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());

									}
