Why HibernateTemplate isn’t recommended? [duplicate]

by

Because its main goal was to get a Hibernate session tied to the current Spring transaction, when SessionFactory.getCurrentSession() didn’t exist. Since it now exists (and for a long time: HibenateTemplate usage is discouraged even in the hibernate3 package), there is no reason to use this Spring-specific class instead of using SessionFactory.getCurrentSession() to get a session tied to the current Spring transaction.

If you use Spring, then you should use its declarative transaction management, which allows you to avoid opening, committing, closing and flushing. It’s all done by Spring automatically:

@Autowired
private SessionFactory sessionFactory;

@Transactional
public void someMethod() {
    // get the session for the current transaction:
    Session session = sessionFactory.getCurrentSession();
    // do things with the session (queries, merges, persists, etc.)
}

In the above example, a transaction will be started (if not already started) before the method invocation; A session will be created by Spring for the transaction, and the session will be automatically flushed before the commit of the transaction, that will be done by Spring automatically when the method returns.
