java Socket(二)

上次做了一个java socket一对一通信的例子这次来写一个一对多的通信,这里我们使用java的多线程来实现

首先来看一下服务类

[java]

/**?

?*??

?*/??

package?com.dnion.socket;??

import?java.io.IOException;??

import?java.net.ServerSocket;??

import?java.net.Socket;??

/**?

?***************************************************************??

?*?项目名称：JavaThread?

?*?程序名称：MultiJabberServer?

?***************************************************************?

?*/??

public?class?MultiJabberServer?{??

??????

????/**?

?????*?方法名：main?

?????*?描述：?

?????*?作者：?

?????*?日期：2012-8-23?下午02:38:20?

?????*?@param?@param?args?

?????*?@return?void?

?????*/??

????public?static?void?main(String[]?args)?{??

????????ServerSocket?s?=?null;??

????????Socket?socket??=?null;??

????????try?{??

????????????s?=?new?ServerSocket(8080);??

????????????//等待新请求、否则一直阻塞??

????????????while(true){??

????????????????socket?=?s.accept();??

????????????????System.out.println("socket:"+socket);??

????????????????new?ServeOneJabbr(socket);??

??????????????????

????????????}??

????????}?catch?(Exception?e)?{??

????????????try?{??

????????????????socket.close();??

????????????}?catch?(IOException?e1)?{??

????????????????//?TODO?Auto-generated?catch?block??

????????????????e1.printStackTrace();??

????????????}??

????????}finally{??

????????????try?{??

????????????????s.close();??

????????????}?catch?(IOException?e)?{??

????????????????//?TODO?Auto-generated?catch?block??

????????????????e.printStackTrace();??

????????????}??

????????}??

??????????

????}??

}??

接着我们要写一个服务端响应请求的类也就是一个socket

[java]

/**?

?*??

?*/??

package?com.dnion.socket;??

import?java.io.BufferedReader;??

import?java.io.BufferedWriter;??

import?java.io.IOException;??

import?java.io.InputStreamReader;??

import?java.io.OutputStreamWriter;??

import?java.io.PrintWriter;??

import?java.net.Socket;??

/**?

?***************************************************************??

?*?项目名称：JavaThread?

?*?程序名称：ServeOneJabbr?

?*?日期：2012-8-23?下午02:34:13?

?*??

?*?修改备注：?

?*?@version??

?***************************************************************?

?*/??

public?class?ServeOneJabbr?extends?Thread{??

????private?Socket?socket?=?null;??

????private?BufferedReader?br?=?null;??

????private?PrintWriter?pw?=?null;??

??????

????public?ServeOneJabbr(Socket?s){??

????????socket?=?s;??

????????try?{??

????????????br?=?new?BufferedReader(new?InputStreamReader(socket.getInputStream()));??

????????????pw?=?new?PrintWriter(new?BufferedWriter(new?OutputStreamWriter(socket.getOutputStream())),true);??

????????????start();??

????????}?catch?(Exception?e)?{??

??????????????

????????????e.printStackTrace();??

????????}??

????}??

??????

????@Override??

????public?void?run()?{??

????????while(true){??

????????????String?str;??

????????????try?{??

????????????????str?=?br.readLine();??

????????????????if(str.equals("END")){??

????????????????????br.close();??

????????????????????pw.close();??

????????????????????socket.close();??

????????????????????break;??

????????????????}??

????????????????System.out.println("Client?Socket?Message:"+str);??

????????????????pw.println("Message?Received");??

????????????????pw.flush();??

????????????}?catch?(Exception?e)?{??

????????????????try?{??

????????????????????br.close();??

????????????????????pw.close();??

????????????????????socket.close();??

????????????????}?catch?(IOException?e1)?{??

????????????????????//?TODO?Auto-generated?catch?block??

????????????????????e1.printStackTrace();??

????????????????}??

????????????}??

????????}??

????}??

??????

}??

接下来利用我们上一次的客户端socket

这样一个简单地多客户端响应socket就成了

每次有一个请求发送过来服务端都会新建一个线程来单独服务。
