Cache.iterator介绍

[英]The ordering of iteration over entries is undefined.

During iteration, any entries that are a). read will have their appropriate CacheEntryReadListeners notified and b). removed will have their appropriate CacheEntryRemoveListeners notified.

java.util.Iterator#next() may return null if the entry is no longer present, has expired or has been evicted.
