			BinaryBitmap binaryBitmap = new BinaryBitmap(new HybridBinarizer(new BufferedImageLuminanceSource(image)));
			
			//定义二维码参数
			HashMap hints = new HashMap();
			hints.put(EncodeHintType.CHARACTER_SET, "UTF-8");
			Result result =  formatReader.decode(binaryBitmap,hints);
			
			System.out.println("解析结果"+result.toString());
