Question

我遇到Fluent Nhibernate的问题：错误是“无法解析MailHeader类的Property MailHeader。

问题与实体“MailHeader”内的集合有关，如果我删除集合，则异常消失，但我想要这些集合！提前谢谢。

所涉及的实体是：

    public class MailHeader : Entity
{
    public MailHeader()
    {
        MailRecipientUsers = new List<MailRecipientUser>();
        MailsDeleted = new List<MailDeleted>();

    }

    [Required]
    public virtual string Subject { get; set; }
    public virtual IList<MailRecipientUser> MailRecipientUsers { get; protected set; }
    public virtual IList<MailDeleted> MailsDeleted { get; protected set; }

}

 public class Mail : Entity
{
    public Mail()
    {
        Creation = DateTime.Now;
        MailHeader = new MailHeader();
    }

    [Required]
    public virtual string BodyText { get; set; }
    [Required]
    public virtual MailHeader MailHeader { get; set; }

    public virtual Mail Parent { get; set; }

    [Required]
    public virtual User From { get; set; }


    public virtual Mail Child { get; set; }

    [DataType(DataType.Date)]
    public virtual DateTime Creation { get; set; }
    //[Required]
    //public virtual MailType MailType { get; set; }
}

 public class MailRecipientUser : Entity
{
    [Required, DomainSignature]
    public virtual MailHeader MailHeader { get; set; }

    [Required, DomainSignature]
    public virtual User User { get; set; }

}
public class MailDeleted : Entity
{
    public MailDeleted()
    {
    }

    [DomainSignature,Required]
    public virtual MailHeader MailHeader { get; set; }
    [DomainSignature, Required]
    public virtual User User { get; set; }

}

映射：

public class MailHeaderMap : IAutoMappingOverride<MailHeader>
{
    public void Override(AutoMap<MailHeader> mapping)
    {
        mapping.HasMany(x => x.MailRecipientUsers)
            .Inverse()
            .Cascade.AllDeleteOrphan();

        mapping.HasMany(x => x.MailsDeleted)
            .Inverse()
            .Cascade.AllDeleteOrphan();

    }
}

 public class MailMap : IAutoMappingOverride<Mail>
{
    public void Override(AutoMap<Mail> mapping)
    {
        mapping.References(x => x.From);
        mapping.References(x => x.Parent);
        mapping.References(x => x.MailHeader);

        mapping.HasOne(e => e.Child)
            .WithForeignKey()
            .PropertyRef(a => a.Parent)
            .Cascade.All();
    }
}
public class MailRecipientUserMap : IAutoMappingOverride<MailRecipientUser>
{
    public void Override(AutoMap<MailRecipientUser> mapping)
    {
        mapping.References(x => x.MailHeader);
        mapping.References(x => x.User);
    }
}
public class MailDeletedMap : IAutoMappingOverride<MailDeleted>
{
    public void Override(AutoMap<MailDeleted> mapping)
    {
        mapping.References(x => x.MailHeader);
        mapping.References(x => x.User);
    }
}
