How to take the time from Java Thymeleaf and send it to the controller? What is the type of parametar? (JAVA)

Question

I am new to Java spring and i am learning how to make reservations. I have assignment to make a web application that helps clients to make reservation in certain coffee that they choose. I have booking form where there is a input for date ,time and for how many people is the reservation. Here is the input field in HTML where i insert only the time.

<input type="time" id="appt" min="09:00" max="21:00"  class="form-control" step="60" name="time">

My question is what type should i make the time parametar in the controller. Here is also example of the format that is passed for time parametar when i insert 12:00 PM to the input field: time=12:00 What should i change in my controller to start working?

   @PostMapping( "/book")
    public String makeReservation(Model model,
                              @RequestParam Long objectId,
                              @RequestParam Integer numPersons,
                              @RequestParam  String date,
                               @RequestParam   String  time) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
LocalDate localDate=LocalDate.parse(date,formatter);
        LocalDateTime localDateTime = LocalDateTime.parse(time);

        return "master-template";
    }

Previous i was using java.sql.Time but now i am trying to parse the String time to LocalDateTime but it shows me this error

java.time.format.DateTimeParseException: Text '12:00' could not be parsed at index 0

Here is the solution how to pass the time while passing it by field input with type=time

   @PostMapping("/book")
        public String makeReservation(Model model,
                                      @RequestParam Long objectId,
                                      @RequestParam Integer numPersons,
                                      @RequestParam String date,
                                      @RequestParam String time) {
            DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
            LocalDate localDate = LocalDate.parse(date, formatter);
            LocalTime localTime = LocalTime.parse(time);
    
            return "redirect:/home";
        }
