类名称：ZKPropertyStore

ZKPropertyStore介绍

[英]This class uses ZK for storing properties/configures. It provides update methods for updating properties, and listener methods for watching for changes in properties. TODO: Unify this and SharedResourceCache in security module.
[中]此类使用ZK存储属性/配置。它提供了更新属性的更新方法，以及监视属性更改的侦听器方法。TODO:在安全模块中统一此和SharedResourceCache。
