SpringBoot整合RabbitMQ生产者
1创建maven项目
2引入依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.2.RELEASE</version>
</parent>

<dependencies>
    <!-- spring的上下文 -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
    </dependency>

    <!-- spring整合amqp插件包 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </dependency>

    <!-- 单元测试包 -->

        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <scope>test</scope>
    </dependency>

</dependencies>

3创建 rabbitmq.properties 配置文件

rabbitmq.host=127.0.0.1
rabbitmq.port=5672
rabbitmq.username=guest
rabbitmq.password=guest
rabbitmq.virtual-host=/

4创建 spring-rabbitmq-producer.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?>

    <!-- 定义管理交换机、队列 -->
    <rabbit:admin connection-factory="connectionFactory"/>

    <!-- 定义持久化队列不存在则自动创建。不绑定到交换机则绑定到默认交换机。默认交换机类型为direct名字为“”路由键为队列的名称 -->
    <rabbit:queue id="spring_queue" name="spring_queue" auto-declare="true"/>

    <!-- 广播所有独立额都能收到消息 -->
    <!-- 定义广播交换机中的持久化队列不存在则自动创建 -->

            <rabbit:binding pattern="test.#" queue="spring_topic_queue_well2"/>

    </rabbit:topic-exchange>

    <!-- 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>

5编写测试代码发送消息

package com.juexing;

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 {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void testHelloWorld(){
        rabbitTemplate.convertAndSend("spring_queue", "hello world spring...");
    }

    @Test
    public void testFanout(){
        rabbitTemplate.convertAndSend("spring_fanout_exchange", "","spring_fanout...");
    }

    @Test
    public void testTopic(){
        rabbitTemplate.convertAndSend("spring_topic_exchange", "juexing.erci","spring_testTopic...");
    }

}

7运行测试代码查看效果

  • 两个交换机

在这里插入图片描述
spring_fanout_exchange交换机绑定了spring_fanout_queue1、spring_fanout_queue2 两个消息队列
在这里插入图片描述
spring_topic_exchange交换机绑定了spring_topic_queue_start、spring_topic_queue_swell、spring_topic_queue_well2

            <scope>test</scope>
        </dependency>
    </dependencies>

3创建 rabbitmq.properties 配置文件

rabbitmq.host=127.0.0.1
rabbitmq.port=5672
rabbitmq.username=guest
rabbitmq.password=guest
rabbitmq.virtual-host=/

4创建 spring-rabbitmq-consumer.xml 配置文件

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

                               username="${rabbitmq.username}"
                               password="${rabbitmq.password}"

<!--        <rabbit:listener ref="topicListenerWell2" queue-names="spring_topic_queue_well2"/>-->
    </rabbit:listener-container>

</beans>

5编写监听类消费消息

package com.juexing.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()));
    }
}

6编写测试类

package com.juexing;

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 testSpringQueue(){

    }
}

7运行测试类打印消息
