休眠会话关闭

问题描述

我只是遵循一个简单的hibernate struts教程，并通过hibernate成功完成了数据库调用。但是，我没有看到代码关闭任何地方的休眠连接。

  sessionFactory.getCurrentSession（）; 
  

用于获取每个请求的会话。我应该在用户注销时关闭此会话吗？或者在每次请求之后，这个东西是否被框架照顾？第二个相关的问题是，在什么样的用例中我会使用hibernate会话拦截器？

和第三个问题（对不起，它只是在我脑海中弹出）用hibernate / struts2缓存的最佳选择是什么？

解决方案

关于第一个问题，说：

关于第三个问题，Struts2是一个表示框架。它与持久性实体无关并因此缓存持久性实体。 详细介绍了第二级缓存。

正如你所看到的，文档中有很多有趣的信息。我会建议阅读它。

I just followed a simple hibernate struts tutorial and succesfully made db calls through hibernate. However I don't see the code closing the hibernate connection anywhere.

sessionFactory.getCurrentSession();

is used to get the session per request. Should I close this session when the user logs out? or after each request of is this something taken care of by the framework?

a second related question is, In what kind of use case would I use a hibernate session interceptor?

and a third question(sorry it just popped in my mind) what the best option for caching with hibernate/struts2?

解决方案

Regarding the first question, the reference documentation says:

Regarding your second question, the documentation says:

Regarding the third question, Struts2 is a presentation framework. It has nothing to do with persistence and thus caching of the persistent entities. The documentation talks in details about the second-level cache.

As you see, the documentation has a whole lot of interesting information. I would advise reading it.
