This is not specific to JHipster, this is how Spring Cloud Config works.
Unless you use Spring Cloud Bus, it's not automatic you must send a POST request to /management/refresh (JHipster configuration) in your microservice in order to force it to refresh itself and load the new value in. Also, you should check whether this endpoint is configured to require authentication as it is a rather sensitive endpoint.
