我正在执行使用API Docx4J将docx文件转换为PDF的操作，但是发现执行转换后很难保持文本的原始格式。

案例文件在此处可用，结果是PDF文件，而DOCX是原始文件。如果有人可以帮助我应对这一挑战，我将不胜感激！

我能够解决我的问题。问题是JBoss一直在寻找自己的依赖关系，因此我不得不为JaxB添加两个依赖关系。依赖关系如下：

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.2.11</version>
</dependency>

    <artifactId>jaxb-runtime</artifactId>
    <version>2.2.11</version>
