spring事件消息

数据对象：

@Data
@Builder
public class SelfEvent {
    /**
     * 消息类型
     */
    private SelfEventTypeEnum selfEventTypeEnum;

    /**
     * 消息体
     */
    private Object body;

}

事件发布工具类：

@Component
public class SelfEventService {

    private static ApplicationContext context;

    public SelfEventService(ApplicationContext applicationContext) {
        this.context = applicationContext;
    }

    public static void publishSelfEvent(SelfEvent selfEvent) {
        context.publishEvent(selfEvent);
    }
}

事件处理类：

@Component
public class SelfEventListener {
    private final Logger log = LoggerFactory.getLogger(SelfEventListener.class);

    @EventListener
    @Async
    public void handleOrderEvent(SelfEvent event) {
        if (event == null) {
            return;
        }
        switch (event.getSelfEventTypeEnum()) {
            case ***:
                handle....;
                break;
            default:
                log.info("不支持的事件类型");

        }
    }
}
