How to use InjectableValues (for properties annotated as @JacksonInject) when using Spring RestTemplate?

Question

Jackson's @JacksonInject annotation is useful for declaring properties of your deserialized object that are to be "injected" by the code calling for deserialization (as opposed to only being parsed from the JSON). To use this feature, it seems you have to either:

1. Set the InjectableValues into the ObjectMapper (which would tie them to that ObjectMapper instance and be used for all calls to it).
2. Get an ObjectReader [via ObjectMapper.reader(InjectableValues)] and use that ObjectReader directly to parse the JSON.

Unfortunately, neither of these is doable (from what I can see) when using Spring's RestTemplate without jumping through a lot of hoops. I don't want every object being deserialized from the RestTemplate to use injected values; nor do I see a way to customize how RestTemplate uses the underlying ObjectMapper¹.

Is there a way to incorporate InjectableValues into RestTemplate's JSON deserialization?

¹I suppose I could write my own custom HttpMessageConverter and figure out how to inject that into RestTemplate. But even then I don't see a way to pass the InjectableValues into ObjectMapper's read... methods. It's a lot of work even if I could.
