SpringBoot集成Rabbit使用TopicRabbit指

Rabbitmq中绑定

exchange:flow

routing-key:user

bind-queue:flow_user

白话文就是,把user绑定到flow_user序列

发送方使用routing-key推送：

//把routing-key发送给名为flow的exchenge，然后exchenge负责向绑定的这个Queue推送
 amqpTemplate.convertAndSend("flow","user", context);

Rabbit配置

• 添加exchange（这里类型type应该是topic,截图时候没有注意）

添加exchange

• 添加Queue

添加Queue

• 添加这个User 到exchange(注意routing-key)

SpringBoot集成Rabbitmq

• 注册配置bean

@Configurable
public class TopicRabbitConfig {
    public final static String FLOW = "flow";
    
    public final static String USER = "user";
    public final static String USER_QUEUE = "flow_user";

   
    @Bean
    public Queue queueMessages3() {
        return new Queue(USER_QUEUE);
    }

    @Bean
    TopicExchange exchange() {
        return new TopicExchange(FLOW);
    }
    @Bean
    Binding bindingExchangeMessages3(Queue queueMessages3, TopicExchange exchange) {
        return BindingBuilder.bind(queueMessages3).to(exchange).with(FLOW);
    }
}
