java.io.NotSerializableException:org.jboss.web.tomcat.service.WebAppClassLoader

当我试图在jboss集群中部署我的应用程序时，我遇到了这个异常。我们可以序列化webAppClassLoader吗？有人能帮我解决这个问题吗。提前感谢。下面是完整的堆栈供您参考

老实说，我认为对这些对象（类装入器、工厂等）进行集群没有任何意义。它们不是应用程序状态，而是“程序逻辑的一部分”

应用程序中的其他节点应该具有相同的程序代码，因此无需在集群中复制

您可能想要复制的是，例如，应该在类加载器上加载的类的名称（如果这是由用户输入动态计算的）。或者，如果这是某种url类加载器，则是从中下载类的url

---

尝试更好地隔离应用程序中的业务状态（例如购物车的内容），并将序列化和复制限制在此范围内。

为什么要序列化类加载器？这是我的应用程序要求。当我尝试应用程序的会话复制时，出现了几个不可序列化的错误，我将大多数文件设置为可序列化的，包括defaultlistablebeanfactory、classpathresource、runtimebeanreference、methodoverrides、constructorargumentvalues等。最后我在这一点上发了言。对于会话复制，我认为我们必须序列化必要的类。在spring3.x中，bean工厂是可序列化的，而spring2.5.6中没有。我正试图使整个bean工厂可以序列化，因为我得到了可序列化的异常。谢谢你的回复。。
