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

  1. public void ConvertToPDF(String docPath, String pdfPath) {
  2.     try {
  3.         InputStream doc = new FileInputStream(new File(docPath));
  4.         XWPFDocument document = new XWPFDocument(doc);
  5.         PdfOptions options = PdfOptions.create();
  6.         OutputStream out = new FileOutputStream(new File(pdfPath));
  7.         PdfConverter.getInstance().convert(document, out, options);
  8.         System.out.println("Done");
  9.     } catch (FileNotFoundException ex) {
  10.         System.out.println(ex.getMessage());
  11.     } catch (IOException ex) {
  12.         System.out.println(ex.getMessage());
  13.     }
  14. }

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

  1. import java.io.InputStream;
  2. import java.io.OutputStream;
  3. import java.io.FileInputStream;
  4. import java.io.FileOutputStream;
  5. import java.io.File;
  7. //needed jars: fr.opensagres.poi.xwpf.converter.core-2.0.1.jar, 
  8. //             fr.opensagres.poi.xwpf.converter.pdf-2.0.1.jar,
  9. //             fr.opensagres.xdocreport.itext.extension-2.0.1.jar,
  10. //             itext-2.1.7.jar                                  
  11. import fr.opensagres.poi.xwpf.converter.pdf.PdfOptions;
  12. import fr.opensagres.poi.xwpf.converter.pdf.PdfConverter;
  14. //needed jars: apache poi and it's dependencies
  15. import org.apache.poi.xwpf.usermodel.XWPFDocument;
  17. public class DOCXToPDFConverterSampleMin {
  19.  public static void main(String[] args) throws Exception {
  21.   String docPath = "./WordDocument.docx";
  22.   String pdfPath = "./WordDocument.pdf";
  24.   InputStream in = new FileInputStream(new File(docPath));
  25.   XWPFDocument document = new XWPFDocument(in);
  26.   PdfOptions options = PdfOptions.create();
  27.   OutputStream out = new FileOutputStream(new File(pdfPath));
  28.   PdfConverter.getInstance().convert(document, out, options);
  30.   document.close();
  31.   out.close();
  33.  }
  34. }

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）

  1. <dependency>
  2.     <groupId>fr.opensagres.xdocreport</groupId>
  3.     <artifactId>fr.opensagres.poi.xwpf.converter.pdf</artifactId>
  4.     <version>2.0.2</version>
  5. </dependency>
