spring、springmvc、mybatis整合配置（注解）

最近整合ssm框架费了不少功夫，所以，把详细配置过程列出来，不足的地方望大侠们指正！

项目目录：

1.web.xml文件配置：

<?xml version="1.0" encoding="UTF-8"?>

  <servlet-mapping>
  	<servlet-name>dispatcher</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>
  
  <!-- 配置编码过滤器 -->
  <filter>
  	<filter-name>encode</filter-name>

    <aop:config>
	    <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.cn.su.service.impl.*.*(..))"/> 
    </aop:config>
</beans>

4.测试：

<1>login.jsp(登录页面)

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登录</title>
</head>
<body>
	<h2>Login</h2>
	<form action="user/checkLogin" method="post">
		username:<input type="text" name="username" value="" placeholder="please enter your username!"/><br>
		password:<input type="password" name="password" value="" placeholder="please enter your password!" /><br>
		<input type="submit" value="登录" />
	</form>
	
	<div>
		<span style="color:red">${errorMessage}</span>
	</div>
</body>
</html>

<2>UserController控制层（userController注入的是IUserService接口，这里不能是实体类UserServiceImpl哦，

这是spring的代理模式决定的，具体看，http://blog.csdn.net/jyp360/article/details/70215002）：

package com.cn.su.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.cn.su.entity.User;
import com.cn.su.service.IUserService;

@Controller
@RequestMapping("/user")
public class UserController {
	@Autowired
	private IUserService iUserService;
	@RequestMapping("/checkLogin")
	public String login(User user,Model model){
		System.out.println("username:"+user.getUsername()+",password:"+user.getPassword());
		boolean flag = iUserService.selectSingleUser(user.getUsername(), user.getPassword());
		if(flag){
			return "success";
		}else{
			model.addAttribute("errorMessage", "用户名或者密码不正确");
			return "login";
		}
	}
}

<3>IUserService

package com.cn.su.service;

public interface IUserService {
	public boolean selectSingleUser(String username,String password);
}

<4>UserServiceImpl

package com.cn.su.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.cn.su.dao.IUserDao;
import com.cn.su.service.IUserService;
@Service
public class UserServiceImpl implements IUserService{
	@Autowired
	private IUserDao iUserDao;

	@Override
	public boolean selectSingleUser(String username,String password) {
		return iUserDao.selectSingleUser(username,password) == 1 ? true : false;
	}
	

}

<5>IUserDao

package com.cn.su.dao;

import org.apache.ibatis.annotations.Param;

public interface IUserDao {
	public int selectSingleUser(@Param("username") String username,@Param("password") String password);
}

<6>UserMapper.xml（值得注意的是，这里的namespace="com.cn.su.dao.IUserDao"注意哦，是以dao接口文件

包取值的，如果不这样写，会报错，详情见：http://blog.csdn.net/u010504064/article/details/47337307）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.cn.su.dao.IUserDao">
	<select id="selectSingleUser" resultType="int" parameterType="com.cn.su.entity.User">
		select EXISTS(select * from tb_user where username = #{username} and password = #{password});
	</select>
</mapper>

最后跳转成功后页面：success.jsp配置在WEB-INF/pages/succes.jsp，路径不要写错了。整合jar包我分享下，

这里有些jar包不需要用到，用到的都在里面。附加上链接地址：
