According
to http://doc.akka.io/docs/akka-http/10.0.5/java/http/common/json-support.html
we have to use
akka.http.javadsl.marshallers.jackson.Jackson.marshaller(T.class)
But this method does not exists anymore.
akka.http.javadsl.marshallers.jackson.Jackson.marshaller()
akka.http.javadsl.marshallers.jackson.Jackson.marshaller(ObjectMapper o)
