Spring Cloud Config分布式配置中心的使用和遇到的坑

1、springboot: Finchley.RC2 Cannot load environment] with root cause

**解决方法：**是Finchley.RC2版本问题，改成Finchley.RC1即可。

##2、SpringCloud Config配置远程git仓库获取配置，一直报Cannot clone or checkout repository

解决方法：

将配置，注意uri地址

spring.cloud.config.label=master
spring.cloud.config.server.git.uri=https://github.com/xxx/SpringCloud.git
spring.cloud.config.server.git.search-paths=application

改成这种格式

spring.cloud.config.label=master
[email protected]:xxx/SpringCloud.git
spring.cloud.config.server.git.search-paths=application
