本文介绍了NHibernate:无法解析继承的id属性的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
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.
