我在 RMI 上遇到问题：

我的 RMI-Client 尝试获取 192.168.1.37 的注册表

Registry registry = LocateRegistry.getRegistry("192.168.1.37",1099);
String[] s = registry.list();
    for( String obj : s ) {
        System.out.println("  " + obj);
    }
IMaster master = (IMaster) registry.lookup ("rmi://192.168.1.37:1099/Master");

我的 RMI 服务器看起来像这样：

Registry registry = LocateRegistry.getRegistry();
IMaster m = new Master(3, 3);
registry.rebind ("Master", m);
System.out.println ("Master Server is ready.");

注册表列表 [String[] s = registry.list();] 知道“主”绑定。这意味着：网络上没有问题并且注册表存在。该对象也已导出。（我为 RMI 使用了一个 Eclipse 插件）。

但是在客户端的查找行中，我遇到了一个异常：

有谁知道如何解决这个问题？：） 谢谢

尝试改变

IMaster master = (IMaster) registry.lookup ("rmi://192.168.1.37:1099/Master");

至

IMaster master = (IMaster) registry.lookup ("Master");

服务器不知道自己的 IP。所以你必须通过告诉他你的服务器的ip来启动它。

我使用 Eclipse 插件：genady

所以在eclipse中的服务器上：点击“Run Configurations...”->“RMI VM Properties”并将该IP添加到“java.rmi.server.hostname”

和：

IMaster master = (IMaster) registry.lookup ("Master");

就这样。谢谢你的帮助:)
