## 环境准备 ##

*  启动的ActiveMQ服务
 *  JDK1.8+
 *  IDEA或Eclipse
 *  Maven环境
 *  SpringBoot和ActiveMQ整合的依赖

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-activemq</artifactId>
    </dependency>
    
    <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter</artifactId>
       <version>2.2.1.RELEASE</version>
    </dependency>
    <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    
    <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-test</artifactId>
       <scope>test</scope>
    </dependency>
    <dependency>
       <groupId>junit</groupId>
       <artifactId>junit</artifactId>
       <scope>test</scope>
    </dependency>

## 环境启动配置和代码 ##

application.yml配置：

server:
      port: 7777
    spring:
      activemq:
        #你的activemq连接地址
        broker-url: tcp://47.98.163.118:8161:61616
        #账号
        user: admin
        #密码
        password: admin
      jms:
        #指定连接的是队列(Queue)还是主题(Topic)，false代表队列,true代表主题
        pub-sub-domain: false
    
    queue:
      name: boot-queue-test
      
    topic:
      name: boot-topic-test

## ActiveMQ配置类： ##

package com.huazai.activemq.springboot.config;
    
    import org.apache.activemq.command.ActiveMQQueue;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import javax.jms.Queue;
    
    /**
     * @author pyh
     * @date 2021/1/16 19:13
     */
    @Configuration
    public class ActiveConfig {
        
        @Value("${queue.name}")
        private String queueName;
        
    	@Value("${topic.name}")
        private String topicName;
    
        @Bean
        public Queue activeQueue() {
        
            return new ActiveMQQueue(queueName);
        }
    
    	@Bean
        public Topic activeTopic() {
        
            return new ActiveMQTopic(topicName);
        }
    }

启动类：

package com.huazai.activemq.springboot;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.jms.annotation.EnableJms;
    
    /**
     * @author pyh
     * @date 2021/1/16 18:51
     */
    @SpringBootApplication
    // 开启JMS服务
    @EnableJms
    public class BootQueueProviderMain {
        
        public static void main(String[] args) {
        
            SpringApplication.run(BootQueueProviderMain.class, args);
        }
    }

## 队列生产者代码 ##

package com.huazai.activemq.springboot.queue;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jms.annotation.JmsListener;
    import org.springframework.jms.core.JmsMessagingTemplate;
    import org.springframework.jms.core.JmsTemplate;
    import org.springframework.stereotype.Service;
    
    import javax.jms.JMSException;
    import javax.jms.Queue;
    import java.util.UUID;
    
    @Service
    public class QueueProviderService {
        
        /**
         * 相当于 {@link JmsTemplate}
         */
        @Autowired
        private JmsMessagingTemplate jmsMessagingTemplate;
    
        @Autowired
        private Queue queue;
    
        /**
         * 生产消息
         *
         * @throws JMSException
         */
        @JmsListener(destination = "${queue.name}")
        public void productMessage() throws JMSException {
        
            // 生产者生产并发送消息，此方法是send方法的加强版
            jmsMessagingTemplate.convertAndSend(queue, "消费者发送消息：" + UUID.randomUUID());
        }
    }

队列消息发送测试类：

import com.huazai.activemq.springboot.BootQueueProviderMain;
    import com.huazai.activemq.springboot.queue.QueueProviderService;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    import javax.jms.JMSException;
    
    /**
     * @author pyh
     * @date 2021/1/16 19:25
     */
    @SpringBootTest(classes = BootQueueProviderMain.class)
    @RunWith(SpringJUnit4ClassRunner.class)
    public class QueueProviderTest {
        
        @Autowired
        private QueueProviderService queueProviderService;
    
        @Test
        public void testSend() throws JMSException {
        
            queueProviderService.productMessage();
        }
    }

启动测试类，将消息发送到名称为boot-queue-test队列，结果如下：

## 队列消费者代码 ##

消息监听消费服务：

package com.huazai.activemq.springboot.queue;
    
    
    import org.springframework.jms.annotation.JmsListener;
    import org.springframework.stereotype.Service;
    
    import javax.jms.JMSException;
    import javax.jms.TextMessage;
    
    @Service
    public class QueueConsumerService {
        
        /**
         * 监听接收的方法，监听的目的地名称为${queue.name}配置
         */
        @JmsListener(destination = "${queue.name}")
        public void receive(TextMessage textMessage) throws JMSException {
        
            String text = textMessage.getText();
            System.out.println("***消费者收到的消息:    " + text);
        }
    }

启动消费者服务，接受到了之前生产者生产的消息，测试结果如下：

## 定时任务发送消息 ##

1.  开启主启动类

@SpringBootApplication
    @EnableScheduling      // 是否开启
    public class MainApp_Produce {
        
        public static void main(String[] args) {
        
            SpringApplication.run(MainApp_Produce.class,args);
        }
    }

![在这里插入图片描述][20210306185227143.png]  
2. 使用注解@Scheduled

// 带定时投递的业务方法
        @Scheduled(fixedDelay = 3000)    // 每3秒自动调用
        public void produceMessageScheduled(){
        
            jmsMessagingTemplate.convertAndSend(queue,"** scheduled **"+ UUID.randomUUID().toString().substring(0,6));
            System.out.println("  produceMessage  send   ok   ");
        }

## 主题代码 ##

主题订阅者服务

package com.huazai.activemq.springboot.topic;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jms.core.JmsMessagingTemplate;
    import org.springframework.scheduling.annotation.Scheduled;
    import org.springframework.stereotype.Service;
    
    import javax.jms.Topic;
    import java.util.UUID;
    
    /**
     * @author pyh
     * @date 2021/1/17 15:14
     */
    @Service
    public class TopicProviderService {
        
        @Autowired
        private JmsMessagingTemplate jmsMessagingTemplate;
    
        @Autowired
        private Topic topic;
    
        /**
         * 每隔3秒定时发布主题消息
         */
        @Scheduled(fixedDelay = 3000)
        public void productTopic() {
        
            jmsMessagingTemplate.convertAndSend(topic, "发布者发布主题消息：" + UUID.randomUUID());
        }
    }

主题发布者服务

package com.huazai.activemq.springboot.topic;
    
    import org.springframework.jms.annotation.JmsListener;
    import org.springframework.stereotype.Service;
    
    import javax.jms.JMSException;
    import javax.jms.TextMessage;
    
    /**
     * @author pyh
     * @date 2021/1/17 15:15
     */
    @Service
    public class TopicConsumerService {
        
    
        /**
         * 开启监听器监听主题消息
         *
         * @param textMessage
         * @throws JMSException
         */
        @JmsListener(destination = "${topic.name}")
        public void receive(TextMessage textMessage) throws JMSException {
        
            String text = textMessage.getText();
            System.out.println("订阅者订阅到的消息：" + text);
        }
    }

先启动主题订阅者，再启动主题发布者，主题订阅者会间隔3秒接收到主题发布者的消息，结果如下：
