Question

我正在设置一个新的解决方案来映射已从Access数据库导入的SQL数据。 Auto Mappings对我定义的实体工作正常但我需要能够使用Fluent映射类型来访问.NotFound.Ignore扩展。

我在另一个项目中使用了完全相同的语法（我认为！），它运行正常。我是否犯了一个小学生错误导致“不支持的映射类型'IT.Classes.Entities.Admin'”？非常感谢任何帮助。

DDL：

CREATE TABLE [dbo].[Admin](
    [ID] [int] NOT NULL,
    [primaryEmail] [nvarchar](50) NULL,
    [secondaryEmail] [nvarchar](50) NULL,
    [highPriorityEmail] [nvarchar](50) NULL,
    [MobileEmail] [nvarchar](50) NULL,
    [EmailUser] [bit] NOT NULL,
    [HelpDeskMessage] [nvarchar](max) NULL
) ON [PRIMARY]

实体：

namespace IT.Classes.Entities
{
    public class Admin
    {
    public virtual bool EmailUser { get; set; }

    public virtual string HelpdeskMessage { get; set; }

    public virtual string HighPriorityEmail { get; set; }

    public virtual int Id { get; set; }

    public virtual string MobileEmail { get; set; }

    public virtual string PrimaryEmail { get; set; }

    public virtual string SecondaryEmail { get; set; }
    }
}

映射：

使用FluentNHibernate.Mapping; 使用IT.Classes.Entities;

namespace IT.Classes.Mappings
{
    public sealed class AdminMap : ClassMap<Admin>
    {
        public AdminMap()
        {
            this.Id(x => x.Id);
            this.Map(x => x.EmailUser);
            this.Map(x => x.HelpdeskMessage);
            this.Map(x => x.HighPriorityEmail);
            this.Map(x => x.MobileEmail);
            this.Map(x => x.PrimaryEmail);
            this.Map(x => x.SecondaryEmail);
        }
    }
}

会议工厂：

private static ISessionFactory CreateItHelpdeskSessionFactory()
{
    return
        Fluently.Configure().Database(
            MsSqlConfiguration.MsSql2008.ConnectionString(
                ConfigurationManager.ConnectionStrings["ITHelpdesk"].ConnectionString))
                .Mappings(m => m.FluentMappings.Add<Admin>())
                .Mappings(m => m.FluentMappings.Add<Applications>())
                .Mappings(m => m.FluentMappings.Add<Category>())
                .Mappings(m => m.FluentMappings.Add<Log>())
                .Mappings(m => m.FluentMappings.Add<Multipliers>())
                .Mappings(m => m.FluentMappings.Add<Os>())
                .Mappings(m => m.FluentMappings.Add<Priority>())
                .Mappings(m => m.FluentMappings.Add<Request>())
                .Mappings(m => m.FluentMappings.Add<Status>())
                .BuildSessionFactory();
}

修改

我以为我会导出自动映射以查看它们是否会在我的流畅映射中突出显示问题，但它们似乎是正确的：

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
  <class xmlns="urn:nhibernate-mapping-2.2" name="IT.Classes.Entities.Admin, ITClasses, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="`Admin`">

    <property name="EmailUser" type="System.Boolean, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">

在配置代码中，Fluent Mappings中提到的类型应该是 map classes ，而不是要映射的类。

即代替：

return
    Fluently.Configure().Database(
        MsSqlConfiguration.MsSql2008.ConnectionString(
            ConfigurationManager.ConnectionStrings["ITHelpdesk"].ConnectionString))
            .Mappings(m => m.FluentMappings.Add<Admin>())
            .Mappings(m => m.FluentMappings.Add<Applications>())
            .Mappings(m => m.FluentMappings.Add<Category>())
            .Mappings(m => m.FluentMappings.Add<Log>())
            .Mappings(m => m.FluentMappings.Add<Multipliers>())
            .Mappings(m => m.FluentMappings.Add<Os>())
            .Mappings(m => m.FluentMappings.Add<Priority>())
            .Mappings(m => m.FluentMappings.Add<Request>())
            .Mappings(m => m.FluentMappings.Add<Status>())
            .BuildSessionFactory();

你需要说：

return
    Fluently.Configure().Database(
        MsSqlConfiguration.MsSql2008.ConnectionString(
            ConfigurationManager.ConnectionStrings["ITHelpdesk"].ConnectionString))
            .Mappings(m => m.FluentMappings.Add<AdminMap>())
            .Mappings(m => m.FluentMappings.Add<ApplicationsMap>())
            .Mappings(m => m.FluentMappings.Add<CategoryMap>())
            .Mappings(m => m.FluentMappings.Add<LogMap>())
            .Mappings(m => m.FluentMappings.Add<MultipliersMap>())
            .Mappings(m => m.FluentMappings.Add<OsMap>())
            .Mappings(m => m.FluentMappings.Add<PriorityMap>())
            .Mappings(m => m.FluentMappings.Add<RequestMap>())
            .Mappings(m => m.FluentMappings.Add<StatusMap>())
            .BuildSessionFactory();

更好的是，为避免每个类映射都有单独的行，请使用.AddFromAssemblyOf＆lt;＆gt;（）方法，该方法使用反射添加来自给定程序集的所有类映射：

return
    Fluently.Configure().Database(
        MsSqlConfiguration.MsSql2008.ConnectionString(
            ConfigurationManager.ConnectionStrings["ITHelpdesk"].ConnectionString))
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<AdminMap>())
            .BuildSessionFactory();
