Persistent vs. Saved: Delving into Hibernate's session.persist() and session.save()

Hibernate provides two distinct methods, session.persist() and session.save(), to manage object states within the persistence context. While they share the common goal of making objects persistent, they differ in their specific behaviors and use cases.

Understanding session.persist()

  • Well-Defined Purpose: persist() explicitly makes transient instances persistent.
  • Identifier Assignment: It may not assign an identifier value immediately but does so during flush time.
  • Transaction Bounds: persist() avoids executing INSERT statements outside transaction boundaries, maintaining consistency within long-lived conversations.

Examining session.save()

  • Identifier Assignment: save() ensures immediate identifier assignment, potentially executing INSERT statements outside transaction boundaries.
  • Importance in Transaction Management: This behavior can be problematic in long-running conversations with an extended Session/persistence context.

Summary

Both persist() and save() are crucial methods in Hibernate's object management. persist() offers well-defined behavior for making transient instances persistent, while save() focuses on immediate identifier assignment. Choosing the appropriate method depends on the specific needs of the application and the desired persistence behavior within transaction boundaries.
