@Transactional не работает, возможно, плохая конфигурация для sessionfactory.getCurrentSession()

У меня есть приложение spring при использовании Hibernate4, все работает с sessionFactory.openSession() в StageDaoImpl:

@Repository(value = "stageDao")
public class StageDaoImpl implements StageDao {

  @Autowired
  private SessionFactory sessionFactory;

  @Override
  public Integer editStage(Stage stage) {
    Session session = sessionFactory.openSession();
    Integer ban = 1;
    try {
        session.beginTransaction();
        session.update(stage);
        session.getTransaction().commit();
    } catch (HibernateException e) {
        ban = -1;
    } catch (Exception e) {
        ban = -2;
    } finally {
        session.close();
    }
    return ban;
  }

Я пытаюсь изменить editStage на аннотацию @Transactional, но я не знаю, как настроить транзакцию. Это всегда один и тот же результат.

@Repository(value = "stageDao")
public class StageDaoImpl implements StageDao {
  @Autowired
  private SessionFactory sessionFactory;

      @Override
      @Transactional
  public Integer editStage(Stage stage) {
    Session session = sessionFactory.getCurrentSession();
    Integer ban = 1;
    try {  
        session.update(stage);
    } catch (HibernateException e) {
        ban = -1;
    } catch (Exception e) {
        ban = -2;
    }
    return ban;
  }

Ошибка StackTrace:

 org.hibernate.HibernateException: No Session found for current thread
