#Entity listeners

Entity listeners are used to react on certain events that can occur during managing the entities. In JPA there are 7 events defined:

@PostLoad
@PostPersist
@PostRemove
@PostUpdate
@PrePersist
@PreRemove
@PreUpdate

Those annotations can be applied to methods of an entity class, a mapped superclass, or a callback listener class. A single class must not have more than one lifecycle callback method for the same lifecy- cle event.

Default entity listeners — entity listeners that apply to all entities in the persistence unit. They can be specified by means of the XML descriptor.

A runtime exception thrown by a callback method that executes within a transaction causes that transaction to be marked for rollback. No further lifecycle callback methods will be invoked after a runtime exception is thrown.
