我正在使用两个消息驱动器Bean（MDB）更新同一张表。我正在使用EJB 3.0并将事务类型用作@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
有时，其中一种方法会出现错误，例如“事务因超时而终止”，并且MDB被停用。因此，我必须重新启动服务器。
我可以使用任何其他类型的事务属性@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)来避免超时错误吗？
这是我的堆栈跟踪。[:] CWWMQ0007W: The message endpoint Rsme#RsmeEJB.jar#GemsInqMDB has been paused by the system. Message delivery failed to the endpoint more than 0 times.

最佳答案
创建具有相同结构的两个不同表以避免死锁，而不是对两个MDB使用相同表
关于java - 由于使用两个消息驱动器Bean更新同一表而导致的超时导致事务结束，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25502939/
