В проекте, над которым я работаю, сейчас используется Hibernate версии 5.2.15.Final. При настройке кэша второго уровня проект использовал org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory
в качестве значения для hibernate.cache.region.factory_class
.
Когда я изменяю версию Hibernate на 5.3.12. Наконец, SingletonEhCacheRegionFactory
больше не находится вэтот пакет. Класс с тем же именем доступен в пакете net.sf.ehcache.hibernate
, и я могу использовать его без ошибок компиляции. Но если я запускаю его, я получаю сообщение об ошибке при попытке построить сеанс:
org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.cache.spi.RegionFactory]

Если я копаю глубже в трассировке стека, настоящая ошибка выглядит так:
