本文主要介紹瞭如何將mybatis和spring整合在一起使用，本人使用的是mybatis3.05 + spring3.1.0M2 ，使用dbcp作為資料庫連線池。

1.編寫資料訪問介面（UserDao.java）

package com.mybatis;
publicinterface UserDao {
publicint countAll();
}

2.編寫資料訪問介面對映檔案（UserDaoMapper.xml）

<?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.mybatis.UserDao"><select id="countAll" resultType="int">
        select count(*) c from user;
</select></mapper>

3.編寫mybatis配置檔案（MyBatis-Configuration.xml）

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd"
 
><configuration><mappers><mapper resource="com/mybatis/UserDaoMapper.xml"/></mappers></configuration>

4.編寫服務層介面（UserService.java）

package com.mybatis;

publicinterface UserService {
publicint countAll();
}

5.編寫服務層實現程式碼（UserServiceImpl.java）

package com.mybatis;

publicclass UserServiceImpl 
 
implements UserService {
private UserDao userDao;

public UserDao getUserDao() {
return userDao;
    }
publicvoid setUserDao(UserDao userDao) {
this.userDao = userDao;
    }

publicint countAll() {
returnthis.userDao.countAll();
    }
}

6.編寫spring配置檔案（applicationContext.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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"><property name="driverClassName" value="com.mysql.jdbc.Driver"></property><property name="url" value="jdbc:mysql://localhost:3306/hlp?useUnicode=true&amp;characterEncoding=UTF-8&amp;zeroDateTimeBehavior=convertToNull"></property><property name="username" value="root"></property><property name="password" value="1234"></property><property name="maxActive" value="100"></property><property name="maxIdle" value="30"></property><property name="maxWait" value="500"></property><property name="defaultAutoCommit" value="true"></property></bean><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="configLocation" value="classpath:MyBatis-Configuration.xml"></property><property name="dataSource" ref="dataSource"/></bean><bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean"><property name="mapperInterface" value="com.mybatis.UserDao"></property><property name="sqlSessionFactory" ref="sqlSessionFactory"></property></bean><bean id="userService" class="com.mybatis.UserServiceImpl"><property name="userDao" ref="userDao"></property></bean></beans>

7.測試程式碼（UserServiceTest.java）

package com.mybatis;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;


publicclass UserServiceTest {

    @Test
publicvoid userServiceTest(){
        ApplicationContext context =new ClassPathXmlApplicationContext("applicationContext.xml");
        UserService userService = (UserService)context.getBean("userService");
        System.out.println(userService.countAll());
    }
}
