I want to create a sender to generate message and the send it to all consumers. I am using topic, but something is wrong, if for example I have 3 consumers, only one takes the message in a random way. I don´t know what is wrog. Here is my server configuration
<amq:broker brokerName="granicaBroker" id="broker"
persistent="false" deleteAllMessagesOnStartup="true" enableStatistics="false"
useLoggingForShutdownErrors="true">
<amq:networkConnectors>
<amq:networkConnector name="linkToBrokerB"
uri="static:(tcp://xxx.xx.xxx.xx:61617)" networkTTL="3" duplex="true" />
</amq:networkConnectors>
<amq:transportConnectors>
<amq:transportConnector
uri="nio://xxx.xx.xxx.xx:61616?jms.useAsyncSend=true?jms.useCompression=true"
disableAsyncDispatch="false" />
</amq:transportConnectors>
</amq:broker>
<bean id="destination" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="JMS.TOPIC.NOTIFICATION" />
</bean>
<bean id="producerTemplate" class="org.springframework.jms.core.JmsTemplate"
p:connectionFactory-ref="connectionFactory"
p:defaultDestination-ref="destination" />
<bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"
p:brokerURL="nio://xxx.xx.xxx.xx:61616" />
And my producer class(just the part to send the message)
@Autowired
protected JmsTemplate jmsTemplate;
final String text = applicationEvent.getMsg();
jmsTemplate.send(new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
TextMessage message = session.createTextMessage(text);
return message;
}
});
My client context configuration:
p:brokerURL="nio://xxx.xx.xxx.xx:61616" />
<bean id="simpleMessageListener" class="notifications.NotifierControllerImpl"/>
<jms:listener-container container-type="default"
connection-factory="connectionFactory" acknowledge="auto">
<jms:listener destination="JMS.TOPIC.NOTIFICATION" ref="simpleMessageListener"
method="onMessage" />
</jms:listener-container>
And the java client class
public class NotifierControllerImpl implements MessageListener{
@Override
public void onMessage(Message message) {
try {
if (message instanceof TextMessage) {
TextMessage tm = (TextMessage)message;
System.out.println(tm.getText());
}
} catch (JMSException e) {
System.out.println(e.toString());
}
}
}
The destination needs to be a topic not a queue; use ActiveMQTopic
not ActiveMQQueue
.
