今天寫了個socket的測試小程序，代碼如下

import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.net.Socket; import java.net.UnknownHostException;/** * @author 某家: * @version 創建時間：2015年8月17日 下午3:04:14 * 類說明 */ public class Connect {private static final ThreadLocal<Socket> threadConnect = new ThreadLocal<Socket>(); private static final String HOST = "192.168.1.120";private static final int PORT = 8888;private static Socket client;private static OutputStream outStr = null;private static InputStream inStr = null;private static Thread tRecv = new Thread(new RecvThread());private static Thread tKeep = new Thread(new KeepThread());public static void connect() throws UnknownHostException, IOException {client = threadConnect.get();if(client == null){client = new Socket(HOST, PORT);threadConnect.set(client);tKeep.start();System.out.println("========鏈接開始！========");}outStr = client.getOutputStream();inStr = client.getInputStream();}public static void disconnect() {try {outStr.close();inStr.close();client.close();} catch (IOException e) {e.printStackTrace();}}private static class KeepThread implements Runnable {public void run() {try {System.out.println("=====================開始發送心跳包==============");while (true) {try {Thread.sleep(1000);} catch (InterruptedException e) {// TODO Auto-generated catch block e.printStackTrace();}System.out.println("發送心跳數據包");outStr.write("send heart beat data package !".getBytes());}} catch (IOException e) {e.printStackTrace();}}}private static class RecvThread implements Runnable {public void run() {try {System.out.println("==============開始接收數據===============");while (true) {byte[] b = new byte[1024];int r = inStr.read(b);if(r>-1){String str = new String(b);System.out.println( str );}}} catch (IOException e) {e.printStackTrace();}}}public static void main(String[] args) {try {Connect.connect();tRecv.start();} catch (UnknownHostException e) {// TODO Auto-generated catch block e.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch block e.printStackTrace();}} }
