如何将长字符串分成多个qr区域？

Question

使用RSA密钥对数据签名后，我具有CMS签名。我需要将较长的CMS签名字符串放入qr代码中。但是签名字符串太长，无法生成单个qr。我认为我应该将QR划分为多个区域（在多个QR中）。有没有办法将QR划分为多个区域？

示例：

最近在Java中，我尝试使用zxing库来帮助生成qr代码。但是，它会像其他任何在线服务一样为长字符串引发错误。

QRCodeWriter qrCodeWriter = new QRCodeWriter();
BitMatrix bitMatrix = qrCodeWriter.encode(signedData, 
BarcodeFormat.QR_CODE, 1000, 1000);

File signedFile = new File(id + ".png");

Path path = signedFile.toPath();

MatrixToImageWriter.writeToPath(bitMatrix, "PNG", path);

我希望像Java的链接附件图像一样，从signedData字符串生成多个qrs。
