I am building a web application based on hotel room booking and testing my REST API through postman and this @Future annotation from import jakarta.validation.constraints.Future; is giving me 500 response, while I tried to hit the link mentioned in the screenshot,I tried again by removing this @Future annotation and it is working perfectly, so please tell me if there is any alternative (for validating future checkOutDate should be greater than checkInDate) or solution for this issue.

I have used this @Future over one variable of entity, below is the code.

Booking.java

package com.Yash.Astoria.entities;

import jakarta.validation.constraints.Future;
import jakarta.persistence.*;
import jakarta.validation.constraints.Min;
import jakarta.validation.constraints.NotNull;
import lombok.Data;

import java.time.LocalDate;

@Data
@Entity
@Table(name = "bookings")
public class Booking {

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

    @NotNull(message = "CheckIn Date is required")
    private LocalDate checkInDate;

    @Future(message = "check out date must be in the future")
    private LocalDate checkOutDate;

    @Min(value = 1, message = "Atleast 1 adult should be selected")
    private int numOfAdults;

    @Min(value = 0, message = "Number of Childrens should not be less then 0")
    private int numOfChildren;

    private int totalNumOfGuests;

    private String bookingConfirmationCode;

    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "room_id")
    private Room room;

    public void getTotalNumberOfGuests(){
        this.totalNumOfGuests = this.numOfAdults + this.numOfChildren;
    }

    public void setNumOfAdults(int numOfAdults) {
        this.numOfAdults = numOfAdults;
        getTotalNumberOfGuests();
    }

    public void setNumOfChildren(int numOfChildren) {
        this.numOfChildren = numOfChildren;
        getTotalNumberOfGuests();
    }

    @Override
    public String toString() {
        return "Booking{" +
                "id=" + id +
                ", checkInDate=" + checkInDate +
                ", checkOutDate=" + checkOutDate +
                ", numOfAdults=" + numOfAdults +
                ", numOfChildren=" + numOfChildren +
                ", totalNumOfGuests=" + totalNumOfGuests +
                ", bookingConfirmationCode='" + bookingConfirmationCode + ''' +
                '}';
    }
}

BookingController.java

package com.Yash.Astoria.controllers;

import com.Yash.Astoria.dto.Response;

@RestController
@RequestMapping("/bookings")
public class BookingController {

    @Autowired
    private IBookingService bookingService;

    @PostMapping("/book-room/{roomId}/{userId}")
    @PreAuthorize("hasAuthority('ADMIN') or hasAuthority('USER')")
    public ResponseEntity<Response> saveBookings(@PathVariable Long roomId,
                                                 @PathVariable Long userId,
                                                 @RequestBody Booking bookingRequest){
        Response response = bookingService.saveBooking(roomId, userId, bookingRequest);
        return  ResponseEntity.status(response.getStatusCode()).body(response);
    }

    @GetMapping("/all")
    @PreAuthorize("hasAuthority('ADMIN')")
    public ResponseEntity<Response> getAllBookings(){
        Response response = bookingService.getAllBookings();
        return ResponseEntity.status(response.getStatusCode()).body(response);
    }

    @GetMapping("/get-by-confirmation-code/{confirmationCode}")
    public ResponseEntity<Response> getBookingByConfirmationCode(@PathVariable String confirmationCode){
        Response response = bookingService.findBookingByConfirmationCode(confirmationCode);
        return  ResponseEntity.status(response.getStatusCode()).body(response);
    }

    @DeleteMapping
    @PreAuthorize("hasAuthority('ADMIN') or hasAuthority('USER')")
    public ResponseEntity<Response> cancelBooking(@PathVariable Long bookingId){
        Response response = bookingService.cancelBooking(bookingId);
        return ResponseEntity.status(response.getStatusCode()).body(response);
    }

}

Expectation: validating future checkOutDate should be greater than
checkInDate

Also, I have tried @FutureOrPresent annotation, and it give the same error
