ACTIVEMQ and Spring Integration

ActiveMQ use of standard producer and consumer models
There are two kinds of data structures Queue, Topic
1 , queue queues, producers produce a message that can only be consumed by one consumer
2 , Topic topics, producers produce a message that can be consumed by multiple consumers

 

default TCP connection ActiveMQ Port 61616

import jar

2. Write the configuration producer
Configuring the activemq connection Factory

<!--ActiveMQ Connection Factory -    <!--A connectionfactory that can actually generate connection, provided by the corresponding JMS service vendor -    <!--If you are connected to a network: tcp://ip:61616; network not connected: tcp://localhost:61616 and username, password -    <amq:connectionfactoryID= "Amqconnectionfactory"Brokerurl= "tcp://localhost:61616"UserName= "Admin"Password= "Admin"  />    <!--Spring Caching Connection Factory -    <!--Spring is used to manage the connectionfactory of real ConnectionFactory -      <BeanID= "Mqconnectionfactory"class= "Org.springframework.jms.connection.CachingConnectionFactor <!--target connectionfactory corresponds to the real can generate JMS Connection ConnectionFactory--<property name= "targetconnectionfactory "ref= "Amqconnectionfactory"></ Property>        <!--Ditto, similarly -        <!--<constructor-arg ref= "Amqconnectionfactory"/> -        <!--Session Cache Count -        < Propertyname= "Sessioncachesize"value= "+" />    </Bean>         <!--Spring jmstemplate message producer start -    <!--define the queue type for jmstemplate -    <BeanID= "Jmsqueuetemplate"class= "Org.springframework.jms.core.JmsTemplate">        <!--This connectionfactory corresponds to the ConnectionFactory object that we have defined spring provides. -          <Constructor-argref= "Mqconnectionfactory" />        <!--Non-pub/sub model (publish/subscribe), which is the queue mode -        < Propertyname= "Pubsubdomain"value= "false" />    </Bean>    <!--defining the topic type of Jmstemplate -    <BeanID= "Jmstopictemplate"class= "Org.springframework.jms.core.JmsTemplate">         <!--This connectionfactory corresponds to the ConnectionFactory object that we have defined spring provides. -          <Constructor-argref= "Mqconnectionfactory" />        <!--Pub/sub Model (Publish/subscribe) -        < Propertyname= "Pubsubdomain"value= "true" />    </Bean><!--defining a Queue listener -<Jms:listener-containerDestination-type= "queue"Container-type= "Default"connection-factory= "ConnectionFactory"Acknowledge= "Auto"><!--The default registered bean name, which should be the first letter of the class name lowercase -<Jms:listenerDestination= "Bos_sms"ref= "Topicconsumer"/></Jms:listener-container>

The queue mode producer template, topic mode, is different from the injection class:

@Service Public classQueuesender {//Inject Jmstemplate@Autowired @Qualifier ("Jmsqueuetemplate")    Privatejmstemplate jmstemplate; Create a Send method, pass in the queue name, and a message to send Public voidSend (String queuename,FinalString message) {Jmstemplate.send (QueueName,NewMessagecreator () { PublicMessage CreateMessage (Session session)throwsjmsexception {returnsession.createtextmessage (message);    }        }); }}

Queue consumer Templates

@Service  Public class Implements MessageListener {    publicvoid  onMessage (Message message) {        = ( textmessage) message;         Try {            System.out                    . println ("Consumer queueconsumer Get Message:" + Textmessage.gettext ());         Catch (jmsexception e) {            e.printstacktrace ();     }}}

Producer Testing

@RunWith (Springjunit4classrunner.  Class= "Classpath:applicationcontext-mq.xml")publicclass  producertest {    @Autowired    private  queuesender Queuesender;    @Autowired    private  topicsender Topicsender;    @Test    publicvoid  testsendmessage () {        queuesender.send ("Spring_ Queue "," I am a producer ");}    }

Consumer Testing

@RunWith (Springjunit4classrunner.  Class= "Classpath:applicationcontext-mq-consumer.xml")publicclass  consumertest {    @Test    publicvoid  testconsumermessage () {        while (true) {            //  JUnit exits to prevent the process from dying         }     }}

Results the corresponding tester will output the corresponding message after running the producer test.
