Status messages on the Spring MVC-based site (annotation controller)

annotations, controller, java, spring-mvc

Solution

As mentioned by muanis, since spring 3.1, the best approach would be to use RedirectAttributes. I added i18n to the sample given in the blog. So this would be a complete sample.

@RequestMapping("/users")
@Controller
public class UsersController {

            @Autowired
            private MessageSource messageSource;

            @RequestMapping(method = RequestMethod.POST, produces = "text/html")
            public String create(@Valid User user, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest, Locale locale, RedirectAttributes redirectAttributes) {
                ...
                ...
                redirectAttributes.addFlashAttribute("SUCCESS_MESSAGE", messageSource.getMessage("label_user_saved_successfully", new String[] {user.getUserId()}, locale));
                return "redirect:/users/" + encodeUrlPathSegment("" + user.getId(), httpServletRequest);
            }
    ...
    ...
}

Add appropriate message in your message bundle, say messages.properties.

label_user_saved_successfully=Successfully saved user: {0}

Edit your jspx file to use the relevant attribute

<c:if test="${SUCCESS_MESSAGE != null}">
  <div id="status_message">${SUCCESS_MESSAGE}</div>
</c:if>
