Java Spring查詢

Question

我想做一個查詢購買我沒有訪問到h2數據庫模式，所以我不知道如何命名連接屬性。 我基本上想要在特定的日期間隔內查詢酒店中的可用房間。對於我需要一個這樣的查詢：

Select Room 
    From Room Inner Join Booking On Room.Id = Booking.RoomId Inner Join RoomType On RoomType.Id = Room.RoomTypeId 
    Where NOT ((Booking.beginDate >= @initDate And Booking.beginDate <= @endtDate) or (Booking.beginDate >= @initDate And Booking.endDate <= @endDate) 
or (Booking.beginDate <= @initDate and Booking.endDate >= @endDate)) and Booking.Approved = 1 and RoomType.Id = @roomType) 

在java中春：

@Query(........) 
Iterable<Room> findAvaiableRooms(Date initDate, Date endDate, long roomType); 

######## The Entities ####### 

@Entity 
public class Booking { 
    @Id 
    @GeneratedValue(strategy=GenerationType.AUTO) 
    private long id; 
    private Date beginDate; 
    private Date endDate; 
    private boolean aproved; 

    @ManyToOne 
    private Room room; 
} 



@Entity 
    public class Room { 
     @Id 
     @GeneratedValue(strategy = GenerationType.AUTO) 
     private long id; 
     private String name; 

     @ManyToOne 
     private RoomType roomType; 

     @OneToMany(fetch = FetchType.LAZY, cascade=CascadeType.ALL, mappedBy="room", orphanRemoval = true) 
     private Collection<Booking> bookings = new ArrayList<Booking>(); 
    } 

@Entity 
public class RoomType { 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private long id; 
    private String type; 
    private int price; 
    private int numberOfRooms; 

    @OneToMany(fetch = FetchType.LAZY, cascade=CascadeType.ALL, mappedBy="roomType", orphanRemoval = true) 
    private Collection<Room> rooms = new ArrayList<Room>(); 
} 

我真的不知道該如何查詢應爲與數據庫一致。
