Spring MVC mapping problem

Question

I have what I thought was a simple Spring MVC application. However, I can configure requestMappings correctly. It is strange that in the logs it is shown that the URL is mapped to the correct controller, but the Dispatch cashier seems to find it at run time. Any suggestions would be highly appreciated:

Web.xml File

 <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- The Spring MVC framework handles all of this stuff. Just pass it along --> <servlet> <servlet-name>wisi</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>wisi</servlet-name> <url-pattern>/app/*</url-pattern> </servlet-mapping> 

Controller Class:

 @Controller public class MainController { @Autowired private LearningEntryService learningEntryService; public LearningEntryService getLearningEntryService() { return learningEntryService; } public void setLearningEntryService(LearningEntryService learningEntryService) { this.learningEntryService = learningEntryService; } @RequestMapping(value = "/app/index", method = RequestMethod.GET) public ModelAndView sayHello(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { Map<String, Object> model = new HashMap<String, Object>(); List<LearningEntry> le = learningEntryService.getLearningEntries(); model.put("learningEntries", le); return new ModelAndView("main", model); } } 

Answer 1

You cannot duplicate "/ application" in both @RequestMapping and <url-pattern> . That is, your sayHello now displayed on "/ app / app / index". You can write

 @RequestMapping(value = "/index", method = RequestMethod.GET) 

(Or you can declare DefaultAnnotationHandlerMapping bean in your configuration and set the allwaysUseFullPath property to true to override the default behavior)
