1、配置檔案

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">
 


    <!-- 配置JMS連線工廠 -->
    <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="failover:(tcp://192.168.147.131:61616)" />
    </bean>

    <!-- 定義訊息佇列（Queue） -->
    <bean id="queueDestination" class
 
="org.apache.activemq.command.ActiveMQQueue">
        <!-- 設定訊息佇列的名字 -->
        <constructor-arg>
            <value>testSpringQueue</value>
        </constructor-arg>
    </bean>

    <!-- 配置JMS模板（Queue），Spring提供的JMS工具類，它傳送、接收訊息。 -->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="defaultDestination" ref="queueDestination" />
        <property name="receiveTimeout" value="10000" />
    </bean>
    
</beans>

2、生產者程式碼

package com.mq.spring.queue;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.annotation.Resource;
import javax.jms.*;

/**
 * created on 2015/6/4
 * @author [email protected]
 * @version 1.0
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring-mq-queue.xml"})
public class QueueSender {

    @Resource
    private JmsTemplate jmsTemplate;

    @Test
    public void send(){
        sendMqMessage(null,"spring activemq queue type message !");
    }

    /**
     * 說明:傳送的時候如果這裡沒有顯示的指定destination.將用spring xml中配置的destination
     * @param destination
     * @param message
     */
    public void sendMqMessage(Destination destination, final String message){
        if(null == destination){
            destination = jmsTemplate.getDefaultDestination();
        }
        jmsTemplate.send(destination, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(message);
            }
        });
        System.out.println("spring send message...");
    }

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

}

3、消費者程式碼

package com.mq.spring.queue;

import org.junit.Test;
import javax.jms.*;
import org.junit.runner.RunWith;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import javax.annotation.Resource;
import javax.jms.Message;

/**
 * created on 2015/6/4
 * @author [email protected]
 * @version 1.0
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring-mq-queue.xml"})
public class QueueReceiver {

    @Resource
    private JmsTemplate jmsTemplate;

    @Test
    public void receiveMqMessage(){
        Destination destination = jmsTemplate.getDefaultDestination();
        receive(destination);
    }

    /**
     * 接受訊息
     */
    public void receive(Destination destination) {
        TextMessage tm = (TextMessage) jmsTemplate.receive(destination);
        try {
            System.out.println("從佇列" + destination.toString() + "收到了訊息：\t" + tm.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

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

程式執行結果:

說明:上面的生產者和消費者使用同一套配置檔案,使用獨立的程式去接收訊息,spring jms也提供了訊息監聽處理.接下來我們換成監聽式消費

配置檔案如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <!-- 配置JMS連線工廠 -->
    <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="failover:(tcp://192.168.147.131:61616)" />
    </bean>

    <!-- 定義訊息佇列（Queue） -->
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <!-- 設定訊息佇列的名字 -->
        <constructor-arg>
            <value>testSpringQueue</value>
        </constructor-arg>
    </bean>

    <!-- 配置訊息佇列監聽者（Queue） -->
    <bean id="consumerMessageListener" class="com.mq.spring.queue.ConsumerMessageListener" />

    <!-- 訊息監聽容器（Queue），配置連線工廠，監聽的佇列是testSpringQueue，監聽器是上面定義的監聽器 -->
    <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>
    
</beans>

這樣我們的訊息消費就可以在監聽器中處理消費了.生產的程式碼不變,修改傳送者的訊息體內容,執行生產程式.可以看到執行效果如下:
