我正在为我的存储库编写测试，我想用一些数据预填充我的测试 H2 数据库。

<dataset>
    <car
            id = "carId"
            name = "some name"
    />

    <user
            id = "userId"
            first_name = "Firstname 1"
            car_id = "carId"
            created_date = "2020-06-23 10:00:00.000"
            last_modified_date = "2020-06-23 10:00:00.000"
    />

</dataset>


@Entity(name = "user")
public class UserEntity extends BaseEntity {
    @Id
    @GeneratedValue(generator="system-uuid")
    @GenericGenerator(name="system-uuid", strategy = "uuid")
    @Column(updatable = false, nullable = false)
    private String id;
    @Column(nullable = false)
    private String firstName;
    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "car_id", referencedColumnName = "id")
    private CarEntity car;
}

@Entity(name = "car")
public class CarEntity extends BaseEntity {
    @Id
    @GeneratedValue(generator="system-uuid")
    @GenericGenerator(name="system-uuid", strategy = "uuid")
    @Column(updatable = false, nullable = false)
    private String id;
    private String name;
    @OneToOne(mappedBy = "car")
    private UserEntity userEntity;
}

所以汽车和用户是一对一的关系。

当我运行这个我得到这个错误：
