（三）java项目中的文档转换案例实战——Word2003(doc)版本转换为HTML网页

由于在开发中需要适配不同的多端应用，在文件相关处理中也会存在相同的问题，需要将文档转换为不同的格式展示，本节我们主要通过一个小案例实现在java环境下实现 Word2003(doc)转换为HTML用于在线展示。

• 引入word转换为html的pom工具包

	org.apache.poi
	poi-scratchpad
	3.17




	org.apache.poi
	poi-ooxml
	3.17




	fr.opensagres.xdocreport
	fr.opensagres.xdocreport.converter.docx.xwpf
	2.0.1

•  后端转换代码

    @ApiOperation(value = "word2003转换为html")
    @PostMapping(value = "word2003ToHtml")
    public void word2003ToHtml(HttpServletResponse response, @RequestPart("file") MultipartFile file) {
        try {
            InputStream inputStream = file.getInputStream();
            HWPFdocument worddocument = new HWPFdocument(inputStream);
            WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(documentBuilderFactory.newInstance().newdocumentBuilder().newdocument());
            wordToHtmlConverter.processdocument(worddocument);
            document htmldocument = wordToHtmlConverter.getdocument();
            response.reset();
            response.setHeader("Content-Disposition", "inline; filename=" + URLEncoder.encode(IdWorker.getIdStr() + ".html", "UTF-8"));
            ServletOutputStream outputStream = response.getOutputStream();
            DOMSource domSource = new DOMSource(htmldocument);
            StreamResult streamResult = new StreamResult(outputStream);
            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);
            outputStream.flush();
            inputStream.close();
            outputStream.close();
        } catch (IOException ioException) {
            ioException.printStackTrace();
        } catch (ParserConfigurationException e) {
            e.printStackTrace();
        } catch (TransformerException e) {
            e.printStackTrace();
        }
    }

• vue前端代码 

.container {
  padding: 10px;

  .title {
    font-size: 20px;
    font-weight: bold;
  }
}
