What to return if Spring MVC controller method doesn’t return value?

by

you can return void, then you have to mark the method with @ResponseStatus(value = HttpStatus.OK) you don’t need @ResponseBody

@RequestMapping(value = "/updateSomeData" method = RequestMethod.POST)
@ResponseStatus(value = HttpStatus.OK)
public void updateDataThatDoesntRequireClientToBeNotified(...) {
    ...
}

Only get methods return a 200 status code implicity, all others you have do one of three things:

  • Return void and mark the method with @ResponseStatus(value = HttpStatus.OK)
  • Return An object and mark it with @ResponseBody
  • Return an HttpEntity instance
