XAResource 恢复信息不可序列化

Question

我们在运行 UI 工作流时在应用程序中看到以下异常，它会阻止用户执行任务。到目前为止无法找到此错误的根本原因，但我们在 prod 中使用的解决方法是反弹 JVM，问题就消失了。

第一次报告事件 - 由于在ibatis mapper类中执行SELECT COUNT SQL时发生了“not serializable”异常，我们让ibatis对象（AlertInboxExample）实现了可序列化。在调用映射器方法 countByExample() 时，同样的对象 (AlertInboxExample) 作为方法参数传递。但是这种更改并没有解决问题并得到同样的异常。

 while trying to enlist resources from DataSource jdbc/ATDatabaseXA with the Transaction Manager for the current transaction, and threw a ResourceException.

我很难理解这个 XA 恢复流程是如何工作的。需要您的帮助来了解此异常以及查找此非序列化对象的方法。

谢谢！

Answer 1

我能想到用户（在这种情况下是应用程序或 ibatis 或 spring）可能能够中断 XA 恢复的序列化的唯一方法是切换线程上的类加载器，这样就不可能了加载 WebSphere Application Server 类。事务管理器进行抢先反序列化以确保 XA 恢复信息可以在以后反序列化。更改类加载器可能会破坏它，所以我首先检查应用程序或 ibatis 或 spring 代码（如果你知道的话）是否可以切换类加载器。否则，这似乎是应用程序服务器中的一个错误，您应该按照 Andy 的建议打开 PMR。
