表结构设计：

iot_config_center
id,parent_id（-1为根目录）,key,value,status (-1删除,0失效,1有效),app_id,created,update,update_uid

iot_app_config 应用表
id,app_code，name,status (-1删除,0失效,1有效),created,update,update_uid

配置平台接口
configCreate(parent_id,key，value)
configUpdate(id,value)
configStatusUpdate(id,status)

微服务创建
appConfigCreate(value)

Redis
config_appId_key value
后台管理系统保存回溯覆盖

内存缓存(单实例)
map(app_id, hashmap(key, Object))
Object:value,childKey_list

微服务
getValue(app_code(业务id),key)
Http

应用场景：低数据量高频变动高性能配置化需求
