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();
		}
	}
}

快乐学习，快乐编程！
