c#-4.0 - 如何为 asp.net MVC 5 配置 StructureMap

Question

我正在低于错误。我设置它类似于 asp.net mvc 4。

No parameterless constructor defined for this object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

异常详细信息:System.MissingMethodException:没有为此对象定义无参数构造函数。

终于发现实际异常“尝试获取HomeController类型的实例时发生激活错误，键“””

当我要将服务类注入(inject)家庭 Controller 时发生错误

以下步骤对我有用:

在 Visual Studio 2013 RTM

中创建一个新的 ASP.NET MVC 5 应用程序

安装 StructureMap.MVC4 NuGet:

Install-Package StructureMap.MVC4

创建一个新界面:

public interface IDependency
{
    string SayHello();
}

实现这个接口(interface):

public class ConcreteDepenedency: IDependency
{
    public string SayHello()
    {
        return "Hello World";
    }
}

让 HomeController 使用这个接口(interface):

public class HomeController : Controller
{
    private readonly IDependency dependency;
    public HomeController(IDependency dependency)
    {
        this.dependency = dependency;
    }

    public ActionResult Index()
    {
        return Content(this.dependency.SayHello());
    }
}

在 ~/DependencyResolution/Ioc.cs 中配置您的容器:

using StructureMap;
using WebApplication1.Controllers;

namespace WebApplication1.DependencyResolution {

    public static class IoC {

        public static IContainer Initialize() {

            ObjectFactory.Initialize(x =>
            {
                x.For<IDependency>().Use<ConcreteDepenedency>();
            });

            return ObjectFactory.Container;
        }
    }
}

使用 Ctrl+F5

运行您的应用程序

ConcreteDependency成功注入(inject)HomeController .
