Disable JsonIdentityInfo serialization

[jwgmeligmeyling]

Some clients may not support @JsonIdentityInfo. It would then be convenient to disable this feature on a ObjectMapper level.

I've found this question asked before on Stack Overflow: https://stackoverflow.com/questions/29991236/ignore-the-jackson-jsonidentityinfo-during-serialization . The suggested solution there is to use a JacksonAnnotationIntrospector to ignore the @JsonIdentityInfo annotations. I don't think there has been a response from the contributors however, and I am looking for alternative solutions that are a bit more flexible?

Would it be an idea to introduce a SerializationFeature.USE_OBJECT_ID? Or perhaps a @JsonIdentityReference(neverAsId = true) for deserialisation use-cases that rely on a ObjectIdResolver.

To me, use of AnnotationIntrospector is the way to go, and I am not sold on adding features to disable things that are explicitly marked via annotations. If Object Ids are not to be used, @JsonIdentityInfo should not be added.

Another possibility for "optional" use are mix-in annotations: @JsonIdentityInfo annotation may be added via mix-in just like any other Jackson annotation; so adding to a base class when needed could work.

Fair, in retrospect I guess I was kind of abusing JsonIdentityReference for its deserialisation possibilities with resolver and I ended up writing custom Deserializers and a BeanDeserializerModifier to get the job done instead 👍🏻
