SpringBoot使用ApplicationListener监听器

ApplicationEvent
–ApplicationContextEvent
|- ContextStartedEvent 应用关闭事件
|- ContextRefreshedEvent 应用刷新事件
|- ContextClosedEvent 应用开启事件
|- ContextStoppedEvent 应用停止事件
– 扩展了两个实现：
1、EmbeddedServletContainerInitializedEvent 内嵌Servlet容器初始化事件
2、ApplicationReadyEvent：Spring Application 启动完成事件
