hibernate - JPA MappedSuperClass -

-

i using @mappedsuperclass in hibernate project:

@mappedsuperclass public abstract class abstracthotel extends abstractdata {     protected string id;     protected string name;     protected string type;     .... }  @entity @table(name = "t_hotel") public class hotel extends abstracthotel {     @attributeoverride(name = "id", column = @column(name = "hotel_id"))     protected string id;      @attributeoverride(name = "name", column = @column(name = "hotel_name"))     protected string name;      @attributeoverride(name = "type", column = @column(name = "hotel_type"))     protected string type;      ... }

as shown, want column can overrideed in subclass, error:

org.hibernate.mappingexception: duplicate property mapping of id found in cn.test.hotel

is possible fix this?
