Spring Integration provides two adapters for accepting JMS messages: JmsPollingSourceAdapter and JmsMessageDrivenSourceAdapter. The former uses Spring's JmsTemplate to receive based on a polling period. The latter configures and delegates to an instance of Spring's DefaultMessageListenerContainer.

The JmsPollingSourceAdapter requires a reference to either a single JmsTemplate instance or both ConnectionFactory and Destination (a 'destinationName' can be provided in place of the 'destination' reference). The JmsPollingSourceAdapter also requires a 'channel' property that should be a reference to a MessageChannel instance. The adapter accepts additional properties such as: period, initialDelay, maxMessagesPerTask, and sendTimeout. The following example defines a JMS source adapter that polls every 5 seconds and then sends to the "exampleChannel":

<bean class="org.springframework.integration.adapter.jms.JmsPollingSourceAdapter">
    <constructor-arg ref="jmsTemplate"/>
    <property name="channel" ref="exampleChannel"/>
    <property name="period" value="5000"/>
</bean>

In most cases, Spring Integration's message-driven JMS adapter is more appropriate since it delegates to a MessageListener container and supports dynamically adjusting concurrent consumers. The JmsMessageDrivenSourceAdapter requires references to a MessageChannel, a ConnectionFactory, and a Destination (or 'destinationName'). The following example defines a JMS message-driven source adapter that receives from the JMS queue called "exampleQueue" and then sends to the Spring Integration channel named "exampleChannel":

<bean class="org.springframework.integration.adapter.jms.JmsMessageDrivenSourceAdapter">
    <property name="connectionFactory" ref="connectionFactory"/>
    <property name="destinationName" value="exampleQueue"/>
    <property name="channel" ref="exampleChannel"/>
</bean>

For both source adapter types, Spring's MessageConverter strategy is used to convert the JMS message into a plain Java object, and then Spring Integration's MessageMapper strategy is used to convert from the plain object to a Message.

The JmsTargetAdapter is a MessageHandler implementation that is capable of mapping Spring Integration Messages to JMS messages and then sending to a JMS destination. It requires either a 'jmsTemplate' reference or both 'connectionFactory' and 'destination' references (again, the 'destinationName' may be provided in place of the 'destination). In the section called “Configuring Channel Adapters”, you will see how to configure a JMS target adapter with Spring Integration's namespace support.
