MyBatisPlus分页查询

MyBatis Plus自带分页插件，只要简单的配置即可实现分页功能

 

 

配置类中添加@Bean配置

 

/**
 * 分页插件
 */
@Bean
public PaginationInterceptor paginationInterceptor() {
    return new PaginationInterceptor();
}

 

 

@Test
public void testSelectPage() {
    Page<User> page = new Page(1,3);
    Page<User> userPage = userMapper.selectPage(page, null);
    //返回对象得到分页所有数据
    long pages = userPage.getPages(); //总页数
    long current = userPage.getCurrent(); //当前页
    List<User> records = userPage.getRecords(); //查询数据集合
    long total = userPage.getTotal(); //总记录数
    boolean hasNext = userPage.hasNext();  //下一页
    boolean hasPrevious = userPage.hasPrevious(); //上一页

    System.out.println(pages);
    System.out.println(current);
    System.out.println(records);
    System.out.println(total);
    System.out.println(hasNext);
    System.out.println(hasPrevious);
}
