nacos配置中心将原来的配置读取到配置中心并且应用

将模块的所有配置放到配置中心里去

刚才说了那么多，我们可以将数值储存在配置中心，及时调用，那么我们是否可以将我们之前的配置放到配置中心里呢？

let‘s go!

我们当前的配值如下

spring:
  datasource:
    username: root
    password: root
    url: jdbc:mysql://192.168.58.131:3306/gulimall_sms
    driver-class-name: com.mysql.jdbc.Driver

  application:
    name: coupon
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
mybatis-plus:
  mapper-locations: classpath*:/mapper/**/*.xml
  global-config:
    db-config:
      id-type: auto
server:
  port: 7000

我们把它分成三个部分，分块管理

• 数据源

spring:
  datasource:
    url: jdbc:mysql://192.168.58.131:3306/gulimall_sms
    username: root
    password: root
    driver-class-name: com.mysql.jdbc.Driver

• mybatis-plus

mybatis-plus:
  mapper-locations: classpath*:/mapper/**/*.xml
  global-config:
    db-config:
      id-type: auto

• 其他

  spring:
    application:
      name: coupon
    cloud:
      nacos:
        discovery:
          server-addr: 127.0.0.1:8848
  server:
    port: 7000
  

我们开始在nacos的网址里写配置文件

• 别忘了创建时候加上yml

然后把这个放到bootstrap.properties和application.properties里

配置如下

spring.application.name=gulimall-coupon

spring.cloud.nacos.config.server-addr=127.0.0.1:8848

spring.cloud.nacos.config.namespace=b176a68a-6800-4648-833b-be10be8bab00

spring.cloud.nacos.config.group=dev

#1
#spring.cloud.nacos.config.ext-config[0].data-id=datasource.yml
#spring.cloud.nacos.config.ext-config[0].group=dev
#spring.cloud.nacos.config.ext-config[0].refresh=true
#spring.cloud.nacos.config.ext-config[1].data-id=mybatis-plus.yml
#spring.cloud.nacos.config.ext-config[1].group=dev
#spring.cloud.nacos.config.ext-config[1].refresh=true
#spring.cloud.nacos.config.ext-config[2].data-id=other.yml
#spring.cloud.nacos.config.ext-config[2].group=dev
#spring.cloud.nacos.config.ext-config[2].refresh=true



#2
spring.cloud.nacos.config.extension-configs[0].data-id=datasource.yml
spring.cloud.nacos.config.extension-configs[0].group=dev
spring.cloud.nacos.config.extension-configs[0].refresh=true

spring.cloud.nacos.config.extension-configs[1].data-id=mybatis-plus.yml
spring.cloud.nacos.config.extension-configs[1].group=dev
spring.cloud.nacos.config.extension-configs[1].refresh=true

spring.cloud.nacos.config.extension-configs[2].data-id=other.yml
spring.cloud.nacos.config.extension-configs[2].group=dev
spring.cloud.nacos.config.extension-configs[2].refresh=true

#上面两种，哪个好用用哪个
