开发环境：windows。请务必在windows操做系统中进行本操做，由于word须要在服务器上转为pdf。java
请在电脑上安装word，注意是安装word，不是安装wps（这一点很是重要）。windows
请在电脑上安装word转pdf的插件：“软件名：SaveAsPDFandXPS”，下载地址：http://download.csdn.net/download/tiandixuanwuliang/10006993服务器
请把系统须要调用的dll文件放置在java环境的jre的bin目录下，例如：C:\Program Files\Java\jdk1.7.0_13\bin\jacob-1.18-x64.dll，（请注意本身电脑32位仍是64位）下载地址：http://download.csdn.net/download/tiandixuanwuliang/10007003app
将jacob.jar放到C:\Windows\System32目录下。同时将其引入的工程文件中。ui
工程中的使用方式以下：spa
