java - WebLogic 上的序列化问题

转载 作者：行者123 更新时间：2023-12-01 05:21:09 24 4

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/
