I guess the first thing would be to understand why you think alternate handling is needed: why doesn't method itsel fail if you want to throw an exception? What is the problem in serializing it as null
that you are trying to solve?
Or if you do not want to serialize such value at all, JsonInclude.NON_ABSENT
(or just NON_EMPTY
which cover case of absent) can be used to configure behavior.
Beyond this it could perhaps be possible to allow alternate configuration of default Optional
serializer this module provides, and then allowing passing differently configured instance.
But I want to first understand the problem to solve, before considering solutions.

You are right.
Actually I changed my code to this and dropped the Optional.
return queryUser.execute(id).orElseThrow(HttpStatusException.notFound());
My intention was not only for this use case, but also for other use cases where the developer might want to return something else, like a default value or dummy object instead of null.
But after thinking more deeply, I think all these use cases can be handled by the application code with custom getters when serializing the object and should not be responsibility of the library.
