正如标题所说,我收到一条错误消息:“在创建SessionFactory时使用了无效或不完整的配置。检查PotentialReasons集合,以及InnerException以获取更多详细信息。”
我将从代码开始。
数据库:
用户表:
CREATE TABLE [dbo].[User] (
[Id] UNIQUEIDENTIFIER NOT NULL,
[Username] NVARCHAR (50) NULL,
[PasswordHash] CHAR (64) NOT NULL,
[Salt] CHAR (64) NOT NULL,
[Role] UNIQUEIDENTIFIER NOT NULL,
[Token] NVARCHAR (50) NOT NULL,
[TokenStamp] DATETIME NULL,
CONSTRAINT [PK_User] PRIMARY KEY CLUSTERED ([Id] ASC),
CONSTRAINT [FK_User_Role] FOREIGN KEY ([Role]) REFERENCES [dbo].[Role] ([Id])
);
角色表:
CREATE TABLE [dbo].[Role] (
[Id] UNIQUEIDENTIFIER NOT NULL,
[Name] NVARCHAR (50) NULL,
CONSTRAINT [PK_Role] PRIMARY KEY CLUSTERED ([Id] ASC)
);
用户类:
using System;
namespace Models
{
public class User : EntityBase
{
public virtual string Username { get; set; }
public virtual string PasswordHash { get; set; }
public virtual string Salt { get; set; }
public virtual Guid Role { get; set; }
public virtual string Token { get; set; }
public virtual DateTime TokenStamp { get; set; }
}
}
角色类:
namespace Models
{
public class Role : EntityBase
{
public virtual string Name { get; set; }
}
}
EntityBase:
using System;
namespace Models
{
public class EntityBase
{
public virtual Guid Id { get; set; }
}
}
用户地图:
using FluentNHibernate.Mapping;
using Models;
namespace NHibernate.Mapping
{
public class UserMap : ClassMap<User>
{
public UserMap()
{
Table("User");
Id(x => x.Id).GeneratedBy.GuidComb();
LazyLoad();
References(x => x.Role).Column("Role");
Map(x => x.Username).Column("Username");
Map(x => x.PasswordHash).Column("PasswordHash").Not.Nullable();
Map(x => x.Salt).Column("Salt").Not.Nullable();
Map(x => x.Token).Column("Token").Not.Nullable();
Map(x => x.TokenStamp).Column("TokenStamp");
}
}
}
角色地图:
using FluentNHibernate.Mapping;
using Models;
namespace NHibernate.Mapping
{
public class RoleMap : ClassMap<Role>
{
public RoleMap()
{
Table("Role");
Id(x => x.Id).GeneratedBy.GuidComb();
LazyLoad();
Map(x => x.Name).Column("Name");
}
}
}
CustomForeignKeyConvention:
using FluentNHibernate;
using FluentNHibernate.Conventions;
namespace NHibernate.Conventions
{
public class CustomForeignKeyConvention : ForeignKeyConvention
{
protected override string GetKeyName(Member property, System.Type type)
{
if (property == null)
{
return type.Name;
}
return property.Name;
}
}
}
会议工厂:
using FluentNHibernate.Cfg;
using FluentNHibernate.Cfg.Db;
using NHibernate.Conventions;
namespace NHibernate
{
public static class SessionFactory
{
private static ISessionFactory _sessionFactory;
public static ISessionFactory Instance
{
get
{
if (_sessionFactory == null)
{
_sessionFactory = CreateSessionFactory();
}
return _sessionFactory;
}
}
private static ISessionFactory CreateSessionFactory()
{
return Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2012
.ConnectionString(c => c.FromConnectionStringWithKey("DatabaseConnectionString")))
.Mappings(m =>
{
m.FluentMappings.Conventions.AddFromAssemblyOf<CustomForeignKeyConvention>();
m.FluentMappings.AddFromAssemblyOf<Models.EntityBase>();
})
.BuildSessionFactory();
}
}
}
WebService.cs
using System.Linq;
using System.Net;
using System.Web.Services;
using NHibernate;
using Models;
[WebService(Namespace = "http://LambdAlarm.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class LambdAlarmWebService : WebService
{
[WebMethod]
public HttpStatusCode Login(string username, string password)
{
var factory = SessionFactory.Instance;
var session = factory.OpenSession();
var result = session.QueryOver<User>().List<User>();
var login = result.Where(u => u.Username == username).Where(p => p.PasswordHash == password);
return HttpStatusCode.NotFound;
}
}
所以是的......这不是一件容易的事。我认为数据库中的外键关系与User和Role表有关。角色列应引用角色表中的Id。
请帮忙!

问题是References()
是指引用另一个实体,而不是类型。如果您想使用某种类型,则应使用Map(x => x.Role)
代替References(x => x.Role)
将User
更改为:
public class User : EntityBase
{
public virtual string Username { get; set; }
public virtual string PasswordHash { get; set; }
public virtual string Salt { get; set; }
public virtual Role Role { get; set; } //CHANGED HERE
public virtual string Token { get; set; }
public virtual DateTime TokenStamp { get; set; }
}
您的UserMap
:
public UserMap()
{
Table("User");
Id(x => x.Id).GeneratedBy.GuidComb();
LazyLoad();
References(x => x.Role).Column("Role");
Map(x => x.Username).Column("Username");
Map(x => x.PasswordHash).Column("PasswordHash").Not.Nullable();
Map(x => x.Salt).Column("Salt").Not.Nullable();
Map(x => x.Token).Column("Token").Not.Nullable();
Map(x => x.TokenStamp).Column("TokenStamp");
}
此外,在使用Fluent NHibernate进行映射时,没有理由指定列名。默认情况下,它只会使用您的媒体资源的名称,因此Map(x => x.Name).Column("Name").Not.Nullable()
之类的内容与Map(x => x.Name).Not.Nullable()
其他一些建议:
为您的映射创建基类以使其更容易:
public abstract class ClassMapBase<T> : ClassMap<T> where T: EntityBase
{
protected ClassMapBase()
{
Id(x => x.Id).Not.Nullable().GeneratedBy.GuidComb();
LazyLoad();
}
}
另外,我很惊讶NHibernate没有抱怨你Id
EntityBase
有一个公共制定者。它应该设置为受保护或私有。除非您希望它与实体名称不同,否则也无需指定您的表名称

虽然有正确答案,但我会让其他人认为有用的其他解决方案。当您的应用程序无法访问您的数据库时,会导致此错误。所以:
services.exe
并查看您的SQL Server是否正在运行答案 2 :(得分:0)
如果其他人遇到这种错误,请检查您的实体中是否存在虚拟关键字。例如:
<asp:Button ID="btSubmit" runat="server" Text ="Submit Email" OnClick="btSubmit_Click" OnClientClick="return confirm('Test');"/>
