6.1. Spring对ActiveMQ队列、主题的整合

  1. Spring配置文件

    这里在JmsTemplate的defaultDestination属性上配置的是队列,如果需要使用主题,只需要修改这个属性值,其他代码不用修改。

<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 https://www.springframework.org/schema/context/spring-context.xsd">

    <!--  开启包的自动扫描  -->
    <context:component-scan base-package="study.hwj.activemq"/>

    <!--  配置生产者  -->
    <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
        <property name="connectionFactory">
            <!-- 真正可以生产Connection的ConnectionFactory,由对应的JMS服务商提供 -->
            <bean class="org.apache.activemq.spring.ActiveMQConnectionFactory">
                <property name="brokerURL" value="tcp://192.168.181.128:61616"/>
            </bean>
        </property>
        <property name="maxConnections" value="100"/>
    </bean>

    <!--  这个是队列目的地,点对点的Queue  -->
    <bean id="destinationQueue" class="org.apache.activemq.command.ActiveMQQueue">
        <!--    通过构造注入Queue名    -->
        <constructor-arg index="0" value="spring-activemq-queue"/>
    </bean>

    <!--  这个是队列目的地,  发布订阅的主题Topic-->
    <bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg index="0" value="spring-activemq-topic"/>
    </bean>

    <!--  Spring提供的JMS工具类,他可以进行消息发送,接收等  -->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <!--    传入连接工厂    -->
        <property name="connectionFactory" ref="connectionFactory"/>
        <!--    传入目的地    -->
        <property name="defaultDestination" ref="destinationQueue"/>
        <!--    消息自动转换器    -->
        <property name="messageConverter">
            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>
</beans>
  1. 生产者代码

    @Service
    public class SpringMQ_Producer {
    
        private JmsTemplate jmsTemplate;
    
        @Autowired
        public void setJmsTemplate(JmsTemplate jmsTemplate) {
            this.jmsTemplate = jmsTemplate;
        }
    
        public static void main(String[] args) {
            ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
            SpringMQ_Producer springMQ_producer = applicationContext.getBean(SpringMQ_Producer.class);
    
            springMQ_producer.jmsTemplate.send(new MessageCreator() {
                @Override
                public Message createMessage(Session session) throws JMSException {
                    return session.createTextMessage("***Spring和ActiveMQ的整合case111.....");
                }
            });
            // springMQ_producer.jmsTemplate.send(session -> session.createTextMessage("***Spring和ActiveMQ的整合case111....."));
            System.out.println("********send task over");
        }
    }
    
  2. 消费者代码

@Service
public class SpringMQ_Consumer {

    private JmsTemplate jmsTemplate;

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

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        SpringMQ_Consumer springMQ_consumer = applicationContext.getBean(SpringMQ_Consumer.class);
        String returnValue = (String) springMQ_consumer.jmsTemplate.receiveAndConvert();
        System.out.println("****消费者收到的消息:   " + returnValue);
    }
}

6.2. ActiveMQ主题监听器

  1. Spring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 https://www.springframework.org/schema/context/spring-context.xsd">
    
        <!--  开启包的自动扫描  -->
        <context:component-scan base-package="study.hwj.activemq"/>
    
        <!--  配置生产者  -->
        <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
            <property name="connectionFactory">
                <!-- 真正可以生产Connection的ConnectionFactory,由对应的JMS服务商提供 -->
                <bean class="org.apache.activemq.spring.ActiveMQConnectionFactory">
                    <property name="brokerURL" value="tcp://192.168.181.128:61616"/>
                </bean>
            </property>
            <property name="maxConnections" value="100"/>
        </bean>
    
        <!--  这个是队列目的地,点对点的Queue  -->
        <bean id="destinationQueue" class="org.apache.activemq.command.ActiveMQQueue">
            <!--    通过构造注入Queue名    -->
            <constructor-arg index="0" value="spring-activemq-queue"/>
        </bean>
    
        <!--  这个是队列目的地,  发布订阅的主题Topic-->
        <bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
            <constructor-arg index="0" value="spring-activemq-topic"/>
        </bean>
    
        <!--  Spring提供的JMS工具类,他可以进行消息发送,接收等  -->
        <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
            <!--    传入连接工厂    -->
            <property name="connectionFactory" ref="connectionFactory"/>
            <!--    传入目的地    -->
            <property name="defaultDestination" ref="destinationTopic"/>
            <!--    消息自动转换器    -->
            <property name="messageConverter">
                <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
            </property>
        </bean>
    
        <!--  配置Jms消息监听器  -->
        <bean id="defaultMessageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
            <!--  Jms连接的工厂     -->
            <property name="connectionFactory" ref="connectionFactory"/>
            <!--   设置默认的监听目的地     -->
            <property name="destination" ref="destinationTopic"/>
            <!--  指定自己实现了MessageListener的类     -->
            <property name="messageListener" ref="myMessageListener"/>
        </bean>
    
        <bean id="myMessageListener" class="study.hwj.activemq.MyMessageListener"/>
    </beans>
    
  2. 监听器代码

/**
 * 实现MessageListener的类,需要把这个类交给xml配置里面的DefaultMessageListenerContainer管理
 */
public class MyMessageListener implements MessageListener {

    @Override
    public void onMessage(Message message) {
        if (message instanceof TextMessage) {
            TextMessage textMessage = (TextMessage) message;
            try {
                System.out.println("Listener收到的消息" + textMessage.getText());
            } catch (JMSException e) {
                e.printStackTrace();
            }
        }
    }
}
  1. 生产者代码

    与6.1. 中的生产者代码相同
