Class WindResolvedCrashDependency

Class Overview

Implements interfaces:

IWindCacheDependency

cache依赖实现,通过该实现解决大并发时cache(memcached)的值突然失效

在value内部设置1个超时值(timeout1), timeout1比实际的cache(memcached)timeout(timeout2)小. 当从cache读取到timeout1发现它已经过期时候,马上延长timeout1并重新设置到cache. 然后再从数据库加载数据并设置到cache中. <note>注意:该方法用回调的方式来获得当前缓存的数据值.</note>
