Imports

Simple key generator. Returns the parameter itself if a single non-null value is given, otherwise returns a SimpleKey of the parameters.

No collisions will occur with the keys generated by this class. The returned SimpleKey object can be safely used with a org.springframework.cache.concurrent.ConcurrentMapCache, however, might not be suitable for all org.springframework.cache.Cache implementations.
