For a shortcut, how about using "natural"? I'm using this in my ContextResolver: JSONConfiguration.natural().build()
I didn't set out to ignore extra JSON fields, but I know that people were adding a "comments" field to objects that did not have a setComments method and they were not getting an error. Not necessarily a feature in my instance, but it might work for you.
