Question

从v5迁移到Drools 6.2.0.Final，我遇到了JPA持久性问题。环境：由Spring管理的JTA事务。

环境配置：

// transaction manager is a Spring JTATransactionManager. This seems to activate the KieSpringTransactionManager/KieSpringJpaManager
env.set(EnvironmentName.TRANSACTION_MANAGER, transactionManager);
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, entityManagerFactory);

似乎TriggerUpdateTransactionSynchronization.beforeCompletion（）方法访问EntityManager以检索会话的对象。但是，这个实体管理器已经被Spring在它自己的beforeCompletion事务同步中关闭，因此是例外。

这是正常行为吗？我做错了吗？

任何帮助表示感谢。
