java二维码生成的方法
本文实例为大家分享了java二维码的实现代码，供大家参考，具体内容如下
这次用到的jar包是zxing，没有用到core的jar包
先导入zxing.jar包
生成二维码
packagecn.huse.erweima;
importjava.io.File;
importjava.util.HashMap;
importcom.google.zxing.BarcodeFormat;
importcom.google.zxing.EncodeHintType;
importcom.google.zxing.MultiFormatWriter;
importcom.google.zxing.client.j2se.MatrixToImageWriter;
importcom.google.zxing.common.BitMatrix;
importcom.google.zxing.qrcode.decoder.ErrorCorrectionLevel;
/**
*生成二维码
*
*/
publicclassCreateQRCode{
publicstaticvoidmain(String[]args){
intwidth=300;
intheight=300;
Stringformat="gif";
Stringcontent="www.baidu.com";
//定义二维码的参数
HashMaphints=newHashMap<>();
hints.put(EncodeHintType.CHARACTER_SET,"utf-8");
hints.put(EncodeHintType.ERROR_CORRECTION,ErrorCorrectionLevel.M);
try{
BitMatrixmatrix=newMultiFormatWriter().encode(content,BarcodeFormat.QR_CODE,width,height,hints);
Filefile=newFile("e:"+File.separator+"new.gif");
MatrixToImageWriter.writeToFile(matrix,format,file);
}catch(Exceptione){
e.printStackTrace();
}
}
}
解析二维码
packagecn.huse.erweima;
importjava.awt.image.BufferedImage;
importjava.io.File;
importjava.io.IOException;
importjava.util.HashMap;
importjavax.imageio.ImageIO;
importcom.google.zxing.BinaryBitmap;
importcom.google.zxing.EncodeHintType;
importcom.google.zxing.MultiFormatReader;
importcom.google.zxing.NotFoundException;
importcom.google.zxing.Result;
importcom.google.zxing.client.j2se.BufferedImageLuminanceSource;
importcom.google.zxing.common.HybridBinarizer;
//解析二维码
publicclassReadQRCode{
publicstaticvoidmain(String[]args){
MultiFormatReaderformatReader=newMultiFormatReader();
Filefile=newFile("e:"+File.separator+"new.gif");
try{
BufferedImageimage=ImageIO.read(file);
BinaryBitmapbinaryBitmap=newBinaryBitmap(newHybridBinarizer(newBufferedImageLuminanceSource(image)));
HashMaphints=newHashMap<>();
hints.put(EncodeHintType.CHARACTER_SET,"utf-8");
Resultresult=formatReader.decode(binaryBitmap,hints);
System.out.println(result.toString());
System.out.println(result.getBarcodeFormat());
System.out.println(result.getText());
}catch(NotFoundExceptione){
e.printStackTrace();
}catch(IOExceptione){
e.printStackTrace();
}
}
}
