本文整理了Java中org.hibernate.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.hibernate.query.Query
类名称：Query

Query介绍

[英]Represents an HQL/JPQL query or a compiled Criteria query. Also acts as the Hibernate extension to the JPA Query/TypedQuery contract

NOTE: org.hibernate.Query is deprecated, and slated for removal in 6.0. For the time being we leave all methods defined on org.hibernate.Queryrather than here because it was previously the public API so we want to leave that unchanged in 5.x. For 6.0 we will move those methods here and then delete that class.
[中]表示HQL/JPQL查询或编译条件查询。还充当JPA查询/TypedQuery合同的Hibernate扩展
注：org。冬眠查询已弃用，并计划在6.0中删除。目前，我们将所有方法都留在org上定义。冬眠Queryrather比这里更重要，因为它以前是公共API，所以我们希望在5年内保持不变。x、 对于6.0，我们将把这些方法移到这里，然后删除该类。
