You mentioned in the issue that using an ApplicationEventListener would be a more appropriate way to handle this. Thoughts?

yes, I had sent a pr to resolve this problem with that, but i found another problem that if the resolver is not a bean in spring then we should remove cache manually. this will complicate the resolver's using. however getting bean every time may cost more time than before but it simplifies the using.

the prototype tool bean will also be supported in this way, and probably the time that it costs more is still in a range that user is acceptable.
