MVC3 / Structure Map 2.6.2 DI自定义控制器工厂问题(MVC3 / Structure Map 2.6.2 DI custom controller factory problem)

我将非参数类作为模型传递给控制器​​中的视图时出现问题。

我最近从Structure Map 2.5.3迁移到2.6.2。 一切都运行良好的2.5.3，它在2.6.2中不再起作用。 这是我的自定义控制器工厂：

public class StructureMapControllerFactory : DefaultControllerFactory { protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { try { return ObjectFactory.GetInstance(controllerType) as Controller; } catch (StructureMapException) { Debug.WriteLine(ObjectFactory.WhatDoIHave()); throw; } } }

接线：

ControllerBuilder.Current.SetControllerFactory(typeof(StructureMapControllerFactory));

我的自定义模型绑定器抛出异常： http ： //screencast.com/t/xZDNAAmM

可能有什么问题？

I'm having problems with passing non-parameterless classes as models to a view in a controller.

I recently moved from Structure Map 2.5.3 to 2.6.2. Everything worked fine in 2.5.3 nad it doesn't work anymore in 2.6.2. Here is my Custom Controller factory:

public class StructureMapControllerFactory : DefaultControllerFactory { protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { try { return ObjectFactory.GetInstance(controllerType) as Controller; } catch (StructureMapException) { Debug.WriteLine(ObjectFactory.WhatDoIHave()); throw; } } }

And wiring it:

ControllerBuilder.Current.SetControllerFactory(typeof(StructureMapControllerFactory));

My Custom model binder throws an exception: http://screencast.com/t/xZDNAAmM

What could be a problem?

最满意答案

我不认为这与您的DI容器有任何关系。 当instance为null时，会对modelbinder进行调用，并且可能会尝试创建一个新的modelType实例，这是不可能的，因为它没有无参数构造函数。

我想你刚刚在你的modelType的构造函数中添加了一个构造函数参数

I don't think this has anything to do with your DI container. When instance is null the call to your modelbinder is made and probably it tries to create a new instance of modelType which is impossible as that doesn't have a parameterless constructor.

I think you just added a constructor parameter to the constructor of your modelType
