@RefreshScope not working - Spring Boot

Question

I am following the approach described here: https://github.com/jeroenbellen/blog-manage-and-reload-spring-properties, the only difference is that in my case, the properties

Answer 1

Try using @ConfigurationProperties instead. e.g.

@ConfigurationProperties(prefix="config")
public class CloudConfig {

    private Integer count;

    public Integer count() {
        return this.count;
    }

    public void setCount(Integer count) {
        this.count = count;
    }

}

The reference doc from spring cloud states:

@RefreshScope works (technically) on an @Configuration class, but it might lead to surprising behaviour: e.g. it does not mean that all the @Beans defined in that class are themselves @RefreshScope. Specifically, anything that depends on those beans cannot rely on them being updated when a refresh is initiated, unless it is itself in @RefreshScope (in which it will be rebuilt on a refresh and its dependencies re-injected, at which point they will be re-initialized from the refreshed @Configuration).

Answer 2

Anyone else facing this issue, please make sure the followings:

1. Your controller is annotated with @RefreshScope

2. Spring boot actuator is added into your dependency, as it is the module which actually provides these endpoints:

   org.springframework.boot spring-boot-starter-actuator

3. Refresh endpoint has been updated to:

   http://{ip_address}:{port}/actuator/refresh

4. Refresh endpoint isn't enabled by default. You have to enable it explicitly in the bootstrap.properties file by adding the following line:

   management.endpoints.web.exposure.include=*

I have enabled all the endpoints, while you can just enable the specific endpoints as well.
