Method Details

onCreation

@TransactionalEventListener(phase=BEFORE_COMMIT)
public void onCreation(ResourceCreated event)

Manages metadata about a resource just created. This listener is executed before the current transaction is committed, so that it can add metadata within the same transaction that created a resource.

Parameters:

event -

onUpdate

@TransactionalEventListener(phase=BEFORE_COMMIT)
public void onUpdate(ResourceModified event)

Manages metadata about a resource that was updated. This listener is executed before the current transaction is committed, so that it can add metadata within the same transaction that updated a resource.

Parameters:

event -

onDeletion

@EventListener
public void onDeletion(ResourceDeleted event)

Manages metadata about a resource that was created. This listener (which is not transactional) is executed Immediately as the event is first published. Indeed, deletions are published before they actually occur, because otherwise all 1st level statements of the deleted resource would have been removed from the repository.

Parameters:

event -
