    @RequestMapping("/secondSubPage")
    public class secondSubPageController {
        private static List<Travel> travels = new ArrayList<>();
     
        public static void main(String[] args) {
            Travel Wroclaw = new Travel("Wroclaw", "01-02-2001");
            Travel Krakow = new Travel("Kraków", "01-02-2001");
            Travel JeleniaGora = new Travel("Jelenia Góra", "01-02-2001");
            Travel Zgorzelec = new Travel("Zgorzelec", "01-02-2001");
            Travel Luban = new Travel("Lubań", "01-02-2001");
            Travel Lodz = new Travel("Lódz", "01-02-2001");
            Travel Karpacz = new Travel("Karpacz", "01-02-2001");

            Travel Katowice = new Travel("Katowice", "01-02-2001");
            Travel Miedzyzdroje = new Travel("Miedzyzdroje", "01-02-2001");
            travels.add(Wroclaw);
            travels.add(Krakow);
            travels.add(JeleniaGora);
