java tcp连接服务端，每隔一秒发送一条消息，双击button开启，但是这时候界面就卡死了。怎么样才能不卡死

btnNewButton.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseDoubleClick(MouseEvent e) {

                String ip = "192.168.1.25"; // 服务器端ip地址

要是用多线程，你可以去网上找个tcp多线程客户端来，把你代码里面的socket改为开一个新的线程来完成

class ClientThread implements Runnable {
        private Socket client;

        public ClientThread(Socket client) {
            this.client = client;
        }

        @Override
        public void run() {
            try {
                                            outputStream = client.getOutputStream();
                                    } catch (IOException e1) {
                                            // TODO Auto-generated catch block
                                            e1.printStackTrace();
                                    }
                                    //InputStream inputStream = null;
                                    try {
                                            inputStream = client.getInputStream();
                                    } catch (IOException e1) {
                                            // TODO Auto-generated catch block
                                            e1.printStackTrace();
                                    }

                                    while (true) {
                                                    try {
                                                            outputStream.write(buff);
                                                            outputStream.flush();
                                                    } catch (IOException e1) {
                                                            // TODO Auto-generated catch block
                                                            e1.printStackTrace();
                                                    }

                                                    try {
                                                            Thread.sleep(1000);
                                                    } catch (InterruptedException e1) {
                                                            // TODO Auto-generated catch block
                                                            e1.printStackTrace();
                                                    }           

                                                    byte revBuff[] = new byte[1024];

                                                    try {
                                                            inputStream.read(revBuff);


                                                    } catch (IOException e1) {
                                                            // TODO Auto-generated catch block
                                                            e1.printStackTrace();
                                                    }
                                                    System.out.println(new String(revBuff));                
                                    }
            }
    }

btnNewButton.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseDoubleClick(MouseEvent e) {

                String ip = "192.168.1.25"; // 服务器端ip地址
                int port = 8899;
                //Socket socketSend = null;
                try {
                    socket = new Socket(ip, port);
                    //connectStatus = true;
                } catch (IOException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                }
                             new Thread(new ClientThread(socket)).start();
            }
}

电脑没Java 环境，没测试过，是在你代码基础上改了下
