我有下面的表实体，因为我试图更新一个现有的记录，这样做我会得到以下错误。我知道我在实体定义中犯了一些错误，但是我无法理解它。谢谢你的帮助。

**A

        -------------------
        |                 |
        B                 C
                      ---------
                      |       |
                      D       E**

@Entity
@Table()
public class A {
    @Id
    Long id;

    @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval=true)
    @JoinColumn(name = "id", referencedColumnName="id",  nullable = false)
    private Set<B> b;

    @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval=true)
    @JoinColumn(name = "id", referencedColumnName="ID",  nullable = false)  
    private Set<C> c;
}

@Entity
@Table()
public class B{
    @Id
    Long id;
}

@Entity
@Table()
public class C{
    @Id
    Long id;
    @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval=true)
    @JoinColumn(name = "id", referencedColumnName="id",  nullable = false)
    private Set<D> D;

    @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval=true)
    @JoinColumn(name = "id", referencedColumnName="ID",  nullable = false)  
    private Set<E> E;
}

@Entity
@Table()
public class D{
    @Id
    Long id;
}

@Entity
@Table()
public class E{
    @Id
    Long id;
}
