@Component
@Slf4j
public class ApolloConfigRefresher implements ApplicationContextAware {

    @Autowired
    private ApplicationContext applicationContext;

    @ApolloConfigChangeListener
    public void onChange(ConfigChangeEvent changeEvent) {
        // TODO 在此处监听发生改变的参数，若为连接池的参数需要重新加载链接池

        this.applicationContext.publishEvent(new EnvironmentChangeEvent(changeEvent.changedKeys()));
    }

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

}
