java 網絡編程（2.1）-----------多線程的Socket 通信

package leaningSocket; import java.io.*; import java.net.*; public class Test { private int port=8000; private ServerSocket serverSocket; public Test () throws IOException { serverSocket = new ServerSocket(port); System.out.println("服務器啓動"); } public void service() { while (true) { Socket socket=null; try { socket = serverSocket.accept(); //接收客戶連接 Thread workThread=new Thread(new Handler(socket)); //創建一個工作線程 workThread.start(); //啓動工作線程 }catch (IOException e) { e.printStackTrace(); } } } public static void main(String args[])throws IOException { new Test ().service(); } } /**繼承Runnable接口*/ class Handler implements Runnable{ private Socket socket; public Handler(Socket socket){ this.socket=socket; } private PrintWriter getWriter(Socket socket)throws IOException{ OutputStream socketOut = socket.getOutputStream(); return new PrintWriter(socketOut,true); } private BufferedReader getReader(Socket socket)throws IOException{ InputStream socketIn = socket.getInputStream(); return new BufferedReader(new InputStreamReader(socketIn)); } /**把客戶端發來的MSG 加上 “echo”後重新返回到客戶端*/ public String echo(String msg) { return "echo:" + msg; } public void run(){ try { /** * 每當有一個用戶鏈接到服務器時候就打印出下面這句話 * 當然也是每當有個用戶鏈接到服務器時就會創建一個線程 * 用戶多了就叫做多線程了^ ^ * */ System.out.println("New connection accepted " + socket.getInetAddress() + ":" +socket.getPort()); /**獲得輸入流裏的信息*/ BufferedReader br =getReader(socket); /**關聯到輸出流*/ PrintWriter pw = getWriter(socket); String msg = null; while ((msg = br.readLine()) != null) { /**把客戶端發送過來的信息打印出來*/ System.out.println(msg); /**網輸出流扔入信息，該信息將會顯示在客戶端*/ pw.println(echo(msg)); if (msg.equals("bye")) break; } }catch (IOException e) { e.printStackTrace(); }finally { try{ if(socket!=null)socket.close(); }catch (IOException e) {e.printStackTrace();} } } } /**************************************************** * 作者：孫衛琴 * * 來源：<<Java網絡編程精解>> * * 技術支持網址：www.javathinker.org * ***************************************************/   

 

 

看完了“單線程”然後就該看多線程了，發現多線程在理解上還是不難的，對於每個鏈接客戶端的用戶，我們都爲他

設置一個線程，然後在線程中進行事件處理。。。。嗯，暫時先這樣渾淪吞棗吧，繼續。。
