Class TransientReferenceResolvingInterceptor

java.lang.Object
com.broadleafcommerce.common.jpa.interceptor.TransientReferenceResolvingInterceptor
All Implemented Interfaces:
Serializable, org.hibernate.Interceptor
public class TransientReferenceResolvingInterceptor extends Object implements org.hibernate.Interceptor, Serializable
A low-level Hibernate interceptor that detects detached or transient entity references containing an ID within a parent entity being saved or updated.

When found, it automatically resolves and replaces the transient entity reference with an active, managed reference (proxy) from the current persistence context to avoid TransientPropertyValueException.

    • isTransient

      public Boolean isTransient(Object entity)
      Distinguishes transient (new) from detached (already persisted) entities without using Hibernate's getDatabaseSnapshot() fallback.

      Under Hibernate 7 that snapshot load builds an embeddable result with no owning entity initializer, so any @Parent parent-injection embeddable -- such as the tracking embeddable present on every tracked entity -- fails with "Injection of parent instance into embeddable result is not possible". Hibernate reaches that path when checking whether an assigned-id @ManyToOne reference is transient before an insert. By answering definitively here (using a normal, snapshot-safe load-by-id), Hibernate never falls through to the crashing snapshot query.

      Specified by:
      isTransient in interface org.hibernate.Interceptor
      Returns:
      FALSE if the entity already exists (managed or found in the database), TRUE if it is brand new, or null to defer to Hibernate's default when this interceptor cannot make a determination.
