Question

Say you have an @Embeddable mapped like this:

@Embeddable
public class Wheel {
  @Column(name = "COLOR")
  @Type(type = "my.package.ColorUserType")
  private Color theColor;
}

and you try to use it like this:

@Entity
@Table(name = "CAR")
public class Car {
  @Embedded
  @AttributeOverride(
    column = @Column(name = "STEERING_WHEEL_COLOR")
    name = "theColor"
  )
  private Wheel steeringWheel;
}

When I do this, I get a big, fat org.hibernate.MappingException: Could not determine type for: my.package.Color on startup.

So is there a way to override the type or make sure it uses the defined type in the @Embeddable since it’s obviously not being kept when the @AttributeOverride is used?

Answer 1

It looks like this can’t be done because it’s not a Basic type mapping. Source: Java 6 API – AttributeOverride.
