普通方法实现——远程方法调用RMI代码演示

1、spring_RMI01_server服务端

 package com.wisezone.service;

 import java.rmi.Remote;
 import java.rmi.RemoteException;

 public interface IHelloService extends Remote {

     public String sayHello(String msg) throws RemoteException;
 }

 package com.wisezone.service.impl;

 import java.rmi.RemoteException;
 import java.rmi.server.UnicastRemoteObject;

 import com.wisezone.service.IHelloService;

 public class HelloServiceImpl extends UnicastRemoteObject implements IHelloService{

     /**
      *
      */
     private static final long serialVersionUID = -4174742054186163053L;

     public HelloServiceImpl() throws RemoteException {

     }

     @Override
     public String sayHello(String msg) throws RemoteException {

         System.out.println("服务端接受消息："+msg);
         return "hello,"+msg;
     }

 }

 package com.wisezone.test;

 import java.net.MalformedURLException;
 import java.rmi.AlreadyBoundException;
 import java.rmi.Naming;
 import java.rmi.RemoteException;
 import java.rmi.registry.LocateRegistry;

 import com.wisezone.service.impl.HelloServiceImpl;

 /**
  * 发布顺序：先发布服务端，再发布客户端
  * @author 王东海

  */
 public class Publish {

     public static void main(String[] args) throws RemoteException, MalformedURLException, AlreadyBoundException {

         //设置端口
         LocateRegistry.createRegistry(8888);
         Naming.bind("rmi://127.0.0.1:8888/hello", new HelloServiceImpl());
         System.out.println("发布成功。。。");
     }
 }

2、spring_RMI01_client客户端

 package com.wisezone.service;

 import java.rmi.Remote;
 import java.rmi.RemoteException;

 public interface IHelloService extends Remote {

     public String sayHello(String msg) throws RemoteException;
 }

 package com.wisezone.test;

 import java.net.MalformedURLException;
 import java.rmi.Naming;
 import java.rmi.NotBoundException;
 import java.rmi.RemoteException;

 import com.wisezone.service.IHelloService;

 public class Test {

     public static void main(String[] args) throws MalformedURLException, RemoteException, NotBoundException {
         IHelloService helloService = (IHelloService) Naming.lookup("rmi://127.0.0.1:8888/hello");
         System.out.println("客户端接受消息："+helloService.sayHello("This is 5月1号劳动节"));
     }
 }

发布顺序：先发布服务端，再发布客户端

结果：
