当我运行Spring Cloud Config Client项目config-client时，我发现了以下错误：

显然，配置服务器是错误的 . 但是，Spring Cloud Config Server在localhost：10000 /运行，项目的application.yml（config-client）在下面 . 为什么spring.cloud.config.uri不起作用？
application.yml [config-client]
server:
port: 10001
spring:
application:
name: config-client
cloud:
config:
label: master
profile: dev
uri: http://localhost:10000
