Beschreibung
Currently the Jackson ObjectMapper in the
akka.http.javadsl.marshallers.jackson.Jackson class creates a default object mapper which is not configurable.
The only way to override its behaviour is by supplying a custom ObjectMapper everytime the marshaller/unmarshaller is
used.
Akka already provides a way to customise Jackson configuration + retrieving a ObjectMapper
through akka.serialization.jackson.JacksonObjectMapperProvider and the
akka.serialization.jackson {
jackson-modules += "com.acme.MyJacksonModule"
}
configuration. The marshallers/unmarshallers should honour this configuration way. Ideally, we'd have a built-in
public static Route extractObjectMapper(Function<ObjectMapper, Route> inner) {
return extractActorSystem(sys -> {
ObjectMapper objectMapper = JacksonObjectMapperProvider
.get(sys)
.getOrCreate("akka-http",
Optional.empty());
return provide(objectMapper, inner);
});
}
or similar.
