如何在服务器上同时阅读和写作 [英] How Can I Reading And Writing At The Same Time On Server

问题描述

我在java中编写一个服务器，用于发送手机图像并同时从中读取数据，手机发送触摸位置以及如果手机上没有触摸就会卡住读取的问题，这是非常慢地

i write a server in java that sending images for phone and reading data from it at the same time, the phone sending the position of touch and the problem that stuck on read if there is no touch on the phone, and it's been very slowlly

private void whileConnecting() throws IOException, AWTException {  
    byte[] buffer;
    while(connection.isConnected()){

        x = input.readFloat();
        y = input.readFloat();
        System.out.println("x = y");

    capture = robot.createScreenCapture(screenRectangle);//capture whole screen 
    baos = new ByteArrayOutputStream();//this object will receive the capture image
    ImageIO.write(capture, "jpg", baos);//chose "JPG" because this is the best image's format from size and quality 
    baos.flush();//flush all the bytes 
    System.out.println("Size of baos = " + baos.size());
    buffer = baos.toByteArray();//convert ByteArrayOutputStream to bytes array that can to send it over socket
    baos.close();//close the ByteArrayOutputStream to can write in it again, if not closed it will append images
    output.writeObject(buffer);//send the image's byte array over the socket
    output.flush();//flush all bytes 
    }
}   

推荐答案

我会创建两个具有不同端口号的套接字，一个用于用于接收数据的图像和其他图像。

I would create two sockets with different port numbers, one for the images and other for receiving the data.
