我最近创建了一个车辆管理系统，这个系统是从mysql数据库和服务器端派生的，在spring中我想创建另一个表（在运行时自动），它只显示现有表中的两列。
问题是我做错了什么？最终目标-当添加/删除/编辑车辆时，两个表将同步工作，并且不会发生碰撞我将很高兴得到您的帮助
下面是“汽车”类

import javax.persistence.*;
import java.time.LocalDate;

@Entity
@Table(name = "car")
public class Car {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long carId;

    private String licensePlate;

    private int carType;

    private boolean suv;

    private int engineCapacity;

    private int year;

    private String note;

    private int status;

    private LocalDate careDate;

    private LocalDate editDate;

    public Car() {
    }

    public Car(long carId) {
        this.carId = carId;
    }

    public long getCarId() {
        return carId;
    }

    public void setCarId(long carId) {
        this.carId = carId;
    }

    public String getLicensePlate() {
        return licensePlate;
    }

    public void setLicensePlate(String licensePlate) {
        this.licensePlate = licensePlate;
    }

    public int getCarType() {
        return carType;
    }

    public void setCarType(int carType) {
        this.carType = carType;
    }

    public boolean isSuv() {
        return suv;
    }

    public void setSuv(boolean SUV) {
        this.suv = SUV;
    }

    public int getEngineCapacity() {
        return engineCapacity;
    }

    public void setEngineCapacity(int engineCapacity) {
        this.engineCapacity = engineCapacity;
    }

    public int getYear() {
        return year;
    }

    public void setYear(int year) {
        this.year = year;
    }

    public String getNote() {
        return note;
    }

    public void setNote(String note) {
        this.note = note;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public LocalDate getCareDate() {
        return careDate;
    }

    public void setCareDate(LocalDate careDate) {
        this.careDate = careDate;
    }

    public LocalDate getEditDate() {
        return editDate;
    }

    public void setEditDate(LocalDate editDate) {
        this.editDate = editDate;
    }
}

cartype类只需要创建另一个mysql表和相关列（car\u id和car\u type）

package com.example.CarSystemMatanElbaz.model;

import javax.persistence.*;
import java.util.ArrayList;
import java.util.HashSet;
import java.util.List;
import java.util.Set;

@Entity
public class CarType {

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

    @OneToOne(cascade = CascadeType.ALL,fetch = FetchType.LAZY,orphanRemoval = true)
    @JoinColumn(name= "car_id")
    private Car carId;

    @OneToOne(cascade = CascadeType.ALL,fetch = FetchType.LAZY,orphanRemoval = true)
    @JoinColumn(name= "car_type")
    private Car carType;

    public CarType() {

    }

    public CarType(long id, Car carId, Car carType) {
        this.id = id;
        this.carId = carId;
        this.carType = carType;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public Car getCarId() {
        return carId;
    }

    public void setCarId(Car carId) {
        this.carId = carId;
    }

    public Car getCarType() {
        return carType;
    }

    public void setCarType(Car carType) {
        this.carType = carType;
    }
}
