Spring MVC controller doesn't handle submit from Thymeleaf

Question

I created simple Thymeleaf form template for user registration. When I hit submit form button, POST request is sent (as I see from browser log), but it never handled by saveRegistration controller method, annotated with (method = RequestMethod.POST)

Spring version 4.2.2 , Spring security 4.0.2, Spring boot starter 1.2.7 Model object uses Hibernate validators (if it make sense)

Controller code:

package org.vmtest.web.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.vmtest.web.model.User;

import javax.validation.Valid;
import java.util.*;

/**
 * Created by victor on 24.10.15.
 */
@Controller
@RequestMapping("/register")
public class RegistrationController {

    @RequestMapping(method = RequestMethod.GET)
    public String newRegistration(ModelMap model) {
        User user = new User();
        model.addAttribute("user", user);
        return "register";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String saveRegistration(@Valid User user, BindingResult result, ModelMap model){

        if(result.hasErrors()) {
            return "register";
        }

        model.addAttribute("success", "Dear "+ user.getFirstName()+" , your Registration completed successfully");
        return "redirect:/login";
    }

    @ModelAttribute("countries")
    public Map<String, String> initializeCountries() {

        Map<String, String> countries = new TreeMap<>();

        String[] locales = Locale.getISOCountries();
        for (String countryCode : locales) {
            Locale obj = new Locale("", countryCode);
            countries.put(obj.getDisplayCountry(), obj.getCountry());
        }

        return countries;
    }

}

Thymeleaf template:

<!DOCTYPE html>

I think it works but you dont get the success message printed in the user login page.

It's because you are setting a model attribute and redirecting to another page.

  model.addAttribute("success", "Dear "+ user.getFirstName()+" , your Registration completed successfully");
  return "redirect:/login";

I don't think if this happens, you will get the model attribute pass to the redirected page.

Rather you may use Redirect Attributes https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/mvc/support/RedirectAttributes.html

@RequestMapping(method = RequestMethod.POST)
 public String saveRegistration(@Valid User user, BindingResult result, RedirectAttributes redirectAttrs) {
    if(result.hasErrors()) {
        return "register";
    }
    redirectAttrs.addAttribute("success", "Dear "+ user.getFirstName()+" , your Registration completed successfully");
    return "redirect:/accounts/{id}";
 }
