遗留的Criteria API仍然被推荐？ [英] Is legacy Criteria API still recommended?

问题描述

我的团队在Hibernate 3.x下一直使用hibernate Criteria API。最近，我们希望将Hibernate版本升级到5，但Criteria API似乎不再被推荐。但JPA看起来像一个完全不同的API，我们不想冒险。我们应该继续使用旧的Criteria吗？

My team has been using hibernate Criteria API for a long time under Hibernate 3.x. Recently, we want to upgrade Hibernate version to 5, but the Criteria API seemed not be recommended any more. But JPA looks like a totally different API which we don't want to risk. Should we keep using the old Criteria?

推荐答案

好吧，版本5.0标准章节相当不错：

Hibernate提供了一个旧的，遗留的org.hibernate.Criteria API，它应该被视为弃用。没有功能开发将针对这些API。最终，Hibernate特定的标准功能将作为JPA javax.persistence.criteria.CriteriaQuery的扩展移植。有关org.hibernate.Criteria API的详细信息，请参阅Legacy Hibernate Criteria Queries。

Hibernate offers an older, legacy org.hibernate.Criteria API which should be considered deprecated. No feature development will target those APIs. Eventually, Hibernate-specific criteria features will be ported as extensions to the JPA javax.persistence.criteria.CriteriaQuery. For details on the org.hibernate.Criteria API, see Legacy Hibernate Criteria Queries.

还有更多：

较早的Hibernate org.hibernate.Criteria查询API的用户将认识到一般的方法，尽管我们相信JPA API更加优秀，从该API中吸取的经验教训。

Users of the older Hibernate org.hibernate.Criteria query API will recognize the general approach, though we believe the JPA API to be superior as it represents a clean look at the lessons learned from that API.

所以，它看起来真的取决于您的团队。我花了一段时间才习惯JPA API，但现在已经非常顺利。为了获得非常大的读取性能，我放弃了Hibernate，但通常我没有任何使用JPA的问题。如果我需要更动态的东西，我倾向于使用 @NamedQueries 作为基本的acccess，而 Criteria API。

So, it seems like it's really up to your team. It took me a while to get used to the JPA API, but it's pretty smooth sailing now. I have dropped back into Hibernate for performance for very large fetches, but in general I'm not having any problem using anything JPA. I tend to use @NamedQueries for basic acccess, and the Criteria API if I need something more dynamic.

编辑：更新我能解决性能问题，现在应用程序严格为JPA。

Update I was able to resolve the performance issue and the application is strictly JPA now.
