java socket - 传递对象

Person类：

package com.zhyea.olproxy.socket;

import java.io.Serializable;

public class Person implements Serializable {
    
    private static final long serialVersionUID = 3199890860738953693L;
    /**
     * 姓名
     */
    private String name;
    /**
     * 年龄
     */
    private int age;
    
    public Person(String name, int age){
        this.name = name;
        this.age = age;
    }
    
    
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    
    
}

服务端：

package com.zhyea.olproxy.socket;

import java.io.IOException;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;

public class Server {

    public static ArrayList<Socket> socketList = new ArrayList<Socket>();
    
    public static void main(String[] args){
        try {
            //创建一个ServerSocket，用以监听客户端Socket的请求
            ServerSocket serverSocket = new ServerSocket(49000);
            while(true){
                //接收到客户端的请求后，服务器端也产生一个socket
                Socket socket = serverSocket.accept();
                ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
                Person person = new Person("Robin", 16);
                oos.writeObject(person);
                //关闭输出流，关闭socket
                oos.close();
                socket.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
}

客户端：

package com.zhyea.olproxy.socket;

import java.io.ObjectInputStream;
import java.net.Socket;

public class Client {

    public static void main(String[] args){
        try {
            Socket socket = new Socket("127.0.0.1", 49000);
            ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
            Person robin = (Person)ois.readObject();
            
            if(null!=robin)System.out.println(robin.getName() + "##" + robin.getAge());
            
            ois.close();
            socket.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

有两点需要注意

• 对象类需要实现Serializable接口；
• 通信流使用ObjectOutputStream 和ObjectInputStream 来处理。
