Spring整合Mybatis（二）-创新互联

通过mapper的实现类继承SqlSessionDaoSupport，但是applacationContext文件中要注入的属性就要从sqlSessionTemplate变成sqlSessionFactory

package com.psy.dao;

import com.psy.pojo.User;
import org.apache.ibatis.session.SqlSession;
import org.mybatis.spring.support.SqlSessionDaoSupport;

public class UserDaoImpl2 extends SqlSessionDaoSupport implements UserDao {@Override
    public User queryUserById(Integer id) {SqlSession sqlSession = getSqlSession();
        UserDao mapper = sqlSession.getMapper(UserDao.class);
        return mapper.queryUserById(id);
    }
}

@Test
public void test2() {ClassPathXmlApplicationContext cp = new ClassPathXmlApplicationContext("applicationContext.xml");
    UserDao userDao = cp.getBean("userDao", UserDao.class);
    System.out.println(userDao.queryUserById(1));
}
