如何使用ColdFusion ORM映射基类？ [英] How do you map a base class using ColdFusion ORM?

问题描述

我有两个组件，一个基础 Entity 组件：

I have two components, a base Entity component:

<cfcomponent persistent="true">
    <cfproperty name="Id" fieldtype="id" generator="native">
</cfcomponent>

和一个 Client

<cfcomponent persistent="true" extends="Entity">
    <cfproperty name="FirstName">
    <cfproperty name="LastName">
</cfcomponent>

$ b < $ c>，我得到一个错误，说他们被映射为两个不同的表。我知道Hibernate有能力忽略一个基类，但我如何使用ColdFusion的标签，或者我必须回到HBM映射这个功能吗？

However, when I try to create an instance of Client, I get an error that says that they're being mapped as two different tables. I know Hibernate has the ability to ignore a base class, but how would I do it with ColdFusion's tags, or do I have to fall back to HBM mappings for this feature?

附录：删除实体中的 persistent =true无效，


Addendum: Removing the persistent="true" from Entity doesn't work either, Client will act as if it doesn't have an Id property if I do so.

推荐答案

在您的基础Entity类中尝试删除persistent =true并添加mappedSuperClass =true。

In your base "Entity" class try removing persistent="true" and adding mappedSuperClass="true".

<cfcomponent mappedSuperClass="true">
    <cfproperty name="Id" fieldtype="id" generator="native">
</cfcomponent>

您需要将9.0.1更新应用于ColdFusion。

You need to have applied the 9.0.1 update to ColdFusion.
