[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2035) Generate hibernate.cfg file from used persisted entities only

Generate hibernate.cfg file from used persisted entities only ------------------------------------------------------------- Key: HHH-2035 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2035 Project: Hibernate3 Type: New Feature

Components: core Environment: Hibernate 3.x + Hibernate annotations Reporter: Holger Haag Priority: Minor Attachments: TwoPhaseLoad-writeUsedPersisters.patch, hibernate-template.cfg.xml Original post from Hibernate forum: http://forum.hibernate.org/viewtopic.php?t=963888 The patch allows to call a new method TwoPhaseLoad.writeUsedPersisters which will generate a complete hibernate.cfg configuration file containing only the entities which have been persisted so far. The rationale behind this is that for unit test cases it is often sufficient - and much faster - to initialize hibernate with only a subset of all persisted classes, but it is cumbersome to find out which subset is the smallest possible. Attached is a SVN patch for the latest SVN trunk and a sample template file. Feel free to modify/put it into the hibernate code in any way you want, I think it can increase productivity - startup times for my test cases have dropped by 10 seconds. Please note that this patch will only work if you use Hibernate annotations since the generated XML file only contains class, not column mappings.
