java - 如何将长字符串拆分为多个 qr 区域？

Question

用 RSA 密钥签署数据后，我有一个 CMS 签名。我需要将那长长的 CMS 签名字符串放入二维码中。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 qrs 中）。有没有办法将qr分成多个区域？

例子：

最近在Java中我尝试使用可以帮助生成二维码的zxing库。但它会像您可以尝试的任何其他在线服务一样引发长字符串错误。

String signedData = "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";

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);

我期望从signedData 字符串生成多个qrs，如Java 中的链接附件图像。
