簡介java

當咱們的業務系統愈來愈龐大複雜的時候，各類配置就會層出不羣。一旦配置修改了，那麼咱們就是必須修改後停服務，而後再上線，若是服務少，咱們能夠手動來操做，若是是成千上百的服務，若是是手動操做，確定就不合適宜了，而後SpringCloudConfig就出來了，就是咱們一般意義上的配置中心，把應用本來放在本地文件的配置抽取出來放在中心服務器，從而可以提供更好的管理、發佈能力。git

SpringCloudConfig分服務端和客戶端，服務端負責將git（svn或本地文件系統）中存儲的配置文件發佈成REST接口，客戶端能夠從服務端REST接口獲取配置。但客戶端並不能主動感知到配置的變化，從而主動去獲取新的配置，這須要每一個客戶端經過POST方法觸發各自的/refresh。web

SpringCloudBus經過一個輕量級消息代理鏈接分佈式系統的節點。這能夠用於廣播狀態更改（如配置更改）或其餘管理指令。SpringCloudBus提供了經過POST方法訪問的endpoint/bus/refresh，這個接口一般由git的webhook功能調用，用以通知各個SpringCloudConfig的客戶端去服務端更新配置，本節就講怎麼搭建一套自動刷新的spring cloud configspring

1、建立模塊docker

模塊結構以下：apache

2、maven聚合模塊microservice-config的pom.xml文件api
