java - RMI Java | IP 绑定(bind)问题和安全管理器问题

Question

问题 1已解决!

我对以下问题感到困惑，我正在为我的学校做一个关于 Java 中的 RMI 的项目，我将一个对象放入 RMIRegistery

public static void bindObjectToRMIRegistry(Object obj,String name) throws AccessException, RemoteException {
    System.out.println("<< IN ServerHelper.bindObjectToRMIRegistry() >>");
    if(getRMIRegistru() != null) {
        System.out.println("Binding to registry: "+getRMIRegistru().toString());
        getRMIRegistru().rebind(name, (Remote) obj);
    }else {
        System.out.println("No registry to bind");
    }
}

在日志中我收到以下消息:

Binding to registry: RegistryImpl_Stub[UnicastRef [liveRef: [endpoint:192.168.56.1:9005,objID:[0:0:0, 0]]]]

The port is good 9005, but the IP, it's not the good one and I have no ideea where does he get this IP. I also tried to set the HOST for rmi to my localhost 192.168.1.2 but it keeps using this address 192.168.56.1:9005

配置中是否缺少某些内容？

问题2

Registry registery = LocateRegistry.getRegistry("192.168.1.2",9005);
IHello hi = (IHello) registery.lookup("HI");

我得到:RemoteException 错误:错误解码返回；嵌套异常是: java.lang.ClassNotFoundException:Interfaces.IHello(无安全管理器:禁用 RMI 类加载器)

Answer 1

您很可能有多个网络接口(interface)，例如LAN、WLAN、用于处理虚拟机的虚拟等。您可以通过运行 ipconfig (Windows) 或 ifconfig (Linux) 进行检查。

绑定(bind)RMI时指定正确的IP。如果你有多个，Java 无法猜测你想要哪一个:

Naming.rebind("//192.168.1.2/rmi", new RMI());
