ApachePOI-添加页面到docx没有头

日安！请帮我找到解决问题的方法：我需要在文档中添加一个新的QR页面，并将其保存在新目录中的新表单中。我设法做到了，除了一个细微差别。源文档有一个标题，在添加新页面时会自动添加，因为它是默认的。问题是，我不需要在添加了QR的页面中添加此标题，但我需要将其保存在所有其他页面中。我需要有一个没有标题的最后一页。如果我使用这个

XWPFHeaderFooterPolicy policy = document.getHeaderFooterPolicy();
policy.getHeader(XWPFHeaderFooterPolicy.DEFAULT).clearHeaderFooter();

这将删除所有页面上的标题，这是预期的。如果我使用这个：

XWPFParagraph paragraph0 = document.createParagraph();
XWPFParagraph paragraph1 = document.createParagraph();
// Working with paragraphs

XWPFHeaderFooterPolicy policy = document.getHeaderFooterPolicy();

XWPFParagraph[] pars = new XWPFParagraph[2];
pars[0] = paragraph0;
pars[0] = paragraph1;

XWPFHeader header = policy.createHeader(XWPFHeaderFooterPolicy.DEFAULT, pars);
header.clearHeaderFooter();

这发生了完全相同的事情，即从所有页面中删除标头。

请帮我添加一个没有标题的段落的新页面，保留原始文档所有页面的标题。非常感谢！

Microsoft Word中没有仅针对最后一页的页眉/页脚。

在XWPF中POI页脚在最后一页不同，我已经展示了如何设置页脚在最后一页不同。页眉也是如此。

我在链接答案中的代码尽可能短，以显示原理。和这里答案中的所有代码一样，它不被认为可以作为每次复制/粘贴的有效代码使用。它被认为可以用于测试和理解。用于有效使用的代码当然必须包含更多的检查，以考虑真正的Word文档可能使用的所有可能的不同选项。但是这样的代码通常过于宽泛，无法理解原则。

根据您的问题（和评论），要求如下：

打开包含信息和两种类型标题的现有文档（FIRST

所以原理是一样的。我们需要：

为偶数页添加标题，稍后获取最后一节中页面的默认标题。
添加一个段落，其中包含上面第1节的部分设置和部分中断。
添加新部分2的内容。
获取文档中最后一部分的旧部分设置，其中也包含旧的页眉/页脚设置。
将第一个和默认页眉和所有页脚从最后一节移动到新的第1节。
为第1节设置“有一个标题页”以使第一个标题工作。从上一节（现在的第2节）中删除第一个和旧的默认标题引用，并将偶数标题的标题引用设置为最后一节的默认标题引用。
取消最后一节的“有一个标题页”。

下面的完整示例再次展示了这一点。它使用当前apache poi 5.2.2和WordDocumentSource. docx进行了测试并工作，其中包含多个具有默认内容的页面以及第一页和默认页面的页眉/页脚。

如果它不适合您，我需要能够在某处下载您使用的源Word文档。然后我可以得到代码无法使用该文档工作的确切原因。

也许将整个部分属性从下面的部分复制到新插入的部分会更好，而不是复制所有单个部分属性。此外，代码可以更多地划分为单个方法。这在下面的代码示例中完成。为了完整起见，我将保留旧示例。
