插入新数据时出现javax.persistence.EntityNotFoundException

Question

构建一个处理足球等惩罚的应用程序。比如训练太晚了等等。

首先：它是一个带有 Vaadin 前端的 Spring Boot 应用程序和带有 Spring Data JPA 的 H2 数据库

问题在于向 H2 数据库添加新实体。插入玩家和惩罚本身没有问题，但是当我尝试将这些 Id 与另一个表（PunishmentToPlayer）映射时，它给了我一个 EntityNotFoundException。

数据库中的玩家和惩罚实体也是正确的。

实体播放器

@Setter
@Getter
@Entity
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Player extends AbstractEntity{

    private String firstName;
    private String lastName;
}

实体惩罚

@Setter
@Getter
@Entity
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Punishment extends AbstractEntity{

    private String description;
    private Double amount;
}

对玩家的实体惩罚

@Setter
@Getter
@Entity
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class PunishmentToPlayer extends AbstractEntity{

    @OneToOne
    private Player player;

    @OneToOne
    private Punishment punishment;
}

尝试在此处添加我的示例数据

@Component
public class DataHelper {

    public void addPlayer(PlayerService playerService){
        playerService.saveOrUpdate(buildPlayer("Player1_Name", "Player1_Lastname"));
        playerService.saveOrUpdate(buildPlayer("Player2_Name", "Player2_Lastname"));
        playerService.saveOrUpdate(buildPlayer("Player3_Name", "Player3_Lastname"));
        playerService.saveOrUpdate(buildPlayer("Player4_Name", "Player4_Lastname"));
    }

    public void addPunishments(PunishmentService punishmentService){
        punishmentService.saveOrUpdate(buildPunishment("Description 1", 20.00));
        punishmentService.saveOrUpdate(buildPunishment("Description 2", 15.00));
        punishmentService.saveOrUpdate(buildPunishment("Description 3", 10.00));
        punishmentService.saveOrUpdate(buildPunishment("Description 4", 5.00));
    }

    public void addConnections(PunishmentToPlayerService punishmentToPlayerService, PlayerService playerService, PunishmentService punishmentService){
        List<Player> players =  playerService.getAllPlayer();
        List<Punishment> punishments = punishmentService.getAllPunishments();

        punishmentToPlayerService.saveOrUpdate(buildPunishmentToPlayer(players.get(0), punishments.get(0)));
        punishmentToPlayerService.saveOrUpdate(buildPunishmentToPlayer(players.get(0), punishments.get(2)));
        punishmentToPlayerService.saveOrUpdate(buildPunishmentToPlayer(players.get(1), punishments.get(1)));
        punishmentToPlayerService.saveOrUpdate(buildPunishmentToPlayer(players.get(2), punishments.get(0)));
        punishmentToPlayerService.saveOrUpdate(buildPunishmentToPlayer(players.get(2), punishments.get(3)));
        punishmentToPlayerService.saveOrUpdate(buildPunishmentToPlayer(players.get(3), punishments.get(0)));
        punishmentToPlayerService.saveOrUpdate(buildPunishmentToPlayer(players.get(3), punishments.get(3)));
        punishmentToPlayerService.saveOrUpdate(buildPunishmentToPlayer(players.get(3), punishments.get(3)));
    }

    private Player buildPlayer(String firstname, String lastname){
        return Player.builder()
                .firstName(firstname)
                .lastName(lastname)
                .build();
    }

    private Punishment buildPunishment(String description, double value){
        return Punishment.builder()
                .description(description)
                .amount(value)
                .build();
    }

    private PunishmentToPlayer buildPunishmentToPlayer(Player player, Punishment punishment){
        return PunishmentToPlayer.builder()
                .player(player)
                .punishment(punishment)
                .build();
    }
}

调试时，它向我显示单个 PunishmentToPlayerObjects 中的所有正确数据

在 DataHelper 的 saveOrUpdate 方法中，PunishmentToPlayerService 调用方法：

public void saveOrUpdate(PunishmentToPlayer punishmentToPlayer){
        punishmentToPlayerRepository.save(punishmentToPlayer);
}

仅指 Spring Data 中 CrudRepository 的标准

save

方法

这里是堆栈跟踪：

并没有真正尝试任何特别的事情，因为它应该有效。

Answer 1

尝试为

player

类中的

punishment

和

PunishmentToPlayer

字段添加级联类型

public class PunishmentToPlayer extends AbstractEntity{

  @OneToOne(cascade = CascadeType.ALL)
  private Player player;

  @OneToOne(cascade = CascadeType.ALL)
  private Punishment punishment;
}
