Exception Handling in Spring MVC

The following link provides good explanation for exception handling in Spring MVC.

In addition, it also provides the sample to demonstrate it.

I recognized the ResponseStatus annotation is very useful to return abnormal http status.

@ResponseStatus(value = HttpStatus.NOT_FOUND, reason = "No such order")
public class OrderNotFoundException extends RuntimeException {

	/**
	 * Unique ID for Serialized object
	 */
	private static final long serialVersionUID = -8790211652911971729L;

	public OrderNotFoundException(String orderId) {
		super(orderId + " not found");
	}
}

In the case of using ControllerAdvice, the following code should be considered if you let other exceptions with ResponseStatus annotation  be handled as it is.

@ControllerAdvice
public class GlobalExceptionHandlingControllerAdvice {

	@ExceptionHandler(SupportInfoException.class)
	public ModelAndView handleError(HttpServletRequest req, Exception exception)
			throws Exception {

		// Rethrow annotated exceptions or they will be processed here instead.
		if (AnnotationUtils.findAnnotation(exception.getClass(),
				ResponseStatus.class) != null)
			throw exception;

		logger.error("Request: " + req.getRequestURI() + " raised " + exception);

		ModelAndView mav = new ModelAndView();
		mav.addObject("exception", exception);
		mav.addObject("url", req.getRequestURL());
		mav.addObject("timestamp", new Date().toString());
		mav.addObject("status", 500);

		mav.setViewName("support");
		return mav;
	}

}
