@ApolloConfigChangeListener 无效

[Sam0913]

`
@slf4j
@component
public class ApolloConfig implements ApplicationContextAware {

private ApplicationContext applicationContext;

@ApolloConfigChangeListener
public void onChange(ConfigChangeEvent changeEvent){
    log.info("apollo conf update starts!");
    // 更新configrationProperties
    applicationContext.publishEvent(new EnvironmentChangeEvent(changeEvent.changedKeys()));
    log.info("apollo conf update success!");
}

@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
    this.applicationContext = applicationContext.getParent();
}

}
`

这边能取到最新配置，但是使用@ConfigurationProperties(prefix = "spring.datasource")的配置还是久的值

Spring Boot version?

run

mvn dependency:tree > tree.log

get it.

@RefreshScope 如果使用这种方式虽然可以动态更新了，但是会导致eureka 注册当前服务进行先down 在 up操作。

You could refresh the specific bean with the bean name, e.g.
https:/apolloconfig/apollo/blob/96ee53a2c98da763ef0e7557af33c03a8d2ae297/apollo-demo/src/main/java/com/ctrip/framework/apollo/demo/spring/springBootDemo/refresh/SpringBootApolloRefreshConfig.java#L47-L53

BTW, I verified EnvironmentChangeEvent also works in spring boot 2.4.12 and spring cloud 2020.0.4. If it doesn't work for your scenario, please take a look at your ConfigurationProperties setup and make sure it is not annotated with RefreshScope.

恩，是我只写取application错误了，请问@RefreshScope 会导致服务重启的问题您遇过吗？

@Sam0913 You need to refresh a specific bean instead of refresh all. But I think even refresh all will only trigger eureka to unregister and register itself but won't restart the service.
