SpringBoot整合RabbitMQ

SpringBoot整合RabbitMQ

创建一个新工程-生产者

1>改Pom

<!--
        1. 父工程依赖
    -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
    </parent>

    <dependencies>
        <!--2. rabbitmq-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
    </dependencies>

2>写yml

# 配置RabbitMQ的基本信息  ip 端口 username  password..
spring:
  rabbitmq:
    host: 10.167.237.111 # ip
    port: 5672
    username: guest
    password: guest
    virtual-host: /

3>启动类

package com.leavscai7.rabbitmq;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @Author: LeavesCai7
 * @Date: 2021/01/25 15:15
 */
@SpringBootApplication
public class ProducerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProducerApplication.class);
    }
}

4>配置类
1、交换机
2、Queue 队列
3、队列和交换机绑定关系 Binding

package com.leavscai7.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;

/**
 * @Author: LeavesCai7
 * @Date: 2021/01/25 15:16
 */
@Configuration
public class RabbitMQConfig {

    public static final String EXCHANGE_NAME = "boot_topic_exchange";
    public static final String QUEUE_NAME = "boot_queue";

    //1.交换机
    @Bean("bootExchange")
    public Exchange bootExchange(){
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();
    }

    //2.Queue 队列
    @Bean("bootQueue")
    public Queue bootQueue(){
        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){
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }
}

5>测试类

import com.leavescai7.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(){

        rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME,"boot.haha","boot mq hello~~~");
    }
}
