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，zkwather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，springmvcrestfulapi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:privateMap<String,DisconfCenterFile>confFileMap=newHashMap<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。
