Class GenericsPayloadApplicationEvent<E>

java.lang.Object

java.util.EventObject

org.springframework.context.ApplicationEvent

org.springframework.context.PayloadApplicationEvent<E>

org.hswebframework.web.event.GenericsPayloadApplicationEvent<E>

All Implemented Interfaces:

Serializable, org.springframework.core.ResolvableTypeProvider

public class GenericsPayloadApplicationEvent<E>
extends org.springframework.context.PayloadApplicationEvent<E>

动态泛型事件,用于动态发布支持泛型的事件

     //相当于发布事件: EntityModifyEvent<UserEntity>
     eventPublisher
          .publishEvent(new GenericsPayloadApplicationEvent<>(this, new EntityModifyEvent<>(oldEntity, newEntity), UserEntity.class));

      //只监听相同泛型事件
      @EventListener
      public handleEvent(EntityModifyEvent<UserEntity> event){

      }
