[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-1081) Generation of meta attributes for composite-id

[Norman Franke (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HBX-1081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43170#comment-43170 ] 

Norman Franke commented on HBX-1081:
------------------------------------

I second the vote for tableToMetaAttributesForCompositeId. That would be very, very useful. I use a ReverseEngineeringStrategy and a regeng.xml to generate the annotate POJOs directly without .hbm.xml files.

> The ReverseEngineeringStrategy has a method; "public Map tableToMetaAttributes(TableIdentifier tableIdentifier)"
> This method returns a Map of meta tags which will be put inside the class node of the hbm files that are generated.
> It would be a nice addition if we could have a method like this which placed meta tags inside the composite id node.
> the method could be called "public Map tableToMetaAttributesForCompositeId(TableIdentifier tableIdentifier)"
> An example of the problem is shown in the below example;
> <class name="XXX1" table="XXX1">
>         <meta attribute="generated-class">XXX1Base</meta>           <!-- this can be generated by tableToMetaAttributes() -->
>         <composite-id name="XXX2" class="XXX2">
>                 <meta attribute="generated-class">XXX2Base</meta>  <!-- this cannot be generated -->
>                 <key-property name="propertyXXX" type="int">
>                         <column name="ColoumnXXX" />
>                 </key-property>
>                 <key-property name="YYY" type="int">
>                         <column name="ColoumnYYY" />
>                 </key-property>
>         </composite-id>
>         ...
> </class>
