java - Apache POI 异常

Question

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

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/poi/POIXMLDocumentPart at org.apache.poi.xwpf.converter.core.styles.XWPFStylesDocument.getFontsDocument(XWPFStylesDocument.java:1477) at org.apache.poi.xwpf.converter.core.styles.XWPFStylesDocument.(XWPFStylesDocument.java:190) at org.apache.poi.xwpf.converter.core.styles.XWPFStylesDocument.(XWPFStylesDocument.java:184) at org.apache.poi.xwpf.converter.core.XWPFDocumentVisitor.createStylesDocument(XWPFDocumentVisitor.java:166) at org.apache.poi.xwpf.converter.core.XWPFDocumentVisitor.(XWPFDocumentVisitor.java:159) at org.apache.poi.xwpf.converter.pdf.internal.PdfMapper.(PdfMapper.java:149) at org.apache.poi.xwpf.converter.pdf.PdfConverter.doConvert(PdfConverter.java:55) at org.apache.poi.xwpf.converter.pdf.PdfConverter.doConvert(PdfConverter.java:38) at org.apache.poi.xwpf.converter.core.AbstractXWPFConverter.convert(AbstractXWPFConverter.java:45) at temp.main.Teste(main.java:30) at temp.main.main(main.java:18) Caused by: java.lang.ClassNotFoundException: org.apache.poi.POIXMLDocumentPart at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 11 more

我用谷歌搜索试图找到我遗漏的依赖项，至少我认为是这样，但我找不到能够解决我的问题的有关 POIXMLDocumentPart 的信息。

这是我用来转换 docx 的方法:

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) {

        }
    }

Answer 1

XDocReport 是针对 POI 3.17 编译的。POI 4.0.0 有一些变化，XDocReport 不适用于 POI 4.0.0。POIXMLDocumentPart 移动到包 org.apache.poi.ooxml。

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

更新(2019 年 3 月):Looks XDocReport 2.0.2 已更新为使用 POI 4.0.1。
