重新RMI客户端服务器重新启动后(Reconnect RMI client after server

我有一个RMI服务器和桌面客户端RMI。 当我重新启动服务器，我得到的客户端错误。 是否有可能重新启动，无需重新启动客户端RMI连接？

Answer 1:

当服务器被终止，您将收到的ConnectException。 之后，你可以只使用Naming.lookup得到一个新的服务器对象。

Answer 2:

如果你使用Spring（即RmiProxyFactoryBean ），可以将属性简单地设定refreshStubOnConnectFailure到true和bean将生存的重新启动服务器。

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