Nacos 服务器

nacos多环境配置

参考：https://www.cnblogs.com/didispace/p/10340685.html#undefined

修改配置文件

nacos.config-dev.properties:

sys.user.name=user-dev

nacos.config-test.properties:

sys.user.name=user-test

指定配置文件前缀

spring.cloud.nacos.config.prefix=nacos.config

添加启动参数

-Dspring.profiles.active=test

结果：

Nacos配置
