Spring 3 - Create ExceptionHandler for NoSuchRequestHandlingMethodException

Question

Using Spring 3, I like to create an exception handler using the ExceptionHandler annotation that will handle \"no page found (404)\" requests.

Answer 1

In Spring 3.2 you can use @ContollerAdvice to have an ExceptionHandler for all your Controllers like this:

@ControllerAdvice
public class GeneralHandler {

   @ExceptionHandler
   public ModelAndView handleException (NoSuchRequestHandlingMethodException ex) {
        ModelAndView mav = new ModelAndView();
        ...
        return mav;
   }
}

You can even add more annotations to return serialized json

@ExceptionHandler
    @ResponseBody
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public RestError resolveBindingException ( MethodArgumentNotValidException methodArgumentNotValidException, Locale locale )
    {
        BindingResult bindingResult = methodArgumentNotValidException.getBindingResult();
        return getRestError(bindingResult, locale);
    }
