OFBiz 中定义的数据资源实体在哪里？

Question

正在研究OFBiz框架，有一个疑问

我找到了创建数据资源的服务。 (applications/content/src/main/java/org/apache/ofbiz/content/data/DataServices.java)

但我找不到定义数据资源实体的位置。通常实体在 entitydef 目录下的 entitymodel.xml 文件中定义。但是，内容应用程序没有 entitymodel.xml 文件。只有 eecas.xml 文件。

directory tree

<entity-eca xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="http://ofbiz.apache.org/dtds/entity-eca.xsd">

<!-- If the text in the database has changed for the data resource, we need to clear out anything depending on this cached value -->
<eca entity="ElectronicText" operation="store-remove" event="return">
    <action service="clearAssociatedRenderCache" mode="sync" />
</eca>

<!-- Content Keyword Indexing ECAs -->
<eca entity="Content" operation="create" event="return">
    <action service="indexContentKeywords" mode="sync" value-attr="contentInstance"/>
</eca>
<eca entity="Content" operation="store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>
<eca entity="ContentAttribute" operation="create-store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>
<eca entity="ContentMetaData" operation="create-store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>
<eca entity="ContentRole" operation="create-store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>
<eca entity="ProductContent" operation="create-store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>
<eca entity="ProductCategoryContent" operation="create-store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>
<eca entity="PartyContent" operation="create-store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>
<eca entity="WebSiteContent" operation="create-store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>
<eca entity="WorkEffortContent" operation="create-store" event="return">
    <action service="indexContentKeywords" mode="sync"/>
</eca>

而且这个 eecas.xml 文件似乎与数据资源无关。明明是存在的实体，可是到底定义在哪里？如果您能给我答案，我将不胜感激。

您可以在 https://github.com/apache/ofbiz-framework/blob/trunk/applications/datamodel/entitydef/content-entitymodel.xml 中找到它查找：

<实体实体名称="DataResource"

OFBiz 中定义的数据资源实体在哪里？

Where is DataResource Entity defined in OFBiz?

java
