Is there an out of the box (de)serializer for UUID

问题:

I'm having a problem very similar to what's described here: Combining type and field serializers

case class(id: Option[UUID], otherValue:String, … )

The answer to the related question would allow me to write my own format, but I'm curious if there is already a format for UUID hiding somewhere in json4s. I'd guessed that the right import would solve this issue for UUID, and I was a bit surprised not to find anything.

Did I miss it, or is it not there yet?

回答1:

Since my pull request was merged, there is JavaTypesSerializers.

Usage:

implicit lazy val formats = Serialization.formats(NoTypeHints) ++ 
                            org.json4s.ext.JavaTypesSerializers.all

回答2:

For someone who is looking for a UUID serializer, it has been included in 3.2.11 version of json4s-ext.
