nacos实现配置的动态变更方式

2026-06-12 08:53:03 作者：大佬腿好粗

这段描述主要介绍了如何通过Spring Cloud Alibaba Nacos Config引入依赖实现配置动态变更,重点在于配置Nacos命名空间及YMLML文件动态引用,最后通过启动项目自动加载Nacos中的配置文件

pom引入依赖

spring-cloud-starter-alibaba-nacos-config用于配置的动态变更

nacos管理台新建命名空间

bootstrap.yml配置

动态引用ddw命名空间下的DEFAULT_GROUP组的application.yml配置文件
动态引用ddw命名空间下的DEFAULT_GROUP组的application.yml配置文件@artifactId@组下的application-dev.yml配置文件

spring:
  application:
      name: @artifactId@
  profiles:
    active: @environment@
  cloud:
    nacos:
      discovery:
        namespace: ddw
      config:
        namespace: ddw
        group: @artifactId@
        file-extension: yml
        shared-configs:
          - data-id: application.${spring.cloud.nacos.config.file-extension}
            group: DEFAULT_GROUP
            refresh: true
          - data-id: application-${spring.profiles.active}.${spring.cloud.nacos.config.file-extension}
            group: @artifactId@
            refresh: true

bootstrap-dev.yml配置

指定nacos服务的地址

spring:
  cloud:
    nacos:
      server-addr: 127.0.0.1:8848

nacos管理台配置文件

启动项目，就会自动加载nacos中的配置文件

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
