can spring cloud config be used to set configuration properties without needing application restart

Question

can we use spring cloud config to change the configuration properties of one of the beans at runtime without having to restart the application i.e requiring context reloading.

I currently have a spring boot setup where any change to the application properties needs a restart of the application.

Answer 1

There are multiple options for refreshing the config properties without restart with spring cloud config. You can:

• call the refresh endpoint if you are using the spring actuators. Remember to consider the @RefreshScope for beans dependent on certain properties. See https://spring.io/guides/gs/centralized-configuration/
• use Spring Cloud Config Bus as a means of broadcasting config changes to all config clients. https://spring.io/projects/spring-cloud-bus#learn
