SpringBoot 整合 RabbitMQ

生产者

1、创建生产者SpringBoot工程

2、引入starter依赖

<!-- rabbitmq依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

3、yml配置 基本信息

spring:
  rabbitmq:
    host: 121.40.241.131 #ip 默认：localhost
    port: 5672 #默认
    username: admin
    password: 123
    virtual-host: /

4、定义交换机、队列以及绑定关系的配置类

package com.wyk.rabbitmq.producer.config;


import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class RabbitMQConfig {

	public static final String EXCHANGE_NAME = "boot_topic_exchange";
	public static final String QUEUE_NAME1 = "boot_queue1";
	public static final String QUEUE_NAME2 = "boot_queue2";

	// Exchange 交换机
	@Bean
	public Exchange bootExchange(){
		return ExchangeBuilder
				.topicExchange(EXCHANGE_NAME).durable(true).build();
	}

	// Queue队列
	@Bean
	public Queue bootQueue(){
		return QueueBuilder.durable(QUEUE_NAME1).build();
	}

	@Bean
	public Queue bootQueue1(){
		return QueueBuilder.durable(QUEUE_NAME2).build();
	}

	// 队列与交换机的绑定关系
	@Bean
	public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue,@Qualifier("bootExchange")Exchange exchange){
		return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
	}

	// 队列与交换机的绑定关系
	@Bean
	public Binding bindQueue1Exchange(@Qualifier("bootQueue1") Queue queue,@Qualifier("bootExchange")Exchange exchange){
		return BindingBuilder.bind(queue).to(exchange).with("*.*").noargs();
	}

}

5、注入RabbitTemplate，调用方法，完成消息发送

package com.wyk.rabbitmq.producer;

import com.wyk.rabbitmq.producer.config.RabbitMQConfig;
import org.junit.jupiter.api.Test;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class SpringbootRabbitmqProducerApplicationTests {

	@Autowired
	private RabbitTemplate rabbitTemplate;

	@Test
	void testSend() {
		rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME,"boot.abc","message rabbitmq SpringBoot");
	}

}

消费者

定义监听器，使用@RabbitListenter注解完成队列监听

package com.wyk.springbootrabbitmq.consumer;


import com.wyk.springbootrabbitmq.config.RabbitMQConfig;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
public class RabbitMQListener {

	@RabbitListener(queues = RabbitMQConfig.QUEUE_NAME1)
	public void listenerQueue(Message message){
		System.out.println(new String(message.getBody()));
	}
}
