Rabbitmq中綁定
exchange:flow
routing-key:user
bind-queue:flow_user
白話文就是,把user綁定到flow_user序列
發送方使用routing-key推送：
//把routing-key發送給名為flow的exchenge，然后exchenge負責向綁定的這個Queue推送
amqpTemplate.convertAndSend("flow","user", context);
Rabbit配置
- 添加exchange（這里類型type應該是topic,截圖時候沒有注意）
添加exchange
- 添加Queue
添加Queue
- 添加這個User 到exchange(注意routing-key)
SpringBoot集成Rabbitmq
- 注冊配置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);
}
}
