Json Support
============
akka-http provides support to convert application-domain objects from and to JSON using jackson_ in an
extra artifact.
Integration with other JSON libraries may be supported by the community.
See `the list of current community extensions for Akka HTTP`_.

Json Support via Jackson
------------------------
To make use of the support module, you need to add a dependency on `akka-http-jackson-experimental`.
Use ``akka.http.javadsl.marshallers.jackson.Jackson.jsonAs[T]`` to create a ``RequestVal<T>`` which expects the request
body to be of type ``application/json`` and converts it to ``T`` using Jackson.
See `this example`__ in the sources for an example.
Use ``akka.http.javadsl.marshallers.jackson.Jackson.json[T]`` to create a ``Marshaller<T>`` which can be used with
``RequestContext.completeAs`` to convert a POJO to an HttpResponse.
