java 中的 Docx 到 Pdf 转换器

Question

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，在我的项目中有一些只使用

的依赖项

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());
    }
}

异常：

Answer 1

主要问题是 PdfOptions 和 PdfConverter 不是 apache poi 项目的一部分。它们由 opensagres 开发，第一个版本的名字很糟糕 org.apache.poi.xwpf.converter.pdf.PdfOptions 和 org.apache.poi.xwpf.converter.pdf.PdfConverter。那些旧的类自 2014 年以来未更新，需要使用 apache poi 的 3.9 版本。

使用最新的 fr.opensagres.poi.xwpf.converter.pdf，它使用最新的稳定版本 apache poi 3.17。

然后做

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 有效。它无法使用 apache poi 4.0.0，因为 apache poi 中的更改直到现在才在 fr.opensagres.poi.xwpf.converter 中考虑。

2019 年 2 月：现在为我工作，使用最新的 apache poi 版本 4.0.1 和 fr.opensagres.poi.xwpf.converter.pdf 的最新版本 2.0.2 and consorts.

2021 年 6 月：使用 apache poi 版本 4.1.2 和 fr.opensagres.poi.xwpf.converter.pdf 的最新版本 2.0.2 和 consorts。无法使用 apache poi 版本 5.0.0 因为 XDocReport 需要 ooxml-schemas 而 apache poi 5 不再支持。

2022 年 4 月：使用 apache poi 版本 5.2.2 和 fr.opensagres.poi.xwpf.converter.pdf 的最新版本 2.0.3 和 consorts。

Answer 2

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>

Answer 3

刚刚添加到 POX.xml

<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>

Answer 4

June 2021: Works using apache poi version 4.1.2 and the newest version 2.0.2 of fr.opensagres.poi.xwpf.converter.core and consorts. Cannot work using apache poi version 5.0.0 because XDocReport needs ooxml-schemas which apache poi 5 does not support anymore.

ooxml-schemas 已替换为 poi-ooxml-full.

https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-full/5.0.0

但它不适用于 fr.opensagres.poi.xwpf.converter.core 2.0.2，因为它与 apache-poi 5.0.0 中包含的新版本 CTStyle 不兼容.
