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

package cn.huse.erweima;import java.io.File;import java.util.HashMap;import com.google.zxing.BarcodeFormat;import com.google.zxing.EncodeHintType;import com.google.zxing.MultiFormatWriter;import com.google.zxing.client.j2se.MatrixToImageWriter;import com.google.zxing.common.BitMatrix;import com.google.zxing.qrcode.decoder.ErrorCorrectionLevel;/** * 生成二维码 * */public class CreateQRCode { public static void main(String[] args) { int width = 300; int height = 300; String format = "gif"; String content = "mon.HybridBinarizer;//解析二维码public class ReadQRCode { public static void main(String[] args) { MultiFormatReader formatReader = new MultiFormatReader(); File file = new File("e:"+File.separator+"new.gif"); try { BufferedImage image = ImageIO.read(file); BinaryBitmap binaryBitmap = new BinaryBitmap(new HybridBinarizer(new BufferedImageLuminanceSource(image))); HashMap hints = new HashMap<>(); hints.put(EncodeHintType.CHARACTER_SET, "utf-8"); Result result = formatReader.decode(binaryBitmap,hints); System.out.println(result.toString()); System.out.println(result.getBarcodeFormat()); System.out.println(result.getText()); } catch (NotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }}
