java - 异常 "remote object implements illegal remote interface"？

Question

我在 Java 中使用 rmi。但是有一个 ExportException“远程对象实现非法远程接口(interface)”。

这是我的代码，有人可以帮帮我吗？

public interface RemotePeer extends Remote {

    public abstract void displayInf(String inf);

    public abstract void exit();

    public abstract boolean isActive();
}


 public class Peer implements RemotePeer{
        public Peer(){}
        ....

        public static void main(String[] args) {
           Peer p=new Peer()
           RemotePeer remoteP=(RemotePeer) UnicastRemoteObject.exportObject(p, 0);
           Registry registry = LocateRegistry.getRegistry();
           }
}

Remote 接口(interface)中的每个方法都必须能够抛出 RemoteException。你的界面应该是:

public interface RemotePeer extends Remote {

    public abstract void displayInf(String inf) throws RemoteException;

    public abstract void exit() throws RemoteException;

    public abstract boolean isActive() throws RemoteException;
}
