版本一定要对（最好是使用

com.alibaba.cloud 的服务发现maven依赖 md5值不对可能导致nacos无限刷新naming Log日志

）

bootstrap.yml

  
spring:
  profiles:
      active: dev
---

server:
  port: 8081 
#showSql
logging:
  level:
    com:
      fwz:
        tproject : debug
spring:
  profiles:
    active: dev
  application:
    name: my-consumer
  cloud:
    nacos:
      config:
        file-extension: yml
        server-addr: 192.168.209.161:8848
      discovery:
        server-addr: 192.168.209.161:8848
---
spring:
  profiles: testing

高版本的nacos最好是指定开发环境，

my-consumer-dev.yml
不然我一直加载不到配置中心的数据。(原来是使用的springcloud的 nacos-config 依赖 换成alibaba的，不配置开发环境也能读到数据)
