Java使用poi将word转换为html

使用poi将word转换为html，支持doc,docx，转换后可以保持图片、样式。

1.导入Maven包

<dependency>
 <groupId>org.apache.poi</groupId>
 <artifactId>poi</artifactId>
 <version>3.14</version>
</dependency>
<dependency>
 <groupId>org.apache.poi</groupId>
 <artifactId>poi-scratchpad</artifactId>
 <version>3.14</version>
</dependency>
<dependency>
 <groupId>org.apache.poi</groupId>
 <artifactId>poi-ooxml</artifactId>
 <version>3.14</version>
</dependency>
<dependency>
 <groupId>fr.opensagres.xdocreport</groupId>
 <artifactId>xdocreport</artifactId>
 <version>1.0.6</version>
</dependency>
<dependency>
 <groupId>org.apache.poi</groupId>
 <artifactId>poi-ooxml-schemas</artifactId>
 <version>3.14</version>
</dependency>
<dependency>
 <groupId>org.apache.poi</groupId>
 <artifactId>ooxml-schemas</artifactId>
 <version>1.3</version>
</dependency>

2.转换代码

import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.converter.WordToHtmlConverter;
import org.apache.poi.xwpf.converter.core.BasicURIResolver;
import org.apache.poi.xwpf.converter.core.FileImageExtractor;
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.w3c.dom.Document; 

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.OutputKeys;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter; 

public class Test {
  // doc转换为html
  void docToHtml() throws Exception {
    String sourceFileName = "C:\\doc\\test.doc";
    String targetFileName = "C:\\html\\test.html";
    String imagePathStr = "C:\\html\\image\\";
    HWPFDocument wordDocument = new HWPFDocument(new FileInputStream(sourceFileName));
    Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
    WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(document);
    // 保存图片，并返回图片的相对路径
    wordToHtmlConverter.setPicturesManager((content, pictureType, name, width, height) -> {
      try(FileOutputStream out = new FileOutputStream(imagePathStr + name)){
         out.write(content);
      } catch (Exception e) {
        e.printStackTrace();
      }
      return "image/" + name;
    });
    wordToHtmlConverter.processDocument(wordDocument);
    Document htmlDocument = wordToHtmlConverter.getDocument();
    DOMSource domSource = new DOMSource(htmlDocument);
    StreamResult streamResult = new StreamResult(new File(targetFileName)); 

    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);
  }
  // docx转换为html
  public void docxToHtml() throws Exception {
    String sourceFileName = "D:\\ac\\00.docx";
    String targetFileName = "D:\\ac\\test.html";
    String imagePathStr = "D:\\ac\\image\\";
    OutputStreamWriter outputStreamWriter = null;
    try {
      XWPFDocument document = new XWPFDocument(new FileInputStream(sourceFileName));
      XHTMLOptions options = XHTMLOptions.create();
      // 存放图片的文件夹
      options.setExtractor(new FileImageExtractor(new File(imagePathStr)));
      // html中图片的路径
      options.URIResolver(new BasicURIResolver("image"));
      outputStreamWriter = new OutputStreamWriter(new FileOutputStream(targetFileName), "utf-8");
      XHTMLConverter xhtmlConverter = (XHTMLConverter) XHTMLConverter.getInstance();
      xhtmlConverter.convert(document, outputStreamWriter, options);
    } finally {
      if (outputStreamWriter != null) {
        outputStreamWriter.close();
      }
    }
  }
