Ehcache.getKeys介绍

[英]Returns a list of all elements in the cache, whether or not they are expired.

The returned keys are unique and can be considered a set.

The List returned is not live. It is a copy.

The time taken is O(n). For large caches - or caches with high-latency storage this method can take a very long time to complete, may cause timeouts if using features such NonStopCache or transactions, and is not guaranteed to give a consistent view of the cache entry set. Usage is highly discouraged.
[中]返回缓存中所有元素的列表，无论它们是否过期。
返回的密钥是唯一的，可以视为一组。
返回的列表不是活动列表。这是一份副本。
所用时间为O（n）。对于大型缓存或具有高延迟存储的缓存，此方法可能需要很长时间才能完成，如果使用非操作缓存或事务等功能，可能会导致超时，并且不能保证提供缓存项集的一致视图。不鼓励使用。
