mybatis分頁的幾種方式是什麼

sql使用的核心语句

-- 语法：表示从startIndex下标开始，一页显示pageSize个
select * from users limit startIndex,pageSize;
-- 语法：表示显示[0,n]范围的数据
select * from users limit n;

 //分页查询
    List<User> getUserLImit(Map<String,Object> map);

<!--    分页查询-->
    <select id="getUserLImit" parameterType="map" resultType="pojo.User">
        select * from firend_mq.users limit #{startIndex},#{pageSize}    </select>

    //测试分页查询
    @Test
    public  void getUserLImit(){
        SqlSession sqlSession = Mybatisutil.getSqlSession();
        UserDao mapper = sqlSession.getMapper(UserDao.class);

        Map<String, Object> map = new HashMap<>();
        map.put("startIndex",0);
        map.put("pageSize",3);
        List<User> userLImit = mapper.getUserLImit(map);
        for (User user : userLImit) {
            System.out.println(user);
        }
        sqlSession.close();
    }

//RowBounds实现分页查询
    List<User> getUserLRowBounds();

   <!--   RowBounds 分页查询-->
    <select id="getUserLRowBounds"  resultType="pojo.User">
        select * from firend_mq.users    </select>

    //RowBounds分页查询
    @Test
    public  void getUserLRowBounds(){
        SqlSession sqlSession = Mybatisutil.getSqlSession();
        //RowBounds对象  参数（起点，个数）
        RowBounds rowBounds = new RowBounds(2, 3);

        //通过java代码层面实现分页,第一个参数是接口类的方法路径
        List<User> userlist = sqlSession.selectList("dao.UserDao.getUserLRowBounds", null, rowBounds);
        for (User user : userlist) {
            System.out.println(user);
        }
        sqlSession.close();
    }
