本文介绍了一个项目中使用POI库实现HTML与Word文档(doc、docx)的相互转换，特别强调了在转换过程中图片处理的细节，包括图片路径的解析和大小限制。转换方法包括doc/docx转html以及html转doc/docx，并提供了关键代码片段。

项目后端使用maven，前端使用了富文本编辑器。目前从html转换的word为doc格式，也能将图片进行处理。网上的一些例子好多都是图片无法解析，这个地方千万要注意对图片的路径进行解析，src必须是全路径 域名+图片的正式路径，如果您的需求对图片的大小有限制的话也要修改img的style属性，如果修改完没有效果将style去掉直接加上宽和高。
一.添加maven依赖

	<dependency>
	    <groupId>org.apache.poi</groupId>
	    <artifactId>poi-scratchpad</artifactId>
	    <version>3.14</version>
	</dependency>

二.word转换为html
public static String docToHtml() throws Exception {
File path = new File(ResourceUtils.getURL(“classpath:”).getPath());
String imagePathStr = path.getAbsolutePath() + “\static\image\”;
String sourceFileName = path.getAbsolutePath() + “\static\test.doc”;
String targetFileName = path.getAbsolutePath() + “\static\test2.html”;
File file = new File(imagePathStr);
if(!file.exists()) {
file.mkdirs();
}
HWPFDocument wordDocument = new HWPFDocument(new FileInputStream(sourceFileName));
org.w3c.dom.Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(document);
//保存图片，并返回图片的相对路径
wordToHtmlConverter.setPicturesManager((content, pictureType, name, width, height) -> {
try (FileOutputStream out = new FileOutputStream(imagePathStr + name)) {
out.write(content);
} catch (Exception e) {
e.printStackTrace();
}
return “image/” + name;
});
wordToHtmlConverter.processDocument(wordDocument);
org.w3c.dom.Document htmlDocument = wordToHtmlConverter.getDocument();
DOMSource domSource = new DOMSource(htmlDocument);
StreamResult streamResult = new StreamResult(new File(targetFileName));
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING, “utf-8”);
serializer.setOutputProperty(OutputKeys.INDENT, “yes”);
serializer.setOutputProperty(OutputKeys.METHOD, “html”);
serializer.transform(domSource, streamResult);
return targetFileName;
docx格式转换为html
public static String docxToHtml() throws Exception {
File path = new File(ResourceUtils.getURL(“classpath:”).getPath());
String imagePath = path.getAbsolutePath() + “\static\image”;
String sourceFileName = path.getAbsolutePath() + “\static\test.docx”;
String targetFileName = path.getAbsolutePath() + “\static\test.html”;

OutputStreamWriter outputStreamWriter = null;
try {
    XWPFDocument document = new XWPFDocument(new FileInputStream(sourceFileName));
    XHTMLOptions options = XHTMLOptions.create();
    // 存放图片的文件夹
    options.setExtractor(new FileImageExtractor(new File(imagePath)));
    // html中图片的路径
    options.URIResolver(new BasicURIResolver("image"));
    outputStreamWriter = new OutputStreamWriter(new FileOutputStream(targetFileName), "utf-8");
    XHTMLConverter xhtmlConverter = (XHTMLConverter) XHTMLConverter.getI
