线程安全:确保CacheLoader的load和reload方法是线程安全的,因为它们可能会被多个线程并发调用。 异常处理:在load和reload方法中处理可能的异常,以避免缓存处于不一致状态。 性能考虑:虽然异步重新加载可以提高响应性,但过多的异步任务可能会增加系统的负载。因此,需要合理设置缓存的容量和刷新策略。 缓存失效:如果缓存项在...
1.写入一段时间后duration过期 2.写入后刷新缓存 cacheLoader 3.重新加载方法reload 3.1 需要判断key不为空,原值oldValue不为空 3.2 基于immediateFuture实现,创建一个ListenableFuture,这个future不能被取消或者超时, 并且isDone方法永远会返回值 3.3 调用localCache中实现,传入Callable<? extends V> valueLoader执行加载...

谷歌Guava的CacheLoader loadAll() vs reload()语义 、、 我真的很喜欢Guava11的CacheLoader的两点(感谢谷歌!)它们是loadAll()和reload(),前者允许我一次加载多个键,后者允许我在键“过时”但存在旧值时异步地重新加载它。(1, TimeUnit.MINUTES) new CacheLoader<Key, Graph>() { return getGraphFrom...

问番石榴CacheLoader有多个键，每个键都有自己的refreshAfterWriteEN显式清除 任何时候，你都可以显式地清除缓存项，而不是等到它被回收： 个别清除：Cache.invalidate(key) 批量清除：Cache.invalidateAll(keys) 清除所有缓存项：Cache.invalidateAll() 移除监听器 通过CacheBuilder.removalListener(...

But if it does, you would need a way to keep the cache of the styles you have added to the page. So that you can detect what has been removed & re-add to the page. When we see it technically, we use Webpack with style–loader to load & attach the css files in the style tag...
