Spring integrated Apache Qpid Simple Demo

Spring provides a SPRING-JMS module that integrates JMS into the spring container and provides a Jmstemplate template class to manipulate JMS, similar to the integrated JDBC database operation.

First, we create a new applicationcontext-qpid.xml to do the Qpid integration operation.

<?xml version= "1.0" encoding= "UTF-8"?><beans xmlns="Http://www.springframework.org/schema/beans"xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="Http://www.springframework.org/schema/beans http://www.springframework.org/ Schema/beans/spring-beans.xsd ">          <!--the JMS tool class provided by spring, which can send messages, receive, and so on    <bean id= "jmstemplate" class=" Org.springframework.jms.core.JmsTemplate ">          < property name="ConnectionFactory" ref="Jqpidconnectionfactory "/>      </Bean>    <!--linked to the Java broker Server -    <bean id= "jqpidconnectionfactory" class=" Org.apache.qpid.client.AMQConnectionFactory ">        <constructor-arg Index="0" value="Amqp://guest:[email protected ]/?brokerlist= ' tcp://localhost:5672 ' " />    </Bean>    <!--cache session, guaranteed single link--    <bean id= "jcachingconnectionfactory" class=" Org.springframework.jms.connection.CachingConnectionFactory ">        < property name= "targetconnectionfactory" ref=" Jqpidconnectionfactory " />        < property name="Sessioncachesize" value="1" />         < property name="Reconnectonexception" value="true" />    </Bean>    <!--subscription path --    <bean id= "jdestination" class=" Org.apache.qpid.client.AMQAnyDestination ">        <constructor-arg Index= "0" value="addr:message_queue; {create:always} " />    </Bean>    <!--receive event handlers --    <bean id="Jreceiver" class="Com.liuxg.qpid.receiver.MsgReceiver" />    <!--transaction processing --     <bean id= "TransactionManager" class=" Org.springframework.transaction.jta.JtaTransactionManager "/>    <!--default message listener --    <bean id= "devicestatuscontainer"class=" Org.springframework.jms.listener.DefaultMessageListenerContainer ">                < property name= "connectionfactory" ref=" Jcachingconnectionfactory " />        < property name= "exceptionlistener" ref=" Jcachingconnectionfactory " />        < property name="MessageListener" ref="Jreceiver" />        < property name="Destination" ref="jdestination" />         < property name= "TransactionManager" ref=" TransactionManager "/>    </Bean></Beans>

Then you need to add the applicationcontext-qpid.xml to the contextconfiglocation of Web. xml

<context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath*:META-INF/applicationContext*.xml</param-value></context-param>

Then, on the sending side, you can use the template class to send messages

@Service Public  class senderservice {    @AutowiredJmstemplate jmstemplate;@AutowiredAmqanydestination devicestatusdestination;/** * Send a message * /     Public void sendmsg() {Jmstemplate.send (devicestatusdestination,NewMessagecreator () {@Override             PublicMessageCreateMessage(Session session)throwsjmsexception {returnSession.createtextmessage ("Hello world!");    }        }); }}

When sent here, you can take advantage of the spring's message converter, which supports string and TextMessage, byte[] and bytesmesssage, as well as Java.util.Map and mapmessage conversions, such as the following

 Public voidSendwithconversion () {Map Map = NewHashMap ();Map.Put"Name","Mark");Map.Put"Age",New Integer( -)); Jmstemplate.Convertandsend ("Testqueue",Map,NewMessagepostprocessor () { PublicMessage postprocessmessage (Message message) throws JMSException {message.Setintproperty ("AccountID",1234); Message.Setjmscorrelationid ("123-00001");returnMessage }    });}

Finally on the receiving end, you can define a class implementation sessionawaremessagelistener or Devicestatusreceiver, where we implement Sessionawaremessagelistener

publicclass MsgReceiver implements SessionAwareMessageListener<Message>  {    @Override    publicvoid onMessage(Message message, Session session) throws JMSException {        JMSTextMessage xx = (JMSTextMessage) message;        String text = xx.getText();        System.out.println(text);    }}
