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"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>ssm</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- 配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mybatis.xml</param-value>
</context-param>
<!-- 配置spring监听器 -->

<param-value>True</param-value>
</init-param>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>

<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>

2.springmvc.xml文件配置：

<!-- 配置控制层扫描包路径 -->
<context:component-scan base-package="com.cn.su.controller"></context:component-scan>

<!-- 配置视图层跳转 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/" />

</bean>

<!-- 静态资源配置 -->
<mvc:annotation-driven /><!-- 启动注解，配置静态资源必须 -->
<mvc:resources location="/" mapping="/*.html" />
<mvc:resources location="/css/" mapping="/css/*" />

<mvc:resources location="/images/" mapping="/images/*" />
</beans>

3.spring-mybatis.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 自动扫描包 -->

</bean>

<!-- sessionFactory工厂配置 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- mybatis和spring完美配置，不需要配置mapper映射文件 -->
<property name="mapperLocations" value="classpath*:com/cn/su/mapper/*.xml"></property>
</bean>

<!-- dao层配置 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>

<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->

-->
<tx:method name="save*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="insert*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
<tx:method name="select*" propagation="SUPPORTS" read-only="true"/>
<tx:method name="query*" propagation="SUPPORTS" read-only="true"/>
</tx:attributes>
</tx:advice>

<!-- 配置aop切面 -->
<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：
