找不到字体：
第一次启动应用程序时会出现这种情况，我尝试升级到3.0.2和3.0.3但仍然无法解决 以及在 docker 容器中运行的应用程序。
总结我的评论： 第一次从磁盘需要字体时，PDFBox 会构建一个包含字体信息的缓存文件，这可能需要很长时间。如果字体损坏，旧版 PDFBox 版本有时会中止，或者尝试一次又一次地访问该字体，因此请确保您使用的是 PDFBox 3.0.3 或 2.0.32。
如果您在 docker 这样的容器内使用 PDFBox，请考虑在启动容器之前构建字体信息缓存文件（
.pdfbox.cacheFontMappers.instance().getFontBoxFont("Arial", null);
