When using inheritance for EmbeddedId classes, Hibernate generates meta model classes as follows:
{code}
package com.setech.mrovelocityhub.persistence.maintenance.model;
import javax.annotation.Generated;
import javax.persistence.metamodel.SingularAttribute;
import javax.persistence.metamodel.StaticMetamodel;
@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(WorkOrderId.class)
public abstract class WorkOrderId_ {
public static volatile SingularAttribute<WorkOrderId, Long> plantId;
public static volatile SingularAttribute<WorkOrderId, String> workOrder;
}
{code}
{code}
package com.setech.mrovelocityhub.persistence.maintenance.model;
import javax.annotation.Generated;
import javax.persistence.metamodel.SingularAttribute;
import javax.persistence.metamodel.StaticMetamodel;
@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(WorkOrderComponentId.class)
public abstract class WorkOrderComponentId_ extends com.setech.mrovelocityhub.persistence.maintenance.model.WorkOrderId_ {
public static volatile SingularAttribute<WorkOrderComponentId, Long> lineNumber;
}
{code}
The associated source java classes being used to generate the model are as follows:
{code}
@Embeddable
@MappedSuperclass
public class WorkOrderId implements Serializable {
private String workOrder;
private Long plantId;
/* other stuffs */
}
@Embeddable
public class WorkOrderComponentId extends WorkOrderId {
private Long lineNumber;
/* other stuffs */
}
{code}
The WorkOrder and WorkOrderComponent classes both reference their Id classes using @EmbeddedId annotation on the respective classes.
But during startup it writes the following to the log file:
{ quote noformat }
2013-11-05 08:40:50,028 ERROR [org.hibernate.ejb.metamodel.MetadataContext]: HHH015011: Unable to locate static metamodel field : com.setech.mrovelocityhub.persistence.maintenance.model.WorkOrderComponentId_#plantId
