java多线程控制台聊天室(转)

用java多线程实现一个控制台聊天室，呵呵，好玩！
聊天室服务器端

package tf.thread;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
public class ChatServer {
private static final int PORT = 8888; // 端口号
private static List<Socket> list = new ArrayList<Socket>(); // 保存连接对象
private ExecutorService exec;
private ServerSocket server;
public static void main(String[] args) {
new ChatServer();
}
public ChatServer() {
try {
server = new ServerSocket(PORT);
exec = Executors.newCachedThreadPool();
System.out.println("服务器已启动！");
Socket client = null;
while (true) {
client = server.accept(); // 接收客户连接
list.add(client);
exec.execute(new ChatTask(client));
}
} catch (IOException e) {
e.printStackTrace();
}
}
static class ChatTask implements Runnable {
private Socket socket;
private BufferedReader br;
private PrintWriter pw;
private String msg;
public ChatTask(Socket socket) throws IOException {
this.socket = socket;
br = new BufferedReader(new InputStreamReader(socket
.getInputStream()));
msg = "【" + this.socket.getInetAddress() + "】进入聊天室！当前聊天室有【"
+ list.size() + "】人";
sendMessage();
}
public void run() {
try {
while ((msg = br.readLine()) != null) {
if (msg.trim().equals("bye")) {
list.remove(socket);
br.close();
pw.close();
msg = "【" + socket.getInetAddress() + "】离开聊天室！当前聊天室有【"
+ list.size() + "】人";
socket.close();
sendMessage();
break;
} else {
msg = "【" + socket.getInetAddress() + "】说：" + msg;
sendMessage();
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
/**
* 群发消息给聊天室的所有人
*/
private void sendMessage() throws IOException {
System.out.println(msg);
for (Socket client : list) {
pw = new PrintWriter(client.getOutputStream(), true);
pw.println(msg);
}
}
}
}

聊天室客户端（输入bye可退出聊天室）

package tf.thread;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
public class ChatClient {
private static final int PORT = 8888;
private static ExecutorService exec = Executors.newCachedThreadPool();
public static void main(String[] args) throws Exception {
new ChatClient();
}
public ChatClient() {
try {
Socket socket = new Socket("192.168.1.120", PORT);
exec.execute(new Sender(socket));
System.out
.println("【" + socket.getInetAddress() + "】您好，欢迎来到阿飞聊天室！");
BufferedReader br = new BufferedReader(new InputStreamReader(socket
.getInputStream()));
String msg;
while ((msg = br.readLine()) != null) {
System.out.println(msg);
}
} catch (Exception e) {
}
}
/**
* 客户端线程获取控制台输入消息
*/
static class Sender implements Runnable {
private Socket socket;
public Sender(Socket socket) {
this.socket = socket;
}
public void run() {
try {
BufferedReader br = new BufferedReader(new InputStreamReader(
System.in));
PrintWriter pw = new PrintWriter(socket.getOutputStream(), true);
String msg;
while (true) {
msg = br.readLine();
pw.println(msg);
if (msg.trim().equals("bye")) {
pw.close();
br.close();
exec.shutdownNow();
break;
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
