Invited Talk: Hibernate Integration with AspectJ

Wednesday, March 16, 4:30 pm – 5:00 pm

Nicholas Lesiecki, VMS, Coauthor Mastering AspectJ

Abstract

Hibernate, though simpler in many respects than a heavyweight persistence container, demands more vigilance on the part of the developer: to manage sessions/transactions, to enlist persistent objects appropriately, and to manage relationships between persistent objects. This talk will describe a set of aspects VMS used in production to manage these issues and to reduce the development effort required to extend and maintain a Hibernate persistence model. Attendees will learn about:

• Declarative transactions managed with AspectJ
• Bidirectional relationship propagation
• Automatic enlistment of new persistent objects with the currently open session (along with an interesting solution to the problem of relationships initiated in the constructor)
• Flushing database changes automatically before query operations
• Implementing common persistence features with static crosscutting
