[Jersey] Building Responses

Jersey에선 Response를 다음과 같이 할 수 있다.

POST 메소드인 경우의 예를 들면,

Jersey에선 POST는 작업을 수행한 후 정상적으로 처리되면 201 상태코드를 리턴하고 Location Header에는 새롭게 생성된 리소스의 URI값을 리턴할 수 있다.

 이렇게 자바의 내용이 이렇다면, 

    @POST

    @Path("post")

    public Response post(String id) throws URISyntaxException{

     URI createdUri = new URI("http://localhost:8080/user/" + id);

     create(id);

     return Response.created(createdUri).build();

    }

    

    @POST

    @Path("postEntity")

    public Response postEntity(String id) throws URISyntaxException{

     URI createdUri = new URI("http://localhost:8080/user/" + id);

     String created = create(id);

     return Response.created(createdUri).entity(created).build();

    }

    private String create(String content) {

System.out.println("post : " + content);

                //content create..

return content;

}

1. 201 상태코드 리턴하고 Location header에 값 넣어서 리턴하기.

2. Entity body에 custom response를 추가하는 방법.

$ curl -v -d "flyburi" http://localhost:8080/JerseyDemo/form/postEntity

* About to connect() to localhost port 8080 (#0)

*   Trying 127.0.0.1... connected
