我希望@ElementCollection中有重复

Question

Hy，我使用@Repositor CrudRepository<Player, String>

存储一些玩家信息。

每位玩家都有多张牌，有时会不止一次。

我如何在播放机中允许它？每次我尝试多次插入一次时都会出错

我的代码

public class Player {

    @Id
    String playerId;

    @ElementCollection(targetClass = Card.class)
    @LazyCollection(LazyCollectionOption.FALSE)
    Collection<Card> cards = new ArrayList<>();

}

public enum Card {
    km25, km50, km75, km100, km200, crevaison, roueDeSecours, increvable, accident, garage, asDuVolant, feuRouge, feuVert, vehiculePrioritaire, panneDessence, stationService, citerne, limiteVitesse, finLimiteVitesse
;
