"content": "[Build status:](https://wso2.org/jenkins/job/products/job/msf4j/) \n\n# WSO2 Microservices Framework for Java (MSF4J)\n\nWSO2 Microservices Framework for Java (MSF4J) is a lightweight high performance framework for developing\n& running microservices.\n\nWSO2 MSF4J is one of the highest performing lightweight Java microservices frameworks. The following graphs show the \nthroughput, memory consumption & latency characteristics of MSF4J against other microservices frameworks.\n \n \n\nAn echo service which accepts a 1KB request & echoes it back directly and using a temp file was developed for the respective \nframeworks, and requests were sent for different concurrency values. The test was repeated for each concurrency value for each \nframework and the average throughput was calculated. \nTests were run out of the box without any tuning on 32 core 64GB server in JVM v1.8.0_60 with default configuration.\n\n\n\nMemory usage for each framework was observed after running the 1KB payload echo microservice on each framework & \nsending a number of requests at different concurrency levels to each service. \nThe graph above shows the averaged out values after several runs for each framework.\n \nLatency results was observed using the Apache bench provided percentile values. Results were plotted for \nvarious concurrency levels the simple echo test. \n \n\n\nTests were run out of the box without any tuning on 32 core 64GB server in JVM v1.8.0_60 with default configuration.\n\nMore details about the performance test can found [here](perf-benchmark).\n\n## Hello world with MSF4J\n\nIt is really easy to define & deploy a Java microservice using WSO2 MSF4J. \nYou simply need to annotate your service and deploy it using a single line of code. \n\nLet's get started by writing a hello world MSF4J microservice. \n\nYou can use the [msf4j-microservice](archetypes) Maven [archetype](http://maven.apache.org/archetype/maven-archetype-plugin/generate-mojo.html)\n to create your first MSF4J project. \n Make sure you have JDK 1.8 and Maven 3.x installed, & run the following command.\n\n```\nmvn archetype:generate -DarchetypeGroupId=org.wso2.msf4j \\\n-DarchetypeArtifactId=msf4j-microservice -DarchetypeVersion=2.6.2 \\\n-DgroupId=org.example -DartifactId=Hello-Service -Dversion=0.1-SNAPSHOT \\\n-Dpackage=org.example.service -DserviceClass=HelloService\n```\n\nThis will generate a project structure for you to quickly get started.\nNext navigate to the Hello-Service directory. You will find a pom.xml file and also an src directory.\n\n#### pom.xml\nThis pom file inherits from the msf4j-service/pom.xml. It provides a way of setting things up quickly with minimum \namount of \nconfiguration. Click [here](poms/msf4j-service) for more information.\n\n```xml\n\n\n \n org.wso2.msf4j\n msf4j-service\n 2.6.2\n \n 4.0.0\n\n org.example\n Hello-Service\n 0.1-SNAPSHOT\n WSO2 MSF4J Microservice\n\n \n org.example.service.Application\n \n\n\n```\n\nYou don't need to change anything in this pom.xml file.\n\n#### HelloService.java\nChange the org.example.service.HelloService class as follows to echo back the name input parameter. \nYou can remove the auto generated code and replace it with the following code segment:\n\n```java\npackage org.example.service; \n\nimport javax.ws.rs.GET;\nimport javax.ws.rs.Path;\nimport javax.ws.rs.PathParam;\n\n@Path(\"/hello\")\npublic class HelloService {\n\n @GET\n @Path(\"/{name}\")\n public String hello(@PathParam(\"name\") String name) {\n return \"Hello \" + name;\n }\n\n}\n```\n\n#### Application.java\nThis is the one-liner to deploy your service using WSO2 MSF4J.\n```java\npublic class Application {\n public static void main(String[] args) {\n new MicroservicesRunner()\n .deploy(new HelloService())\n .start();\n }\n}\n```\n\nYou can also pass in the port(s) as an argument to the MicroservicesRunner class constructor. When passing the port(s) \nas an argument, by default it binds to 0.0.0.0 host. Use \"msf4j.host\" environment variable to override the host value. \n\n\n### Build the Service\nRun the following Maven command. This will create the fat jar **Hello-Service-0.1-SNAPSHOT.jar** in the **target** directory.\n```\nmvn package\n```\nThis fat jar is a jar file that contains your microservice as well as all its dependencies.\n\n### Run the Service\nYou just have to run the following command to get your service up and running.\n```\njava -jar target/Hello-Service-*.jar\n```\n\n\n### Test the Service with cURL\nRun the following command or simply go to [http://localhost:8080/hello/wso2]\n(http://localhost:8080/hello/wso2) from your browser.\n```\ncurl http://localhost:8080/hello/wso2\n```\n\nYou should see a response that prints \"Hello wso2\"\n\n## Supported Annotations\n\nIn this section, we will look at the annotations used in MSF4J microservices. As you may have already noticed,\n we support a subset of the JAXRS annotations.\n\n### Class level annotations\n##### @Path\nRoot path for resource methods. All the paths specified in the resource methods will be sub paths of this.\n\n##### @Consumes\nDefault consume media type(s) for resource methods. The resource methods that do not specify @Consume annotation will\n inherit this consume media type(s).\n\n##### @Produces\nDefault produce media type(s) for resource methods. The resource methods that do not specify @Produce annotation will\ninherit this produce media type(s).\n\n\n### Method level annotations\n##### @Path\nEndpoint of the resource method relative to @Path of the container resource class.\n\n##### @Consumes\nMedia type(s) that the method can consume. This overrides the class level @Consumes media types.\n\n##### @Produces\nMedia type(s) that is produced by the method. This overrides the class level @Produces media types.\n\n##### @GET\nHTTP GET method. Specify that the resource method supports HTTP GET method.\n\n##### @PUT\nHTTP PUT method. Specify that the resource method supports HTTP PUT method.\n\n##### @POST\nHTTP POST method. Specify that the resource method supports HTTP POST method.\n\n##### @DELETE\nHTTP DELETE method. Specify that the resource method supports HTTP DELETE method.\n\n##### @HEAD\nHTTP HEAD method. Specify that the resource method supports HTTP HEAD method.\n\n##### @OPTIONS\nHTTP OPTIONS method. Specify that the resource method supports HTTP OPTIONS method.\n\n### Parameter level annotations\n##### @DefaultValue\nSpecify a default value for a resource method parameter. The value will be automatically converted to the \ncorresponding parameter's type.\n\n##### @Context\nInject additional objects to a resource method. Currently supports injection of the following objects.\n\n* org.wso2.msf4j.Request - \n This object can be used to access properties of the HTTP request. The transport session (org.wso2.msf4j.Session) \n can also be accessed via org.wso2.msf4j.Request#getSession(). \n See the [Session-aware service](samples/http-session) sample.\n* org.wso2.msf4j.Response - \n This object can be used to send HTTP responses. You can make responses more clean way by returning an instance of \n javax.ws.rs.core.Response or a POJO. See the [StockQuote-Service]\n (samples/stockquote/fatjar) sample.\n* org.wso2.msf4j.HttpStreamer - \n This object can be used to stream a chunked request body and process it while the request is streaming. \n See the [FileServer](samples/fileserver) sample.\n* org.wso2.msf4j.formparam.FormParamIterator - \n This object can be used to stream a HTML form submission request body and process it while the request is streaming. \n See the [FormParam](samples/formparam) sample.\n\n##### @PathParam\n/StockQuote/{symbol} to get value of symbol. The value will be automatically converted to the corresponding parameter\n type and assigned to that parameter.\n\n##### @QueryParam\n/Students?age=18 to get value of age. The value will be automatically converted to the corresponding parameter type \nand assigned to that parameter.\n\n##### @HeaderParam\nTo read HTTP request header values. The value will be automatically converted to the corresponding parameter type and\n assigned to that parameter.\n \n##### @CookieParam\nExtracts the value from the specified cookie, converts to the corresponding parameter type and assigns the value to \nthat parameter. \n\n##### @FormParam\nTo support HTML form submission with application/x-www-form-urlencoded and multipart/form-data The value will be \nautomatically converted to the corresponding parameter type and assigned to that parameter\n\n##### @FormDataParam\nTo support complex form submission with multipart/form-data content type. E.g file uploads and beans. The values will be \nautomatically converted to the corresponding parameter type and assigned to that parameter\n\n### Lifecycle Callback Methods\nSupport following Java lifecycle callback method annotations. \n\n##### @PostConstruct\nInvoke by the container on newly constructed service instances after all dependency injection has completed and before transport starts. \n\n##### @PreDestroy\nInvoke by the container during server shutdown before the container removes the service instance.\n\nFor a detailed example, check out the lifecycle sample [here](https://github.com/wso2/msf4j/tree/master/samples/lifecycle).\n \n## MSF4J Interceptors\n\nPlease do refer the following for complete instructions.\n\n* [General instructions](/samples/interceptor/README.md)\n* [MSF4J Interceptors - Stand alone mode instructions](/samples/interceptor/fatjar-interceptor-service/README.md)\n* [MSF4J Interceptors - Deployable Jar mode instructions ](/samples/interceptor/deployable-jar-interceptor-service/README.md)\n* [MSF4J Interceptors - OSGi mode instructions](/samples/interceptor/osgi-interceptor-service/README.md)\n* [MSF4J Interceptors with MSF4J Spring - Fat Jar mode](/samples/interceptor/spring-fatjar-interceptor-service/README.md)\n\n## Develop and configure MSF4J services using Spring framework\n\nSpring is a popular Java application development framework which supports concepts like Dependency Injection(DI) \nand Convention over Configuration. Spring support for MSF4J provides following features. \n\n1. Develop MSF4J services as Spring beans \n2. Develop and configure MSF4J components such as Interceptors and ExceptionMappers using Spring. \n3. Use Annotation or XML based Spring configuration to configure internals of MSF4J framework such as ports, SSL etc. \n\nFollowing example illustrates how to use Spring annotations together with MSF4J annotations to build a RESTful service. The main advantage here is service developers can consume Spring features such as dependency injection , Spring AOP etc. in the Spring way. \n\n```java\nimport org.springframework.beans.factory.annotation.Autowired;\nimport org.springframework.stereotype.Component;\n\nimport javax.ws.rs.GET;\nimport javax.ws.rs.Path;\n\n@Component\n@Path(\"/greeting\")\npublic class Hello {\n\n @Autowired\n private HelloService helloService;\n\n @GET\n public String message() {\n return helloService.hello(\" World\");\n }\n}\n```\n\nFor further details refer Spring [Helloworld sample](samples/spring-helloworld).\n\n\n\n## Annotations for Analytics\n\nIn this section, we will look at the annotations available for analytics purposes MSF4J microservices. There are annotations \nfor Metrics and HTTP Monitoring.\n\nYou will need to configure [analytics](analytics) when you want to publish Metrics and HTTP Monitoring events to \nWSO2 Data Analytics Server (DAS).\n\nThe Metrics data will be published to WSO2 DAS periodically. However the HTTP Monitoring events are published on each request.\n\nFor a detailed example, check out the [Metrics and HTTP Monitoring sample](samples/http-monitoring). \n\n### Metrics Annotations\n\nYou can use the Metrics annnotations in your MSF4J microservices to understand how your microservices work in production.\n\nThere are three metrics annotations supported. Those are @Counted, @Metered and @Timed.\n\nEach metric must have a unique name and the MSF4J will use the fully qualified method name as the metric name by default. \nYou can give a custom name by using the \"name\" parameter. This custom name will be appended to the fully qualified method name \nwith a dot character. You can set the \"absolute\" parameter to \"true\" if you want use only the given name as the metric name. \n\nFor example, see following table to understand how the final metric name is built by the Metrics runtime. Let's asssume that the \nannotation is added to the \"hello\" method of \"HelloService\" shown above.\n\n| Metrics Annotation | Metric Name |\n| ------------------------------------------------ | --------------------------------------------------- |\n| @Counted | org.example.service.HelloService.hello |\n| @Counted(name = \"helloCounter\") | org.example.service.HelloService.hello.helloCounter |\n| @Counted(name = \"helloCounter\", absolute = true) | helloCounter |\n\nThe Metrics annotations can be used at the Method level and Class level.\n\nYou can also configure a level in Metrics Annotations. For more information about Metric Levels, \nsee [WSO2 Carbon Metrics](https://github.com/wso2/carbon-metrics). In MSF4J, you can load the metrics level configuration \nvia the System Property named `metrics.level.conf`.\n\n##### @Counted\nCount the method invocations. There is a parameter named \"monotonic\" and it is set to false by default. This means that the\ncounter is decremented when the method returns. This is useful to count the current invocations of the annotated method.\n\nUse `@Counted(monotonic = true)` when you want the counter to increase monotonically. This is useful to count the total invocations \nof the annotated method\n\n##### @Metered\nMeasure the rate of method invocations. This also keeps a count of the total invocations of the annotated method.\n\n##### @Timed\nMaintain a histogram of durations of each method invocation. This also measures the rate of method invocations and keeps a count of the \ntotal invocations of the annotated method. \n\n### HTTP Monitoring Annotation\n\nYou can use the annotation provided for HTTP Monitoring when you want to monitor each HTTP request and see the summary \nin \"HTTP Monitoring Dashboard\".\n\n##### @HTTPMonitored\nMonitor each HTTP request. This annotation can be used at the Class level and the Method level.\n\n### HTTP Message Tracing\nMSF4J supports visual message tracing through user friendly dashboards in WSO2 DAS or Zipkin. MSF4J message tracing provides \na detailed insight to the complex microservices interactions in a system making monitoring, trouble shooting and optimization of \nmicroservices very easy. Please check [WSO2 DAS Tracing](samples/message-tracing/das) and [Zipkin Tracing](samples/message-tracing/zipkin) samples for more details.\n\n### Swagger Annotations\n[Swagger](http://swagger.io/getting-started/) is a standard, language-agnostic interface to REST APIs which allows both \nhumans and computers to discover and understand the capabilities of the service without access to source code, documentation, \nor through network traffic inspection. \n\nMSF4J supports all [Swagger annotations](https://github.com/swagger-api/swagger-core/wiki/Annotations-1.5.X) out of the box.\n\nTo enable swagger support you need to add the following dependency to your project\n```xml\n\n org.wso2.msf4j\n msf4j-swagger\n 2.6.2\n\n```\nIn order to retrieve Swagger definitions of your microservice, go to http://<host>:<port>/swagger?path=<service_base_path>.\n\ne.g. [http://localhost:8080/swagger?path=/hello](http://localhost:8080/swagger?path=/hello)\n\nTo retrieve Swagger definitions of all microservices in your runtime, go to http://<host>:<port>/swagger.\n\ne.g. [http://localhost:8080/swagger](http://localhost:8080/swagger)\n\nNOTE: Even without any Swagger annotation, default Swagger definitions will be generated using the JAXRS annotation\nin your MSF4J microservice.\n\nThe [StockQuote sample](samples/stockquote/fatjar) demonstrates Swagger annotations in action.\n\n### ExceptionMapper \nMSF4J supports [JAXRS ExceptionMapper](https://docs.oracle.com/javaee/7/api/javax/ws/rs/ext/ExceptionMapper.html) \nwhich allows creation of custom responses when exceptions are thrown from MSF4J services. \n\nThe [StockQuote sample](samples/stockquote/fatjar) demonstrates ExceptionMapper in action.\n\nThe following code segment shows how ExceptionMappers are registered with the MSF4J runtime.\n\n```java\nnew MicroservicesRunner().addExceptionMapper(new SymbolNotFoundMapper(), new DuplicateSymbolMapper());\n```\n\n### Circuit Breaker\nNygard's circuit breaker pattern is supported in MSF4J using the Netflix Hystrix library. For more details see the\n[circuit breaker sample](samples/circuitbreaker)\n\n### Complete Feature List\n* Annotation based definition of microservices\n* High performance Netty based transport\n* WSO2 Developer Studio based tooling for microservices development starting from a Swagger API definition\n* Generate Swagger definition using [Swagger annotations](https://github.com/swagger-api/swagger-core/wiki/Annotations-1.5.X)\n* Ability to develop and Configure MSF4J services using Spring framework\n* HTTP request & response streaming including support for javax.ws.rs.core.StreamingOutput.\n* [ExceptionMapper]((https://docs.oracle.com/javaee/7/api/javax/ws/rs/ext/ExceptionMapper.html))\n* Support for metrics & visualization of metrics using WSO2 Data Analytics Server (DAS) dashboards\n* Message tracing with WSO2 DAS or Zipkin to get a detailed visual insight to the microservices interactions\n* Supports circuit breaker using Netflix Hystrix. \n* Support for securing microservices\n* Integration with rendering engines such as Mustache\n* Comprehensive samples demonstrating how to develop microservices based solutions\n"
