非常简单的Socket聊天程序

新手一枚   不好别喷的太严重了

建立 服务端 ：

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
/**
 * 
 * @author bigSea
 *	Socket服务端
 */
public class MyTcpService {
	
	public static void main(String[] args) {
		System.out.println("主机启动。。。");
		try {
			//创建服务器,并开放10000端口
			ServerSocket server = new ServerSocket(10000);
			while(true){
				//从连接队列中取出一个连接，如果没有则等待
				Socket socket = server.accept();
				//启动线程
				new Thread(new ToClientDialog(socket)).start();
				System.out.println("客户端连接成功      地址："+socket.getInetAddress()+"   端口:"+socket.getPort());//接收和发送数据
				
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
           

ToClientDialog类：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.text.SimpleDateFormat;
import java.util.Date;
/**
 * 
 * @author bigSea
 *	向客户端发送数据
 */
public class ToClientDialog implements Runnable{

	private Socket dialogSocket = null;
	
	public ToClientDialog() {
		super();
	}
	
	//初始化
	public ToClientDialog(Socket socket){
		dialogSocket = socket;
	}
	
	public void run() {
		
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		
		if (dialogSocket != null) {
			BufferedReader in;
			PrintWriter out;
			try {
				//接收
				in = new BufferedReader(new InputStreamReader(dialogSocket.getInputStream()));
				//输出
				out = new PrintWriter(dialogSocket.getOutputStream(), true);
				//获取用户输入
				BufferedReader line = new BufferedReader(new InputStreamReader(
						System.in));
				while(true){
					//接收客户端发送来的数据
					String msg = in.readLine();
					if (msg.equals("end")) {
						break;
					}
					System.out.println(sdf.format(new Date()) + "  client：" + msg);
					//向客户端发送用户输入的数据
					out.println(line.readLine());
				}
				
				line.close();
				out.close();
				in.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}
	
}
           

客户端代码：

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

/**
 * @author bigSea
 *  Socket 服务端
 */
public class MyTcpClient {
	
	public static void main(String[] args) {
		System.out.println("客户机启动。。。");
		Socket socket;
		try {
			//连接主机地址。
			socket = new Socket("192.168.72.175", 10000);
			//启动
			new Thread(new ToServiceDialog(socket)).start();
			
		} catch (UnknownHostException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
           

ToServiceDialog代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * 
 * @author bigSea
 *  向服务端发送信息
 */
public class ToServiceDialog implements Runnable {

	private Socket dialogSocket = null;	
	
	public ToServiceDialog(){
	}
	
	//初始化
	public ToServiceDialog(Socket socket){
		dialogSocket = socket;
		System.out.println("连接"+socket.getInetAddress().getHostName()+"主机成功");
	}
	
	public void run() {
		BufferedReader in;
		PrintWriter out;
		BufferedReader line;

		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		if (dialogSocket != null) {
			try {
				//接收
				in = new BufferedReader(new InputStreamReader(
						dialogSocket.getInputStream()));
				//输出
				out = new PrintWriter(dialogSocket.getOutputStream(), true);
				//获取用户输入
				line = new BufferedReader(new InputStreamReader(
						System.in));
				while(true){
					//接受控制台输入的数据
					String sendMsg = line.readLine();
					//向服务端发送数据
					out.println(sendMsg);
					if (sendMsg.equals("end")) {
						break;
					}
					//接收服务端发送来的数据
					String msg = in.readLine();
					System.out.println(sdf.format(new Date()) + "  service：" + msg);
				}
				line.close();
				out.close();
				in.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}

}
