springboot整合rabbitmq

1.依赖

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

2. 配置

spring:
  rabbitmq:
    host: localhost
    port: 5672
    virtual-host: /bgt
    username: bgt
    password: 111111

3.配置类

配置交换机和队列,及绑定交换机和队列.

package com.rabbitmq.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_NAME = "boot_queue";

    //1.创建交换机
    @Bean("bootExchange")
    public Exchange bootExchange(){
        //                      通配符模式       交换机名称       持久化
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();
    }


    //2.Queue 队列
    @Bean("bootQueue")
    public Queue bootQueue(){
        //                      持久化
        return QueueBuilder.durable(QUEUE_NAME).build();
    }

    //3. 队列和交互机绑定关系 Binding
    /*
        1. 知道哪个队列
        2. 知道哪个交换机
        3. routing key
     */
    @Bean
    public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue, @Qualifier("bootExchange") Exchange exchange){
        //                  绑定队列        到指定交换机   指定路由key                无参数
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }

}

4.测试生产者发送消息

package com.test;


import com.itheima.rabbitmq.config.RabbitMQConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest
@RunWith(SpringRunner.class)
public class ProducerTest {

    //1.注入RabbitTemplate
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void testSend(){
        //2.测试发送
        rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME,"boot.haha","boot mq hello~~~");
    }
}

5.消费者监听消息

消费者依赖和配置文件和生产者相同

package com.consumerspringboot;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
public class RabbimtMQListener {

    @RabbitListener(queues = "boot_queue")
    public void ListenerQueue(Message message){
        //System.out.println(message);
        System.out.println(new String(message.getBody()));
    }

}
