I have problem with session in hibernate:

I've read something about this problem but the solutions don't work in my case.
My Dao class:
package com.myportal.portal.model;
import org.hibernate.classic.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import com.myportal.portal.entity.User;
@Repository
@Transactional(propagation=Propagation.REQUIRED)
public class HibernateDao {
@Autowired
private SessionFactory sessionFactory;
public HibernateDao()
{
}
public HibernateDao(SessionFactory sessionFactory)
{
this.sessionFactory = sessionFactory;
}
private Session getSessionFactory()
{
return sessionFactory.getCurrentSession();
}
private void setSessionFactory(SessionFactory sessionFactory)
{
this.sessionFactory = sessionFactory;
}
public void testowa()
{
User u = new User();
//SessionFactory sf = getSessionFactory();
//Session s = sf.openSession().beginTransaction()
// problem with this
Session session = getSessionFactory();
//session.save(u);
}
}

I use it like this:
@Controller
public class RegisterController {
@Autowired
private HibernateDao hibernateDao;
@RequestMapping(value="/register")
public String registerForm()
{
hibernateDao.testowa();
return "register";
}
}
How can I fix it?
I change DAO and create UserService, but error still appears :
DAO:
@Repository
public class HibernateDao {
@Autowired
private SessionFactory sessionFactory;
public HibernateDao()
{
}
public HibernateDao(SessionFactory sessionFactory)
{
this.sessionFactory = sessionFactory;
}
private Session getSessionFactory()
{
return sessionFactory.getCurrentSession();
}
private void setSessionFactory(SessionFactory sessionFactory)
{
this.sessionFactory = sessionFactory;
}
public void testowa()
{
User u = new User();
//SessionFactory sf = getSessionFactory();
//Session s = sf.openSession().beginTransaction()
// problem with this
Session session = getSessionFactory();
//session.save(u);
}
}
UserService:
@Service
public class UserService {
@Autowired
private HibernateDao hibernateDao;
@Transactional
public void addContact()
{
hibernateDao.testowa();
}
}
Controller:
@Controller
public class RegisterController {
@Autowired
private UserService userService;
@RequestMapping(value="/register")
public String registerForm()
{
userService.addContact();
return "register";
}
}
