如何将 MediatR 与我的业务层分离 [英] How to decouple MediatR from my business layer

问题描述

早上好.

我在我的项目中使用域事件，我发现实现它的最简单方法是使用 MediatR.但是我不希望我的项目直接依赖它，我想应用依赖倒置来隐藏库.

I'm using domain events in my project, and the easiest way i found to implement it was by using MediatR. But i don't want my project to directly depend on it, i want apply dependency inversion to hide the library.

由于 INotification 接口，在 Mediator 中具有依赖关系的当前代码

Current code that has a dependency in Mediator, because of INotification interface

public class EmailConfirmedEvent : INotification
{
    public Guid PassengerId { get; }
    public string Email { get; }

    public EmailConfirmedEvent(Guid passengerId, string email)
    {
        Email = email;
        PassengerId = passengerId;
    }
}

但我想成为这样:

public class EmailConfirmedEvent : IMyProjectDomainEvent
{
    public Guid PassengerId { get; }
    public string Email { get; }

    public EmailConfirmedEvent(Guid passengerId, string email)
    {
        Email = email;
        PassengerId = passengerId;
    }
}

通过某种方式，我需要从中介事件/事件处理程序转换"到我的项目事件/事件处理程序.

By some way i'll need to "convert" from mediator events/event handlers to my project events/event handlers.

这样做的最佳方法是什么.提前致谢.

What's the best way to do this. Thanks in advance.

推荐答案

我最终使用 StructureMap 和反射创建了域事件自定义代码，以在运行时解析事件处理程序.此处的代码示例:https://github.com/Henry-Keys/domain-events-样品

I ended up creating my domain event custom code using StructureMap and reflection to resolve the event handlers at runtime. Code sample here: https://github.com/Henry-Keys/domain-events-sample
