springBoot事件监听流程
1 自定义事件,一般是继承ApplicationEvent抽象类
/**
* 定义事件
**/
public class MyApplicationEvent extends ApplicationEvent {
private static final long serialVersionUID = 787751246882182041L;
public MyApplicationEvent(Object source) {
super(source);
}
}
2 自定义监听器,一般是实现ApplicationListen接口
/**
* 自定义监听器
**/
@Component
public class MyApplicationListener implements ApplicationListener<MyApplicationEvent>{
@Override
public void onApplicationEvent(MyApplicationEvent event) {
System.out.println("接收事件:"+event.getClass());
}
}
3 发布事件
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class App {
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(App.class, args);
//发布事件
context.publishEvent(new MyApplicationEvent(new Object()));
context.close();
}
}
这就是SpringBoot中最简单的一个事件监听.
