原因：org.hibernate.AnnotationException：在不同包中的实体上使用两次相同的实体名称，但是名称相同

Question

I have two Entities with the same name, but in different package. For me it is obvious that should work. There is no duplicated name for entities.

But I am getting an error:

Caused by: org.hibernate.AnnotationException: Use of the same entity name twice: Variant

I found solution, that tells me to use string value as Parameter for name attribute of @Entity annotation, fe:

@Entity(name="legal_Variant")

But I don't like to use Strings in code. Can it be done other way? Fe using java reflection, or configuring somehow JPA to use whole name (with package name)?

For me it is quite strange. I thought that JPA takes care of package name also.

My classes code:

package insurance.models.liability.hiv;
@Entity
@Table(name="lLiability_Part_Hiv_Var")
public class Variant extends GenericDictionary<Variant> {
}

package insurance.models.liability.legal;
@Entity
@Table(name="liability_Part_Legal_Var")
public class Variant extends GenericDictionary<Variant> {}

Answer 1

It can be done in the mapping file:

<hibernate-mapping>
    <import class="insurance.models.liability.legal.Variant" rename="Var1" />
</hibernate-mapping>

You can now use an HQL query such as

from Var1
