The following Java APIs are available to handle OpenXML MS Word documents with Java:
以下 Java API 可用于使用 Java 处理 OpenXML MS Word 文档：
There was one more, but I don't recall the name anymore.
还有一个，但我已经想不起名字了。
As to your functional requirement: merging two documents is technically tricky to achieve the result as the enduser would expect. Most API's won't allow that. You'll need to extract the desired information from two documents and then create one new document based on this information yourself.
至于您的功能要求：合并两个文档在技术上很难达到最终用户期望的结果。大多数 API 不允许这样做。您需要从两个文档中提取所需的信息，然后自己根据这些信息创建一个新文档。

With POI my solution is:
对于 POI，我的解决方案是：
public static void merge(InputStream src1, InputStream src2, OutputStream dest) throws Exception {
OPCPackage src1Package = OPCPackage.open(src1);
OPCPackage src2Package = OPCPackage.open(src2);
XWPFDocument src1Document = new XWPFDocument(src1Package);
CTBody src1Body = src1Document.getDocument().getBody();
XWPFDocument src2Document = new XWPFDocument(src2Package);
CTBody src2Body = src2Document.getDocument().getBody();
appendBody(src1Body, src2Body);
src1Document.write(dest);
}
private static void appendBody(CTBody src, CTBody append) throws Exception {
XmlOptions optionsOuter = new XmlOptions();
optionsOuter.setSaveOuter();
String appendString = append.xmlText(optionsOuter);
String srcString = src.xmlText();
String prefix = srcString.substring(0,srcString.indexOf(">")+1);
String mainPart = srcString.substring(srcString.indexOf(">")+1,srcString.lastIndexOf("<"));
String sufix = srcString.substring( srcString.lastIndexOf("<") );
String addPart = appendString.substring(appendString.indexOf(">") + 1, appendString.lastIndexOf("<"));
CTBody makeBody = CTBody.Factory.parse(prefix+mainPart+addPart+sufix);
src.set(makeBody);
}
With Docx4j my solution is:
使用 Docx4j 我的解决方案是：
public class MergeDocx {
private static long chunk = 0;
private static final String CONTENT_TYPE = "application/vnd.openxmlformats-officedocument.wordprocessingml.document";
public void mergeDocx(InputStream s1, InputStream s2, OutputStream os) throws Exception {
WordprocessingMLPackage target = WordprocessingMLPackage.load(s1);
insertDocx(target.getMainDocumentPart(), IOUtils.toByteArray(s2));
SaveToZipFile saver = new SaveToZipFile(target);
saver.save(os);
}
private static void insertDocx(MainDocumentPart main, byte[] bytes) throws Exception {
AlternativeFormatInputPart afiPart = new AlternativeFormatInputPart(new PartName("/part" + (chunk++) + ".docx"));
afiPart.setContentType(new ContentType(CONTENT_TYPE));
afiPart.setBinaryData(bytes);
Relationship altChunkRel = main.addTargetPart(afiPart);
CTAltChunk chunk = Context.getWmlObjectFactory().createCTAltChunk();
chunk.setId(altChunkRel.getId());
main.addObject(chunk);
}
}

Aspose API is the best so far for merging word doc or docx files so far but that is not free or open source, if you need a free and open source tools there are couple of API you can choose from, you can find a review on them here,
Aspose API 是迄今为止合并 word doc 或 docx 文件的最佳选择，但它不是免费或开源的，如果您需要免费和开源工具，您可以选择几个 API，您可以在他们在这里，
