nhibernate - Fluent Nhibernate 复合键不生成引用实体的连接

Question

我有一个带有复合键的映射，如下所示:

CompositeId()
            .KeyReference(x => x.CreatedBy, "member_key")
            .KeyReference(x => x.Box, "box_key");

这适用于简单的获取和插入，但它不会生成与引用中提到的表的连接，我尝试将它们用作查询的一部分。

所以这:

return _sessionFactory.GetCurrentSession().QueryOver<BoxMember>()
            .Where(x => x.Box.Id == boxId)
            .Where(x => x.Member.DeletedDate == null)
            .Fetch(x => x.Box).Eager
            .Fetch(x => x.CreatedBy).Eager
            .List();

生成以下 SQL:

    SELECT this_.member_key     as member1_5_0_,
       this_.box_key        as box2_5_0_
FROM   box_member this_
WHERE  this_.box_key = '2750e160-ba72-4a70-b554-9fd600e3cfd0' /* @p0 */
and    m1_.deleted_date is null;

Answer 1

我有完全相同的问题。添加引用映射有帮助，但无论如何这个问题没有意义:

尝试这个:

CompositeId() 
            .KeyReference(x => x.CreatedBy, "member_key") 
            .KeyReference(x => x.Box, "box_key"); 
Reference(x => x.CreatedBy);
Reference(x => x.Box);
