当我想要与 tabble 建立 OneToOne 关系时：NewUser 到 CreateBill 我遇到异常： Exception in thread "main" org.hibernate.AnnotationException: Unknown mappedBy in: domain.CreateBill.user, referenced property unknown: domain.NewUser.user

在开关中，无论我点击“E”还是“N”，我都会遇到这个异常......

第一类与NewUser，主要是get/set

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToOne;
import javax.persistence.Table;

@Entity
@Table(name="Urzytkownik")
public class NewUser {

    @Id
    @GeneratedValue
    private long id;

    private String name;
    private String surName;
    private int pesel; // s08
    private int telephoneNumber;
    private int pin;

    @OneToOne
    private CreateBill bill;


    public int getPin() {
        return pin;
    }

    public void setPin(int pin) {
        this.pin = pin; …

我想在按下“注册”按钮后从主页index.html（用户）重定向到他能够创建帐户的页面。然而，什么也没有发生。仅添加到地址：http://localhost:8080/DrinkShop注释在 /register 末尾
