Spring事件机制的使用

(一)、事件发布

1.启动SpringBoot项目

@SpringBootApplication
public class SpringEventApplication {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SpringEventApplication.class, args);
        OrderPo orderPo = new OrderPo();
        orderPo.setId(1);
        orderPo.setOrderId("1234");
        orderPo.setPayOrderId("p1234");
        ApplicationContextUtil.publishEvent(new PublisEvent(orderPo));
    }
}

2.创建工具类 

@Component
class ApplicationContextUtil implements ApplicationContextAware {
    private static final Logger logger = LoggerFactory.getLogger(ApplicationContextUtil.class);
    private static ApplicationContext APPLICATION_CONTEXT;
    /**
     * 设置spring上下文
     * @param applicationContext spring上下文
     * @throws BeansException
     */
    @Override
    public void setApplic
