表X中的关联引用了未映射的类：System.Guid [英] An association from the table X refers to an unmapped class: System.Guid

问题描述

我有这个课程：

公共类AttachmentLocation 
 {
 #region properties 
 
 public virtual Guid UserId {得到;组; } 
 
 public virtual Guid LocationId {get;组; } 
 
 public virtual long IndexInLocation {get;组; } 
 
 #endregion 
 
 #region包含外来对象
 
 public virtual Attachment Attachment {get;组; } 
 
 #endregion 
 
 
 #region方法需要覆盖CompositeId 
 
公共覆盖bool Equals（object obj）
 {
 if（obj == null）
返回false; 
 var t = obj as AttachmentLocation; 
 if（t == null）
返回false; 
 if（UserId == t.UserId&& LocationId == t.LocationId&&& Attachment.Id == t.Attachment.Id）
 return true; 
返回false; 
} 
 
公共覆盖int GetHashCode（）
 {
 return（UserId +|+ LocationId +|+ Attachment.Id）.GetHashCode（） ; 
} 
 
 #endregion 
 
} 
 

我有这个Fluent地图：

公共类AttachmentLocaionMap：ClassMap< attachmentlocation> 
 {
 public AttachmentLocaionMap（）
 {
 Table（Metadata_AttachmentLocation）; 
 CompositeId（）
 .KeyReference（x => x.UserId，UserId）
 .KeyReference（x => x.Attachment.Id，AttachmentId）
 .KeyReference（x => x.LocationId，LocationId）; 
 Map（x => x.IndexInLocation）.Not.Nullable（）; 
 Map（x => x.LocationId）.Not.Nullable（）; 
 
 HasOne（x => x.Attachment）; 
} 
}< / attachmentlocation> 
 

我注册：

 SessionFactory = Fluently.Configure（配置）.Mappings（m => 
 {
 m.FluentMappings.AddFromAssemblyOf< attachmentlocaionmap>（）; 
 m.FluentMappings.AddFromAssemblyOf< frienddetailsmap> （）; 
}）。BuildSessionFactory（）;< / frienddetailsmap>< / attachmentlocaionmap> 
 

我收到此运行时错误：

如何解决这个问题？



TIA

解决方案

我也有类似的问题，我对这个hibernate&流利的休眠。



我的表架构如下所示

  CREATE   TABLE  [dbo]。[MyChildImmunisations]（
 [Child_id] [ int ]  NOT   NULL ，
 [Schedule_id] [ int ]  NOT   NULL ，
 [状态] [ int ]  NOT   NULL ，
  CONSTRAINT  [PK_MyChildImmunisations]  PRIMARY   KEY   CLUSTERED  
（
 [Child_id]  ASC ，
 [Schedule_id]  ASC  
））

我的映射类代码li ke下面。

  protected  MyChildImmunisationMap（ string  tableName）
 {
 Table（tableName）; 
 
 CompositeId（）
 .KeyReference（ci = >  ci.Child.Id，  Child_id）
 .KeyReference（ci = >  ci .Schedule.Id，  Schedule_Id）; 
 
地图（ci = >  ci.Status）.CustomType< childimmunisationstatus>（）; 
} < /   childimmunisationstatus  > < /跨度> 

I have this class:

public class AttachmentLocation
{
    #region properties

    public virtual Guid UserId { get; set; }

    public virtual Guid LocationId { get; set; }

    public virtual long IndexInLocation { get; set; }

    #endregion

    #region contained foreign objects

    public virtual Attachment Attachment { get; set; }

    #endregion


    #region Methods need to override for CompositeId

    public override bool Equals(object obj)
    {
        if (obj == null)
            return false;
        var t = obj as AttachmentLocation;
        if (t == null)
            return false;
        if (UserId == t.UserId && LocationId == t.LocationId && Attachment.Id == t.Attachment.Id)
            return true;
        return false;
    }

    public override int GetHashCode()
    {
        return (UserId + "|" + LocationId + "|" + Attachment.Id).GetHashCode();
    }

    #endregion

}

I have this Fluent Mapping:

public class AttachmentLocaionMap : ClassMap<attachmentlocation>
{
    public AttachmentLocaionMap()
    {
        Table("Metadata_AttachmentLocation");
        CompositeId()
            .KeyReference(x => x.UserId, "UserId")
            .KeyReference(x => x.Attachment.Id, "AttachmentId")
            .KeyReference(x => x.LocationId, "LocationId");
        Map(x => x.IndexInLocation).Not.Nullable();
        Map(x => x.LocationId).Not.Nullable();

        HasOne(x => x.Attachment);
    }
}</attachmentlocation>

which I register:

SessionFactory = Fluently.Configure(configuration).Mappings(m =>
{
    m.FluentMappings.AddFromAssemblyOf<attachmentlocaionmap>();
    m.FluentMappings.AddFromAssemblyOf<frienddetailsmap>();
}).BuildSessionFactory();</frienddetailsmap></attachmentlocaionmap>

I get this runtime error:

How can I fix that?

TIA

解决方案

I also have similar problem, I am very much new to this hibernate & fluent hibernate.

My table schema is like below

CREATE TABLE [dbo].[MyChildImmunisations](
	[Child_id] [int] NOT NULL,
	[Schedule_id] [int] NOT NULL,
	[Status] [int] NOT NULL,
 CONSTRAINT [PK_MyChildImmunisations] PRIMARY KEY CLUSTERED 
(
	[Child_id] ASC,
	[Schedule_id] ASC
))

My mapping class code like below.

protected MyChildImmunisationMap(string tableName)
        {
            Table(tableName);

            CompositeId()
                .KeyReference(ci => ci.Child.Id, "Child_id")
                .KeyReference(ci => ci.Schedule.Id, "Schedule_Id");

            Map(ci => ci.Status).CustomType<childimmunisationstatus>();
        }</childimmunisationstatus>
