RefreshScope
@RefreshScope is an annotation used in Spring Boot applications to indicate that a bean should be refreshed when there are changes to the external configuration.
When a bean is annotated with @RefreshScope, Spring Boot will create a proxy for that bean and refresh the proxy whenever there are changes to the configuration properties. This allows the bean to pick up the updated values without requiring a restart of the application.
The @RefreshScope annotation can be used on any Spring bean, including controllers, services, and components. By using this annotation, you can ensure that your beans always have access to the most up-to-date configuration values.
To enable automatic refreshing of beans annotated with @RefreshScope, you need to include the spring-cloud-context dependency in your project and enable the Actuator module. The Actuator module provides an endpoint (/refresh) that can be used to trigger the refreshing of beans.
Overall, @RefreshScope is a useful annotation in Spring Boot applications that allows beans to be refreshed automatically when there are changes to the external configuration
