How to return completely empty response in Spring

Question

I have a Spring MVC Rest controller with one of the URL mappings being :

myhost:8080/helloworldexample/testnullresponse

Now, is it possible to return nothing at all when I call this URL

Nothing means: no body, no response, no status code simply nothing at all, almost like the server listening to the request did not do anything.

I would appreciate any help on this. I have tried the following options but nothing worked:

 return new ResponseEntity<Void>(null);

AND

    @RequestMapping(value = "/helloworldexample/testnullresponse", produces = "application/json; charset=UTF-8", method = RequestMethod.GET)
  public void nullResponse(HttpServletRequest request) {
        }

Answer 1

Actually your controller's method could return void. Here is an example

@RequestMapping(value = "/helloworldexample/testnullresponse", method = RequestMethod.HEAD)
public void nullResponse(HttpServletResponse response) {
...
}
