#|spring-cloud-config使用 #|spring-cloud

实现功能可通过git仓库或本地文件进行配置支持手动更新配置
本文代码 https://github.com/tothis/spring-cloud-learn/tree/master/config

查看客户端配置

http://localhost:8082/config-client/dev http://localhost:8082/config-client-dev.json http://localhost:8082/config-client-dev.yaml http://localhost:8082/config-client-dev.yml http://localhost:8082/config-client-dev.properties

刷新配置

curl -X POST http://localhost:8082/actuator/bus-refresh

properties yml 相同的键显示properties的值
