title: How to trigger a refresh event?

    <p>You can force a bean to refresh its configuration (that is, to pull updated values from the Config Server) by annotating the MessageRestController with the Spring Cloud Config @RefreshScope and then triggering a refresh event.</p>
  </blockquote>
  
  <p>How can we trigger this refresh event (for classes annotated with <code>@ConfigurationProperties</code> and <code>@RefreshScope</code>)? We don't want to use the spring actuator <code>/refresh</code> endpoint.
  What is necessary here, that the application fetches the config from configserver?</p>
