Servlet.init () initialization error, error generally occurs in the controller, when the same name of the servlet will be reported similar errors,
Cause of the above error:
Controller is not present, there are no controllers referenced
For example: Return "Redirect:/admin/query.action", returns redirect to another controller, but the controller is undefined, the above error will occur!
