SpringCloud -config 配置中心

配置中心的配置：gitee上

application.yml

spring:
  profiles:
    active:  dev

spring:
  profiles: dev
  application:
    name: springcloud-config-dev
    
    
---
spring:
  profiles: prod
  application:
    name: springcloud-config-prod

config-client.yml

spring:
  profiles:
    active: dev

server:
  port: 8989

spring:
  profiles: dev
  application:
    name: springcloud-configclient-dev

eureka:
  client:
    service-url:    
      defaultZone: http://eureka02.server.com:7002/eureka/,http://eureka03.server.com:7003/eureka/,http://eureka01.server.com:7001/eureka/

eureka:
  client:
    service-url:    
      defaultZone: http://eureka02.server.com:7002/eureka/,http://eureka03.server.com:7003/eureka/,http://eureka01.server.com:7001/eureka/ 

SpringCloud -Config 它是C/S架构

服务端模块：SpringCloud_Config

配置文件关联远程的配置中心的配置

server:
  port: 3344
spring:
  application:
    name: springcloud-config-server
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/gtnotgod/springcloud-netflix-config.git

怎么读取远程配置：

#  http://localhost:3344/application-prod.yml
#  HTTP服务具有以下格式的资源：
#
#  /{application}/{profile}[/{label}]
#  /{application}-{profile}.yml
#  /{label}/{application}-{profile}.yml
#  /{application}-{profile}.properties
#  /{label}/{application}-{profile}.properties

开启配置中心

@SpringBootApplication
@EnableConfigServer //开启配置中心
public class SpringCloudConfig {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudConfig.class, args);
    }
}

访问：http://localhost:3344/application-dev.yml

客户端：--访问服务端 ---访问配置中心

客户端模块：Springcloud_Config_Client
