解析二维码：

publicstaticvoidmain(String[] args)throwsNotFoundException {

MultiFormatReader formatReader=newMultiFormatReader();

File file =newFile("D:/new.png");

BufferedImage image=null;

try{

image = ImageIO.read(file);

}catch(IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

BinaryBitmap binaryBitmap =newBinaryBitmap(newHybridBinarizer(newBufferedImageLuminanceSource(image)));

Hashtable hints=newHashtable();

hints.put(EncodeHintType.CHARACTER_SET,"utf-8");

Result result=formatReader.decode(binaryBitmap,hints);

System.err.println("解析结果："+result.toString());

System.out.println(result.getBarcodeFormat());

System.out.println(result.getText());

}
