Usage

From source file:javaapplication1.utils.MyWordToHtml.java

public static void convert(String path, String file) throws Throwable {
    InputStream input = new FileInputStream(path + file);
    HWPFDocument wordDocument = new HWPFDocument(input);
    WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(
            DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
    MyPictureManager pictureManager = new MyPictureManager();
    wordToHtmlConverter.setPicturesManager(pictureManager);

    wordToHtmlConverter.processDocument(wordDocument);
    List<?> pics = wordDocument.getPicturesTable().getAllPictures();
    File dir = new File("D:\\pics");
    dir.mkdir();/*from   ww w  .j  ava  2  s  . c  o m*/
    if (pics != null) {
        for (int i = 0; i < pics.size(); i++) {
            Picture pic = (Picture) pics.get(i);
            try {
                pic.writeImageContent(new FileOutputStream(path + "pics/" + pic.suggestFullFileName()));
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
        }
    }
    Document htmlDocument = wordToHtmlConverter.getDocument();
    ByteArrayOutputStream outStream = new ByteArrayOutputStream();
    DOMSource domSource = new DOMSource(htmlDocument);
    StreamResult streamResult = new StreamResult(outStream);

    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);
    outStream.close();

    String content = new String(outStream.toByteArray());

    writeFile(content, path + "result.html", "UTF-8");
}
