java socket保持长连接

ServerSocket serverSocket=new ServerSocket(1111);Socket socket=serverSocket.accept();while(true){//保持长连接   try {       Thread.sleep(100);//等待时间   } catch (InterruptedException e1) {       e1.printStackTrace();   }if (socket !=null){   try {      String ip = socket.getInetAddress().toString().replace("/", "");         System.out.println("====socket.getInetAddress()====="+ip);          socket.setKeepAlive(true);          InputStream is = socket.getInputStream();          OutputStream os = socket.getOutputStream();          System.out.println("服务器端接受请求");String tempdata = StreamEazyUse.getContent(is);system.out.printl(“接收到的数据为：”+tempdata);if(tempdata.contains(“stop”)){is.close();os.close();}os.flush();}catch(Exception e){system.out.println(“出现了错误”);}}}
