如何使用ColdFusion ORM映射基类？

本文介绍了如何使用ColdFusion ORM映射基类？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 29岁程序员，3月因学历无情被辞！ 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 ，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. 这篇关于如何使用ColdFusion ORM映射基类？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
