Combining type and field serializers

Question

Let\'s assume I have a case class with the following setup:

case class Place(id:java.util.UUID, name:String)

I can write a (working!) seria

Answer 1

There is now a UUID serializer provided in the extras package of json4s. It will most likely be available in version 3.2.11 (which has not been released as of this writing).

You'll be able to do something like this:

import org.json4s.ext.JavaTypesSerializers

implicit val json4sFormats = Serialization.formats(NoTypeHints) ++ JavaTypesSerializers.all

This was taken from the tests for this feature's PR.
