弹簧控制器无法识别

我试过下面的代码，用tomcat7运行样本spring rest应用程序。它工作正常，但它无法识别HelloController。调试程序无法访问Hellocontroller。 http://localhost:8080/Sample/welcome引发404错误。弹簧控制器无法识别

127.0.0.1 - - - 25/09/2015:23:21:27 +0530 "GET/HTTP/1.1" 404 - 
127.0.0.1 - - - 25/09/2015:23:21:28 +0530 "GET /Sample/ HTTP/1.1" 200 - 
127.0.0.1 - - - 25/09/2015:23:21:34 +0530 "GET /Sample/welcome HTTP/1.1" 404 -

HelloController.java

package com.mkyong.web.controller; 


    @Controller 
public class HelloController { 

    @RequestMapping(value = { "/", "/welcome**" }, method = RequestMethod.GET) 
    public ModelAndView welcomePage() { 

     ModelAndView model = new ModelAndView(); 
     model.addObject("title", "Spring Security Hello World"); 
     model.addObject("message", "This is welcome page!"); 
     model.setViewName("hello"); 
     return model; 

    } 

    @RequestMapping(value = "/admin**", method = RequestMethod.GET) 
    public ModelAndView adminPage() { 

     ModelAndView model = new ModelAndView(); 
     model.addObject("title", "Spring Security Hello World"); 
     model.addObject("message", "This is protected page!"); 
     model.setViewName("admin"); 

     return model; 

    } 

}

您好像缺少spring-servlet-config文件和内容位于spring-security文件中。在WEB-INF文件夹中创建一个文件mvc-dispatcher-servlet.xml，并添加以下代码行：

<beans:beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" 
xmlns:context="http://www.springframework.org/schema/context" 
xsi:schemaLocation="http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
     http://www.springframework.org/schema/context 
     http://www.springframework.org/schema/context/spring-context-3.1.xsd 
     http://www.springframework.org/schema/mvc 
     http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd"> 

    <context:annotation-config /> 
    <context:spring-configured /> 
    <mvc:annotation-driven /> 

    <mvc:default-servlet-handler/> 
</beans:beans>

你会删除从安全配置文件被移动的内容。
