### 前言 ###

在前面我们讲生产者和消费者的时候，代码编写的都比较基础，开发起来费时费力，下面我们将来介绍如何整合spring来简化开发；

### 整合配置 ###

pom增加依赖：

<dependency>
         <groupId>org.apache.activemq</groupId>
         <artifactId>activemq-pool</artifactId>
         <version>5.15.10</version>
     </dependency>
     
     <dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-jms</artifactId>
         <version>5.2.1.RELEASE</version>
     </dependency>
     
     <dependency>
         <groupId>org.apache.xbean</groupId>
         <artifactId>xbean-spring</artifactId>

     </dependency>
     <dependency>

     </dependency>
     <dependency>

     </dependency>
     <dependency>

         <artifactId>spring-aop</artifactId>
         <version>4.3.23.RELEASE</version>
     </dependency>
     <dependency>

         <artifactId>spring-orm</artifactId>
         <version>4.3.23.RELEASE</version>
     </dependency>

新建Spring整合activeMQ配置文件：

<?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"
           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.xsd">
    
         
        <context:component-scan base-package="com.chaytech.activemq"/>
    
        
        <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
            <property name="connectionFactory">
                
                <bean class="org.apache.activemq.spring.ActiveMQConnectionFactory">
                    
                    <property name="brokerURL" value="tcp://192.168.0.166:61616"/>
                </bean>
            </property>
    
            
            <property name="maxConnections" value="100"/>
        </bean>
    
        
        <bean id="destinationQueue" class="org.apache.activemq.command.ActiveMQQueue">
            
            <constructor-arg index="0" value="spring-active-queue"/>
        </bean>
    
        
        <bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
            <constructor-arg index="0" value="spring-active-topic"/>
        </bean>
    
        
        <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
            
            <property name="connectionFactory" ref="connectionFactory"/>
            
            <property name="defaultDestination" ref="destinationQueue"/>
            
            <property name="messageConverter">
                <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
            </property>
        </bean>
    </beans>

### 队列生产者和消费者 ###

package com.chaytech.activemq.spring;
    
    import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.ApplicationContext;
    import org.springframework.jms.core.JmsTemplate;
    import org.springframework.stereotype.Service;
    
    /**

     *
     * @author Chency
     * @email chaytech@163.com
     * @Date 2020/03/24 21:41
     */
    @Service
    public class SpringJmsProducer {
    
        @Autowired
        private JmsTemplate jmsTemplate;
    
        public static void main(String[] args) {
            ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-activemq.xml");
    
            SpringJmsProducer springJmsProducer = (SpringJmsProducer)applicationContext.getBean("springJmsProducer");
            springJmsProducer.jmsTemplate.send((session) -> {
                return session.createTextMessage("spring整合activeMQ。。");
            });
        }
    }

package com.chaytech.activemq.spring;
    
    import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.ApplicationContext;
    import org.springframework.jms.core.JmsTemplate;
    import org.springframework.stereotype.Service;
    
    /**
     * activeMQ整合spring-消费者
     *
     * @author Chency
     * @email chaytech@163.com
     * @Date 2020/03/24 21:41
     */
    @Service
    public class SpringJmsConsumer {
    
        @Autowired
        private JmsTemplate jmsTemplate;
    
        public static void main(String[] args) {
            ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-activemq.xml");
    
            SpringJmsConsumer springJmsConsumer = (SpringJmsConsumer)applicationContext.getBean("springJmsConsumer");
    
            String message = (String) springJmsConsumer.jmsTemplate.receiveAndConvert();
            System.out.println("spring整合activeMQ消费者：" + message);
        }
    }

### 主题生产者和消费者 ###

主题生产者和消费者代码不用改变，只需修改配置文件即可，修改如下：

<bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg index="0" value="spring-active-topic"/>
    </bean>
    
    
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        
        <property name="connectionFactory" ref="connectionFactory"/>
        
        
        <property name="defaultDestination" ref="destinationTopic"/>
        
        <property name="messageConverter">
            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>

增加主题目的地，并将jmsTemplate中的defaultDestination指向我们新增的destinationTopic

### 消费者监听器 ###

前面我们消费者在消费消息的时候用的阻塞方式，下面将演示如何使用监听器的方式来消费消息，一旦配置了监听器，就不需要启动消费者了，生产者在发送消息的时候，监听器会自动消费

首先我们要先自定义一个消息监听器：

package com.chaytech.activemq.spring;
    
    import org.springframework.stereotype.Component;
    
    import javax.jms.JMSException;
    import javax.jms.Message;
    import javax.jms.MessageListener;
    import javax.jms.TextMessage;
    
    /**
     * 自定义消息监听器
     *
     * @author Chency
     * @email chaytech@163.com
     * @Date 2020/03/24 22:05
     */
    @Component
    public class CustomerMessageListener implements MessageListener {
    
        @Override
        public void onMessage(Message message) {
            if(message != null && message  instanceof TextMessage){
                TextMessage textMessage = (TextMessage) message;
                try {
                    System.out.println("自定义消息监听器监听到的消息：" + textMessage.getText());
                } catch (JMSException e) {
                    e.printStackTrace();
                }
            }
        }
    }

修改配置文件，增加监听器配置：

<bean id="messageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="destination" ref="destinationTopic"/>
        <property name="messageListener" ref="customerMessageListener"/>
    </bean>
