Handle error 404 in web application - not REST application

Question

I\'m trying to handle 404 error using an @ControllerAdvice in a Spring MVC application totally configured using Javaconfig.

Spring MVC version is 4.1.5<

Answer 1

The solution is to extend AbstractAnnotationConfigDispatcherServletInitializer and override this method:

@Override
protected DispatcherServlet createDispatcherServlet(WebApplicationContext servletAppContext) {
    final DispatcherServlet dispatcherServlet = (DispatcherServlet) super.createDispatcherServlet(servletAppContext);
    dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
    return dispatcherServlet;
}

OR this one:

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

And finally in your ControlerAdvice use this:

@ExceptionHandler(NoHandlerFoundException.class)
public String error404(Exception ex) {

    return new ModelAndView("404");
}
