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

Posted 2022-01-19 北溟溟

前言

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

<!--word转html https://mvnrepository.com/artifact/org.apache.poi/poi-scratchpad -->

•  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();
