asp.net 2.0标识不统一解决默认的用户存储 [英] asp.net identity 2.0 unity not resolving default user store

问题描述

尝试配置使用Unity.Mvc5与使用Identity 2.0和样板标识2.0样品的MVC 5应用程序统一时，我得到下面的异常。我已阅读本SO 配置统一DI为ASP.NET身份并我还没有对我缺少什么，我不清楚。我究竟做错了什么？

当前类型，System.Data.Common.DbConnection，是一个抽象类，不能构成。是否缺少类型映射？

[ResolutionFailedException：依赖关系解析失败，TYPE =myApp.Web.Controllers.AccountControllerNAME =（无）。
在解析

：当发生异常。

异常是：出现InvalidOperationException - 当前类型，System.Data.Common.DbConnection，是一个抽象类，不能构成。是否缺少类型映射？

目前的异常时，该容器是：

解决myApp.Web.Controllers.AccountController，（无）
解决构造myApp.Web.Controllers.AccountController的参数的UserManager（myApp.Web.Models.ApplicationUserManager的UserManager）
解决myApp.Web.Models.ApplicationUserManager，（无）
解决构造函数参数专卖店 myApp.Web.Models.ApplicationUserManager(Microsoft.AspNet.Identity.IUserStore<$c$c>1[[myApp.Web.DAL.Profiles.ApplicationUser, myApp.Web，版本= 1.0.0.0，文化=中立，公钥=空]店）
解决Microsoft.AspNet.Identity.EntityFramework.UserStore1[myApp.Web.DAL.Profiles.ApplicationUser],(none) （从Microsoft.AspNet.Identity.IUserStore映射 1 [myApp.Web.DAL.Profiles.ApplicationUser]，（无））
解决构造Microsoft.AspNet.Identity.EntityFramework.UserStore 参数背景1 [myApp.Web.DAL.Profiles.ApplicationUser，myApp.Web，版本= 1.0.0.0，文化=中立，公钥=空]（System.Data.Entity.DbContext上下文）
解决System.Data.Entity.DbContext，（无）
解决参数existingConnection构造System.Data.Entity.DbContext的（System.Data.Common.DbConnection existingConnection，System.Data.Entity.Infrastructure.DbCompiledModel模型，System.Boolean contextOwnsConnection）
解决System.Data.Common.DbConnection，（无）

帐户控制器我已经修改了它

 公开的AccountController（ApplicationUserManager的UserManager）
 {
      _userManager =的UserManager;
 } 私人ApplicationUserManager _userManager;
 

容器我已经注册

  container.RegisterType＆LT; ApplicationUserManager＆GT;（新HierarchicalLifetimeManager（））;
container.RegisterType＆所述; IUserStore＆下; ApplicationUser＆gt;中UserStore＆所述; ApplicationUser＆GT;＆GT;（新HierarchicalLifetimeManager（））;
 

解决方案

我看到你找到了解决办法，但我想我有一个简单的办法。

您正在使用实体框架，对不对？所以，你的应用程序几乎可以肯定有东西从的DbContext 继承（大概是从 IdentityContext＆LT继承; TUSER＆GT; ，这反过来从继承在这种情况下，的DbContext ）。在默认的模板是ApplicationDbContext。

在你的作文根，你可以再补充 container.RegisterType＆LT;的DbContext，ApplicationDbContext＆GT;（新HierarchicalLifetimeManager（））; （显然编辑这个，如果你不叫ApplicationDbContext ）。

i get the following exception when trying to configure Unity using Unity.Mvc5 with an MVC 5 application using Identity 2.0 and the Identity 2.0 Samples boilerplate. i have read this SO Configure Unity DI for ASP.NET Identity and i'm still not clear on what i'm missing. What am i doing wrong here?

The current type, System.Data.Common.DbConnection, is an abstract class and cannot be constructed. Are you missing a type mapping?

[ResolutionFailedException: Resolution of the dependency failed, type = "myApp.Web.Controllers.AccountController", name = "(none)". Exception occurred while: while resolving.

Exception is: InvalidOperationException - The current type, System.Data.Common.DbConnection, is an abstract class and cannot be constructed. Are you missing a type mapping?

At the time of the exception, the container was:

Resolving myApp.Web.Controllers.AccountController,(none) Resolving parameter "userManager" of constructor myApp.Web.Controllers.AccountController(myApp.Web.Models.ApplicationUserManager userManager) Resolving myApp.Web.Models.ApplicationUserManager,(none) Resolving parameter "store" of constructor myApp.Web.Models.ApplicationUserManager(Microsoft.AspNet.Identity.IUserStore1[[myApp.Web.DAL.Profiles.ApplicationUser, myApp.Web, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] store) Resolving Microsoft.AspNet.Identity.EntityFramework.UserStore1[myApp.Web.DAL.Profiles.ApplicationUser],(none) (mapped from Microsoft.AspNet.Identity.IUserStore1[myApp.Web.DAL.Profiles.ApplicationUser], (none)) Resolving parameter "context" of constructor Microsoft.AspNet.Identity.EntityFramework.UserStore1[[myApp.Web.DAL.Profiles.ApplicationUser, myApp.Web, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]](System.Data.Entity.DbContext context) Resolving System.Data.Entity.DbContext,(none) Resolving parameter "existingConnection" of constructor System.Data.Entity.DbContext(System.Data.Common.DbConnection existingConnection, System.Data.Entity.Infrastructure.DbCompiledModel model, System.Boolean contextOwnsConnection) Resolving System.Data.Common.DbConnection,(none)

account controller as i have modified it

 public AccountController(ApplicationUserManager userManager)
 {
      _userManager = userManager;
 }

 private ApplicationUserManager _userManager;

containers i have registered

container.RegisterType<ApplicationUserManager>(new HierarchicalLifetimeManager());
container.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>(new HierarchicalLifetimeManager());

解决方案

I see you found a solution, but I think I have a simpler one.

You're using Entity Framework, right? So your application almost certainly has something inheriting from DbContext (probably inheriting from IdentityContext<TUser>, which in turn inherits from DbContext in this case). In the default template it's ApplicationDbContext.

In your composition root you can just add container.RegisterType<DbContext, ApplicationDbContext>(new HierarchicalLifetimeManager()); (obviously edit this if yours isn't called ApplicationDbContext).
