Hibernate: No CurrentSessionContext configured

问题

I keep getting a :

HibernateException: No CurrentSessionContext configured!

in my code. The only information other searches that returned is that the culprit is:

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

in my hibernate.cfg.xml. I do have that in my hibernate.cfg.xml file, and I am running this in Tomcat 6. Does anyone know other possible causes?

回答1:

I believe you need to set your current_session_context_class to an actual class...I have my hibernate.cfg.xml configured for that as follows:

<property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>

The above code is used for a mySql database but i don't think it matters what type the database is for the above property

Hope this helps

回答2:

Both of these work in Hibernate 4+:

<property name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.current_session_context_class">org.hibernate.context.internal.ThreadLocalSessionContext</property>

In earlier version of Hibernate it used org.hibernate.context.ThreadLocalSessionContext (as shown in the other answers).

回答3:

In Hibernate 4.1.5 it is:

<property> name="hibernate.current_session_context_class">org.hibernate.context.internal.ThreadLocalSessionContext</property>

回答4:

I am using Hibernate 4 on tomcat 7 and the below property (the one mentioned in the question) worked for me.

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

回答5:

var config = new Configuration().Configure(); // Read config from hibernate.cfg.xml
config.CurrentSessionContext<WebSessionContext>(); // <-- No CurrentSessionContext fixing
return config.BuildSessionFactory();
