I have a problem with EAGERs relationships in a big application. Some entities in this application have EAGER
associations with other entities. This become "poison" in some functionalities.
Now my team needs to optimize this functionalities, but we cannot change the fetch type to LAZY, because we would need to refactor the whole application.
So, my question: Is there a way to do a specific query ignoring the EAGERs associations in my returned entity?
Example: when a I have this entity Person, I would like to not bring the address list when I do a query to find a Person.
@Entity
public class Person {
@Column
private String name;
@OneToMany(fetch=FetchType.EAGER)
private List<String> address;
}
Query query = EntityManager.createQuery("FROM Person person");
//list of person without the address list! But how???
List<Person> resultList = query.getResultList();
Thanks!

The only way I found is not returning the entity, returning only some fields of the entity. But I would like to find a solution that I can return the entity (in my example, the Person
entity).
I'm thinking if is possible to map the same table twice in Hibernate. In this way, I can mapping the same table without the EAGER associations. This will help me in a few cases...
