Different response from a controller method based on HTTP Response code

Question

How do you write a controller method which can either return a View or HTTP response status code based on if its 200 then view else the response status code.

 @RequestMapping(value="/",method=RequestMethod.GET)
 public String showLanding()
 {
    return View.Landing;     
 }

I want to handle in case of 401, 403, 500 etc. just status code should be returned instead of view.

To return the 403- Unauthorized status code,

@RequestMapping(value="/",method=RequestMethod.GET)
public String showLanding()
{
     return HttpStatus.UNAUTHORIZED;    
}

You might want to fix your return type. – Sotirios Delimanolis Apr 07 '14 at 20:00

You could also check out the @ResponseStatus annotation as well as ResponseEntity (for more dynamic scenarios)

But at a time I can only do one .. right ? As i said i want to have view or response status code – Novice User Apr 07 '14 at 18:16
I am not sure that's such a good idea. Maybe you should separate the controller methods... – geoand Apr 07 '14 at 18:21

I'm far from suggesting that you should do flow control with Exceptions - but those HTTP statuses are errors and exceptions. So you might want to throw business exceptions from your controller methods and then handle those using @ExceptionHandlers.

You can also target a subset of Controllers and assist those with Exception handling using @ControllerAdvice.
