RefreshScope bean are not getting updated on zookeeper config node values changed

Question

I my trying to implement the dynamic property refresh in spring-boot application. My config server here is zookeeper. But it seems, that there's some issue and without application re-start the values in the config files are not getting updated on runtime, whenever the zookeeper config node changes.

Bean (This needs to be refresh without application start whenever the zookeeper node -> prop.host gets updated):

@Data
@ConfigurationProperties(prefix = "prop")
@Configuration
@RefreshScope
@Slf4j
public class AppProperties {

    @NotEmpty
    private String host;

    @EventListener
    public void onRefreshScopeRefreshed(final RefreshScopeRefreshedEvent event) {
        log.info("Got refresh scope event HbaseProperties: {}", event);
    }
}
