        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);

        MyUserMapperAnnotation mapper = session.getMapper(MyUserMapperAnnotation.class);
        
        // 分页
        PageHelper.startPage(1, 2);

        System.out.println(mapper.selectMyUser());
    } finally {
        if (session != null) {
