使用spring + ActiveMQ 总结

jopen 10年前

Spring 整合JMS 基于ActiveMQ 实现消息的发送接收

看了网上很多文件，最后总结出了自己需要的。

一、下载并安装ActiveMQ

首先我们到apache官网上下载activeMQ（http://activemq.apache.org/download.html），进行解压后运行其bin目录下面的activemq.bat文件启动activeMQ。

二、Spring中加入ActiveMQ的配置

首先将相关的jar拷贝到项目的lib文件下

配置之前先看一下相关目录以便于理解

下面开始配置

<bean id="connectinFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
  
  <property name="brokerURL" value="${mqUrl}" />
</bean>


<bean id="cachingConnectionFactory"
  class="org.springframework.jms.connection.CachingConnectionFactory">
  
  <property name="targetConnectionFactory" ref="connectinFactory"></property>
  
  <property name="sessionCacheSize" value="10"></property>
</bean>

</bean>

<bean id="queueMessageListener" class="com.common.jms.QueueMessageListener">
<property name="messageConverter" ref="messageConverter"></property>
</bean>
<bean id="topicMessageListener" class="com.common.jms.TopicMessageListener">
<property name="messageConverter" ref="messageConverter"></property>
</bean>
<bean id="messageConverter" class="com.common.jms.NotifyMessageConverter">
</bean>

下面展示一下Sender

public class Sender {
private static ServletContext servletContext;
private static WebApplicationContext ctx;
/**
* 发送点对点信息
* @param noticeInfo
*/
public static void setQueueSender(){
  servletContext = ServletActionContext.getServletContext();
  ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext);
   QueueMessageProducer notifyMessageProducer = ((QueueMessageProducer) ctx.getBean("queueMessageProducer"));
   PhoneNoticeInfo noticeInfo = new PhoneNoticeInfo();

（下面先展示PhoneNoticeInfo 然后是 QueueMessageProducer ）
   noticeInfo.setNoticeContent("Hello Word");
   noticeInfo.setNoticeTitle("hello Word");
   noticeInfo.setReceiver("hello");
   noticeInfo.setReceiverPhone("1111111");
   notifyMessageProducer.sendQueue(noticeInfo);
  }

public static ServletContext getServletContext() {
  return servletContext;
}
public static void setServletContext(ServletContext servletContext) {
  Sender.servletContext = servletContext;
}
public static WebApplicationContext getCtx() {
  return ctx;
}
public static void setCtx(WebApplicationContext ctx) {
  Sender.ctx = ctx;
}
}

PhoneNoticeInfo

public class PhoneNoticeInfo implements Serializable {
/** 消息标题 */
public String noticeTitle;
/** 消息内容 */
public String noticeContent;
/** 接收者 */
public String receiver;
/** 接收手机号 */
public String receiverPhone;
public String getNoticeTitle() {
  return noticeTitle;
}
public void setNoticeTitle(String noticeTitle) {
  this.noticeTitle = noticeTitle;
}
public String getNoticeContent() {
  return noticeContent;
}
public void setNoticeContent(String noticeContent) {
  this.noticeContent = noticeContent;
}
public String getReceiver() {
  return receiver;
}
public void setReceiver(String receiver) {
  this.receiver = receiver;
}

public String getReceiverPhone() {
return receiverPhone;
}
public void setReceiverPhone(String receiverPhone) {
this.receiverPhone = receiverPhone;
}

}

QueueMessageProducer

/**
* 消息生产者服务类
*/
public class QueueMessageProducer {
private JmsTemplate jmsTemplate;
private Destination notifyQueue;
private NotifyMessageConverter messageConverter;
public void sendQueue(PhoneNoticeInfo noticeInfo){
  sendMessage(noticeInfo);
}
private void sendMessage(PhoneNoticeInfo noticeInfo) {
  // TODO Auto-generated method stub
  jmsTemplate.setMessageConverter(messageConverter);
  jmsTemplate.setPubSubDomain(false);
  jmsTemplate.convertAndSend(notifyQueue,noticeInfo);
}
public JmsTemplate getJmsTemplate() {
  return jmsTemplate;
}
public void setJmsTemplate(JmsTemplate jmsTemplate) {
  this.jmsTemplate = jmsTemplate;
}
public Destination getNotifyQueue() {
  return notifyQueue;
}
public void setNotifyQueue(Destination notifyQueue) {
  this.notifyQueue = notifyQueue;
}
public NotifyMessageConverter getMessageConverter() {
  return messageConverter;
}
public void setMessageConverter(NotifyMessageConverter messageConverter) {
  this.messageConverter = messageConverter;
}
}

NotifyMessageConverter

/**
* 消息转换
*/
public class NotifyMessageConverter implements MessageConverter {
private static Logger logger = LoggerFactory.getLogger(NotifyMessageConverter.class);
@Override
/**
* 转换接收到的消息为NoticeInfo对象
*/
public Object fromMessage(Message message) throws JMSException,
   MessageConversionException {
  // TODO Auto-generated method stub
  if (logger.isDebugEnabled()) {
   logger.debug("Receive JMS message :"+message);
  }
  if (message instanceof ObjectMessage) {
   ObjectMessage oMsg = (ObjectMessage)message;
   if (oMsg instanceof ActiveMQObjectMessage) {
    ActiveMQObjectMessage aMsg = (ActiveMQObjectMessage)oMsg;
    try {
     PhoneNoticeInfo noticeInfo = (PhoneNoticeInfo)aMsg.getObject();
     return noticeInfo;
    } catch (Exception e) {
     // TODO: handle exception
     logger.error("Message:${} is not a instance of NoticeInfo."+message.toString());
     throw new JMSException("Message:"+message.toString()+"is not a instance of NoticeInfo."+message.toString());
    }
   }else{
    logger.error("Message:${} is not a instance of ActiveMQObjectMessage."+message.toString());
    throw new JMSException("Message:"+message.toString()+"is not a instance of ActiveMQObjectMessage."+message.toString());
   }
  }else {
   logger.error("Message:${} is not a instance of ObjectMessage."+message.toString());
   throw new JMSException("Message:"+message.toString()+"is not a instance of ObjectMessage."+message.toString());
  }
}

@Override
/**
* 转换NoticeInfo对象到消息
*/
public Message toMessage(Object obj, Session session) throws JMSException,
   MessageConversionException {
  // TODO Auto-generated method stub
  if (logger.isDebugEnabled()) {
   logger.debug("Convert Notify object to JMS message:${}"+obj.toString());
  }
  if (obj instanceof PhoneNoticeInfo) {
   ActiveMQObjectMessage msg = (ActiveMQObjectMessage)session.createObjectMessage();
   msg.setObject((PhoneNoticeInfo)obj);
   return msg;
  }else {
   logger.debug("Convert Notify object to JMS message:${}"+obj.toString());
  }
  return null;
}

}

QueueMessageListener

public class QueueMessageListener implements MessageListener {
private static Logger logger = LoggerFactory.getLogger(QueueMessageListener.class);
private NotifyMessageConverter messageConverter;

/**
* 接收消息
*/
@Override
public void onMessage(Message message) {
  // TODO Auto-generated method stub
  try {
   ObjectMessage objectMessage = (ObjectMessage)message;
   PhoneNoticeInfo noticeInfo = (PhoneNoticeInfo)messageConverter.fromMessage(objectMessage);
   System.out.println("queue收到消息"+noticeInfo.getNoticeContent());
   System.out.println("model:"+objectMessage.getJMSDeliveryMode());
   System.out.println("destination:"+objectMessage.getJMSDestination());
   System.out.println("type:"+objectMessage.getJMSType());
   System.out.println("messageId:"+objectMessage.getJMSMessageID());
   System.out.println("time:"+objectMessage.getJMSTimestamp());
   System.out.println("expiredTime:"+objectMessage.getJMSExpiration());
   System.out.println("priority:"+objectMessage.getJMSPriority());

  } catch (Exception e) {
   // TODO: handle exception
   logger.error("处理信息时发生异常",e);
  }
}
public NotifyMessageConverter getMessageConverter() {
  return messageConverter;
}
public void setMessageConverter(NotifyMessageConverter messageConverter) {
  this.messageConverter = messageConverter;
}

}
