SpringBoot：rabbitmq使用，@EnableRabbit + @RabbitListener 作用， AmqpAdmin：创建和删除 Queue，Exchange，Binding

下载安装：

在自己的虚拟机上面用命令下载

 docker pull registry.docker-cn.com/library/rabbitmq:3.6-management           management表示是带管理页面的

启动：

docker run -d -p 5672:5672  -p 15672:15672 --name myrabbitmq  3951818b0610

然后配置一个转化器（转成json），rabbitmqTemplate操作发送和接收消息

@Configuration
public class myConfig {

    @Bean
    public MessageConverter messageConverter() {
        return new Jackson2JsonMessageConverter();

    }
}

配置文件

spring:
  rabbitmq:
    host: 192.168.1.113
    username: guest
    password: guest
    virtual-host: /
    port: 5672

测试：rabbitmqTemplate操作发送和接收消息

 /**
     * 单播
     */
    @Test
    public void test1() {
//       Message需要自己构建一个自定义的消息内容和消息体
//        rabbitTemplate.send(exchange,routingKey,message);
        Map map = new HashMap<>();
        map.put("msg","这是一个消息");
        map.put("", Arrays.asList("newsjj",true,1));
        //对象被序列号后发送出去
        rabbitTemplate.convertAndSend("exchange.direct","atguigu.news",map);

    }

    @Test
    public void receive() {
//        Message atguigu = rabbitTemplate.receive("atguigu");
        Object atguigui = rabbitTemplate.receiveAndConvert("atguigui");
        System.out.print(atguigui.getClass());
        System.out.println(atguigui);
    }

    /**
     * 广播
     */
    @Test
    public void sendMsg(){
        rabbitTemplate.convertAndSend("exchange.fanout","",new Book("红楼梦","曹雪芹"));
    }

@EnableRabbit +  @RabbitListener 监听消息队列的内容

@EnableRabbit 在主main方法开启基于注解的rabbit

 @RabbitListener(queues = "atguigu.news")
    public void receive(Book book){
        System.out.println("收到消息："+book);
    }

    @RabbitListener(queues = "atguigu")
    public void receive02(Message message){
        System.out.println(message.getBody());
        System.out.println(message.getMessageProperties());
    }

 AmqpAdmin ： RabbitMQ系统管理功能组件; 
 AmqpAdmin：创建和删除 Queue，Exchange，Binding

@Test
	public void createExchange(){
        //创建exchange
		amqpAdmin.declareExchange(new DirectExchange("amqpadmin.exchange"));
		System.out.println("创建完成");

	}

@Test
	public void createExchange(){

    //创建queue
		amqpAdmin.declareQueue(new Queue("amqpadmin.queue",true));

	}

@Test
	public void createExchange(){
       
//       创建banding
		amqpAdmin.declareBinding(new Binding("amqpadmin.queue", 
         Binding.DestinationType.QUEUE,"amqpadmin.exchange","amqp.haha",null));

		
	}
