java使用jacob控制office组件实现word、excel、PPT转换成PDF

本文介绍java直接调用Microsoft Office 或 WPS组件实现word、excel、PPT转换成PDF。此方法只适用windows服务器

1. 首先要下载jacob-1.14.3-x64.dll或jacob-1.14.3-x86.dll组件，将组件放到jdk\bin目录下
   下载地址
   网盘下载 提取码：mz4i
2. 配置jacob-1.14.3maven

   <dependency>
   	    <groupId>net.sf.jacob-project</groupId>
   	    <artifactId>jacob</artifactId>
   	    <version>1.14.3</version>
   	</dependency>

3. 实现代码

import com.jacob.com.Variant;

FQA

1.如果office转换成PDF报 com.jacob.com.ComFailException: Can’t get object clsid from progid错误。原因有可能是tomcat配置使用windows服务启动导致，具体原因还没有弄清除。处理方法tomcat将windows服务启动关闭，使用tomcat的脚本启动解决问题。
