从引用具有由JPA带注释的实体类创建的表的其他表的表中删除行

Question

我已经从JPA带注释的实体类生成了我的数据库表，如下所示：

@Entity
@Table (name="chauffeur")
public class Chauffeur{    

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "MYNOTIFSEQ") //identificateur de de la séquence
    @SequenceGenerator(name = "MYNOTIFSEQ", sequenceName = "MY_SEQ") //nom de la séquence dans la base
    private Long id; // Identifiant formation (Clé primaire)
    private String nom;
    private String prenom;
    private String adresse;
    private String telephone;
    private String login;
    private String motdepasse;
    private String position;
    private String disponible;

    @OneToOne(mappedBy = "c")
    private Taxi t;

    @OneToOne(mappedBy = "chau")
    private  Favoris favoris;

和这堂课：

@Entity
@Table(name = "favoris")
public class Favoris {
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "MYNOTIFSEQ")
    @SequenceGenerator(name = "MYNOTIFSEQ", sequenceName = "MY_SEQ")
    private Long id; // Identifiant formation (Clé primaire)

    @OneToOne(cascade={CascadeType.PERSIST, CascadeType.REMOVE},orphanRemoval=true)
    private Taxi taxi;

    @OneToOne(cascade={CascadeType.PERSIST, CascadeType.REMOVE},orphanRemoval=true)
    private Chauffeur chau;

我的问题是我想从Chauffeur表中删除一行，但是这个表引用了Favoris表 这就是我有这个错误的原因：

java.sql.SQLIntegrityConstraintViolationException: ORA-02292: integrity constraint (MYBASE.FK_SUIDVMBNQQO4MUFI27VCLVPMV) violated - child record found

这是我使用的查询：

delete from Chauffeur where id ='1'

我该如何解决问题，谢谢
