番石榴的带有更多参数的cacheloader加载方法？

Question

When the CacheLoader loads something for my Key, I need to pass in some initialization information(basically, a property of what is created).

Unfortunately, the load method only takes a Key K. I could overload the Key we use to have an extra field that is not used in the equals/hashcode but that seems a bit ugly. is there another option such that I can pass information for construction or an ability to pass in a callback creation with the property info in my callback already? basically, every time I read from cache, I would pass key and callback.

Answer 1

an ability to pass in a callback creation with the property info in my callback already?

Are you looking for Cache.get(K, Callable<? extends V>) ?
