<bean id="jmsTemplate"
        class="org.springframework.jms.core.JmsTemplate102">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="timeToLive" value="86400000"/>
        <property name="defaultDestinationName" value="cmpp" />
        <property name="messageConverter" ref="messageConverter" />
        <property name="receiveTimeout" value="30000" />
    </bean>
上面的配置中用到了第一步配置的connectionFactory以及一个消息转换的类 messageConverter，这个类实现了 org.springframework.jms.support.converter.MessageConverter接口，可以在消息发送之前和接受之后进行消息类型转换。具体的看最后的实例代码。配置代码如下：
 <!-- Spring JMS SimpleConverter -->
       <bean id="simpleConverter"  class="org.springframework.jms.support.converter.SimpleMessageConverter" />
<!-- Message Converter -->
    <bean id="messageConverter"
        class="com.liangj.apmgt.jms.ApmgtMessageConverter">
        <property name="converter">
            <ref local="simpleConverter" />
        </property>
    </bean>

4。配置发送代码
    <bean id="producer"
        class="com.liangj.apmgt.jms.DefaultApmgtMessageProducer">
        <property name="jmsTemplate" ref="jmsTemplate" />
    </bean>
5。接着配置监听器，这是Spring2.0新增的功能，配置如下：
<!-- this is the Message Driven POJO (MDP) -->
    <bean id="messageListener"
        class="org.springframework.jms.listener.adapter.MessageListenerAdapter">
        <constructor-arg>
            <bean
                class="com.liangj.apmgt.jms.DefaultApmgtMessageListener" />
        </constructor-arg>
        <property name="defaultListenerMethod" value="onMessage" />
        <property name="messageConverter" ref="messageConverter" />
    </bean>

    <!-- and this is the attendant message listener container -->
    <bean id="listenerContainer"
        class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="destinationName" value="${jms.destinationName.cmpp}" />
        <property name="messageSelector" value="${jms.messageSelector}" />
        <property name="messageListener" ref="messageListener" />
    </bean>

 Spring配置监听器有很多种选择，在这里我选择这回种MessageListenerAdapter方法主要是因为这个方法比较灵活。实现他只要一个很普通的java类即可，和JMS以及Spring的耦合度最低。其中方法onMessage可以随便修改方法名，只要在配置文件中对应的修改就好了。
     MessageListenerAdapter还有一个功能就是如果处理方法(我这里是onMessage)返回一个非空值，它将自动返回一个响应消息。这个消息会返回给JMS Reply-To属性定义的目的地(如果存在)，或者是MessageListenerAdapter设置(如果配置了)的缺省目的地；如果没有定义目的地，那么将产生一个InvalidDestinationException异常(此异常将不会只被捕获而不处理，它将沿着调用堆栈上传)。
     这样我们的配置就都完成了。接下来我们来实现对应的Java文件
先是接口文件发送消息接口IApmgtMessageProducer.java
public interface IApmgtMessageProducer {
    public abstract void sendMessage(ApmgtMessageData messageData);
}
接受消息接口IApmgtMessageListener.java
public interface IApmgtMessageListener {
    public void onMessage(ApmgtMessageData message);
}
发消息的文件DefaultApmgtMessageProducer.java
 public class DefaultApmgtMessageProducer implements IApmgtMessageProducer {
   
    private JmsTemplate jmsTemplate;

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

    public void sendMessage(ApmgtMessageData messageData) {
        this.jmsTemplate.convertAndSend(messageData);
    }
}
收消息文件DefaultApmgtMessageListener.java
public class DefaultApmgtMessageListener implements IApmgtMessageListener {
    public void onMessage(ApmgtMessageData message) {
        System.out.println("监听到消息："+message);
    }
}
消息转换类ApmgtMessageConverter.java
public class ApmgtMessageConverter implements MessageConverter {

    private Log log = LogFactory.getLog(ApmgtMessageConverter.class);

    private SimpleMessageConverter converter;

    public void setConverter(SimpleMessageConverter converter) {
        this.converter = converter;
    }

    public Object fromMessage(Message message) throws JMSException, MessageConversionException {
        if (message instanceof ObjectMessage) {
            ObjectMessage o_message = (ObjectMessage)message;
            MessageHeader header = new MessageHeader();
            header.setId(message.getLongProperty("id"));
            header.setReceiver(message.getIntProperty("receiver"));
            header.setSender(message.getIntProperty("sender"));
            header.setSendPerson(message.getStringProperty("sendPerson"));
            header.setType(message.getIntProperty("type"));
            Serializable messageContent = o_message.getObject();
            ApmgtMessageData<Serializable> messageData = new ApmgtMessageData<Serializable>();
            messageData.setMessageContent(messageContent);
            messageData.setMessageHeader(header);
            return messageData;
        }
        return null;
    }

    public Message toMessage(Object object, Session session) throws JMSException, MessageConversionException {
        if (object instanceof ApmgtMessageData) {
            ApmgtMessageData data = (ApmgtMessageData) object;
            Message message = converter.toMessage(data.getMessageContent(), session);
            message.setLongProperty("id", data.getMessageHeader().getId());
            message.setIntProperty("receiver", data.getMessageHeader().getReceiver());
            message.setIntProperty("sender", data.getMessageHeader().getSender());
            message.setIntProperty("type", data.getMessageHeader().getType());
            message.setStringProperty("sendPerson", data.getMessageHeader().getSendPerson());
            log.info("发送消息[MessageSender]:\n" + message);
             return message;
        } else {
            return null;
        }
    }

}
消息类文件  消息父类：ApmgtMessageData.java
public class ApmgtMessageData<T extends Serializable>{

    protected T messageContent;
   
    protected MessageHeader messageHeader;

    public T getMessageContent() {
        return this.messageContent;
    }

    public MessageHeader getMessageHeader() {
        return this.messageHeader;
    }

    public void setMessageContent(T messageContent) {
        this.messageContent = messageContent;
    }
    public void setMessageHeader(MessageHeader messageHeader) {
        this.messageHeader = messageHeader;
    }

}
消息属性的一个类MessageHeader.java
public class MessageHeader {

    /**
     * 消息ID
     */
    private long id;

    /**
     * 消息类型
     */
    private int type;

    /**
     * 消息发送方，发送消息的模块
     */
    private int sender;

    /**
     * 消息接收方，接收消息的模块
     */
    private int receiver;

    /**
     * 消息发送者，具体的用户
     */
    private String sendPerson;

    public MessageHeader(){
        this.id = System.currentTimeMillis() ;
    }
   
    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getSendPerson() {
        return sendPerson;
    }

    public void setSendPerson(String sendPerson) {
        this.sendPerson = sendPerson;
    }

    public int getReceiver() {
        return receiver;
    }

    public void setReceiver(int receiver) {
        this.receiver = receiver;
    }

    public int getSender() {
        return sender;
    }

    public void setSender(int sender) {
        this.sender = sender;
    }

    public int getType() {
        return type;
    }

    public void setType(int type) {
        this.type = type;
    }

}
