[需求] Is better for FastBeanCopier change CACHE type to ConcurrentReferenceHashMap

[Taoaozw]

f in a scenario where the key changes frequently,ConcurrentHashMap takes up a lot of invalid memory

I don't think so ,Creating Copier is time-consuming, and using ConcurrentHashMap may speed up program crashes!

emmm, maybe you say ConcurrentReferenceHashMap will speed up program crashes ? FastBeanCopier exactly use ConcurrentHashMap here ! You have a point, It's cost-effective to have high performance requirements ! But the situations of out-of-memory situations also need to be considered , is there can provider a choose .

[zhou-hao]

You are right , It should be configurable , can you pull request to do it ?

Thanks for your invitation , i will try do this !
