服务端多线程阻塞：

/***** *  * @author skiky * @describle *  */public class ClientSt {private final static Integer port = 10001;private PrintWriter out = null;private Socket socket = null;public void sendMessageToService(String message) {try {

InetAddress addr = InetAddress.getByName(null);  //为null 代表本机ipsocket = new Socket(addr, port);out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);for (;;) {Thread.sleep(1000);out.println(message);}} catch (IOException e) {e.printStackTrace();} catch (InterruptedException e) {e.printStackTrace();} finally {try {if (null != out) {out.close();}if (null != socket) {socket.close();}} catch (IOException e1) {e1.printStackTrace();}}}public static void main(String[] args) {new ClientSt().sendMessageToService("卡卡西，你好");}}
