利用zxing解析二维码

利用zxing解析生成的二维码的内容，源码如下：

package com.xz.erweima;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import java.util.HashMap;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 class ReadQRCode {public static void main(String[] args) {MultiFormatReader reader = new MultiFormatReader();try {//二维码的路径File file = new File("D:/img4.png");BufferedImage image = ImageIO.read(file);BinaryBitmap bitMap = new BinaryBitmap(new HybridBinarizer(new BufferedImageLuminanceSource(image)));//定义二维码所需要的参数 HashMap hints = new HashMap(); //定义编码 hints.put(EncodeHintType.CHARACTER_SET, "UTF-8"); Result result = reader.decode(bitMap,hints); System.out.println("解析结果："+result.toString()); System.out.println("二维码格式："+result.getBarcodeFormat()); System.out.println("文本内容为："+result.getText());} catch (NotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}
