Java RMI简单示例程序

1.         编写接口

import java.rmi.*;
 
public interface HelloIn extends java.rmi.Remote{
String sayHello() throws RemoteException;
}

 

 

        

2.         实现远程接口

import java.rmi.*;
import java.net.*;
import java.rmi.registry.*;
import java.rmi.server.*;
 
public class Hello extends java.rmi.server.UnicastRemoteObject implements HelloIn {
        public Hello() throws RemoteException{
                super();
        }
        public String sayHello() throws RemoteException{
                return "Hello,World!";
        }
        public static void main(String[] args){
                try {
                        Hello h=new Hello();
                        java.rmi.Naming.rebind("hello",h);
                        System.out.print("Ready......");
                } catch(Exception e) {
                        e.printStackTrace();
                }
        }
}

 

 

        

3.         客户端程序

import java.rmi.*;
import java.rmi.registry.*;
 
public class Helloworld{
        public static void main(String[] args){
                try{
                        HelloIn hi=(HelloIn)Naming.lookup("//localhost/hello");
                        for(int i=0;i<10;i++){
                                System.out.println(hi.sayHello());
                        }
                } catch(Exception e) {
                        e.printStackTrace();
                }
       }
}
