(11)springcloud配置中心--客户端

以hello-spring-cloud-web-admin-feign为例，

1.在pom.xml中增加依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
</dependency>

2.在application.yml原来配置删掉，加如下配置，

spring:
  cloud:
    config:
      uri: http://localhost:8888
      name: web-admin-feign
      label: master
      profile: dev

3.启动WebAdminFeignApplication项目，在启动日志中可以看到 端口号是8765

4.在hello-spring-cloud新建web-admin-feign-prod.yml

spring:
  application:
    name: hello-spring-cloud-web-admin-feign
  thymeleaf:
    cache: false
    mode: LEGACYHTML5
    encoding: UTF-8
    servlet:
      content-type: text/html

server:
  port: 8766

feign:
  hystrix:
    enabled: true

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

将配置文件上传到git

5.将第2步的application.yml配置文件中的profile:dev改成 profile：prod

spring:
  cloud:
    config:
      uri: http://localhost:8888
      name: web-admin-feign
      label: master
      profile: prod

再次启动WebAdminFeignApplication项目，在启动日志中可以看到 端口号是8766
