在Spring中使用JMS

Spring对JMS进行封装，使用起来更简单。以下给出范例代码供参考！

 

在Spring中可以用JmsTemplate对象来发送、接收消息。

 

1、连接工厂

<bean id="smsConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
    <property name="connectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL" value="tcp://localhost:61616"/>
        </bean>
    </property>
</bean>

<bean id="smsConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop"> 

	<property name="connectionFactory"> 

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

			<property name="brokerURL" value="tcp://localhost:61616"/>

		</bean> 

	</property> 

</bean>

    在非web/EJB容器中使用pool时，要手动stop，spring不会为你执行destroy-method的方法。

    如果使用了PooledConnectionFactory要把 apache-activemq-5.3.0\lib\optional\activemq-pool-5.3.0.jar 加到 classpath中。

 

2、目的地

<bean id="smsDestination" class="org.apache.activemq.command.ActiveMQQueue">
    <constructor-arg value="sms_queue"/>
</bean>

<bean id="smsDestination" class="org.apache.activemq.command.ActiveMQQueue"> 

	<constructor-arg value="sms_queue"/> 

</bean>

 

3、JmsTemplate

<bean id="smsJmsTemplate" class="org.springframework.jms.core.JmsTemplate">
    <property name="connectionFactory" ref="smsConnectionFactory"/>
    <property name="defaultDestination" ref="smsDestination"/>
</bean>

<bean id="smsJmsTemplate" class="org.springframework.jms.core.JmsTemplate"> 

	<property name="connectionFactory" ref="smsConnectionFactory"/> 

	<property name="defaultDestination" ref="smsDestination"/> 

</bean>

    用JmsTemplate时不用自己提交session.commit()。

 

   用JmsTemplate发送消息：

jmsTemplate.send(new MessageCreator() {
    @Override
    public Message createMessage(Session session) throws JMSException {
        MapMessage map = session.createMapMessage();
        map.setString("mobile", mobile);
        map.setString("content", content);
        return map;
    }
});

jmsTemplate.send(new MessageCreator() {

	@Override

	public Message createMessage(Session session) throws JMSException {

		MapMessage map = session.createMapMessage();

		map.setString("mobile", mobile);

		map.setString("content", content);

		return map;

	}

});

   

4、消息监听器

<bean id="smsMessageListener" class="com.travelsky.bravo.components.communication.sms.SmsMessageListener" />

<bean id="smsMessageListener" class="com.travelsky.bravo.components.communication.sms.SmsMessageListener" />

 

   消息监听器类源码：

    消息监听器类必须实现MessageListener接口类

public class SmsMessageListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        try{
            if(message!=null && message instanceof MapMessage){
                MapMessage map = (MapMessage) message;
                String mobile = map.getString("mobile");
                String content = map.getString("content");

                send(mobile, content);
            }
        }catch(JMSException ex){
            logger.error(ex);
        }
    }
}

public class SmsMessageListener implements MessageListener {

	@Override

	public void onMessage(Message message) {

		try{

			if(message!=null && message instanceof MapMessage){

				MapMessage map = (MapMessage) message;

				String mobile = map.getString("mobile");

				String content = map.getString("content");

				

				send(mobile, content);

			}

		}catch(JMSException ex){

			logger.error(ex);

		}

	}

}

 

5、任务执行器

<bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor"/>

<bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor"/>

 

6、消息监听器容器

<bean id="smsListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer" lazy-init="false">
    <property name="connectionFactory" ref="smsConnectionFactory" />
    <property name="destination" ref="smsDestination" />
    <property name="messageListener" ref="smsMessageListener" />
    <property name="taskExecutor" ref="taskExecutor"/>

    <property name="sessionTransacted" value="true"/>

    <!-- 应该只是在Destination为Queue的时候才使用多个MessageConsumer -->
    <property name="concurrentConsumers" value="1"/>
    <property name="maxConcurrentConsumers" value="50" />

    <property name="idleTaskExecutionLimit" value="2" />
    <property name="receiveTimeout" value="10000" />

    <!-- 0:CACHE_NONE,1:CACHE_CONNECTION,2:CACHE_SESSION,3:CACHE_CONSUMER,4:CACHE_AUTO -->
    <property name="cacheLevel" value="0"/>
</bean>

<bean id="smsListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer" lazy-init="false"> 

	<property name="connectionFactory" ref="smsConnectionFactory" /> 

	<property name="destination" ref="smsDestination" /> 

	<property name="messageListener" ref="smsMessageListener" />

	<property name="taskExecutor" ref="taskExecutor"/>

	

	<property name="sessionTransacted" value="true"/>	



	<!-- 应该只是在Destination为Queue的时候才使用多个MessageConsumer -->

	<property name="concurrentConsumers" value="1"/> 

	<property name="maxConcurrentConsumers" value="50" /> 

	

	<property name="idleTaskExecutionLimit" value="2" />

	<property name="receiveTimeout" value="10000" /> 

	

	<!-- 0:CACHE_NONE,1:CACHE_CONNECTION,2:CACHE_SESSION,3:CACHE_CONSUMER,4:CACHE_AUTO -->  

	<property name="cacheLevel" value="0"/> 

</bean>

    lazy-init参数值必须设置为false，否则监听不起作用。
