SpringMVC4整合ActiveMQ实现消息队列

1.配置ActiveMQ

 <!-- activemq -->
    <dependency>  
        <groupId>org.apache.activemq</groupId>  
        <artifactId>activemq-core</artifactId>  
        <version>5.7.0</version>
    </dependency> 
    <dependency>  
        <groupId>org.apache.activemq</groupId>  
        <artifactId>activemq-pool</artifactId>  
        <version>5.12.1</version>  
    </dependency>  
<!--引入ActivieMQ -->

加载activemq.xml

<!-- 加载spring的配置文件，例如hibernate、jms等集成 -->
  <context-param>  
      <param-name>contextConfigLocation</param-name>  
      <param-value>
          classpath:spring-root.xml;
         classpath:activemq.xml;
     </param-value>  
  </context-param>

activemq.xml是关键的配置，如下

<?xml version="1.0" encoding="UTF-8"?>

    <amq:connectionFactory id="amqConnectionFactory"

        userName="admin" 
        password="admin" />
    
    <!-- 配置JMS连接工长 -->
    <bean id="connectionFactory"
        class="org.springframework.jms.connection.CachingConnectionFactory">
        <constructor-arg ref="amqConnectionFactory" />
        <property name="sessionCacheSize" value="100" />
    </bean>
    
    <!-- 定义消息队列（Queue） -->
    <bean id="demoQueueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <!-- 设置消息队列的名字 -->
        <constructor-arg>
            <value>gzframe.demo</value>
        </constructor-arg>
    </bean>

<!-- 配置消息队列监听者（Queue） -->
    <bean id="queueMessageListener" class="com.gzframe.demo.activemq.listener.QueueMessageListener" />
    
    <!-- 显示注入消息监听容器（Queue），配置连接工厂，监听的目标是demoQueueDestination，监听器是上面定义的监听器 -->
    <bean id="queueListenerContainer"
        class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="destination" ref="demoQueueDestination" />
        <property name="messageListener" ref="queueMessageListener" />
    </bean>
    
    <!-- 配置JMS模板（Queue），Spring提供的JMS工具类，它发送、接收消息。 -->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="defaultDestination" ref="demoQueueDestination" />
        <property name="receiveTimeout" value="10000" />
        <!-- true是topic，false是queue，默认是false，此处显示写出false -->
        <property name="pubSubDomain" value="false" />
    </bean>
    
 </beans>

消息生产者ProducerService.java，代码如下

package com.gzframe.demo.activemq.producer;

import javax.annotation.Resource;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;

@Service
public class ProducerService {

    @Resource(name="jmsTemplate")
    private JmsTemplate jmsTemplate;
       
      /**
       * 向指定队列发送消息
       */
      public void sendMessage(Destination destination, final String msg) {
        System.out.println("向队列" + destination.toString() + "发送了消息------------" + msg);
        jmsTemplate.send(destination, new MessageCreator() {
          public Message createMessage(Session session) throws JMSException {
            return session.createTextMessage(msg);
          }
        });
      }
     
    /**
     * 向默认队列发送消息
     */
      public void sendMessage(final String msg) {
        String destination =  jmsTemplate.getDefaultDestination().toString();
        System.out.println("向队列" +destination+ "发送了消息------------" + msg);
        jmsTemplate.send(new MessageCreator() {
          public Message createMessage(Session session) throws JMSException {
            return session.createTextMessage(msg);
          }
        });
     
      }
    
}

消费者ConsumerService.java，代码如下

package com.gzframe.demo.activemq.consumer;

import javax.annotation.Resource;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.TextMessage;

import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;


@Service
public class ConsumerService {

    @Resource(name="jmsTemplate")
    private JmsTemplate jmsTemplate;
     
    /**
     * 接收消息
     */
    public TextMessage receive(Destination destination) {
        TextMessage tm = (TextMessage) jmsTemplate.receive(destination);
        try {
            System.out.println("从队列" + destination.toString() + "收到了消息：\t"
                    + tm.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
        
        return tm;
        
    }
 
}

如何调用消息队列

@Controller
public class DemoController {


    //队列名gzframe.demo
    @Resource(name="demoQueueDestination")
    private Destination demoQueueDestination;

    //队列消息生产者
    @Resource(name="producerService")
    private ProducerService producer;
    
  //队列消息消费者
    @Resource(name="consumerService")
    private ConsumerService consumer;
    
    @RequestMapping(value="/producer",method=RequestMethod.GET)
    public ModelAndView producer(){
        System.out.println("------------go producer");
        
        Date now = new Date(); 
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String time = dateFormat.format( now ); 
        System.out.println(time);
        
        ModelAndView mv = new ModelAndView();
        mv.addObject("time", time);
        mv.setViewName("jms_producer");        
        return mv;
    }
    
    @RequestMapping(value="/onsend",method=RequestMethod.POST)
    public ModelAndView producer(@RequestParam("message") String message) {
        System.out.println("------------send to jms");
        ModelAndView mv = new ModelAndView();
        producer.sendMessage(demoQueueDestination, message);
        mv.setViewName("welcome");
        return mv;
    }
    
    @RequestMapping(value="/receive",method=RequestMethod.GET)
    public ModelAndView queue_receive() throws JMSException {
        System.out.println("------------receive message");
        ModelAndView mv = new ModelAndView();
        
        TextMessage tm = consumer.receive(demoQueueDestination);
        mv.addObject("textMessage", tm.getText());
        
        mv.setViewName("queue_receive");
        return mv;
    }
    
    /*
     * ActiveMQ Manager Test
     */
    @RequestMapping(value="/jms",method=RequestMethod.GET)
    public ModelAndView jmsManager() throws IOException {
        System.out.println("------------jms manager");
        ModelAndView mv = new ModelAndView();
        mv.setViewName("welcome");
        
        JMXServiceURL url = new JMXServiceURL("");
        JMXConnector connector = JMXConnectorFactory.connect(url);
        connector.connect();
        MBeanServerConnection connection = connector.getMBeanServerConnection();
        
        return mv;
    }
    
    
    
}

消息监听器

package com.gzframe.demo.activemq.listener;

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


public class QueueMessageListener implements MessageListener {

    
    //当收到消息后，自动调用该方法
    @Override
    public void onMessage(Message message) {
        
        TextMessage tm = (TextMessage) message;
        try {
            System.out.println("QueueMessageListener监听到了文本消息：\t"
                    + tm.getText());
            //do something ...
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

}

这样实现消息队列。
