1. 事件类型
A. ContextRefreshedEvent —— ApplicationContext容器初始化或者刷新时触发该事件；
B. ContextStartedEvent —— 当使用ConfigurableApplicationContext接口的start()方法启动ApplicationContext容器时触发该事件；
C. ContextClosedEvent —— 当使用ConfigurableApplicationContext接口的close()方法关闭ApplicationContext容器时触发该事件；
D. ContextStopedEvent —— 当使用ConfigurableApplicationContext接口的stop()方法停止ApplicationContext容器时触发该事件。
2. 举例
package com.ruhuanxingyun; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import com.nsac.business.listener.ApplicationStartup; @SpringBootApplication public class SpApp { public static void main(String[] args) { SpringApplication springApplication = new SpringApplication(SpApp.class); springApplication.addListeners(new ApplicationStartup()); springApplication.run(args); } }
package com.nsac.ruhuanxingyun; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationListener; import org.springframework.context.event.ContextRefreshedEvent; public class ApplicationStartup implements ApplicationListener<ContextRefreshedEvent> { @Override public void onApplicationEvent(ContextRefreshedEvent event) { ApplicationContext ac = event.getApplicationContext(); StepExecutor StepExecutor = new StepExecutor(ac.getEnvironment().getProperty("project-id"), ac.getBean("businessSingleJedisPool",redis.clients.jedis.JedisPool.class), ac.getBean("redisCluster", redis.clients.jedis.JedisCluster.class)); Thread thread = new Thread(StepExecutor); thread.start(); } }
