spring集成ActiveMQ, 消息提供者

1.spring集成ActiveMQ，依赖包

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-jms</artifactId>
	<version>4.2.6.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.apache.activemq</groupId>
	<artifactId>activemq-client</artifactId>
	<version>5.13.3</version>
</dependency>
<dependency>
	<groupId>org.apache.activemq</groupId>
	<artifactId>activemq-spring</artifactId>
	<version>5.13.3</version>
</dependency>

2.配置spring文件,主要配置ConnectionFactory,和ActiveMQDestination，JSMTemplate

<!-- ActiveMQConnectionFactory -->
<bean id="activeMQConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
	<constructor-arg index="0" value="tcp://127.0.0.1:61616"/>
	<property name="trustedPackages">
		<list>
			<value>com.lance.mq</value>
			<value>java.util</value>
		</list>
	</property>
</bean>

<!-- 创建pooledConnectionFactory连接池, JmsTemlate每次发送消息都重新打开一个Connection -->
<bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory">
	<property name="connectionFactory" ref="activeMQConnectionFactory"/>
	<property name="maxConnections" value="5"/>
</bean>


<!-- CachingConnectionFactory 
<bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
	<constructor-arg index="0" ref="activeMQConnectionFactory"/>
</bean>
-->

<!-- jmsTemplate -->
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
	 <property name="connectionFactory" ref="pooledConnectionFactory"/>
	 <property name="messageConverter">
		<bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
	 </property>
</bean>

<!-- ActiveMQQueue -->
<bean id="activeMQQueue" class="org.apache.activemq.command.ActiveMQQueue">
	<constructor-arg index="0" value="queue"/>
</bean>

3.消息发送

/**
 * 发送Text消息队列
 * @param message
 */
public void sendTextQueueMessage(final String message) {
	jmsTemplate.send(activeMQQueue, new MessageCreator(){
		@Override
		public Message createMessage(Session session) throws JMSException {
			return session.createTextMessage(message);
		}
	});
}

/**
 * 发送消息并处理消息返回值
 * @param message
 * @throws JMSException 
 */
public String sendTextQueueMessageAndReceive(final String message) throws JMSException {
	Message replyMessage = jmsTemplate.sendAndReceive(activeMQQueue, new MessageCreator(){
		@Override
		public Message createMessage(Session session) throws JMSException {
			return session.createTextMessage(message);
		}
	});
	
	log.info("sendTextAndReceive: {}", JSON.toJSONString(replyMessage));
	TextMessage textMessage = (TextMessage)replyMessage;
	return textMessage.getText();
}

/**
 * 订单入队列
 * @param info
 * @throws JMSException 
 */
public String sendObjectQueueMessage(final OrderInfo info) throws JMSException {
	Message message = jmsTemplate.sendAndReceive(activeMQQueue, new MessageCreator() {
		@Override
		public Message createMessage(Session session) throws JMSException {
			return session.createObjectMessage(info);
		}
	});
	
	log.info("sendTextAndReceive: {}", JSON.toJSONString(message));
	TextMessage textMessage = (TextMessage)message;
	return textMessage.getText();
}

5.可以模拟多个生产者，在高并发下，多台服务器请求进入消息队列，交给消费者统一生成订单，详见demo地址：
