SpringBoot整合RabbitMQ

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 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId></dependency><dependency><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"?>

</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 {@Autowiredprivate RabbitTemplate rabbitTemplate;@Testpublic void testHelloWorld(){rabbitTemplate.convertAndSend("spring_queue", "hello world spring...");}@Testpublic void testFanout(){rabbitTemplate.convertAndSend("spring_fanout_exchange", "","spring_fanout...");}@Testpublic void testTopic(){rabbitTemplate.convertAndSend("spring_topic_exchange", "juexing.erci","spring_testTopic...");}}

（6）项目结构图展示

（7）运行测试代码，查看效果

• 两个交换机

spring_fanout_exchange交换机，绑定了spring_fanout_queue1、spring_fanout_queue2 两个消息队列

spring_topic_exchange交换机，绑定了spring_topic_queue_start、spring_topic_queue_swell、spring_topic_queue_well2

• 6个消息队列，与未消费的消息。
  

SpringBoot整合RabbitMQ，消费者

rabbitmq.host=127.0.0.1
rabbitmq.port=5672
rabbitmq.username=guest

rabbitmq.virtual-host=/

（4）创建 spring-rabbitmq-consumer.xml 配置文件

（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 {@Overridepublic 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 {@Testpublic void testSpringQueue(){}
}

（7）运行测试类，打印消息
