* with value lru, dubbo initialize the instance of this class using {@link LruCacheFactory} to store method's returns value
* to server from store without making method call.

* e.g. 1) <dubbo:service cache="lru" cache.size="5000"/>
* 2) <dubbo:consumer cache="lru" />
*
*
* LruCache uses url's cache.size value for its max store size, if nothing is provided then
