Performing a redirect from a spring MVC @ExceptionHandler method

Question

I want to have the following method:

@ExceptionHandler(MyRuntimeException.class)
public String myRuntimeException(MyRuntimeException e, RedirectAttributes redire         


        

Answer 1

Note that this is actually supported out-of-the-box by Spring 4.3.5+ (see SPR-14651 for more details).

I've managed to get it working using the RequestContextUtils class. My code looks like this

@ExceptionHandler(MyException.class)
public RedirectView handleMyException(MyException ex,
                             HttpServletRequest request,
                             HttpServletResponse response) throws IOException {
    String redirect = getRedirectUrl(currentHomepageId);

    RedirectView rw = new RedirectView(redirect);
    rw.setStatusCode(HttpStatus.MOVED_PERMANENTLY); // you might not need this
    FlashMap outputFlashMap = RequestContextUtils.getOutputFlashMap(request);
    if (outputFlashMap != null){
        outputFlashMap.put("myAttribute", true);
    }
    return rw;
}

Then in the jsp page I simply access the attribute

Hope it helps!
