Rabbitmq 根据用户数量动态创建队列

如何解决Rabbitmq 根据用户数量动态创建队列

我有一个场景，我必须将我收到的消息列表路由到各个用户。假设如果我有

org.springframework.context.support.AbstractApplicationContext     refresh

producer.js

messages = [
  { text: 'hi',user_id: 1 },{ text: 'hi',user_id: 2 },user_id: 3 },user_id: 4 },user_id: 5 },];

consumer.js

var amqp = require('amqplib/callback_api');

amqp.connect('amqps://dgszsgqj:C_wg8fkFrcl6ukZjxBjCcpgc_Pa2j-r9@snake.rmq2.cloudamqp.com/dgszsgqj',function(error0,connection) {

    var exchange = 'messages';
  
    channel.assertExchange(exchange,'direct',{
      durable: false

我在博客中读到动态创建队列是一种反模式。 https://derickbailey.com/2015/09/02/rabbitmq-best-practices-for-designing-exchanges-queues-and-bindings/

我也尝试在生产者端创建队列，这是创建队列，但无法使用来自该队列的消息，因为我在使用它时不知道队列的名称。

我该如何有效地处理这种情况？
