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"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:amq="http://activemq.apache.org/schema/core"
xmlns:jms="http://www.springframework.org/schema/jms"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/jms http://www.springframework.org/schema/jms/spring-jms-4.1.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core-5.12.1.xsd"
>

<context:component-scan base-package="com.gzframe.demo.activemq" />
<mvc:annotation-driven />

<amq:connectionFactory id="amqConnectionFactory"
brokerURL="tcp://192.168.150.61:61616"
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。
