The method getDispatcherType() is undefined for the type HttpServletRequest 升级到tomcat8

配置项目，从tomcat低版本，放到tomcat8时，正常的项目居然报错了：
The method getDispatcherType() is undefined for the type HttpServletRequest
从网上查资料，找可能出现这个问题的因素：
1可能是环境变量，检查了没问题
2有人说jar包冲突
对于servlet-api.jar这个包，原来工程中有，在旧的tomcat版本中，如果不加，会出问题，新的版本中加了会有问题，删除这个包，重启，ok
