我想爲較大的實體嵌入一個較小的類作爲字段，並且這是我在過去玩過的東西！ 2.1但現在Ebean在模式創建期間給我一個錯誤。爲什麼Playframework會告訴我它不支持子類化？
這裏是我的課（非常簡單沒有任何幻想）：
@Embeddable
public class Pricing implements Serializable {
private Long value;
private String currency;
//getters and setters
}
，我試圖把它嵌入到這樣的：
@Entity
public class MyEntity extends Model {
@Id
@GeneratedValue
private Long id;
@Embedded
private Pricing priceProposed;
//getters and setters
}
我想實現的是，看起來表像這樣的東西
----------------------------------------------------
| id | priceProposed.value | priceProposed.currency|
----------------------------------------------------
| 1 | 200 | USD |
| 2 | 1200000 | JPY |
----------------------------------------------------
就像你看到我沒有嘗試任何困難。但是我收到以下錯誤，提到不再支持子類化。但我不認爲這符合subClassing的資格，還是我完全錯了？

有人能告訴我發生了什麼事嗎？這與什麼有關？是否有人看到我犯的錯誤（自從我上一次Ebean + Play！項目已經過去了一年，所以我可能會忘記一些非常愚蠢的東西）？
