Java中的Docx至Pdf转换器

以下代码不适用于Apache poi 3.16。有人可以提供正确的解决方案吗，在我的项目中，有些人只能使用

public void ConvertToPDF(String docPath, String pdfPath) {
    try {
        InputStream doc = new FileInputStream(new File(docPath));
        XWPFDocument document = new XWPFDocument(doc);
        PdfOptions optiOns= PdfOptions.create();
        OutputStream out = new FileOutputStream(new File(pdfPath));
        PdfConverter.getInstance().convert(document, out, options);
        System.out.println("Done");
    } catch (FileNotFoundException ex) {
        System.out.println(ex.getMessage());
    } catch (IOException ex) {
        System.out.println(ex.getMessage());
    }
}

例外：

这样做的主要问题是这些PdfOptions和PdfConverter不是apache poi项目的一部分。它们是由开发的opensagres，第一个版本的命名错误org.apache.poi.xwpf.converter.pdf.PdfOptions和org.apache.poi.xwpf.converter.pdf.PdfConverter。这些老班没有更新从2014年开始，需要版本3.9 的 apache poi使用。

请使用更多 最新版本的fr.opensagres.poi.xwpf.converter.pdf，该版本可以使用最新的稳定版本进行工作apache poi 3.17。

然后做

  OutputStream out = new FileOutputStream(new File(pdfPath));
  PdfConverter.getInstance().convert(document, out, options);

  document.close();
  out.close();

 }
}

2018年10月：此代码可使用apache poi 3.17。apache poi 4.0.0由于到目前为止apache poi尚未考虑到更改，因此无法使用fr.opensagres.poi.xwpf.converter。

2019年2月：对我的作品现在使用的最新apache poi版本4.0.1和最新版本2.0.2的fr.opensagres.poi.xwpf.converter.core和配偶。
