Docx4j - Docx 到图像的转换

Question

我正在尝试使用 doc4x 将 docx 转换为 png 文件并遇到一些错误。

摇篮条目，

    implementation group: 'jakarta.xml.bind', name: 'jakarta.xml.bind-api', version: '4.0.0-RC3'

Java代码，

public static void main(String args[]) throws Exception {
        String sourceFile = "/Users/test/test1.docx";
        String destFile = "/Users/test/test1.png";
        
        File theFile = new File(sourceFile);
        File outile=new File(destFile);
        WordprocessingMLPackage wordMLPckg = Docx4J.load(theFile);
        OutputStream os = new FileOutputStream(outile);
        FOSettings settings = Docx4J.createFOSettings();
        settings.setWmlPackage(wordMLPckg);
        settings.setApacheFopMime(MimeConstants.MIME_PNG);
        Docx4J.toFO(settings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);
        os.close();
    }

Answer 1

我有一个类似的错误。我删除了docx4j依赖后就ok了。

我有一个例子。

pom.xml 属性

<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 依赖项

<dependency>
    <groupId>org.docx4j</groupId>
    <artifactId>docx4j-JAXB-Internal</artifactId>
    <version>${docx4j-JAXB-Internal.version}</version>
</dependency>
<dependency>
    <groupId>org.docx4j</groupId>

<dependency>

    <artifactId>docx4j-export-fo</artifactId>
    <version>${docx4j-export-fo.version}</version>
</dependency>

docx转png

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();
}

Answer 2

docx4j 11.4.5 是第一个使用 jakarta.xml.bind 的版本（与之前的 javax.xml.bind 相对）。

因此，如果您使用的是 docx4j-export-fo 版本 11.4.5，请不要添加 jaxb-api v2.4；你需要 jakarta.xml.bind:jakarta.xml.bind-api:jar:3.0.1

并且不要添加 docx4j v6.1.2！

Answer 3

我们实际上是您的 Plutext-Enterprise 库的付费客户。

我们正在升级两者docx4j-JAXB-ReferenceImpl和docx4j-export-fo到版本 11.4.9，我们遇到了同样的错误（见下面的堆栈跟踪）。我们已经升级为使用 JAXB 3（下面也包含 Maven 依赖项）。

我们在这里碰壁了。非常感谢任何建议！

调用时出错Docx4J.toFO:
