*项目启动触发

1.实现接口CommandLineRunner,配置注解@Component @Order(执行的顺序) 可添加多个事件

2.ApplicationRunner

3.ApplicationListener<ContextRefreshedEvent>

*项目停止触发

1.ApplicationListener<ContextClosedEvent>

demo:

/*** 应用项目启动-执行事件*/
@Component
@Order(1)
public class RocketConsumerListener implements CommandLineRunner {@Autowiredprivate MsgConsumer msgConsumer;/*** RocketMQ监听器** 启动消费者** @param args* @throws Exception*/@Overridepublic void run(String... args) throws Exception {System.out.println("RocketMQ消费者启动----");msgConsumer.init();}
}
