先引入依赖：

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

使用的Spring Boot的版本是：2.0.4.RELEASE


由于Spring Boot跑单元测试的时候，也需要一个Spring Boot Application，因此我们手动构造一个，并且加入@EnableRabbit注解，
启动监听器。

import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.core.env.StandardEnvironment; import org.springframework.amqp.rabbit.annotation.EnableRabbit;   /**  * 由于是基于spring boot test组件进行单元测试,需要构建一个TestApplication上下文  */ @SpringBootApplication @EnableRabbit public class TestApplication {       public static void main(String[] args){         SpringApplicationBuilder builder = new SpringApplicationBuilder();         builder.environment(new StandardEnvironment());         builder.sources(TestApplication.class);         builder.main(TestApplication.class);         builder.run(args);     } }

直接编写发送消息的测试类：

import org.junit.Test; import org.springframework.amqp.core.*; import org.springframework.amqp.rabbit.core.RabbitAdmin; import org.springframework.amqp.rabbit.core.RabbitTemplate; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.junit.runner.RunWith; import org.springframework.test.context.junit4.SpringRunner;   @RunWith(SpringRunner.class) @SpringBootTest(classes = TestApplication.class) public class SpringBootMqSendTest{     private final static String EXCHANGE_NAME = "hello_fanout_1";     private final static String QUEUE_NAME = "hello_queue_1";       @Autowired     private RabbitAdmin rabbitAdmin;       @Autowired     private RabbitTemplate rabbitTemplate;       @Test     public void testSend(){         FanoutExchange fanoutExchange = new FanoutExchange(EXCHANGE_NAME, false, false);         Queue queue = new Queue(QUEUE_NAME, false);         rabbitAdmin.declareExchange(fanoutExchange);         rabbitAdmin.declareQueue(queue);         rabbitAdmin.declareBinding(BindingBuilder.bind(queue).to(fanoutExchange));           Message message = new Message("hello world.".getBytes(), new MessageProperties());         rabbitTemplate.send(EXCHANGE_NAME, "", message);     } }

编写消息消费者：

import org.springframework.amqp.core.Message; import org.springframework.amqp.rabbit.annotation.RabbitListener; import org.springframework.stereotype.Component;   @Component public class SpringBootMsqConsumer {     @RabbitListener(queues = "hello_queue_1")     public void receive(Message message) {         System.out.println("receive message:" + new String(message.getBody()));     } }

编写消息测试类：

import org.junit.Test; import org.springframework.amqp.core.*; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.junit.runner.RunWith; import org.springframework.test.context.junit4.SpringRunner;   @RunWith(SpringRunner.class) @SpringBootTest(classes = TestApplication.class) public class SpringBootMqConsumerTest {     @Autowired     private SpringBootMsqConsumer springBootMsqConsumer;       @Test     public void testConsumer(){     } }

执行testConsumer方法后，控制台输出：receive message:hello world.
