    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>

                         ${users.name}
                        ${users.surname}
                        ${users.gender}
                        ${users.weight}
                        ${users.height}
                        ${users.sport}
                        ${users.place}

Here is my controller method.

    @RequestMapping(value = "/user/search", method = RequestMethod.POST,produces = "text/plain;charset=UTF-8")
    public String listUsersSort(
            @RequestParam(value="weight") int weight,
            @RequestParam(value="gender") String gender,
            @RequestParam(value="place") String place,
            @RequestParam(value="age") int age,
            Model model, Principal principal)
    {

        System.out.println("int");
        if(weight<40 && gender.equals("") && place.equals("") && age<19)
        {
            model.addAttribute("users", new Users());
model.addAttribute("noparams", "Задайте параметры поиска");
return "searchingUser";
        }

        else{
    model.addAttribute("users", new Users());
        model.addAttribute("listUsersSort", usersService.listUsersSort(weight, gender, place, age, principal.getName()));
        model.addAttribute("allUserMess", this.dialogService.allNewMessForUser(principal.getName()));
        model.addAttribute("countOfFeedbacks", this.feedbackService.checkUnreadFedbacks().size());
        model.addAttribute("countOfNewUsers", this.usersService.countOfNewUsers());
        return "searchingUser";
        }}

You're getting the error because your code is somewhere in between using the form-backing bean, or binding the parameters from request. You should either remove the modelAttribute and path attributes from your form.

Or remove the @RequestParam annotated arguments from your request, and create a form-backing object with weight, age, place, gender properties, and add the object to the controller method signature annotated with @ModelAttribute("users")
