The Spring Boot starter adds the `AnnotatedControllerConfigurer` by default.
NOTE: Unlike web frameworks, GraphQL does not use Jackson annotations to drive JSON serialization/deserialization.
Custom data types and their serialization https://www.graphql-java.com/documentation/scalars/[must be described as Scalars].
