我可以向单词添加文本和段落，也可以用文本替换任何合并字段，但我需要使用docx4j添加新的合并字段来创建单词模板。我该怎么做？
我是否使用wordMLPackage.getMainDocumentPart().addTargetPart(targetpart);添加合并字段。如果是这样，怎么办？
编辑：
将示例单词上传到 http://webapp.docx4java.org/OnlineDemo/PartsList.html 和表示部件的对象后，我可能需要添加org.docx4j.openpackaging.parts.WordprocessingML.MainDocumentPart 对象？
但我仍然不明白如何添加合并字段。我还生成了以下 xml 以查找我能得到的任何线索：

<w:t>On the Insert tab, the galleries include items that are designed to coordinate with the overall look of your document. You can use these galleries to insert tables, headers, footers, lists, cover pages, and other document building blocks.

<w:t>You can easily change the formatting of selected text in the document text by choosing a look for the selected text from the Quick Styles gallery on the Home tab. You can also format text directly by using the other controls on the Home tab. Most controls offer a choice of using the look from the current theme or using a format that you specify directly.

从这里我可以看到合并字段位于 xml 元素 w：fldSimple 中，所以我可能需要像这样创建这个 xml：
CTSimpleField ctSimple = factory.createCTSimpleField();
ctSimple.setInstr(" MERGEFIELD lastname \* MERGEFORMAT");
RPr RPr = factory.createRPr();
RPr.setNoProof(new BooleanDefaultTrue());
Text t = factory.createText();
t.setValue("fieldValue");
R run = factory.createR();
run.getContent().add(RPr);
run.getContent().add(t);
JAXBElement<CTSimpleField> fldSimple = factory
.createPFldSimple(ctSimple);
任何帮助都会很棒，谢谢！
终于解决了我自己的问题！只需在此处添加，以便比其他陷入相同问题的人都能找到答案。
ObjectFactory factory = Context.getWmlObjectFactory();
CTSimpleField ctSimple = factory.createCTSimpleField();
ctSimple.setInstr(" MergeField fieldValue \* MERGEFORMAT ");
RPr RPr = factory.createRPr();
RPr.setNoProof(new BooleanDefaultTrue());
Text t = factory.createText();
t.setValue("fieldValue");
R run = factory.createR();
run.getRunContent().add(RPr);
run.getRunContent().add(t);
ctSimple.getParagraphContent().add(run);
JAXBElement<CTSimpleField> fldSimple = factory
.createPFldSimple(ctSimple);
// P
P para = factory.createP();
para.getParagraphContent().add(fldSimple);
Body body = factory.createBody();
body.getEGBlockLevelElts().add(para);
wordMLPackage.getMainDocumentPart().addObject(body);
您需要将相关对象添加到现有段落或新段落中。
为此，请将其添加到相关内容列表中。 请阅读docx4j的入门，了解如何做到这一点，然后在遇到困难时用您尝试过的内容更新您的问题。
对于相关对象，您可以上传一个包含相关字段的简短 docx 到 webapp.docx4java.org/OnlineDemo/PartsList.html 然后单击以查看 XML，以及生成它的代码。 请注意，在这种情况下，您需要包含字段"开始"的运行，直到字段"结束"。
如果遇到问题，可以更新问题以显示 XML 和生成的代码。
