Hibernate 5.2.12.Final
我想用CriteriaBuilder构建器替换depreacted session.createCriteria(请参阅org.hibernate.Criteria),我有以下异常
无法在此处找到具有给定名称[filtre]的Attribute ManagedType [com ... DonneeReference]
on:
criteria.where(builder.equal(root.get(" filtre"),filtre));
@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);
}
}
似乎CriteriaBuilder仅适用于实体,而不适用于旧的hbm映射文件。

答案 0 :(得分:0)
我遇到了相同的错误,该错误通过将组合键定义为实现Serializable
并具有正确的equals
和hashCode
的单独的Java类而解决。
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>
}
hbm文件应相应为
<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>
