org.omnifaces.persistence.model

Class BaseEntity<I extends Comparable<I> & Serializable>

java.lang.Object

org.omnifaces.persistence.model.BaseEntity<I>

Type Parameters:

I - The generic ID type, usually Long.

All Implemented Interfaces:

Serializable, Comparable<BaseEntity<I>>, Identifiable<I>

Direct Known Subclasses:

TimestampedEntity

@MappedSuperclass
public abstract class BaseEntity<I extends Comparable<I> & Serializable>
extends Object
implements Comparable<BaseEntity<I>>, Identifiable<I>, Serializable

Let all your entities extend from this. Then you can make use of BaseEntityService. This mapped superclass already automatically takes care of the id column.

There are two more mapped superclasses which may also be of interest.

• TimestampedEntity - extends BaseEntity with created and lastModified columns and automatically takes care of them.
• VersionedEntity - extends TimestampedEntity with a @Version column.
