   Recently, I tryied solve this problem.
   1. My Main idea is use org.springframework.messaging.converter.SmartMessageConverter#fromMessage .This interface define a third parameter called "Object conversionHint".
   2. I switch the Definition of DefaultRocketMQListenerContainer#messageType to Type insteadof Class
   3. add a "private  MethodParameter onMessageParameter" member  to DefaultRocketMQListenerContainer and init it to indicate the onMessage parameter when afterPropertiesSet() 
   4.when doCovertMessage. if the messageType instanceof  ParameterizedType, then call fromMessage with the third parameter(methodParameter). The MappingJackson2MessageConverter can use it to deserialization the message.
