Нет сеанса Hibernate, связанного с потоком, и конфигурация не позволяет создавать не транзакционные данные здесь

Я получаю это исключение, когда я вызываю метод DAO, который использует SessionFactory.getCurrentSession(). Класс DAO аннотируется с помощью @Transactional, и у меня также есть <tx:annotation-driven/>, объявленный в файле конфигурации контекста приложения.

Я могу назвать свои методы DAO, которые выполняют запросы HQL, но всякий раз, когда я вызываю метод DAO, который сначала получает сессию Hibernate, я запускаю это исключение:

SEVERE: Failed to save the object.
org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

Мое приложение получает DAO из контекста приложения:

// load the Spring application context, get the DAOs
ApplicationContext applicationContext = new ClassPathXmlApplicationContext(new String[] { "dailyAveragingApplicationContext.xml" });
esrlDailyAvgDao = (EsrlDailyAvgDao) applicationContext.getBean("esrlDailyAvgDao");
esrlObservationsDao = (EsrlObservationsDao) applicationContext.getBean("esrlObservationsDao");

И возникает исключение, когда я пытаюсь сохранить объект:

esrlDailyAvgDao.saveOrUpdate(esrlDailyAvg);

Сам класс DAO использует аннотацию Transactional:

@Transactional
public class EsrlDailyAvgDaoHibernateImpl
    extends GenericDaoHibernateImpl<EsrlDailyAvg, Long>
    implements EsrlDailyAvgDao

Трассировка стека исключений выглядит следующим образом:
