基于Tcp/ip Scoket套接字实现类似 QQ聊天-优快云博客

QQServer 服务器端

QQServer.java

package com.net; 

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

/**

 * @version 创建时间：2013-5-25 下午8:25:15 
 * 
 */
public class QQServer {

	public static void main(String[] args) {
		try {
			ServerSocket server = new ServerSocket(8000);
//			服务器一直接收socket的连接，一旦有socket连接，就会产生一个新的线程和端口来运行这个新的socket
			while(true)
			{
				Socket socket = server.accept();
				new InputStreamThread(socket).start();
				new OutputStreamThread(socket).start();
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

QQClient 客户端

QQClient.java

package com.net; 

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;

/** 
 * @author 鲁志明  E-mail: 13688601037@139.com
 * @version 创建时间：2013-5-25 下午8:25:33 
 * 
 */
public class QQClient {

	public static void main(String[] args) {
		try {
			Socket client = new Socket("127.0.0.1",8000);
			new InputStreamThread(client).start();
			new OutputStreamThread(client).start();
		} catch (UnknownHostException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

InputStreamThread输入流线程

InputStreamThread.java

package com.net; 

import java.io.IOException;
import java.io.InputStream;
import java.net.Socket;

/** 
 * @author 鲁志明  E-mail: 13688601037@139.com
 * @version 创建时间：2013-5-25 下午8:26:05 
 * 
 */
public class InputStreamThread extends Thread{

	private Socket socket;
	
	public InputStreamThread(Socket socket) {
		this.socket = socket;
	}

	@Override
	public void run() {
		try {
			InputStream is = socket.getInputStream();
			byte[] message = new byte[1024];
			int messageLength = 0; 
			while(-1 != (messageLength = is.read(message, 0, message.length)))
			{
				System.out.println(new String(message,0,messageLength));
			}
			is.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

OutputStreamThread输出流线程

package com.net; 

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.Socket;

/** 
 * @author 鲁志明  E-mail: 13688601037@139.com
 * @version 创建时间：2013-5-25 下午8:26:42 
 * 
 */
public class OutputStreamThread extends Thread{

	private Socket socket;
	
	public OutputStreamThread(Socket socket) {
		this.socket = socket;
	}

	@Override
	public void run() {
		try {
			OutputStream os = socket.getOutputStream();
			InputStream is = System.in;
			byte[] message = new byte[1024];
			int messageLength = 0;
			while(-1 != (messageLength = is.read(message, 0, message.length)))
			{
				os.write(message, 0, messageLength);
			}
			os.close();
			is.close();
			
			
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

程序当中有什么写的不好的地方，忘大家指出。

共同进步！
