SpringBoot学习(二)准备阶段~加载应用事件监听器

使用

@Order(Ordered.LOWEST_PRECEDENCE)
public class FirstApplicationListener implements ApplicationListener<ContextRefreshedEvent> {
    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        System.out.println("FirstApplicationListener--");
    }
}

# Application Listeners
org.springframework.context.ApplicationListener=\
com.example.config.listener.FirstApplicationListener,\
com.example.config.listener.SecondApplicationListener

运行监听器

监听方法	对应事件	监听阶段	备注
starting	ApplicationStartingEvent	应用刚启动
environmentPrepared	ApplicationEnvironmentPreparedEvent
contextPrepared	ApplicationContextInitializedEvent
contextLoaded	ApplicationPreparedEvent
started	ApplicationStartedEvent	Spring Bean已完成初始化
running	ApplicationReadyEvent
failed	ApplicationFailedEvent
