Spring Boot整合ZXing实现二维码和条形码生成

        String barcodeContent = "这是条形码包含的信息";
 
        try {
            generateQRCodeImage(qrContent, "qrcode.png");
            generateBarcodeImage(barcodeContent, "barcode.png");
        } catch (WriterException | IOException e) {
            e.printStackTrace();
        }
    }
 
    private static void generateQRCodeImage(String content, String imagePath) throws WriterException, IOException {
        QRCodeWriter qrCodeWriter = new QRCodeWriter();
        BitMatrix bitMatrix = qrCodeWriter.encode(content, BarcodeFormat.QR_CODE, 500, 500);
        Path path = FileSystems.getDefault().getPath(imagePath);
        MatrixToImageWriter.writeToPath(bitMatrix, "PNG", path);
    }
 
    private static void generateBarcodeImage(String content, String imagePath) throws IOException, WriterException {
        Code128Writer code128Writer = new Code128Writer();
        BitMatrix bitMatrix = code128Writer.encode(content, BarcodeFormat.CODE_128, 500, 100);
        Path path = FileSystems.getDefault().getPath(imagePath);
        MatrixToImageWriter.writeToPath(bitMatrix, "PNG", path);
    }
}

这段代码使用了ZXing库来生成二维码和条形码，并将生成的图像保存到指定的文件路径。在这个例子中，我们创建了两个方法generateQRCodeImage和generateBarcodeImage，分别用于生成二维码和条形码图像，并在main方法中调用这两个方法进行测试。
