hibernate注解配置一对多并且一方为联合主键

hibernate注解配置单向一对多（配置在一的一方）并且一的一方为联合主键，这个该怎么配置，最好是写一个demo

如下是一个“酒店房间信息表”，以hotelRoomId和hotelId为联合主键。其中配置了“一对多”和“多对一”

package cn.ssms.model;

import java.util.HashSet;
import java.util.Set;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@Entity
@Table(name="hotelRoom")
public class HotelRoom{
    private int hotelRoomId;            //客房编号
    private String hotelRoomName;       //房间名称
    private String hotelRoomImage;      //客房图片

    private Hotel hotel;                //属于哪个酒店

    private Set<HotelOrder> hotelOrderSet = new HashSet<HotelOrder>();              //相关的酒店订单的集合
    private Set<HotelRoomDate> hotelRoomDateSet = new HashSet<HotelRoomDate>();     //房间不同日期信息的集合

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="hotelRoomId")
    public int getHotelRoomId() {
        return hotelRoomId;
    }
    public void setHotelRoomId(int hotelRoomId) {
        this.hotelRoomId = hotelRoomId;
    }
    @Column(name="hotelRoomImage")
    public String getHotelRoomImage() {
        return hotelRoomImage;
    }
    public void setHotelRoomImage(String hotelRoomImage) {
        this.hotelRoomImage = hotelRoomImage;
    }
    @Column(name="hotelRoomName")
    public String getHotelRoomName() {
        return hotelRoomName;
    }
    public void setHotelRoomName(String hotelRoomName) {
        this.hotelRoomName = hotelRoomName;
    }

    @ManyToOne(fetch=FetchType.LAZY,targetEntity=Hotel.class)
    @JoinColumn(name="hotelId")
    public Hotel getHotel() {
        return hotel;
    }
    public void setHotel(Hotel hotel) {
        this.hotel = hotel;
    }
    @OneToMany(cascade=CascadeType.ALL,fetch=FetchType.LAZY,mappedBy="hotelRoom")
    public Set<HotelOrder> getHotelOrderSet() {
        return hotelOrderSet;
    }
    public void setHotelOrderSet(Set<HotelOrder> hotelOrderSet) {
        this.hotelOrderSet = hotelOrderSet;
    }
    @OneToMany(cascade=CascadeType.ALL,fetch=FetchType.LAZY,mappedBy="hotelRoom")
    public Set<HotelRoomDate> getHotelRoomDateSet() {
        return hotelRoomDateSet;
    }
    public void setHotelRoomDateSet(Set<HotelRoomDate> hotelRoomDateSet) {
        this.hotelRoomDateSet = hotelRoomDateSet;
    }
}

有疑问请回复。欢迎采纳，谢谢！

另一种情况
下面是“用户酒店收藏信息表”，以userId和hotelId为联合主键

package model;

import java.io.Serializable;

import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name="user_hotel_collect")
public class UserHotelCollect implements Serializable{
    private static final long serialVersionUID = 1L;
    private User user;              //是哪个用户收藏的
    private Hotel hotel;            //收藏的是哪个酒店

    @Id
    @ManyToOne(fetch=FetchType.LAZY,targetEntity=User.class)
    @JoinColumn(name="userId")
    public User getUser() {
        return user;
    }
    public void setUser(User user) {
        this.user = user;
    }

    @Id
    @ManyToOne(fetch=FetchType.LAZY,targetEntity=Hotel.class)
    @JoinColumn(name="hotelId")
    public Hotel getHotel() {
        return hotel;
    }
    public void setHotel(Hotel hotel) {
        this.hotel = hotel;
    }
}

按照你给我发的，我给你写的demo，你试下。大致就是这样，我之前写过这种

package model;

import java.util.HashSet;
import java.util.Set;

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

@Entity
@Table(name="user")
public class UserDemo {
    private String userName;            //用户名
    private String email;           //邮箱
    private Set<Card> cardSet = new HashSet<Card>();
    @Id
    @JoinColumn(name="userName")
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    @Id
    @JoinColumn(name="email")
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }

    @OneToMany(cascade=CascadeType.ALL,fetch=FetchType.LAZY)
    @JoinTable(name="name_address",
            joinColumns={@JoinColumn(name="username",referencedColumnName="userName")},
            inverseJoinColumns={@JoinColumn(name="email",referencedColumnName="email")})
    public Set<Card> getCardSet() {
        return cardSet;
    }
    public void setCardSet(Set<Card> cardSet) {
        this.cardSet = cardSet;
    }
}

你可以试试这两种，不知道有没有帮助到你
