Question

Answer 1

Here is a working sample using Spring MDP/Activation Spec for websphere MQ

mdp-listener.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"      
    "http://www.springframework.org/dtd/spring-beans.dtd">


     <bean id="messageListener" class="com.rohid.samples.SpringMdp" />  

     <bean class="org.springframework.jms.listener.endpoint.JmsMessageEndpointManager">
         <property name="activationSpec">
           <bean class="com.ibm.mq.connector.inbound.ActivationSpecImpl">
               <property name="destinationType" value="javax.jms.Queue"/>
               <property name="destination" value="QUEUE1"/>
               <property name="hostName" value="A.B.C"/>
                   <property name="queueManager" value="QM_"/>
               <property name="port" value="1414"/>
               <property name="channel" value="SYSTEM.ADMIN.SVNNN"/>
               <property name="transportType" value="CLIENT"/>
               <property name="userName" value="abc"/>
               <property name="password" value="jabc"/>
            </bean>
          </property>
          <property name="messageListener" ref="messageListener"/>
          <property name="resourceAdapter" ref="myResourceAdapterBean"/>
    </bean>

    <bean id="myResourceAdapterBean" class ="org.springframework.jca.support.ResourceAdapterFactoryBean">
      <property name="resourceAdapter">
        <bean class="com.ibm.mq.connector.ResourceAdapterImpl">
          <property name="maxConnections" value="50"/>
        </bean>
      </property>
      <property name="workManager">
         <bean class="org.springframework.jca.work.SimpleTaskWorkManager"/>
      </property>
     </bean>
</beans>

web.xml

<context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>/WEB-INF/context/mdp-listener.xml</param-value>
 </context-param>

<listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

SpringMdp

   package com.rohid.samples;

  import javax.jms.JMSException;
  import javax.jms.Message;
  import javax.jms.MessageListener;
  import javax.jms.TextMessage;

  public class SpringMdp implements MessageListener {

     public void onMessage(Message message) {
        try {
           if(message instanceof TextMessage) {
              System.out.println(this + " : " + ((TextMessage) message).getText());
           }

        } catch (JMSException ex){
           throw new RuntimeException(ex);
        }
     }
  }

I just went through this myself. Start with the Spring Boot JMS Starter

Add a bean providing a MQQueueConnectionFactory

@Configuration
@EnableJms
public class MQConfiguration {
    @Bean
    public MQQueueConnectionFactory mqFactory()
    {
        MQQueueConnectionFactory    factory = null;
        try {
            factory     = new MQQueueConnectionFactory();
            factory.setHostName("localhost");
            factory.setPort(1414);
            factory.setQueueManager("QM.LOCAL");
            factory.setChannel("SYSTEM.DEF.SVRCONN");
            factory.setTransportType(JMSC.MQJMS_TP_CLIENT_MQ_TCPIP);
        }
        catch (JMSException e) {
            System.out.println(e);
        }
        return factory;
    }
}

Remove the dependency on org.apache.activemq / activemq-broker to make sure activemq doesn't sneak its way in.

Add dependencies on com.ibm.mqjms.jar, com.ibm.mq.jmqi.jar, dhbcore.jar

Run

Answer 3

These were written for WMQ V5.3 but mostly still apply. The things that have changed are more about the WMQ admin than the connectivity and config.

developerWorks: The Spring Series

Please be sure to include the versions of WMQ server and client on future posts because the details of the Java/JMS configuration differ. Also, be sure to use the version of the documentation that matches the version of WMQ client or server that you are working with.

Answer 4

You might also want to consider using Spring Integration on top of JMS; there's a sample here that uses ActiveMQ https://github.com/SpringSource/spring-integration-samples/tree/master/basic/jms - you would just need to change the JMS config to use MQ instead.

The sample reads from the console sends the message over JMS, read by a message-driven adapter, and written to the console.
