您好我正在阅读“Apress Pro ASP.NET MVC 5”这本书我已经下载了第7章,这是一个使用ninject运行的应用程序。 第一期是
1st issue snagit 我读到这是一个Ninject问题,解决了将此代码添加到SportsStoreWebUI web.config:
enter code here
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
现在,当我尝试运行App时,我得到了这个问题。
Error activating IProductRepository
No matching bindings are available, and the type is not self-bindable.
激活路径:
1)将依赖项IProductRepository
注入到ProductController
类型的构造函数的参数productRepository中
2)请求ProductController
建议:
1)确保您已为IProductRepository
定义了绑定。
2)如果在模块中定义了绑定,请确保已将模块加载到内核中。
3)确保您没有意外创建多个内核。
4)如果使用构造函数参数,请确保参数名称与构造函数参数名称匹配。
5)如果使用自动模块加载,请确保搜索路径和过滤器正确无误。
NinjectWebCommon.cs 的内容是
[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(SportsStore.WebUI.App_Start.NinjectWebCommon), "Start")]
[assembly: WebActivatorEx.ApplicationShutdownMethodAttribute(typeof(SportsStore.WebUI.App_Start.NinjectWebCommon), "Stop")]
namespace SportsStore.WebUI.App_Start
{
using System;
using System.Web;
using Microsoft.Web.Infrastructure.DynamicModuleHelper;
using Ninject;
using Ninject.Web.Common;
public static class NinjectWebCommon
{
private static readonly Bootstrapper bootstrapper = new Bootstrapper();
/// <summary>
/// Starts the application
/// </summary>
public static void Start()
{
DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
bootstrapper.Initialize(CreateKernel);
}
/// <summary>
/// Stops the application.
/// </summary>
public static void Stop()
{
bootstrapper.ShutDown();
}
/// <summary>
/// Creates the kernel that will manage your application.
/// </summary>
/// <returns>The created kernel.</returns>
private static IKernel CreateKernel()
{
var kernel = new StandardKernel();
try
{
kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
RegisterServices(kernel);
return kernel;
}
catch
{
kernel.Dispose();
throw;
}
}
/// <summary>
/// Load your modules or register your services here!
/// </summary>
/// <param name="kernel">The kernel.</param>
private static void RegisterServices(IKernel kernel)
{
}
}
}
我已经找了但是我没有发现错误。
非常感谢。
答案 0 :(得分:2)
您没有在NinjectWebCommon中添加RegisterServices:
System.Web.Mvc.DependencyResolver.SetResolver(new NinjectDependencyResolver(kernel));
答案 1 :(得分:0)
清单7-2:在NinjectWebCommon.cs文件中集成Ninject(第166页)
private static void RegisterServices(IKernel kernel) {
System.Web.Mvc.DependencyResolver.SetResolver(new SportsStore.WebUI.Infrastructure.NinjectDependencyResolver(kernel));
}
