一、队列

1.1 队列生产者

1.1.1 pom.xml文件

依赖：

<dependencies>
    <!--springboot和activemq整合-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-activemq</artifactId>
        <version>2.5.3</version>
    </dependency>

    <dependency>

            </exclusion>
        </exclusions>
    </dependency>
</dependencies>

1.1.2 application.yml文件

# 端口
server:
  port: 8081

spring:
  activemq:
    broker-url: tcp://192.168.10.100:61616
    user: admin
    password: admin
  jms:
    pub-sub-domain: false     # false = queue(不写默认)    true = topic

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

1.1.3 配置Bean

@Component
@EnableJms  //开启jms注解
public class ConfigBean {

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

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

1.1.4 QueueProducer生产者

@Component
public class QueueProducer {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;
    @Autowired
    private Queue queue;

    public void produceMsg(){
        jmsMessagingTemplate.convertAndSend(queue,"***生产者："+ UUID.randomUUID().toString().substring(0,7));
    }
}

1.1.5 主启动类MainAppProducer

@SpringBootApplication
public class ActiveMq05SpringbootApplication {
    public static void main(String[] args) {
        SpringApplication.run(ActiveMq05SpringbootApplication.class, args);
    }
}

1.1.6 测试

@SpringBootTest(classes = ActiveMq05SpringbootApplication.class)
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class ActiveMq05SpringbootApplicationTests {

    @Resource    //  这个是java 的注解，而Autowried  是 spring 的
    private QueueProducer queue_produce ;

    @Test
    public  void testSend() throws Exception{
        queue_produce.produceMessage();
    }

}

1.1.7 新需求

每个3秒往MQ推送消息，以下定时发送Case，案列修改

• 修改QueueProducer，新增定时投递方法

@Component
public class QueueProducer {

    @Autowired
    private JmsMessagingTemplate  jmsMessagingTemplate ;

    @Autowired
    private Queue queue ;

    // 调用一次一个信息发出
    public void produceMessage(){
        jmsMessagingTemplate.convertAndSend(queue,"springboot-mq-生产者："+ UUID.randomUUID().toString().substring(0,6));
    }

    //间隔时间3秒定投
    @Scheduled(fixedDelay = 3000)
    public void produceMsgScheduled(){
        jmsMessagingTemplate.convertAndSend(queue,"定时发送："+UUID.randomUUID().toString().substring(0,6));
    }
}

• 修改主启动类

@SpringBootApplication
@EnableScheduling
public class ActiveMq05SpringbootApplication {
    public static void main(String[] args) {
        SpringApplication.run(ActiveMq05SpringbootApplication.class, args);
    }
}

• 直接开启主启动类，间隔发消息OK
