我有一个基类person和3个继承自person的类。以下是一些简短的片段：

@Entity
public class Person extends Model{

    // ATTRIBUTES
    @Id
    @Column(columnDefinition = "integer")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    @Column(columnDefinition = "varchar(20) not null")
    protected String firstName;
    @Column(columnDefinition = "varchar(20) not null")
    protected String lastName;
    @Column(columnDefinition = "varchar(20) not null")
    protected String password;
    @Column(columnDefinition = "varchar(50) not null")
    protected String eMail;

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public class Boss extends Person {

    // ATTRIBUTES
    @Column(insertable = false, updatable = false)
    private String dtype;
    @OneToMany(mappedBy = "boss")
    private List<Employee> listEmployee;

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public class Employee extends Person {

    // ATTRIBUTES
    @Column(insertable = false, updatable = false)
    private String dtype;
    @Column(columnDefinition = "Varchar(20)")
    private String position;
    @ManyToOne
    private Boss boss;

现在我想存储一个员工，一个老板，然后再存储一个员工：

Employee e1 = new Employee(...);
Person p1 = new Person(e1);
Boss b = new Boss(...);
Person p2 = new Person(b);
Employee e2 = new Employee(...);
Person p3 = new Person(e2);
e1.save();
p1.save();
b.save();
p2.save();
e2.save();
p3.save();

这将在id为1和2的employee中生成2个条目，在id为1的boss中生成1个条目，在id为1、2和3的person中生成3个条目。e1的员工id为1，本人id为1，老板id为1，本人id为2，e2的员工id为2，本人id为3。
有没有可能在我的程序中不使用全局计数器而在employee和person中插入一个id相同的雇员？
谢谢您
