SpringBoot整合RabbitMQ（基础）

一.环境准备

1、在pom文件中引入对应的依赖：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

2、在application.yml配置文件中配置RabbitMQ:

spring:
    #rabbitmq配置
  rabbitmq:
    host: 192.168.150.152#rabbitMq的服务器地址
    port: 5672
    username: root #用户名
    password: 123456 #密码
    virtual-host: /hjl #虚拟主机

二、整合

点对点，简单模式

①配置文件中声明队列

@SpringBootConfiguration
public class RabbitMqConfig {
    
    
    /**
     * hello队列名称
     */
    public static final String HELLO_MSG_QUEUE = "hello.msg.queue";
   
    /**
     * 声明hello队列
     *
     * @return
     */
    @Bean
    public Queue getHelloQueue() {
    
    
    	//参数一：队列名；参数二：是否持久化队列
        return new Queue(HELLO_MSG_QUEUE, true);
    }


}

②创建生产者

@SpringBootTest
@RunWith(SpringRunner.class)
public class RabbitMqTest {
    
    
    @Resource
    private RabbitTemplate rabbitTemplate;
    @Test
    public void sendHello() {
    
    
        for (int i = 0; i < 10; i++) {
    
    
            rabbitTemplate.convertAndSend(RabbitMqConfig.HELLO_MSG_QUEUE, "hello world" + i);
        }
    }
}

消息发送成功后，在web管理页面查看：在这里插入图片描述
可以看到对应队列中产生了消息
③创建消费者

@Component
public class RabbitMqConsumer {
    
    
    @RabbitListener(queues = RabbitMqConfig.HELLO_MSG_QUEUE)
    public void listenHelloMsg(String message) {
    
    
        System.out.println("接受时间："+System.currentTimeMillis());
        System.out.println("转发消息是：" + message);
    }
}

启动项目，可以看到消息成功消费：
在这里插入图片描述

工作队列（多个消费者对应一个队列）

①声明队列

@SpringBootConfiguration
public class RabbitMqConfig {
    
    
    /**
     * work队列名称
     */
    public static final String WORK_MSG_QUEUE = "work.msg.queue";
    /**
     * 声明work队列
     *
     * @return
     */
    @Bean
    public Queue getWorkQueue() {
    
    
        //参数一：队列名；参数二：是否持久化队列
        return new Queue(WORK_MSG_QUEUE, true);
    }
}

②创建生产者

@SpringBootTest
@RunWith(SpringRunner.class)
public class WorkMqTest {
    
    
    @Resource
    private RabbitTemplate rabbitTemplate;

    @Test
    public void send() {
    
    
        for (int i = 0; i < 10; i++) {
    
    
            rabbitTemplate.convertAndSend(RabbitMqConfig.WORK_MSG_QUEUE, "这是一条工作队列消息" + i);
        }
    }
}

③创建消费者（多个）

@Component
public class RabbitMqConsumer {
    
    
    @RabbitListener(queues = RabbitMqConfig.WORK_MSG_QUEUE)
    public void listenWork1(String message) {
    
    
        System.out.println("消费者一转发消息是：" + message);
    }
    @RabbitListener(queues = RabbitMqConfig.WORK_MSG_QUEUE)
    public void listenWork2(String message) {
    
    
        System.out.println("消费者二转发消息是：" + message);
    }
}

在这里插入图片描述
可以看到两个消费者都成功消费量word队列中的消息

发布订阅模式

①声明队列，交换机并绑定


@SpringBootConfiguration
public class RabbitMqConfig {
    
    
   /**
     * publish队列1
     */
    public static final String PUBLISH_MSG_QUEUE1 = "publish.msg.queue1";
    /**
     * publish队列2
     */
    public static final String PUBLISH_MSG_QUEUE2 = "publish.msg.queue2";
    /**
     * publish交换机
     */
    public static final String PUBLISH_EXCHANGE = "publish.exchange";

   
    /**
     * Publish队列
     *
     * @return
     */
    @Bean
    public Queue getPublishQueue1() {
    
    
        return new Queue(PUBLISH_MSG_QUEUE1, true);
    }
    /**
     * Publish队列
     *
     * @return
     */
    @Bean
    public Queue getPublishQueue2() {
    
    
        return new Queue(PUBLISH_MSG_QUEUE2, true);
    }
    /**
     * Publish交换机
     *
     * @return
     */
    @Bean
    public FanoutExchange publishExchange() {
    
    
        FanoutExchange exchange = new FanoutExchange(PUBLISH_EXCHANGE, true, false);
        return exchange;
    }

    /**
     * 绑定队列和交换机
     *
     * @return
     */
    @Bean
    public Binding bindPublishExchangeQueue1() {
    
    
        Binding binding = BindingBuilder.bind(getPublishQueue1()).to(publishExchange());
        return binding;
    }
    /**
     * 绑定队列和交换机
     *
     * @return
     */
    @Bean
    public Binding bindPublishExchangeQueue2() {
    
    
        Binding binding = BindingBuilder.bind(getPublishQueue2()).to(publishExchange());
        return binding;
    }

②创建生产者

@SpringBootTest
@RunWith(SpringRunner.class)
public class PublishMqTest {
    
    
    @Resource
    private RabbitTemplate rabbitTemplate;

    @Test
    public void send() {
    
    
        for (int i = 0; i < 10; i++) {
    
    
            //参数一：交换机名称;参数二:routingKey(广播模式不传)；参数三：消息体
            rabbitTemplate.convertAndSend(RabbitMqConfig.PUBLISH_EXCHANGE, null, "这是一条工作队列消息" + i);
        }
    }
}

③创建消费者（多个）

@Component
public class PublishConsumer {
    
    
    @RabbitListener(queues = RabbitMqConfig.PUBLISH_MSG_QUEUE1)
    public void listenDead1(String message) {
    
    
        System.out.println("消费者一接收消息：" + message);
    }
    @RabbitListener(queues = RabbitMqConfig.PUBLISH_MSG_QUEUE2)
    public void listenDead2(String message) {
    
    
        System.out.println("消费者二接收消息：" + message);
    }
}

在这里插入图片描述
可以看到两个消费之都接收了生产者所有的消息；与工作队列不同的是，工作队列的消费者只消费部分消息，而此模式是消费所有。

路由模式

在这里插入图片描述
①声明队列


@SpringBootConfiguration
public class RabbitMqConfig {
    
    
   
    /**
     * routing交换机
     */
    public static final String ROUTING_EXCHANGE = "routing.exchange";
    /**
     * routing队列1
     */
    public static final String ROUTING_MSG_QUEUE1 = "routing.msg.queue1";
    /**
     * routing队列2
     */
    public static final String ROUTING_MSG_QUEUE2 = "routing.msg.queue2";

    /**
     * routing队列
     *
     * @return
     */
    @Bean
    public Queue getRoutingQueue1() {
    
    
        return new Queue(ROUTING_MSG_QUEUE1, true);
    }

    /**
     * routing队列
     *
     * @return
     */
    @Bean
    public Queue getRoutingQueue2() {
    
    
        return new Queue(ROUTING_MSG_QUEUE2, true);
    }

    /**
     * Publish交换机
     *
     * @return
     */
    @Bean
    public DirectExchange routingExchange() {
    
    
        DirectExchange exchange = new DirectExchange(ROUTING_EXCHANGE, true, false);
        return exchange;
    }

    /**
     * 绑定队列和交换机
     *
     * @return
     */
    @Bean
    public Binding bindRoutingExchangeQueue1() {
    
    
        Binding binding = BindingBuilder.bind(getRoutingQueue1()).to(routingExchange()).with("routingKey1");
        return binding;
    }

    /**
     * 绑定队列和交换机
     *
     * @return
     */
    @Bean
    public Binding bindRoutingExchangeQueue2() {
    
    
        Binding binding = BindingBuilder.bind(getRoutingQueue2()).to(routingExchange()).with("routingKey2");
        return binding;
    }
}

②创建生产者

@SpringBootTest
@RunWith(SpringRunner.class)
public class RoutingMqTest {
    
    
    @Resource
    private RabbitTemplate rabbitTemplate;

    @Test
    public void send() {
    
    
            //参数一：交换机名称;参数二:routingKey（交换机与队列绑定的key）；参数三：消息体
            rabbitTemplate.convertAndSend(RabbitMqConfig.ROUTING_EXCHANGE, "routingKey1", "队列一：这是一条路由消息消息");
            rabbitTemplate.convertAndSend(RabbitMqConfig.ROUTING_EXCHANGE, "routingKey2", "队列二：这是一条路由消息消息");
    }
}

③创建消费者

@Component
public class RoutingConsumer {
    
    
    @RabbitListener(queues = RabbitMqConfig.ROUTING_MSG_QUEUE1)
    public void listenDead1(String message) {
    
    
        System.out.println("消费者一接收消息：" + message);
    }

    @RabbitListener(queues = RabbitMqConfig.ROUTING_MSG_QUEUE2)
    public void listenDead2(String message) {
    
    
        System.out.println("消费者二接收消息：" + message);
    }
}

运行结果：
在这里插入图片描述
x显而易见：与发布订阅模式不同的是，此模式需要将交换机与队列通过routingKey绑定，并且生产者可以通过指定routingKey,可以将消息发送到指定队列中

通配符模式

①声明队列，交换机


@SpringBootConfiguration
public class RabbitConfig {
    
    

    /**
     * topic交换机
     */
    public static final String TOPIC_EXCHANGE = "topic.exchange";
    /**
     * topic队列1
     */
    public static final String TOPIC_MSG_QUEUE1 = "topic.msg.queue1";
    /**
     *topic队列2
     */
    public static final String TOPIC_MSG_QUEUE2 = "topic.msg.queue2";

    /**
     * routing队列
     *
     * @return
     */
    @Bean
    public Queue getTopicQueue1() {
    
    
        return new Queue(TOPIC_MSG_QUEUE1, true);
    }
    /**
     * routing队列
     *
     * @return
     */
    @Bean
    public Queue getTopicQueue2() {
    
    
        return new Queue(TOPIC_MSG_QUEUE2, true);
    }
    /**
     * Publish交换机
     *
     * @return
     */
    @Bean
    public TopicExchange topIcExchange() {
    
    
        TopicExchange exchange = new TopicExchange(TOPIC_EXCHANGE, true, false);
        return exchange;
    }

    /**
     * 绑定队列和交换机
     *
     * @return
     */
    @Bean
    public Binding bindTopicExchangeQueue1() {
    
    
        Binding binding = BindingBuilder.bind(getTopicQueue1()).to(topIcExchange()).with("topKey.*");
        return binding;
    }
    /**
     * 绑定队列和交换机
     *
     * @return
     */
    @Bean
    public Binding bindTopicExchangeQueue2() {
    
    
        Binding binding = BindingBuilder.bind(getTopicQueue2()).to(topIcExchange()).with("topKey.#");
        return binding;
    }
}

②创建生产者

@SpringBootTest
@RunWith(SpringRunner.class)
public class TopicMqTest {
    
    
    @Resource
    private RabbitTemplate rabbitTemplate;

    @Test
    public void send() {
    
    
        //参数一：交换机名称;参数二:routingKey(广播模式不传)；参数三：消息体
        rabbitTemplate.convertAndSend(RabbitConfig.TOPIC_EXCHANGE, "topic.key1", "这是一条通配符模式消息一");
        rabbitTemplate.convertAndSend(RabbitConfig.TOPIC_EXCHANGE, "topic.key1.key2", "这是一条通配符模式消息二");
    }
}

③创建消费者

@Component
public class TopicConsumer {
    
    
    @RabbitListener(queues = RabbitConfig.TOPIC_MSG_QUEUE1)
    public void listenDead1(String message) {
    
    
        System.out.println("消费者一接收消息：" + message);
    }

    @RabbitListener(queues = RabbitConfig.TOPIC_MSG_QUEUE2)
    public void listenDead2(String message) {
    
    
        System.out.println("消费者二接收消息：" + message);
    }
}

运行结果如下：
在这里插入图片描述
可以看到：与路由模式不同的是topic支持通配符模式的路由key；特别的是"*“只能代替一个单词；而”#"可以代替多个；
