jsp 截屏,保存为图片
你服务器的java代码不可能执行在客户端的电脑上的，所以这个只能通过js来做了，推荐使用jquery插件，推荐用jquery.Jcrop包你满意。
如何以JAVA实现网页截图技术
事实上，如果您想以Java实现网页截图，也就是“输入一段网址，几秒钟过后就能截取一张网页缩略图”的效果。那么，您至少有3种方式可以选择。
1、最直接的方式——使用Robot
方法详解：该方法利用Robat提供的强大桌面操作能力，硬性调用浏览器打开指定网页，并将网页信息保存到本地。
优势：简单易用，不需要任何第三方插件。
缺点：不能同时处理大量数据，技术含量过低，属于应急型技巧。
实现方法：使用如下代码即可。
public static void main(String[] args) throws MalformedURLException,
IOException, URISyntaxException, AWTException {
//此方法仅适用于JdK1.6及以上版本
Desktop.getDesktop().browse(
new URL(“”).toURI());
Robot robot = new Robot();
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

java 中的Robot类的createScreenCapture方法能不能截取包含鼠标的桌面
它截取的只是一个静态的图片,当然无法动态地显示光标变化,但是可以控制它在每秒内截取多少次,每截取一次进行一次发送,再在客户端动态地显示出来就行了.
我前段时间也在做这样的一个东西,可以共同学习啊.
