包路径：net.sf.ehcache.Ehcache
类名称：Ehcache
方法名：getKeysWithExpiryCheck

Ehcache.getKeysWithExpiryCheck介绍

[英]Returns a list of all elements in the cache. Only keys of non-expired elements are returned.

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

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

For large caches - or caches with high-latency storage this method can take a very long time to complete. You should seriously consider whether your usage requires checking for expired keys before choosing to call this method. As this method can take a long time the results may also be significantly out of date by the time the method returns.
[中]返回缓存中所有元素的列表。只返回未过期元素的键。
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。
对于大型缓存或具有高延迟存储的缓存，此方法可能需要非常长的时间才能完成。在选择调用这个方法之前，您应该认真考虑您的使用是否需要检查过期的密钥。由于此方法可能需要很长时间，因此当该方法返回时，结果也可能明显过时。

   }
