现在做Java直接使用Socket的情况是越来越少,因为有很多的选择可选,比如说可以用spring,其中就可以支持很多种远程连接的操作,另外jboss的remoting也是不错的选择,还有Apache的Mina等等,但是在有些时候一些特殊情况仍然逃脱不了直接写Socket的情况,比如公司内部一些莫名其妙的游戏规则。
废话不说了,下面就看看如果自己写Socket应该怎么做吧。
首先是写一个Server类,这个类用来监听10000端口,并从这个端口接收消息然后输出,当收到“bye”时退出。
package com.googlecode.garbagecan.test.socket.sample1; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket; public class MyServer { public static void main(String[] args) throws IOException { ServerSocket server = new ServerSocket(10000); Socket socket = server.accept(); BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())); PrintWriter out = new PrintWriter(socket.getOutputStream()); while (true) { String msg = in.readLine(); System.out.println(msg); out.println("Server received " + msg); out.flush(); if (msg.equals("bye")) { break; } } socket.close(); } }
然后是一个Client类,这个类连接上面启动的Server类,然后接收任何用户输入,当遇到回车时发送字符串到Server上,当输入“bye”是退出。
package com.googlecode.garbagecan.test.socket.sample1; import java.io.BufferedReader; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.Socket; public class MyClient { public static void main(String[] args) throws Exception { Socket socket = new Socket("localhost", 10000); BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())); PrintWriter out = new PrintWriter(socket.getOutputStream()); BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); while (true) { String msg = reader.readLine(); out.println(msg); out.flush(); if (msg.equals("bye")) { break; } System.out.println(in.readLine()); } socket.close(); } }
最后,首先运行MyServer类,然后MyClient类,然后在MyClient的控制台输入任意字符,可以看到当输入bye是server和client都会退出。
