Error: org. hibernate. hibernateexception: No currentsessioncontext configured!

Version: hibernate_core 3.3.2
Use SF. opensession ();
But now getcurrentsession () is popular. The reason is very simple. opensession () re-starts a session regardless of the situation, while getcurrentsession () adds a judgment, when there is a session, it will be called directly. If there is no session, it will be created. The benefits are obvious!
Error message I met

Check the error message: the current sessioncontext is not configured!
Haha. I searched the internet. It turns out that
In an environment integrated with hibernate (such as JBoss), add the following to the session-factory section in hibernate. cfg. xml:

XML code :{
DP. Sh. toolbar. copytoclipboard (this); Return false;
} "Href =" # ">

1. <PropertyName = "current_session_context_class">JTA</Property>

<property name="current_session_context_class">jta</property>

In an environment without hibernate integration (for example, a JDBC Independent Application), add the following to the session-factory segment in hibernate. cfg. xml:

 

XML code :{
DP. Sh. toolbar. copytoclipboard (this); Return false;
} "Href =" # ">

1. <PropertyName = "current_session_context_class">Thread</Property>

<property name="current_session_context_class">thread</property>

Now use the getcurrentsession () method to get the session. No error is returned.
