我也犯了类似的错误。在我删除了docx4j依赖之后，就没问题了。
我有个例子。
pom.xml性质
<docx4j-JAXB-Internal.version>8.3.4</docx4j-JAXB-Internal.version>
<docx4j-JAXB-ReferenceImpl.version>8.3.4</docx4j-JAXB-ReferenceImpl.version>
<docx4j-JAXB-MOXy.version>8.3.4</docx4j-JAXB-MOXy.version>
<docx4j-export-fo.version>8.3.4</docx4j-export-fo.version>pom.xml依赖关系
<dependency>
<groupId>org.docx4j</groupId>

public static void docx2Png(String docxPath, String pngPath) throws Exception {
FileInputStream fis = new FileInputStream(docxPath);
WordprocessingMLPackage wordPackage = WordprocessingMLPackage.load(fis);
// font mapper
wordPackage.setFontMapper(IFontHandler.getFontMapper());
FOSettings foSettings = Docx4J.createFOSettings();
foSettings.setApacheFopMime(MimeConstants.MIME_PNG);
foSettings.setOpcPackage(wordPackage);
FopFactoryBuilder fopFactoryBuilder = FORendererApacheFOP.getFopFactoryBuilder(foSettings);
FORendererApacheFOP.getFOUserAgent(foSettings, fopFactoryBuilder.build());
FileOutputStream fos = new FileOutputStream(pngPath);
Docx4J.toFO(foSettings, fos, Docx4J.FLAG_EXPORT_PREFER_XSL);
fos.flush();
fos.close();
fis.close();

docx4j 11.4.5是第一个使用jakarta.xml.bind的版本(与前一个javax.xml.bind不同)。
因此，如果您使用的是docx4j-export版本11.4.5，不要添加jaxb-api v2.4；您需要jakarta.xml.bind:jakarta.xml.bind-api:jar:3.0.1。
不要添加docx4j v6.1.2！
