Apache POI 异常 [英] Apache POI exception

问题描述

我需要将 docx 转换为 PDF，我将使用 Apache POI.这是我的 POM:

I need to convert a docx to a PDF and I am going with Apache POI. This is my POM:

<dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>4.0.0</version>
    </dependency>
    <dependency>
        <groupId>fr.opensagres.xdocreport</groupId>
        <artifactId>org.apache.poi.xwpf.converter.pdf</artifactId>
        <version>1.0.6</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml -->
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>4.0.0</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-schemas -->
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml-schemas</artifactId>
        <version>4.0.0</version>
    </dependency>


  </dependencies>

出于某种原因，我在转换运行期间遇到异常:

For some reason, I am getting an exception during when the conversion is running:

我用谷歌搜索试图找到我缺少的依赖项是什么，至少我认为是这样，但我找不到有关能够解决我的问题的 POIXMLDocumentPart 的信息.

I googled trying to find what is the dependency I missing, at least I think that's the case, but I can't find information about POIXMLDocumentPart that is able to fix my issue.

这是我用来转换 docx 的方法:

This is the method i am using to convert the docx:

public static void Teste(File file, String destino) {

        try {
            InputStream doc = new FileInputStream(file);
            XWPFDocument document = new XWPFDocument(doc);
            PdfOptions options = PdfOptions.create();
            OutputStream out = new FileOutputStream(new File(destino));
            PdfConverter.getInstance().convert(document, out, options);
            new File(destino);
        } catch(Exception e) {

        }
    }

推荐答案

XDocReport 是针对 POI 3.17 编译的.POI 4.0.0 有一些更改，XDocReport 将无法与 POI 4.0.0 一起使用.POIXMLDocumentPart 移至包 org.apache.poi.ooxml.

XDocReport is compiled against POI 3.17. POI 4.0.0 has some changes and XDocReport will not work with POI 4.0.0. POIXMLDocumentPart moved to the package org.apache.poi.ooxml.

参见 https://github.com/opensagres/xdocreport/pull/324

更新(2019 年 3 月):看起来 XDocReport 2.0.2 已更新为使用 POI 4.0.1.

Update (March 2019): Looks XDocReport 2.0.2 has been updated to use POI 4.0.1.
