JAVA实现的一个简单的Socket Server范例

随手做的一个简单的Socket服务器，用来模拟全向移动平台机上控制器的响应的，配合全向移动平台手机控制器调试用的。

在主线程里死循环监听端口12000，有客户端连接就新建一个子线程，在子线程里接受客户端数据（byte[10]，每个字节分别定义了运动状态、运动速度等信息），进行解析，在控制台显示当前速度或状态，回传数据。客户端退出则关闭子线程，返回主线程继续等待连接。

命令行运行 java -jar 程序名.jar

主线程代码：

public SocketServerForMecanum() {try {serverSocket = new ServerSocket(12000);} catch (IOException e) {//e.printStackTrace();System.out.println("Create ServerSocket Error...");}}@Overridepublic void run() {while (true) {System.out.println("Listenning...");try {// 每个请求交给一个线程去处理socket = serverSocket.accept();ServerThread serverThread = new ServerThread(socket);serverThread.start();sleep(1000);} catch (Exception e) {//e.printStackTrace();System.out.println("Create Socket Error...");}}}

子线程代码：

class ServerThread extends Thread {private Socket socket;private InputStream ins;private OutputStream ous;private byte[] buffer_received = new byte[10];private short moveX = 0, moveY = 0, rotate = 0;private int recount = 0;public ServerThread(Socket socket) {// super();this.socket = socket;try {ins = socket.getInputStream();ous = socket.getOutputStream();} catch (IOException e) {//e.printStackTrace();System.out.println("Create ServerThread Error...");}}@Overridepublic void run() {while (true) {try {ins.read(buffer_received);if (recount >= 5) {recount = 0;moveX = 0;moveX = (short) (buffer_received[5] & 0x00ff);moveX <<= 8;moveX |= (buffer_received[4] & 0x00ff);moveY = 0;moveY = (short) (buffer_received[7] & 0x00ff);moveY <<= 8;moveY |= (buffer_received[6] & 0x00ff);rotate = 0;rotate = (short) (buffer_received[9] & 0x00ff);rotate <<= 8;rotate |= (buffer_received[8] & 0x00ff);System.out.println("moveX=" + moveX + ";" + "moveY="+ moveY + ";" + "rotate=" + rotate + ";");} else {recount++;}/*//buffer的头字节为2，则认为收到了客户端主动请求关闭连接if (buffer_received[0] == 2) {ins.close();ous.close();socket.close();return;}*///模拟上电if (buffer_received[2] == 1) {System.out.println("Power ON...");}//模拟下电if (buffer_received[2] == 2) {System.out.println("Power OFF...");}//模拟停止if (buffer_received[2] == 4) {System.out.println("Stop Button Pushed!...");}//将首字节置1然后回传buffer_received[0] = 1;ous.write(buffer_received);} catch (IOException e) {//e.printStackTrace();System.out.println("Client Disconnected...");//当客户端因各种原因关闭连接而且没有通知服务端的，包括屏幕翻转、打开首选项等情况try {ins.close();ous.close();socket.close();} catch (IOException e1) {e1.printStackTrace();}return;}}}}
