Exchanges 目前有4 种类型为 Direct , Fanout , Topic , handers 。以下测试简单理解 Exchanges, Routing key 及 Queues 的关系。 首先创建3个 Exchanges 为 test_direct,test_fanout,test_topic,分别对应的类型为 direct,fanout,topic 。再创建7个队列为 queue00~queue06 。 绑定信息及测试结果: 绑定操作可在UI...
所以我们两个消费者都能收到消息,那如果我这个时候只想给其中一个发送,那么久必须要做路由key的区别,这样交换机才能针对的将消息推入到指定的队列中 这个就好比是我们去吃饭,有包间和大厅,服务员看到我点的菜,上面写着包间好,就将菜送到指定的包间,然后我消费她送来的菜品 上面理解的就不用看下面的截图了,已经...
会为每一个订阅者创建一个队列，而发布者发布消息时，会将消息放置在所有相关队列中 type=direct 队列...

We extend the Becke-Johnson approximation [J. Chem. Phys. 124, 221101 (2006)] of the exchange potential to two dimensions. We prove and demonstrate that a direct extension of the underlying formalism may lead to divergent behavior of the potential. We derive a cure to the approach by enforc...
