　　测试2：生成图片

public static void main(String[] args) {String data = "Marydon";// 不带logoBufferedImage image = createQRCode(data);String fileName = "博客园";File qrcodeFile = new File("d:/" + fileName + ".png");ZxingQrcode.writeToFile(image, qrcodeFile);// 带logoFile logoFile = new File("D:\\ewm.jpg");image = createQRCodeWithLogo(data, logoFile);fileName = "博客园2";qrcodeFile = new File("d:/" + fileName + ".png");ZxingQrcode.writeToFile(image, qrcodeFile);}

　　说明：生成的二维码图片如果它的上级目录不存在，会创建失败！

qrcodeFile = new File("d:/测试/" + fileName + ".png");
// 文件夹不存在，自动创建文件夹
if (!qrcodeFile.exists()) {qrcodeFile.mkdirs();
}
