SpringCloud Alibaba——Nacos configuration center configuration priority

1. Nacos configuration center configuration priority ( priority increases from low to high from 1.1 to 1.5 )

1.1. Application name + environment variable name. File extension

• grammar:

  ${
        
        application.name}-${
        
        profile}.${
        
        file-extension}
  

• Example
  nacos-config-prod.yaml

1.2. Application name. File extension

• grammar:

  ${
        
        application.name}.${
        
        file-extension}
  

• Example
  nacos-config.yaml

1.3. Application name

• grammar:

  ${
        
        application.name}
  

• Example
  nacos-config

1.4. Extended configuration file

• grammar:

  extensionConfigs
  

• example

  #支持一个应用有多个DataId配置，mybatis.yaml datasource.yaml
  spring.cloud.nacos.config.extension-configs[o].data-id=datasource.yaml
  spring.cloud.nacos.config.extension-configs[o].group=DEFAULT_GROUP
  spring.cloud.nacos.config.extension-configs[o].refresh=true
  

1.5. Public configuration of multiple microservices

• grammar:

  sharedConfigs
  

• example

  #自定义Data Id的配置 共享配置 (sharedcenfigs)
  spring.cloud.nacos.config.shared-configs[o].data-id= common.yaml
  #可以不配置，使用默认
  spring.cloud.nacos.config.shared-configs[o].group=DEFAULT_GROUP
  #这里需要设置为true，动态可以刷新，默认为false
  spring.cloud.nacos.config.shared-configs[o].refresh=true
