我目前正在尝试使用docx4j库将文件从html转换为docx。
我已经使用itext5设法将html转换为pdf，但是由于jaxb，我现在正面临尝试转换为docx的异常。
我的项目使用了maven，所以我试图导入很多库...都是徒劳的...
public static void htmlToDocx(String html_content, String html_filename, String docx_filename)
{
try {
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage();
NumberingDefinitionsPart ndp = new NumberingDefinitionsPart();
wordMLPackage.getMainDocumentPart().addTargetPart(ndp);
ndp.unmarshalDefaultNumbering();
XHTMLImporterImpl xHTMLImporter = new XHTMLImporterImpl(wordMLPackage);
xHTMLImporter.setHyperlinkStyle("Hyperlink");
wordMLPackage.getMainDocumentPart().getContent().addAll(xHTMLImporter.convert(new File(html_filename), null));
File output = new File(docx_filename);
wordMLPackage.save(output);
System.out.println("done");
System.out.println("file path where it is stored is" + " "+ output.getAbsolutePath());
}
catch (Exception e) {
e.printStackTrace();
}
}
这是我应该将html转换为docx的函数：

最后，这是我的例外情况：
{{1}}
也许有人可以帮助我解决此异常...
谢谢， 纪尧姆。
答案 0 :(得分：0)
对于docx4j，您可以选择要使用的JAXB。如果要使用参考实现，请添加：
b [1, 5, 3]
a [1, 2, 3]
进一步查看https://search.maven.org/artifact/org.docx4j/docx4j-JAXB-ReferenceImpl/8.1.0/jar
删除所有您手动添加的部门，然后将其留给Maven进行。
注意：要在Java 8上使用参考实现，您可能需要注意背书的dir机制。使用Java 8，仅使用https://search.maven.org/artifact/org.docx4j/docx4j-JAXB-Internal/8.1.0/jar
可能会更容易注意2：MVN依赖关系：树是你的朋友
