disconf源码解读

tonygsw 2017-06-29

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。
