Notes on Dynamic Configuration Properties

Dynamic Configuration Properties in Spring Boot and Spring Cloud

TL;DR

  • Use @ConfigurationProperties and always get state from the bean.
  • The Environment can change at runtime and Spring Cloud does this for you using RefreshEvent.
  • Changes are propagated to beans in Spring Cloud in 2 ways (@ConfigurationProperties and @RefreshScope).
  • If you care about the state of @ConfigurationProperties being consistent on concurrent access, put it or the consumer @Bean in @RefreshScope.
