ApplicationReadyEvent

ApplicationReadEvent

事件的来源是SpringApplication，事件发生时，所有的初始化步骤都已经完成。

用法

@Component
public class ApplicationReadyEventListener implements ApplicationListener<ApplicationReadyEvent>, Ordered {

    @Override
    public void onApplicationEvent(ApplicationReadyEvent applicationReadyEvent) {
        System.out.println("############started");
    }

    @Override
    public int getOrder() {
        return Ordered.LOWEST_PRECEDENCE;
    }
}

配合EventListener使用

@Component
class MyClassWithEventListeners {

    @EventListener({ApplicationReadyEvent.class})
    void contextRefreshedEvent() {
        System.out.println("event happened");
    }
}
