使用poi 4.1.2版本生成doc转html代码

以下是使用poi 4.1.2版本生成doc转html代码的示例：

import java.io.*;

import org.apache.poi.hwpf.extractor.WordExtractor;
import org.apache.poi.hwpf.usermodel.*;
import org.apache.poi.util.IOUtils;
import org.apache.poi.xwpf.converter.core.BasicURIResolver;
import org.apache.poi.xwpf.converter.core.FileImageExtractor;
import org.apache.poi.xwpf.converter.core.IURIResolver;
import org.apache.poi.xwpf.converter.core.XWPFConverterException;
import org.apache.poi.xwpf.converter.html.*;
import org.apache.poi.xwpf.usermodel.*;

public class DocToHtmlConverter {
    public static void main(String[] args) {
        try {
            // Create a FileInputStream for the doc file
            FileInputStream fis = new FileInputStream("input.doc");

            // Create a WordExtractor object
            WordExtractor extractor = new WordExtractor(fis);

            // Extract the text from the doc file
            String text = extractor.getText();

            // Create a FileWriter object for the output file
            FileWriter writer = new FileWriter("output.html");

            // Write the text to the output file
            writer.write(text);

            // Close the input stream and output writer
            fis.close();
            writer.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

注意：以上示例仅适用于生成doc转html，如果要生成docx转html，则需要使用`XWPFDocument`和相关类，具体示例可以参考poi官方文档。
