fanout 多播 在之前都是使用direct直连类型的交换机,通过routingkey来决定把消息推到哪个queue中. 而fanout则是把拿到消息推到与之绑定的所有queue中. 分析业务,怎样的场景需要它呢?某个用户注册了网站的用户,一般我们需要发送短信和邮件通知,莫非要在同一个consumer中把这两件事都做了?这不符合单一职责,可是发送的消息是一样的,只是方式不一样.要使用两种routingkey都发送一次?这显然也不是我们想要的.所以fanout出现了 fanout类型的excha…

前面第六章我们使用的是direct直连模式来进行消息投递和分发.本章将介绍如何使用fanout模式将消息推送到多个队列. 有时我们会遇到这样的情况,多个功能模块都希望得到完整的消息数据.例如一个log的消息,一个我们希望输出在屏幕上实时监控,另外一个用户持久化日志.这时就可以使用fanout模式.fanout模式模式不像direct模式通过routingkey来进行匹配,而是会把消息发送到所以的已经绑定的队列中. 新建FanoutProduct用来发布消息.FanoutCustomerA和Fan…

一. 消息的广播需要exchange:exchange是一个转发器,其实把消息发给RabbitMQ里的exchange fanout: 所有bind到此exchange的queue都可以接收消息,广播 direct: 通过routingKey和exchange决定的那个唯一的queue可以接收消息 topic:所有符合routingKey(此时可以是一个表达式)的routingKey所bind的queue可以接收消息 headers:通过headers来决定把消息发给哪些queue,用的比较少…

就目前来说,Exchange是与消息发送端有关的,因为它可以指定将消息发送到哪个或哪些队列中. 本篇文章介绍的fanout类型就是指定将消息群发到与Exchange绑定的所有队列中. fanout这个单词,我看好多都翻译为扇出.扇出是个什么鬼?不知火舞拿个扇子出去秀身材?....还是回归正题! 反正知道fanout是在RabbitMQ中是群发的意思就OK了. 说到群发,肯定首先是要有一群队列Queue,其次还要有一个Exchange才行!那么,来吧,翠花,上代码!!!我们在代码中详见! //首先…
