Spring ApplicationListener监听器用法详解

@Repository
public class myListener implements ApplicationListener<ApplicationEvent>{
  @Override
  public void onApplicationEvent(ApplicationEvent event) {
    System.out.println("监听到的事件发布。。。。。。。。。。"+event.getClass());
    System.out.println("监听的内容。。。。。。。。。。"+event.toString());
  }
}

@Configuration
@Import(myListener.class)
public class MainListenerConfig {
}

public class ListenerTest {

  @Test
  public void test(){
    //创建容器
    AnnotationConfigApplicationContext applicationContext = new AnnotationConfigApplicationContext(MainListenerConfig.class);
    applicationContext.publishEvent(new ApplicationEvent("我发布的事件") {});
    applicationContext.close();
  }
}
