在[Spring整合Mybatis方式一][Spring_Mybatis]的基础上通过SQLSessionDaoSupport方式实现另一种方式完成整合。  
**1、UserMapperImpl2.java**

package com.zhang.mapper;
    import com.zhang.pojo.User;
    import org.mybatis.spring.support.SqlSessionDaoSupport;
    import java.util.List;
    
    public class UserMapperImpl2 extends SqlSessionDaoSupport implements UserMapper { 
        public List<User> selectUser() { 
            return getSqlSession().getMapper(UserMapper.class).selectUser();
        }
    }

**2、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" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">
    
        <import resource="spring-dao.xml"></import>
        <bean id="UserMapper" class="com.zhang.mapper.UserMapperImpl2">
            <property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
        </bean>
    </beans>

**3、MyTest.java**

import com.zhang.mapper.UserMapper;
    import com.zhang.pojo.User;
    import org.apache.ibatis.io.Resources;
    import org.apache.ibatis.session.SqlSession;
    import org.apache.ibatis.session.SqlSessionFactory;
    import org.apache.ibatis.session.SqlSessionFactoryBuilder;
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import java.io.IOException;
    import java.io.InputStream;
    
    public class MyTest { 
        @Test
        public void test() throws IOException { 
    
            ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
            UserMapper mapper = context.getBean("UserMapper",UserMapper.class);
            for (User user : mapper.selectUser() ) { 
                System.out.println(user);
            }
        }
    }

**4、测试结果如下**
