上云服务类设计图

1：通过spring上下文，获取所有已注解@ActionAnnotation的实现类的BeanName，通过beanName反射获取实例化的实现类对象，通过实例化对象获取实现类注解名称，通过请求参数名称调用不同的实现类ApplicationContext applicationContext = SpringUtil.getApplicationContext();            String[] names = applicationContext.getBeanNamesForAnnotation(ActionAnnotation.class);            for (String name : names) {                AbstractDoorDataSyncHandler actionBean = (AbstractDoorDataSyncHandler) applicationContext.getBean(name);                Class clazz = actionBean.getClass();                @SuppressWarnings(\"unchecked\")                Annotation annotation = clazz.getAnnotation(ActionAnnotation.class);                ActionAnnotation actionAnnotation = (ActionAnnotation) annotation;                if (actionAnnotation.value().equals(beanName)) {                    actionBean.execute(obj);                }            }

实现类DoorAuthorityByBuildingEquipAddHandlerImpl

- needPersonDataSync:boolean- personDataSyncRebuilt()

策略模式

（接口）IDoorDataSyncHandler

+ execute()

接口：定义标准模板

实现类DoorAuthorityByBuildingEquipDelHandlerImpl

（抽象类）AbstractDoorDataSyncHandler

+ hook():boolean -勾子方法- extendMethod() -自定义扩展方法- execute() -实现接口- needPersonDataSync:boolean- personDataSyncRebuilt()

抽象类：可定义实现或未实现方法，主要为了重载重写复用

实现类：实现或重写抽象类或接口的方法，只有它能实例化，抽象类接口不行

实现类DoorAuthorityByPersonModifyHandlerImpl
