在springmvc3中配置tile时出现Servlet异常

Question

嗨，我正试图在春季3.2.8中配置tiles 2框架，但我得到了以下异常

Aug 28, 2014 11:51:30 AM org.apache.catalina.core.StandardWrapperValve invoke

我的tiles.xml在下面

控制器如下，

@RequestMapping("/login")
    public ModelAndView login(
            @RequestParam(value = "username", required = false) String username,
            @RequestParam(value = "username", required = false) String password) {
        ModelAndView modelAndView = null;
        System.out.println(username);
        System.out.println(password);
        String result = EmrService.login(username, password);
        modelAndView = new ModelAndView("menu");
        /*
         * ArrayList<Users> userlist = EmrService.getUsers();
         * modelAndView.addObject("userlist", userlist);
         */
        return modelAndView;
    }

我在堆栈溢出站点也遇到过同样的问题，但我并没有得到。伙计们，请帮帮我。提前谢谢。

您正在使用org.springframework.web.servlet.view.UrlBasedViewResolver，通过使用tiles 传递要解析的视图

因此，当spring从Login方法返回时，它会尝试在tiles.xml文件中查找名称为menu的视图，而该视图目前在tiles definition (tiles.xml)文件中丢失。

因此，请尝试为menu添加tiles definition (tiles.xml)以解决此问题。
