transaction coordination, if necessary. The Spring Framework also supports the Dependency Injection (JSR 330) and Common Annotations (JSR 250) specifications, which application developers may choose to use instead of the Spring- specific mechanisms provided by the Spring Framework. Originally, those were based on common javax packages. As of Spring Framework 6.0, Spring has been upgraded to the Jakarta EE 9 level (e.g. Servlet 5.0+, JPA 3.0+), based on the jakarta namespace instead of the traditional javax packages. With EE 9 as the minimum and EE 10 supported already, Spring is prepared to provide out-of-the-box support for the further evolution of the Jakarta EE APIs. Spring Framework 6.0 is fully compatible with Tomcat 10.1, Jetty 11 and Undertow 2.3 as web servers, and also with Hibernate ORM 6.1. Over time, the role of Java/Jakarta EE in application development has evolved. In the early days of J2EE and Spring, applications were created to be deployed to an application server. Today, with the help of Spring Boot, applications are created in a devops- and cloud-friendly way, with the Servlet container embedded and trivial to change. As of Spring Framework 5, a WebFlux application does not even use the Servlet API directly and can run on servers (such as Netty) that are not Servlet containers. Spring continues to innovate and to evolve. Beyond the Spring Framework, there are other projects, such as Spring Boot, Spring Security, Spring Data, Spring Cloud, Spring Batch, among others. It’s important to remember that each project has its own source code repository, issue tracker, and release cadence. See spring.io/projects for the complete list of Spring projects. 1.3. Design Philosophy When you learn about a framework, it’s important to know not only what it does but what principles it follows. Here are the guiding principles of the Spring Framework: • Provide choice at every level. Spring lets you defer design decisions as late as possible. For example, you can switch persistence providers through configuration without changing your code. The same is true for many other infrastructure concerns and integration with third-party APIs. • Accommodate diverse perspectives. Spring embraces flexibility and is not opinionated about how things should be done. It supports a wide range of application needs with different perspectives. • Maintain strong backward compatibility. Spring’s evolution has been carefully managed to force few breaking changes between versions. Spring supports a carefully chosen range of JDK versions and third-party libraries to facilitate maintenance of applications and libraries that depend on Spring. • Care about API design. The Spring team puts a lot of thought and time into making APIs that are intuitive and that hold up across many versions and many years. • Set high standards for code quality. The Spring Framework puts a strong emphasis on meaningful, current, and accurate javadoc. It is one of very few projects that can claim clean code structure with no circular dependencies between packages. 1.4. Feedback and Contributions For how-to questions or diagnosing or debugging issues, we suggest using Stack Overflow. Click here for a list of the suggested tags to use on Stack Overflow. If you’re fairly certain that there is a problem in the Spring Framework or would like to suggest a feature, please use the GitHub Issues. If you have a solution in mind or a suggested fix, you can submit a pull request on Github. However, please keep in mind that, for all but the most trivial issues, we expect a ticket to be filed in the issue tracker, where discussions take place and leave a record for future reference. For more details see the guidelines at the CONTRIBUTING, top-level project page. 1.5. Getting Started If you are just getting started with Spring, you may want to begin using the Spring Framework by creating a Spring Boot-based application. Spring Boot provides a quick (and opinionated) way to create a production-ready Spring-based application. It is based on the Spring Framework, favors convention over configuration, and is designed to get you up and running as quickly as possible. You can use start.spring.io to generate a basic project or follow one of the "Getting Started" guides, such as Getting Started Building a RESTful Web Service. As well as being easier to digest, these guides are very task focused, and most of them are based on Spring Boot. They also cover other projects from the Spring portfolio that you might want to consider when solving a particular problem. Chapter 2. Core Technologies This part of the reference documentation covers all the technologies that are absolutely integral to the Spring Framework. Foremost amongst these is the Spring Framework’s Inversion of Control (IoC) container. A thorough treatment of the Spring Framework’s IoC container is closely followed by comprehensive coverage of Spring’s Aspect-Oriented Programming (AOP) technologies. The Spring Framework has its own AOP framework, which is conceptually easy to understand and which successfully addresses the 80% sweet spot of AOP requirements in Java enterprise programming. Coverage of Spring’s integration with AspectJ (currently the richest — in terms of features — and certainly most mature AOP implementation in the Java enterprise space) is also provided. AOT processing can be used to optimize your application ahead-of-time. It is typically used for native image deployment using GraalVM. 2.1. The IoC Container This chapter covers Spring’s Inversion of Control (IoC) container. 2.1.1. Introduction to the Spring IoC Container and Beans This chapter covers the Spring Framework implementation of the Inversion of Control (IoC) principle. IoC is also known as dependency injection (DI). It is a process whereby objects define their dependencies (that is, the other objects they work with) only through constructor arguments, arguments to a factory method, or properties that are set on the object instance after it is constructed or returned from a factory method. The container then injects those dependencies when it creates the bean. This process is fundamentally the inverse (hence the name, Inversion of Control) of the bean itself controlling the instantiation or location of its dependencies by using direct construction of classes or a mechanism such as the Service Locator pattern. The org.springframework.beans and org.springframework.context packages are the basis for Spring Framework’s IoC container. The BeanFactory interface provides an advanced configuration mechanism capable of managing any type of object. ApplicationContext is a sub-interface of BeanFactory. It adds: • Easier integration with Spring’s AOP features • Message resource handling (for use in internationalization) • Event publication • Application-layer specific contexts such as the WebApplicationContext for use in web applications. In short, the BeanFactory provides the configuration framework and basic functionality, and the ApplicationContext adds more enterprise-specific functionality. The ApplicationContext is a complete superset of the BeanFactory and is used exclusively in this chapter in descriptions of Spring’s IoC container. For more information on using the BeanFactory instead of the ApplicationContext, see the section covering the BeanFactory API. In Spring, the objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your application. Beans, and the dependencies among them, are reflected in the configuration metadata used by a container. 2.1.2. Container Overview The org.springframework.context.ApplicationContext interface represents the Spring IoC container and is responsible for instantiating, configuring, and assembling the beans. The container gets its instructions on what objects to instantiate, configure, and assemble by reading configuration metadata. The configuration metadata is represented in XML, Java annotations, or Java code. It lets you express the objects that compose your application and the rich interdependencies between those objects. Several implementations of the ApplicationContext interface are supplied with Spring. In stand- alone applications, it is common to create an instance of ClassPathXmlApplicationContext or FileSystemXmlApplicationContext. While XML has been the traditional format for defining configuration metadata, you can instruct the container to use Java annotations or code as the metadata format by providing a small amount of XML configuration to declaratively enable support for these additional metadata formats. In most application scenarios, explicit user code is not required to instantiate one or more instances of a Spring IoC container. For example, in a web application scenario, a simple eight (or so) lines of boilerplate web descriptor XML in the web.xml file of the application typically suffices (see Convenient ApplicationContext Instantiation for Web Applications). If you use the Spring Tools for Eclipse (an Eclipse-powered development environment), you can easily create this boilerplate configuration with a few mouse clicks or keystrokes. The following diagram shows a high-level view of how Spring works. Your application classes are combined with configuration metadata so that, after the ApplicationContext is created and initialized, you have a fully configured and executable system or application. Figure 1. The Spring IoC container Configuration Metadata As the preceding diagram shows, the Spring IoC container consumes a form of configuration metadata. This configuration metadata represents how you, as an application developer, tell the Spring container to instantiate, configure, and assemble the objects in your application. Configuration metadata is traditionally supplied in a simple and intuitive XML format, which is what most of this chapter uses to convey key concepts and features of the Spring IoC container. XML-based metadata is not the only allowed form of configuration metadata. The Spring IoC container itself is totally decoupled from the format in which this  configuration metadata is actually written. These days, many developers choose Java-based configuration for their Spring applications. For information about using other forms of metadata with the Spring container, see: • Annotation-based configuration: Spring 2.5 introduced support for annotation-based configuration metadata. • Java-based configuration: Starting with Spring 3.0, many features provided by the Spring JavaConfig project became part of the core Spring Framework. Thus, you can define beans external to your application classes by using Java rather than XML files. To use these new features, see the @Configuration, @Bean, @Import, and @DependsOn annotations. Spring configuration consists of at least one and typically more than one bean definition that the container must manage. XML-based configuration metadata configures these beans as elements inside a top-level element. Java configuration typically uses @Bean-annotated methods within a @Configuration class. These bean definitions correspond to the actual objects that make up your application. Typically, you define service layer objects, data access objects (DAOs), presentation objects such as Struts Action instances, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so forth. Typically, one does not configure fine-grained domain objects in the container, because it is usually the responsibility of DAOs and business logic to create and load domain objects. However, you can use Spring’s integration with AspectJ to configure objects that have been created outside the control of an IoC container. See Using AspectJ to dependency-inject domain objects with Spring. The following example shows the basic structure of XML-based configuration metadata:   ① ②             ① The id attribute is a string that identifies the individual bean definition. ② The class attribute defines the type of the bean and uses the fully qualified classname. The value of the id attribute refers to collaborating objects. The XML for referring to collaborating objects is not shown in this example. See Dependencies for more information. Instantiating a Container The location path or paths supplied to an ApplicationContext constructor are resource strings that let the container load configuration metadata from a variety of external resources, such as the local file system, the Java CLASSPATH, and so on. Java ApplicationContext context = new ClassPathXmlApplicationContext("services.xml", "daos.xml"); Kotlin val context = ClassPathXmlApplicationContext("services.xml", "daos.xml") After you learn about Spring’s IoC container, you may want to know more about Spring’s Resource abstraction (as described in Resources), which provides a  convenient mechanism for reading an InputStream from locations defined in a URI syntax. In particular, Resource paths are used to construct applications contexts, as described in Application Contexts and Resource Paths. The following example shows the service layer objects (services.xml) configuration file:               The following example shows the data access objects daos.xml file:               In the preceding example, the service layer consists of the PetStoreServiceImpl class and two data access objects of the types JpaAccountDao and JpaItemDao (based on the JPA Object-Relational Mapping standard). The property name element refers to the name of the JavaBean property, and the ref element refers to the name of another bean definition. This linkage between id and ref elements expresses the dependency between collaborating objects. For details of configuring an object’s dependencies, see Dependencies. Composing XML-based Configuration Metadata It can be useful to have bean definitions span multiple XML files. Often, each individual XML configuration file represents a logical layer or module in your architecture. You can use the application context constructor to load bean definitions from all these XML fragments. This constructor takes multiple Resource locations, as was shown in the previous section. Alternatively, use one or more occurrences of the element to load bean definitions from another file or files. The following example shows how to do so:           In the preceding example, external bean definitions are loaded from three files: services.xml, messageSource.xml, and themeSource.xml. All location paths are relative to the definition file doing the importing, so services.xml must be in the same directory or classpath location as the file doing the importing, while messageSource.xml and themeSource.xml must be in a resources location below the location of the importing file. As you can see, a leading slash is ignored. However, given that these paths are relative, it is better form not to use the slash at all. The contents of the files being imported, including the top level element, must be valid XML bean definitions, according to the Spring Schema. It is possible, but not recommended, to reference files in parent directories using a relative "../" path. Doing so creates a dependency on a file that is outside the current application. In particular, this reference is not recommended for classpath: URLs (for example, classpath:../services.xml), where the runtime resolution process chooses the “nearest” classpath root and then looks into its parent directory. Classpath configuration changes may lead to the choice of a different, incorrect directory.  You can always use fully qualified resource locations instead of relative paths: for example, file:C:/config/services.xml or classpath:/config/services.xml. However, be aware that you are coupling your application’s configuration to specific absolute locations. It is generally preferable to keep an indirection for such absolute locations — for example, through "${…}" placeholders that are resolved against JVM system properties at runtime. The namespace itself provides the import directive feature. Further configuration features beyond plain bean definitions are available in a selection of XML namespaces provided by Spring — for example, the context and util namespaces. The Groovy Bean Definition DSL As a further example for externalized configuration metadata, bean definitions can also be expressed in Spring’s Groovy Bean Definition DSL, as known from the Grails framework. Typically, such configuration live in a ".groovy" file with the structure shown in the following example: beans {   dataSource(BasicDataSource) {   driverClassName = "org.hsqldb.jdbcDriver"   url = "jdbc:hsqldb:mem:grailsDB"   username = "sa"   password = ""   settings = [mynew:"setting"]   }   sessionFactory(SessionFactory) {   dataSource = dataSource   }   myService(MyService) {   nestedBean = { AnotherBean bean ->   dataSource = dataSource   }   } } This configuration style is largely equivalent to XML bean definitions and even supports Spring’s XML configuration namespaces. It also allows for importing XML bean definition files through an importBeans directive. Using the Container The ApplicationContext is the interface for an advanced factory capable of maintaining a registry of different beans and their dependencies. By using the method T getBean(String name, Class requiredType), you can retrieve instances of your beans. The ApplicationContext lets you read bean definitions and access them, as the following example shows: Java // create and configure beans ApplicationContext context = new ClassPathXmlApplicationContext("services.xml", "daos.xml"); // retrieve configured instance PetStoreService service = context.getBean("petStore", PetStoreService.class); // use configured instance List userList = service.getUsernameList(); Kotlin import org.springframework.beans.factory.getBean // create and configure beans val context = ClassPathXmlApplicationContext("services.xml", "daos.xml") // retrieve configured instance val service = context.getBean("petStore") // use configured instance var userList = service.getUsernameList() With Groovy configuration, bootstrapping looks very similar. It has a different context implementation class which is Groovy-aware (but also understands XML bean definitions). The following example shows Groovy configuration: Java ApplicationContext context = new GenericGroovyApplicationContext("services.groovy", "daos.groovy"); Kotlin val context = GenericGroovyApplicationContext("services.groovy", "daos.groovy") The most flexible variant is GenericApplicationContext in combination with reader delegates — for example, with XmlBeanDefinitionReader for XML files, as the following example shows: Java GenericApplicationContext context = new GenericApplicationContext(); new XmlBeanDefinitionReader(context).loadBeanDefinitions("services.xml", "daos.xml"); context.refresh(); Kotlin val context = GenericApplicationContext() XmlBeanDefinitionReader(context).loadBeanDefinitions("services.xml", "daos.xml") context.refresh() You can also use the GroovyBeanDefinitionReader for Groovy files, as the following example shows: Java GenericApplicationContext context = new GenericApplicationContext(); new GroovyBeanDefinitionReader(context).loadBeanDefinitions("services.groovy", "daos.groovy"); context.refresh(); Kotlin val context = GenericApplicationContext() GroovyBeanDefinitionReader(context).loadBeanDefinitions("services.groovy", "daos.groovy") context.refresh() You can mix and match such reader delegates on the same ApplicationContext, reading bean definitions from diverse configuration sources. You can then use getBean to retrieve instances of your beans. The ApplicationContext interface has a few other methods for retrieving beans, but, ideally, your application code should never use them. Indeed, your application code should have no calls to the getBean() method at all and thus have no dependency on Spring APIs at all. For example, Spring’s integration with web frameworks provides dependency injection for various web framework components such as controllers and JSF-managed beans, letting you declare a dependency on a specific bean through metadata (such as an autowiring annotation). 2.1.3. Bean Overview A Spring IoC container manages one or more beans. These beans are created with the configuration metadata that you supply to the container (for example, in the form of XML definitions). Within the container itself, these bean definitions are represented as BeanDefinition objects, which contain (among other information) the following metadata: • A package-qualified class name: typically, the actual implementation class of the bean being defined. • Bean behavioral configuration elements, which state how the bean should behave in the container (scope, lifecycle callbacks, and so forth). • References to other beans that are needed for the bean to do its work. These references are also called collaborators or dependencies. • Other configuration settings to set in the newly created object — for example, the size limit of the pool or the number of connections to use in a bean that manages a connection pool. This metadata translates to a set of properties that make up each bean definition. The following table describes these properties: Table 1. The bean definition Property Explained in… Class Instantiating Beans Name Naming Beans Scope Bean Scopes Constructor arguments Dependency Injection Properties Dependency Injection Autowiring mode Autowiring Collaborators Lazy initialization mode Lazy-initialized Beans Initialization method Initialization Callbacks Destruction method Destruction Callbacks In addition to bean definitions that contain information on how to create a specific bean, the ApplicationContext implementations also permit the registration of existing objects that are created outside the container (by users). This is done by accessing the ApplicationContext’s BeanFactory through the getBeanFactory() method, which returns the DefaultListableBeanFactory implementation. DefaultListableBeanFactory supports this registration through the registerSingleton(..) and registerBeanDefinition(..) methods. However, typical applications work solely with beans defined through regular bean definition metadata. Bean metadata and manually supplied singleton instances need to be registered as early as possible, in order for the container to properly reason about them during autowiring and other introspection steps. While overriding existing metadata and  existing singleton instances is supported to some degree, the registration of new beans at runtime (concurrently with live access to the factory) is not officially supported and may lead to concurrent access exceptions, inconsistent state in the bean container, or both. Naming Beans Every bean has one or more identifiers. These identifiers must be unique within the container that hosts the bean. A bean usually has only one identifier. However, if it requires more than one, the extra ones can be considered aliases. In XML-based configuration metadata, you use the id attribute, the name attribute, or both to specify the bean identifiers. The id attribute lets you specify exactly one id. Conventionally, these names are alphanumeric ('myBean', 'someService', etc.), but they can contain special characters as well. If you want to introduce other aliases for the bean, you can also specify them in the name attribute, separated by a comma (,), semicolon (;), or white space. As a historical note, in versions prior to Spring 3.1, the id attribute was defined as an xsd:ID type, which constrained possible characters. As of 3.1, it is defined as an xsd:string type. Note that bean id uniqueness is still enforced by the container, though no longer by XML parsers. You are not required to supply a name or an id for a bean. If you do not supply a name or id explicitly, the container generates a unique name for that bean. However, if you want to refer to that bean by name, through the use of the ref element or a Service Locator style lookup, you must provide a name. Motivations for not supplying a name are related to using inner beans and autowiring collaborators. Bean Naming Conventions The convention is to use the standard Java convention for instance field names when naming beans. That is, bean names start with a lowercase letter and are camel-cased from there. Examples of such names include accountManager, accountService, userDao, loginController, and so forth. Naming beans consistently makes your configuration easier to read and understand. Also, if you use Spring AOP, it helps a lot when applying advice to a set of beans related by name. With component scanning in the classpath, Spring generates bean names for unnamed components, following the rules described earlier: essentially, taking the simple class name and turning its initial character to lower-case. However, in the  (unusual) special case when there is more than one character and both the first and second characters are upper case, the original casing gets preserved. These are the same rules as defined by java.beans.Introspector.decapitalize (which Spring uses here). Aliasing a Bean outside the Bean Definition In a bean definition itself, you can supply more than one name for the bean, by using a combination of up to one name specified by the id attribute and any number of other names in the name attribute. These names can be equivalent aliases to the same bean and are useful for some situations, such as letting each component in an application refer to a common dependency by using a bean name that is specific to that component itself. Specifying all aliases where the bean is actually defined is not always adequate, however. It is sometimes desirable to introduce an alias for a bean that is defined elsewhere. This is commonly the case in large systems where configuration is split amongst each subsystem, with each subsystem having its own set of object definitions. In XML-based configuration metadata, you can use the element to accomplish this. The following example shows how to do so: In this case, a bean (in the same container) named fromName may also, after the use of this alias definition, be referred to as toName. For example, the configuration metadata for subsystem A may refer to a DataSource by the name of subsystemA-dataSource. The configuration metadata for subsystem B may refer to a DataSource by the name of subsystemB-dataSource. When composing the main application that uses both these subsystems, the main application refers to the DataSource by the name of myApp-dataSource. To have all three names refer to the same object, you can add the following alias definitions to the configuration metadata: Now each component and the main application can refer to the dataSource through a name that is unique and guaranteed not to clash with any other definition (effectively creating a namespace), yet they refer to the same bean. Java-configuration If you use Javaconfiguration, the @Bean annotation can be used to provide aliases. See Using the @Bean Annotation for details. Instantiating Beans A bean definition is essentially a recipe for creating one or more objects. The container looks at the recipe for a named bean when asked and uses the configuration metadata encapsulated by that bean definition to create (or acquire) an actual object. If you use XML-based configuration metadata, you specify the type (or class) of object that is to be instantiated in the class attribute of the element. This class attribute (which, internally, is a Class property on a BeanDefinition instance) is usually mandatory. (For exceptions, see Instantiation by Using an Instance Factory Method and Bean Definition Inheritance.) You can use the Class property in one of two ways: • Typically, to specify the bean class to be constructed in the case where the container itself directly creates the bean by calling its constructor reflectively, somewhat equivalent to Java code with the new operator. • To specify the actual class containing the static factory method that is invoked to create the object, in the less common case where the container invokes a static factory method on a class to create the bean. The object type returned from the invocation of the static factory method may be the same class or another class entirely. Nested class names If you want to configure a bean definition for a nested class, you may use either the binary name or the source name of the nested class. For example, if you have a class called SomeThing in the com.example package, and this SomeThing class has a static nested class called OtherThing, they can be separated by a dollar sign ($) or a dot (.). So the value of the class attribute in a bean definition would be com.example.SomeThing$OtherThing or com.example.SomeThing.OtherThing. Instantiation with a Constructor When you create a bean by the constructor approach, all normal classes are usable by and compatible with Spring. That is, the class being developed does not need to implement any specific interfaces or to be coded in a specific fashion. Simply specifying the bean class should suffice. However, depending on what type of IoC you use for that specific bean, you may need a default (empty) constructor. The Spring IoC container can manage virtually any class you want it to manage. It is not limited to managing true JavaBeans. Most Spring users prefer actual JavaBeans with only a default (no- argument) constructor and appropriate setters and getters modeled after the properties in the container. You can also have more exotic non-bean-style classes in your container. If, for example, you need to use a legacy connection pool that absolutely does not adhere to the JavaBean specification, Spring can manage it as well. With XML-based configuration metadata you can specify your bean class as follows: For details about the mechanism for supplying arguments to the constructor (if required) and setting object instance properties after the object is constructed, see Injecting Dependencies. Instantiation with a Static Factory Method When defining a bean that you create with a static factory method, use the class attribute to specify the class that contains the static factory method and an attribute named factory-method to specify the name of the factory method itself. You should be able to call this method (with optional arguments, as described later) and return a live object, which subsequently is treated as if it had been created through a constructor. One use for such a bean definition is to call static factories in legacy code. The following bean definition specifies that the bean will be created by calling a factory method. The definition does not specify the type (class) of the returned object, but rather the class containing the factory method. In this example, the createInstance() method must be a static method. The following example shows how to specify a factory method: The following example shows a class that would work with the preceding bean definition: Java public class ClientService {   private static ClientService clientService = new ClientService();   private ClientService() {}   public static ClientService createInstance() {   return clientService;   } } Kotlin class ClientService private constructor() {   companion object {   private val clientService = ClientService()   @JvmStatic   fun createInstance() = clientService   } } For details about the mechanism for supplying (optional) arguments to the factory method and setting object instance properties after the object is returned from the factory, see Dependencies and Configuration in Detail. Instantiation by Using an Instance Factory Method Similar to instantiation through a static factory method, instantiation with an instance factory method invokes a non-static method of an existing bean from the container to create a new bean. To use this mechanism, leave the class attribute empty and, in the factory-bean attribute, specify the name of a bean in the current (or parent or ancestor) container that contains the instance method that is to be invoked to create the object. Set the name of the factory method itself with the factory-method attribute. The following example shows how to configure such a bean:   The following example shows the corresponding class: Java public class DefaultServiceLocator {   private static ClientService clientService = new ClientServiceImpl();   public ClientService createClientServiceInstance() {   return clientService;   } } Kotlin class DefaultServiceLocator {   companion object {   private val clientService = ClientServiceImpl()   }   fun createClientServiceInstance(): ClientService {   return clientService   } } One factory class can also hold more than one factory method, as the following example shows:   The following example shows the corresponding class: Java public class DefaultServiceLocator {   private static ClientService clientService = new ClientServiceImpl();   private static AccountService accountService = new AccountServiceImpl();   public ClientService createClientServiceInstance() {   return clientService;   }   public AccountService createAccountServiceInstance() {   return accountService;   } } Kotlin class DefaultServiceLocator {   companion object {   private val clientService = ClientServiceImpl()   private val accountService = AccountServiceImpl()   }   fun createClientServiceInstance(): ClientService {   return clientService   }   fun createAccountServiceInstance(): AccountService {   return accountService   } } This approach shows that the factory bean itself can be managed and configured through dependency injection (DI). See Dependencies and Configuration in Detail. In Spring documentation, "factory bean" refers to a bean that is configured in the Spring container and that creates objects through an instance or static factory  method. By contrast, FactoryBean (notice the capitalization) refers to a Spring- specific FactoryBean implementation class. Determining a Bean’s Runtime Type The runtime type of a specific bean is non-trivial to determine. A specified class in the bean metadata definition is just an initial class reference, potentially combined with a declared factory method or being a FactoryBean class which may lead to a different runtime type of the bean, or not being set at all in case of an instance-level factory method (which is resolved via the specified factory-bean name instead). Additionally, AOP proxying may wrap a bean instance with an interface-based proxy with limited exposure of the target bean’s actual type (just its implemented interfaces). The recommended way to find out about the actual runtime type of a particular bean is a BeanFactory.getType call for the specified bean name. This takes all of the above cases into account and returns the type of object that a BeanFactory.getBean call is going to return for the same bean name. 2.1.4. Dependencies A typical enterprise application does not consist of a single object (or bean in the Spring parlance). Even the simplest application has a few objects that work together to present what the end-user sees as a coherent application. This next section explains how you go from defining a number of bean definitions that stand alone to a fully realized application where objects collaborate to achieve a goal. Dependency Injection Dependency injection (DI) is a process whereby objects define their dependencies (that is, the other objects with which they work) only through constructor arguments, arguments to a factory method, or properties that are set on the object instance after it is constructed or returned from a factory method. The container then injects those dependencies when it creates the bean. This process is fundamentally the inverse (hence the name, Inversion of Control) of the bean itself controlling the instantiation or location of its dependencies on its own by using direct construction of classes or the Service Locator pattern. Code is cleaner with the DI principle, and decoupling is more effective when objects are provided with their dependencies. The object does not look up its dependencies and does not know the location or class of the dependencies. As a result, your classes become easier to test, particularly when the dependencies are on interfaces or abstract base classes, which allow for stub or mock implementations to be used in unit tests. DI exists in two major variants: Constructor-based dependency injection and Setter-based dependency injection. Constructor-based Dependency Injection Constructor-based DI is accomplished by the container invoking a constructor with a number of arguments, each representing a dependency. Calling a static factory method with specific arguments to construct the bean is nearly equivalent, and this discussion treats arguments to a constructor and to a static factory method similarly. The following example shows a class that can only be dependency-injected with constructor injection: Java public class SimpleMovieLister {   // the SimpleMovieLister has a dependency on a MovieFinder   private final MovieFinder movieFinder;   // a constructor so that the Spring container can inject a MovieFinder   public SimpleMovieLister(MovieFinder movieFinder) {   this.movieFinder = movieFinder;   }   // business logic that actually uses the injected MovieFinder is omitted... } Kotlin // a constructor so that the Spring container can inject a MovieFinder class SimpleMovieLister(private val movieFinder: MovieFinder) {   // business logic that actually uses the injected MovieFinder is omitted... } Notice that there is nothing special about this class. It is a POJO that has no dependencies on container specific interfaces, base classes, or annotations. Constructor Argument Resolution Constructor argument resolution matching occurs by using the argument’s type. If no potential ambiguity exists in the constructor arguments of a bean definition, the order in which the constructor arguments are defined in a bean definition is the order in which those arguments are supplied to the appropriate constructor when the bean is being instantiated. Consider the following class: Java package x.y; public class ThingOne {   public ThingOne(ThingTwo thingTwo, ThingThree thingThree) {   // ...   } } Kotlin package x.y class ThingOne(thingTwo: ThingTwo, thingThree: ThingThree) Assuming that the ThingTwo and ThingThree classes are not related by inheritance, no potential ambiguity exists. Thus, the following configuration works fine, and you do not need to specify the constructor argument indexes or types explicitly in the element.             When another bean is referenced, the type is known, and matching can occur (as was the case with the preceding example). When a simple type is used, such as true, Spring cannot determine the type of the value, and so cannot match by type without help. Consider the following class: Java package examples; public class ExampleBean {   // Number of years to calculate the Ultimate Answer   private final int years;   // The Answer to Life, the Universe, and Everything   private final String ultimateAnswer;   public ExampleBean(int years, String ultimateAnswer) {   this.years = years;   this.ultimateAnswer = ultimateAnswer;   } } Kotlin package examples class ExampleBean(   private val years: Int, // Number of years to calculate the Ultimate Answer   private val ultimateAnswer: String // The Answer to Life, the Universe, and Everything ) Constructor argument type matching In the preceding scenario, the container can use type matching with simple types if you explicitly specify the type of the constructor argument by using the type attribute, as the following example shows:     Constructor argument index You can use the index attribute to specify explicitly the index of constructor arguments, as the following example shows:     In addition to resolving the ambiguity of multiple simple values, specifying an index resolves ambiguity where a constructor has two arguments of the same type.  The index is 0-based. Constructor argument name You can also use the constructor parameter name for value disambiguation, as the following example shows:     Keep in mind that, to make this work out of the box, your code must be compiled with the debug flag enabled so that Spring can look up the parameter name from the constructor. If you cannot or do not want to compile your code with the debug flag, you can use the @ConstructorProperties JDK annotation to explicitly name your constructor arguments. The sample class would then have to look as follows: Java package examples; public class ExampleBean {   // Fields omitted   @ConstructorProperties({"years", "ultimateAnswer"})   public ExampleBean(int years, String ultimateAnswer) {   this.years = years;   this.ultimateAnswer = ultimateAnswer;   } } Kotlin package examples class ExampleBean @ConstructorProperties("years", "ultimateAnswer") constructor(val years: Int, val ultimateAnswer: String) Setter-based Dependency Injection Setter-based DI is accomplished by the container calling setter methods on your beans after invoking a no-argument constructor or a no-argument static factory method to instantiate your bean. The following example shows a class that can only be dependency-injected by using pure setter injection. This class is conventional Java. It is a POJO that has no dependencies on container specific interfaces, base classes, or annotations. Java public class SimpleMovieLister {   // the SimpleMovieLister has a dependency on the MovieFinder   private MovieFinder movieFinder;   // a setter method so that the Spring container can inject a MovieFinder   public void setMovieFinder(MovieFinder movieFinder) {   this.movieFinder = movieFinder;   }   // business logic that actually uses the injected MovieFinder is omitted... } Kotlin class SimpleMovieLister {   // a late-initialized property so that the Spring container can inject a MovieFinder   lateinit var movieFinder: MovieFinder   // business logic that actually uses the injected MovieFinder is omitted... } The ApplicationContext supports constructor-based and setter-based DI for the beans it manages. It also supports setter-based DI after some dependencies have already been injected through the constructor approach. You configure the dependencies in the form of a BeanDefinition, which you use in conjunction with PropertyEditor instances to convert properties from one format to another. However, most Spring users do not work with these classes directly (that is, programmatically) but rather with XML bean definitions, annotated components (that is, classes annotated with @Component, @Controller, and so forth), or @Bean methods in Java-based @Configuration classes. These sources are then converted internally into instances of BeanDefinition and used to load an entire Spring IoC container instance. Constructor-based or setter-based DI? Since you can mix constructor-based and setter-based DI, it is a good rule of thumb to use constructors for mandatory dependencies and setter methods or configuration methods for optional dependencies. Note that use of the @Autowired annotation on a setter method can be used to make the property be a required dependency; however, constructor injection with programmatic validation of arguments is preferable. The Spring team generally advocates constructor injection, as it lets you implement application components as immutable objects and ensures that required dependencies are not null. Furthermore, constructor-injected components are always returned to the client (calling) code in a fully initialized state. As a side note, a large number of constructor arguments is a bad code smell, implying that the class likely has too many responsibilities and should be refactored to better address proper separation of concerns. Setter injection should primarily only be used for optional dependencies that can be assigned reasonable default values within the class. Otherwise, not-null checks must be performed everywhere the code uses the dependency. One benefit of setter injection is that setter methods make objects of that class amenable to reconfiguration or re-injection later. Management through JMX MBeans is therefore a compelling use case for setter injection. Use the DI style that makes the most sense for a particular class. Sometimes, when dealing with third-party classes for which you do not have the source, the choice is made for you. For example, if a third-party class does not expose any setter methods, then constructor injection may be the only available form of DI. Dependency Resolution Process The container performs bean dependency resolution as follows: • The ApplicationContext is created and initialized with configuration metadata that describes all the beans. Configuration metadata can be specified by XML, Java code, or annotations. • For each bean, its dependencies are expressed in the form of properties, constructor arguments, or arguments to the static-factory method (if you use that instead of a normal constructor). These dependencies are provided to the bean, when the bean is actually created. • Each property or constructor argument is an actual definition of the value to set, or a reference to another bean in the container. • Each property or constructor argument that is a value is converted from its specified format to the actual type of that property or constructor argument. By default, Spring can convert a value supplied in string format to all built-in types, such as int, long, String, boolean, and so forth. The Spring container validates the configuration of each bean as the container is created. However, the bean properties themselves are not set until the bean is actually created. Beans that are singleton-scoped and set to be pre-instantiated (the default) are created when the container is created. Scopes are defined in Bean Scopes. Otherwise, the bean is created only when it is requested. Creation of a bean potentially causes a graph of beans to be created, as the bean’s dependencies and its dependencies' dependencies (and so on) are created and assigned. Note that resolution mismatches among those dependencies may show up late — that is, on first creation of the affected bean. Circular dependencies If you use predominantly constructor injection, it is possible to create an unresolvable circular dependency scenario. For example: Class A requires an instance of class B through constructor injection, and class B requires an instance of class A through constructor injection. If you configure beans for classes A and B to be injected into each other, the Spring IoC container detects this circular reference at runtime, and throws a BeanCurrentlyInCreationException. One possible solution is to edit the source code of some classes to be configured by setters rather than constructors. Alternatively, avoid constructor injection and use setter injection only. In other words, although it is not recommended, you can configure circular dependencies with setter injection. Unlike the typical case (with no circular dependencies), a circular dependency between bean A and bean B forces one of the beans to be injected into the other prior to being fully initialized itself (a classic chicken-and-egg scenario). You can generally trust Spring to do the right thing. It detects configuration problems, such as references to non-existent beans and circular dependencies, at container load-time. Spring sets properties and resolves dependencies as late as possible, when the bean is actually created. This means that a Spring container that has loaded correctly can later generate an exception when you request an object if there is a problem creating that object or one of its dependencies — for example, the bean throws an exception as a result of a missing or invalid property. This potentially delayed visibility of some configuration issues is why ApplicationContext implementations by default pre-instantiate singleton beans. At the cost of some upfront time and memory to create these beans before they are actually needed, you discover configuration issues when the ApplicationContext is created, not later. You can still override this default behavior so that singleton beans initialize lazily, rather than being eagerly pre-instantiated. If no circular dependencies exist, when one or more collaborating beans are being injected into a dependent bean, each collaborating bean is totally configured prior to being injected into the dependent bean. This means that, if bean A has a dependency on bean B, the Spring IoC container completely configures bean B prior to invoking the setter method on bean A. In other words, the bean is instantiated (if it is not a pre-instantiated singleton), its dependencies are set, and the relevant lifecycle methods (such as a configured init method or the InitializingBean callback method) are invoked. Examples of Dependency Injection The following example uses XML-based configuration metadata for setter-based DI. A small part of a Spring XML configuration file specifies some bean definitions as follows:               The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   private AnotherBean beanOne;   private YetAnotherBean beanTwo;   private int i;   public void setBeanOne(AnotherBean beanOne) {   this.beanOne = beanOne;   }   public void setBeanTwo(YetAnotherBean beanTwo) {   this.beanTwo = beanTwo;   }   public void setIntegerProperty(int i) {   this.i = i;   } } Kotlin class ExampleBean {   lateinit var beanOne: AnotherBean   lateinit var beanTwo: YetAnotherBean   var i: Int = 0 } In the preceding example, setters are declared to match against the properties specified in the XML file. The following example uses constructor-based DI:               The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   private AnotherBean beanOne;   private YetAnotherBean beanTwo;   private int i;   public ExampleBean(   AnotherBean anotherBean, YetAnotherBean yetAnotherBean, int i) {   this.beanOne = anotherBean;   this.beanTwo = yetAnotherBean;   this.i = i;   } } Kotlin class ExampleBean(   private val beanOne: AnotherBean,   private val beanTwo: YetAnotherBean,   private val i: Int) The constructor arguments specified in the bean definition are used as arguments to the constructor of the ExampleBean. Now consider a variant of this example, where, instead of using a constructor, Spring is told to call a static factory method to return an instance of the object:       The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   // a private constructor   private ExampleBean(...) {   ...   }   // a static factory method; the arguments to this method can be   // considered the dependencies of the bean that is returned,   // regardless of how those arguments are actually used.   public static ExampleBean createInstance (   AnotherBean anotherBean, YetAnotherBean yetAnotherBean, int i) {   ExampleBean eb = new ExampleBean (...);   // some other operations...   return eb;   } } Kotlin class ExampleBean private constructor() {   companion object {   // a static factory method; the arguments to this method can be   // considered the dependencies of the bean that is returned,   // regardless of how those arguments are actually used.   @JvmStatic   fun createInstance(anotherBean: AnotherBean, yetAnotherBean: YetAnotherBean, i: Int): ExampleBean {   val eb = ExampleBean (...)   // some other operations...   return eb   }   } } Arguments to the static factory method are supplied by elements, exactly the same as if a constructor had actually been used. The type of the class being returned by the factory method does not have to be of the same type as the class that contains the static factory method (although, in this example, it is). An instance (non-static) factory method can be used in an essentially identical fashion (aside from the use of the factory-bean attribute instead of the class attribute), so we do not discuss those details here. Dependencies and Configuration in Detail As mentioned in the previous section, you can define bean properties and constructor arguments as references to other managed beans (collaborators) or as values defined inline. Spring’s XML-based configuration metadata supports sub-element types within its and elements for this purpose. Straight Values (Primitives, Strings, and so on) The value attribute of the element specifies a property or constructor argument as a human-readable string representation. Spring’s conversion service is used to convert these values from a String to the actual type of the property or argument. The following example shows various values being set:           The following example uses the p-namespace for even more succinct XML configuration:   The preceding XML is more succinct. However, typos are discovered at runtime rather than design time, unless you use an IDE (such as IntelliJ IDEA or the Spring Tools for Eclipse) that supports automatic property completion when you create bean definitions. Such IDE assistance is highly recommended. You can also configure a java.util.Properties instance, as follows:         jdbc.driver.className=com.mysql.jdbc.Driver   jdbc.url=jdbc:mysql://localhost:3306/mydb     The Spring container converts the text inside the element into a java.util.Properties instance by using the JavaBeans PropertyEditor mechanism. This is a nice shortcut, and is one of a few places where the Spring team do favor the use of the nested element over the value attribute style. The idref element The idref element is simply an error-proof way to pass the id (a string value - not a reference) of another bean in the container to a or element. The following example shows how to use it:       The preceding bean definition snippet is exactly equivalent (at runtime) to the following snippet:   The first form is preferable to the second, because using the idref tag lets the container validate at deployment time that the referenced, named bean actually exists. In the second variation, no validation is performed on the value that is passed to the targetName property of the client bean. Typos are only discovered (with most likely fatal results) when the client bean is actually instantiated. If the client bean is a prototype bean, this typo and the resulting exception may only be discovered long after the container is deployed. The local attribute on the idref element is no longer supported in the 4.0 beans XSD, since it does not provide value over a regular bean reference any more.  Change your existing idref local references to idref bean when upgrading to the 4.0 schema. A common place (at least in versions earlier than Spring 2.0) where the element brings value is in the configuration of AOP interceptors in a ProxyFactoryBean bean definition. Using elements when you specify the interceptor names prevents you from misspelling an interceptor ID. References to Other Beans (Collaborators) The ref element is the final element inside a or definition element. Here, you set the value of the specified property of a bean to be a reference to another bean (a collaborator) managed by the container. The referenced bean is a dependency of the bean whose property is to be set, and it is initialized on demand as needed before the property is set. (If the collaborator is a singleton bean, it may already be initialized by the container.) All references are ultimately a reference to another object. Scoping and validation depend on whether you specify the ID or name of the other object through the bean or parent attribute. Specifying the target bean through the bean attribute of the tag is the most general form and allows creation of a reference to any bean in the same container or parent container, regardless of whether it is in the same XML file. The value of the bean attribute may be the same as the id attribute of the target bean or be the same as one of the values in the name attribute of the target bean. The following example shows how to use a ref element: Specifying the target bean through the parent attribute creates a reference to a bean that is in a parent container of the current container. The value of the parent attribute may be the same as either the id attribute of the target bean or one of the values in the name attribute of the target bean. The target bean must be in a parent container of the current one. You should use this bean reference variant mainly when you have a hierarchy of containers and you want to wrap an existing bean in a parent container with a proxy that has the same name as the parent bean. The following pair of listings shows how to use the parent attribute:     class="org.springframework.aop.framework.ProxyFactoryBean">         The local attribute on the ref element is no longer supported in the 4.0 beans XSD,  since it does not provide value over a regular bean reference any more. Change your existing ref local references to ref bean when upgrading to the 4.0 schema. Inner Beans A element inside the or elements defines an inner bean, as the following example shows:               An inner bean definition does not require a defined ID or name. If specified, the container does not use such a value as an identifier. The container also ignores the scope flag on creation, because inner beans are always anonymous and are always created with the outer bean. It is not possible to access inner beans independently or to inject them into collaborating beans other than into the enclosing bean. As a corner case, it is possible to receive destruction callbacks from a custom scope — for example, for a request-scoped inner bean contained within a singleton bean. The creation of the inner bean instance is tied to its containing bean, but destruction callbacks let it participate in the request scope’s lifecycle. This is not a common scenario. Inner beans typically simply share their containing bean’s scope. Collections The , , , and elements set the properties and arguments of the Java Collection types List, Set, Map, and Properties, respectively. The following example shows how to use them:         administrator@example.org   support@example.org   development@example.org             a list element followed by a reference                             just some string       The value of a map key or value, or a set value, can also be any of the following elements: bean | ref | idref | list | set | map | props | value | null Collection Merging The Spring container also supports merging collections. An application developer can define a parent , , or element and have child , , or elements inherit and override values from the parent collection. That is, the child collection’s values are the result of merging the elements of the parent and child collections, with the child’s collection elements overriding values specified in the parent collection. This section on merging discusses the parent-child bean mechanism. Readers unfamiliar with parent and child bean definitions may wish to read the relevant section before continuing. The following example demonstrates collection merging:         administrator@example.com   support@example.com                 sales@example.com   support@example.co.uk       Notice the use of the merge=true attribute on the element of the adminEmails property of the child bean definition. When the child bean is resolved and instantiated by the container, the resulting instance has an adminEmails Properties collection that contains the result of merging the child’s adminEmails collection with the parent’s adminEmails collection. The following listing shows the result: administrator=administrator@example.com sales=sales@example.com support=support@example.co.uk The child Properties collection’s value set inherits all property elements from the parent , and the child’s value for the support value overrides the value in the parent collection. This merging behavior applies similarly to the , , and collection types. In the specific case of the element, the semantics associated with the List collection type (that is, the notion of an ordered collection of values) is maintained. The parent’s values precede all of the child list’s values. In the case of the Map, Set, and Properties collection types, no ordering exists. Hence, no ordering semantics are in effect for the collection types that underlie the associated Map, Set, and Properties implementation types that the container uses internally. Limitations of Collection Merging You cannot merge different collection types (such as a Map and a List). If you do attempt to do so, an appropriate Exception is thrown. The merge attribute must be specified on the lower, inherited, child definition. Specifying the merge attribute on a parent collection definition is redundant and does not result in the desired merging. Strongly-typed collection Thanks to Java’s support for generic types, you can use strongly typed collections. That is, it is possible to declare a Collection type such that it can only contain (for example) String elements. If you use Spring to dependency-inject a strongly-typed Collection into a bean, you can take advantage of Spring’s type-conversion support such that the elements of your strongly-typed Collection instances are converted to the appropriate type prior to being added to the Collection. The following Java class and bean definition show how to do so: Java public class SomeClass {   private Map accounts;   public void setAccounts(Map accounts) {   this.accounts = accounts;   } } Kotlin class SomeClass {   lateinit var accounts: Map }                   When the accounts property of the something bean is prepared for injection, the generics information about the element type of the strongly-typed Map is available by reflection. Thus, Spring’s type conversion infrastructure recognizes the various value elements as being of type Float, and the string values (9.99, 2.75, and 3.99) are converted into an actual Float type. Null and Empty String Values Spring treats empty arguments for properties and the like as empty Strings. The following XML- based configuration metadata snippet sets the email property to the empty String value ("").   The preceding example is equivalent to the following Java code: Java exampleBean.setEmail(""); Kotlin exampleBean.email = "" The element handles null values. The following listing shows an example:       The preceding configuration is equivalent to the following Java code: Java exampleBean.setEmail(null); Kotlin exampleBean.email = null XML Shortcut with the p-namespace The p-namespace lets you use the bean element’s attributes (instead of nested elements) to describe your property values collaborating beans, or both. Spring supports extensible configuration formats with namespaces, which are based on an XML Schema definition. The beans configuration format discussed in this chapter is defined in an XML Schema document. However, the p-namespace is not defined in an XSD file and exists only in the core of Spring. The following example shows two XML snippets (the first uses standard XML format and the second uses the p-namespace) that resolve to the same result:         The example shows an attribute in the p-namespace called email in the bean definition. This tells Spring to include a property declaration. As previously mentioned, the p-namespace does not have a schema definition, so you can set the name of the attribute to the property name. This next example includes two more bean definitions that both have a reference to another bean:                 This example includes not only a property value using the p-namespace but also uses a special format to declare property references. Whereas the first bean definition uses to create a reference from bean john to bean jane, the second bean definition uses p:spouse-ref="jane" as an attribute to do the exact same thing. In this case, spouse is the property name, whereas the -ref part indicates that this is not a straight value but rather a reference to another bean. The p-namespace is not as flexible as the standard XML format. For example, the format for declaring property references clashes with properties that end in Ref,  whereas the standard XML format does not. We recommend that you choose your approach carefully and communicate this to your team members to avoid producing XML documents that use all three approaches at the same time. XML Shortcut with the c-namespace Similar to the XML Shortcut with the p-namespace, the c-namespace, introduced in Spring 3.1, allows inlined attributes for configuring the constructor arguments rather then nested constructor- arg elements. The following example uses the c: namespace to do the same thing as the from Constructor-based Dependency Injection:                     The c: namespace uses the same conventions as the p: one (a trailing -ref for bean references) for setting the constructor arguments by their names. Similarly, it needs to be declared in the XML file even though it is not defined in an XSD schema (it exists inside the Spring core). For the rare cases where the constructor argument names are not available (usually if the bytecode was compiled without debugging information), you can use fallback to the argument indexes, as follows: Due to the XML grammar, the index notation requires the presence of the leading _, as XML attribute names cannot start with a number (even though some IDEs  allow it). A corresponding index notation is also available for elements but not commonly used since the plain order of declaration is usually sufficient there. In practice, the constructor resolution mechanism is quite efficient in matching arguments, so unless you really need to, we recommend using the name notation throughout your configuration. Compound Property Names You can use compound or nested property names when you set bean properties, as long as all components of the path except the final property name are not null. Consider the following bean definition:   The something bean has a fred property, which has a bob property, which has a sammy property, and that final sammy property is being set to a value of 123. In order for this to work, the fred property of something and the bob property of fred must not be null after the bean is constructed. Otherwise, a NullPointerException is thrown. Using depends-on If a bean is a dependency of another bean, that usually means that one bean is set as a property of another. Typically you accomplish this with the element in XML-based configuration metadata. However, sometimes dependencies between beans are less direct. An example is when a static initializer in a class needs to be triggered, such as for database driver registration. The depends-on attribute can explicitly force one or more beans to be initialized before the bean using this element is initialized. The following example uses the depends-on attribute to express a dependency on a single bean: To express a dependency on multiple beans, supply a list of bean names as the value of the depends- on attribute (commas, whitespace, and semicolons are valid delimiters):   The depends-on attribute can specify both an initialization-time dependency and, in the case of singleton beans only, a corresponding destruction-time dependency.  Dependent beans that define a depends-on relationship with a given bean are destroyed first, prior to the given bean itself being destroyed. Thus, depends-on can also control shutdown order. Lazy-initialized Beans By default, ApplicationContext implementations eagerly create and configure all singleton beans as part of the initialization process. Generally, this pre-instantiation is desirable, because errors in the configuration or surrounding environment are discovered immediately, as opposed to hours or even days later. When this behavior is not desirable, you can prevent pre-instantiation of a singleton bean by marking the bean definition as being lazy-initialized. A lazy-initialized bean tells the IoC container to create a bean instance when it is first requested, rather than at startup. In XML, this behavior is controlled by the lazy-init attribute on the element, as the following example shows: When the preceding configuration is consumed by an ApplicationContext, the lazy bean is not eagerly pre-instantiated when the ApplicationContext starts, whereas the not.lazy bean is eagerly pre-instantiated. However, when a lazy-initialized bean is a dependency of a singleton bean that is not lazy- initialized, the ApplicationContext creates the lazy-initialized bean at startup, because it must satisfy the singleton’s dependencies. The lazy-initialized bean is injected into a singleton bean elsewhere that is not lazy-initialized. You can also control lazy-initialization at the container level by using the default-lazy-init attribute on the element, as the following example shows:   Autowiring Collaborators The Spring container can autowire relationships between collaborating beans. You can let Spring resolve collaborators (other beans) automatically for your bean by inspecting the contents of the ApplicationContext. Autowiring has the following advantages: • Autowiring can significantly reduce the need to specify properties or constructor arguments. (Other mechanisms such as a bean template discussed elsewhere in this chapter are also valuable in this regard.) • Autowiring can update a configuration as your objects evolve. For example, if you need to add a dependency to a class, that dependency can be satisfied automatically without you needing to modify the configuration. Thus autowiring can be especially useful during development, without negating the option of switching to explicit wiring when the code base becomes more stable. When using XML-based configuration metadata (see Dependency Injection), you can specify the autowire mode for a bean definition with the autowire attribute of the element. The autowiring functionality has four modes. You specify autowiring per bean and can thus choose which ones to autowire. The following table describes the four autowiring modes: Table 2. Autowiring modes Mode Explanation no (Default) No autowiring. Bean references must be defined by ref elements. Changing the default setting is not recommended for larger deployments, because specifying collaborators explicitly gives greater control and clarity. To some extent, it documents the structure of a system. byName Autowiring by property name. Spring looks for a bean with the same name as the property that needs to be autowired. For example, if a bean definition is set to autowire by name and it contains a master property (that is, it has a setMaster(..) method), Spring looks for a bean definition named master and uses it to set the property. byType Lets a property be autowired if exactly one bean of the property type exists in the container. If more than one exists, a fatal exception is thrown, which indicates that you may not use byType autowiring for that bean. If there are no matching beans, nothing happens (the property is not set). constructor Analogous to byType but applies to constructor arguments. If there is not exactly one bean of the constructor argument type in the container, a fatal error is raised. With byType or constructor autowiring mode, you can wire arrays and typed collections. In such cases, all autowire candidates within the container that match the expected type are provided to satisfy the dependency. You can autowire strongly-typed Map instances if the expected key type is String. An autowired Map instance’s values consist of all bean instances that match the expected type, and the Map instance’s keys contain the corresponding bean names. Limitations and Disadvantages of Autowiring Autowiring works best when it is used consistently across a project. If autowiring is not used in general, it might be confusing to developers to use it to wire only one or two bean definitions. Consider the limitations and disadvantages of autowiring: • Explicit dependencies in property and constructor-arg settings always override autowiring. You cannot autowire simple properties such as primitives, Strings, and Classes (and arrays of such simple properties). This limitation is by-design. • Autowiring is less exact than explicit wiring. Although, as noted in the earlier table, Spring is careful to avoid guessing in case of ambiguity that might have unexpected results. The relationships between your Spring-managed objects are no longer documented explicitly. • Wiring information may not be available to tools that may generate documentation from a Spring container. • Multiple bean definitions within the container may match the type specified by the setter method or constructor argument to be autowired. For arrays, collections, or Map instances, this is not necessarily a problem. However, for dependencies that expect a single value, this ambiguity is not arbitrarily resolved. If no unique bean definition is available, an exception is thrown. In the latter scenario, you have several options: • Abandon autowiring in favor of explicit wiring. • Avoid autowiring for a bean definition by setting its autowire-candidate attributes to false, as described in the next section. • Designate a single bean definition as the primary candidate by setting the primary attribute of its element to true. • Implement the more fine-grained control available with annotation-based configuration, as described in Annotation-based Container Configuration. Excluding a Bean from Autowiring On a per-bean basis, you can exclude a bean from autowiring. In Spring’s XML format, set the autowire-candidate attribute of the element to false. The container makes that specific bean definition unavailable to the autowiring infrastructure (including annotation style configurations such as @Autowired). The autowire-candidate attribute is designed to only affect type-based autowiring. It does not affect explicit references by name, which get resolved even if the  specified bean is not marked as an autowire candidate. As a consequence, autowiring by name nevertheless injects a bean if the name matches. You can also limit autowire candidates based on pattern-matching against bean names. The top- level element accepts one or more patterns within its default-autowire-candidates attribute. For example, to limit autowire candidate status to any bean whose name ends with Repository, provide a value of *Repository. To provide multiple patterns, define them in a comma- separated list. An explicit value of true or false for a bean definition’s autowire-candidate attribute always takes precedence. For such beans, the pattern matching rules do not apply. These techniques are useful for beans that you never want to be injected into other beans by autowiring. It does not mean that an excluded bean cannot itself be configured by using autowiring. Rather, the bean itself is not a candidate for autowiring other beans. Method Injection In most application scenarios, most beans in the container are singletons. When a singleton bean needs to collaborate with another singleton bean or a non-singleton bean needs to collaborate with another non-singleton bean, you typically handle the dependency by defining one bean as a property of the other. A problem arises when the bean lifecycles are different. Suppose singleton bean A needs to use non-singleton (prototype) bean B, perhaps on each method invocation on A. The container creates the singleton bean A only once, and thus only gets one opportunity to set the properties. The container cannot provide bean A with a new instance of bean B every time one is needed. A solution is to forego some inversion of control. You can make bean A aware of the container by implementing the ApplicationContextAware interface, and by making a getBean("B") call to the container ask for (a typically new) bean B instance every time bean A needs it. The following example shows this approach: Java // a class that uses a stateful Command-style class to perform some processing package fiona.apple; // Spring-API imports import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; public class CommandManager implements ApplicationContextAware {   private ApplicationContext applicationContext;   public Object process(Map commandState) {   // grab a new instance of the appropriate Command   Command command = createCommand();   // set the state on the (hopefully brand new) Command instance   command.setState(commandState);   return command.execute();   }   protected Command createCommand() {   // notice the Spring API dependency!   return this.applicationContext.getBean("command", Command.class);   }   public void setApplicationContext(   ApplicationContext applicationContext) throws BeansException {   this.applicationContext = applicationContext;   } } Kotlin // a class that uses a stateful Command-style class to perform some processing package fiona.apple // Spring-API imports import org.springframework.context.ApplicationContext import org.springframework.context.ApplicationContextAware class CommandManager : ApplicationContextAware {   private lateinit var applicationContext: ApplicationContext   fun process(commandState: Map<*, *>): Any {   // grab a new instance of the appropriate Command   val command = createCommand()   // set the state on the (hopefully brand new) Command instance   command.state = commandState   return command.execute()   }   // notice the Spring API dependency!   protected fun createCommand() =   applicationContext.getBean("command", Command::class.java)   override fun setApplicationContext(applicationContext: ApplicationContext) {   this.applicationContext = applicationContext   } } The preceding is not desirable, because the business code is aware of and coupled to the Spring Framework. Method Injection, a somewhat advanced feature of the Spring IoC container, lets you handle this use case cleanly. You can read more about the motivation for Method Injection in this blog entry. Lookup Method Injection Lookup method injection is the ability of the container to override methods on container-managed beans and return the lookup result for another named bean in the container. The lookup typically involves a prototype bean, as in the scenario described in the preceding section. The Spring Framework implements this method injection by using bytecode generation from the CGLIB library to dynamically generate a subclass that overrides the method. • For this dynamic subclassing to work, the class that the Spring bean container subclasses cannot be final, and the method to be overridden cannot be final, either. • Unit-testing a class that has an abstract method requires you to subclass the class yourself and to supply a stub implementation of the abstract method.  • Concrete methods are also necessary for component scanning, which requires concrete classes to pick up. • A further key limitation is that lookup methods do not work with factory methods and in particular not with @Bean methods in configuration classes, since, in that case, the container is not in charge of creating the instance and therefore cannot create a runtime-generated subclass on the fly. In the case of the CommandManager class in the previous code snippet, the Spring container dynamically overrides the implementation of the createCommand() method. The CommandManager class does not have any Spring dependencies, as the reworked example shows: Java package fiona.apple; // no more Spring imports! public abstract class CommandManager {   public Object process(Object commandState) {   // grab a new instance of the appropriate Command interface   Command command = createCommand();   // set the state on the (hopefully brand new) Command instance   command.setState(commandState);   return command.execute();   }   // okay... but where is the implementation of this method?   protected abstract Command createCommand(); } Kotlin package fiona.apple // no more Spring imports! abstract class CommandManager {   fun process(commandState: Any): Any {   // grab a new instance of the appropriate Command interface   val command = createCommand()   // set the state on the (hopefully brand new) Command instance   command.state = commandState   return command.execute()   }   // okay... but where is the implementation of this method?   protected abstract fun createCommand(): Command } In the client class that contains the method to be injected (the CommandManager in this case), the method to be injected requires a signature of the following form: [abstract] theMethodName(no-arguments); If the method is abstract, the dynamically-generated subclass implements the method. Otherwise, the dynamically-generated subclass overrides the concrete method defined in the original class. Consider the following example:     The bean identified as commandManager calls its own createCommand() method whenever it needs a new instance of the myCommand bean. You must be careful to deploy the myCommand bean as a prototype if that is actually what is needed. If it is a singleton, the same instance of the myCommand bean is returned each time. Alternatively, within the annotation-based component model, you can declare a lookup method through the @Lookup annotation, as the following example shows: Java public abstract class CommandManager {   public Object process(Object commandState) {   Command command = createCommand();   command.setState(commandState);   return command.execute();   }   @Lookup("myCommand")   protected abstract Command createCommand(); } Kotlin abstract class CommandManager {   fun process(commandState: Any): Any {   val command = createCommand()   command.state = commandState   return command.execute()   }   @Lookup("myCommand")   protected abstract fun createCommand(): Command } Or, more idiomatically, you can rely on the target bean getting resolved against the declared return type of the lookup method: Java public abstract class CommandManager {   public Object process(Object commandState) {   Command command = createCommand();   command.setState(commandState);   return command.execute();   }   @Lookup   protected abstract Command createCommand(); } Kotlin abstract class CommandManager {   fun process(commandState: Any): Any {   val command = createCommand()   command.state = commandState   return command.execute()   }   @Lookup   protected abstract fun createCommand(): Command } Note that you should typically declare such annotated lookup methods with a concrete stub implementation, in order for them to be compatible with Spring’s component scanning rules where abstract classes get ignored by default. This limitation does not apply to explicitly registered or explicitly imported bean classes. Another way of accessing differently scoped target beans is an ObjectFactory/ Provider injection point. See Scoped Beans as Dependencies.  You may also find the ServiceLocatorFactoryBean (in the org.springframework.beans.factory.config package) to be useful. Arbitrary Method Replacement A less useful form of method injection than lookup method injection is the ability to replace arbitrary methods in a managed bean with another method implementation. You can safely skip the rest of this section until you actually need this functionality. With XML-based configuration metadata, you can use the replaced-method element to replace an existing method implementation with another, for a deployed bean. Consider the following class, which has a method called computeValue that we want to override: Java public class MyValueCalculator {   public String computeValue(String input) {   // some real code...   }   // some other methods... } Kotlin class MyValueCalculator {   fun computeValue(input: String): String {   // some real code...   }   // some other methods... } A class that implements the org.springframework.beans.factory.support.MethodReplacer interface provides the new method definition, as the following example shows: Java /**  * meant to be used to override the existing computeValue(String)  * implementation in MyValueCalculator  */ public class ReplacementComputeValue implements MethodReplacer {   public Object reimplement(Object o, Method m, Object[] args) throws Throwable {   // get the input value, work with it, and return a computed result   String input = (String) args[0];   ...   return ...;   } } Kotlin /**  * meant to be used to override the existing computeValue(String)  * implementation in MyValueCalculator  */ class ReplacementComputeValue : MethodReplacer {   override fun reimplement(obj: Any, method: Method, args: Array): Any {   // get the input value, work with it, and return a computed result   val input = args[0] as String;   ...   return ...;   } } The bean definition to deploy the original class and specify the method override would resemble the following example:       String   You can use one or more elements within the element to indicate the method signature of the method being overridden. The signature for the arguments is necessary only if the method is overloaded and multiple variants exist within the class. For convenience, the type string for an argument may be a substring of the fully qualified type name. For example, the following all match java.lang.String: java.lang.String String Str Because the number of arguments is often enough to distinguish between each possible choice, this shortcut can save a lot of typing, by letting you type only the shortest string that matches an argument type. 2.1.5. Bean Scopes When you create a bean definition, you create a recipe for creating actual instances of the class defined by that bean definition. The idea that a bean definition is a recipe is important, because it means that, as with a class, you can create many object instances from a single recipe. You can control not only the various dependencies and configuration values that are to be plugged into an object that is created from a particular bean definition but also control the scope of the objects created from a particular bean definition. This approach is powerful and flexible, because you can choose the scope of the objects you create through configuration instead of having to bake in the scope of an object at the Java class level. Beans can be defined to be deployed in one of a number of scopes. The Spring Framework supports six scopes, four of which are available only if you use a web-aware ApplicationContext. You can also create a custom scope. The following table describes the supported scopes: Table 3. Bean scopes Scope Description singleton (Default) Scopes a single bean definition to a single object instance for each Spring IoC container. prototype Scopes a single bean definition to any number of object instances. Scope Description request Scopes a single bean definition to the lifecycle of a single HTTP request. That is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext. session Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext. application Scopes a single bean definition to the lifecycle of a ServletContext. Only valid in the context of a web-aware Spring ApplicationContext. websocket Scopes a single bean definition to the lifecycle of a WebSocket. Only valid in the context of a web-aware Spring ApplicationContext. As of Spring 3.0, a thread scope is available but is not registered by default. For  more information, see the documentation for SimpleThreadScope. For instructions on how to register this or any other custom scope, see Using a Custom Scope. The Singleton Scope Only one shared instance of a singleton bean is managed, and all requests for beans with an ID or IDs that match that bean definition result in that one specific bean instance being returned by the Spring container. To put it another way, when you define a bean definition and it is scoped as a singleton, the Spring IoC container creates exactly one instance of the object defined by that bean definition. This single instance is stored in a cache of such singleton beans, and all subsequent requests and references for that named bean return the cached object. The following image shows how the singleton scope works: Spring’s concept of a singleton bean differs from the singleton pattern as defined in the Gang of Four (GoF) patterns book. The GoF singleton hard-codes the scope of an object such that one and only one instance of a particular class is created per ClassLoader. The scope of the Spring singleton is best described as being per-container and per-bean. This means that, if you define one bean for a particular class in a single Spring container, the Spring container creates one and only one instance of the class defined by that bean definition. The singleton scope is the default scope in Spring. To define a bean as a singleton in XML, you can define a bean as shown in the following example: The Prototype Scope The non-singleton prototype scope of bean deployment results in the creation of a new bean instance every time a request for that specific bean is made. That is, the bean is injected into another bean or you request it through a getBean() method call on the container. As a rule, you should use the prototype scope for all stateful beans and the singleton scope for stateless beans. The following diagram illustrates the Spring prototype scope: (A data access object (DAO) is not typically configured as a prototype, because a typical DAO does not hold any conversational state. It was easier for us to reuse the core of the singleton diagram.) The following example defines a bean as a prototype in XML: In contrast to the other scopes, Spring does not manage the complete lifecycle of a prototype bean. The container instantiates, configures, and otherwise assembles a prototype object and hands it to the client, with no further record of that prototype instance. Thus, although initialization lifecycle callback methods are called on all objects regardless of scope, in the case of prototypes, configured destruction lifecycle callbacks are not called. The client code must clean up prototype-scoped objects and release expensive resources that the prototype beans hold. To get the Spring container to release resources held by prototype-scoped beans, try using a custom bean post-processor, which holds a reference to beans that need to be cleaned up. In some respects, the Spring container’s role in regard to a prototype-scoped bean is a replacement for the Java new operator. All lifecycle management past that point must be handled by the client. (For details on the lifecycle of a bean in the Spring container, see Lifecycle Callbacks.) Singleton Beans with Prototype-bean Dependencies When you use singleton-scoped beans with dependencies on prototype beans, be aware that dependencies are resolved at instantiation time. Thus, if you dependency-inject a prototype-scoped bean into a singleton-scoped bean, a new prototype bean is instantiated and then dependency- injected into the singleton bean. The prototype instance is the sole instance that is ever supplied to the singleton-scoped bean. However, suppose you want the singleton-scoped bean to acquire a new instance of the prototype- scoped bean repeatedly at runtime. You cannot dependency-inject a prototype-scoped bean into your singleton bean, because that injection occurs only once, when the Spring container instantiates the singleton bean and resolves and injects its dependencies. If you need a new instance of a prototype bean at runtime more than once, see Method Injection. Request, Session, Application, and WebSocket Scopes The request, session, application, and websocket scopes are available only if you use a web-aware Spring ApplicationContext implementation (such as XmlWebApplicationContext). If you use these scopes with regular Spring IoC containers, such as the ClassPathXmlApplicationContext, an IllegalStateException that complains about an unknown bean scope is thrown. Initial Web Configuration To support the scoping of beans at the request, session, application, and websocket levels (web- scoped beans), some minor initial configuration is required before you define your beans. (This initial setup is not required for the standard scopes: singleton and prototype.) How you accomplish this initial setup depends on your particular Servlet environment. If you access scoped beans within Spring Web MVC, in effect, within a request that is processed by the Spring DispatcherServlet, no special setup is necessary. DispatcherServlet already exposes all relevant state. If you use a Servlet web container, with requests processed outside of Spring’s DispatcherServlet (for example, when using JSF or Struts), you need to register the org.springframework.web.context.request.RequestContextListener ServletRequestListener. This can be done programmatically by using the WebApplicationInitializer interface. Alternatively, add the following declaration to your web application’s web.xml file:   ...       org.springframework.web.context.request.RequestContextListener       ... Alternatively, if there are issues with your listener setup, consider using Spring’s RequestContextFilter. The filter mapping depends on the surrounding web application configuration, so you have to change it as appropriate. The following listing shows the filter part of a web application:   ...     requestContextFilter   org.springframework.web.filter.RequestContextFilter       requestContextFilter   /*     ... DispatcherServlet, RequestContextListener, and RequestContextFilter all do exactly the same thing, namely bind the HTTP request object to the Thread that is servicing that request. This makes beans that are request- and session-scoped available further down the call chain. Request scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the LoginAction bean by using the loginAction bean definition for each and every HTTP request. That is, the loginAction bean is scoped at the HTTP request level. You can change the internal state of the instance that is created as much as you want, because other instances created from the same loginAction bean definition do not see these changes in state. They are particular to an individual request. When the request completes processing, the bean that is scoped to the request is discarded. When using annotation-driven components or Java configuration, the @RequestScope annotation can be used to assign a component to the request scope. The following example shows how to do so: Java @RequestScope @Component public class LoginAction {   // ... } Kotlin @RequestScope @Component class LoginAction {   // ... } Session Scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the UserPreferences bean by using the userPreferences bean definition for the lifetime of a single HTTP Session. In other words, the userPreferences bean is effectively scoped at the HTTP Session level. As with request-scoped beans, you can change the internal state of the instance that is created as much as you want, knowing that other HTTP Session instances that are also using instances created from the same userPreferences bean definition do not see these changes in state, because they are particular to an individual HTTP Session. When the HTTP Session is eventually discarded, the bean that is scoped to that particular HTTP Session is also discarded. When using annotation-driven components or Java configuration, you can use the @SessionScope annotation to assign a component to the session scope. Java @SessionScope @Component public class UserPreferences {   // ... } Kotlin @SessionScope @Component class UserPreferences {   // ... } Application Scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the AppPreferences bean by using the appPreferences bean definition once for the entire web application. That is, the appPreferences bean is scoped at the ServletContext level and stored as a regular ServletContext attribute. This is somewhat similar to a Spring singleton bean but differs in two important ways: It is a singleton per ServletContext, not per Spring ApplicationContext (for which there may be several in any given web application), and it is actually exposed and therefore visible as a ServletContext attribute. When using annotation-driven components or Java configuration, you can use the @ApplicationScope annotation to assign a component to the application scope. The following example shows how to do so: Java @ApplicationScope @Component public class AppPreferences {   // ... } Kotlin @ApplicationScope @Component class AppPreferences {   // ... } WebSocket Scope WebSocket scope is associated with the lifecycle of a WebSocket session and applies to STOMP over WebSocket applications, see WebSocket scope for more details. Scoped Beans as Dependencies The Spring IoC container manages not only the instantiation of your objects (beans), but also the wiring up of collaborators (or dependencies). If you want to inject (for example) an HTTP request- scoped bean into another bean of a longer-lived scope, you may choose to inject an AOP proxy in place of the scoped bean. That is, you need to inject a proxy object that exposes the same public interface as the scoped object but that can also retrieve the real target object from the relevant scope (such as an HTTP request) and delegate method calls onto the real object. You may also use between beans that are scoped as singleton, with the reference then going through an intermediate proxy that is serializable and therefore able to re-obtain the target singleton bean on deserialization. When declaring against a bean of scope prototype, every method call on the shared proxy leads to the creation of a new target instance to which the call is then being forwarded. Also, scoped proxies are not the only way to access beans from shorter scopes in a lifecycle-safe fashion. You may also declare your injection point (that is, the  constructor or setter argument or autowired field) as ObjectFactory, allowing for a getObject() call to retrieve the current instance on demand every time it is needed — without holding on to the instance or storing it separately. As an extended variant, you may declare ObjectProvider which delivers several additional access variants, including getIfAvailable and getIfUnique. The JSR-330 variant of this is called Provider and is used with a Provider declaration and a corresponding get() call for every retrieval attempt. See here for more details on JSR-330 overall. The configuration in the following example is only one line, but it is important to understand the “why” as well as the “how” behind it:         ①             ① The line that defines the proxy. To create such a proxy, you insert a child element into a scoped bean definition (see Choosing the Type of Proxy to Create and XML Schema-based configuration). Why do definitions of beans scoped at the request, session and custom-scope levels require the element? Consider the following singleton bean definition and contrast it with what you need to define for the aforementioned scopes (note that the following userPreferences bean definition as it stands is incomplete):   In the preceding example, the singleton bean (userManager) is injected with a reference to the HTTP Session-scoped bean (userPreferences). The salient point here is that the userManager bean is a singleton: it is instantiated exactly once per container, and its dependencies (in this case only one, the userPreferences bean) are also injected only once. This means that the userManager bean operates only on the exact same userPreferences object (that is, the one with which it was originally injected). This is not the behavior you want when injecting a shorter-lived scoped bean into a longer-lived scoped bean (for example, injecting an HTTP Session-scoped collaborating bean as a dependency into singleton bean). Rather, you need a single userManager object, and, for the lifetime of an HTTP Session, you need a userPreferences object that is specific to the HTTP Session. Thus, the container creates an object that exposes the exact same public interface as the UserPreferences class (ideally an object that is a UserPreferences instance), which can fetch the real UserPreferences object from the scoping mechanism (HTTP request, Session, and so forth). The container injects this proxy object into the userManager bean, which is unaware that this UserPreferences reference is a proxy. In this example, when a UserManager instance invokes a method on the dependency-injected UserPreferences object, it is actually invoking a method on the proxy. The proxy then fetches the real UserPreferences object from (in this case) the HTTP Session and delegates the method invocation onto the retrieved real UserPreferences object. Thus, you need the following (correct and complete) configuration when injecting request- and session-scoped beans into collaborating objects, as the following example shows:     Choosing the Type of Proxy to Create By default, when the Spring container creates a proxy for a bean that is marked up with the element, a CGLIB-based class proxy is created. CGLIB proxies intercept only public method calls! Do not call non-public methods  on such a proxy. They are not delegated to the actual scoped target object. Alternatively, you can configure the Spring container to create standard JDK interface-based proxies for such scoped beans, by specifying false for the value of the proxy-target-class attribute of the element. Using JDK interface-based proxies means that you do not need additional libraries in your application classpath to affect such proxying. However, it also means that the class of the scoped bean must implement at least one interface and that all collaborators into which the scoped bean is injected must reference the bean through one of its interfaces. The following example shows a proxy based on an interface:     For more detailed information about choosing class-based or interface-based proxying, see Proxying Mechanisms. Custom Scopes The bean scoping mechanism is extensible. You can define your own scopes or even redefine existing scopes, although the latter is considered bad practice and you cannot override the built-in singleton and prototype scopes. Creating a Custom Scope To integrate your custom scopes into the Spring container, you need to implement the org.springframework.beans.factory.config.Scope interface, which is described in this section. For an idea of how to implement your own scopes, see the Scope implementations that are supplied with the Spring Framework itself and the Scope javadoc, which explains the methods you need to implement in more detail. The Scope interface has four methods to get objects from the scope, remove them from the scope, and let them be destroyed. The session scope implementation, for example, returns the session-scoped bean (if it does not exist, the method returns a new instance of the bean, after having bound it to the session for future reference). The following method returns the object from the underlying scope: Java Object get(String name, ObjectFactory objectFactory) Kotlin fun get(name: String, objectFactory: ObjectFactory<*>): Any The session scope implementation, for example, removes the session-scoped bean from the underlying session. The object should be returned, but you can return null if the object with the specified name is not found. The following method removes the object from the underlying scope: Java Object remove(String name) Kotlin fun remove(name: String): Any The following method registers a callback that the scope should invoke when it is destroyed or when the specified object in the scope is destroyed: Java void registerDestructionCallback(String name, Runnable destructionCallback) Kotlin fun registerDestructionCallback(name: String, destructionCallback: Runnable) See the javadoc or a Spring scope implementation for more information on destruction callbacks. The following method obtains the conversation identifier for the underlying scope: Java String getConversationId() Kotlin fun getConversationId(): String This identifier is different for each scope. For a session scoped implementation, this identifier can be the session identifier. Using a Custom Scope After you write and test one or more custom Scope implementations, you need to make the Spring container aware of your new scopes. The following method is the central method to register a new Scope with the Spring container: Java void registerScope(String scopeName, Scope scope); Kotlin fun registerScope(scopeName: String, scope: Scope) This method is declared on the ConfigurableBeanFactory interface, which is available through the BeanFactory property on most of the concrete ApplicationContext implementations that ship with Spring. The first argument to the registerScope(..) method is the unique name associated with a scope. Examples of such names in the Spring container itself are singleton and prototype. The second argument to the registerScope(..) method is an actual instance of the custom Scope implementation that you wish to register and use. Suppose that you write your custom Scope implementation, and then register it as shown in the next example. The next example uses SimpleThreadScope, which is included with Spring but is not  registered by default. The instructions would be the same for your own custom Scope implementations. Java Scope threadScope = new SimpleThreadScope(); beanFactory.registerScope("thread", threadScope); Kotlin val threadScope = SimpleThreadScope() beanFactory.registerScope("thread", threadScope) You can then create bean definitions that adhere to the scoping rules of your custom Scope, as follows: With a custom Scope implementation, you are not limited to programmatic registration of the scope. You can also do the Scope registration declaratively, by using the CustomScopeConfigurer class, as the following example shows:                                 When you place within a declaration for a FactoryBean  implementation, it is the factory bean itself that is scoped, not the object returned from getObject(). 2.1.6. Customizing the Nature of a Bean The Spring Framework provides a number of interfaces you can use to customize the nature of a bean. This section groups them as follows: • Lifecycle Callbacks • ApplicationContextAware and BeanNameAware • Other Aware Interfaces Lifecycle Callbacks To interact with the container’s management of the bean lifecycle, you can implement the Spring InitializingBean and DisposableBean interfaces. The container calls afterPropertiesSet() for the former and destroy() for the latter to let the bean perform certain actions upon initialization and destruction of your beans. The JSR-250 @PostConstruct and @PreDestroy annotations are generally considered best practice for receiving lifecycle callbacks in a modern Spring application. Using these annotations means that your beans are not coupled to Spring-specific  interfaces. For details, see Using @PostConstruct and @PreDestroy. If you do not want to use the JSR-250 annotations but you still want to remove coupling, consider init-method and destroy-method bean definition metadata. Internally, the Spring Framework uses BeanPostProcessor implementations to process any callback interfaces it can find and call the appropriate methods. If you need custom features or other lifecycle behavior Spring does not by default offer, you can implement a BeanPostProcessor yourself. For more information, see Container Extension Points. In addition to the initialization and destruction callbacks, Spring-managed objects may also implement the Lifecycle interface so that those objects can participate in the startup and shutdown process, as driven by the container’s own lifecycle. The lifecycle callback interfaces are described in this section. Initialization Callbacks The org.springframework.beans.factory.InitializingBean interface lets a bean perform initialization work after the container has set all necessary properties on the bean. The InitializingBean interface specifies a single method: void afterPropertiesSet() throws Exception; We recommend that you do not use the InitializingBean interface, because it unnecessarily couples the code to Spring. Alternatively, we suggest using the @PostConstruct annotation or specifying a POJO initialization method. In the case of XML-based configuration metadata, you can use the init- method attribute to specify the name of the method that has a void no-argument signature. With Java configuration, you can use the initMethod attribute of @Bean. See Receiving Lifecycle Callbacks. Consider the following example: Java public class ExampleBean {   public void init() {   // do some initialization work   } } Kotlin class ExampleBean {   fun init() {   // do some initialization work   } } The preceding example has almost exactly the same effect as the following example (which consists of two listings): Java public class AnotherExampleBean implements InitializingBean {   @Override   public void afterPropertiesSet() {   // do some initialization work   } } Kotlin class AnotherExampleBean : InitializingBean {   override fun afterPropertiesSet() {   // do some initialization work   } } However, the first of the two preceding examples does not couple the code to Spring. Destruction Callbacks Implementing the org.springframework.beans.factory.DisposableBean interface lets a bean get a callback when the container that contains it is destroyed. The DisposableBean interface specifies a single method: void destroy() throws Exception; We recommend that you do not use the DisposableBean callback interface, because it unnecessarily couples the code to Spring. Alternatively, we suggest using the @PreDestroy annotation or specifying a generic method that is supported by bean definitions. With XML-based configuration metadata, you can use the destroy-method attribute on the . With Java configuration, you can use the destroyMethod attribute of @Bean. See Receiving Lifecycle Callbacks. Consider the following definition: Java public class ExampleBean {   public void cleanup() {   // do some destruction work (like releasing pooled connections)   } } Kotlin class ExampleBean {   fun cleanup() {   // do some destruction work (like releasing pooled connections)   } } The preceding definition has almost exactly the same effect as the following definition: Java public class AnotherExampleBean implements DisposableBean {   @Override   public void destroy() {   // do some destruction work (like releasing pooled connections)   } } Kotlin class AnotherExampleBean : DisposableBean {   override fun destroy() {   // do some destruction work (like releasing pooled connections)   } } However, the first of the two preceding definitions does not couple the code to Spring. You can assign the destroy-method attribute of a element a special (inferred) value, which instructs Spring to automatically detect a public close or shutdown method on the specific bean class. (Any class that implements java.lang.AutoCloseable or java.io.Closeable would therefore match.) You can  also set this special (inferred) value on the default-destroy-method attribute of a element to apply this behavior to an entire set of beans (see Default Initialization and Destroy Methods). Note that this is the default behavior with Java configuration. Default Initialization and Destroy Methods When you write initialization and destroy method callbacks that do not use the Spring-specific InitializingBean and DisposableBean callback interfaces, you typically write methods with names such as init(), initialize(), dispose(), and so on. Ideally, the names of such lifecycle callback methods are standardized across a project so that all developers use the same method names and ensure consistency. You can configure the Spring container to “look” for named initialization and destroy callback method names on every bean. This means that you, as an application developer, can write your application classes and use an initialization callback called init(), without having to configure an init-method="init" attribute with each bean definition. The Spring IoC container calls that method when the bean is created (and in accordance with the standard lifecycle callback contract described previously). This feature also enforces a consistent naming convention for initialization and destroy method callbacks. Suppose that your initialization callback methods are named init() and your destroy callback methods are named destroy(). Your class then resembles the class in the following example: Java public class DefaultBlogService implements BlogService {   private BlogDao blogDao;   public void setBlogDao(BlogDao blogDao) {   this.blogDao = blogDao;   }   // this is (unsurprisingly) the initialization callback method   public void init() {   if (this.blogDao == null) {   throw new IllegalStateException("The [blogDao] property must be set.");   }   } } Kotlin class DefaultBlogService : BlogService {   private var blogDao: BlogDao? = null   // this is (unsurprisingly) the initialization callback method   fun init() {   if (blogDao == null) {   throw IllegalStateException("The [blogDao] property must be set.")   }   } } You could then use that class in a bean resembling the following:       The presence of the default-init-method attribute on the top-level element attribute causes the Spring IoC container to recognize a method called init on the bean class as the initialization method callback. When a bean is created and assembled, if the bean class has such a method, it is invoked at the appropriate time. You can configure destroy method callbacks similarly (in XML, that is) by using the default- destroy-method attribute on the top-level element. Where existing bean classes already have callback methods that are named at variance with the convention, you can override the default by specifying (in XML, that is) the method name by using the init-method and destroy-method attributes of the itself. The Spring container guarantees that a configured initialization callback is called immediately after a bean is supplied with all dependencies. Thus, the initialization callback is called on the raw bean reference, which means that AOP interceptors and so forth are not yet applied to the bean. A target bean is fully created first and then an AOP proxy (for example) with its interceptor chain is applied. If the target bean and the proxy are defined separately, your code can even interact with the raw target bean, bypassing the proxy. Hence, it would be inconsistent to apply the interceptors to the init method, because doing so would couple the lifecycle of the target bean to its proxy or interceptors and leave strange semantics when your code interacts directly with the raw target bean. ================================================ FILE: spring-ai-client-chat/src/test/resources/user-prompt.txt ================================================ my question ================================================ FILE: spring-ai-commons/pom.xml ================================================ 4.0.0 org.springframework.ai spring-ai-parent 2.0.0-SNAPSHOT spring-ai-commons jar Spring AI Commons Common classes used across Spring AI https://github.com/spring-projects/spring-ai https://github.com/spring-projects/spring-ai scm:git:git://github.com/spring-projects/spring-ai.git scm:git:ssh://git@github.com/spring-projects/spring-ai.git org.springframework spring-context io.micrometer micrometer-core io.micrometer context-propagation org.slf4j slf4j-api true io.micrometer micrometer-tracing true tools.jackson.core jackson-databind org.jetbrains.kotlin kotlin-stdlib true org.jetbrains.kotlin kotlin-reflect true com.knuddels jtokkit ${jtokkit.version} org.springframework.boot spring-boot-starter-test test tools.jackson.module jackson-module-kotlin test ================================================ FILE: spring-ai-commons/src/main/java/org/springframework/ai/content/Content.java ================================================ /* * Copyright 2023-present the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * https://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ package org.springframework.ai.content; import java.util.Map; import org.jspecify.annotations.Nullable; /** * Data structure that contains content and metadata.

Spring Framework Overview Spring makes it easy to create Java enterprise applications. It provides everything you need to embrace the Java language in an enterprise environment, with support for Groovy and Kotlin as alternative languages on the JVM, and with the flexibility to create many kinds of architectures depending on an application’s needs. As of Spring Framework 5.1, Spring requires JDK 8+ (Java SE 8+) and provides out-of-the-box support for JDK 11 LTS. Java SE 8 update 60 is suggested as the minimum patch release for Java 8, but it is generally recommended to use a recent patch release. Spring supports a wide range of application scenarios. In a large enterprise, applications often exist for a long time and have to run on a JDK and application server whose upgrade cycle is beyond developer control. Others may run as a single jar with the server embedded, possibly in a cloud environment. Yet others may be standalone applications (such as batch or integration workloads) that do not need a server. Spring is open source. It has a large and active community that provides continuous feedback based on a diverse range of real-world use cases. This has helped Spring to successfully evolve over a very long time. 1.1. What We Mean by "Spring" The term "Spring" means different things in different contexts. It can be used to refer to the Spring Framework project itself, which is where it all started. Over time, other Spring projects have been built on top of the Spring Framework. Most often, when people say "Spring", they mean the entire family of projects. This reference documentation focuses on the foundation: the Spring Framework itself. The Spring Framework is divided into modules. Applications can choose which modules they need. At the heart are the modules of the core container, including a configuration model and a dependency injection mechanism. Beyond that, the Spring Framework provides foundational support for different application architectures, including messaging, transactional data and persistence, and web. It also includes the Servlet-based Spring MVC web framework and, in parallel, the Spring WebFlux reactive web framework. A note about modules: Spring’s framework jars allow for deployment to JDK 9’s module path ("Jigsaw"). For use in Jigsaw-enabled applications, the Spring Framework 5 jars come with "Automatic-Module-Name" manifest entries which define stable language-level module names ("spring.core", "spring.context", etc.) independent from jar artifact names (the jars follow the same naming pattern with "-" instead of ".", e.g. "spring-core" and "spring-context"). Of course, Spring’s framework jars keep working fine on the classpath on both JDK 8 and 9+. 1.2. History of Spring and the Spring Framework Spring came into being in 2003 as a response to the complexity of the early J2EE specifications. While some consider Java EE and its modern-day successor Jakarta EE to be in competition with Spring, they are in fact complementary. The Spring programming model does not embrace the Jakarta EE platform specification; rather, it integrates with carefully selected individual specifications from the traditional EE umbrella: • Servlet API (JSR 340) • WebSocket API (JSR 356) • Concurrency Utilities (JSR 236) • JSON Binding API (JSR 367) • Bean Validation (JSR 303) • JPA (JSR 338) • JMS (JSR 914) • as well as JTA/JCA setups for transaction coordination, if necessary. The Spring Framework also supports the Dependency Injection (JSR 330) and Common Annotations (JSR 250) specifications, which application developers may choose to use instead of the Spring- specific mechanisms provided by the Spring Framework. Originally, those were based on common javax packages. As of Spring Framework 6.0, Spring has been upgraded to the Jakarta EE 9 level (e.g. Servlet 5.0+, JPA 3.0+), based on the jakarta namespace instead of the traditional javax packages. With EE 9 as the minimum and EE 10 supported already, Spring is prepared to provide out-of-the-box support for the further evolution of the Jakarta EE APIs. Spring Framework 6.0 is fully compatible with Tomcat 10.1, Jetty 11 and Undertow 2.3 as web servers, and also with Hibernate ORM 6.1. Over time, the role of Java/Jakarta EE in application development has evolved. In the early days of J2EE and Spring, applications were created to be deployed to an application server. Today, with the help of Spring Boot, applications are created in a devops- and cloud-friendly way, with the Servlet container embedded and trivial to change. As of Spring Framework 5, a WebFlux application does not even use the Servlet API directly and can run on servers (such as Netty) that are not Servlet containers. Spring continues to innovate and to evolve. Beyond the Spring Framework, there are other projects, such as Spring Boot, Spring Security, Spring Data, Spring Cloud, Spring Batch, among others. It’s important to remember that each project has its own source code repository, issue tracker, and release cadence. See spring.io/projects for the complete list of Spring projects. 1.3. Design Philosophy When you learn about a framework, it’s important to know not only what it does but what principles it follows. Here are the guiding principles of the Spring Framework: • Provide choice at every level. Spring lets you defer design decisions as late as possible. For example, you can switch persistence providers through configuration without changing your code. The same is true for many other infrastructure concerns and integration with third-party APIs. • Accommodate diverse perspectives. Spring embraces flexibility and is not opinionated about how things should be done. It supports a wide range of application needs with different perspectives. • Maintain strong backward compatibility. Spring’s evolution has been carefully managed to force few breaking changes between versions. Spring supports a carefully chosen range of JDK versions and third-party libraries to facilitate maintenance of applications and libraries that depend on Spring. • Care about API design. The Spring team puts a lot of thought and time into making APIs that are intuitive and that hold up across many versions and many years. • Set high standards for code quality. The Spring Framework puts a strong emphasis on meaningful, current, and accurate javadoc. It is one of very few projects that can claim clean code structure with no circular dependencies between packages. 1.4. Feedback and Contributions For how-to questions or diagnosing or debugging issues, we suggest using Stack Overflow. Click here for a list of the suggested tags to use on Stack Overflow. If you’re fairly certain that there is a problem in the Spring Framework or would like to suggest a feature, please use the GitHub Issues. If you have a solution in mind or a suggested fix, you can submit a pull request on Github. However, please keep in mind that, for all but the most trivial issues, we expect a ticket to be filed in the issue tracker, where discussions take place and leave a record for future reference. For more details see the guidelines at the CONTRIBUTING, top-level project page. 1.5. Getting Started If you are just getting started with Spring, you may want to begin using the Spring Framework by creating a Spring Boot-based application. Spring Boot provides a quick (and opinionated) way to create a production-ready Spring-based application. It is based on the Spring Framework, favors convention over configuration, and is designed to get you up and running as quickly as possible. You can use start.spring.io to generate a basic project or follow one of the "Getting Started" guides, such as Getting Started Building a RESTful Web Service. As well as being easier to digest, these guides are very task focused, and most of them are based on Spring Boot. They also cover other projects from the Spring portfolio that you might want to consider when solving a particular problem. Chapter 2. Core Technologies This part of the reference documentation covers all the technologies that are absolutely integral to the Spring Framework. Foremost amongst these is the Spring Framework’s Inversion of Control (IoC) container. A thorough treatment of the Spring Framework’s IoC container is closely followed by comprehensive coverage of Spring’s Aspect-Oriented Programming (AOP) technologies. The Spring Framework has its own AOP framework, which is conceptually easy to understand and which successfully addresses the 80% sweet spot of AOP requirements in Java enterprise programming. Coverage of Spring’s integration with AspectJ (currently the richest — in terms of features — and certainly most mature AOP implementation in the Java enterprise space) is also provided. AOT processing can be used to optimize your application ahead-of-time. It is typically used for native image deployment using GraalVM. 2.1. The IoC Container This chapter covers Spring’s Inversion of Control (IoC) container. 2.1.1. Introduction to the Spring IoC Container and Beans This chapter covers the Spring Framework implementation of the Inversion of Control (IoC) principle. IoC is also known as dependency injection (DI). It is a process whereby objects define their dependencies (that is, the other objects they work with) only through constructor arguments, arguments to a factory method, or properties that are set on the object instance after it is constructed or returned from a factory method. The container then injects those dependencies when it creates the bean. This process is fundamentally the inverse (hence the name, Inversion of Control) of the bean itself controlling the instantiation or location of its dependencies by using direct construction of classes or a mechanism such as the Service Locator pattern. The org.springframework.beans and org.springframework.context packages are the basis for Spring Framework’s IoC container. The BeanFactory interface provides an advanced configuration mechanism capable of managing any type of object. ApplicationContext is a sub-interface of BeanFactory. It adds: • Easier integration with Spring’s AOP features • Message resource handling (for use in internationalization) • Event publication • Application-layer specific contexts such as the WebApplicationContext for use in web applications. In short, the BeanFactory provides the configuration framework and basic functionality, and the ApplicationContext adds more enterprise-specific functionality. The ApplicationContext is a complete superset of the BeanFactory and is used exclusively in this chapter in descriptions of Spring’s IoC container. For more information on using the BeanFactory instead of the ApplicationContext, see the section covering the BeanFactory API. In Spring, the objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your application. Beans, and the dependencies among them, are reflected in the configuration metadata used by a container. 2.1.2. Container Overview The org.springframework.context.ApplicationContext interface represents the Spring IoC container and is responsible for instantiating, configuring, and assembling the beans. The container gets its instructions on what objects to instantiate, configure, and assemble by reading configuration metadata. The configuration metadata is represented in XML, Java annotations, or Java code. It lets you express the objects that compose your application and the rich interdependencies between those objects. Several implementations of the ApplicationContext interface are supplied with Spring. In stand- alone applications, it is common to create an instance of ClassPathXmlApplicationContext or FileSystemXmlApplicationContext. While XML has been the traditional format for defining configuration metadata, you can instruct the container to use Java annotations or code as the metadata format by providing a small amount of XML configuration to declaratively enable support for these additional metadata formats. In most application scenarios, explicit user code is not required to instantiate one or more instances of a Spring IoC container. For example, in a web application scenario, a simple eight (or so) lines of boilerplate web descriptor XML in the web.xml file of the application typically suffices (see Convenient ApplicationContext Instantiation for Web Applications). If you use the Spring Tools for Eclipse (an Eclipse-powered development environment), you can easily create this boilerplate configuration with a few mouse clicks or keystrokes. The following diagram shows a high-level view of how Spring works. Your application classes are combined with configuration metadata so that, after the ApplicationContext is created and initialized, you have a fully configured and executable system or application. Figure 1. The Spring IoC container Configuration Metadata As the preceding diagram shows, the Spring IoC container consumes a form of configuration metadata. This configuration metadata represents how you, as an application developer, tell the Spring container to instantiate, configure, and assemble the objects in your application. Configuration metadata is traditionally supplied in a simple and intuitive XML format, which is what most of this chapter uses to convey key concepts and features of the Spring IoC container. XML-based metadata is not the only allowed form of configuration metadata. The Spring IoC container itself is totally decoupled from the format in which this  configuration metadata is actually written. These days, many developers choose Java-based configuration for their Spring applications. For information about using other forms of metadata with the Spring container, see: • Annotation-based configuration: Spring 2.5 introduced support for annotation-based configuration metadata. • Java-based configuration: Starting with Spring 3.0, many features provided by the Spring JavaConfig project became part of the core Spring Framework. Thus, you can define beans external to your application classes by using Java rather than XML files. To use these new features, see the @Configuration, @Bean, @Import, and @DependsOn annotations. Spring configuration consists of at least one and typically more than one bean definition that the container must manage. XML-based configuration metadata configures these beans as elements inside a top-level element. Java configuration typically uses @Bean-annotated methods within a @Configuration class. These bean definitions correspond to the actual objects that make up your application. Typically, you define service layer objects, data access objects (DAOs), presentation objects such as Struts Action instances, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so forth. Typically, one does not configure fine-grained domain objects in the container, because it is usually the responsibility of DAOs and business logic to create and load domain objects. However, you can use Spring’s integration with AspectJ to configure objects that have been created outside the control of an IoC container. See Using AspectJ to dependency-inject domain objects with Spring. The following example shows the basic structure of XML-based configuration metadata:   ① ②             ① The id attribute is a string that identifies the individual bean definition. ② The class attribute defines the type of the bean and uses the fully qualified classname. The value of the id attribute refers to collaborating objects. The XML for referring to collaborating objects is not shown in this example. See Dependencies for more information. Instantiating a Container The location path or paths supplied to an ApplicationContext constructor are resource strings that let the container load configuration metadata from a variety of external resources, such as the local file system, the Java CLASSPATH, and so on. Java ApplicationContext context = new ClassPathXmlApplicationContext("services.xml", "daos.xml"); Kotlin val context = ClassPathXmlApplicationContext("services.xml", "daos.xml") After you learn about Spring’s IoC container, you may want to know more about Spring’s Resource abstraction (as described in Resources), which provides a  convenient mechanism for reading an InputStream from locations defined in a URI syntax. In particular, Resource paths are used to construct applications contexts, as described in Application Contexts and Resource Paths. The following example shows the service layer objects (services.xml) configuration file:               The following example shows the data access objects daos.xml file:               In the preceding example, the service layer consists of the PetStoreServiceImpl class and two data access objects of the types JpaAccountDao and JpaItemDao (based on the JPA Object-Relational Mapping standard). The property name element refers to the name of the JavaBean property, and the ref element refers to the name of another bean definition. This linkage between id and ref elements expresses the dependency between collaborating objects. For details of configuring an object’s dependencies, see Dependencies. Composing XML-based Configuration Metadata It can be useful to have bean definitions span multiple XML files. Often, each individual XML configuration file represents a logical layer or module in your architecture. You can use the application context constructor to load bean definitions from all these XML fragments. This constructor takes multiple Resource locations, as was shown in the previous section. Alternatively, use one or more occurrences of the element to load bean definitions from another file or files. The following example shows how to do so:           In the preceding example, external bean definitions are loaded from three files: services.xml, messageSource.xml, and themeSource.xml. All location paths are relative to the definition file doing the importing, so services.xml must be in the same directory or classpath location as the file doing the importing, while messageSource.xml and themeSource.xml must be in a resources location below the location of the importing file. As you can see, a leading slash is ignored. However, given that these paths are relative, it is better form not to use the slash at all. The contents of the files being imported, including the top level element, must be valid XML bean definitions, according to the Spring Schema. It is possible, but not recommended, to reference files in parent directories using a relative "../" path. Doing so creates a dependency on a file that is outside the current application. In particular, this reference is not recommended for classpath: URLs (for example, classpath:../services.xml), where the runtime resolution process chooses the “nearest” classpath root and then looks into its parent directory. Classpath configuration changes may lead to the choice of a different, incorrect directory.  You can always use fully qualified resource locations instead of relative paths: for example, file:C:/config/services.xml or classpath:/config/services.xml. However, be aware that you are coupling your application’s configuration to specific absolute locations. It is generally preferable to keep an indirection for such absolute locations — for example, through "${…}" placeholders that are resolved against JVM system properties at runtime. The namespace itself provides the import directive feature. Further configuration features beyond plain bean definitions are available in a selection of XML namespaces provided by Spring — for example, the context and util namespaces. The Groovy Bean Definition DSL As a further example for externalized configuration metadata, bean definitions can also be expressed in Spring’s Groovy Bean Definition DSL, as known from the Grails framework. Typically, such configuration live in a ".groovy" file with the structure shown in the following example: beans {   dataSource(BasicDataSource) {   driverClassName = "org.hsqldb.jdbcDriver"   url = "jdbc:hsqldb:mem:grailsDB"   username = "sa"   password = ""   settings = [mynew:"setting"]   }   sessionFactory(SessionFactory) {   dataSource = dataSource   }   myService(MyService) {   nestedBean = { AnotherBean bean ->   dataSource = dataSource   }   } } This configuration style is largely equivalent to XML bean definitions and even supports Spring’s XML configuration namespaces. It also allows for importing XML bean definition files through an importBeans directive. Using the Container The ApplicationContext is the interface for an advanced factory capable of maintaining a registry of different beans and their dependencies. By using the method T getBean(String name, Class requiredType), you can retrieve instances of your beans. The ApplicationContext lets you read bean definitions and access them, as the following example shows: Java // create and configure beans ApplicationContext context = new ClassPathXmlApplicationContext("services.xml", "daos.xml"); // retrieve configured instance PetStoreService service = context.getBean("petStore", PetStoreService.class); // use configured instance List userList = service.getUsernameList(); Kotlin import org.springframework.beans.factory.getBean // create and configure beans val context = ClassPathXmlApplicationContext("services.xml", "daos.xml") // retrieve configured instance val service = context.getBean("petStore") // use configured instance var userList = service.getUsernameList() With Groovy configuration, bootstrapping looks very similar. It has a different context implementation class which is Groovy-aware (but also understands XML bean definitions). The following example shows Groovy configuration: Java ApplicationContext context = new GenericGroovyApplicationContext("services.groovy", "daos.groovy"); Kotlin val context = GenericGroovyApplicationContext("services.groovy", "daos.groovy") The most flexible variant is GenericApplicationContext in combination with reader delegates — for example, with XmlBeanDefinitionReader for XML files, as the following example shows: Java GenericApplicationContext context = new GenericApplicationContext(); new XmlBeanDefinitionReader(context).loadBeanDefinitions("services.xml", "daos.xml"); context.refresh(); Kotlin val context = GenericApplicationContext() XmlBeanDefinitionReader(context).loadBeanDefinitions("services.xml", "daos.xml") context.refresh() You can also use the GroovyBeanDefinitionReader for Groovy files, as the following example shows: Java GenericApplicationContext context = new GenericApplicationContext(); new GroovyBeanDefinitionReader(context).loadBeanDefinitions("services.groovy", "daos.groovy"); context.refresh(); Kotlin val context = GenericApplicationContext() GroovyBeanDefinitionReader(context).loadBeanDefinitions("services.groovy", "daos.groovy") context.refresh() You can mix and match such reader delegates on the same ApplicationContext, reading bean definitions from diverse configuration sources. You can then use getBean to retrieve instances of your beans. The ApplicationContext interface has a few other methods for retrieving beans, but, ideally, your application code should never use them. Indeed, your application code should have no calls to the getBean() method at all and thus have no dependency on Spring APIs at all. For example, Spring’s integration with web frameworks provides dependency injection for various web framework components such as controllers and JSF-managed beans, letting you declare a dependency on a specific bean through metadata (such as an autowiring annotation). 2.1.3. Bean Overview A Spring IoC container manages one or more beans. These beans are created with the configuration metadata that you supply to the container (for example, in the form of XML definitions). Within the container itself, these bean definitions are represented as BeanDefinition objects, which contain (among other information) the following metadata: • A package-qualified class name: typically, the actual implementation class of the bean being defined. • Bean behavioral configuration elements, which state how the bean should behave in the container (scope, lifecycle callbacks, and so forth). • References to other beans that are needed for the bean to do its work. These references are also called collaborators or dependencies. • Other configuration settings to set in the newly created object — for example, the size limit of the pool or the number of connections to use in a bean that manages a connection pool. This metadata translates to a set of properties that make up each bean definition. The following table describes these properties: Table 1. The bean definition Property Explained in… Class Instantiating Beans Name Naming Beans Scope Bean Scopes Constructor arguments Dependency Injection Properties Dependency Injection Autowiring mode Autowiring Collaborators Lazy initialization mode Lazy-initialized Beans Initialization method Initialization Callbacks Destruction method Destruction Callbacks In addition to bean definitions that contain information on how to create a specific bean, the ApplicationContext implementations also permit the registration of existing objects that are created outside the container (by users). This is done by accessing the ApplicationContext’s BeanFactory through the getBeanFactory() method, which returns the DefaultListableBeanFactory implementation. DefaultListableBeanFactory supports this registration through the registerSingleton(..) and registerBeanDefinition(..) methods. However, typical applications work solely with beans defined through regular bean definition metadata. Bean metadata and manually supplied singleton instances need to be registered as early as possible, in order for the container to properly reason about them during autowiring and other introspection steps. While overriding existing metadata and  existing singleton instances is supported to some degree, the registration of new beans at runtime (concurrently with live access to the factory) is not officially supported and may lead to concurrent access exceptions, inconsistent state in the bean container, or both. Naming Beans Every bean has one or more identifiers. These identifiers must be unique within the container that hosts the bean. A bean usually has only one identifier. However, if it requires more than one, the extra ones can be considered aliases. In XML-based configuration metadata, you use the id attribute, the name attribute, or both to specify the bean identifiers. The id attribute lets you specify exactly one id. Conventionally, these names are alphanumeric ('myBean', 'someService', etc.), but they can contain special characters as well. If you want to introduce other aliases for the bean, you can also specify them in the name attribute, separated by a comma (,), semicolon (;), or white space. As a historical note, in versions prior to Spring 3.1, the id attribute was defined as an xsd:ID type, which constrained possible characters. As of 3.1, it is defined as an xsd:string type. Note that bean id uniqueness is still enforced by the container, though no longer by XML parsers. You are not required to supply a name or an id for a bean. If you do not supply a name or id explicitly, the container generates a unique name for that bean. However, if you want to refer to that bean by name, through the use of the ref element or a Service Locator style lookup, you must provide a name. Motivations for not supplying a name are related to using inner beans and autowiring collaborators. Bean Naming Conventions The convention is to use the standard Java convention for instance field names when naming beans. That is, bean names start with a lowercase letter and are camel-cased from there. Examples of such names include accountManager, accountService, userDao, loginController, and so forth. Naming beans consistently makes your configuration easier to read and understand. Also, if you use Spring AOP, it helps a lot when applying advice to a set of beans related by name. With component scanning in the classpath, Spring generates bean names for unnamed components, following the rules described earlier: essentially, taking the simple class name and turning its initial character to lower-case. However, in the  (unusual) special case when there is more than one character and both the first and second characters are upper case, the original casing gets preserved. These are the same rules as defined by java.beans.Introspector.decapitalize (which Spring uses here). Aliasing a Bean outside the Bean Definition In a bean definition itself, you can supply more than one name for the bean, by using a combination of up to one name specified by the id attribute and any number of other names in the name attribute. These names can be equivalent aliases to the same bean and are useful for some situations, such as letting each component in an application refer to a common dependency by using a bean name that is specific to that component itself. Specifying all aliases where the bean is actually defined is not always adequate, however. It is sometimes desirable to introduce an alias for a bean that is defined elsewhere. This is commonly the case in large systems where configuration is split amongst each subsystem, with each subsystem having its own set of object definitions. In XML-based configuration metadata, you can use the element to accomplish this. The following example shows how to do so: In this case, a bean (in the same container) named fromName may also, after the use of this alias definition, be referred to as toName. For example, the configuration metadata for subsystem A may refer to a DataSource by the name of subsystemA-dataSource. The configuration metadata for subsystem B may refer to a DataSource by the name of subsystemB-dataSource. When composing the main application that uses both these subsystems, the main application refers to the DataSource by the name of myApp-dataSource. To have all three names refer to the same object, you can add the following alias definitions to the configuration metadata: Now each component and the main application can refer to the dataSource through a name that is unique and guaranteed not to clash with any other definition (effectively creating a namespace), yet they refer to the same bean. Java-configuration If you use Javaconfiguration, the @Bean annotation can be used to provide aliases. See Using the @Bean Annotation for details. Instantiating Beans A bean definition is essentially a recipe for creating one or more objects. The container looks at the recipe for a named bean when asked and uses the configuration metadata encapsulated by that bean definition to create (or acquire) an actual object. If you use XML-based configuration metadata, you specify the type (or class) of object that is to be instantiated in the class attribute of the element. This class attribute (which, internally, is a Class property on a BeanDefinition instance) is usually mandatory. (For exceptions, see Instantiation by Using an Instance Factory Method and Bean Definition Inheritance.) You can use the Class property in one of two ways: • Typically, to specify the bean class to be constructed in the case where the container itself directly creates the bean by calling its constructor reflectively, somewhat equivalent to Java code with the new operator. • To specify the actual class containing the static factory method that is invoked to create the object, in the less common case where the container invokes a static factory method on a class to create the bean. The object type returned from the invocation of the static factory method may be the same class or another class entirely. Nested class names If you want to configure a bean definition for a nested class, you may use either the binary name or the source name of the nested class. For example, if you have a class called SomeThing in the com.example package, and this SomeThing class has a static nested class called OtherThing, they can be separated by a dollar sign ($) or a dot (.). So the value of the class attribute in a bean definition would be com.example.SomeThing$OtherThing or com.example.SomeThing.OtherThing. Instantiation with a Constructor When you create a bean by the constructor approach, all normal classes are usable by and compatible with Spring. That is, the class being developed does not need to implement any specific interfaces or to be coded in a specific fashion. Simply specifying the bean class should suffice. However, depending on what type of IoC you use for that specific bean, you may need a default (empty) constructor. The Spring IoC container can manage virtually any class you want it to manage. It is not limited to managing true JavaBeans. Most Spring users prefer actual JavaBeans with only a default (no- argument) constructor and appropriate setters and getters modeled after the properties in the container. You can also have more exotic non-bean-style classes in your container. If, for example, you need to use a legacy connection pool that absolutely does not adhere to the JavaBean specification, Spring can manage it as well. With XML-based configuration metadata you can specify your bean class as follows: For details about the mechanism for supplying arguments to the constructor (if required) and setting object instance properties after the object is constructed, see Injecting Dependencies. Instantiation with a Static Factory Method When defining a bean that you create with a static factory method, use the class attribute to specify the class that contains the static factory method and an attribute named factory-method to specify the name of the factory method itself. You should be able to call this method (with optional arguments, as described later) and return a live object, which subsequently is treated as if it had been created through a constructor. One use for such a bean definition is to call static factories in legacy code. The following bean definition specifies that the bean will be created by calling a factory method. The definition does not specify the type (class) of the returned object, but rather the class containing the factory method. In this example, the createInstance() method must be a static method. The following example shows how to specify a factory method: The following example shows a class that would work with the preceding bean definition: Java public class ClientService {   private static ClientService clientService = new ClientService();   private ClientService() {}   public static ClientService createInstance() {   return clientService;   } } Kotlin class ClientService private constructor() {   companion object {   private val clientService = ClientService()   @JvmStatic   fun createInstance() = clientService   } } For details about the mechanism for supplying (optional) arguments to the factory method and setting object instance properties after the object is returned from the factory, see Dependencies and Configuration in Detail. Instantiation by Using an Instance Factory Method Similar to instantiation through a static factory method, instantiation with an instance factory method invokes a non-static method of an existing bean from the container to create a new bean. To use this mechanism, leave the class attribute empty and, in the factory-bean attribute, specify the name of a bean in the current (or parent or ancestor) container that contains the instance method that is to be invoked to create the object. Set the name of the factory method itself with the factory-method attribute. The following example shows how to configure such a bean:   The following example shows the corresponding class: Java public class DefaultServiceLocator {   private static ClientService clientService = new ClientServiceImpl();   public ClientService createClientServiceInstance() {   return clientService;   } } Kotlin class DefaultServiceLocator {   companion object {   private val clientService = ClientServiceImpl()   }   fun createClientServiceInstance(): ClientService {   return clientService   } } One factory class can also hold more than one factory method, as the following example shows:   The following example shows the corresponding class: Java public class DefaultServiceLocator {   private static ClientService clientService = new ClientServiceImpl();   private static AccountService accountService = new AccountServiceImpl();   public ClientService createClientServiceInstance() {   return clientService;   }   public AccountService createAccountServiceInstance() {   return accountService;   } } Kotlin class DefaultServiceLocator {   companion object {   private val clientService = ClientServiceImpl()   private val accountService = AccountServiceImpl()   }   fun createClientServiceInstance(): ClientService {   return clientService   }   fun createAccountServiceInstance(): AccountService {   return accountService   } } This approach shows that the factory bean itself can be managed and configured through dependency injection (DI). See Dependencies and Configuration in Detail. In Spring documentation, "factory bean" refers to a bean that is configured in the Spring container and that creates objects through an instance or static factory  method. By contrast, FactoryBean (notice the capitalization) refers to a Spring- specific FactoryBean implementation class. Determining a Bean’s Runtime Type The runtime type of a specific bean is non-trivial to determine. A specified class in the bean metadata definition is just an initial class reference, potentially combined with a declared factory method or being a FactoryBean class which may lead to a different runtime type of the bean, or not being set at all in case of an instance-level factory method (which is resolved via the specified factory-bean name instead). Additionally, AOP proxying may wrap a bean instance with an interface-based proxy with limited exposure of the target bean’s actual type (just its implemented interfaces). The recommended way to find out about the actual runtime type of a particular bean is a BeanFactory.getType call for the specified bean name. This takes all of the above cases into account and returns the type of object that a BeanFactory.getBean call is going to return for the same bean name. 2.1.4. Dependencies A typical enterprise application does not consist of a single object (or bean in the Spring parlance). Even the simplest application has a few objects that work together to present what the end-user sees as a coherent application. This next section explains how you go from defining a number of bean definitions that stand alone to a fully realized application where objects collaborate to achieve a goal. Dependency Injection Dependency injection (DI) is a process whereby objects define their dependencies (that is, the other objects with which they work) only through constructor arguments, arguments to a factory method, or properties that are set on the object instance after it is constructed or returned from a factory method. The container then injects those dependencies when it creates the bean. This process is fundamentally the inverse (hence the name, Inversion of Control) of the bean itself controlling the instantiation or location of its dependencies on its own by using direct construction of classes or the Service Locator pattern. Code is cleaner with the DI principle, and decoupling is more effective when objects are provided with their dependencies. The object does not look up its dependencies and does not know the location or class of the dependencies. As a result, your classes become easier to test, particularly when the dependencies are on interfaces or abstract base classes, which allow for stub or mock implementations to be used in unit tests. DI exists in two major variants: Constructor-based dependency injection and Setter-based dependency injection. Constructor-based Dependency Injection Constructor-based DI is accomplished by the container invoking a constructor with a number of arguments, each representing a dependency. Calling a static factory method with specific arguments to construct the bean is nearly equivalent, and this discussion treats arguments to a constructor and to a static factory method similarly. The following example shows a class that can only be dependency-injected with constructor injection: Java public class SimpleMovieLister {   // the SimpleMovieLister has a dependency on a MovieFinder   private final MovieFinder movieFinder;   // a constructor so that the Spring container can inject a MovieFinder   public SimpleMovieLister(MovieFinder movieFinder) {   this.movieFinder = movieFinder;   }   // business logic that actually uses the injected MovieFinder is omitted... } Kotlin // a constructor so that the Spring container can inject a MovieFinder class SimpleMovieLister(private val movieFinder: MovieFinder) {   // business logic that actually uses the injected MovieFinder is omitted... } Notice that there is nothing special about this class. It is a POJO that has no dependencies on container specific interfaces, base classes, or annotations. Constructor Argument Resolution Constructor argument resolution matching occurs by using the argument’s type. If no potential ambiguity exists in the constructor arguments of a bean definition, the order in which the constructor arguments are defined in a bean definition is the order in which those arguments are supplied to the appropriate constructor when the bean is being instantiated. Consider the following class: Java package x.y; public class ThingOne {   public ThingOne(ThingTwo thingTwo, ThingThree thingThree) {   // ...   } } Kotlin package x.y class ThingOne(thingTwo: ThingTwo, thingThree: ThingThree) Assuming that the ThingTwo and ThingThree classes are not related by inheritance, no potential ambiguity exists. Thus, the following configuration works fine, and you do not need to specify the constructor argument indexes or types explicitly in the element.             When another bean is referenced, the type is known, and matching can occur (as was the case with the preceding example). When a simple type is used, such as true, Spring cannot determine the type of the value, and so cannot match by type without help. Consider the following class: Java package examples; public class ExampleBean {   // Number of years to calculate the Ultimate Answer   private final int years;   // The Answer to Life, the Universe, and Everything   private final String ultimateAnswer;   public ExampleBean(int years, String ultimateAnswer) {   this.years = years;   this.ultimateAnswer = ultimateAnswer;   } } Kotlin package examples class ExampleBean(   private val years: Int, // Number of years to calculate the Ultimate Answer   private val ultimateAnswer: String // The Answer to Life, the Universe, and Everything ) Constructor argument type matching In the preceding scenario, the container can use type matching with simple types if you explicitly specify the type of the constructor argument by using the type attribute, as the following example shows:     Constructor argument index You can use the index attribute to specify explicitly the index of constructor arguments, as the following example shows:     In addition to resolving the ambiguity of multiple simple values, specifying an index resolves ambiguity where a constructor has two arguments of the same type.  The index is 0-based. Constructor argument name You can also use the constructor parameter name for value disambiguation, as the following example shows:     Keep in mind that, to make this work out of the box, your code must be compiled with the debug flag enabled so that Spring can look up the parameter name from the constructor. If you cannot or do not want to compile your code with the debug flag, you can use the @ConstructorProperties JDK annotation to explicitly name your constructor arguments. The sample class would then have to look as follows: Java package examples; public class ExampleBean {   // Fields omitted   @ConstructorProperties({"years", "ultimateAnswer"})   public ExampleBean(int years, String ultimateAnswer) {   this.years = years;   this.ultimateAnswer = ultimateAnswer;   } } Kotlin package examples class ExampleBean @ConstructorProperties("years", "ultimateAnswer") constructor(val years: Int, val ultimateAnswer: String) Setter-based Dependency Injection Setter-based DI is accomplished by the container calling setter methods on your beans after invoking a no-argument constructor or a no-argument static factory method to instantiate your bean. The following example shows a class that can only be dependency-injected by using pure setter injection. This class is conventional Java. It is a POJO that has no dependencies on container specific interfaces, base classes, or annotations. Java public class SimpleMovieLister {   // the SimpleMovieLister has a dependency on the MovieFinder   private MovieFinder movieFinder;   // a setter method so that the Spring container can inject a MovieFinder   public void setMovieFinder(MovieFinder movieFinder) {   this.movieFinder = movieFinder;   }   // business logic that actually uses the injected MovieFinder is omitted... } Kotlin class SimpleMovieLister {   // a late-initialized property so that the Spring container can inject a MovieFinder   lateinit var movieFinder: MovieFinder   // business logic that actually uses the injected MovieFinder is omitted... } The ApplicationContext supports constructor-based and setter-based DI for the beans it manages. It also supports setter-based DI after some dependencies have already been injected through the constructor approach. You configure the dependencies in the form of a BeanDefinition, which you use in conjunction with PropertyEditor instances to convert properties from one format to another. However, most Spring users do not work with these classes directly (that is, programmatically) but rather with XML bean definitions, annotated components (that is, classes annotated with @Component, @Controller, and so forth), or @Bean methods in Java-based @Configuration classes. These sources are then converted internally into instances of BeanDefinition and used to load an entire Spring IoC container instance. Constructor-based or setter-based DI? Since you can mix constructor-based and setter-based DI, it is a good rule of thumb to use constructors for mandatory dependencies and setter methods or configuration methods for optional dependencies. Note that use of the @Autowired annotation on a setter method can be used to make the property be a required dependency; however, constructor injection with programmatic validation of arguments is preferable. The Spring team generally advocates constructor injection, as it lets you implement application components as immutable objects and ensures that required dependencies are not null. Furthermore, constructor-injected components are always returned to the client (calling) code in a fully initialized state. As a side note, a large number of constructor arguments is a bad code smell, implying that the class likely has too many responsibilities and should be refactored to better address proper separation of concerns. Setter injection should primarily only be used for optional dependencies that can be assigned reasonable default values within the class. Otherwise, not-null checks must be performed everywhere the code uses the dependency. One benefit of setter injection is that setter methods make objects of that class amenable to reconfiguration or re-injection later. Management through JMX MBeans is therefore a compelling use case for setter injection. Use the DI style that makes the most sense for a particular class. Sometimes, when dealing with third-party classes for which you do not have the source, the choice is made for you. For example, if a third-party class does not expose any setter methods, then constructor injection may be the only available form of DI. Dependency Resolution Process The container performs bean dependency resolution as follows: • The ApplicationContext is created and initialized with configuration metadata that describes all the beans. Configuration metadata can be specified by XML, Java code, or annotations. • For each bean, its dependencies are expressed in the form of properties, constructor arguments, or arguments to the static-factory method (if you use that instead of a normal constructor). These dependencies are provided to the bean, when the bean is actually created. • Each property or constructor argument is an actual definition of the value to set, or a reference to another bean in the container. • Each property or constructor argument that is a value is converted from its specified format to the actual type of that property or constructor argument. By default, Spring can convert a value supplied in string format to all built-in types, such as int, long, String, boolean, and so forth. The Spring container validates the configuration of each bean as the container is created. However, the bean properties themselves are not set until the bean is actually created. Beans that are singleton-scoped and set to be pre-instantiated (the default) are created when the container is created. Scopes are defined in Bean Scopes. Otherwise, the bean is created only when it is requested. Creation of a bean potentially causes a graph of beans to be created, as the bean’s dependencies and its dependencies' dependencies (and so on) are created and assigned. Note that resolution mismatches among those dependencies may show up late — that is, on first creation of the affected bean. Circular dependencies If you use predominantly constructor injection, it is possible to create an unresolvable circular dependency scenario. For example: Class A requires an instance of class B through constructor injection, and class B requires an instance of class A through constructor injection. If you configure beans for classes A and B to be injected into each other, the Spring IoC container detects this circular reference at runtime, and throws a BeanCurrentlyInCreationException. One possible solution is to edit the source code of some classes to be configured by setters rather than constructors. Alternatively, avoid constructor injection and use setter injection only. In other words, although it is not recommended, you can configure circular dependencies with setter injection. Unlike the typical case (with no circular dependencies), a circular dependency between bean A and bean B forces one of the beans to be injected into the other prior to being fully initialized itself (a classic chicken-and-egg scenario). You can generally trust Spring to do the right thing. It detects configuration problems, such as references to non-existent beans and circular dependencies, at container load-time. Spring sets properties and resolves dependencies as late as possible, when the bean is actually created. This means that a Spring container that has loaded correctly can later generate an exception when you request an object if there is a problem creating that object or one of its dependencies — for example, the bean throws an exception as a result of a missing or invalid property. This potentially delayed visibility of some configuration issues is why ApplicationContext implementations by default pre-instantiate singleton beans. At the cost of some upfront time and memory to create these beans before they are actually needed, you discover configuration issues when the ApplicationContext is created, not later. You can still override this default behavior so that singleton beans initialize lazily, rather than being eagerly pre-instantiated. If no circular dependencies exist, when one or more collaborating beans are being injected into a dependent bean, each collaborating bean is totally configured prior to being injected into the dependent bean. This means that, if bean A has a dependency on bean B, the Spring IoC container completely configures bean B prior to invoking the setter method on bean A. In other words, the bean is instantiated (if it is not a pre-instantiated singleton), its dependencies are set, and the relevant lifecycle methods (such as a configured init method or the InitializingBean callback method) are invoked. Examples of Dependency Injection The following example uses XML-based configuration metadata for setter-based DI. A small part of a Spring XML configuration file specifies some bean definitions as follows:               The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   private AnotherBean beanOne;   private YetAnotherBean beanTwo;   private int i;   public void setBeanOne(AnotherBean beanOne) {   this.beanOne = beanOne;   }   public void setBeanTwo(YetAnotherBean beanTwo) {   this.beanTwo = beanTwo;   }   public void setIntegerProperty(int i) {   this.i = i;   } } Kotlin class ExampleBean {   lateinit var beanOne: AnotherBean   lateinit var beanTwo: YetAnotherBean   var i: Int = 0 } In the preceding example, setters are declared to match against the properties specified in the XML file. The following example uses constructor-based DI:               The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   private AnotherBean beanOne;   private YetAnotherBean beanTwo;   private int i;   public ExampleBean(   AnotherBean anotherBean, YetAnotherBean yetAnotherBean, int i) {   this.beanOne = anotherBean;   this.beanTwo = yetAnotherBean;   this.i = i;   } } Kotlin class ExampleBean(   private val beanOne: AnotherBean,   private val beanTwo: YetAnotherBean,   private val i: Int) The constructor arguments specified in the bean definition are used as arguments to the constructor of the ExampleBean. Now consider a variant of this example, where, instead of using a constructor, Spring is told to call a static factory method to return an instance of the object:       The following example shows the corresponding ExampleBean class: Java public class ExampleBean {   // a private constructor   private ExampleBean(...) {   ...   }   // a static factory method; the arguments to this method can be   // considered the dependencies of the bean that is returned,   // regardless of how those arguments are actually used.   public static ExampleBean createInstance (   AnotherBean anotherBean, YetAnotherBean yetAnotherBean, int i) {   ExampleBean eb = new ExampleBean (...);   // some other operations...   return eb;   } } Kotlin class ExampleBean private constructor() {   companion object {   // a static factory method; the arguments to this method can be   // considered the dependencies of the bean that is returned,   // regardless of how those arguments are actually used.   @JvmStatic   fun createInstance(anotherBean: AnotherBean, yetAnotherBean: YetAnotherBean, i: Int): ExampleBean {   val eb = ExampleBean (...)   // some other operations...   return eb   }   } } Arguments to the static factory method are supplied by elements, exactly the same as if a constructor had actually been used. The type of the class being returned by the factory method does not have to be of the same type as the class that contains the static factory method (although, in this example, it is). An instance (non-static) factory method can be used in an essentially identical fashion (aside from the use of the factory-bean attribute instead of the class attribute), so we do not discuss those details here. Dependencies and Configuration in Detail As mentioned in the previous section, you can define bean properties and constructor arguments as references to other managed beans (collaborators) or as values defined inline. Spring’s XML-based configuration metadata supports sub-element types within its and elements for this purpose. Straight Values (Primitives, Strings, and so on) The value attribute of the element specifies a property or constructor argument as a human-readable string representation. Spring’s conversion service is used to convert these values from a String to the actual type of the property or argument. The following example shows various values being set:           The following example uses the p-namespace for even more succinct XML configuration:   The preceding XML is more succinct. However, typos are discovered at runtime rather than design time, unless you use an IDE (such as IntelliJ IDEA or the Spring Tools for Eclipse) that supports automatic property completion when you create bean definitions. Such IDE assistance is highly recommended. You can also configure a java.util.Properties instance, as follows:         jdbc.driver.className=com.mysql.jdbc.Driver   jdbc.url=jdbc:mysql://localhost:3306/mydb     The Spring container converts the text inside the element into a java.util.Properties instance by using the JavaBeans PropertyEditor mechanism. This is a nice shortcut, and is one of a few places where the Spring team do favor the use of the nested element over the value attribute style. The idref element The idref element is simply an error-proof way to pass the id (a string value - not a reference) of another bean in the container to a or element. The following example shows how to use it:       The preceding bean definition snippet is exactly equivalent (at runtime) to the following snippet:   The first form is preferable to the second, because using the idref tag lets the container validate at deployment time that the referenced, named bean actually exists. In the second variation, no validation is performed on the value that is passed to the targetName property of the client bean. Typos are only discovered (with most likely fatal results) when the client bean is actually instantiated. If the client bean is a prototype bean, this typo and the resulting exception may only be discovered long after the container is deployed. The local attribute on the idref element is no longer supported in the 4.0 beans XSD, since it does not provide value over a regular bean reference any more.  Change your existing idref local references to idref bean when upgrading to the 4.0 schema. A common place (at least in versions earlier than Spring 2.0) where the element brings value is in the configuration of AOP interceptors in a ProxyFactoryBean bean definition. Using elements when you specify the interceptor names prevents you from misspelling an interceptor ID. References to Other Beans (Collaborators) The ref element is the final element inside a or definition element. Here, you set the value of the specified property of a bean to be a reference to another bean (a collaborator) managed by the container. The referenced bean is a dependency of the bean whose property is to be set, and it is initialized on demand as needed before the property is set. (If the collaborator is a singleton bean, it may already be initialized by the container.) All references are ultimately a reference to another object. Scoping and validation depend on whether you specify the ID or name of the other object through the bean or parent attribute. Specifying the target bean through the bean attribute of the tag is the most general form and allows creation of a reference to any bean in the same container or parent container, regardless of whether it is in the same XML file. The value of the bean attribute may be the same as the id attribute of the target bean or be the same as one of the values in the name attribute of the target bean. The following example shows how to use a ref element: Specifying the target bean through the parent attribute creates a reference to a bean that is in a parent container of the current container. The value of the parent attribute may be the same as either the id attribute of the target bean or one of the values in the name attribute of the target bean. The target bean must be in a parent container of the current one. You should use this bean reference variant mainly when you have a hierarchy of containers and you want to wrap an existing bean in a parent container with a proxy that has the same name as the parent bean. The following pair of listings shows how to use the parent attribute:     class="org.springframework.aop.framework.ProxyFactoryBean">         The local attribute on the ref element is no longer supported in the 4.0 beans XSD,  since it does not provide value over a regular bean reference any more. Change your existing ref local references to ref bean when upgrading to the 4.0 schema. Inner Beans A element inside the or elements defines an inner bean, as the following example shows:               An inner bean definition does not require a defined ID or name. If specified, the container does not use such a value as an identifier. The container also ignores the scope flag on creation, because inner beans are always anonymous and are always created with the outer bean. It is not possible to access inner beans independently or to inject them into collaborating beans other than into the enclosing bean. As a corner case, it is possible to receive destruction callbacks from a custom scope — for example, for a request-scoped inner bean contained within a singleton bean. The creation of the inner bean instance is tied to its containing bean, but destruction callbacks let it participate in the request scope’s lifecycle. This is not a common scenario. Inner beans typically simply share their containing bean’s scope. Collections The , , , and elements set the properties and arguments of the Java Collection types List, Set, Map, and Properties, respectively. The following example shows how to use them:         administrator@example.org   support@example.org   development@example.org             a list element followed by a reference                             just some string       The value of a map key or value, or a set value, can also be any of the following elements: bean | ref | idref | list | set | map | props | value | null Collection Merging The Spring container also supports merging collections. An application developer can define a parent , , or element and have child , , or elements inherit and override values from the parent collection. That is, the child collection’s values are the result of merging the elements of the parent and child collections, with the child’s collection elements overriding values specified in the parent collection. This section on merging discusses the parent-child bean mechanism. Readers unfamiliar with parent and child bean definitions may wish to read the relevant section before continuing. The following example demonstrates collection merging:         administrator@example.com   support@example.com                 sales@example.com   support@example.co.uk       Notice the use of the merge=true attribute on the element of the adminEmails property of the child bean definition. When the child bean is resolved and instantiated by the container, the resulting instance has an adminEmails Properties collection that contains the result of merging the child’s adminEmails collection with the parent’s adminEmails collection. The following listing shows the result: administrator=administrator@example.com sales=sales@example.com support=support@example.co.uk The child Properties collection’s value set inherits all property elements from the parent , and the child’s value for the support value overrides the value in the parent collection. This merging behavior applies similarly to the , , and collection types. In the specific case of the element, the semantics associated with the List collection type (that is, the notion of an ordered collection of values) is maintained. The parent’s values precede all of the child list’s values. In the case of the Map, Set, and Properties collection types, no ordering exists. Hence, no ordering semantics are in effect for the collection types that underlie the associated Map, Set, and Properties implementation types that the container uses internally. Limitations of Collection Merging You cannot merge different collection types (such as a Map and a List). If you do attempt to do so, an appropriate Exception is thrown. The merge attribute must be specified on the lower, inherited, child definition. Specifying the merge attribute on a parent collection definition is redundant and does not result in the desired merging. Strongly-typed collection Thanks to Java’s support for generic types, you can use strongly typed collections. That is, it is possible to declare a Collection type such that it can only contain (for example) String elements. If you use Spring to dependency-inject a strongly-typed Collection into a bean, you can take advantage of Spring’s type-conversion support such that the elements of your strongly-typed Collection instances are converted to the appropriate type prior to being added to the Collection. The following Java class and bean definition show how to do so: Java public class SomeClass {   private Map accounts;   public void setAccounts(Map accounts) {   this.accounts = accounts;   } } Kotlin class SomeClass {   lateinit var accounts: Map }                   When the accounts property of the something bean is prepared for injection, the generics information about the element type of the strongly-typed Map is available by reflection. Thus, Spring’s type conversion infrastructure recognizes the various value elements as being of type Float, and the string values (9.99, 2.75, and 3.99) are converted into an actual Float type. Null and Empty String Values Spring treats empty arguments for properties and the like as empty Strings. The following XML- based configuration metadata snippet sets the email property to the empty String value ("").   The preceding example is equivalent to the following Java code: Java exampleBean.setEmail(""); Kotlin exampleBean.email = "" The element handles null values. The following listing shows an example:       The preceding configuration is equivalent to the following Java code: Java exampleBean.setEmail(null); Kotlin exampleBean.email = null XML Shortcut with the p-namespace The p-namespace lets you use the bean element’s attributes (instead of nested elements) to describe your property values collaborating beans, or both. Spring supports extensible configuration formats with namespaces, which are based on an XML Schema definition. The beans configuration format discussed in this chapter is defined in an XML Schema document. However, the p-namespace is not defined in an XSD file and exists only in the core of Spring. The following example shows two XML snippets (the first uses standard XML format and the second uses the p-namespace) that resolve to the same result:         The example shows an attribute in the p-namespace called email in the bean definition. This tells Spring to include a property declaration. As previously mentioned, the p-namespace does not have a schema definition, so you can set the name of the attribute to the property name. This next example includes two more bean definitions that both have a reference to another bean:                 This example includes not only a property value using the p-namespace but also uses a special format to declare property references. Whereas the first bean definition uses to create a reference from bean john to bean jane, the second bean definition uses p:spouse-ref="jane" as an attribute to do the exact same thing. In this case, spouse is the property name, whereas the -ref part indicates that this is not a straight value but rather a reference to another bean. The p-namespace is not as flexible as the standard XML format. For example, the format for declaring property references clashes with properties that end in Ref,  whereas the standard XML format does not. We recommend that you choose your approach carefully and communicate this to your team members to avoid producing XML documents that use all three approaches at the same time. XML Shortcut with the c-namespace Similar to the XML Shortcut with the p-namespace, the c-namespace, introduced in Spring 3.1, allows inlined attributes for configuring the constructor arguments rather then nested constructor- arg elements. The following example uses the c: namespace to do the same thing as the from Constructor-based Dependency Injection:                     The c: namespace uses the same conventions as the p: one (a trailing -ref for bean references) for setting the constructor arguments by their names. Similarly, it needs to be declared in the XML file even though it is not defined in an XSD schema (it exists inside the Spring core). For the rare cases where the constructor argument names are not available (usually if the bytecode was compiled without debugging information), you can use fallback to the argument indexes, as follows: Due to the XML grammar, the index notation requires the presence of the leading _, as XML attribute names cannot start with a number (even though some IDEs  allow it). A corresponding index notation is also available for elements but not commonly used since the plain order of declaration is usually sufficient there. In practice, the constructor resolution mechanism is quite efficient in matching arguments, so unless you really need to, we recommend using the name notation throughout your configuration. Compound Property Names You can use compound or nested property names when you set bean properties, as long as all components of the path except the final property name are not null. Consider the following bean definition:   The something bean has a fred property, which has a bob property, which has a sammy property, and that final sammy property is being set to a value of 123. In order for this to work, the fred property of something and the bob property of fred must not be null after the bean is constructed. Otherwise, a NullPointerException is thrown. Using depends-on If a bean is a dependency of another bean, that usually means that one bean is set as a property of another. Typically you accomplish this with the element in XML-based configuration metadata. However, sometimes dependencies between beans are less direct. An example is when a static initializer in a class needs to be triggered, such as for database driver registration. The depends-on attribute can explicitly force one or more beans to be initialized before the bean using this element is initialized. The following example uses the depends-on attribute to express a dependency on a single bean: To express a dependency on multiple beans, supply a list of bean names as the value of the depends- on attribute (commas, whitespace, and semicolons are valid delimiters):   The depends-on attribute can specify both an initialization-time dependency and, in the case of singleton beans only, a corresponding destruction-time dependency.  Dependent beans that define a depends-on relationship with a given bean are destroyed first, prior to the given bean itself being destroyed. Thus, depends-on can also control shutdown order. Lazy-initialized Beans By default, ApplicationContext implementations eagerly create and configure all singleton beans as part of the initialization process. Generally, this pre-instantiation is desirable, because errors in the configuration or surrounding environment are discovered immediately, as opposed to hours or even days later. When this behavior is not desirable, you can prevent pre-instantiation of a singleton bean by marking the bean definition as being lazy-initialized. A lazy-initialized bean tells the IoC container to create a bean instance when it is first requested, rather than at startup. In XML, this behavior is controlled by the lazy-init attribute on the element, as the following example shows: When the preceding configuration is consumed by an ApplicationContext, the lazy bean is not eagerly pre-instantiated when the ApplicationContext starts, whereas the not.lazy bean is eagerly pre-instantiated. However, when a lazy-initialized bean is a dependency of a singleton bean that is not lazy- initialized, the ApplicationContext creates the lazy-initialized bean at startup, because it must satisfy the singleton’s dependencies. The lazy-initialized bean is injected into a singleton bean elsewhere that is not lazy-initialized. You can also control lazy-initialization at the container level by using the default-lazy-init attribute on the element, as the following example shows:   Autowiring Collaborators The Spring container can autowire relationships between collaborating beans. You can let Spring resolve collaborators (other beans) automatically for your bean by inspecting the contents of the ApplicationContext. Autowiring has the following advantages: • Autowiring can significantly reduce the need to specify properties or constructor arguments. (Other mechanisms such as a bean template discussed elsewhere in this chapter are also valuable in this regard.) • Autowiring can update a configuration as your objects evolve. For example, if you need to add a dependency to a class, that dependency can be satisfied automatically without you needing to modify the configuration. Thus autowiring can be especially useful during development, without negating the option of switching to explicit wiring when the code base becomes more stable. When using XML-based configuration metadata (see Dependency Injection), you can specify the autowire mode for a bean definition with the autowire attribute of the element. The autowiring functionality has four modes. You specify autowiring per bean and can thus choose which ones to autowire. The following table describes the four autowiring modes: Table 2. Autowiring modes Mode Explanation no (Default) No autowiring. Bean references must be defined by ref elements. Changing the default setting is not recommended for larger deployments, because specifying collaborators explicitly gives greater control and clarity. To some extent, it documents the structure of a system. byName Autowiring by property name. Spring looks for a bean with the same name as the property that needs to be autowired. For example, if a bean definition is set to autowire by name and it contains a master property (that is, it has a setMaster(..) method), Spring looks for a bean definition named master and uses it to set the property. byType Lets a property be autowired if exactly one bean of the property type exists in the container. If more than one exists, a fatal exception is thrown, which indicates that you may not use byType autowiring for that bean. If there are no matching beans, nothing happens (the property is not set). constructor Analogous to byType but applies to constructor arguments. If there is not exactly one bean of the constructor argument type in the container, a fatal error is raised. With byType or constructor autowiring mode, you can wire arrays and typed collections. In such cases, all autowire candidates within the container that match the expected type are provided to satisfy the dependency. You can autowire strongly-typed Map instances if the expected key type is String. An autowired Map instance’s values consist of all bean instances that match the expected type, and the Map instance’s keys contain the corresponding bean names. Limitations and Disadvantages of Autowiring Autowiring works best when it is used consistently across a project. If autowiring is not used in general, it might be confusing to developers to use it to wire only one or two bean definitions. Consider the limitations and disadvantages of autowiring: • Explicit dependencies in property and constructor-arg settings always override autowiring. You cannot autowire simple properties such as primitives, Strings, and Classes (and arrays of such simple properties). This limitation is by-design. • Autowiring is less exact than explicit wiring. Although, as noted in the earlier table, Spring is careful to avoid guessing in case of ambiguity that might have unexpected results. The relationships between your Spring-managed objects are no longer documented explicitly. • Wiring information may not be available to tools that may generate documentation from a Spring container. • Multiple bean definitions within the container may match the type specified by the setter method or constructor argument to be autowired. For arrays, collections, or Map instances, this is not necessarily a problem. However, for dependencies that expect a single value, this ambiguity is not arbitrarily resolved. If no unique bean definition is available, an exception is thrown. In the latter scenario, you have several options: • Abandon autowiring in favor of explicit wiring. • Avoid autowiring for a bean definition by setting its autowire-candidate attributes to false, as described in the next section. • Designate a single bean definition as the primary candidate by setting the primary attribute of its element to true. • Implement the more fine-grained control available with annotation-based configuration, as described in Annotation-based Container Configuration. Excluding a Bean from Autowiring On a per-bean basis, you can exclude a bean from autowiring. In Spring’s XML format, set the autowire-candidate attribute of the element to false. The container makes that specific bean definition unavailable to the autowiring infrastructure (including annotation style configurations such as @Autowired). The autowire-candidate attribute is designed to only affect type-based autowiring. It does not affect explicit references by name, which get resolved even if the  specified bean is not marked as an autowire candidate. As a consequence, autowiring by name nevertheless injects a bean if the name matches. You can also limit autowire candidates based on pattern-matching against bean names. The top- level element accepts one or more patterns within its default-autowire-candidates attribute. For example, to limit autowire candidate status to any bean whose name ends with Repository, provide a value of *Repository. To provide multiple patterns, define them in a comma- separated list. An explicit value of true or false for a bean definition’s autowire-candidate attribute always takes precedence. For such beans, the pattern matching rules do not apply. These techniques are useful for beans that you never want to be injected into other beans by autowiring. It does not mean that an excluded bean cannot itself be configured by using autowiring. Rather, the bean itself is not a candidate for autowiring other beans. Method Injection In most application scenarios, most beans in the container are singletons. When a singleton bean needs to collaborate with another singleton bean or a non-singleton bean needs to collaborate with another non-singleton bean, you typically handle the dependency by defining one bean as a property of the other. A problem arises when the bean lifecycles are different. Suppose singleton bean A needs to use non-singleton (prototype) bean B, perhaps on each method invocation on A. The container creates the singleton bean A only once, and thus only gets one opportunity to set the properties. The container cannot provide bean A with a new instance of bean B every time one is needed. A solution is to forego some inversion of control. You can make bean A aware of the container by implementing the ApplicationContextAware interface, and by making a getBean("B") call to the container ask for (a typically new) bean B instance every time bean A needs it. The following example shows this approach: Java // a class that uses a stateful Command-style class to perform some processing package fiona.apple; // Spring-API imports import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; public class CommandManager implements ApplicationContextAware {   private ApplicationContext applicationContext;   public Object process(Map commandState) {   // grab a new instance of the appropriate Command   Command command = createCommand();   // set the state on the (hopefully brand new) Command instance   command.setState(commandState);   return command.execute();   }   protected Command createCommand() {   // notice the Spring API dependency!   return this.applicationContext.getBean("command", Command.class);   }   public void setApplicationContext(   ApplicationContext applicationContext) throws BeansException {   this.applicationContext = applicationContext;   } } Kotlin // a class that uses a stateful Command-style class to perform some processing package fiona.apple // Spring-API imports import org.springframework.context.ApplicationContext import org.springframework.context.ApplicationContextAware class CommandManager : ApplicationContextAware {   private lateinit var applicationContext: ApplicationContext   fun process(commandState: Map<*, *>): Any {   // grab a new instance of the appropriate Command   val command = createCommand()   // set the state on the (hopefully brand new) Command instance   command.state = commandState   return command.execute()   }   // notice the Spring API dependency!   protected fun createCommand() =   applicationContext.getBean("command", Command::class.java)   override fun setApplicationContext(applicationContext: ApplicationContext) {   this.applicationContext = applicationContext   } } The preceding is not desirable, because the business code is aware of and coupled to the Spring Framework. Method Injection, a somewhat advanced feature of the Spring IoC container, lets you handle this use case cleanly. You can read more about the motivation for Method Injection in this blog entry. Lookup Method Injection Lookup method injection is the ability of the container to override methods on container-managed beans and return the lookup result for another named bean in the container. The lookup typically involves a prototype bean, as in the scenario described in the preceding section. The Spring Framework implements this method injection by using bytecode generation from the CGLIB library to dynamically generate a subclass that overrides the method. • For this dynamic subclassing to work, the class that the Spring bean container subclasses cannot be final, and the method to be overridden cannot be final, either. • Unit-testing a class that has an abstract method requires you to subclass the class yourself and to supply a stub implementation of the abstract method.  • Concrete methods are also necessary for component scanning, which requires concrete classes to pick up. • A further key limitation is that lookup methods do not work with factory methods and in particular not with @Bean methods in configuration classes, since, in that case, the container is not in charge of creating the instance and therefore cannot create a runtime-generated subclass on the fly. In the case of the CommandManager class in the previous code snippet, the Spring container dynamically overrides the implementation of the createCommand() method. The CommandManager class does not have any Spring dependencies, as the reworked example shows: Java package fiona.apple; // no more Spring imports! public abstract class CommandManager {   public Object process(Object commandState) {   // grab a new instance of the appropriate Command interface   Command command = createCommand();   // set the state on the (hopefully brand new) Command instance   command.setState(commandState);   return command.execute();   }   // okay... but where is the implementation of this method?   protected abstract Command createCommand(); } Kotlin package fiona.apple // no more Spring imports! abstract class CommandManager {   fun process(commandState: Any): Any {   // grab a new instance of the appropriate Command interface   val command = createCommand()   // set the state on the (hopefully brand new) Command instance   command.state = commandState   return command.execute()   }   // okay... but where is the implementation of this method?   protected abstract fun createCommand(): Command } In the client class that contains the method to be injected (the CommandManager in this case), the method to be injected requires a signature of the following form: [abstract] theMethodName(no-arguments); If the method is abstract, the dynamically-generated subclass implements the method. Otherwise, the dynamically-generated subclass overrides the concrete method defined in the original class. Consider the following example:     The bean identified as commandManager calls its own createCommand() method whenever it needs a new instance of the myCommand bean. You must be careful to deploy the myCommand bean as a prototype if that is actually what is needed. If it is a singleton, the same instance of the myCommand bean is returned each time. Alternatively, within the annotation-based component model, you can declare a lookup method through the @Lookup annotation, as the following example shows: Java public abstract class CommandManager {   public Object process(Object commandState) {   Command command = createCommand();   command.setState(commandState);   return command.execute();   }   @Lookup("myCommand")   protected abstract Command createCommand(); } Kotlin abstract class CommandManager {   fun process(commandState: Any): Any {   val command = createCommand()   command.state = commandState   return command.execute()   }   @Lookup("myCommand")   protected abstract fun createCommand(): Command } Or, more idiomatically, you can rely on the target bean getting resolved against the declared return type of the lookup method: Java public abstract class CommandManager {   public Object process(Object commandState) {   Command command = createCommand();   command.setState(commandState);   return command.execute();   }   @Lookup   protected abstract Command createCommand(); } Kotlin abstract class CommandManager {   fun process(commandState: Any): Any {   val command = createCommand()   command.state = commandState   return command.execute()   }   @Lookup   protected abstract fun createCommand(): Command } Note that you should typically declare such annotated lookup methods with a concrete stub implementation, in order for them to be compatible with Spring’s component scanning rules where abstract classes get ignored by default. This limitation does not apply to explicitly registered or explicitly imported bean classes. Another way of accessing differently scoped target beans is an ObjectFactory/ Provider injection point. See Scoped Beans as Dependencies.  You may also find the ServiceLocatorFactoryBean (in the org.springframework.beans.factory.config package) to be useful. Arbitrary Method Replacement A less useful form of method injection than lookup method injection is the ability to replace arbitrary methods in a managed bean with another method implementation. You can safely skip the rest of this section until you actually need this functionality. With XML-based configuration metadata, you can use the replaced-method element to replace an existing method implementation with another, for a deployed bean. Consider the following class, which has a method called computeValue that we want to override: Java public class MyValueCalculator {   public String computeValue(String input) {   // some real code...   }   // some other methods... } Kotlin class MyValueCalculator {   fun computeValue(input: String): String {   // some real code...   }   // some other methods... } A class that implements the org.springframework.beans.factory.support.MethodReplacer interface provides the new method definition, as the following example shows: Java /**  * meant to be used to override the existing computeValue(String)  * implementation in MyValueCalculator  */ public class ReplacementComputeValue implements MethodReplacer {   public Object reimplement(Object o, Method m, Object[] args) throws Throwable {   // get the input value, work with it, and return a computed result   String input = (String) args[0];   ...   return ...;   } } Kotlin /**  * meant to be used to override the existing computeValue(String)  * implementation in MyValueCalculator  */ class ReplacementComputeValue : MethodReplacer {   override fun reimplement(obj: Any, method: Method, args: Array): Any {   // get the input value, work with it, and return a computed result   val input = args[0] as String;   ...   return ...;   } } The bean definition to deploy the original class and specify the method override would resemble the following example:       String   You can use one or more elements within the element to indicate the method signature of the method being overridden. The signature for the arguments is necessary only if the method is overloaded and multiple variants exist within the class. For convenience, the type string for an argument may be a substring of the fully qualified type name. For example, the following all match java.lang.String: java.lang.String String Str Because the number of arguments is often enough to distinguish between each possible choice, this shortcut can save a lot of typing, by letting you type only the shortest string that matches an argument type. 2.1.5. Bean Scopes When you create a bean definition, you create a recipe for creating actual instances of the class defined by that bean definition. The idea that a bean definition is a recipe is important, because it means that, as with a class, you can create many object instances from a single recipe. You can control not only the various dependencies and configuration values that are to be plugged into an object that is created from a particular bean definition but also control the scope of the objects created from a particular bean definition. This approach is powerful and flexible, because you can choose the scope of the objects you create through configuration instead of having to bake in the scope of an object at the Java class level. Beans can be defined to be deployed in one of a number of scopes. The Spring Framework supports six scopes, four of which are available only if you use a web-aware ApplicationContext. You can also create a custom scope. The following table describes the supported scopes: Table 3. Bean scopes Scope Description singleton (Default) Scopes a single bean definition to a single object instance for each Spring IoC container. prototype Scopes a single bean definition to any number of object instances. Scope Description request Scopes a single bean definition to the lifecycle of a single HTTP request. That is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext. session Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext. application Scopes a single bean definition to the lifecycle of a ServletContext. Only valid in the context of a web-aware Spring ApplicationContext. websocket Scopes a single bean definition to the lifecycle of a WebSocket. Only valid in the context of a web-aware Spring ApplicationContext. As of Spring 3.0, a thread scope is available but is not registered by default. For  more information, see the documentation for SimpleThreadScope. For instructions on how to register this or any other custom scope, see Using a Custom Scope. The Singleton Scope Only one shared instance of a singleton bean is managed, and all requests for beans with an ID or IDs that match that bean definition result in that one specific bean instance being returned by the Spring container. To put it another way, when you define a bean definition and it is scoped as a singleton, the Spring IoC container creates exactly one instance of the object defined by that bean definition. This single instance is stored in a cache of such singleton beans, and all subsequent requests and references for that named bean return the cached object. The following image shows how the singleton scope works: Spring’s concept of a singleton bean differs from the singleton pattern as defined in the Gang of Four (GoF) patterns book. The GoF singleton hard-codes the scope of an object such that one and only one instance of a particular class is created per ClassLoader. The scope of the Spring singleton is best described as being per-container and per-bean. This means that, if you define one bean for a particular class in a single Spring container, the Spring container creates one and only one instance of the class defined by that bean definition. The singleton scope is the default scope in Spring. To define a bean as a singleton in XML, you can define a bean as shown in the following example: The Prototype Scope The non-singleton prototype scope of bean deployment results in the creation of a new bean instance every time a request for that specific bean is made. That is, the bean is injected into another bean or you request it through a getBean() method call on the container. As a rule, you should use the prototype scope for all stateful beans and the singleton scope for stateless beans. The following diagram illustrates the Spring prototype scope: (A data access object (DAO) is not typically configured as a prototype, because a typical DAO does not hold any conversational state. It was easier for us to reuse the core of the singleton diagram.) The following example defines a bean as a prototype in XML: In contrast to the other scopes, Spring does not manage the complete lifecycle of a prototype bean. The container instantiates, configures, and otherwise assembles a prototype object and hands it to the client, with no further record of that prototype instance. Thus, although initialization lifecycle callback methods are called on all objects regardless of scope, in the case of prototypes, configured destruction lifecycle callbacks are not called. The client code must clean up prototype-scoped objects and release expensive resources that the prototype beans hold. To get the Spring container to release resources held by prototype-scoped beans, try using a custom bean post-processor, which holds a reference to beans that need to be cleaned up. In some respects, the Spring container’s role in regard to a prototype-scoped bean is a replacement for the Java new operator. All lifecycle management past that point must be handled by the client. (For details on the lifecycle of a bean in the Spring container, see Lifecycle Callbacks.) Singleton Beans with Prototype-bean Dependencies When you use singleton-scoped beans with dependencies on prototype beans, be aware that dependencies are resolved at instantiation time. Thus, if you dependency-inject a prototype-scoped bean into a singleton-scoped bean, a new prototype bean is instantiated and then dependency- injected into the singleton bean. The prototype instance is the sole instance that is ever supplied to the singleton-scoped bean. However, suppose you want the singleton-scoped bean to acquire a new instance of the prototype- scoped bean repeatedly at runtime. You cannot dependency-inject a prototype-scoped bean into your singleton bean, because that injection occurs only once, when the Spring container instantiates the singleton bean and resolves and injects its dependencies. If you need a new instance of a prototype bean at runtime more than once, see Method Injection. Request, Session, Application, and WebSocket Scopes The request, session, application, and websocket scopes are available only if you use a web-aware Spring ApplicationContext implementation (such as XmlWebApplicationContext). If you use these scopes with regular Spring IoC containers, such as the ClassPathXmlApplicationContext, an IllegalStateException that complains about an unknown bean scope is thrown. Initial Web Configuration To support the scoping of beans at the request, session, application, and websocket levels (web- scoped beans), some minor initial configuration is required before you define your beans. (This initial setup is not required for the standard scopes: singleton and prototype.) How you accomplish this initial setup depends on your particular Servlet environment. If you access scoped beans within Spring Web MVC, in effect, within a request that is processed by the Spring DispatcherServlet, no special setup is necessary. DispatcherServlet already exposes all relevant state. If you use a Servlet web container, with requests processed outside of Spring’s DispatcherServlet (for example, when using JSF or Struts), you need to register the org.springframework.web.context.request.RequestContextListener ServletRequestListener. This can be done programmatically by using the WebApplicationInitializer interface. Alternatively, add the following declaration to your web application’s web.xml file:   ...       org.springframework.web.context.request.RequestContextListener       ... Alternatively, if there are issues with your listener setup, consider using Spring’s RequestContextFilter. The filter mapping depends on the surrounding web application configuration, so you have to change it as appropriate. The following listing shows the filter part of a web application:   ...     requestContextFilter   org.springframework.web.filter.RequestContextFilter       requestContextFilter   /*     ... DispatcherServlet, RequestContextListener, and RequestContextFilter all do exactly the same thing, namely bind the HTTP request object to the Thread that is servicing that request. This makes beans that are request- and session-scoped available further down the call chain. Request scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the LoginAction bean by using the loginAction bean definition for each and every HTTP request. That is, the loginAction bean is scoped at the HTTP request level. You can change the internal state of the instance that is created as much as you want, because other instances created from the same loginAction bean definition do not see these changes in state. They are particular to an individual request. When the request completes processing, the bean that is scoped to the request is discarded. When using annotation-driven components or Java configuration, the @RequestScope annotation can be used to assign a component to the request scope. The following example shows how to do so: Java @RequestScope @Component public class LoginAction {   // ... } Kotlin @RequestScope @Component class LoginAction {   // ... } Session Scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the UserPreferences bean by using the userPreferences bean definition for the lifetime of a single HTTP Session. In other words, the userPreferences bean is effectively scoped at the HTTP Session level. As with request-scoped beans, you can change the internal state of the instance that is created as much as you want, knowing that other HTTP Session instances that are also using instances created from the same userPreferences bean definition do not see these changes in state, because they are particular to an individual HTTP Session. When the HTTP Session is eventually discarded, the bean that is scoped to that particular HTTP Session is also discarded. When using annotation-driven components or Java configuration, you can use the @SessionScope annotation to assign a component to the session scope. Java @SessionScope @Component public class UserPreferences {   // ... } Kotlin @SessionScope @Component class UserPreferences {   // ... } Application Scope Consider the following XML configuration for a bean definition: The Spring container creates a new instance of the AppPreferences bean by using the appPreferences bean definition once for the entire web application. That is, the appPreferences bean is scoped at the ServletContext level and stored as a regular ServletContext attribute. This is somewhat similar to a Spring singleton bean but differs in two important ways: It is a singleton per ServletContext, not per Spring ApplicationContext (for which there may be several in any given web application), and it is actually exposed and therefore visible as a ServletContext attribute. When using annotation-driven components or Java configuration, you can use the @ApplicationScope annotation to assign a component to the application scope. The following example shows how to do so: Java @ApplicationScope @Component public class AppPreferences {   // ... } Kotlin @ApplicationScope @Component class AppPreferences {   // ... } WebSocket Scope WebSocket scope is associated with the lifecycle of a WebSocket session and applies to STOMP over WebSocket applications, see WebSocket scope for more details. Scoped Beans as Dependencies The Spring IoC container manages not only the instantiation of your objects (beans), but also the wiring up of collaborators (or dependencies). If you want to inject (for example) an HTTP request- scoped bean into another bean of a longer-lived scope, you may choose to inject an AOP proxy in place of the scoped bean. That is, you need to inject a proxy object that exposes the same public interface as the scoped object but that can also retrieve the real target object from the relevant scope (such as an HTTP request) and delegate method calls onto the real object. You may also use between beans that are scoped as singleton, with the reference then going through an intermediate proxy that is serializable and therefore able to re-obtain the target singleton bean on deserialization. When declaring against a bean of scope prototype, every method call on the shared proxy leads to the creation of a new target instance to which the call is then being forwarded. Also, scoped proxies are not the only way to access beans from shorter scopes in a lifecycle-safe fashion. You may also declare your injection point (that is, the  constructor or setter argument or autowired field) as ObjectFactory, allowing for a getObject() call to retrieve the current instance on demand every time it is needed — without holding on to the instance or storing it separately. As an extended variant, you may declare ObjectProvider which delivers several additional access variants, including getIfAvailable and getIfUnique. The JSR-330 variant of this is called Provider and is used with a Provider declaration and a corresponding get() call for every retrieval attempt. See here for more details on JSR-330 overall. The configuration in the following example is only one line, but it is important to understand the “why” as well as the “how” behind it:         ①             ① The line that defines the proxy. To create such a proxy, you insert a child element into a scoped bean definition (see Choosing the Type of Proxy to Create and XML Schema-based configuration). Why do definitions of beans scoped at the request, session and custom-scope levels require the element? Consider the following singleton bean definition and contrast it with what you need to define for the aforementioned scopes (note that the following userPreferences bean definition as it stands is incomplete):   In the preceding example, the singleton bean (userManager) is injected with a reference to the HTTP Session-scoped bean (userPreferences). The salient point here is that the userManager bean is a singleton: it is instantiated exactly once per container, and its dependencies (in this case only one, the userPreferences bean) are also injected only once. This means that the userManager bean operates only on the exact same userPreferences object (that is, the one with which it was originally injected). This is not the behavior you want when injecting a shorter-lived scoped bean into a longer-lived scoped bean (for example, injecting an HTTP Session-scoped collaborating bean as a dependency into singleton bean). Rather, you need a single userManager object, and, for the lifetime of an HTTP Session, you need a userPreferences object that is specific to the HTTP Session. Thus, the container creates an object that exposes the exact same public interface as the UserPreferences class (ideally an object that is a UserPreferences instance), which can fetch the real UserPreferences object from the scoping mechanism (HTTP request, Session, and so forth). The container injects this proxy object into the userManager bean, which is unaware that this UserPreferences reference is a proxy. In this example, when a UserManager instance invokes a method on the dependency-injected UserPreferences object, it is actually invoking a method on the proxy. The proxy then fetches the real UserPreferences object from (in this case) the HTTP Session and delegates the method invocation onto the retrieved real UserPreferences object. Thus, you need the following (correct and complete) configuration when injecting request- and session-scoped beans into collaborating objects, as the following example shows:     Choosing the Type of Proxy to Create By default, when the Spring container creates a proxy for a bean that is marked up with the element, a CGLIB-based class proxy is created. CGLIB proxies intercept only public method calls! Do not call non-public methods  on such a proxy. They are not delegated to the actual scoped target object. Alternatively, you can configure the Spring container to create standard JDK interface-based proxies for such scoped beans, by specifying false for the value of the proxy-target-class attribute of the element. Using JDK interface-based proxies means that you do not need additional libraries in your application classpath to affect such proxying. However, it also means that the class of the scoped bean must implement at least one interface and that all collaborators into which the scoped bean is injected must reference the bean through one of its interfaces. The following example shows a proxy based on an interface:     For more detailed information about choosing class-based or interface-based proxying, see Proxying Mechanisms. Custom Scopes The bean scoping mechanism is extensible. You can define your own scopes or even redefine existing scopes, although the latter is considered bad practice and you cannot override the built-in singleton and prototype scopes. Creating a Custom Scope To integrate your custom scopes into the Spring container, you need to implement the org.springframework.beans.factory.config.Scope interface, which is described in this section. For an idea of how to implement your own scopes, see the Scope implementations that are supplied with the Spring Framework itself and the Scope javadoc, which explains the methods you need to implement in more detail. The Scope interface has four methods to get objects from the scope, remove them from the scope, and let them be destroyed. The session scope implementation, for example, returns the session-scoped bean (if it does not exist, the method returns a new instance of the bean, after having bound it to the session for future reference). The following method returns the object from the underlying scope: Java Object get(String name, ObjectFactory objectFactory) Kotlin fun get(name: String, objectFactory: ObjectFactory<*>): Any The session scope implementation, for example, removes the session-scoped bean from the underlying session. The object should be returned, but you can return null if the object with the specified name is not found. The following method removes the object from the underlying scope: Java Object remove(String name) Kotlin fun remove(name: String): Any The following method registers a callback that the scope should invoke when it is destroyed or when the specified object in the scope is destroyed: Java void registerDestructionCallback(String name, Runnable destructionCallback) Kotlin fun registerDestructionCallback(name: String, destructionCallback: Runnable) See the javadoc or a Spring scope implementation for more information on destruction callbacks. The following method obtains the conversation identifier for the underlying scope: Java String getConversationId() Kotlin fun getConversationId(): String This identifier is different for each scope. For a session scoped implementation, this identifier can be the session identifier. Using a Custom Scope After you write and test one or more custom Scope implementations, you need to make the Spring container aware of your new scopes. The following method is the central method to register a new Scope with the Spring container: Java void registerScope(String scopeName, Scope scope); Kotlin fun registerScope(scopeName: String, scope: Scope) This method is declared on the ConfigurableBeanFactory interface, which is available through the BeanFactory property on most of the concrete ApplicationContext implementations that ship with Spring. The first argument to the registerScope(..) method is the unique name associated with a scope. Examples of such names in the Spring container itself are singleton and prototype. The second argument to the registerScope(..) method is an actual instance of the custom Scope implementation that you wish to register and use. Suppose that you write your custom Scope implementation, and then register it as shown in the next example. The next example uses SimpleThreadScope, which is included with Spring but is not  registered by default. The instructions would be the same for your own custom Scope implementations. Java Scope threadScope = new SimpleThreadScope(); beanFactory.registerScope("thread", threadScope); Kotlin val threadScope = SimpleThreadScope() beanFactory.registerScope("thread", threadScope) You can then create bean definitions that adhere to the scoping rules of your custom Scope, as follows: With a custom Scope implementation, you are not limited to programmatic registration of the scope. You can also do the Scope registration declaratively, by using the CustomScopeConfigurer class, as the following example shows:                                 When you place within a declaration for a FactoryBean  implementation, it is the factory bean itself that is scoped, not the object returned from getObject(). 2.1.6. Customizing the Nature of a Bean The Spring Framework provides a number of interfaces you can use to customize the nature of a bean. This section groups them as follows: • Lifecycle Callbacks • ApplicationContextAware and BeanNameAware • Other Aware Interfaces Lifecycle Callbacks To interact with the container’s management of the bean lifecycle, you can implement the Spring InitializingBean and DisposableBean interfaces. The container calls afterPropertiesSet() for the former and destroy() for the latter to let the bean perform certain actions upon initialization and destruction of your beans. The JSR-250 @PostConstruct and @PreDestroy annotations are generally considered best practice for receiving lifecycle callbacks in a modern Spring application. Using these annotations means that your beans are not coupled to Spring-specific  interfaces. For details, see Using @PostConstruct and @PreDestroy. If you do not want to use the JSR-250 annotations but you still want to remove coupling, consider init-method and destroy-method bean definition metadata. Internally, the Spring Framework uses BeanPostProcessor implementations to process any callback interfaces it can find and call the appropriate methods. If you need custom features or other lifecycle behavior Spring does not by default offer, you can implement a BeanPostProcessor yourself. For more information, see Container Extension Points. In addition to the initialization and destruction callbacks, Spring-managed objects may also implement the Lifecycle interface so that those objects can participate in the startup and shutdown process, as driven by the container’s own lifecycle. The lifecycle callback interfaces are described in this section. Initialization Callbacks The org.springframework.beans.factory.InitializingBean interface lets a bean perform initialization work after the container has set all necessary properties on the bean. The InitializingBean interface specifies a single method: void afterPropertiesSet() throws Exception; We recommend that you do not use the InitializingBean interface, because it unnecessarily couples the code to Spring. Alternatively, we suggest using the @PostConstruct annotation or specifying a POJO initialization method. In the case of XML-based configuration metadata, you can use the init- method attribute to specify the name of the method that has a void no-argument signature. With Java configuration, you can use the initMethod attribute of @Bean. See Receiving Lifecycle Callbacks. Consider the following example: Java public class ExampleBean {   public void init() {   // do some initialization work   } } Kotlin class ExampleBean {   fun init() {   // do some initialization work   } } The preceding example has almost exactly the same effect as the following example (which consists of two listings): Java public class AnotherExampleBean implements InitializingBean {   @Override   public void afterPropertiesSet() {   // do some initialization work   } } Kotlin class AnotherExampleBean : InitializingBean {   override fun afterPropertiesSet() {   // do some initialization work   } } However, the first of the two preceding examples does not couple the code to Spring. Destruction Callbacks Implementing the org.springframework.beans.factory.DisposableBean interface lets a bean get a callback when the container that contains it is destroyed. The DisposableBean interface specifies a single method: void destroy() throws Exception; We recommend that you do not use the DisposableBean callback interface, because it unnecessarily couples the code to Spring. Alternatively, we suggest using the @PreDestroy annotation or specifying a generic method that is supported by bean definitions. With XML-based configuration metadata, you can use the destroy-method attribute on the . With Java configuration, you can use the destroyMethod attribute of @Bean. See Receiving Lifecycle Callbacks. Consider the following definition: Java public class ExampleBean {   public void cleanup() {   // do some destruction work (like releasing pooled connections)   } } Kotlin class ExampleBean {   fun cleanup() {   // do some destruction work (like releasing pooled connections)   } } The preceding definition has almost exactly the same effect as the following definition: Java public class AnotherExampleBean implements DisposableBean {   @Override   public void destroy() {   // do some destruction work (like releasing pooled connections)   } } Kotlin class AnotherExampleBean : DisposableBean {   override fun destroy() {   // do some destruction work (like releasing pooled connections)   } } However, the first of the two preceding definitions does not couple the code to Spring. You can assign the destroy-method attribute of a element a special (inferred) value, which instructs Spring to automatically detect a public close or shutdown method on the specific bean class. (Any class that implements java.lang.AutoCloseable or java.io.Closeable would therefore match.) You can  also set this special (inferred) value on the default-destroy-method attribute of a element to apply this behavior to an entire set of beans (see Default Initialization and Destroy Methods). Note that this is the default behavior with Java configuration. Default Initialization and Destroy Methods When you write initialization and destroy method callbacks that do not use the Spring-specific InitializingBean and DisposableBean callback interfaces, you typically write methods with names such as init(), initialize(), dispose(), and so on. Ideally, the names of such lifecycle callback methods are standardized across a project so that all developers use the same method names and ensure consistency. You can configure the Spring container to “look” for named initialization and destroy callback method names on every bean. This means that you, as an application developer, can write your application classes and use an initialization callback called init(), without having to configure an init-method="init" attribute with each bean definition. The Spring IoC container calls that method when the bean is created (and in accordance with the standard lifecycle callback contract described previously). This feature also enforces a consistent naming convention for initialization and destroy method callbacks. Suppose that your initialization callback methods are named init() and your destroy callback methods are named destroy(). Your class then resembles the class in the following example: Java public class DefaultBlogService implements BlogService {   private BlogDao blogDao;   public void setBlogDao(BlogDao blogDao) {   this.blogDao = blogDao;   }   // this is (unsurprisingly) the initialization callback method   public void init() {   if (this.blogDao == null) {   throw new IllegalStateException("The [blogDao] property must be set.");   }   } } Kotlin class DefaultBlogService : BlogService {   private var blogDao: BlogDao? = null   // this is (unsurprisingly) the initialization callback method   fun init() {   if (blogDao == null) {   throw IllegalStateException("The [blogDao] property must be set.")   }   } } You could then use that class in a bean resembling the following:       The presence of the default-init-method attribute on the top-level element attribute causes the Spring IoC container to recognize a method called init on the bean class as the initialization method callback. When a bean is created and assembled, if the bean class has such a method, it is invoked at the appropriate time. You can configure destroy method callbacks similarly (in XML, that is) by using the default- destroy-method attribute on the top-level element. Where existing bean classes already have callback methods that are named at variance with the convention, you can override the default by specifying (in XML, that is) the method name by using the init-method and destroy-method attributes of the itself. The Spring container guarantees that a configured initialization callback is called immediately after a bean is supplied with all dependencies. Thus, the initialization callback is called on the raw bean reference, which means that AOP interceptors and so forth are not yet applied to the bean. A target bean is fully created first and then an AOP proxy (for example) with its interceptor chain is applied. If the target bean and the proxy are defined separately, your code can even interact with the raw target bean, bypassing the proxy. Hence, it would be inconsistent to apply the interceptors to the init method, because doing so would couple the lifecycle of the target bean to its proxy or interceptors and leave strange semantics when your code interacts directly with the raw target bean. ================================================ FILE: spring-ai-docs/pom.xml ================================================ 4.0.0

[[Advisors-Recursive]] = Recursive Advisors == What is a Recursive Advisor? image:advisors-recursive.png[Advisors Recursive, width=230, float="right", align="center", alt="Advisors Recursive"] Recursive advisors are a special type of advisor that can loop through the downstream advisor chain multiple times. This pattern is useful when you need to repeatedly call the LLM until a certain condition is met, such as: * Executing tool calls in a loop until no more tools need to be called * Validating structured output and retrying if validation fails * Implementing Evaluation logic with modifications to the request * Implementing retry logic with modifications to the request The `CallAdvisorChain.copy(CallAdvisor after)` method is the key utility that enables recursive advisor patterns. It creates a new advisor chain that contains only the advisors that come after the specified advisor in the original chain and allows the recursive advisor to call this sub-chain as needed. This approach ensures that: * The recursive advisor can loop through the remaining advisors in the chain * Other advisors in the chain can observe and intercept each iteration * The advisor chain maintains proper ordering and observability * The recursive advisor doesn't re-execute advisors that came before it == Built-in Recursive Advisors Spring AI provides two built-in recursive advisors that demonstrate this pattern: === ToolCallAdvisor The `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. Key features: * Disables the model's internal tool execution by setting `setInternalToolExecutionEnabled(false)` * Loops through the advisor chain until no more tool calls are present * 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 * Uses `callAdvisorChain.copy(this)` to create a sub-chain for recursive calls * Includes null safety checks to handle cases where the chat response might be null * Supports configurable conversation history management via `conversationHistoryEnabled` Example usage: [source,java] ---- var toolCallAdvisor = ToolCallAdvisor.builder() .toolCallingManager(toolCallingManager) .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 300) .build(); var chatClient = ChatClient.builder(chatModel) .defaultAdvisors(toolCallAdvisor) .build(); ---- ==== Conversation History Management The `ToolCallAdvisor` includes a `conversationHistoryEnabled` configuration option that controls how conversation history is managed during tool calling iterations. By 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). Use 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: * You have a Chat Memory Advisor registered next in the chain that already manages conversation history * You want to reduce token usage by not duplicating history management * You're integrating with external conversation memory systems Example with conversation history disabled: [source,java] ---- var toolCallAdvisor = ToolCallAdvisor.builder() .toolCallingManager(toolCallingManager) .disableInternalConversationHistory() // Disable internal history - let ChatMemory handle it .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 300) .build(); var chatMemoryAdvisor = MessageChatMemoryAdvisor.builder(chatMemory) .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 200) // Positioned before ToolCallAdvisor .build(); var chatClient = ChatClient.builder(chatModel) .defaultAdvisors(chatMemoryAdvisor, toolCallAdvisor) .build(); ---- ==== Return Direct Functionality The "return direct" feature allows tools to bypass the LLM and return their results directly to the client application. This is useful when: * The tool's output is the final answer and doesn't need LLM processing * You want to reduce latency by avoiding an additional LLM call * The tool result should be returned as-is without interpretation When a tool execution has `returnDirect=true`, the `ToolCallAdvisor` will: 1. Execute the tool call as normal 2. Detect the `returnDirect` flag in the `ToolExecutionResult` 3. Break out of the tool calling loop 4. Return the tool execution result directly to the client application as a `ChatResponse` with the tool's output as the generation content === StructuredOutputValidationAdvisor The `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. Key features: * Automatically generates a JSON schema from the expected output type * Validates the LLM response against the schema * Retries the call if validation fails, up to a configurable number of attempts * Augments the prompt with validation error messages on retry attempts to help the LLM correct its output * Uses `callAdvisorChain.copy(this)` to create a sub-chain for recursive calls * Optionally supports a custom `JsonMapper` for JSON processing Example usage: [source,java] ---- var validationAdvisor = StructuredOutputValidationAdvisor.builder() .outputType(MyResponseType.class) .maxRepeatAttempts(3) .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 1000) .build(); var chatClient = ChatClient.builder(chatModel) .defaultAdvisors(validationAdvisor) .build(); ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/advisors.adoc ================================================ [[Advisors]] = Advisors API The Spring AI Advisors API provides a flexible and powerful way to intercept, modify, and enhance AI-driven interactions in your Spring applications. By leveraging the Advisors API, developers can create more sophisticated, reusable, and maintainable AI components. The 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. You can configure existing advisors using the xref:api/chatclient.adoc#_advisor_configuration_in_chatclient[ChatClient API] as shown in the following example: [source,java] ---- ChatMemory chatMemory = ... // Initialize your chat memory store VectorStore vectorStore = ... // Initialize your vector store var chatClient = ChatClient.builder(chatModel) .defaultAdvisors( MessageChatMemoryAdvisor.builder(chatMemory).build(), // chat-memory advisor QuestionAnswerAdvisor.builder(vectorStore).build() // RAG advisor ) .build(); var conversationId = "678"; String response = this.chatClient.prompt() // Set advisor parameters at runtime .advisors(advisor -> advisor.param(ChatMemory.CONVERSATION_ID, conversationId)) .user(userText) .call() .content(); ---- It is recommend to register the advisors at build time using builder's `defaultAdvisors()` method. Advisors also participate in the Observability stack, so you can view metrics and traces related to their execution. - xref:ROOT:api/retrieval-augmented-generation.adoc#_questionansweradvisor[Learn about Question Answer Advisor] - xref:ROOT:api/chat-memory.adoc#_memory_in_chat_client[Learn about Chat Memory Advisor] == Core Components The API consists of `CallAdvisor` and `CallAdvisorChain` for non-streaming scenarios, and `StreamAdvisor` and `StreamAdvisorChain` for streaming scenarios. It 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. image::advisors-api-classes.jpg[Advisors API Classes, width=600, align="center"] The `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. In addition the `getOrder()` method determines advisor order in the chain, while `getName()` provides a unique advisor name. The Advisor Chain, created by the Spring AI framework, allows sequential invocation of multiple advisors ordered by their `getOrder()` values. The lower values are executed first. The last advisor, added automatically, sends the request to the LLM. Following flow diagram illustrates the interaction between the advisor chain and the Chat Model: image::advisors-flow.jpg[Advisors API Flow, width=400, align="center"] . The Spring AI framework creates an `ChatClientRequest` from user's `Prompt` along with an empty advisor `context` object. . 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. . The final advisor, provided by the framework, sends the request to the `Chat Model`. . The Chat Model's response is then passed back through the advisor chain and converted into `ChatClientResponse`. Later includes the shared advisor `context` instance. . Each advisor can process or modify the response. . The final `ChatClientResponse` is returned to the client by extracting the `ChatCompletion`. === Advisor Order The execution order of advisors in the chain is determined by the `getOrder()` method. Key points to understand: * Advisors with lower order values are executed first. * The advisor chain operates as a stack: ** The first advisor in the chain is the first to process the request. ** It is also the last to process the response. * To control execution order: ** 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). ** 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). * Higher values are interpreted as lower priority. * If multiple advisors have the same order value, their execution order is not guaranteed. [NOTE] ==== The seeming contradiction between order and execution sequence is due to the stack-like nature of the advisor chain: - An advisor with the highest precedence (lowest order value) is added to the top of the stack. - It will be the first to process the request as the stack unwinds. - It will be the last to process the response as the stack rewinds. ==== As a reminder, here are the semantics of the Spring `Ordered` interface: [source,java] ---- public interface Ordered { /** * Constant for the highest precedence value. * @see java.lang.Integer#MIN_VALUE */ int HIGHEST_PRECEDENCE = Integer.MIN_VALUE; /** * Constant for the lowest precedence value. * @see java.lang.Integer#MAX_VALUE */ int LOWEST_PRECEDENCE = Integer.MAX_VALUE; /** * Get the order value of this object. *

Higher values are interpreted as lower priority. As a consequence, * the object with the lowest value has the highest priority (somewhat * analogous to Servlet {@code load-on-startup} values). *

Same order values will result in arbitrary sort positions for the * affected objects. * @return the order value * @see #HIGHEST_PRECEDENCE * @see #LOWEST_PRECEDENCE */ int getOrder(); } ---- [TIP] ==== For use cases that need to be first in the chain on both the input and output sides: 1. Use separate advisors for each side. 2. Configure them with different order values. 3. Use the advisor context to share state between them. ==== == API Overview The 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: ```java public interface Advisor extends Ordered { String getName(); } ``` The two sub-interfaces for synchronous and reactive Advisors are ```java public interface CallAdvisor extends Advisor { ChatClientResponse adviseCall( ChatClientRequest chatClientRequest, CallAdvisorChain callAdvisorChain); } ``` and ```java public interface StreamAdvisor extends Advisor { Flux adviseStream( ChatClientRequest chatClientRequest, StreamAdvisorChain streamAdvisorChain); } ``` To continue the chain of Advice, use `CallAdvisorChain` and `StreamAdvisorChain` in your Advice implementation: The interfaces are ```java public interface CallAdvisorChain extends AdvisorChain { /** * Invokes the next {@link CallAdvisor} in the {@link CallAdvisorChain} with the given * request. */ ChatClientResponse nextCall(ChatClientRequest chatClientRequest); /** * Returns the list of all the {@link CallAdvisor} instances included in this chain at * the time of its creation. */ List getCallAdvisors(); } ``` and ```java public interface StreamAdvisorChain extends AdvisorChain { /** * Invokes the next {@link StreamAdvisor} in the {@link StreamAdvisorChain} with the * given request. */ Flux nextStream(ChatClientRequest chatClientRequest); /** * Returns the list of all the {@link StreamAdvisor} instances included in this chain * at the time of its creation. */ List getStreamAdvisors(); } ``` == Implementing an Advisor To 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. === Examples We will provide few hands-on examples to illustrate how to implement advisors for observing and augmenting use-cases. ==== Logging Advisor We can implement a simple logging advisor that logs the `ChatClientRequest` before and the `ChatClientResponse` after the call to the next advisor in the chain. Note that the advisor only observes the request and response and does not modify them. This implementation support both non-streaming and streaming scenarios. [source,java] ---- public class SimpleLoggerAdvisor implements CallAdvisor, StreamAdvisor { private static final Logger logger = LoggerFactory.getLogger(SimpleLoggerAdvisor.class); @Override public String getName() { // <1> return this.getClass().getSimpleName(); } @Override public int getOrder() { // <2> return 0; } @Override public ChatClientResponse adviseCall(ChatClientRequest chatClientRequest, CallAdvisorChain callAdvisorChain) { logRequest(chatClientRequest); ChatClientResponse chatClientResponse = callAdvisorChain.nextCall(chatClientRequest); logResponse(chatClientResponse); return chatClientResponse; } @Override public Flux adviseStream(ChatClientRequest chatClientRequest, StreamAdvisorChain streamAdvisorChain) { logRequest(chatClientRequest); Flux chatClientResponses = streamAdvisorChain.nextStream(chatClientRequest); return new ChatClientMessageAggregator().aggregateChatClientResponse(chatClientResponses, this::logResponse); // <3> } private void logRequest(ChatClientRequest request) { logger.debug("request: {}", request); } private void logResponse(ChatClientResponse chatClientResponse) { logger.debug("response: {}", chatClientResponse); } } ---- <1> Provides a unique name for the advisor. <2> You can control the order of execution by setting the order value. Lower values execute first. <3> The `MessageAggregator` is a utility class that aggregates the Flux responses into a single ChatClientResponse. This can be useful for logging or other processing that observe the entire response rather than individual items in the stream. Note that you can not alter the response in the `MessageAggregator` as it is a read-only operation. ==== Re-Reading (Re2) Advisor The "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. The Re2 technique requires augmenting the input prompt like this: ---- {Input_Query} Read the question again: {Input_Query} ---- Implementing an advisor that applies the Re2 technique to the user's input query can be done like this: [source,java] ---- public class ReReadingAdvisor implements BaseAdvisor { private static final String DEFAULT_RE2_ADVISE_TEMPLATE = """ {re2_input_query} Read the question again: {re2_input_query} """; private final String re2AdviseTemplate; private int order = 0; public ReReadingAdvisor() { this(DEFAULT_RE2_ADVISE_TEMPLATE); } public ReReadingAdvisor(String re2AdviseTemplate) { this.re2AdviseTemplate = re2AdviseTemplate; } @Override public ChatClientRequest before(ChatClientRequest chatClientRequest, AdvisorChain advisorChain) { // <1> String augmentedUserText = PromptTemplate.builder() .template(this.re2AdviseTemplate) .variables(Map.of("re2_input_query", chatClientRequest.prompt().getUserMessage().getText())) .build() .render(); return chatClientRequest.mutate() .prompt(chatClientRequest.prompt().augmentUserMessage(augmentedUserText)) .build(); } @Override public ChatClientResponse after(ChatClientResponse chatClientResponse, AdvisorChain advisorChain) { return chatClientResponse; } @Override public int getOrder() { // <2> return this.order; } public ReReadingAdvisor withOrder(int order) { this.order = order; return this; } } ---- <1> The `before` method augments the user's input query applying the Re-Reading technique. <2> You can control the order of execution by setting the order value. Lower values execute first. ==== Spring AI Built-in Advisors Spring AI framework provides several built-in advisors to enhance your AI interactions. Here's an overview of the available advisors: ===== Chat Memory Advisors These advisors manage conversation history in a chat memory store: * `MessageChatMemoryAdvisor` + Retrieves 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. * `PromptChatMemoryAdvisor` + Retrieves memory and incorporates it into the prompt's system text. * `VectorStoreChatMemoryAdvisor` + Retrieves 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. ===== Question Answering Advisor * `QuestionAnswerAdvisor` + This advisor uses a vector store to provide question-answering capabilities, implementing the Naive RAG (Retrieval-Augmented Generation) pattern. * `RetrievalAugmentationAdvisor` + 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. ===== Reasoning Advisor * `ReReadingAdvisor` + Implements a re-reading strategy for LLM reasoning, dubbed RE2, to enhance understanding in the input phase. Based on the article: [Re-Reading Improves Reasoning in LLMs](https://arxiv.org/pdf/2309.06275). ===== Content Safety Advisor * `SafeGuardAdvisor` + A simple advisor designed to prevent the model from generating harmful or inappropriate content. === Streaming vs Non-Streaming image::advisors-non-stream-vs-stream.jpg[Advisors Streaming vs Non-Streaming Flow, width=800, align="center"] * Non-streaming advisors work with complete requests and responses. * Streaming advisors handle requests and responses as continuous streams, using reactive programming concepts (e.g., Flux for responses). // TODO - Add a section on how to implement a streaming advisor with blocking and non-blocking code. [source,java] ---- @Override public Flux adviseStream(ChatClientRequest chatClientRequest, StreamAdvisorChain chain) { return Mono.just(chatClientRequest) .publishOn(Schedulers.boundedElastic()) .map(request -> { // This can be executed by blocking and non-blocking Threads. // Advisor before next section }) .flatMapMany(request -> chain.nextStream(request)) .map(response -> { // Advisor after next section }); } ---- === Best Practices . Keep advisors focused on specific tasks for better modularity. . Use the `adviseContext` to share state between advisors when necessary. . Implement both streaming and non-streaming versions of your advisor for maximum flexibility. . Carefully consider the order of advisors in your chain to ensure proper data flow. == Breaking API Changes === Advisor Interfaces * In 1.0 M2, there were separate `RequestAdvisor` and `ResponseAdvisor` interfaces. ** `RequestAdvisor` was invoked before the `ChatModel.call` and `ChatModel.stream` methods. ** `ResponseAdvisor` was called after these methods. * In 1.0 M3, these interfaces have been replaced with: ** `CallAroundAdvisor` ** `StreamAroundAdvisor` * The `StreamResponseMode`, previously part of `ResponseAdvisor`, has been removed. * In 1.0.0 these interfaces have been replaced: ** `CallAroundAdvisor` -> `CallAdvisor`, `StreamAroundAdvisor` -> `StreamAdvisor`, `CallAroundAdvisorChain` -> `CallAdvisorChain` and `StreamAroundAdvisorChain` -> `StreamAdvisorChain`. ** `AdvisedRequest` -> `ChatClientRequest` and `AdivsedResponse` -> `ChatClientResponse`. === Context Map Handling * In 1.0 M2: ** The context map was a separate method argument. ** The map was mutable and passed along the chain. * In 1.0 M3: ** The context map is now part of the `AdvisedRequest` and `AdvisedResponse` records. ** The map is immutable. ** To update the context, use the `updateContext` method, which creates a new unmodifiable map with the updated contents. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/aimetadata.adoc ================================================ [[AiMetadata]] = AI metadata Use 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. Consumption 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. Your 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. To 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. Spring 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. [[AiMetadata-GenerationMetadata]] == `GenerationMetadata` interface The `GenerationMetadata` interface is defined as: .GenerationMetadata interface [source,java] ---- interface GenerationMetadata { default RateLimit getRateLimit() { return RateLimit.NULL; } default Usage getUsage() { return Usage.NULL; } } ---- An 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: .Get access to `GenerationMetadata` from `ChatResponse` [source,java] ---- @Service class MyService { ApplicationObjectType askTheAi(ServiceRequest request) { Prompt prompt = createPrompt(request); ChatResponse response = chatModel.call(prompt); // Process the chat response GenerationMetadata metadata = response.getMetadata(); // Inspect the AI metadata returned in the chat response of the AI providers API Long totalTokensUsedInAiPromptAndResponse = metadata.getUsage().getTotalTokens(); // Act on this information somehow } } ---- You 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. Minimally, you can simply gather these metrics to monitor and report on your consumption. [[AiMetadata-RateLimit]] == RateLimit The `RateLimit` interface provides access to actual information returned by an AI provider on your API usage when making AI requests. .`RateLimit` interface [source,java] ---- interface RateLimit { Long getRequestsLimit(); Long getRequestsRemaining(); Duration getRequestsReset(); Long getTokensLimit(); Long getTokensRemaining(); Duration getTokensReset(); } ---- `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. The methods for `tokensLimit`, `tokensRemaining` and `tokensReset` are similar to the methods for requests, but focus on token limits, balance and resets instead. The `RateLimit` instance can be acquired from the `GenerationMetadata`, like so: .Get access to `RateLimit` from `GenerationMetadata` [source,java] ---- RateLimit rateLimit = generationMetadata.getRateLimit(); Long tokensRemaining = this.rateLimit.getTokensRemaining(); // do something interesting with the RateLimit metadata ---- For 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. Because 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: .Enable API rate limit collection from AI metadata [source,properties] ---- # Spring Boot application.properties spring.ai.openai.metadata.rate-limit-metrics-enabled=true ---- [[AiMetadata-Usage]] == Usage As shown <>, `Usage` data can be obtained from the `GenerationMetadata` object. The `Usage` interface is defined as: .`Usage` interface [source,java] ---- interface Usage { Long getPromptTokens(); Long getGenerationTokens(); default Long getTotalTokens() { return getPromptTokens() + getGenerationTokens(); } } ---- The method names are self-explanatory, but tells you the tokens that the AI required to process the `Prompt` and generate a response. `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. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/audio/speech/elevenlabs-speech.adoc ================================================ = ElevenLabs Text-to-Speech (TTS) == Introduction ElevenLabs provides natural-sounding speech synthesis software using deep learning. Its AI audio models generate realistic, versatile, and contextually-aware speech, voices, and sound effects across 32 languages. The ElevenLabs Text-to-Speech API enables users to bring any book, article, PDF, newsletter, or text to life with ultra-realistic AI narration. == Prerequisites . Create an ElevenLabs account and obtain an API key. You can sign up at the https://elevenlabs.io/sign-up[ElevenLabs signup page]. Your API key can be found on your profile page after logging in. . Add the `spring-ai-elevenlabs` dependency to your project's build file. For more information, refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section. == Auto-configuration Spring AI provides Spring Boot auto-configuration for the ElevenLabs Text-to-Speech Client. To enable it, add the following dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-starter-model-elevenlabs ---- or to your Gradle `build.gradle` build file: [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-elevenlabs' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. == Speech Properties === Connection Properties The prefix `spring.ai.elevenlabs` is used as the property prefix for *all* ElevenLabs related configurations (both connection and TTS specific settings). This is defined in `ElevenLabsConnectionProperties`. [cols="3,5,1"] |==== | Property | Description | Default | spring.ai.elevenlabs.base-url | The base URL for the ElevenLabs API. | https://api.elevenlabs.io | spring.ai.elevenlabs.api-key | Your ElevenLabs API key. | - |==== === Configuration Properties [NOTE] ==== Enabling and disabling of the audio speech auto-configurations are now configured via top level properties with the prefix `spring.ai.model.audio.speech`. To enable, spring.ai.model.audio.speech=elevenlabs (It is enabled by default) To disable, spring.ai.model.audio.speech=none (or any value which doesn't match elevenlabs) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.elevenlabs.tts` is used as the property prefix to configure the ElevenLabs Text-to-Speech client, specifically. This is defined in `ElevenLabsSpeechProperties`. [cols="3,5,2"] |==== | Property | Description | Default | spring.ai.model.audio.speech | Enable Audio Speech Model | elevenlabs | spring.ai.elevenlabs.tts.options.model-id | The ID of the model to use. | eleven_turbo_v2_5 | spring.ai.elevenlabs.tts.options.voice-id | The ID of the voice to use. This is the *voice ID*, not the voice name. | 9BWtsMINqrJLrRacOk9x | spring.ai.elevenlabs.tts.options.output-format | The output format for the generated audio. See xref:#output-formats[Output Formats] below. | mp3_22050_32 |==== NOTE: The base URL and API key can also be configured *specifically* for TTS using `spring.ai.elevenlabs.tts.base-url` and `spring.ai.elevenlabs.tts.api-key`. However, it is generally recommended to use the global `spring.ai.elevenlabs` prefix for simplicity, unless you have a specific reason to use different credentials for different ElevenLabs services. The more specific `tts` properties will override the global ones. TIP: All properties prefixed with `spring.ai.elevenlabs.tts.options` can be overridden at runtime. [[output-formats]] .Available Output Formats [cols="1,1"] |==== | Enum Value | Description | MP3_22050_32 | MP3, 22.05 kHz, 32 kbps | MP3_44100_32 | MP3, 44.1 kHz, 32 kbps | MP3_44100_64 | MP3, 44.1 kHz, 64 kbps | MP3_44100_96 | MP3, 44.1 kHz, 96 kbps | MP3_44100_128 | MP3, 44.1 kHz, 128 kbps | MP3_44100_192 | MP3, 44.1 kHz, 192 kbps | PCM_8000 | PCM, 8 kHz | PCM_16000 | PCM, 16 kHz | PCM_22050 | PCM, 22.05 kHz | PCM_24000 | PCM, 24 kHz | PCM_44100 | PCM, 44.1 kHz | PCM_48000 | PCM, 48 kHz | ULAW_8000 | µ-law, 8 kHz | ALAW_8000 | A-law, 8 kHz | OPUS_48000_32 | Opus, 48 kHz, 32 kbps | OPUS_48000_64 | Opus, 48 kHz, 64 kbps | OPUS_48000_96 | Opus, 48 kHz, 96 kbps | OPUS_48000_128 | Opus, 48 kHz, 128 kbps | OPUS_48000_192 | Opus, 48 kHz, 192 kbps |==== == Runtime Options [[speech-options]] The `ElevenLabsTextToSpeechOptions` class provides options to use when making a text-to-speech request. 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: * `modelId`: The ID of the model to use. * `voiceId`: The ID of the voice to use. * `outputFormat`: The output format of the generated audio. * `voiceSettings`: An object containing voice settings such as `stability`, `similarityBoost`, `style`, `useSpeakerBoost`, and `speed`. * `enableLogging`: A boolean to enable or disable logging. * `languageCode`: The language code of the input text (e.g., "en" for English). * `pronunciationDictionaryLocators`: A list of pronunciation dictionary locators. * `seed`: A seed for random number generation, for reproducibility. * `previousText`: Text before the main text, for context in multi-turn conversations. * `nextText`: Text after the main text, for context in multi-turn conversations. * `previousRequestIds`: Request IDs from previous turns in a conversation. * `nextRequestIds`: Request IDs for subsequent turns in a conversation. * `applyTextNormalization`: Apply text normalization ("auto", "on", or "off"). * `applyLanguageTextNormalization`: Apply language text normalization. For example: [source,java] ---- ElevenLabsTextToSpeechOptions speechOptions = ElevenLabsTextToSpeechOptions.builder() .model("eleven_multilingual_v2") .voiceId("your_voice_id") .outputFormat(ElevenLabsApi.OutputFormat.MP3_44100_128.getValue()) .build(); TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("Hello, this is a text-to-speech example.", speechOptions); TextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt); ---- === Using Voice Settings You can customize the voice output by providing `VoiceSettings` in the options. This allows you to control properties like stability and similarity. [source,java] ---- var voiceSettings = new ElevenLabsApi.SpeechRequest.VoiceSettings(0.75f, 0.75f, 0.0f, true); ElevenLabsTextToSpeechOptions speechOptions = ElevenLabsTextToSpeechOptions.builder() .model("eleven_multilingual_v2") .voiceId("your_voice_id") .voiceSettings(voiceSettings) .build(); TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("This is a test with custom voice settings!", speechOptions); TextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt); ---- == Manual Configuration Add the `spring-ai-elevenlabs` dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-elevenlabs ---- or to your Gradle `build.gradle` build file: [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-elevenlabs' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Next, create an `ElevenLabsTextToSpeechModel`: [source,java] ---- ElevenLabsApi elevenLabsApi = ElevenLabsApi.builder() .apiKey(System.getenv("ELEVEN_LABS_API_KEY")) .build(); ElevenLabsTextToSpeechModel elevenLabsTextToSpeechModel = ElevenLabsTextToSpeechModel.builder() .elevenLabsApi(elevenLabsApi) .defaultOptions(ElevenLabsTextToSpeechOptions.builder() .model("eleven_turbo_v2_5") .voiceId("your_voice_id") // e.g. "9BWtsMINqrJLrRacOk9x" .outputFormat("mp3_44100_128") .build()) .build(); // The call will use the default options configured above. TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("Hello, this is a text-to-speech example."); TextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt); byte[] responseAsBytes = response.getResult().getOutput(); ---- == Streaming Real-time Audio The 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. [source,java] ---- ElevenLabsApi elevenLabsApi = ElevenLabsApi.builder() .apiKey(System.getenv("ELEVEN_LABS_API_KEY")) .build(); ElevenLabsTextToSpeechModel elevenLabsTextToSpeechModel = ElevenLabsTextToSpeechModel.builder() .elevenLabsApi(elevenLabsApi) .build(); ElevenLabsTextToSpeechOptions streamingOptions = ElevenLabsTextToSpeechOptions.builder() .model("eleven_turbo_v2_5") .voiceId("your_voice_id") .outputFormat("mp3_44100_128") .build(); TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("Today is a wonderful day to build something people love!", streamingOptions); Flux responseStream = elevenLabsTextToSpeechModel.stream(speechPrompt); // Process the stream, e.g., play the audio chunks responseStream.subscribe(speechResponse -> { byte[] audioChunk = speechResponse.getResult().getOutput(); // Play the audioChunk }); ---- == Voices API The 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. To use the Voices API, you'll need to create an instance of `ElevenLabsVoicesApi`: [source,java] ---- ElevenLabsVoicesApi voicesApi = ElevenLabsVoicesApi.builder() .apiKey(System.getenv("ELEVEN_LABS_API_KEY")) .build(); ---- You can then use the following methods: * `getVoices()`: Retrieves a list of all available voices. * `getDefaultVoiceSettings()`: Gets the default settings for voices. * `getVoiceSettings(String voiceId)`: Returns the settings for a specific voice. * `getVoice(String voiceId)`: Returns metadata about a specific voice. Example: [source,java] ---- // Get all voices ResponseEntity voicesResponse = voicesApi.getVoices(); List voices = voicesResponse.getBody().voices(); // Get default voice settings ResponseEntity defaultSettingsResponse = voicesApi.getDefaultVoiceSettings(); ElevenLabsVoicesApi.VoiceSettings defaultSettings = defaultSettingsResponse.getBody(); // Get settings for a specific voice ResponseEntity voiceSettingsResponse = voicesApi.getVoiceSettings(voiceId); ElevenLabsVoicesApi.VoiceSettings voiceSettings = voiceSettingsResponse.getBody(); // Get details for a specific voice ResponseEntity voiceDetailsResponse = voicesApi.getVoice(voiceId); ElevenLabsVoicesApi.Voice voiceDetails = voiceDetailsResponse.getBody(); ---- == Example Code * 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. * 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`. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/audio/speech/openai-speech.adoc ================================================ = OpenAI Text-to-Speech (TTS) == Introduction The Audio API provides a speech endpoint based on OpenAI's TTS (text-to-speech) model, enabling users to: - Narrate a written blog post. - Produce spoken audio in multiple languages. - Give real-time audio output using streaming. [NOTE] ==== Starting 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]. ==== == Prerequisites . 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]. . 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the OpenAI Text-to-Speech Client. To enable it add the following dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- or to your Gradle `build.gradle` build file: [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. == Speech Properties === Connection Properties The prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI. [cols="3,5,1"] |==== | Property | Description | Default | spring.ai.openai.base-url | The URL to connect to | https://api.openai.com | spring.ai.openai.api-key | The API Key | - | spring.ai.openai.organization-id | Optionally you can specify which organization used for an API request. | - | spring.ai.openai.project-id | Optionally, you can specify which project is used for an API request. | - |==== TIP: 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. Usage from these API requests will count as usage for the specified organization and project. === Configuration Properties [NOTE] ==== Enabling and disabling of the audio speech auto-configurations are now configured via top level properties with the prefix `spring.ai.model.audio.speech`. To enable, spring.ai.model.audio.speech=openai (It is enabled by default) To disable, spring.ai.model.audio.speech=none (or any value which doesn't match openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.openai.audio.speech` is used as the property prefix that lets you configure the OpenAI Text-to-Speech client. [cols="3,5,2"] |==== | Property | Description | Default | spring.ai.model.audio.speech | Enable Audio Speech Model | openai | spring.ai.openai.audio.speech.base-url | The URL to connect to | https://api.openai.com | spring.ai.openai.audio.speech.api-key | The API Key | - | spring.ai.openai.audio.speech.organization-id | Optionally you can specify which organization used for an API request. | - | spring.ai.openai.audio.speech.project-id | Optionally, you can specify which project is used for an API request. | - | 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 | 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 | 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 | 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 | 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 |==== NOTE: 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. The `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. This is useful if you want to use different OpenAI accounts for different models and different model endpoints. TIP: All properties prefixed with `spring.ai.openai.audio.speech.options` can be overridden at runtime. === Custom API Paths For OpenAI-compatible APIs (such as LocalAI, Ollama with OpenAI compatibility, or custom proxies) that use different endpoint paths, you can configure the speech path: [source,properties] ---- spring.ai.openai.audio.speech.speech-path=/custom/path/to/speech ---- This is particularly useful when: * Using API gateways or proxies that modify standard OpenAI paths * Working with OpenAI-compatible services that implement different URL structures * Testing against mock endpoints with custom paths * Deploying in environments with path-based routing requirements == Runtime Options [[speech-options]] The `OpenAiAudioSpeechOptions` class provides the options to use when making a text-to-speech request. On start-up, the options specified by `spring.ai.openai.audio.speech` are used but you can override these at runtime. The `OpenAiAudioSpeechOptions` class implements the `TextToSpeechOptions` interface, providing both portable and OpenAI-specific configuration options. For example: [source,java] ---- OpenAiAudioSpeechOptions speechOptions = OpenAiAudioSpeechOptions.builder() .model("gpt-4o-mini-tts") .voice(OpenAiAudioApi.SpeechRequest.Voice.ALLOY) .responseFormat(OpenAiAudioApi.SpeechRequest.AudioResponseFormat.MP3) .speed(1.0) .build(); TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("Hello, this is a text-to-speech example.", speechOptions); TextToSpeechResponse response = openAiAudioSpeechModel.call(speechPrompt); ---- == Manual Configuration Add the `spring-ai-openai` dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-openai ---- or to your Gradle `build.gradle` build file: [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Next, create an `OpenAiAudioSpeechModel`: [source,java] ---- var openAiAudioApi = new OpenAiAudioApi() .apiKey(System.getenv("OPENAI_API_KEY")) .build(); var openAiAudioSpeechModel = new OpenAiAudioSpeechModel(openAiAudioApi); var speechOptions = OpenAiAudioSpeechOptions.builder() .responseFormat(OpenAiAudioApi.SpeechRequest.AudioResponseFormat.MP3) .speed(1.0) .model(OpenAiAudioApi.TtsModel.GPT_4_O_MINI_TTS.value) .build(); var speechPrompt = new TextToSpeechPrompt("Hello, this is a text-to-speech example.", speechOptions); TextToSpeechResponse response = openAiAudioSpeechModel.call(speechPrompt); // Accessing metadata (rate limit info) OpenAiAudioSpeechResponseMetadata metadata = (OpenAiAudioSpeechResponseMetadata) response.getMetadata(); byte[] responseAsBytes = response.getResult().getOutput(); ---- == Streaming Real-time Audio The 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. The `OpenAiAudioSpeechModel` implements the `StreamingTextToSpeechModel` interface, providing both standard and streaming capabilities. [source,java] ---- var openAiAudioApi = new OpenAiAudioApi() .apiKey(System.getenv("OPENAI_API_KEY")) .build(); var openAiAudioSpeechModel = new OpenAiAudioSpeechModel(openAiAudioApi); OpenAiAudioSpeechOptions speechOptions = OpenAiAudioSpeechOptions.builder() .voice(OpenAiAudioApi.SpeechRequest.Voice.ALLOY) .speed(1.0) .responseFormat(OpenAiAudioApi.SpeechRequest.AudioResponseFormat.MP3) .model(OpenAiAudioApi.TtsModel.GPT_4_O_MINI_TTS.value) .build(); TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("Today is a wonderful day to build something people love!", speechOptions); Flux responseStream = openAiAudioSpeechModel.stream(speechPrompt); // You can also stream raw audio bytes directly Flux audioByteStream = openAiAudioSpeechModel.stream("Hello, world!"); ---- == Migration Guide If you're upgrading from the deprecated `SpeechModel` and `SpeechPrompt` classes, this guide provides detailed instructions for migrating to the new shared interfaces. === Breaking Changes Summary This migration includes the following breaking changes: 1. **Removed Classes**: Six deprecated classes have been removed from `org.springframework.ai.openai.audio.speech` package 2. **Package Changes**: Core TTS classes moved to `org.springframework.ai.audio.tts` package 3. **Type Changes**: The `speed` parameter changed from `Float` to `Double` across all OpenAI TTS components 4. **Interface Hierarchy**: `TextToSpeechModel` now extends `StreamingTextToSpeechModel` === Class Mapping Reference [cols="1,1"] |==== | Deprecated (Removed) | New Interface | `SpeechModel` | `TextToSpeechModel` | `StreamingSpeechModel` | `StreamingTextToSpeechModel` | `SpeechPrompt` | `TextToSpeechPrompt` | `SpeechResponse` | `TextToSpeechResponse` | `SpeechMessage` | `TextToSpeechMessage` | `Speech` (in `org.springframework.ai.openai.audio.speech`) | `Speech` (in `org.springframework.ai.audio.tts`) |==== === Step-by-Step Migration Instructions ==== Step 1: Update Imports Replace all imports from the old `org.springframework.ai.openai.audio.speech` package with the new shared interfaces: [source,text] ---- Find: import org.springframework.ai.openai.audio.speech.SpeechModel; Replace: import org.springframework.ai.audio.tts.TextToSpeechModel; Find: import org.springframework.ai.openai.audio.speech.StreamingSpeechModel; Replace: import org.springframework.ai.audio.tts.StreamingTextToSpeechModel; Find: import org.springframework.ai.openai.audio.speech.SpeechPrompt; Replace: import org.springframework.ai.audio.tts.TextToSpeechPrompt; Find: import org.springframework.ai.openai.audio.speech.SpeechResponse; Replace: import org.springframework.ai.audio.tts.TextToSpeechResponse; Find: import org.springframework.ai.openai.audio.speech.SpeechMessage; Replace: import org.springframework.ai.audio.tts.TextToSpeechMessage; Find: import org.springframework.ai.openai.audio.speech.Speech; Replace: import org.springframework.ai.audio.tts.Speech; ---- ==== Step 2: Update Type References Replace all type references in your code: [source,text] ---- Find: SpeechModel Replace: TextToSpeechModel Find: StreamingSpeechModel Replace: StreamingTextToSpeechModel Find: SpeechPrompt Replace: TextToSpeechPrompt Find: SpeechResponse Replace: TextToSpeechResponse Find: SpeechMessage Replace: TextToSpeechMessage ---- ==== Step 3: Update Speed Parameter (Float → Double) The `speed` parameter has changed from `Float` to `Double`. Update all occurrences: [source,text] ---- Find: .speed(1.0f) Replace: .speed(1.0) Find: .speed(0.5f) Replace: .speed(0.5) Find: Float speed Replace: Double speed ---- If you have serialized data or configuration files with Float values, you'll need to update those as well: [source,json] ---- // Before { "speed": 1.0 } // After (no code change needed for JSON, but be aware of type change in Java) { "speed": 1.0 } ---- ==== Step 4: Update Bean Declarations If you have Spring Boot auto-configuration or manual bean definitions: [source,java] ---- // Before @Bean public SpeechModel speechModel(OpenAiAudioApi audioApi) { return new OpenAiAudioSpeechModel(audioApi);

// Process audio chunk }); ---- ==== Example 4: Dependency Injection with Spring Boot **Before (deprecated):** [source,java] ---- @RestController public class OldSpeechController { private final SpeechModel speechModel; @Autowired public OldSpeechController(SpeechModel speechModel) { this.speechModel = speechModel; } @PostMapping("/narrate") public ResponseEntity narrate(@RequestBody String text) { SpeechPrompt prompt = new SpeechPrompt(text); SpeechResponse response = speechModel.call(prompt); return ResponseEntity.ok() .contentType(MediaType.parseMediaType("audio/mpeg")) .body(response.getResult().getOutput()); } } ---- **After (using shared interfaces):** [source,java] ---- @RestController public class SpeechController { private final TextToSpeechModel textToSpeechModel; @Autowired public SpeechController(TextToSpeechModel textToSpeechModel) { this.textToSpeechModel = textToSpeechModel; } @PostMapping("/narrate") public ResponseEntity narrate(@RequestBody String text) { TextToSpeechPrompt prompt = new TextToSpeechPrompt(text); TextToSpeechResponse response = textToSpeechModel.call(prompt); return ResponseEntity.ok() .contentType(MediaType.parseMediaType("audio/mpeg")) .body(response.getResult().getOutput()); } } ---- === Spring Boot Configuration Changes The Spring Boot auto-configuration properties remain the same. No changes are required to your `application.properties` or `application.yml` files. However, if you have explicit bean references or qualifiers, update them: [source,java] ---- // Before @Qualifier("speechModel") // After @Qualifier("textToSpeechModel") ---- === Benefits of the Migration - **Portability**: Write code once, switch between OpenAI, ElevenLabs, or other TTS providers easily - **Consistency**: Same patterns as ChatModel and other Spring AI abstractions - **Type Safety**: Improved type hierarchy with proper interface implementations - **Future-Proof**: New TTS providers will automatically work with your existing code - **Standardization**: Consistent `Double` type for speed parameter across all TTS providers === Common Migration Issues and Solutions ==== Issue 1: Compilation Error - Cannot Find Symbol SpeechModel **Error:** [source] ---- error: cannot find symbol SpeechModel ---- **Solution:** Update your imports as described in Step 1, changing `SpeechModel` to `TextToSpeechModel`. ==== Issue 2: Type Mismatch - Float Cannot Be Converted to Double **Error:** [source] ---- error: incompatible types: float cannot be converted to Double ---- **Solution:** Remove the `f` suffix from floating-point literals (e.g., change `1.0f` to `1.0`). ==== Issue 3: Bean Creation Error at Runtime **Error:** [source] ---- NoSuchBeanDefinitionException: No qualifying bean of type 'SpeechModel' ---- **Solution:** Update your dependency injection to use `TextToSpeechModel` instead of `SpeechModel`. == Example Code * The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/audio/speech/OpenAiSpeechModelIT.java[OpenAiSpeechModelIT.java] test provides some general examples of how to use the library. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/audio/speech.adoc ================================================ [[Speech]] = Text-To-Speech (TTS) API Spring 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. == Supported Providers - xref:api/audio/speech/openai-speech.adoc[OpenAI's Speech API] - xref:api/audio/speech/elevenlabs-speech.adoc[Eleven Labs Text-To-Speech API] == Common Interface All TTS providers implement the following shared interfaces: === TextToSpeechModel The `TextToSpeechModel` interface provides methods for converting text to speech: [source,java] ---- public interface TextToSpeechModel extends Model, StreamingTextToSpeechModel { /** * Converts text to speech with default options. */ default byte[] call(String text) { // Default implementation } /** * Converts text to speech with custom options. */ TextToSpeechResponse call(TextToSpeechPrompt prompt); /** * Returns the default options for this model. */ default TextToSpeechOptions getDefaultOptions() { // Default implementation } } ---- === StreamingTextToSpeechModel The `StreamingTextToSpeechModel` interface provides methods for streaming audio in real-time: [source,java] ---- @FunctionalInterface public interface StreamingTextToSpeechModel extends StreamingModel { /** * Streams text-to-speech responses with metadata. */ Flux stream(TextToSpeechPrompt prompt); /** * Streams audio bytes for the given text. */ default Flux stream(String text) { // Default implementation } } ---- === TextToSpeechPrompt The `TextToSpeechPrompt` class encapsulates the input text and options: [source,java] ---- TextToSpeechPrompt prompt = new TextToSpeechPrompt( "Hello, this is a text-to-speech example.", options ); ---- === TextToSpeechResponse The `TextToSpeechResponse` class contains the generated audio and metadata: [source,java] ---- TextToSpeechResponse response = model.call(prompt); byte[] audioBytes = response.getResult().getOutput(); TextToSpeechResponseMetadata metadata = response.getMetadata(); ---- == Writing Provider-Agnostic Code One 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. === Basic Service Example The shared interfaces allow you to write code that works with any TTS provider: [source,java] ---- @Service public class NarrationService { private final TextToSpeechModel textToSpeechModel; public NarrationService(TextToSpeechModel textToSpeechModel) { this.textToSpeechModel = textToSpeechModel; } public byte[] narrate(String text) { // Works with any TTS provider return textToSpeechModel.call(text); } public byte[] narrateWithOptions(String text, TextToSpeechOptions options) { TextToSpeechPrompt prompt = new TextToSpeechPrompt(text, options); TextToSpeechResponse response = textToSpeechModel.call(prompt); return response.getResult().getOutput(); } } ---- This service works seamlessly with OpenAI, ElevenLabs, or any other TTS provider, with the actual implementation determined by your Spring Boot configuration. === Advanced Example: Multi-Provider Support You can build applications that support multiple TTS providers simultaneously: [source,java] ---- @Service public class MultiProviderNarrationService { private final Map providers; public MultiProviderNarrationService(List models) { // Spring will inject all available TextToSpeechModel beans this.providers = models.stream() .collect(Collectors.toMap( model -> model.getClass().getSimpleName(), model -> model )); } public byte[] narrateWithProvider(String text, String providerName) { TextToSpeechModel model = providers.get(providerName); if (model == null) { throw new IllegalArgumentException("Unknown provider: " + providerName); } return model.call(text); } public Set getAvailableProviders() { return providers.keySet(); } } ---- === Streaming Audio Example The shared interfaces also support streaming for real-time audio generation: [source,java] ---- @Service public class StreamingNarrationService { private final TextToSpeechModel textToSpeechModel; public StreamingNarrationService(TextToSpeechModel textToSpeechModel) { this.textToSpeechModel = textToSpeechModel; } public Flux streamNarration(String text) { // TextToSpeechModel extends StreamingTextToSpeechModel return textToSpeechModel.stream(text); } public Flux streamWithMetadata(String text, TextToSpeechOptions options) { TextToSpeechPrompt prompt = new TextToSpeechPrompt(text, options); return textToSpeechModel.stream(prompt); } } ---- === REST Controller Example Building a REST API with provider-agnostic TTS: [source,java] ---- @RestController @RequestMapping("/api/tts") public class TextToSpeechController { private final TextToSpeechModel textToSpeechModel; public TextToSpeechController(TextToSpeechModel textToSpeechModel) { this.textToSpeechModel = textToSpeechModel; } @PostMapping(value = "/synthesize", produces = "audio/mpeg") public ResponseEntity synthesize(@RequestBody SynthesisRequest request) { byte[] audio = textToSpeechModel.call(request.text()); return ResponseEntity.ok() .contentType(MediaType.parseMediaType("audio/mpeg")) .header("Content-Disposition", "attachment; filename=\"speech.mp3\"") .body(audio); } @GetMapping(value = "/stream", produces = MediaType.APPLICATION_OCTET_STREAM_VALUE) public Flux streamSynthesis(@RequestParam String text) { return textToSpeechModel.stream(text); } record SynthesisRequest(String text) {} } ---- === Configuration-Based Provider Selection Switch between providers using Spring profiles or properties: [source,yaml] ---- # application-openai.yml spring: ai: model: audio: speech: openai openai: api-key: ${OPENAI_API_KEY} audio: speech: options: model: gpt-4o-mini-tts voice: alloy # application-elevenlabs.yml spring: ai: model: audio: speech: elevenlabs elevenlabs: api-key: ${ELEVENLABS_API_KEY} tts: options: model-id: eleven_turbo_v2_5 voice-id: your_voice_id ---- Then activate the desired provider: [source,bash] ---- # Use OpenAI java -jar app.jar --spring.profiles.active=openai # Use ElevenLabs java -jar app.jar --spring.profiles.active=elevenlabs ---- === Using Portable Options For maximum portability, use only the common `TextToSpeechOptions` interface methods: [source,java] ---- @Service public class PortableNarrationService { private final TextToSpeechModel textToSpeechModel; public PortableNarrationService(TextToSpeechModel textToSpeechModel) { this.textToSpeechModel = textToSpeechModel; } public byte[] createPortableNarration(String text) { // Use provider's default options for maximum portability TextToSpeechOptions defaultOptions = textToSpeechModel.getDefaultOptions(); TextToSpeechPrompt prompt = new TextToSpeechPrompt(text, defaultOptions); TextToSpeechResponse response = textToSpeechModel.call(prompt); return response.getResult().getOutput(); } } ---- === Working with Provider-Specific Features When you need provider-specific features, you can still use them while maintaining a portable codebase: [source,java] ---- @Service public class FlexibleNarrationService { private final TextToSpeechModel textToSpeechModel; public FlexibleNarrationService(TextToSpeechModel textToSpeechModel) { this.textToSpeechModel = textToSpeechModel; } public byte[] narrate(String text, TextToSpeechOptions baseOptions) { TextToSpeechOptions options = baseOptions; // Apply provider-specific optimizations if available if (textToSpeechModel instanceof OpenAiAudioSpeechModel) { options = OpenAiAudioSpeechOptions.builder() .from(baseOptions) .model("gpt-4o-tts") // OpenAI-specific: use high-quality model .speed(1.0) .build(); } else if (textToSpeechModel instanceof ElevenLabsTextToSpeechModel) { // ElevenLabs-specific options could go here } TextToSpeechPrompt prompt = new TextToSpeechPrompt(text, options); TextToSpeechResponse response = textToSpeechModel.call(prompt); return response.getResult().getOutput(); } } ---- === Best Practices for Portable Code 1. **Depend on Interfaces**: Always inject `TextToSpeechModel` rather than concrete implementations 2. **Use Common Options**: Stick to `TextToSpeechOptions` interface methods for maximum portability 3. **Handle Metadata Gracefully**: Different providers return different metadata; handle it generically 4. **Test with Multiple Providers**: Ensure your code works with at least two TTS providers 5. **Document Provider Assumptions**: If you rely on specific provider behavior, document it clearly == Provider-Specific Features While 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. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/audio/transcriptions/azure-openai-transcriptions.adoc ================================================ = Azure OpenAI Transcriptions Spring AI supports https://learn.microsoft.com/en-us/azure/ai-services/openai/whisper-quickstart?tabs=command-line%2Cpython-new&pivots=rest-api[Azure Whisper model]. == Prerequisites Obtain your Azure OpenAI `endpoint` and `api-key` from the Azure OpenAI Service section on the link:https://portal.azure.com[Azure Portal].

If set to 0, the model will use log probability to automatically increase the temperature until certain thresholds are hit. | 0 | spring.ai.openai.audio.transcription.options.timestamp_granularities | The timestamp granularities to populate for this transcription. response_format must be set verbose_json to use timestamp granularities. Either or both of these options are supported: word, or segment. Note: There is no additional latency for segment timestamps, but generating word timestamps incurs additional latency. | segment |==== NOTE: 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. The `spring.ai.openai.audio.transcription.base-url`, `spring.ai.openai.audio.transcription.api-key`, `spring.ai.openai.audio.transcription.organization-id` and `spring.ai.openai.audio.transcription.project-id` properties if set take precedence over the common properties. This is useful if you want to use different OpenAI accounts for different models and different model endpoints. TIP: All properties prefixed with `spring.ai.openai.transcription.options` can be overridden at runtime. === Custom API Paths For OpenAI-compatible APIs (such as LocalAI, Ollama with OpenAI compatibility, or custom proxies) that use different endpoint paths, you can configure the transcription path: [source,properties] ---- spring.ai.openai.audio.transcription.transcription-path=/custom/path/to/transcriptions ---- This is particularly useful when: * Using API gateways or proxies that modify standard OpenAI paths * Working with OpenAI-compatible services that implement different URL structures * Testing against mock endpoints with custom paths * Deploying in environments with path-based routing requirements == Runtime Options [[transcription-options]] The `OpenAiAudioTranscriptionOptions` class provides the options to use when making a transcription. On start-up, the options specified by `spring.ai.openai.audio.transcription` are used but you can override these at runtime. For example: [source,java] ---- OpenAiAudioApi.TranscriptResponseFormat responseFormat = OpenAiAudioApi.TranscriptResponseFormat.VTT; OpenAiAudioTranscriptionOptions transcriptionOptions = OpenAiAudioTranscriptionOptions.builder() .language("en") .prompt("Ask not this, but ask that") .temperature(0f) .responseFormat(this.responseFormat) .build(); AudioTranscriptionPrompt transcriptionRequest = new AudioTranscriptionPrompt(audioFile, this.transcriptionOptions); AudioTranscriptionResponse response = openAiTranscriptionModel.call(this.transcriptionRequest); ---- == Manual Configuration Add the `spring-ai-openai` dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-openai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Next, create a `OpenAiAudioTranscriptionModel` [source,java] ---- var openAiAudioApi = new OpenAiAudioApi(System.getenv("OPENAI_API_KEY")); var openAiAudioTranscriptionModel = new OpenAiAudioTranscriptionModel(this.openAiAudioApi); var transcriptionOptions = OpenAiAudioTranscriptionOptions.builder() .responseFormat(TranscriptResponseFormat.TEXT) .temperature(0f) .build(); var audioFile = new FileSystemResource("/path/to/your/resource/speech/jfk.flac"); AudioTranscriptionPrompt transcriptionRequest = new AudioTranscriptionPrompt(this.audioFile, this.transcriptionOptions); AudioTranscriptionResponse response = openAiTranscriptionModel.call(this.transcriptionRequest); ---- == Example Code * The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/audio/transcription/OpenAiTranscriptionModelIT.java[OpenAiTranscriptionModelIT.java] test provides some general examples how to use the library. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/audio/transcriptions.adoc ================================================ [[Transcription]] = Transcription API Spring 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. == Supported Providers - xref:api/audio/transcriptions/openai-transcriptions.adoc[OpenAI's Whisper API] - xref:api/audio/transcriptions/azure-openai-transcriptions.adoc[Azure OpenAI Whisper API] == Common Interface All transcription providers implement the following shared interface: === TranscriptionModel The `TranscriptionModel` interface provides methods for converting audio to text: [source,java] ---- public interface TranscriptionModel extends Model { /** * Transcribes the audio from the given prompt. */ AudioTranscriptionResponse call(AudioTranscriptionPrompt transcriptionPrompt); /** * A convenience method for transcribing an audio resource. */ default String transcribe(Resource resource) { AudioTranscriptionPrompt prompt = new AudioTranscriptionPrompt(resource); return this.call(prompt).getResult().getOutput(); } /** * A convenience method for transcribing an audio resource with options. */ default String transcribe(Resource resource, AudioTranscriptionOptions options) { AudioTranscriptionPrompt prompt = new AudioTranscriptionPrompt(resource, options); return this.call(prompt).getResult().getOutput(); } } ---- === AudioTranscriptionPrompt The `AudioTranscriptionPrompt` class encapsulates the input audio and options: [source,java] ---- Resource audioFile = new FileSystemResource("/path/to/audio.mp3"); AudioTranscriptionPrompt prompt = new AudioTranscriptionPrompt( audioFile, options ); ---- === AudioTranscriptionResponse The `AudioTranscriptionResponse` class contains the transcribed text and metadata: [source,java] ---- AudioTranscriptionResponse response = model.call(prompt); String transcribedText = response.getResult().getOutput(); AudioTranscriptionResponseMetadata metadata = response.getMetadata(); ---- == Writing Provider-Agnostic Code One 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. === Basic Service Example The shared interface allows you to write code that works with any transcription provider: [source,java] ---- @Service public class TranscriptionService { private final TranscriptionModel transcriptionModel; public TranscriptionService(TranscriptionModel transcriptionModel) { this.transcriptionModel = transcriptionModel; } public String transcribeAudio(Resource audioFile) { return transcriptionModel.transcribe(audioFile); } public String transcribeWithOptions(Resource audioFile, AudioTranscriptionOptions options) { AudioTranscriptionPrompt prompt = new AudioTranscriptionPrompt(audioFile, options); AudioTranscriptionResponse response = transcriptionModel.call(prompt); return response.getResult().getOutput(); } } ---- This service works seamlessly with OpenAI, Azure OpenAI, or any other transcription provider, with the actual implementation determined by your Spring Boot configuration. == Provider-Specific Features While 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. For detailed information about provider-specific features, see the individual provider documentation pages. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/bedrock-chat.adoc ================================================ include::bedrock.adoc[] ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/bedrock.adoc ================================================ = Amazon Bedrock [NOTE] ==== Following the Bedrock recommendations, Spring AI transitioned to using Amazon Bedrock's Converse API for all Chat conversation implementations in Spring AI. The xref:api/chat/bedrock-converse.adoc[Bedrock Converse API] has the following key benefits: - Unified Interface: Write your code once and use it with any supported Amazon Bedrock model - Model Flexibility: Seamlessly switch between different conversation models without code changes - Extended Functionality: Support for model-specific parameters through dedicated structures - Tool Support: Native integration with function calling and tool usage capabilities - Multimodal Capabilities: Built-in support for vision and other multimodal features - Future-Proof: Aligned with Amazon Bedrock's recommended best practices The Converse API does not support embedding operations, so these will remain in the current API and the embedding model functionality in the existing `InvokeModel API` will be maintained ==== link:https://docs.aws.amazon.com/bedrock/latest/userguide/what-is-bedrock.html[Amazon Bedrock] is a managed service that provides foundation models from various AI providers, available through a unified API. Spring AI supports https://docs.aws.amazon.com/bedrock/latest/userguide/model-ids-arns.html[the Embedding AI models] available through Amazon Bedrock by implementing the Spring `EmbeddingModel` interface. Additionally, Spring AI provides Spring Auto-Configurations and Boot Starters for all clients, making it easy to bootstrap and configure for the Bedrock models. == Getting Started There are a few steps to get started * Add the Spring Boot starter for Bedrock to your project. * Obtain AWS credentials: If you don't have an AWS account and AWS CLI configured yet, this video guide can help you configure it: link:https://youtu.be/gswVHTrRX8I?si=buaY7aeI0l3-bBVb[AWS CLI & SDK Setup in Less Than 4 Minutes!]. You should be able to obtain your access and security keys. * 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. === Project Dependencies Then add the Spring Boot Starter dependency to your project's Maven `pom.xml` build file: [source,xml] ---- spring-ai-starter-model-bedrock org.springframework.ai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-bedrock' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Connect to AWS Bedrock Use the `BedrockAwsConnectionProperties` to configure AWS credentials and region: [source,shell] ---- spring.ai.bedrock.aws.region=us-east-1 spring.ai.bedrock.aws.access-key=YOUR_ACCESS_KEY spring.ai.bedrock.aws.secret-key=YOUR_SECRET_KEY spring.ai.bedrock.aws.profile.name=YOUR_PROFILE_NAME spring.ai.bedrock.aws.profile.credentials-path=YOUR_CREDENTIALS_PATH spring.ai.bedrock.aws.profile.configuration-path=YOUR_CONFIGURATION_PATH spring.ai.bedrock.aws.timeout=10m ---- The `region` property is compulsory. AWS credentials are resolved in the following order: 1. Spring-AI Bedrock `spring.ai.bedrock.aws.access-key` and `spring.ai.bedrock.aws.secret-key` properties. 2. Spring-AI Bedrock `spring.ai.bedrock.aws.profile.name`, If `spring.ai.bedrock.aws.profile.credentials-path` and `spring.ai.bedrock.aws.profile.configuration-path` are not specified, Spring AI use the standard AWS shared files: `~/.aws/credentials` for credentials and `~/.aws/config` for configuration. 3. Java System Properties - `aws.accessKeyId` and `aws.secretAccessKey`. 4. Environment Variables - `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`. 5. Web Identity Token credentials from system properties or environment variables. 6. Credential profiles file at the default location (`~/.aws/credentials`) shared by all AWS SDKs and the AWS CLI. 7. Credentials delivered through the Amazon EC2 container service if the `AWS_CONTAINER_CREDENTIALS_RELATIVE_URI` environment variable is set and the security manager has permission to access the variable. 8. Instance profile credentials delivered through the Amazon EC2 metadata service or set the `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` environment variables. AWS region is resolved in the following order: 1. Spring-AI Bedrock `spring.ai.bedrock.aws.region` property. 2. Java System Properties - `aws.region`. 3. Environment Variables - `AWS_REGION`. 4. Credential profiles file at the default location (`~/.aws/credentials`) shared by all AWS SDKs and the AWS CLI. 5. Instance profile region delivered through the Amazon EC2 metadata service. In addition to the standard Spring-AI Bedrock credentials and region properties configuration, Spring-AI provides support for custom `AwsCredentialsProvider` and `AwsRegionProvider` beans. NOTE: For example, using Spring-AI and https://spring.io/projects/spring-cloud-aws[Spring Cloud for Amazon Web Services] at the same time. Spring-AI is compatible with Spring Cloud for Amazon Web Services credential configuration. === Enable selected Bedrock model NOTE: By default, all models are disabled. You have to enable the chosen Bedrock models explicitly using the `spring.ai.bedrock..embedding.enabled=true` property. Here are the supported ``s: [cols="|,|,|,|"] |==== | Model | cohere | titan (no batch support yet) |==== For example, to enable the Bedrock Cohere embedding model, you need to set `spring.ai.bedrock.cohere.embedding.enabled=true`. Next, you can use the `spring.ai.bedrock..embedding.*` properties to configure each model as provided. For more information, refer to the documentation below for each supported model. * xref:api/embeddings/bedrock-cohere-embedding.adoc[Spring AI Bedrock Cohere Embeddings]: `spring.ai.bedrock.cohere.embedding.enabled=true` * xref:api/embeddings/bedrock-titan-embedding.adoc[Spring AI Bedrock Titan Embeddings]: `spring.ai.bedrock.titan.embedding.enabled=true` ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chat/anthropic-chat.adoc ================================================ = Anthropic Chat Spring AI supports Anthropic's Claude models through the official link:https://github.com/anthropics/anthropic-sdk-java[Anthropic Java SDK], providing access to Claude through Anthropic's API. == Prerequisites Create an account at the https://console.anthropic.com/[Anthropic Console] and generate an API key on the https://console.anthropic.com/settings/keys[API Keys page]. === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-Configuration Spring Boot auto-configuration is available via the `spring-ai-starter-model-anthropic` starter.

If true, Spring AI handles tool calls internally. | true | disableParallelToolUse | When true, the model will use at most one tool per response. | false |==== TIP: In addition to the model-specific https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-anthropic/src/main/java/org/springframework/ai/anthropic/AnthropicChatOptions.java[AnthropicChatOptions], 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()]. == Tool Calling You can register custom Java functions or methods with the `AnthropicChatModel` and have Claude intelligently choose to output a JSON object containing arguments to call one or many of the registered functions/tools. This is a powerful technique to connect the LLM capabilities with external tools and APIs. Read more about xref:api/tools.adoc[Tool Calling]. === Basic Tool Calling [source,java] ---- var chatOptions = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .toolCallbacks(List.of( FunctionToolCallback.builder("getCurrentWeather", new WeatherService()) .description("Get the weather in location") .inputType(WeatherService.Request.class) .build())) .build(); var chatModel = new AnthropicChatModel(chatOptions); ChatResponse response = chatModel.call( new Prompt("What's the weather like in San Francisco?", chatOptions)); ---- === Tool Choice Options Control how Claude uses tools with the `toolChoice` option: [source,java] ---- import com.anthropic.models.messages.ToolChoiceAny; import com.anthropic.models.messages.ToolChoiceTool; import com.anthropic.models.messages.ToolChoiceNone; // Force Claude to use any available tool var options = AnthropicChatOptions.builder() .toolChoice(ToolChoiceAny.builder().build()) .toolCallbacks(...) .build(); // Force Claude to use a specific tool var options = AnthropicChatOptions.builder() .toolChoice(ToolChoiceTool.builder().name("getCurrentWeather").build()) .toolCallbacks(...) .build(); // Prevent tool use entirely var options = AnthropicChatOptions.builder() .toolChoice(ToolChoiceNone.builder().build()) .toolCallbacks(...) .build(); ---- [TIP] ==== The Anthropic Java SDK provides convenient static factory methods for common tool choices, which can make your code more concise: * `ToolChoice.auto()` can be used instead of `ToolChoice.ofAuto(...)`. * `ToolChoice.any()` can be used instead of `ToolChoice.ofAny(...)`. * `ToolChoice.none()` can be used instead of `ToolChoice.ofNone(...)`. ==== === Streaming Tool Calling The Anthropic SDK module fully supports tool calling in streaming mode. When Claude decides to call a tool during streaming: 1. Tool call arguments are accumulated from partial JSON deltas 2. Tools are executed when the content block completes 3. Results are sent back to Claude 4. The conversation continues recursively until Claude provides a final response [source,java] ---- Flux stream = chatModel.stream( new Prompt("What's the weather in Paris, Tokyo, and New York?", chatOptions)); String response = stream .collectList() .block() .stream() .map(r -> r.getResult().getOutput().getContent()) .filter(Objects::nonNull) .collect(Collectors.joining()); ---- == Streaming The Anthropic SDK module supports both synchronous and streaming responses. Streaming allows Claude to return responses incrementally as they're generated. [source,java] ---- Flux stream = chatModel.stream(new Prompt("Tell me a story")); stream.subscribe(response -> { String content = response.getResult().getOutput().getContent(); if (content != null) { System.out.print(content); } }); ---- == Extended Thinking Anthropic 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. [NOTE] ==== *Supported Models* The thinking feature is supported by the following Claude models: * Claude 4 models (`claude-opus-4-20250514`, `claude-sonnet-4-20250514`) * Claude 3.7 Sonnet (`claude-3-7-sonnet-20250219`) *Model capabilities:* * *Claude 3.7 Sonnet*: Returns full thinking output. * *Claude 4 models*: Support summarized thinking and enhanced tool integration. API request structure is the same across all supported models, but output behavior varies. ==== === Thinking Configuration To enable thinking, configure the following: 1. **Set a thinking budget**: The `budgetTokens` must be >= 1024 and less than `maxTokens`. 2. **Set temperature to 1.0**: Required when thinking is enabled. === Convenience Builder Methods `AnthropicChatOptions.Builder` provides convenience methods for thinking configuration: [source,java] ---- // Enable thinking with a specific token budget var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .temperature(1.0) .maxTokens(16000) .thinkingEnabled(10000L) // budget must be >= 1024 and < maxTokens .build(); // Let Claude adaptively decide whether to think var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .thinkingAdaptive() .build(); // Explicitly disable thinking var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .thinkingDisabled() .build(); ---- You can also use the raw SDK `ThinkingConfigParam` directly: [source,java] ---- import com.anthropic.models.messages.ThinkingConfigParam; import com.anthropic.models.messages.ThinkingConfigEnabled; var options = AnthropicChatOptions.builder() .thinking(ThinkingConfigParam.ofEnabled( ThinkingConfigEnabled.builder().budgetTokens(10000L).build())) .build(); ---- === Thinking Display Setting By default, full thinking output is returned in the response. You can control this with the `display` parameter to reduce token costs: * **`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. * **`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. [source,java] ---- import com.anthropic.models.messages.ThinkingConfigEnabled; import com.anthropic.models.messages.ThinkingConfigAdaptive; // Enabled thinking with summarized display var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .temperature(1.0) .maxTokens(16000) .thinkingEnabled(10000L, ThinkingConfigEnabled.Display.SUMMARIZED) .build(); // Enabled thinking with omitted display var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .temperature(1.0) .maxTokens(16000) .thinkingEnabled(10000L, ThinkingConfigEnabled.Display.OMITTED) .build(); // Adaptive thinking with summarized display var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .temperature(1.0) .maxTokens(16000) .thinkingAdaptive(ThinkingConfigAdaptive.Display.SUMMARIZED) .build(); ---- NOTE: 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. === Non-streaming Example [source,java] ---- var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .temperature(1.0) .maxTokens(16000) .thinkingEnabled(10000L) .build(); ChatResponse response = chatModel.call( new Prompt("Are there an infinite number of prime numbers such that n mod 4 == 3?", options)); // The response contains multiple generations: // - ThinkingBlock generations (with "signature" in metadata) // - TextBlock generations (with the final answer) for (Generation generation : response.getResults()) { AssistantMessage message = generation.getOutput(); if (message.getMetadata().containsKey("signature")) { // This is a thinking block - contains Claude's reasoning System.out.println("Thinking: " + message.getText()); System.out.println("Signature: " + message.getMetadata().get("signature")); } else if (message.getMetadata().containsKey("data")) { // This is a redacted thinking block (safety-redacted reasoning) System.out.println("Redacted thinking data: " + message.getMetadata().get("data")); } else if (message.getText() != null && !message.getText().isBlank()) { // This is the final text response System.out.println("Answer: " + message.getText()); } } ---- === Streaming Example Thinking is fully supported in streaming mode. Thinking deltas and signature deltas are emitted as they arrive: [source,java] ---- var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .temperature(1.0) .maxTokens(16000) .thinkingEnabled(10000L) .build(); Flux stream = chatModel.stream( new Prompt("Are there an infinite number of prime numbers such that n mod 4 == 3?", options)); stream.subscribe(response -> { Generation generation = response.getResult(); AssistantMessage message = generation.getOutput(); if (message.getMetadata().containsKey("thinking")) { // Incremental thinking content System.out.print(message.getText()); } else if (message.getMetadata().containsKey("signature")) { // Thinking block signature (emitted at end of thinking) System.out.println("\nSignature: " + message.getMetadata().get("signature")); } else if (message.getText() != null) { // Final text content System.out.print(message.getText()); } }); ---- === Response Structure When thinking is enabled, the response contains different types of content: [cols="2,3,3", stripes=even] |==== | Content Type | Metadata Key | Description | **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")`. | **Redacted Thinking** | `data` | Safety-redacted reasoning. Contains only a `data` marker, no visible text. | **Signature (streaming)** | `signature` | In streaming mode, the signature arrives as a separate delta at the end of a thinking block. | **Thinking Delta (streaming)** | `thinking` | Incremental thinking text chunks during streaming. The `thinking` metadata key is set to `true`. | **Text Block** | _(none)_ | The final answer text in `getText()`. |==== == Multi-Modal Support The Anthropic SDK module supports multi-modal inputs, allowing you to send images and PDF documents alongside text in your prompts. === Image Input Send images to Claude for analysis using the `Media` class: [source,java] ---- var imageResource = new ClassPathResource("/test-image.png"); var userMessage = UserMessage.builder() .text("What do you see in this image?") .media(List.of(new Media(MimeTypeUtils.IMAGE_PNG, imageResource))) .build(); ChatResponse response = chatModel.call(new Prompt(List.of(userMessage))); ---- Supported image formats: PNG, JPEG, GIF, WebP. Images can be provided as: * Byte arrays (automatically base64-encoded) * HTTPS URLs (passed directly to the API) === PDF Document Input Send PDF documents for Claude to analyze: [source,java] ---- var pdfResource = new ClassPathResource("/document.pdf"); var userMessage = UserMessage.builder() .text("Please summarize this document.") .media(List.of(new Media(new MimeType("application", "pdf"), pdfResource))) .build(); ChatResponse response = chatModel.call(new Prompt(List.of(userMessage))); ---- === Multiple Media Items You can include multiple images or documents in a single message: [source,java] ---- var userMessage = UserMessage.builder() .text("Compare these two images.") .media(List.of( new Media(MimeTypeUtils.IMAGE_PNG, image1Resource), new Media(MimeTypeUtils.IMAGE_PNG, image2Resource))) .build(); ---- == Citations Anthropic'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. When 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. Citations help improve: * **Accuracy verification**: Users can verify Claude's responses against source material * **Transparency**: See exactly which parts of documents informed the response * **Compliance**: Meet requirements for source attribution in regulated industries * **Trust**: Build confidence by showing where information came from [NOTE] ==== *Supported Models* Citations are supported on Claude 3.7 Sonnet and Claude 4 models (Opus and Sonnet). *Document Types* Three types of citation documents are supported: * **Plain Text**: Text content with character-level citations * **PDF**: PDF documents with page-level citations * **Custom Content**: User-defined content blocks with block-level citations ==== === Creating Citation Documents Use the `AnthropicCitationDocument` builder to create documents that can be cited: ==== Plain Text Documents [source,java] ---- AnthropicCitationDocument document = AnthropicCitationDocument.builder() .plainText("The Eiffel Tower was completed in 1889 in Paris, France. " + "It stands 330 meters tall and was designed by Gustave Eiffel.") .title("Eiffel Tower Facts") .citationsEnabled(true) .build(); ---- ==== PDF Documents [source,java] ---- // From file path AnthropicCitationDocument document = AnthropicCitationDocument.builder() .pdfFile("path/to/document.pdf") .title("Technical Specification") .citationsEnabled(true) .build(); // From byte array byte[] pdfBytes = loadPdfBytes(); AnthropicCitationDocument document = AnthropicCitationDocument.builder() .pdf(pdfBytes) .title("Product Manual") .citationsEnabled(true) .build(); ---- ==== Custom Content Blocks For fine-grained citation control, use custom content blocks: [source,java] ---- AnthropicCitationDocument document = AnthropicCitationDocument.builder() .customContent( "The Great Wall of China is approximately 21,196 kilometers long.", "It was built over many centuries, starting in the 7th century BC.", "The wall was constructed to protect Chinese states from invasions." ) .title("Great Wall Facts") .citationsEnabled(true) .build(); ---- === Using Citations in Requests Include citation documents in your chat options: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "When was the Eiffel Tower built and how tall is it?", AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .maxTokens(1024) .citationDocuments(document) .build() ) ); ---- ==== Multiple Documents You can provide multiple documents for Claude to reference: [source,java] ---- AnthropicCitationDocument parisDoc = AnthropicCitationDocument.builder() .plainText("Paris is the capital city of France with a population of 2.1 million.") .title("Paris Information") .citationsEnabled(true) .build(); AnthropicCitationDocument eiffelDoc = AnthropicCitationDocument.builder() .plainText("The Eiffel Tower was designed by Gustave Eiffel for the 1889 World's Fair.") .title("Eiffel Tower History") .citationsEnabled(true) .build(); ChatResponse response = chatModel.call( new Prompt( "What is the capital of France and who designed the Eiffel Tower?", AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .citationDocuments(parisDoc, eiffelDoc) .build() ) ); ---- === Accessing Citations Citations are returned in the response metadata: [source,java] ---- ChatResponse response = chatModel.call(prompt); // Get citations from metadata @SuppressWarnings("unchecked") List citations = (List) response.getMetadata().get("citations"); // Optional: Get citation count directly from metadata Integer citationCount = (Integer) response.getMetadata().get("citationCount"); System.out.println("Total citations: " + citationCount); // Process each citation for (Citation citation : citations) { System.out.println("Document: " + citation.getDocumentTitle()); System.out.println("Location: " + citation.getLocationDescription()); System.out.println("Cited text: " + citation.getCitedText()); System.out.println("Document index: " + citation.getDocumentIndex()); System.out.println(); } ---- === Citation Types Citations contain different location information depending on the document type: ==== Character Location (Plain Text) For plain text documents, citations include character indices: [source,java] ---- Citation citation = citations.get(0); if (citation.getType() == Citation.LocationType.CHAR_LOCATION) { int start = citation.getStartCharIndex(); int end = citation.getEndCharIndex(); String text = citation.getCitedText(); System.out.println("Characters " + start + "-" + end + ": " + text); } ---- ==== Page Location (PDF) For PDF documents, citations include page numbers: [source,java] ---- Citation citation = citations.get(0); if (citation.getType() == Citation.LocationType.PAGE_LOCATION) { int startPage = citation.getStartPageNumber(); int endPage = citation.getEndPageNumber(); System.out.println("Pages " + startPage + "-" + endPage); } ---- ==== Content Block Location (Custom Content) For custom content, citations reference specific content blocks: [source,java] ---- Citation citation = citations.get(0); if (citation.getType() == Citation.LocationType.CONTENT_BLOCK_LOCATION) { int startBlock = citation.getStartBlockIndex(); int endBlock = citation.getEndBlockIndex(); System.out.println("Content blocks " + startBlock + "-" + endBlock); } ---- === Complete Example Here's a complete example demonstrating citation usage: [source,java] ---- // Create a citation document AnthropicCitationDocument document = AnthropicCitationDocument.builder() .plainText("Spring AI is an application framework for AI engineering. " + "It provides a Spring-friendly API for developing AI applications. " + "The framework includes abstractions for chat models, embedding models, " + "and vector databases.") .title("Spring AI Overview") .citationsEnabled(true) .build(); // Call the model with the document ChatResponse response = chatModel.call( new Prompt( "What is Spring AI?", AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .maxTokens(1024) .citationDocuments(document) .build() ) ); // Display the response System.out.println("Response: " + response.getResult().getOutput().getText()); System.out.println("\nCitations:"); // Process citations List citations = (List) response.getMetadata().get("citations"); if (citations != null && !citations.isEmpty()) { for (int i = 0; i < citations.size(); i++) { Citation citation = citations.get(i); System.out.println("\n[" + (i + 1) + "] " + citation.getDocumentTitle()); System.out.println(" Location: " + citation.getLocationDescription()); System.out.println(" Text: " + citation.getCitedText()); } } else { System.out.println("No citations were provided in the response."); } ---- === Best Practices 1. **Use descriptive titles**: Provide meaningful titles for citation documents to help users identify sources in the citations. 2. **Check for null citations**: Not all responses will include citations, so always validate the citations metadata exists before accessing it. 3. **Consider document size**: Larger documents provide more context but consume more input tokens and may affect response time. 4. **Leverage multiple documents**: When answering questions that span multiple sources, provide all relevant documents in a single request rather than making multiple calls. 5. **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. === Citation Document Options ==== Context Field Optionally provide context about the document that won't be cited but can guide Claude's understanding: [source,java] ---- AnthropicCitationDocument document = AnthropicCitationDocument.builder() .plainText("...") .title("Legal Contract") .context("This is a merger agreement dated January 2024 between Company A and Company B") .build(); ---- ==== Controlling Citations By default, citations are disabled for all documents (opt-in behavior). To enable citations, explicitly set `citationsEnabled(true)`: [source,java] ---- AnthropicCitationDocument document = AnthropicCitationDocument.builder() .plainText("The Eiffel Tower was completed in 1889...") .title("Historical Facts") .citationsEnabled(true) // Explicitly enable citations for this document .build(); ---- You can also provide documents without citations for background context: [source,java] ---- AnthropicCitationDocument backgroundDoc = AnthropicCitationDocument.builder() .plainText("Background information about the industry...") .title("Context Document") // citationsEnabled defaults to false - Claude will use this but not cite it .build(); ---- [NOTE] ==== Anthropic requires consistent citation settings across all documents in a request. You cannot mix citation-enabled and citation-disabled documents in the same request. ==== == Prompt Caching Anthropic'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. === Caching Strategies Five caching strategies are available via `AnthropicCacheStrategy`: [cols="2,5", stripes=even] |==== | Strategy | Description | `NONE` | No caching (default). No cache control headers are added. | `SYSTEM_ONLY` | Cache system message content. Uses 1 cache breakpoint. | `TOOLS_ONLY` | Cache tool definitions only. Uses 1 cache breakpoint. | `SYSTEM_AND_TOOLS` | Cache both system messages and tool definitions. Uses 2 cache breakpoints. | `CONVERSATION_HISTORY` | Cache system messages, tool definitions, and conversation messages. Uses up to 4 cache breakpoints. |==== NOTE: 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. === Basic Usage [source,java] ---- var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .maxTokens(1024) .cacheOptions(AnthropicCacheOptions.builder() .strategy(AnthropicCacheStrategy.SYSTEM_ONLY) .build()) .build(); ChatResponse response = chatModel.call( new Prompt(List.of( new SystemMessage("You are an expert assistant with deep domain knowledge..."), new UserMessage("What is the capital of France?")), options)); ---- === Cache Configuration Options `AnthropicCacheOptions` provides fine-grained control over caching behavior: [source,java] ---- var cacheOptions = AnthropicCacheOptions.builder() .strategy(AnthropicCacheStrategy.SYSTEM_AND_TOOLS) .messageTypeTtl(MessageType.SYSTEM, AnthropicCacheTtl.ONE_HOUR) // 1 hour TTL .messageTypeMinContentLength(MessageType.SYSTEM, 100) // Min 100 chars .multiBlockSystemCaching(true) // Per-block caching .build(); ---- [cols="3,5,1", stripes=even] |==== | Option | Description | Default | `strategy` | The caching strategy to use. | `NONE` | `messageTypeTtl` | TTL per message type. Available values: `FIVE_MINUTES`, `ONE_HOUR`. | `FIVE_MINUTES` for all types | `messageTypeMinContentLength` | Minimum content length required before caching a message type. | `1` | `contentLengthFunction` | Custom function to compute content length (e.g., token counting). | `String::length` | `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` |==== === Multi-Block System Caching When you have both a static system prompt and dynamic instructions, use multi-block system caching to cache only the static portion: [source,java] ---- var cacheOptions = AnthropicCacheOptions.builder() .strategy(AnthropicCacheStrategy.SYSTEM_ONLY) .multiBlockSystemCaching(true) .build(); ChatResponse response = chatModel.call( new Prompt(List.of( new SystemMessage("You are an expert knowledge base assistant..."), // Static (cached) new SystemMessage("Today's date is 2025-02-23. User timezone: PST"), // Dynamic new UserMessage("What are the latest updates?")), AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .cacheOptions(cacheOptions) .build())); ---- === Accessing Cache Token Usage Cache token metrics are available through the native SDK `Usage` object: [source,java] ---- ChatResponse response = chatModel.call(prompt); com.anthropic.models.messages.Usage sdkUsage = (com.anthropic.models.messages.Usage) response.getMetadata().getUsage().getNativeUsage(); long cacheCreation = sdkUsage.cacheCreationInputTokens().orElse(0L); long cacheRead = sdkUsage.cacheReadInputTokens().orElse(0L); System.out.println("Cache creation tokens: " + cacheCreation); System.out.println("Cache read tokens: " + cacheRead); ---- On 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). === Conversation History Caching The `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: [source,java] ---- var cacheOptions = AnthropicCacheOptions.builder() .strategy(AnthropicCacheStrategy.CONVERSATION_HISTORY) .build(); var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .cacheOptions(cacheOptions) .build(); // First turn ChatResponse response1 = chatModel.call( new Prompt(List.of( new SystemMessage("You are a helpful assistant."), new UserMessage("What is machine learning?")), options)); // Second turn - previous context is cached ChatResponse response2 = chatModel.call( new Prompt(List.of( new SystemMessage("You are a helpful assistant."), new UserMessage("What is machine learning?"), new AssistantMessage(response1.getResult().getOutput().getText()), new UserMessage("Can you give me an example?")), options)); ---- == Structured Output Structured 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. [NOTE] ==== *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. *Schema Requirements* When using JSON schema output, Anthropic requires `"additionalProperties": false` for all object types in the schema. ==== === JSON Schema Output Constrain Claude's responses to a specific JSON schema using the `outputSchema` convenience method: [source,java] ---- var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .outputSchema(""" { "type": "object", "properties": { "name": {"type": "string"}, "capital": {"type": "string"}, "population": {"type": "integer"} }, "required": ["name", "capital"], "additionalProperties": false } """) .build(); ChatResponse response = chatModel.call(new Prompt("Tell me about France.", options)); // Response text will be valid JSON conforming to the schema ---- === Effort Control Control how much compute Claude spends on its response. Lower effort means faster, cheaper responses; higher effort means more thorough reasoning. [cols="2,5", stripes=even] |==== | Effort Level | Description | `LOW` | Fast and concise responses with minimal reasoning | `MEDIUM` | Balanced trade-off between speed and thoroughness | `HIGH` | More thorough reasoning and detailed responses | `MAX` | Maximum compute for the most thorough possible responses |==== [source,java] ---- var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .effort(OutputConfig.Effort.LOW) .build(); ChatResponse response = chatModel.call(new Prompt("What is the capital of France?", options)); ---- === Combined Schema and Effort You can combine JSON schema output with effort control: [source,java] ---- var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .outputSchema(""" { "type": "object", "properties": { "answer": {"type": "integer"}, "explanation": {"type": "string"} }, "required": ["answer", "explanation"], "additionalProperties": false } """) .effort(OutputConfig.Effort.HIGH) .build(); ChatResponse response = chatModel.call( new Prompt("What is 15 * 23? Show your reasoning.", options)); ---- === Direct OutputConfig For full control, use the SDK's `OutputConfig` directly: [source,java] ---- import com.anthropic.models.messages.OutputConfig; import com.anthropic.models.messages.JsonOutputFormat; import com.anthropic.core.JsonValue; var outputConfig = OutputConfig.builder() .effort(OutputConfig.Effort.HIGH) .format(JsonOutputFormat.builder() .schema(JsonOutputFormat.Schema.builder() .putAdditionalProperty("type", JsonValue.from("object")) .putAdditionalProperty("properties", JsonValue.from(Map.of( "name", Map.of("type", "string")))) .putAdditionalProperty("additionalProperties", JsonValue.from(false)) .build()) .build()) .build(); var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .outputConfig(outputConfig) .build(); ChatResponse response = chatModel.call(new Prompt("Tell me about France.", options)); ---- === StructuredOutputChatOptions Interface `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. == Service Tier Anthropic 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. Via Spring Boot properties: [source,properties] ---- spring.ai.anthropic.chat.options.service-tier=auto ---- Or programmatically per-request: [source,java] ---- var options = AnthropicChatOptions.builder() .serviceTier(AnthropicServiceTier.AUTO) .build(); ChatResponse response = chatModel.call(new Prompt("Hello", options)); ---- == Per-Request HTTP Headers The 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). Per-request headers are useful for: * **Request tracking**: Adding correlation IDs or trace headers per request * **Beta API access**: Including beta feature headers for specific requests * **Routing**: Adding routing or priority headers for load balancing [source,java] ---- var options = AnthropicChatOptions.builder() .httpHeaders(Map.of( "X-Request-Id", "req-12345", "X-Custom-Tracking", "my-tracking-value")) .build(); ChatResponse response = chatModel.call(new Prompt("Hello", options)); ---- NOTE: `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. == Sample Controller Here is an example of a simple `@RestController` class that uses the chat model for text generations: [source,java] ---- @RestController public class ChatController { private final AnthropicChatModel chatModel; public ChatController() { var options = AnthropicChatOptions.builder() .model("claude-sonnet-4-20250514") .maxTokens(1024) .apiKey(System.getenv("ANTHROPIC_API_KEY")) .build(); this.chatModel = new AnthropicChatModel(options); } @GetMapping("/ai/generate") public Map generate( @RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream( @RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return chatModel.stream(prompt); } } ---- == Accessing the Raw Response The 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: [source,java] ---- ChatResponse response = chatModel.call(new Prompt("Hello")); com.anthropic.models.messages.Message rawMessage = (com.anthropic.models.messages.Message) response.getMetadata().get("anthropic-response"); // Access native SDK fields rawMessage.stopReason(); // Optional rawMessage.content(); // List rawMessage.usage(); // Usage with cache token details ---- NOTE: The raw response is available for synchronous calls only. Streaming responses do not include it. == Skills Anthropic'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. Skills enable Claude to create actual downloadable files -- Excel spreadsheets, PowerPoint presentations, Word documents, and PDFs -- rather than just describing what these documents might contain. [NOTE] ==== *Supported Models* Skills are supported on Claude Sonnet 4, Claude Sonnet 4.5, Claude Opus 4, and later models. *Requirements* * Skills require the code execution capability (automatically enabled by Spring AI when skills are configured) * Maximum of 8 skills per request * Generated files are available for download via the Files API for 24 hours ==== === Pre-built Anthropic Skills Spring AI provides type-safe access to Anthropic's pre-built skills through the `AnthropicSkill` enum: [cols="2,3,4", stripes=even] |==== | Skill | Description | Generated File Type | `XLSX` | Excel spreadsheet generation and manipulation | `.xlsx` (Microsoft Excel) | `PPTX` | PowerPoint presentation creation | `.pptx` (Microsoft PowerPoint) | `DOCX` | Word document generation | `.docx` (Microsoft Word) | `PDF` | PDF document creation | `.pdf` (Portable Document Format) |==== === Basic Usage Enable skills by adding them to your `AnthropicChatOptions`: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Create an Excel spreadsheet with Q1 2025 sales data. " + "Include columns for Month, Revenue, and Expenses with 3 rows of sample data.", AnthropicChatOptions.builder() .model(Model.CLAUDE_SONNET_4_5) .maxTokens(4096) .skill(AnthropicSkill.XLSX) .build() ) ); // Claude will generate an actual Excel file String responseText = response.getResult().getOutput().getText(); System.out.println(responseText); // Output: "I've created an Excel spreadsheet with your Q1 2025 sales data..." ---- === Multiple Skills You can enable multiple skills in a single request (up to 8): [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Create a sales report with both an Excel file containing the raw data " + "and a PowerPoint presentation summarizing the key findings.", AnthropicChatOptions.builder() .model(Model.CLAUDE_SONNET_4_5) .maxTokens(8192) .skill(AnthropicSkill.XLSX) .skill(AnthropicSkill.PPTX) .build() ) ); ---- === Using AnthropicSkillContainer for Advanced Configuration For more control over skill types and versions, use `AnthropicSkillContainer` directly: [source,java] ---- AnthropicSkillContainer container = AnthropicSkillContainer.builder() .skill(AnthropicSkill.XLSX) .skill(AnthropicSkill.PPTX, "20251013") // Specific version .build(); ChatResponse response = chatModel.call( new Prompt( "Generate the quarterly report", AnthropicChatOptions.builder() .model(Model.CLAUDE_SONNET_4_5) .maxTokens(4096) .skillContainer(container) .build() ) ); ---- === Downloading Generated Files When Claude generates files using Skills, the response contains file IDs that can be used to download the actual files via the Files API. Spring AI provides the `AnthropicSkillsResponseHelper` utility class for extracting file IDs and downloading files. ==== Extracting File IDs [source,java] ---- import org.springframework.ai.anthropic.AnthropicSkillsResponseHelper; ChatResponse response = chatModel.call(prompt); // Extract all file IDs from the response List fileIds = AnthropicSkillsResponseHelper.extractFileIds(response); for (String fileId : fileIds) { System.out.println("Generated file ID: " + fileId); } ---- ==== Downloading All Files The `AnthropicSkillsResponseHelper` provides a convenience method to download all generated files at once. This requires the `AnthropicClient` instance (the same one used to create the chat model): [source,java] ---- import com.anthropic.client.AnthropicClient; @Autowired private AnthropicClient anthropicClient; // Download all files to a target directory Path targetDir = Path.of("generated-files"); Files.createDirectories(targetDir); List savedFiles = AnthropicSkillsResponseHelper.downloadAllFiles( response, anthropicClient, targetDir); for (Path file : savedFiles) { System.out.println("Downloaded: " + file.getFileName() + " (" + Files.size(file) + " bytes)"); } ---- ==== Extracting Container ID For multi-turn conversations with Skills, you can extract the container ID for reuse: [source,java] ---- String containerId = AnthropicSkillsResponseHelper.extractContainerId(response); if (containerId != null) { System.out.println("Container ID for reuse: " + containerId); } ---- === Complete Example Here's a complete example showing Skills usage with file download: [source,java] ---- @Service public class DocumentGenerationService { private final AnthropicChatModel chatModel; private final AnthropicClient anthropicClient; public DocumentGenerationService(AnthropicChatModel chatModel, AnthropicClient anthropicClient) { this.chatModel = chatModel; this.anthropicClient = anthropicClient; } public Path generateSalesReport(String quarter, Path outputDir) throws IOException { // Generate Excel report using Skills ChatResponse response = chatModel.call( new Prompt( "Create an Excel spreadsheet with " + quarter + " sales data. " + "Include Month, Revenue, Expenses, and Profit columns.", AnthropicChatOptions.builder() .model(Model.CLAUDE_SONNET_4_5) .maxTokens(4096) .skill(AnthropicSkill.XLSX) .build() ) ); // Extract file IDs from the response List fileIds = AnthropicSkillsResponseHelper.extractFileIds(response); if (fileIds.isEmpty()) { throw new RuntimeException("No file was generated"); } // Download all generated files List savedFiles = AnthropicSkillsResponseHelper.downloadAllFiles( response, anthropicClient, outputDir); return savedFiles.get(0); } } ---- === Best Practices 1. **Use appropriate models**: Skills work best with Claude Sonnet 4 and later models. Ensure you're using a supported model. 2. **Set sufficient max tokens**: Document generation can require significant tokens. Use `maxTokens(4096)` or higher for complex documents. 3. **Be specific in prompts**: Provide clear, detailed instructions about document structure, content, and formatting. 4. **Handle file downloads promptly**: Generated files expire after 24 hours. Download files soon after generation. 5. **Check for file IDs**: Always verify that file IDs were returned before attempting downloads. Some prompts may result in text responses without file generation. 6. **Use defensive error handling**: Wrap file operations in try-catch blocks to handle network issues or expired files gracefully.

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]. Azure 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. == Prerequisites The Azure OpenAI client offers three options to connect: using an Azure API key or using an OpenAI API Key, or using Microsoft Entra ID. === Azure API Key & Endpoint To 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]. Spring AI defines two configuration properties: 1. `spring.ai.azure.openai.api-key`: Set this to the value of the `API Key` obtained from Azure. 2. `spring.ai.azure.openai.endpoint`: Set this to the endpoint URL obtained when provisioning your model in Azure. You can set these configuration properties in your `application.properties` or `application.yml` file: [source,properties] ---- spring.ai.azure.openai.api-key= spring.ai.azure.openai.endpoint= ---- For enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference custom environment variables: [source,yaml] ---- # In application.yml spring: ai: azure: openai: api-key: ${AZURE_OPENAI_API_KEY} endpoint: ${AZURE_OPENAI_ENDPOINT} ---- [source,bash] ---- # In your environment or .env file export AZURE_OPENAI_API_KEY= export AZURE_OPENAI_ENDPOINT= ---- === OpenAI Key To authenticate with the OpenAI service (not Azure), provide an OpenAI API key. This will automatically set the endpoint to https://api.openai.com/v1. When 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. In your application configuration: [source,properties] ---- spring.ai.azure.openai.openai-api-key= spring.ai.azure.openai.chat.options.deployment-name= ---- Using environment variables with SpEL: [source,yaml] ---- # In application.yml spring: ai: azure: openai: openai-api-key: ${AZURE_OPENAI_API_KEY} chat: options: deployment-name: ${AZURE_OPENAI_MODEL_NAME} ---- [source,bash] ---- # In your environment or .env file export AZURE_OPENAI_API_KEY= export AZURE_OPENAI_MODEL_NAME= ---- === Microsoft Entra ID For 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. Finding 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. NOTE: It is no longer necessary to create a `TokenCredential` bean; it is configured for you automatically. === Deployment Name To use Azure AI applications, you need to create an Azure AI Deployment through the link:https://oai.azure.com/portal[Azure AI Portal]. In Azure, each client must specify a `Deployment Name` to connect to the Azure OpenAI service. It's important to note that the `Deployment Name` is different from the model you choose to deploy. For example, a deployment named 'MyAiDeployment' could be configured to use either the GPT 3.5 Turbo model or the GPT 4.0 model. To get started, follow these steps to create a deployment with the default settings: Deployment Name: `gpt-4o` Model Name: `gpt-4o` This Azure configuration aligns with the default configurations of the Spring Boot Azure AI Starter and its Autoconfiguration feature. If you use a different Deployment Name, make sure to update the configuration property accordingly: ``` spring.ai.azure.openai.chat.options.deployment-name= ``` The different deployment structures of Azure OpenAI and OpenAI leads to a property in the Azure OpenAI client library named `deploymentOrModelName`. This is because in OpenAI there is no `Deployment Name`, only a `Model Name`. NOTE: The property `spring.ai.azure.openai.chat.options.model` has been renamed to `spring.ai.azure.openai.chat.options.deployment-name`. NOTE: If you decide to connect to `OpenAI` instead of `Azure OpenAI`, by setting the `spring.ai.azure.openai.openai-api-key=` property, then the `spring.ai.azure.openai.chat.options.deployment-name` is treated as an link:https://platform.openai.com/docs/models[OpenAI model] name. ==== Access the OpenAI Model You can configure the client to use directly `OpenAI` instead of the `Azure OpenAI` deployed models. For this you need to set the `spring.ai.azure.openai.openai-api-key=` instead of `spring.ai.azure.openai.api-key=`. === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the Azure OpenAI Chat Client. To enable it add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-azure-openai ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-azure-openai' } ---- ====== TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. The 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. A customizer might be used for example to change the default response timeout: [source,java] ---- @Configuration public class AzureOpenAiConfig { @Bean public AzureOpenAIClientBuilderCustomizer responseTimeoutCustomizer() { return openAiClientBuilder -> { HttpClientOptions clientOptions = new HttpClientOptions() .setResponseTimeout(Duration.ofMinutes(5)); openAiClientBuilder.httpClient(HttpClient.createDefault(clientOptions)); }; } } ---- === Chat Properties The prefix `spring.ai.azure.openai` is the property prefix to configure the connection to Azure OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.azure.openai.api-key | The Key from Azure AI OpenAI `Keys and Endpoint` section under `Resource Management` | - | spring.ai.azure.openai.endpoint | The endpoint from the Azure AI OpenAI `Keys and Endpoint` section under `Resource Management` | - | spring.ai.azure.openai.openai-api-key | (non Azure) OpenAI API key. Used to authenticate with the OpenAI service, instead of Azure OpenAI. This automatically sets the endpoint to https://api.openai.com/v1. Use either `api-key` or `openai-api-key` property. With this configuration the `spring.ai.azure.openai.chat.options.deployment-name` is treated as an https://platform.openai.com/docs/models[OpenAi Model] name.| - | 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 |==== [NOTE] ==== Enabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`. To enable, spring.ai.model.chat=azure-openai (It is enabled by default) To disable, spring.ai.model.chat=none (or any value which doesn't match azure-openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.azure.openai.chat` is the property prefix that configures the `ChatModel` implementation for Azure OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.azure.openai.chat.enabled (Removed and no longer valid) | Enable Azure OpenAI chat model. | true | spring.ai.model.chat | Enable Azure OpenAI chat model. | azure-openai | 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. It's important to note that within an Azure OpenAI deployment, the "Deployment Name" is distinct from the model itself. The confusion around these terms stems from the intention to make the Azure OpenAI client library compatible with the original OpenAI endpoint. The deployment structures offered by Azure OpenAI and Sam Altman's OpenAI differ significantly. Deployments model name to provide as part of this completions request. | gpt-4o | 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.* | - | 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.* | - | 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. | - | 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. | - | 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. | - | 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. | - | 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 | spring.ai.azure.openai.chat.options.n | The number of chat completions choices that should be generated for a chat completions response. | - | spring.ai.azure.openai.chat.options.stop | A collection of textual sequences that will end completions generation. | - | 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. | - | 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`. The `JSON_OBJECT` type enables JSON mode, which guarantees the message the model generates is valid JSON. The `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. | - | spring.ai.azure.openai.chat.options.responseFormat.schema | Response format JSON schema. Applicable only for `responseFormat.type=JSON_SCHEMA` | - | 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. | - | 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. | - | spring.ai.azure.openai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | - | 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 |==== TIP: All properties prefixed with `spring.ai.azure.openai.chat.options` can be overridden at runtime by adding a request specific <> to the `Prompt` call. === Token Limit Parameters: Model-Specific Usage Azure OpenAI has model-specific requirements for token limiting parameters: [cols="1,1,2", options="header"] |==== | Model Family | Required Parameter | Notes | **Reasoning Models** + (o1, o3, o4-mini series) | `maxCompletionTokens` | These models only accept `maxCompletionTokens`. Using `maxTokens` will result in an API error. | **Non-Reasoning Models** + (gpt-4o, gpt-3.5-turbo, etc.) | `maxTokens` | Traditional models use `maxTokens` for output limiting. Using `maxCompletionTokens` may result in an API error. |==== IMPORTANT: 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. .Example: Using maxCompletionTokens for reasoning models [source,java] ---- var options = AzureOpenAiChatOptions.builder() .deploymentName("o1-preview") .maxCompletionTokens(500) // Required for reasoning models .build(); ---- .Example: Using maxTokens for non-reasoning models [source,java] ---- var options = AzureOpenAiChatOptions.builder() .deploymentName("gpt-4o") .maxTokens(500) // Required for non-reasoning models .build(); ---- == Runtime Options [[chat-options]] The 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. On start-up, the default options can be configured with the `AzureOpenAiChatModel(api, options)` constructor or the `spring.ai.azure.openai.chat.options.*` properties. At runtime you can override the default options by adding new, request specific, options to the `Prompt` call. For example to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", AzureOpenAiChatOptions.builder() .deploymentName("gpt-4o") .temperature(0.4) .build() )); ---- TIP: 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()]. == Function Calling You 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. This is a powerful technique to connect the LLM capabilities with external tools and APIs. Read more about xref:api/tools.adoc[Tool Calling]. == Multimodal Multimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats. Presently, the Azure OpenAI `gpt-4o` model offers multimodal support. The Azure OpenAI can incorporate a list of base64-encoded images or image urls with the message. Spring 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. This 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. Below 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. [source,java] ---- URL url = new URL("https://docs.spring.io/spring-ai/reference/_images/multimodal.test.png"); String response = ChatClient.create(chatModel).prompt() .options(AzureOpenAiChatOptions.builder().deploymentName("gpt-4o").build()) .user(u -> u.text("Explain what do you see on this picture?").media(MimeTypeUtils.IMAGE_PNG, this.url)) .call() .content(); ---- TIP: you can pass multiple images as well. It takes as an input the `multimodal.test.png` image: image::multimodal.test.png[Multimodal Test Image, 200, 200, align="left"] along with the text message "Explain what do you see on this picture?", and generates a response like this: ---- This is an image of a fruit bowl with a simple design. The bowl is made of metal with curved wire edges that create an open structure, allowing the fruit to be visible from all angles. Inside the bowl, there are two yellow bananas resting on top of what appears to be a red apple. The bananas are slightly overripe, as indicated by the brown spots on their peels. The bowl has a metal ring at the top, likely to serve as a handle for carrying. The bowl is placed on a flat surface with a neutral-colored background that provides a clear view of the fruit inside. ---- You can also pass in a classpath resource instead of a URL as shown in the example below [source,java] ---- Resource resource = new ClassPathResource("multimodality/multimodal.test.png"); String response = ChatClient.create(chatModel).prompt() .options(AzureOpenAiChatOptions.builder() .deploymentName("gpt-4o").build()) .user(u -> u.text("Explain what do you see on this picture?") .media(MimeTypeUtils.IMAGE_PNG, this.resource)) .call() .content(); ---- == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-azure-openai` to your pom (or gradle) dependencies. Add a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model: [source,application.properties] ---- spring.ai.azure.openai.api-key=YOUR_API_KEY spring.ai.azure.openai.endpoint=YOUR_ENDPOINT spring.ai.azure.openai.chat.options.deployment-name=gpt-4o spring.ai.azure.openai.chat.options.temperature=0.7 ---- TIP: replace the `api-key` and `endpoint` with your Azure OpenAI credentials. This will create a `AzureOpenAiChatModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the chat model for text generations. [source,java] ---- @RestController public class ChatController { private final AzureOpenAiChatModel chatModel; @Autowired public ChatController(AzureOpenAiChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- == Manual Configuration The 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]. To enable it, add the `spring-ai-azure-openai` dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-azure-openai ---- or to your Gradle `build.gradle` build file. [source,gradle] ---- dependencies { implementation 'org.springframework.ai:spring-ai-azure-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. TIP: 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. Next, create an `AzureOpenAiChatModel` instance and use it to generate text responses: [source,java] ---- var openAIClientBuilder = new OpenAIClientBuilder() .credential(new AzureKeyCredential(System.getenv("AZURE_OPENAI_API_KEY"))) .endpoint(System.getenv("AZURE_OPENAI_ENDPOINT")); var openAIChatOptions = AzureOpenAiChatOptions.builder() .deploymentName("gpt-5") .temperature(0.4) .maxCompletionTokens(200) .build(); var chatModel = AzureOpenAiChatModel.builder() .openAIClientBuilder(openAIClientBuilder) .defaultOptions(openAIChatOptions) .build(); ChatResponse response = chatModel.call( new Prompt("Generate the names of 5 famous pirates.")); // Or with streaming responses Flux streamingResponses = chatModel.stream( new Prompt("Generate the names of 5 famous pirates.")); ---- NOTE: the `gpt-4o` is actually the `Deployment Name` as presented in the Azure AI Portal. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chat/bedrock-converse.adoc ================================================ = Bedrock Converse API link:https://docs.aws.amazon.com/bedrock/latest/userguide/conversation-inference.html[Amazon Bedrock Converse API] provides a unified interface for conversational AI models with enhanced capabilities including function/tool calling, multimodal inputs, and streaming responses. The Bedrock Converse API has the following high-level features: * Tool/Function Calling: Support for function definitions and tool use during conversations * Multimodal Input: Ability to process both text and image inputs in conversations * Streaming Support: Real-time streaming of model responses * System Messages: Support for system-level instructions and context setting TIP: The Bedrock Converse API provides a unified interface across multiple model providers while handling AWS-specific authentication and infrastructure concerns. Currently, the Converse API link:https://docs.aws.amazon.com/bedrock/latest/userguide/conversation-inference-supported-models-features.html[Supported Models] include: `Amazon Titan`, `Amazon Nova`, `AI21 Labs`, `Anthropic Claude`, `Cohere Command`, `Meta Llama`, `Mistral AI`. [NOTE] ==== Following the Bedrock recommendations, Spring AI is transitioning to using Amazon Bedrock's Converse API for all chat conversation implementations in Spring AI. While the existing xref:api/bedrock-chat.adoc[InvokeModel API] supports conversation applications, we strongly recommend adopting the Converse API for all Chat conversation models. The Converse API does not support embedding operations, so these will remain in the current API and the embedding model functionality in the existing `InvokeModel API` will be maintained ==== == Prerequisites Refer to https://docs.aws.amazon.com/bedrock/latest/userguide/getting-started.html[Getting started with Amazon Bedrock] for setting up API access * Obtain AWS credentials: If you don't have an AWS account and AWS CLI configured yet, this video guide can help you configure it: link:https://youtu.be/gswVHTrRX8I?si=buaY7aeI0l3-bBVb[AWS CLI & SDK Setup in Less Than 4 Minutes!].

At run-time you can override the default options by adding new, request specific, options to the `Prompt` call: [source,java] ---- var options = BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .temperature(0.6) .maxTokens(300) .toolCallbacks(List.of(FunctionToolCallback.builder("getCurrentWeather", new WeatherService()) .description("Get the weather in location. Return temperature in 36°F or 36°C format. Use multi-turn if needed.") .inputType(WeatherService.Request.class) .build())) .build(); String response = ChatClient.create(this.chatModel) .prompt("What is current weather in Amsterdam?") .options(options) .call() .content(); ---- == Prompt Caching AWS 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. When you cache a prompt, subsequent identical requests can reuse the cached content, significantly reducing the number of input tokens processed. [NOTE] ==== *Supported Models* Prompt caching is supported on Claude 3.x, Claude 4.x, and Amazon Nova models available through AWS Bedrock. *Token Requirements* Different models have different minimum token thresholds for cache effectiveness: - Claude Sonnet 4 and most models: 1024+ tokens - Model-specific requirements may vary - consult AWS Bedrock documentation ==== === Cache Strategies Spring AI provides strategic cache placement through the `BedrockCacheStrategy` enum: * `NONE`: Disables prompt caching completely (default) * `SYSTEM_ONLY`: Caches only the system message content * `TOOLS_ONLY`: Caches tool definitions only (Claude models only) * `SYSTEM_AND_TOOLS`: Caches both system message and tool definitions (Claude models only) * `CONVERSATION_HISTORY`: Caches entire conversation history in chat memory scenarios This strategic approach ensures optimal cache breakpoint placement while staying within AWS Bedrock's 4-breakpoint limit. [NOTE] ==== *Amazon Nova Limitations* Amazon Nova models (Nova Micro, Lite, Pro, Premier) only support caching for `system` and `messages` content. They do **not** support caching for `tools`. If you attempt to use `TOOLS_ONLY` or `SYSTEM_AND_TOOLS` strategies with Nova models, AWS will return a `ValidationException`. Use `SYSTEM_ONLY` strategy for Amazon Nova models. ==== === Enabling Prompt Caching Enable prompt caching by setting `cacheOptions` on `BedrockChatOptions` and choosing a `strategy`. ==== System-Only Caching The most common use case - cache system instructions across multiple requests: [source,java] ---- // Cache system message content ChatResponse response = chatModel.call( new Prompt( List.of( new SystemMessage("You are a helpful AI assistant with extensive knowledge..."), new UserMessage("What is machine learning?") ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_ONLY) .build()) .maxTokens(500) .build() ) ); ---- ==== Tools-Only Caching Cache large tool definitions while keeping system prompts dynamic (Claude models only): [source,java] ---- // Cache tool definitions only ChatResponse response = chatModel.call( new Prompt( "What's the weather in San Francisco?", BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.TOOLS_ONLY) .build()) .toolCallbacks(weatherToolCallbacks) // Large tool definitions .maxTokens(500) .build() ) ); ---- NOTE: This strategy is only supported on Claude models. Amazon Nova models will return a `ValidationException`. ==== System and Tools Caching Cache both system instructions and tool definitions for maximum reuse (Claude models only): [source,java] ---- // Cache system message and tool definitions ChatResponse response = chatModel.call( new Prompt( List.of( new SystemMessage("You are a weather analysis assistant..."), new UserMessage("What's the weather like in Tokyo?") ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_AND_TOOLS) .build()) .toolCallbacks(weatherToolCallbacks) .maxTokens(500) .build() ) ); ---- NOTE: This strategy uses 2 cache breakpoints (one for tools, one for system). Only supported on Claude models. ==== Conversation History Caching Cache growing conversation history for multi-turn chatbots and assistants: [source,java] ---- // Cache conversation history with ChatClient and memory ChatClient chatClient = ChatClient.builder(chatModel) .defaultSystem("You are a personalized career counselor...") .defaultAdvisors(MessageChatMemoryAdvisor.builder(chatMemory) .conversationId(conversationId) .build()) .build(); String response = chatClient.prompt() .user("What career advice would you give me?") .options(BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.CONVERSATION_HISTORY) .build()) .maxTokens(500) .build()) .call() .content(); ---- ==== Using ChatClient Fluent API [source,java] ---- String response = ChatClient.create(chatModel) .prompt() .system("You are an expert document analyst...") .user("Analyze this large document: " + document) .options(BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_ONLY) .build()) .build()) .call() .content(); ---- === Usage Example Here's a complete example demonstrating prompt caching with cost tracking: [source,java] ---- // Create system content that will be reused multiple times String largeSystemPrompt = "You are an expert software architect specializing in distributed systems..."; // (Ensure this is 1024+ tokens for cache effectiveness) // First request - creates cache ChatResponse firstResponse = chatModel.call( new Prompt( List.of( new SystemMessage(largeSystemPrompt), new UserMessage("What is microservices architecture?") ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_ONLY) .build()) .maxTokens(500) .build() ) ); // Access cache-related token usage from metadata Integer cacheWrite1 = (Integer) firstResponse.getMetadata() .getMetadata() .get("cacheWriteInputTokens"); Integer cacheRead1 = (Integer) firstResponse.getMetadata() .getMetadata() .get("cacheReadInputTokens"); System.out.println("Cache creation tokens: " + cacheWrite1); System.out.println("Cache read tokens: " + cacheRead1); // Second request with same system prompt - reads from cache ChatResponse secondResponse = chatModel.call( new Prompt( List.of( new SystemMessage(largeSystemPrompt), // Same prompt - cache hit new UserMessage("What are the benefits of event sourcing?") ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_ONLY) .build()) .maxTokens(500) .build() ) ); Integer cacheWrite2 = (Integer) secondResponse.getMetadata() .getMetadata() .get("cacheWriteInputTokens"); Integer cacheRead2 = (Integer) secondResponse.getMetadata() .getMetadata() .get("cacheReadInputTokens"); System.out.println("Cache creation tokens: " + cacheWrite2); // Should be 0 System.out.println("Cache read tokens: " + cacheRead2); // Should be > 0 ---- === Token Usage Tracking AWS Bedrock provides cache-specific metrics through the response. Cache metrics are accessible via two methods: ==== Native Usage Object (Recommended for Observability) For observability handlers and metrics collection, access cache metrics through the native `TokenUsage` object: [source,java] ---- import software.amazon.awssdk.services.bedrockruntime.model.TokenUsage; ChatResponse response = chatModel.call(/* ... */); // Access cache metrics from native TokenUsage object TokenUsage tokenUsage = (TokenUsage) response.getMetadata() .getUsage() .getNativeUsage(); if (tokenUsage != null) { Integer cacheWrite = tokenUsage.cacheWriteInputTokens(); Integer cacheRead = tokenUsage.cacheReadInputTokens(); System.out.println("Cache write: " + cacheWrite + ", Cache read: " + cacheRead); } ---- ==== Metadata Map (Backward Compatible) Cache metrics are also available via the metadata Map for backward compatibility: [source,java] ---- ChatResponse response = chatModel.call(/* ... */); // Access cache metrics from metadata Map Integer cacheWrite = (Integer) response.getMetadata() .getMetadata() .get("cacheWriteInputTokens"); Integer cacheRead = (Integer) response.getMetadata() .getMetadata() .get("cacheReadInputTokens"); ---- Cache-specific metrics include: * `cacheWriteInputTokens`: Returns the number of tokens used when creating a cache entry * `cacheReadInputTokens`: Returns the number of tokens read from an existing cache entry When you first send a cached prompt: - `cacheWriteInputTokens` will be greater than 0 - `cacheReadInputTokens` will be 0 When you send the same cached prompt again (within 5-minute TTL): - `cacheWriteInputTokens` will be 0 - `cacheReadInputTokens` will be greater than 0 === Real-World Use Cases ==== Legal Document Analysis Analyze large legal contracts or compliance documents efficiently by caching document content across multiple questions: [source,java] ---- // Load a legal contract (PDF or text) String legalContract = loadDocument("merger-agreement.pdf"); // ~3000 tokens // System prompt with legal expertise String legalSystemPrompt = "You are an expert legal analyst specializing in corporate law. " + "Analyze the following contract and provide precise answers about terms, obligations, and risks: " + legalContract; // First analysis - creates cache ChatResponse riskAnalysis = chatModel.call( new Prompt( List.of( new SystemMessage(legalSystemPrompt), new UserMessage("What are the key termination clauses and associated penalties?") ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_ONLY) .build()) .maxTokens(1000) .build() ) ); // Subsequent questions reuse cached document - 90% cost savings ChatResponse obligationAnalysis = chatModel.call( new Prompt( List.of( new SystemMessage(legalSystemPrompt), // Same content - cache hit new UserMessage("List all financial obligations and payment schedules.") ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_ONLY) .build()) .maxTokens(1000) .build() ) ); ---- ==== Batch Code Review Process multiple code files with consistent review criteria while caching the review guidelines: [source,java] ---- // Define comprehensive code review guidelines String reviewGuidelines = """ You are a senior software engineer conducting code reviews. Apply these criteria: - Security vulnerabilities and best practices - Performance optimizations and memory usage - Code maintainability and readability - Testing coverage and edge cases - Design patterns and architecture compliance """; List codeFiles = Arrays.asList( "UserService.java", "PaymentController.java", "SecurityConfig.java" ); List reviews = new ArrayList<>(); for (String filename : codeFiles) { String sourceCode = loadSourceFile(filename); ChatResponse review = chatModel.call( new Prompt( List.of( new SystemMessage(reviewGuidelines), // Cached across all reviews new UserMessage("Review this " + filename + " code:\n\n" + sourceCode) ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_ONLY) .build()) .maxTokens(800) .build() ) ); reviews.add(review.getResult().getOutput().getText()); } // Guidelines cached after first request, subsequent reviews are faster and cheaper ---- ==== Customer Support with Knowledge Base Create a customer support system that caches your product knowledge base for consistent, accurate responses: [source,java] ---- // Load comprehensive product knowledge String knowledgeBase = """ PRODUCT DOCUMENTATION: - API endpoints and authentication methods - Common troubleshooting procedures - Billing and subscription details - Integration guides and examples - Known issues and workarounds """ + loadProductDocs(); // ~2500 tokens @Service public class CustomerSupportService { public String handleCustomerQuery(String customerQuery, String customerId) { ChatResponse response = chatModel.call( new Prompt( List.of( new SystemMessage("You are a helpful customer support agent. " + "Use this knowledge base to provide accurate solutions: " + knowledgeBase), new UserMessage("Customer " + customerId + " asks: " + customerQuery) ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_ONLY) .build()) .maxTokens(600) .build() ) ); return response.getResult().getOutput().getText(); } } // Knowledge base is cached across all customer queries // Multiple support agents can benefit from the same cached content ---- ==== Multi-Tenant SaaS Application Cache shared tool definitions across different tenants while customizing system prompts per tenant: [source,java] ---- // Shared tool definitions (cached once, used across all tenants) List sharedTools = createLargeToolRegistry(); // ~2000 tokens // Tenant-specific configuration @Service public class MultiTenantAIService { public String processRequest(String tenantId, String userQuery) { // Load tenant-specific system prompt (changes per tenant) String tenantPrompt = loadTenantSystemPrompt(tenantId); ChatResponse response = chatModel.call( new Prompt( List.of( new SystemMessage(tenantPrompt), // Tenant-specific, not cached new UserMessage(userQuery) ), BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.TOOLS_ONLY) .build()) .toolCallbacks(sharedTools) // Shared tools - cached .maxTokens(500) .build() ) ); return response.getResult().getOutput().getText(); } } // Tools cached once, each tenant gets customized system prompt ---- === Best Practices 1. **Choose the Right Strategy**: - Use `SYSTEM_ONLY` for reusable system prompts and instructions (works with all models) - Use `TOOLS_ONLY` when you have large stable tools but dynamic system prompts (Claude only) - Use `SYSTEM_AND_TOOLS` when both system and tools are large and stable (Claude only) - Use `CONVERSATION_HISTORY` with ChatClient memory for multi-turn conversations - Use `NONE` to explicitly disable caching 2. **Meet Token Requirements**: Focus on caching content that meets the minimum token requirements (1024+ tokens for most models). 3. **Reuse Identical Content**: Caching works best with exact matches of prompt content. Even small changes will require a new cache entry. 4. **Monitor Token Usage**: Track cache effectiveness using the metadata metrics: Integer cacheWrite = (Integer) response.getMetadata().getMetadata().get("cacheWriteInputTokens"); Integer cacheRead = (Integer) response.getMetadata().getMetadata().get("cacheReadInputTokens"); if (cacheRead != null && cacheRead > 0) { System.out.println("Cache hit: " + cacheRead + " tokens saved"); } 5. **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. 6. **Cache Lifetime**: AWS Bedrock caches have a fixed 5-minute TTL (Time To Live). Each cache access resets the timer. 7. **Model Compatibility**: Be aware of model-specific limitations: - **Claude models**: Support all caching strategies - **Amazon Nova models**: Only support `SYSTEM_ONLY` and `CONVERSATION_HISTORY` (tool caching not supported) 8. **Tool Stability**: When using `TOOLS_ONLY`, `SYSTEM_AND_TOOLS`, or `CONVERSATION_HISTORY` strategies, ensure tools remain stable. Changing tool definitions will invalidate all downstream cache breakpoints due to cascade invalidation. === Cache Invalidation and Cascade Behavior AWS Bedrock follows a hierarchical cache model with cascade invalidation: **Cache Hierarchy**: `Tools → System → Messages` Changes at each level invalidate that level and all subsequent levels: [cols="1,1,1,1", stripes=even] |==== | What Changes | Tools Cache | System Cache | Messages Cache | Tools | ❌ Invalid | ❌ Invalid | ❌ Invalid | System | ✅ Valid | ❌ Invalid | ❌ Invalid | Messages | ✅ Valid | ✅ Valid | ❌ Invalid |==== **Example with `SYSTEM_AND_TOOLS` strategy**: [source,java] ---- // Request 1: Cache both tools and system ChatResponse r1 = chatModel.call( new Prompt( List.of(new SystemMessage("System prompt"), new UserMessage("Question")), BedrockChatOptions.builder() .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_AND_TOOLS) .build()) .toolCallbacks(tools) .build() ) ); // Result: Both caches created // Request 2: Change only system prompt (tools same) ChatResponse r2 = chatModel.call( new Prompt( List.of(new SystemMessage("DIFFERENT system prompt"), new UserMessage("Question")), BedrockChatOptions.builder() .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_AND_TOOLS) .build()) .toolCallbacks(tools) // SAME tools .build() ) ); // Result: Tools cache HIT (reused), system cache MISS (recreated) // Request 3: Change tools (system same as Request 2) ChatResponse r3 = chatModel.call( new Prompt( List.of(new SystemMessage("DIFFERENT system prompt"), new UserMessage("Question")), BedrockChatOptions.builder() .cacheOptions(BedrockCacheOptions.builder() .strategy(BedrockCacheStrategy.SYSTEM_AND_TOOLS) .build()) .toolCallbacks(newTools) // DIFFERENT tools .build() ) ); // Result: BOTH caches MISS (tools change invalidates everything downstream) ---- === Implementation Details The prompt caching implementation in Spring AI follows these key design principles: 1. **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. 2. **Provider Portability**: Cache configuration is done through `BedrockChatOptions` rather than individual messages, preserving compatibility when switching between different AI providers. 3. **Thread Safety**: The cache breakpoint tracking is implemented with thread-safe mechanisms to handle concurrent requests correctly. 4. **UNION Type Pattern**: AWS SDK uses UNION types where cache points are added as separate blocks rather than properties. This is different from direct API approaches but ensures type safety and API compliance. 5. **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. === Cost Considerations AWS Bedrock pricing for prompt caching (approximate, varies by model): * **Cache writes**: ~25% more expensive than base input tokens * **Cache reads**: ~90% cheaper (only 10% of base input token price) * **Break-even point**: After just 1 cache read, you've saved money **Example cost calculation**: [source,java] ---- // System prompt: 2000 tokens // User question: 50 tokens // Without caching (5 requests): // Cost: 5 × (2000 + 50) = 10,250 tokens at base rate // With caching (5 requests): // Request 1: 2000 tokens × 1.25 (cache write) + 50 = 2,550 tokens // Requests 2-5: 4 × (2000 × 0.10 (cache read) + 50) = 4 × 250 = 1,000 tokens // Total: 2,550 + 1,000 = 3,550 tokens equivalent // Savings: (10,250 - 3,550) / 10,250 = 65% cost reduction ---- == Tool Calling The Bedrock Converse API supports tool calling capabilities, allowing models to use tools during conversations. Here's an example of how to define and use @Tool based tools: [source,java] ---- public class WeatherService { @Tool(description = "Get the weather in location") public String weatherByLocation(@ToolParam(description= "City or state name") String location) { ... } } String response = ChatClient.create(this.chatModel) .prompt("What's the weather like in Boston?") .tools(new WeatherService()) .call() .content(); ---- You can use the java.util.function beans as tools as well: [source,java] ---- @Bean @Description("Get the weather in location. Return temperature in 36°F or 36°C format.") public Function weatherFunction() { return new MockWeatherService(); } String response = ChatClient.create(this.chatModel) .prompt("What's the weather like in Boston?") .toolNames("weatherFunction") .inputType(Request.class) .call() .content(); ---- Find more in xref:api/tools.adoc[Tools] documentation. == Structured Output [[structured-output]] AWS Bedrock supports native structured outputs through JSON Schema, ensuring the model generates responses that strictly conform to your specified structure. This 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. === Using ChatClient with Native Structured Output The simplest way to use structured output is with the `ChatClient` high-level API and the `ENABLE_NATIVE_STRUCTURED_OUTPUT` advisor: [source,java] ---- record ActorsFilms(String actor, List movies) {} ActorsFilms actorsFilms = ChatClient.create(chatModel).prompt() .options(ToolCallingChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .build()) .advisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT) .user("Generate the filmography for a random actor.") .call() .entity(ActorsFilms.class); ---- This approach automatically: - Generates a JSON schema from your Java class - Sets the `outputSchema` on `BedrockChatOptions` via the AWS Bedrock `OutputConfig` API - Parses the JSON response into your specified type === Using outputSchema Directly For more control, you can set the JSON schema directly on `BedrockChatOptions`: [source,java] ---- String jsonSchema = """ { "type": "object", "properties": { "actor": { "type": "string" }, "movies": { "type": "array", "items": { "type": "string" } } }, "required": ["actor", "movies"], "additionalProperties": false } """; ChatResponse response = chatModel.call( new Prompt("Generate the filmography for a random actor.", BedrockChatOptions.builder() .model("us.anthropic.claude-haiku-4-5-20251001-v1:0") .outputSchema(jsonSchema) .build())); String content = response.getResult().getOutput().getText(); ---- NOTE: AWS Bedrock structured output uses a fixed schema name `response_schema` internally when constructing the `OutputConfig`. The schema JSON is passed directly to the AWS SDK's `JsonSchemaDefinition`. For more information, see the xref:api/structured-output-converter.adoc[Structured Output Converter] documentation. == Multimodal Multimodality 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. The Bedrock Converse API supports multimodal inputs, including text and image inputs, and can generate a text response based on the combined input. You need a model that supports multimodal inputs, such as the Anthropic Claude or Amazon Nova models. === Images For 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. Currently, Bedrock Converse supports the `base64` encoded images of `image/jpeg`, `image/png`, `image/gif` and `image/webp` mime types. Spring AI's `Message` interface supports multimodal AI models by introducing the `Media` type. It 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. Below is a simple code example, demonstrating the combination of user text with an image. [source,java] ---- String response = ChatClient.create(chatModel) .prompt() .user(u -> u.text("Explain what do you see on this picture?") .media(Media.Format.IMAGE_PNG, new ClassPathResource("/test.png"))) .call() .content(); logger.info(response); ---- It takes as an input the `test.png` image: image::multimodal.test.png[Multimodal Test Image, 200, 200, align="left"] along with the text message "Explain what do you see on this picture?", and generates a response something like: ---- The image shows a close-up view of a wire fruit basket containing several pieces of fruit. ... ---- === Video The 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. Currently, 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. Spring AI's `Message` interface supports multimodal AI models by introducing the `Media` type. It 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. Below is a simple code example, demonstrating the combination of user text with a video. [source,java] ---- String response = ChatClient.create(chatModel) .prompt() .user(u -> u.text("Explain what do you see in this video?") .media(Media.Format.VIDEO_MP4, new ClassPathResource("/test.video.mp4"))) .call() .content(); logger.info(response); ---- It takes as an input the `test.video.mp4` image: image::test.video.jpeg[Multimodal Test Video, 200, 200, align="left"] along with the text message "Explain what do you see in this video?", and generates a response something like: ---- The video shows a group of baby chickens, also known as chicks, huddled together on a surface ... ---- === Documents For some models, Bedrock allows you to include documents in the payload through Converse API document support, which can be provided in bytes. The document support has two different variants as explained below: - **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. - **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. Currently 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. Below is a simple code example, demonstrating the combination of user text with a media document. [source,java] ---- String response = ChatClient.create(chatModel) .prompt() .user(u -> u.text( "You are a very professional document summarization specialist.

You can interact with DeepSeek language models and create a multilingual conversational assistant based on DeepSeek models. == Prerequisites You will need to create an API key with DeepSeek to access DeepSeek language models. Create 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]. The 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. You can set this configuration property in your `application.properties` file: [source,properties] ---- spring.ai.deepseek.api-key= ---- For enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference a custom environment variable: [source,yaml] ---- # In application.yml spring: ai: deepseek: api-key: ${DEEPSEEK_API_KEY} ---- [source,bash] ---- # In your environment or .env file export DEEPSEEK_API_KEY= ---- You can also set this configuration programmatically in your application code: [source,java] ---- // Retrieve API key from a secure source or environment variable String apiKey = System.getenv("DEEPSEEK_API_KEY"); ---- === Add Repositories and BOM Spring AI artifacts are published in the Spring Milestone and Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration Spring AI provides Spring Boot auto-configuration for the DeepSeek Chat Model. To enable it, add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-model-deepseek ---- or to your Gradle `build.gradle` file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-deepseek' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Chat Properties ==== Retry Properties The prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the DeepSeek Chat model. [cols="3,5,1"] |==== | Property | Description | Default | spring.ai.retry.max-attempts | Maximum number of retry attempts. | 10 | spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. | 2 sec. | spring.ai.retry.backoff.multiplier | Backoff interval multiplier. | 5 | spring.ai.retry.backoff.max-interval | Maximum backoff duration. | 3 min. | spring.ai.retry.on-client-errors | If false, throws a NonTransientAiException, and does not attempt a retry for `4xx` client error codes | false | spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty | spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty |==== ==== Connection Properties The prefix `spring.ai.deepseek` is used as the property prefix that lets you connect to DeepSeek. [cols="3,5,1"] |==== | Property | Description | Default | spring.ai.deepseek.base-url | The URL to connect to | `+https://api.deepseek.com+` | spring.ai.deepseek.api-key | The API Key | - |==== ==== Configuration Properties The prefix `spring.ai.deepseek.chat` is the property prefix that lets you configure the chat model implementation for DeepSeek. [cols="3,5,1"] |==== | Property | Description | Default | spring.ai.deepseek.chat.enabled | Enables the DeepSeek chat model. | true | spring.ai.deepseek.chat.base-url | Optionally overrides the spring.ai.deepseek.base-url to provide a chat-specific URL | `+https://api.deepseek.com/+` | spring.ai.deepseek.chat.api-key | Optionally overrides the spring.ai.deepseek.api-key to provide a chat-specific API key | - | spring.ai.deepseek.chat.completions-path | The path to the chat completions endpoint | `/chat/completions` | spring.ai.deepseek.chat.beta-prefix-path | The prefix path to the beta feature endpoint | `/beta` | spring.ai.deepseek.chat.options.model | ID of the model to use. You can use either deepseek-reasoner or deepseek-chat. | deepseek-chat | 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 | 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. | - | 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 | spring.ai.deepseek.chat.options.stop | Up to 4 sequences where the API will stop generating further tokens. | - | 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 | 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 | 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. | - | 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. | - | 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. | - | spring.ai.deepseek.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | - | 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 |==== NOTE: You can override the common `spring.ai.deepseek.base-url` and `spring.ai.deepseek.api-key` for the `ChatModel` implementations. The `spring.ai.deepseek.chat.base-url` and `spring.ai.deepseek.chat.api-key` properties, if set, take precedence over the common properties. This is useful if you want to use different DeepSeek accounts for different models and different model endpoints. TIP: All properties prefixed with `spring.ai.deepseek.chat.options` can be overridden at runtime by adding a request-specific <> to the `Prompt` call. == Runtime Options [[chat-options]] The 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. On startup, the default options can be configured with the `DeepSeekChatModel(api, options)` constructor or the `spring.ai.deepseek.chat.options.*` properties. At runtime, you can override the default options by adding new, request-specific options to the `Prompt` call. For example, to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates. Please provide the JSON response without any code block markers such as ```json```.", DeepSeekChatOptions.builder() .withModel(DeepSeekApi.ChatModel.DEEPSEEK_CHAT.getValue()) .withTemperature(0.8f) .build() )); ---- TIP: 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()]. == Sample Controller (Auto-configuration) https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-deepseek` to your pom (or gradle) dependencies. Add an `application.properties` file under the `src/main/resources` directory to enable and configure the DeepSeek Chat model: [source,application.properties] ---- spring.ai.deepseek.api-key=YOUR_API_KEY spring.ai.deepseek.chat.options.model=deepseek-chat spring.ai.deepseek.chat.options.temperature=0.8 ---- TIP: Replace the `api-key` with your DeepSeek credentials. This will create a `DeepSeekChatModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the chat model for text generation. [source,java] ---- @RestController public class ChatController { private final DeepSeekChatModel chatModel; @Autowired public ChatController(DeepSeekChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { var prompt = new Prompt(new UserMessage(message)); return chatModel.stream(prompt); } } ---- == Chat Prefix Completion The 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. When using prefix completion, the user must ensure that the last message in the messages list is a DeepSeekAssistantMessage. Below 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. [source,java] ---- @RestController public class CodeGenerateController { private final DeepSeekChatModel chatModel; @Autowired public ChatController(DeepSeekChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generatePythonCode") public String generate(@RequestParam(value = "message", defaultValue = "Please write quick sort code") String message) { UserMessage userMessage = new UserMessage(message); Message assistantMessage = DeepSeekAssistantMessage.prefixAssistantMessage("```python\\n"); Prompt prompt = new Prompt(List.of(userMessage, assistantMessage), ChatOptions.builder().stopSequences(List.of("```")).build()); ChatResponse response = chatModel.call(prompt); return response.getResult().getOutput().getText(); } } ---- == Reasoning Model (deepseek-reasoner) The `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. You can use the `DeepSeekAssistantMessage` to get the CoT content generated by `deepseek-reasoner`. [source,java] ---- public void deepSeekReasonerExample() { DeepSeekChatOptions promptOptions = DeepSeekChatOptions.builder() .model(DeepSeekApi.ChatModel.DEEPSEEK_REASONER.getValue()) .build(); Prompt prompt = new Prompt("9.11 and 9.8, which is greater?", promptOptions); ChatResponse response = chatModel.call(prompt); // Get the CoT content generated by deepseek-reasoner, only available when using deepseek-reasoner model DeepSeekAssistantMessage deepSeekAssistantMessage = (DeepSeekAssistantMessage) response.getResult().getOutput(); String reasoningContent = deepSeekAssistantMessage.getReasoningContent(); String text = deepSeekAssistantMessage.getText(); } ---- == Reasoning Model Multi-round Conversation In 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: image::deepseek_r1_multiround_example.png[Multimodal Test Image, align="center"] Please 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. [source,java] ---- public String deepSeekReasonerMultiRoundExample() { List messages = new ArrayList<>(); messages.add(new UserMessage("9.11 and 9.8, which is greater?")); DeepSeekChatOptions promptOptions = DeepSeekChatOptions.builder() .model(DeepSeekApi.ChatModel.DEEPSEEK_REASONER.getValue()) .build(); Prompt prompt = new Prompt(messages, promptOptions); ChatResponse response = chatModel.call(prompt); DeepSeekAssistantMessage deepSeekAssistantMessage = (DeepSeekAssistantMessage) response.getResult().getOutput(); String reasoningContent = deepSeekAssistantMessage.getReasoningContent(); String text = deepSeekAssistantMessage.getText(); messages.add(AssistantMessage.builder().content(Objects.requireNonNull(text)).build()); messages.add(new UserMessage("How many Rs are there in the word 'strawberry'?")); Prompt prompt2 = new Prompt(messages, promptOptions); ChatResponse response2 = chatModel.call(prompt2); DeepSeekAssistantMessage deepSeekAssistantMessage2 = (DeepSeekAssistantMessage) response2.getResult().getOutput(); String reasoningContent2 = deepSeekAssistantMessage2.getReasoningContent(); return deepSeekAssistantMessage2.getText(); } ---- == Manual Configuration The 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 <> to connect to the DeepSeek service. Add the `spring-ai-deepseek` dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-deepseek ---- or to your Gradle `build.gradle` file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-deepseek' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Next, create a `DeepSeekChatModel` and use it for text generation: [source,java] ---- DeepSeekApi deepSeekApi = DeepSeekApi.builder() .apiKey(System.getenv("DEEPSEEK_API_KEY")) .build(); DeepSeekChatOptions options = DeepSeekChatOptions.builder() .model(DeepSeekApi.ChatModel.DEEPSEEK_CHAT.getValue()) .temperature(0.4) .maxTokens(200) .build(); DeepSeekChatModel chatModel = DeepSeekChatModel.builder() .deepSeekApi(deepSeekApi) .defaultOptions(options) .build(); ChatResponse response = chatModel.call( new Prompt("Generate the names of 5 famous pirates.")); // Or with streaming responses Flux streamResponse = chatModel.stream( new Prompt("Generate the names of 5 famous pirates.")); ---- The `DeepSeekChatOptions` provides the configuration information for the chat requests. The `DeepSeekChatOptions.Builder` is a fluent options builder. === Low-level DeepSeekApi Client [[low-level-api]] The 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].

Must be set to `https://hub.docker.com/u/ai` | - | spring.ai.openai.api-key | Any string | - |==== ==== Configuration Properties [NOTE] ==== Enabling and disabling chat auto-configurations is now done via top level properties with the prefix `spring.ai.model.chat`. To enable, `spring.ai.model.chat=openai` (It is enabled by default) To disable, `spring.ai.model.chat=none` (or any value which doesn't match openai) This change allows for the configuration of multiple models in your application. ==== The prefix `spring.ai.openai.chat` is the property prefix that lets you configure the chat model implementation for OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.chat.enabled (Removed and no longer valid) | Enable OpenAI chat model. | true | spring.ai.model.chat | Enable OpenAI chat model. | openai | 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` | - | spring.ai.openai.chat.api-key | Optional overrides the spring.ai.openai.api-key to provide chat specific api-key | - | spring.ai.openai.chat.options.model | The link:https://hub.docker.com/u/ai[LLM model] to use | - | 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 | 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 | 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. | - | 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 | 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. | - | 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.| - | 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. | - | spring.ai.openai.chat.options.stop | Up to 4 sequences where the API will stop generating further tokens. | - | 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. | - | 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. | - | 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. | - | spring.ai.openai.chat.options.user | A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. | - | 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 | 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. | - | spring.ai.openai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | - | 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 |==== TIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding a request specific <> to the `Prompt` call. == Runtime Options [[chat-options]] The 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. On start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties. At run-time you can override the default options by adding new, request specific, options to the `Prompt` call. For example, to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", OpenAiChatOptions.builder() .model("ai/gemma3:4B-F16") .build() )); ---- TIP: 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()]. == Function Calling Docker Model Runner supports Tool/Function calling when selecting a model that supports it. You 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. This is a powerful technique for connecting the LLM capabilities with external tools and APIs. === Tool Example Here's a simple example of how to use Docker Model Runner function calling with Spring AI: [source,application.properties] ---- spring.ai.openai.api-key=test spring.ai.openai.base-url=http://localhost:12434/engines spring.ai.openai.chat.options.model=ai/gemma3:4B-F16 ---- [source,java] ---- @SpringBootApplication public class DockerModelRunnerLlmApplication { public static void main(String[] args) { SpringApplication.run(DockerModelRunnerLlmApplication.class, args); } @Bean CommandLineRunner runner(ChatClient.Builder chatClientBuilder) { return args -> { var chatClient = chatClientBuilder.build(); var response = chatClient.prompt() .user("What is the weather in Amsterdam and Paris?") .functions("weatherFunction") // reference by bean name. .call() .content(); System.out.println(response); }; } @Bean @Description("Get the weather in location") public Function weatherFunction() { return new MockWeatherService(); } public static class MockWeatherService implements Function { public record WeatherRequest(String location, String unit) {} public record WeatherResponse(double temp, String unit) {} @Override public WeatherResponse apply(WeatherRequest request) { double temperature = request.location().contains("Amsterdam") ? 20 : 25; return new WeatherResponse(temperature, request.unit); } } } ---- In this example, when the model needs weather information, it will automatically call the `weatherFunction` bean, which can then fetch real-time weather data. The expected response is: "The weather in Amsterdam is currently 20 degrees Celsius, and the weather in Paris is currently 25 degrees Celsius." Read more about OpenAI link:https://docs.spring.io/spring-ai/reference/api/chat/functions/openai-chat-functions.html[Function Calling]. == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies. Add a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model: [source,application.properties] ---- spring.ai.openai.api-key=test spring.ai.openai.base-url=http://localhost:12434/engines spring.ai.openai.chat.options.model=ai/gemma3:4B-F16 # Docker Model Runner doesn't support embeddings, so we need to disable them. spring.ai.openai.embedding.enabled=false ---- Here is an example of a simple `@Controller` class that uses the chat model for text generation. [source,java] ---- @RestController public class ChatController { private final OpenAiChatModel chatModel; @Autowired public ChatController(OpenAiChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chat/google-genai-chat.adoc ================================================ = Google GenAI Chat The https://ai.google.dev/gemini-api/docs[Google GenAI API] allows developers to build generative AI applications using Google's Gemini models through either the Gemini Developer API or Vertex AI. The Google GenAI API supports multimodal prompts as input and outputs text or code. A multimodal model is capable of processing information from multiple modalities, including images, videos, and text. For example, you can send the model a photo of a plate of cookies and ask it to give you a recipe for those cookies. Gemini is a family of generative AI models developed by Google DeepMind that is designed for multimodal use cases. The Gemini API gives you access to link:https://ai.google.dev/gemini-api/docs/models[various models] like Gemini Flash-Lite, Gemini Flash or Gemini Pro. This implementation provides two authentication modes: - **Gemini Developer API**: Use an API key for quick prototyping and development - **Vertex AI**: Use Google Cloud credentials for production deployments with enterprise features link:https://ai.google.dev/api[Gemini API Reference] == Prerequisites Choose one of the following authentication methods: === Option 1: Gemini Developer API (API Key) - Obtain an API key from the https://aistudio.google.com/app/apikey[Google AI Studio] - Set the API key as an environment variable or in your application properties === Option 2: Vertex AI (Google Cloud) - Install the link:https://cloud.google.com/sdk/docs/install[gcloud] CLI, appropriate for your OS. - Authenticate by running the following command. Replace `PROJECT_ID` with your Google Cloud project ID and `ACCOUNT` with your Google Cloud username. [source] ---- gcloud config set project && gcloud auth application-default login ---- == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the Google GenAI Chat Client. To enable it add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-google-genai ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-google-genai' } ---- ====== TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Chat Properties [NOTE] ==== Enabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`. To enable, spring.ai.model.chat=google-genai (It is enabled by default) To disable, spring.ai.model.chat=none (or any value which doesn't match google-genai) This change is done to allow configuration of multiple models. ==== ==== Connection Properties The prefix `spring.ai.google.genai` is used as the property prefix that lets you connect to Google GenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.model.chat | Enable Chat Model client | google-genai | spring.ai.google.genai.api-key | API key for Gemini Developer API.

At runtime, you can override the default options by adding new, request specific, options to the `Prompt` call. For example, to override the default temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", GoogleGenAiChatOptions.builder() .temperature(0.4) .build() )); ---- TIP: In addition to the model specific `GoogleGenAiChatOptions` 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()]. == Tool Calling The Google GenAI model supports tool calling (function calling) capabilities, allowing models to use tools during conversations. Here's an example of how to define and use `@Tool`-based tools: [source,java] ---- public class WeatherService { @Tool(description = "Get the weather in location") public String weatherByLocation(@ToolParam(description= "City or state name") String location) { ... } } String response = ChatClient.create(this.chatModel) .prompt("What's the weather like in Boston?") .tools(new WeatherService()) .call() .content(); ---- You can use the java.util.function beans as tools as well: [source,java] ---- @Bean @Description("Get the weather in location. Return temperature in 36°F or 36°C format.") public Function weatherFunction() { return new MockWeatherService(); } String response = ChatClient.create(this.chatModel) .prompt("What's the weather like in Boston?") .toolNames("weatherFunction") .inputType(Request.class) .call() .content(); ---- Find more in xref:api/tools.adoc[Tools] documentation. == Server-Side Tool Invocations [[server-side-tool-invocations]] When 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. [IMPORTANT] ==== This 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. ==== === Configuration Enable via application properties: [source,application.properties] ---- spring.ai.google.genai.chat.options.google-search-retrieval=true spring.ai.google.genai.chat.options.include-server-side-tool-invocations=true ---- Or programmatically at runtime: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "What are the latest developments in quantum computing?", GoogleGenAiChatOptions.builder() .model("gemini-2.0-flash") .googleSearchRetrieval(true) .includeServerSideToolInvocations(true) .build() )); ---- === Accessing Server-Side Tool Invocation Metadata When enabled, server-side tool invocations are available in the response message metadata under the `serverSideToolInvocations` key: [source,java] ---- ChatResponse response = chatModel.call(prompt); Map metadata = response.getResult().getOutput().getMetadata(); @SuppressWarnings("unchecked") List> invocations = (List>) metadata.get("serverSideToolInvocations"); if (invocations != null) { for (Map invocation : invocations) { String type = (String) invocation.get("type"); // "toolCall" or "toolResponse" String id = (String) invocation.get("id"); // Unique invocation ID String toolType = (String) invocation.get("toolType"); // e.g., "GOOGLE_SEARCH_WEB" if ("toolCall".equals(type)) { Map args = (Map) invocation.get("args"); // Inspect what the model searched for } else if ("toolResponse".equals(type)) { Map responseData = (Map) invocation.get("response"); // Inspect what search results the model received } } } ---- Each entry in the list contains: [cols="1,3", stripes=even] |==== | Field | Description | `type` | Either `"toolCall"` (the model's invocation request) or `"toolResponse"` (the server's result) | `id` | Unique identifier linking a `toolCall` to its corresponding `toolResponse` | `toolType` | The type of server-side tool (e.g., `GOOGLE_SEARCH_WEB`, `GOOGLE_SEARCH_IMAGE`, `URL_CONTEXT`, `GOOGLE_MAPS`) | `args` | (toolCall only) The arguments passed to the tool | `response` | (toolResponse only) The results returned by the tool |==== === Combined with Function Calling Server-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: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "What's the weather in San Francisco? Also search for the latest news about the city.", GoogleGenAiChatOptions.builder() .model("gemini-2.0-flash") .googleSearchRetrieval(true) .includeServerSideToolInvocations(true) .toolCallbacks(List.of( FunctionToolCallback.builder("get_current_weather", new WeatherService()) .description("Get the current weather in a given location") .inputType(WeatherRequest.class) .build())) .build() )); // The response contains: // - Weather data from the client-side function call (executed locally) // - Google Search invocations visible in metadata (executed server-side) ---- NOTE: 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. == Thinking Configuration [[thinking-config]] Gemini 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`. === Thinking Level The `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). [cols="1,3", stripes=even] |==== | Value | Description | `LOW` | Minimal thinking. Use for simple queries where speed is preferred over deep analysis. | `HIGH` | Extensive thinking. Use for complex problems requiring deep analysis and step-by-step reasoning. | `THINKING_LEVEL_UNSPECIFIED` | The model uses its default behavior. |==== ==== Configuration via Properties [source,application.properties] ---- spring.ai.google.genai.chat.options.model=gemini-3-pro-preview spring.ai.google.genai.chat.options.thinking-level=HIGH ---- ==== Programmatic Configuration [source,java] ---- import org.springframework.ai.google.genai.common.GoogleGenAiThinkingLevel; ChatResponse response = chatModel.call( new Prompt( "Explain the theory of relativity in simple terms.", GoogleGenAiChatOptions.builder() .model("gemini-3-pro-preview") .thinkingLevel(GoogleGenAiThinkingLevel.HIGH) .build() )); ---- === Thinking Budget The `thinkingBudget` option sets a token budget for the thinking process: - **Positive value**: Maximum number of tokens for thinking (e.g., `8192`) - **Zero (`0`)**: Disables thinking entirely - **Not set**: Model decides automatically based on query complexity [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Solve this complex math problem step by step.", GoogleGenAiChatOptions.builder() .model("gemini-2.5-pro") .thinkingBudget(8192) .build() )); ---- === Option Compatibility [IMPORTANT] ==== **`thinkingLevel` and `thinkingBudget` are mutually exclusive.** You cannot use both in the same request - doing so will result in an API error. * Use `thinkingLevel` (`LOW`, `HIGH`) for **Gemini 3 Pro** models * Use `thinkingBudget` (token count) for **Gemini 2.5** series models ==== You can combine `includeThoughts` with either `thinkingLevel` or `thinkingBudget` (but not both): [source,java] ---- // For Gemini 3 Pro: use thinkingLevel + includeThoughts ChatResponse response = chatModel.call( new Prompt( "Analyze this complex scenario.", GoogleGenAiChatOptions.builder() .model("gemini-3-pro-preview") .thinkingLevel(GoogleGenAiThinkingLevel.HIGH) .includeThoughts(true) .build() )); // For Gemini 2.5: use thinkingBudget + includeThoughts ChatResponse response = chatModel.call( new Prompt( "Analyze this complex scenario.", GoogleGenAiChatOptions.builder() .model("gemini-2.5-pro") .thinkingBudget(8192) .includeThoughts(true) .build() )); ---- === Model Support The thinking configuration options are model-specific: [cols="2,1,1,2", stripes=even] |==== | Model | thinkingLevel | thinkingBudget | Notes | Gemini 3 Pro (Preview) | ✅ Supported | ⚠️ Backwards compatible only | Use `thinkingLevel`. Cannot disable thinking. Requires **global** endpoint. | Gemini 2.5 Pro | ❌ Not supported | ✅ Supported | Use `thinkingBudget`. Set to 0 to disable, -1 for dynamic. | Gemini 2.5 Flash | ❌ Not supported | ✅ Supported | Use `thinkingBudget`. Set to 0 to disable, -1 for dynamic. | Gemini 2.5 Flash-Lite | ❌ Not supported | ✅ Supported | Thinking disabled by default. Set `thinkingBudget` to enable. | Gemini 2.0 Flash | ❌ Not supported | ❌ Not supported | Thinking not available. |==== [IMPORTANT] ==== * Using `thinkingLevel` with unsupported models (e.g., Gemini 2.5 or earlier) will result in an API error. * Gemini 3 Pro Preview is only available on **global** endpoints. Set `spring.ai.google.genai.location=global` or `GOOGLE_CLOUD_LOCATION=global`. * Check the https://ai.google.dev/gemini-api/docs/thinking[Google GenAI Thinking documentation] for the latest model capabilities. ==== NOTE: Enabling thinking features increases token usage and API costs. Use appropriately based on the complexity of your queries. == Thought Signatures [[thought-signatures]] Gemini 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. === When Thought Signatures Matter **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. Per https://ai.google.dev/gemini-api/docs/thought-signatures[Google's documentation]: * Validation is enforced for function calls within the current turn only * Previous turn signatures do not need to be preserved * Missing signatures in the current turn's function calls result in HTTP 400 errors for Gemini 3 Pro * For parallel function calls, only the first `functionCall` part carries the signature For Gemini 2.5 Pro and earlier models, thought signatures are optional and the API is lenient. === Configuration Enable thought signatures using configuration properties: [source,application.properties] ---- spring.ai.google.genai.chat.options.model=gemini-3-pro-preview spring.ai.google.genai.chat.options.include-thoughts=true ---- Or programmatically at runtime: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Your question here", GoogleGenAiChatOptions.builder() .model("gemini-3-pro-preview") .includeThoughts(true) .toolCallbacks(callbacks) .build() )); ---- === Automatic Handling Spring AI automatically handles thought signatures during the internal tool execution loop. When `internalToolExecutionEnabled` is true (the default), Spring AI: 1. **Extracts** thought signatures from model responses 2. **Attaches** them to the correct `functionCall` parts when sending back function responses 3. **Propagates** them correctly during function calls within a single turn (both parallel and sequential) You don't need to manually manage thought signatures - Spring AI ensures they are properly attached to `functionCall` parts as required by the API specification. === Example with Function Calling [source,java] ---- @Bean @Description("Get the weather in a location") public Function weatherFunction() { return new WeatherService(); } // Enable includeThoughts for Gemini 3 Pro with function calling String response = ChatClient.create(this.chatModel) .prompt("What's the weather like in Boston?") .options(GoogleGenAiChatOptions.builder() .model("gemini-3-pro-preview") .includeThoughts(true) .build()) .toolNames("weatherFunction") .call() .content(); ---- === Manual Tool Execution Mode If 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`. **Requirements for manual tool execution with thought signatures:** 1. Extract thought signatures from the response metadata: + [source,java] ---- AssistantMessage assistantMessage = response.getResult().getOutput(); Map metadata = assistantMessage.getMetadata(); List thoughtSignatures = (List) metadata.get("thoughtSignatures"); ---- 2. 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. 3. For Gemini 3 Pro, failing to preserve thought signatures during the current turn will result in HTTP 400 errors from the API. IMPORTANT: 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. NOTE: Enabling `includeThoughts` increases token usage as thought processes are included in responses. This impacts API costs but provides better reasoning transparency. == Multimodal Multimodality 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. === Image, Audio, Video Google's Gemini AI models support this capability by comprehending and integrating text, code, audio, images, and video. For more details, refer to the blog post https://blog.google/technology/ai/google-gemini-ai/#introducing-gemini[Introducing Gemini]. Spring AI's `Message` interface supports multimodal AI models by introducing the Media type. This 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. Below 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. [source,java] ---- byte[] data = new ClassPathResource("/vertex-test.png").getContentAsByteArray(); var userMessage = UserMessage.builder() .text("Explain what do you see o this picture?") .media(List.of(new Media(MimeTypeUtils.IMAGE_PNG, data))) .build(); ChatResponse response = chatModel.call(new Prompt(List.of(this.userMessage))); ---- === PDF Google GenAI provides support for PDF input types. Use the `application/pdf` media type to attach a PDF file to the message: [source,java] ---- var pdfData = new ClassPathResource("/spring-ai-reference-overview.pdf"); var userMessage = UserMessage.builder() .text("You are a very professional document summarization specialist. Please summarize the given document.") .media(List.of(new Media(new MimeType("application", "pdf"), pdfData))) .build(); var response = this.chatModel.call(new Prompt(List.of(userMessage))); ---- == Cached Content [[cached-content]] Google 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. === Benefits - **Cost Reduction**: Cached tokens are billed at a much lower rate than regular input tokens (typically 75-90% cheaper) - **Improved Performance**: Reusing cached content reduces processing time for large contexts - **Consistency**: Same cached context ensures consistent responses across multiple requests === Cache Requirements - Minimum cache size: 32,768 tokens (approximately 25,000 words) - Maximum cache duration: 1 hour by default (configurable via TTL) - Cached content must include either system instructions or conversation history === Using Cached Content Service Spring AI provides `GoogleGenAiCachedContentService` for programmatic cache management. The service is automatically configured when using the Spring Boot auto-configuration. ==== Creating Cached Content [source,java] ---- @Autowired private GoogleGenAiCachedContentService cachedContentService; // Create cached content with a large document String largeDocument = "... your large context here (>32k tokens) ..."; CachedContentRequest request = CachedContentRequest.builder() .model("gemini-2.0-flash") .contents(List.of( Content.builder() .role("user") .parts(List.of(Part.fromText(largeDocument))) .build() )) .displayName("My Large Document Cache") .ttl(Duration.ofHours(1)) .build(); GoogleGenAiCachedContent cachedContent = cachedContentService.create(request); String cacheName = cachedContent.getName(); // Save this for reuse ---- ==== Using Cached Content in Chat Requests Once you've created cached content, reference it in your chat requests: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Summarize the key points from the document", GoogleGenAiChatOptions.builder() .useCachedContent(true) .cachedContentName(cacheName) // Use the cached content name .build() )); ---- Or via configuration properties: [source,application.properties] ---- spring.ai.google.genai.chat.options.use-cached-content=true spring.ai.google.genai.chat.options.cached-content-name=cachedContent/your-cache-name ---- ==== Managing Cached Content The `GoogleGenAiCachedContentService` provides comprehensive cache management: [source,java] ---- // Retrieve cached content GoogleGenAiCachedContent content = cachedContentService.get(cacheName); // Update cache TTL CachedContentUpdateRequest updateRequest = CachedContentUpdateRequest.builder() .ttl(Duration.ofHours(2)) .build(); GoogleGenAiCachedContent updated = cachedContentService.update(cacheName, updateRequest); // List all cached content List allCaches = cachedContentService.listAll(); // Delete cached content boolean deleted = cachedContentService.delete(cacheName); // Extend cache TTL GoogleGenAiCachedContent extended = cachedContentService.extendTtl(cacheName, Duration.ofMinutes(30)); // Cleanup expired caches int removedCount = cachedContentService.cleanupExpired(); ---- ==== Asynchronous Operations All operations have asynchronous variants: [source,java] ---- CompletableFuture futureCache = cachedContentService.createAsync(request); CompletableFuture futureGet = cachedContentService.getAsync(cacheName); CompletableFuture futureDelete = cachedContentService.deleteAsync(cacheName); ---- === Auto-Caching Spring AI can automatically cache large prompts when they exceed a specified token threshold: [source,application.properties] ---- # Automatically cache prompts larger than 100,000 tokens spring.ai.google.genai.chat.options.auto-cache-threshold=100000 # Set auto-cache TTL to 1 hour spring.ai.google.genai.chat.options.auto-cache-ttl=PT1H ---- Or programmatically: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( largePrompt, GoogleGenAiChatOptions.builder() .autoCacheThreshold(100000) .autoCacheTtl(Duration.ofHours(1)) .build() )); ---- NOTE: 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. === Monitoring Cache Usage Cached content includes usage metadata accessible via the service: [source,java] ---- GoogleGenAiCachedContent content = cachedContentService.get(cacheName); // Check if cache is expired boolean expired = content.isExpired(); // Get remaining TTL Duration remaining = content.getRemainingTtl(); // Get usage metadata CachedContentUsageMetadata metadata = content.getUsageMetadata(); if (metadata != null) { System.out.println("Total tokens: " + metadata.totalTokenCount().orElse(0)); } ---- === Best Practices 1. **Cache Lifetime**: Set appropriate TTL based on your use case. Shorter TTLs for frequently changing content, longer for static content. 2. **Cache Naming**: Use descriptive display names to identify cached content easily. 3. **Cleanup**: Periodically clean up expired caches to maintain organization. 4. **Token Threshold**: Only cache content that exceeds the minimum threshold (32,768 tokens). 5. **Cost Optimization**: Reuse cached content across multiple requests to maximize cost savings. === Configuration Example Complete configuration example: [source,application.properties] ---- # Enable cached content service (enabled by default) spring.ai.google.genai.chat.enable-cached-content=true # Use a specific cached content spring.ai.google.genai.chat.options.use-cached-content=true spring.ai.google.genai.chat.options.cached-content-name=cachedContent/my-cache-123 # Auto-caching configuration spring.ai.google.genai.chat.options.auto-cache-threshold=50000 spring.ai.google.genai.chat.options.auto-cache-ttl=PT30M ---- == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-google-genai` to your pom (or gradle) dependencies. Add a `application.properties` file, under the `src/main/resources` directory, to enable and configure the Google GenAI chat model: === Using Gemini Developer API (API Key) [source,application.properties] ---- spring.ai.google.genai.api-key=YOUR_API_KEY spring.ai.google.genai.chat.options.model=gemini-2.0-flash spring.ai.google.genai.chat.options.temperature=0.5 ---- === Using Vertex AI [source,application.properties] ---- spring.ai.google.genai.project-id=PROJECT_ID spring.ai.google.genai.location=LOCATION spring.ai.google.genai.chat.options.model=gemini-2.0-flash spring.ai.google.genai.chat.options.temperature=0.5 ---- TIP: Replace the `project-id` with your Google Cloud Project ID and `location` is Google Cloud Region like `us-central1`, `europe-west1`, etc... [NOTE] ==== Each model has its own set of supported regions, you can find the list of supported regions in the model page. ==== This will create a `GoogleGenAiChatModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the chat model for text generations. [source,java] ---- @RestController public class ChatController { private final GoogleGenAiChatModel chatModel; @Autowired public ChatController(GoogleGenAiChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- == Manual Configuration The 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. Add the `spring-ai-google-genai` dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-google-genai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-google-genai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Next, create a `GoogleGenAiChatModel` and use it for text generations: === Using API Key [source,java] ---- Client genAiClient = Client.builder() .apiKey(System.getenv("GOOGLE_API_KEY")) .build(); var chatModel = new GoogleGenAiChatModel(genAiClient, GoogleGenAiChatOptions.builder() .model(ChatModel.GEMINI_2_0_FLASH) .temperature(0.4) .build()); ChatResponse response = this.chatModel.call( new Prompt("Generate the names of 5 famous pirates.")); ---- === Using Vertex AI [source,java] ---- Client genAiClient = Client.builder() .project(System.getenv("GOOGLE_CLOUD_PROJECT")) .location(System.getenv("GOOGLE_CLOUD_LOCATION")) .vertexAI(true) .build(); var chatModel = new GoogleGenAiChatModel(genAiClient, GoogleGenAiChatOptions.builder() .model(ChatModel.GEMINI_2_0_FLASH) .temperature(0.4) .build()); ChatResponse response = this.chatModel.call( new Prompt("Generate the names of 5 famous pirates.")); ---- The `GoogleGenAiChatOptions` provides the configuration information for the chat requests. The `GoogleGenAiChatOptions.Builder` is fluent options builder. == Migration from Vertex AI Gemini If you were previously using the Vertex AI Gemini implementation (`spring-ai-vertex-ai-gemini`), which has been removed, migrate to Google GenAI: Key Differences: 1. **SDK**: Google GenAI uses the new `com.google.genai.Client` instead of `com.google.cloud.vertexai.VertexAI` 2. **Authentication**: Supports both API key and Google Cloud credentials (Vertex AI mode) 3. **Package Names**: Classes are in `org.springframework.ai.google.genai` instead of `org.springframework.ai.vertexai.gemini` 4. **Property Prefix**: Uses `spring.ai.google.genai` instead of `spring.ai.vertex.ai.gemini` Google GenAI supports both quick prototyping with API keys and production deployments using Vertex AI through Google Cloud credentials. == Low-level Java Client [[low-level-api]] The Google GenAI implementation is built on the new Google GenAI Java SDK, which provides a modern, streamlined API for accessing Gemini models. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chat/groq-chat.adoc ================================================ = Groq Chat https://groq.com/[Groq] is an extremely fast, LPU™ based, AI Inference Engine that support various https://console.groq.com/docs/models[AI Models], supports `Tool/Function Calling` and exposes a `OpenAI API` compatible endpoint. Spring AI integrates with the https://groq.com/[Groq] by reusing the existing xref::api/chat/openai-chat.adoc[OpenAI] client. For this you need to obtain a https://console.groq.com/keys[Groq Api Key], set the base-url to https://api.groq.com/openai and select one of the provided https://console.groq.com/docs/models[Groq models]. image::spring-ai-groq-integration.jpg[w=800,align="center"] NOTE: The Groq API is not fully compatible with the OpenAI API. Be aware for the following https://console.groq.com/docs/openai[compatibility constrains]. Additionally, currently Groq doesn't support multimodal messages. Check the https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/chat/proxy/GroqWithOpenAiChatModelIT.java[GroqWithOpenAiChatModelIT.java] tests for examples of using Groq with Spring AI. == Prerequisites * **Create an API Key**: Visit https://console.groq.com/keys[here] to create an API Key. The 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 groq.com. * **Set the Groq URL**: You have to set the `spring.ai.openai.base-url` property to `+https://api.groq.com/openai+`. * **Select a Groq Model**: Use the `spring.ai.openai.chat.model=` property to select from the available https://console.groq.com/docs/models[Groq Models]. You can set these configuration properties in your `application.properties` file: [source,properties] ---- spring.ai.openai.api-key= spring.ai.openai.base-url=https://api.groq.com/openai spring.ai.openai.chat.model=llama3-70b-8192 ---- For enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference custom environment variables: [source,yaml] ---- # In application.yml spring: ai: openai: api-key: ${GROQ_API_KEY} base-url: ${GROQ_BASE_URL} chat: model: ${GROQ_MODEL} ---- [source,bash] ---- # In your environment or .env file export GROQ_API_KEY= export GROQ_BASE_URL=https://api.groq.com/openai export GROQ_MODEL=llama3-70b-8192 ---- You can also set these configurations programmatically in your application code: [source,java] ---- // Retrieve configuration from secure sources or environment variables String apiKey = System.getenv("GROQ_API_KEY"); String baseUrl = System.getenv("GROQ_BASE_URL"); String model = System.getenv("GROQ_MODEL"); ---- === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the OpenAI Chat Client. To enable it add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-openai' } ---- ====== TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Chat Properties ==== Retry Properties The prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the OpenAI chat model. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.retry.max-attempts | Maximum number of retry attempts. | 10 | spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. | 2 sec. | spring.ai.retry.backoff.multiplier | Backoff interval multiplier. | 5 | spring.ai.retry.backoff.max-interval | Maximum backoff duration. | 3 min. | spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false | spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty | spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty |==== ==== Connection Properties The prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.base-url | The URL to connect to. Must be set to `+https://api.groq.com/openai+` | - | spring.ai.openai.api-key | The Groq API Key | - |==== ==== Configuration Properties [NOTE] ==== Enabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`. To enable, spring.ai.model.chat=openai (It is enabled by default) To disable, spring.ai.model.chat=none (or any value which doesn't match openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.openai.chat` is the property prefix that lets you configure the chat model implementation for OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.chat.enabled (Removed and no longer valid) | Enable OpenAI chat model. | true | spring.ai.openai.chat | Enable OpenAI chat model. | openai | spring.ai.openai.chat.base-url | Optional overrides the spring.ai.openai.base-url to provide chat specific url. Must be set to `+https://api.groq.com/openai+` | - | spring.ai.openai.chat.api-key | Optional overrides the spring.ai.openai.api-key to provide chat specific api-key | - | spring.ai.openai.chat.options.model | The https://console.groq.com/docs/models[available model] names are `llama3-8b-8192`, `llama3-70b-8192`, `mixtral-8x7b-32768`, `gemma2-9b-it`. | - | 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 | 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 | 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. | - | 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 | 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. | - | 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.| - | 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. | - | spring.ai.openai.chat.options.stop | Up to 4 sequences where the API will stop generating further tokens. | - | 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. | - | 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. | - | 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. | - | spring.ai.openai.chat.options.user | A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. | - | 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 | 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. | - | spring.ai.openai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | - | 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 |==== TIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding a request specific <> to the `Prompt` call. == Runtime Options [[chat-options]] The 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. On start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties. At run-time you can override the default options by adding new, request specific, options to the `Prompt` call. For example to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", OpenAiChatOptions.builder() .model("mixtral-8x7b-32768") .temperature(0.4) .build() )); ---- TIP: 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()]. == Function Calling Groq API endpoints support https://console.groq.com/docs/tool-use[tool/function calling] when selecting one of the Tool/Function supporting models. TIP: Check the Tool https://console.groq.com/docs/tool-use[Supported Models]. image::spring-ai-groq-functions-2.jpg[w=800,align="center"] You 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. This is a powerful technique to connect the LLM capabilities with external tools and APIs. === Tool Example Here's a simple example of how to use Groq function calling with Spring AI: [source,java] ---- @SpringBootApplication public class GroqApplication { public static void main(String[] args) { SpringApplication.run(GroqApplication.class, args); } @Bean CommandLineRunner runner(ChatClient.Builder chatClientBuilder) { return args -> { var chatClient = chatClientBuilder.build(); var response = chatClient.prompt() .user("What is the weather in Amsterdam and Paris?") .functions("weatherFunction") // reference by bean name. .call() .content(); System.out.println(response); }; } @Bean @Description("Get the weather in location") public Function weatherFunction() { return new MockWeatherService(); } public static class MockWeatherService implements Function { public record WeatherRequest(String location, String unit) {} public record WeatherResponse(double temp, String unit) {} @Override public WeatherResponse apply(WeatherRequest request) { double temperature = request.location().contains("Amsterdam") ? 20 : 25; return new WeatherResponse(temperature, request.unit); } } } ---- In this example, when the model needs weather information, it will automatically call the `weatherFunction` bean, which can then fetch real-time weather data. The expected response looks like this: "The weather in Amsterdam is currently 20 degrees Celsius, and the weather in Paris is currently 25 degrees Celsius." Read more about OpenAI link:https://docs.spring.io/spring-ai/reference/api/chat/functions/openai-chat-functions.html[Function Calling]. == Multimodal NOTE: Currently the Groq API doesn't support media content. == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies. Add a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model: [source,application.properties] ---- spring.ai.openai.api-key= spring.ai.openai.base-url=https://api.groq.com/openai spring.ai.openai.chat.options.model=llama3-70b-8192 spring.ai.openai.chat.options.temperature=0.7 ---- TIP: replace the `api-key` with your OpenAI credentials. This will create a `OpenAiChatModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the chat model for text generations. [source,java] ---- @RestController public class ChatController { private final OpenAiChatModel chatModel; @Autowired public ChatController(OpenAiChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- == Manual Configuration The 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 <> to connect to the OpenAI service.

You can interact with MiniMax language models and create a multilingual conversational assistant based on MiniMax models. == Prerequisites You will need to create an API with MiniMax to access MiniMax language models. Create an account at https://www.minimaxi.com/login[MiniMax registration page] and generate the token on the https://www.minimaxi.com/user-center/basic-information/interface-key[API Keys page]. The Spring AI project defines a configuration property named `spring.ai.minimax.api-key` that you should set to the value of the `API Key` obtained from the API Keys page. You can set this configuration property in your `application.properties` file: [source,properties] ---- spring.ai.minimax.api-key= ---- For enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference an environment variable: [source,yaml] ---- # In application.yml spring: ai: minimax: api-key: ${MINIMAX_API_KEY} ---- [source,bash] ---- # In your environment or .env file export MINIMAX_API_KEY= ---- You can also set this configuration programmatically in your application code: [source,java] ---- // Retrieve API key from a secure source or environment variable String apiKey = System.getenv("MINIMAX_API_KEY"); ---- === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the MiniMax Chat Client. To enable it add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-model-minimax ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-minimax' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Chat Properties ==== Retry Properties The prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the MiniMax chat model. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.retry.max-attempts | Maximum number of retry attempts. | 10 | spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. | 2 sec. | spring.ai.retry.backoff.multiplier | Backoff interval multiplier. | 5 | spring.ai.retry.backoff.max-interval | Maximum backoff duration. | 3 min. | spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false | spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty | spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty |==== ==== Connection Properties The prefix `spring.ai.minimax` is used as the property prefix that lets you connect to MiniMax. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.minimax.base-url | The URL to connect to | https://api.minimax.chat | spring.ai.minimax.api-key | The API Key | - |==== ==== Configuration Properties [NOTE] ==== Enabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`. To enable, spring.ai.model.chat=minimax (It is enabled by default) To disable, spring.ai.model.chat=none (or any value which doesn't match minimax) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.minimax.chat` is the property prefix that lets you configure the chat model implementation for MiniMax. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.minimax.chat.enabled (Removed and no longer valid) | Enable MiniMax chat model. | true | spring.ai.model.chat | Enable MiniMax chat model. | minimax | spring.ai.minimax.chat.base-url | Optional overrides the spring.ai.minimax.base-url to provide chat specific url | https://api.minimax.chat | spring.ai.minimax.chat.api-key | Optional overrides the spring.ai.minimax.api-key to provide chat specific api-key | - | spring.ai.minimax.chat.options.model | This is the MiniMax Chat model to use | `abab6.5g-chat` (the `abab5.5-chat`, `abab5.5s-chat`, `abab6.5-chat`, `abab6.5g-chat`, `abab6.5t-chat` and `abab6.5s-chat` point to the latest model versions) | spring.ai.minimax.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. | - | spring.ai.minimax.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. | - | spring.ai.minimax.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. | 1.0 | spring.ai.minimax.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. Default value is 1 and cannot be greater than 5. Specifically, when the temperature is very small and close to 0, we can only return 1 result. If n is already set and>1 at this time, service will return an illegal input parameter (invalid_request_error) | 1 | spring.ai.minimax.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 | spring.ai.minimax.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 | spring.ai.minimax.chat.options.stop | The model will stop generating characters specified by stop, and currently only supports a single stop word in the format of ["stop_word1"] | - | spring.ai.minimax.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. | - | spring.ai.minimax.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | - | spring.ai.minimax.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 |==== NOTE: You can override the common `spring.ai.minimax.base-url` and `spring.ai.minimax.api-key` for the `ChatModel` implementations. The `spring.ai.minimax.chat.base-url` and `spring.ai.minimax.chat.api-key` properties if set take precedence over the common properties. This is useful if you want to use different MiniMax accounts for different models and different model endpoints. TIP: All properties prefixed with `spring.ai.minimax.chat.options` can be overridden at runtime by adding a request specific <> to the `Prompt` call. == Runtime Options [[chat-options]] The 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. On start-up, the default options can be configured with the `MiniMaxChatModel(api, options)` constructor or the `spring.ai.minimax.chat.options.*` properties. At run-time you can override the default options by adding new, request specific, options to the `Prompt` call. For example to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", MiniMaxChatOptions.builder() .model(MiniMaxApi.ChatModel.ABAB_6_5_S_Chat.getValue()) .temperature(0.5) .build() )); ---- TIP: 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()]. == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-minimax` to your pom (or gradle) dependencies. Add a `application.properties` file, under the `src/main/resources` directory, to enable and configure the MiniMax chat model: [source,application.properties] ---- spring.ai.minimax.api-key=YOUR_API_KEY spring.ai.minimax.chat.options.model=abab6.5g-chat spring.ai.minimax.chat.options.temperature=0.7 ---- TIP: replace the `api-key` with your MiniMax credentials. This will create a `MiniMaxChatModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the chat model for text generations. [source,java] ---- @RestController public class ChatController { private final MiniMaxChatModel chatModel; @Autowired public ChatController(MiniMaxChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { var prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- == Manual Configuration The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-minimax/src/main/java/org/springframework/ai/minimax/MiniMaxChatModel.java[MiniMaxChatModel] implements the `ChatModel` and `StreamingChatModel` and uses the <> to connect to the MiniMax service.

This is useful if you want to use different Mistral AI accounts for different models and different model endpoints. TIP: All properties prefixed with `spring.ai.mistralai.chat.options` can be overridden at runtime by adding request-specific <> to the `Prompt` call. == Runtime Options [[chat-options]] The 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. On start-up, the default options can be configured with the `MistralAiChatModel(api, options)` constructor or the `spring.ai.mistralai.chat.options.*` properties. At run-time, you can override the default options by adding new, request-specific options to the `Prompt` call. For example, to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", MistralAiChatOptions.builder() .model(MistralAiApi.ChatModel.MISTRAL_LARGE.getValue()) .temperature(0.5) .build() )); ---- TIP: 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()]. == Function Calling You 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. This is a powerful technique to connect the LLM capabilities with external tools and APIs. Read more about xref:api/tools.adoc[Tool Calling]. == Structured Output [[structured-output]] Mistral AI supports native structured outputs through JSON Schema, ensuring the model generates responses that strictly conform to your specified structure. This feature is available for Mistral Small and later models. === Using ChatClient with Native Structured Output The simplest way to use structured output is with the `ChatClient` high-level API and the `ENABLE_NATIVE_STRUCTURED_OUTPUT` advisor: [source,java] ---- record ActorsFilms(String actor, List movies) {} ActorsFilms actorsFilms = ChatClient.create(chatModel).prompt() .advisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT) .user("Generate the filmography of 5 movies for Tom Hanks.") .call() .entity(ActorsFilms.class); ---- This approach automatically: - Generates a JSON schema from your Java class - Configures the model to use native structured output - Parses the response into your specified type === Using ResponseFormat Directly For more control, you can use the `ResponseFormat` class with `MistralAiChatOptions`: [source,java] ---- record MovieRecommendation(String title, String director, int year, String plotSummary) {} var options = MistralAiChatOptions.builder() .model(MistralAiApi.ChatModel.MISTRAL_SMALL.getValue()) .responseFormat(ResponseFormat.jsonSchema(MovieRecommendation.class)) .build(); ChatResponse response = chatModel.call( new Prompt("Recommend a classic science fiction movie.", options)); ---- The `ResponseFormat` class provides several factory methods: * `ResponseFormat.text()` - Returns plain text output (default) * `ResponseFormat.jsonObject()` - Returns valid JSON (no schema enforcement) * `ResponseFormat.jsonSchema(Class)` - Generates schema from a Java class * `ResponseFormat.jsonSchema(String)` - Uses a JSON schema string * `ResponseFormat.jsonSchema(Map)` - Uses a JSON schema map === JSON Mode vs Structured Output Mistral AI supports two JSON-related modes: * **JSON Mode** (`json_object`): Guarantees valid JSON output, but doesn't enforce a specific structure * **Structured Output** (`json_schema`): Guarantees output matching your JSON schema [source,java] ---- // JSON Mode - any valid JSON var jsonMode = MistralAiChatOptions.builder() .responseFormat(ResponseFormat.jsonObject()) .build(); // Structured Output - specific schema enforced var structuredOutput = MistralAiChatOptions.builder() .responseFormat(ResponseFormat.jsonSchema(MyClass.class)) .build(); ---- For more information about structured outputs, see the xref:api/structured-output-converter.adoc[Structured Output Converter] documentation. == Multimodal Multimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats. Mistral AI supports text and vision modalities. === Vision Mistral AI models that offer vision multimodal support include `pixtral-large-latest`. Refer to the link:https://docs.mistral.ai/capabilities/vision/[Vision] guide for more information. The 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. Spring 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. This 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. Below is a code example excerpted from `MistralAiChatModelIT.java`, illustrating the fusion of user text with an image. [source,java] ---- var imageResource = new ClassPathResource("/multimodal.test.png"); var userMessage = new UserMessage("Explain what do you see on this picture?", new Media(MimeTypeUtils.IMAGE_PNG, this.imageResource)); ChatResponse response = chatModel.call(new Prompt(this.userMessage, ChatOptions.builder().model(MistralAiApi.ChatModel.PIXTRAL_LARGE.getValue()).build())); ---- or the image URL equivalent: [source,java] ---- var userMessage = new UserMessage("Explain what do you see on this picture?", new Media(MimeTypeUtils.IMAGE_PNG, URI.create("https://docs.spring.io/spring-ai/reference/_images/multimodal.test.png"))); ChatResponse response = chatModel.call(new Prompt(this.userMessage, ChatOptions.builder().model(MistralAiApi.ChatModel.PIXTRAL_LARGE.getValue()).build())); ---- TIP: You can pass multiple images as well. The example shows a model taking as an input the `multimodal.test.png` image: image::multimodal.test.png[Multimodal Test Image, 200, 200, align="left"] along with the text message "Explain what do you see on this picture?", and generating a response like this: ---- This is an image of a fruit bowl with a simple design. The bowl is made of metal with curved wire edges that create an open structure, allowing the fruit to be visible from all angles. Inside the bowl, there are two yellow bananas resting on top of what appears to be a red apple. The bananas are slightly overripe, as indicated by the brown spots on their peels. The bowl has a metal ring at the top, likely to serve as a handle for carrying. The bowl is placed on a flat surface with a neutral-colored background that provides a clear view of the fruit inside. ---- == OpenAI API Compatibility Mistral is OpenAI API-compatible and you can use the xref:api/chat/openai-chat.adoc[Spring AI OpenAI] client to talk to Mistrial. For 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= generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { var prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- == Manual Configuration The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-mistral-ai/src/main/java/org/springframework/ai/mistralai/MistralAiChatModel.java[MistralAiChatModel] implements the `ChatModel` and `StreamingChatModel` and uses the <> to connect to the Mistral AI service.

Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the OpenAI Chat Client. To enable it add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Chat Properties ==== Retry Properties The prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the OpenAI chat model. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.retry.max-attempts | Maximum number of retry attempts. | 10 | spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. | 2 sec. | spring.ai.retry.backoff.multiplier | Backoff interval multiplier. | 5 | spring.ai.retry.backoff.max-interval | Maximum backoff duration. | 3 min. | spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false | spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty | spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty |==== ==== Connection Properties The prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.base-url | The URL to connect to. Must be set to `+https://integrate.api.nvidia.com+` | - | spring.ai.openai.api-key | The NVIDIA API Key | - |==== ==== Configuration Properties [NOTE] ==== Enabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`. To enable, spring.ai.model.chat=openai (It is enabled by default) To disable, spring.ai.model.chat=none (or any value which doesn't match openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.openai.chat` is the property prefix that lets you configure the chat model implementation for OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.chat.enabled (Removed and no longer valid) | Enable OpenAI chat model. | true | spring.ai.model.chat | Enable OpenAI chat model. | openai | spring.ai.openai.chat.base-url | Optional overrides the spring.ai.openai.base-url to provide chat specific url. Must be set to `+https://integrate.api.nvidia.com+` | - | spring.ai.openai.chat.api-key | Optional overrides the spring.ai.openai.api-key to provide chat specific api-key | - | spring.ai.openai.chat.options.model | The link:https://docs.api.nvidia.com/nim/reference/llm-apis#models[NVIDIA LLM model] to use | - | 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 | 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 | 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. | NOTE: NVIDIA LLM API requires the `max-tokens` parameter to be explicitly set or server error will be thrown. | 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 | 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. | - | 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.| - | 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. | - | spring.ai.openai.chat.options.stop | Up to 4 sequences where the API will stop generating further tokens. | - | 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. | - | 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. | - | 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. | - | spring.ai.openai.chat.options.user | A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. | - | 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 | 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. | - | spring.ai.openai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | - | 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 |==== TIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding a request specific <> to the `Prompt` call. == Runtime Options [[chat-options]] The 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. On start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties. At run-time you can override the default options by adding new, request specific, options to the `Prompt` call. For example to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", OpenAiChatOptions.builder() .model("mixtral-8x7b-32768") .temperature(0.4) .build() )); ---- TIP: 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()]. == Function Calling NVIDIA LLM API supports Tool/Function calling when selecting a model that supports it. image::spring-ai-nvidia-function-calling.jpg[w=800,align="center"] You 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. This is a powerful technique to connect the LLM capabilities with external tools and APIs. === Tool Example Here's a simple example of how to use NVIDIA LLM API function calling with Spring AI: [source,application.properties] ---- spring.ai.openai.api-key=${NVIDIA_API_KEY} spring.ai.openai.base-url=https://integrate.api.nvidia.com spring.ai.openai.chat.options.model=meta/llama-3.1-70b-instruct spring.ai.openai.chat.options.max-tokens=2048 ---- [source,java] ---- @SpringBootApplication public class NvidiaLlmApplication { public static void main(String[] args) { SpringApplication.run(NvidiaLlmApplication.class, args); } @Bean CommandLineRunner runner(ChatClient.Builder chatClientBuilder) { return args -> { var chatClient = chatClientBuilder.build(); var response = chatClient.prompt() .user("What is the weather in Amsterdam and Paris?") .functions("weatherFunction") // reference by bean name. .call() .content(); System.out.println(response); }; } @Bean @Description("Get the weather in location") public Function weatherFunction() { return new MockWeatherService(); } public static class MockWeatherService implements Function { public record WeatherRequest(String location, String unit) {} public record WeatherResponse(double temp, String unit) {} @Override public WeatherResponse apply(WeatherRequest request) { double temperature = request.location().contains("Amsterdam") ? 20 : 25; return new WeatherResponse(temperature, request.unit); } } } ---- In this example, when the model needs weather information, it will automatically call the `weatherFunction` bean, which can then fetch real-time weather data. The expected response looks like this: "The weather in Amsterdam is currently 20 degrees Celsius, and the weather in Paris is currently 25 degrees Celsius." Read more about OpenAI link:https://docs.spring.io/spring-ai/reference/api/chat/functions/openai-chat-functions.html[Function Calling]. == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies. Add a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model: [source,application.properties] ---- spring.ai.openai.api-key=${NVIDIA_API_KEY} spring.ai.openai.base-url=https://integrate.api.nvidia.com spring.ai.openai.chat.options.model=meta/llama-3.1-70b-instruct # The NVIDIA LLM API doesn't support embeddings, so we need to disable it. spring.ai.openai.embedding.enabled=false # The NVIDIA LLM API requires this parameter to be set explicitly or server internal error will be thrown. spring.ai.openai.chat.options.max-tokens=2048 ---- TIP: replace the `api-key` with your NVIDIA credentials. NOTE: NVIDIA LLM API requires the `max-token` parameter to be explicitly set or server error will be thrown. Here is an example of a simple `@Controller` class that uses the chat model for text generations. [source,java] ---- @RestController public class ChatController { private final OpenAiChatModel chatModel; @Autowired public ChatController(OpenAiChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chat/ollama-chat.adoc ================================================ = Ollama Chat With https://ollama.ai/[Ollama] you can run various Large Language Models (LLMs) locally and generate text from them. Spring AI supports the Ollama chat completion capabilities with the `OllamaChatModel` API. TIP: Ollama offers an OpenAI API compatible endpoint as well.

To enable completions to return logprobs, this must be true. | - | spring.ai.ollama.chat.options.vocab-only | Load only the vocabulary, not the weights. | - | 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 | 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 | 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 | spring.ai.ollama.chat.options.num-keep | - | 4 | 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 | spring.ai.ollama.chat.options.num-predict | Maximum number of tokens to predict when generating text. (-1 = infinite generation, -2 = fill context) | -1 | 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 | 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 | 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 | 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 | spring.ai.ollama.chat.options.typical-p | - | 1.0 | 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 | spring.ai.ollama.chat.options.temperature | The temperature of the model. Increasing the temperature will make the model answer more creatively. | 0.8 | 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 | spring.ai.ollama.chat.options.presence-penalty | - | 0.0 | spring.ai.ollama.chat.options.frequency-penalty | - | 0.0 | spring.ai.ollama.chat.options.mirostat | Enable Mirostat sampling for controlling perplexity. (default: 0, 0 = disabled, 1 = Mirostat, 2 = Mirostat 2.0) | 0 | 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 | 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 | spring.ai.ollama.chat.options.penalize-newline | - | true | 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. | - | 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. | - | spring.ai.ollama.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | - | 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 |==== TIP: All properties prefixed with `spring.ai.ollama.chat.options` can be overridden at runtime by adding request-specific <> to the `Prompt` call. == Runtime Options [[chat-options]] The 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. IMPORTANT: 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. On start-up, the default options can be configured with the `OllamaChatModel(api, options)` constructor or the `spring.ai.ollama.chat.options.*` properties. At run-time, you can override the default options by adding new, request-specific options to the `Prompt` call. For example, to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", OllamaChatOptions.builder() .model(OllamaModel.LLAMA3_1) .temperature(0.4) .build() )); ---- TIP: 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()]. [[auto-pulling-models]] == Auto-pulling Models Spring AI Ollama can automatically pull models when they are not available in your Ollama instance. This feature is particularly useful for development and testing as well as for deploying your applications to new environments. TIP: You can also pull, by name, any of the thousands, free, link:https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face Models]. There are three strategies for pulling models: * `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. * `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. * `never` (defined in `PullModelStrategy.NEVER`): Never pull the model automatically. CAUTION: 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. All models defined via configuration properties and default options can be automatically pulled at startup time. You can configure the pull strategy, timeout, and maximum number of retries using configuration properties: [source,yaml] ---- spring: ai: ollama: init: pull-model-strategy: always timeout: 60s max-retries: 1 ---- CAUTION: 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. You can initialize additional models at startup, which is useful for models used dynamically at runtime: [source,yaml] ---- spring: ai: ollama: init: pull-model-strategy: always chat: additional-models: - llama3.2 - qwen2.5 ---- If you want to apply the pulling strategy only to specific types of models, you can exclude chat models from the initialization task: [source,yaml] ---- spring: ai: ollama: init: pull-model-strategy: always chat: include: false ---- This configuration will apply the pulling strategy to all models except chat models. == Function Calling You 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. This is a powerful technique to connect the LLM capabilities with external tools and APIs. Read more about xref:api/tools.adoc[Tool Calling]. TIP: 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. == Thinking Mode (Reasoning) Ollama 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. TIP: Thinking mode helps you understand the model's reasoning process and can improve response quality for complex problems. IMPORTANT: *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()`. === Enabling Thinking Mode Most models (Qwen3, DeepSeek-v3.1, DeepSeek R1) support simple boolean enable/disable: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "How many letter 'r' are in the word 'strawberry'?", OllamaChatOptions.builder() .model("qwen3") .enableThinking() .build() )); // Access the thinking process String thinking = response.getResult().getMetadata().get("thinking"); String answer = response.getResult().getOutput().getText(); ---- You can also disable thinking explicitly: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "What is 2+2?", OllamaChatOptions.builder() .model("deepseek-r1") .disableThinking() .build() )); ---- === Thinking Levels (GPT-OSS Only) The GPT-OSS model requires explicit thinking levels instead of boolean values: [source,java] ---- // Low thinking level ChatResponse response = chatModel.call( new Prompt( "Generate a short headline", OllamaChatOptions.builder() .model("gpt-oss") .thinkLow() .build() )); // Medium thinking level ChatResponse response = chatModel.call( new Prompt( "Analyze this dataset", OllamaChatOptions.builder() .model("gpt-oss") .thinkMedium() .build() )); // High thinking level ChatResponse response = chatModel.call( new Prompt( "Solve this complex problem", OllamaChatOptions.builder() .model("gpt-oss") .thinkHigh() .build() )); ---- === Accessing Thinking Content The thinking content is available in the response metadata: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Calculate 17 × 23", OllamaChatOptions.builder() .model("deepseek-r1") .enableThinking() .build() )); // Get the reasoning process String thinking = response.getResult().getMetadata().get("thinking"); System.out.println("Reasoning: " + thinking); // Output: "17 × 20 = 340, 17 × 3 = 51, 340 + 51 = 391" // Get the final answer String answer = response.getResult().getOutput().getText(); System.out.println("Answer: " + answer); // Output: "The answer is 391" ---- === Streaming with Thinking Thinking mode works with streaming responses as well: [source,java] ---- Flux stream = chatModel.stream( new Prompt( "Explain quantum entanglement", OllamaChatOptions.builder() .model("qwen3") .enableThinking() .build() )); stream.subscribe(response -> { String thinking = response.getResult().getMetadata().get("thinking"); String content = response.getResult().getOutput().getText(); if (thinking != null && !thinking.isEmpty()) { System.out.println("[Thinking] " + thinking); } if (content != null && !content.isEmpty()) { System.out.println("[Response] " + content); } }); ---- NOTE: When thinking is disabled or not set, the `thinking` metadata field will be null or empty. == Multimodal Multimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats. Some 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]). For further details, refer to the link:https://llava-vl.github.io/[LLaVA: Large Language and Vision Assistant]. The 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. Spring 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. This 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. Below 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. [source,java] ---- var imageResource = new ClassPathResource("/multimodal.test.png"); var userMessage = new UserMessage("Explain what do you see on this picture?", new Media(MimeTypeUtils.IMAGE_PNG, this.imageResource)); ChatResponse response = chatModel.call(new Prompt(this.userMessage, OllamaChatOptions.builder().model(OllamaModel.LLAVA)).build()); ---- The example shows a model taking as an input the `multimodal.test.png` image: image::multimodal.test.png[Multimodal Test Image, 200, 200, align="left"] along with the text message "Explain what do you see on this picture?", and generating a response like this: ---- The image shows a small metal basket filled with ripe bananas and red apples. The basket is placed on a surface, which appears to be a table or countertop, as there's a hint of what seems like a kitchen cabinet or drawer in the background. There's also a gold-colored ring visible behind the basket, which could indicate that this photo was taken in an area with metallic decorations or fixtures. The overall setting suggests a home environment where fruits are being displayed, possibly for convenience or aesthetic purposes. ---- == Structured Outputs Ollama provides custom https://ollama.com/blog/structured-outputs[Structured Outputs] APIs that ensure your model generates responses conforming strictly to your provided `JSON Schema`. In addition to the existing Spring AI model-agnostic xref::api/structured-output-converter.adoc[Structured Output Converter], these APIs offer enhanced control and precision. === Two Modes for Structured Output Ollama supports two different modes for structured output through the `format` parameter: 1. **Simple "json" Format**: Instructs Ollama to return any valid JSON structure (unpredictable schema) 2. **JSON Schema Format**: Instructs Ollama to return JSON conforming to a specific schema (predictable structure) ==== Simple "json" Format Use this when you want JSON output but don't need a specific structure: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "List 3 countries in Europe", OllamaChatOptions.builder() .model("llama3.2") .format("json") // Any valid JSON .build() )); ---- The model can return any JSON structure it chooses: [source,json] ---- ["France", "Germany", "Italy"] // or {"countries": ["France", "Germany", "Italy"]} // or {"data": {"european_countries": ["France", "Germany", "Italy"]}} ---- ==== JSON Schema Format (Recommended for Production) Use this when you need a guaranteed, predictable structure: [source,java] ---- String jsonSchema = """ { "type": "object", "properties": { "countries": { "type": "array", "items": { "type": "string" } } }, "required": ["countries"] } """; ChatResponse response = chatModel.call( new Prompt( "List 3 countries in Europe", OllamaChatOptions.builder() .model("llama3.2") .outputSchema(jsonSchema) // Enforced schema .build() )); ---- The model **must** return this exact structure: [source,json] ---- {"countries": ["France", "Germany", "Italy"]} ---- === Configuration Spring AI allows you to configure your response format programmatically using the `OllamaChatOptions` builder. ==== Using the Chat Options Builder with JSON Schema You can set the response format programmatically with the `OllamaChatOptions` builder: [source,java] ---- String jsonSchema = """ { "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 } """; Prompt prompt = new Prompt("how can I solve 8x + 7 = -23", OllamaChatOptions.builder() .model(OllamaModel.LLAMA3_2.getName()) .outputSchema(jsonSchema) // Pass JSON Schema as string .build()); ChatResponse response = this.ollamaChatModel.call(this.prompt); ---- ==== Integrating with BeanOutputConverter Utilities You 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: [source,java] ---- record MathReasoning( @JsonProperty(required = true, value = "steps") Steps steps, @JsonProperty(required = true, value = "final_answer") String finalAnswer) { record Steps( @JsonProperty(required = true, value = "items") Items[] items) { record Items( @JsonProperty(required = true, value = "explanation") String explanation, @JsonProperty(required = true, value = "output") String output) { } } } var outputConverter = new BeanOutputConverter<>(MathReasoning.class); Prompt prompt = new Prompt("how can I solve 8x + 7 = -23", OllamaChatOptions.builder() .model(OllamaModel.LLAMA3_2.getName()) .outputSchema(outputConverter.getJsonSchema()) // Get JSON Schema as string .build()); ChatResponse response = this.ollamaChatModel.call(this.prompt); String content = this.response.getResult().getOutput().getText(); MathReasoning mathReasoning = this.outputConverter.convert(this.content); ---- NOTE: Ensure you use the `@JsonProperty(required = true,...)` annotation for generating a schema that accurately marks fields as `required`. Although this is optional for JSON Schema, it's recommended for the structured response to function correctly. === API Methods: `.format()` vs `.outputSchema()` Spring AI provides two methods for configuring structured output: [cols="2,3,3", options="header"] |==== | Method | Use Case | Example | `.format("json")` | Simple JSON mode - any structure | `.format("json")` | `.outputSchema(jsonSchemaString)` | JSON Schema mode - enforced structure | `.outputSchema("{\"type\":\"object\",...}")` | `.format(mapObject)` | JSON Schema mode - alternative API | `.format(new ObjectMapper().readValue(schema, Map.class))` |==== TIP: For most use cases, use `.outputSchema(jsonSchemaString)` for JSON Schema validation or `.format("json")` for simple JSON output. The `.format(Map)` approach is also supported but requires manual JSON parsing. == OpenAI API Compatibility Ollama 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. For 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`. TIP: 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]. This allows you to leverage Ollama's full capabilities while using the OpenAI client. image::spring-ai-ollama-over-openai.jpg[Ollama OpenAI API compatibility, 800, 600, align="center"] === Reasoning Content via OpenAI Compatibility Ollama's OpenAI-compatible endpoint supports the `reasoning_content` field for thinking-capable models (such as `qwen3:*-thinking`, `deepseek-r1`, `deepseek-v3.1`). When using the Spring AI OpenAI client with Ollama, the model's reasoning process is automatically captured and made available through the response metadata. NOTE: This is an alternative to using Ollama's native thinking mode API (documented in <> above). Both approaches work with Ollama's thinking models, but the OpenAI-compatible endpoint uses the `reasoning_content` field name instead of `thinking`. Here's an example of accessing reasoning content from Ollama through the OpenAI client: [source,java] ---- // Configure Spring AI OpenAI client to point to Ollama @Configuration class OllamaConfig { @Bean OpenAiChatModel ollamaChatModel() { var openAiApi = new OpenAiApi("http://localhost:11434", "ollama"); return new OpenAiChatModel(openAiApi, OpenAiChatOptions.builder() .model("deepseek-r1") // or qwen3, deepseek-v3.1, etc. .build()); } } // Use the model with thinking-capable models ChatResponse response = chatModel.call( new Prompt("How many letter 'r' are in the word 'strawberry'?")); // Access the reasoning process from metadata String reasoning = response.getResult().getMetadata().get("reasoningContent"); if (reasoning != null && !reasoning.isEmpty()) { System.out.println("Model's reasoning process:"); System.out.println(reasoning); } // Get the final answer String answer = response.getResult().getOutput().getText(); System.out.println("Answer: " + answer); ---- TIP: Thinking-capable models in Ollama (0.12+) automatically enable thinking mode when accessed through the OpenAI-compatible endpoint. The reasoning content is captured automatically without requiring additional configuration. Check 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. == HuggingFace Models Ollama can access, out of the box, all https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face ] Chat Models. You can pull any of these models by name: `ollama pull hf.co//` or configure the auto-pulling strategy: xref:auto-pulling-models[Auto-pulling Models]: [source] ---- spring.ai.ollama.chat.options.model=hf.co/bartowski/gemma-2-2b-it-GGUF spring.ai.ollama.init.pull-model-strategy=always ---- - `spring.ai.ollama.chat.options.model`: Specifies the https://huggingface.co/models?library=gguf&sort=trending[Hugging Face GGUF model] to use. - `spring.ai.ollama.init.pull-model-strategy=always`: (optional) Enables automatic model pulling at startup time. For production, you should pre-download the models to avoid delays: `ollama pull hf.co/bartowski/gemma-2-2b-it-GGUF`. == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-ollama` to your pom (or gradle) dependencies. Add a `application.yaml` file, under the `src/main/resources` directory, to enable and configure the Ollama chat model: [source,yaml] ---- spring: ai: ollama: base-url: http://localhost:11434 chat: options: model: mistral temperature: 0.7 ---- TIP: Replace the `base-url` with your Ollama server URL. This will create an `OllamaChatModel` implementation that you can inject into your classes. Here is an example of a simple `@RestController` class that uses the chat model for text generations. [source,java] ---- @RestController public class ChatController { private final OllamaChatModel chatModel; @Autowired public ChatController(OllamaChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- == Manual Configuration If you don't want to use the Spring Boot auto-configuration, you can manually configure the `OllamaChatModel` in your application. The 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 <> to connect to the Ollama service. To use it, add the `spring-ai-ollama` dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files: [tabs] ====== Maven:: + [source,xml] ---- org.springframework.ai spring-ai-ollama ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-ollama' } ---- ====== TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. TIP: The `spring-ai-ollama` dependency provides access also to the `OllamaEmbeddingModel`. For more information about the `OllamaEmbeddingModel` refer to the link:../embeddings/ollama-embeddings.html[Ollama Embedding Model] section. Next, create an `OllamaChatModel` instance and use it to send requests for text generation: [source,java] ---- var ollamaApi = OllamaApi.builder().build(); var chatModel = OllamaChatModel.builder() .ollamaApi(ollamaApi) .defaultOptions( OllamaChatOptions.builder() .model(OllamaModel.MISTRAL) .temperature(0.9) .build()) .build(); ChatResponse response = this.chatModel.call( new Prompt("Generate the names of 5 famous pirates.")); // Or with streaming responses Flux response = this.chatModel.stream( new Prompt("Generate the names of 5 famous pirates.")); ---- The `OllamaChatOptions` provides the configuration information for all chat requests. == Low-level OllamaApi Client [[low-level-api]] The 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]. The following class diagram illustrates the `OllamaApi` chat interfaces and building blocks: image::ollama-chat-completion-api.jpg[OllamaApi Chat Completion API Diagram, 800, 600] NOTE: The `OllamaApi` is a low-level API and is not recommended for direct use. Use the `OllamaChatModel` instead. Here is a simple snippet showing how to use the API programmatically: [source,java] ---- OllamaApi ollamaApi = new OllamaApi("YOUR_HOST:YOUR_PORT"); // Sync request var request = ChatRequest.builder("orca-mini") .stream(false) // not streaming .messages(List.of( Message.builder(Role.SYSTEM) .content("You are a geography teacher. You are talking to a student.") .build(), Message.builder(Role.USER) .content("What is the capital of Bulgaria and what is the size? " + "What is the national anthem?") .build())) .options(OllamaChatOptions.builder().temperature(0.9).build()) .build(); ChatResponse response = this.ollamaApi.chat(this.request); // Streaming request var request2 = ChatRequest.builder("orca-mini") .ttream(true) // streaming .messages(List.of(Message.builder(Role.USER) .content("What is the capital of Bulgaria and what is the size? " + "What is the national anthem?") .build())) .options(OllamaChatOptions.builder().temperature(0.9).build().toMap()) .build(); Flux streamingResponse = this.ollamaApi.streamingChat(this.request2); ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chat/openai-chat.adoc ================================================ = OpenAI Chat Spring 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. [NOTE] ==== Starting 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]. ==== == Prerequisites You will need to create an API with OpenAI to access ChatGPT models. Create 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]. The 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. You can set this configuration property in your `application.properties` file: [source,properties] ---- spring.ai.openai.api-key= ---- For enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference a custom environment variable: [source,yaml] ---- # In application.yml spring: ai: openai: api-key: ${OPENAI_API_KEY} ---- [source,bash] ---- # In your environment or .env file export OPENAI_API_KEY= ---- You can also set this configuration programmatically in your application code: [source,java] ---- // Retrieve API key from a secure source or environment variable String apiKey = System.getenv("OPENAI_API_KEY"); ---- === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the OpenAI Chat Client. To enable it add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-openai' } ---- ====== TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Chat Properties ==== Retry Properties The prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the OpenAI chat model. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.retry.max-attempts | Maximum number of retry attempts. | 10 | spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. | 2 sec. | spring.ai.retry.backoff.multiplier | Backoff interval multiplier. | 5 | spring.ai.retry.backoff.max-interval | Maximum backoff duration. | 3 min. | spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false | spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty | spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty |==== ==== Connection Properties The prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.base-url | The URL to connect to | https://api.openai.com | spring.ai.openai.api-key | The API Key | - | spring.ai.openai.organization-id | Optionally, you can specify which organization to use for an API request. | - | spring.ai.openai.project-id | Optionally, you can specify which project to use for an API request. | - |==== TIP: 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. Usage from these API requests will count as usage for the specified organization and project. ==== User-Agent Header Spring AI automatically sends a `User-Agent: spring-ai` header with all requests to OpenAI. This helps OpenAI identify requests originating from Spring AI for analytics and support purposes. This header is sent automatically and requires no configuration from Spring AI users. If 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. ==== Configuration Properties [NOTE] ==== Enabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`. To enable, spring.ai.model.chat=openai (It is enabled by default) To disable, spring.ai.model.chat=none (or any value which doesn't match openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.openai.chat` is the property prefix that lets you configure the chat model implementation for OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.chat.enabled (Removed and no longer valid) | Enable OpenAI chat model. | true | spring.ai.model.chat | Enable OpenAI chat model. | openai | spring.ai.openai.chat.base-url | Optional override for the `spring.ai.openai.base-url` property to provide a chat-specific URL. | - | spring.ai.openai.chat.completions-path | The path to append to the base URL. | `/v1/chat/completions` | spring.ai.openai.chat.api-key | Optional override for the `spring.ai.openai.api-key` to provide a chat-specific API Key. | - | spring.ai.openai.chat.organization-id | Optionally, you can specify which organization to use for an API request. | - | spring.ai.openai.chat.project-id | Optionally, you can specify which project to use for an API request. | - | 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` | 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 | 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 | spring.ai.openai.chat.options.logitBias | Modify the likelihood of specified tokens appearing in the completion. | - | 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. | - | 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. | - | 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 | spring.ai.openai.chat.options.store | Whether to store the output of this chat completion request for use in our model | false | spring.ai.openai.chat.options.metadata | Developer-defined tags and values used for filtering completions in the chat completion dashboard | empty map | 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. The `gpt-4o-audio-preview` model can also be used to generate audio. To request that this model generate both text and audio responses, you can use: `text`, `audio`. Not supported for streaming. | - | spring.ai.openai.chat.options.output-audio | Audio parameters for the audio generation. Required when audio output is requested with `output-modalities`: `audio`. Requires the `gpt-4o-audio-preview` model and is is not supported for streaming completions. | - | 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. | - | 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. The `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. | - | spring.ai.openai.chat.options.responseFormat.name | Response format schema name. Applicable only for `responseFormat.type=JSON_SCHEMA` | custom_schema | spring.ai.openai.chat.options.responseFormat.schema | Response format JSON schema. Applicable only for `responseFormat.type=JSON_SCHEMA` | - | spring.ai.openai.chat.options.responseFormat.strict | Response format JSON schema adherence strictness. Applicable only for `responseFormat.type=JSON_SCHEMA` | - | 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. | - | spring.ai.openai.chat.options.stop | Up to 4 sequences where the API will stop generating further tokens. | - | 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. | - | 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. | - | 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. | - | spring.ai.openai.chat.options.user | A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. | - | 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 | 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 | 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]. | - | 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]. | - | 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. | - | 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. | - | spring.ai.openai.chat.options.tool-callbacks | Tool Callbacks to register with the ChatModel. | - | 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 | 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. | - | 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 <> for details. | - |==== [NOTE] ==== When using GPT-5 models such as `gpt-5`, `gpt-5-mini`, and `gpt-5-nano`, the `temperature` parameter is not supported. These models are optimized for reasoning and do not use temperature. Specifying a temperature value will result in an error. In contrast, conversational models like `gpt-5-chat` do support the `temperature` parameter. ==== NOTE: You can override the common `spring.ai.openai.base-url` and `spring.ai.openai.api-key` for the `ChatModel` and `EmbeddingModel` implementations. The `spring.ai.openai.chat.base-url` and `spring.ai.openai.chat.api-key` properties, if set, take precedence over the common properties. This is useful if you want to use different OpenAI accounts for different models and different model endpoints. TIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding request-specific <> to the `Prompt` call. === Token Limit Parameters: Model-Specific Usage OpenAI provides two mutually exclusive parameters for controlling token generation limits: [cols="2,3,3", stripes=even] |==== | Parameter | Use Case | Compatible Models | `maxTokens` | Non-reasoning models | gpt-4o, gpt-4o-mini, gpt-4-turbo, gpt-3.5-turbo | `maxCompletionTokens` | Reasoning models | o1, o1-mini, o1-preview, o3, o4-mini series |==== IMPORTANT: These parameters are **mutually exclusive**. Setting both will result in an API error from OpenAI. ==== Usage Examples **For non-reasoning models (gpt-4o, gpt-3.5-turbo):** [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Explain quantum computing in simple terms.", OpenAiChatOptions.builder() .model("gpt-4o") .maxTokens(150) // Use maxTokens for non-reasoning models .build() )); ---- **For reasoning models (o1, o3 series):** [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Solve this complex math problem step by step: ...", OpenAiChatOptions.builder() .model("o1-preview") .maxCompletionTokens(1000) // Use maxCompletionTokens for reasoning models .build() )); ---- **Builder Pattern Validation:** The OpenAI ChatOptions builder automatically enforces mutual exclusivity with a "last-set-wins" approach: [source,java] ---- // This will automatically clear maxTokens and use maxCompletionTokens OpenAiChatOptions options = OpenAiChatOptions.builder() .maxTokens(100) // Set first .maxCompletionTokens(200) // This clears maxTokens and logs a warning .build(); // Result: maxTokens = null, maxCompletionTokens = 200 ---- == Runtime Options [[chat-options]] The 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. On start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties. At run-time, you can override the default options by adding new, request-specific options to the `Prompt` call. For example, to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", OpenAiChatOptions.builder() .model("gpt-4o") .temperature(0.4) .build() )); ---- TIP: 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()]. == Function Calling You 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. This is a powerful technique to connect the LLM capabilities with external tools and APIs. Read more about xref:api/tools.adoc[Tool Calling]. == Multimodal Multimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats. OpenAI supports text, vision, and audio input modalities. === Vision OpenAI models that offer vision multimodal support include `gpt-4`, `gpt-4o`, and `gpt-4o-mini`. Refer to the link:https://platform.openai.com/docs/guides/vision[Vision] guide for more information. The 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. Spring 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. This 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. Below 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. [source,java] ---- var imageResource = new ClassPathResource("/multimodal.test.png"); var userMessage = new UserMessage("Explain what do you see on this picture?", new Media(MimeTypeUtils.IMAGE_PNG, this.imageResource)); ChatResponse response = chatModel.call(new Prompt(this.userMessage, OpenAiChatOptions.builder().model(OpenAiApi.ChatModel.GPT_4_O.getValue()).build())); ---- TIP: 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] or the image URL equivalent using the `gpt-4o` model: [source,java] ---- var userMessage = new UserMessage("Explain what do you see on this picture?", new Media(MimeTypeUtils.IMAGE_PNG, URI.create("https://docs.spring.io/spring-ai/reference/_images/multimodal.test.png"))); ChatResponse response = chatModel.call(new Prompt(this.userMessage, OpenAiChatOptions.builder().model(OpenAiApi.ChatModel.GPT_4_O.getValue()).build())); ---- TIP: You can pass multiple images as well. The example shows a model taking as an input the `multimodal.test.png` image: image::multimodal.test.png[Multimodal Test Image, 200, 200, align="left"] along with the text message "Explain what do you see on this picture?", and generating a response like this: ---- This is an image of a fruit bowl with a simple design. The bowl is made of metal with curved wire edges that create an open structure, allowing the fruit to be visible from all angles. Inside the bowl, there are two yellow bananas resting on top of what appears to be a red apple. The bananas are slightly overripe, as indicated by the brown spots on their peels. The bowl has a metal ring at the top, likely to serve as a handle for carrying. The bowl is placed on a flat surface with a neutral-colored background that provides a clear view of the fruit inside. ---- === Audio OpenAI models that offer input audio multimodal support include `gpt-4o-audio-preview`. Refer to the link:https://platform.openai.com/docs/guides/audio[Audio] guide for more information. The 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. Spring 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. This 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. Currently, OpenAI support only the following media types: `audio/mp3` and `audio/wav`. Below 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. [source,java] ---- var audioResource = new ClassPathResource("speech1.mp3"); var userMessage = new UserMessage("What is this recording about?", List.of(new Media(MimeTypeUtils.parseMimeType("audio/mp3"), audioResource))); ChatResponse response = chatModel.call(new Prompt(List.of(userMessage), OpenAiChatOptions.builder().model(OpenAiApi.ChatModel.GPT_4_O_AUDIO_PREVIEW).build())); ---- TIP: You can pass multiple audio files as well. === Output Audio OpenAI models that offer input audio multimodal support include `gpt-4o-audio-preview`. Refer to the link:https://platform.openai.com/docs/guides/audio[Audio] guide for more information. The 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. Spring 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. This 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. Currently, OpenAI support only the following audio types: `audio/mp3` and `audio/wav`. Below is a code example, illustrating the response of user text along with an audio byte array, using the `gpt-4o-audio-preview` model: [source,java] ---- var userMessage = new UserMessage("Tell me joke about Spring Framework"); ChatResponse response = chatModel.call(new Prompt(List.of(userMessage), OpenAiChatOptions.builder() .model(OpenAiApi.ChatModel.GPT_4_O_AUDIO_PREVIEW) .outputModalities(List.of("text", "audio")) .outputAudio(new AudioParameters(Voice.ALLOY, AudioResponseFormat.WAV)) .build())); String text = response.getResult().getOutput().getText(); // audio transcript byte[] waveAudio = response.getResult().getOutput().getMedia().get(0).getDataAsByteArray(); // audio data ---- You have to specify an `audio` modality in the `OpenAiChatOptions` to generate audio output. The `AudioParameters` class provides the voice and audio format for the audio output. == Structured Outputs OpenAI 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`. In addition to the existing Spring AI model-agnostic xref::api/structured-output-converter.adoc[Structured Output Converter], these APIs offer enhanced control and precision. NOTE: Currently, OpenAI supports a link:https://platform.openai.com/docs/guides/structured-outputs/supported-schemas[subset of the JSON Schema language] format. === Configuration Spring AI allows you to configure your response format either programmatically using the `OpenAiChatOptions` builder or through application properties. ==== Using the Chat Options Builder You can set the response format programmatically with the `OpenAiChatOptions` builder as shown below: [source,java] ---- String jsonSchema = """ { "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 } """; Prompt prompt = new Prompt("how can I solve 8x + 7 = -23", OpenAiChatOptions.builder() .model(ChatModel.GPT_4_O_MINI) .responseFormat(new ResponseFormat(ResponseFormat.Type.JSON_SCHEMA, this.jsonSchema)) .build()); ChatResponse response = this.openAiChatModel.call(this.prompt); ---- NOTE: Adhere to the OpenAI link:https://platform.openai.com/docs/guides/structured-outputs/supported-schemas[subset of the JSON Schema language] format. ==== Integrating with BeanOutputConverter Utilities You 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: -- [tabs] ====== Java:: + [source,java] ---- record MathReasoning( @JsonProperty(required = true, value = "steps") Steps steps, @JsonProperty(required = true, value = "final_answer") String finalAnswer) { record Steps( @JsonProperty(required = true, value = "items") Items[] items) { record Items( @JsonProperty(required = true, value = "explanation") String explanation, @JsonProperty(required = true, value = "output") String output) { } } } var outputConverter = new BeanOutputConverter<>(MathReasoning.class); var jsonSchema = this.outputConverter.getJsonSchema(); Prompt prompt = new Prompt("how can I solve 8x + 7 = -23", OpenAiChatOptions.builder() .model(ChatModel.GPT_4_O_MINI) .responseFormat(new ResponseFormat(ResponseFormat.Type.JSON_SCHEMA, this.jsonSchema)) .build()); ChatResponse response = this.openAiChatModel.call(this.prompt); String content = this.response.getResult().getOutput().getText(); MathReasoning mathReasoning = this.outputConverter.convert(this.content); ---- Kotlin:: + [source,kotlin] ---- data class MathReasoning( val steps: Steps, @get:JsonProperty(value = "final_answer") val finalAnswer: String) { data class Steps(val items: Array) { data class Items( val explanation: String, val output: String) } } val outputConverter = BeanOutputConverter(MathReasoning::class.java) val jsonSchema = outputConverter.jsonSchema; val prompt = Prompt("how can I solve 8x + 7 = -23", OpenAiChatOptions.builder() .model(ChatModel.GPT_4_O_MINI) .responseFormat(ResponseFormat(ResponseFormat.Type.JSON_SCHEMA, jsonSchema)) .build()) val response = openAiChatModel.call(prompt) val content = response.getResult().getOutput().getText() val mathReasoning = outputConverter.convert(content) ---- ====== -- NOTE: 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]. ==== Configuring via Application Properties Alternatively, when using the OpenAI auto-configuration, you can configure the desired response format through the following application properties: [source,application.properties] ---- spring.ai.openai.api-key=YOUR_API_KEY spring.ai.openai.chat.options.model=gpt-4o-mini spring.ai.openai.chat.options.response-format.type=JSON_SCHEMA spring.ai.openai.chat.options.response-format.name=MySchemaName spring.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} spring.ai.openai.chat.options.response-format.strict=true ---- == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies. Add an `application.properties` file under the `src/main/resources` directory to enable and configure the OpenAi chat model: [source,application.properties] ---- spring.ai.openai.api-key=YOUR_API_KEY spring.ai.openai.chat.options.model=gpt-4o spring.ai.openai.chat.options.temperature=0.7 ---- TIP: Replace the `api-key` with your OpenAI credentials. This will create an `OpenAiChatModel` implementation that you can inject into your classes. Here is an example of a simple `@RestController` class that uses the chat model for text generations. [source,java] ---- @RestController public class ChatController { private final OpenAiChatModel chatModel; @Autowired public ChatController(OpenAiChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- == Manual Configuration The 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 <> to connect to the OpenAI service. Add the `spring-ai-openai` dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-openai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Next, create an `OpenAiChatModel` and use it for text generations: [source,java] ---- var openAiApi = OpenAiApi.builder() .apiKey(System.getenv("OPENAI_API_KEY")) .build(); var openAiChatOptions = OpenAiChatOptions.builder() .model("gpt-3.5-turbo") .temperature(0.4) .maxTokens(200) .build(); var chatModel = new OpenAiChatModel(this.openAiApi, this.openAiChatOptions); ChatResponse response = this.chatModel.call( new Prompt("Generate the names of 5 famous pirates.")); // Or with streaming responses Flux response = this.chatModel.stream( new Prompt("Generate the names of 5 famous pirates.")); ---- The `OpenAiChatOptions` provides the configuration information for the chat requests. The `OpenAiApi.Builder` and `OpenAiChatOptions.Builder` are fluent options-builders for API client and chat config respectively. == Low-level OpenAiApi Client [[low-level-api]] The 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 Chat API link:https://platform.openai.com/docs/api-reference/chat[OpenAI Chat API]. Following class diagram illustrates the `OpenAiApi` chat interfaces and building blocks: image::openai-chat-api.jpg[OpenAiApi Chat API Diagram, width=1000, align="center"] Here is a simple snippet showing how to use the API programmatically: [source,java] ---- OpenAiApi openAiApi = OpenAiApi.builder() .apiKey(System.getenv("OPENAI_API_KEY")) .build(); ChatCompletionMessage chatCompletionMessage = new ChatCompletionMessage("Hello world", Role.USER); // Sync request ResponseEntity response = this.openAiApi.chatCompletionEntity( new ChatCompletionRequest(List.of(this.chatCompletionMessage), "gpt-3.5-turbo", 0.8, false)); // Streaming request Flux streamResponse = this.openAiApi.chatCompletionStream( new ChatCompletionRequest(List.of(this.chatCompletionMessage), "gpt-3.5-turbo", 0.8, true)); ---- Follow the 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. === Low-level API Examples * 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 provide some general examples of how to use the lightweight library. * The link:https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/api/tool/OpenAiApiToolFunctionCallIT.java[OpenAiApiToolFunctionCallIT.java] tests show how to use the low-level API to call tool functions. Based on the link:https://platform.openai.com/docs/guides/function-calling/parallel-function-calling[OpenAI Function Calling] tutorial. == Low-level OpenAiFileApi Client [[low-level-file-api]] The 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] Here is a simple snippet showing how to use the API programmatically: [source,java] ---- OpenAiFileApi openAiFileApi = OpenAiFileApi.builder() .apiKey(new SimpleApiKey(System.getenv("OPENAI_API_KEY"))) .build(); // Upload a file byte[] fileBytes = Files.readAllBytes(Paths.get("evals.jsonl")); OpenAiFileApi.UploadFileRequest uploadRequest = OpenAiFileApi.UploadFileRequest.builder() .file(fileBytes) .fileName("evals-data.jsonl") .purpose(OpenAiFileApi.Purpose.EVALS) .build(); ResponseEntity uploadResponse = openAiFileApi.uploadFile(uploadRequest); // List files OpenAiFileApi.ListFileRequest listRequest = OpenAiFileApi.ListFileRequest.builder() .purpose(OpenAiFileApi.Purpose.EVALS) .build(); ResponseEntity listResponse = openAiFileApi.listFiles(listRequest); // Retrieve file information ResponseEntity fileInfo = openAiFileApi.retrieveFile("file-id"); // Delete a file ResponseEntity deleteResponse = openAiFileApi.deleteFile("file-id"); // Retrieve file content ResponseEntity fileContent = openAiFileApi.retrieveFileContent("file-id"); ---- === Low-level File API Examples * 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. == API Key Management Spring 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. === Default Configuration By default, Spring Boot auto-configuration will create an API key bean using the `spring.ai.openai.api-key` property: [source,properties] ---- spring.ai.openai.api-key=your-api-key-here ---- === Custom API Key Configuration You can create a custom instance of `OpenAiApi` with your own `ApiKey` implementation using the builder pattern: [source,java] ---- ApiKey customApiKey = new ApiKey() { @Override public String getValue() { // Custom logic to retrieve API key return "your-api-key-here"; } }; OpenAiApi openAiApi = OpenAiApi.builder() .apiKey(customApiKey) .build(); // Create a chat model with the custom OpenAiApi instance OpenAiChatModel chatModel = OpenAiChatModel.builder() .openAiApi(openAiApi) .build(); // Build the ChatClient using the custom chat model ChatClient openAiChatClient = ChatClient.builder(chatModel).build(); ---- This is useful when you need to: * Retrieve the API key from a secure key store * Rotate API keys dynamically * Implement custom API key selection logic == Using Extra Parameters with OpenAI-Compatible Servers [[openai-compatible-servers]] OpenAI-compatible inference servers like vLLM, Ollama, and others often support additional parameters beyond those defined in OpenAI's standard API. For example, these servers may accept parameters such as `top_k`, `repetition_penalty`, or other sampling controls that the official OpenAI API does not recognize. The `extraBody` option allows you to pass arbitrary parameters to these servers. Any 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. [IMPORTANT] ==== The `extraBody` parameter is intended for use with OpenAI-compatible servers, not the official OpenAI API. The official OpenAI API applies strict validation and will return an HTTP 400 error (`"Unknown parameter: 'extra_body'"`) if unrecognized fields are encountered. If you are communicating with the official OpenAI API, you should **never** populate the `extraBody` parameter. Also 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. ==== === Configuration with Properties You can configure extra parameters using Spring Boot properties. Each property under `spring.ai.openai.chat.options.extra-body` becomes a top-level parameter in the request: [source,properties] ---- spring.ai.openai.base-url=http://localhost:8000 spring.ai.openai.chat.options.model=meta-llama/Llama-3-8B-Instruct spring.ai.openai.chat.options.temperature=0.7 spring.ai.openai.chat.options.extra-body.top_k=50 spring.ai.openai.chat.options.extra-body.repetition_penalty=1.1 ---- This configuration would produce a JSON request like: [source,json] ---- { "model": "meta-llama/Llama-3-8B-Instruct", "temperature": 0.7, "top_k": 50, "repetition_penalty": 1.1, "messages": [...] } ---- === Runtime Configuration with Builder You can also specify extra parameters at runtime using the options builder: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Tell me a creative story", OpenAiChatOptions.builder() .model("meta-llama/Llama-3-8B-Instruct") .temperature(0.7) .extraBody(Map.of( "top_k", 50, "repetition_penalty", 1.1, "frequency_penalty", 0.5 )) .build() )); ---- === Example: vLLM Server When running vLLM with a Llama model, you might want to use sampling parameters specific to vLLM: [source,properties] ---- spring.ai.openai.base-url=http://localhost:8000 spring.ai.openai.chat.options.model=meta-llama/Llama-3-70B-Instruct spring.ai.openai.chat.options.extra-body.top_k=40 spring.ai.openai.chat.options.extra-body.top_p=0.95 spring.ai.openai.chat.options.extra-body.repetition_penalty=1.05 spring.ai.openai.chat.options.extra-body.min_p=0.05 ---- Refer to the link:https://docs.vllm.ai/en/latest/[vLLM documentation] for a complete list of supported sampling parameters. === Example: Ollama Server When using Ollama through the OpenAI-compatible endpoint, you can pass Ollama-specific parameters: [source,java] ---- OpenAiChatOptions options = OpenAiChatOptions.builder() .model("llama3.2") .extraBody(Map.of( "num_predict", 100, "top_k", 40, "repeat_penalty", 1.1 )) .build(); ChatResponse response = chatModel.call(new Prompt("Generate text", options)); ---- Consult the link:https://github.com/ollama/ollama/blob/main/docs/api.md[Ollama API documentation] for available parameters. [NOTE] ==== The `extraBody` parameter accepts any `Map`, allowing you to pass whatever parameters your target server supports. Spring AI does not validate these parameters—they are passed directly to the server. This design provides maximum flexibility for working with diverse OpenAI-compatible implementations. ==== === Reasoning Content from Reasoning Models Some 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. This field contains the step-by-step reasoning process the model used to arrive at its final answer. Spring AI maps this field from the JSON response to the `reasoningContent` key in the AssistantMessage metadata. [IMPORTANT] ==== **Important distinction about `reasoning_content` availability:** * **OpenAI-compatible servers** (DeepSeek, vLLM): Expose `reasoning_content` in Chat Completions API responses ✅ * **Official OpenAI models** (GPT-5, o1, o3): Do **NOT** expose reasoning text in Chat Completions API responses ❌ Official OpenAI reasoning models hide the chain-of-thought content when using the Chat Completions API. They only expose `reasoning_tokens` count in usage statistics. To access actual reasoning text from official OpenAI models, you must use OpenAI's Responses API (a separate endpoint not currently supported by this client). **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. ==== ==== Accessing Reasoning Content When using a compatible server, you can access the reasoning content from the response metadata. **Using ChatModel directly:** [source,java] ---- // Configure to use DeepSeek R1 or vLLM with a reasoning model ChatResponse response = chatModel.call( new Prompt("Which number is larger: 9.11 or 9.8?") ); // Get the assistant message AssistantMessage message = response.getResult().getOutput(); // Access the reasoning content from metadata String reasoning = message.getMetadata().get("reasoningContent"); if (reasoning != null && !reasoning.isEmpty()) { System.out.println("Model's reasoning process:"); System.out.println(reasoning); } // The final answer is in the regular content System.out.println("\nFinal answer:"); System.out.println(message.getContent()); ---- **Using ChatClient:** [source,java] ---- ChatClient chatClient = ChatClient.create(chatModel); String result = chatClient.prompt() .user("Which number is larger: 9.11 or 9.8?") .call() .chatResponse() .getResult() .getOutput() .getContent(); // To access reasoning content with ChatClient, retrieve the full response ChatResponse response = chatClient.prompt() .user("Which number is larger: 9.11 or 9.8?") .call() .chatResponse(); AssistantMessage message = response.getResult().getOutput(); String reasoning = message.getMetadata().get("reasoningContent"); ---- ==== Streaming Reasoning Content When using streaming responses, reasoning content is accumulated across chunks just like regular message content: [source,java] ---- Flux responseFlux = chatModel.stream( new Prompt("Solve this logic puzzle...") ); StringBuilder reasoning = new StringBuilder(); StringBuilder answer = new StringBuilder(); responseFlux.subscribe(chunk -> { AssistantMessage message = chunk.getResult().getOutput(); // Accumulate reasoning if present String reasoningChunk = message.getMetadata().get("reasoningContent"); if (reasoningChunk != null) { reasoning.append(reasoningChunk); } // Accumulate the final answer if (message.getContent() != null) { answer.append(message.getContent()); } }); ---- ==== Example: DeepSeek R1 DeepSeek R1 is a reasoning model that exposes its internal reasoning process: [source,properties] ---- spring.ai.openai.api-key=${DEEPSEEK_API_KEY} spring.ai.openai.base-url=https://api.deepseek.com spring.ai.openai.chat.options.model=deepseek-reasoner ---- When you make requests to DeepSeek R1, responses will include both the reasoning content (the model's thought process) and the final answer. Refer to the link:https://api-docs.deepseek.com/guides/reasoning_model[DeepSeek API documentation] for more details on reasoning models. ==== Example: vLLM with Reasoning Parser vLLM supports reasoning models when configured with a reasoning parser: [source,bash] ---- vllm serve deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B \ --enable-reasoning \ --reasoning-parser deepseek_r1 ---- [source,properties] ---- spring.ai.openai.base-url=http://localhost:8000 spring.ai.openai.chat.options.model=deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B ---- Consult the link:https://docs.vllm.ai/en/latest/features/reasoning_outputs.html[vLLM reasoning outputs documentation] for supported reasoning models and parsers. [NOTE] ==== The availability of `reasoning_content` depends entirely on the inference server you're using. Not all OpenAI-compatible servers expose reasoning content, even when using reasoning-capable models. Always refer to your server's API documentation to understand what fields are available in responses. ==== ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chat/perplexity-chat.adoc ================================================ = Perplexity Chat https://perplexity.ai/[Perplexity AI] provides a unique AI service that integrates its language models with real-time search capabilities. It offers a variety of models and supports streaming responses for conversational AI. Spring AI integrates with Perplexity AI by reusing the existing xref::api/chat/openai-chat.adoc[OpenAI] client. To get started, you'll need to obtain a https://docs.perplexity.ai/guides/getting-started[Perplexity API Key], configure the base URL, and select one of the supported https://docs.perplexity.ai/guides/model-cards[models]. image::spring-ai-perplexity-integration.jpg[w=800,align="center"] NOTE: The Perplexity API is not fully compatible with the OpenAI API. Perplexity combines realtime web search results with its language model responses. Unlike OpenAI, Perplexity does not expose `toolCalls` - `function call` mechanisms. Additionally, currently Perplexity doesn’t support multimodal messages. Check the https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/chat/proxy/PerplexityWithOpenAiChatModelIT.java[PerplexityWithOpenAiChatModelIT.java] tests for examples of using Perplexity with Spring AI. == Prerequisites * **Create an API Key**: Visit https://docs.perplexity.ai/guides/getting-started[here] to create an API Key. Configure it using the `spring.ai.openai.api-key` property in your Spring AI project. * **Set the Perplexity Base URL**: Set the `spring.ai.openai.base-url` property to `+https://api.perplexity.ai+`. * **Select a Perplexity Model**: Use the `spring.ai.openai.chat.model=` property to specify the model. Refer to https://docs.perplexity.ai/guides/model-cards[Supported Models] for available options. * **Set the chat completions path**: Set the `spring.ai.openai.chat.completions-path` to `/chat/completions`. Refer to https://docs.perplexity.ai/api-reference/chat-completions[chat completions api] for more details. You can set these configuration properties in your `application.properties` file: [source,properties] ---- spring.ai.openai.api-key= spring.ai.openai.base-url=https://api.perplexity.ai spring.ai.openai.chat.model=llama-3.1-sonar-small-128k-online spring.ai.openai.chat.completions-path=/chat/completions ---- For enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference custom environment variables: [source,yaml] ---- # In application.yml spring: ai: openai: api-key: ${PERPLEXITY_API_KEY} base-url: ${PERPLEXITY_BASE_URL} chat: model: ${PERPLEXITY_MODEL} completions-path: ${PERPLEXITY_COMPLETIONS_PATH} ---- [source,bash] ---- # In your environment or .env file export PERPLEXITY_API_KEY= export PERPLEXITY_BASE_URL=https://api.perplexity.ai export PERPLEXITY_MODEL=llama-3.1-sonar-small-128k-online export PERPLEXITY_COMPLETIONS_PATH=/chat/completions ---- You can also set these configurations programmatically in your application code: [source,java] ---- // Retrieve configuration from secure sources or environment variables String apiKey = System.getenv("PERPLEXITY_API_KEY"); String baseUrl = System.getenv("PERPLEXITY_BASE_URL"); String model = System.getenv("PERPLEXITY_MODEL"); String completionsPath = System.getenv("PERPLEXITY_COMPLETIONS_PATH"); ---- === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the OpenAI Chat Client. To enable it add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-openai' } ---- ====== TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Chat Properties ==== Retry Properties The prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the OpenAI chat model. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.retry.max-attempts | Maximum number of retry attempts. | 10 | spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. | 2 sec. | spring.ai.retry.backoff.multiplier | Backoff interval multiplier. | 5 | spring.ai.retry.backoff.max-interval | Maximum backoff duration. | 3 min. | spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false | spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty | spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty |==== ==== Connection Properties The prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.base-url | The URL to connect to. Must be set to `+https://api.perplexity.ai+` | - | spring.ai.openai.chat.api-key | Your Perplexity API Key | - |==== ==== Configuration Properties [NOTE] ==== Enabling and disabling of the chat auto-configurations are now configured via top level properties with the prefix `spring.ai.model.chat`. To enable, spring.ai.model.chat=openai (It is enabled by default) To disable, spring.ai.model.chat=none (or any value which doesn't match openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.openai.chat` is the property prefix that lets you configure the chat model implementation for OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.model.chat | Enable OpenAI chat model. | openai | spring.ai.openai.chat.model | One of the supported https://docs.perplexity.ai/guides/model-cards[Perplexity models]. Example: `llama-3.1-sonar-small-128k-online`. | - | spring.ai.openai.chat.base-url | Optional overrides the spring.ai.openai.base-url to provide chat specific url. Must be set to `+https://api.perplexity.ai+` | - | spring.ai.openai.chat.completions-path | Must be set to `/chat/completions` | `/v1/chat/completions` | spring.ai.openai.chat.options.temperature | The amount of randomness in the response, valued between 0 inclusive and 2 exclusive. Higher values are more random, and lower values are more deterministic. Required range: `0 < x < 2`. | 0.2 | spring.ai.openai.chat.options.frequencyPenalty | A multiplicative penalty greater than 0. Values greater than 1.0 penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim. A value of 1.0 means no penalty. Incompatible with presence_penalty. Required range: `x > 0`. | 1 | spring.ai.openai.chat.options.maxTokens | The maximum number of completion tokens returned by the API. The total number of tokens requested in max_tokens plus the number of prompt tokens sent in messages must not exceed the context window token limit of model requested. If left unspecified, then the model will generate tokens until either it reaches its stop token or the end of its context window. | - | spring.ai.openai.chat.options.presencePenalty | A value 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. Incompatible with `frequency_penalty`. Required range: `-2 < x < 2` | 0 | spring.ai.openai.chat.options.topP | The nucleus sampling threshold, valued between 0 and 1 inclusive. 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 | 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 |==== TIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding a request specific <> to the `Prompt` call. == Runtime Options [[chat-options]] The 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. On start-up, the default options can be configured with the `OpenAiChatModel(api, options)` constructor or the `spring.ai.openai.chat.options.*` properties. At run-time you can override the default options by adding new, request specific, options to the `Prompt` call. For example to override the default model and temperature for a specific request: [source,java] ---- ChatResponse response = chatModel.call( new Prompt( "Generate the names of 5 famous pirates.", OpenAiChatOptions.builder() .model("llama-3.1-sonar-large-128k-online") .temperature(0.4) .build() )); ---- TIP: 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()]. == Function Calling NOTE: Perplexity does not support explicit function calling. Instead, it integrates search results directly into responses. == Multimodal NOTE: Currently, the Perplexity API doesn't support media content. == Sample Controller https://start.spring.io/[Create] a new Spring Boot project and add the `spring-ai-starter-model-openai` to your pom (or gradle) dependencies. Add a `application.properties` file, under the `src/main/resources` directory, to enable and configure the OpenAi chat model: [source,application.properties] ---- spring.ai.openai.api-key= spring.ai.openai.base-url=https://api.perplexity.ai spring.ai.openai.chat.completions-path=/chat/completions spring.ai.openai.chat.options.model=llama-3.1-sonar-small-128k-online spring.ai.openai.chat.options.temperature=0.7 # The Perplexity API doesn't support embeddings, so we need to disable it. spring.ai.openai.embedding.enabled=false ---- TIP: replace the `api-key` with your Perplexity Api key. This will create a `OpenAiChatModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the chat model for text generations. [source,java] ---- @RestController public class ChatController { private final OpenAiChatModel chatModel; @Autowired public ChatController(OpenAiChatModel chatModel) { this.chatModel = chatModel; } @GetMapping("/ai/generate") public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("generation", this.chatModel.call(message)); } @GetMapping("/ai/generateStream") public Flux generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { Prompt prompt = new Prompt(new UserMessage(message)); return this.chatModel.stream(prompt); } } ---- == Supported Models Perplexity supports several models optimized for search-enhanced conversational AI.

The 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]. The 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]. == 1. Configuration The configuration section outlines how to set up and tune your Large Language Model (LLM) with Spring AI. It 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. === LLM Provider Selection For prompt engineering, you will start by choosing a model. Spring 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. Just add the selected starter dependency `spring-ai-starter-model-`. For example, here is how to enable Anthropic Claude API: [source,xml] ---- org.springframework.ai spring-ai-starter-model-anthropic ---- You can specify the LLM model name like this: [source,java] ---- .options(ChatOptions.builder() .model("claude-sonnet-4-6") // Use Anthropic's Claude model .build()) ---- Find detailed information for enabling each model in the xref::api/chatmodel.adoc[reference docs]. === LLM Output Configuration image::https://docs.spring.io/spring-ai/reference/_images/chat-options-flow.jpg[width=500,float=right] Before 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. All configurations can be applied programmatically as demonstrated in the examples below or through Spring application properties at start time. ==== Temperature Temperature controls the randomness or "creativity" of the model's response. * *Lower values (0.0-0.3)*: More deterministic, focused responses. Better for factual questions, classification, or tasks where consistency is critical. * *Medium values (0.4-0.7)*: Balanced between determinism and creativity. Good for general use cases. * *Higher values (0.8-1.0)*: More creative, varied, and potentially surprising responses. Better for creative writing, brainstorming, or generating diverse options. [source,java] ---- .options(ChatOptions.builder() .temperature(0.1) // Very deterministic output .build()) ---- Understanding temperature is crucial for prompt engineering as different techniques benefit from different temperature settings. ==== Output Length (MaxTokens) The `maxTokens` parameter limits how many tokens (word pieces) the model can generate in its response. * *Low values (5-25)*: For single words, short phrases, or classification labels. * *Medium values (50-500)*: For paragraphs or short explanations. * *High values (1000+)*: For long-form content, stories, or complex explanations. [source,java] ---- .options(ChatOptions.builder() .maxTokens(250) // Medium-length response .build()) ---- Setting appropriate output length is important to ensure you get complete responses without unnecessary verbosity. ==== Sampling Controls (Top-K and Top-P) These parameters give you fine-grained control over the token selection process during generation. * *Top-K*: Limits token selection to the K most likely next tokens. Higher values (e.g., 40-50) introduce more diversity. * *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. [source,java] ---- .options(ChatOptions.builder() .topK(40) // Consider only the top 40 tokens .topP(0.8) // Sample from tokens that cover 80% of probability mass .build()) ---- These sampling controls work in conjunction with temperature to shape response characteristics. ==== Structured Response Format Along with the plain text response (using `.content()`), Spring AI makes it easy to directly map LLM responses to Java objects using the `.entity()` method. [source,java] ---- enum Sentiment { POSITIVE, NEUTRAL, NEGATIVE } Sentiment result = chatClient.prompt("...") .call() .entity(Sentiment.class); ---- This feature is particularly powerful when combined with system prompts that instruct the model to return structured data. ==== Model-Specific Options While 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. [source,java] ---- // Using OpenAI-specific options OpenAiChatOptions openAiOptions = OpenAiChatOptions.builder() .model("gpt-4o") .temperature(0.2) .frequencyPenalty(0.5) // OpenAI-specific parameter .presencePenalty(0.3) // OpenAI-specific parameter .responseFormat(new ResponseFormat("json_object")) // OpenAI-specific JSON mode .seed(42) // OpenAI-specific deterministic generation .build(); String result = chatClient.prompt("...") .options(openAiOptions) .call() .content(); // Using Anthropic-specific options AnthropicChatOptions anthropicOptions = AnthropicChatOptions.builder() .model("claude-sonnet-4-6") .temperature(0.2) .topK(40) // Anthropic-specific parameter .thinking(AnthropicApi.ThinkingType.ENABLED, 1000) // Anthropic-specific thinking configuration .build(); String result = chatClient.prompt("...") .options(anthropicOptions) .call() .content(); ---- Each 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. Note 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. == 2. Prompt Engineering Techniques Each section below implements a specific prompt engineering technique from the guide. By 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. === 2.1 Zero-Shot Prompting Zero-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. Zero-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. [source,java] ---- // Implementation of Section 2.1: General prompting / zero shot (page 15) public void pt_zero_shot(ChatClient chatClient) { enum Sentiment { POSITIVE, NEUTRAL, NEGATIVE } Sentiment reviewSentiment = chatClient.prompt(""" Classify movie reviews as POSITIVE, NEUTRAL or NEGATIVE. Review: "Her" is a disturbing study revealing the direction humanity is headed if AI is allowed to keep evolving, unchecked. I wish there were more movies like this masterpiece. Sentiment: """) .options(ChatOptions.builder() .model("claude-sonnet-4-6") .temperature(0.1) .maxTokens(5) .build()) .call() .entity(Sentiment.class); System.out.println("Output: " + reviewSentiment); } ---- This 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. *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] === 2.2 One-Shot & Few-Shot Prompting Few-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. One-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. [source,java] ---- // Implementation of Section 2.2: One-shot & few-shot (page 16) public void pt_one_shot_few_shots(ChatClient chatClient) { String pizzaOrder = chatClient.prompt(""" Parse a customer's pizza order into valid JSON EXAMPLE 1: I want a small pizza with cheese, tomato sauce, and pepperoni. JSON Response: ``` { "size": "small", "type": "normal", "ingredients": ["cheese", "tomato sauce", "pepperoni"] } ``` EXAMPLE 2: Can I get a large pizza with tomato sauce, basil and mozzarella. JSON Response: ``` { "size": "large", "type": "normal", "ingredients": ["tomato sauce", "basil", "mozzarella"] } ``` Now, I would like a large pizza, with the first half cheese and mozzarella. And the other tomato sauce, ham and pineapple. """) .options(ChatOptions.builder() .model("claude-sonnet-4-6") .temperature(0.1) .maxTokens(250) .build()) .call() .content(); } ---- Few-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. *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] === 2.3 System, contextual and role prompting ==== System Prompting System 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. System 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. [source,java] ---- // Implementation of Section 2.3.1: System prompting public void pt_system_prompting_1(ChatClient chatClient) { String movieReview = chatClient .prompt() .system("Classify movie reviews as positive, neutral or negative. Only return the label in uppercase.") .user(""" Review: "Her" is a disturbing study revealing the direction humanity is headed if AI is allowed to keep evolving, unchecked. It's so disturbing I couldn't watch it. Sentiment: """) .options(ChatOptions.builder() .model("claude-sonnet-4-6") .temperature(1.0) .topK(40) .topP(0.8) .maxTokens(5) .build()) .call() .content(); } ---- System prompting is particularly powerful when combined with Spring AI's entity mapping capabilities: [source,java] ---- // Implementation of Section 2.3.1: System prompting with JSON output record MovieReviews(Movie[] movie_reviews) { enum Sentiment { POSITIVE, NEUTRAL, NEGATIVE } record Movie(Sentiment sentiment, String name) { } } MovieReviews movieReviews = chatClient .prompt() .system(""" Classify movie reviews as positive, neutral or negative. Return valid JSON. """) .user(""" Review: "Her" is a disturbing study revealing the direction humanity is headed if AI is allowed to keep evolving, unchecked. It's so disturbing I couldn't watch it. JSON Response: """) .call() .entity(MovieReviews.class); ---- System 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. *Reference:* OpenAI. (2022). "System Message." link:https://platform.openai.com/docs/guides/chat/introduction[https://platform.openai.com/docs/guides/chat/introduction] ==== Role Prompting Role 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. Role 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"). [source,java] ---- // Implementation of Section 2.3.2: Role prompting public void pt_role_prompting_1(ChatClient chatClient) { String travelSuggestions = chatClient .prompt() .system(""" I want you to act as a travel guide. I will write to you about my location and you will suggest 3 places to visit near me. In some cases, I will also give you the type of places I will visit. """) .user(""" My suggestion: "I am in Amsterdam and I want to visit only museums." Travel Suggestions: """) .call() .content(); } ---- Role prompting can be enhanced with style instructions: [source,java] ---- // Implementation of Section 2.3.2: Role prompting with style instructions public void pt_role_prompting_2(ChatClient chatClient) { String humorousTravelSuggestions = chatClient .prompt() .system(""" I want you to act as a travel guide. I will write to you about my location and you will suggest 3 places to visit near me in a humorous style. """) .user(""" My suggestion: "I am in Amsterdam and I want to visit only museums." Travel Suggestions: """) .call() .content(); } ---- This technique is particularly effective for specialized domain knowledge, achieving a consistent tone across responses, and creating more engaging, personalized interactions with users. *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] ==== Contextual Prompting Contextual 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. By 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. [source,java] ---- // Implementation of Section 2.3.3: Contextual prompting public void pt_contextual_prompting(ChatClient chatClient) { String articleSuggestions = chatClient .prompt() .user(u -> u.text(""" Suggest 3 topics to write an article about with a few lines of description of what this article should contain. Context: {context} """) .param("context", "You are writing for a blog about retro 80's arcade video games.")) .call() .content(); } ---- Spring 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. *Reference:* Liu, P., et al. (2021). "What Makes Good In-Context Examples for GPT-3?" arXiv:2101.06804. link:https://arxiv.org/abs/2101.06804[https://arxiv.org/abs/2101.06804] === 2.4 Step-Back Prompting Step-back prompting breaks complex requests into simpler steps by first acquiring background knowledge. 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. By decomposing complex problems into more manageable components and establishing foundational knowledge first, the model can provide more accurate responses to difficult questions. [source,java] ---- // Implementation of Section 2.4: Step-back prompting public void pt_step_back_prompting(ChatClient.Builder chatClientBuilder) { // Set common options for the chat client var chatClient = chatClientBuilder .defaultOptions(ChatOptions.builder() .model("claude-sonnet-4-6") .temperature(1.0) .topK(40) .topP(0.8) .maxTokens(1024) .build()) .build(); // First get high-level concepts String stepBack = chatClient .prompt(""" Based on popular first-person shooter action games, what are 5 fictional key settings that contribute to a challenging and engaging level storyline in a first-person shooter video game? """) .call() .content(); // Then use those concepts in the main task String story = chatClient .prompt() .user(u -> u.text(""" Write a one paragraph storyline for a new level of a first- person shooter video game that is challenging and engaging. Context: {step-back} """) .param("step-back", stepBack)) .call() .content(); } ---- Step-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. *Reference:* Zheng, Z., et al. (2023). "Take a Step Back: Evoking Reasoning via Abstraction in Large Language Models." arXiv:2310.06117. link:https://arxiv.org/abs/2310.06117[https://arxiv.org/abs/2310.06117] === 2.5 Chain of Thought (CoT) Chain of Thought prompting encourages the model to reason step-by-step through a problem, which improves accuracy for complex reasoning tasks. 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. CoT 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. [source,java] ---- // Implementation of Section 2.5: Chain of Thought (CoT) - Zero-shot approach public void pt_chain_of_thought_zero_shot(ChatClient chatClient) { String output = chatClient .prompt(""" When I was 3 years old, my partner was 3 times my age. Now, I am 20 years old. How old is my partner? Let's think step by step. """) .call() .content(); } // Implementation of Section 2.5: Chain of Thought (CoT) - Few-shot approach public void pt_chain_of_thought_singleshot_fewshots(ChatClient chatClient) { String output = chatClient .prompt(""" Q: When my brother was 2 years old, I was double his age. Now I am 40 years old. How old is my brother? Let's think step by step. A: When my brother was 2 years, I was 2 * 2 = 4 years old. That's an age difference of 2 years and I am older. Now I am 40 years old, so my brother is 40 - 2 = 38 years old. The answer is 38. Q: When I was 3 years old, my partner was 3 times my age. Now, I am 20 years old. How old is my partner? Let's think step by step. A: """) .call() .content(); } ---- The key phrase "Let's think step by step" triggers the model to show its reasoning process. 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. *Reference:* Wei, J., et al. (2022). "Chain-of-Thought Prompting Elicits Reasoning in Large Language Models." arXiv:2201.11903. link:https://arxiv.org/abs/2201.11903[https://arxiv.org/abs/2201.11903] === 2.6 Self-Consistency Self-consistency involves running the model multiple times and aggregating results for more reliable answers. 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. By 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. [source,java] ---- // Implementation of Section 2.6: Self-consistency public void pt_self_consistency(ChatClient chatClient) { String email = """ Hi, I have seen you use Wordpress for your website.

"""; record EmailClassification(Classification classification, String reasoning) { enum Classification { IMPORTANT, NOT_IMPORTANT } } int importantCount = 0; int notImportantCount = 0; // Run the model 5 times with the same input for (int i = 0; i < 5; i++) { EmailClassification output = chatClient .prompt() .user(u -> u.text(""" Email: {email} Classify the above email as IMPORTANT or NOT IMPORTANT.

"IMPORTANT" : "NOT IMPORTANT"; } ---- Self-consistency is particularly valuable for high-stakes decisions, complex reasoning tasks, and when you need more confident answers than a single response can provide. The trade-off is increased computational cost and latency due to multiple API calls. *Reference:* Wang, X., et al. (2022). "Self-Consistency Improves Chain of Thought Reasoning in Language Models." arXiv:2203.11171. link:https://arxiv.org/abs/2203.11171[https://arxiv.org/abs/2203.11171] === 2.7 Tree of Thoughts (ToT) Tree of Thoughts (ToT) is an advanced reasoning framework that extends Chain of Thought by exploring multiple reasoning paths simultaneously. It treats problem-solving as a search process where the model generates different intermediate steps, evaluates their promise, and explores the most promising paths. This technique is particularly powerful for complex problems with multiple possible approaches or when the solution requires exploring various alternatives before finding the optimal path. [NOTE] ==== The original "Prompt Engineering" guide doesn't provide implementation examples for ToT, likely due to its complexity. Below is a simplified example that demonstrates the core concept. ==== Game Solving ToT Example: [source,java] ---- // Implementation of Section 2.7: Tree of Thoughts (ToT) - Game solving example public void pt_tree_of_thoughts_game(ChatClient chatClient) { // Step 1: Generate multiple initial moves String initialMoves = chatClient .prompt(""" You are playing a game of chess.

This meta-technique leverages the language model itself to create, refine, and benchmark different prompt variations to find optimal formulations for specific tasks. By systematically generating and evaluating prompt variations, APE can find more effective prompts than manual engineering, especially for complex tasks. It's a way of using AI to improve its own performance.

These techniques leverage LLMs' ability to understand and generate programming languages, enabling them to write new code, explain existing code, debug issues, and translate between languages. Effective code prompting typically involves clear specifications, appropriate context (libraries, frameworks, style guidelines), and sometimes examples of similar code. Temperature settings tend to be lower (0.1-0.3) for more deterministic outputs.

The effectiveness can be further enhanced by combining it with techniques like few-shot prompting or chain-of-thought. *Reference:* Chen, M., et al. (2021). "Evaluating Large Language Models Trained on Code." arXiv:2107.03374. link:https://arxiv.org/abs/2107.03374[https://arxiv.org/abs/2107.03374] == Conclusion Spring AI provides an elegant Java API for implementing all major prompt engineering techniques. By combining these techniques with Spring's powerful entity mapping and fluent API, developers can build sophisticated AI-powered applications with clean, maintainable code. The 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. For production applications, remember to: 1. Test prompts with different parameters (temperature, top-k, top-p) 2. Consider using self-consistency for critical decision-making 3. Leverage Spring AI's entity mapping for type-safe responses 4. Use contextual prompting to provide application-specific knowledge With these techniques and Spring AI's powerful abstractions, you can create robust AI-powered applications that deliver consistent, high-quality results. == References 1.

Please visit https://github.com/spring-ai-community/qianfan for the latest version. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chat-memory.adoc ================================================ [[ChatMemory]] = Chat Memory Large language models (LLMs) are stateless, meaning they do not retain information about previous interactions. 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. The `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. Before choosing a memory type, it's essential to understand the difference between chat memory and chat history. * *Chat Memory*. The information that a large-language model retains and uses to maintain contextual awareness throughout a conversation. * *Chat History*. The entire conversation history, including all messages exchanged between the user and the model. The `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. == Quick Start Spring 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. [source,java] ---- @Autowired ChatMemory chatMemory; ---- The following sections will describe further the different memory types and repositories available in Spring AI. == Memory Types The `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. === Message Window Chat Memory `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. [source,java] ---- MessageWindowChatMemory memory = MessageWindowChatMemory.builder() .maxMessages(10) .build(); ---- This is the default message type used by Spring AI to auto-configure a `ChatMemory` bean. == Memory Storage Spring 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. === In-Memory Repository `InMemoryChatMemoryRepository` stores messages in memory using a `ConcurrentHashMap`. By 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. [source,java] ---- @Autowired ChatMemoryRepository chatMemoryRepository; ---- If you'd rather create the `InMemoryChatMemoryRepository` manually, you can do so as follows: [source,java] ---- ChatMemoryRepository repository = new InMemoryChatMemoryRepository(); ---- === JdbcChatMemoryRepository `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. Messages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history. First, add the following dependency to your project: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-chat-memory-repository-jdbc ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-jdbc' } ---- ====== Spring AI provides auto-configuration for the `JdbcChatMemoryRepository`, that you can use directly in your application. [source,java] ---- @Autowired JdbcChatMemoryRepository chatMemoryRepository; ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- If you'd rather create the `JdbcChatMemoryRepository` manually, you can do so by providing a `JdbcTemplate` instance and a `JdbcChatMemoryRepositoryDialect`: [source,java] ---- ChatMemoryRepository chatMemoryRepository = JdbcChatMemoryRepository.builder() .jdbcTemplate(jdbcTemplate) .dialect(new PostgresChatMemoryRepositoryDialect()) .build(); ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- ==== Supported Databases and Dialect Abstraction Spring AI supports multiple relational databases via a dialect abstraction. The following databases are supported out-of-the-box: - PostgreSQL - MySQL / MariaDB - SQL Server - HSQLDB - Oracle Database The 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. ==== Configuration Properties [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value | `spring.ai.chat.memory.repository.jdbc.initialize-schema` | Controls when to initialize the schema. Values: `embedded` (default), `always`, `never`. | `embedded` | `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` | `spring.ai.chat.memory.repository.jdbc.platform` | Platform to use in initialization scripts if the @@platform@@ placeholder is used. | _auto-detected_ |=== ==== Schema Initialization The 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.). You can control schema initialization using the `spring.ai.chat.memory.repository.jdbc.initialize-schema` property: [source,properties] ---- spring.ai.chat.memory.repository.jdbc.initialize-schema=embedded # Only for embedded DBs (default) spring.ai.chat.memory.repository.jdbc.initialize-schema=always # Always initialize spring.ai.chat.memory.repository.jdbc.initialize-schema=never # Never initialize (useful with Flyway/Liquibase) ---- To override the schema script location, use: [source,properties] ---- spring.ai.chat.memory.repository.jdbc.schema=classpath:/custom/path/schema-mysql.sql ---- ==== Extending Dialects To 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. [source,java] ---- ChatMemoryRepository chatMemoryRepository = JdbcChatMemoryRepository.builder() .jdbcTemplate(jdbcTemplate) .dialect(new MyCustomDbDialect()) .build(); ---- === CassandraChatMemoryRepository `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. `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. Messages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history. To use `CassandraChatMemoryRepository` first, add the dependency to your project: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-chat-memory-repository-cassandra ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-cassandra' } ---- ====== Spring AI provides auto-configuration for the `CassandraChatMemoryRepository` that you can use directly in your application. [source,java] ---- @Autowired CassandraChatMemoryRepository chatMemoryRepository; ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- If you'd rather create the `CassandraChatMemoryRepository` manually, you can do so by providing a `CassandraChatMemoryRepositoryConfig` instance: [source,java] ---- ChatMemoryRepository chatMemoryRepository = CassandraChatMemoryRepository .create(CassandraChatMemoryRepositoryConfig.builder().withCqlSession(cqlSession)); ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- ==== Configuration Properties [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value | `spring.cassandra.contactPoints` | Host(s) to initiate cluster discovery | `127.0.0.1` | `spring.cassandra.port` | Cassandra native protocol port to connect to | `9042` | `spring.cassandra.localDatacenter` | Cassandra datacenter to connect to | `datacenter1` | `spring.ai.chat.memory.cassandra.time-to-live` | Time to live (TTL) for messages written in Cassandra | | `spring.ai.chat.memory.cassandra.keyspace` | Cassandra keyspace | `springframework` | `spring.ai.chat.memory.cassandra.messages-column` | Cassandra column name for messages | `springframework` | `spring.ai.chat.memory.cassandra.table` | Cassandra table | `ai_chat_memory` | `spring.ai.chat.memory.cassandra.initialize-schema` | Whether to initialize the schema on startup. | `true` |=== ==== Schema Initialization The auto-configuration will automatically create the `ai_chat_memory` table. You can disable the schema initialization by setting the property `spring.ai.chat.memory.repository.cassandra.initialize-schema` to `false`. === Neo4j ChatMemoryRepository `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. Messages are retrieved in ascending message index order (oldest-to-newest), which is the expected format for LLM conversation history. First, add the following dependency to your project: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-chat-memory-repository-neo4j ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-neo4j' } ---- ====== Spring AI provides auto-configuration for the `Neo4jChatMemoryRepository`, which you can use directly in your application. [source,java] ---- @Autowired Neo4jChatMemoryRepository chatMemoryRepository; ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- If you'd rather create the `Neo4jChatMemoryRepository` manually, you can do so by providing a Neo4j `Driver` instance: [source,java] ---- ChatMemoryRepository chatMemoryRepository = Neo4jChatMemoryRepository.builder() .driver(driver) .build(); ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- ==== Configuration Properties [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value | `spring.ai.chat.memory.repository.neo4j.sessionLabel` | The label for the nodes that store conversation sessions | `Session` | `spring.ai.chat.memory.repository.neo4j.messageLabel` | The label for the nodes that store messages | `Message` | `spring.ai.chat.memory.repository.neo4j.toolCallLabel` | The label for nodes that store tool calls (e.g. in Assistant Messages) | `ToolCall` | `spring.ai.chat.memory.repository.neo4j.metadataLabel` | The label for nodes that store message metadata | `Metadata` | `spring.ai.chat.memory.repository.neo4j.toolResponseLabel` | The label for the nodes that store tool responses | `ToolResponse` | `spring.ai.chat.memory.repository.neo4j.mediaLabel` | The label for the nodes that store media associated with a message | `Media` |=== ==== Index Initialization The 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. === CosmosDBChatMemoryRepository `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. Messages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history. First, add the following dependency to your project: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-chat-memory-repository-cosmos-db ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-cosmos-db' } ---- ====== Spring AI provides auto-configuration for the `CosmosDBChatMemoryRepository`, which you can use directly in your application. [source,java] ---- @Autowired CosmosDBChatMemoryRepository chatMemoryRepository; ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- If you'd rather create the `CosmosDBChatMemoryRepository` manually, you can do so by providing a `CosmosDBChatMemoryRepositoryConfig` instance: [source,java] ---- ChatMemoryRepository chatMemoryRepository = CosmosDBChatMemoryRepository .create(CosmosDBChatMemoryRepositoryConfig.builder() .withCosmosClient(cosmosAsyncClient) .withDatabaseName("chat-memory-db") .withContainerName("conversations") .build()); ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- ==== Configuration Properties [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value | `spring.ai.chat.memory.repository.cosmosdb.endpoint` | Azure Cosmos DB endpoint URI. Required for auto-configuration. | | `spring.ai.chat.memory.repository.cosmosdb.key` | Azure Cosmos DB primary or secondary key. If not provided, Azure Identity authentication will be used. | | `spring.ai.chat.memory.repository.cosmosdb.connection-mode` | Connection mode for Cosmos DB client (`direct` or `gateway`). | `gateway` | `spring.ai.chat.memory.repository.cosmosdb.database-name` | Name of the Cosmos DB database. | `SpringAIChatMemory` | `spring.ai.chat.memory.repository.cosmosdb.container-name` | Name of the Cosmos DB container. | `ChatMemory` | `spring.ai.chat.memory.repository.cosmosdb.partition-key-path` | Partition key path for the container. | `/conversationId` |=== ==== Authentication The Cosmos DB Chat Memory Repository supports two authentication methods: 1. **Key-based authentication**: Provide the `spring.ai.chat.memory.repository.cosmosdb.key` property with your Cosmos DB primary or secondary key. 2. **Azure Identity authentication**: When no key is provided, the repository uses Azure Identity (`DefaultAzureCredential`) to authenticate with managed identity, service principal, or other Azure credential sources. ==== Schema Initialization The auto-configuration will automatically create the specified database and container if they don't exist. 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. You can customize the database and container names using the configuration properties mentioned above. === MongoChatMemoryRepository `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. Messages 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. First, add the following dependency to your project: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-chat-memory-repository-mongodb ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-mongodb' } ---- ====== Spring AI provides auto-configuration for the `MongoChatMemoryRepository`, which you can use directly in your application. [source,java] ---- @Autowired MongoChatMemoryRepository chatMemoryRepository; ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- If you'd rather create the `MongoChatMemoryRepository` manually, you can do so by providing a `MongoTemplate` instance: [source,java] ---- ChatMemoryRepository chatMemoryRepository = MongoChatMemoryRepository.builder() .mongoTemplate(mongoTemplate) .build(); ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- ==== Configuration Properties [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value | `spring.ai.chat.memory.repository.mongo.create-indices` | Should indices be created or recreated automatically on startup. Note: Changing the * TTL value will drop the TTL index and recreate it | `false` | `spring.ai.chat.memory.repository.mongo.ttl` | Time to live (TTL) for messages written in MongoDB, in seconds. If not set, messages will be stored indefinitely. | `0` |=== ==== Collection Initialization The auto-configuration will automatically create the `ai_chat_memory` collection on startup if it does not already exist. === RedisChatMemoryRepository `RedisChatMemoryRepository` is a built-in implementation that uses Redis Stack (with Redis Query Engine and RedisJSON) to store chat messages. It is suitable for applications that require high-performance, low-latency chat memory persistence with optional TTL (time-to-live) support and advanced querying capabilities. The repository stores messages as JSON documents and creates a search index for efficient querying. It also provides extended query capabilities through the `AdvancedRedisChatMemoryRepository` interface for searching messages by content, type, time range, and metadata. Messages are retrieved in ascending timestamp order (oldest-to-newest), which is the expected format for LLM conversation history. First, add the following dependency to your project: [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-starter-model-chat-memory-repository-redis ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-chat-memory-repository-redis' } ---- ====== Spring AI provides auto-configuration for the `RedisChatMemoryRepository`, which you can use directly in your application. [source,java] ---- @Autowired RedisChatMemoryRepository chatMemoryRepository; ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- If you'd rather create the `RedisChatMemoryRepository` manually, you can do so by providing a `JedisPooled` client: [source,java] ---- JedisPooled jedisClient = new JedisPooled("localhost", 6379); ChatMemoryRepository chatMemoryRepository = RedisChatMemoryRepository.builder() .jedisClient(jedisClient) .indexName("my-chat-index") .keyPrefix("my-chat:") .timeToLive(Duration.ofHours(24)) .build(); ChatMemory chatMemory = MessageWindowChatMemory.builder() .chatMemoryRepository(chatMemoryRepository) .maxMessages(10) .build(); ---- ==== Configuration Properties [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value | `spring.ai.chat.memory.redis.host` | Redis server host | `localhost` | `spring.ai.chat.memory.redis.port` | Redis server port | `6379` | `spring.ai.chat.memory.redis.index-name` | Name of the Redis search index | `chat-memory-idx` | `spring.ai.chat.memory.redis.key-prefix` | Key prefix for chat memory entries | `chat-memory:` | `spring.ai.chat.memory.redis.time-to-live` | Time to live for chat memory entries (e.g., `24h`, `30d`) | _no expiration_ | `spring.ai.chat.memory.redis.initialize-schema` | Whether to initialize the Redis schema on startup | `true` | `spring.ai.chat.memory.redis.max-conversation-ids` | Maximum number of conversation IDs to return | `1000` | `spring.ai.chat.memory.redis.max-messages-per-conversation` | Maximum number of messages to return per conversation | `1000` |=== ==== Advanced Querying The `RedisChatMemoryRepository` also implements `AdvancedRedisChatMemoryRepository`, which provides extended query capabilities: [source,java] ---- // Cast to access advanced features AdvancedRedisChatMemoryRepository advancedRepo = (AdvancedRedisChatMemoryRepository) chatMemoryRepository; // Find messages by type across all conversations List userMessages = advancedRepo.findByType(MessageType.USER, 100); // Find messages containing specific content List results = advancedRepo.findByContent("Spring AI", 50); // Find messages within a time range List recentMessages = advancedRepo.findByTimeRange( conversationId, Instant.now().minus(Duration.ofHours(1)), Instant.now(), 100 ); // Find messages by metadata List priorityMessages = advancedRepo.findByMetadata("priority", "high", 50); // Execute custom Redis queries List customResults = advancedRepo.executeQuery("@type:USER @content:Redis", 100); ---- ==== Metadata Field Indexing To enable efficient querying on custom metadata fields, you can configure metadata field definitions: [source,properties] ---- spring.ai.chat.memory.redis.metadata-fields[0].name=priority spring.ai.chat.memory.redis.metadata-fields[0].type=tag spring.ai.chat.memory.redis.metadata-fields[1].name=score spring.ai.chat.memory.redis.metadata-fields[1].type=numeric spring.ai.chat.memory.redis.metadata-fields[2].name=category spring.ai.chat.memory.redis.metadata-fields[2].type=tag ---- Supported field types are: `tag` (for exact match filtering), `text` (for full-text search), and `numeric` (for range queries). ==== Schema Initialization The auto-configuration will automatically create the Redis search index on startup if it does not already exist. You can disable this behavior by setting `spring.ai.chat.memory.redis.initialize-schema=false`. ==== Requirements * Redis Stack 7.0 or higher (includes Redis Query Engine and RedisJSON modules) * Jedis client library (included as a dependency) == Memory in Chat Client When using the ChatClient API, you can provide a `ChatMemory` implementation to maintain conversation context across multiple interactions. Spring AI provides a few built-in Advisors that you can use to configure the memory behavior of the `ChatClient`, based on your needs. WARNING: 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]. * `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. * `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. * `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. For example, if you want to use `MessageWindowChatMemory` with the `MessageChatMemoryAdvisor`, you can configure it as follows: [source,java] ---- ChatMemory chatMemory = MessageWindowChatMemory.builder().build(); ChatClient chatClient = ChatClient.builder(chatModel) .defaultAdvisors(MessageChatMemoryAdvisor.builder(chatMemory).build()) .build(); ---- When 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: [source,java] ---- String conversationId = "007"; chatClient.prompt() .user("Do I have license to code?") .advisors(a -> a.param(ChatMemory.CONVERSATION_ID, conversationId)) .call() .content(); ---- === PromptChatMemoryAdvisor ==== Custom Template The `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. NOTE: 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. The 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: * an `instructions` placeholder to receive the original system message. * a `memory` placeholder to receive the retrieved conversation memory. === VectorStoreChatMemoryAdvisor ==== Custom Template The `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. NOTE: 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. The 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: * an `instructions` placeholder to receive the original system message. * a `long_term_memory` placeholder to receive the retrieved conversation memory. == Memory in Chat Model If you're working directly with a `ChatModel` instead of a `ChatClient`, you can manage the memory explicitly: [source,java] ---- // Create a memory instance ChatMemory chatMemory = MessageWindowChatMemory.builder().build(); String conversationId = "007"; // First interaction UserMessage userMessage1 = new UserMessage("My name is James Bond"); chatMemory.add(conversationId, userMessage1); ChatResponse response1 = chatModel.call(new Prompt(chatMemory.get(conversationId))); chatMemory.add(conversationId, response1.getResult().getOutput()); // Second interaction UserMessage userMessage2 = new UserMessage("What is my name?"); chatMemory.add(conversationId, userMessage2); ChatResponse response2 = chatModel.call(new Prompt(chatMemory.get(conversationId))); chatMemory.add(conversationId, response2.getResult().getOutput()); // The response will contain "James Bond" ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chatclient.adoc ================================================ [[ChatClient]] = Chat Client API The `ChatClient` offers a fluent API for communicating with an AI Model. It supports both a synchronous and streaming programming model. [NOTE] ==== See 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` ==== The 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. The `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. The 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. These 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. There 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. == Creating a ChatClient The `ChatClient` is created using a `ChatClient.Builder` object. You can obtain an autoconfigured `ChatClient.Builder` instance for any xref:api/chatmodel.adoc[ChatModel] Spring Boot autoconfiguration or create one programmatically. === Using an autoconfigured ChatClient.Builder In the most simple use case, Spring AI provides Spring Boot autoconfiguration, creating a prototype `ChatClient.Builder` bean for you to inject into your class. Here is a simple example of retrieving a `String` response to a simple user request. [source,java] ---- @RestController class MyController { private final ChatClient chatClient; public MyController(ChatClient.Builder chatClientBuilder) { this.chatClient = chatClientBuilder.build(); } @GetMapping("/ai") String generation(String userInput) { return this.chatClient.prompt() .user(userInput) .call() .content(); } } ---- In this simple example, the user input sets the contents of the user message. The `call()` method sends a request to the AI model, and the `content()` method returns the AI model's response as a `String`. === Working with Multiple Chat Models There are several scenarios where you might need to work with multiple chat models in a single application: * Using different models for different types of tasks (e.g., a powerful model for complex reasoning and a faster, cheaper model for simpler tasks) * Implementing fallback mechanisms when one model service is unavailable * A/B testing different models or configurations * Providing users with a choice of models based on their preferences * Combining specialized models (one for code generation, another for creative content, etc.) By default, Spring AI autoconfigures a single `ChatClient.Builder` bean. However, you may need to work with multiple chat models in your application. Here's how to handle this scenario: In all cases, you need to disable the `ChatClient.Builder` autoconfiguration by setting the property `spring.ai.chat.client.enabled=false`. This allows you to create multiple `ChatClient` instances manually. ==== Multiple ChatClients with a Single Model Type This 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. [source,java] ---- // Create ChatClient instances programmatically ChatModel myChatModel = ... // already autoconfigured by Spring Boot ChatClient chatClient = ChatClient.create(myChatModel); // Or use the builder for more control ChatClient.Builder builder = ChatClient.builder(myChatModel); ChatClient customChatClient = builder .defaultSystemPrompt("You are a helpful assistant.") .build(); ---- ==== ChatClients for Different Model Types When working with multiple AI models, you can define separate `ChatClient` beans for each model: [source,java] ---- import org.springframework.ai.chat.ChatClient; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class ChatClientConfig { @Bean public ChatClient openAiChatClient(OpenAiChatModel chatModel) { return ChatClient.create(chatModel); } @Bean public ChatClient anthropicChatClient(AnthropicChatModel chatModel) { return ChatClient.create(chatModel); } } ---- You can then inject these beans into your application components using the `@Qualifier` annotation: [source,java] ---- @Configuration public class ChatClientExample { @Bean CommandLineRunner cli( @Qualifier("openAiChatClient") ChatClient openAiChatClient, @Qualifier("anthropicChatClient") ChatClient anthropicChatClient) { return args -> { var scanner = new Scanner(System.in); ChatClient chat; // Model selection System.out.println("\nSelect your AI model:"); System.out.println("1. OpenAI"); System.out.println("2. Anthropic"); System.out.print("Enter your choice (1 or 2): "); String choice = scanner.nextLine().trim(); if (choice.equals("1")) { chat = openAiChatClient; System.out.println("Using OpenAI model"); } else { chat = anthropicChatClient; System.out.println("Using Anthropic model"); } // Use the selected chat client System.out.print("\nEnter your question: "); String input = scanner.nextLine(); String response = chat.prompt(input).call().content(); System.out.println("ASSISTANT: " + response); scanner.close(); }; } } ---- ==== Multiple OpenAI-Compatible API Endpoints The `OpenAiApi` and `OpenAiChatModel` classes provide a `mutate()` method that allows you to create variations of existing instances with different properties. This is particularly useful when you need to work with multiple OpenAI-compatible APIs. [source,java] ---- @Service public class MultiModelService { private static final Logger logger = LoggerFactory.getLogger(MultiModelService.class); @Autowired private OpenAiChatModel baseChatModel; @Autowired private OpenAiApi baseOpenAiApi; public void multiClientFlow() { try { // Derive a new OpenAiApi for Groq (Llama3) OpenAiApi groqApi = baseOpenAiApi.mutate() .baseUrl("https://api.groq.com/openai") .apiKey(System.getenv("GROQ_API_KEY")) .build(); // Derive a new OpenAiApi for OpenAI GPT-4 OpenAiApi gpt4Api = baseOpenAiApi.mutate() .baseUrl("https://api.openai.com") .apiKey(System.getenv("OPENAI_API_KEY")) .build(); // Derive a new OpenAiChatModel for Groq OpenAiChatModel groqModel = baseChatModel.mutate() .openAiApi(groqApi) .defaultOptions(OpenAiChatOptions.builder().model("llama3-70b-8192").temperature(0.5).build()) .build(); // Derive a new OpenAiChatModel for GPT-4 OpenAiChatModel gpt4Model = baseChatModel.mutate() .openAiApi(gpt4Api) .defaultOptions(OpenAiChatOptions.builder().model("gpt-4").temperature(0.7).build()) .build(); // Simple prompt for both models String prompt = "What is the capital of France?"; String groqResponse = ChatClient.builder(groqModel).build().prompt(prompt).call().content(); String gpt4Response = ChatClient.builder(gpt4Model).build().prompt(prompt).call().content(); logger.info("Groq (Llama3) response: {}", groqResponse); logger.info("OpenAI GPT-4 response: {}", gpt4Response); } catch (Exception e) { logger.error("Error in multi-client flow", e); } } } ---- == ChatClient Fluent API The `ChatClient` fluent API allows you to create a prompt in three distinct ways using an overloaded `prompt` method to initiate the fluent API: * `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. * `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. * `prompt(String content)`: This is a convenience method similar to the previous overload. It takes the user's text content. == ChatClient Responses The `ChatClient` API offers several ways to format the response from the AI Model using the fluent API. === Returning a ChatResponse The response from the AI model is a rich structure defined by the type `xref:api/chatmodel.adoc#ChatResponse[ChatResponse]`. It 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. The metadata includes the number of tokens (each token is approximately 3/4 of a word) used to create the response. This information is important because hosted AI models charge based on the number of tokens used per request. An example to return the `ChatResponse` object that contains the metadata is shown below by invoking `chatResponse()` after the `call()` method. [source,java] ---- ChatResponse chatResponse = chatClient.prompt() .user("Tell me a joke") .call() .chatResponse(); ---- === Returning an Entity You often want to return an entity class that is mapped from the returned `String`. The `entity()` method provides this functionality. For example, given the Java record: [source,java] ---- record ActorFilms(String actor, List movies) {} ---- You can easily map the AI model's output to this record using the `entity()` method, as shown below: [source,java] ---- ActorFilms actorFilms = chatClient.prompt() .user("Generate the filmography for a random actor.") .call() .entity(ActorFilms.class); ---- There is also an overloaded `entity` method with the signature `entity(ParameterizedTypeReference type)` that lets you specify types such as generic Lists: [source,java] ---- List actorFilms = chatClient.prompt() .user("Generate the filmography of 5 movies for Tom Hanks and Bill Murray.") .call() .entity(new ParameterizedTypeReference>() {}); ---- ==== Native Structured Output As 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`. You 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: [source,java] ---- ActorFilms actorFilms = chatClient.prompt() .advisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT) .user("Generate the filmography for a random actor.") .call() .entity(ActorFilms.class); ---- NOTE: Some AI models such as OpenAI don't support arrays of objects natively. In such cases, you can use the Spring AI default structured output conversion. === Streaming Responses The `stream()` method lets you get an asynchronous response as shown below: [source,java] ---- Flux output = chatClient.prompt() .user("Tell me a joke") .stream() .content(); ---- You can also stream the `ChatResponse` using the method `Flux chatResponse()`. In the future, we will offer a convenience method that will let you return a Java entity with the reactive `stream()` method. In 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. This also demonstrates the use of parameters in the fluent API that will be discussed in more detail in a later section of the documentation. [source,java] ---- var converter = new BeanOutputConverter<>(new ParameterizedTypeReference>() {}); Flux flux = this.chatClient.prompt() .user(u -> u.text(""" Generate the filmography for a random actor. {format} """) .param("format", this.converter.getFormat())) .stream() .content(); String content = this.flux.collectList().block().stream().collect(Collectors.joining()); List actorFilms = this.converter.convert(this.content); ---- == Prompt Templates The `ChatClient` fluent API lets you provide user and system text as templates with variables that are replaced at runtime. [source,java] ---- String answer = ChatClient.create(chatModel).prompt() .user(u -> u .text("Tell me the names of 5 movies whose soundtrack was composed by {composer}") .param("composer", "John Williams")) .call() .content(); ---- Internally, 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. 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. Spring AI also provides a `NoOpTemplateRenderer` for cases where no template processing is desired. NOTE: 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()`). It 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]). If 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. For example, by 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. [source,java] ---- String answer = ChatClient.create(chatModel).prompt() .user(u -> u .text("Tell me the names of 5 movies whose soundtrack was composed by ") .param("composer", "John Williams")) .templateRenderer(StTemplateRenderer.builder().startDelimiterToken('<').endDelimiterToken('>').build()) .call() .content(); ---- == call() return values After specifying the `call()` method on `ChatClient`, there are a few different options for the response type. * `String content()`: returns the String content of the response * `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. * `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). * `entity()` to return a Java type ** `entity(ParameterizedTypeReference type)`: used to return a `Collection` of entity types. ** `entity(Class type)`: used to return a specific entity type. ** `entity(StructuredOutputConverter structuredOutputConverter)`: used to specify an instance of a `StructuredOutputConverter` to convert a `String` to an entity type. * `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. ** `responseEntity(Class type)`: used to return a `ResponseEntity` containing both the complete `ChatResponse` object and a specific entity type. ** `responseEntity(ParameterizedTypeReference type)`: used to return a `ResponseEntity` containing both the complete `ChatResponse` object and a `Collection` of entity types. ** `responseEntity(StructuredOutputConverter structuredOutputConverter)`: used to return a `ResponseEntity` containing both the complete `ChatResponse` object and an entity converted using a specified `StructuredOutputConverter`. You can also invoke the `stream()` method instead of `call()`. NOTE: 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. The actual AI model invocation occurs when methods such as `content()`, `chatResponse()`, and `responseEntity()` are called. == stream() return values After specifying the `stream()` method on `ChatClient`, there are a few options for the response type: * `Flux content()`: Returns a `Flux` of the string being generated by the AI model. * `Flux chatResponse()`: Returns a `Flux` of the `ChatResponse` object, which contains additional metadata about the response. * `Flux 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). == Message Metadata The ChatClient supports adding metadata to both user and system messages. Metadata provides additional context and information about messages that can be used by the AI model or downstream processing. === Adding Metadata to User Messages You can add metadata to user messages using the `metadata()` methods: [source,java] ---- // Adding individual metadata key-value pairs String response = chatClient.prompt() .user(u -> u.text("What's the weather like?") .metadata("messageId", "msg-123") .metadata("userId", "user-456") .metadata("priority", "high")) .call() .content(); // Adding multiple metadata entries at once Map userMetadata = Map.of( "messageId", "msg-123", "userId", "user-456", "timestamp", System.currentTimeMillis() ); String response = chatClient.prompt() .user(u -> u.text("What's the weather like?") .metadata(userMetadata)) .call() .content(); ---- === Adding Metadata to System Messages Similarly, you can add metadata to system messages: [source,java] ---- // Adding metadata to system messages String response = chatClient.prompt() .system(s -> s.text("You are a helpful assistant.") .metadata("version", "1.0") .metadata("model", "gpt-4")) .user("Tell me a joke") .call() .content(); ---- === Default Metadata Support You can also configure default metadata at the ChatClient builder level: [source,java] ---- @Configuration class Config { @Bean ChatClient chatClient(ChatClient.Builder builder) { return builder .defaultSystem(s -> s.text("You are a helpful assistant") .metadata("assistantType", "general") .metadata("version", "1.0")) .defaultUser(u -> u.text("Default user context") .metadata("sessionId", "default-session")) .build(); } } ---- === Metadata Validation The ChatClient validates metadata to ensure data integrity: * Metadata keys cannot be null or empty * Metadata values cannot be null * When passing a Map, neither keys nor values can contain null elements [source,java] ---- // This will throw an IllegalArgumentException chatClient.prompt() .user(u -> u.text("Hello") .metadata(null, "value")) // Invalid: null key .call() .content(); // This will also throw an IllegalArgumentException chatClient.prompt() .user(u -> u.text("Hello") .metadata("key", null)) // Invalid: null value .call() .content(); ---- === Accessing Metadata The metadata is included in the generated UserMessage and SystemMessage objects and can be accessed through the message's `getMetadata()` method. This is particularly useful when processing messages in advisors or when examining the conversation history. == Using Defaults Creating a `ChatClient` with a default system text in an `@Configuration` class simplifies runtime code. By 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. === Default System Text In the following example, we will configure the system text to always reply in a pirate's voice. To avoid repeating the system text in runtime code, we will create a `ChatClient` instance in a `@Configuration` class. [source,java] ---- @Configuration class Config { @Bean ChatClient chatClient(ChatClient.Builder builder) { return builder.defaultSystem("You are a friendly chat bot that answers question in the voice of a Pirate") .build(); } } ---- and a `@RestController` to invoke it: [source,java] ---- @RestController class AIController { private final ChatClient chatClient; AIController(ChatClient chatClient) { this.chatClient = chatClient; } @GetMapping("/ai/simple") public Map completion(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { return Map.of("completion", this.chatClient.prompt().user(message).call().content()); } } ---- When calling the application endpoint via curl, the result is: [source,bash] ---- ❯ curl localhost:8080/ai/simple {"completion":"Why did the pirate go to the comedy club? To hear some arrr-rated jokes! Arrr, matey!"} ---- === Default System Text with parameters In 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. [source,java] ---- @Configuration class Config { @Bean ChatClient chatClient(ChatClient.Builder builder) { return builder.defaultSystem("You are a friendly chat bot that answers question in the voice of a {voice}") .build(); } } ---- [source,java] ---- @RestController class AIController { private final ChatClient chatClient; AIController(ChatClient chatClient) { this.chatClient = chatClient; } @GetMapping("/ai") Map completion(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message, String voice) { return Map.of("completion", this.chatClient.prompt() .system(sp -> sp.param("voice", voice)) .user(message) .call() .content()); } } ---- When calling the application endpoint via httpie, the result is: [source.bash] ---- http localhost:8080/ai voice=='Robert DeNiro' { "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?" } ---- === Other defaults At the `ChatClient.Builder` level, you can specify the default prompt configuration. * `defaultOptions(ChatOptions chatOptions)`: Pass in either portable options defined in the `ChatOptions` class or model-specific options such as those in `OpenAiChatOptions`. For more information on model-specific `ChatOptions` implementations, refer to the JavaDocs. * `defaultFunction(String name, String description, java.util.function.Function function)`: The `name` is used to refer to the function in user text. The `description` explains the function's purpose and helps the AI model choose the correct function for an accurate response. The `function` argument is a Java function instance that the model will execute when necessary. * `defaultFunctions(String... functionNames)`: The bean names of `java.util.Function`s defined in the application context. * `defaultUser(String text)`, `defaultUser(Resource text)`, `defaultUser(Consumer userSpecConsumer)`: These methods let you define the user text. The `Consumer` allows you to use a lambda to specify the user text and any default parameters. * `defaultAdvisors(Advisor... advisor)`: Advisors allow modification of the data used to create the `Prompt`. The `QuestionAnswerAdvisor` implementation enables the pattern of `Retrieval Augmented Generation` by appending the prompt with context information related to the user text. * `defaultAdvisors(Consumer 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`. The `Consumer` 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. You can override these defaults at runtime using the corresponding methods without the `default` prefix. * `options(ChatOptions.Builder optionsCustomizer)` * `function(String name, String description, java.util.function.Function function)` * `functions(String... functionNames)` * `user(String text)`, `user(Resource text)`, `user(Consumer userSpecConsumer)` * `advisors(Advisor... advisor)` * `advisors(Consumer advisorSpecConsumer)` image::chat-client-options-merging.png[align="center"] == Advisors The xref:api/advisors.adoc[Advisors API] provides a flexible and powerful way to intercept, modify, and enhance AI-driven interactions in your Spring applications. A common pattern when calling an AI model with user text is to append or augment the prompt with contextual data. This contextual data can be of different types. Common types include: * **Your own data**: This is data the AI model hasn't been trained on. Even if the model has seen similar data, the appended contextual data takes precedence in generating the response. * **Conversational history**: The chat model's API is stateless. If you tell the AI model your name, it won't remember it in subsequent interactions. Conversational history must be sent with each request to ensure previous interactions are considered when generating a response. === Advisor Configuration in ChatClient The ChatClient fluent API provides an `AdvisorSpec` interface for configuring advisors. This interface offers methods to add parameters, set multiple parameters at once, and add one or more advisors to the chain. [source,java] ---- interface AdvisorSpec { AdvisorSpec param(String k, Object v); AdvisorSpec params(Map p); AdvisorSpec advisors(Advisor... advisors); AdvisorSpec advisors(List advisors); } ---- IMPORTANT: The order in which advisors are added to the chain is crucial, as it determines the sequence of their execution. Each 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. [source,java] ---- ChatClient.builder(chatModel) .build() .prompt() .advisors( MessageChatMemoryAdvisor.builder(chatMemory).build(), QuestionAnswerAdvisor.builder(vectorStore).build() ) .user(userText) .call() .content(); ---- In this configuration, the `MessageChatMemoryAdvisor` will be executed first, adding the conversation history to the prompt. Then, the `QuestionAnswerAdvisor` will perform its search based on the user's question and the added conversation history, potentially providing more relevant results. xref:ROOT:api/retrieval-augmented-generation.adoc#_questionansweradvisor[Learn about Question Answer Advisor] === Retrieval Augmented Generation Refer to the xref:ROOT:api/retrieval-augmented-generation.adoc[Retrieval Augmented Generation] guide. === Logging The `SimpleLoggerAdvisor` is an advisor that logs the `request` and `response` data of the `ChatClient`. This can be useful for debugging and monitoring your AI interactions. TIP: Spring AI supports observability for LLM and vector store interactions. Refer to the xref:observability/index.adoc[Observability] guide for more information. To enable logging, add the `SimpleLoggerAdvisor` to the advisor chain when creating your ChatClient. It's recommended to add it toward the end of the chain: [source,java] ---- ChatResponse response = ChatClient.create(chatModel).prompt() .advisors(new SimpleLoggerAdvisor()) .user("Tell me a joke?") .call() .chatResponse(); ---- To see the logs, set the logging level for the advisor package to `DEBUG`: ---- logging.level.org.springframework.ai.chat.client.advisor=DEBUG ---- Add this to your `application.properties` or `application.yaml` file. You can customize what data from `AdvisedRequest` and `ChatResponse` is logged by using the following constructor: [source,java] ---- SimpleLoggerAdvisor( Function requestToString, Function responseToString, int order ) ---- Example usage: [source,java] ---- SimpleLoggerAdvisor customLogger = new SimpleLoggerAdvisor( request -> "Custom request: " + request.prompt().getUserMessage(), response -> "Custom response: " + response.getResult(), 0 ); ---- This allows you to tailor the logged information to your specific needs. TIP: Be cautious about logging sensitive information in production environments. == Chat Memory The interface `ChatMemory` represents a storage for chat conversation memory. It provides methods to add messages to a conversation, retrieve messages from a conversation, and clear the conversation history. There is currently one built-in implementation: `MessageWindowChatMemory`. `MessageWindowChatMemory` is a chat memory implementation that maintains a window of messages up to a specified maximum size (default: 20 messages). When the number of messages exceeds this limit, older messages are evicted, but system messages are preserved. If a new system message is added, all previous system messages are removed from memory. This ensures that the most recent context is always available for the conversation while keeping memory usage bounded. The `MessageWindowChatMemory` is backed by the `ChatMemoryRepository` abstraction which provides storage implementations for the chat conversation memory. There are several implementations available, including the `InMemoryChatMemoryRepository`, `JdbcChatMemoryRepository`, `CassandraChatMemoryRepository`, `Neo4jChatMemoryRepository`, `CosmosDBChatMemoryRepository`, `MongoChatMemoryRepository`, and `RedisChatMemoryRepository`. For more details and usage examples, see the xref:api/chat-memory.adoc[Chat Memory] documentation. == Implementation Notes The combined use of imperative and reactive programming models in `ChatClient` is a unique aspect of the API. Often an application will be either reactive or imperative, but not both. * When customizing the HTTP client interactions of a Model implementation, both the RestClient and the WebClient must be configured. [IMPORTANT] ==== Due to a bug in Spring Boot 3.4, the "spring.http.client.factory=jdk" property must be set. Otherwise, it's set to "reactor" by default, which breaks certain AI workflows like the ImageModel. ==== * Streaming is only supported via the Reactive stack. Imperative applications must include the Reactive stack for this reason (e.g. spring-boot-starter-webflux). * Non-streaming is only supportive via the Servlet stack. Reactive applications must include the Servlet stack for this reason (e.g. spring-boot-starter-web) and expect some calls to be blocking. * Tool calling is imperative, leading to blocking workflows. This 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). * The built-in advisors perform blocking operations for standards calls, and non-blocking operations for streaming calls. The Reactor Scheduler used for the advisor streaming calls can be configured via the Builder on each Advisor class. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/chatmodel.adoc ================================================ [[ChatModel]] = Chat Model API The 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. The 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. The `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. This design aligns with Spring's philosophy of modularity and interchangeability. Also 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. It manages the complexity of request preparation and response parsing, offering a direct and simplified API interaction. You 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. == API Overview This section provides a guide to the Spring AI Chat Model API interface and associated classes. === ChatModel Here 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: [source,java] ---- public interface ChatModel extends Model, StreamingChatModel { default String call(String message) {...} @Override ChatResponse call(Prompt prompt); } ---- The `call()` method with a `String` parameter simplifies initial use, avoiding the complexities of the more sophisticated `Prompt` and `ChatResponse` classes. In real-world applications, it is more common to use the `call()` method that takes a `Prompt` instance and returns a `ChatResponse`. === StreamingChatModel Here 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: [source,java] ---- public interface StreamingChatModel extends StreamingModel { default Flux stream(String message) {...} @Override Flux stream(Prompt prompt); } ---- The `stream()` method takes a `String` or `Prompt` parameter similar to `ChatModel` but it streams the responses using the reactive Flux API. === Prompt The 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. The following listing shows a truncated version of the `Prompt` class, excluding constructors and other utility methods: [source,java] ---- public class Prompt implements ModelRequest> { private final List messages; private ChatOptions modelOptions; @Override public ChatOptions getOptions() {...} @Override public List getInstructions() {...} // constructors and utility methods omitted } ---- ==== Message The `Message` interface encapsulates a `Prompt` textual content, a collection of metadata attributes, and a categorization known as `MessageType`. The interface is defined as follows: [source,java] ---- public interface Content { String getText(); Map getMetadata(); } public interface Message extends Content { MessageType getMessageType(); } ---- The multimodal message types implement also the `MediaContent` interface providing a list of `Media` content objects. [source,java] ---- public interface MediaContent extends Content { Collection getMedia(); } ---- The `Message` interface has various implementations that correspond to the categories of messages that an AI model can process: image::spring-ai-message-api.jpg[Spring AI Message API, width=800, align="center"] The chat completion endpoint, distinguish between message categories based on conversational roles, effectively mapped by the `MessageType`. For instance, OpenAI recognizes message categories for distinct conversational roles such as `system`, `user`, `function`, or `assistant`. While the term `MessageType` might imply a specific message format, in this context it effectively designates the role a message plays in the dialogue. For AI models that do not use specific roles, the `UserMessage` implementation acts as a standard category, typically representing user-generated inquiries or instructions. To 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. ==== Chat Options Represents 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. The `ChatOptions` class is defined as follows: [source,java] ---- public interface ChatOptions extends ModelOptions { String getModel(); Float getFrequencyPenalty(); Integer getMaxTokens(); Float getPresencePenalty(); List getStopSequences(); Float getTemperature(); Integer getTopK(); Float getTopP(); ChatOptions copy(); } ---- Additionally, 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`. Spring AI provides a sophisticated system for configuring and using Chat Models. It allows for default configuration to be set at start-up, while also providing the flexibility to override these settings on a per-request basis. This 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. When 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). The xref:api/chatclient.adoc[ChatClient] abstraction allows for an incremental approach where users can provide a "delta" customizer that Following flow diagram illustrates how Spring AI handles the configuration and execution of Chat Models: image::chat-model-conversions.png[align="center", width="800px"] 1. Start-up Configuration - The ChatModel/StreamingChatModel is initialized with "Start-Up" Chat Options. These options are set during the ChatModel initialization and are meant to provide default configurations. 2. Runtime Configuration - For each request, the Prompt can contain a Runtime Chat Options: These fully override the start-up options. 3. Input Processing - The "Convert Input" step transforms the input instructions into native, model-specific formats. 4. Output Processing - The "Convert Output" step transforms the model's response into a standardized `ChatResponse` format. [[ChatResponse]] === ChatResponse The structure of the `ChatResponse` class is as follows: [source,java] ---- public class ChatResponse implements ModelResponse { private final ChatResponseMetadata chatResponseMetadata; private final List generations; @Override public ChatResponseMetadata getMetadata() {...} @Override public List getResults() {...} // other methods omitted } ---- The 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. The `ChatResponse` class also carries a `ChatResponseMetadata` metadata about the AI Model's response. [[Generation]] === Generation Finally, 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: [source,java] ---- public class Generation implements ModelResult { private final AssistantMessage assistantMessage; private ChatGenerationMetadata chatGenerationMetadata; @Override public AssistantMessage getOutput() {...} @Override public ChatGenerationMetadata getMetadata() {...} // other methods omitted } ---- == Available Implementations This 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. image::spring-ai-chat-completions-clients.jpg[align="center", width="1000px"] * xref:api/chat/openai-chat.adoc[OpenAI Chat Completion] (streaming, multi-modality & function-calling support) * xref:api/chat/azure-openai-chat.adoc[Microsoft Azure Open AI Chat Completion] (streaming & function-calling support) * xref:api/chat/ollama-chat.adoc[Ollama Chat Completion] (streaming, multi-modality & function-calling support) * xref:api/bedrock.adoc[Amazon Bedrock] * xref:api/chat/mistralai-chat.adoc[Mistral AI Chat Completion] (streaming & function-calling support) * xref:api/chat/anthropic-chat.adoc[Anthropic Chat Completion] (streaming & function-calling support) TIP: Find a detailed comparison of the available Chat Models in the xref:api/chat/comparison.adoc[Chat Models Comparison] section. == Chat Model API The Spring AI Chat Model API is built on top of the Spring AI `Generic Model API` providing Chat specific abstractions and implementations.

This allows applications to specify a binding type for a provider and then express properties using a generic format. The spring-ai cloud bindings will process these properties and bind them to spring-ai native properties. For example, when using `OpenAi`, the binding type is `openai`. Using the property `spring.ai.cloud.bindings.openai.enabled`, the binding processor can be enabled or disabled. By default, when specifying a binding type, this property will be enabled. Configuration for `api-key`, `uri`, `username`, `password`, etc. can be specified and spring-ai will map them to the corresponding properties in the supported system. To enable cloud binding support, include the following dependency in the application. [source,xml] ---- org.springframework.ai spring-ai-spring-cloud-bindings ---- or to your Gradle `build.gradle` build file.

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]. image::https://raw.githubusercontent.com/spring-io/spring-io-static/refs/heads/main/blog/tzolov/spring-ai-agentic-systems.jpg[Agent Systems, width=350] While 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. The 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. == Agentic Systems The research publication makes an important architectural distinction between two types of agentic systems: . *Workflows*: Systems where LLMs and tools are orchestrated through predefined code paths (e.g., prescriptive systems) . *Agents*: Systems where LLMs dynamically direct their own processes and tool usage The 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. Let's examine how Spring AI implements these concepts through five fundamental patterns, each serving specific use cases: === 1. https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns/chain-workflow[Chain Workflow] The Chain Workflow pattern exemplifies the principle of breaking down complex tasks into simpler, more manageable steps. image::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] *When to Use:* - Tasks with clear sequential steps - When you want to trade latency for higher accuracy - When each step builds on the previous step's output Here's a practical example from Spring AI's implementation: [source,java] ---- public class ChainWorkflow { private final ChatClient chatClient; private final String[] systemPrompts; public String chain(String userInput) { String response = userInput; for (String prompt : systemPrompts) { String input = String.format("{%s}\n {%s}", prompt, response); response = chatClient.prompt(input).call().content(); } return response; } } ---- This implementation demonstrates several key principles: - Each step has a focused responsibility - Output from one step becomes input for the next - The chain is easily extensible and maintainable === 2. https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns/parallelization-workflow[Parallelization Workflow] LLMs can work simultaneously on tasks and have their outputs aggregated programmatically. image::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] *When to Use:* - Processing large volumes of similar but independent items - Tasks requiring multiple independent perspectives - When processing time is critical and tasks are parallelizable [source,java] ---- List parallelResponse = new ParallelizationWorkflow(chatClient) .parallel( "Analyze how market changes will impact this stakeholder group.", List.of( "Customers: ...", "Employees: ...", "Investors: ...", "Suppliers: ..." ), 4 ); ---- === 3. https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns/routing-workflow[Routing Workflow] The Routing pattern implements intelligent task distribution, enabling specialized handling for different types of input. image::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] *When to Use:* - Complex tasks with distinct categories of input - When different inputs require specialized processing - When classification can be handled accurately [source,java] ---- @Autowired private ChatClient chatClient; RoutingWorkflow workflow = new RoutingWorkflow(chatClient); Map routes = Map.of( "billing", "You are a billing specialist. Help resolve billing issues...", "technical", "You are a technical support engineer. Help solve technical problems...", "general", "You are a customer service representative. Help with general inquiries..." ); String input = "My account was charged twice last week"; String response = workflow.route(input, routes); ---- === 4. https://github.com/spring-projects/spring-ai-examples/tree/main/agentic-patterns/orchestrator-workers[Orchestrator-Workers] image::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] *When to Use:* - Complex tasks where subtasks can't be predicted upfront - Tasks requiring different approaches or perspectives - Situations needing adaptive problem-solving [source,java] ---- public class OrchestratorWorkersWorkflow { public WorkerResponse process(String taskDescription) { // 1.

By following these patterns and principles, developers can create robust, maintainable, and effective AI applications that deliver real value while avoiding unnecessary complexity. The key is to remember that sometimes the simplest solution is the most effective. Start with basic patterns, understand your use case thoroughly, and only add complexity when it demonstrably improves your system's performance or capabilities. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/embeddings/azure-openai-embeddings.adoc ================================================ = Azure OpenAI Embeddings Azure's OpenAI extends the OpenAI capabilities, offering safe text generation and Embeddings computation models for various task: - Similarity embeddings are good at capturing semantic similarity between two or more pieces of text. - Text search embeddings help measure whether long documents are relevant to a short query. - Code search embeddings are useful for embedding code snippets and embedding natural language search queries. The Azure OpenAI embeddings rely on `cosine similarity` to compute similarity between documents and a query. == Prerequisites The Azure OpenAI client offers three options to connect: using an Azure API key or using an OpenAI API Key, or using Microsoft Entra ID. === Azure API Key & Endpoint Obtain your Azure OpenAI `endpoint` and `api-key` from the Azure OpenAI Service section on the https://portal.azure.com[Azure Portal]. Spring AI defines two configuration properties: 1. `spring.ai.azure.openai.api-key`: Set this to the value of the `API Key` obtained from Azure. 2. `spring.ai.azure.openai.endpoint`: Set this to the endpoint URL obtained when provisioning your model in Azure. You can set these configuration properties in your `application.properties` or `application.yml` file: [source,properties] ---- spring.ai.azure.openai.api-key= spring.ai.azure.openai.endpoint= ---- If you prefer to use environment variables for sensitive information like API keys, you can use Spring Expression Language (SpEL) in your configuration: [source,yaml] ---- # In application.yml spring: ai: azure: openai: api-key: ${AZURE_OPENAI_API_KEY} endpoint: ${AZURE_OPENAI_ENDPOINT} ---- [source,bash] ---- # In your environment or .env file export AZURE_OPENAI_API_KEY= export AZURE_OPENAI_ENDPOINT= ---- === OpenAI Key To authenticate with the OpenAI service (not Azure), provide an OpenAI API key. This will automatically set the endpoint to https://api.openai.com/v1. When 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. In your application configuration: [source,properties] ---- spring.ai.azure.openai.openai-api-key= spring.ai.azure.openai.chat.options.deployment-name= ---- Using environment variables with SpEL: [source,yaml] ---- # In application.yml spring: ai: azure: openai: openai-api-key: ${AZURE_OPENAI_API_KEY} chat: options: deployment-name: ${OPENAI_MODEL_NAME} ---- [source,bash] ---- # In your environment or .env file export AZURE_OPENAI_API_KEY= export OPENAI_MODEL_NAME= ---- === Microsoft Entra ID For 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. Finding 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. NOTE: It is no longer necessary to create a `TokenCredential` bean; it is configured for you automatically. === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the Azure OpenAI Embedding Model. To enable it add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-model-azure-openai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-azure-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Embedding Properties The prefix `spring.ai.azure.openai` is the property prefix to configure the connection to Azure OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.azure.openai.api-key | The Key from Azure AI OpenAI `Keys and Endpoint` section under `Resource Management` | - | spring.ai.azure.openai.endpoint | The endpoint from the Azure AI OpenAI `Keys and Endpoint` section under `Resource Management` | - | spring.ai.azure.openai.openai-api-key | (non Azure) OpenAI API key. Used to authenticate with the OpenAI service, instead of Azure OpenAI. This automatically sets the endpoint to https://api.openai.com/v1. Use either `api-key` or `openai-api-key` property. With this configuration the `spring.ai.azure.openai.embedding.options.deployment-name` is treated as an https://platform.openai.com/docs/models[OpenAi Model] name.| - |==== [NOTE] ==== Enabling and disabling of the embedding auto-configurations are now configured via top level properties with the prefix `spring.ai.model.embedding`. To enable, spring.ai.model.embedding=azure-openai (It is enabled by default) To disable, spring.ai.model.embedding=none (or any value which doesn't match azure-openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.azure.openai.embedding` is the property prefix that configures the `EmbeddingModel` implementation for Azure OpenAI [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.azure.openai.embedding.enabled (Removed and no longer valid) | Enable Azure OpenAI embedding model. | true | spring.ai.model.embedding | Enable Azure OpenAI embedding model. | azure-openai | spring.ai.azure.openai.embedding.metadata-mode | Document content extraction mode | EMBED | 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 | 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. | - |==== TIP: All properties prefixed with `spring.ai.azure.openai.embedding.options` can be overridden at runtime by adding a request specific <> to the `EmbeddingRequest` call. == Runtime Options [[embedding-options]] The `AzureOpenAiEmbeddingOptions` provides the configuration information for the embedding requests. The `AzureOpenAiEmbeddingOptions` offers a builder to create the options. At start time use the `AzureOpenAiEmbeddingModel` constructor to set the default options used for all embedding requests. At run-time you can override the default options, by passing a `AzureOpenAiEmbeddingOptions` instance with your to the `EmbeddingRequest` request. For example to override the default model name for a specific request: [source,java] ---- EmbeddingResponse embeddingResponse = embeddingModel.call( new EmbeddingRequest(List.of("Hello World", "World is big and salvation is near"), AzureOpenAiEmbeddingOptions.builder() .model("Different-Embedding-Model-Deployment-Name") .build())); ---- == Sample Code This will create a `EmbeddingModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the `EmbeddingModel` implementation. [source,application.properties] ---- spring.ai.azure.openai.api-key=YOUR_API_KEY spring.ai.azure.openai.endpoint=YOUR_ENDPOINT spring.ai.azure.openai.embedding.options.model=text-embedding-ada-002 ---- [source,java] ---- @RestController public class EmbeddingController { private final EmbeddingModel embeddingModel; @Autowired public EmbeddingController(EmbeddingModel embeddingModel) { this.embeddingModel = embeddingModel; } @GetMapping("/ai/embedding") public Map embed(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { EmbeddingResponse embeddingResponse = this.embeddingModel.embedForResponse(List.of(message)); return Map.of("embedding", embeddingResponse); } } ---- == Manual Configuration If you prefer not to use the Spring Boot auto-configuration, you can manually configure the `AzureOpenAiEmbeddingModel` in your application. For this add the `spring-ai-azure-openai` dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-azure-openai ---- or to your Gradle `build.gradle` build file. [source,gradle] ---- dependencies { implementation 'org.springframework.ai:spring-ai-azure-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.

The `spring.ai.minimax.embedding.base-url` and `spring.ai.minimax.embedding.api-key` properties if set take precedence over the common properties. Similarly, the `spring.ai.minimax.chat.base-url` and `spring.ai.minimax.chat.api-key` properties if set take precedence over the common properties. This is useful if you want to use different MiniMax accounts for different models and different model endpoints. TIP: All properties prefixed with `spring.ai.minimax.embedding.options` can be overridden at runtime by adding a request specific <> to the `EmbeddingRequest` call. == Runtime Options [[embedding-options]] The 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. The default options can be configured using the `spring.ai.minimax.embedding.options` properties as well. At start-time use the `MiniMaxEmbeddingModel` constructor to set the default options used for all embedding requests. At run-time you can override the default options, using a `MiniMaxEmbeddingOptions` instance as part of your `EmbeddingRequest`. For example to override the default model name for a specific request: [source,java] ---- EmbeddingResponse embeddingResponse = embeddingModel.call( new EmbeddingRequest(List.of("Hello World", "World is big and salvation is near"), MiniMaxEmbeddingOptions.builder() .model("Different-Embedding-Model-Deployment-Name") .build())); ---- == Sample Controller This will create a `EmbeddingModel` implementation that you can inject into your class.

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 | 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 | 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 | spring.ai.ollama.embedding.options.num-keep | - | 4 | spring.ai.ollama.embedding.options.seed | Sets the random number seed to use for generation.

(-1 = infinite generation, -2 = fill context) | -1 | 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 | 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 | 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 | 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 | spring.ai.ollama.embedding.options.typical-p | - | 1.0 | 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 | spring.ai.ollama.embedding.options.temperature | The temperature of the model. Increasing the temperature will make the model answer more creatively. | 0.8 | 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 | spring.ai.ollama.embedding.options.presence-penalty | - | 0.0 | spring.ai.ollama.embedding.options.frequency-penalty | - | 0.0 | spring.ai.ollama.embedding.options.mirostat | Enable Mirostat sampling for controlling perplexity. (default: 0, 0 = disabled, 1 = Mirostat, 2 = Mirostat 2.0) | 0 | 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 | 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 | spring.ai.ollama.embedding.options.penalize-newline | - | true | 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. | - | 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. | - |==== TIP: All properties prefixed with `spring.ai.ollama.embedding.options` can be overridden at runtime by adding a request specific <> to the `EmbeddingRequest` call. == Runtime Options [[embedding-options]] The 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. IMPORTANT: 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. The default options can be configured using the `spring.ai.ollama.embedding.options` properties as well. At start-time use the `OllamaEmbeddingModel(OllamaApi ollamaApi, OllamaEmbeddingOptions defaultOptions)` to configure the default options used for all embedding requests. At run-time you can override the default options, using a `OllamaEmbeddingOptions` instance as part of your `EmbeddingRequest`. For example to override the default model name for a specific request: [source,java] ---- EmbeddingResponse embeddingResponse = embeddingModel.call( new EmbeddingRequest(List.of("Hello World", "World is big and salvation is near"), OllamaEmbeddingOptions.builder() .model("Different-Embedding-Model-Deployment-Name")) .truncates(false) .build()); ---- [[auto-pulling-models]] == Auto-pulling Models Spring AI Ollama can automatically pull models when they are not available in your Ollama instance. This feature is particularly useful for development and testing as well as for deploying your applications to new environments. TIP: You can also pull, by name, any of the thousands, free, link:https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face Models]. There are three strategies for pulling models: * `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. * `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. * `never` (defined in `PullModelStrategy.NEVER`): Never pull the model automatically. CAUTION: 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. All models defined via configuration properties and default options can be automatically pulled at startup time. You can configure the pull strategy, timeout, and maximum number of retries using configuration properties: [source,yaml] ---- spring: ai: ollama: init: pull-model-strategy: always timeout: 60s max-retries: 1 ---- CAUTION: 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. You can initialize additional models at startup, which is useful for models used dynamically at runtime: [source,yaml] ---- spring: ai: ollama: init: pull-model-strategy: always embedding: additional-models: - mxbai-embed-large - nomic-embed-text ---- If you want to apply the pulling strategy only to specific types of models, you can exclude embedding models from the initialization task: [source,yaml] ---- spring: ai: ollama: init: pull-model-strategy: always embedding: include: false ---- This configuration will apply the pulling strategy to all models except embedding models. == HuggingFace Models Ollama can access, out of the box, all https://huggingface.co/models?library=gguf&sort=trending[GGUF Hugging Face] Embedding models. You can pull any of these models by name: `ollama pull hf.co//` or configure the auto-pulling strategy: xref:auto-pulling-models[Auto-pulling Models]: [source] ---- spring.ai.ollama.embedding.options.model=hf.co/mixedbread-ai/mxbai-embed-large-v1 spring.ai.ollama.init.pull-model-strategy=always ---- - `spring.ai.ollama.embedding.options.model`: Specifies the https://huggingface.co/models?library=gguf&sort=trending[Hugging Face GGUF model] to use. - `spring.ai.ollama.init.pull-model-strategy=always`: (optional) Enables automatic model pulling at startup time. For production, you should pre-download the models to avoid delays: `ollama pull hf.co/mixedbread-ai/mxbai-embed-large-v1`. == Sample Controller This will create a `EmbeddingModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the `EmbeddingModel` implementation. [source,java] ---- @RestController public class EmbeddingController { private final EmbeddingModel embeddingModel; @Autowired public EmbeddingController(EmbeddingModel embeddingModel) { this.embeddingModel = embeddingModel; } @GetMapping("/ai/embedding") public Map embed(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { EmbeddingResponse embeddingResponse = this.embeddingModel.embedForResponse(List.of(message)); return Map.of("embedding", embeddingResponse); } } ---- == Manual Configuration If you are not using Spring Boot, you can manually configure the `OllamaEmbeddingModel`. For this add the spring-ai-ollama dependency to your project’s Maven pom.xml or Gradle `build.gradle` build files: [tabs] ====== Maven:: + [source,xml] ---- org.springframework.ai spring-ai-ollama ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-ollama' } ---- ====== TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. NOTE: The `spring-ai-ollama` dependency provides access also to the `OllamaChatModel`. For more information about the `OllamaChatModel` refer to the link:../chat/ollama-chat.html[Ollama Chat Client] section. Next, 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: [source,java] ---- var ollamaApi = OllamaApi.builder().build(); var embeddingModel = new OllamaEmbeddingModel(this.ollamaApi, OllamaEmbeddingOptions.builder() .model(OllamaModel.MISTRAL.id()) .build()); EmbeddingResponse embeddingResponse = this.embeddingModel.call( new EmbeddingRequest(List.of("Hello World", "World is big and salvation is near"), OllamaEmbeddingOptions.builder() .model("chroma/all-minilm-l6-v2-f32")) .truncate(false) .build()); ---- The `OllamaEmbeddingOptions` provides the configuration information for all embedding requests. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/embeddings/onnx.adoc ================================================ = Transformers (ONNX) Embeddings The `TransformersEmbeddingModel` is an `EmbeddingModel` implementation that locally computes https://www.sbert.net/examples/applications/computing-embeddings/README.html#sentence-embeddings-with-transformers[sentence embeddings] using a selected https://www.sbert.net/[sentence transformer]. You can use any link:https://huggingface.co/spaces/mteb/leaderboard[HuggingFace Embedding model]. It uses https://www.sbert.net/docs/pretrained_models.html[pre-trained] transformer models, serialized into the https://onnx.ai/[Open Neural Network Exchange (ONNX)] format. The https://djl.ai/[Deep Java Library] and the Microsoft https://onnxruntime.ai/docs/get-started/with-java.html[ONNX Java Runtime] libraries are applied to run the ONNX models and compute the embeddings in Java. == Prerequisites To run things in Java, we need to *serialize the Tokenizer and the Transformer Model* into `ONNX` format. Serialize with optimum-cli - One, quick, way to achieve this, is to use the https://huggingface.co/docs/optimum/exporters/onnx/usage_guides/export_a_model#exporting-a-model-to-onnx-using-the-cli[optimum-cli] command line tool. The following snippet prepares a python virtual environment, installs the required packages and serializes (e.g. exports) the specified model using `optimum-cli` : [source,bash] ---- python3 -m venv venv source ./venv/bin/activate (venv) pip install --upgrade pip (venv) pip install optimum onnx onnxruntime sentence-transformers (venv) optimum-cli export onnx --model sentence-transformers/all-MiniLM-L6-v2 onnx-output-folder ---- The snippet exports the https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2[sentence-transformers/all-MiniLM-L6-v2] transformer into the `onnx-output-folder` folder. The latter includes the `tokenizer.json` and `model.onnx` files used by the embedding model. In place of the all-MiniLM-L6-v2 you can pick any huggingface transformer identifier or provide direct file path. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the ONNX Transformer Embedding Model. To enable it add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-model-transformers ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-transformers' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To configure it, use the `spring.ai.embedding.transformer.*` properties. For example, add this to your _application.properties_ file to configure the client with the https://huggingface.co/intfloat/e5-small-v2[intfloat/e5-small-v2] text embedding model: ---- spring.ai.embedding.transformer.onnx.modelUri=https://huggingface.co/intfloat/e5-small-v2/resolve/main/model.onnx spring.ai.embedding.transformer.tokenizer.uri=https://huggingface.co/intfloat/e5-small-v2/raw/main/tokenizer.json ---- The complete list of supported properties are: === Embedding Properties [NOTE] ==== Enabling and disabling of the embedding auto-configurations are now configured via top level properties with the prefix `spring.ai.model.embedding`. To enable, spring.ai.model.embedding=transformers (It is enabled by default) To disable, spring.ai.model.embedding=none (or any value which doesn't match transformers) This change is done to allow configuration of multiple models. ==== [cols="3*"", stripes=even] |=== | Property | Description | Default | spring.ai.embedding.transformer.enabled (Removed and no longer valid) | Enable the Transformer Embedding model. | true | spring.ai.model.embedding | Enable the Transformer Embedding model. | transformers | spring.ai.embedding.transformer.tokenizer.uri | URI of a pre-trained HuggingFaceTokenizer created by the ONNX engine (e.g. tokenizer.json). | onnx/all-MiniLM-L6-v2/tokenizer.json | spring.ai.embedding.transformer.tokenizer.options | HuggingFaceTokenizer options such as '`addSpecialTokens`', '`modelMaxLength`', '`truncation`', '`padding`', '`maxLength`', '`stride`', '`padToMultipleOf`'. Leave empty to fallback to the defaults. | empty | spring.ai.embedding.transformer.cache.enabled | Enable remote Resource caching. | true | spring.ai.embedding.transformer.cache.directory | Directory path to cache remote resources, such as the ONNX models | ${java.io.tmpdir}/spring-ai-onnx-model | spring.ai.embedding.transformer.onnx.modelUri | Existing, pre-trained ONNX model. | onnx/all-MiniLM-L6-v2/model.onnx | spring.ai.embedding.transformer.onnx.modelOutputName | The ONNX model's output node name, which we'll use for embedding calculation. | last_hidden_state | spring.ai.embedding.transformer.onnx.gpuDeviceId | The GPU device ID to execute on. Only applicable if >= 0. Ignored otherwise.(Requires additional onnxruntime_gpu dependency) | -1 | spring.ai.embedding.transformer.metadataMode | Specifies what parts of the Documents content and metadata will be used for computing the embeddings. | NONE |=== === Errors and special cases [NOTE] ==== If you see an error like `Caused by: ai.onnxruntime.OrtException: Supplied array is ragged,..`, you need to also enable the tokenizer padding in `application.properties` as follows: ---- spring.ai.embedding.transformer.tokenizer.options.padding=true ---- ==== [NOTE] ==== If you get an error like `The generative output names don't contain expected: last_hidden_state. Consider one of the available model outputs: token_embeddings, ....`, you need to set the model output name to a correct value per your models. Consider the names listed in the error message. For example: ---- spring.ai.embedding.transformer.onnx.modelOutputName=token_embeddings ---- ==== [NOTE] ==== If you get an error like `ai.onnxruntime.OrtException: Error code - ORT_FAIL - message: Deserialize tensor onnx::MatMul_10319 failed.GetFileLength for ./model.onnx_data failed:Invalid fd was supplied: -1`, that means that you model is larger than 2GB and is serialized in two files: `model.onnx` and `model.onnx_data`. The `model.onnx_data` is called link:https://onnx.ai/onnx/repo-docs/ExternalData.html#external-data[External Data] and is expected to be under the same directory of the `model.onnx`. Currently the only workaround is to copy the large `model.onnx_data` in the folder you run your Boot application. ==== [NOTE] ==== If you get an error like `ai.onnxruntime.OrtException: Error code - ORT_EP_FAIL - message: Failed to find CUDA shared provider`, that means that you are using the GPU parameters `spring.ai.embedding.transformer.onnx.gpuDeviceId` , but the onnxruntime_gpu dependency are missing. ---- com.microsoft.onnxruntime onnxruntime_gpu ---- Please select the appropriate onnxruntime_gpu version based on the CUDA version(link:https://onnxruntime.ai/docs/get-started/with-java.html[ONNX Java Runtime]). ==== == Manual Configuration If you are not using Spring Boot, you can manually configure the Onnx Transformers Embedding Model. For this add the `spring-ai-transformers` dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-transformers ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. then create a new `TransformersEmbeddingModel` instance and use the `setTokenizerResource(tokenizerJsonUri)` and `setModelResource(modelOnnxUri)` methods to set the URIs of the exported `tokenizer.json` and `model.onnx` files. (`classpath:`, `file:` or `https:` URI schemas are supported). If the model is not explicitly set, `TransformersEmbeddingModel` defaults to https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2[sentence-transformers/all-MiniLM-L6-v2]: [cols="2*"] |=== | Dimensions | 384 | Avg. performance | 58.80 | Speed | 14200 sentences/sec | Size | 80MB |=== The following snippet illustrates how to use the `TransformersEmbeddingModel` manually: [source,java] ---- TransformersEmbeddingModel embeddingModel = new TransformersEmbeddingModel(); // (optional) defaults to classpath:/onnx/all-MiniLM-L6-v2/tokenizer.json embeddingModel.setTokenizerResource("classpath:/onnx/all-MiniLM-L6-v2/tokenizer.json"); // (optional) defaults to classpath:/onnx/all-MiniLM-L6-v2/model.onnx embeddingModel.setModelResource("classpath:/onnx/all-MiniLM-L6-v2/model.onnx"); // (optional) defaults to ${java.io.tmpdir}/spring-ai-onnx-model // Only the http/https resources are cached by default. embeddingModel.setResourceCacheDirectory("/tmp/onnx-zoo"); // (optional) Set the tokenizer padding if you see an errors like: // "ai.onnxruntime.OrtException: Supplied array is ragged, ..." embeddingModel.setTokenizerOptions(Map.of("padding", "true")); embeddingModel.afterPropertiesSet(); List> embeddings = this.embeddingModel.embed(List.of("Hello world", "World is big")); ---- NOTE: If you create an instance of `TransformersEmbeddingModel` manually, you must call the `afterPropertiesSet()` method after setting the properties and before using the client. The first `embed()` call downloads the large ONNX model and caches it on the local file system. Therefore, the first call might take longer than usual. Use the `#setResourceCacheDirectory()` method to set the local folder where the ONNX models as stored. The default cache folder is `${java.io.tmpdir}/spring-ai-onnx-model`. It is more convenient (and preferred) to create the TransformersEmbeddingModel as a `Bean`. Then you don't have to call the `afterPropertiesSet()` manually. [source,java] ---- @Bean public EmbeddingModel embeddingModel() { return new TransformersEmbeddingModel(); } ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/embeddings/openai-embeddings.adoc ================================================ = OpenAI Embeddings Spring AI supports the OpenAI's text embeddings models. OpenAI’s text embeddings measure the relatedness of text strings. An embedding is a vector (list) of floating point numbers. The distance between two vectors measures their relatedness. Small distances suggest high relatedness and large distances suggest low relatedness. [NOTE] ==== Starting 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]. ==== == Prerequisites You will need to create an API with OpenAI to access OpenAI embeddings models. Create 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]. The 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. You can set this configuration property in your `application.properties` file: [source,properties] ---- spring.ai.openai.api-key= ---- For enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference an environment variable: [source,yaml] ---- # In application.yml spring: ai: openai: api-key: ${OPENAI_API_KEY} ---- [source,bash] ---- # In your environment or .env file export OPENAI_API_KEY= ---- You can also set this configuration programmatically in your application code: [source,java] ---- // Retrieve API key from a secure source or environment variable String apiKey = System.getenv("OPENAI_API_KEY"); ---- === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the OpenAI Embedding Model. To enable it add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Embedding Properties ==== Retry Properties The prefix `spring.ai.retry` is used as the property prefix that lets you configure the retry mechanism for the OpenAI Embedding model. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.retry.max-attempts | Maximum number of retry attempts. | 10 | spring.ai.retry.backoff.initial-interval | Initial sleep duration for the exponential backoff policy. | 2 sec. | spring.ai.retry.backoff.multiplier | Backoff interval multiplier. | 5 | spring.ai.retry.backoff.max-interval | Maximum backoff duration. | 3 min. | spring.ai.retry.on-client-errors | If false, throw a NonTransientAiException, and do not attempt retry for `4xx` client error codes | false | spring.ai.retry.exclude-on-http-codes | List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException). | empty | spring.ai.retry.on-http-codes | List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException). | empty |==== ==== Connection Properties The prefix `spring.ai.openai` is used as the property prefix that lets you connect to OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.base-url | The URL to connect to | +https://api.openai.com+ | spring.ai.openai.api-key | The API Key | - | spring.ai.openai.organization-id | Optionally you can specify which organization used for an API request. | - | spring.ai.openai.project-id | Optionally, you can specify which project is used for an API request. | - |==== TIP: 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. Usage from these API requests will count as usage for the specified organization and project. ==== Configuration Properties [NOTE] ==== Enabling and disabling of the embedding auto-configurations are now configured via top level properties with the prefix `spring.ai.model.embedding`. To enable, spring.ai.model.embedding=openai (It is enabled by default) To disable, spring.ai.model.embedding=none (or any value which doesn't match openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.openai.embedding` is property prefix that configures the `EmbeddingModel` implementation for OpenAI. [cols="3,5,1", stripes=even] |==== | Property | Description | Default | spring.ai.openai.embedding.enabled (Required and no longer valid) | Enable OpenAI embedding model. | true | spring.ai.model.embedding | Enable OpenAI embedding model. | openai | spring.ai.openai.embedding.base-url | Optional overrides the spring.ai.openai.base-url to provide embedding specific url | - | spring.ai.openai.embedding.embeddings-path | The path to append to the base-url | `/v1/embeddings` | spring.ai.openai.embedding.api-key | Optional overrides the spring.ai.openai.api-key to provide embedding specific api-key | - | spring.ai.openai.embedding.organization-id | Optionally you can specify which organization used for an API request. | - | spring.ai.openai.embedding.project-id | Optionally, you can specify which project is used for an API request. | - | spring.ai.openai.embedding.metadata-mode | Document content extraction mode. | EMBED | spring.ai.openai.embedding.options.model | The model to use | text-embedding-ada-002 (other options: text-embedding-3-large, text-embedding-3-small) | spring.ai.openai.embedding.options.encodingFormat | The format to return the embeddings in. Can be either float or base64. | - | spring.ai.openai.embedding.options.user | A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. | - | spring.ai.openai.embedding.options.dimensions | The number of dimensions the resulting output embeddings should have. Only supported in `text-embedding-3` and later models. | - |==== NOTE: You can override the common `spring.ai.openai.base-url` and `spring.ai.openai.api-key` for the `ChatModel` and `EmbeddingModel` implementations. The `spring.ai.openai.embedding.base-url` and `spring.ai.openai.embedding.api-key` properties if set take precedence over the common properties. Similarly, the `spring.ai.openai.chat.base-url` and `spring.ai.openai.chat.api-key` properties if set take precedence over the common properties. This is useful if you want to use different OpenAI accounts for different models and different model endpoints. TIP: All properties prefixed with `spring.ai.openai.embedding.options` can be overridden at runtime by adding a request specific <> to the `EmbeddingRequest` call. == Runtime Options [[embedding-options]] The https://github.com/spring-projects/spring-ai/blob/main/models/spring-ai-openai/src/main/java/org/springframework/ai/openai/OpenAiEmbeddingOptions.java[OpenAiEmbeddingOptions.java] provides the OpenAI configurations, such as the model to use and etc. The default options can be configured using the `spring.ai.openai.embedding.options` properties as well. At start-time use the `OpenAiEmbeddingModel` constructor to set the default options used for all embedding requests. At run-time you can override the default options, using a `OpenAiEmbeddingOptions` instance as part of your `EmbeddingRequest`. For example to override the default model name for a specific request: [source,java] ---- EmbeddingResponse embeddingResponse = embeddingModel.call( new EmbeddingRequest(List.of("Hello World", "World is big and salvation is near"), OpenAiEmbeddingOptions.builder() .model("Different-Embedding-Model-Deployment-Name") .build())); ---- == Sample Controller This will create a `EmbeddingModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the `EmbeddingModel` implementation. [source,application.properties] ---- spring.ai.openai.api-key=YOUR_API_KEY spring.ai.openai.embedding.options.model=text-embedding-ada-002 ---- [source,java] ---- @RestController public class EmbeddingController { private final EmbeddingModel embeddingModel; @Autowired public EmbeddingController(EmbeddingModel embeddingModel) { this.embeddingModel = embeddingModel; } @GetMapping("/ai/embedding") public Map embed(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { EmbeddingResponse embeddingResponse = this.embeddingModel.embedForResponse(List.of(message)); return Map.of("embedding", embeddingResponse); } } ---- == Manual Configuration If you are not using Spring Boot, you can manually configure the OpenAI Embedding Model. For this add the `spring-ai-openai` dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-openai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. NOTE: The `spring-ai-openai` dependency provides access also to the `OpenAiChatModel`. For more information about the `OpenAiChatModel` refer to the link:../chat/openai-chat.html[OpenAI Chat Client] section. Next, create an `OpenAiEmbeddingModel` instance and use it to compute the similarity between two input texts: [source,java] ---- var openAiApi = OpenAiApi.builder() .apiKey(System.getenv("OPENAI_API_KEY")) .build(); var embeddingModel = new OpenAiEmbeddingModel( this.openAiApi, MetadataMode.EMBED, OpenAiEmbeddingOptions.builder() .model("text-embedding-ada-002") .user("user-6") .build(), RetryUtils.DEFAULT_RETRY_TEMPLATE); EmbeddingResponse embeddingResponse = this.embeddingModel .embedForResponse(List.of("Hello World", "World is big and salvation is near")); ---- The `OpenAiEmbeddingOptions` provides the configuration information for the embedding requests.

Embeddings are a numeric representation of text. They are used to represent words and sentences as vectors, an array of numbers. Embeddings can be used to find similar pieces of text, by comparing the similarity of the numeric vectors using a distance measure, or they can be used as input features for other machine learning models, since most algorithms can't use text directly. Many pre-trained LLMs can be used to generate embeddings from text within PostgresML. You can browse all the https://huggingface.co/models?library=sentence-transformers[models] available to find the best solution on Hugging Face. == Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the Azure PostgresML Embedding Model. To enable it add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-model-postgresml-embedding ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-postgresml-embedding' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Use the `spring.ai.postgresml.embedding.options.*` properties to configure your `PostgresMlEmbeddingModel`. links === Embedding Properties [NOTE] ==== Enabling and disabling of the embedding auto-configurations are now configured via top level properties with the prefix `spring.ai.model.embedding`. To enable, spring.ai.model.embedding=postgresml (It is enabled by default) To disable, spring.ai.model.embedding=none (or any value which doesn't match postgresml) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.postgresml.embedding` is property prefix that configures the `EmbeddingModel` implementation for PostgresML embeddings.

At run-time you can override the default options, using a `PostgresMlEmbeddingOptions` in your `EmbeddingRequest`. For example to override the default model name for a specific request: [source,java] ---- EmbeddingResponse embeddingResponse = embeddingModel.call( new EmbeddingRequest(List.of("Hello World", "World is big and salvation is near"), PostgresMlEmbeddingOptions.builder() .transformer("intfloat/e5-small") .vectorType(VectorType.PG_ARRAY) .kwargs(Map.of("device", "gpu")) .build())); ---- == Sample Controller This will create a `EmbeddingModel` implementation that you can inject into your class. Here is an example of a simple `@Controller` class that uses the `EmbeddingModel` implementation. [source,application.properties] ---- spring.ai.postgresml.embedding.options.transformer=distilbert-base-uncased spring.ai.postgresml.embedding.options.vectorType=PG_ARRAY spring.ai.postgresml.embedding.options.metadataMode=EMBED spring.ai.postgresml.embedding.options.kwargs.device=cpu ---- [source,java] ---- @RestController public class EmbeddingController { private final EmbeddingModel embeddingModel; @Autowired public EmbeddingController(EmbeddingModel embeddingModel) { this.embeddingModel = embeddingModel; } @GetMapping("/ai/embedding") public Map embed(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) { EmbeddingResponse embeddingResponse = this.embeddingModel.embedForResponse(List.of(message)); return Map.of("embedding", embeddingResponse); } } ---- == Manual configuration Instead of using the Spring Boot auto-configuration, you can create the `PostgresMlEmbeddingModel` manually. For this add the `spring-ai-postgresml` dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-postgresml ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-postgresml' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.

EmbeddingResponse embeddingResponse = this.embeddingModel .embedForResponse(List.of("Hello World", "World is big and salvation is near")); ---- NOTE: When created manually, you must call the `afterPropertiesSet()` after setting the properties and before using the client. It is more convenient (and preferred) to create the PostgresMlEmbeddingModel as a `@Bean`. Then you don’t have to call the `afterPropertiesSet()` manually: [source,java] ---- @Bean public EmbeddingModel embeddingModel(JdbcTemplate jdbcTemplate) { return new PostgresMlEmbeddingModel(jdbcTemplate, PostgresMlEmbeddingOptions.builder() .... .build()); } ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/embeddings/qianfan-embeddings.adoc ================================================ = QianFan Embeddings This functionality has been moved to the Spring AI Community repository.

This document describes how to create a multimodal embedding using the Vertex AI link:https://cloud.google.com/vertex-ai/generative-ai/docs/embeddings/get-multimodal-embeddings[Multimodal embeddings API]. The multimodal embeddings model generates 1408-dimension vectors based on the input you provide, which can include a combination of image, text, and video data. The embedding vectors can then be used for subsequent tasks like image classification or video content moderation. The image embedding vector and text embedding vector are in the same semantic space with the same dimensionality. Consequently, these vectors can be used interchangeably for use cases like searching image by text, or searching video by image.

Embeddings work by converting text, image, and video into arrays of floating point numbers, called vectors. These vectors are designed to capture the meaning of the text, images, and videos. The length of the embedding array is called the vector's dimensionality. By 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. The `EmbeddingModel` interface is designed for straightforward integration with embedding models in AI and machine learning. Its primary function is to convert text into numerical vectors, commonly referred to as embeddings. These embeddings are crucial for various tasks such as semantic analysis and text classification. The design of the EmbeddingModel interface centers around two primary goals: * *Portability*: This interface ensures easy adaptability across various embedding models. It allows developers to switch between different embedding techniques or models with minimal code changes. This design aligns with Spring's philosophy of modularity and interchangeability. * *Simplicity*: EmbeddingModel simplifies the process of converting text to embeddings. By 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. == API Overview The 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. As 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. The 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. Following diagram illustrates the Embedding API and its relationship with the Spring AI Model API and the Embedding Models: image:embeddings-api.jpg[title=Embeddings API,align=center,width=900] === EmbeddingModel This section provides a guide to the `EmbeddingModel` interface and associated classes. [source,java] ---- public interface EmbeddingModel extends Model { @Override EmbeddingResponse call(EmbeddingRequest request); /** * Embeds the given document's content into a vector. * @param document the document to embed. * @return the embedded vector. */ float[] embed(Document document); /** * Extracts the text content from a Document to be used for embedding. * By default, returns Document.getText(). Implementations that support * MetadataMode should override this to return * Document.getFormattedContent(MetadataMode) so that metadata is * included in the text sent to the embedding API. */ default String getEmbeddingContent(Document document) { return document.getText(); } /** * Embeds the given text into a vector. * @param text the text to embed. * @return the embedded vector. */ default float[] embed(String text) { Assert.notNull(text, "Text must not be null"); return this.embed(List.of(text)).iterator().next(); } /** * Embeds a batch of texts into vectors. * @param texts list of texts to embed. * @return list of list of embedded vectors. */ default List embed(List texts) { Assert.notNull(texts, "Texts must not be null"); return this.call(new EmbeddingRequest(texts, EmbeddingOptions.EMPTY)) .getResults() .stream() .map(Embedding::getOutput) .toList(); } /** * Embeds a batch of texts into vectors and returns the {@link EmbeddingResponse}. * @param texts list of texts to embed. * @return the embedding response. */ default EmbeddingResponse embedForResponse(List texts) { Assert.notNull(texts, "Texts must not be null"); return this.call(new EmbeddingRequest(texts, EmbeddingOptions.EMPTY)); } /** * @return the number of dimensions of the embedded vectors. It is generative * specific. */ default int dimensions() { return embed("Test String").size(); } } ---- The embed methods offer various options for converting text into embeddings, accommodating single strings, structured `Document` objects, or batches of text. Multiple shortcut methods are provided for embedding text, including the `embed(String text)` method, which takes a single string and returns the corresponding embedding vector. All shortcuts are implemented around the `call` method, which is the primary method for invoking the embedding model. The `getEmbeddingContent(Document)` method controls how text is extracted from a `Document` before embedding. By default it returns `Document.getText()`, but embedding model implementations that support `MetadataMode` (such as OpenAI, Azure OpenAI, and Mistral AI) override this method to return `Document.getFormattedContent(MetadataMode)`, ensuring that document metadata is included in the text sent to the embedding API when configured. This method is used by the batched embedding path that vector stores rely on. Typically the embedding returns a lists of floats, representing the embeddings in a numerical vector format. The `embedForResponse` method provides a more comprehensive output, potentially including additional information about the embeddings. The dimensions method is a handy tool for developers to quickly ascertain the size of the embedding vectors, which is important for understanding the embedding space and for subsequent processing steps. ==== EmbeddingRequest The `EmbeddingRequest` is a `ModelRequest` that takes a list of text objects and optional embedding request options. The following listing shows a truncated version of the EmbeddingRequest class, excluding constructors and other utility methods: [source,java] ---- public class EmbeddingRequest implements ModelRequest> { private final List inputs; private final EmbeddingOptions options; // other methods omitted } ---- ==== EmbeddingResponse The structure of the `EmbeddingResponse` class is as follows: [source,java] ---- public class EmbeddingResponse implements ModelResponse { private List embeddings; private EmbeddingResponseMetadata metadata = new EmbeddingResponseMetadata(); // other methods omitted } ---- The `EmbeddingResponse` class holds the AI Model's output, with each `Embedding` instance containing the result vector data from a single text input. The `EmbeddingResponse` class also carries a `EmbeddingResponseMetadata` metadata about the AI Model's response. ==== Embedding The `Embedding` represents a single embedding vector. [source,java] ---- public class Embedding implements ModelResult { private float[] embedding; private Integer index; private EmbeddingResultMetadata metadata; // other methods omitted } ---- == Available Implementations [[available-implementations]] Internally the various `EmbeddingModel` implementations use different low-level libraries and APIs to perform the embedding tasks. The following are some of the available implementations of the `EmbeddingModel` implementations: * xref:api/embeddings/openai-embeddings.adoc[Spring AI OpenAI Embeddings] * xref:api/embeddings/azure-openai-embeddings.adoc[Spring AI Azure OpenAI Embeddings] * xref:api/embeddings/ollama-embeddings.adoc[Spring AI Ollama Embeddings] * xref:api/embeddings/onnx.adoc[Spring AI Transformers (ONNX) Embeddings] * xref:api/embeddings/postgresml-embeddings.adoc[Spring AI PostgresML Embeddings] * xref:api/embeddings/bedrock-cohere-embedding.adoc[Spring AI Bedrock Cohere Embeddings] * xref:api/embeddings/bedrock-titan-embedding.adoc[Spring AI Bedrock Titan Embeddings] * xref:api/embeddings/vertexai-embeddings-text.adoc[Spring AI VertexAI Embeddings] * xref:api/embeddings/mistralai-embeddings.adoc[Spring AI Mistral AI Embeddings] ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/etl-pipeline.adoc ================================================ = ETL Pipeline The Extract, Transform, and Load (ETL) framework serves as the backbone of data processing within the Retrieval Augmented Generation (RAG) use case. The ETL pipeline orchestrates the flow from raw data sources to a structured vector store, ensuring data is in the optimal format for retrieval by the AI model. The RAG use case is text to augment the capabilities of generative models by retrieving relevant information from a body of data to enhance the quality and relevance of the generated output. == API Overview The ETL pipelines creates, transforms and stores `Document` instances. image::spring-ai-document1-api.jpg[Spring AI Message API, width=400, align="center"] The `Document` class contains text, metadata and optionally additional media types like images, audio and video. There are three main components of the ETL pipeline, * `DocumentReader` that implements `Supplier>` * `DocumentTransformer` that implements `Function, List>` * `DocumentWriter` that implements `Consumer>` The `Document` class content is created from PDFs, text files and other document types with the help of `DocumentReader`. To construct a simple ETL pipeline, you can chain together an instance of each type. image::etl-pipeline.jpg[align="center"] Let's say we have the following instances of those three ETL types * `PagePdfDocumentReader` an implementation of `DocumentReader` * `TokenTextSplitter` an implementation of `DocumentTransformer` * `VectorStore` an implementation of `DocumentWriter` To 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. [source,java] ---- vectorStore.accept(tokenTextSplitter.apply(pdfReader.get())); ---- Alternatively, you can use method names that are more naturally expressive for the domain [source,java] ---- vectorStore.write(tokenTextSplitter.split(pdfReader.read())); ---- == ETL Interfaces The ETL pipeline is composed of the following interfaces and implementations. Detailed ETL class diagram is shown in the <> section. === DocumentReader Provides a source of documents from diverse origins. [source,java] ---- public interface DocumentReader extends Supplier> { default List read() { return get(); } } ---- === DocumentTransformer Transforms a batch of documents as part of the processing workflow. [source,java] ---- public interface DocumentTransformer extends Function, List> { default List transform(List transform) { return apply(transform); } } ---- === DocumentWriter Manages the final stage of the ETL process, preparing documents for storage. ```java public interface DocumentWriter extends Consumer> { default void write(List documents) { accept(documents); } } ``` [[etl-class-diagram]] === ETL Class Diagram The following class diagram illustrates the ETL interfaces and implementations. // image::etl-class-diagram.jpg[align="center", width="800px"] image::etl-class-diagram.jpg[align="center"] == DocumentReaders === JSON The `JsonReader` processes JSON documents, converting them into a list of `Document` objects. ==== Example [source,java] ---- @Component class MyJsonReader { private final Resource resource; MyJsonReader(@Value("classpath:bikes.json") Resource resource) { this.resource = resource; } List loadJsonAsDocuments() { JsonReader jsonReader = new JsonReader(this.resource, "description", "content"); return jsonReader.get(); } } ---- ==== Constructor Options The `JsonReader` provides several constructor options: 1. `JsonReader(Resource resource)` 2. `JsonReader(Resource resource, String... jsonKeysToUse)` 3. `JsonReader(Resource resource, JsonMetadataGenerator jsonMetadataGenerator, String... jsonKeysToUse)` ==== Parameters * `resource`: A Spring `Resource` object pointing to the JSON file. * `jsonKeysToUse`: An array of keys from the JSON that should be used as the text content in the resulting `Document` objects. * `jsonMetadataGenerator`: An optional `JsonMetadataGenerator` to create metadata for each `Document`. ==== Behavior The `JsonReader` processes JSON content as follows: * It can handle both JSON arrays and single JSON objects. * For each JSON object (either in an array or a single object): ** It extracts the content based on the specified `jsonKeysToUse`. ** If no keys are specified, it uses the entire JSON object as content. ** It generates metadata using the provided `JsonMetadataGenerator` (or an empty one if not provided). ** It creates a `Document` object with the extracted content and metadata. ==== Using JSON Pointers The `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. ===== The `get(String pointer)` method [source,java] ---- public List get(String pointer) ---- This method allows you to use a JSON Pointer to retrieve a specific part of the JSON document. ====== Parameters * `pointer`: A JSON Pointer string (as defined in RFC 6901) to locate the desired element within the JSON structure. ====== Return Value * Returns a `List` containing the documents parsed from the JSON element located by the pointer. ====== Behavior * The method uses the provided JSON Pointer to navigate to a specific location in the JSON structure. * If the pointer is valid and points to an existing element: ** For a JSON object: it returns a list with a single Document. ** For a JSON array: it returns a list of Documents, one for each element in the array. * If the pointer is invalid or points to a non-existent element, it throws an `IllegalArgumentException`. ====== Example [source,java] ---- JsonReader jsonReader = new JsonReader(resource, "description"); List documents = this.jsonReader.get("/store/books/0"); ---- ==== Example JSON Structure [source,json] ---- [ { "id": 1, "brand": "Trek", "description": "A high-performance mountain bike for trail riding." }, { "id": 2, "brand": "Cannondale", "description": "An aerodynamic road bike for racing enthusiasts." } ] ---- In 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. ==== Notes * The `JsonReader` uses Jackson for JSON parsing. * It can handle large JSON files efficiently by using streaming for arrays. * If multiple keys are specified in `jsonKeysToUse`, the content will be a concatenation of the values for those keys. * The reader is flexible and can be adapted to various JSON structures by customizing the `jsonKeysToUse` and `JsonMetadataGenerator`. === Text The `TextReader` processes plain text documents, converting them into a list of `Document` objects. ==== Example [source,java] ---- @Component class MyTextReader { private final Resource resource; MyTextReader(@Value("classpath:text-source.txt") Resource resource) { this.resource = resource; } List loadText() { TextReader textReader = new TextReader(this.resource); textReader.getCustomMetadata().put("filename", "text-source.txt"); return textReader.read(); } } ---- ==== Constructor Options The `TextReader` provides two constructor options: 1. `TextReader(String resourceUrl)` 2. `TextReader(Resource resource)` ==== Parameters * `resourceUrl`: A string representing the URL of the resource to be read. * `resource`: A Spring `Resource` object pointing to the text file. ==== Configuration * `setCharset(Charset charset)`: Sets the character set used for reading the text file. Default is UTF-8. * `getCustomMetadata()`: Returns a mutable map where you can add custom metadata for the documents. ==== Behavior The `TextReader` processes text content as follows: * It reads the entire content of the text file into a single `Document` object. * The content of the file becomes the content of the `Document`. * Metadata is automatically added to the `Document`: ** `charset`: The character set used to read the file (default: "UTF-8"). ** `source`: The filename of the source text file. * Any custom metadata added via `getCustomMetadata()` is included in the `Document`. ==== Notes * The `TextReader` reads the entire file content into memory, so it may not be suitable for very large files. * If you need to split the text into smaller chunks, you can use a text splitter like `TokenTextSplitter` after reading the document: [source,java] ---- List documents = textReader.get(); List splitDocuments = TokenTextSplitter.builder().build().apply(this.documents); ---- * The reader uses Spring's `Resource` abstraction, allowing it to read from various sources (classpath, file system, URL, etc.). * Custom metadata can be added to all documents created by the reader using the `getCustomMetadata()` method. === HTML (JSoup) The `JsoupDocumentReader` processes HTML documents, converting them into a list of `Document` objects using the JSoup library. ==== Dependencies Add the dependency to your project using Maven or Gradle. [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-jsoup-document-reader ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-jsoup-document-reader' } ---- ====== ==== Example [source,java] ---- @Component class MyHtmlReader { private final Resource resource; MyHtmlReader(@Value("classpath:/my-page.html") Resource resource) { this.resource = resource; } List loadHtml() { JsoupDocumentReaderConfig config = JsoupDocumentReaderConfig.builder() .selector("article p") // Extract paragraphs within

tags .charset("ISO-8859-1") // Use ISO-8859-1 encoding .includeLinkUrls(true) // Include link URLs in metadata .metadataTags(List.of("author", "date")) // Extract author and date meta tags .additionalMetadata("source", "my-page.html") // Add custom metadata .build(); JsoupDocumentReader reader = new JsoupDocumentReader(this.resource, config); return reader.get(); } } ---- The `JsoupDocumentReaderConfig` allows you to customize the behavior of the `JsoupDocumentReader`: * `charset`: Specifies the character encoding of the HTML document (defaults to "UTF-8"). * `selector`: A JSoup CSS selector to specify which elements to extract text from (defaults to "body"). * `separator`: The string used to join text from multiple selected elements (defaults to "\n"). * `allElements`: If `true`, extracts all text from the `` element, ignoring the `selector` (defaults to `false`). * `groupByElement`: If `true`, creates a separate `Document` for each element matched by the `selector` (defaults to `false`). * `includeLinkUrls`: If `true`, extracts absolute link URLs and adds them to the metadata (defaults to `false`). * `metadataTags`: A list of `` tag names to extract content from (defaults to `["description", "keywords"]`). * `additionalMetadata`: Allows you to add custom metadata to all created `Document` objects. ==== Sample Document: my-page.html [source,html] ---- My Web Page

---- Behavior: The `JsoupDocumentReader` processes the HTML content and creates `Document` objects based on the configuration: * The `selector` determines which elements are used for text extraction. * If `allElements` is `true`, all text within the `` is extracted into a single `Document`. * If `groupByElement` is `true`, each element matching the `selector` creates a separate `Document`. * If neither `allElements` nor `groupByElement` is `true`, text from all elements matching the `selector` is joined using the `separator`. * The document title, content from specified `` tags, and (optionally) link URLs are added to the `Document` metadata. * The base URI, for resolving relative links, will be extracted from URL resources. The reader preserves the text content of the selected elements, but removes any HTML tags within them. === Markdown The `MarkdownDocumentReader` processes Markdown documents, converting them into a list of `Document` objects. ==== Dependencies Add the dependency to your project using Maven or Gradle. [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-markdown-document-reader ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-markdown-document-reader' } ---- ====== ==== Example [source,java] ---- @Component class MyMarkdownReader { private final Resource resource; MyMarkdownReader(@Value("classpath:code.md") Resource resource) { this.resource = resource; } List loadMarkdown() { MarkdownDocumentReaderConfig config = MarkdownDocumentReaderConfig.builder() .withHorizontalRuleCreateDocument(true) .withIncludeCodeBlock(false) .withIncludeBlockquote(false) .withAdditionalMetadata("filename", "code.md") .build(); MarkdownDocumentReader reader = new MarkdownDocumentReader(this.resource, config); return reader.get(); } } ---- The `MarkdownDocumentReaderConfig` allows you to customize the behavior of the MarkdownDocumentReader: * `horizontalRuleCreateDocument`: When set to `true`, horizontal rules in the Markdown will create new `Document` objects. * `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. * `includeBlockquote`: When set to `true`, blockquotes will be included in the same `Document` as the surrounding text. When `false`, blockquotes create separate `Document` objects. * `additionalMetadata`: Allows you to add custom metadata to all created `Document` objects. ==== Sample Document: code.md [source,markdown] ---- This is a Java sample application: ```java package com.example.demo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } } ``` Markdown also provides the possibility to `use inline code formatting throughout` the entire sentence. --- Another possibility is to set block code without specific highlighting: ``` ./mvnw spring-javaformat:apply ``` ---- Behavior: The MarkdownDocumentReader processes the Markdown content and creates Document objects based on the configuration: * Headers become metadata in the Document objects. * Paragraphs become the content of Document objects. * Code blocks can be separated into their own Document objects or included with surrounding text. * Blockquotes can be separated into their own Document objects or included with surrounding text. * Horizontal rules can be used to split the content into separate Document objects. The reader preserves formatting like inline code, lists, and text styling within the content of the Document objects. === PDF Page The `PagePdfDocumentReader` uses Apache PdfBox library to parse PDF documents. ==== Dependencies Add the dependency to your project using Maven or Gradle. [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-pdf-document-reader ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-pdf-document-reader' } ---- ====== ==== Example [source,java] ---- @Component public class MyPagePdfDocumentReader { List getDocsFromPdf() { PagePdfDocumentReader pdfReader = new PagePdfDocumentReader("classpath:/sample1.pdf", PdfDocumentReaderConfig.builder() .withPageTopMargin(0) .withPageExtractedTextFormatter(ExtractedTextFormatter.builder() .withNumberOfTopTextLinesToDelete(0) .build()) .withPagesPerDocument(1) .build()); return pdfReader.read(); } } ---- === PDF Paragraph The `ParagraphPdfDocumentReader` uses the PDF catalog (e.g. TOC) information to split the input PDF into text paragraphs and output a single `Document` per paragraph. NOTE: Not all PDF documents contain the PDF catalog. ==== Dependencies Add the dependency to your project using Maven or Gradle. [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-pdf-document-reader ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-pdf-document-reader' } ---- ====== ==== Example [source,java] ---- @Component public class MyPagePdfDocumentReader { List getDocsFromPdfWithCatalog() { ParagraphPdfDocumentReader pdfReader = new ParagraphPdfDocumentReader("classpath:/sample1.pdf", PdfDocumentReaderConfig.builder() .withPageTopMargin(0) .withPageExtractedTextFormatter(ExtractedTextFormatter.builder() .withNumberOfTopTextLinesToDelete(0) .build()) .withPagesPerDocument(1) .build()); return pdfReader.read(); } } ---- === Tika (DOCX, PPTX, HTML...) The `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]. ==== Dependencies Add the dependency to your project using Maven or Gradle. [tabs] ====== Maven:: + [source, xml] ---- org.springframework.ai spring-ai-tika-document-reader ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-tika-document-reader' } ---- ====== ==== Example [source,java] ---- @Component class MyTikaDocumentReader { private final Resource resource; MyTikaDocumentReader(@Value("classpath:/word-sample.docx") Resource resource) { this.resource = resource; } List loadText() { TikaDocumentReader tikaDocumentReader = new TikaDocumentReader(this.resource); return tikaDocumentReader.read(); } } ---- == Transformers === TextSplitter The `TextSplitter` an abstract base class that helps divides documents to fit the AI model's context window. === TokenTextSplitter The `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`. ==== Usage ===== Basic Usage [source,java] ---- @Component class MyTokenTextSplitter { public List splitDocuments(List documents) { TokenTextSplitter splitter = TokenTextSplitter.builder().build(); return splitter.apply(documents); } public List splitCustomized(List documents) { TokenTextSplitter splitter = TokenTextSplitter.builder() .withChunkSize(1000) .withMinChunkSizeChars(400) .withMinChunkLengthToEmbed(10) .withMaxNumChunks(5000) .withKeepSeparator(true) .build(); return splitter.apply(documents); } } ---- ===== Custom Encoding Type You can configure the encoding type used for tokenization. This is useful when working with models that use different tokenizers: [source,java] ---- TokenTextSplitter splitter = TokenTextSplitter.builder() .withEncodingType(EncodingType.O200K_BASE) .withChunkSize(1000) .build(); ---- ===== Custom Punctuation Marks You can customize the punctuation marks used for splitting text into semantically meaningful chunks. This is particularly useful for internationalization: [source,java] ---- @Component class MyInternationalTextSplitter { public List splitChineseText(List documents) { // Use Chinese punctuation marks TokenTextSplitter splitter = TokenTextSplitter.builder() .withChunkSize(800) .withMinChunkSizeChars(350) .withPunctuationMarks(List.of('。', '？', '！', '；')) // Chinese punctuation .build(); return splitter.apply(documents); } public List splitWithCustomMarks(List documents) { // Mix of English and other punctuation marks TokenTextSplitter splitter = TokenTextSplitter.builder() .withChunkSize(800) .withPunctuationMarks(List.of('.', '?', '!', '\n', ';', ':', '。')) .build(); return splitter.apply(documents); } } ---- ==== Configuration Use `TokenTextSplitter.builder()` to create instances. All constructors are deprecated in favor of the builder. ==== Parameters * `encodingType`: The tokenizer encoding type to use (default: `CL100K_BASE`). Supported values include `CL100K_BASE`, `P50K_BASE`, and `O200K_BASE`. * `chunkSize`: The target size of each text chunk in tokens (default: 800). * `minChunkSizeChars`: The minimum size of each text chunk in characters (default: 350). * `minChunkLengthToEmbed`: The minimum length of a chunk to be included (default: 5). * `maxNumChunks`: The maximum number of chunks to generate from a text (default: 10000). * `keepSeparator`: Whether to keep separators (like newlines) in the chunks (default: true). * `punctuationMarks`: List of characters to use as sentence boundaries for splitting (default: `.`, `?`, `!`, `\n`). ==== Behavior The `TokenTextSplitter` processes text content as follows: 1. It encodes the input text into tokens using the CL100K_BASE encoding. 2. It splits the encoded text into chunks based on the `chunkSize`. 3. For each chunk: a. It decodes the chunk back into text. 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`. c. If a break point is found, it truncates the chunk at that point. d. It trims the chunk and optionally removes newline characters based on the `keepSeparator` setting. e. If the resulting chunk is longer than `minChunkLengthToEmbed`, it's added to the output. 4. This process continues until all tokens are processed or `maxNumChunks` is reached. 5. Any remaining text is added as a final chunk if it's longer than `minChunkLengthToEmbed`. IMPORTANT: 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. ==== Example [source,java] ---- Document doc1 = new Document("This is a long piece of text that needs to be split into smaller chunks for processing.", Map.of("source", "example.txt")); Document doc2 = new Document("Another document with content that will be split based on token count.", Map.of("source", "example2.txt")); TokenTextSplitter splitter = TokenTextSplitter.builder().build(); List splitDocuments = splitter.apply(List.of(doc1, doc2)); for (Document doc : splitDocuments) { System.out.println("Chunk: " + doc.getContent()); System.out.println("Metadata: " + doc.getMetadata()); } ---- ==== Notes * The `TokenTextSplitter` uses the CL100K_BASE encoding from the `jtokkit` library, which is compatible with newer OpenAI models. * The splitter attempts to create semantically meaningful chunks by breaking at sentence boundaries where possible. * Metadata from the original documents is preserved and copied to all chunks derived from that document. * The content formatter (if set) from the original document is also copied to the derived chunks if `copyContentFormatter` is set to `true` (default behavior). * 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. * *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. * *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. * *Extensibility*: The `getLastPunctuationIndex(String)` method is `protected`, allowing subclasses to override the punctuation detection logic for specialized use cases. * *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. === ContentFormatTransformer Ensures uniform content formats across all documents. === KeywordMetadataEnricher The `KeywordMetadataEnricher` is a `DocumentTransformer` that uses a generative AI model to extract keywords from document content and add them as metadata. ==== Usage [source,java] ---- @Component class MyKeywordEnricher { private final ChatModel chatModel; MyKeywordEnricher(ChatModel chatModel) { this.chatModel = chatModel; } List enrichDocuments(List documents) { KeywordMetadataEnricher enricher = KeywordMetadataEnricher.builder(chatModel) .keywordCount(5) .build(); // Or use custom templates KeywordMetadataEnricher enricher = KeywordMetadataEnricher.builder(chatModel) .keywordsTemplate(YOUR_CUSTOM_TEMPLATE) .build(); return enricher.apply(documents); } } ---- ==== Constructor Options The `KeywordMetadataEnricher` provides two constructor options: 1. `KeywordMetadataEnricher(ChatModel chatModel, int keywordCount)`: To use the default template and extract a specified number of keywords. 2. `KeywordMetadataEnricher(ChatModel chatModel, PromptTemplate keywordsTemplate)`: To use a custom template for keyword extraction. ==== Behavior The `KeywordMetadataEnricher` processes documents as follows: 1. For each input document, it creates a prompt using the document's content. 2. It sends this prompt to the provided `ChatModel` to generate keywords. 3. The generated keywords are added to the document's metadata under the key "excerpt_keywords". 4. The enriched documents are returned. ==== Customization You can use the default template or customize the template through the keywordsTemplate parameter. The default template is: [source,java] ---- \{context_str}. Give %s unique keywords for this document. Format as comma separated. Keywords: ---- Where `+{context_str}+` is replaced with the document content, and `%s` is replaced with the specified keyword count. ==== Example [source,java] ---- ChatModel chatModel = // initialize your chat model KeywordMetadataEnricher enricher = KeywordMetadataEnricher.builder(chatModel) .keywordCount(5) .build(); // Or use custom templates KeywordMetadataEnricher enricher = KeywordMetadataEnricher.builder(chatModel) .keywordsTemplate(new PromptTemplate("Extract 5 important keywords from the following text and separate them with commas:\n{context_str}")) .build(); Document doc = new Document("This is a document about artificial intelligence and its applications in modern technology."); List enrichedDocs = enricher.apply(List.of(this.doc)); Document enrichedDoc = this.enrichedDocs.get(0); String keywords = (String) this.enrichedDoc.getMetadata().get("excerpt_keywords"); System.out.println("Extracted keywords: " + keywords); ---- ==== Notes * The `KeywordMetadataEnricher` requires a functioning `ChatModel` to generate keywords. * The keyword count must be 1 or greater. * The enricher adds the "excerpt_keywords" metadata field to each processed document. * The generated keywords are returned as a comma-separated string. * This enricher is particularly useful for improving document searchability and for generating tags or categories for documents. * In the Builder pattern, if the `keywordsTemplate` parameter is set, the `keywordCount` parameter will be ignored. === SummaryMetadataEnricher The `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). ==== Usage [source,java] ---- @Configuration class EnricherConfig { @Bean public SummaryMetadataEnricher summaryMetadata(OpenAiChatModel aiClient) { return new SummaryMetadataEnricher(aiClient, List.of(SummaryType.PREVIOUS, SummaryType.CURRENT, SummaryType.NEXT)); } } @Component class MySummaryEnricher { private final SummaryMetadataEnricher enricher; MySummaryEnricher(SummaryMetadataEnricher enricher) { this.enricher = enricher; } List enrichDocuments(List documents) { return this.enricher.apply(documents); } } ---- ==== Constructor The `SummaryMetadataEnricher` provides two constructors: 1. `SummaryMetadataEnricher(ChatModel chatModel, List summaryTypes)` 2. `SummaryMetadataEnricher(ChatModel chatModel, List summaryTypes, String summaryTemplate, MetadataMode metadataMode)` ==== Parameters * `chatModel`: The AI model used for generating summaries. * `summaryTypes`: A list of `SummaryType` enum values indicating which summaries to generate (PREVIOUS, CURRENT, NEXT). * `summaryTemplate`: A custom template for summary generation (optional). * `metadataMode`: Specifies how to handle document metadata when generating summaries (optional). ==== Behavior The `SummaryMetadataEnricher` processes documents as follows: 1. For each input document, it creates a prompt using the document's content and the specified summary template. 2. It sends this prompt to the provided `ChatModel` to generate a summary. 3. Depending on the specified `summaryTypes`, it adds the following metadata to each document: * `section_summary`: Summary of the current document. * `prev_section_summary`: Summary of the previous document (if available and requested). * `next_section_summary`: Summary of the next document (if available and requested). 4. The enriched documents are returned. ==== Customization The summary generation prompt can be customized by providing a custom `summaryTemplate`. The default template is: [source,java] ---- """ Here is the content of the section: {context_str} Summarize the key topics and entities of the section. Summary: """ ---- ==== Example [source,java] ---- ChatModel chatModel = // initialize your chat model SummaryMetadataEnricher enricher = new SummaryMetadataEnricher(chatModel, List.of(SummaryType.PREVIOUS, SummaryType.CURRENT, SummaryType.NEXT)); Document doc1 = new Document("Content of document 1"); Document doc2 = new Document("Content of document 2"); List enrichedDocs = enricher.apply(List.of(this.doc1, this.doc2)); // Check the metadata of the enriched documents for (Document doc : enrichedDocs) { System.out.println("Current summary: " + doc.getMetadata().get("section_summary")); System.out.println("Previous summary: " + doc.getMetadata().get("prev_section_summary")); System.out.println("Next summary: " + doc.getMetadata().get("next_section_summary")); } ---- The provided example demonstrates the expected behavior: * For a list of two documents, both documents receive a `section_summary`. * The first document receives a `next_section_summary` but no `prev_section_summary`. * The second document receives a `prev_section_summary` but no `next_section_summary`. * The `section_summary` of the first document matches the `prev_section_summary` of the second document. * The `next_section_summary` of the first document matches the `section_summary` of the second document. ==== Notes * The `SummaryMetadataEnricher` requires a functioning `ChatModel` to generate summaries. * The enricher can handle document lists of any size, properly handling edge cases for the first and last documents. * This enricher is particularly useful for creating context-aware summaries, allowing for better understanding of document relationships in a sequence. * The `MetadataMode` parameter allows control over how existing metadata is incorporated into the summary generation process. == Writers === File The `FileDocumentWriter` is a `DocumentWriter` implementation that writes the content of a list of `Document` objects into a file. ==== Usage [source,java] ---- @Component class MyDocumentWriter { public void writeDocuments(List documents) { FileDocumentWriter writer = new FileDocumentWriter("output.txt", true, MetadataMode.ALL, false); writer.accept(documents); } } ---- ==== Constructors The `FileDocumentWriter` provides three constructors: 1. `FileDocumentWriter(String fileName)` 2. `FileDocumentWriter(String fileName, boolean withDocumentMarkers)` 3. `FileDocumentWriter(String fileName, boolean withDocumentMarkers, MetadataMode metadataMode, boolean append)` ==== Parameters * `fileName`: The name of the file to write the documents to. * `withDocumentMarkers`: Whether to include document markers in the output (default: false). * `metadataMode`: Specifies what document content to be written to the file (default: MetadataMode.NONE). * `append`: If true, data will be written to the end of the file rather than the beginning (default: false). ==== Behavior The `FileDocumentWriter` processes documents as follows: 1. It opens a FileWriter for the specified file name. 2. For each document in the input list: a. If `withDocumentMarkers` is true, it writes a document marker including the document index and page numbers. b. It writes the formatted content of the document based on the specified `metadataMode`. 3. The file is closed after all documents have been written. ==== Document Markers When `withDocumentMarkers` is set to true, the writer includes markers for each document in the following format: [source] ---- ### Doc: [index], pages:[start_page_number,end_page_number] ---- ==== Metadata Handling The writer uses two specific metadata keys: * `page_number`: Represents the starting page number of the document. * `end_page_number`: Represents the ending page number of the document. These are used when writing document markers. ==== Example [source,java] ---- List documents = // initialize your documents FileDocumentWriter writer = new FileDocumentWriter("output.txt", true, MetadataMode.ALL, true); writer.accept(documents); ---- This will write all documents to "output.txt", including document markers, using all available metadata, and appending to the file if it already exists. ==== Notes * The writer uses `FileWriter`, so it writes text files with the default character encoding of the operating system. * If an error occurs during writing, a `RuntimeException` is thrown with the original exception as its cause. * The `metadataMode` parameter allows control over how existing metadata is incorporated into the written content. * This writer is particularly useful for debugging or creating human-readable outputs of document collections. === VectorStore Provides integration with various vector stores. See xref:api/vectordbs.adoc[Vector DB Documentation] for a full listing. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/generic-model.adoc ================================================ [[generic-model-api]] = Generic Model API In order to provide a foundation for all AI Models, the Generic Model API was created. This makes it easy to contribute new AI Model support to Spring AI by following a common pattern. The following sections walk through this API. == Class Diagram image::spring-ai-generic-model-api.jpg[width=900, align="center"] == Model The `Model` interface provides a generic API for invoking AI models. It is designed to handle the interaction with various types of AI models by abstracting the process of sending requests and receiving responses. The interface uses Java generics to accommodate different types of requests and responses, enhancing flexibility and adaptability across different AI model implementations. The interface is defined below: [source,java] ---- public interface Model, TRes extends ModelResponse> { /** * Executes a method call to the AI model. * @param request the request object to be sent to the AI model * @return the response from the AI model */ TRes call(TReq request); } ---- == StreamingModel The `StreamingModel` interface provides a generic API for invoking an AI model with streaming response. It abstracts the process of sending requests and receiving a streaming response. The interface uses Java generics to accommodate different types of requests and responses, enhancing flexibility and adaptability across different AI model implementations. [source,java] ---- public interface StreamingModel, TResChunk extends ModelResponse> { /** * Executes a method call to the AI model. * @param request the request object to be sent to the AI model * @return the streaming response from the AI model */ Flux stream(TReq request); } ---- == ModelRequest The `ModelRequest` interface represents a request to an AI model. It encapsulates the necessary information required to interact with an AI model, including instructions or inputs (of generic type `T`) and additional model options. It provides a standardized way to send requests to AI models, ensuring that all necessary details are included and can be easily managed. [source,java] ---- public interface ModelRequest { /** * Retrieves the instructions or input required by the AI model. * @return the instructions or input required by the AI model */ T getInstructions(); // required input /** * Retrieves the customizable options for AI model interactions. * @return the customizable options for AI model interactions */ ModelOptions getOptions(); } ---- == ModelOptions The `ModelOptions` interface represents the customizable options for AI model interactions. This marker interface allows for the specification of various settings and parameters that can influence the behavior and output of AI models. It is designed to provide flexibility and adaptability in different AI scenarios, ensuring that the AI models can be fine-tuned according to specific requirements. [source,java] ---- public interface ModelOptions { } ---- == ModelResponse The `ModelResponse` interface represents the response received from an AI model. This interface provides methods to access the main result or a list of results generated by the AI model, along with the response metadata. It serves as a standardized way to encapsulate and manage the output from AI models, ensuring easy retrieval and processing of the generated information. [source,java] ---- public interface ModelResponse> { /** * Retrieves the result of the AI model. * @return the result generated by the AI model */ T getResult(); /** * Retrieves the list of generated outputs by the AI model. * @return the list of generated outputs */ List getResults(); /** * Retrieves the response metadata associated with the AI model's response. * @return the response metadata */ ResponseMetadata getMetadata(); } ---- == ModelResult The `ModelResult` interface provides methods to access the main output of the AI model and the metadata associated with this result. It is designed to offer a standardized and comprehensive way to handle and interpret the outputs generated by AI models. [source,java] ---- public interface ModelResult { /** * Retrieves the output generated by the AI model. * @return the output generated by the AI model */ T getOutput(); /** * Retrieves the metadata associated with the result of an AI model. * @return the metadata associated with the result */ ResultMetadata getMetadata(); } ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/image/azure-openai-image.adoc ================================================ = Azure OpenAI Image Generation Spring AI supports the gpt-image-1-mini image generation model from Azure OpenAI. == Prerequisites Obtain your Azure OpenAI `endpoint` and `api-key` from the Azure OpenAI Service section on the link:https://portal.azure.com[Azure Portal]. Spring AI defines two configuration properties: 1. `spring.ai.azure.openai.api-key`: Set this to the value of the `API Key` obtained from Azure. 2. `spring.ai.azure.openai.endpoint`: Set this to the endpoint URL obtained when provisioning your model in Azure. You can set these configuration properties in your `application.properties` file: [source,properties] ---- spring.ai.azure.openai.api-key= spring.ai.azure.openai.endpoint= ---- For enhanced security when handling sensitive information like API keys, you can use Spring Expression Language (SpEL) to reference custom environment variables: [source,yaml] ---- # In application.yml spring: ai: azure: openai: api-key: ${AZURE_OPENAI_API_KEY} endpoint: ${AZURE_OPENAI_ENDPOINT} ---- [source,bash] ---- # In your environment or .env file export AZURE_OPENAI_API_KEY= export AZURE_OPENAI_ENDPOINT= ---- You can also set these configurations programmatically in your application code: [source,java] ---- // Retrieve API key and endpoint from secure sources or environment variables String apiKey = System.getenv("AZURE_OPENAI_API_KEY"); String endpoint = System.getenv("AZURE_OPENAI_ENDPOINT"); ---- === Deployment Name To use run Azure AI applications, create an Azure AI Deployment through the [Azure AI Portal](https://oai.azure.com/portal). In Azure, each client must specify a `Deployment Name` to connect to the Azure OpenAI service. It's essential to understand that the `Deployment Name` is different from the model you choose to deploy For instance, a deployment named 'MyImgAiDeployment' could be configured to use 'gpt-image-1-mini' model. For now, to keep things simple, you can create a deployment using the following settings: Deployment Name: `MyImgAiDeployment` Model Name: `gpt-image-1-mini` This Azure configuration will align with the default configurations of the Spring Boot Azure AI Starter and its Autoconfiguration feature. If you use a different Deployment Name, update the configuration property accordingly: ``` spring.ai.azure.openai.image.options.deployment-name= ``` The different deployment structures of Azure OpenAI and OpenAI leads to a property in the Azure OpenAI client library named `deploymentOrModelName`. This is because in OpenAI there is no `Deployment Name`, only a `Model Name`. === Add Repositories and BOM Spring AI artifacts are published in Maven Central and Spring Snapshot repositories. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add these repositories to your build system. To 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. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the Azure OpenAI Chat Client. To enable it add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-model-azure-openai ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-model-azure-openai' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Image Generation Properties [NOTE] ==== Enabling and disabling of the image auto-configurations are now configured via top level properties with the prefix `spring.ai.model.image`. To enable, spring.ai.model.image=azure-openai (It is enabled by default) To disable, spring.ai.model.image=none (or any value which doesn't match azure-openai) This change is done to allow configuration of multiple models. ==== The prefix `spring.ai.azure.openai.image` is the property prefix that lets you configure the `ImageModel` implementation for Azure OpenAI.

On 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. At runtime you can override the default options by adding request-specific options to the `ImagePrompt` call. For example, to use the gpt-image-1-mini model with a custom size: [source,java] ---- ImageResponse response = azureOpenAiImageModel.call( new ImagePrompt("A light cream colored mini golden doodle", AzureOpenAiImageOptions.builder() .model("gpt-image-1-mini") .deploymentName("gpt-image-1-mini") .height(1024) .width(1024) .build()) ); ---- TIP: 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()]. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/image/openai-image.adoc ================================================ = OpenAI Image Generation Spring AI supports DALL-E, the Image generation model from OpenAI.

This 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. Additionally, 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. It manages the complexity of request preparation and response parsing, offering a direct and simplified API interaction for image-generation functionalities. The Spring Image Model API is built on top of the Spring AI `Generic Model API`, providing image-specific abstractions and implementations. == API Overview This section provides a guide to the Spring Image Model API interface and associated classes. == Image Model Here 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: [source,java] ---- @FunctionalInterface public interface ImageModel extends Model { ImageResponse call(ImagePrompt request); } ---- === ImagePrompt The 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. The following listing shows a truncated version of the `ImagePrompt` class, excluding constructors and other utility methods: [source,java] ---- public class ImagePrompt implements ModelRequest> { private final List messages; private ImageOptions imageModelOptions; @Override public List getInstructions() {...} @Override public ImageOptions getOptions() {...} // constructors and utility methods omitted } ---- ==== ImageMessage The `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. [source,java] ---- public class ImageMessage { private String text; private Float weight; public String getText() {...} public Float getWeight() {...} // constructors and utility methods omitted } ---- ==== ImageOptions Represents 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. The `ImageOptions` interface is defined as follows: [source,java] ---- public interface ImageOptions extends ModelOptions { Integer getN(); String getModel(); Integer getWidth(); Integer getHeight(); String getResponseFormat(); // openai - url or base64 : stability ai byte[] or base64 } ---- Additionally, 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. This 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`. === ImageResponse The structure of the `ImageResponse` class is as follows: [source,java] ---- public class ImageResponse implements ModelResponse { private final ImageResponseMetadata imageResponseMetadata; private final List imageGenerations; @Override public ImageGeneration getResult() { // get the first result } @Override public List getResults() {...} @Override public ImageResponseMetadata getMetadata() {...} // other methods omitted } ---- The 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. The `ImageResponse` class also carries a `ImageResponseMetadata` object holding metadata about the AI Model's response. === ImageGeneration Finally, 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: [source,java] ---- public class ImageGeneration implements ModelResult { private ImageGenerationMetadata imageGenerationMetadata; private Image image; @Override public Image getOutput() {...} @Override public ImageGenerationMetadata getMetadata() {...} // other methods omitted } ---- == Available Implementations `ImageModel` implementations are provided for the following Model providers: * xref:api/image/openai-image.adoc[OpenAI Image Generation] * xref:api/image/azure-openai-image.adoc[Azure OpenAI Image Generation] * xref:api/image/qianfan-image.adoc[QianFan Image Generation] * xref:api/image/stabilityai-image.adoc[StabilityAI Image Generation] == API Docs You can find the Javadoc https://docs.spring.io/spring-ai/docs/current-SNAPSHOT/[here]. == Feedback and Contributions The project's https://github.com/spring-projects/spring-ai/discussions[GitHub discussions] is a great place to send feedback. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/index.adoc ================================================ = Spring AI API == Introduction The Spring AI API covers a wide range of functionalities. Each major feature is detailed in its own dedicated section. To provide an overview, the following key functionalities are available: === AI Model API Portable `Model API` across AI providers for `Chat`, `Text to Image`, `Audio Transcription`, `Text to Speech`, and `Embedding` models. Both `synchronous` and `stream` API options are supported. Dropping down to access model specific features is also supported. image::model-hierarchy.jpg[Model hierarchy, width=900, align="center"] With support for AI Models from OpenAI, Microsoft, Amazon, Google, Amazon Bedrock and more. image::spring-ai-chat-completions-clients.jpg[align="center", width="800px"] === Vector Store API Portable `Vector Store API` across multiple providers, including a novel `SQL-like metadata filter API` that is also portable. Support for 14 vector databases are available. === Tool Calling API Spring AI makes it easy to have the AI model invoke your services as `@Tool`-annotated methods or POJO `java.util.Function` objects. image::tools/tool-calling-01.jpg[The main sequence of actions for tool calling, width=500, align="center"] Check the Spring AI xref::api/tools.adoc[Tool Calling] documentation. === Auto Configuration Spring Boot Auto Configuration and Starters for AI Models and Vector Stores. === ETL Data Engineering ETL framework for Data Engineering. This provides the basis of loading data into a vector database, helping implement the Retrieval Augmented Generation pattern that enables you to bring your data to the AI model to incorporate into its response. image::etl-pipeline.jpg[align="center"] == Feedback and Contributions The project's https://github.com/spring-projects/spring-ai/discussions[GitHub discussions] is a great place to send feedback. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/mcp/mcp-annotations-client.adoc ================================================ = MCP Client Annotations The MCP Client Annotations provide a declarative way to implement MCP client handlers using Java annotations. These annotations simplify the handling of server notifications and client-side operations. [IMPORTANT] **All MCP client annotations MUST include a `clients` parameter** to associate the handler with a specific MCP client connection. The `clients` must match the connection name configured in your application properties. == Client Annotations === @McpLogging The `@McpLogging` annotation handles logging message notifications from MCP servers. ==== Basic Usage [source,java] ---- @Component public class LoggingHandler { @McpLogging(clients = "my-mcp-server") public void handleLoggingMessage(LoggingMessageNotification notification) { System.out.println("Received log: " + notification.level() + " - " + notification.data());

return new ElicitResult(ElicitResult.Action.ACCEPT, userData); }).timeout(Duration.ofSeconds(30)) .onErrorReturn(new ElicitResult(ElicitResult.Action.CANCEL, null)); } ---- === @McpProgress The `@McpProgress` annotation handles progress notifications for long-running operations. ==== Basic Usage [source,java] ---- @Component public class ProgressHandler { @McpProgress(clients = "my-mcp-server") public void handleProgressNotification(ProgressNotification notification) { double percentage = notification.progress() * 100; System.out.println(String.format("Progress: %.2f%% - %s", percentage, notification.message())); } } ---- ==== With Individual Parameters [source,java] ---- @McpProgress(clients = "my-mcp-server") public void handleProgressWithDetails( String progressToken, double progress, Double total, String message) { if (total != null) { System.out.println(String.format("[%s] %.0f/%.0f - %s", progressToken, progress, total, message)); } else { System.out.println(String.format("[%s] %.2f%% - %s", progressToken, progress * 100, message)); } // Update UI progress bar updateProgressBar(progressToken, progress); } ---- ==== Client-Specific Progress [source,java] ---- @McpProgress(clients = "long-running-server") public void handleLongRunningProgress(ProgressNotification notification) { // Track progress for specific server progressTracker.update("long-running-server", notification); // Send notifications if needed if (notification.progress() >= 1.0) { notifyCompletion(notification.progressToken()); } } ---- === @McpToolListChanged The `@McpToolListChanged` annotation handles notifications when the server's tool list changes. ==== Basic Usage [source,java] ---- @Component public class ToolListChangedHandler { @McpToolListChanged(clients = "tool-server") public void handleToolListChanged(List updatedTools) { System.out.println("Tool list updated: " + updatedTools.size() + " tools available"); // Update local tool registry toolRegistry.updateTools(updatedTools); // Log new tools for (McpSchema.Tool tool : updatedTools) { System.out.println(" - " + tool.name() + ": " + tool.description()); } } } ---- ==== Async Handling [source,java] ---- @McpToolListChanged(clients = "tool-server") public Mono handleAsyncToolListChanged(List updatedTools) { return Mono.fromRunnable(() -> { // Process tool list update asynchronously processToolListUpdate(updatedTools); // Notify interested components eventBus.publish(new ToolListUpdatedEvent(updatedTools)); }).then(); } ---- ==== Client-Specific Tool Updates [source,java] ---- @McpToolListChanged(clients = "dynamic-server") public void handleDynamicServerToolUpdate(List updatedTools) { // Handle tools from a specific server that frequently changes its tools dynamicToolManager.updateServerTools("dynamic-server", updatedTools); // Re-evaluate tool availability reevaluateToolCapabilities(); } ---- === @McpResourceListChanged The `@McpResourceListChanged` annotation handles notifications when the server's resource list changes. ==== Basic Usage [source,java] ---- @Component public class ResourceListChangedHandler { @McpResourceListChanged(clients = "resource-server") public void handleResourceListChanged(List updatedResources) { System.out.println("Resources updated: " + updatedResources.size()); // Update resource cache resourceCache.clear(); for (McpSchema.Resource resource : updatedResources) { resourceCache.register(resource); } } } ---- ==== With Resource Analysis [source,java] ---- @McpResourceListChanged(clients = "resource-server") public void analyzeResourceChanges(List updatedResources) { // Analyze what changed Set newUris = updatedResources.stream() .map(McpSchema.Resource::uri) .collect(Collectors.toSet()); Set removedUris = previousUris.stream() .filter(uri -> !newUris.contains(uri)) .collect(Collectors.toSet()); if (!removedUris.isEmpty()) { handleRemovedResources(removedUris); } // Update tracking previousUris = newUris;

}) .then(); } ---- == Spring Boot Integration With Spring Boot auto-configuration, client handlers are automatically detected and registered: [source,java] ---- @SpringBootApplication public class McpClientApplication { public static void main(String[] args) { SpringApplication.run(McpClientApplication.class, args); } } @Component public class MyClientHandlers { @McpLogging(clients = "my-server") public void handleLogs(LoggingMessageNotification notification) { // Handle logs } @McpSampling(clients = "my-server") public CreateMessageResult handleSampling(CreateMessageRequest request) { // Handle sampling } @McpProgress(clients = "my-server") public void handleProgress(ProgressNotification notification) { // Handle progress } } ---- The auto-configuration will: 1. Scan for beans with MCP client annotations 2. Create appropriate specifications 3. Register them with the MCP client 4. Support both sync and async implementations 5. Handle multiple clients with client-specific handlers == Configuration Properties Configure the client annotation scanner and client connections: [source,yaml] ---- spring: ai: mcp: client: type: SYNC # or ASYNC annotation-scanner: enabled: true # Configure client connections - the connection names become clients values sse: connections: my-server: # This becomes the clients url: http://localhost:8080 tool-server: # Another clients url: http://localhost:8081 stdio: connections: local-server: # This becomes the clients command: /path/to/mcp-server args: - --mode=production ---- [IMPORTANT] The `clients` parameter in annotations must match the connection names defined in your configuration. In the example above, valid `clients` values would be: `"my-server"`, `"tool-server"`, and `"local-server"`. == Usage with MCP Client The annotated handlers are automatically integrated with the MCP client: [source,java] ---- @Autowired private List mcpClients; // The clients will automatically use your annotated handlers based on clients // No manual registration needed - handlers are matched to clients by name ---- For each MCP client connection, handlers with matching `clients` will be automatically registered and invoked when the corresponding events occur. == Additional Resources * xref:api/mcp/mcp-annotations-overview.adoc[MCP Annotations Overview] * xref:api/mcp/mcp-annotations-server.adoc[Server Annotations] * xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters] * xref:api/mcp/mcp-client-boot-starter-docs.adoc[MCP Client Boot Starter] ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/mcp/mcp-annotations-examples.adoc ================================================ = MCP Annotations Examples This page provides comprehensive examples of using MCP annotations in Spring AI applications. == Complete Application Examples === Simple Calculator Server A complete example of an MCP server providing calculator tools: [source,java] ---- @SpringBootApplication public class CalculatorServerApplication { public static void main(String[] args) { SpringApplication.run(CalculatorServerApplication.class, args);

It simplifies the creation and registration of MCP server methods and client handlers through a clean, declarative approach using Java annotations. The MCP Annotations enable developers to create and register MCP operation handlers using declarative annotations. This approach simplifies implementing MCP server and client functionality by reducing boilerplate code and improving maintainability. This 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. == Architecture The MCP Annotations module consists of: === Server Annotations For MCP Servers, the following annotations are provided: * `@McpTool` - Implements MCP tools with automatic JSON schema generation * `@McpResource` - Provides access to resources via URI templates * `@McpPrompt` - Generates prompt messages * `@McpComplete` - Provides auto-completion functionality === Client Annotations For MCP Clients, the following annotations are provided: * `@McpLogging` - Handles logging message notifications * `@McpSampling` - Handles sampling requests * `@McpElicitation` - Handles elicitation requests for gathering additional information * `@McpProgress` - Handles progress notifications during long-running operations * `@McpToolListChanged` - Handles tool list change notifications * `@McpResourceListChanged` - Handles resource list change notifications * `@McpPromptListChanged` - Handles prompt list change notifications === Special Parameters and Annotations * `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.** * `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.** * `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 * `@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. * `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. * `MetaProvider` - Interface implemented to supply `_meta` field data for tool, prompt, and resource declarations. Referenced via the `metaProvider` attribute of `@McpTool`, `@McpPrompt`, and `@McpResource`. == Getting Started === Dependencies Add the MCP annotations dependency to your project: [source,xml] ---- org.springframework.ai spring-ai-mcp-annotations ---- The MCP annotations are automatically included when you use any of the MCP Boot Starters: * `spring-ai-starter-mcp-client` * `spring-ai-starter-mcp-client-webflux` * `spring-ai-starter-mcp-server` * `spring-ai-starter-mcp-server-webflux` * `spring-ai-starter-mcp-server-webmvc` === Configuration The annotation scanning is enabled by default when using the MCP Boot Starters.

These annotations simplify the creation of tools, resources, prompts, and completion handlers. == Server Annotations === @McpTool The `@McpTool` annotation marks a method as an MCP tool implementation with automatic JSON schema generation. ==== Basic Usage [source,java] ---- @Component public class CalculatorTools { @McpTool(name = "add", description = "Add two numbers together") public int add( @McpToolParam(description = "First number", required = true) int a, @McpToolParam(description = "Second number", required = true) int b) { return a + b; } } ---- ==== Annotation Attributes The `@McpTool` annotation supports the following attributes: [cols="1,1,3"] |=== |Attribute |Default |Description |`name` |method name |The tool identifier. Defaults to the method name if not provided. |`description` |method name |Human-readable description of the tool. |`title` |`""` |Intended for UI and end-user contexts — optimized to be human-readable. If not provided, `name` is used for display. (Precedence: `annotations.title` > `title` > `name`) |`generateOutputSchema` |`false` |If `true`, automatically generates a JSON output schema for non-primitive return types. |`annotations` |`@McpAnnotations` |Additional hints for clients (see tool annotations below). |`metaProvider` |`DefaultMetaProvider.class` |Class implementing `MetaProvider` that supplies data for the `_meta` field in the tool declaration. |=== ==== Tool Annotations (Hints) [source,java] ---- @McpTool(name = "calculate-area", description = "Calculate the area of a rectangle", title = "Rectangle Area Calculator", generateOutputSchema = true, annotations = @McpTool.McpAnnotations( title = "Rectangle Area Calculator", readOnlyHint = true, destructiveHint = false, idempotentHint = true )) public AreaResult calculateRectangleArea( @McpToolParam(description = "Width", required = true) double width, @McpToolParam(description = "Height", required = true) double height) { return new AreaResult(width * height, "square units"); } ---- The `McpAnnotations` nested annotation provides client hints: [cols="1,1,3"] |=== |Hint |Default |Description |`title` |`""` |Human-readable title for the tool. |`readOnlyHint` |`false` |If `true`, the tool does not modify its environment. |`destructiveHint` |`true` |If `true`, the tool may perform destructive updates (meaningful only when `readOnlyHint == false`). |`idempotentHint` |`false` |If `true`, calling with the same arguments has no additional effect (meaningful only when `readOnlyHint == false`). |`openWorldHint` |`true` |If `true`, the tool may interact with external entities (e.g., web search). If `false`, the domain is closed. |=== ==== With Request Context Tools can access the request context for advanced operations: [source,java] ---- @McpTool(name = "process-data", description = "Process data with request context") public String processData( McpSyncRequestContext context, @McpToolParam(description = "Data to process", required = true) String data) { // Send logging notification context.info("Processing data: " + data); // Send progress notification (using convenient method) context.progress(p -> p.progress(0.5).total(1.0).message("Processing...")); // Ping the client context.ping(); return "Processed: " + data.toUpperCase(); } ---- ==== Dynamic Schema Support Tools can accept `CallToolRequest` for runtime schema handling: [source,java] ---- @McpTool(name = "flexible-tool", description = "Process dynamic schema") public CallToolResult processDynamic(CallToolRequest request) { Map args = request.arguments(); // Process based on runtime schema String result = "Processed " + args.size() + " arguments dynamically"; return CallToolResult.builder() .addTextContent(result) .build(); } ---- ==== Progress Tracking Tools can receive progress tokens for tracking long-running operations: [source,java] ---- @McpTool(name = "long-task", description = "Long-running task with progress") public String performLongTask( McpSyncRequestContext context, @McpToolParam(description = "Task name", required = true) String taskName) { // Access progress token from context String progressToken = context.request().progressToken(); if (progressToken != null) { context.progress(p -> p.progress(0.0).total(1.0).message("Starting task")); // Perform work... context.progress(p -> p.progress(1.0).total(1.0).message("Task completed")); } return "Task " + taskName + " completed"; } ---- === @McpResource The `@McpResource` annotation provides access to resources via URI templates. ==== Annotation Attributes [cols="1,1,3"] |=== |Attribute |Default |Description |`uri` |`""` |The URI (or URI template) of the resource. Use `+{varName}+` for template variables. |`name` |`""` |Programmatic identifier. Also used as display name when `title` is absent. |`title` |`""` |Optional human-readable name for display purposes. |`description` |`""` |Description of what the resource represents. |`mimeType` |`"text/plain"` |The MIME type of the resource content. |`metaProvider` |`DefaultMetaProvider.class` |Class implementing `MetaProvider` that supplies data for the `_meta` field. |`annotations` |`@McpAnnotations(...)` |Client annotations for audience, priority, and last-modified metadata. |=== The nested `McpAnnotations` for resources supports: [cols="1,1,3"] |=== |Attribute |Default |Description |`audience` |`{Role.USER}` |Describes intended consumers (`Role.USER`, `Role.ASSISTANT`, or both). |`priority` |`0.5` |Importance from `0.0` (least) to `1.0` (most). A value of `1.0` indicates effectively required. |`lastModified` |`""` |ISO 8601 date-time when the resource was last modified. |=== ==== Basic Usage [source,java] ---- @Component public class ResourceProvider { @McpResource( uri = "config://{key}", name = "Configuration", title = "App Configuration", description = "Provides configuration data") public String getConfig(String key) { return configData.get(key); } } ---- ==== With ReadResourceResult [source,java] ---- @McpResource( uri = "user-profile://{username}", name = "User Profile", description = "Provides user profile information") public ReadResourceResult getUserProfile(String username) { String profileData = loadUserProfile(username); return new ReadResourceResult(List.of( new TextResourceContents( "user-profile://" + username, "application/json", profileData) )); } ---- ==== With Request Context [source,java] ---- @McpResource( uri = "data://{id}", name = "Data Resource", description = "Resource with request context") public ReadResourceResult getData( McpSyncRequestContext context, String id) { // Send logging notification using convenient method context.info("Accessing resource: " + id); // Ping the client context.ping(); String data = fetchData(id); return new ReadResourceResult(List.of( new TextResourceContents("data://" + id, "text/plain", data) )); } ---- === @McpPrompt The `@McpPrompt` annotation generates prompt messages for AI interactions. ==== Annotation Attributes [cols="1,1,3"] |=== |Attribute |Default |Description |`name` |`""` |Unique identifier for the prompt. |`title` |`""` |Optional human-readable name for display purposes. |`description` |`""` |Optional human-readable description. |`metaProvider` |`DefaultMetaProvider.class` |Class implementing `MetaProvider` that supplies data for the `_meta` field. |=== ==== Basic Usage [source,java] ---- @Component public class PromptProvider { @McpPrompt( name = "greeting", description = "Generate a greeting message") public GetPromptResult greeting( @McpArg(name = "name", description = "User's name", required = true) String name) { String message = "Hello, " + name + "! How can I help you today?"; return new GetPromptResult( "Greeting", List.of(new PromptMessage(Role.ASSISTANT, new TextContent(message))) ); } } ---- ==== With Optional Arguments [source,java] ---- @McpPrompt( name = "personalized-message", description = "Generate a personalized message") public GetPromptResult personalizedMessage( @McpArg(name = "name", required = true) String name, @McpArg(name = "age", required = false) Integer age, @McpArg(name = "interests", required = false) String interests) { StringBuilder message = new StringBuilder(); message.append("Hello, ").append(name).append("!\n\n"); if (age != null) { message.append("At ").append(age).append(" years old, "); // Add age-specific content } if (interests != null && !interests.isEmpty()) { message.append("Your interest in ").append(interests); // Add interest-specific content } return new GetPromptResult( "Personalized Message", List.of(new PromptMessage(Role.ASSISTANT, new TextContent(message.toString()))) ); } ---- === @McpComplete The `@McpComplete` annotation provides auto-completion functionality for prompts and resource URI templates. Use either the `prompt` or `uri` attribute — not both simultaneously: * `prompt` — completes an argument of the named prompt * `uri` — completes a URI template expression of the named resource URI ==== Prompt Argument Completion [source,java] ---- @Component public class CompletionProvider { @McpComplete(prompt = "city-search") public List completeCityName(String prefix) { return cities.stream() .filter(city -> city.toLowerCase().startsWith(prefix.toLowerCase())) .limit(10) .toList(); } } ---- ==== Resource URI Completion [source,java] ---- @McpComplete(uri = "config://{key}") public List completeConfigKey(String prefix) { return configKeys.stream() .filter(key -> key.startsWith(prefix)) .limit(10) .toList(); } ---- ==== With CompleteRequest.CompleteArgument [source,java] ---- @McpComplete(prompt = "travel-planner") public List completeTravelDestination(CompleteRequest.CompleteArgument argument) { String prefix = argument.value().toLowerCase(); String argumentName = argument.name(); // Different completions based on argument name if ("city".equals(argumentName)) { return completeCities(prefix); } else if ("country".equals(argumentName)) { return completeCountries(prefix); } return List.of(); } ---- ==== With CompleteResult [source,java] ---- @McpComplete(prompt = "code-completion") public CompleteResult completeCode(String prefix) { List completions = generateCodeCompletions(prefix); return new CompleteResult( new CompleteResult.CompleteCompletion( completions, completions.size(), // total hasMoreCompletions // hasMore flag ) ); } ---- == Stateless vs Stateful Implementations === Unified Request Context (Recommended) Use `McpSyncRequestContext` or `McpAsyncRequestContext` for a unified interface that works with both stateful and stateless operations: [source,java] ---- public record UserInfo(String name, String email, int age) {} @McpTool(name = "unified-tool", description = "Tool with unified request context") public String unifiedTool( McpSyncRequestContext context, @McpToolParam(description = "Input", required = true) String input) { // Access request and metadata String progressToken = context.request().progressToken(); // Logging with convenient methods context.info("Processing: " + input); // Progress notifications (Note client should set a progress token // with its request to be able to receive progress updates) context.progress(50); // Simple percentage // Ping client context.ping(); // Check capabilities before using if (context.elicitEnabled()) { // Request user input (only in stateful mode) StructuredElicitResult elicitResult = context.elicit(UserInfo.class); if (elicitResult.action() == ElicitResult.Action.ACCEPT) { // Use elicited data } } if (context.sampleEnabled()) { // Request LLM sampling (only in stateful mode) CreateMessageResult samplingResult = context.sample("Generate response"); // Use sampling result } // Access root directories (only in stateful mode) if (context.rootsEnabled()) { ListRootsResult roots = context.roots(); roots.roots().forEach(root -> context.info("Root: " + root.uri())); } return "Processed with unified context"; } ---- === Simple Operations (No Context) For simple operations, you can omit context parameters entirely: [source,java] ---- @McpTool(name = "simple-add", description = "Simple addition") public int simpleAdd( @McpToolParam(description = "First number", required = true) int a, @McpToolParam(description = "Second number", required = true) int b) { return a + b; } ---- === Lightweight Stateless (with McpTransportContext) For stateless operations where you need minimal transport context: [source,java] ---- @McpTool(name = "stateless-tool", description = "Stateless with transport context") public String statelessTool( McpTransportContext context, @McpToolParam(description = "Input", required = true) String input) { // Access transport-level context only // No bidirectional operations (roots, elicitation, sampling) return "Processed: " + input; } ---- [IMPORTANT] **Stateless servers do not support bidirectional operations:** Therefore methods using `McpSyncRequestContext` or `McpAsyncRequestContext` in stateless mode are ignored. == Method Filtering by Server Type The MCP annotations framework automatically filters annotated methods based on the server type and method characteristics. This ensures that only appropriate methods are registered for each server configuration. A warning is logged for each filtered method to help with debugging. === Synchronous vs Asynchronous Filtering ==== Synchronous Servers Synchronous servers (configured with `spring.ai.mcp.server.type=SYNC`) use synchronous providers that: * **Accept** methods with non-reactive return types: - Primitive types (`int`, `double`, `boolean`) - Object types (`String`, `Integer`, custom POJOs) - MCP types (`CallToolResult`, `ReadResourceResult`, `GetPromptResult`, `CompleteResult`) - Collections (`List`, `Map`) * **Filter out** methods with reactive return types: - `Mono` - `Flux` - `Publisher` [source,java] ---- @Component public class SyncTools { @McpTool(name = "sync-tool", description = "Synchronous tool") public String syncTool(String input) { // This method WILL be registered on sync servers return "Processed: " + input; } @McpTool(name = "async-tool", description = "Async tool") public Mono asyncTool(String input) { // This method will be FILTERED OUT on sync servers // A warning will be logged return Mono.just("Processed: " + input); } } ---- ==== Asynchronous Servers Asynchronous servers (configured with `spring.ai.mcp.server.type=ASYNC`) use asynchronous providers that: * **Accept** methods with reactive return types: - `Mono` (for single results) - `Flux` (for streaming results) - `Publisher` (generic reactive type) * **Filter out** methods with non-reactive return types: - Primitive types - Object types - Collections - MCP result types [source,java] ---- @Component public class AsyncTools { @McpTool(name = "async-tool", description = "Async tool") public Mono asyncTool(String input) { // This method WILL be registered on async servers return Mono.just("Processed: " + input); } @McpTool(name = "sync-tool", description = "Sync tool") public String syncTool(String input) { // This method will be FILTERED OUT on async servers // A warning will be logged return "Processed: " + input; } } ---- === Stateful vs Stateless Filtering ==== Stateful Servers Stateful servers support bidirectional communication and accept methods with: * **Bidirectional context parameters**: - `McpSyncRequestContext` (for sync operations) - `McpAsyncRequestContext` (for async operations) - `McpSyncServerExchange` (legacy, for sync operations) - `McpAsyncServerExchange` (legacy, for async operations) * Support for bidirectional operations: - `roots()` - Access root directories - `elicit()` - Request user input - `sample()` - Request LLM sampling [source,java] ---- @Component public class StatefulTools { @McpTool(name = "interactive-tool", description = "Tool with bidirectional operations") public String interactiveTool( McpSyncRequestContext context, @McpToolParam(description = "Input", required = true) String input) { // This method WILL be registered on stateful servers // Can use elicitation, sampling, roots if (context.sampleEnabled()) { var samplingResult = context.sample("Generate response"); // Process sampling result... } return "Processed with context"; } } ---- ==== Stateless Servers Stateless servers are optimized for simple request-response patterns and: * **Filter out** methods with bidirectional context parameters: - Methods with `McpSyncRequestContext` are skipped - Methods with `McpAsyncRequestContext` are skipped - Methods with `McpSyncServerExchange` are skipped - Methods with `McpAsyncServerExchange` are skipped - A warning is logged for each filtered method * **Accept** methods with: - `McpTransportContext` (lightweight stateless context) - No context parameter at all - Only regular `@McpToolParam` parameters * Do **not** support bidirectional operations: - `roots()` - Not available - `elicit()` - Not available - `sample()` - Not available [source,java] ---- @Component public class StatelessTools { @McpTool(name = "simple-tool", description = "Simple stateless tool") public String simpleTool(@McpToolParam(description = "Input") String input) { // This method WILL be registered on stateless servers return "Processed: " + input;

return new ReadResourceResult(List.of( new TextResourceContents("async-data://" + id, "text/plain", data) )); }).delayElements(Duration.ofMillis(100)); } } ---- == Spring Boot Integration With Spring Boot auto-configuration, annotated beans are automatically detected and registered: [source,java] ---- @SpringBootApplication public class McpServerApplication { public static void main(String[] args) { SpringApplication.run(McpServerApplication.class, args); } } @Component public class MyMcpTools { // Your @McpTool annotated methods } @Component public class MyMcpResources { // Your @McpResource annotated methods } ---- The auto-configuration will: 1. Scan for beans with MCP annotations 2. Create appropriate specifications 3. Register them with the MCP server 4. Handle both sync and async implementations based on configuration == Configuration Properties Configure the server annotation scanner: [source,yaml] ---- spring: ai: mcp: server: type: SYNC # or ASYNC annotation-scanner: enabled: true ---- == Additional Resources * xref:api/mcp/mcp-annotations-overview.adoc[MCP Annotations Overview] * xref:api/mcp/mcp-annotations-client.adoc[Client Annotations] * xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters] * xref:api/mcp/mcp-server-boot-starter-docs.adoc[MCP Server Boot Starter] ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/mcp/mcp-annotations-special-params.adoc ================================================ = MCP Annotations Special Parameters The MCP Annotations support several special parameter types that provide additional context and functionality to annotated methods. These parameters are automatically injected by the framework and are excluded from JSON schema generation. == Special Parameter Types === MetaProvider The `MetaProvider` interface supplies data for the `_meta` field in tool, prompt, and resource declarations. ==== Overview * Implemented as a class referenced in `@McpTool(metaProvider = ...)`, `@McpPrompt(metaProvider = ...)`, or `@McpResource(metaProvider = ...)` * Allows attaching static or computed metadata to a tool/prompt/resource specification at startup * The default `DefaultMetaProvider` returns an empty map (no `_meta` appended) ==== Custom MetaProvider [source,java] ---- public class MyToolMetaProvider implements MetaProvider { @Override public Map getMeta() { return Map.of( "version", "1.0", "team", "platform", "experimental", false ); } } @McpTool(name = "my-tool", description = "Tool with metadata", metaProvider = MyToolMetaProvider.class) public String myTool(@McpToolParam(description = "Input") String input) { return "Processed: " + input; } ---- The same pattern applies to `@McpPrompt` and `@McpResource`. === McpMeta The `McpMeta` class provides access to metadata from MCP requests, notifications, and results. ==== Overview * Automatically injected when used as a method parameter * Excluded from parameter count limits and JSON schema generation * Provides convenient access to metadata through the `get(String key)` method * If no metadata is present in the request, an empty `McpMeta` object is injected ==== Usage in Tools [source,java] ---- @McpTool(name = "contextual-tool", description = "Tool with metadata access") public String processWithContext( @McpToolParam(description = "Input data", required = true) String data, McpMeta meta) { // Access metadata from the request String userId = (String) meta.get("userId"); String sessionId = (String) meta.get("sessionId"); String userRole = (String) meta.get("userRole"); // Use metadata to customize behavior if ("admin".equals(userRole)) { return processAsAdmin(data, userId); } else { return processAsUser(data, userId); } } ---- ==== Usage in Resources [source,java] ---- @McpResource(uri = "secure-data://{id}", name = "Secure Data") public ReadResourceResult getSecureData(String id, McpMeta meta) { String requestingUser = (String) meta.get("requestingUser");

} ---- === @McpProgressToken The `@McpProgressToken` annotation marks a parameter to receive progress tokens from MCP requests. ==== Overview * Parameter type should be `String` * Automatically receives the progress token value from the request * Excluded from the generated JSON schema * If no progress token is present, `null` is injected * Used for tracking long-running operations ==== Usage in Tools [source,java] ---- @McpTool(name = "long-operation", description = "Long-running operation with progress") public String performLongOperation( @McpProgressToken String progressToken, @McpToolParam(description = "Operation name", required = true) String operation, @McpToolParam(description = "Duration in seconds", required = true) int duration, McpSyncServerExchange exchange) { if (progressToken != null) { // Send initial progress exchange.progressNotification(new ProgressNotification( progressToken, 0.0, 1.0, "Starting " + operation)); // Simulate work with progress updates for (int i = 1; i <= duration; i++) { Thread.sleep(1000); double progress = (double) i / duration; exchange.progressNotification(new ProgressNotification( progressToken, progress, 1.0, String.format("Processing... %d%%", (int)(progress * 100)))); } } return "Operation " + operation + " completed"; } ---- ==== Usage in Resources [source,java] ---- @McpResource(uri = "large-file://{path}", name = "Large File Resource") public ReadResourceResult getLargeFile( @McpProgressToken String progressToken, String path, McpSyncServerExchange exchange) { File file = new File(path);

if (progressToken != null) { exchange.progressNotification(new ProgressNotification( progressToken, fileSize, fileSize, "File read complete")); } return new ReadResourceResult(List.of( new TextResourceContents("large-file://" + path, "text/plain", content) )); } ---- === McpSyncRequestContext / McpAsyncRequestContext Request context objects provide unified access to MCP request information and server-side operations. ==== Overview * Provides unified interface for both stateful and stateless operations * Automatically injected when used as a parameter * Excluded from JSON schema generation * Enables advanced features like logging, progress notifications, sampling, elicitation, and roots access * Works with both stateful (server exchange) and stateless (transport context) modes ==== Context Getters Both `McpSyncRequestContext` and `McpAsyncRequestContext` expose the following read-only context: [cols="1,3"] |=== |Method |Description |`request()` |The original MCP request (e.g., `CallToolRequest`, `ReadResourceRequest`). Use `request().progressToken()` to access the progress token. |`exchange()` |The underlying server exchange (`McpSyncServerExchange` / `McpAsyncServerExchange`). Available in stateful mode only; `null` in stateless mode. |`sessionId()` |The current session identifier. |`clientInfo()` |The client implementation info (`Implementation`). |`clientCapabilities()` |The capabilities declared by the client. |`requestMeta()` |Metadata map from the `_meta` field of the request. Prefer this over injecting `McpMeta` when already using a context object. |`transportContext()` |The transport-level context (`McpTransportContext`). |=== ==== McpSyncRequestContext Features [source,java] ---- public record UserInfo(String name, String email, int age) {} @McpTool(name = "advanced-tool", description = "Tool with full server capabilities") public String advancedTool( McpSyncRequestContext context, @McpToolParam(description = "Input", required = true) String input) { // Send logging notification context.info("Processing: " + input);

} // Access client root directories (only available in stateful mode) if (context.rootsEnabled()) { ListRootsResult roots = context.roots(); roots.roots().forEach(root -> context.info("Client root: " + root.uri())); } return "Processed with advanced features"; } ---- ==== McpAsyncRequestContext Features [source,java] ---- public record UserInfo(String name, String email, int age) {} @McpTool(name = "async-advanced-tool", description = "Async tool with server capabilities") public Mono asyncAdvancedTool( McpAsyncRequestContext context, @McpToolParam(description = "Input", required = true) String input) { return context.info("Async processing: " + input) .then(context.progress(25)) .then(context.ping()) .flatMap(v -> { // Perform elicitation if supported if (context.elicitEnabled()) { return context.elicitation(UserInfo.class) .map(userInfo -> "Processing for user: " + userInfo.name()); } return Mono.just("Processing..."); }) .flatMap(msg -> { // Perform sampling if supported if (context.sampleEnabled()) { return context.sampling("Process: " + input) .map(result -> "Completed: " + result); } return Mono.just("Completed: " + msg); }); } ---- === McpTransportContext Lightweight context for stateless operations. ==== Overview * Provides minimal context without full server exchange * Used in stateless implementations * Automatically injected when used as a parameter * Excluded from JSON schema generation ==== Usage Example [source,java] ---- @McpTool(name = "stateless-tool", description = "Stateless tool with context") public String statelessTool( McpTransportContext context, @McpToolParam(description = "Input", required = true) String input) { // Limited context access // Useful for transport-level operations return "Processed in stateless mode: " + input; } @McpResource(uri = "stateless://{id}", name = "Stateless Resource") public ReadResourceResult statelessResource( McpTransportContext context, String id) { // Access transport context if needed String data = loadData(id); return new ReadResourceResult(List.of( new TextResourceContents("stateless://" + id, "text/plain", data) )); } ---- === CallToolRequest Special parameter for tools that need access to the full request with dynamic schema. ==== Overview * Provides access to the complete tool request * Enables dynamic schema handling at runtime * Automatically injected and excluded from schema generation * Useful for flexible tools that adapt to different input schemas ==== Usage Examples [source,java] ---- @McpTool(name = "dynamic-tool", description = "Tool with dynamic schema support") public CallToolResult processDynamicSchema(CallToolRequest request) { Map args = request.arguments(); // Process based on whatever schema was provided at runtime StringBuilder result = new StringBuilder("Processed:\n"); for (Map.Entry entry : args.entrySet()) { result.append(" ").append(entry.getKey()) .append(": ").append(entry.getValue()).append("\n"); } return CallToolResult.builder() .addTextContent(result.toString()) .build(); } ---- ==== Mixed Parameters [source,java] ---- @McpTool(name = "hybrid-tool", description = "Tool with typed and dynamic parameters") public String processHybrid( @McpToolParam(description = "Operation", required = true) String operation, @McpToolParam(description = "Priority", required = false) Integer priority, CallToolRequest request) { // Use typed parameters for known fields String result = "Operation: " + operation; if (priority != null) { result += " (Priority: " + priority + ")"; } // Access additional dynamic arguments Map allArgs = request.arguments(); // Remove known parameters to get only additional ones Map additionalArgs = new HashMap<>(allArgs); additionalArgs.remove("operation"); additionalArgs.remove("priority"); if (!additionalArgs.isEmpty()) { result += " with " + additionalArgs.size() + " additional parameters"; } return result; } ---- ==== With Progress Token [source,java] ---- @McpTool(name = "flexible-with-progress", description = "Flexible tool with progress") public CallToolResult flexibleWithProgress( @McpProgressToken String progressToken, CallToolRequest request, McpSyncServerExchange exchange) { Map args = request.arguments(); if (progressToken != null) { exchange.progressNotification(new ProgressNotification( progressToken, 0.0, 1.0, "Processing dynamic request")); } // Process dynamic arguments String result = processDynamicArgs(args); if (progressToken != null) { exchange.progressNotification(new ProgressNotification( progressToken, 1.0, 1.0, "Complete")); } return CallToolResult.builder() .addTextContent(result) .build(); } ---- == Parameter Injection Rules === Automatic Injection The following parameters are automatically injected by the framework: 1. `McpMeta` - Metadata from the `_meta` field of the request 2. `@McpProgressToken String` - Progress token if available 3. `McpSyncRequestContext` / `McpAsyncRequestContext` - Unified request context (recommended) 4. `McpSyncServerExchange` / `McpAsyncServerExchange` - Low-level server exchange context (stateful only) 5. `McpTransportContext` - Transport context for stateless operations 6. `CallToolRequest` - Full tool request for dynamic schema (tools only) === Schema Generation Special parameters are excluded from JSON schema generation: * They don't appear in the tool's input schema * They don't count towards parameter limits * They're not visible to MCP clients === Null Handling * `McpMeta` - Never null, empty object if no metadata * `@McpProgressToken` - Can be null if no token provided * Server exchanges - Never null when properly configured * `CallToolRequest` - Never null for tool methods == Best Practices === Use McpMeta for Context [source,java] ---- @McpTool(name = "context-aware", description = "Context-aware tool") public String contextAware( @McpToolParam(description = "Data", required = true) String data, McpMeta meta) { // Always check for null values in metadata String userId = (String) meta.get("userId"); if (userId == null) { userId = "anonymous"; } return processForUser(data, userId); } ---- === Progress Token Null Checks [source,java] ---- @McpTool(name = "safe-progress", description = "Safe progress handling") public String safeProgress( @McpProgressToken String progressToken, @McpToolParam(description = "Task", required = true) String task, McpSyncServerExchange exchange) { // Always check if progress token is available if (progressToken != null) { exchange.progressNotification(new ProgressNotification( progressToken, 0.0, 1.0, "Starting")); } // Perform work... if (progressToken != null) { exchange.progressNotification(new ProgressNotification( progressToken, 1.0, 1.0, "Complete")); } return "Task completed"; } ---- === Choose the Right Context * Use `McpSyncRequestContext` / `McpAsyncRequestContext` for unified access to request context, supporting both stateful and stateless operations with convenient helper methods * Use `McpTransportContext` for simple stateless operations when you only need transport-level context * Omit context parameters entirely for the simplest cases === Capability Checking Always check capability support before using client features: [source,java] ---- @McpTool(name = "capability-aware", description = "Tool that checks capabilities") public String capabilityAware( McpSyncRequestContext context, @McpToolParam(description = "Data", required = true) String data) { // Check if elicitation is supported before using it if (context.elicitEnabled()) { // Safe to use elicitation var result = context.elicit(UserInfo.class); // Process result... } // Check if sampling is supported before using it if (context.sampleEnabled()) { // Safe to use sampling var samplingResult = context.sample("Process: " + data); // Process result... } // Note: Stateless servers do not support bidirectional operations // (roots, elicitation, sampling) and will return false for these checks return "Processed with capability awareness";

It supports both synchronous and asynchronous client implementations with various transport options. The MCP Client Boot Starter provides: * Management of multiple client instances * Automatic client initialization (if enabled) * Support for multiple named transports (STDIO, Http/SSE and Streamable HTTP) * Integration with Spring AI's tool execution framework * Tool filtering capabilities for selective tool inclusion/exclusion * Customizable tool name prefix generation for avoiding naming conflicts * Proper lifecycle management with automatic cleanup of resources when the application context is closed * Customizable client creation through customizers == Starters === Standard MCP Client [source,xml] ---- org.springframework.ai spring-ai-starter-mcp-client ---- The standard starter connects simultaneously to one or more MCP servers over `STDIO` (in-process), `SSE`, `Streamable-HTTP` and `Stateless Streamable-HTTP` transports. The SSE and Streamable-Http transports use the JDK HttpClient-based transport implementation. Each connection to an MCP server creates a new MCP client instance. You can choose either `SYNC` or `ASYNC` MCP clients (note: you cannot mix sync and async clients). For production deployment, we recommend using the WebFlux-based SSE & StreamableHttp connection with the `spring-ai-starter-mcp-client-webflux`. === WebFlux Client The WebFlux starter provides similar functionality to the standard starter but uses a WebFlux-based Streamable-Http, Stateless Streamable-Http and SSE transport implementation. [source,xml] ---- org.springframework.ai spring-ai-starter-mcp-client-webflux ---- == Configuration Properties === Common Properties The common properties are prefixed with `spring.ai.mcp.client`: [cols="3,4,3"] |=== |Property |Description |Default Value |`enabled` |Enable/disable the MCP client |`true` |`name` |Name of the MCP client instance |`spring-ai-mcp-client` |`version` |Version of the MCP client instance |`1.0.0` |`initialized` |Whether to initialize clients on creation |`true` |`request-timeout` |Timeout duration for MCP client requests |`20s` |`type` |Client type (SYNC or ASYNC). All clients must be either sync or async; mixing is not supported |`SYNC` |`root-change-notification` |Enable/disable root change notifications for all clients |`true` |`toolcallback.enabled` |Enable/disable the MCP tool callback integration with Spring AI's tool execution framework |`true` |=== === MCP Annotations Properties MCP Client Annotations provide a declarative way to implement MCP client handlers using Java annotations. The client mcp-annotations properties are prefixed with `spring.ai.mcp.client.annotation-scanner`: [cols="3,4,3"] |=== |Property |Description |Default Value |`enabled` |Enable/disable the MCP client annotations auto-scanning |`true` |=== === Stdio Transport Properties Properties for Standard I/O transport are prefixed with `spring.ai.mcp.client.stdio`: [cols="3,4,3"] |=== |Property |Description |Default Value |`servers-configuration` |Resource containing the MCP servers configuration in JSON format |- |`connections` |Map of named stdio connection configurations |- |`connections.[name].command` |The command to execute for the MCP server |- |`connections.[name].args` |List of command arguments |- |`connections.[name].env` |Map of environment variables for the server process |- |=== Example configuration: [source,yaml] ---- spring: ai: mcp: client: stdio: root-change-notification: true connections: server1: command: /path/to/server args: - --port=8080 - --mode=production env: API_KEY: your-api-key DEBUG: "true" ---- Alternatively, you can configure stdio connections using an external JSON file using the link:https://modelcontextprotocol.io/quickstart/user[Claude Desktop format]: [source,yaml] ---- spring: ai: mcp: client: stdio: servers-configuration: classpath:mcp-servers.json ---- The Claude Desktop format looks like this: [source,json] ---- { "mcpServers": { "filesystem": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-filesystem", "/Users/username/Desktop", "/Users/username/Downloads" ] } } } ---- === Windows STDIO Configuration IMPORTANT: 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. ==== Why Windows Needs Special Handling When Java's `ProcessBuilder` (used internally by `StdioClientTransport`) attempts to spawn a process on Windows, it can only execute: * Native executables (`.exe` files) * System commands available to `cmd.exe` Windows batch files like `npx.cmd`, `npm.cmd`, and even `python.cmd` (from the Microsoft Store) require the `cmd.exe` shell to execute them. ==== Solution: cmd.exe Wrapper Wrap batch file commands with `cmd.exe /c`: **Windows Configuration:** [source,json] ---- { "mcpServers": { "filesystem": { "command": "cmd.exe", "args": [ "/c", "npx", "-y", "@modelcontextprotocol/server-filesystem", "C:\\Users\\username\\Desktop" ] } } } ---- **Linux/macOS Configuration:** [source,json] ---- { "mcpServers": { "filesystem": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-filesystem", "/Users/username/Desktop" ] } } } ---- ==== Cross-Platform Programmatic Configuration For applications that need to work across platforms without separate configuration files, use OS detection in your Spring Boot application: [source,java] ---- @Bean(destroyMethod = "close") @ConditionalOnMissingBean(McpSyncClient.class) public McpSyncClient mcpClient() { ServerParameters stdioParams; if (isWindows()) { // Windows: cmd.exe /c npx approach var winArgs = new ArrayList<>(Arrays.asList( "/c", "npx", "-y", "@modelcontextprotocol/server-filesystem", "target")); stdioParams = ServerParameters.builder("cmd.exe") .args(winArgs) .build(); } else { // Linux/Mac: direct npx approach stdioParams = ServerParameters.builder("npx") .args("-y", "@modelcontextprotocol/server-filesystem", "target") .build(); } return McpClient.sync(new StdioClientTransport(stdioParams, McpJsonDefaults.getMapper())) .requestTimeout(Duration.ofSeconds(10)) .build() .initialize(); } private static boolean isWindows() { return System.getProperty("os.name").toLowerCase().contains("win"); } ---- NOTE: When using programmatic configuration with `@Bean`, add `@ConditionalOnMissingBean(McpSyncClient.class)` to avoid conflicts with auto-configuration from JSON files. ==== Path Considerations **Relative paths** (recommended for portability): [source,json] ---- { "command": "cmd.exe", "args": ["/c", "npx", "-y", "@modelcontextprotocol/server-filesystem", "target"] } ---- The MCP server resolves relative paths based on the application's working directory. **Absolute paths** (Windows requires backslashes or escaped forward slashes): [source,json] ---- { "command": "cmd.exe", "args": ["/c", "npx", "-y", "@modelcontextprotocol/server-filesystem", "C:\\Users\\username\\project\\target"] } ---- ==== Common Windows Batch Files Requiring cmd.exe * `npx.cmd`, `npm.cmd` - Node package managers * `python.cmd` - Python (Microsoft Store installation) * `pip.cmd` - Python package manager * `mvn.cmd` - Maven wrapper * `gradle.cmd` - Gradle wrapper * Custom `.cmd` or `.bat` scripts ==== Reference Implementation See 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. === Streamable-HTTP Transport Properties Used for connecting to Streamable-HTTP and Stateless Streamable-HTTP MCP servers. Properties for Streamable-HTTP transport are prefixed with `spring.ai.mcp.client.streamable-http`: [cols="3,4,3"] |=== |Property |Description | Default Value |`connections` |Map of named Streamable-HTTP connection configurations |- |`connections.[name].url` |Base URL endpoint for Streamable-Http communication with the MCP server |- |`connections.[name].endpoint` |the streamable-http endpoint (as url suffix) to use for the connection |`/mcp` |=== Example configuration: [source,yaml] ---- spring: ai: mcp: client: streamable-http: connections: server1: url: http://localhost:8080 server2: url: http://otherserver:8081 endpoint: /custom-sse ---- === SSE Transport Properties Properties for Server-Sent Events (SSE) transport are prefixed with `spring.ai.mcp.client.sse`: [cols="3,4,3"] |=== |Property |Description | Default Value |`connections` |Map of named SSE connection configurations |- |`connections.[name].url` |Base URL endpoint for SSE communication with the MCP server |- |`connections.[name].sse-endpoint` |the sse endpoint (as url suffix) to use for the connection |`/sse` |=== Example configurations: [source,yaml] ---- spring: ai: mcp: client: sse: connections: # Simple configuration using default /sse endpoint server1: url: http://localhost:8080 # Custom SSE endpoint server2: url: http://otherserver:8081 sse-endpoint: /custom-sse # Complex URL with path and token (like MCP Hub) mcp-hub: url: http://localhost:3000 sse-endpoint: /mcp-hub/sse/cf9ec4527e3c4a2cbb149a85ea45ab01 # SSE endpoint with query parameters api-server: url: https://api.example.com sse-endpoint: /v1/mcp/events?token=abc123&format=json ---- ==== URL Splitting Guidelines When you have a full SSE URL, split it into base URL and endpoint path: [cols="2,2"] |=== |Full URL |Configuration |`\http://localhost:3000/mcp-hub/sse/token123` |`url: http://localhost:3000` + `sse-endpoint: /mcp-hub/sse/token123` |`\https://api.service.com/v2/events?key=secret` |`url: https://api.service.com` + `sse-endpoint: /v2/events?key=secret` |`\http://localhost:8080/sse` |`url: http://localhost:8080` + `sse-endpoint: /sse` (or omit for default) |=== ==== Troubleshooting SSE Connections *404 Not Found Errors:* * Verify URL splitting: ensure the base `url` contains only the scheme, host, and port * Check the `sse-endpoint` starts with `/` and includes the full path and query parameters * Test the full URL directly in a browser or curl to confirm it's accessible === Streamable Http Transport Properties Properties for Streamable Http transport are prefixed with `spring.ai.mcp.client.streamable-http`: [cols="3,4,3"] |=== |Property |Description | Default Value |`connections` |Map of named Streamable Http connection configurations |- |`connections.[name].url` |Base URL endpoint for Streamable-Http communication with the MCP server |- |`connections.[name].endpoint` |the streamable-http endpoint (as url suffix) to use for the connection |`/mcp` |=== Example configuration: [source,yaml] ---- spring: ai: mcp: client: streamable-http: connections: server1: url: http://localhost:8080 server2: url: http://otherserver:8081 endpoint: /custom-sse ---- == Features === Sync/Async Client Types The starter supports two types of clients: * Synchronous - default client type (`spring.ai.mcp.client.type=SYNC`), suitable for traditional request-response patterns with blocking operations **NOTE:** The SYNC client will register only synchronous MCP annotated methods. Asynchronous methods will be ignored. * Asynchronous - suitable for reactive applications with non-blocking operations, configured using `spring.ai.mcp.client.type=ASYNC` **NOTE:** The ASYNC client will register only asynchronous MCP annotated methods. Synchronous methods will be ignored. === Client Customization The 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. ==== Customization Types The following customization options are available: * *Request Configuration* - Set custom request timeouts * 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. * link:https://modelcontextprotocol.io/specification/2025-06-18/client/roots[*File system (Roots) Access*] - standardized way for clients to expose filesystem `roots` to servers. Roots define the boundaries of where servers can operate within the filesystem, allowing them to understand which directories and files they have access to. Servers can request the list of roots from supporting clients and receive notifications when that list changes. * 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. * *Event Handlers* - client's handler to be notified when a certain server event occurs: - Tools change notifications - when the list of available server tools changes - Resources change notifications - when the list of available server resources changes. - Prompts change notifications - when the list of available server prompts changes. - link:https://modelcontextprotocol.io/specification/2025-06-18/server/utilities/logging[*Logging Handlers*] - standardized way for servers to send structured log messages to clients. - link:https://modelcontextprotocol.io/specification/2025-06-18/basic/utilities/progress[*Progress Handlers*] - standardized way for servers to send structured progress messages to clients. Clients can control logging verbosity by setting minimum log levels ==== Client Customization Example You can implement `McpCustomizer` for synchronous clients or `McpCustomizer` for asynchronous clients, depending on your application's needs. [tabs] ====== Sync:: + [source,java] ---- @Component public class CustomMcpSyncClientCustomizer implements McpCustomizer { @Override public void customize(String serverConfigurationName, McpClient.SyncSpec spec) { // Customize the request timeout configuration spec.requestTimeout(Duration.ofSeconds(30)); // Sets the root URIs that this client can access. spec.roots(roots); // Sets a custom sampling handler for processing message creation requests. spec.sampling((CreateMessageRequest messageRequest) -> { // Handle sampling CreateMessageResult result = ... return result; }); // Sets a custom elicitation handler for processing elicitation requests. spec.elicitation((ElicitRequest request) -> { // handle elicitation return new ElicitResult(ElicitResult.Action.ACCEPT, Map.of("message", request.message())); }); // Adds a consumer to be notified when progress notifications are received. spec.progressConsumer((ProgressNotification progress) -> { // Handle progress notifications }); // Adds a consumer to be notified when the available tools change, such as tools // being added or removed. spec.toolsChangeConsumer((List tools) -> { // Handle tools change }); // Adds a consumer to be notified when the available resources change, such as resources // being added or removed. spec.resourcesChangeConsumer((List resources) -> { // Handle resources change }); // Adds a consumer to be notified when the available prompts change, such as prompts // being added or removed. spec.promptsChangeConsumer((List prompts) -> { // Handle prompts change }); // Adds a consumer to be notified when logging messages are received from the server. spec.loggingConsumer((McpSchema.LoggingMessageNotification log) -> { // Handle log messages }); } } ---- Async:: + [source,java] ---- @Component public class CustomMcpAsyncClientCustomizer implements McpCustomizer { @Override public void customize(String serverConfigurationName, McpClient.AsyncSpec spec) { // Customize the async client configuration spec.requestTimeout(Duration.ofSeconds(30)); } } ---- ====== The `serverConfigurationName` parameter is the name of the server configuration that the customizer is being applied to and the MCP Client is created for. The MCP client auto-configuration automatically detects and applies any customizers found in the application context. === Transport Support The auto-configuration supports multiple transport types: * Standard I/O (Stdio) (activated by the `spring-ai-starter-mcp-client` and `spring-ai-starter-mcp-client-webflux`) * (HttpClient) HTTP/SSE and Streamable-HTTP (activated by the `spring-ai-starter-mcp-client`) * (WebFlux) HTTP/SSE and Streamable-HTTP (activated by the `spring-ai-starter-mcp-client-webflux`) === Tool Filtering The 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. To implement tool filtering, create a bean that implements the `McpToolFilter` interface: [source,java] ---- @Component public class CustomMcpToolFilter implements McpToolFilter { @Override public boolean test(McpConnectionInfo connectionInfo, McpSchema.Tool tool) { // Filter logic based on connection information and tool properties // Return true to include the tool, false to exclude it // Example: Exclude tools from a specific client if (connectionInfo.clientInfo().name().equals("restricted-client")) { return false; } // Example: Only include tools with specific names if (tool.name().startsWith("allowed_")) { return true; } // Example: Filter based on tool description or other properties if (tool.description() != null && tool.description().contains("experimental")) { return false; } return true; // Include all other tools by default } } ---- The `McpConnectionInfo` record provides access to: * `clientCapabilities` - The capabilities of the MCP client * `clientInfo` - Information about the MCP client (name and version) * `initializeResult` - The initialization result from the MCP server The filter is automatically detected and applied to both synchronous and asynchronous MCP tool callback providers. If no custom filter is provided, all discovered tools are included by default. Note: Only one `McpToolFilter` bean should be defined in the application context. If multiple filters are needed, combine them into a single composite filter implementation. === Tool Name Prefix Generation The 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. By 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: * Tracks all existing connections and tool names to ensure uniqueness * Formats tool names by replacing non-alphanumeric characters with underscores (e.g., `my-tool` becomes `my_tool`) * When duplicate tool names are detected across different connections, adds a counter prefix (e.g., `alt_1_toolName`, `alt_2_toolName`) * Is thread-safe and maintains idempotency - the same combination of (client, server, tool) always gets the same unique name * Ensures the final name doesn't exceed 64 characters (truncating from the beginning if necessary) For example: * First occurrence of tool `search` → `search` * Second occurrence of tool `search` from a different connection → `alt_1_search` * Tool with special characters `my-special-tool` → `my_special_tool` You can customize this behavior by providing your own implementation: [source,java] ---- @Component public class CustomToolNamePrefixGenerator implements McpToolNamePrefixGenerator { @Override public String prefixedToolName(McpConnectionInfo connectionInfo, Tool tool) { // Custom logic to generate prefixed tool names // Example: Use server name and version as prefix String serverName = connectionInfo.initializeResult().serverInfo().name(); String serverVersion = connectionInfo.initializeResult().serverInfo().version(); return serverName + "_v" + serverVersion.replace(".", "_") + "_" + tool.name(); } } ---- The `McpConnectionInfo` record provides comprehensive information about the MCP connection: * `clientCapabilities` - The capabilities of the MCP client * `clientInfo` - Information about the MCP client (name, title, and version) * `initializeResult` - The initialization result from the MCP server, including server information ==== Built-in Prefix Generators The framework provides several built-in prefix generators: * `DefaultMcpToolNamePrefixGenerator` - Ensures unique tool names by tracking duplicates and adding counter prefixes when needed (used by default if no custom bean is provided) * `McpToolNamePrefixGenerator.noPrefix()` - Returns tool names without any prefix (may cause conflicts if multiple servers provide tools with the same name) To disable prefixing entirely and use raw tool names (not recommended if using multiple MCP servers), register the no-prefix generator as a bean: [source,java] ---- @Configuration public class McpConfiguration { @Bean public McpToolNamePrefixGenerator mcpToolNamePrefixGenerator() { return McpToolNamePrefixGenerator.noPrefix(); } } ---- The prefix generator is automatically detected and applied to both synchronous and asynchronous MCP tool callback providers through Spring's `ObjectProvider` mechanism. If no custom generator bean is provided, the `DefaultMcpToolNamePrefixGenerator` is used automatically. WARNING: 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. === Tool Context to MCP Meta Converter The 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. This feature allows you to pass additional contextual information (e.g. user id, secrets token) as metadata along with the LLM's generated call arguments. For 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: [source,java] ---- ChatModel chatModel = ... String response = ChatClient.create(chatModel) .prompt("Tell me more about the customer with ID 42") .toolContext(Map.of("progressToken", "my-progress-token")) .call() .content(); ---- By default, if no custom converter bean is provided, the starter uses `ToolContextToMcpMetaConverter.defaultConverter()` which: * Filters out the MCP exchange key (`McpToolUtils.TOOL_CONTEXT_MCP_EXCHANGE_KEY`) * Filters out entries with null values * Passes through all other context entries as metadata You can customize this behavior by providing your own implementation: [source,java] ---- @Component public class CustomToolContextToMcpMetaConverter implements ToolContextToMcpMetaConverter { @Override public Map convert(ToolContext toolContext) { if (toolContext == null || toolContext.getContext() == null) { return Map.of(); } // Custom logic to convert tool context to MCP metadata Map metadata = new HashMap<>(); // Example: Add custom prefix to all keys for (Map.Entry entry : toolContext.getContext().entrySet()) { if (entry.getValue() != null) { metadata.put("app_" + entry.getKey(), entry.getValue()); } } // Example: Add additional metadata metadata.put("timestamp", System.currentTimeMillis()); metadata.put("source", "spring-ai"); return metadata; } } ---- ==== Built-in Converters The framework provides built-in converters: * `ToolContextToMcpMetaConverter.defaultConverter()` - Filters out MCP exchange key and null values (used by default if no custom bean is provided) * `ToolContextToMcpMetaConverter.noOp()` - Returns an empty map, effectively disabling context-to-metadata conversion To disable context-to-metadata conversion entirely: [source,java] ---- @Configuration public class McpConfiguration { @Bean public ToolContextToMcpMetaConverter toolContextToMcpMetaConverter() { return ToolContextToMcpMetaConverter.noOp(); } } ---- The converter is automatically detected and applied to both synchronous and asynchronous MCP tool callbacks through Spring's `ObjectProvider` mechanism. If no custom converter bean is provided, the default converter is used automatically. === Disable the MCP ToolCallback Auto-Configuration The MCP ToolCallback auto-configuration is enabled by default, but can be disabled with the `spring.ai.mcp.client.toolcallback.enabled=false` property. When disabled, no `ToolCallbackProvider` bean is created from the available MCP tools. == MCP Client Annotations The MCP Client Boot Starter automatically detects and registers annotated methods for handling various MCP client operations: * *@McpLogging* - Handles logging message notifications from MCP servers * *@McpSampling* - Handles sampling requests from MCP servers for LLM completions * *@McpElicitation* - Handles elicitation requests to gather additional information from users * *@McpProgress* - Handles progress notifications for long-running operations * *@McpToolListChanged* - Handles notifications when the server's tool list changes * *@McpResourceListChanged* - Handles notifications when the server's resource list changes * *@McpPromptListChanged* - Handles notifications when the server's prompt list changes Example usage: [source,java] ---- @Component public class McpClientHandlers { @McpLogging(clients = "server1") public void handleLoggingMessage(LoggingMessageNotification notification) { System.out.println("Received log: " + notification.level() + " - " + notification.data()); } @McpSampling(clients = "server1") public CreateMessageResult handleSamplingRequest(CreateMessageRequest request) { // Process the request and generate a response String response = generateLLMResponse(request); return CreateMessageResult.builder() .role(Role.ASSISTANT) .content(new TextContent(response)) .model("gpt-4") .build(); } @McpProgress(clients = "server1") public void handleProgressNotification(ProgressNotification notification) { double percentage = notification.progress() * 100; System.out.println(String.format("Progress: %.2f%% - %s", percentage, notification.message())); } @McpToolListChanged(clients = "server1") public void handleToolListChanged(List updatedTools) { System.out.println("Tool list updated: " + updatedTools.size() + " tools available"); // Update local tool registry toolRegistry.updateTools(updatedTools); } } ---- The annotations support both synchronous and asynchronous implementations, and can be configured for specific clients using the `clients` parameter: [source,java] ---- @McpLogging(clients = "server1") public void handleServer1Logs(LoggingMessageNotification notification) { // Handle logs from specific server logToFile("server1.log", notification); } @McpSampling(clients = "server1") public Mono handleAsyncSampling(CreateMessageRequest request) { return Mono.fromCallable(() -> { String response = generateLLMResponse(request); return CreateMessageResult.builder() .role(Role.ASSISTANT) .content(new TextContent(response)) .model("gpt-4") .build(); }).subscribeOn(Schedulers.boundedElastic()); } ---- For detailed information about all available annotations and their usage patterns, see the xref:api/mcp/mcp-annotations-client.adoc[MCP Client Annotations] documentation. == Usage Example Add the appropriate starter dependency to your project and configure the client in `application.properties` or `application.yml`: [source,yaml] ---- spring: ai: mcp: client: enabled: true name: my-mcp-client version: 1.0.0 request-timeout: 30s type: SYNC # or ASYNC for reactive applications sse: connections: server1: url: http://localhost:8080 server2: url: http://otherserver:8081 streamable-http: connections: server3: url: http://localhost:8083 endpoint: /mcp stdio: root-change-notification: false connections: server1: command: /path/to/server args: - --port=8080 - --mode=production env: API_KEY: your-api-key DEBUG: "true" ---- The MCP client beans will be automatically configured and available for injection: [source,java] ---- @Autowired private List mcpSyncClients;

The link:https://modelcontextprotocol.org/docs/concepts/architecture[Model Context Protocol] (MCP) is a standardized protocol that enables AI models to interact with external tools and resources in a structured way. Think of it as a bridge between your AI models and the real world - allowing them to access databases, APIs, file systems, and other external services through a consistent interface. It supports multiple transport mechanisms to provide flexibility across different environments. The link:https://modelcontextprotocol.io/sdk/java/mcp-overview[MCP Java SDK] provides a Java implementation of the Model Context Protocol, enabling standardized interaction with AI models and tools through both synchronous and asynchronous communication patterns. Spring AI embraces MCP with comprehensive support through dedicated Boot Starters and MCP Java Annotations, making it easier than ever to build sophisticated AI-powered applications that can seamlessly connect to external systems. This means Spring developers can participate in both sides of the MCP ecosystem - building AI applications that consume MCP servers and creating MCP servers that expose Spring-based services to the wider AI community. Bootstrap your AI applications with MCP support using link:https://start.spring.io[Spring Initializer]. == MCP Java SDK Architecture TIP: This section provides an overview for the link:https://modelcontextprotocol.io/sdk/java/mcp-overview[MCP Java SDK architecture]. For the Spring AI MCP integration, refer to the xref:#_spring_ai_mcp_integration[Spring AI MCP Boot Starters] documentation. The Java MCP implementation follows a three-layer architecture that separates concerns for maintainability and flexibility: .MCP Stack Architecture image::mcp/mcp-stack.svg[MCP Stack Architecture, align=center] === Client/Server Layer (Top) The top layer handles the main application logic and protocol operations: * *McpClient* - Manages client-side operations and server connections * *McpServer* - Handles server-side protocol operations and client requests * Both components utilize the session layer below for communication management === Session Layer (Middle) The middle layer manages communication patterns and maintains connection state: * *McpSession* - Core session management interface * *McpClientSession* - Client-specific session implementation * *McpServerSession* - Server-specific session implementation === Transport Layer (Bottom) The bottom layer handles the actual message transport and serialization: * *McpTransport* - Manages JSON-RPC message serialization and deserialization * Supports multiple transport implementations (STDIO, HTTP/SSE, Streamable-HTTP, etc.) * Provides the foundation for all higher-level communication |=== | link:https://modelcontextprotocol.io/sdk/java/mcp-client[MCP Client] | a| The MCP Client is a key component in the Model Context Protocol (MCP) architecture, responsible for establishing and managing connections with MCP servers.

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. === Maven Dependency Group ID Change The `mcp-spring-webflux` and `mcp-spring-webmvc` artifacts have moved from the `io.modelcontextprotocol.sdk` group to `org.springframework.ai`. .Before (MCP Java SDK < 1.0.x and Spring AI < 2.0.x) [source,xml] ---- io.modelcontextprotocol.sdk mcp-spring-webflux io.modelcontextprotocol.sdk mcp-spring-webmvc ---- .After (MCP Java SDK >= 1.0.x and Spring AI >= 2.0.x) [source,xml] ---- org.springframework.ai mcp-spring-webflux org.springframework.ai mcp-spring-webmvc ---- NOTE: 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. === Java Package Relocation All transport classes have been relocated to `org.springframework.ai` packages. .Server transport classes |=== |Class |Old package (MCP SDK) |New package (Spring AI) |`WebFluxSseServerTransportProvider` |`io.modelcontextprotocol.server.transport` |`org.springframework.ai.mcp.server.webflux.transport` |`WebFluxStreamableServerTransportProvider` |`io.modelcontextprotocol.server.transport` |`org.springframework.ai.mcp.server.webflux.transport` |`WebFluxStatelessServerTransport` |`io.modelcontextprotocol.server.transport` |`org.springframework.ai.mcp.server.webflux.transport` |`WebMvcSseServerTransportProvider` |`io.modelcontextprotocol.server.transport` |`org.springframework.ai.mcp.server.webmvc.transport` |`WebMvcStreamableServerTransportProvider` |`io.modelcontextprotocol.server.transport` |`org.springframework.ai.mcp.server.webmvc.transport` |`WebMvcStatelessServerTransport` |`io.modelcontextprotocol.server.transport` |`org.springframework.ai.mcp.server.webmvc.transport` |=== .Client transport classes |=== |Class |Old package (MCP SDK) |New package (Spring AI) |`WebFluxSseClientTransport` |`io.modelcontextprotocol.client.transport` |`org.springframework.ai.mcp.client.webflux.transport` |`WebClientStreamableHttpTransport` |`io.modelcontextprotocol.client.transport` |`org.springframework.ai.mcp.client.webflux.transport` |=== .Example import update [source,java] ---- // Before import io.modelcontextprotocol.server.transport.WebFluxSseServerTransportProvider; import io.modelcontextprotocol.server.transport.WebMvcSseServerTransportProvider; import io.modelcontextprotocol.client.transport.WebFluxSseClientTransport; import io.modelcontextprotocol.client.transport.WebClientStreamableHttpTransport; // After import org.springframework.ai.mcp.server.webflux.transport.WebFluxSseServerTransportProvider; import org.springframework.ai.mcp.server.webmvc.transport.WebMvcSseServerTransportProvider; import org.springframework.ai.mcp.client.webflux.transport.WebFluxSseClientTransport; import org.springframework.ai.mcp.client.webflux.transport.WebClientStreamableHttpTransport; ---- === MCP SDK Version Requirement Spring AI 2.0 requires **MCP Java SDK 1.0.0** (RC1 or later).

This community-driven project enables developers to secure both MCP servers and clients with industry-standard authentication and authorization mechanisms. NOTE: 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. This is a community-driven project and is not officially endorsed yet by Spring AI or the MCP project. == Overview The MCP Security module provides three main components: * *MCP Server Security* - OAuth 2.0 resource server and API key authentication for Spring AI MCP servers * *MCP Client Security* - OAuth 2.0 client support for Spring AI MCP clients * *MCP Authorization Server* - Enhanced Spring Authorization Server with MCP-specific features The project enables developers to: * Secure MCP servers with OAuth 2.0 authentication and API key-based access * Configure MCP clients with OAuth 2.0 authorization flows * Set up authorization servers specifically designed for MCP workflows * Implement fine-grained access control for MCP tools and resources == MCP Server Security The 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]. It also provides basic support for API-key based authentication. IMPORTANT: This module is compatible with Spring WebMVC-based servers only. === Dependencies Add the following dependencies to your project: [tabs] ====== Maven:: + [source,xml] ---- org.springaicommunity mcp-server-security org.springframework.boot spring-boot-starter-security org.springframework.boot spring-boot-starter-oauth2-resource-server ---- Gradle:: + [source,groovy] ---- implementation 'org.springaicommunity:mcp-server-security' implementation 'org.springframework.boot:spring-boot-starter-security' // OPTIONAL: For OAuth2 support implementation 'org.springframework.boot:spring-boot-starter-oauth2-resource-server' ---- ====== === OAuth 2.0 Configuration ==== Basic OAuth 2.0 Setup First, enable the MCP server in your `application.properties`: [source,properties] ---- spring.ai.mcp.server.name=my-cool-mcp-server # Supported protocols: STREAMABLE, STATELESS spring.ai.mcp.server.protocol=STREAMABLE ---- Then, configure security using Spring Security's standard APIs with the provided MCP configurer: [source,java] ---- @Configuration @EnableWebSecurity class McpServerConfiguration { @Value("${spring.security.oauth2.resourceserver.jwt.issuer-uri}") private String issuerUrl; @Bean SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { return http // Enforce authentication with token on EVERY request .authorizeHttpRequests(auth -> auth.anyRequest().authenticated()) // Configure OAuth2 on the MCP server .with( McpServerOAuth2Configurer.mcpServerOAuth2(), (mcpAuthorization) -> { // REQUIRED: the issuerURI mcpAuthorization.authorizationServer(issuerUrl); // OPTIONAL: enforce the `aud` claim in the JWT token. // Not all authorization servers support resource indicators, // so it may be absent. Defaults to `false`. // See RFC 8707 Resource Indicators for OAuth 2.0 // https://www.rfc-editor.org/rfc/rfc8707.html mcpAuthorization.validateAudienceClaim(true); } ) .build(); } } ---- ==== Securing Tool Calls Only You can configure the server to secure only tool calls while leaving other MCP operations (like `initialize` and `tools/list`) public: [source,java] ---- @Configuration @EnableWebSecurity @EnableMethodSecurity // Enable annotation-driven security class McpServerConfiguration { @Value("${spring.security.oauth2.resourceserver.jwt.issuer-uri}") private String issuerUrl; @Bean SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { return http // Open every request on the server .authorizeHttpRequests(auth -> { auth.requestMatcher("/mcp").permitAll(); auth.anyRequest().authenticated(); }) // Configure OAuth2 on the MCP server .with( McpResourceServerConfigurer.mcpServerOAuth2(), (mcpAuthorization) -> { // REQUIRED: the issuerURI mcpAuthorization.authorizationServer(issuerUrl); } ) .build(); } } ---- Then, secure your tool calls using the `@PreAuthorize` annotation with link:https://docs.spring.io/spring-security/reference/servlet/authorization/method-security.html[method security]: [source,java] ---- @Service public class MyToolsService { @PreAuthorize("isAuthenticated()") @McpTool(name = "greeter", description = "A tool that greets you, in the selected language") public String greet( @ToolParam(description = "The language for the greeting (example: english, french, ...)") String language ) { if (!StringUtils.hasText(language)) { language = ""; } return switch (language.toLowerCase()) { case "english" -> "Hello you!"; case "french" -> "Salut toi!"; default -> "I don't understand language \"%s\". So I'm just going to say Hello!".formatted(language); }; } } ---- You can also access the current authentication directly from the tool method using `SecurityContextHolder`: [source,java] ---- @McpTool(name = "greeter", description = "A tool that greets the user by name, in the selected language") @PreAuthorize("isAuthenticated()") public String greet( @ToolParam(description = "The language for the greeting (example: english, french, ...)") String language ) { if (!StringUtils.hasText(language)) { language = ""; } var authentication = SecurityContextHolder.getContext().getAuthentication(); var name = authentication.getName(); return switch (language.toLowerCase()) { case "english" -> "Hello, %s!".formatted(name); case "french" -> "Salut %s!".formatted(name); default -> ("I don't understand language \"%s\". " + "So I'm just going to say Hello %s!").formatted(language, name); }; } ---- === API Key Authentication The MCP Server Security module also supports API key-based authentication. You need to provide your own implementation of `ApiKeyEntityRepository` for storing `ApiKeyEntity` objects. A sample implementation is available with `InMemoryApiKeyEntityRepository` along with a default `ApiKeyEntityImpl`: WARNING: The `InMemoryApiKeyEntityRepository` uses bcrypt for storing API keys, which is computationally expensive. It is not suited for high-traffic production use. For production, implement your own `ApiKeyEntityRepository`. [source,java] ---- @Configuration @EnableWebSecurity class McpServerConfiguration { @Bean SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { return http.authorizeHttpRequests(authz -> authz.anyRequest().authenticated()) .with( mcpServerApiKey(), (apiKey) -> { // REQUIRED: the repo for API keys apiKey.apiKeyRepository(apiKeyRepository()); // OPTIONAL: name of the header containing the API key. // Here for example, api keys will be sent with "CUSTOM-API-KEY: " // Replaces .authenticationConverter(...) (see below) // // apiKey.headerName("CUSTOM-API-KEY"); // OPTIONAL: custom converter for transforming an http request // into an authentication object. Useful when the header is // "Authorization: Bearer ". // Replaces .headerName(...) (see above) // // apiKey.authenticationConverter(request -> { // var key = extractKey(request); // return ApiKeyAuthenticationToken.unauthenticated(key); // }); } ) .build(); } /** * Provide a repository of {@link ApiKeyEntity}. */ private ApiKeyEntityRepository apiKeyRepository() { var apiKey = ApiKeyEntityImpl.builder() .name("test api key") .id("api01") .secret("mycustomapikey") .build(); return new InMemoryApiKeyEntityRepository<>(List.of(apiKey)); } } ---- With this configuration, you can call your MCP server with a header `X-API-key: api01.mycustomapikey`. === Known Limitations [IMPORTANT] ==== * The deprecated SSE transport is not supported. Use xref:api/mcp/mcp-streamable-http-server-boot-starter-docs.adoc[Streamable HTTP] or xref:api/mcp/mcp-stateless-server-boot-starter-docs.adoc[stateless transport]. * WebFlux-based servers are not supported. * Opaque tokens are not supported. Use JWT. ==== == MCP Client Security The 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`). IMPORTANT: This module supports `McpSyncClient` only. === Dependencies [tabs] ====== Maven:: + [source,xml] ---- org.springaicommunity mcp-client-security ---- Gradle:: + [source,groovy] ---- implementation 'org.springaicommunity:mcp-client-security' ---- ====== === Authorization Flows Three OAuth 2.0 flows are available for obtaining tokens: * *Authorization Code Flow* - For user-level permissions when every MCP request is made within the context of a user request * *Client Credentials Flow* - For machine-to-machine use cases where no human is in the loop * *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 TIP: 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. === Common Setup For all flows, activate Spring Security's OAuth2 client support in your `application.properties`: [source,properties] ---- # Ensure MCP clients are sync spring.ai.mcp.client.type=SYNC # For authorization_code or hybrid flow spring.security.oauth2.client.registration.authserver.client-id= spring.security.oauth2.client.registration.authserver.client-secret= spring.security.oauth2.client.registration.authserver.authorization-grant-type=authorization_code spring.security.oauth2.client.registration.authserver.provider=authserver # For client_credentials or hybrid flow spring.security.oauth2.client.registration.authserver-client-credentials.client-id= spring.security.oauth2.client.registration.authserver-client-credentials.client-secret= spring.security.oauth2.client.registration.authserver-client-credentials.authorization-grant-type=client_credentials spring.security.oauth2.client.registration.authserver-client-credentials.provider=authserver # Authorization server configuration spring.security.oauth2.client.provider.authserver.issuer-uri= ---- Then, create a configuration class activating OAuth2 client capabilities: [source,java] ---- @Configuration @EnableWebSecurity class SecurityConfiguration { @Bean SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { return http // in this example, the client app has no security on its endpoints .authorizeHttpRequests(auth -> auth.anyRequest().permitAll()) // turn on OAuth2 support .oauth2Client(Customizer.withDefaults()) .build(); } } ---- === HttpClient-Based Clients When using `spring-ai-starter-mcp-client`, configure a `McpSyncHttpClientRequestCustomizer` bean: [source,java] ---- @Configuration class McpConfiguration { @Bean McpCustomizer syncClientCustomizer() { return (name, syncSpec) -> syncSpec.transportContextProvider( new AuthenticationMcpTransportContextProvider() ); } @Bean McpSyncHttpClientRequestCustomizer requestCustomizer( OAuth2AuthorizedClientManager clientManager ) { // The clientRegistration name, "authserver", // must match the name in application.properties return new OAuth2AuthorizationCodeSyncHttpRequestCustomizer( clientManager, "authserver" ); } } ---- Available customizers: * `OAuth2AuthorizationCodeSyncHttpRequestCustomizer` - For authorization code flow * `OAuth2ClientCredentialsSyncHttpRequestCustomizer` - For client credentials flow * `OAuth2HybridSyncHttpRequestCustomizer` - For hybrid flow === WebClient-Based Clients When using `spring-ai-starter-mcp-client-webflux`, configure a `WebClient.Builder` with an MCP `ExchangeFilterFunction`: [source,java] ---- @Configuration class McpConfiguration { @Bean McpCustomizer syncClientCustomizer() { return (name, syncSpec) -> syncSpec.transportContextProvider( new AuthenticationMcpTransportContextProvider() ); } @Bean WebClient.Builder mcpWebClientBuilder(OAuth2AuthorizedClientManager clientManager) { // The clientRegistration name, "authserver", must match the name in application.properties return WebClient.builder().filter( new McpOAuth2AuthorizationCodeExchangeFilterFunction( clientManager, "authserver" ) ); } } ---- Available filter functions: * `McpOAuth2AuthorizationCodeExchangeFilterFunction` - For authorization code flow * `McpOAuth2ClientCredentialsExchangeFilterFunction` - For client credentials flow * `McpOAuth2HybridExchangeFilterFunction` - For hybrid flow === Working Around Spring AI Autoconfiguration Spring AI's autoconfiguration initializes MCP clients at startup, which can cause issues with user-based authentication. To avoid this: ==== Option 1: Disable @Tool Auto-configuration Disable Spring AI's `@Tool` autoconfiguration by publishing an empty `ToolCallbackResolver` bean: [source,java] ---- @Configuration public class McpConfiguration { @Bean ToolCallbackResolver resolver() { return new StaticToolCallbackResolver(List.of()); } } ---- ==== Option 2: Programmatic Client Configuration Configure MCP clients programmatically instead of using Spring Boot properties. For HttpClient-based clients: [source,java] ---- @Bean McpSyncClient client( JsonMapper jsonMapper, McpSyncHttpClientRequestCustomizer requestCustomizer, McpClientCommonProperties commonProps ) { var transport = HttpClientStreamableHttpTransport.builder(mcpServerUrl) .clientBuilder(HttpClient.newBuilder()) .jsonMapper(new JacksonMcpJsonMapper(jsonMapper)) .httpRequestCustomizer(requestCustomizer) .build(); var clientInfo = new McpSchema.Implementation("client-name", commonProps.getVersion()); return McpClient.sync(transport) .clientInfo(clientInfo) .requestTimeout(commonProps.getRequestTimeout()) .transportContextProvider(new AuthenticationMcpTransportContextProvider()) .build(); } ---- For WebClient-based clients: [source,java] ---- @Bean McpSyncClient client( WebClient.Builder mcpWebClientBuilder, JsonMapper jsonMapper, McpClientCommonProperties commonProperties ) { var builder = mcpWebClientBuilder.baseUrl(mcpServerUrl); var transport = WebClientStreamableHttpTransport.builder(builder) .jsonMapper(new JacksonMcpJsonMapper(jsonMapper)) .build(); var clientInfo = new McpSchema.Implementation("clientName", commonProperties.getVersion()); return McpClient.sync(transport) .clientInfo(clientInfo) .requestTimeout(commonProperties.getRequestTimeout()) .transportContextProvider(new AuthenticationMcpTransportContextProvider()) .build(); } ---- Then add the client to your chat client: [source,java] ---- var chatResponse = chatClient.prompt("Prompt the LLM to do the thing") .toolCallbacks(new SyncMcpToolCallbackProvider(mcpClient1, mcpClient2, mcpClient3)) .call() .content(); ---- === Known Limitations [IMPORTANT] ==== * Spring WebFlux servers are not supported. * Spring AI autoconfiguration initializes MCP clients at app start, requiring workarounds for user-based authentication. * Unlike the server module, the client implementation supports the SSE transport with both `HttpClient` and `WebClient`. ==== == MCP Authorization Server The 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. === Dependencies [tabs] ====== Maven:: + [source,xml] ---- org.springaicommunity mcp-authorization-server ---- Gradle:: + [source,groovy] ---- implementation 'org.springaicommunity:mcp-authorization-server' ---- ====== === Configuration Configure the authorization server in your `application.yml`: [source,yaml] ---- spring: application: name: sample-authorization-server security: oauth2: authorizationserver: client: default-client: token: access-token-time-to-live: 1h registration: client-id: "default-client" client-secret: "{noop}default-secret" client-authentication-methods: - "client_secret_basic" - "none" authorization-grant-types: - "authorization_code" - "client_credentials" redirect-uris: - "http://127.0.0.1:8080/authorize/oauth2/code/authserver" - "http://localhost:8080/authorize/oauth2/code/authserver" # mcp-inspector - "http://localhost:6274/oauth/callback" # claude code - "https://claude.ai/api/mcp/auth_callback" user: # A single user, named "user" name: user password: password server: servlet: session: cookie: # Override the default cookie name (JSESSIONID). # This allows running multiple Spring apps on localhost, and they'll each have their own cookie. # Otherwise, since the cookies do not take the port into account, they are confused. name: MCP_AUTHORIZATION_SERVER_SESSIONID ---- Then activate the authorization server capabilities with a security filter chain: [source,java] ---- @Bean SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { return http // all requests must be authenticated .authorizeHttpRequests(auth -> auth.anyRequest().authenticated()) // enable authorization server customizations .with(McpAuthorizationServerConfigurer.mcpAuthorizationServer(), withDefaults()) // enable form-based login, for user "user"/"password" .formLogin(withDefaults()) .build(); } ---- === Known Limitations [IMPORTANT] ==== * Spring WebFlux servers are not supported. * Every client supports ALL `resource` identifiers. ==== == Samples and Integrations The link:https://github.com/spring-ai-community/mcp-security/tree/main/samples[samples directory] contains working examples for all modules in this project, including integration tests.

Each server provides focused functionality for a particular domain. The Spring AI MCP Server Boot Starters provide auto-configuration for setting up link:https://modelcontextprotocol.io/docs/learn/server-concepts[MCP Servers] in Spring Boot applications. They enable seamless integration of MCP server capabilities with Spring Boot's auto-configuration system. The MCP Server Boot Starters offer: * Automatic configuration of MCP server components, including tools, resources, and prompts * Support for different MCP protocol versions, including STDIO, SSE, Streamable-HTTP, and stateless servers * Support for both synchronous and asynchronous operation modes * Multiple transport layer options * Flexible tool, resource, and prompt specification * Change notification capabilities * xref:api/mcp/mcp-annotations-server.adoc[Annotation-based server development] with automatic bean scanning and registration == MCP Server Boot Starters MCP Servers support multiple protocol and transport mechanisms.

Disabling a capability will prevent the server from registering and exposing the corresponding features to clients. == Server Protocols MCP provides several protocol types including: * 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`. * 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. * 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`. * 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. They are ideal for microservices architectures and cloud-native deployments. To enable the `STATELESS` protocol, set `spring.ai.mcp.server.protocol=STATELESS`. == Sync/Async Server API Options The MCP Server API supports imperative (i.e. synchronous) and reactive (e.g. asynchronous) programming models. * **Synchronous Server** - The default server type implemented using `McpSyncServer`. It is designed for straightforward request-response patterns in your applications. To enable this server type, set `spring.ai.mcp.server.type=SYNC` in your configuration. When activated, it automatically handles the configuration of synchronous tool specifications. **NOTE:** The SYNC server will register only synchronous MCP annotated methods. Asynchronous methods will be ignored. * **Asynchronous Server** - The asynchronous server implementation uses `McpAsyncServer` and is optimized for non-blocking operations. To enable this server type, configure your application with `spring.ai.mcp.server.type=ASYNC`. This server type automatically sets up asynchronous tool specifications with built-in Project Reactor support. **NOTE:** The ASYNC server will register only asynchronous MCP annotated methods. Synchronous methods will be ignored. == MCP Server Annotations The 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. === Key Annotations * **xref:api/mcp/mcp-annotations-server.adoc#_mcptool[@McpTool]** - Mark methods as MCP tools with automatic JSON schema generation * **xref:api/mcp/mcp-annotations-server.adoc#_mcpresource[@McpResource]** - Provide access to resources via URI templates * **xref:api/mcp/mcp-annotations-server.adoc#_mcpprompt[@McpPrompt]** - Generate prompt messages for AI interactions * **xref:api/mcp/mcp-annotations-server.adoc#_mcpcomplete[@McpComplete]** - Provide auto-completion functionality for prompts === Special Parameters The annotation system supports xref:api/mcp/mcp-annotations-special-params.adoc[special parameter types] that provide additional context: * **`McpMeta`** - Access metadata from MCP requests * **`@McpProgressToken`** - Receive progress tokens for long-running operations * **`McpSyncServerExchange`/`McpAsyncServerExchange`** - Full server context for advanced operations * **`McpTransportContext`** - Lightweight context for stateless operations * **`CallToolRequest`** - Dynamic schema support for flexible tools === Simple Example [source,java] ---- @Component public class CalculatorTools { @McpTool(name = "add", description = "Add two numbers together") public int add( @McpToolParam(description = "First number", required = true) int a, @McpToolParam(description = "Second number", required = true) int b) { return a + b; } @McpResource(uri = "config://{key}", name = "Configuration") public String getConfig(String key) { return configData.get(key); } } ---- === Adding data to McpTransportContext By default, the `McpTransportContext` is empty (`McpTransportContext.EMPTY`). This is by design, to keep the MCP server transport-agnostic. If you need transport-specific metadata (for example, HTTP headers, remote host, etc) in your tools, configure a `TransportContextExtractor` on your transport provider. [source,java] ---- @Bean public WebMvcStreamableServerTransportProvider transport(ObjectMapper objectMapper) { return WebMvcStreamableServerTransportProvider.builder() .contextExtractor(serverRequest -> { String authorization = serverRequest.headers().firstHeader("Authorization"); return McpTransportContext.create(Map.of("authorization", authorization)); }) .build(); } ---- Once configured, access the context via `McpSyncRequestContext` (or `McpAsyncRequestContext`) in your tool. [source,java] ---- @McpTool public String accessProtectedResource(McpSyncRequestContext requestContext) { McpTransportContext context = requestContext.transportContext(); String authorization = (String) context.get("authorization"); return "Successfully accessed protected resource."; } ---- === Auto-Configuration With Spring Boot auto-configuration, annotated beans are automatically detected and registered: [source,java] ---- @SpringBootApplication public class McpServerApplication { public static void main(String[] args) { SpringApplication.run(McpServerApplication.class, args); } } ---- The auto-configuration will: 1. Scan for beans with MCP annotations 2. Create appropriate specifications 3. Register them with the MCP server 4. Handle both sync and async implementations based on configuration === Configuration Properties Configure the server annotation scanner: [source,yaml] ---- spring: ai: mcp: server: type: SYNC # or ASYNC annotation-scanner: enabled: true ---- === Additional Resources * xref:api/mcp/mcp-annotations-server.adoc[Server Annotations Reference] - Complete guide to server annotations * xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters] - Advanced parameter injection * xref:api/mcp/mcp-annotations-examples.adoc[Examples] - Comprehensive examples and use cases == Example Applications * 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 * 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 * 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 * Streamable-HTTP WebFlux/WebMVC Example - TODO * Stateless WebFlux/WebMVC Example - TODO == Additional Resources * xref:api/mcp/mcp-annotations-server.adoc[MCP Server Annotations] - Declarative server development with annotations * xref:api/mcp/mcp-annotations-special-params.adoc[Special Parameters] - Advanced parameter injection and context access * xref:api/mcp/mcp-annotations-examples.adoc[MCP Annotations Examples] - Comprehensive examples and use cases * link:https://docs.spring.io/spring-ai/reference/[Spring AI Documentation] * link:https://modelcontextprotocol.io/specification[Model Context Protocol Specification] * link:https://docs.spring.io/spring-boot/docs/current/reference/html/features.html#features.developing-auto-configuration[Spring Boot Auto-configuration] ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/mcp/mcp-stateless-server-boot-starter-docs.adoc ================================================ == Stateless Streamable-HTTP MCP Servers Stateless Streamable-HTTP MCP servers are designed for simplified deployments where session state is not maintained between requests.

The way we learn, our experiences are all multimodal. We don't have just vision, just audio and just text. Contrary to those principles, the Machine Learning was often focused on specialized models tailored to process a single modality. For instance, we developed audio models for tasks like text-to-speech or speech-to-text, and computer vision models for tasks such as object detection and classification. However, a new wave of multimodal large language models starts to emerge. Examples include OpenAI's GPT, Google's Gemini, Anthropic's Claude, and open source offerings Llama, LLaVA and BakLLaVA are able to accept multiple inputs, including text images, audio and video and generate text responses by integrating these inputs. NOTE: The multimodal large language model (LLM) features enable the models to process and generate text in conjunction with other modalities such as images, audio, or video. == Spring AI Multimodality Multimodality refers to a model’s ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats. The Spring AI Message API provides all necessary abstractions to support multimodal LLMs. image::spring-ai-message-api.jpg[Spring AI Message API, width=800, align="center"] The UserMessage’s `content` field is used primarily for text inputs, while the optional `media` field allows adding one or more additional content of different modalities such as images, audio and video. The `MimeType` specifies the modality type. Depending on the used LLMs, the `Media` data field can be either the raw media content as a `Resource` object or a `URI` to the content. NOTE: The media field is currently applicable only for user input messages (e.g., `UserMessage`). 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.* For example, we can take the following picture (`multimodal.test.png`) as an input and ask the LLM to explain what it sees. image::multimodal.test.png[Multimodal Test Image, 200, 200, align="left"] For most of the multimodal LLMs, the Spring AI code would look something like this: [source,java] ---- var imageResource = new ClassPathResource("/multimodal.test.png"); var userMessage = UserMessage.builder() .text("Explain what do you see in this picture?") // content .media(new Media(MimeTypeUtils.IMAGE_PNG, this.imageResource)) // media .build(); ChatResponse response = chatModel.call(new Prompt(this.userMessage)); ---- or with the fluent xref::api/chatclient.adoc[ChatClient] API: [source,java] ---- String response = ChatClient.create(chatModel).prompt() .user(u -> u.text("Explain what do you see on this picture?") .media(MimeTypeUtils.IMAGE_PNG, new ClassPathResource("/multimodal.test.png"))) .call() .content(); ---- and produce a response like: > This is an image of a fruit bowl with a simple design. The bowl is made of metal with curved wire edges that create an open structure, allowing the fruit to be visible from all angles. Inside the bowl, there are two yellow bananas resting on top of what appears to be a red apple. The bananas are slightly overripe, as indicated by the brown spots on their peels. The bowl has a metal ring at the top, likely to serve as a handle for carrying. The bowl is placed on a flat surface with a neutral-colored background that provides a clear view of the fruit inside. Spring AI provides multimodal support for the following chat models: * xref:api/chat/anthropic-chat.adoc#_multi_modal_support[Anthropic Claude] * xref:api/chat/bedrock-converse.adoc#_multimodal[AWS Bedrock Converse] * xref:api/chat/azure-openai-chat.adoc#_multimodal[Azure Open AI (e.g. GPT models)] * xref:api/chat/mistralai-chat.adoc#_multimodal[Mistral AI (e.g. Mistral Pixtral models)] * xref:api/chat/ollama-chat.adoc#_multimodal[Ollama (e.g. LLaVA, BakLLaVA, Llama models)] * xref:api/chat/openai-chat.adoc#_multimodal[OpenAI (e.g. GPT models)] * xref:api/chat/google-genai-chat.adoc#_multimodal[Google Gemini] ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/prompt.adoc ================================================ [[prompts]] = Prompts Prompts are the inputs that guide an AI model to generate specific outputs. The design and phrasing of these prompts significantly influence the model's responses. At 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. This involves creating extensive text with placeholders for dynamic content. These placeholders are then replaced based on user requests or other code in the application. Another analogy is a SQL statement that contain placeholders for certain expressions. As Spring AI evolves, it will introduce higher levels of abstraction for interacting with AI models. The foundational classes described in this section can be likened to JDBC in terms of their role and functionality. The `ChatModel` class, for instance, is analogous to the core JDBC library in the JDK. The `ChatClient` class can be likened to the `JdbcClient`, built on top of `ChatModel` and providing more advanced constructs via `Advisor` to consider past interactions with the model, augment the prompt with additional contextual documents, and introduce agentic behavior. The structure of prompts has evolved over time within the AI field. Initially, prompts were simple strings. Over time, they grew to include placeholders for specific inputs, like "USER:", which the AI model recognizes. OpenAI have introduced even more structure to prompts by categorizing multiple message strings into distinct roles before they are processed by the AI model. == API Overview === Prompt It is common to use the `call()` method of `ChatModel` that takes a `Prompt` instance and returns a `ChatResponse`. The `Prompt` class functions as a container for an organized series of `Message` objects and a request `ChatOptions`. Every `Message` embodies a unique role within the prompt, differing in its content and intent. These roles can encompass a variety of elements, from user inquiries to AI-generated responses to relevant background information. This 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. Below is a truncated version of the Prompt class, with constructors and utility methods omitted for brevity: [source,java] ---- public class Prompt implements ModelRequest> { private final List messages; private ChatOptions chatOptions; } ---- ==== Convenience Methods The `Prompt` class provides several convenience methods for accessing messages by their role: **Single Message Access:** * `getUserMessage()`: Returns the last user message in the prompt, or an empty `UserMessage` if none exists * `getSystemMessage()`: Returns the first system message in the prompt, or an empty `SystemMessage` if none exists * `getLastUserOrToolResponseMessage()`: Returns the last user or tool response message, useful for conversation continuity **Multiple Message Access:** * `getUserMessages()`: Returns a list of all user messages in the prompt, preserving their order * `getSystemMessages()`: Returns a list of all system messages in the prompt, preserving their order These methods are particularly useful when working with multi-turn conversations or when you need to process messages by role. === Message The `Message` interface encapsulates a `Prompt` textual content, a collection of metadata attributes, and a categorization known as `MessageType`. The interface is defined as follows: [source,java] ---- public interface Content { String getContent(); Map getMetadata(); } public interface Message extends Content { MessageType getMessageType(); } ---- The multimodal message types implement also the `MediaContent` interface providing a list of `Media` content objects. [source,java] ---- public interface MediaContent extends Content { Collection getMedia(); } ---- Various implementations of the `Message` interface correspond to different categories of messages that an AI model can process. The Models distinguish between message categories based on conversational roles. image::spring-ai-message-api.jpg[Spring AI Message API, width=800, align="center"] These roles are effectively mapped by the `MessageType`, as discussed below. ==== Roles Each message is assigned a specific role. These roles categorize the messages, clarifying the context and purpose of each segment of the prompt for the AI model. This 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. The primary roles are: * 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. * 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. * Assistant Role: The AI's response to the user's input. More than just an answer or reaction, it's crucial for maintaining the flow of the conversation. By tracking the AI's previous responses (its 'Assistant Role' messages), the system ensures coherent and contextually relevant interactions. The Assistant message may contain Function Tool Call request information as well. It'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. * Tool/Function Role: The Tool/Function Role focuses on returning additional information in response to Tool Call Assistant Messages. Roles are represented as an enumeration in Spring AI as shown below [source,java] ---- public enum MessageType { USER("user"), ASSISTANT("assistant"), SYSTEM("system"), TOOL("tool"); ... } ---- === PromptTemplate A 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 [source,java] ---- public class PromptTemplate implements PromptTemplateActions, PromptTemplateMessageActions { // Other methods to be discussed later } ---- This 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. [source,java] ---- public interface TemplateRenderer extends BiFunction, String> { @Override String apply(String template, Map variables); } ---- Spring AI uses the `TemplateRenderer` interface to handle the actual substitution of variables into the template string. The default implementation uses <>. You can provide your own implementation of `TemplateRenderer` if you need custom logic. For scenarios where no template rendering is required (e.g., the template string is already complete), you can use the provided `NoOpTemplateRenderer`. .Example using a custom StringTemplate renderer with '<' and '>' delimiters [source,java] ---- PromptTemplate promptTemplate = PromptTemplate.builder() .renderer(StTemplateRenderer.builder().startDelimiterToken('<').endDelimiterToken('>').build()) .template(""" Tell me the names of 5 movies whose soundtrack was composed by . """) .build(); String prompt = promptTemplate.render(Map.of("composer", "John Williams")); ---- The interfaces implemented by this class support different aspects of prompt creation: `PromptTemplateStringActions` focuses on creating and rendering prompt strings, representing the most basic form of prompt generation. `PromptTemplateMessageActions` is tailored for prompt creation through the generation and manipulation of `Message` objects. `PromptTemplateActions` is designed to return the `Prompt` object, which can be passed to `ChatModel` for generating a response. While these interfaces might not be used extensively in many projects, they show the different approaches to prompt creation. The implemented interfaces are [source,java] ---- public interface PromptTemplateStringActions { String render(); String render(Map model); } ---- The method `String render()`: Renders a prompt template into a final string format without external input, suitable for templates without placeholders or dynamic content. The method `String render(Map model)`: Enhances rendering functionality to include dynamic content. It uses a `Map` where map keys are placeholder names in the prompt template, and values are the dynamic content to be inserted. [source,java] ---- public interface PromptTemplateMessageActions { Message createMessage(); Message createMessage(List mediaList); Message createMessage(Map model); } ---- The method `Message createMessage()`: Creates a `Message` object without additional data, used for static or predefined message content. The method `Message createMessage(List mediaList)`: Creates a `Message` object with static textual and media content. The method `Message createMessage(Map model)`: Extends message creation to integrate dynamic content, accepting a `Map` where each entry represents a placeholder in the message template and its corresponding dynamic value. [source,java] ---- public interface PromptTemplateActions extends PromptTemplateStringActions { Prompt create(); Prompt create(ChatOptions modelOptions); Prompt create(Map model); Prompt create(Map model, ChatOptions modelOptions); } ---- The method `Prompt create()`: Generates a `Prompt` object without external data inputs, ideal for static or predefined prompts. The method `Prompt create(ChatOptions modelOptions)`: Generates a `Prompt` object without external data inputs and with specific options for the chat request. The method `Prompt create(Map model)`: Expands prompt creation capabilities to include dynamic content, taking a `Map` where each map entry is a placeholder in the prompt template and its associated dynamic value. The method `Prompt create(Map model, ChatOptions modelOptions)`: Expands prompt creation capabilities to include dynamic content, taking a `Map` where each map entry is a placeholder in the prompt template and its associated dynamic value, and specific options for the chat request. == Example Usage A 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. [source,java] ---- PromptTemplate promptTemplate = new PromptTemplate("Tell me a {adjective} joke about {topic}"); Prompt prompt = promptTemplate.create(Map.of("adjective", adjective, "topic", topic)); return chatModel.call(prompt).getResult(); ---- Another 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. [source,java] ---- String userText = """ Tell me about three famous pirates from the Golden Age of Piracy and why they did. Write at least a sentence for each pirate. """; Message userMessage = new UserMessage(userText); String systemText = """ You are a helpful AI assistant that helps people find information. Your name is {name} You should reply to the user's request with your name and also in the style of a {voice}. """; SystemPromptTemplate systemPromptTemplate = new SystemPromptTemplate(systemText); Message systemMessage = systemPromptTemplate.createMessage(Map.of("name", name, "voice", voice)); Prompt prompt = new Prompt(List.of(userMessage, systemMessage)); List response = chatModel.call(prompt).getResults(); ---- This 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. The message with the role `user` is then combined with the message of the role `system` to form the prompt. The prompt is then passed to the ChatModel to get a generative response. === Using a custom template renderer You 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. By 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. [source,java] ---- PromptTemplate promptTemplate = PromptTemplate.builder() .renderer(StTemplateRenderer.builder().startDelimiterToken('<').endDelimiterToken('>').build()) .template(""" Tell me the names of 5 movies whose soundtrack was composed by . """) .build(); String prompt = promptTemplate.render(Map.of("composer", "John Williams")); ---- === Using resources instead of raw Strings Spring 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`. For example, you can define a field in your Spring managed component to retrieve the `Resource`. [source,java] ---- @Value("classpath:/prompts/system-message.st") private Resource systemResource; ---- and then pass that resource to the `SystemPromptTemplate` directly. [source,java] ---- SystemPromptTemplate systemPromptTemplate = new SystemPromptTemplate(systemResource); ---- == Prompt Engineering In generative AI, the creation of prompts is a crucial task for developers. The quality and structure of these prompts significantly influence the effectiveness of the AI's output. Investing time and effort in designing thoughtful prompts can greatly improve the results from the AI. Sharing and discussing prompts is a common practice in the AI community. This collaborative approach not only creates a shared learning environment but also leads to the identification and use of highly effective prompts. Research in this area often involves analyzing and comparing different prompts to assess their effectiveness in various situations. For 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. This highlights the impact that well-chosen language can have on generative AI systems' performance. Grasping the most effective use of prompts, particularly with the rapid advancement of AI technologies, is a continuous challenge. You should recognize the importance of prompt engineering and consider using insights from the community and research to improve prompt creation strategies. === Creating effective prompts When developing prompts, it's important to integrate several key components to ensure clarity and effectiveness: * *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. * *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. * *User Input*: This is the straightforward part - the user's direct request or question forming the core of the prompt. * *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. Providing the AI with examples of the anticipated question and answer format can be highly beneficial when crafting prompts. This practice helps the AI "understand" the structure and intent of your query, leading to more precise and relevant responses. While this documentation does not delve deeply into these techniques, they provide a starting point for further exploration in AI prompt engineering. Following is a list of resources for further investigation. ==== Simple Techniques * *https://www.promptingguide.ai/introduction/examples.en#text-summarization[Text Summarization]*: + Reduces extensive text into concise summaries, capturing key points and main ideas while omitting less critical details. * *https://www.promptingguide.ai/introduction/examples.en#question-answering[Question Answering]*: + Focuses on deriving specific answers from provided text, based on user-posed questions.

This framework guides users in creating effective prompts that elicit the desired responses from AI models, optimizing the interaction for clarity and efficiency. == Tokens Tokens 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. This conversion occurs in two stages: words are transformed into tokens upon input, and these tokens are then converted back into words in the output. Tokenization, the process of breaking down text into tokens, is fundamental to how AI models comprehend and process language. The AI model works with this tokenized format to understand and respond to prompts. To 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. Experiment with the https://platform.openai.com/tokenizer[OpenAI Tokenizer UI] to see how words are converted into tokens. Tokens have practical implications beyond their technical role in AI processing, especially regarding billing and model capabilities: * 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. * 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. * 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. * 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. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/retrieval-augmented-generation.adoc ================================================ [[rag]] = Retrieval Augmented Generation Retrieval Augmented Generation (RAG) is a technique useful to overcome the limitations of large language models that struggle with long-form content, factual accuracy, and context-awareness. Spring AI supports RAG by providing a modular architecture that allows you to build custom RAG flows yourself or use out-of-the-box RAG flows using the `Advisor` API. NOTE: Learn more about Retrieval Augmented Generation in the xref:concepts.adoc#concept-rag[concepts] section. == Advisors Spring AI provides out-of-the-box support for common RAG flows using the `Advisor` API. To use the `QuestionAnswerAdvisor` or `VectorStoreChatMemoryAdvisor`, you need to add the `spring-ai-advisors-vector-store` dependency to your project: [source,xml] ---- org.springframework.ai spring-ai-advisors-vector-store ---- === QuestionAnswerAdvisor A 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. The response from the vector database is appended to the user text to provide context for the AI model to generate a response. Assuming you have already loaded data into a `VectorStore`, you can perform Retrieval Augmented Generation (RAG) by providing an instance of `QuestionAnswerAdvisor` to the `ChatClient`. [source,java] ---- ChatResponse response = ChatClient.builder(chatModel) .build().prompt() .advisors(QuestionAnswerAdvisor.builder(vectorStore).build()) .user(userText) .call() .chatResponse(); ---- In 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`. This 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. Here is how to create an instance of `QuestionAnswerAdvisor` where the threshold is `0.8` and to return the top `6` results. [source,java] ---- var qaAdvisor = QuestionAnswerAdvisor.builder(vectorStore) .searchRequest(SearchRequest.builder().similarityThreshold(0.8d).topK(6).build()) .build(); ---- ==== Dynamic Filter Expressions Update the `SearchRequest` filter expression at runtime using the `FILTER_EXPRESSION` advisor context parameter: [source,java] ---- ChatClient chatClient = ChatClient.builder(chatModel) .defaultAdvisors(QuestionAnswerAdvisor.builder(vectorStore) .searchRequest(SearchRequest.builder().build()) .build()) .build(); // Update filter expression at runtime String content = this.chatClient.prompt() .user("Please answer my question XYZ") .advisors(a -> a.param(QuestionAnswerAdvisor.FILTER_EXPRESSION, "type == 'Spring'")) .call() .content(); ---- The `FILTER_EXPRESSION` parameter allows you to dynamically filter the search results based on the provided expression. ==== Custom Template The `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. NOTE: 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. The 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: * a `query` placeholder to receive the user question. * a `question_answer_context` placeholder to receive the retrieved context. [source,java] ---- PromptTemplate customPromptTemplate = PromptTemplate.builder() .renderer(StTemplateRenderer.builder().startDelimiterToken('<').endDelimiterToken('>').build()) .template(""" Context information is below. --------------------- --------------------- Given the context information and no prior knowledge, answer the query. Follow these rules: 1. If the answer is not in the context, just say that you don't know. 2. Avoid statements like "Based on the context..." or "The provided information...". """) .build(); String question = "Where does the adventure of Anacletus and Birba take place?"; QuestionAnswerAdvisor qaAdvisor = QuestionAnswerAdvisor.builder(vectorStore) .promptTemplate(customPromptTemplate) .build(); String response = ChatClient.builder(chatModel).build() .prompt(question) .advisors(qaAdvisor) .call() .content(); ---- NOTE: The `QuestionAnswerAdvisor.Builder.userTextAdvise()` method is deprecated in favor of using `.promptTemplate()` for more flexible customization. === RetrievalAugmentationAdvisor Spring AI includes a xref:api/retrieval-augmented-generation.adoc#modules[library of RAG modules] that you can use to build your own RAG flows. The `RetrievalAugmentationAdvisor` is an `Advisor` providing an out-of-the-box implementation for the most common RAG flows, based on a modular architecture. To use the `RetrievalAugmentationAdvisor`, you need to add the `spring-ai-rag` dependency to your project: [source,xml] ---- org.springframework.ai spring-ai-rag ---- ==== Sequential RAG Flows ===== Naive RAG [source,java] ---- Advisor retrievalAugmentationAdvisor = RetrievalAugmentationAdvisor.builder() .documentRetriever(VectorStoreDocumentRetriever.builder() .similarityThreshold(0.50) .vectorStore(vectorStore) .build()) .build(); String answer = chatClient.prompt() .advisors(retrievalAugmentationAdvisor) .user(question) .call() .content(); ---- By default, the `RetrievalAugmentationAdvisor` does not allow the retrieved context to be empty. When that happens, it instructs the model not to answer the user query. You can allow empty context as follows. [source,java] ---- Advisor retrievalAugmentationAdvisor = RetrievalAugmentationAdvisor.builder() .documentRetriever(VectorStoreDocumentRetriever.builder() .similarityThreshold(0.50) .vectorStore(vectorStore) .build()) .queryAugmenter(ContextualQueryAugmenter.builder() .allowEmptyContext(true) .build()) .build(); String answer = chatClient.prompt() .advisors(retrievalAugmentationAdvisor) .user(question) .call() .content(); ---- The `VectorStoreDocumentRetriever` accepts a `FilterExpression` to filter the search results based on metadata. You can provide one when instantiating the `VectorStoreDocumentRetriever` or at runtime per request, using the `FILTER_EXPRESSION` advisor context parameter. [source,java] ---- Advisor retrievalAugmentationAdvisor = RetrievalAugmentationAdvisor.builder() .documentRetriever(VectorStoreDocumentRetriever.builder() .similarityThreshold(0.50) .vectorStore(vectorStore) .build()) .build(); String answer = chatClient.prompt() .advisors(retrievalAugmentationAdvisor) .advisors(a -> a.param(VectorStoreDocumentRetriever.FILTER_EXPRESSION, "type == 'Spring'")) .user(question) .call() .content(); ---- See xref:api/retrieval-augmented-generation.adoc#_vectorstoredocumentretriever[VectorStoreDocumentRetriever] for more information. ===== Advanced RAG [source,java] ---- Advisor retrievalAugmentationAdvisor = RetrievalAugmentationAdvisor.builder() .queryTransformers(RewriteQueryTransformer.builder() .chatClientBuilder(chatClientBuilder.build().mutate()) .build()) .documentRetriever(VectorStoreDocumentRetriever.builder() .similarityThreshold(0.50) .vectorStore(vectorStore) .build()) .build(); String answer = chatClient.prompt() .advisors(retrievalAugmentationAdvisor) .user(question) .call() .content(); ---- You 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. [[modules]] == Modules Spring AI implements a Modular RAG architecture inspired by the concept of modularity detailed in the paper "https://arxiv.org/abs/2407.21059[Modular RAG: Transforming RAG Systems into LEGO-like Reconfigurable Frameworks]". === Pre-Retrieval Pre-Retrieval modules are responsible for processing the user query to achieve the best possible retrieval results. ==== Query Transformation A component for transforming the input query to make it more effective for retrieval tasks, addressing challenges such as poorly formed queries, ambiguous terms, complex vocabulary, or unsupported languages. IMPORTANT: 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. ===== CompressionQueryTransformer A `CompressionQueryTransformer` uses a large language model to compress a conversation history and a follow-up query into a standalone query that captures the essence of the conversation. This transformer is useful when the conversation history is long and the follow-up query is related to the conversation context. [source,java] ---- Query query = Query.builder() .text("And what is its second largest city?") .history(new UserMessage("What is the capital of Denmark?"), new AssistantMessage("Copenhagen is the capital of Denmark.")) .build(); QueryTransformer queryTransformer = CompressionQueryTransformer.builder() .chatClientBuilder(chatClientBuilder) .build(); Query transformedQuery = queryTransformer.transform(query); ---- The prompt used by this component can be customized via the `promptTemplate()` method available in the builder. ===== RewriteQueryTransformer A `RewriteQueryTransformer` uses a large language model to rewrite a user query to provide better results when querying a target system, such as a vector store or a web search engine. This transformer is useful when the user query is verbose, ambiguous, or contains irrelevant information that may affect the quality of the search results. [source,java] ---- Query query = new Query("I'm studying machine learning. What is an LLM?"); QueryTransformer queryTransformer = RewriteQueryTransformer.builder() .chatClientBuilder(chatClientBuilder) .build(); Query transformedQuery = queryTransformer.transform(query); ---- The prompt used by this component can be customized via the `promptTemplate()` method available in the builder. ===== TranslationQueryTransformer A `TranslationQueryTransformer` uses a large language model to translate a query to a target language that is supported by the embedding model used to generate the document embeddings. If the query is already in the target language, it is returned unchanged. If the language of the query is unknown, it is also returned unchanged. This transformer is useful when the embedding model is trained on a specific language and the user query is in a different language. [source,java] ---- Query query = new Query("Hvad er Danmarks hovedstad?"); QueryTransformer queryTransformer = TranslationQueryTransformer.builder() .chatClientBuilder(chatClientBuilder) .targetLanguage("english") .build(); Query transformedQuery = queryTransformer.transform(query); ---- The prompt used by this component can be customized via the `promptTemplate()` method available in the builder. ==== Query Expansion A component for expanding the input query into a list of queries, addressing challenges such as poorly formed queries by providing alternative query formulations, or by breaking down complex problems into simpler sub-queries. ===== MultiQueryExpander A `MultiQueryExpander` uses a large language model to expand a query into multiple semantically diverse variations to capture different perspectives, useful for retrieving additional contextual information and increasing the chances of finding relevant results. [source,java] ---- MultiQueryExpander queryExpander = MultiQueryExpander.builder() .chatClientBuilder(chatClientBuilder) .numberOfQueries(3) .build(); List queries = queryExpander.expand(new Query("How to run a Spring Boot app?")); ---- By default, the `MultiQueryExpander` includes the original query in the list of expanded queries. You can disable this behavior via the `includeOriginal` method in the builder. [source,java] ---- MultiQueryExpander queryExpander = MultiQueryExpander.builder() .chatClientBuilder(chatClientBuilder) .includeOriginal(false) .build(); ---- The prompt used by this component can be customized via the `promptTemplate()` method available in the builder. === Retrieval Retrieval modules are responsible for querying data systems like vector store and retrieving the most relevant documents. ==== Document Search Component responsible for retrieving `Documents` from an underlying data source, such as a search engine, a vector store, a database, or a knowledge graph. ===== VectorStoreDocumentRetriever A `VectorStoreDocumentRetriever` retrieves documents from a vector store that are semantically similar to the input query. It supports filtering based on metadata, similarity threshold, and top-k results. [source,java] ---- DocumentRetriever retriever = VectorStoreDocumentRetriever.builder() .vectorStore(vectorStore) .similarityThreshold(0.73) .topK(5) .filterExpression(new FilterExpressionBuilder() .eq("genre", "fairytale") .build()) .build(); List documents = retriever.retrieve(new Query("What is the main character of the story?")); ---- The filter expression can be static or dynamic. For dynamic filter expressions, you can pass a `Supplier`. [source,java] ---- DocumentRetriever retriever = VectorStoreDocumentRetriever.builder() .vectorStore(vectorStore) .filterExpression(() -> new FilterExpressionBuilder() .eq("tenant", TenantContextHolder.getTenantIdentifier()) .build()) .build(); List documents = retriever.retrieve(new Query("What are the KPIs for the next semester?")); ---- You can also provide a request-specific filter expression via the `Query` API, using the `FILTER_EXPRESSION` parameter. If both the request-specific and the retriever-specific filter expressions are provided, the request-specific filter expression takes precedence. [source,java] ---- Query query = Query.builder() .text("Who is Anacletus?") .context(Map.of(VectorStoreDocumentRetriever.FILTER_EXPRESSION, "location == 'Whispering Woods'")) .build(); List retrievedDocuments = documentRetriever.retrieve(query); ---- ==== Document Join A component for combining documents retrieved based on multiple queries and from multiple data sources into a single collection of documents. As part of the joining process, it can also handle duplicate documents and reciprocal ranking strategies. ===== ConcatenationDocumentJoiner A `ConcatenationDocumentJoiner` combines documents retrieved based on multiple queries and from multiple data sources by concatenating them into a single collection of documents. In case of duplicate documents, the first occurrence is kept. The score of each document is kept as is. [source,java] ---- Map>> documentsForQuery = ... DocumentJoiner documentJoiner = new ConcatenationDocumentJoiner(); List documents = documentJoiner.join(documentsForQuery); ---- === Post-Retrieval Post-Retrieval modules are responsible for processing the retrieved documents to achieve the best possible generation results. ==== Document Post-Processing A component for post-processing retrieved documents based on a query, addressing challenges such as _lost-in-the-middle_, context length restrictions from the model, and the need to reduce noise and redundancy in the retrieved information. For example, it could rank 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. === Generation Generation modules are responsible for generating the final response based on the user query and retrieved documents. ==== Query Augmentation A component for augmenting an input query with additional data, useful to provide a large language model with the necessary context to answer the user query. ===== ContextualQueryAugmenter The `ContextualQueryAugmenter` augments the user query with contextual data from the content of the provided documents. [source,java] ---- QueryAugmenter queryAugmenter = ContextualQueryAugmenter.builder().build(); ---- By default, the `ContextualQueryAugmenter` does not allow the retrieved context to be empty. When that happens, it instructs the model not to answer the user query. You can enable the `allowEmptyContext` option to allow the model to generate a response even when the retrieved context is empty. [source,java] ---- QueryAugmenter queryAugmenter = ContextualQueryAugmenter.builder() .allowEmptyContext(true) .build(); ---- The prompts used by this component can be customized via the `promptTemplate()` and `emptyContextPromptTemplate()` methods available in the builder. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/speech.adoc ================================================ [[Speech]] = Speech Model API [NOTE] ==== This page has been superseded by the new Text-to-Speech (TTS) documentation.

The Spring AI `Structured Output Converters` help to convert the LLM output into a structured format. As shown in the following diagram, this approach operates around the LLM text completion endpoint: image::structured-output-architecture.jpg[Structured Output Converter Architecture, width=900, align="center"] Generating 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. Before 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. NOTE: 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. After 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. TIP: The `StructuredOutputConverter` is a best effort to convert the model output into a structured output. The AI Model is not guaranteed to return the structured output as requested. The model may not understand the prompt or be unable to generate the structured output as requested. Consider implementing a validation mechanism to ensure the model output is as expected. TIP: The `StructuredOutputConverter` is not used for LLM xref:api/tools.adoc[Tool Calling], as this feature inherently provides structured outputs by default. == Structured Output API The `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. The interface definition is: [source,java] ---- public interface StructuredOutputConverter extends Converter, FormatProvider { } ---- It combines the Spring https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/convert/converter/Converter.html[Converter] interface and the `FormatProvider` interface [source,java] ---- public interface FormatProvider { String getFormat(); } ---- The following diagram shows the data flow when using the structured output API. image::structured-output-api.jpg[Structured Output API, width=900, align="center"] The `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: ---- Your response should be in JSON format. The data structure for the JSON should match this Java class: java.util.HashMap Do not include any explanations, only provide a RFC8259 compliant JSON response following this format without deviation. ---- The format instructions are most often appended to the end of the user input using the xref:api/prompt.adoc#_prompttemplate[PromptTemplate] like this: [source,java] ---- StructuredOutputConverter outputConverter = ... String userInputTemplate = """ ... user text input .... {format} """; // user input with a "format" placeholder. Prompt prompt = new Prompt( PromptTemplate.builder() .template(this.userInputTemplate) .variables(Map.of(..., "format", this.outputConverter.getFormat())) // replace the "format" placeholder with the converter's format. .build().createMessage() ); ---- The Converter is responsible to transform output text from the model into instances of the specified type `T`. === Available Converters Currently, Spring AI provides `AbstractConversionServiceOutputConverter`, `AbstractMessageOutputConverter`, `BeanOutputConverter`, `MapOutputConverter` and `ListOutputConverter` implementations: image::structured-output-hierarchy4.jpg[Structured Output Class Hierarchy, width=900, align="center"] * `AbstractConversionServiceOutputConverter` - 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. * `AbstractMessageOutputConverter` - 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. * `BeanOutputConverter` - 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. * `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` instance. * `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`. == Using Converters The following sections provide guides how to use the available converters to generate structured outputs. === Bean Output Converter The following example shows how to use `BeanOutputConverter` to generate the filmography for an actor. The target record representing actor's filmography: [source,java] ---- record ActorsFilms(String actor, List movies) { } ---- Here is how to apply the BeanOutputConverter using the high-level, fluent `ChatClient` API: [source,java] ---- ActorsFilms actorsFilms = ChatClient.create(chatModel).prompt() .user(u -> u.text("Generate the filmography of 5 movies for {actor}.") .param("actor", "Tom Hanks")) .call() .entity(ActorsFilms.class); ---- or using the low-level `ChatModel` API directly: [source,java] ---- BeanOutputConverter beanOutputConverter = new BeanOutputConverter<>(ActorsFilms.class); String format = this.beanOutputConverter.getFormat(); String actor = "Tom Hanks"; String template = """ Generate the filmography of 5 movies for {actor}. {format} """; Generation generation = chatModel.call( PromptTemplate.builder().template(this.template).variables(Map.of("actor", this.actor, "format", this.format)).build().create()).getResult(); ActorsFilms actorsFilms = this.beanOutputConverter.convert(this.generation.getOutput().getText()); ---- === Property Ordering in Generated Schema The `BeanOutputConverter` supports custom property ordering in the generated JSON schema through the `@JsonPropertyOrder` annotation. This 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. For example, to ensure specific ordering of properties in the `ActorsFilms` record: [source,java] ---- @JsonPropertyOrder({"actor", "movies"}) record ActorsFilms(String actor, List movies) {} ---- This annotation works with both records and regular Java classes. ==== Generic Bean Types Use the `ParameterizedTypeReference` constructor to specify a more complex target class structure. For example, to represent a list of actors and their filmographies: [source,java] ---- List actorsFilms = ChatClient.create(chatModel).prompt() .user("Generate the filmography of 5 movies for Tom Hanks and Bill Murray.") .call() .entity(new ParameterizedTypeReference>() {}); ---- or using the low-level `ChatModel` API directly: [source,java] ---- BeanOutputConverter> outputConverter = new BeanOutputConverter<>( new ParameterizedTypeReference>() { }); String format = this.outputConverter.getFormat(); String template = """ Generate the filmography of 5 movies for Tom Hanks and Bill Murray. {format} """; Prompt prompt = PromptTemplate.builder().template(this.template).variables(Map.of("format", this.format)).build().create(); Generation generation = chatModel.call(this.prompt).getResult(); List actorsFilms = this.outputConverter.convert(this.generation.getOutput().getText()); ---- === Map Output Converter The following snippet shows how to use `MapOutputConverter` to convert the model output to a list of numbers in a map. [source,java] ---- Map result = ChatClient.create(chatModel).prompt() .user(u -> u.text("Provide me a List of {subject}") .param("subject", "an array of numbers from 1 to 9 under they key name 'numbers'")) .call() .entity(new ParameterizedTypeReference>() {}); ---- or using the low-level `ChatModel` API directly: [source,java] ---- MapOutputConverter mapOutputConverter = new MapOutputConverter(); String format = this.mapOutputConverter.getFormat(); String template = """ Provide me a List of {subject} {format} """; Prompt prompt = PromptTemplate.builder().template(this.template) .variables(Map.of("subject", "an array of numbers from 1 to 9 under they key name 'numbers'", "format", this.format)).build().create(); Generation generation = chatModel.call(this.prompt).getResult(); Map result = this.mapOutputConverter.convert(this.generation.getOutput().getText()); ---- === List Output Converter The following snippet shows how to use `ListOutputConverter` to convert the model output into a list of ice cream flavors. [source,java] ---- List flavors = ChatClient.create(chatModel).prompt() .user(u -> u.text("List five {subject}") .param("subject", "ice cream flavors")) .call() .entity(new ListOutputConverter(new DefaultConversionService())); ---- or using the low-level `ChatModel API` directly: [source,java] ---- ListOutputConverter listOutputConverter = new ListOutputConverter(new DefaultConversionService()); String format = this.listOutputConverter.getFormat(); String template = """ List five {subject} {format} """; Prompt prompt = PromptTemplate.builder().template(this.template).variables(Map.of("subject", "ice cream flavors", "format", this.format)).build().create(); Generation generation = this.chatModel.call(this.prompt).getResult(); List list = this.listOutputConverter.convert(this.generation.getOutput().getText()); ---- == Native Structured Output Many 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. When 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: * **Higher reliability**: The model guarantees output conforming to the schema * **Cleaner prompts**: No need to append format instructions * **Better performance**: Models can optimize for structured output internally === Using Native Structured Output To enable native structured output, use the `AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT` parameter: [source,java] ---- ActorsFilms actorsFilms = ChatClient.create(chatModel).prompt() .advisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT) .user("Generate the filmography for a random actor.") .call() .entity(ActorsFilms.class); ---- You can also set this globally using `defaultAdvisors()` on the `ChatClient.Builder`: [source,java] ---- @Bean ChatClient chatClient(ChatClient.Builder builder) { return builder .defaultAdvisors(AdvisorParams.ENABLE_NATIVE_STRUCTURED_OUTPUT) .build(); } ---- === Supported Models for Native Structured Output The following models currently support native structured output: * **OpenAI**: GPT-4o and later models with JSON Schema support * **Anthropic**: Claude 3.5 Sonnet and later models * **Google GenAI**: Gemini 1.5 Pro and later models * **Mistral AI**: Mistral Small and later models with JSON Schema support NOTE: 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). === Built-in JSON mode Some AI Models provide dedicated configuration options to generate structured (usually JSON) output. * 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). * 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. * 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`. * 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. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/testcontainers.adoc ================================================ [[testcontainers]] = Testcontainers Spring AI provides Spring Boot auto-configuration for establishing a connection to a model service or vector store running via Testcontainers. To enable it, add the following dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-spring-boot-testcontainers ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-spring-boot-testcontainers' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. == Service Connections The following service connection factories are provided in the `spring-ai-spring-boot-testcontainers` module: [cols="|,|"] |==== | Connection Details | Matched on | `AwsOpenSearchConnectionDetails` | Containers of type `LocalStackContainer` | `ChromaConnectionDetails` | Containers of type `ChromaDBContainer` | `McpSseClientConnectionDetails` | Containers of type `DockerMcpGatewayContainer` | `MilvusServiceClientConnectionDetails` | Containers of type `MilvusContainer` | `OllamaConnectionDetails` | Containers of type `OllamaContainer` | `OpenSearchConnectionDetails` | Containers of type `OpenSearchContainer` | `QdrantConnectionDetails` | Containers of type `QdrantContainer` | `TypesenseConnectionDetails` | Containers of type `TypesenseContainer` | `WeaviateConnectionDetails` | Containers of type `WeaviateContainer` |==== More service connections are provided by the spring boot module `spring-boot-testcontainers`. Refer to the https://docs.spring.io/spring-boot/reference/testing/testcontainers.html#testing.testcontainers.service-connections[Testcontainers Service Connections] documentation page for the full list. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/testing.adoc ================================================ = Evaluation Testing Testing AI applications requires evaluating the generated content to ensure the AI model has not produced a hallucinated response. One 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. The Spring AI interface for evaluating responses is `Evaluator`, defined as: [source,java] ---- @FunctionalInterface public interface Evaluator { EvaluationResponse evaluate(EvaluationRequest evaluationRequest); } ---- The input to the evaluation is the `EvaluationRequest` defined as [source,java] ---- public class EvaluationRequest { private final String userText; private final List dataList; private final String responseContent; public EvaluationRequest(String userText, List dataList, String responseContent) { this.userText = userText; this.dataList = dataList; this.responseContent = responseContent; } ... } ---- * `userText`: The raw input from the user as a `String` * `dataList`: Contextual data, such as from Retrieval Augmented Generation, appended to the raw input. * `responseContent`: The AI model's response content as a `String` == Relevancy Evaluator The `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. The 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. This is the default prompt template used by the `RelevancyEvaluator`: [source,text] ---- Your task is to evaluate if the response for the query is in line with the context information provided. You have two options to answer. Either YES or NO. Answer YES, if the response for the query is in line with context information otherwise NO. Query: {query} Response: {response} Context: {context} Answer: ---- NOTE: 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. == Usage in Integration Tests Here is an example of usage of the `RelevancyEvaluator` in an integration test, validating the result of a RAG flow using the `RetrievalAugmentationAdvisor`: [source,java] ---- @Test void evaluateRelevancy() { String question = "Where does the adventure of Anacletus and Birba take place?"; RetrievalAugmentationAdvisor ragAdvisor = RetrievalAugmentationAdvisor.builder() .documentRetriever(VectorStoreDocumentRetriever.builder() .vectorStore(pgVectorStore) .build()) .build(); ChatResponse chatResponse = ChatClient.builder(chatModel).build() .prompt(question) .advisors(ragAdvisor) .call() .chatResponse(); EvaluationRequest evaluationRequest = new EvaluationRequest( // The original user question question, // The retrieved context from the RAG flow chatResponse.getMetadata().get(RetrievalAugmentationAdvisor.DOCUMENT_CONTEXT), // The AI model's response chatResponse.getResult().getOutput().getText() ); RelevancyEvaluator evaluator = new RelevancyEvaluator(ChatClient.builder(chatModel)); EvaluationResponse evaluationResponse = evaluator.evaluate(evaluationRequest); assertThat(evaluationResponse.isPass()).isTrue(); } ---- You 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]). === Custom Template The `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. The 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: * a `query` placeholder to receive the user question. * a `response` placeholder to receive the AI model's response. * a `context` placeholder to receive the context information. == FactCheckingEvaluator The 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). The '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. === Usage The FactCheckingEvaluator constructor takes a ChatClient.Builder as a parameter: [source,java] ---- public FactCheckingEvaluator(ChatClient.Builder chatClientBuilder) { this.chatClientBuilder = chatClientBuilder; } ---- The evaluator uses the following prompt template for fact-checking: [source,text] ---- Document: {document} Claim: {claim} ---- Where `+{document}+` is the context information, and `+{claim}+` is the AI model's response to be evaluated. === Example Here's an example of how to use the FactCheckingEvaluator with an Ollama-based ChatModel, specifically the Bespoke-Minicheck model: [source,java] ---- @Test void testFactChecking() { // Set up the Ollama API OllamaApi ollamaApi = new OllamaApi("http://localhost:11434"); ChatModel chatModel = new OllamaChatModel(ollamaApi, OllamaChatOptions.builder().model(BESPOKE_MINICHECK).numPredict(2).temperature(0.0d).build()) // Create the FactCheckingEvaluator var factCheckingEvaluator = new FactCheckingEvaluator(ChatClient.builder(chatModel)); // Example context and claim String context = "The Earth is the third planet from the Sun and the only astronomical object known to harbor life."; String claim = "The Earth is the fourth planet from the Sun."; // Create an EvaluationRequest EvaluationRequest evaluationRequest = new EvaluationRequest(context, Collections.emptyList(), claim); // Perform the evaluation EvaluationResponse evaluationResponse = factCheckingEvaluator.evaluate(evaluationRequest); assertFalse(evaluationResponse.isPass(), "The claim should not be supported by the context"); } ---- ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/tools-migration.adoc ================================================ = Migrating from FunctionCallback to ToolCallback API This 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. == Overview of Changes These 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. == Key Changes 1. `FunctionCallback` → `ToolCallback` 2. `FunctionCallback.builder().function()` → `FunctionToolCallback.builder()` 3. `FunctionCallback.builder().method()` → `MethodToolCallback.builder()` 4. `FunctionCallingOptions` → `ToolCallingChatOptions` 5. `ChatClient.builder().defaultFunctions()` → `ChatClient.builder().defaultTools()` 6. `ChatClient.functions()` → `ChatClient.tools()` 7. `FunctionCallingOptions.builder().functions()` → `ToolCallingChatOptions.builder().toolNames()` 8. `FunctionCallingOptions.builder().functionCallbacks()` → `ToolCallingChatOptions.builder().toolCallbacks()` == Migration Examples === 1. Basic Function Callback Before: [source,java] ---- FunctionCallback.builder() .function("getCurrentWeather", new MockWeatherService()) .description("Get the weather in location") .inputType(MockWeatherService.Request.class) .build() ---- After: [source,java] ---- FunctionToolCallback.builder("getCurrentWeather", new MockWeatherService()) .description("Get the weather in location") .inputType(MockWeatherService.Request.class) .build() ---- === 2. ChatClient Usage Before: [source,java] ---- String response = ChatClient.create(chatModel) .prompt() .user("What's the weather like in San Francisco?") .functions(FunctionCallback.builder() .function("getCurrentWeather", new MockWeatherService()) .description("Get the weather in location") .inputType(MockWeatherService.Request.class) .build()) .call() .content(); ---- After: [source,java] ---- String response = ChatClient.create(chatModel) .prompt() .user("What's the weather like in San Francisco?") .tools(FunctionToolCallback.builder("getCurrentWeather", new MockWeatherService()) .description("Get the weather in location") .inputType(MockWeatherService.Request.class) .build()) .call() .content(); ---- === 3. Method-Based Function Callbacks Before: [source,java] ---- FunctionCallback.builder() .method("getWeatherInLocation", String.class, Unit.class) .description("Get the weather in location") .targetClass(TestFunctionClass.class) .build() ---- After: [source,java] ---- var toolMethod = ReflectionUtils.findMethod(TestFunctionClass.class, "getWeatherInLocation"); MethodToolCallback.builder() .toolDefinition(ToolDefinition.builder(toolMethod) .description("Get the weather in location") .build()) .toolMethod(toolMethod) .build() ---- Or with the declarative approach: [source,java] ---- class WeatherTools { @Tool(description = "Get the weather in location") public void getWeatherInLocation(String location, Unit unit) { // ... } } ---- And you can use the same `ChatClient#tools()` API to register method-based tool callbacks: [source,java] ---- String response = ChatClient.create(chatModel) .prompt() .user("What's the weather like in San Francisco?") .tools(MethodToolCallback.builder() .toolDefinition(ToolDefinition.builder(toolMethod) .description("Get the weather in location") .build()) .toolMethod(toolMethod) .build()) .call() .content(); ---- Or with the declarative approach: [source,java] ---- String response = ChatClient.create(chatModel) .prompt() .user("What's the weather like in San Francisco?") .tools(new WeatherTools()) .call() .content(); ---- === 4. Options Configuration Before: [source,java] ---- FunctionCallingOptions.builder() .model(modelName) .function("weatherFunction") .build() ---- After: [source,java] ---- ToolCallingChatOptions.builder() .model(modelName) .toolNames("weatherFunction") .build() ---- === 5. Default Functions in ChatClient Builder Before: [source,java] ---- ChatClient.builder(chatModel) .defaultFunctions(FunctionCallback.builder() .function("getCurrentWeather", new MockWeatherService()) .description("Get the weather in location") .inputType(MockWeatherService.Request.class) .build()) .build() ---- After: [source,java] ---- ChatClient.builder(chatModel) .defaultTools(FunctionToolCallback.builder("getCurrentWeather", new MockWeatherService()) .description("Get the weather in location") .inputType(MockWeatherService.Request.class) .build()) .build() ---- === 6. Spring Bean Configuration Before: [source,java] ---- @Bean public FunctionCallback weatherFunctionInfo() { return FunctionCallback.builder() .function("WeatherInfo", new MockWeatherService()) .description("Get the current weather") .inputType(MockWeatherService.Request.class) .build(); } ---- After: [source,java] ---- @Bean public ToolCallback weatherFunctionInfo() { return FunctionToolCallback.builder("WeatherInfo", new MockWeatherService()) .description("Get the current weather") .inputType(MockWeatherService.Request.class) .build(); } ---- == Breaking Changes 1. The `method()` configuration in function callbacks has been replaced with a more explicit method tool configuration using `ToolDefinition` and `MethodToolCallback`. 2. 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. 3. For non-static methods, you must now provide both the method and the target object: [source,java] ---- MethodToolCallback.builder() .toolDefinition(ToolDefinition.builder(toolMethod) .description("Description") .build()) .toolMethod(toolMethod) .toolObject(targetObject) .build() ---- == Deprecated Methods The following methods are deprecated and will be removed in a future release: - `ChatClient.Builder.defaultFunctions(String...)` - `ChatClient.Builder.defaultFunctions(FunctionCallback...)` - `ChatClient.RequestSpec.functions()` Use their `tools` counterparts instead. == Declarative Specification with @Tool Now you can use the method-level annotation (`@Tool`) to register tools with Spring AI: [source,java] ---- class Home { @Tool(description = "Turn light On or Off in a room.") void turnLight(String roomName, boolean on) { // ... logger.info("Turn light in room: {} to: {}", roomName, on); } } String response = ChatClient.create(this.chatModel).prompt() .user("Turn the light in the living room On.") .tools(new Home()) .call() .content(); ---- == Additional Notes 1. The new API provides better separation between tool definition and implementation. 2. Tool definitions can be reused across different implementations. 3. The builder pattern has been simplified for common use cases. 4. Better support for method-based tools with improved error handling. == Timeline The 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. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/tools.adoc ================================================ [[Tools]] = Tool Calling _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. Tools are mainly used for: * **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. * **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. Even 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. Spring 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. NOTE: Check the xref:api/chat/comparison.adoc[Chat Model Comparisons] to see which AI models support tool calling invocation. TIP: Follow the guide to migrate from the deprecated xref:api/tools-migration.adoc[FunctionCallback to ToolCallback API]. == Quick Start Let'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. === Information Retrieval AI 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. Let'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. [source,java] ---- import java.time.LocalDateTime; import org.springframework.ai.tool.annotation.Tool; import org.springframework.context.i18n.LocaleContextHolder; class DateTimeTools { @Tool(description = "Get the current date and time in the user's timezone") String getCurrentDateTime() { return LocalDateTime.now().atZone(LocaleContextHolder.getTimeZone().toZoneId()).toString(); } } ---- Next, 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. [source,java] ---- ChatModel chatModel = ... String response = ChatClient.create(chatModel) .prompt("What day is tomorrow?") .tools(new DateTimeTools()) .call() .content(); System.out.println(response); ---- The output will be something like: [source] ---- Tomorrow is 2015-10-21. ---- You can retry asking the same question again. This time, don't provide the tool to the model. The output will be something like: [source] ---- I 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. ---- Without 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. === Taking Actions AI 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. In 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. We'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. [source,java] ---- import java.time.LocalDateTime; import java.time.format.DateTimeFormatter; import org.springframework.ai.tool.annotation.Tool; import org.springframework.context.i18n.LocaleContextHolder; class DateTimeTools { @Tool(description = "Get the current date and time in the user's timezone") String getCurrentDateTime() { return LocalDateTime.now().atZone(LocaleContextHolder.getTimeZone().toZoneId()).toString(); } @Tool(description = "Set a user alarm for the given time, provided in ISO-8601 format") void setAlarm(String time) { LocalDateTime alarmTime = LocalDateTime.parse(time, DateTimeFormatter.ISO_DATE_TIME); System.out.println("Alarm set for " + alarmTime); } } ---- Next, 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. [source,java] ---- ChatModel chatModel = ... String response = ChatClient.create(chatModel) .prompt("Can you set an alarm 10 minutes from now?") .tools(new DateTimeTools()) .call() .content(); System.out.println(response); ---- In the application logs, you can check the alarm has been set at the correct time. == Overview Spring 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. image::tools/tool-calling-01.jpg[The main sequence of actions for tool calling, width=700, align="center"] 1. 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. 2. 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. 3. The application is responsible for using the tool name to identify and execute the tool with the provided input parameters. 4. The result of the tool call is processed by the application. 5. The application sends the tool call result back to the model. 6. The model generates the final response using the tool call result as additional context. Tools 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. `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. Both `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. Besides passing the `ToolCallback` objects directly, you can also pass a list of tool names, that will be resolved dynamically using the `ToolCallbackResolver` interface. The 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. == Methods as Tools Spring AI provides built-in support for specifying tools (i.e. `ToolCallback`(s)) from methods in two ways: - declaratively, using the `@Tool` annotation - programmatically, using the low-level `MethodToolCallback` implementation. === Declarative Specification: `@Tool` You can turn a method into a tool by annotating it with `@Tool`. [source,java] ---- class DateTimeTools { @Tool(description = "Get the current date and time in the user's timezone") String getCurrentDateTime() { return LocalDateTime.now().atZone(LocaleContextHolder.getTimeZone().toZoneId()).toString(); } } ---- The `@Tool` annotation allows you to provide key information about the tool: - `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. - `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. - `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. - `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. The 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). NOTE: 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)`. You 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. NOTE: Some types are not supported. See xref:_method_tool_limitations[] for more details. Spring 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. [source,java] ---- import java.time.LocalDateTime; import java.time.format.DateTimeFormatter; import org.springframework.ai.tool.annotation.Tool; import org.springframework.ai.tool.annotation.ToolParam; class DateTimeTools { @Tool(description = "Set a user alarm for the given time") void setAlarm(@ToolParam(description = "Time in ISO-8601 format") String time) { LocalDateTime alarmTime = LocalDateTime.parse(time, DateTimeFormatter.ISO_DATE_TIME); System.out.println("Alarm set for " + alarmTime); } } ---- The `@ToolParam` annotation allows you to provide key information about a tool parameter: - `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. - `required`: Whether the parameter is required or optional. By default, all parameters are considered required. If a parameter is annotated as `@Nullable`, it will be considered optional unless explicitly marked as required using the `@ToolParam` annotation. Besides the `@ToolParam` annotation, you can also use the `@Schema` annotation from Swagger or `@JsonProperty` from Jackson. See xref:_json_schema[] for more details. ==== Adding Tools to `ChatClient` When 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. [source,java] ---- ChatClient.create(chatModel) .prompt("What day is tomorrow?") .tools(new DateTimeTools()) .call() .content(); ---- Under 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. [source,java] ---- ToolCallback[] dateTimeTools = ToolCallbacks.from(new DateTimeTools()); ---- ==== Adding Default Tools to `ChatClient` When using the declarative specification approach, you can add default tools to a `ChatClient.Builder` by passing the tool class instance to the `defaultTools()` method. If both default and runtime tools are provided, the runtime tools will completely override the default tools. WARNING: 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.

Required. - `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. - `toolMethod`: The `Method` instance that represents the tool method. Required. - `toolObject`: The object instance that contains the tool method. If the method is static, you can omit this parameter. - `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`).

Functional types are supported using the function-based tool specification approach. See xref:_functions_as_tools[] for more details. == Functions as Tools Spring AI provides built-in support for specifying tools from functions, either programmatically using the low-level `FunctionToolCallback` implementation or dynamically as `@Bean`(s) resolved at runtime. === Programmatic Specification: `FunctionToolCallback` You can turn a functional type (`Function`, `Supplier`, `Consumer`, or `BiFunction`) into a tool by building a `FunctionToolCallback` programmatically. [source,java] ---- public class WeatherService implements Function { public WeatherResponse apply(WeatherRequest request) { return new WeatherResponse(30.0, Unit.C); } } public enum Unit { C, F } public record WeatherRequest(String location, Unit unit) {} public record WeatherResponse(double temp, Unit unit) {} ---- The `FunctionToolCallback.Builder` allows you to build a `FunctionToolCallback` instance and provide key information about the tool: - `name`: The name of the tool.

Primitive types and collections are supported using the method-based tool specification approach. See xref:_methods_as_tools[] for more details. == Tool Specification In 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. === Tool Callback The `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). The interface provides the following methods: [source,java] ---- public interface ToolCallback { /** * Definition used by the AI model to determine when and how to call the tool. */ ToolDefinition getToolDefinition(); /** * Metadata providing additional information on how to handle the tool. */ ToolMetadata getToolMetadata(); /** * Execute tool with the given input and return the result to send back to the AI model. */ String call(String toolInput); /** * Execute tool with the given input and context, and return the result to send back to the AI model. */ String call(String toolInput, ToolContext tooContext); } ---- Spring AI provides built-in implementations for tool methods (`MethodToolCallback`) and tool functions (`FunctionToolCallback`). === Tool Definition The `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. The interface provides the following methods: [source,java] ---- public interface ToolDefinition { /** * The tool name. Unique within the tool set provided to a model. */ String name(); /** * The tool description, used by the AI model to determine what the tool does. */ String description(); /** * The schema of the parameters used to call the tool. */ String inputSchema(); } ---- NOTE: See xref:_json_schema[] for more details on the input schema. The `ToolDefinition.Builder` lets you build a `ToolDefinition` instance using the default implementation (`DefaultToolDefinition`). [source,java] ---- ToolDefinition toolDefinition = ToolDefinition.builder() .name("currentWeather") .description("Get the weather in location") .inputSchema(""" { "type": "object", "properties": { "location": { "type": "string" }, "unit": { "type": "string", "enum": ["C", "F"] } }, "required": ["location", "unit"] } """) .build(); ---- ==== Method Tool Definition When 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. [source,java] ---- Method method = ReflectionUtils.findMethod(DateTimeTools.class, "getCurrentDateTime"); ToolDefinition toolDefinition = ToolDefinitions.from(method); ---- The `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. NOTE: See xref:_methods_as_tools[] for more details. If you'd rather provide some or all of the attributes explicitly, you can use the `ToolDefinition.Builder` to build a custom `ToolDefinition` instance. [source,java] ---- Method method = ReflectionUtils.findMethod(DateTimeTools.class, "getCurrentDateTime"); ToolDefinition toolDefinition = ToolDefinitions.builder(method) .name("currentDateTime") .description("Get the current date and time in the user's timezone") .inputSchema(JsonSchemaGenerator.generateForMethodInput(method)) .build(); ---- ==== Function Tool Definition When 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. === JSON Schema When 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`. NOTE: See xref:_tool_definition[] for more details on the `ToolDefinition` and how to pass the input schema to it. The `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. This section describes two main options you can customize when generating the JSON schema for the input parameters of a tool: description and required status. ==== Description Besides 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: - `@ToolParam(description = "...")` from Spring AI - `@JsonClassDescription(description = "...")` from Jackson - `@JsonPropertyDescription(description = "...")` from Jackson - `@Schema(description = "...")` from Swagger. This approach works for both methods and functions, and you can use it recursively for nested types. [source,java] ---- import java.time.LocalDateTime; import java.time.format.DateTimeFormatter; import org.springframework.ai.tool.annotation.Tool; import org.springframework.ai.tool.annotation.ToolParam; import org.springframework.context.i18n.LocaleContextHolder; class DateTimeTools { @Tool(description = "Set a user alarm for the given time") void setAlarm(@ToolParam(description = "Time in ISO-8601 format") String time) { LocalDateTime alarmTime = LocalDateTime.parse(time, DateTimeFormatter.ISO_DATE_TIME); System.out.println("Alarm set for " + alarmTime); } } ---- ==== Required/Optional By 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: - `@ToolParam(required = false)` from Spring AI - `@JsonProperty(required = false)` from Jackson - `@Schema(required = false)` from Swagger - `@Nullable` from Spring Framework. This approach works for both methods and functions, and you can use it recursively for nested types. [source,java] ---- class CustomerTools { @Tool(description = "Update customer information") void updateCustomerInfo(Long id, String name, @ToolParam(required = false) String email) { System.out.println("Updated info for customer with id: " + id); } } ---- WARNING: 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. === Result Conversion The 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. The interface provides the following method: [source,java] ---- @FunctionalInterface public interface ToolCallResultConverter { /** * Given an Object returned by a tool, convert it to a String compatible with the * given class type. */ String convert(@Nullable Object result, @Nullable Type returnType); } ---- The 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. Spring AI relies on the `ToolCallResultConverter` in both method and function tools. ==== Method Tool Call Result Conversion When 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. [source,java] ---- class CustomerTools { @Tool(description = "Retrieve customer information", resultConverter = CustomToolCallResultConverter.class) Customer getCustomerInfo(Long id) { return customerRepository.findById(id); } } ---- If using the programmatic approach, you can provide a custom `ToolCallResultConverter` to use for the tool by setting the `resultConverter()` attribute of the `MethodToolCallback.Builder`. See xref:_methods_as_tools[] for more details. ==== Function Tool Call Result Conversion When 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`. See xref:_functions_as_tools[] for more details. === Tool Context Spring 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. image::tools/tool-context.jpg[Providing additional contextual info to tools, width=700, align="center"] [source,java] ---- class CustomerTools { @Tool(description = "Retrieve customer information") Customer getCustomerInfo(Long id, ToolContext toolContext) { return customerRepository.findById(id, toolContext.getContext().get("tenantId")); } } ---- The `ToolContext` is populated with the data provided by the user when invoking `ChatClient`. [source,java] ---- ChatModel chatModel = ... String response = ChatClient.create(chatModel) .prompt("Tell me more about the customer with ID 42") .tools(new CustomerTools()) .toolContext(Map.of("tenantId", "acme")) .call() .content(); System.out.println(response); ---- NOTE: None of the data provided in the `ToolContext` is sent to the AI model. Similarly, you can define tool context data when invoking the `ChatModel` directly. [source,java] ---- ChatModel chatModel = ... ToolCallback[] customerTools = ToolCallbacks.from(new CustomerTools()); ChatOptions chatOptions = ToolCallingChatOptions.builder() .toolCallbacks(customerTools) .toolContext(Map.of("tenantId", "acme")) .build(); Prompt prompt = new Prompt("Tell me more about the customer with ID 42", chatOptions); chatModel.call(prompt); ---- If 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, where the runtime options take precedence over the default options. === Return Direct By 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. There 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. Each `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. The `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. NOTE: 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. image::tools/return-direct.jpg[Returning tool call results directly to the caller, width=700, align="center"] 1. 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`. 2. 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. 3. The application is responsible for using the tool name to identify and execute the tool with the provided input parameters. 4. The result of the tool call is processed by the application. 5. The application sends the tool call result directly to the caller, instead of sending it back to the model. ==== Method Return Direct When 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`. [source,java] ---- class CustomerTools { @Tool(description = "Retrieve customer information", returnDirect = true) Customer getCustomerInfo(Long id) { return customerRepository.findById(id); } } ---- If using the programmatic approach, you can set the `returnDirect` attribute via the `ToolMetadata` interface and pass it to the `MethodToolCallback.Builder`. [source,java] ---- ToolMetadata toolMetadata = ToolMetadata.builder() .returnDirect(true) .build(); ---- See xref:_methods_as_tools[] for more details. ==== Function Return Direct When 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`. [source,java] ---- ToolMetadata toolMetadata = ToolMetadata.builder() .returnDirect(true) .build(); ---- See xref:_functions_as_tools[] for more details. == Tool Execution The 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. [source,java] ---- public interface ToolCallingManager { /** * Resolve the tool definitions from the model's tool calling options. */ List resolveToolDefinitions(ToolCallingChatOptions chatOptions); /** * Execute the tool calls requested by the model. */ ToolExecutionResult executeToolCalls(Prompt prompt, ChatResponse chatResponse); } ---- If 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. [source,java] ---- @Bean ToolCallingManager toolCallingManager() { return ToolCallingManager.builder().build(); } ---- By 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. === Framework-Controlled Tool Execution When 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`. image::tools/framework-manager.jpg[Framework-controlled tool execution lifecycle, width=700, align="center"] 1. 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. 2. 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. 3. The `ChatModel` sends the tool call request to the `ToolCallingManager` API. 4. The `ToolCallingManager` is responsible for identifying the tool to call and executing it with the provided input parameters. 5. The result of the tool call is returned to the `ToolCallingManager`. 6. The `ToolCallingManager` returns the tool execution result back to the `ChatModel`. 7. The `ChatModel` sends the tool execution result back to the AI model (`ToolResponseMessage`). 8. 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`. WARNING: 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. The 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. [source,java] ---- public class DefaultToolExecutionEligibilityPredicate implements ToolExecutionEligibilityPredicate { @Override public boolean test(ChatOptions promptOptions, ChatResponse chatResponse) { return ToolCallingChatOptions.isInternalToolExecutionEnabled(promptOptions) && chatResponse != null && chatResponse.hasToolCalls(); } } ---- You can provide your custom implementation of `ToolExecutionEligibilityPredicate` when creating the `ChatModel` bean. === Advisor-Controlled Tool Execution with ToolCallAdvisor As 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: * **Observability**: Other advisors in the chain can intercept and observe each tool call iteration * **Integration with Chat Memory**: Works seamlessly with Chat Memory advisors for conversation history management * **Extensibility**: The advisor can be extended to customize the tool calling behavior The `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. [source,java] ---- var toolCallAdvisor = ToolCallAdvisor.builder() .toolCallingManager(toolCallingManager) .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 300) .build(); var chatClient = ChatClient.builder(chatModel) .defaultAdvisors(toolCallAdvisor) .build(); String response = chatClient.prompt("What day is tomorrow?") .tools(new DateTimeTools()) .call() .content(); ---- ==== Configuration Options The `ToolCallAdvisor.Builder` supports the following configuration options: - `toolCallingManager`: The `ToolCallingManager` instance to use for executing tool calls. If not provided, a default instance is used. - `advisorOrder`: The order in which the advisor is applied in the chain. Must be between `BaseAdvisor.HIGHEST_PRECEDENCE` and `BaseAdvisor.LOWEST_PRECEDENCE`. - `conversationHistoryEnabled`: Controls whether the advisor maintains conversation history internally during tool call iterations. Default is `true`. ==== Conversation History Management By default (`conversationHistoryEnabled=true`), the `ToolCallAdvisor` maintains the full conversation history internally during tool call iterations. Each subsequent LLM call includes all previous messages. Use 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: [source,java] ---- var toolCallAdvisor = ToolCallAdvisor.builder() .toolCallingManager(toolCallingManager) .disableInternalConversationHistory() // Let ChatMemory handle history .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 300) .build(); var chatMemoryAdvisor = MessageChatMemoryAdvisor.builder(chatMemory) .advisorOrder(BaseAdvisor.HIGHEST_PRECEDENCE + 200) // Before ToolCallAdvisor .build(); var chatClient = ChatClient.builder(chatModel) .defaultAdvisors(chatMemoryAdvisor, toolCallAdvisor) .build(); ---- ==== Return Direct The `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. For more details about `ToolCallAdvisor`, see xref:api/advisors-recursive.adoc#_toolcalladvisor[Recursive Advisors - ToolCallAdvisor]. === User-Controlled Tool Execution There 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`. When 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`. The following example demonstrates a minimal implementation of the user-controlled tool execution approach: [source,java] ---- ChatModel chatModel = ... ToolCallingManager toolCallingManager = ToolCallingManager.builder().build(); ChatOptions chatOptions = ToolCallingChatOptions.builder() .toolCallbacks(new CustomerTools()) .internalToolExecutionEnabled(false) .build(); Prompt prompt = new Prompt("Tell me more about the customer with ID 42", chatOptions); ChatResponse chatResponse = chatModel.call(prompt); while (chatResponse.hasToolCalls()) { ToolExecutionResult toolExecutionResult = toolCallingManager.executeToolCalls(prompt, chatResponse); prompt = new Prompt(toolExecutionResult.conversationHistory(), chatOptions); chatResponse = chatModel.call(prompt); } System.out.println(chatResponse.getResult().getOutput().getText()); ---- NOTE: 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. The next examples shows a minimal implementation of the user-controlled tool execution approach combined with the usage of the `ChatMemory` API: [source,java] ---- ToolCallingManager toolCallingManager = DefaultToolCallingManager.builder().build(); ChatMemory chatMemory = MessageWindowChatMemory.builder().build(); String conversationId = UUID.randomUUID().toString(); ChatOptions chatOptions = ToolCallingChatOptions.builder() .toolCallbacks(ToolCallbacks.from(new MathTools())) .internalToolExecutionEnabled(false) .build(); Prompt prompt = new Prompt( List.of(new SystemMessage("You are a helpful assistant."), new UserMessage("What is 6 * 8?")), chatOptions); chatMemory.add(conversationId, prompt.getInstructions()); Prompt promptWithMemory = new Prompt(chatMemory.get(conversationId), chatOptions); ChatResponse chatResponse = chatModel.call(promptWithMemory); chatMemory.add(conversationId, chatResponse.getResult().getOutput()); while (chatResponse.hasToolCalls()) { ToolExecutionResult toolExecutionResult = toolCallingManager.executeToolCalls(promptWithMemory, chatResponse); chatMemory.add(conversationId, toolExecutionResult.conversationHistory() .get(toolExecutionResult.conversationHistory().size() - 1)); promptWithMemory = new Prompt(chatMemory.get(conversationId), chatOptions); chatResponse = chatModel.call(promptWithMemory); chatMemory.add(conversationId, chatResponse.getResult().getOutput()); } UserMessage newUserMessage = new UserMessage("What did I ask you earlier?"); chatMemory.add(conversationId, newUserMessage); ChatResponse newResponse = chatModel.call(new Prompt(chatMemory.get(conversationId))); ---- === Exception Handling When a tool call fails, the exception is propagated as a `ToolExecutionException` which can be caught to handle the error. A `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. [source,java] ---- @FunctionalInterface public interface ToolExecutionExceptionProcessor { /** * Convert an exception thrown by a tool to a String that can be sent back to the AI * model or throw an exception to be handled by the caller. */ String process(ToolExecutionException exception); } ---- If 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. You can use the ``spring.ai.tools.throw-exception-on-error` property to control the behavior of the `DefaultToolExecutionExceptionProcessor` bean: [cols="6,3,1", stripes=even] |==== | Property | Description | Default | `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` |==== [source,java] ---- @Bean ToolExecutionExceptionProcessor toolExecutionExceptionProcessor() { return new DefaultToolExecutionExceptionProcessor(true); } ---- NOTE: 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. The `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. == Tool Resolution The main approach for passing tools to a model is by providing the `ToolCallback`(s) when invoking the `ChatClient` or the `ChatModel`, using one of the strategies described in xref:_methods_as_tools[] and xref:_functions_as_tools[]. However, Spring AI also supports resolving tools dynamically at runtime using the `ToolCallbackResolver` interface. [source,java] ---- public interface ToolCallbackResolver { /** * Resolve the {@link ToolCallback} for the given tool name. */ @Nullable ToolCallback resolve(String toolName); } ---- When using this approach: - On the client-side, you provide the tool names to the `ChatClient` or the `ChatModel` instead of the `ToolCallback`(s). - On the server-side, a `ToolCallbackResolver` implementation is responsible for resolving the tool names to the corresponding `ToolCallback` instances. By default, Spring AI relies on a `DelegatingToolCallbackResolver` that delegates the tool resolution to a list of `ToolCallbackResolver` instances: - The `SpringBeanToolCallbackResolver` resolves tools from Spring beans of type `Function`, `Supplier`, `Consumer`, or `BiFunction`. See xref:_dynamic_specification_bean[] for more details. - 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. If you rely on the Spring Boot Autoconfiguration, you can customize the resolution logic by providing a custom `ToolCallbackResolver` bean. [source,java] ---- @Bean ToolCallbackResolver toolCallbackResolver(List toolCallbacks) { StaticToolCallbackResolver staticToolCallbackResolver = new StaticToolCallbackResolver(toolCallbacks); return new DelegatingToolCallbackResolver(List.of(staticToolCallbackResolver)); } ---- The `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[]. [[tool-argument-augmentation]] == Tool Argument Augmentation Spring 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. Common use cases include: * **Inner Thinking/Reasoning**: Capture the model's step-by-step reasoning before executing a tool * **Memory Enhancement**: Extract insights to store in long-term memory * **Analytics & Tracking**: Collect metadata, user intent, or usage patterns * **Multi-Agent Coordination**: Pass agent identifiers or coordination signals === Quick Start **Define augmented arguments** as a Java Record: [source,java] ---- public record AgentThinking( @ToolParam(description = "Your reasoning for calling this tool", required = true) String innerThought, @ToolParam(description = "Confidence level (low, medium, high)", required = false) String confidence ) {} ---- **Wrap your tool** with `AugmentedToolCallbackProvider`: [source,java] ---- AugmentedToolCallbackProvider provider = AugmentedToolCallbackProvider .builder() .toolObject(new MyTools()) // Your @Tool annotated class .argumentType(AgentThinking.class) .argumentConsumer(event -> { AgentThinking thinking = event.arguments(); log.info("Tool: {} | Reasoning: {}", event.toolDefinition().name(), thinking.innerThought()); }) .removeExtraArgumentsAfterProcessing(true) .build(); ---- **Use with ChatClient**: [source,java] ---- ChatClient chatClient = ChatClient.builder(chatModel) .defaultToolCallbacks(provider) .build(); ---- The LLM sees the augmented schema with your additional fields. Your consumer receives the `AgentThinking` record, while the original tool receives only its expected arguments. === Core Components * `AugmentedToolCallbackProvider` - Wraps tool objects or providers, augmenting all tools with the specified Record type * `AugmentedToolCallback` - Wraps individual `ToolCallback` instances * `AugmentedArgumentEvent` - Contains `toolDefinition()`, `rawInput()`, and `arguments()` for consumers * `ToolInputSchemaAugmenter` - Low-level utility for schema manipulation === Configuration The `removeExtraArgumentsAfterProcessing` option controls whether augmented arguments are passed to the original tool: * `true` (default) - Remove augmented arguments before calling the tool * `false` - Preserve augmented arguments in the input (if the tool can ignore extra fields) == Observability Tool 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]. Optionally, 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]. === Logging All 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. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/transcriptions.adoc ================================================ [[Transcription]] = Transcription Model API Spring AI provides support for OpenAI's Transcription Model API. When additional providers for Transcription are implemented, a common `AudioTranscriptionModel` interface will be extracted. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/usage-handling.adoc ================================================ = Using Chat/Embedding Response Usage == Overview Spring AI has enhanced its Model Usage handling by introducing `getNativeUsage()` method in the Usage interface and providing a `DefaultUsage` implementation. This change simplifies how different AI models can track and report their usage metrics while maintaining consistency across the framework. == Key Changes === Usage Interface Enhancement The `Usage` interface now includes a new method: ```java Object getNativeUsage(); ``` This method allows access to the model-specific native usage data, enabling more detailed usage tracking when needed. === Using with ChatModel Here's a complete example showing how to track usage with OpenAI's ChatModel: ```java @SpringBootConfiguration public class Configuration { @Bean public OpenAiApi chatCompletionApi() { return OpenAiApi.builder() .apiKey(System.getenv("OPENAI_API_KEY")) .build(); } @Bean public OpenAiChatModel openAiClient(OpenAiApi openAiApi) { return OpenAiChatModel.builder() .openAiApi(openAiApi) .build(); } } @Service public class ChatService { private final OpenAiChatModel chatModel; public ChatService(OpenAiChatModel chatModel) { this.chatModel = chatModel; } public void demonstrateUsage() { // Create a chat prompt Prompt prompt = new Prompt("What is the weather like today?"); // Get the chat response ChatResponse response = this.chatModel.call(prompt); // Access the usage information Usage usage = response.getMetadata().getUsage(); // Get standard usage metrics System.out.println("Prompt Tokens: " + usage.getPromptTokens()); System.out.println("Completion Tokens: " + usage.getCompletionTokens()); System.out.println("Total Tokens: " + usage.getTotalTokens()); // Access native OpenAI usage data with detailed token information if (usage.getNativeUsage() instanceof org.springframework.ai.openai.api.OpenAiApi.Usage) { org.springframework.ai.openai.api.OpenAiApi.Usage nativeUsage = (org.springframework.ai.openai.api.OpenAiApi.Usage) usage.getNativeUsage(); // Detailed prompt token information System.out.println("Prompt Tokens Details:"); System.out.println("- Audio Tokens: " + nativeUsage.promptTokensDetails().audioTokens()); System.out.println("- Cached Tokens: " + nativeUsage.promptTokensDetails().cachedTokens()); // Detailed completion token information System.out.println("Completion Tokens Details:"); System.out.println("- Reasoning Tokens: " + nativeUsage.completionTokenDetails().reasoningTokens()); System.out.println("- Accepted Prediction Tokens: " + nativeUsage.completionTokenDetails().acceptedPredictionTokens()); System.out.println("- Audio Tokens: " + nativeUsage.completionTokenDetails().audioTokens()); System.out.println("- Rejected Prediction Tokens: " + nativeUsage.completionTokenDetails().rejectedPredictionTokens()); } } } ``` === Using with ChatClient If you are using the `ChatClient`, you can access the usage information using the `ChatResponse` object: ```java // Create a chat prompt Prompt prompt = new Prompt("What is the weather like today?"); // Create a chat client ChatClient chatClient = ChatClient.create(chatModel); // Get the chat response ChatResponse response = chatClient.prompt(prompt) .call() .chatResponse(); // Access the usage information Usage usage = response.getMetadata().getUsage(); ``` == Prompt Cache Usage Metrics For providers that support prompt caching, the `Usage` interface provides unified access to cache metrics without requiring provider-specific casting: ```java Usage usage = response.getMetadata().getUsage(); // Unified cache metrics — works across all providers Long cacheReadTokens = usage.getCacheReadInputTokens(); Long cacheWriteTokens = usage.getCacheWriteInputTokens(); if (cacheReadTokens != null && cacheReadTokens > 0) { System.out.println("Cache hit: " + cacheReadTokens + " tokens read from cache"); } if (cacheWriteTokens != null && cacheWriteTokens > 0) { System.out.println("Cache write: " + cacheWriteTokens + " tokens written to cache"); } ``` These methods return `null` for providers that do not support prompt caching. The following table shows prompt cache metrics availability by provider: [cols="1,1,1"] |=== |Provider |Cache Read Tokens |Cache Write Tokens |Anthropic |Yes |Yes (`cacheCreationInputTokens`) |AWS Bedrock |Yes |Yes |OpenAI |Yes (`cachedTokens`) |No |Google Gemini |Yes (`cachedContentTokenCount`) |No |DeepSeek |No |No |Mistral |No |No |Ollama |No |No |=== NOTE: For detailed provider-specific cache metrics (such as per-modality cache breakdowns in Gemini), use `getNativeUsage()` to access the provider's native usage object. == Benefits **Standardization**: Provides a consistent way to handle usage across different AI models **Flexibility**: Supports model-specific usage data through the native usage feature **Simplification**: Reduces boilerplate code with the default implementation **Extensibility**: Easy to extend for specific model requirements while maintaining compatibility === Type Safety Considerations When working with native usage data, consider type casting carefully: ```java // Safe way to access native usage if (usage.getNativeUsage() instanceof org.springframework.ai.openai.api.OpenAiApi.Usage) { org.springframework.ai.openai.api.OpenAiApi.Usage nativeUsage = (org.springframework.ai.openai.api.OpenAiApi.Usage) usage.getNativeUsage(); // Work with native usage data } ``` ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/apache-cassandra.adoc ================================================ = Apache Cassandra Vector Store This section walks you through setting up `CassandraVectorStore` to store document embeddings and perform similarity searches. == What is Apache Cassandra? link: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. Its Vector Similarity Search (VSS) is based on the JVector library that ensures best-in-class performance and relevancy. A vector search in Apache Cassandra is done as simply as: [source,sql] ---- SELECT content FROM table ORDER BY content_vector ANN OF query_embedding; ---- More docs on this can be read https://cassandra.apache.org/doc/latest/cassandra/getting-started/vector-search-quickstart.html[here]. This 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. The store can also be used for non-RAG use-cases in an existing database, e.g. semantic searches, geo-proximity searches, etc. The 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`. When 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. == What is JVector? link:https://github.com/jbellis/jvector[JVector] is a pure Java embedded vector search engine. It stands out from other HNSW Vector Similarity Search implementations by being: * Algorithmic-fast. JVector uses state of the art graph algorithms inspired by DiskANN and related research that offer high recall and low latency. * Implementation-fast. JVector uses the Panama SIMD API to accelerate index build and queries. * Memory efficient. JVector compresses vectors using product quantization so they can stay in memory during searches. * Disk-aware. JVector's disk layout is designed to do the minimum necessary iops at query time. * Concurrent. Index builds scale linearly to at least 32 threads. Double the threads, half the build time. * Incremental. Query your index as you build it. No delay between adding a vector and being able to find it in search results. * Easy to embed. API designed for easy embedding, by people using it in production. == Prerequisites 1. A `EmbeddingModel` instance to compute the document embeddings. This is usually configured as a Spring Bean. Several options are available: - `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. - 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]. - There are many more choices, see `Embeddings API` docs. 2. An Apache Cassandra instance, from version 5.0-beta1 a. link:https://cassandra.apache.org/_/quickstart.html[DIY Quick Start] b. For a managed offering https://astra.datastax.com/[Astra DB] offers a healthy free tier offering. == Dependencies [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== TIP: For dependency management, we recommend using the Spring AI BOM as explained in the xref:getting-started.adoc#dependency-management[Dependency Management] section. Add these dependencies to your project: * For just the Cassandra Vector Store: [source,xml] ---- org.springframework.ai spring-ai-cassandra-store ---- * Or, for everything you need in a RAG application (using the default ONNX Embedding Model): [source,xml] ---- org.springframework.ai spring-ai-starter-vector-store-cassandra ---- == Configuration Properties You can use the following properties in your Spring Boot configuration to customize the Apache Cassandra vector store. [cols="2,1",stripes=even] |=== |Property|Default Value |`spring.ai.vectorstore.cassandra.keyspace`|springframework |`spring.ai.vectorstore.cassandra.table`|ai_vector_store |`spring.ai.vectorstore.cassandra.initialize-schema`|false |`spring.ai.vectorstore.cassandra.index-name`| |`spring.ai.vectorstore.cassandra.content-column-name`|content |`spring.ai.vectorstore.cassandra.embedding-column-name`|embedding |`spring.ai.vectorstore.cassandra.fixed-thread-pool-executor-size`|16 |=== == Usage === Basic Usage Create a CassandraVectorStore instance as a Spring Bean: [source,java] ---- @Bean public VectorStore vectorStore(CqlSession session, EmbeddingModel embeddingModel) { return CassandraVectorStore.builder(embeddingModel) .session(session) .keyspace("my_keyspace") .table("my_vectors") .build(); } ---- Once you have the vector store instance, you can add documents and perform searches: [source,java] ---- // Add documents vectorStore.add(List.of( new Document("1", "content1", Map.of("key1", "value1")), new Document("2", "content2", Map.of("key2", "value2")) )); // Search with filters List results = vectorStore.similaritySearch( SearchRequest.query("search text") .withTopK(5) .withSimilarityThreshold(0.7f) .withFilterExpression("metadata.key1 == 'value1'") ); ---- === Advanced Configuration For more complex use cases, you can configure additional settings in your Spring Bean: [source,java] ---- @Bean public VectorStore vectorStore(CqlSession session, EmbeddingModel embeddingModel) { return CassandraVectorStore.builder(embeddingModel) .session(session) .keyspace("my_keyspace") .table("my_vectors") // Configure primary keys .partitionKeys(List.of( new SchemaColumn("id", DataTypes.TEXT), new SchemaColumn("category", DataTypes.TEXT) )) .clusteringKeys(List.of( new SchemaColumn("timestamp", DataTypes.TIMESTAMP) )) // Add metadata columns with optional indexing .addMetadataColumns( new SchemaColumn("category", DataTypes.TEXT, SchemaColumnTags.INDEXED), new SchemaColumn("score", DataTypes.DOUBLE) ) // Customize column names .contentColumnName("text") .embeddingColumnName("vector") // Performance tuning .fixedThreadPoolExecutorSize(32) // Schema management .initializeSchema(true) // Custom batching strategy .batchingStrategy(new TokenCountBatchingStrategy()) .build(); } ---- === Connection Configuration There are two ways to configure the connection to Cassandra: * Using an injected CqlSession (recommended): [source,java] ---- @Bean public VectorStore vectorStore(CqlSession session, EmbeddingModel embeddingModel) { return CassandraVectorStore.builder(embeddingModel) .session(session) .keyspace("my_keyspace") .table("my_vectors") .build(); } ---- * Using connection details directly in the builder: [source,java] ---- @Bean public VectorStore vectorStore(EmbeddingModel embeddingModel) { return CassandraVectorStore.builder(embeddingModel) .contactPoint(new InetSocketAddress("localhost", 9042)) .localDatacenter("datacenter1") .keyspace("my_keyspace") .build(); } ---- === Metadata Filtering You 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`. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch( SearchRequest.builder().query("The World") .topK(5) .filterExpression("country in ['UK', 'NL'] && year >= 2020").build()); ---- or programmatically using the expression DSL: [source,java] ---- Filter.Expression f = new FilterExpressionBuilder() .and( f.in("country", "UK", "NL"), f.gte("year", 2020) ).build(); vectorStore.similaritySearch( SearchRequest.builder().query("The World") .topK(5) .filterExpression(f).build()); ---- The portable filter expressions get automatically converted into link:https://cassandra.apache.org/doc/latest/cassandra/developing/cql/index.html[CQL queries]. == Advanced Example: Vector Store on top of Wikipedia Dataset The 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. First, create the schema in the Cassandra database: [source,bash] ---- wget https://s.apache.org/colbert-wikipedia-schema-cql -O colbert-wikipedia-schema.cql cqlsh -f colbert-wikipedia-schema.cql ---- Then configure the store using the builder pattern: [source,java] ---- @Bean public VectorStore vectorStore(CqlSession session, EmbeddingModel embeddingModel) { List partitionColumns = List.of( new SchemaColumn("wiki", DataTypes.TEXT), new SchemaColumn("language", DataTypes.TEXT), new SchemaColumn("title", DataTypes.TEXT) ); List clusteringColumns = List.of( new SchemaColumn("chunk_no", DataTypes.INT), new SchemaColumn("bert_embedding_no", DataTypes.INT) ); List extraColumns = List.of( new SchemaColumn("revision", DataTypes.INT), new SchemaColumn("id", DataTypes.INT) ); return CassandraVectorStore.builder() .session(session) .embeddingModel(embeddingModel) .keyspace("wikidata") .table("articles") .partitionKeys(partitionColumns) .clusteringKeys(clusteringColumns) .contentColumnName("body") .embeddingColumnName("all_minilm_l6_v2_embedding") .indexName("all_minilm_l6_v2_ann") .initializeSchema(false) .addMetadataColumns(extraColumns) .primaryKeyTranslator((List primaryKeys) -> { if (primaryKeys.isEmpty()) { return "test§¶0"; } return String.format("%s§¶%s", primaryKeys.get(2), primaryKeys.get(3)); }) .documentIdTranslator((id) -> { String[] parts = id.split("§¶"); String title = parts[0]; int chunk_no = parts.length > 1 ? Integer.parseInt(parts[1]) : 0; return List.of("simplewiki", "en", title, chunk_no, 0); }) .build(); } @Bean public EmbeddingModel embeddingModel() { // default is ONNX all-MiniLM-L6-v2 which is what we want return new TransformersEmbeddingModel(); } ---- === Loading the Complete Wikipedia Dataset To load the full wikipedia dataset: 1. Download `simplewiki-sstable.tar` from https://s.apache.org/simplewiki-sstable-tar (this will take a while, the file is tens of GBs) 2. Load the data: [source,bash] ---- tar -xf simplewiki-sstable.tar -C ${CASSANDRA_DATA}/data/wikidata/articles-*/ nodetool import wikidata articles ${CASSANDRA_DATA}/data/wikidata/articles-*/ ---- [NOTE] ==== * If you have existing data in this table, check the tarball's files don't clobber existing sstables when doing the `tar`. * An alternative to `nodetool import` is to just restart Cassandra. * If there are any failures in the indexes they will be rebuilt automatically. ==== == Accessing the Native Client The Cassandra Vector Store implementation provides access to the underlying native Cassandra client (`CqlSession`) through the `getNativeClient()` method: [source,java] ---- CassandraVectorStore vectorStore = context.getBean(CassandraVectorStore.class); Optional nativeClient = vectorStore.getNativeClient(); if (nativeClient.isPresent()) { CqlSession session = nativeClient.get(); // Use the native client for Cassandra-specific operations } ---- The native client gives you access to Cassandra-specific features and operations that might not be exposed through the `VectorStore` interface. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/azure-cosmos-db.adoc ================================================ = Azure Cosmos DB This section walks you through setting up `CosmosDBVectorStore` to store document embeddings and perform similarity searches. == What is Azure Cosmos DB? link: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. It offers high availability, low latency, and the ability to scale horizontally to meet modern application demands. It was built from the ground up with global distribution, fine-grained multi-tenancy, and horizontal scalability at its core. It 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. It 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. == What is DiskANN? DiskANN (Disk-based Approximate Nearest Neighbor Search) is an innovative technology used in Azure Cosmos DB to enhance the performance of vector searches. It enables efficient and scalable similarity searches across high-dimensional data by indexing embeddings stored in Cosmos DB. DiskANN provides the following benefits: * **Efficiency**: By utilizing disk-based structures, DiskANN significantly reduces the time required to find nearest neighbors compared to traditional methods. * **Scalability**: It can handle large datasets that exceed memory capacity, making it suitable for various applications, including machine learning and AI-driven solutions. * **Low Latency**: DiskANN minimizes latency during search operations, ensuring that applications can retrieve results quickly even with substantial data volumes. In the context of Spring AI for Azure Cosmos DB, vector searches will create and leverage DiskANN indexes to ensure optimal performance for similarity queries. == Setting up Azure Cosmos DB Vector Store with Auto Configuration The following code demonstrates how to set up the `CosmosDBVectorStore` with auto-configuration: ```java package com.example.demo; import io.micrometer.observation.ObservationRegistry; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.ai.document.Document; import org.springframework.ai.vectorstore.SearchRequest; import org.springframework.ai.vectorstore.VectorStore; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Lazy; import java.util.List; import java.util.Map; import java.util.UUID; import static org.assertj.core.api.Assertions.assertThat; @SpringBootApplication @EnableAutoConfiguration public class DemoApplication implements CommandLineRunner { private static final Logger log = LoggerFactory.getLogger(DemoApplication.class); @Lazy @Autowired private VectorStore vectorStore; public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } @Override public void run(String... args) throws Exception { Document document1 = new Document(UUID.randomUUID().toString(), "Sample content1", Map.of("key1", "value1")); Document document2 = new Document(UUID.randomUUID().toString(), "Sample content2", Map.of("key2", "value2")); this.vectorStore.add(List.of(document1, document2)); List results = this.vectorStore.similaritySearch(SearchRequest.builder().query("Sample content").topK(1).build()); log.info("Search results: {}", results); // Remove the documents from the vector store this.vectorStore.delete(List.of(document1.getId(), document2.getId())); } @Bean public ObservationRegistry observationRegistry() { return ObservationRegistry.create(); } } ``` == Auto Configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Add the following dependency to your Maven project: [source,xml] ---- org.springframework.ai spring-ai-starter-vector-store-azure-cosmos-db ---- == Configuration Properties The following configuration properties are available for the Cosmos DB vector store: [stripes=even] |=== | Property | Description | spring.ai.vectorstore.cosmosdb.databaseName | The name of the Cosmos DB database to use. | spring.ai.vectorstore.cosmosdb.containerName | The name of the Cosmos DB container to use. | spring.ai.vectorstore.cosmosdb.partitionKeyPath | The path for the partition key. | spring.ai.vectorstore.cosmosdb.metadataFields | Comma-separated list of metadata fields. | spring.ai.vectorstore.cosmosdb.vectorStoreThroughput | The throughput for the vector store. | spring.ai.vectorstore.cosmosdb.vectorDimensions | The number of dimensions for the vectors. | spring.ai.vectorstore.cosmosdb.endpoint | The endpoint for the Cosmos DB. | spring.ai.vectorstore.cosmosdb.key | The key for the Cosmos DB (if key is not present, [DefaultAzureCredential](https://learn.microsoft.com/azure/developer/java/sdk/authentication/credential-chains#defaultazurecredential-overview) will be used). |=== == Complex Searches with Filters You can perform more complex searches using filters in the Cosmos DB vector store. Below is a sample demonstrating how to use filters in your search queries. [source,java] ---- Map metadata1 = new HashMap<>(); metadata1.put("country", "UK"); metadata1.put("year", 2021); metadata1.put("city", "London"); Map metadata2 = new HashMap<>(); metadata2.put("country", "NL"); metadata2.put("year", 2022); metadata2.put("city", "Amsterdam"); Document document1 = new Document("1", "A document about the UK", this.metadata1); Document document2 = new Document("2", "A document about the Netherlands", this.metadata2); vectorStore.add(List.of(document1, document2)); FilterExpressionBuilder builder = new FilterExpressionBuilder(); List results = vectorStore.similaritySearch(SearchRequest.builder().query("The World") .topK(10) .filterExpression((this.builder.in("country", "UK", "NL")).build()).build()); ---- == Setting up Azure Cosmos DB Vector Store without Auto Configuration The following code demonstrates how to set up the `CosmosDBVectorStore` without relying on auto-configuration. [DefaultAzureCredential](https://learn.microsoft.com/azure/developer/java/sdk/authentication/credential-chains#defaultazurecredential-overview) is recommended for authentication to Azure Cosmos DB. [source,java] ---- @Bean public VectorStore vectorStore(ObservationRegistry observationRegistry) { // Create the Cosmos DB client CosmosAsyncClient cosmosClient = new CosmosClientBuilder() .endpoint(System.getenv("COSMOSDB_AI_ENDPOINT")) .credential(new DefaultAzureCredentialBuilder().build()) .userAgentSuffix("SpringAI-CDBNoSQL-VectorStore") .gatewayMode() .buildAsyncClient(); // Create and configure the vector store return CosmosDBVectorStore.builder(cosmosClient, embeddingModel) .databaseName("test-database") .containerName("test-container") // Configure metadata fields for filtering .metadataFields(List.of("country", "year", "city")) // Set the partition key path (optional) .partitionKeyPath("/id") // Configure performance settings .vectorStoreThroughput(1000) .vectorDimensions(1536) // Match your embedding model's dimensions // Add custom batching strategy (optional) .batchingStrategy(new TokenCountBatchingStrategy()) // Add observation registry for metrics .observationRegistry(observationRegistry) .build(); } @Bean public EmbeddingModel embeddingModel() { return new TransformersEmbeddingModel(); } ---- This configuration shows all the available builder options: * `databaseName`: The name of your Cosmos DB database * `containerName`: The name of your container within the database * `partitionKeyPath`: The path for the partition key (e.g., "/id") * `metadataFields`: List of metadata fields that will be used for filtering * `vectorStoreThroughput`: The throughput (RU/s) for the vector store container * `vectorDimensions`: The number of dimensions for your vectors (should match your embedding model) * `batchingStrategy`: Strategy for batching document operations (optional) == Manual Dependency Setup Add the following dependency in your Maven project: [source,xml] ---- org.springframework.ai spring-ai-azure-cosmos-db-store ---- == Accessing the Native Client The Azure Cosmos DB Vector Store implementation provides access to the underlying native Azure Cosmos DB client (`CosmosClient`) through the `getNativeClient()` method: [source,java] ---- CosmosDBVectorStore vectorStore = context.getBean(CosmosDBVectorStore.class); Optional nativeClient = vectorStore.getNativeClient(); if (nativeClient.isPresent()) { CosmosClient client = nativeClient.get(); // Use the native client for Azure Cosmos DB-specific operations } ---- The native client gives you access to Azure Cosmos DB-specific features and operations that might not be exposed through the `VectorStore` interface. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/azure.adoc ================================================ = Azure AI Service This section will walk you through setting up the `AzureVectorStore` to store document embeddings and perform similarity searches using the Azure AI Search Service. link: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. == Prerequisites 1. Azure Subscription: You will need an link:https://azure.microsoft.com/en-us/free/[Azure subscription] to use any Azure service. 2. 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. 3. (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`. == Configuration On 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. NOTE: this is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default. Alternatively, you can create the index manually. To set up an AzureVectorStore, you will need the settings retrieved from the prerequisites above along with your index name: * Azure AI Search Endpoint * Azure AI Search Key * (optional) Azure OpenAI API Endpoint * (optional) Azure OpenAI API Key You can provide these values as OS environment variables. [source,bash] ---- export AZURE_AI_SEARCH_API_KEY= export AZURE_AI_SEARCH_ENDPOINT= export OPENAI_API_KEY= (Optional) ---- [NOTE] ==== You 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. ==== == Dependencies [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Add these dependencies to your project: === 1. Select an Embeddings interface implementation. You can choose between: [tabs] ====== OpenAI Embedding:: + [source,xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- Azure AI Embedding:: + [source,xml] ---- org.springframework.ai spring-ai-starter-model-azure-openai ---- Local Sentence Transformers Embedding:: + [source,xml] ---- org.springframework.ai spring-ai-starter-model-transformers ---- ====== === 2. Azure (AI Search) Vector Store [source,xml] ---- org.springframework.ai spring-ai-azure-store ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. == Configuration Properties You can use the following properties in your Spring Boot configuration to customize the Azure vector store. [stripes=even] |=== |Property|Default value |`spring.ai.vectorstore.azure.url`| |`spring.ai.vectorstore.azure.api-key`| |`spring.ai.vectorstore.azure.useKeylessAuth`|false |`spring.ai.vectorstore.azure.initialize-schema`|false |`spring.ai.vectorstore.azure.index-name`|spring_ai_azure_vector_store |`spring.ai.vectorstore.azure.default-top-k`|4 |`spring.ai.vectorstore.azure.default-similarity-threshold`|0.0 |`spring.ai.vectorstore.azure.content-field-name`|content |`spring.ai.vectorstore.azure.embedding-field-name`|embedding |`spring.ai.vectorstore.azure.metadata-field-name`|metadata |=== == Sample Code To configure an Azure `SearchIndexClient` in your application, you can use the following code: [source,java] ---- @Bean public SearchIndexClient searchIndexClient() { return new SearchIndexClientBuilder().endpoint(System.getenv("AZURE_AI_SEARCH_ENDPOINT")) .credential(new AzureKeyCredential(System.getenv("AZURE_AI_SEARCH_API_KEY"))) .buildClient(); } ---- To 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. [source,java] ---- @Bean public VectorStore vectorStore(SearchIndexClient searchIndexClient, EmbeddingModel embeddingModel) { return AzureVectorStore.builder(searchIndexClient, embeddingModel) .initializeSchema(true) // Define the metadata fields to be used // in the similarity search filters. .filterMetadataFields(List.of(MetadataField.text("country"), MetadataField.int64("year"), MetadataField.date("activationDate"))) .defaultTopK(5) .defaultSimilarityThreshold(0.7) .indexName("spring-ai-document-index") .build(); } ---- [NOTE] ==== You 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`. If the filterable metadata fields are expanded with new entries, you have to (re)upload/update the documents with this metadata. ==== In your main code, create some documents: [source,java] ---- List documents = List.of( new Document("Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!", Map.of("country", "BG", "year", 2020)), new Document("The World is Big and Salvation Lurks Around the Corner"), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("country", "NL", "year", 2023))); ---- Add the documents to your vector store: [source,java] ---- vectorStore.add(documents); ---- And finally, retrieve documents similar to a query: [source,java] ---- List results = vectorStore.similaritySearch( SearchRequest.builder() .query("Spring") .topK(5).build()); ---- If all goes well, you should retrieve the document containing the text "Spring AI rocks!!". === Metadata filtering You can leverage the generic, portable link:https://docs.spring.io/spring-ai/reference/api/vectordbs.html#_metadata_filters[metadata filters] with AzureVectorStore as well. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch( SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression("country in ['UK', 'NL'] && year >= 2020").build()); ---- or programmatically using the expression DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch( SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression(b.and( b.in("country", "UK", "NL"), b.gte("year", 2020)).build()).build()); ---- The 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: [source,sql] ---- country in ['UK', 'NL'] && year >= 2020 ---- is converted into the following Azure OData link:https://learn.microsoft.com/en-us/azure/search/search-query-odata-filter[filter expression]: [source,graphql] ---- $filter search.in(meta_country, 'UK,NL', ',') and meta_year ge 2020 ---- == Custom Field Names By default, the Azure Vector Store uses the following field names in the Azure AI Search index: * `content` - for document text * `embedding` - for vector embeddings * `metadata` - for document metadata However, when working with existing Azure AI Search indexes that use different field names, you can configure custom field names to match your index schema. This allows you to integrate Spring AI with pre-existing indexes without needing to modify them. === Use Cases Custom field names are particularly useful when: * **Integrating with existing indexes**: Your organization already has Azure AI Search indexes with established field naming conventions (e.g., `chunk_text`, `vector`, `meta_data`). * **Following naming standards**: Your team follows specific naming conventions that differ from the defaults. * **Migrating from other systems**: You're migrating from another vector database or search system and want to maintain consistent field names. === Configuration via Properties You can configure custom field names using Spring Boot application properties: [source,properties] ---- spring.ai.vectorstore.azure.url=${AZURE_AI_SEARCH_ENDPOINT} spring.ai.vectorstore.azure.api-key=${AZURE_AI_SEARCH_API_KEY} spring.ai.vectorstore.azure.index-name=my-existing-index spring.ai.vectorstore.azure.initialize-schema=false # Custom field names to match existing index schema spring.ai.vectorstore.azure.content-field-name=chunk_text spring.ai.vectorstore.azure.embedding-field-name=vector spring.ai.vectorstore.azure.metadata-field-name=meta_data ---- IMPORTANT: 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. === Configuration via Builder API Alternatively, you can configure custom field names programmatically using the builder API: [source,java] ---- @Bean public VectorStore vectorStore(SearchIndexClient searchIndexClient, EmbeddingModel embeddingModel) { return AzureVectorStore.builder(searchIndexClient, embeddingModel) .indexName("my-existing-index") .initializeSchema(false) // Don't create schema - use existing index // Configure custom field names to match existing index .contentFieldName("chunk_text") .embeddingFieldName("vector") .metadataFieldName("meta_data") .filterMetadataFields(List.of( MetadataField.text("category"), MetadataField.text("source"))) .build(); } ---- === Complete Example: Working with Existing Index Here's a complete example showing how to use Spring AI with an existing Azure AI Search index that has custom field names: [source,java] ---- @Configuration public class VectorStoreConfig { @Bean public SearchIndexClient searchIndexClient() { return new SearchIndexClientBuilder() .endpoint(System.getenv("AZURE_AI_SEARCH_ENDPOINT")) .credential(new AzureKeyCredential(System.getenv("AZURE_AI_SEARCH_API_KEY"))) .buildClient(); } @Bean public VectorStore vectorStore(SearchIndexClient searchIndexClient, EmbeddingModel embeddingModel) { return AzureVectorStore.builder(searchIndexClient, embeddingModel) .indexName("production-documents-index") .initializeSchema(false) // Use existing index // Map to existing index field names .contentFieldName("document_text") .embeddingFieldName("text_vector") .metadataFieldName("document_metadata") // Define filterable metadata fields from existing schema .filterMetadataFields(List.of( MetadataField.text("department"), MetadataField.int64("year"), MetadataField.date("created_date"))) .defaultTopK(10) .defaultSimilarityThreshold(0.75) .build(); } } ---- You can then use the vector store as normal: [source,java] ---- // Search using the existing index with custom field names List results = vectorStore.similaritySearch( SearchRequest.builder() .query("artificial intelligence") .topK(5) .filterExpression("department == 'Engineering' && year >= 2023") .build()); // The results contain documents with text from the 'document_text' field results.forEach(doc -> System.out.println(doc.getText())); ---- === Creating New Index with Custom Field Names You can also create a new index with custom field names by setting `initializeSchema=true`: [source,java] ---- @Bean public VectorStore vectorStore(SearchIndexClient searchIndexClient, EmbeddingModel embeddingModel) { return AzureVectorStore.builder(searchIndexClient, embeddingModel) .indexName("new-custom-index") .initializeSchema(true) // Create new index with custom field names .contentFieldName("text_content") .embeddingFieldName("content_vector") .metadataFieldName("doc_metadata") .filterMetadataFields(List.of( MetadataField.text("category"), MetadataField.text("author"))) .build(); } ---- This will create a new Azure AI Search index with your custom field names, allowing you to establish your own naming conventions from the start. == Accessing the Native Client The Azure Vector Store implementation provides access to the underlying native Azure Search client (`SearchClient`) through the `getNativeClient()` method: [source,java] ---- AzureVectorStore vectorStore = context.getBean(AzureVectorStore.class); Optional nativeClient = vectorStore.getNativeClient(); if (nativeClient.isPresent()) { SearchClient client = nativeClient.get(); // Use the native client for Azure Search-specific operations } ---- The native client gives you access to Azure Search-specific features and operations that might not be exposed through the `VectorStore` interface. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/bedrock-knowledge-base.adoc ================================================ = Amazon Bedrock Knowledge Base This section walks you through setting up the Amazon Bedrock Knowledge Base `VectorStore` to perform similarity searches against a pre-configured Knowledge Base. link:https://docs.aws.amazon.com/bedrock/latest/userguide/knowledge-base.html[Amazon Bedrock Knowledge Bases] is a fully managed RAG (Retrieval-Augmented Generation) capability that allows you to connect foundation models to your data sources. Unlike other vector stores, Bedrock Knowledge Base handles document ingestion, chunking, and embedding internally. == Prerequisites 1. AWS Account with Bedrock access enabled 2. A configured Bedrock Knowledge Base with at least one data source synced 3. AWS credentials configured (via environment variables, AWS config file, or IAM role) [NOTE] ==== This vector store is read-only. Documents are managed through the Knowledge Base's data source sync process, not through the `add()` or `delete()` methods. ==== == Auto-configuration Spring AI provides Spring Boot auto-configuration for the Bedrock Knowledge Base Vector Store. To enable it, add the following dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-starter-vector-store-bedrock-knowledgebase ---- or to your Gradle `build.gradle` build file: [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-vector-store-bedrock-knowledgebase' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. [NOTE] ==== Unlike other vector stores, Bedrock Knowledge Base does not require an `EmbeddingModel` bean. The Knowledge Base handles embeddings internally during data source synchronization. ==== To connect to your Knowledge Base, provide the Knowledge Base ID via Spring Boot's `application.properties`: [source,properties] ---- spring.ai.vectorstore.bedrock-knowledge-base.knowledge-base-id=YOUR_KNOWLEDGE_BASE_ID spring.ai.vectorstore.bedrock-knowledge-base.region=us-east-1 ---- Or via environment variables: [source,bash] ---- export SPRING_AI_VECTORSTORE_BEDROCK_KNOWLEDGE_BASE_KNOWLEDGE_BASE_ID=YOUR_KNOWLEDGE_BASE_ID ---- Now you can auto-wire the Vector Store in your application: [source,java] ---- @Autowired VectorStore vectorStore; // ... // Retrieve documents similar to a query List results = vectorStore.similaritySearch( SearchRequest.builder() .query("What is the return policy?") .topK(5) .build()); ---- === Configuration Properties You can use the following properties in your Spring Boot configuration to customize the Bedrock Knowledge Base vector store. [stripes=even] |=== |Property | Description | Default value |`spring.ai.vectorstore.bedrock-knowledge-base.knowledge-base-id` | The ID of the Bedrock Knowledge Base to query | - |`spring.ai.vectorstore.bedrock-knowledge-base.region` | AWS region for the Bedrock service | SDK default |`spring.ai.vectorstore.bedrock-knowledge-base.top-k` | Number of results to return | 5 |`spring.ai.vectorstore.bedrock-knowledge-base.similarity-threshold` | Minimum similarity score (0.0 to 1.0) | 0.0 |`spring.ai.vectorstore.bedrock-knowledge-base.search-type` | Search type: SEMANTIC or HYBRID | null (KB default) |`spring.ai.vectorstore.bedrock-knowledge-base.reranking-model-arn` | ARN of Bedrock reranking model | null (disabled) |=== == Search Types Bedrock Knowledge Base supports two search types: * `SEMANTIC` - Vector similarity search only (default) * `HYBRID` - Combines semantic search with keyword search [NOTE] ==== HYBRID search is only available with OpenSearch-based vector stores. S3 Vectors, Aurora PostgreSQL, and other vector store types only support SEMANTIC search. ==== [source,properties] ---- spring.ai.vectorstore.bedrock-knowledge-base.search-type=HYBRID ---- == Reranking You can improve search relevance by enabling a Bedrock reranking model: [source,properties] ---- spring.ai.vectorstore.bedrock-knowledge-base.reranking-model-arn=arn:aws:bedrock:us-west-2::foundation-model/amazon.rerank-v1:0 ---- Available reranking models: * Amazon Rerank 1.0 - Available in us-west-2, ap-northeast-1, ca-central-1, eu-central-1 * Cohere Rerank 3.5 - Requires AWS Marketplace subscription == Metadata Filtering You can leverage the generic, portable link:https://docs.spring.io/spring-ai/reference/api/vectordbs.html#_metadata_filters[metadata filters] with the Bedrock Knowledge Base store. For example, you can use the text expression language: [source,java] ---- vectorStore.similaritySearch( SearchRequest.builder() .query("travel policy") .topK(5) .similarityThreshold(0.5) .filterExpression("department == 'HR' && year >= 2024") .build()); ---- or programmatically using the `Filter.Expression` DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch( SearchRequest.builder() .query("travel policy") .topK(5) .filterExpression(b.and( b.eq("department", "HR"), b.gte("year", 2024)).build()) .build()); ---- === Supported Filter Operators [stripes=even] |=== | Spring AI | Bedrock | Description | EQ | equals | Equal to | NE | notEquals | Not equal to | GT | greaterThan | Greater than | GTE | greaterThanOrEquals | Greater than or equal | LT | lessThan | Less than | LTE | lessThanOrEquals | Less than or equal | IN | in | Value in list | NIN | notIn | Value not in list | AND | andAll | Logical AND | OR | orAll | Logical OR | NOT | (negation) | Logical NOT |=== [NOTE] ==== Metadata filtering requires documents in your Knowledge Base to have metadata attributes. For S3 data sources, create `.metadata.json` files alongside your documents. ==== == Manual Configuration If you prefer to configure the vector store manually, you can do so by creating the beans directly. Add this dependency to your project: [source,xml] ---- org.springframework.ai spring-ai-bedrock-knowledgebase-store ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Sample Code [source,java] ---- @Bean public BedrockAgentRuntimeClient bedrockAgentRuntimeClient() { return BedrockAgentRuntimeClient.builder() .region(Region.US_EAST_1) .build(); } @Bean public VectorStore vectorStore(BedrockAgentRuntimeClient client) { return BedrockKnowledgeBaseVectorStore.builder(client, "YOUR_KNOWLEDGE_BASE_ID") .topK(10) .similarityThreshold(0.5) .searchType(SearchType.SEMANTIC) .build(); } ---- Then use the vector store: [source,java] ---- List results = vectorStore.similaritySearch( SearchRequest.builder() .query("What are the company holidays?") .topK(3) .build()); for (Document doc : results) { System.out.println("Content: " + doc.getText()); System.out.println("Score: " + doc.getScore()); System.out.println("Source: " + doc.getMetadata().get("source")); } ---- == Accessing the Native Client The Bedrock Knowledge Base Vector Store provides access to the underlying native client through the `getNativeClient()` method: [source,java] ---- BedrockKnowledgeBaseVectorStore vectorStore = context.getBean(BedrockKnowledgeBaseVectorStore.class); Optional nativeClient = vectorStore.getNativeClient(); if (nativeClient.isPresent()) { BedrockAgentRuntimeClient client = nativeClient.get(); // Use the native client for Bedrock-specific operations } ---- == Limitations * **Read-only**: The `add()` and `delete()` methods throw `UnsupportedOperationException`. Documents are managed through the Knowledge Base's data source sync process. * **HYBRID search**: Only available with OpenSearch-based vector stores. * **Reranking availability**: Model availability varies by AWS region. == Supported Data Sources Bedrock Knowledge Base supports multiple data source types. The source location is included in document metadata: [stripes=even] |=== | Data Source | Metadata Field | Example | S3 | `source` | `s3://bucket/path/document.pdf` | Confluence | `source` | `https://confluence.example.com/page/123` | SharePoint | `source` | `https://sharepoint.example.com/doc/456` | Salesforce | `source` | `https://salesforce.example.com/record/789` | Web Crawler | `source` | `https://example.com/page` | Custom | `source` | Custom document ID |=== ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/chroma.adoc ================================================ = Chroma This section will walk you through setting up the Chroma VectorStore to store document embeddings and perform similarity searches. link: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. == Prerequisites 1. Access to ChromaDB. Compatible with link:https://trychroma.com/signup[Chroma Cloud], or <> in the appendix shows how to set up a DB locally with a Docker container. - For Chroma Cloud: You'll need your API key, tenant name, and database name from your Chroma Cloud dashboard. - For local ChromaDB: No additional configuration required beyond starting the container. 2. `EmbeddingModel` instance to compute the document embeddings. Several options are available: - If required, an API key for the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] to generate the embeddings stored by the `ChromaVectorStore`. On startup, the `ChromaVectorStore` creates the required collection if one is not provisioned already. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the Chroma Vector Store. To enable it, add the following dependency to your project's Maven `pom.xml` file: [source, xml] ---- org.springframework.ai spring-ai-starter-vector-store-chroma ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-vector-store-chroma' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. TIP: Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Maven Central and/or Snapshot Repositories to your build file. The 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. NOTE: this is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default. Additionally, you will need a configured `EmbeddingModel` bean. Refer to the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] section for more information. Here is an example of the needed bean: [source,java] ---- @Bean public EmbeddingModel embeddingModel() { // Can be any other EmbeddingModel implementation. return new OpenAiEmbeddingModel(OpenAiApi.builder().apiKey(System.getenv("OPENAI_API_KEY")).build()); } ---- To connect to Chroma you need to provide access details for your instance. A simple configuration can either be provided via Spring Boot's _application.properties_, [source,properties] ---- # Chroma Vector Store connection properties spring.ai.vectorstore.chroma.client.host= // for Chroma Cloud: api.trychroma.com spring.ai.vectorstore.chroma.client.port= // for Chroma Cloud: 443 spring.ai.vectorstore.chroma.client.key-token= // for Chroma Cloud: use the API key spring.ai.vectorstore.chroma.client.username= spring.ai.vectorstore.chroma.client.password= # Chroma Vector Store tenant and database properties (required for Chroma Cloud) spring.ai.vectorstore.chroma.tenant-name= // default: SpringAiTenant spring.ai.vectorstore.chroma.database-name= // default: SpringAiDatabase # Chroma Vector Store collection properties spring.ai.vectorstore.chroma.initialize-schema= spring.ai.vectorstore.chroma.collection-name= # Chroma Vector Store configuration properties # OpenAI API key if the OpenAI auto-configuration is used. spring.ai.openai.api.key= ---- Please 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. Now you can auto-wire the Chroma Vector Store in your application and use it [source,java] ---- @Autowired VectorStore vectorStore; // ... List documents = List.of( new Document("Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!", Map.of("meta1", "meta1")), new Document("The World is Big and Salvation Lurks Around the Corner"), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("meta2", "meta2"))); // Add the documents vectorStore.add(documents); // Retrieve documents similar to a query List results = this.vectorStore.similaritySearch(SearchRequest.builder().query("Spring").topK(5).build()); ---- === Configuration properties You can use the following properties in your Spring Boot configuration to customize the vector store. [stripes=even] |=== |Property| Description | Default value |`spring.ai.vectorstore.chroma.client.host`| Server connection host | http://localhost[http://localhost] |`spring.ai.vectorstore.chroma.client.port`| Server connection port | `8000` |`spring.ai.vectorstore.chroma.client.key-token`| Access token (if configured) | - |`spring.ai.vectorstore.chroma.client.username`| Access username (if configured) | - |`spring.ai.vectorstore.chroma.client.password`| Access password (if configured) | - |`spring.ai.vectorstore.chroma.tenant-name`| Tenant (required for Chroma Cloud) | `SpringAiTenant` |`spring.ai.vectorstore.chroma.database-name`| Database name (required for Chroma Cloud) | `SpringAiDatabase` |`spring.ai.vectorstore.chroma.collection-name`| Collection name | `SpringAiCollection` |`spring.ai.vectorstore.chroma.initialize-schema`| Whether to initialize the required schema (creates tenant/database/collection if they don't exist) | `false` |=== [NOTE] ==== For ChromaDB secured with link:https://docs.trychroma.com/usage-guide#static-api-token-authentication[Static API Token Authentication] use the `ChromaApi#withKeyToken()` method to set your credentials. Check the `ChromaWhereIT` for an example. For ChromaDB secured with link:https://docs.trychroma.com/usage-guide#basic-authentication[Basic Authentication] use the `ChromaApi#withBasicAuth(, )` method to set your credentials. Check the `BasicAuthChromaWhereIT` for an example. ==== === Chroma Cloud Configuration For Chroma Cloud, you need to provide the tenant and database names from your Chroma Cloud instance. Here's an example configuration: [source,properties] ---- # Chroma Cloud connection spring.ai.vectorstore.chroma.client.host=api.trychroma.com spring.ai.vectorstore.chroma.client.port=443 spring.ai.vectorstore.chroma.client.key-token= # Chroma Cloud tenant and database (required) spring.ai.vectorstore.chroma.tenant-name= spring.ai.vectorstore.chroma.database-name= # Collection configuration spring.ai.vectorstore.chroma.collection-name=my-collection spring.ai.vectorstore.chroma.initialize-schema=true ---- [NOTE] ==== For Chroma Cloud: - The host should be `api.trychroma.com` - The port should be `443` (HTTPS) - You must provide your API key via `key-token` - The tenant and database names must match your Chroma Cloud configuration - Set `initialize-schema=true` to automatically create the collection if it doesn't exist (it won't recreate existing tenant/database) ==== == Metadata filtering You 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. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch( SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression("author in ['john', 'jill'] && article_type == 'blog'").build()); ---- or programmatically using the `Filter.Expression` DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression(b.and( b.in("john", "jill"), b.eq("article_type", "blog")).build()).build()); ---- NOTE: Those (portable) filter expressions get automatically converted into the proprietary Chroma `where` link:https://docs.trychroma.com/usage-guide#using-where-filters[filter expressions]. For example, this portable filter expression: ```sql author in ['john', 'jill'] && article_type == 'blog' ``` is converted into the proprietary Chroma format ```json {"$and":[ {"author": {"$in": ["john", "jill"]}}, {"article_type":{"$eq":"blog"}}] } ``` == Manual Configuration If you prefer to configure the Chroma Vector Store manually, you can do so by creating a `ChromaVectorStore` bean in your Spring Boot application. Add these dependencies to your project: * Chroma VectorStore. [source,xml] ---- org.springframework.ai spring-ai-chroma-store ---- * OpenAI: Required for calculating embeddings. You can use any other embedding model implementation. [source,xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. === Sample Code Create a `RestClient.Builder` instance with proper ChromaDB authorization configurations and Use it to create a `ChromaApi` instance: [source,java] ---- @Bean public RestClient.Builder builder() { return RestClient.builder().requestFactory(new SimpleClientHttpRequestFactory()); } @Bean public ChromaApi chromaApi(RestClient.Builder restClientBuilder) { String chromaUrl = "http://localhost:8000"; ChromaApi chromaApi = new ChromaApi(chromaUrl, restClientBuilder); return chromaApi; } ---- Integrate with OpenAI's embeddings by adding the Spring Boot OpenAI starter to your project. This provides you with an implementation of the Embeddings client: [source,java] ---- @Bean public VectorStore chromaVectorStore(EmbeddingModel embeddingModel, ChromaApi chromaApi) { return ChromaVectorStore.builder(chromaApi, embeddingModel) .tenantName("your-tenant-name") // default: SpringAiTenant .databaseName("your-database-name") // default: SpringAiDatabase .collectionName("TestCollection") .initializeSchema(true) .build(); } ---- In your main code, create some documents: [source,java] ---- List documents = List.of( new Document("Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!", Map.of("meta1", "meta1")), new Document("The World is Big and Salvation Lurks Around the Corner"), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("meta2", "meta2"))); ---- Add the documents to your vector store: [source,java] ---- vectorStore.add(documents); ---- And finally, retrieve documents similar to a query: [source,java] ---- List results = vectorStore.similaritySearch("Spring"); ---- If all goes well, you should retrieve the document containing the text "Spring AI rocks!!". === Run Chroma Locally ```shell docker run -it --rm --name chroma -p 8000:8000 ghcr.io/chroma-core/chroma:1.0.0 ``` Starts a chroma store at ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/coherence.adoc ================================================ == Accessing the Native Client The Coherence Vector Store implementation provides access to the underlying native Coherence client (`Session`) through the `getNativeClient()` method: [source,java] ---- CoherenceVectorStore vectorStore = context.getBean(CoherenceVectorStore.class); Optional nativeClient = vectorStore.getNativeClient(); if (nativeClient.isPresent()) { Session session = nativeClient.get(); // Use the native client for Coherence-specific operations } ---- The native client gives you access to Coherence-specific features and operations that might not be exposed through the `VectorStore` interface. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/couchbase.adoc ================================================ = Couchbase This section will walk you through setting up the `CouchbaseSearchVectorStore` to store document embeddings and perform similarity searches using Couchbase. link:https://docs.couchbase.com/server/current/vector-search/vector-search.html[Couchbase] is a distributed, JSON document database, with all the desired capabilities of a relational DBMS.

[source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-couchbase-store-spring-boot-starter' } ---- NOTE: Couchbase Vector search is only available in starting version 7.6 and Java SDK version 3.6.0" TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. TIP: Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Milestone and/or Snapshot Repositories to your build file. The vector store implementation can initialize the configured bucket, scope, collection and search index for you, with default options, but you must opt-in by specifying the `initializeSchema` boolean in the appropriate constructor. NOTE: This is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default. Please have a look at the list of <> for the vector store to learn about the default values and configuration options. Additionally, you will need a configured `EmbeddingModel` bean. Refer to the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] section for more information. Now you can auto-wire the `CouchbaseSearchVectorStore` as a vector store in your application. [source,java] ---- @Autowired VectorStore vectorStore; // ... List documents = List.of( new Document("Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!", Map.of("meta1", "meta1")), new Document("The World is Big and Salvation Lurks Around the Corner"), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("meta2", "meta2"))); // Add the documents to Qdrant vectorStore.add(documents); // Retrieve documents similar to a query List results = vectorStore.similaritySearch(SearchRequest.query("Spring").withTopK(5)); ---- [[couchbasevector-properties]] === Configuration Properties To connect to Couchbase and use the `CouchbaseSearchVectorStore`, you need to provide access details for your instance. Configuration can be provided via Spring Boot's `application.properties`: [source,properties] ---- spring.ai.openai.api-key= spring.couchbase.connection-string= spring.couchbase.username= spring.couchbase.password= ---- If you prefer to use environment variables for sensitive information like passwords or API keys, you have multiple options: ==== Option 1: Using Spring Expression Language (SpEL) You can use custom environment variable names and reference them in your application configuration using SpEL: [source,yaml] ---- # In application.yml spring: ai: openai: api-key: ${OPENAI_API_KEY} couchbase: connection-string: ${COUCHBASE_CONN_STRING} username: ${COUCHBASE_USER} password: ${COUCHBASE_PASSWORD} ---- [source,bash] ---- # In your environment or .env file export OPENAI_API_KEY= export COUCHBASE_CONN_STRING= export COUCHBASE_USER= export COUCHBASE_PASSWORD= ---- ==== Option 2: Accessing Environment Variables Programmatically Alternatively, you can access environment variables in your Java code: [source,java] ---- String apiKey = System.getenv("OPENAI_API_KEY"); ---- This approach gives you flexibility in naming your environment variables while keeping sensitive information out of your application configuration files. NOTE: If you choose to create a shell script for ease in future work, be sure to run it prior to starting your application by "sourcing" the file, i.e. `source .sh`. Spring Boot's auto-configuration feature for the Couchbase Cluster will create a bean instance that will be used by the `CouchbaseSearchVectorStore`. The Spring Boot properties starting with `spring.couchbase.*` are used to configure the Couchbase cluster instance: |=== |Property | Description | Default Value | `spring.couchbase.connection-string` | A couchbase connection string | `couchbase://localhost` | `spring.couchbase.password` | Password for authentication with Couchbase. | - | `spring.couchbase.username` | Username for authentication with Couchbase.| - | `spring.couchbase.env.io.minEndpoints` | Minimum number of sockets per node.| 1 | `spring.couchbase.env.io.maxEndpoints` | Maximum number of sockets per node.| 12 | `spring.couchbase.env.io.idleHttpConnectionTimeout` | Length of time an HTTP connection may remain idle before it is closed and removed from the pool.| 1s | `spring.couchbase.env.ssl.enabled` | Whether to enable SSL support. Enabled automatically if a "bundle" is provided unless specified otherwise.| - | `spring.couchbase.env.ssl.bundle` | SSL bundle name.| - | `spring.couchbase.env.timeouts.connect` | Bucket connect timeout.| 10s | `spring.couchbase.env.timeouts.disconnect` | Bucket disconnect timeout.| 10s | `spring.couchbase.env.timeouts.key-value` | Timeout for operations on a specific key-value.| 2500ms | `spring.couchbase.env.timeouts.key-value` | Timeout for operations on a specific key-value with a durability level.| 10s | `spring.couchbase.env.timeouts.key-value-durable` | Timeout for operations on a specific key-value with a durability level.| 10s | `spring.couchbase.env.timeouts.query` | SQL++ query operations timeout.| 75s | `spring.couchbase.env.timeouts.view` | Regular and geospatial view operations timeout.| 75s | `spring.couchbase.env.timeouts.search` | Timeout for the search service.| 75s | `spring.couchbase.env.timeouts.analytics` | Timeout for the analytics service.| 75s | `spring.couchbase.env.timeouts.management` | Timeout for the management operations.| 75s |=== Properties starting with the `spring.ai.vectorstore.couchbase.*` prefix are used to configure `CouchbaseSearchVectorStore`. |=== |Property | Description | Default Value |`spring.ai.vectorstore.couchbase.index-name` | The name of the index to store the vectors. | spring-ai-document-index |`spring.ai.vectorstore.couchbase.bucket-name` | The name of the Couchbase Bucket, parent of the scope. | default |`spring.ai.vectorstore.couchbase.scope-name` |The name of the Couchbase scope, parent of the collection. Search queries will be executed in the scope context.| _default_ |`spring.ai.vectorstore.couchbase.collection-name` | The name of the Couchbase collection to store the Documents. | _default_ |`spring.ai.vectorstore.couchbase.dimensions` | The number of dimensions in the vector. | 1536 |`spring.ai.vectorstore.couchbase.similarity` | The similarity function to use. | `dot_product` |`spring.ai.vectorstore.couchbase.optimization` | The similarity function to use. | `recall` |`spring.ai.vectorstore.couchbase.initialize-schema`| whether to initialize the required schema | `false` |=== The following similarity functions are available: * l2_norm * dot_product The following index optimizations are available: * recall * latency More details about each in the https://docs.couchbase.com/server/current/search/child-field-options-reference.html[Couchbase Documentation] on vector searches. == Metadata Filtering You can leverage the generic, portable link:https://docs.spring.io/spring-ai/reference/api/vectordbs.html#_metadata_filters[metadata filters] with the Couchbase store. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch( SearchRequest.defaults() .query("The World") .topK(TOP_K) .filterExpression("author in ['john', 'jill'] && article_type == 'blog'")); ---- or programmatically using the `Filter.Expression` DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch(SearchRequest.defaults() .query("The World") .topK(TOP_K) .filterExpression(b.and( b.in("author","john", "jill"), b.eq("article_type", "blog")).build())); ---- NOTE: These filter expressions are converted into the equivalent Couchbase SQL++ filters. == Manual Configuration Instead of using the Spring Boot auto-configuration, you can manually configure the Couchbase vector store. For this you need to add the `spring-ai-couchbase-store` to your project: [source,xml] ---- org.springframework.ai spring-ai-couchbase-store ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-couchbase-store' } ---- Create a Couchbase `Cluster` bean. Read the link:https://docs.couchbase.com/java-sdk/current/hello-world/start-using-sdk.html[Couchbase Documentation] for more in-depth information about the configuration of a custom Cluster instance. [source,java] ---- @Bean public Cluster cluster() { return Cluster.connect("couchbase://localhost", "username", "password"); } ---- and then create the `CouchbaseSearchVectorStore` bean using the builder pattern: [source,java] ---- @Bean public VectorStore couchbaseSearchVectorStore(Cluster cluster, EmbeddingModel embeddingModel, Boolean initializeSchema) { return CouchbaseSearchVectorStore .builder(cluster, embeddingModel) .bucketName("test") .scopeName("test") .collectionName("test") .initializeSchema(initializeSchema) .build(); } // This can be any EmbeddingModel implementation. @Bean public EmbeddingModel embeddingModel() { return new OpenAiEmbeddingModel(OpenAiApi.builder().apiKey(this.openaiKey).build()); } ---- == Limitations NOTE: It is mandatory to have the following Couchbase services activated: Data, Query, Index, Search. While Data and Search could be enough, Query and Index are necessary to support the complete metadata filtering mechanism. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/elasticsearch.adoc ================================================ = Elasticsearch This section walks you through setting up the Elasticsearch `VectorStore` to store document embeddings and perform similarity searches. link:https://www.elastic.co/elasticsearch[Elasticsearch] is an open source search and analytics engine based on the Apache Lucene library. == Prerequisites A running Elasticsearch instance. The following options are available: * link:https://hub.docker.com/_/elasticsearch/[Docker] * link:https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html#elasticsearch-install-packages[Self-Managed Elasticsearch] * link:https://www.elastic.co/cloud/elasticsearch-service/signup?page=docs&placement=docs-body[Elastic Cloud] == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the Elasticsearch Vector Store. To enable it, add the following dependency to your project's Maven `pom.xml` or Gradle `build.gradle` build files: [tabs] ====== Maven:: + [source,xml] ---- org.springframework.ai spring-ai-starter-vector-store-elasticsearch ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-vector-store-elasticsearch' } ---- ====== [NOTE] -- For spring-boot versions pre 3.3.0 it's necessary to explicitly add the elasticsearch-java dependency with version > 8.13.3, otherwise the older version used will be incompatible with the queries performed: [tabs] ====== Maven:: + [source,xml] ---- co.elastic.clients elasticsearch-java 8.13.3 ---- Gradle:: + [source,groovy] ---- dependencies { implementation 'co.elastic.clients:elasticsearch-java:8.13.3' } ---- ====== -- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. TIP: Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Maven Central and/or Snapshot Repositories to your build file. The 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. Alternatively you can opt-out the initialization and create the index manually using the Elasticsearch client, which can be useful if the index needs advanced mapping or additional configuration. NOTE: this is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default. Please have a look at the list of <> for the vector store to learn about the default values and configuration options. These properties can be also set by configuring the `ElasticsearchVectorStoreOptions` bean. Additionally, you will need a configured `EmbeddingModel` bean. Refer to the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] section for more information. Now you can auto-wire the `ElasticsearchVectorStore` as a vector store in your application. [source,java] ---- @Autowired VectorStore vectorStore; // ... List documents = List.of( new Document("Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!", Map.of("meta1", "meta1")), new Document("The World is Big and Salvation Lurks Around the Corner"), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("meta2", "meta2"))); // Add the documents to Elasticsearch vectorStore.add(documents); // Retrieve documents similar to a query List results = this.vectorStore.similaritySearch(SearchRequest.builder().query("Spring").topK(5).build()); ---- [[elasticsearchvector-properties]] === Configuration Properties To connect to Elasticsearch and use the `ElasticsearchVectorStore`, you need to provide access details for your instance. A simple configuration can either be provided via Spring Boot's `application.yml`, [source,yaml] ---- spring: elasticsearch: uris: username: password: ai: vectorstore: elasticsearch: initialize-schema: true index-name: custom-index dimensions: 1536 similarity: cosine ---- The Spring Boot properties starting with `spring.elasticsearch.*` are used to configure the Elasticsearch client: [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value | `spring.elasticsearch.connection-timeout` | Connection timeout used when communicating with Elasticsearch. | `1s` | `spring.elasticsearch.password` | Password for authentication with Elasticsearch. | - | `spring.elasticsearch.username` | Username for authentication with Elasticsearch.| - | `spring.elasticsearch.uris` | Comma-separated list of the Elasticsearch instances to use. | `+http://localhost:9200+` | `spring.elasticsearch.path-prefix` | Prefix added to the path of every request sent to Elasticsearch. | - | `spring.elasticsearch.restclient.sniffer.delay-after-failure` | Delay of a sniff execution scheduled after a failure.| `1m` | `spring.elasticsearch.restclient.sniffer.interval` | Interval between consecutive ordinary sniff executions. | `5m` | `spring.elasticsearch.restclient.ssl.bundle` | SSL bundle name. | - | `spring.elasticsearch.socket-keep-alive` | Whether to enable socket keep alive between client and Elasticsearch. | `false` | `spring.elasticsearch.socket-timeout` | Socket timeout used when communicating with Elasticsearch. | `30s` |=== Properties starting with `spring.ai.vectorstore.elasticsearch.*` are used to configure the `ElasticsearchVectorStore`: [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value |`spring.ai.vectorstore.elasticsearch.initialize-schema`| Whether to initialize the required schema | `false` |`spring.ai.vectorstore.elasticsearch.index-name` | The name of the index to store the vectors | `spring-ai-document-index` |`spring.ai.vectorstore.elasticsearch.dimensions` | The number of dimensions in the vector | `1536` |`spring.ai.vectorstore.elasticsearch.similarity` | The similarity function to use | `cosine` |`spring.ai.vectorstore.elasticsearch.embedding-field-name` | The name of the vector field to search against | `embedding` |=== The following similarity functions are available: * `cosine` - Default, suitable for most use cases. Measures cosine similarity between vectors. * `l2_norm` - Euclidean distance between vectors. Lower values indicate higher similarity. * `dot_product` - Best performance for normalized vectors (e.g., OpenAI embeddings). More details about each in the https://www.elastic.co/guide/en/elasticsearch/reference/master/dense-vector.html#dense-vector-params[Elasticsearch Documentation] on dense vectors. == Metadata Filtering You can leverage the generic, portable xref:api/vectordbs.adoc#metadata-filters[metadata filters] with Elasticsearch as well. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression("author in ['john', 'jill'] && 'article_type' == 'blog'").build()); ---- or programmatically using the `Filter.Expression` DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression(b.and( b.in("author", "john", "jill"), b.eq("article_type", "blog")).build()).build()); ---- NOTE: Those (portable) filter expressions get automatically converted into the proprietary Elasticsearch link:https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html[Query string query]. For example, this portable filter expression: [source,sql] ---- author in ['john', 'jill'] && 'article_type' == 'blog' ---- is converted into the proprietary Elasticsearch filter format: [source,text] ---- (metadata.author:john OR jill) AND metadata.article_type:blog ---- == Manual Configuration Instead of using the Spring Boot auto-configuration, you can manually configure the Elasticsearch vector store. For this you need to add the `spring-ai-elasticsearch-store` to your project: [source,xml] ---- org.springframework.ai spring-ai-elasticsearch-store ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-elasticsearch-store' } ---- Create an Elasticsearch `RestClient` bean. Read the link:https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/java-rest-low-usage-initialization.html[Elasticsearch Documentation] for more in-depth information about the configuration of a custom RestClient. [source,java] ---- @Bean public RestClient restClient() { return RestClient.builder(new HttpHost("", 9200, "http")) .setDefaultHeaders(new Header[]{ new BasicHeader("Authorization", "Basic ") }) .build(); } ---- Then create the `ElasticsearchVectorStore` bean using the builder pattern: [source,java] ---- @Bean public VectorStore vectorStore(RestClient restClient, EmbeddingModel embeddingModel) { ElasticsearchVectorStoreOptions options = new ElasticsearchVectorStoreOptions(); options.setIndexName("custom-index"); // Optional: defaults to "spring-ai-document-index" options.setSimilarity(COSINE); // Optional: defaults to COSINE options.setDimensions(1536); // Optional: defaults to model dimensions or 1536 return ElasticsearchVectorStore.builder(restClient, embeddingModel) .options(options) // Optional: use custom options .initializeSchema(true) // Optional: defaults to false .batchingStrategy(new TokenCountBatchingStrategy()) // Optional: defaults to TokenCountBatchingStrategy .build(); } // This can be any EmbeddingModel implementation @Bean public EmbeddingModel embeddingModel() { return new OpenAiEmbeddingModel(new OpenAiApi(System.getenv("OPENAI_API_KEY"))); } ---- == Accessing the Native Client The Elasticsearch Vector Store implementation provides access to the underlying native Elasticsearch client (`ElasticsearchClient`) through the `getNativeClient()` method: [source,java] ---- ElasticsearchVectorStore vectorStore = context.getBean(ElasticsearchVectorStore.class); Optional nativeClient = vectorStore.getNativeClient(); if (nativeClient.isPresent()) { ElasticsearchClient client = nativeClient.get(); // Use the native client for Elasticsearch-specific operations } ---- The native client gives you access to Elasticsearch-specific features and operations that might not be exposed through the `VectorStore` interface. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/gemfire.adoc ================================================ = GemFire Vector Store This section walks you through setting up the `GemFireVectorStore` to store document embeddings and perform similarity searches. link:https://tanzu.vmware.com/gemfire[GemFire] is a distributed, in-memory, key-value store performing read and write operations at blazingly fast speeds. It offers highly available parallel message queues, continuous availability, and an event-driven architecture you can scale dynamically without downtime. As your data size requirements increase to support high-performance, real-time apps, GemFire can easily scale linearly. link:https://docs.vmware.com/en/VMware-GemFire-VectorDB/1.0/gemfire-vectordb/overview.html[GemFire VectorDB] extends GemFire's capabilities, serving as a versatile vector database that efficiently stores, retrieves, and performs vector similarity searches. == Prerequisites 1. A GemFire cluster with the GemFire VectorDB extension enabled - link:https://docs.vmware.com/en/VMware-GemFire-VectorDB/1.0/gemfire-vectordb/install.html[Install GemFire VectorDB extension] 2. An `EmbeddingModel` bean to compute the document embeddings. Refer to the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] section for more information. An option that runs locally on your machine is xref:api/embeddings/onnx.adoc[ONNX] and the all-MiniLM-L6-v2 Sentence Transformers. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Add the GemFire VectorStore Spring Boot starter to you project's Maven build file `pom.xml`: [source, xml] ---- org.springframework.ai spring-ai-starter-vector-store-gemfire ---- or to your Gradle `build.gradle` file [source, xml] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-vector-store-gemfire' } ---- === Configuration properties You can use the following properties in your Spring Boot configuration to further configure the `GemFireVectorStore`.

Spring AI rocks!!", Map.of("country", "UK", "year", 2020)), new Document("The World is Big and Salvation Lurks Around the Corner", Map.of()), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("country", "NL", "year", 2023))); ---- - Add the documents to the vector store: [source,java] ---- vectorStore.add(documents); ---- - And to retrieve documents using similarity search: [source,java] ---- List results = vectorStore.similaritySearch( SearchRequest.builder().query("Spring").topK(5).build()); ---- You should retrieve the document containing the text "Spring AI rocks!!". You can also limit the number of results using a similarity threshold: [source,java] ---- List results = vectorStore.similaritySearch( SearchRequest.builder().query("Spring").topK(5) .similarityThreshold(0.5d).build()); ---- == Metadata Filtering You can leverage the generic, portable xref:api/vectordbs.adoc#metadata-filters[metadata filters] with GemFire VectorStore as well. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(5) .similarityThreshold(0.7) .filterExpression("country == 'BG' && year >= 2020").build()); ---- or programmatically using the `Filter.Expression` DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(5) .similarityThreshold(0.7) .filterExpression(b.and( b.eq("country", "BG"), b.gte("year", 2020)).build()).build()); ---- NOTE: Those (portable) filter expressions get automatically converted into the proprietary GemFire VectorDB query format. For example, this portable filter expression: [source,sql] ---- country == 'BG' && year >= 2020 ---- is converted into the proprietary GemFire VectorDB filter format: ---- country:BG AND year:[2020 TO *] ---- The GemFire VectorStore supports a wide range of filter operations: * **Equality**: `country == 'BG'` → `country:BG` * **Inequality**: `city != 'Sofia'` → `city: NOT Sofia` * **Greater Than**: `year > 2020` → `year:{2020 TO *]` * **Greater Than or Equal**: `year >= 2020` → `year:[2020 TO *]` * **Less Than**: `year < 2025` → `year:[* TO 2025}` * **Less Than or Equal**: `year <= 2025` → `year:[* TO 2025]` * **IN**: `country in ['BG', 'NL']` → `country:(BG OR NL)` * **NOT IN**: `country nin ['BG', 'NL']` → `NOT country:(BG OR NL)` * **AND/OR**: Logical operators for combining conditions * **Grouping**: Use parentheses for complex expressions * **Date Filtering**: Date values in ISO 8601 format (e.g., `2024-01-07T14:29:12Z`) [IMPORTANT] ==== To use metadata filtering with GemFire VectorStore, you must specify the metadata fields that can be filtered when creating the vector store. This is done using the `fields` parameter in the builder: [source,java] ---- GemFireVectorStore.builder(embeddingModel) .fields(new String[] {"country", "year", "activationDate"}) .build(); ---- Or via configuration properties: [source,properties] ---- spring.ai.vectorstore.gemfire.fields=country,year,activationDate ---- ==== ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/hana.adoc ================================================ = SAP HANA Cloud == Prerequisites * You need a SAP HANA Cloud vector engine account - Refer xref:api/vectordbs/hanadb-provision-a-trial-account.adoc[SAP HANA Cloud vector engine - provision a trial account] guide to create a trial account. * If required, an API key for the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] to generate the embeddings stored by the vector store. == Auto-configuration Spring AI does not provide a dedicated module for SAP Hana vector store. Users are expected to provide their own configuration in the applications using the standard vector store module for SAP Hana vector store in Spring AI - `spring-ai-hanadb-store`.

It provides efficient vector similarity search capabilities using vector indexes, supporting both cosine similarity and Euclidean distance metrics. == Prerequisites * A running MariaDB (11.7+) instance. The following options are available: ** link:https://hub.docker.com/_/mariadb[Docker] image ** link:https://mariadb.org/download/[MariaDB Server] ** link:https://mariadb.com/products/skysql/[MariaDB SkySQL] * If required, an API key for the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] to generate the embeddings stored by the `MariaDBVectorStore`. == Auto-Configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the MariaDB Vector Store. To enable it, add the following dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-starter-vector-store-mariadb ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-vector-store-mariadb' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. The 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. NOTE: This is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default. Additionally, you will need a configured `EmbeddingModel` bean. Refer to the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] section for more information. For example, to use the xref:api/embeddings/openai-embeddings.adoc[OpenAI EmbeddingModel], add the following dependency: [source,xml] ---- org.springframework.ai spring-ai-starter-model-openai ---- TIP: Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Maven Central and/or Snapshot Repositories to your build file. Now you can auto-wire the `MariaDBVectorStore` in your application: [source,java] ---- @Autowired VectorStore vectorStore; // ... List documents = List.of( new Document("Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!", Map.of("meta1", "meta1")), new Document("The World is Big and Salvation Lurks Around the Corner"), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("meta2", "meta2"))); // Add the documents to MariaDB vectorStore.add(documents); // Retrieve documents similar to a query List results = vectorStore.similaritySearch(SearchRequest.builder().query("Spring").topK(5).build()); ---- [[mariadbvector-properties]] === Configuration Properties To connect to MariaDB and use the `MariaDBVectorStore`, you need to provide access details for your instance. A simple configuration can be provided via Spring Boot's `application.yml`: [source,yaml] ---- spring: datasource: url: jdbc:mariadb://localhost/db username: myUser password: myPassword ai: vectorstore: mariadb: initialize-schema: true distance-type: COSINE dimensions: 1536 ---- TIP: 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] or link:https://docs.spring.io/spring-boot/reference/features/dev-services.html#features.dev-services.testcontainers[Testcontainers], you don't need to configure URL, username and password since they are autoconfigured by Spring Boot. Properties starting with `spring.ai.vectorstore.mariadb.*` are used to configure the `MariaDBVectorStore`: [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value |`spring.ai.vectorstore.mariadb.initialize-schema`| Whether to initialize the required schema | `false` |`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` |`spring.ai.vectorstore.mariadb.dimensions`| Embeddings dimension. If not specified explicitly, will retrieve dimensions from the provided `EmbeddingModel`. | `1536` |`spring.ai.vectorstore.mariadb.remove-existing-vector-store-table` | Deletes the existing vector store table on startup. | `false` |`spring.ai.vectorstore.mariadb.schema-name` | Vector store schema name | `null` |`spring.ai.vectorstore.mariadb.table-name` | Vector store table name | `vector_store` |`spring.ai.vectorstore.mariadb.schema-validation` | Enables schema and table name validation to ensure they are valid and existing objects. | `false` |=== TIP: If you configure a custom schema and/or table name, consider enabling schema validation by setting `spring.ai.vectorstore.mariadb.schema-validation=true`. This ensures the correctness of the names and reduces the risk of SQL injection attacks. == Manual Configuration Instead of using the Spring Boot auto-configuration, you can manually configure the MariaDB vector store. For this you need to add the following dependencies to your project: [source,xml] ---- org.springframework.boot spring-boot-starter-jdbc org.mariadb.jdbc mariadb-java-client runtime org.springframework.ai spring-ai-mariadb-store ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Then create the `MariaDBVectorStore` bean using the builder pattern: [source,java] ---- @Bean public VectorStore vectorStore(JdbcTemplate jdbcTemplate, EmbeddingModel embeddingModel) { return MariaDBVectorStore.builder(jdbcTemplate, embeddingModel) .dimensions(1536) // Optional: defaults to 1536 .distanceType(MariaDBDistanceType.COSINE) // Optional: defaults to COSINE .schemaName("mydb") // Optional: defaults to null .vectorTableName("custom_vectors") // Optional: defaults to "vector_store" .contentFieldName("text") // Optional: defaults to "content" .embeddingFieldName("embedding") // Optional: defaults to "embedding" .idFieldName("doc_id") // Optional: defaults to "id" .metadataFieldName("meta") // Optional: defaults to "metadata" .initializeSchema(true) // Optional: defaults to false .schemaValidation(true) // Optional: defaults to false .removeExistingVectorStoreTable(false) // Optional: defaults to false .maxDocumentBatchSize(10000) // Optional: defaults to 10000 .build(); } // This can be any EmbeddingModel implementation @Bean public EmbeddingModel embeddingModel() { return new OpenAiEmbeddingModel(new OpenAiApi(System.getenv("OPENAI_API_KEY"))); } ---- == Metadata Filtering You can leverage the generic, portable xref:api/vectordbs.adoc#metadata-filters[metadata filters] with MariaDB Vector store. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch( SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression("author in ['john', 'jill'] && article_type == 'blog'").build()); ---- or programmatically using the `Filter.Expression` DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression(b.and( b.in("author", "john", "jill"), b.eq("article_type", "blog")).build()).build()); ---- NOTE: These filter expressions are automatically converted into the equivalent MariaDB JSON path expressions. == Similarity Scores The MariaDB Vector Store automatically calculates similarity scores for documents returned from similarity searches. These scores provide a normalized measure of how closely each document matches your search query. === Score Calculation Similarity scores are calculated using the formula `score = 1.0 - distance`, where: * Score: A value between `0.0` and `1.0`, where `1.0` indicates perfect similarity and `0.0` indicates no similarity * Distance: The raw distance value calculated using the configured distance type (`COSINE` or `EUCLIDEAN`) This means that documents with smaller distances (more similar) will have higher scores, making the results more intuitive to interpret. === Accessing Scores You can access the similarity score for each document through the `getScore()` method: [source,java] ---- List results = vectorStore.similaritySearch( SearchRequest.builder() .query("Spring AI") .topK(5) .build()); for (Document doc : results) { double score = doc.getScore(); // Value between 0.0 and 1.0 System.out.println("Document: " + doc.getText()); System.out.println("Similarity Score: " + score); } ---- === Search Results Ordering Search results are automatically ordered by similarity score in descending order (highest score first). This ensures that the most relevant documents appear at the top of your results. === Distance Metadata In addition to the similarity score, the raw distance value is still available in the document metadata: [source,java] ---- for (Document doc : results) { double score = doc.getScore(); float distance = (Float) doc.getMetadata().get("distance"); System.out.println("Score: " + score + ", Distance: " + distance); } ---- === Similarity Threshold When using similarity thresholds in your search requests, specify the threshold as a score value (`0.0` to `1.0`) rather than a distance: [source,java] ---- List results = vectorStore.similaritySearch( SearchRequest.builder() .query("Spring AI") .topK(10) .similarityThreshold(0.8) // Only return documents with score >= 0.8 .build()); ---- This makes threshold values consistent and intuitive - higher values mean more restrictive searches that only return highly similar documents. == Accessing the Native Client The MariaDB Vector Store implementation provides access to the underlying native JDBC client (`JdbcTemplate`) through the `getNativeClient()` method: [source,java] ---- MariaDBVectorStore vectorStore = context.getBean(MariaDBVectorStore.class); Optional nativeClient = vectorStore.getNativeClient(); if (nativeClient.isPresent()) { JdbcTemplate jdbc = nativeClient.get(); // Use the native client for MariaDB-specific operations } ---- The native client gives you access to MariaDB-specific features and operations that might not be exposed through the `VectorStore` interface. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/milvus.adoc ================================================ = Milvus link:https://milvus.io/[Milvus] is an open-source vector database that has garnered significant attention in the fields of data science and machine learning. One of its standout features lies in its robust support for vector indexing and querying. Milvus employs state-of-the-art, cutting-edge algorithms to accelerate the search process, making it exceptionally efficient at retrieving similar vectors, even when handling extensive datasets. == Prerequisites * A running Milvus instance. The following options are available: ** link:https://milvus.io/docs/install_standalone-docker.md[Milvus Standalone]: Docker, Operator, Helm,DEB/RPM, Docker Compose. ** link:https://milvus.io/docs/install_cluster-milvusoperator.md[Milvus Cluster]: Operator, Helm. * If required, an API key for the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] to generate the embeddings stored by the `MilvusVectorStore`. == Dependencies [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Then add the Milvus VectorStore boot starter dependency to your project: [source,xml] ---- org.springframework.ai spring-ai-starter-vector-store-milvus ---- or to your Gradle `build.gradle` build file. [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-vector-store-milvus' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Maven Central and/or Snapshot Repositories to your build file. The 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. NOTE: this is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default. The Vector Store, also requires an `EmbeddingModel` instance to calculate embeddings for the documents. You can pick one of the available xref:api/embeddings.adoc#available-implementations[EmbeddingModel Implementations]. To connect to and configure the `MilvusVectorStore`, you need to provide access details for your instance. A simple configuration can either be provided via Spring Boot's `application.yml` [yml] ---- spring: ai: vectorstore: milvus: client: host: "localhost" port: 19530 username: "root" password: "milvus" databaseName: "default" collectionName: "vector_store" embeddingDimension: 1536 indexType: IVF_FLAT metricType: COSINE ---- TIP: Check the list of xref:#milvus-properties[configuration parameters] to learn about the default values and configuration options. Now you can Auto-wire the Milvus Vector Store in your application and use it [source,java] ---- @Autowired VectorStore vectorStore; // ... List documents = List.of( new Document("Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!", Map.of("meta1", "meta1")), new Document("The World is Big and Salvation Lurks Around the Corner"), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("meta2", "meta2"))); // Add the documents to Milvus Vector Store vectorStore.add(documents); // Retrieve documents similar to a query List results = this.vectorStore.similaritySearch(SearchRequest.builder().query("Spring").topK(5).build()); ---- === Manual Configuration Instead of using the Spring Boot auto-configuration, you can manually configure the `MilvusVectorStore`. To add the following dependencies to your project: [source,xml] ---- org.springframework.ai spring-ai-milvus-store ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. To configure MilvusVectorStore in your application, you can use the following setup: [source,java] ---- @Bean public VectorStore vectorStore(MilvusServiceClient milvusClient, EmbeddingModel embeddingModel) { return MilvusVectorStore.builder(milvusClient, embeddingModel) .collectionName("test_vector_store") .databaseName("default") .indexType(IndexType.IVF_FLAT) .metricType(MetricType.COSINE) .batchingStrategy(new TokenCountBatchingStrategy()) .initializeSchema(true) .build(); } @Bean public MilvusServiceClient milvusClient() { return new MilvusServiceClient(ConnectParam.newBuilder() .withAuthorization("minioadmin", "minioadmin") .withUri(milvusContainer.getEndpoint()) .build()); } ---- == Metadata filtering You can leverage the generic, portable link:https://docs.spring.io/spring-ai/reference/api/vectordbs.html#_metadata_filters[metadata filters] with the Milvus store. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch( SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression("author in ['john', 'jill'] && article_type == 'blog'").build()); ---- or programmatically using the `Filter.Expression` DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(TOP_K) .similarityThreshold(SIMILARITY_THRESHOLD) .filterExpression(b.and( b.in("author","john", "jill"), b.eq("article_type", "blog")).build()).build()); ---- NOTE: These filter expressions are converted into the equivalent Milvus filters. == Using MilvusSearchRequest MilvusSearchRequest extends SearchRequest, allowing you to use Milvus-specific search parameters such as native expressions and search parameter JSON. [source,java] ---- MilvusSearchRequest request = MilvusSearchRequest.milvusBuilder() .query("sample query") .topK(5) .similarityThreshold(0.7) .nativeExpression("metadata[\"age\"] > 30") // Overrides filterExpression if both are set .filterExpression("age <= 30") // Ignored if nativeExpression is set .searchParamsJson("{\"nprobe\":128}") .build(); List results = vectorStore.similaritySearch(request); ---- This allows greater flexibility when using Milvus-specific search features. == Importance of `nativeExpression` and `searchParamsJson` in `MilvusSearchRequest` These two parameters enhance Milvus search precision and ensure optimal query performance: *nativeExpression*: Enables additional filtering capabilities using Milvus' native filtering expressions. https://milvus.io/docs/boolean.md[Milvus Filtering] Example: [source,java] ---- MilvusSearchRequest request = MilvusSearchRequest.milvusBuilder() .query("sample query") .topK(5) .nativeExpression("metadata['category'] == 'science'") .build(); ---- *searchParamsJson*: Essential for tuning search behavior when using IVF_FLAT, Milvus' default index. https://milvus.io/docs/index.md?tab=floating[Milvus Vector Index] By default, `IVF_FLAT` requires `nprobe` to be set for accurate results. If not specified, `nprobe` defaults to `1`, which can lead to poor recall or even zero search results. Example: [source,java] ---- MilvusSearchRequest request = MilvusSearchRequest.milvusBuilder() .query("sample query") .topK(5) .searchParamsJson("{\"nprobe\":128}") .build(); ---- Using `nativeExpression` ensures advanced filtering, while `searchParamsJson` prevents ineffective searches caused by a low default `nprobe` value. [[milvus-properties]] == Milvus VectorStore properties You can use the following properties in your Spring Boot configuration to customize the Milvus vector store.

Atlas supports native Vector Search and full text search on your MongoDB document data. https://www.mongodb.com/products/platform/atlas-vector-search[MongoDB Atlas Vector Search] allows you to store your embeddings in MongoDB documents, create vector search indexes, and perform KNN searches with an approximate nearest neighbor algorithm (Hierarchical Navigable Small Worlds). You can use the `$vectorSearch` aggregation operator in a MongoDB aggregation stage to perform a search on your vector embeddings. == Prerequisites * An Atlas cluster running MongoDB version 6.0.11, 7.0.2, or later. To get started with MongoDB Atlas, you can follow the instructions https://www.mongodb.com/docs/atlas/getting-started/[here]. Ensure that your IP address is included in your Atlas project's https://www.mongodb.com/docs/atlas/security/ip-access-list/#std-label-access-list[access list]. * A running MongoDB Atlas instance with Vector Search enabled * Collection with vector search index configured * Collection schema with id (string), content (string), metadata (document), and embedding (vector) fields * Proper access permissions for index and collection operations == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the MongoDB Atlas Vector Store. To enable it, add the following dependency to your project's Maven `pom.xml` file: [source,xml] ---- org.springframework.ai spring-ai-starter-vector-store-mongodb-atlas ---- or to your Gradle `build.gradle` build file: [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-starter-vector-store-mongodb-atlas' } ---- TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file. TIP: Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Maven Central and/or Snapshot Repositories to your build file. The vector store implementation can initialize the requisite schema for you, but you must opt-in by setting `spring.ai.vectorstore.mongodb.initialize-schema=true` in the `application.properties` file. Alternatively you can opt-out the initialization and create the index manually using the MongoDB Atlas UI, Atlas Administration API, or Atlas CLI, which can be useful if the index needs advanced mapping or additional configuration. NOTE: this is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default. Please have a look at the list of <> for the vector store to learn about the default values and configuration options. Additionally, you will need a configured `EmbeddingModel` bean. Refer to the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] section for more information. Now you can auto-wire the `MongoDBAtlasVectorStore` as a vector store in your application: [source,java] ---- @Autowired VectorStore vectorStore; // ... List documents = List.of( new Document("Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!", Map.of("meta1", "meta1")), new Document("The World is Big and Salvation Lurks Around the Corner"), new Document("You walk forward facing the past and you turn back toward the future.", Map.of("meta2", "meta2"))); // Add the documents to MongoDB Atlas vectorStore.add(documents); // Retrieve documents similar to a query List results = vectorStore.similaritySearch(SearchRequest.builder().query("Spring").topK(5).build()); ---- [[mongodbvector-properties]] === Configuration Properties To connect to MongoDB Atlas and use the `MongoDBAtlasVectorStore`, you need to provide access details for your instance. A simple configuration can be provided via Spring Boot's `application.yml`: [source,yaml] ---- spring: data: mongodb: uri: database: ai: vectorstore: mongodb: initialize-schema: true collection-name: custom_vector_store index-name: custom_vector_index path-name: custom_embedding metadata-fields-to-filter: author,year ---- Properties starting with `spring.ai.vectorstore.mongodb.*` are used to configure the `MongoDBAtlasVectorStore`: [cols="2,5,1",stripes=even] |=== |Property | Description | Default Value |`spring.ai.vectorstore.mongodb.initialize-schema`| Whether to initialize the required schema | `false` |`spring.ai.vectorstore.mongodb.collection-name` | The name of the collection to store the vectors | `vector_store` |`spring.ai.vectorstore.mongodb.index-name` | The name of the vector search index | `vector_index` |`spring.ai.vectorstore.mongodb.path-name` | The path where vectors are stored | `embedding` |`spring.ai.vectorstore.mongodb.metadata-fields-to-filter` | Comma-separated list of metadata fields that can be used for filtering | empty list |=== == Manual Configuration Instead of using the Spring Boot auto-configuration, you can manually configure the MongoDB Atlas vector store. For this you need to add the `spring-ai-mongodb-atlas-store` to your project: [source,xml] ---- org.springframework.ai spring-ai-mongodb-atlas-store ---- or to your Gradle `build.gradle` build file: [source,groovy] ---- dependencies { implementation 'org.springframework.ai:spring-ai-mongodb-atlas-store' } ---- Create a `MongoTemplate` bean: [source,java] ---- @Bean public MongoTemplate mongoTemplate() { return new MongoTemplate(MongoClients.create(""), ""); } ---- Then create the `MongoDBAtlasVectorStore` bean using the builder pattern: [source,java] ---- @Bean public VectorStore vectorStore(MongoTemplate mongoTemplate, EmbeddingModel embeddingModel) { return MongoDBAtlasVectorStore.builder(mongoTemplate, embeddingModel) .collectionName("custom_vector_store") // Optional: defaults to "vector_store" .vectorIndexName("custom_vector_index") // Optional: defaults to "vector_index" .pathName("custom_embedding") // Optional: defaults to "embedding" .numCandidates(500) // Optional: defaults to 200 .metadataFieldsToFilter(List.of("author", "year")) // Optional: defaults to empty list .initializeSchema(true) // Optional: defaults to false .batchingStrategy(new TokenCountBatchingStrategy()) // Optional: defaults to TokenCountBatchingStrategy .build(); } // This can be any EmbeddingModel implementation @Bean public EmbeddingModel embeddingModel() { return new OpenAiEmbeddingModel(new OpenAiApi(System.getenv("OPENAI_API_KEY"))); } ---- == Metadata Filtering You can leverage the generic, portable xref:api/vectordbs.adoc#metadata-filters[metadata filters] with MongoDB Atlas as well. For example, you can use either the text expression language: [source,java] ---- vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(5) .similarityThreshold(0.7) .filterExpression("author in ['john', 'jill'] && article_type == 'blog'").build()); ---- or programmatically using the `Filter.Expression` DSL: [source,java] ---- FilterExpressionBuilder b = new FilterExpressionBuilder(); vectorStore.similaritySearch(SearchRequest.builder() .query("The World") .topK(5) .similarityThreshold(0.7) .filterExpression(b.and( b.in("author", "john", "jill"), b.eq("article_type", "blog")).build()).build()); ---- NOTE: Those (portable) filter expressions get automatically converted into the proprietary MongoDB Atlas filter expressions. For example, this portable filter expression: [source,sql] ---- author in ['john', 'jill'] && article_type == 'blog' ---- is converted into the proprietary MongoDB Atlas filter format: [source,json] ---- { "$and": [ { "$or": [ { "metadata.author": "john" }, { "metadata.author": "jill" } ] }, { "metadata.article_type": "blog" } ] } ---- == Tutorials and Code Examples To get started with Spring AI and MongoDB: * See the https://www.mongodb.com/docs/atlas/atlas-vector-search/ai-integrations/spring-ai/#std-label-spring-ai[Getting Started guide for Spring AI Integration]. * For a comprehensive code example demonstrating Retrieval Augmented Generation (RAG) with Spring AI and MongoDB, refer to this https://www.mongodb.com/developer/languages/java/retrieval-augmented-generation-spring-ai/[detailed tutorial]. == Accessing the Native Client The MongoDB Atlas Vector Store implementation provides access to the underlying native MongoDB client (`MongoClient`) through the `getNativeClient()` method: [source,java] ---- MongoDBAtlasVectorStore vectorStore = context.getBean(MongoDBAtlasVectorStore.class); Optional nativeClient = vectorStore.getNativeClient(); if (nativeClient.isPresent()) { MongoClient client = nativeClient.get(); // Use the native client for MongoDB-specific operations } ---- The native client gives you access to MongoDB-specific features and operations that might not be exposed through the `VectorStore` interface. ================================================ FILE: spring-ai-docs/src/main/antora/modules/ROOT/pages/api/vectordbs/neo4j.adoc ================================================ = Neo4j This section walks you through setting up `Neo4jVectorStore` to store document embeddings and perform similarity searches. link:https://neo4j.com[Neo4j] is an open-source NoSQL graph database. It is a fully transactional database (ACID) that stores data structured as graphs consisting of nodes, connected by relationships. Inspired by the structure of the real world, it allows for high query performance on complex data while remaining intuitive and simple for the developer. The link:https://neo4j.com/docs/cypher-manual/current/indexes-for-vector-search/[Neo4j's Vector Search] allows users to query vector embeddings from large datasets. An embedding is a numerical representation of a data object, such as text, image, audio, or document. Embeddings can be stored on _Node_ properties and can be queried with the `db.index.vector.queryNodes()` function. Those indexes are powered by Lucene using a Hierarchical Navigable Small World Graph (HNSW) to perform a k approximate nearest neighbors (k-ANN) query over the vector fields. == Prerequisites * A running Neo4j (5.15+) instance. The following options are available: ** link:https://hub.docker.com/_/neo4j[Docker] image ** link:https://neo4j.com/download/[Neo4j Desktop] ** link:https://neo4j.com/cloud/aura-free/[Neo4j Aura] ** link:https://neo4j.com/deployment-center/[Neo4j Server] instance * If required, an API key for the xref:api/embeddings.adoc#available-implementations[EmbeddingModel] to generate the embeddings stored by the `Neo4jVectorStore`. == Auto-configuration [NOTE] ==== There has been a significant change in the Spring AI auto-configuration, starter modules' artifact names. Please refer to the https://docs.spring.io/spring-ai/reference/upgrade-notes.html[upgrade notes] for more information. ==== Spring AI provides Spring Boot auto-configuration for the Neo4j Vector Store.

Please have a look at the list of xref:#neo4jvector-properties[Configuration Properties] for the vector store to learn about the default values and configuration options. TIP: Refer to the xref:getting-started.adoc#artifact-repositories[Artifact Repositories] section to add Maven Central and/or Snapshot Repositories to your build file. The 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. NOTE: this is a breaking change! In earlier versions of Spring AI, this schema initialization happened by default. Additionally, you will need a configured `EmbeddingModel` bean.
