本文整理了Java中org.grails.datastore.mapping.query.Query类的一些代码示例，展示了Query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。Query类的具体详情如下：
包路径：org.grails.datastore.mapping.query.Query
类名称：Query

Query介绍

[英]Models a query that can be executed against a data store.
[中]为可以针对数据存储执行的查询建模。
