@EntityListeners({KpiOrderCounter.class})

/*** 订单管理考核** @author sula*/
@Slf4j
@Data
@Component
public class KpiOrderCounter implements ApplicationContextAware {private static ApplicationContext applicationContext;private static FrameFeign frameFeign;private static  MpBusiOrderService mpBusiOrderService;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {KpiOrderCounter.applicationContext = applicationContext;KpiOrderCounter.mpBusiOrderService = applicationContext.getBean(MpBusiOrderService.class);KpiOrderCounter.frameFeign = applicationContext.getBean(FrameFeign.class);}@PrePersistpublic void prePersist(MpBusiOrder entity) {System.out.println("进行insert之前");}@PostPersistpublic void postPersist(MpBusiOrder entity) {System.out.println("进行insert之后");}@PreUpdatepublic void preUpdate(MpBusiOrder entity) {System.out.println("进行update之前");}@PostUpdatepublic void postUpdate(MpBusiOrder entity) {System.out.println("进行update之后");}}
