I read that this error may be due to any depencency mismatch. I tried several versions but I couldn't fix it. I will be very happy if you can help me. Regards, Ferda

回答1:

I am not sure how this is fixed, I was changign some configuration and also spring versions experimentally and

after deleting

<servlet>
    <servlet-name>context</servlet-name>
    <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

and updating the spring version to 4.8, I do not get this error.
