有一个名为PDFBox-Layout的库，可以更轻松地添加超链接：

Document document = new Document();

Paragraph paragraph = new Paragraph();
paragraph.addMarkup(
   "This is a link to {link[https://github.com/ralfstuckert/pdfbox-layout]}PDFBox-Layout{link}",
 18f, BaseFont.Helvetica);
document.add(paragraph);

final OutputStream outputStream = new FileOutputStream("link.pdf");
document.save(outputStream);
