Нет EntityManager с фактической транзакцией, доступной для текущего потока с использованием Spring MVC и JPA Eclipselinl ⇐ JAVA

[Anonymous]

Я настраиваю свой проект и пробовал решения, упомянутые здесь и там, но все равно получаю ту же ошибку. Только с @PersistenceContext(type=PersistenceContextType.EXTENDED) я не получаю исключений, но не отражает операции обновления/сохранения/удаления.
