下面的代码不适用于apache poi 3.16。有人能提供正确的解决方案吗？在我的项目中，有一些依赖项只能使用

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());
    }
}

例外情况：

这方面的主要问题是 PdfOptions 及 PdfConverter 不属于 apache poi 项目它们是由 opensagres 第一个版本的名字很糟糕 org.apache.poi.xwpf.converter.pdf.PdfOptions 及 org.apache.poi.xwpf.converter.pdf.PdfConverter . 这些旧类自2014年以来未更新，需要更新版本 3.9 属于 apache poi 待使用。
请使用更流行的fr.opensagres.poi.xwpf.converter.pdf，它使用最新的稳定版本 apache poi 3.17 .
那就做吧

import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.File;

//needed jars: fr.opensagres.poi.xwpf.converter.core-2.0.1.jar, 
//             fr.opensagres.poi.xwpf.converter.pdf-2.0.1.jar,
//             fr.opensagres.xdocreport.itext.extension-2.0.1.jar,
//             itext-2.1.7.jar                                  
import fr.opensagres.poi.xwpf.converter.pdf.PdfOptions;
import fr.opensagres.poi.xwpf.converter.pdf.PdfConverter;

//needed jars: apache poi and it's dependencies
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class DOCXToPDFConverterSampleMin {

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

  String docPath = "./WordDocument.docx";
  String pdfPath = "./WordDocument.pdf";

  InputStream in = new FileInputStream(new File(docPath));
  XWPFDocument document = new XWPFDocument(in);
  PdfOptions options = PdfOptions.create();
  OutputStream out = new FileOutputStream(new File(pdfPath));
  PdfConverter.getInstance().convert(document, out, options);

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

 }
}

2018年10月：此代码使用 apache poi 3.17 . 它无法使用 apache poi 4.0.0 由于环境的变化 apache poi 这些都没有被考虑在内 fr.opensagres.poi.xwpf.converter 直到现在。
2019年2月：使用最新的 apache poi 版本 4.0.1 还有最新的版本 2.0.2 由fr.opensagres.poi.xwpf.converter.core和consorts组成。
2021年6月：使用 apache poi 版本 4.1.2 还有最新的版本 2.0.2 由fr.opensagres.poi.xwpf.converter.core和consorts组成。无法使用 apache poi 版本 5.0.0 因为 XDocReport 需要 ooxml-schemas 哪个 apache poi 5 不再支持。

fr.opensagres.poi.xwpf.converter.core的新版本2.0.2使用apache poi 4.0.1和itext 2.17运行。您只需要在maven中添加以下依赖项，然后maven将自动下载所有依赖项(更新了maven项目，因此它下载了所有这些库及其所有依赖项）

<dependency>
    <groupId>fr.opensagres.xdocreport</groupId>
    <artifactId>fr.opensagres.poi.xwpf.converter.pdf</artifactId>
    <version>2.0.2</version>
</dependency>

刚刚添加到pox.xml中

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>4.0.0</version>
</dependency>
<dependency>
    <groupId>fr.opensagres.xdocreport</groupId>
    <artifactId>fr.opensagres.poi.xwpf.converter.pdf</artifactId>
    <version>2.0.2</version>
</dependency>
