整合Mybatis方式二

通过继承SqlSessionDaoSupport

UserMapperImpl：
可通过getSqlSession()直接获得一个template

package com.annan.mapper;

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

import java.util.List;

public class UserMapperImpl2 extends SqlSessionDaoSupport implements UserMapper {
    @Override
    public List<User> selectUser() {


        return getSqlSession().getMapper(UserMapper.class).selectUser();
    }
}

applicationContext.xml
对应userMapper2
