   public void test01() throws IOException {
        //读取核心配置文件sqlMapConfig.xml
        InputStream inputStream =
                Resources.getResourceAsStream("mybatis.xml");

        //获取SqlSessionFactory对象
        SqlSessionFactory sessionFactory =
                new SqlSessionFactoryBuilder().build(inputStream);

        //获取sqlSession
        SqlSession session = sessionFactory.openSession();

        //调用"namespace+id"
        List<User> userList = session.selectList("pojo.UserMapper.findAll");
        System.out.println(userList);
    }

mybatis.xml 中引入mapper.xml
