本文介绍了如何在SpringBoot应用中整合RabbitMQ，使用RabbitTemplate进行消息发送和接收，以及AmqpAdmin组件来管理队列、交换器和绑定。通过@RabbitListener和@EnableRabbit注解实现消息监听，详细讲解了测试用例和配置过程。

5.1.1、基本测试

1.引 spring-boot-starter-amqp**

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.amqp</groupId>
            <artifactId>spring-rabbit-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

自动配置原理说明 RabbitAutoConfiguration

1、有自动配置了连接工厂CachingConnectionFactory；获取与rabbitmq连接信息

@Configuration
@ConditionalOnClass({
   
    RabbitTemplate.class, Channel.class })
@EnableConfigurationProperties(RabbitProperties.class)
@Import(RabbitAnnotationDrivenConfiguration.class)
public class RabbitAutoConfiguration {
   
   

	@Configuration
	@ConditionalOnMissingBean(ConnectionFactory.class)
	protected static class RabbitConnectionFactoryCreator {
   
   

		@Bean
		public CachingConnectionFactory rabbitConnectionFactory(RabbitProperties properties,
				ObjectProvider<ConnectionNameStrategy> connectionNameStrategy) throws Exception {
   
   
            
           ... 
        }
        ...

2、RabbitProperties封装了 RabbitMQ的配置

@ConfigurationProperties(prefix = "spring.rabbitmq")
public class RabbitProperties {
   
   

	/**
	 * RabbitMQ host.
	 */
	private String host = "localhost";

	/**
	 * RabbitMQ port.
	 */
	private int port = 5672;
    ..
