原理就是截屏后获取到鼠标的位置，用java.awt.Graphics2D的.drawImage方法绘制鼠标即可，代码如下：

public class ScreenSnapshot {

    public static void main(String[] args) {

        try {
            Robot robot = new Robot();
            Toolkit toolkit= Toolkit.getDefaultToolkit();
            Rectangle screen_area= new Rectangle(toolkit.getScreenSize());

            Point p= MouseInfo.getPointerInfo().getLocation();
            BufferedImage screenshot= robot.createScreenCapture(screen_area);

            String imagepath = ScreenSnapshot.class.getResource("/").getPath().toString();

            BufferedImage cursor= ImageIO.read(new File(imagepath+"cursor.gif"));//cursor.gif 是你的鼠标图片
            screenshot.createGraphics().drawImage(cursor, p.x, p.y, null);

            ImageIO.write(screenshot, "jpg", new File("c:/cross/output.jpg"));
            ImageIO.write(screenshot, "png", new File("c:/cross/output.png"));
        } catch (HeadlessException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (AWTException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
}
