导入RabbitMQ依赖

pom.xml

<!--AMQP依赖，包含RabbitMQ-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

 

提供者和消费者的配置

application.yml

spring:
  rabbitmq:
    host: 192.168.137.139 # 主机名
    port: 5672 # 端口
    virtual-host: / # 虚拟主机
    username: admin # 用户名
    password: admin # 密码

 

注意执行顺序：需要先使用consumer监听并创建队列，publisher再往里面添加队列才会有用，否则白添加队列

SimpleQueue

提供者: SimpleQueuePublisher.java

@RunWith(SpringRunner.class)
@SpringBootTest
public class SimpleQueuePublisher {
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void simpleQueueTest() {
        String msg = "hello, simple queue";
        rabbitTemplate.convertAndSend("simple.queue", msg);
    }
}

消费者：SimpleQueueConsumer.java

@Component
public class SimpleQueueConsumer {
    @RabbitListener(queues = "simple.queue")
    public void simpleQueueConsumer(String msg) {
        System.out.println("simpleQueueConsumer: " + msg);
    }
}

Work Queues

可加配置

application.yml

spring:
  rabbitmq:
    listener:
      simple: # simple类型
        prefetch: 1 # consumer每次执行预取的数量

消费者：WorkQueueConsumer.java

@Component
public class WorkQueueConsumer {
    @RabbitListener(queuesToDeclare = {@Queue(name = "work.queue")})
    public void workQueue1Consumer(String msg) throws InterruptedException {
        System.out.println("workQueue1Consumer: " + msg);
        Thread.sleep(10);
    }

    @RabbitListener(queuesToDeclare = {@Queue(name = "work.queue")})
    public void workQueue2Consumer(String msg) throws InterruptedException {
        System.out.println("workQueue2Consumer: " + msg);
        Thread.sleep(90);
    }
}

提供者: WorkQueuePublisher.java

@RunWith(SpringRunner.class)
@SpringBootTest
public class WorkQueuePublisher {
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void workQueueTest() {
        for (int i = 1; i <= 100; i ++ ) {
            String msg = "hello, work queue. " + i;
            rabbitTemplate.convertAndSend("work.queue", msg);
        }
    }
}
