92棋牌游戏下载我们最常使用的就是type属性,下面就详细解释type属性

Fanout Exchange

全网RabbitMQ总结,别再说你不会RabbitMQ
发送到该交换机的消息都会路由到与该交换机绑定的所有队列上,可以用来做广播

Direct Exchage

全网RabbitMQ总结,别再说你不会RabbitMQ
92棋牌游戏下载把消息路由到BindingKey和RoutingKey完全匹配的队列中

Topic Exchange

全网RabbitMQ总结,别再说你不会RabbitMQ
前面说到,direct类型的交换器路由规则是完全匹配RoutingKey和BindingKey。topic和direct类似,也是将消息发送到RoutingKey和BindingKey相匹配的队列中,只不过可以模糊匹配。

全网RabbitMQ总结,别再说你不会RabbitMQ
假如现在有2个RoutingKey为java.lang和java.util.concurrent的消息,java.lang会被路由到Consumer1和Consumer2,java.util.concurrent会被路由到Consumer2。

92棋牌游戏下载1、ZIDONGQUEREN(autoAck=true)

92棋牌游戏下载2、SHOUDONGQUEREN(autoAck=false)

消费者在消费消息的时候,可以指定autoAck参数

确认消息只有一种方法

basicAck(long deliveryTag, boolean multiple)

而拒绝消息有两种方式

我们最常用的就是失败通知和发布者确认

当消息不能被路由到某个queue时,我们如何获取到不能正确路由的消息呢?
