java实现word文档转换成html格式文本

您可以使用Apache POI库来实现将Word文档转换为HTML格式文本。以下是一个简单的Java代码示例：

import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.converter.WordToHtmlConverter;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;

import java.io.*;

public class WordToHtmlConverterExample {
    public static void main(String[] args) {
        String inputFilePath = "input.doc";
        String outputFilePath = "output.html";

        try (InputStream inputStream = new FileInputStream(inputFilePath);
             HWPFDocument document = new HWPFDocument(new POIFSFileSystem(inputStream));
             Writer writer = new BufferedWriter(new FileWriter(outputFilePath))) {

            Range range = document.getRange();
            WordToHtmlConverter converter = new WordToHtmlConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
            converter.processDocument(document);

            org.w3c.dom.Document htmlDocument = converter.getDocument();
            writer.write(htmlDocumentToString(htmlDocument));

        } catch (IOException | ParserConfigurationException e) {
            e.printStackTrace();
        }
    }

    private static String htmlDocumentToString(org.w3c.dom.Document document) throws IOException {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        StringWriter writer = new StringWriter();
        transformer.transform(new DOMSource(document), new StreamResult(writer));
        return writer.toString();
    }
}

请确保在运行代码之前已经将Apache POI库添加到您的项目中。此代码将读取名为`input.doc`的Word文档，并将其转换为HTML格式，并将结果写入名为`output.html`的文件中。

请注意，这只是一个简单的示例，对于更复杂的文档，可能需要额外的处理和调整来保留样式和格式。
