Настраиваю Hibernate средствами Spring.

При запуске теста для DAO-бина получаю иксепшен:

Код


Exception in thread "main" org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed

Хотя открытие сессии должен обеспечивать сконфигурированный SessionFactory.
Вот конфиг spring-hibernate.xml, в котором все настраивается
