本文介绍了一种将Word文档转换为HTML的方法，包括处理Word 2003和2007及以上版本。对于Word 2007及更高版本，通过读取InputStream，使用XHTMLConverter将.docx文件转换为HTML，并将图片转换为base64编码内嵌于HTML中。对于Word 2003，使用WordToHtmlConverter处理.doc文件，同样将图片作为base64编码插入HTML。

word转html，图片转为base64，预览

public class InlineImageWordToHtmlConverter extends WordToHtmlConverter {

public InlineImageWordToHtmlConverter(Document document) {
    super(document);
}

@Override
protected void processImageWithoutPicturesManager(Element currentBlock,
                                                  boolean inlined, Picture picture)
{
    Element imgNode = currentBlock.getOwnerDocument().createElement("img");
    StringBuilder sb = new StringBuilder();
    sb.append(Base64.getMimeEncoder().encodeToString(picture.getRawContent()));
    sb.insert(0, "data:"+picture.getMimeType()+";base64,");
    imgNode.setAttribute("src", sb.toString());
    currentBlock.appendChild(imgNode);
}

}
