@MappedSuperclass
public abstract class TimestampedBaseEntity<I extends Comparable<I> & Serializable>
extends BaseEntity<I>
implements Timestamped

Mapped superclass for timestamped entity. It extends from BaseEntity. It specifies two timestamp columns, named "created" and "lastModified". The Id column needs to be manually taken care of. On pre persist, the both columns will be set to current timestamp. On pre update, the "lastModified" column will be set to current timestamp, unless skipAdjustLastModified() is called beforehand.
