使用Apache POI在Java中将.doc转换为.html

3

我希望将包含一些图片的文档.doc转换为*.html文件，以便图片保持原来的位置。如何将这些图片存储在名为image的单独文件夹中，并将此文件夹用作图像源？

我的代码：

import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;

import org.apache.poi.xwpf.converter.xhtml.XHTMLOptions;
import org.w3c.dom.Document;

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;

            try {
                BufferedWriter out = new BufferedWriter(new OutputStreamWriter(fos,"UTF-8"));    
                out.write(html);
                out.close();
            }
            catch (IOException e) {
               e.printStackTrace();
            }

           /*JEditorPane editorPane = new JEditorPane();
           editorPane.setContentType("text/html");
           editorPane.setEditable(false);

           editorPane.setPage(file.toURI().toURL());

           JScrollPane scrollPane = new JScrollPane(editorPane);     
           JFrame f = new JFrame("Display Html File");
           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);         
   }
}

该实现不会创建图像或链接到它们。这可以通过覆盖AbstractWordConverter.processImage(Element, boolean, Picture)方法来更改。

如API文档所述：

WordToHtmlConverter不会创建图像或链接到它们。可以通过覆盖AbstractWordConverter.processImage(Element, boolean, Picture)方法来改变这一点。

如何覆盖方法可以在此处找到：

我需要将Apache POI图片从Word文档转换为HTML文件

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

XWPFDocument 2 XHTML

此外，您还可以使用建立在Apache POI之上的Apache Tika。这里有一个包含在Alfresco中的示例：

HTMLRenderingEngine

还有许多其他转换器可供使用。
