I know I'm late to the party, but I found a much more elegant solution imho.

Instead of adding a filter for the multipart resolver, simply add throws MaxUploadSizeExceededException on your controller method and add the filter for the DelegatingFilterProxy in your web.xml and you can add an exception handler right in your controller without having to redirect the request.

e.g.:

Method (in Controller):

@RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
public ResponseEntity uploadFile(MultipartHttpServletRequest request) throws MaxUploadSizeExceededException {
    //code
}

Exception Handler (in same controller):

@ExceptionHandler(MaxUploadSizeExceededException.class)
public ResponseEntity handleSizeExceededException(HttpServletRequest request, Exception ex) {
    //code
}

Web.xml (thanks to Rob Winch):

    
        Secures access to web resources using the Spring Security framework.
    
    springSecurityFilterChain
    springSecurityFilterChain
    org.springframework.web.filter.DelegatingFilterProxy


    springSecurityFilterChain
    /*
    ERROR
    REQUEST

And that is all you need.
