在此ManagedType上找不到具有给定名称的属性

Question

冬眠5.2.12.1决赛

我想用CriteriaBuilder替换depreracted session.createCriteria（参见org.hibernate.Criteria），我有以下异常

在此ManagedType[com…DonneReference]上找不到具有给定名称[filtre]的属性

上：

其中（builder.equal（root.get（“filter”），filter））；

@Repository
    public class ReferenceDaoImpl implements ReferenceDao {

        @Autowired
        private SessionFactory sessionFactory;

        ...
        private static final String REQUEST_ALL_VERSIONS = "select  tableref  from " + DonneeReference.class.getName() + " tableref "
            + "where tableref.table = ? and tableref.dateAnnulation = null";

        private static final String REQUETE_RECHERCHE_LOCALITE = "select loc from " + Localite.class.getName() + " loc "
            + "where loc.codeInsee = ? AND loc.codePostal = ? ";

        private static final String REQUETE_RECHERCHE_LOCALITES_COMMUNE = "select loc from " + Localite.class.getName() + " loc where loc.codeInsee = ?";

        ...
        // Constructeurs
        public ReferenceDaoImpl() {
        }


        @Override
        public DonneeReference rechercherDonneeUnique(String identab, String critere, String filtre, Date dateEffet) {
            DonneeReference donneeReference = null;
            Session session = sessionFactory.getCurrentSession();

            // Sample try
            CriteriaBuilder builder = sessionFactory.getCriteriaBuilder();
            CriteriaQuery<DonneeReference> criteria = builder.createQuery(DonneeReference.class);
            Root<DonneeReference> root = criteria.from(DonneeReference.class);
            criteria.select(root);
            criteria.where(builder.equal(root.get("filtre"), filtre));
            List<DonneeReference> results = session.createQuery(criteria).getResultList();
            return results.get(0);
        }
    }

CriteriaBuilder似乎只适用于实体，而不适用于旧的hbm映射文件。

                        and tab.filtre = referenceData.filtre
                        and referenceData.dateEffet <= :date
                    )
                and referenceData.dateAnnulation is null

我遇到了同样的错误，通过将复合键定义为一个独立的java类来解决这个问题，该类实现了Serializable，并且具有正确的等于

public class DonneeReference {
    private DonneeReferenceId donneeReferenceId;  // <-- composite key goes here
    private String zone3;
    private String libelle;
    <other fields here>

    <getter & setter for all the fields>
}

public DonneeReferenceId implements Serializable {
    private String table;
    private String code;
    private String filtre;
    private String version;

    <getter & setter for all the fields>

    <equals & hashCode involving all fields here>
}

并且hbm文件应该相应地

<class name="DonneeReference" table="REF_REFPARAM">
    <composite-id name="donneeReferenceId" class="DonneeReferenceId">
        <key-property name="table" column="CT0_IDENTAB"/>
        <key-property name="code" column="CT0_CRIT1"/>
        <key-property name="filtre" column="CT0_CRIT2"/>
        <key-property name="version" column="CT0_NOVERS"/>
    </composite-id>

    <property name="zone3" column="CT0_ZONX3"/>
    <property name="libelle" column="CT0_ZONX2"/>
    ...
</class>
