I use this code.

我用这个代码。

private byte[] toPdf(ByteArrayOutputStream docx) {
    InputStream isFromFirstData = new ByteArrayInputStream(docx.toByteArray());

    XWPFDocument document = new XWPFDocument(isFromFirstData);
    PdfOptions options = PdfOptions.create();

    //make new file in c:\temp\
    OutputStream out = new FileOutputStream(new File("c:\tmp\HelloWord.pdf"));
    PdfConverter.getInstance().convert(document, out, options);

    //return byte array for return in http request.
    ByteArrayOutputStream pdf = new ByteArrayOutputStream();
    PdfConverter.getInstance().convert(document, pdf, options);

    document.write(pdf);
    document.close();
    return pdf.toByteArray();

Only ONE dependency needs to manually added (the others should be pulled in automatically). As of right now, the latest version is 2.0.2.

仅需要手动添加一个依赖项（其他依赖项应自动拉入）。截至目前，最新版本是 2.0.2。

Gradle:

摇篮：

dependencies {
    // What you should already have
    implementation "org.apache.poi:poi-ooxml:latest.release"


    // ADD THE BELOW LINE TO DEPENDENCIES BLOCK IN build.gradle
    implementation 'fr.opensagres.xdocreport:fr.opensagres.poi.xwpf.converter.pdf:2.0.2'
}

Maven only:

I will provide 3 methods to convert docx to pdf :

我将提供 3 种将 docx 转换为 pdf 的方法：

1. Using itext and opensagres and apache poi

1. 使用 itext 和 opensagres 和 apache poi

Code :

代码 ：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import fr.opensagres.poi.xwpf.converter.pdf.PdfOptions;
import fr.opensagres.poi.xwpf.converter.pdf.PdfConverter;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class ConvertDocToPdfitext {

    public static void main(String[] args) {
  System.out.println( "Starting conversion!!!" );
  ConvertDocToPdfitext cwoWord = new ConvertDocToPdfitext();
   cwoWord.ConvertToPDF("C:/Users/avijit.shaw/Desktop/testing/docx/Account Opening Prototype Details.docx", "C:/Users/avijit.shaw/Desktop/testing/docx/Test-1.pdf");
   System.out.println( "Ending conversion!!!" );
}

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);
    } catch (IOException ex) {
        System.out.println(ex.getMessage());
    }
}

}

}

New version 2.0.2 of fr.opensagres.poi.xwpf.converter.core runs with apache poi 4.0.1 and itext 2.17. You just need to add below dependency in Maven and then maven will auto download all dependent dependencies. (Updated your Maven project, so it downloaded all these libraries and all of its dependencies)

fr.opensagres.poi.xwpf.converter.core 的新版本 2.0.2 与 apache poi 4.0.1 和 itext 2.17 一起运行。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。（更新了您的 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>
