How to display a HTTP status code of a url (For example, 404, 200, etc. ) on Spring's JSP page?

I need to display a HTTP status code like 404, 200, 500, etc. of a url on a jsp page in Spring MVC. I have tried to read a lot of the online documentations but a lot of them do not show you how to exactly do it and get it displayed on a jsp page.

I have my controller like this:

@Controller
public class HomeController {

    @ResponseStatus(HttpStatus.BAD_REQUEST)

    @ResponseBody ErrorInfo handleBadRequest(HttpServletRequest req, Exception ex) {
        return new ErrorInfo(req.getRequestURL(), ex);
    } 
}

And my jsp:

<p>The error is : ${ex} </p>

And also tell me what kind of Maven dependency I need in my pom.xml file.

Thanks!
