Spring的自定义事件监听

实现Spring的事件监听有两种方法：继承EventListener和@EventListener注解

1.自定义事件

public class MyEvent extends ApplicationEvent {

	private String name;

	public MyEvent(Object source, String name) {
		super(source);
		this.name = name;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
}

2.定义监听器

  2.1 注解

@Component
public class MyListener {

	@EventListener
	public void handleDemoEvent(MyEvent myEvent) {
		System.out.println("发短信给：" + myEvent.getName());
	}
}

  2.2 实现ApplicationListener接口

@Component
public class MyListen2 implements ApplicationListener {
	@Override
	public void onApplicationEvent(MyEvent myEvent) {
		System.out.println("发送短信给：" + myEvent.getName());
	}
}

3.发布事件

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class PiWebApplicationTests {

    @Autowired
    private ApplicationContext applicationContext;

    @Test
    public void testEvent() {
        applicationContext.publishEvent(new MyEvent(this, "张三"));
    }

}
