C# NHibernate无法确定X的类型

我已经为我的MVC 3 ASP.NET项目使用NHibernate创建了一个自定义成员资格提供程序

我对用户类有一些问题。我得到以下错误：

无法确定以下项的类型： FluentNHibernateMembershipProvider.Models.User， FluentNHibernateMembershipProvider，版本=1.0.0.0，区域性=中性， PublicKeyToken=null，用于以下列：NHibernate.Mapping.Column（用户）

当我调用以下命令时发生错误：

_sessionFactory = cfg.BuildSessionFactory();

User.cs文件如下所示：

namespace FluentNHibernateMembershipProvider.Models
{
    public class User
    {
        public virtual int UserId { get; protected set; }
        public virtual string Username { get; set; }
        public virtual DateTime CreateDate { get; set; }
        public virtual string ConfirmationToken { get; set; }
        public virtual bool IsConfirmed { get; set; }
        public virtual DateTime LastPasswordFailureDate { get; set; }
        public virtual int PasswordFailuresSinceLastSuccess { get; set; }
        public virtual string Password { get; set; }
        public virtual DateTime PasswordChangeDate { get; set; }
        public virtual string PasswordSalt { get; set; }
        public virtual string PasswordVerificationToken { get; set; }
        public virtual DateTime PasswordVerificationTokenExpirationDate { get; set; }
        public virtual IList<Role> Roles { get; set; }

        public User()
        {
            Roles = new List<Role>();
        }

    }
}

我认为您的问题来自以下映射：

public OAuthTokenMappings()
    {
        CompositeId()
            .KeyReference(c => c.Provider, "Provider")
            .KeyReference(c => c.ProviderUserId, "ProviderUserId");
        Map(c => c.Token);
        Map(c => c.User); //This is most likely the culprit. Should be a References or HasOne mapping
        Map(c => c.Secret);
    }

问题可能在另一个引用用户类的映射中。你有这样的地图吗？您可以尝试消除其他映射，然后一次添加一个，以查看哪个映射存在问题。我已经用另外两个类和相应的映射更新了这个问题。
