java二维码--QRCode解析问题

	public static void main(String[] args) {
		File file = new File("G:/imooc/code/qrCodeImg.png");
		try {
			BufferedImage bi = ImageIO.read(file);
			
			QRCodeDecoder decoder = new QRCodeDecoder();
			
			System.out.println("开始解析...");
			byte[] data = decoder.decode(new MyQRCodeImage(bi));
			
			String result = new String(data , "UTF-8");
			
			System.out.println("解析出来的数据为:" + result);
			
		} catch (DecodingFailedException dfe) {  
            System.out.println("Error: " + dfe.getMessage()); 
            dfe.printStackTrace();
        } catch (UnsupportedEncodingException e) {  
            e.printStackTrace();  
        } catch (IOException e) {
			e.printStackTrace();
		}  
		
	}

在做QRCode测试解析二维码的时候报了这个错误

Error: Give up decoding
jp.sourceforge.qrcode.exception.DecodingFailedException: Give up decoding
	at jp.sourceforge.qrcode.QRCodeDecoder.decode(QRCodeDecoder.java:88)
	at cn.zhang.qrcode.ReadQRCode_test.main(ReadQRCode_test.java:29)

在网上查了很多资料，没有找到解决办法
