java學習筆記——基於Robot類的屏幕分享

　　直接上代碼，具體看注釋：

package robot;

import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.FileNotFoundException;
import java.util.concurrent.TimeUnit;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class TestRotbot {

	public static void main(String[] args) throws FileNotFoundException {
		Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
		JFrame showImage = new JFrame("屏幕共享");
		showImage.setBounds(0, 0, 300, 300);
		JLabel imageLabel = new JLabel();  //用於接收屏幕
		showImage.setVisible(true);
		showImage.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		int height = (int)screenSize.getHeight();
		int width = (int)screenSize.getWidth();
		try {
			Robot robot = new Robot();
			imageLabel.setBounds(0, 0, showImage.getWidth(), showImage.getHeight());
			Rectangle screenRect = new Rectangle(0, 0, width, height);
			while(true){
				BufferedImage imageW = robot.createScreenCapture(screenRect);			
				showImage.add(imageLabel);
				imageLabel.setIcon(new ImageIcon(imageW));  //獲取屏幕內容								
				TimeUnit.MILLISECONDS.sleep(50);
				
				imageW.flush();
			}
			
		} catch (AWTException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

}

　　  本文代碼只做原理演示，具體的屏幕分享仍需進一步的完善，需要客戶端和服務器端共同完成。
