您的屏幕截图显示的是脚注。请参阅 XWPFFootnote：“使用 

XWPFDocument.createFootnote()
或 
XWPFFootnotes.createFootnote()
创建新脚注。”并且：“要在段落中创建对脚注的引用，您可以使用指定目标段落 ID 的 
CTFtnEdnRef
创建一个连续段。
XWPFParagraph.addFootnoteReference(XWPFAbstractFootnoteEndnote)
方法可以为您完成此操作。”

在 

Word
中，脚注仅出现在包含应用脚注引用的段落的页面底部。因此，如果您想成为第 2 页上的脚注，那么您需要将脚注引用应用到第 2 页上的某个段落。该段落后面会有一个数字（脚注引用），该数字引用出现在脚上的脚注页面的。
