错误消息发布到默认EasyNetQ_Default_Error_Queue时,我有四个使用者,是否有可能每个队列使用者都编写自己的错误交换

例如;

Queue Name : A    ErrorExchange :A_ErrorExchange
Queue Name : B    ErrorExchange :B_ErrorExchange
bus.Advanced.Conventions.ErrorExchangeNamingConvention = new ErrorExchangeNameConvention(info => "A_DeadLetter");

bus.Advanced.Conventions.ErrorExchangeNamingConvention = new ErrorExchangeNameConvention(info2 => "B_DeadLetter");

最佳答案

从您提供的代码来看,您已经差不多了-您只需要适本地覆盖ErrorExchangeNamingConventionErrorQueueNamingConvention

例如,这是一个方法,该方法将返回IBus的实例,并覆盖这些约定以合并指定的使用者名称:

public IBus CreateBus(string connectionString, string consumerName)
{
    var bus = RabbitHutch.CreateBus(connectionString);

    // Modify the following to create your error exchange name appropriately
    bus.Advanced.Container.Resolve<IConventions>().ErrorExchangeNamingConvention =
        info => consumerName + "_ErrorExchange";

    // Modify the following to create your error queue name appropriately
    bus.Advanced.Container.Resolve<IConventions>().ErrorQueueNamingConvention =
        () => consumerName + "_ErrorQueue";

    return bus;
}
