Java中基于maven实现zxing二维码功能
作者:攻城师_翔
这篇文章主要介绍了Java中基于maven实现zxing二维码功能,非常不错,具有参考借鉴价值,需要的朋友可以参考下
maven所需jar
<dependency> <groupId>com.google.zxing</groupId> <artifactId>core</artifactId> <version>3.0.0</version> </dependency> <dependency> <groupId>com.google.zxing</groupId> <artifactId>javase</artifactId> <version>3.0.0</version> </dependency>
生成二维码:
public static void main(String[] args) throws IOException { String text="www.baidu.com"; int width=100; int height=100; String format="png"; Hashtable hints=new Hashtable(); hints.put(EncodeHintType.CHARACTER_SET, "utf-8"); hints.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.M); hints.put(EncodeHintType.MARGIN, 2); try { BitMatrix bitMatrix=new MultiFormatWriter().encode(text, BarcodeFormat.QR_CODE, width, height,hints); Path file=new Java.io.File("D:/new.png").toPath(); MatrixToImageWriter.writeToPath(bitMatrix, format, file); } catch (WriterException e) { // TODO Auto-generated catch block e.printStackTrace(); } 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()); }
