一个超级简单rmi通信的实例

RmiServer

public class RmiServer {
    
    public static void main(String[] args) {
        try {
            ISayHello iSayHello = new SayHelloImpl();
            LocateRegistry.createRegistry(8888);
            Naming.bind("rmi://localhost:8888/xxx", iSayHello);
            System.out.println("server start success!!!");
        } catch (RemoteException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (AlreadyBoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
