当我在本地服务器(Jetty)上运行代码时，我的一个类没有实现可序列化，当时它运行良好。(如果没有实现可序列化，代码在本地服务器上运行良好)
但是当我将它部署在 weblogic 上时，它给出的错误为:
Caused by: java.rmi.UnmarshalException:
当我为该特定类实现 Serialized 时，WebLogic 上的错误就消失了。
知道为什么会发生这种情况吗？

最佳答案
此错误是因为在存在多个服务器的情况下，WebLogic 实际上正在序列化远程调用的对象，而 Jetty 则不会序列化，而是使用 EJB 本地接口(interface)。
关于java - WebLogic 上的序列化问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10394964/
