Java - JPA : ManyToOne join table not updated
0
I want to make a join table from the table Projets(idprojets PK,contrats) with Contracts(idcontrats PK, contrat_name). The final table would be JoinProjetsContrats(idprojet,idcontrat)
Here's my code so far:
Projet
@Entity
@Table(name="projets")
public class Projet implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@SequenceGenerator(name="PROJETS_IDPROJET_GENERATOR", sequenceName="PROJETS_IDPROJET_SEQ",allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="PROJETS_IDPROJET_GENERATOR")
private Integer idprojet;
@Column(name="charge_totale")
private double chargeTotale;
private String intitule;
private String statut;
//bi-directional many-to-one association to Contrat
@ManyToOne
@JoinColumn(name="idcontrat")
private Contrat contrat;
Contrat:
@Entity
@Table(name="contrats")
public class Contrat implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@SequenceGenerator(name="CONTRATS_IDCONTRAT_GENERATOR", sequenceName="CONTRATS_IDCONTRAT_SEQ",allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="CONTRATS_IDCONTRAT_GENERATOR")
private Integer idcontrat;
private String nom;
//uni-directional many-to-many association to Projet
@ManyToMany
@JoinTable(
name=""joinProjetsContrats""
, joinColumns={
@JoinColumn(name="idcontrats")
}
, inverseJoinColumns={
@JoinColumn(name="idprojets")
}
)
private Set<Projet> projets1;
//bi-directional many-to-one association to Projet
@OneToMany(mappedBy="contrat")
private Set<Projet> projets2;
I guess there's something missing here, since the update is not made in my SQL table when I create a "projet". Projet table is updated.
Any ideas of the mistake I've missed?
Thanks!

So why is there a@ManyToOne? Your question is not realy clear - or your setup

I don't know what I have to change then, changing ManyToMany to OneToMany doesn't do anything

Please show both parts of both entities. So I want to see theContractside, too
