Hibernate SessionFactory与EntityManagerFactory [英] Hibernate SessionFactory vs. EntityManagerFactory

问题描述

我是Hibernate的新手，并且不清楚是使用 SessionFactory 还是 EntityManagerFactory 来获取hibernate会话。两者有什么区别？优点& Cons

解决方案

首选 EntityManagerFactory 和 EntityManager 。它们由JPA标准定义。

$ b

SessionFactory 和 Session 是hibernate特有的。 EntityManager 会在后台调用hibernate会话。如果您需要一些在 EntityManager 中不可用的特定功能，您可以通过调用以下方式获取会话：

  Session session = entityManager.unwrap（Session.class）; 
  

I am new to Hibernate and am unclear of whether to use a SessionFactory or EntityManagerFactory to obtain the hibernate session. What is the difference between the two? Pros & Cons?

解决方案

Prefer EntityManagerFactory and EntityManager. They are defined by the JPA standard.

SessionFactory and Session are hibernate-specific. The EntityManager invokes the hibernate session under the hood. And if you need some specific features that are not available in the EntityManager, you can obtain the session by calling:

Session session = entityManager.unwrap(Session.class);
