好的,下面是一个将Word转换为HTML并保存为HTML文件的工具类,包含了处理Word中图片的代码:
```java
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.Base64;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.converter.WordToHtmlConverter;
import org.apache.poi.hwpf.usermodel.Picture;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
public class WordToHtmlConverterUtils {
/**
* 将Word文件转换为HTML并保存为HTML文件
* @param inputWordFilePath Word文件路径
* @param outputHtmlFilePath HTML文件路径
* @throws IOException
*/
public static void convertWordToHtml(String inputWordFilePath, String outputHtmlFilePath) throws IOException {
// 读取Word文件
FileInputStream fis = new FileInputStream(new File(inputWordFilePath));
HWPFDocument doc = new HWPFDocument(fis);
// 创建HTML文档输出流
FileOutputStream fos = new FileOutputStream(new File(outputHtmlFilePath));
Writer writer = new OutputStreamWriter(fos, "utf-8");
// 创建WordToHtmlConverter对象并处理文档
WordToHtmlConverter converter = new WordToHtmlConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
converter.setPicturesManager(new PicturesManager());
converter.processDocument(doc);
// 获取HTML文档并保存
Document htmlDoc = converter.getDocument();
DOMSource domSource = new DOMSource(htmlDoc);
StreamResult streamResult = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING, "UTF-8");
serializer.setOutputProperty(javax.xml.transform.OutputKeys.INDENT, "yes");
serializer.setOutputProperty(javax.xml.transform.OutputKeys.METHOD, "html");
serializer.transform(domSource, streamResult);
// 关闭流
fis.close();
writer.close();
fos.close();
}
/**
* PicturesManager实现类,用于处理Word中的图片
*/
private static class PicturesManager implements org.apache.poi.hwpf.converter.PicturesManager {
public String savePicture(byte[] content, Picture picture, String suggestedName, float widthInches, float heightInches) {
// 将图片转换为Base64编码的字符串
String base64Content = Base64.getEncoder().encodeToString(content);
// 创建<img>元素
Element imgElement = picture.getDocument().createElement("img");
imgElement.setAttribute("src", "data:image/png;base64," + base64Content);
imgElement.setAttribute("width", String.valueOf(picture.getWidth()));
imgElement.setAttribute("height", String.valueOf(picture.getHeight()));
// 将<img>元素添加到文档中
picture.getParentRun().getParentParagraph().insertBefore(imgElement, picture.getParentRun());
// 移除原图片
picture.getParentRun().remove();
return suggestedName;
}
}
}
```
使用时,只需调用`convertWordToHtml`方法并传入Word文件路径和HTML文件路径即可将Word文件转换为HTML并保存。需要注意的是,需要引入Apache POI和Apache XMLBeans库。
