发送消息到任意虚拟主机/与 RabbitMQ/Spring AMQP 交换

我使用 RabbitMQ 和 Spring AMQP 发送消息.

I use RabbitMQ and Spring AMQP to send messages.

我有这个片段:

rabbitTemplate.convertAndSend(exchange, key, object);

这在我操作单个 VHOST 时有效.

This works when I operate on a single VHOST.

我必须从 1 个队列接收消息并将它们重新发送到 N 个交换机(在许多不同的 VHOST 上).我如何在 Spring AMQP (ver 1.2) 中做到这一点?

I have to receive messages from 1 queue and resend them to N exchanges (on many different VHOSTs). How can I do it in Spring AMQP (ver 1.2)?

有什么比在我的 xml 上下文中手动定义 (对于每个 VHOST)和相关元素更好的了?

Is there anything better than manually defined <rabbit:connection-factory> (for each VHOST) and related elements in my xml context?
