    </dependency>
</dependencies>

7.2、Spring 的 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 https://www.springframework.org/schema/context/spring-context.xsd">
    <!--  开启包的自动扫描  -->
    <context:component-scan base-package="com.cqupt.spring"/>
    <!--  配置生产者  -->

        <property name="connectionFactory">
            <bean class="org.apache.activemq.ActiveMQConnectionFactory">
                <property name="brokerURL" value="tcp://192.168.5.130:61616"/>
            </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">
        <constructor-arg index="0" value="spring-active-queue"/>
    </bean>
    <!--  这个是队列目的地,点对点的Queue  -->

    </bean>
    <!--  Spring提供的JMS工具类,他可以进行消息发送,接收等  -->
    <bean id="jsmTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="jmsFactory"/>
        <property name="defaultDestination" ref="destinationQueue"/>
        <property name="messageConverter">
            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>
</beans>

7.3、队列消息生产者

@Service
public class SpringMQ_Produce {
    
    

    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
    
    
        ApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        SpringMQ_Produce produce = (SpringMQ_Produce) context.getBean("springMQ_Produce");
        produce.jmsTemplate.send((session) -> {
    
    
            TextMessage textMessage = session.createTextMessage("spring和ActiveMQ的整合");
            return textMessage;
        });
        System.out.println("消息发送完毕！");
    }
}

7.4、队列消息消费者

@Service
public class SpringMQ_Consumer {
    
    
    @Autowired
    private JmsTemplate jmsTemplate;
    public static void main(String[] args) {
    
    
        ApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        SpringMQ_Consumer consumer = (SpringMQ_Consumer) context.getBean("springMQ_Consumer");
        String value = (String) consumer.jmsTemplate.receiveAndConvert();
        System.out.println("消费者收到的消息：" + value);
    }
}

7.5、主题生产者和消费者

7.6、消费者的监听器

<!--配置监听程序-->
<bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
    <property name="connectionFactory" ref="jmsFactory"/>
    <property name="destination" ref="destinationTopic"/>
    <property name="messageListener" ref="myMessageListener"/>
</bean>

@Component
public class MyMessageListener implements MessageListener {
    
    
    @Override
    public void onMessage(Message message) {
    
    
        if (message != null && message instanceof TextMessage) {
    
    
            TextMessage textMessage = (TextMessage) message;
            try {
    
    
                System.out.println(((TextMessage) message).getText());
            } catch (JMSException e) {
    
    
                e.printStackTrace();
            }
        }
    }
}

8、SpringBoot 整合 ActiveMQ

8.1、pom.xml添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
    <version>2.3.5.RELEASE</version>
</dependency>

8.2、application.yml

server:
  port: 7777

spring:
  activemq:
    broker-url: tcp://192.168.5.130:61616
    user: admin
    password: admin
  jms:
    pub-sub-domain: false  # 目的地是queue还是topic，false（默认） = queue    true =  topic

myqueue: boot-activemq-queue  #  自定义队列名称。这只是个常量

8.3、加入消息队列组件

@Configuration
public class ActivemqConfig {
    
    
    @Value("${myqueue}")
    private String myQueue;

    @Bean
    public Queue queue() {
    
    
        return new ActiveMQQueue(myQueue);
    }
}

8.4、队列生产者

@Component
public class Queue_Produce {
    
    
    @Autowired      
    private JmsMessagingTemplate jmsMessagingTemplate;   // JMS模板  

    @Autowired
    private Queue queue;     // 这个是我们配置的队列目的地

    public void produceMsg() {
    
    
        jmsMessagingTemplate.convertAndSend(queue, "发送的消息：" + UUID.randomUUID().toString().substring(0, 6));
    }
    // 间隔时间3s定投
    @Scheduled(fixedDelay = 3000)
    public void produceMsgScheduled() {
    
    
        jmsMessagingTemplate.convertAndSend(queue, "定时发送的消息：" + UUID.randomUUID().toString().substring(0, 6));
        System.out.println("定时发送消息完毕！");
    }
}

8.5、单元测试

@SpringBootTest
class ActivemqApplicationTests {
    
    

	@Resource      //  这个是java 的注解，而Autowried 是 spring 的
	private Queue_Produce queue_produce;
	@Test
	void contextLoads() {
    
    
		queue_produce.produceMsg();
	}

}

8.6、队列消费者

注册一个消息监听器。项目开启后监听某个主题的消息。

@Component
public class Queue_Consumer {
    
    

    // 注册一个监听器。destination指定监听的主题。
    @JmsListener(destination = "${myqueue}")
    public void receive(TextMessage textMessage) throws JMSException {
    
    
        System.out.println("消费者收到消息：" + textMessage.getText());
    }
}

8.7、topic 生产者和消费者

1、 application.yml

server:
  port: 6666

spring:
  activemq:
    broker-url: tcp://192.168.5.130:61616
    user: admin
    password: admin
  jms:
    pub-sub-domain: true  # 目的地是queue还是topic， false（默认） = queue    true =  topic

mytopic: boot-activemq-topic  #  自定义队列名称。这只是个常量

2、配置目的地的 bean 和 开启 JMS 功能

@Configuration
@EnableScheduling
public class ActivemqConfig {
    
    

    @Value("${mytopic}")
    private String topicName;

    @Bean
    public Topic topic() {
    
    
        return new ActiveMQTopic(topicName);
    }
}

3、生产者代码

@Component
public class Topic_Produce {
    
    
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;
    @Autowired
    private Topic topic;

    @Scheduled(fixedDelay = 3000)
    public void produceTopic() {
    
    
        jmsMessagingTemplate.convertAndSend(topic, "主题消息：" + UUID.randomUUID().toString().substring(0,6));
    }
}

4、消费者代码

@Component
public class Topic_Consumer {
    
    

    @JmsListener(destination = "${mytopic}")
    public void receive(TextMessage textMessage) throws JMSException {
    
    
        System.out.println("消费者收到的订阅消息：" + textMessage.getText());
    }
}
