java的Socket编程实现客户端与服务端的通信-----------实现客户端与服务端对象的互通

创建好对象（必须序列化；也就是实现Serializable这个接口，只有序列化了才可以进入流实现想要的操作），服务端，客户端分别使用ObjectInputStream（对象输入流）,ObjectOutputStream,（对象输出流）进行读写，实现客-服对象互通；简单的实现如下

import java.io.Serializable;

//implements Serializable实现这个接口,代表我们这个对象做了序列化 ;
	//商品信息的实体类
public class Shop implements Serializable {

	
	public  Shop(int numb,String name) {
		super();
		this.numb=numb;
		this.name=name;
		
		
	}
	private   int numb;
	private  String name;
	
	public int getNumb() {
		return numb;
	}

	public void setNumb(int numb) {
		this.numb = numb;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	@Override
	public String toString() {//重写toString更方便打印
		return "Shop [numb=" + numb + ", name=" + name + "]";
	}

	}

import java.io.IOException;
import java.io.InputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
import java.util.List;
	
	
	//implements Serializable实现这个接口,代表我们这个对象做了序列化 ;做了序列化,这个对象就能够在网络世界里面穿梭
	//商品信息的实体类
public class Threads {
	
	 public static void main(String[] args) {
		 // Server-Object
		 
		 Shop shop1 = new Shop(101,"美滋滋");
		 Shop shop2 =new Shop(102,"乐呵呵");
			
		List <Shop>list =new ArrayList<Shop>();
		list.add(shop1);
		list.add(shop2);
		
			try {
				
				ServerSocket st = new ServerSocket(8888);
				System.out.println("这里服务器准备好了，等待服务端的接入·······");
				
				Socket socket = st.accept();
				
				
				OutputStream os = socket.getOutputStream();
				ObjectOutputStream ops = new ObjectOutputStream(os);
				
				ops.writeObject(list);
				
				System.out.println("已接入客户端："+socket.getInetAddress());
				
				InputStream is = socket.getInputStream();
				ObjectInputStream ois = new ObjectInputStream(is);
				
			
				Object oj =ois.readObject();
				
				List<Shop>list1 =(List)oj;
				
				System.out.println("客户说："+oj);
				System.out.println("以上是接收到的信息");
				
				socket.close();
				ops.flush();
				
			}catch(IOException e) { 
				
				
			} catch (ClassNotFoundException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} 
			

		}
