Map<DecodeHintType, String> m = new HashMap<>();//二維碼或條形碼的引數
m.put(DecodeHintType.CHARACTER_SET, "utf-8");//設定編碼
Result s = new MultiFormatReader().decode(new BinaryBitmap(new HybridBinarizer(new BufferedImageLuminanceSource((BufferedImage) i))), m);//二維碼或條形碼
System.out.println(s.getText());//輸出二維碼或條形碼的內容
System.out.println(s.getBarcodeFormat());//輸出掃描到得是二維碼還是條形碼
}
}結果
控制臺輸出:
二維碼或條形碼(D:\1.png)的內容
掃描到的是二維碼還是條形碼
