springMVC下集成active MQ发送邮件

环境：本地需安装activemq，且访问正常，安装方法网上很多，这里省略。

1.添加相关jar包，我这里使用的是maven，你也可以选择其他方式添加。下面是maven相关配置：

 <!--  ActiveMQ JMS 相关jar begin -->
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-broker</artifactId>
            <version>5.8.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-client</artifactId>
            <version>5.14.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.geronimo.specs</groupId>
            <artifactId>geronimo-j2ee-management_1.1_spec</artifactId>
            <version>1.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.apache.geronimo.specs</groupId>
            <artifactId>geronimo-jms_1.1_spec</artifactId>
            <version>1.1.1</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.6.6</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jms</artifactId>
            <version>4.1.5.RELEASE</version>
        </dependency>

        <!--  ActiveMQ JMS 相关jar end -->

2.编写发送和接收处理类

public class MyMessageConverter implements MessageConverter {  

    public Message toMessage(Object object, Session session)
            throws JMSException, MessageConversionException {
        return session.createObjectMessage((Serializable) object);
    }  

    public Object fromMessage(Message message) throws JMSException,
            MessageConversionException {
        ObjectMessage objMessage = (ObjectMessage) message;
        return objMessage.getObject();
    }  

3.编写发送实现类，接口类这里就不贴了。

public class ProducerServiceImpl implements ProducerService {

    private JmsTemplate jmsTemplate;

    protected final Logger logger = Logger.getLogger(getClass());

    public void sendMessage(final Serializable obj) {
        logger.debug("---------------生产者向MQ发送消息-----------------");
        jmsTemplate.convertAndSend(obj);
    } 

    public JmsTemplate getJmsTemplate() {
        return jmsTemplate;
    } 

    @Resource
    public void setJmsTemplate(JmsTemplate jmsTemplate) {
        this.jmsTemplate = jmsTemplate;
    }

4.编写监听类

public class MyMessageListener implements MessageListener {  

    @Autowired
    private  MyMessageConverter messageConverter;  

    protected final Logger logger = Logger.getLogger(getClass());

    public void onMessage(Message message) {
        if (message instanceof ObjectMessage) {
            ObjectMessage objMessage = (ObjectMessage) message;
            try {
                Mail mail = (Mail) messageConverter.fromMessage(objMessage);
                logger.debug("接收到一个ObjectMessage，包含Email对象，准备发送邮件！");
                new MailUtil().send(mail);
            } catch (JMSException e) {
                logger.info("接收到一个ObjectMessage，但处理失败！");
            }
        }
    }  

5.配置XML

<context:component-scan base-package="com.guesslive" />
    <!-- Spring提供的JMS工具类，它可以进行消息发送、接收等 -->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->
        <property name="connectionFactory" ref="connectionFactory"/>
        <!-- 消息转换器 -->
        <property name="messageConverter" ref="emailMessageConverter"/>
        <property name="defaultDestination" ref="queueDestination" />
        <property name="explicitQosEnabled" value="true" /> <!-- deliveryMode, priority, timeToLive 的开关，要生效，必须配置为true，默认false-->
        <property name="deliveryMode" value="2" /> <!-- 发送模式  DeliveryMode.NON_PERSISTENT=1:非持久 ; DeliveryMode.PERSISTENT=2:持久 默认2-持久-->
    </bean>
    <!-- 类型转换器 -->
    <bean id="emailMessageConverter" class="com.guesslive.admin.common.mq.MyMessageConverter"/>  

    <!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供-->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://127.0.0.1:61616"/>
        <property name="userName" value="admin"/>
        <property name="password" value="admin"/>
        <property name="useAsyncSend" value="true" />
        <!-- 如果传输的对象是Obeject 这里必须加上这句  否则会导致对象序列化失败 出现classnotfound异常  详细： http://activemq.apache.org/objectmessage.html -->
        <property name="trustAllPackages" value="true"/>
    </bean>  

    <!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
    <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
        <property name="targetConnectionFactory" ref="targetConnectionFactory"/>
    </bean>
    <!--队列目的地-->
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg>
            <value>email</value>
        </constructor-arg>
    </bean>
    <!-- 消息监听器 -->
    <bean id="consumerMessageListener" class="com.guesslive.admin.common.mq.MyMessageListener"/>
    <!-- 消息监听容器 -->
    <bean id="jmsContainer"
        class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="destination" ref="queueDestination" />
        <property name="messageListener" ref="consumerMessageListener" />
    </bean>

6.发送和接收

//调用向MQ推送消息的方法
producerService.sendMessage(mail);
