解析二维码：
public static void main(String[] args) throws NotFoundException {
MultiFormatReader formatReader=new MultiFormatReader();
File file =new File("D:/new.png");
BufferedImage image=null;
try {
image = ImageIO.read(file);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
BinaryBitmap binaryBitmap =new BinaryBitmap(new HybridBinarizer(new BufferedImageLuminanceSource(image)));
Hashtable hints=new Hashtable();
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());
}
