我有以下实体：

@Entity
@Table(name="NOTE")
public class Note implements Serializable {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long id;

    @Column(name="DATE")
    private Calendar date;

    @Column(name="TOTAL")
    private double total;

    @ManyToOne
    private Collaborateur collaborateur;

    @OneToMany(cascade=CascadeType.ALL)
    private List<Frais> listfrais = new ArrayList<Frais>();

    // getters and setters
}


@Entity
@Table(name = "COLLABORATEUR")
// @IdClass(PersonnePK.class)
public class Collaborateur implements Serializable {
    @Id
    @Column(name="ID_COLLABORATEUR")
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int idc;
    private String nom;
    private String prenom;
    @OneToMany(mappedBy="collaborateur",cascade =CascadeType.ALL)
    private List<Note> notes= new ArrayList<Note>();

    // getters and setters
 }


@Entity
@Table(name="FRAIS")
public class Frais implements Serializable{
    @Id
    @Column(name="ID_FRAIS")
    private long idf;

    @Column(name="DESIGNATION")
    private String designation;

    @Column(name="MONTANT")
    private double motant;

    @Column(name="JUSTIFICATIF")
    @Lob
    @Basic(fetch=FetchType.LAZY)
    private Byte justificatif;

    //private Projet projet;
    //  private Note note;

    // getters and setters

}

错误是：

答案 0 :(得分：0)

在collaborateur上缺少级联首选项。你的代码中有这个。

@ManyToOne(cascade =CascadeType.ALL)
private Collaborateur collaborateur;

在那里添加级联类型。
