如何通过apache poi添加评论

我正在尝试通过apache poi api为MS Word文档添加注释。
我通过使用以下方式完成了部分工作：

CTMarkupRange commentStart = paragraph.getCTP().addNewCommentRangeStart(); commentStart.setId(BigInteger.ZERO); XWPFRun run = paragraph.createRun(); run.setText("text"); CTMarkupRange commentEnd = paragraph.getCTP().addNewCommentRangeEnd(); commentEnd.setId(BigInteger.ZERO); CTR ctr = paragraph.getCTP().addNewR(); CTMarkup ctMarkup = ctr.addNewCommentReference(); ctMarkup.setId(BigInteger.ZERO); 

但我不知道如何将它与真正的评论联系起来，我在api文档中找不到它。
有谁知道如何解决它？

在Office OpenXML Word文档（ XWPF ）中， CommentsDocument位于* .docx ZIP存档中的特殊CommentsDocument /word/comments.xml中。 因此，首先我们需要访问此文档。 但到目前为止， XWPFdocument只会在创建时读取该包部分。 既没有写访问权，也没有创建该包部分的可能性。

因此，我们必须首先提供在* .docx ZIP存档中创建包部分/word/comments.xml并获得对它的写访问权的可能性。

在以下示例中，方法MyXWPFCommentsDocument createCommentsDocument(XWPFDocument document)创建包部分/word/comments.xml及其/word/comments.xml关系。 MyXWPFCommentsDocument类是该包部分的包装类，具有对它的写访问权。
