问题描述

Who has the responsibility to start and finish the Unit of work in a MVC architecture?

推荐答案

这不是一个控制器的责任，它违反了 SRP 。控制器甚至不应该知道的UOW的。在网上，每个请求对应一个UOW到服务器通常使用。在这种情况下，UOW应在一个请求结束被设置并启动某处的请求的开始后（理想启动UOW的应懒惰）。要做到这一点，最好的地方是使用Application_EndRequest和的Application_BeginRequest处理Global.asax中（或您的HttpApplication类）。结果
这可以通过IOC框架可以轻松实现（我最喜欢的是温莎），请参阅this问题了解实施细节。

It's not a responsibility of a controller, it violates SRP. Controller should not even know about UoW at all. In web, one UoW per request to server is usually used. In this case UoW should be disposed at the end of a request and started somewhere after the beginning of a request (ideally start of a UoW should be lazy). The best place to do this is Global.asax (or your HttpApplication class) using Application_EndRequest and Application_BeginRequest handlers.
This can be easily achieved with an IOC framework (my favorite is Windsor), see this question for implementation details.
