Question

我在localhost上有两个不同的 RabbitMQ实例：5672和localhost：5676。我也在我的应用程序上下文中配置了它：

我的Spring Web应用程序向 rabbit（localhost：5672，id =“amqpTemplate”）生成消息，然后从队列中消耗并保存到DB。

保存到数据库应用程序后产生答案（确定或错误），我需要发布第二个 rabbitMQ（localhost：5676，id =“rabbitAnswer”）的答案。

当我尝试发布第二个兔子的答案（localhost：5676，id =“rabbitAnswer”）时，他们发布了第一只兔子，我不明白为什么???我在发送消息之前记录连接端口，它正确 - 5676，但是应用程序向5672发送消息。

我怀疑问题出在频道，因为在第二只兔子我没有看到任何打开的频道。那么，我如何向第二只兔子申报不同的频道并以正确的方式发送信息呢？

如何在一个Spring应用程序上下文中声明2个不同的rabbitMQ
