Spring Set MessageProducer's deliveryMode after create Producer

I find out that the producer does not have the same deliveryMode that the JmsTemplate has.

Thanks for the PR. The Javadoc of setDeliveryMode states that it is only used with QoS:

Since a default value may be defined administratively, this is only used when "isExplicitQosEnabled" equals "true".

createProducer being used internally by JmsTemplate, that hopefully explains why it isn't set on the producer. If you want to use JmsTemplate and override the QoS attribute, you'll need to invoke setExplicitQosEnabled(true) as well.
