在MVC5中使用Ninject 依赖注入

 

各大主流.Net的IOC框架性能测试比较 :

使用NuGet下载安装 Ninject，确认引用服务中存在 Ninject

在项目中新建 NinjectControllerFactory.cs 类

using BooksStore.Domain.Service.Book;
using BooksStore.Domain.Service.impl;
using Ninject;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace BooksStore.WebUI.Infrastructure
{
    public class NinjectControllerFactory:DefaultControllerFactory
    {
        private readonly IKernel _kernel;

        public NinjectControllerFactory()
        {
            _kernel = new StandardKernel();
            AddBindings();
        }

        protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
        {
            return controllerType == null
                ? null
                : (IController)_kernel.Get(controllerType);
        }

        /// <summary>
        /// 添加绑定
        /// </summary>
        private void AddBindings()
        {
            //绑定接口和实现类
            _kernel.Bind<IBookService>().To<BookService>();
        }
    }
}

在Global.asax 注册 这个容器

using BooksStore.WebUI.Infrastructure;
using System.Web.Mvc;
using System.Web.Routing;

namespace BooksStore.WebUI
{
    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            //注册Ninject容器
            ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory());

        }
    }
} 

在控制器中调用接口 使用Ninject依赖注入 就能正常调用接口

 [Ninject.Inject]
 public IBookService _IBookService { set; get; }

 使用构造函数注入

  private IBookService _bookService;
  public BookController(IBookService bookService)
  {
    _bookService = bookService;
  }
