FluentNHibernate多对一引用,其中外键不是主键,列名称不同

我一直坐在这里一个小时试图解决这个问题......

我有2个表(缩写):

CREATE TABLE TRUST 
(
TRUSTID NUMBER NOT NULL,
ACCTNBR VARCHAR(25) NOT NULL
)
CONSTRAINT TRUST_PK PRIMARY KEY (TRUSTID)

CREATE TABLE ACCOUNTHISTORY
(
ID NUMBER NOT NULL,
ACCOUNTNUMBER VARCHAR(25) NOT NULL,
TRANSAMT NUMBER(38,2) NOT NULL
POSTINGDATE DATE NOT NULL
)
CONSTRAINT ACCOUNTHISTORY_PK PRIMARY KEY (ID)

我有2个类基本上反映了这些:

public class Trust
{
    public virtual int Id {get; set;}
    public virtual string AccountNumber { get; set; }

}

public class AccountHistory
{
    public virtual int Id { get; set; }
    public virtual Trust Trust {get; set;}
    public virtual DateTime PostingDate { get; set; }
    public virtual decimal IncomeAmount { get; set; }

}

如何在FluentNHibernate中执行多对一映射以使AccountHistory具有信任？具体来说,由于它与TRUSTID的Trust主键不同,并且它所引用的列的名称也不同(ACCTNBR与ACCOUNTNUMBER).这是我到目前为止 - 我如何在AccountHistoryMap上做引用信任？

public class TrustMap : ClassMap
{
    public TrustMap()
    {
        Table("TRUST");
        Id(x => x.Id).Column("TRUSTID");
        Map(x => x.AccountNumber).Column("ACCTNBR");
    }
}

public class AccountHistoryMap : ClassMap
{
    public AccountHistoryMap()
    {
        Table("TRUSTACCTGHISTORY");
        Id (x=>x.Id).Column("ID");
        References(x => x.Trust).Column("ACCOUNTNUMBER").ForeignKey("ACCTNBR").Fetch.Join();
        Map(x => x.PostingDate).Column("POSTINGDATE");
        );

我已经尝试了上述几行的一些不同变体,但无法获得任何工作 - 它会回收AccountHistory数据和Trust的代理; 但它没有给出具有给定标识符的Trust行.

这必须简单.任何人？

提前致谢.

你需要使用property-ref:

public class AccountHistoryMap : ClassMap
{
    public AccountHistoryMap()
    {
        Table("TRUSTACCTGHISTORY");
        Id (x=>x.Id).Column("ID");
        References(x => x.Trust, "ACCOUNTNUMBER").PropertyRef("ACCTNBR").Fetch.Join();
        Map(x => x.PostingDate).Column("POSTINGDATE");
    }
}
