I use Jackson FasterXML product to deserialize JSONs. Now, I noticed in profiler that I got a ton of duplicate strings as a result since every time I receive a JSON it deserialize into an object which always contains some String variable which tells me the Type name. (it's answer to Facebook GraphQL query). Now, naturally, I would prefer for .intern() method to be used during deserialization of this specific method. Is that possible? If so, how?

  • Simplest decision seems to be using of JsonValueInstantiator but in the examples that I found it's only used for the whole Class. Is there some simple way to use it with fields? – Maxim Terletsky Jan 16 '17 at 08:44
