### SpringCloud Config客户端配置与测试 ###

在本地D:\\44\\mySpringCloud\\microservicecloud-config路径下新建文件  
microservicecloud-config-eureka-client.yml

spring:
      profiles:
        active:
          - dev
    
    ---
    server:
      port: 8201
    spring:
      profiles: dev
      application:
        name: microservicecloud-config-client
    
    eureka:
      client:
        service-url:
          defaultZone: http://eureka-dev.com:7001/eureka/
    
    ---
    server:
      port: 8202
    spring:
      profiles: test
      application:
        name: microservicecloud-config-client
    
    eureka:
      client:
        service-url:
          defaultZone: http://eureka-dev.com:7001/eureka/

新建工程microservicecloud-config-eureka-client-7001：  
引入依赖：

                <artifactId>spring-boot-devtools</artifactId>
            </dependency>
        </dependencies>

bootstrap.yml：

spring:
      cloud:
        config:
          name: microservicecloud-config-client #需要从github上读取的资源名称，没有yml后缀名
          profile: dev  #本次访问的配置项
          label: master
          uri: http://config-3344.com:3344 #微服务启动后先去找3344服务，通过SpringCloudConfig获取GitHub的服务地址

application.yml

spring:
      application:
        name: microservicecloud-config-client

主启动类Config\_Git\_EurekaServerApplication：

@SpringBootApplication
    public class ConfigClient_3355_StartSpringCloudApp { 
        public static void main(String[] args) { 
            SpringApplication.run(ConfigClient_3355_StartSpringCloudApp.class, args);
        }
    }

测试用controller：

@RestController
    public class ConfigClientRest { 
    
        @Value("${spring.application.name}")
        private String applicationName;
    
        @Value("${eureka.client.service-url.defaultZone}")
        private String eurekaServers;
    
        @Value("${server.port}")
        private String port;
    
        @RequestMapping("/config")
        public String getConfig(){ 
            String str = "applicationName:" + applicationName + "\t" + "eurekaServers:" + eurekaServers + "\t" +
                    "port:" + port;
            System.out.println("*********************str:" + str);
            return "applicationName:" + applicationName + "\t" + "eurekaServers:" + eurekaServers + "\t" +
                    "port:" + port;
        }
    }

### 测试 ###

先启动microservicecloud-config-3344微服务，保证Config总配置是OK的

启动3355作为Client准备访问

bootstrap.yml里面的profile值是什么，决定从github上读取什么：

假如目前是 profile: dev，dev默认在github上对应的端口就是8201

*  http://client-config.com:8201/config  
    ![在这里插入图片描述][20200222220905489.png]

假如目前是 profile: test，test默认在github上对应的端口就是8202

*  http://client-config.com:8202/config

成功实现了客户端3355访问SpringCloud Config3344通过GitHub获取配置信息
