Send redirect url with @ResponseStatus(value = HttpStatus.MOVED_PERMANENTLY)

I am using an exception class for @ResponseStatus , but I am not able to figure out how do I send redirect URL in case of 301 Permanently Moved error ?

Exception class:

@ResponseStatus(value = HttpStatus.MOVED_PERMANENTLY)
public class ResourceMovedPermanentlyException extends RuntimeException{

}

The question is not very clear. I suppose you want to redirect to a page in case of ResourceMovedPermanentlyException being thrown. In that case you could use the ExceptionHandler annotation:

@ExceptionHandler(ResourceMovedPermanentlyException.class)
public String handleException(final Exception e) {
    return "redirect:/the/target/page";
}

Alternative implementation:

@ExceptionHandler(ResourceMovedPermanentlyException.class)
public String handleException(final RuntimeException e,
                  final HttpServletRequest request, // this can be omitted if not needed
                  final HttpServletResponse response) throws IOException
    response.sendRedirect("/the/page/or/url/you/need/to/redirect");
}

You also could store the redirect URL into the exception:

@ExceptionHandler(ResourceMovedPermanentlyException.class)
public String handleException(final ResourceMovedPermanentlyException e,
                  final HttpServletResponse response) throws IOException
    response.sendRedirect(e.getRedirectUrl());
}

See the ExceptionHandler JavaDoc for more details about the options available for the exception handler method.

I don't think you can add the url with the simplified exception handling you are using.

Check out vzamanillo's solution (use it in a class that is annotated with @ControllerAdvice and a method annotated with @ExceptionHandler). For the whole story of Spring MVC exception handling check out this blog post

You can use a Spring's RedirectView

RedirectView rv = new RedirectView(url);
rv.setStatusCode(HttpStatus.MOVED_PERMANENTLY);
rv.setUrl(url);
ModelAndView mv = new ModelAndView(rv);
return mv;
