查询

public static void main(String[] args) throws IOException {

    try {
        InputStream inputStream = Resources.getResourceAsStream("mybatis-config.xml");
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        session = sqlSessionFactory.openSession();
        MyUserMapperAnnotation mapper = session.getMapper(MyUserMapperAnnotation.class);
        
        // 分页
        PageHelper.startPage(1, 2);

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