使用 JPA 的 Spring 事务在 AfterCompletion 阶段抛出异常

Question

我有一个 Web 应用程序，它使用 Spring Framework (3.1) 并通过由 Hibernate (4.1.1) 支持的 JPA (2.0) 进行持久性

还启用了休眠搜索 (4.1 RC)。 Hibernate 的二级缓存是 Infinispan (5.1.3)。

我还使用 Infinispan 作为 Lucene (3.5) Directory Provider（用于 Hibernate Search）。

一切都通过 XA 事务运行，Bitronix (2.1.2) 作为 JTA 管理器。

我有用@Transactional 注释的方法。当方法结束，事务提交时，会发生以下异常：

您会注意到 Hibernate 类“SynchronizationRegistryImpl”。这个拥有一组javax.transaction.Synchronization 对象。我认为正在发生的是 Hibernate 本身在这个集合中注册为同步。所以，

1. 提交后，会触发两个事件：beforeTransactionCompletion 和 afterTransactionCompletion。
2. beforeTransactionCompletion 进展顺利。
3. afterTransactionCompletation 启动并调用方法 notifySynchronizationsAfterTransactionCompletion。
4. 此方法在 Set 的每个 Synchronization 元素上调用 afterCompletion。
5. 集合中的一项（不是最后一项）是 Hibernate 项，需要进行一些清理。
6. 此清理会清空 Set。
7. ConcurrentModificationException 被抛出，因为该集合在迭代时被清理。

也许我错误地配置了 Hibernate。我的 Spring XML 太大了，不能放在这里。幸运的是，你们中的一些人知道为什么会发生这种情况。

更多数据（可能有用也可能没用）来建立上下文：

• 同步集中的其他项目属于休眠搜索。
• 数据库数据源为 PostgreSQL。
• 我使用 XA 是因为事务中还有一个 ActiveMQ JMS，而且起初 Infinispan 也被设置为 XA 资源（现在它与 JTA 同步挂钩）。
• Spring Security 已启用。
• Hibernate 通过 CMTTransactionFactory 连接到 JTA。
• 我不确定 PersistenceContext 是“事务性的”还是“扩展的”，但从调试来看，它看起来像后者。

Answer 1

原来需要更多的 Infinispan 配置，而我不知道它存在。 在事务标签中（默认配置下），即使我设置了事务管理器查找，我也必须明确添加属性transactionMode="TRANSACTIONAL"。

我还使用了 Hibernate 使用的缓存的默认配置，它们的名称是：entity、local-query 和 timestamp . hibernate-infinispan.jar 中有一个名为 infinispan-configs.xml 的文件，它有助于设置所需的配置。

更新：忽略这个答案。问题又出现了，就是这个bug。
