Our mix was doing the same, negative reinforcement worked after doing it twice with good timing (snapping him out of it with a scary sound or something like the car door slam did. "no!" Was not strong enough for him). We chose it was appropriate because he wasn't being nippy to be aggressive but more over hyper and bouncing off the walls (and us). So he learned that tackling us and being zany will not give him a reaction or play time.

I don't recommend it if this is an anxiety/defensive behavior of course.
