CapturerHelper.class

 public static void main(String[] args)
    throws Exception
  {
    String userDir = System.getProperty("user.home");

    File tempFile = new File(userDir + "\\桌面\\" + DateHelper.format("dd-HH-mm-ss") + ".jpg");

    CapturerHelper capturer = getInstance();

    capturer.captureImage();

    capturer.saveAsJPEG(tempFile);

    ClipboardHelper.setImage(capturer.getPickedImage());

    System.exit(0);
  }

可能你的桌面的名字不是"桌面".你可以编译下CapturerHelper这个类,来指定其它目录.

怎么指定保存路径,默认放在桌面上报了FileNotFoundException
