在http://code.google.com/p/zxing/downloads/list下载zxing压缩包(我用的Zxing-1.5),解压后将core/src和javase/src中的com文件夹整体复制到你的java工程中,这两个包里面包含java所用的java源码,
代码如下:
package com.easyoa.test;
import java.awt.image.BufferedImage;
importjava.io.File;
importjava.io.IOException;
import java.util.Hashtable;import javax.imageio.ImageIO;
import com.google.zxing.BarcodeFormat;
importcom.google.zxing.BinaryBitmap;
importcom.google.zxing.DecodeHintType;
importcom.google.zxing.LuminanceSource;
importcom.google.zxing.MultiFormatReader;
importcom.google.zxing.MultiFormatWriter;
importcom.google.zxing.Reader;
importcom.google.zxing.ReaderException;
importcom.google.zxing.Result;
importcom.google.zxing.client.j2se.BufferedImageLuminanceSource;
importcom.google.zxing.common.ByteMatrix;
import com.google.zxing.common.HybridBinarizer;public class Test {
privatestaticfinalintBLACK=0xff000000;
privatestaticfinalintWHITE=0xFFFFFFFF;
/**
*@paramargs
*/
publicstaticvoidmain(String[]args){
Testtest=newTest();
test.encode();
test.decode();
}
//编码
/**
*在编码时需要将com.google.zxing.qrcode.encoder.Encoder.java中的
*staticfinalStringDEFAULT_BYTE_MODE_ENCODING="ISO8859-1";修改为UTF-8,否则中文编译后解析不了
*/
publicvoidencode(){
try{
Stringstr="姓名:张三,性别:男,年龄:25,籍贯:中国北京,";//二维码内容
Stringpath="D://test.png";
ByteMatrixbyteMatrix;
byteMatrix=newMultiFormatWriter().encode(str,BarcodeFormat.QR_CODE,200,200);
Filefile=newFile(path);
writeToFile(byteMatrix,"png",file);
}catch(Exceptione){
e.printStackTrace();
}
}
publicstaticvoidwriteToFile(ByteMatrixmatrix,Stringformat,Filefile)
throwsIOException{
BufferedImageimage=toBufferedImage(matrix);
ImageIO.write(image,format,file);
}
publicstaticBufferedImagetoBufferedImage(ByteMatrixmatrix){
intwidth=matrix.getWidth();
intheight=matrix.getHeight();
BufferedImageimage=newBufferedImage(width,height,BufferedImage.TYPE_INT_ARGB);
for(intx=0;x<width;x++){
for(inty=0;y<height;y++){
image.setRGB(x,y,matrix.get(x,y)==0?BLACK:WHITE);
}
}
returnimage;
}
//解码
publicvoiddecode(){
try{
Readerreader=newMultiFormatReader();
StringimgPath="D://test.png";
Filefile=newFile(imgPath);
BufferedImageimage;
try{
image=ImageIO.read(file);
if(image==null){
System.out.println("Couldnotdecodeimage");
}
LuminanceSourcesource=newBufferedImageLuminanceSource(image);
BinaryBitmapbitmap=newBinaryBitmap(newHybridBinarizer(source));
Resultresult;
Hashtablehints=newHashtable();
hints.put(DecodeHintType.CHARACTER_SET,"utf-8");
//解码设置编码方式为:utf-8,
result=newMultiFormatReader().decode(bitmap,hints);
StringresultStr=result.getText();
System.out.println("解析后内容:"+resultStr);} catch (IOException ioe) {
System.out.println(ioe.toString());
}catch(ReaderExceptionre){
System.out.println(re.toString());
}}catch(Exception ex){
System.out.println(ex.toString());
}
}}
好了,运行一下是不是很简单?

解码后:
