word、excel、ppt转PDF文件

今天项目要求做个word、excel转pdf的功能，百般搜刮，测试，终于完成.

下面这个是word、excel、ppt转pdf功能，支持doc、docx、xls、xlsx、ppt、pptx转pdf

1、准备工作：windows环境、maven项目，普通项目也可以

下载jacob.zip，地址: https://sourceforge.net/projects/jacob-project/

2、点击 download 就行，下载解压后显示的是 jacob-1.19文件这个样子

3、 64位系统就用 x64的dll，32位系统就用x86的dll。将dll文件放入放入jdk/bin目录下,如下图所示：

4、将压缩包中的jacob.jar引入项目

<dependency>
         <groupId>com.google.guava</groupId>
         <artifactId>guava</artifactId>
         <version>19.0</version>
</dependency>
    
<dependency>
       <groupId>com.jacob</groupId>
       <artifactId>jacob</artifactId>
       <version>1.18-M2</version>
       <scope>system</scope>
       <systemPath>D:\Maven\maven-repository\jacob\jacob.jar</systemPath>
</dependency>

5、上代码
