谷歌生成二维码报异常Exception in thread "main" javax.imageio.IIOException: Can't create an ImageInputStream!

问题遇到的现象和发生背景

public static void main(String[] args) throws Exception {
String text = "第一个二维码";

    //嵌入二维码的图片路径
    //此路径为二维码中间的小图片 如果为null则生成一个纯净的二维码
    String imgPath = "E:\\qrCode\\image";
    //生成二维码的路径及名称
    String destPath = "E:\\qrCode";

// File file = new File("E:\毕业设计\hospital\src\main\resources\temp");
// ImageIO.setCacheDirectory(file);
// ImageIO.setUseCache(false);
QRCodeUtil.encode(text,imgPath,destPath,true);
String decode = QRCodeUtil.decode(destPath);
System.out.println(decode);
