推荐答案

有一个 Apache POI 单元测试 涵盖您的情况 - 您正在寻找 TestXWPFHeader#testSetHeader().它涵盖从没有设置页眉或页脚的文档开始，然后添加它们

There's an Apache POI Unit test that covers your very case - you're looking for TestXWPFHeader#testSetHeader(). It covers starting with a document with no headers or footers set, then adding them

您的代码基本上类似于:

Your code would basically be something like:

XWPFHeaderFooterPolicy policy = sampleDoc.getHeaderFooterPolicy();
if (policy.getDefaultHeader() == null && policy.getFirstPageHeader() == null
       && policy.getDefaultFooter() == null) {
   // Need to create some new headers
   // The easy way, gives a single empty paragraph
   XWPFHeader headerD = policy.createHeader(policy.DEFAULT);
   headerD.getParagraphs(0).createRun().setText("Hello Header World!");

   // Or the full control way
    CTP ctP1 = CTP.Factory.newInstance();
    CTR ctR1 = ctP1.addNewR();
    CTText t = ctR1.addNewT();
    t.setStringValue("Paragraph in header");

    XWPFParagraph p1 = new XWPFParagraph(ctP1, sampleDoc);
    XWPFParagraph[] pars = new XWPFParagraph[1];
    pars[0] = p1;

    policy.createHeader(policy.FIRST, pars);
} else {
   // Already has a header, change it
}

请参阅 XWPFHeaderFooterPolicy JavaDocs更多关于创建页眉和页脚的内容.

See the XWPFHeaderFooterPolicy JavaDocs for a bit more on creating headers and footers.

它不是最好的，因此理想情况下它可以使用某种灵魂提交补丁使其更好(提示提示......！)，但它可以像单元测试显示的那样工作

It isn't the nicest, so it could ideally use some kind soul submitting a patch to make it nicer (hint hint...!), but it can work as the unit tests show
