生產者代碼，主題交換機

主題交換機的routKey是有通配符*和#的。

*代表必有一單詞，#代表0或多個單詞

單獨#代表必發

@Configuration
public class RabbitConfig {

    @Bean
    TopicExchange myTopicExchange(){
        return new TopicExchange("myTopicExchange");
    }

    @Bean

消費者，可以放到一個另一個項目裏面

 

@Service
public class DirectReceiver {

    @RabbitHandler
    @RabbitListener(queues = "myque1")
    public void process1(String testMessage) {
        System.out.println("myque1消費者收到消息  : " + testMessage.toString());
    }

    @RabbitHandler
    @RabbitListener(queues = "myque2")
    public void process2(String testMessage) {
        System.out.println("myque2消費者收到消息  : " + testMessage.toString());
    }

    @RabbitHandler
    @RabbitListener(queues = "myque3")
    public void process3(String testMessage) {
        System.out.println("myque3消費者收到消息  : " + testMessage.toString());
    }

    @RabbitHandler
    @RabbitListener(queues = "myque4")
    public void process4(String testMessage) {
        System.out.println("myque4消費者收到消息  : " + testMessage.toString());
    }
}
