纯java怎么实现网页在线显示office文档

可以用第三方服务接口实现，但安全性要好，文档不能泄露出去
poi里有个ExcelToHtmlConverter 和 WordToHtmlConverter

这是在网上找的一段代码我没试

HWPFDocumentCore wordDocument = WordToHtmlUtils.loadDoc(new FileInputStream("D:\\temp\\seo\\1.doc"));

WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(
DocumentBuilderFactory.newInstance().newDocumentBuilder()
.newDocument());
wordToHtmlConverter.processDocument(wordDocument);
Document htmlDocument = wordToHtmlConverter.getDocument();
ByteArrayOutputStream out = new ByteArrayOutputStream();
DOMSource domSource = new DOMSource(htmlDocument);
StreamResult streamResult = new StreamResult(out);

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);
out.close();

String result = new String(out.toByteArray());
System.out.println(result);
