Return HTTP 204 on null with spring @RestController

Question

This returns 200 OK with Content-Length: 0

@RestController
public class RepoController {
    @RequestMapping(value = \"/document/{id}\", method = RequestMeth         


        

Answer 1

Question is old but for those that needs a global answer and have Spring 4+, you can create a ResponseBodyAdvice that changes response code base on the controller response. The following exemple do it for all @RestController classes :

@ControllerAdvice(annotations = { RestController.class })
public class NullToNoContentResponseBodyAdvice
    implements ResponseBodyAdvice
