NServiceBus 3.0 DataBus 示例未找到消息类型的目标

Question

我正在尝试使用 NServiceBus 3 （又名 github master ），但在运行某些示例时遇到问题，即 DataBus 和 AzureDataBus 项目。

对于 DataBus 接收器，它似乎期望配置 MessageEndpointMapping，但根据我的理解，这配置了发送消息的位置，并且对于接收器/AsA_Server 来说不应该是必需的。添加此配置项似乎确实证实了这一点。

这是错误日志

如有任何帮助，我们将不胜感激。

好吧，今天再看一下这个，找到了一个有效的例子，并推断出这个例子能够正常工作。改变其实很简单。似乎 UnicastBus 尝试自动订阅，因此您需要为发送者提供类似以下内容......

internal class SetupDataBus : IWantCustomInitialization 
{ 
    public static string BasePath = "..\\..\\..\\storage"; 
    public void Init() 
    { 
        Configure.Instance.UnicastBus().DoNotAutoSubscribe().FileShareDataBus(BasePath); 
    }
}
