SpringBoot 整合ActiveMQ

队列 - 生产者

1）新建Maven工程

2）引入依赖

            </plugin>
        </plugins>
    </build>

</project>

3）springboot启动类

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

4）编写 application.yml

server:
  port: 7777

spring:
  activemq:
    broker-url: tcp://192.168.2.180:61616 #MQ服务器地址
    user: admin
    password: admin
  jms:
    pub-sub-domain: false #false = queue   true = topic

# 自己定义队列名称
myqueue: boot-activemq-queue

5）配置bean，向ioc容器中注入一个队列，并开启jms

@Configuration
@EnableJms  //
public class ConfigBean {

    @Value("${myqueue}")
    private String myQueue;

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

6）编写Queue_Produce，并注入到ioc容器

@Component
public class Queue_Produce {

 //SpringBoot已经自动将JmsMessagingTemplate注册到ioc容器中
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Queue queue;

    public void produceMsg(){
        jmsMessagingTemplate.convertAndSend(queue,
                "***"+ UUID.randomUUID().toString().substring(0, 6));
        System.out.println("消息推送到MQ成功");
    }
}

7）测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class TestActiveMq {

    @Autowired
    private Queue_Produce produce;

    @Test
    public void test(){
        produce.produceMsg();
    }
}

补充：生产者间隔定投

//Queue_Produce类中加如下方法
@Scheduled(fixedDelay=3000)  //三秒钟定时投递一次
public void produceMsgSchedule(){
    jmsMessagingTemplate.convertAndSend(queue,
            "***"+ UUID.randomUUID().toString().substring(0, 6));
    System.out.println("消息推送到MQ成功");
}

// 主配置类中加如下注解
@EnableScheduling

队列 - 消费者

1）新建maven工程

2）引入pom文件（同上）

3）SpringBoot启动类

@SpringBootApplication
public class MainApp_Consumer {
    public static void main(String[] args) {
        SpringApplication.run(MainApp_Consumer.class,args);
    }
}

4）配置文件 application.xml

server:
  port: 7777

spring:
  activemq:
    broker-url: tcp://192.168.2.180:61616 #MQ服务器地址
    user: admin
    password: admin
  jms:
    pub-sub-domain: false #表示本次目的地是队列还是主题  false = queue   true = topic

# 自己定义队列名称
myqueue: boot-activemq-queue

5） Queue_Consumer

@Component
public class Queue_Consumer {

    @JmsListener(destination = "${myqueue}")
    public void receive(TextMessage textMessage) throws JMSException {
        System.out.println("消费者接收到消息"+textMessage.getText());

    }
}

启动消费者
