[jboss-jira] [JBoss JIRA] (WFLY-1186) Create JPA service callback for invoking database migration

Thu May 30 12:52:55 EDT 2013

    [ https://issues.jboss.org/browse/WFLY-1186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12778298#comment-12778298 ] 

Scott Marlow commented on WFLY-1186:
------------------------------------

[~anilarora], the JPA 2.1 specifications outline the new capabilities that will be in every JPA 2.1 persistence provider implementation (e.g. Hibernate 4.3.0).

There is a JPA 2.1 way to generate scripts but also to specify the name of a DDL/DML SQL script to be executed.

Exactly, how your/others needs are addressed by the JPA 2.1 specification, is open at this point.  If you want to get involved with *scratching* your "database migration" itch, using the new JPA 2.1 specification features, that would be great.

> Looking for a simple callback/listener mechanism so that we can invoke a database migration script before JPA persistent unit starts up and runs the Hibernate schema validation mechanism.
> Ideally, there would be a property within the persistence.xml that indicates which class to call.  It would also pass in/inject the datasource that is being used for the persistence unit. 
> Essentially, this would solve the lack of migration support in Hibernate itself.
