Apache POI创建的docx文档无法转化成html

Question

当我通过word软件创建文档的时候

FileInputStream fileInputStream = new FileInputStream(sourceFileName);
            //当你确定该文件可信任时使用该方法,避免大文件被误认为是zip炸弹,实际上不推荐上传大文件,会导致资源消耗过快
//            ZipSecureFile.setMinInflateRatio(-1.0d);
            XWPFDocument document = new XWPFDocument(fileInputStream);
            System.out.println(document.getStyles());



            XHTMLOptions options = XHTMLOptions.create().indent(4);
            options.setExtractor(new FileImageExtractor(new File(imgPath)));
            options.URIResolver(new BasicURIResolver(imgPath));
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            XHTMLConverter.getInstance().convert(document,baos,options);
            baos.close();
            content = baos.toString();

上面这段代码运行是正常的
但是当我通过apache poi创建docx文档的时候,却会提示

Exception in thread "main" org.apache.poi.xwpf.converter.core.XWPFConverterException: java.lang.IllegalStateException: Expecting one Styles document part, but found 0

我创建文档的代码如下:

package WordToHtml;

import org.apache.poi.xwpf.usermodel.ParagraphAlignment;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

import java.io.File;
import java.io.FileOutputStream;

public class CreateDocx {

    public static void main(String[] args) throws Exception {

        XWPFDocument document = new XWPFDocument();
        FileOutputStream out = new FileOutputStream(new File("C:\\demo\\test.docx"));
        XWPFParagraph firstParagraph = document.createParagraph();
        firstParagraph.setAlignment(ParagraphAlignment.LEFT);

        for (int i = 0;i<=50;i++) {
            XWPFRun run = firstParagraph.createRun();
            run.setText("Java POI 生成word文件。"+i);
            run.addBreak();
            run.setColor("696969");
        }
        firstParagraph.setStyle("");


        //把word文档写到输出流
        document.write(out);

    }
}

请问这个是该怎么解决?

Answer 1

相同的代码，可以正常运行，poi版本4.1.1

Answer 2

可以试下Spire.Doc for Java控件，我用来创建过Word文档，效果不错，而且在创建时还支持设置段落的字体格式、对齐方式、段首缩进以及段落间距等。相关代码可参考他们官方教程。
