Convert DOCX to HTML incliding IMAGES

问题

I am using DOCX4J to convert the DOCX to HTML .I have successfully done the conversion and got the html format.I will be using the html format to embed it as EMAIL body to send an email.But I have some issues which are listed below....

Unable to display images in email body
Losing the spaces and bullets

Please find the code which I have written,

WordprocessingMLPackage wordMLPackage;
wordMLPackage = Docx4J.load(new java.io.File(resourcePath2));
HTMLSettings htmlSettings = Docx4J.createHTMLSettings();
htmlSettings.setImageDirPath(imageFolder + resourcePath2 + "_files"); 
htmlSettings.setImageTargetUri(imageFolder +resourcePath2.substring(resourcePath2.lastIndexOf("/")+1) + "_files");
htmlSettings.setWmlPackage(wordMLPackage);

OutputStream os; 
os = new ByteArrayOutputStream();
Docx4jProperties.setProperty("docx4j.Convert.Out.HTML.OutputMethodXML", true);
Docx4J.toHTML(htmlSettings, os, Docx4J.FLAG_SAVE_FLAT_XML);
DOCX = ((ByteArrayOutputStream)os).toString();

You may add like this in your code

package tcg.doc.web.managedBeans;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import org.apache.poi.xwpf.converter.core.FileImageExtractor;
import org.apache.poi.xwpf.converter.core.FileURIResolver;
import org.apache.poi.xwpf.converter.xhtml.XHTMLConverter;
import org.apache.poi.xwpf.converter.xhtml.XHTMLOptions;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;

@Component
@Scope("session")
@Qualifier("ConvertWord")


public class ConvertWord {
    private static final String docName = "TestDocx.docx";
    private static final String outputlFolderPath = "d:/";


    String htmlNamePath = "docHtml.html";
    String zipName="_tmp.zip";
    File docFile = new File(outputlFolderPath+docName);
    File zipFile = new File(zipName);




      public void ConvertWordToHtml() {

          try {

                // 1) Load DOCX into XWPFDocument
                InputStream doc = new FileInputStream(new File(outputlFolderPath+docName));
                System.out.println("InputStream"+doc);
                XWPFDocument document = new XWPFDocument(doc);

                // 2) Prepare XHTML options (here we set the IURIResolver to load images from a "word/media" folder)
                XHTMLOptions options = XHTMLOptions.create(); //.URIResolver(new FileURIResolver(new File("word/media")));;

                // Extract image
                String root = "target";
                File imageFolder = new File( root + "/images/" + doc );
                options.setExtractor( new FileImageExtractor( imageFolder ) );
                // URI resolver
                options.URIResolver( new FileURIResolver( imageFolder ) );


                OutputStream out = new FileOutputStream(new File(htmlPath()));
                XHTMLConverter.getInstance().convert(document, out, options);


                System.out.println("OutputStream "+out.toString());
            } catch (FileNotFoundException ex) {

            } catch (IOException ex) {

            } 
         }

      public static void main(String[] args) {
         ConvertWord cwoWord=new ConvertWord();
         cwoWord.ConvertWordToHtml();
         System.out.println();
    }



      public String htmlPath(){
        // d:/docHtml.html
          return outputlFolderPath+htmlNamePath;
      }

      public String zipPath(){
          // d:/_tmp.zip
          return outputlFolderPath+zipName;
      }

}

For maven Dependency on pom.xml

<dependency>
  <groupId>fr.opensagres.xdocreport</groupId>
  <artifactId>org.apache.poi.xwpf.converter.xhtml</artifactId>
  <version>1.0.4</version>
</dependency>

For images to work in an email body, I guess you need to use either a data URI or publish them to a web-reachable location.

In either case, you'll need to write an implementation of:

public interface ConversionImageHandler {

/**
 * @param picture 
 * @param relationship of the image 
 * @param part of the image, if it is an internal image, otherwise null
 * @return uri for the image we've saved, or null
 * @throws Docx4JException this exception will be logged, but not propagated
 */
public String handleImage(AbstractWordXmlPicture picture, Relationship relationship, BinaryPart part) throws Docx4JException;
}

and configure docx4j to use it with htmlSettings.setImageHandler.

You can look at some of the existing implementations in the docx4j source code, and take advantage of the helper methods in AbstractConversionImageHandler (eg createEncodedImage if you want data URIs).
