Optimistic Locking in Hibernate by default

Question

I have one question about optimistic locking in Hibernate. I am trying to go deep inside optimistic locking with Hibernate, but I have one doubt. Hibernate uses version appr

Answer 1

@axtavt, you right, but question about how hibernate implement optimistic locking without @Version column.

Today four OptimisticLockType options available:

/**
 * Perform no optimistic locking.
 */
NONE,
/**
 * Perform optimistic locking using a dedicated version column.
 *
 * @see javax.persistence.Version
 */
VERSION,
/**
 * Perform optimistic locking based on *dirty* fields as part of an expanded WHERE clause restriction for the
 * UPDATE/DELETE SQL statement.
 */
DIRTY,
/**
 * Perform optimistic locking based on *all* fields as part of an expanded WHERE clause restriction for the
 * UPDATE/DELETE SQL statement.
 */
ALL

I think this is enough to answer the original question.
