如何rmi运行java程序？

首先在server端需要一个接口，继承自java.rmi.Remote public interface Hello extends Remote { public void say() throws RemoteException; } 其次实现这个接口并继承java.rmi.server.UnicastRemoteObject public class SayHello extends UnicastRemoteObject implements Hello{ protected SayHello() throws RemoteException{ super(); } public String say() throws RemoteException { return "Hello"; } } 接着注册服务，绑定端口 public class Reg { public static void main(String[] args) throws RemoteException,MalformedURLException{ LocateRegistry.createRegistry(1099); SayHello sh = new SayHello(); Naming.rebind("rmi://localhost:1099/sh", sh); System.out.println("注册完毕"); } } 然后在客户端 public class Client { public static void main(String[] args) throws RemoteException,MalformedURLException,NotBoundException{ Hello h = (Hello)Naming.lookup("rmi://localhost:1099/sh"); System.out.println(h.say()); } } 即可
