春天的MVC映射问题

我有我认为是一个简单的Spring MVC应用程序。不过，我似乎可以正确设置requestMappings。奇怪的是，日志显示url映射到正确的控制器，但Dispatcher似乎无法在运行时找到它。任何建议，将不胜感激：春天的MVC映射问题

<!-- The Spring MVC framework handles all of this stuff. Just pass it along -->

控制器类：

@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); 
} 
}

您不能重复在 “/应用程序” @RequestMapping和<url-pattern>。也就是说，你的sayHello现在被映射到“/ app/app/index”。你可以写

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

（或者你可以在你的配置声明DefaultAnnotationHandlerMapping豆及其allwaysUseFullPath属性设置为true覆盖默认行为）
