Both getCurrentSession() and openSession() are method of SessionFactory.
openSession() Method
- It always creates a new Session object.
- Programmer need to explicitly flush and close session objects.
- openSession() is slower than getCurrentSession() in single threaded environment.
- You do not need to configure any property to call this method.
getCurrentSession() Method
- It creates a new Session iff there is no any session in current hibernate context.
- Programmer do not need to flush and close session objects, it will be taken care by Hibernate internally.
- In single threaded environment it is faster than openSession().
- You need to configure additional property in hibernate.cfg.xml file <property name=”hibernate.current_session_context_class”>thread</property> otherwise it will throw an exception.
