如何在 NHibernate 中映射聚合关系的多个根类型？
假设我有一个 Child 类，它包含在不同的其他类中（本例中为 ParentA 和 ParentB）。以下简单案例演示了一个简单模型，其中 ParentA 和 ParentB 都包含一组 Child 对象。
public class ParentA
{
public virtual ISet<Child> Children { get; set; }
}
public class ParentB
{
public virtual ISet<Child> Children { get; set; }
}
public class Child
{
}
在这个简单的情况下，从父级到子级的导航没有问题。但现在我希望能够导航到父级。通常我会引入一个接口 IParent）
public class ParentA: IParent
{
public virtual ISet<Child> Children { get; set; }
}
public class ParentB
{
public virtual ISet<Child> Children { get; set; }
}
public class Child
{
public virtual IParent Parent { get; set; }
}
现在的问题是如何在 NHibernate 中映射这样的关系？
Let's say I have a class Child which is contained in different other classes (ParentA and ParentB in this example). The following simple case demonstrates a simple model where ParentA and ParentB both contain a set of Child objects.
public class ParentA
{
public virtual ISet<Child> Children { get; set; }
}
public class ParentB
{
public virtual ISet<Child> Children { get; set; }
}
public class Child
{
}
Navigation from parent to child is no problem in this simple case. But now I want to be able to navigate to the parent. Typically I would introduce an interface IParent)
public class ParentA: IParent
{
public virtual ISet<Child> Children { get; set; }
}
public class ParentB
{
public virtual ISet<Child> Children { get; set; }
}
public class Child
{
public virtual IParent Parent { get; set; }
}
The question now is how would you map such a relationship in NHibernate?

Ayende 有一个示例 NHibernate 博客模型。
Tag实体通过名为Entity的属性对其父级进行引用。Entity的类型是object，它被映射为Post或Blog。它可能就是您正在寻找的。模型中的所有文件此处
