I am using Orika to map my Hibernate entities to DTO objects in web service calls. These entities have @OneToMany and @ManyToOne relationships in them for parent-child relations. Additionally, I am using Spring JPA to create these entities.
When mapping a Hibernate entity to a POJO DTO class, the map() method causes the loading of all lazy-loaded attributes.
@Entity
@Table(name="folders")
public class FolderEntity {
@Id
@GeneratedValue
private int id;
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="consumerId")
private ConsumerEntity consumer;
public class Folder
private int id;
private User consumer;
Folder folder = mapper.map(some_folder_entity, Folder.class);
In this case, the consumer attribute mapping causes Hibernate to load the child, which is not what I want.
I though the HibernateUnenhanceStrategy was meant to resolve this issue by removing the Hibernate proxy but it does not, or I am doing it wrong.
@Component
public class MapperFacadeFactory implements FactoryBean<MapperFacade> {
public MapperFacade getObject() throws Exception {
DefaultMapperFactory.Builder factoryBuilder = new DefaultMapperFactory.Builder();
factoryBuilder.unenhanceStrategy(new HibernateUnenhanceStrategy());
DefaultMapperFactory factory = factoryBuilder.build();
MapperFacade facade = factory.getMapperFacade();
return facade;
}
I realize I can exclude fields from the mapping configuration, but I want the children potentially in some web service calls but only want to high level parent attributes in other web service calls.
I believe I could create a CustomMapper to resolve this issue myself but before I go down that road I want to make sure I am not missing something built into Orika.
Thanks.
