I am creating a Spring boot application for booking flights. I have a home page, where flight details are displayed in a table using thymeleaf as below:

<table border="solid">
    <tr>
        <th>Airline</th>
        <th>Flight Number</th>
        <th>Departure</th>
        <th>Arrival</th>
        <th>Date</th>
        <th>Seats available</th>
        <th>Price</th>
                
    </tr>
            
    <tr th:each="flight : ${flightList}">
        <td th:text="${flight.airlineName}"></td>
        <td th:text="${flight.flightNumber}" th:field="*{flightNumber}"></td>
            <td th:text="${flight.departure}"></td>
            <td th:text="${flight.arrival}"></td>
        <td th:text="${flight.date}"></td>
        <td th:text="${flight.availableSeats}"></td>
        <td th:text="${flight.price}"></td>
                
        </tr>
            
</table>

I am trying to fetch the specific flight using the flight number and pass it as parameter to the controller in order to display it on the next page.

@GetMapping("/booking-page")
public String getBookingPage(@RequestParam("flightNumber") String flightNumber) {
    flightService.findFlightByFlightNumber(flightNumber);
    return "bookFlight";
}

It is not working though. Any alternative?
