Handle error 404 with Spring controller

by

I use spring 4.0 and java configuration. My working code is:

@ControllerAdvice
public class MyExceptionController {
    @ExceptionHandler(NoHandlerFoundException.class)
    public ModelAndView handleError404(HttpServletRequest request, Exception e)   {
            ModelAndView mav = new ModelAndView("/404");
            mav.addObject("exception", e);  
            //mav.addObject("errorcode", "404");
            return mav;
    }
}

In JSP:

    <div class="http-error-container">
        <h1>HTTP Status 404 - Page Not Found</h1>
        <p class="message-text">The page you requested is not available. You might try returning to the <a href="https://stackoverflow.com/questions/13356549/<c:url value="https://stackoverflow.com/"/>">home page</a>.</p>
    </div>

For Init param config:

public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    public void customizeRegistration(ServletRegistration.Dynamic registration) {
        registration.setInitParameter("throwExceptionIfNoHandlerFound", "true");
    }
}

Or via xml:

<servlet>
    <servlet-name>rest-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>throwExceptionIfNoHandlerFound</param-name>
        <param-value>true</param-value>
    </init-param>
</servlet>
