java - org.hibernate.AnnotationException : @OneToOne or @ManyToOne

Question

他似乎在通信代码中添加了@OneToMany和@ManyToOne，但由于某种原因，在启动Spring应用程序时出现错误.

类(class)客户:

import com.fasterxml.jackson.annotation.JsonManagedReference;
import lombok.Getter;
import lombok.Setter;

import javax.persistence.*;
import java.util.List;

@Getter
@Setter
@Entity
public class Customer extends User {

    public Customer(){ // Пустой конструктор для Hibernate

    }

    public Customer(String name, String lastName,
                    double wallet, List<Order> orderList){ // Пользовательский конструктор создается,
                                                            // когда нам нужно создать новый экземпляр,
                                                            // но у нас еще нет ID.
        super(name, lastName);
        this.wallet = wallet;
        this.orderList = orderList;
    }


    // Поля
    private @Id @GeneratedValue Long id;

    private double wallet;

    @OneToMany(mappedBy = "customer", fetch = FetchType.LAZY, cascade = CascadeType.ALL)

    // Методы
    public void depositMoney(){// Внести деньги на счет

        }

Answer 1

在类 Order 中导入 @entity from javax.persistence 而不是 org.hibernate.annotations.Entity
