Handle error 404 with Spring controller

Question

I use @ExceptionHandler to handle exceptions thrown by my web app, in my case my app returns JSON response with HTTP status for error

Answer 1

With spring > 3.0 use @ResponseStatus

  @ResponseStatus(value = HttpStatus.NOT_FOUND)
  public class ResourceNotFoundException extends RuntimeException {
    ...
}

    @Controller
    public class MyController {
    @RequestMapping.....
    public void handleCall() {
        if (isFound()) {
        // do some stuff
        }
        else {
              throw new ResourceNotFoundException(); 
        }
    }
}
