监听SpringBoot 服务启动成功事件并打印信息

监听SpringBoot 服务启动成功事件并打印信息

第一步：

定义一个组件实现ApplicationListener，并纳入到容器

@Component
@Slf4j
public class ServiceRunSuccessListener implements ApplicationListener {
    @Override
    public void onApplicationEvent(AvailabilityChangeEvent event) {
        log.info("===> boot 监听到事件：" + event);
        if (ReadinessState.ACCEPTING_TRAFFIC == event.getState()){
            log.info("===> boot 服务启动成功******");
        }
    }
}

第二步：启动服务
