spring cloud alibaba实用攻略一 nacos配置

今天起总结一年来使用springcloudalibaba整套框架的心得与最佳实践,第一天先总结nacos配置最佳实践

一、 本机yml文件

bootstrap.yml

spring:
  profiles:
    active: dev
    可以多重环境配置,通过后缀来区分(dev/prod/test),
    如开发环境 命名为bootstrap-dev.yml

bootstrap-dev.yml

server:
 port: 5003 #指定服务运行的端口

spring:
 application:
   name: 服务名称

 cloud:
   nacos:
     discovery:
       namespace: 2b671868-e2a3-4ea0-8050-d6fc67706674
       server-addr: #注册中心ip+端口地址
       cluster-name: #服务集群名  ps:Nacos支持集群配置。集群是对指定微服务的一种虚拟分类
       service: ${spring.application.name}
       ip: ${spring.cloud.client.ip-address} #获取服务运行的ip
       port: ${server.port}

     config:
       namespace: 2b671868-e2a3-4ea0-8050-d6fc67706674
       server-addr: #配置中心ip+端口地址
       cluster-name:  #服务集群名
       ext-config[0]: #配置在配置中心的分类配置
         group: ${spring.profiles.active}
         data-id: datasource-${spring.profiles.active}.yml
       ext-config[1]:
         group: ${spring.profiles.active}
         data-id: jackson-${spring.profiles.active}.yml
       ext-config[2]:
         group: ${spring.profiles.active}
         data-id: mybatis-${spring.profiles.active}.yml
       ext-config[3]:
         group: ${spring.profiles.active}
         data-id: pagehelper-${spring.profiles.active}.yml
       ext-config[4]:
         group: ${spring.profiles.active}
         data-id: transport-${spring.profiles.active}.yml
         refresh: true
       ext-config[5]:
         group: ${spring.profiles.active}
         data-id: rocketmq-${spring.profiles.active}.yml
       ext-config[6]:
         group: ${spring.profiles.active}
         data-id: rocketmq-queue-${spring.profiles.active}.yml
       ext-config[7]:
         group: ${spring.profiles.active}
         data-id: feign-${spring.profiles.active}.yml
       ext-config[8]:
         group: ${spring.profiles.active}
         data-id: async-pool-${spring.profiles.active}.yml
       ext-config[9]:
         group: ${spring.profiles.active}
         data-id: redis-${spring.profiles.active}.yml

二、 常用nacos中心yml文件
