记录：java.lang.IllegalStateException: Current request is not of type

异常："java.lang.IllegalStateException: Current request is not of type [org.apache.catalina.servlet4preview.http.HttpServletRequest]: org.apache.catalina.connector.RequestFacade@f3a2876

由于更换了tomcat 出现了这个异常
controller引入的httpservletrequest有问题，引入的是org.apache.catalina.servlet4preview.http.HttpServletRequest，
但实际应该是import javax.servlet.http.HttpServletRequest;
