Java Message Service, 2nd Edition

Sending Messages

There are two ways to send a message when using Spring: you can create a standard JMS Message object (e.g., TextMessage) and send that message using the send method on the JmsTemplate, or you can create a Java object (e.g., String) and send it using the convertAndSend method without having to first create a JMS Message object. Both of these techniques can use either a default destination (specified in the defaultDestination or defaultDestinationName properties on the JmsTemplate) or a specific destination specified directly in the send or convertAndSend methods.

When specifying a default destination on the JmsTemplate, you can use either the defaultDestination property or the defaultDestinationName property. The defaultDestination property takes a reference to a JMS destination. This can be a javax.jms.Destination, javax.jms.Queue, javax.jms.Topic, or a reference bean created from one of the specific destination classes provided by a JMS provider (for example, com.ibm.mq.jms.MQQueue). The defaultDestinationName property takes a String argument containing the JNDI name of the queue or topic. Note that when using the defaultDestinationName, you must also have a destinationResolver bean defined so the JNDI name can be resolved.

In the following two subsections, we will show how to use the send and convertAndSend methods using a default destination. In the third subsection, we will show how to specify a JMS destination in the send methods using either a JNDI name or a ...
