  本文主要介绍了如何将mybatis和spring整合在一起使用,本人使用的是mybatis3.05 + spring3.1.0M2 ,使用dbcp作为数据库连接池。

1.编写数据访问接口(UserDao.java)

bubuko.com,布布扣
package com.mybatis;
publicinterface UserDao {
    publicint countAll();
}

2.编写数据访问接口映射文件(UserDaoMapper.xml)

bubuko.com,布布扣
<?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.编写mybatis配置文件(MyBatis-Configuration.xml)

bubuko.com,布布扣
<?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.编写服务层接口(UserService.java)

bubuko.com,布布扣
package com.mybatis;

publicinterface UserService {
    publicint countAll();
}
bubuko.com,布布扣

 

5.编写服务层实现代码(UserServiceImpl.java)

bubuko.com,布布扣
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.编写spring配置文件(applicationContext.xml)

bubuko.com,布布扣
<?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.测试代码(UserServiceTest.java)

bubuko.com,布布扣
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());
    }
}
