Java 使用documents4j将docx转换为pdf抛出异常

我正在尝试使用documents4j库为docx编写一个到pdf的转换器。有没有missiong图书馆？这可能是文档4J库的限制吗

这是我正在使用的依赖项：

<dependency>
        <groupId>com.documents4j</groupId>
        <artifactId>documents4j-api</artifactId>
        <version>1.0.3</version>
    </dependency>

    <dependency>
        <groupId>com.documents4j</groupId>
        <artifactId>documents4j-util-conversion</artifactId>
        <version>1.0.3</version>
    </dependency>

    <dependency>
        <groupId>com.documents4j</groupId>
        <artifactId>documents4j-transformer</artifactId>
        <version>1.0.3</version>
    </dependency>

    <dependency>
        <groupId>com.documents4j</groupId>
        <artifactId>documents4j-util-all</artifactId>
        <version>1.0.3</version>
    </dependency>

    <dependency>
        <groupId>com.documents4j</groupId>
        <artifactId>documents4j-local</artifactId>
        <version>1.0.3</version>
    </dependency>

我得到以下例外

java.lang.IllegalStateException: The application was started without any registered or class-path discovered converters.

您是否定义了临时路径？是的，临时路径存在。。。。并且需要在服务器上安装ms office。确实，请在linux和windows环境tnx上使用此转换器，但它不支持波斯语和从右到左的语言。：）
