Review comment:
Thanks for your solution，this is actually can made the code be cleaner.I
think I ignore the producer default `sendMsgTimeOut` value in broker
config.This is a lesson for me . I learn how about pull a request and remember
the param which producer sendTimeOut.Thanks for your kind of giving me an
opportunity that I can really feeling join with RocketMq-Spring.
End of all.Should I will change my branch code as your cleaner code and pull
request?Or you already finish it.
