hibernate - ColdFusion ORMmappedSuperClass.hbmxml 有太多字段

Question

当我运行下面的代码时，ColdFusion 9(更新到最新)为 billingaddress cfc 生成错误的(恕我直言)XML 文件。即，它包括base.cfc的属性。这是一个错误，我错过了什么，还是这是预期的行为？

应用程序.cfc

component
{
  this.name = "ormtest";
  this.mappings["/model"] = expandPath( "./model" );
  this.datasource = "mingo";
  this.ormEnabled = true;
  this.ormSettings = {
    CFCLocation = "/model",
    dbcreate = "dropcreate",
    savemapping = true
  };

  function onRequestStart()
  {
    ormreload();    
  }
}

base.cfc

component mappedSuperClass = "true"
{
  property fieldType = "id"     name = "id" generator = "guid";
  property fieldType = "column" name = "deleted" ORMType = "boolean" default = "0" notnull = "true";
  property fieldType = "column" name = "sortorder" ORMType = "integer";
  property fieldType = "column" name = "label";
}

地址.cfc

component extends = "model.base"
          persistent = "true"
          table="address"
          discriminatorColumn = "discriminator"
{
  property name = "address";
}

账单地址.cfc

component extends = "model.address"
          persistent = "true"
          table="address"
          discriminatorValue = "billingaddress"
{}

账单地址.hbmxml

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
                                   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <subclass discriminator-value="billingaddress"
        entity-name="billingaddress" extends="cfc:model.address"
        lazy="true" name="cfc:model.billingaddress">
        <property name="deleted" type="boolean">
            <column name="deleted" not-null="true"/>
        </property>
        <property name="sortorder" type="integer">
            <column name="sortorder"/>
        </property>
        <property name="label" type="string">
            <column name="label"/>
        </property>
    </subclass>
</hibernate-mapping>

Answer 1

这就是我所期望的行为。扩展组件将导致子组件继承父组件的属性。当您有多个继承级别时，它将一路继承到链上。

阅读您的评论后，我进一步研究了这一点。据我所知，您描述的问题首先出现在CF9 Cumulative Hot Fix 2中，可能(只是在这里猜测)由于此错误修复:

ColdFusion ORM does not maintain the column order correctly when the CFC extends a base cfc with an attribute mappedSuperclass set to true.

引用的错误是#83474，我似乎无法在 Adob​​e 的错误跟踪器上找到它。它反射(reflect)在 Elliot Sprehn 的网站上，here .

我还在这里找到了关于同一问题的另一个问题:Wrong HBM mappings when using a mapped superclass in an inheritance graph for ColdFusion 9.0.1 Hotfix 2 。该问题中报告的解决方法是手动编辑 hbmxml 文件。

长话短说，它看起来像是一个 CF bug。我研究了大约 20 分钟，除了手动编辑 hbmxml 文件以删除 billingaddress.cfc 中的额外属性之外，无法找到解决方法。
