我有一个RMI服务器和一个桌面RMI客户端。当我重新启动服务器时,我在客户端遇到错误。是否可以在不重新启动客户端的情况下重新启动RMI连接?服务器重启后重新连接RMI客户端

你得到了什么样的错误? – akf

当服务器被终止,您将收到的ConnectException。之后,您可以使用Naming.lookup来获取新的服务器对象。

如果服务器重新启动,您可能会得到一个'NoSuchObjectException'。 – EJP

如果您使用的是Spring(即RmiProxyFactoryBean),则可以简单地将属性refreshStubOnConnectFailure设置为true,并且该bean将在服务器重新启动后继续存在。

<property name="refreshStubOnConnectFailure" value="true" />
