java poi解析Excel2007+版本报错原因和解决办法

错误信息org.apache.poi.openxml4j.exceptions.InvalidFormatException

报错原因：
1、jar包冲突；
2、jar包版本过高；
我的原因就是jar包的版本过高，后引入poi3.11版本的jar包；
这里提供完整版本，其中包括poi所需的所有包

通过createworkbook方法创建WorkBook，获取03和07版本不同的类型，解决其报InvalidFormatException的错误！
这个工具类实现的是将Excel文件解析后以表头为key，存储数据。数据格式是List>！
