Reveng.hibernate.xml meta tag attributes are visible in hbm2java ftl templates for auto-generated @Embeddable class?

Hibernate Tools

Hello, everyone,

I am using reverse engineering Hibernate (hbm2java) via Maven and hibernate.reveng.xml.
One of my tables has a primary key consisting of two fields.

I would like to add a custom annotation to one of these fields.

<table schema=“biva” name=“tbiv09_con_eve” class=“it.test.prod.entity.EventConnected”>
     <meta attribute=“test”>my value</meta>
</table>

Since I use the meta tag to customize the generation of my entity files, using modified ftl templates (taken from hibernate-tools-orm-X.X.x.Final.jar) I would have liked to do that here as well.

But unfortunately I have a problem, I can’t display or check for the presence of a meta tag within an autogenerated class annotated with @Embeddable, for example EventConnectedId

If I add this line in PojoFields.ftl

==><#if pojo.hasMetaAttribute(“test”)>OK!</#if><==

And try to check the generated entity EventConnected, I have correctly:

==>OK!<==

But, if I check EventConnectedId:

==><==

Is it a bug? Is it an intended behavior?
Is there a way to be able to use the meta tag in this context?

Thanks,
Francesco

If you are using Hibernate for reverse engineering (hbm2java) and your table has a composite primary key consisting of two fields, don’t worry.
Create a class that contains all the fields from your Entity class. Add the @Id annotation to each field in the class. This method is easier if you don’t want to create a separate class for the key.

Remember to configure hibernate.reveng.xml to generate the correct annotations. This file contains special tags for configuring table and key processing.
