    <!--  配置生产者  -->
    <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">

            <bean class="org.apache.activemq.spring.ActiveMQConnectionFactory">

            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>
</beans>

队列生产者

@Service
public class SpringProduce {

    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-activemq.xml");
        SpringProduce springMQ_producer = applicationContext.getBean(SpringProduce.class);
        springMQ_producer.jmsTemplate.send(
                new MessageCreator() {
                    public Message createMessage(Session session) throws JMSException {
                        return session.createTextMessage("***Spring和ActiveMQ的整合case111.....");
                    }
                }
        );
        System.out.println("********send task over");
    }
}

队列消费者

@Service
public class SpringConsummer {

    @Autowired
    private JmsTemplate jmsTemplate;
    public static void main(String[] args) {
        ApplicationContext  ac = new ClassPathXmlApplicationContext("applicationContext.xml");
        Spring_MQConsummer  sm = (Spring_MQConsummer)ac.getBean("springMQConsummer");

        String s = (String) sm.jmsTemplate.receiveAndConvert();
        System.out.println(" *** 消费者消息"+s);
    }
}

配置消费者的监听类

<bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
		<property name="connectionFactory" ref="connectionFactory" />
		<property name="destination" ref="destinationQueue" />
		<property name="messageListener" ref="myMessageListener" />
</bean>

编写Listener的实现类

@Component
public class MyMessageListener implements MessageListener {
 
	@Override
	public void onMessage(Message message) {
		try {
			TextMessage textMessage = (TextMessage) message;
			//取消息内容
			String text = textMessage.getText();
			System.out.println(text);
		} catch (JMSException e) {
			e.printStackTrace();
		}
      }
}
