NHibernate:无法解析继承的id属性 [英] NHibernate: cannot resolve inherited id property

问题描述

我的实体定义如下:

public class Foo : Entity<Foo.FooId>
{
    public class FooId
    {
        public virtual String Bar { get; protected internal set; }
        public virtual Int32 Buzz { get; protected internal set; }
    }

    // ...
}

这是基类:

public abstract class Entity<T> : IEquatable<Entity<T>>
{
    public virtual T Id { get; protected internal set; }

    // ...
}

我将"Id"属性映射为复合键"，因此我添加了以下映射类:

I'm going to map the "Id" property as a "composite key", so I've added the following mapping class:

public class FooMap : ClassMapping<Foo>
{
    public FooMap()
    {
        ComponentAsId(x => x.Id, m =>
        {
            m.Property(p => p.Bar);
            m.Property(p => p.Buzz);
        });
    }
}

这一切都很好，但是以下查询尝试出现错误:

And that's all pretty nice, but I get an error with the following querying attempt:

session.QueryOver<Foo>()
       .Where(m => m.Id.Bar == "a" &&
                   m.Id.Buzz == 2).List();

我得到的错误是: NHibernate.QueryException:无法解析属性:Id of:Foo

这很奇怪，因为通过删除基类并将所有内容封装在"Foo"中，它就像一个魅力. 预先感谢.

It's quite strange, because by removing the base class and encapsulating everything within "Foo", it works like a charm. Thanks in advance.
