Spring JPA抽象类行为

Question

我有疑问，我做错了什么，我的实体显示不像我想要的，当我去h2-console我可以看到3张桌子，当我去persons桌子时employee manager persons我看到所有延伸这个abstract的人上课（employee，manager），但是当我去其他桌子时，我只能看到这类课程的id。我的问题是如何修复它，以及如何使每个表显示从1盯着的id，因为现在employee表有3个id 1,2,3，而manager表有4,5，person表格显示正确。我想在employee表中显示3个雇员，在managers表中显示2个经理，在people表中显示每个实体，并且每个表中的ID都显示为1。

抽象类人

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "descriminatorColumn")
@Table(name = "persons")
public abstract class Person {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;

@Column(name = "first_name")
private String firstName;

@Column(name = "last_name")
private String lastName;

@Column(name = "email")
private String address;

@Column(name = "age")
private int age;

public Person(String firstName, String lastName, String address, int age) {
    this.firstName = firstName;
    this.lastName = lastName;
    this.address = address;
    this.age = age;
}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}

public int getAge() {
    return age;
}

public void setAge(int age) {
    this.age = age;
}

@Override
public String toString() {
    return "Person{" +
            "firstName='" + firstName + '\'' +
            ", lastName='" + lastName + '\'' +
            ", address='" + address + '\'' +
            ", age=" + age +
            '}';
  }
}

Manager类扩展了Person抽象类

@Entity
@Table(name = "managers")
public class Manager extends Person {

public Manager(String firstName, String lastName, String email, int age) {
    super(firstName, lastName, email, age);
}

@Override
public String toString() {
    return super.toString();
 }
}

Employee类扩展了Person抽象类

@Entity
@Table(name = "employees")
public class Employee extends Person {

public Employee(String firstName, String lastName, String address, int age) {
    super(firstName, lastName, address, age);
}

@Override
public String toString() {
    return super.toString();
  }
}
