What is the role of HibernateUtil?

提问by Dino

I'm new to Hibernate, and everytime I come across a Hibernate tutorial there is a mention of HibernateUtil class ?

我是 Hibernate 的新手，每次我遇到 Hibernate 教程时都会提到 HibernateUtil 类？

What actually does it do ? And if there is a standard implementation why don't it being included in Hibernate jar itself?

它实际上有什么作用？如果有一个标准的实现，为什么不将它包含在 Hibernate jar 本身中呢？

There's an answer herethat might suffice.

有一个答案在这里可能就足够了。

Looks like they want developers to write their own by design, because the number of possibilities to cover is too large.

看起来他们希望开发人员按设计编写自己的代码，因为要涵盖的可能性太多了。
