1.前言
MS Office2010是可以的，理论上2007版本也可以，博主没试过；
Wps2015是可以的，理论上Wps2016也能用，Wps理论上还兼容MS Office的相关代码，有时间的可以试试；
Wps和Ms Office都需要导入jacob-1.18.jar包，以及将jacob-1.18-x64.dll或者jacob-1.18-x64.dll放置到jdk的bin目录（或者windows的System32/SysWoW64目录下）
而OpenOffice需要导入jodconverter-2.2.1.jar等相关包；
相关包的下载链接，包含实现代码：http://download.csdn.net/detail/huitoukest/9506740
包中的代码可能没有捕获NoClassDefFoundError异常和，建议使用者自行捕获；
