Question

我已经从程序集中映射了所有类。当启动Rebus时应该提及：

Mapped MyNamespace.Events.EmailSend -> Rebus/Test/Input

但是当我尝试使用以下代码在处理程序中提交消息时出现错误：

await _bus.Send(new EmailSend
{
    MyProperty = 1
}).ConfigureAwait(false);

我也尝试使用.Reply()和.SendLocal()，但这并没有帮助我摆脱下面的错误。

堆栈跟踪：

Rebus.Retry.ErrorTracking.InMemErrorTracker WARN (Thread #10): Unhandled exception 1 while handling message with ID a2c3b234-f519-4d86-bec9-715b2045ef94: Rebus.Exceptions.RebusApplicationException: Message with ID a2c3b234-f519-4d86-bec9-715b2045ef94 and type MyNamespace.Events.EmailSend, MyAssembly.Messaging.Models could not be dispatched to any handlers

Answer 1

第一行确实说明了一切：

Rebus.Retry.ErrorTracking.InMemErrorTracker WARN (Thread #10): Unhandled exception 1 while handling message with ID a2c3b234-f519-4d86-bec9-715b2045ef94: Rebus.Exceptions.RebusApplicationException: Message with ID a2c3b234-f519-4d86-bec9-715b2045ef94 and type MyNamespace.Events.EmailSend, MyAssembly.Messaging.Models could not be dispatched to any handlers

注意最后一部分：

Message with ID a2c3b234-f519-4d86-bec9-715b2045ef94 and type MyNamespace.Events.EmailSend, MyAssembly.Messaging.Models could not be dispatched to any handlers

这意味着Rebus无法找到该消息的处理程序，即IHandleMessages<EmailSend>的实现。

如果您使用的是IoC容器，则此可以表示，虽然您可能已正确注册了处理程序类型，但其中一个依赖项无法解析。

如果你没有注册处理程序：我想这很明显：）

Answer 2

使用.ConfigureAwait（true）调用_bus.Send（），似乎需要＆＃34; false＆＃34;从公交车上提交信息时。

哦，处理程序类是内部的。

猜猜其中一个是真正的问题 - 或者是一个组合......

映射事件抛出
