No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

Question

I am getting this exception when I call a DAO method which uses SessionFactory.getCurrentSession(). The DAO class is annotated with @Transactional

Answer 1

I got the following error:

org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
    at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)

I fixed this by changing my hibernate properties file

hibernate.current_session_context_class=thread

My code and configuration file as follows

session =  getHibernateTemplate().getSessionFactory().getCurrentSession();

session.beginTransaction();

session.createQuery(Qry).executeUpdate();

session.getTransaction().commit();

on properties file

hibernate.dialect=org.hibernate.dialect.MySQLDialect

hibernate.show_sql=true

hibernate.query_factory_class=org.hibernate.hql.ast.ASTQueryTranslatorFactory

hibernate.current_session_context_class=thread

on cofiguration file

<properties>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>         
<prop key="hibernate.query.factory_class">${hibernate.query_factory_class}</prop>       
<prop key="hibernate.generate_statistics">true</prop>
<prop key="hibernate.current_session_context_class">${hibernate.current_session_context_class}</prop>
</props>
</property>
</properties>

Thanks,

Answer 2

after I add the property:

<prop key="hibernate.current_session_context_class">thread</prop> I get the exception like:

org.hibernate.HibernateException: createQuery is not valid without active transaction
org.hibernate.HibernateException: save is not valid without active transaction.

so I think setting that property is not a good solution.

finally I solve "No Hibernate Session bound to thread" problem :

1.<!-- <prop key="hibernate.current_session_context_class">thread</prop> -->
2.add <tx:annotation-driven /> to servlet-context.xml or dispatcher-servlet.xml
3.add @Transactional after @Service and @Repository

Answer 3

I had the same issue today.While searching here for solution,I have did silly mistake that is instead of importing

import org.springframework.transaction.annotation.Transactional;

unknowingly i have imported

import javax.transaction.Transactional;

Afer changing it everything worked fine.

So thought of sharing,If somebody does same mistake .

Whenever you will face below error just follow it.

org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)

Put a @Transactional annotation for each method of implementing classes.

Answer 5

You are missing <context:annotation-config /> from your spring context so the annotations are not being scanned!

Answer 6

You can have the @Transactional in the child class, but you have to override each of the methods and call the super method in order to get it to work.

Example:

@Transactional(readOnly = true)
public class Bob<SomeClass> {
   @Override
   public SomeClass getValue() {
       return super.getValue();
   }
}

This allows it to set it up for each of the methods it's needed for.
