1.安装rabbitmq

2.创建springboot项目

3.配置连接

   spring:
   rabbitmq:
       host: 10.80.56.207
       port: 5672
       username: test
       password: test
       virtual-host: /test
       publisher-confirms: true

配置Config：Topic交换机、队列、绑定路由规则等

       @Configuration //配置类

       ExchangeBuilder.topicExchange(exchangeName).durable(true).build(); //声明交换机

       new Queue(queueName);//声明队列

       BindingBuilder.bind(queue).to(exchange).with("ceshi.#"); //通过路由规则绑定交换机和队列路由规则必须是以“.”隔开的字符

       @Configuration
   public class RabbitMqConfig {
               //交换机1

@Bean("exchange_test1")
public TopicExchange exchange1(){

return new TopicExchange("exchange_test1");
}

           //队列1
           @Bean("queue_test1")
           public Queue queue1(){
               return declare_Queue("queue_test1");
           }

           //绑定交换机1和队列1
           @Bean
           public Binding bind_Exchange_Queue(@Qualifier("exchange_test1") TopicExchange exchange,@Qualifier("queue_test1") Queue queue){

           // return BindingBuilder.bind(queue).to(exchange).with("test#").noargs();
               return BindingBuilder.bind(queue).to(exchange).with("ceshi.#");
           }
   }

生产者发送消息
   @Autowired
private AmqpTemplate amqpTemplate;

public void sendTest1(){
//交换机名称
//路由key名称
//具体消息内容
amqpTemplate.convertAndSend("exchange_test1","ceshi.ceshi","this is my message:fuck you");

}

消费者消费消息

@RabbitListener(queues={"queue_test1"}) //监听“queue_test1”队列
public void reciveTest1(String msg){

System.out.println("接收消息内容==="+msg);

}

生产者和消费者可以放到2个项目中，启动生产者发送消息，关闭消费者，然后在mq的管理页面查看消息状态

然后再启动消费者看消息状态
