我尝试对 Activiti & Hibernate 使用通用事务管理器。他们有共同的数据库。我尝试先在 Hibernate 的帮助下保存同一个实体，然后在 Activiti 的帮助下保存：
Session session = ((SessionFactory) applicationContext.getBean("sessionFactory")).openSession();
session.beginTransaction();
session.save(client);
execution.setVariable("client", client);
session.getTransaction().commit();
session.close();
问题：
我在 activiti 的 ACT_RU_VARIABLE 表中没有看到任何客户实体的记录。
问题：
如何确保Activiti使用与Hibernate相同的事务？
添加：
