Deliverymode__java of "JAVA.JMS" JMS messages

DeliveryMode indicates the transmission mode of the message:

deliverymode.non_persistent --Indicates that the message does not exist until the message is consumed, if the JMS Providers (such as active MQ) is down, after the reboot. deliverymode.persistent --Indicates that the message still exists if the JMS Providers (such as active MQ) is down before the message is consumed.

Can be set by producer,

Messageproducer.setdeliverymode ()

Although the method for setting the delivery mode in the header is provided in the message interface, this value is overwritten by the delivery mode set by producer when it is sent .
