Package org.keycloak.models.map.storage.jpa.hibernate.listeners

Class JpaAutoFlushListener

java.lang.Object
org.hibernate.event.internal.AbstractFlushingEventListener
org.hibernate.event.internal.DefaultAutoFlushEventListener
org.keycloak.models.map.storage.jpa.hibernate.listeners.JpaAutoFlushListener
All Implemented Interfaces:
org.hibernate.event.service.spi.JpaBootstrapSensitive, org.hibernate.event.spi.AutoFlushEventListener
public class JpaAutoFlushListener extends org.hibernate.event.internal.DefaultAutoFlushEventListener
Extends Hibernate's DefaultAutoFlushEventListener to always flush queued inserts to allow correct handling of orphans of that entities in the same transactions, and also to clear a session-level query cache.

If they wouldn't be flushed, they won't be orphaned (at least not in Hibernate 5.3.24.Final). This class copies over all functionality of the base class that can't be overwritten via inheritance. This is being tracked as part of keycloak/keycloak#11666.

This also clears the JPA map store query level cache for the JpaMapStorage whenever there is some data written to the database.
