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 -->  <listener>  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <!-- 配置分发请求的前端控制器 -->  <servlet>  <servlet-name>dispatcher</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <init-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath:springmvc.xml</param-value>  </init-param>  </servlet>  <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>  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  <init-param>  <param-name>forceEncoding</param-name>  <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>  <filter-name>encode</filter-name>  <url-pattern>/*</url-pattern>  </filter-mapping></web-app>

2.springmvc.xml文件配置：

<?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:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"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-4.0.xsd">        <!-- 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/" /><property name="suffix" value=".jsp" />    </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="/js/" mapping="/js/*" />  <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"  xmlns:aop="http://www.springframework.org/schema/aop"  xmlns:tx="http://www.springframework.org/schema/tx"  xsi:schemaLocation="http://www.springframework.org/schema/beans                        http://www.springframework.org/schema/beans/spring-beans.xsd                        http://www.springframework.org/schema/context                       http://www.springframework.org/schema/context/spring-context-3.1.xsd                       http://www.springframework.org/schema/tx                        http://www.springframework.org/schema/tx/spring-tx.xsd                        http://www.springframework.org/schema/aop                        http://www.springframework.org/schema/aop/spring-aop.xsd ">       <!-- 自动扫描包 -->   <context:component-scan base-package="com.cn.su"></context:component-scan>             <!-- 引入配置文件 -->            <bean id="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="location" value="classpath:jdbc.properties" /></bean>     <!-- dataSource数据源配置 --><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close"><property name="driverClassName" value="${driver}" /><property name="url" value="${url}" /><property name="username" value="${username}" /><property name="password" value="${password}" /><!-- 初始化连接大小 --><property name="initialSize" value="${initialSize}"></property><!-- 连接池最大数量 --><property name="maxActive" value="${maxActive}"></property><!-- 连接池最大空闲 --><property name="maxIdle" value="${maxIdle}"></property><!-- 连接池最小空闲 --><property name="minIdle" value="${minIdle}"></property><!-- 获取连接最大等待时间 --><property name="maxWait" value="${maxWait}"></property></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"><!-- spring会自动查找该包下的类 --><property name="basePackage" value="com.cn.su.dao" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property></bean><!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!-- 配置事物的传播性 --><tx:advice id="txAdvice" transaction-manager="transactionManager">          <tx:attributes>              <!-- 传播行为 -->              <!-- REQUIRED:支持当前事务，如果当前没有事务，就新建一个事务；                   SUPPORTS：支持当前事务，如果当前没有事务，就以非事务的方式执行               -->              <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 {@Autowiredprivate 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;@Servicepublic class UserServiceImpl implements IUserService{@Autowiredprivate IUserDao iUserDao;@Overridepublic 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：
