com.itextpdf.commons.exceptions.UnknownProductException:产品pd

Question

我有一个应用程序，使用Itext 7.1.17和排版2.0.9生成阿拉伯语pdf文件我有两个xml许可证文件如下：

1-itext核心许可证.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<license date="*******" issuer="iText Group NV" library="3">
<licensee expire="*******">
<name>*******</name>
<email>*******</email>
<company>*******</company>
<version>7.1</version>
<key>*******</key>
<licensetype>commercial</licensetype>
<signature>*******</signature>
</licensee>
</license>

2-pdfCalligraph license.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<license date="*********" issuer="iText Group NV" library="3">
<licensee expire="*********">
<name>*********</name>
<email>*********</email>
<company>*********</company>
<version>7.1</version>
<key>*********</key>
<licensetype>commercial</licensetype>
<signature>*********</signature>
</licensee>
<product deploymenttype="" expire="*********" licensetype="commercial" major="2" name="pdfCalligraph" platform="java">
<signature>*********</signature>
</product>
</license>

在我的java代码中，在处理pdf之前，我按照如下方式加载许可证文件：

LicenseKey.loadLicenseFile(licensePath + itextkeyCoreFile);
LicenseKey.loadLicenseFile(licensePath + itextkeyPdfCalligraphFile);

上面的代码在7.1.17版本上运行良好，但当升级到itext 7.2.4和排版3.0.1时，我得到以下异常：

我发现，从7.2版本开始，我必须使用json许可证文件而不是xml(应该有一个从xml许可证格式转换为json许可证书格式的指南(此外，我将不得不使用许可基础jar，而不是itext licensekeyjar

Answer 1

正如您所发现的，iText从iText 7.2(以及相应的插件(切换到了JSON许可证密钥。没有办法将XML许可证密钥转换为有效的JSON密钥，所以iText只会为您生成新的许可证密钥。

由于您拥有商业许可证，只需在Jira支持服务台上记录支持请求即可。毕竟，你是在为支持付费，商业客户不需要依赖Stack Overflow社区。
