позвольте мне описать, как это реализовано в нашем проекте.Мы используем AEM 6.3 с SP2.У нас есть следующие зависимости в корне pom.xml:
<!-- JPA -->

Затем у нас есть пакет для предоставления зависимостей JPA и сервис OSGI, который позволяет получить Hibernate Session.Пакет pom.xml

В комплекте есть следующий сервис:
package com.myproject.db;
import org.hibernate.Session;
public interface JPASessionFactory {
Session openSession();
void closeSession(Session session);
}
