七、最最重要的，别忘了打赏

一、配置部分

ActiveMQ的安装这就不说了，很简单，

这个例子采用maven构建，首先看一下pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">    <modelVersion>4.0.0</modelVersion>  <groupId>com.gzframe.demo</groupId>  <artifactId>gzframe</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>gzframe Maven Webapp</name>  <url>http://maven.apache.org</url>    <!-- 版本管理 -->  <properties>      <springframework>4.1.8.RELEASE</springframework>      <javax.servlet>3.1.0</javax.servlet>  </properties>    <dependencies>        <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>4.10</version>      <scope>test</scope>    </dependency>        <dependency>        <groupId>jstl</groupId>        <artifactId>jstl</artifactId>        <version>1.2</version>    </dependency>        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>servlet-api</artifactId>        <version>${javax.servlet}</version>    </dependency>        <!-- spring -->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-core</artifactId>        <version>${springframework}</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-context</artifactId>        <version>${springframework}</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-tx</artifactId>        <version>${springframework}</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-webmvc</artifactId>        <version>${springframework}</version>    </dependency>    <dependency>          <groupId>org.springframework</groupId>          <artifactId>spring-jms</artifactId>          <version>${springframework}</version>      </dependency>    <!-- xbean 如<amq:connectionFactory /> -->    <dependency>        <groupId>org.apache.xbean</groupId>        <artifactId>xbean-spring</artifactId>        <version>3.16</version>    </dependency>        <!-- 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>        </dependencies>      <build>    <finalName>gzframe</finalName>  </build></project>

接下来看一下web.xml，如下

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee"            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"            xsi:schemaLocation="http://java.sun.com/xml/ns/javaee           http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"          version="3.0">  <display-name>Archetype Created Web Application</display-name>    <!-- 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>    <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <servlet>        <servlet-name>springMVC</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:spring-mvc-dispatch.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>springMVC</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>        <!-- 处理编码格式 -->    <filter>          <filter-name>characterEncodingFilter</filter-name>          <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>          <init-param>              <param-name>encoding</param-name>              <param-value>UTF-8</param-value>          </init-param>          <init-param>              <param-name>forceEncoding</param-name>              <param-value>true</param-value>          </init-param>      </filter>      <filter-mapping>          <filter-name>characterEncodingFilter</filter-name>          <url-pattern>/*</url-pattern>      </filter-mapping>  </web-app>

其中spring-root.xml 很简单，负责加载一些spring的配置

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

spring-mvc-dispatch.xml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: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.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">             <context:component-scan base-package="com.gzframe.demo.mvc.controller" />    <mvc:annotation-driven />         <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">        <property name="viewClass"            value="org.springframework.web.servlet.view.JstlView" />        <property name="prefix" value="/WEB-INF/views/" />        <property name="suffix" value=".jsp" />    </bean></beans>

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>

二、代码部分

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;@Servicepublic 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;@Servicepublic 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;            } }

三、页面部分

1.首先写一个欢迎页，welcome.jsp如下，

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Welcome</title></head><body>    <h1>Welcome!!!</h1>    <h2><a href="producer">去发消息</a></h2>    <h2><a href="receive">从队列中取一个消息</a></h2></body></html>

2.然后是生产者页面jms_producer.jsp，如下

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>JMS-Producer</title></head><body>    <h1>JMS-Producer!!!</h1>    <form action="onsend" method="post">                MessageText:<textarea name="message">${time }</textarea>                <input type="submit" value="提交" />    </form>    <h2><a href="welcome">返回主页</a></h2></body></html>

3.接收者页面queue_receive.jsp，如下

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Receive</title></head><body>    <h1>${textMessage }</h1>    <h2><a href="welcome">返回主页</a></h2></body></html>

四、Controller控制器

1.首先controller到首页welcome页，WelcomeController.java如下：

package com.gzframe.demo.mvc.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.servlet.ModelAndView;@Controllerpublic class WelcomeController {        @RequestMapping(value="/welcome",method=RequestMethod.GET)    public ModelAndView welcome(){        System.out.println("------------welcome");                ModelAndView mv = new ModelAndView();        mv.setViewName("welcome");        return mv;    }}

2.然后定义消息生产和消费的控制器，DemoController.java，代码如下

package com.gzframe.demo.mvc.controller;import java.io.IOException;import java.text.SimpleDateFormat;import java.util.*;import javax.annotation.Resource;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.TextMessage;import javax.management.MBeanServerConnection;import javax.management.remote.JMXConnector;import javax.management.remote.JMXConnectorFactory;import javax.management.remote.JMXServiceURL;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.servlet.ModelAndView;import com.gzframe.demo.activemq.consumer.ConsumerService;import com.gzframe.demo.activemq.producer.ProducerService;@Controllerpublic 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;    }            }

五、效果展示

首先访问欢迎页，如下

然后点“去发消息”，进入到如下页面，默认消息框一已经填写了时间，点击提交，会将时间“2015-12-25 11:51:25”提交到qctivemq服务器中，

提交完成后，根据页面代码，会转到欢迎页，在欢迎页中既可以点击“从队列中取一个消息”，效果如下

可以看到，取到的消息即为刚才提交的时间，demo成功！

经过以上操作后的后台输出如下

六、加入监听器

以上例子中，接收消息是靠手动点击接收，下面将配置一个消息监听器“QueueMessageListener.java”，负责自动监听qctiveMQ中的队列消息，

一旦有新消息后，将自动读取消费，妈妈再也不用担心漏掉消息啦！

1.首先写一个监听的类“QueueMessageListener.java”，必须实现“MessageListerner”接口，代码如下

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();        }    }}

2.写完监听类后，打开activemq.xml配置文件，需要将这个监听配置到文件中，这样，应用加载后，即会加载此监听。
将以下的配置段加入到activemq.xml中

<!-- 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>

3.测试

配置完成后，重新启动服务，去消息发送页提交消息，提交完毕后，监听检测到，将立即消费掉，并在后台打印出来

后台输出如下
