RabbitMq主题交换(RabbitMq topic exchange)
是否可以使用RabbitMQ主题交换实现以下场景。
可以说我有两个队列:
队列1:路由键MainRoute.Route1
队列2:路由密钥MainRoute.Route2
当我使用路由键发布我的消息时:
MainRoute.Route1 - > Queue1
MainRoute.Route2 - > Queue2
MainRoute - > Queue1和Queue2
是否可以在不实施某些特殊过滤,路由过程的情况下实现这一目标?
如果没有,请您就该问题的可能解决方案提出建议。
谢谢。
Is it possible to achieve the following scenario using RabbitMQ topic exchange.
Lets say I have two queues:
Queue1: routing key MainRoute.Route1
Queue2: routing key MainRoute.Route2
When I publish my message with routing key:
MainRoute.Route1 -> Queue1
MainRoute.Route2 -> Queue2
MainRoute -> Queue1 and Queue2
Is it possible to achieve this without implementing some special filtering, routing process ?
If not can you please advise on a possible solution for the problem.
Thank you.

看起来如果您不相信隐藏/不可编辑的设置字段不够,则需要通过beforeSave回调函数实现检查。
在callBack中,您可以检查关系是否已经存在,然后再用错误编辑的值覆盖它们。
