disconf源码解读

disconf 主要分为三个项目:
    1-disconf.core   主要是提供助手类http的resful 重试等等，zk wather封装，加强了重试机制，做的东西很薄。
   2-disconf.client  强依赖 spring,提供了 扫包，自定义annotation的解析装配，切面逻辑处理aspectj，获取远端配置，并落地  做的东西比较多  依赖也很多。
   3-disconf.web   是后台管理的web应用，spring mvc restful  api实现，前后端分离的开发模式，提供登录，后台管理的功能，业务的东西多一点，可能因为开源的原因，好多有些小功能上的bug，并没有提供权限管理的功能。


问题:private Map<String, DisconfCenterFile> confFileMap = new HashMap<String, DisconfCenterFile>();

内部实现是一个hashMap

DISCCONF本身代码写的很糟糕，使用过程中经常的发生问题，不推荐使用。
