非Springboot项目从config-server读取配置文件

cloud-config-context.properties

spring.application.name=XXapplicaiton

spring.cloud.config.url=http://config-server.com:1212/

#值可以是 空,local,以及远程配置文件的后缀
#空和local会读取本地配置文件，云端配置文件读取失败也会读取本地配置文件
spring.cloud.config.profile=

#spring.cloud.config.failFast=false #如果读取远程配置失败项目直接宕掉

#读取分支默认master
spring.cloud.config.label=master
