    //獲取分頁數據

    System.out.println("總頁數："+page.getPages());
    System.out.println("是否有上一頁："+page.hasPrevious());
    System.out.println("是否有下一頁："+page.hasNext());
}

//傳入參數攜帶Ipage接口
//返回結果為IPage
IPage<User> selectPageVo(IPage<?> page, Integer id);

接口實現

<select id="selectPageVo" resultType="xxx.xxx.xxx.User">
    SELECT * FROM user WHERE id > #{id}
</select>

測試

@Test
public void testQuick(){

    IPage page = new Page(1,2);

    userMapper.selectPageVo(page,2);

    long current = page.getCurrent();
    System.out.println("current = " + current);
    long pages = page.getPages();
    System.out.println("pages = " + pages);
    long total = page.getTotal();
    System.out.println("total = " + total);
    List records = page.getRecords();
    System.out.println("records = " + records);
