Java 无法根据路径解析属性[lieferungen]

我们在Maven测试中遇到了一个关键问题。 我们得到错误：无法根据路径解析属性[lieferungen]

不幸的是，其他帖子无法帮助我

这是我的堆栈跟踪：

这是我的域类Bestellung：

你还需要什么信息。我非常绝望。在这里坐了大约4天。

你介意给我们看一下你在

de.shop.bestellverwaltung.dao.BestellungDao.findBestellungenByIds（…）中的代码吗

？-我认为Hibernate查询有问题。您的数据库中有列

lieferungen

吗？-在

Bestellung

中，我们有一个字段

lieferung

（单数！）。。。

public class Bestellung implements java.io.Serializable {
    private static final long serialVersionUID = -2703770025221749393L;

    private static final String PREFIX = "Bestellung.";
    public static final String FIND_BESTELLUNGEN_BY_KUNDE = PREFIX + "findBestellungenByKunde";
    public static final String FIND_BESTELLUNG_BY_ID_FETCH_LIEFERUNG =
                               PREFIX + "findBestellungenByIdFetchLieferung";
    public static final String FIND_KUNDE_BY_ID = PREFIX + "findBestellungKundeById";

    public static final String PARAM_KUNDEID = "kundeId";
    public static final String PARAM_ID = "id";

    @Id
    @GeneratedValue
    @Column(name = "bid", unique = true, nullable = false, updatable = false, precision = LONG_ANZ_ZIFFERN)
    @Min(value = MIN_ID, message = "{bestellverwaltung.bestellung.id.min}", groups = IdGroup.class)
    private Long bid = KEINE_ID;



    @OneToMany(fetch = EAGER, cascade = { PERSIST, REMOVE })
    @JoinColumn(name = "bid_fk", nullable = false)
    private List<Bestellposition> bestellpositionen;

    @OneToMany(cascade = { PERSIST, REMOVE }, mappedBy = "bestellung")
    private List<Lieferung> lieferung;
