Hi all,
We're using HibernateTools 3.2.4.Beta1.

Because of some historic stuff, we need to reverseengineer *.hbm.xml and pojo's from a MS SQL DB.
We generate everthing with the ant task, provided by the hibernate tools

The default behaviour of hbm2java task is to generate one class per table.

What we need is a abstract class with all getter/setter of the table and a concrete subclass of the abstract class. (Like the EclipseTools with velocity) e.g.:



The BaseObject is no problem (added following to the hibernate.reveng.xml)


But how can we achieve the automatic generation of Abstract-Class and the concret class for each table/view ?
We have more then 300 tables, so we can't configure each table manually

Thanx
Jürgen

Hi Jürgen-

I've done what you're describing by using 2 custom templates, one that generates the abstract class and the other that generates the concrete class:

<!-- based on generated hbm.xml files, generate
abstract pojo instances using custom templates -->

<hbmtemplate
destdir="${root.dir}/generated"
filepattern="com/x/dao/Abstract{class-name}.java"
templatepath="${root.dir}/build/hibernate/template/abstract"
templateprefix="pojo/"
template="pojo/Pojo.ftl">
<property key="jdk5" value="true"/>
<property key="ejb3" value="false"/>
<property key="parentClass" value="com.wrigley.web.dao.DaoObject"/>
</hbmtemplate>

<!-- based on generated hbm.xml files, generate
concrete pojo instances using custom templates -->

<hbmtemplate
destdir="${root.dir}/generated"
filepattern="com/x/dao/{class-name}.java"
templatepath="${root.dir}/build/hibernate/template/concrete"
templateprefix="pojo/"
template="pojo/Pojo.ftl">
<property key="jdk5" value="true"/>
<property key="ejb3" value="false"/>
</hbmtemplate>
</hibernatetool>


As you can see, I use a 'workspace' directory called generated as the target for all the assets generated during reverse engineering. When the task wraps up I have 2 ant copy calls, one which over writes and selects only those assets I want overwritten (like the hbm.xml files and the abstract classes) and another copy that does not write for the concrete classes. The final step is of course to delete the generated directory.

HTH,

Jim

It's funny. Max and I have been talking about largely the same thing in another thread (generating annotated pojos).

I am wanting to do this, but with annotated pojos, so the custom templates are a bit more difficult. Also, I wanted to use built-in templates, so that I don't have to keep mine up, I can just get updates from the project.
