SpringMVC页面无法跳转0

出现问题：SpringMVC页面无法跳转，老是报：
[WARN ] [19:58:55] org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/MVCdemo/user/login] in DispatcherServlet with name 'springMVC'
之前的项目也是这么写的，毫无问题，现在这个test项目也是简单模仿的，连Hibernate数据库都没用，居然出现这个问题，百度、google搜寻也无果，解决不了。。。下面贴几段核心配置和写法，完整程序见附件，导包的话只要导spring最新版本即可。
1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<!-- Character Encoding filter -->  
    <filter>  
        <filter-name>EncodingFilter</filter-name>  
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
        <init-param>  
            <param-name>encoding</param-name>  
            <param-value>UTF-8</param-value>  
        </init-param> 
        <init-param>  
       		<param-name>forceEncoding</param-name>  
        	<param-value>true</param-value>  
    	</init-param> 
    </filter>  
    <filter-mapping>  
        <filter-name>EncodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping> 
	<!-- 加载所有Spring配置文件 -->
	<context-param>
   		<param-name>contextConfigLocation</param-name>
   		<param-value>
   		/WEB-INF/config/spring-common.xml
   		</param-value>
	</context-param>
	<!-- 配置spring监听 -->
	<listener>  
    	<listener-class>  
        org.springframework.web.context.ContextLoaderListener   
    	</listener-class>  
	</listener> 
	<!-- 配置SpringMVC -->  
  	<servlet>  
    	<servlet-name>springMVC</servlet-name>  
   	    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
    	<init-param>  
        	<param-name>contextConfigLocation</param-name>  
        	<param-value>/WEB-INF/config/spring-common.xml</param-value>  
    	</init-param>  
    	<load-on-startup>1</load-on-startup>  
  	</servlet>  
  	<servlet-mapping>  
    	<servlet-name>springMVC</servlet-name>  
    	<url-pattern>/</url-pattern>  
  	</servlet-mapping> 
</web-app>

2、spring-common.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:context="http://www.springframework.org/schema/context"
     xmlns:mvc="http://www.springframework.org/schema/mvc"
     xmlns:aop="http://www.springframework.org/schema/aop"
     xmlns:tx="http://www.springframework.org/schema/tx"
     xsi:schemaLocation="

     http://www.springframework.org/schema/aop/spring-aop.xsd
     http://www.springframework.org/schema/tx
     http://www.springframework.org/schema/tx/spring-tx.xsd">
	<!-- 声明使用注解的风格 -->
	<context:annotation-config/>
	<!-- 开启mvc注解 -->
	<mvc:annotation-driven />
    <!-- 静态资源(js/image)的访问 -->  
 	<mvc:resources location="/js/" mapping="/js/**"/>  
    <!-- 定义视图解析器 -->    
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/"></property>  
        <property name="suffix" value=".jsp"></property>  
    </bean>   
</beans>

3、UserLoginAction
package com.study.action;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.study.service.UserService;

@Controller
@RequestMapping("/user")
public class UserLoginAction{
	
	@Resource(name="userService")
	private UserService userService;
	
	@RequestMapping("/login")
	public String login(String username,String password,HttpServletRequest request){
		boolean b = userService.search(username,password);
		if(b==true){
			request.setAttribute("username",username);
			return "/ppp/success";
		}else{
			return "/ppp/fail"; 
		}
	}
}


4、index.jsp



    <form action="/MVCdemo/user/login" method="post">

    	用户名<input type="text" name="username"><br />

                     密&nbsp;&nbsp;码<input type="password" name="password"><br />

        <input type="submit" value="提交"> 

    </form>

①：
public String login(******){
//TODO sth
return "/ppp/success";
}
SpringMvc直接去找路径为/ppp/success的物理视图，应该写成
return "/ppp/success.jsp";

②：
也可以这样改：
public ModelAndView login(***){
//TODO sth
return new ModelAndView("ppp/success","username" ,username);
}
最后真实物理视图：prefix+"ppp/success"+suffix = /ppp/success.jsp
