mapper接口的实现

// 手动注入sqlSession或继承SqlSessionDaoSupport
public class UserMapperImpl extends SqlSessionDaoSupport implements UserMapper{
    
    /*private SqlSessionTemplate sqlSessionTemplate;
    public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) {
        this.sqlSessionTemplate = sqlSessionTemplate;
    }*/
    @Override
    public List<User> getUserList() {
        // return sqlSessionTemplate.getMapper(UserMapper.class).getUserList();
        return getSqlSession().getMapper(UserMapper.class).getUserList();
    }
}

测试

public static void main(String[] args) {
    ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
    UserMapper userMapper = context.getBean("userMapperImpl", UserMapper.class);
    userMapper.getUserList();
}
