##### 二、SpringBoot2.x 微服务 #####

###### 2.1. 依赖引入 ######

###### 2.2. bootstrap.yaml配置 ######

spring:
      cloud:
        nacos:
          server-addr: 192.168.159.102:8848,192.168.159.103:8848,192.168.159.104:8848 # nacos集群服务地址
          config:
            file-extension: yaml # 表示支持扩展的文件名
      application:
        name: nacos-config # 表示当前微服务需要向配置中心索要nacos-config的配置
      profiles:
        active: prod # 表示我需要向配置中心索要生产环境的配置
    
    
    server:
      port: 9000
    
    
    management:
      endpoint:
      endpoints:
        web:
          exposure:
            include: '*'

###### 2.3. 测试类 ######

package com.gblfy.nacosconfig.controller;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.cloud.context.config.annotation.RefreshScope;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @RefreshScope
    public class NaocsController { 
    
    
        @Value("${nacosProd}")
        private String nacosProd;
    
        @GetMapping("/nacosProd")
        public String getNacosProd() { 
            return nacosProd;
        }
    }

##### 三、测试验证 #####

###### 3.1. 启动项目 ######
