Ich habe diesen Fehler mit meinem Spring Data /JPA -Projekt: < /p>

Ich suche, aber ich finde kein Problem mit meiner Entität.@Entity
@NamedQuery(name="MYconnex.findAll", query="SELECT u FROM MYconnex u")
public class MYconnex implements Serializable {
private static final long serialVersionUID = 1L;

@Id
private long IDCON;

private String key;

private Timestamp dateconnex;

private String mel;

private int tel;

//bi-directional many-to-one association to MYdonnees
@OneToMany(mappedBy="MYconnex")
private List MYdonnees;

//Getter and setter
}
< /code>

mydonnees: < /p>

@Entity
@NamedQuery(name="MYdonnees.findAll", query="SELECT u FROM MYdonnees u")
@Table(name="MYdonnees")
public class MYdonnees implements Serializable {
private static final long serialVersionUID = 1L;

@Id
private long idata;

@Lob
@Column(name="\"DATA\"")
private String data;

//bi-directional many-to-one association to MYconnex
@ManyToOne
private MYconnex MYconnex;

public MYdonnees() {
}

//Getter and Setter

}
< /code>

Mein crudrepository: < /p>

public interface ADRESSRepository extends CrudRepository {
}
< /code>

Die Datenbank: < /p>

< /p>

Ich denke, das Problem.>
