然后我评论了所有其他课程并一一开始，

这是创建的：

//
//  public void setReservations(List<Reservation> reservations) {

//  }
    
}

然后这个也是：

package br.com.negromonte.individualProject.model;

import java.util.List;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;

    }

    public String getName() {

    }

    public void setName(String name) {

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public double getRating() {

    public void setRating(double rating) {

}

但是这个：

package br.com.negromonte.individualProject.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity

    }

    public Prices(double weekday, double weekend, double weekdayFidelity, double weekendFidelity) {
        super();
        this.weekday = weekday;

    }

    public double getWeekday() {

    }

    public void setWeekday(double weekday) {
        this.weekday = weekday;
    }

    public double getWeekend() {
        return weekend;
    }

    public void setWeekend(double weekend) {
        this.weekend = weekend;
    }

    public double getWeekday_fidelity() {

    public void setWeekday_fidelity(double weekdayFidelity) {

要在创建上取得成功，我必须评论 Prices.java 和 Reservation.java，它们在未注释时不允许创建任何表，我的建模有问题吗？ 任何错误的注释？

需要像创建成功的表一样在id字段上加上@Id注解。
