• The supported lifecycle events are PrePersist, PostPersist, PreRemove, PostRemove, PreUpdate, PostUpdate, and PostLoad
• An entity may define its own lifecycle callback methods (subclasses my override)

Callback Methods Example

• An entity listener may be used to monitor lifecycle events
• Entity listeners are invoked before entity callback methods (hierarchy is observed)

Entity Listener Example

• Entity listeners can be "excluded" by subclasses
