Как вставить дату в базу данных с помощью Spring mvc?

Question

Я получаю исключение исключающего указателя, в то время как я пытаюсь сохранить входы из jsp, который также включает дату. Я не могу найти, где ошибка.

public class Booking { 

    private int bId; 
    private String firstName; 
    private String lastName; 
    private Room room; 
    private Date checkinDate; 
    private int totalNights; 
    private Date checkoutDate; 
    private int totalPrice; 
    private Customer customer; 
    private boolean status; 

    public Booking() { 
    } 

    public Booking(int bId, String firstName, String lastName, Room room, Date checkinDate, int totalNights, Date checkoutDate, int totalPrice, Customer customer, boolean status) { 
     this.bId = bId; 
     this.firstName = firstName; 
     this.lastName = lastName; 
     this.room = room; 
     this.checkinDate = checkinDate; 
     this.totalNights = totalNights; 
     this.checkoutDate = checkoutDate; 
     this.totalPrice = totalPrice; 
     this.customer = customer; 
     this.status = status; 
    } 

    public int getbId() { 
     return bId; 
    } 

    public void setbId(int bId) { 
     this.bId = bId; 
    } 

    public String getFirstName() { 
     return firstName; 
    } 

    public void setFirstName(String firstName) { 
     this.firstName = firstName; 
    } 

    public String getLastName() { 
     return lastName; 
    } 

    public void setLastName(String lastName) { 
     this.lastName = lastName; 
    } 

    public Room getRoom() { 
     return room; 
    } 

    public void setRoom(Room room) { 
     this.room = room; 
    } 

    public Date getCheckinDate() { 
     return checkinDate; 
    } 

    public void setCheckinDate(Date checkinDate) { 
     this.checkinDate = checkinDate; 
    } 

    public int getTotalNights() { 
     return totalNights; 
    } 

    public void setTotalNights(int totalNights) { 
     this.totalNights = totalNights; 
    } 

    public Date getCheckoutDate() { 
     return checkoutDate; 
    } 

    public void setCheckoutDate(Date checkoutDate) { 
     this.checkoutDate = checkoutDate; 
    } 

    public int getTotalPrice() { 
     return totalPrice; 
    } 

    public void setTotalPrice(int totalPrice) { 
     this.totalPrice = totalPrice; 
    } 

    public Customer getCustomer() { 
     return customer; 
    } 

    public void setCustomer(Customer customer) { 
     this.customer = customer; 
    } 

    public boolean isStatus() { 
     return status; 
    } 

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

    @Override 
    public String toString() { 
     return "Booking{" + "bId=" + bId + ", firstName=" + firstName + ", lastName=" + lastName + ", room=" + room + ", checkinDate=" + checkinDate + ", totalNights=" + totalNights + ", checkoutDate=" + checkoutDate + ", totalPrice=" + totalPrice + ", customer=" + customer + ", status=" + status + '}'; 
    } 

}

Проверить, как только вы получили checkinDate/checkOutdate в контроллере может быть не из JSP
