I have this error :

any idea what is the problem ?

[A. Aka]

I know the problem but I do not know how to solve it :

employe in my json should be employeID,

and I have this on my entity :

@Entity
@JsonIdentityInfo(generator=ObjectIdGenerators.PropertyGenerator.class, property="employeID", scope = Employe.class)
public class Employe implements Serializable {
	
	private static final long serialVersionUID = 1L;
	
	@Id
	@GeneratedValue(strategy=GenerationType.AUTO)
	private int employeID;

	private int actif;

but I have also this :

@Entity
@JsonIdentityInfo(generator=ObjectIdGenerators.PropertyGenerator.class, property="numConvocation", scope = Controle.class)
public class Controle implements Serializable {
	private static final long serialVersionUID = 1L;

	@Id	
	private int numConvocation;

	private int assurance;

	private int conformite;

	private int convocation;

	private Date dateControle;

	private int montant;

	private int paye;

	private String resultatFinal;

	private int scoreFinal;

	private int surtaxe;
	
	@ManyToOne
	@JoinColumn(name="ligneID")
	private Ligne ligne;
	
	@OneToOne(cascade= CascadeType.ALL)
	@JoinColumn(name="numConvocation")
	private Convocation convocationBean;

	@ManyToOne
	@JoinColumn(name="employeID")
	private Employe employe;

	@ManyToOne
	@JoinColumn(name="statutControleID")
	private StatutControle statutControle;

	
	@OneToMany(fetch = FetchType.LAZY, mappedBy="controle")
	private List<Test> tests;
	
	public Controle() {
	}

[A. Aka]

the problem is

"employe": 1

while this should be :

"employe": {
                                "employeID": 1,
                                "actif": 1,
                                "login": "toto",
                                "nom": "Dupont",
                                "password": "d74ff0ee8da3b9806b18c877dbf29bbde50b5bd8e4dad7a3a725000feb82e8f1",
                                "prenom": "Thomas",
                                "controles": [
                                    1234
                                ],
                                "type": "1"}

any idea on how to solve it ?
