三，java代码说明

1,config/TopicConfig.java

@Configuration
public class TopicConfig {
    public static final String TOPIC_QUEUE1 = "topic.queue1";
    public static final String TOPIC_QUEUE2 = "topic.queue2";
    public static final String TOPIC_EXCHANGE = "topic.exchange";

    @Profile("dev")
    @Bean
    ConnectionFactory connectionFactory() {
        return new CachingConnectionFactory(MockConnectionFactoryFactory.build());
    }

    @Bean
    public Queue topicQueue1() {
        return new Queue(TOPIC_QUEUE1);
    }
    @Bean
    public Queue topicQueue2() {
        return new Queue(TOPIC_QUEUE2);
    }
    @Bean
    public TopicExchange topicExchange() {
        return new TopicExchange(TOPIC_EXCHANGE);
    }
    @Bean
    public Binding topicBinding1() {
        return BindingBuilder.bind(topicQueue1()).to(topicExchange()).with("topic.messge");
    }
    @Bean
    public Binding topicBinding2() {
        //#表示0个或多个word
        return BindingBuilder.bind(topicQueue2()).to(topicExchange()).with("topic.#");
    }
}

 

2,pojo/Goods.java

public class Goods implements Serializable {
    
    private static final long serialVersionUID = 6629065135155452917L;

    private Long goodsId;
    private String goodsName;
    private Double goodsPrice;

    public Long getGoodsId() {
        return goodsId;
    }

    public void setGoodsId(Long goodsId) {
        this.goodsId = goodsId;
    }

    public String getGoodsName() {
        return goodsName;
    }

    public void setGoodsName(String goodsName) {
        this.goodsName = goodsName;
    }

    public Double getGoodsPrice() {
        return goodsPrice;
    }

    public void setGoodsPrice(Double goodsPrice) {
        this.goodsPrice = goodsPrice;
    }

    public Goods(Long goodsId, String goodsName, Double goodsPrice) {
        this.goodsId = goodsId;
        this.goodsName = goodsName;
        this.goodsPrice = goodsPrice;
    }

    public Goods() {
    }

    @Override
    public String toString() {
        return "Goods{" +
                "goodsId=" + goodsId +
                ", goodsName='" + goodsName + '\'' +
                ", goodsPrice=" + goodsPrice +
                '}';
    }
}

 

3,receiver/TopicReceiver.java

@Component
public class TopicReceiver {
    @RabbitListener(queues = TopicConfig.TOPIC_QUEUE1)
    public void receiveTopic1(Goods goods) {
        System.out.println("receiveTopic1收到消息：" + goods.toString());
    }

    @RabbitListener(queues = TopicConfig.TOPIC_QUEUE2)
    public void receiveTopic2(Goods goods) {
        System.out.println("receiveTopic2收到消息：" + goods.toString());
    }
}

 

4,sender/TopicSender.java

@Component
public class TopicSender {
    //private static final Logger log = LoggerFactory.getLogger(TopicSender.class);
    @Autowired
    private AmqpTemplate amqpTemplate;

    public void sendTopicQueue() {
        Goods goods1 = new Goods(1L,"测试商品1",98.6);
        Goods goods2 = new Goods(2L,"测试商品2",100.0);
        System.out.println("TopicSender已发送消息");
        // 第一个参数：TopicExchange名字
        // 第二个参数：Route-Key
        // 第三个参数：要发送的内容
        this.amqpTemplate.convertAndSend(TopicConfig.TOPIC_EXCHANGE, "topic.messge", goods1 );
        this.amqpTemplate.convertAndSend(TopicConfig.TOPIC_EXCHANGE, "topic.messge2", goods2);
    }
}

 

5,module/RabbitmqMockerTest.java

@SpringBootTest
@ActiveProfiles("dev")
public class RabbitmqMockerTest {

    @Autowired
    AmqpTemplate amqpTemplate;

    @Autowired
    private TopicSender topicSender;

    @Test
    @DisplayName("测试发送消息")
    public void testSend() {
        topicSender.sendTopicQueue();
    }

    @Test
    @DisplayName("测试接收消息")
    public void testReceive() {
        Goods goods3 = new Goods(3L,"测试商品3",198.6);
        this.amqpTemplate.convertAndSend(TopicConfig.TOPIC_EXCHANGE, "topic.messge", goods3 );
        Goods goods = (Goods)amqpTemplate.receiveAndConvert("topic.queue1");
        System.out.println("goods begin");
        System.out.println(goods);
        assertThat(goods.getGoodsId(), equalTo(3L));
    }

}

 

四，测试效果

五，查看spring boot版本:
