Java Socket编程在我们编程序的时候有很广泛的应用,在应用的时候我们就会遇到不少的障碍。下面我们就看看如何才能更好的进行相关问题的学习。希望大家看完下面的代码对Java Socket编程有所收获。
- package sterning;
- import java.io.BufferedReader;
- import java.io.IOException;
- import java.io.InputStream;
- import java.io.InputStreamReader;
- import java.io.OutputStream;
- import java.io.PrintWriter;
- import java.net.*;
- import java.util.concurrent.*;
- public class MultiThreadServer {
- private int port=8821;
- private ServerSocket serverSocket;
- private ExecutorService executorService;//线程池
- private final int POOL_SIZE=10;//单个CPU线程池大小
- public MultiThreadServer() throws IOException{
- serverSocket=new ServerSocket(port);
- //Runtime的availableProcessor()方法返回当前系统的CPU数目.
- executorService=Executors.newFixedThreadPool
(Runtime.getRuntime().availableProcessors()*POOL_SIZE);- System.out.println("服务器启动");
- }
- public void service(){
- while(true){
- Socket socket=null;
- try {
- //接收客户连接,只要客户进行了连接,就会触发accept();从而建立连接
- socket=serverSocket.accept();
- executorService.execute(new Handler(socket));
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
- }
- public static void main(String[] args) throws IOException {
- new MultiThreadServer().service();
- }
- }
- class Handler implements Runnable{
- private Socket socket;
- public Handler(Socket socket){
- this.socket=socket;
- }
- private PrintWriter getWriter(Socket socket) throws
IOException{- OutputStream socketsocketOut=socket.getOutputStream();
- return new PrintWriter(socketOut,true);
- }
- private BufferedReader getReader(Socket socket) throws
IOException{- InputStream socketsocketIn=socket.getInputStream();
- return new BufferedReader(new InputStreamReader
(socketIn));- }
- public String echo(String msg){
- return "echo:"+msg;
- }
- public void run(){
- try {
- System.out.println("New connection accepted "+
socket.getInetAddress()+":"+socket.getPort());- BufferedReader br=getReader(socket);
- PrintWriter pw=getWriter(socket);
- String msg=null;
- while((msg=br.readLine())!=null){
- System.out.println(msg);
- 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();
- }
- }
- }
- }
以上就是对Java Socket编程的相关代码介绍。
