如何以Java实现网页截图技术，根据URL得到网页快照

// 此方法仅适用于JdK1.6及以上版本
Desktop.getDesktop().browse(
new URL("http://www.csdn.net/").toURI());
Robot robot = new Robot();
//停留10s
//robot.delay(10000);
Dimension d = new Dimension(Toolkit.getDefaultToolkit().getScreenSize());
int width = (int) d.getWidth();
int height = (int) d.getHeight();
// 最大化浏览器
robot.keyRelease(KeyEvent.VK_F11);
robot.delay(2000);
Image image = robot.createScreenCapture(new Rectangle(0, 0, width,
height));
BufferedImage bi = new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB);
Graphics g = bi.createGraphics();
g.drawImage(image, 0, 0, width, height, null);
// 保存图片
ImageIO.write(bi, "jpg", new File("c:/iteye.com.jpg"));
