Java Socket编程关键代码详解

Java Socket编程如何才能更好的进行相关代码的学习，当然我们只有不断的研究才能更好的使用。下面我们就详细的学习下。

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JavaSocket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。
