道

@Override
public Compte findComptePer(String user, String pwd, Integer id) {
    String req="select com from Compte  com where com.statuts='actif' and  com.user='"+user+"' and com.pwd='"+pwd+"' "
            + "and com.personnels.id in (select p.id from Personnels p where statuts='actif')";
    return  (Compte) sessionfactory.getCurrentSession().createQuery(req).uniqueResult();

}

实体

enter code  @Entity
public class Personnels implements Serializable {
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
@ManyToOne
@JoinColumn(name = "id_agence", referencedColumnName = "id")
private Agence agence;
private String nom;
private String prenom;
private String tel;
private String adresse;
private String statuts



@Entity
public class Compte implements Serializable{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
@ManyToOne
@JoinColumn(name = "idPersonnel")
private Personnels personnels;
private String user;
private String pwd;
private String statuts;
@Temporal(TemporalType.DATE)
private Date date;
@ManyToOne
@JoinColumn(name = "id_roles")
private Roles roles;

Answer 1

HQL中别名com的问题。 com.company.location.entities.Compte对此别名的含义不正确。

select com from Compte com where com.statuts='actif' and com.user='"+user+"' and com.pwd='"+pwd+"' " + "and com.personnels.id in (select p.id from Personnels p where statuts='actif'

只需将其更改为compte

即可

select compte from Compte compte where compte.statuts='actif' ...

并且，请使用命名查询参数
