JAVA1.8 写一段二维码识别程序

这取决于你想要实现的功能，但基本上，你需要使用Java的类库来读取和解析图像数据，然后使用Zxing库来识别二维码。以下是一个示例代码： import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO; import com.google.zxing.BinaryBitmap;
import com.google.zxing.LuminanceSource;
import com.google.zxing.MultiFormatReader;
import com.google.zxing.Result;
import com.google.zxing.client.j2se.BufferedImageLuminanceSource;
import com.google.zxing.common.HybridBinarizer;public class QRCodeReader {
public static void main(String[] args) {
try {
File file = new File("myQRCode.png");
BufferedImage image = ImageIO.read(file);
LuminanceSource source = new BufferedImageLuminanceSource(image);
BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
Result result = new MultiFormatReader().decode(bitmap);
System.out.println("QRCode text is：" + result.getText());
} catch (Exception e) {
e.printStackTrace();
}
}
}
