Jdbc function of delete

public int deleteUser(int id){
        String SQL = "DELETE FROM users WHERE id = '"+id+"'";
        System.out.print(SQL);
        int user = jdbcTemplateObject.update(SQL, id);
        return user;
    }

delete controller

RequestMapping(value = "/delete", method = RequestMethod.GET)
    public ModelAndView delete(@ModelAttribute("SpringWeb")User user, ModelMap model, HttpServletRequest request)
    {
        try
        {
            SyntacksJdbc syntacksJdbc = (SyntacksJdbc)context.getBean("syntacksJdbc");
            System.out.println(request.getParameter("id"));
            int id = Integer.parseInt(request.getParameter("id"));
            int user1 = syntacksJdbc.deleteUser(id);
            model.addAttribute("message", "Questions updated successfully.");
        }
        catch(Exception e)
        {
            System.out.print(e);
