Question

我安装了Unity，并按照这个家伙的示例将依赖项注入到我的mvc应用程序中，Link现在，当我运行我的项目时，我面临以下豁免。

System.InvalidOperationException：'尝试创建一个控制器时发生错误键入“ SaaS.Controllers.AccountController”。确保控制器具有无参数公共构造函数

InvalidRegistrationException：类型的异常抛出了“ Unity.Exceptions.InvalidRegistrationException”。

 [Authorize]
public class AccountController : Controller
{
    private ApplicationSignInManager _signInManager;
    private ApplicationUserManager _userManager;
    private ITenantRepository TenantRepo;
    private ISetupRepository SetupRepo;
    private IAppUserRepository AppUserRepo;
    private IEmployeeRepository EmployeeRepo;

    public AccountController()
    {

    }

    public AccountController(ApplicationUserManager userManager, ApplicationSignInManager signInManager, ITenantRepository TenantRepo,
        ISetupRepository SetupRepo, IAppUserRepository AppUserRepo, IEmployeeRepository EmployeeRepo)
    {
        UserManager = userManager;
        SignInManager = signInManager;
        this.TenantRepo = TenantRepo;
        this.SetupRepo = SetupRepo;
        this.AppUserRepo = AppUserRepo;
        this.EmployeeRepo = EmployeeRepo;
    }

一个仓库

    public static void RegisterComponents()
        {
        var container = new UnityContainer();

        container.RegisterType<ISetupRepository, SetupRepository>();
        container.RegisterType<ITenantRepository, TenantRepository>();
        container.RegisterType<ISetupLocationRepository, SetupLocationRepository>();
        container.RegisterType<ISetupCalendarOfficeRepository, SetupCalendarOfficeRepository>();
        container.RegisterType<IAppUserRepository, AppUserRepository>();
        container.RegisterType<ICacheService, InMemoryCache>();

        container.RegisterType<IEmpPersonalDetailRepository, EmpPersonalDetailRepository>();
        container.RegisterType<IEmpSportRepository, EmpSportRepository>();
        container.RegisterType<IEmployeeRepository, EmployeeRepository>();

        container.RegisterType<IEmpContactDetailRepository, EmpContactDetailRepository>();

        container.RegisterType<IEmpEmploymentDetailRepository, EmpEmploymentDetailRepository>();
        container.RegisterType<IEmpVacationEntitlementRepository, EmpVacationEntitlementRepository>();
        container.RegisterType<IEmpCalendarRepository, EmpCalendarRepository>();

        container.RegisterType<IEmpSalaryRepository, EmpSalaryRepository>();
        container.RegisterType<ISetupSalaryComponantRepository, SetupSalaryComponantRepository>();
        container.RegisterType<ISetupPayGradeRepository, SetupPayGradeRepository>();
        container.RegisterType<IEmpPartSalaryRepository, EmpPartSalaryRepository>();
        container.RegisterType(typeof(IUserStore<ApplicationUser>), typeof(UserStore<ApplicationUser>));


        DependencyResolver.SetResolver(new UnityDependencyResolver(container));
    }

    public class SetupRepository : ISetupRepository/*, IDisposable*/
    {
    [Dependency]
    public DataBaseContext context { get; set; }

    public void Add(Setup entity)
    {
            context.Setups.Add(entity);
            context.SaveChanges();
    }
    }

问题是AccountController构造函数具有用于ApplicationUserManager和ApplicationSignInManager的参数，并且这些参数未在您的容器中注册，因此Unity不在从那里获取这些值的位置。如果您注册这两种类型（或实例），那么它应该对您有用。

挣扎与豁免“ Unity.Exceptions.InvalidRegistrationException”
