java基於maven實現zxing產生二維碼__java

代碼如下：
1.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>

2.產生二維碼：

package com;import java.io.File;import java.io.IOException;import java.nio.file.Path;import java.util.Hashtable;import com.google.zxing.BarcodeFormat;import com.google.zxing.EncodeHintType;import com.google.zxing.MultiFormatWriter;import com.google.zxing.WriterException;import com.google.zxing.client.j2se.MatrixToImageWriter;import com.google.zxing.common.BitMatrix;import com.google.zxing.qrcode.decoder.ErrorCorrectionLevel;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();//在D盤產生二維碼圖片    MatrixToImageWriter.writeToPath(bitMatrix, format, file);    } catch (WriterException e) {    // TODO Auto-generated catch block    e.printStackTrace();}

3.解析二維碼：

package com;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import java.util.Hashtable;import javax.imageio.ImageIO;import com.google.zxing.BinaryBitmap;import com.google.zxing.EncodeHintType;import com.google.zxing.MultiFormatReader;import com.google.zxing.NotFoundException;import com.google.zxing.Result;import com.google.zxing.client.j2se.BufferedImageLuminanceSource;import com.google.zxing.common.HybridBinarizer;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("解析結果："+result.toString());    System.out.println(result.getBarcodeFormat());    System.out.println(result.getText());}
