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
[code="java"]
<?xml version="1.0" encoding="UTF-8"?>
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2、spring-common.xml
[code="java"]

[/code]
3、UserLoginAction
[code="java"]
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";
}
}
}
[/code]
4、index.jsp
[/code]
用户名
密 码
[/code]
