HttpMethodConstraint: Specific security constraints can be applied to different types of request, differentiated by the HTTP protocol method type by using this annotation inside the `ServletSecurity` annotation.
MultipartConfig: This annotation is used to indicate that the `Servlet` on which it is declared expects requests to made using the `multipart/form-data` MIME type.
