1、配置部分html

2、代碼部分java

3、頁面部分web

4、Controller控制器spring

5、效果展現apache

6、加入監聽器api

7、最最重要的，別忘了打賞spring-mvc

1、配置部分

ActiveMQ的安裝這就不說了，很簡單，服務器

這個例子採用maven構建，首先看一下pom.xml微信

接下來看一下web.xml，以下session

<?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">

        <url-pattern>/*</url-pattern>  
    </filter-mapping>
  
</web-app>

其中spring-root.xml 很簡單，負責加載一些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以下

<?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是關鍵的配置，以下

<?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/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鏈接工長 -->
    <bean id="connectionFactory"
        class="org.springframework.jms.connection.CachingConnectionFactory">
        <constructor-arg ref="amqConnectionFactory" />
        <property name="sessionCacheSize" value="100" />
    </bean>
    
    <!-- 定義消息隊列（Queue） -->
    <bean id="demoQueueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <!-- 設置消息隊列的名字 -->
        <constructor-arg>
            <value>gzframe.demo</value>
        </constructor-arg>
    </bean>
    
    <!-- 配置JMS模板（Queue），Spring提供的JMS工具類，它發送、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，默認是false，此處顯示寫出false -->
        <property name="pubSubDomain" value="false" />
    </bean>
    
 </beans>

2、代碼部分

消息生產者ProducerService.java，代碼以下

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;
       
      /**
       * 向指定隊列發送消息
       */
      public void sendMessage(Destination destination, final String msg) {
        System.out.println("向隊列" + destination.toString() + "發送了消息------------" + msg);
        jmsTemplate.send(destination, new MessageCreator() {
          public Message createMessage(Session session) throws JMSException {
            return session.createTextMessage(msg);
          }
        });
      }
     
    /**
     * 向默認隊列發送消息
     */
      public void sendMessage(final String msg) {
        String destination =  jmsTemplate.getDefaultDestination().toString();
        System.out.println("向隊列" +destination+ "發送了消息------------" + msg);
        jmsTemplate.send(new MessageCreator() {
          public Message createMessage(Session session) throws JMSException {
            return session.createTextMessage(msg);
          }
        });
     
      }
    
}

消費者ConsumerService.java，代碼以下

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("從隊列" + destination.toString() + "收到了消息：\t"
                    + tm.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
        
        return tm;
        
    }
 
}

3、頁面部分

1.首先寫一個歡迎頁，welcome.jsp以下，

<%@ 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">去發消息</a></h2>
    <h2><a href="receive">從隊列中取一個消息</a></h2>
</body>
</html>

2.而後是生產者頁面jms_producer.jsp，以下

<%@ 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">返回主頁</a></h2>
</body>
</html>

3.接收者頁面queue_receive.jsp，以下

<%@ 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">返回主頁</a></h2>
</body>
</html>

4、Controller控制器

1.首先controller到首頁welcome頁，WelcomeController.java以下：

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.而後定義消息生產和消費的控制器，DemoController.java，代碼以下

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 {


    //隊列名gzframe.demo
    @Resource(name="demoQueueDestination")
    private Destination demoQueueDestination;

    //隊列消息生產者
    @Resource(name="producerService")
    private ProducerService producer;
    
  //隊列消息消費者
    @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;
    }
    
    
    
}

5、效果展現

首先訪問歡迎頁，以下

而後點「去發消息」，進入到以下頁面，默認消息框一已經填寫了時間，點擊提交，會將時間「2015-12-25 11:51:25」提交到qctivemq服務器中，

提交完成後，根據頁面代碼，會轉到歡迎頁，在歡迎頁中既能夠點擊「從隊列中取一個消息」，效果以下

能夠看到，取到的消息即爲剛纔提交的時間，demo成功！

通過以上操做後的後臺輸出以下

6、加入監聽器

以上例子中，接收消息是靠手動點擊接收，下面將配置一個消息監聽器「QueueMessageListener.java」，負責自動監聽qctiveMQ中的隊列消息，

一旦有新消息後，將自動讀取消費，媽媽不再用擔憂漏掉消息啦！

1.首先寫一個監聽的類「QueueMessageListener.java」，必須實現「MessageListerner」接口，代碼以下

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 {

    
    //當收到消息後，自動調用該方法
    @Override
    public void onMessage(Message message) {
        
        TextMessage tm = (TextMessage) message;
        try {
            System.out.println("QueueMessageListener監聽到了文本消息：\t"
                    + tm.getText());
            //do something ...
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

}

2.寫完監聽類後，打開activemq.xml配置文件，須要將這個監聽配置到文件中，這樣，應用加載後，即會加載此監聽。
將如下的配置段加入到activemq.xml中

<!-- 配置消息隊列監聽者（Queue） -->
    <bean id="queueMessageListener" class="com.gzframe.demo.activemq.listener.QueueMessageListener" />
    
    <!-- 顯示注入消息監聽容器（Queue），配置鏈接工廠，監聽的目標是demoQueueDestination，監聽器是上面定義的監聽器 -->
    <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>
