申请队列rabbit_reader在收到消息后处理数据帧时,如果channel id不是0(0代表连接),则认为是channel相关方法. handle_frame(Type, Channel, Payload, State = #v1{connection = #connection{protocol = Protocol}}) when ?IS_RUNNING(State) -> case rabbit_command_assembler:analyze_frame(Type, Payloa…

queue.declare即申请队列,首先对队列名作处理,若未指定队列名则随机生成一个,然后查询数据库队列是否已经创建,若创建完成则会申请队列返回 handle_method(#'queue.declare'{queue = QueueNameBin, passive = false, durable = DurableDeclare, exclusive = ExclusiveDeclare, auto_delete = AutoDelete, nowait = NoWait, argumen…

首先我们知道队列是先进先出的机制,所以在处理并发是个不错的选择.然后就写两个队列的简单应用. Queue 命名空间 命名空间:System.Collections,不在这里做过多的理论解释,这个东西非常的好理解. 可以看下官方文档:https://docs.microsoft.com/zh-cn/dotnet/api/system.collections.queue?view=netframework-4.7.2 示例代码 我这里就是为了方便记忆做了一个基本的例子,首先创建了QueueTest类…

1    queue与topic的技术特点对比 对比项 Topic Queue 概要 Publish Subscribe messaging 发布订阅消息 Point-to-Point 点对点 有无状态 topic数据默认不落地,是无状态的. Queue数据默认会在mq服务器上以文件形式保存,比如Active MQ一般保存在$AMQ_HOME\data\kr-store\data下面.也可以配置成DB存储. 完整性保障 并不保证publisher发布的每条数据,Subscriber都能接受到.…
