    public static void main(String[] args) throws RemoteException {
        ISayHelloService sayHelloService = new SayHelloService();
        UnicastRemoteObject.exportObject(sayHelloService, 0);
        LocateRegistry.createRegistry(1099).rebind("SayHello", sayHelloService);
    }


    static class SayHelloService implements ISayHelloService {
        @Override

public class RmiClient {
    public static void main(String[] args) throws RemoteException, NotBoundException {
        // RMI默认端口1099，不需要显式声明
        Registry registry = LocateRegistry.getRegistry();
        ISayHelloService sayHelloService = (ISayHelloService) registry.lookup("SayHello");
        System.out.println(sayHelloService.hello("word"));
