Я пытаюсь сделать OneToMany сопоставление с Person и CreditCard Class, One Person может иметь несколько Credit карты . Это мой личный класс 

package com.example.model;

import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@Entity
@Table(name = "PERSON")
public class Person {

     @Id
     @GeneratedValue(strategy= GenerationType.IDENTITY)
     private Integer id;

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

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

     @Column(name = "money")
     private Double money;

     @OneToMany(mappedBy="person",cascade=CascadeType.ALL)
     private Set<CreditCard> creditCard;



}

Это мой класс кредитной карты, в этом я использую ассоциацию, я хочу добавить данные с jsp страниц для этого мне нужно Person Class объект в CreditCard также класс, и я хочу заполнить это приложение, используя Только две таблицы . 

package com.example.model;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;

public class CreditCard {

     @Id
     @GeneratedValue(strategy= GenerationType.IDENTITY)
     private Integer id;

     @Column(name = "type")
     private String type;

     @Column(name = "number")
     private String number;

     @ManyToOne(cascade = CascadeType.ALL)
     @JoinColumn(name="person_id", nullable=false)
     private Person person;

}

Application.properties Файл

Когда я запускаю приложение, оно выдает сообщение об ошибке «Вот так:

Похоже, вы CreditCard класс не имеет @Entity аннотации. Попробуйте добавить это там тоже.

Вы пропустите @Entity Аннотация на CreditCard

@Entity
public class CreditCard {
