/**
 * JPA entity listener to capture auditing information on persiting and updating entities. To get this one flying be
 * sure you configure it as entity listener in your {@code orm.xml} as follows:
 * 
 * <pre>
 * &lt;persistence-unit-metadata&gt;
 *     &lt;persistence-unit-defaults&gt;
 *         &lt;entity-listeners&gt;
 *             &lt;entity-listener class="org.springframework.data.jpa.domain.support.AuditingEntityListener" /&gt;

 *     &lt;/persistence-unit-defaults&gt;
 * &lt;/persistence-unit-metadata&gt;
 * </pre>
 * 
 * After that it's just a matter of activating auditing in your Spring config:
 * 
 * <pre>
 * &#064;Configuration
 * &#064;EnableJpaAuditing
 * class ApplicationConfig {
 * 
 * }
 * </pre>
 * 
 * <pre>
 * &lt;jpa:auditing auditor-aware-ref="yourAuditorAwarebean" /&gt;
