Java下的一个socket服务器，用于自我测试

import java.io.*;import java.net.*;public class socket extends ServerSocket {private static final int SERVER_PORT = 9000;public socket() throws IOException {super(SERVER_PORT);try {while (true) {Socket socket = accept();new CreateServerThread(socket);}} catch (IOException e) {} finally {close();}}// --- CreateServerThreadclass CreateServerThread extends Thread {private Socket client;private BufferedReader in;private PrintWriter out;public CreateServerThread(Socket s) throws IOException {client = s;System.out.println("Connect:" + client.toString());in = new BufferedReader(new InputStreamReader(client.getInputStream(), "GB2312"));out = new PrintWriter(client.getOutputStream(), true);out.println("--- Welcome ---");start();}public void run() {try {String line = in.readLine();System.out.println("[" + getId() + "]send:[" + line + "]");while (!line.equals("bye")) {String msg = createMessage(line);out.println(msg);line = in.readLine();System.out.println("[" + getId() + "]send:[" + line + "]");}System.out.println("[" + getId() + "]bye");out.println("--- Bye! ---");in.close();out.close();client.close();} catch (IOException e) {}}private String createMessage(String line) {return "You say:[" + line + "]";}}public static void main(String[] args) throws IOException {new socket();}}

对每个客户端连接建立一个新线程，与客户端以一次一行方式进行对话，以客户端发送bye作为结束
