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"

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"

        <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/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/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;

@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;

    }

}

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;

@Controller
public 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;

@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;
    }

}

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
