camel-jackson unmarshalling question
Hi, I had a question about unmarshalling a json object to a generic class
type, such as something like, MyClass<Person>. Due to erasure, Jackson
provides a special way of unmarshalling this type object so that you don't
lose the generic type information, like this:
MyClass<Person> myClass = mapper.readValue(json, new
TypeReference<MyClass<Person>>() {});
Is there anyway to do this with the camel dataformat dsl? Or does the
unmarshalling have to be done manually someway?
Thanks for help in advance!

Thanks for your response Claus! I think it would be a useful feature..
Maybe I'll try to figure it out one of these days so I can contribute it.

Good point, I forgot I could probably utilize tannotations to do it for
now. :)

It can probably be done by adding jackson annotations:

Hi
No this is not supported today.
Though we could maybe add that, so you can configure this on the data format.
