SpringBoot整合RabbitMQ
1.maven 依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId><version>2.7.5</version>
</dependency>2.添加配置文件
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest3.添加配置文件
package com.label.config;import org.springframework.amqp.core.*;import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;/*** @author sszdzq*/
@Component
public class RabbitMqConfig {/*** 定义一个主题类型的交换机** @return*/@Bean("topic-exchange")public Exchange topicExchange() {return ExchangeBuilder.topicExchange("topic-exchange") // 交换机类型，交换机名称.durable(true) //ture为持久化，存到磁盘，false存到内存.build();}/*** 定义一个队列** @return*/@Bean("messageQueue")public Queue messageQueue() {return new Queue("messageQueue");}/*** 交换机、队列、路由键 进行绑定** @param exchange //交换机* @param queue //队列* @return*/@Beanpublic Binding bindQueueAndExchange(@Qualifier("topic-exchange") Exchange exchange, @Qualifier("messageQueue") Queue queue) {return BindingBuilder.bind(queue).to(exchange).with("news.*") //路由键.noargs();}
}
4.创建生产者与消费者
