spring整合rabbitmq

spring整合rabbitmq的步骤：
在maven的pom文件中添加如下：

<dependency>
<groupId>com.rabbitmq</groupId>
<artifactId>amqp-client</artifactId>
<version>3.6.5</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
<version>2.1.3</version>
</dependency>

在bean工厂中添加连接工厂和rabbitAdmin实例

@Bean
public ConnectionFactory connectionFactory(){
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        connectionFactory.setAddresses("192.168.1.177:5672");
        connectionFactory.setUserName("guest");
        connectionFactory.setUserName("guest");
        connectionFactory.setVirtualHost("/");
        return connectionFactory;
}

@Bean
public RabbitAdmin rabbitAdmin(ConnectionFactory connectionFactory){
        RabbitAdmin rabbitAdmin = new RabbitAdmini(connectionFactory);
        rabbitAdmin.setAutoStartup(true);
        return rabbitAdmin;
}

利用rabbitAdmin声明：

rabbitAdmin.declareBinding(BindingBuilder.bind(new Queue("topic.queue"),false).to(new TopicExchange("topic".false,false)).with("test.#"));

bind：创建队列
to ：绑定交换机
with ：路由key

底层是通过rabbitTemplate调用execute方法
