java - Kundera は、クエリで文字列 "1" を整数 1 にキャストします

Question

次の例外があります：

Caused by: com.impetus.kundera.KunderaException: com.datastax.driver.core.exceptions.InvalidQueryException: Invalid INTEGER constant (1) for promo_code_id of type ascii

次のコード ブロックの実行中:

public List<ActivatedPromoCode> findRegistrationPromoBetween(List<String> promoCodeIds, Date startDate, Date endDate)
            throws DAOException {
        try {
            if (promoCodeIds == null ) return null;

            TypedQuery<ActivatedPromoCode> query = getEM().createQuery(
                    "select apc from ActivatedPromoCode apc where apc.promoCodeId in ?1 " +
                            "and apc.isRegistrationPromo = true " +
                            "and apc.activationTimestamp > ?2 and apc.activationTimestamp < ?3",
                    ActivatedPromoCode.class);
            query.setParameter(1, promoCodeIds);
            query.setParameter(2, startDate);
            query.setParameter(3, endDate);

            try {
                return query.getResultList();
            } catch (NoResultException e) {
                return null;
            }
        } catch (Exception e) {
            throw new DAOException("Search activated promo codes activated during registration", e);
        }

ログに、Kundera が Cassandra に送信するクエリを示す次のレコードが表示されます。

クラス宣言:

    @Id
    @GeneratedValue
    @Column(name = "id", nullable = false, unique = true)
    private String id;

    @Column(name = "promo_code_id")
    private String promoCodeId;

    @Column(name = "code")

Kundera が String "1" を Integer 1 に変換する理由を誰か説明できますか? どうすればそれを回避できますか？

ありがとう
