包路径：javax.persistence.criteria.Subquery
类名称：Subquery
方法名：groupBy

Subquery.groupBy介绍

[英]Specify the expressions that are used to form groups over the subquery results. Replaces the previous specified grouping expressions, if any. If no grouping expressions are specified, any previously added grouping expressions are simply removed. This method only overrides the return type of the corresponding AbstractQuery method.
[中]指定用于在子查询结果上形成组的表达式。替换以前指定的分组表达式（如果有）。如果未指定分组表达式，则只需删除之前添加的任何分组表达式。此方法仅覆盖相应AbstractQuery方法的返回类型。
