本文整理了Java中org.springframework.data.domain.Sort类的一些代码示例，展示了Sort类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Sort类的具体详情如下：
包路径：org.springframework.data.domain.Sort
类名称：Sort

Sort介绍

[英]Sort option for queries. You have to provide at least a list of properties to sort for that must not include null or empty strings. The direction defaults to Sort#DEFAULT_DIRECTION.
[中]查询的排序选项。您必须至少提供一个属性列表进行排序，这些属性不能包含null或空字符串。方向默认为排序#默认_方向。
