# Swagger generated server ## Overview Using the swagger-codegen, you can not only generate clients but servers as well! The same spec can be used to drive your development both ways. This is an example of generating a server for `JAX-RS`. ### Prerequisites You need the following installed and available in your $PATH:
  • Maven 3
  • ### Generating a server You first need to build the `swagger-codegen` project--this is done by running this command at the root of the swagger-codegen project: ``` sbt assembly ``` You can now generate a server from any valid[**](https://github.com/wordnik/swagger-codegen/blob/master/README.md#validating-your-swagger-spec) swagger spec: ``` ./bin/runscala.sh samples/server-generator/java-jaxrs/JavaJaxRSServerGenerator.scala http://petstore.swagger.wordnik.com/api/api-docs.json special-key ``` After executing this script, you will have an output directory with the server-generated files: ``` $ cd samples/server-generator/java-jaxrs/output $ find . ./pom.xml ./README.md ./src ./src/main ./src/main/java ./src/main/java/com ./src/main/java/com/wordnik ./src/main/java/com/wordnik/api ./src/main/java/com/wordnik/api/ApiException.java ./src/main/java/com/wordnik/api/ApiResponse.java ./src/main/java/com/wordnik/api/JacksonJsonProvider.java ./src/main/java/com/wordnik/api/NotFoundException.java ./src/main/java/com/wordnik/api/PetApi.java ./src/main/java/com/wordnik/api/StoreApi.java ./src/main/java/com/wordnik/api/UserApi.java ./src/main/java/com/wordnik/client ./src/main/java/com/wordnik/client/model ./src/main/java/com/wordnik/client/model/Category.java ./src/main/java/com/wordnik/client/model/Order.java ./src/main/java/com/wordnik/client/model/Pet.java ./src/main/java/com/wordnik/client/model/Tag.java ./src/main/java/com/wordnik/client/model/User.java ./src/main/webapp ./src/main/webapp/WEB-INF ./src/main/webapp/WEB-INF/web.xml ``` To run the server, cd to the `samples/server-generator/java-jaxrs/output` folder and run: ``` mvn jetty:run ``` You can now load the swagger-ui against `http://localhost:8002/api/api-docs.json`. Of course this isn't a fully runnable server! You have to add the logic in the **/api/*.java files. But that's the easy part. ### Making it your own Running the sample is easy, but how about making your own server? Easy! Just modify the `samples/server-generator/java-jaxrs/JavaJaxRSServerGenerator.scala` file. Don't like the templates? Don't worry, we're not offended! They're [mustache](http://mustache.github.com/) templates and are easy to modify. Take a look at the sample templates here:
  • - Generator for your api classes: [api.mustache](https://github.com/wordnik/swagger-codegen/blob/master/samples/server-generator/java-jaxrs/templates/api.mustache)
  • - Generator for your models: [model.mustache](https://github.com/wordnik/swagger-codegen/blob/master/samples/server-generator/java-jaxrs/templates/model.mustache)
  • - Your web.xml: [web.mustache](https://github.com/wordnik/swagger-codegen/blob/master/samples/server-generator/java-jaxrs/templates/web.mustache) Sound easy? It is!
