可以在LambdaQueryWrapper中添加orderByDesc方法,按照时间倒序排列,修改后的代码如下:
public PageData<SysNotificationEntity> page(NotificationQuery query){
Page<SysNotificationEntity> page = Page.of(query.getPageNum(), query.getPageSize(), query.getCount());
LambdaQueryWrapper<SysNotificationEntity> queryWrapper = new LambdaQueryWrapper<>();
queryWrapper.orderByDesc(SysNotificationEntity::getCreateTime);
page = this.baseMapper.selectPage(page, queryWrapper);
return PageData.of(page);
}
