我有一个 XFDF 文件包含一些注释但不包含字段，我想知道它是否能够使用 PDFBox 将这些注释导入 PDF 文件

我已尝试在 Acrobat Reader DC 中将 XFDF 导入 PDF 并成功显示导入的注释。但是，通过在 PDAcroForm 中使用函数 importFDF 来显示注释并不成功。它只导入字段但不导入注释。

下面是我的示例 XFDF

加载 xfdf 文件后，从 FDAnnotation 获取 COSObject，然后使用它创建一个 PDAnnotation

PDAnnotation pdfannot = PDAnnotation.createAnnotation(fdfannot.getCOSObject());

然后添加到页面

List<PDAnnotation> pdfannots = new ArrayList<PDAnnotation>;
pdfannots.add(pdfannot);
page.setAnnotations(pdfannots);

保存它，您将在 PDF 上看到注释
