Is that a good approch to manage hibernate session?


I am looking for a good way to manage hibernate session across web application. My problem is that i dont want to allow session access in the view or API layer. so i built the following method in my abstract BaseDao class. the method method

protected static Session getSession() {
    if(!session.isOpen()){
        session = sessionFactory.openSession();
    }else{
        session.clear();
    }
    return session;
}

usage:

public IHibernateBean save(IHibernateBean bean) {
    Transaction t = session.beginTransaction();
    getSession().saveOrUpdate(bean);
    t.commit();
    return bean;
}

public IHibernateBean getByPK(Class<?> class1 , Long pk) {
    IHibernateBean hibernateBean = (IHibernateBean) getSession().get( class1 , pk );
    return hibernateBean;
}

I'd echo axtavt's answer. Just as an additional information, if you are using a Java EE capable container (like JBoss AS), then use the EntityManager which is managed by it. It's specially easy in Java EE 6, with CDI.

You can use the contextual session obtained via SessionFactory.getCurrentSession(), see 2.3. Contextual sessions.

Also see Generic Data Access Objects for example of typesafe DAO implementation.
