I an using Spring 3.1 + Hibernate 4.x in my web application. In my DAO, i am saving User type object as following
sessionFactory.getCurrentSession().save(user);
But getting following exception:
org.hibernate.HibernateException: save is not valid without active transaction
I googled and found similar question on SO, with following solution:
Session session=getSessionFactory().getCurrentSession();
Transaction trans=session.beginTransaction();
session.save(entity);
trans.commit();
That solves the problem. But in that solution, there is lot of mess of beginning and committing the transactions manually.
Can't i use sessionFactory.getCurrentSession().save(user); directly without begin/commit of transactions manually?
I try to use @Transactional on my service/dao methods too, but the problem persists.
EDIT : Here is my Spring Config File:
