xuziyang opened a new issue, #581:
URL: https://github.com/apache/rocketmq-spring/issues/581

   声明一个抽象类EnhanceMessageHandler实现RocketMQListener接口
   
    abstract class EnhanceMessageHandler<T extends BaseMessage> implements RocketMQListener<T>{}
   
   声明一个类实现MchApplymentConsumer extends EnhanceMessageHandler<MchApplymentMessage>实现抽象类EnhanceMessageHandler
