java中使用libreoffice将word转换成pdf格式

1. 下载libreoffice 2. 配置path路径，F:\Program Files\LibreOffice 5\program  之后cmd窗口执行soffice命令可以打开libreoffice软件 3. 引依赖 <dependency>

            <groupId>commons-io</groupId>

            <artifactId>commons-io</artifactId>

            <version>2.4</version>

</dependency> 4. 代码
