rabbitMQ发送消息的代码：ProducerTest.java

package org.example;

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.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring-rabbitmq-producer.xml")
public class ProducerTest {

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

    /**
     * 测试rabbitMQ的简单工作模式
     */
    @Test
    public void testHelloWorld(){
        //2.发送消息
        rabbitTemplate.convertAndSend("spring_queue","hello world spring ....");
    }

    @Test
    public void testFanout(){
        //2.发送消息
        rabbitTemplate.convertAndSend("spring_fanout_exchange","","spring fanout ....");
    }

    @Test
    public void testTopic(){
        //2.发送消息
        rabbitTemplate.convertAndSend("spring_topic_exchange","heima.hehe.haha","spring topic ....");
    }
}

3.创建工程RabbitMQ Consumers

RabbitMQ consumer的pom文件和spring-rabbitmq-consumers项目的pom文件一致

RabbitMQ Consumer的配置文件：rabbitmq.properties和spring-rabbitmq-consumers项目的rabbitmq.properties文件一致

RabbitMQ Consumer的配置文件：spring-rabbitmq-consumer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:rabbit="http://www.springframework.org/schema/rabbit"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/rabbit
        http://www.springframework.org/schema/rabbit/spring-rabbit.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd

        ">

    <!-- 加载属性文件 此种方式加载属性文件是给spring的配置文件使用的 -->
    <context:property-placeholder
            location="classpath:rabbitmq.properties"/>
    <!--定义rabbitmq connectionFactory-->
    <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}"
                               port="${rabbitmq.port}"
                               username="${rabbitmq.username}"
                               password="${rabbitmq.password}"
                               virtual-host="${rabbitmq.virtual-host}" />

    <!--定义监听器-->
    <bean id="springQueueListener" class="org.example.listener.SpringQueueListener"/>
    <bean id="fanoutListListener1" class="org.example.listener.FanoutListListener1"/>
    <bean id="fanoutListListener2" class="org.example.listener.FanoutListListener2"/>
    <bean id="topicListListenerStar" class="org.example.listener.TopicListListenerStar"/>
    <bean id="topicListListenerWell" class="org.example.listener.TopicListListenerWell"/>
    <bean id="topicListListenerWell2" class="org.example.listener.TopicListListenerWell2"/>

    <!--注册监听器容器-->
    <rabbit:listener-container connection-factory="connectionFactory" auto-declare="true">
        <rabbit:listener ref="springQueueListener" queue-names="spring_queue"/>
        <rabbit:listener ref="fanoutListListener1" queue-names="spring_fanout_queue_1"/>
        <rabbit:listener ref="fanoutListListener2" queue-names="spring_fanout_queue_2"/>
        <rabbit:listener ref="topicListListenerStar" queue-names="spring_topic_queue_star"/>
        <rabbit:listener ref="topicListListenerWell" queue-names="spring_topic_queue_well"/>
        <rabbit:listener ref="topicListListenerWell2" queue-names="spring_topic_queue_well2"/>
    </rabbit:listener-container>

    <!--定义rabbitTemplate对象操作可以在代码中方便发送消息-->
    <rabbit:template id="rabbitTemplate" connection-factory="connectionFactory"/>
</beans>

编写Listener代码

package org.example.listener;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;

public class SpringQueueListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        //打印消息
        System.out.println(new String(message.getBody()));
    }
}

监听器在配置文件绑定了对应的队列，当消费者启动起来的时候，监听到消息时，自动消费并打印。

ConsumerTest.java

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring-rabbitmq-consumer.xml")
public class ConsumerTest {


    @Test
    public void test1() throws InterruptedException {
        Thread.sleep(5000);

    }
}

4.SpringBoot整合RabbitMQ

生产者

1.创建生产者SpringBoot工程

2.引入依赖

3.编写yml配置，基本信息配置

4.定义交换机，队列及绑定关系的配置类

5.注入RabbitTemplate，调用方法，完成消息发送
消费者

1.创建消费者SpringBoot工程

2.引入依赖

3.编写yml配置，基本信息配置

4.定义监听类，使用@RabbitListener注解完成队列监听

总结：

  1. springboot提供了快速整合RabbitMQ的方式
  2. 基本信息在yml中配置，队列、交换机及绑定关系在配置类中使用Bean的方式配置
  3. 生产端直接注入RabbitTemplate完成消息发送
  4. 消费端直接使用@RabbitListener完成消息接收

5.创建SpringBoot RabbitMQ Producers

</project>

配置文件：application.yml

spring:
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
    virtual-host: /

配置类：RabbitMQConfig.java

package com.example.config;

import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Configurable;
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.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.绑定队列和交换机 Binding

    /**
     * 绑定
     * @param queue 知道绑定哪个队列
     * @param exchange 知道哪个交换机
     * routingKey 路由键
     * @return
     */
    @Bean
    public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue,@Qualifier("bootExchange") Exchange exchange) {
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }
}

测试方法

package com.example.test;

import com.example.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RabbitTemplage
    @Autowired
    private RabbitTemplate rabbitTemplate;
    
    @Test
    public void testSend(){
        rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME,"boot.haha","boot mq hello ~~~");
    }

}

6.创建SpringBoot RabbitMQ Consumers

配置文件：pom.xml和application.yml 和RabbitMQ Producer一样

Consumer的Listener 

package com.example.listener;

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

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

测试方法

package com.example.test;


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 ConsumerTest {

    @Test
    public void testReceive(){
        System.out.println("接收成功");
    }
}
