Class AbstractJpaRepository<ID extends Serializable,DomainModel extends IIdentifiable<ID>,PersistenceModel extends DomainModel>

java.lang.Object
  com.googlecode.jbp.jpa.AbstractJpaRepository<ID,DomainModel,PersistenceModel>

Type Parameters:

ID - The class of the identifier.

DomainModel - The domain interface of the persisted classes.

PersistenceModel - The persisted class, which implements the domain interface.

All Implemented Interfaces:

IRepository<ID,DomainModel>

public abstract class AbstractJpaRepository<ID extends Serializable,DomainModel extends IIdentifiable<ID>,PersistenceModel extends DomainModel>
extends Object
implements IRepository<ID,DomainModel>

Abstract data access object implemented using Hibernate. This abstract class should be extended by specific data access objects when Hibernate is to be used for persistence.

Note that @Transactional annotations are used here as Hibernate works with object graphs, thus multiple rows in multiple tables may be modified in a single method. Nevertheless don't forget that normally transaction should always be declared in the service layer.
