I have written a small test where I send a message to an existing ActiveMQ FORWARD queue. Unfortunately the message is sent to the queue but not received. Below you will find my two attempts to receive this message: through a MyMessageListener and through a MessageService. Both methods fail. Here is my test:
Map<Parameter, String> params = new HashMap<Parameter, String>();
params.put(key1, "601");
params.put(key2, "3000");
Map<String,String> headers = Collections.singletonMap("method-name","prepareHotDrink");
Message<?> msg = MessageBuilder.withPayload(params)
.copyHeaders(headers)
.build();
boolean i = inputChannel.send(msg);
This is my configuration file:
<bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="${jms.primary.server}"/>
</bean>
<!-- spring integration beans -->
<int-jms:channel id="inputChannel" queue-name="FORWARD"
connection-factory="connectionFactory" auto-startup="true">
</int-jms:channel>
<!-- Consumers -->
<int-jms:message-driven-channel-adapter
id="jmsIn"
container="messageListenerContainer"
channel="inputChannel"
extract-payload="true" />
<int:service-activator input-channel="inputChannel"
ref="messageService"
method="processMessage"/>
<bean id="messageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="connectionFactory" ref="connectionFactory"/>
<property name="destination" ref="requestQueue"/>
<property name="exposeListenerSession" value="false"/>
<property name="messageListener" ref="messageListener" />
</bean>
<bean id="messageListener" class="com.ucware.ucpo.forward.mess.MyMessageListener"/>
<bean id="messageService" class="com.ucware.ucpo.forward.jms.MessageService"/>
<bean id="requestQueue" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg name="name" value="FORWARD"/>
</bean>
It turned out ActiveMQ does not support channels. So I had to define a <jms:lintener-container>
and <jms:listener>
to be able to consume the messages. In addition I created a message producer that sends messages to the existing ActiveMQ queue.
<!-- RECEIVER -->
<bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory" p:brokerURL="${jms.primary.server}"/>
<bean id="messageListener" class="com.ucware.ucpo.forward.jms.ProductMessageListener"/>
<jms:listener-container connection-factory="connectionFactory" concurrency="2" acknowledge="auto">
<jms:listener destination="FORWARD" ref="messageListener" method="onMessage"/>
</jms:listener-container>
<!-- SENDER -->
<!-- A cached connection to wrap the ActiveMQ connection -->
<bean id="cachedConnectionFactory"
class="org.springframework.jms.connection.CachingConnectionFactory"
p:targetConnectionFactory-ref="connectionFactory"
p:sessionCacheSize="10" />
<!-- A destination in ActiveMQ -->
<bean id="destination"
class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="FORWARD" />
</bean>
<!-- A JmsTemplate instance that uses the cached connection and destination -->
<bean id="producerTemplate"
class="org.springframework.jms.core.JmsTemplate"
p:connectionFactory-ref="cachedConnectionFactory"
p:defaultDestination-ref="destination" />
</beans>
