假設你有這樣映射的@Embeddable
:如何處理@Type上@AttributeOverrides
@Embeddable
public class Wheel {
@Column(name = "COLOR")
@Type(type = "my.package.ColorUserType")
private Color theColor;
}
,並嘗試使用這樣的:
@Entity
@Table(name = "CAR")
public class Car {
@Embedded
@AttributeOverride(
column = @Column(name = "STEERING_WHEEL_COLOR")
name = "theColor"
)
private Wheel steeringWheel;
}
當我這樣做,我在啓動時會得到一個大胖子org.hibernate.MappingException: Could not determine type for: my.package.Color
。
那麼有沒有辦法來覆蓋類型或確保它使用@Embeddable
中定義的類型,因爲當使用@AttributeOverride
時顯然不會保留它?
