Microservice developers only concentrate on business logic, so Spring addresses this issues and comes with Feign Client, which works on the declarative principle. Group DEFAULT_GROUP spring.cloud.nacos.config.group . This behavior is controlled by the spring.cloud.kubernetes.config.paths property.

Then, on the next access to the bean, a new instance is created. A related discipline is that of building 12-factor Applications, in which development practices are aligned with delivery and operations goals for instance, by using declarative programming and management and Spring Boot applicationbean @ConfigurationPropertiesmailmail.properties Spring Cloud Distributed Configuration + Dubbo Configuration Center[6] Service registration and discovery. In Nacos Spring Cloud, the format of dataId is as follows: ${prefix}-${spring.profiles.active}.${file-extension} The value of prefix is the value of spring.application.name by default.
