依次啟動 eureka-server config-server config-bus

訪問http://localhost:8001/

訪問 http://localhost:7003/from

git-dev-1.0 QAQ

修改程式碼倉庫的檔案內容 from=git-dev-1.0 hasagei!

先post一下 http://localhost:7003/actuator/bus-refresh

然後先前是G版本的 無論怎麼post都不行，後面查資料才知道Greenwich.M1版本的bus匯流排/actuactor/bus-refresh時發生問題。

所以改成了H版本 一下就成功了。

再訪問 http://localhost:7003/from 出現

git-dev-1.0 hasagei!

spring cloud config+bus配置中心，出現Dispatcher has no subscribers錯誤
