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

 */
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：
