No session currently bound to execution context

I got below exception when I used session.getCurrentSession().

I have mentioned 

hibernate.current_session_context_class: managed

org.hibernate.HibernateException: No session currently bound to execution context
    at org.hibernate.context.internal.ManagedSessionContext.currentSession(ManagedSessionContext.java:75)
    at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:1014)
    at io.dropwizard.hibernate.AbstractDAO.currentSession(AbstractDAO.java:36)
    at io.dropwizard.hibernate.AbstractDAO.persist(AbstractDAO.java:149)

I use this with dropwizard. Can anyone help me to solve this?

If you are using Dropwizard Hibernate. You need to add @UnitOfWork annotation to your Resource method. More info within dropwizard manual, hibernate chapter.

Can you try with : session.openSession() - It tell hibernate to always opens a new session and you have to close once you are done with the operations. With session.getCurrentSession(), hibernate returns a session bound to a context that you don't need to close and only need to set the hibernate.current_session_context_class to thread.

You can also configure session with SpringSessionContext, if your application is Spring based.

Edit your hibernate-cfg.xml with below line:

hibernate.current_session_context_class=org.springframework.orm.hibernate3.SpringSessionContext

What above line will do?

Making session context class as "org.springframework.orm.hibernate3.SpringSessionContext ", Hibernate will assume it is executing inside of a Spring transactional context (i.e. through a Spring transactional aspect) and Spring will now manage your transaction for you. However if you call getCurrentSession() outside of such a context, Hibernate will throw an exception complaining that no Session is bound to the thread.
