java 实现截屏！
主要是利用java的几个先有的函数，如Robot这个类的一个方法createScreenCapture一个获得一个任意大小的屏幕图像（在这里是全屏图像），而所谓的截图就是在这个图像上画出一个矩形，再利用上面的方法获得这部分的图像，程序中的cf.setAlwaysOnTop(true)是必需的;看起来是在屏幕上截图，其实只是在一个在一个内镶有桌面背景的JFrame中截图。不知道还有没有其他的好方法~
附上代码：

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。
[java] view plaincopy
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, 0, 0, width, height, null);
//保存图片
ImageIO.write(bi, "jpg", new File("google.jpg"));
}
2、最常规的方式——利用JNI，调用第三方C/C++组件
方法详解：目前来讲，Java领域对于网页截图组件的开发明显不足（商机？），当您需要完成此种操作时，算得上碰到了Java的软肋。但是，众所周知Java也拥有强大的JNI能力，可以轻易将C/C++开发的同类组件引为己用。不懂可以扣五七八零二四一四四
优势：实现简单，只需要封装对应的DLL文件，就可以让Java实现同类功能。
劣势：同其他JNI实现一样，在跨平台时存在隐患，而且您的程序将不再属于纯Java应用。
java截屏有哪几种方法
前台方式
1. 利用html2canvas实现前台截屏
html2canvas项目的gitHub地址
html2canvas示例
html2canvas可以将HTML代码块进行截取，并生成快照形式的canvas，然后可以利用html5的下载功能提供图片的下载接口，供用户下载。
优点：前台技术，实现比较容易。
缺点：此项目使用了html5的技术，因此在对IE的兼容上，只可以在IE9+的版本上使用。
使用时，需要引用jQuery.js和html2canvas.js。（html2canvas.js可以在github上下载）
具体JavaScript代码如下:
var canvas = function () {
html2canvas($("#chart"), {
onrendered: function (canvas) {
$("#class11").html(canvas);//将id为“class11”部分的代码转换为canvas
var type = 'png';//图片类型为png
var imgData = canvas.toDataURL('png');//将图片转换为png类型的流
var _fixType = function (type) {
type = type.toLowerCase().replace(/jpg/i, 'jpeg'); var r = type.match(/png|jpeg|bmp|gif/)[0]; return 'image/' + r;
}; var saveFile = function (data, filename) {
var save_link = document.createElementNS('', 'a');
save_link.href = data;
save_link.download = filename; var event = document.createEvent('MouseEvents');
event.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
save_link.dispatchEvent(event);
}; //下载时的文件名
var filename = 'baidufe_' + (new Date()).getTime() + '.' + type; // 下载文件
saveFile(imgData, filename);
}
});
后台方式（java）
1. 利用html2image实现
html2image的地址（google）
html2image是可以识别html标签并将html转换成图片的java项目。
优点：后台转换，故对浏览器的版本基本没有要求。
缺点：对样式的识别不是很好，转换出来的图片比较简单，基本没有可以兼容的样式。
使用方式：maven中引用如下依赖：
dependency
groupIdcom.github.xuwei-k/groupId
artifactIdhtml2image/artifactId
version0.1.0/version/dependency12345
2. 利用DJNativeSwing项目实现
纯java代码实现。使用DJNativeSwing这个项目，构建一个swing浏览器，打开网址，之后截取图片。（需要eclipse的swt库支持）
优点：纯java实现。
缺点：需要多线程的支持，只在控制台方式实现过（由于本人对于多线程的掌握较弱，目前没有在spring项目中实现这个方法，求大神指导~~）
3. 利用phantomJs实现
phantomJs的GitHub地址
phantomJs官网
phantom利用的是webKit内核，全面支持web而不需浏览器支持，快速，原生支持各种Web标准。
优点：速度快，使用简单。
缺点：需要在项目的服务器端引用exe文件进行截图，并发性能有待考证。
