本文介绍了如何在Java环境中使用docx4j库将Word文档转换为PDF，并着重解决了在Linux系统下转换过程中可能出现的中文乱码问题。关键步骤包括在resource目录下添加simsun.ttc字体文件以支持中文显示。

Java使用docx4j转换Word为Pdf

maven导入依赖
编写Java代码

maven导入依赖

		<dependency>
            <groupId>com.itextpdf</groupId>

需要在resource目录添加simsun.ttc字库文件以支持Linux系统转换中文字体

编写Java代码

/**

     * @param pdfPath  导出的PDF文件位置
     * @return 导出的PDF文件位置
     */

            Mapper fontMapper = new IdentityPlusMapper();
            //加载字体文件（解决linux环境下无中文字体问题）
            if (PhysicalFonts.get("SimSun") == null) {
