这实现不创建图像或链接到他们。这可以
  通过覆盖AbstractWordConverter.processImage（要素被改变，
  布尔，图片）方法

解决方案

作为API文档说：

  

WordToHtmlConverter 不产生图像或它们的链接。这可以
  通过覆盖 AbstractWordConverter.processImage（元素，布尔，资料图片）方法来改变。

如何重写方法，你可以在这里找到：

• I需要的Apache POI图片从Word文档转换为一个HTML文件

您可以尝试使用基于Apache POI XWPF DOCX 2 XHTML转换器：

• XWPFDocument 2 XHTML

您也可以使用的Apache提卡，建的的Apache POI 。其中包括在露天可以在这里找到：

• HTMLRenderingEngine

还有很多其他的转换器。

I want to convert a document .doc that contains some images. How to convert it to *.html, so that the images will remain same position? How to store those images in separate folder named image and use this folder as a source for image?

public class TestWordToHtmlConverter {
    private File docFile;
    private File file;

    public TestWordToHtmlConverter(File docFile) {
        this.docFile = docFile;
    }

    public void convert(File file) {
    this.file = file;

        try {
            FileInputStream finStream=new FileInputStream(docFile.getAbsolutePath()); 
            HWPFDocument doc=new HWPFDocument(finStream);
            WordExtractor wordExtract=new WordExtractor(doc);
            Document newDocument = DocumentBuilderFactory.newInstance() .newDocumentBuilder().newDocument();
            WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(newDocument) ;
            wordToHtmlConverter.processDocument(doc);

            StringWriter stringWriter = new StringWriter();
            Transformer transformer = TransformerFactory.newInstance().newTransformer();

            transformer.setOutputProperty(OutputKeys.INDENT, "yes");
            transformer.setOutputProperty(OutputKeys.ENCODING, "utf-8");
            transformer.setOutputProperty(OutputKeys.METHOD, "html");
            transformer.transform(new DOMSource( wordToHtmlConverter.getDocument()), new StreamResult( stringWriter ) );

            String html = stringWriter.toString();
            FileOutputStream fos=new FileOutputStream(new File("html/sample.html"));
            DataOutputStream dos;

           JScrollPane scrollPane = new JScrollPane(editorPane);

           f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
           f.getContentPane().add(scrollPane);
           f.setSize(512, 342);
           f.setVisible(true);*/

        } catch(Exception e) {
            e.printStackTrace();
        }
    }  

    public static void main(String args[]) {
        TestWordToHtmlConverter TTC=new TestWordToHtmlConverter(new File("docx/sample.doc"));
        TTC.convert(TTC.docFile);         
   }
}

This implementation doesn't create images or links to them. This can be changed by overriding AbstractWordConverter.processImage(Element, boolean, Picture) method

解决方案

As said in API docs:

WordToHtmlConverter doesn't create images or links to them. This can be changed by overriding AbstractWordConverter.processImage(Element, boolean, Picture) method.

How to override method you can found here:

• I need Apache POI Pictures converted from a word document to a html file

You can try using DOCX 2 XHTML converter based on Apache POI XWPF:

• XWPFDocument 2 XHTML

Also you can use Apache Tika, built on top of Apache POI. An example that included in Alfresco can be found here:

• HTMLRenderingEngine

There are also many other converters.
