Не срабатывает BindingResult (Spring MVC c JSP )

Не срабатывает валидации на странице. Не могу найти причину, мой код:

Класс модели:

public class User {
 private Long id;
 @NotBlank(message = "The login can't be empty and has whitespace",
        groups = {NotEmpty.class, NotNull.class})
 @Pattern(regexp = "/^[A-Za-z0-9]+$/",
        message = "The login has to have only English symbols")
 private String username;
 @Pattern(regexp = "/(?=.*[0-9])(?=.*[!@#$%^&*])(?=.*[a-z])(?=.*[A-Z])[0-9a-zA-Z!@#$%^&*]{6,}",
        message = "The password has to hava more 6 symbols, has at least 1 uppercase letter and special character")
 private String password;
 @NotBlank(message = "Your name can't have whitespace")
 @Size(min = 3, message = "Your name has to have more 3 character")
 private String name;
//getters and setters with constructors
}

Классы конфигурации:

@Configuration
public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
 @Override
 protected Class<?>[] getRootConfigClasses() {
    return null;
 }
 @Override
 protected Class<?>[] getServletConfigClasses() {
    return new Class[]{WebConfig.class};
 }

 @Override
 protected String[] getServletMappings() {
    return new String[]{"/"};
 }
}

и

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "ua.zakharov.application")
public class WebConfig implements WebMvcConfigurer {
 @Bean
 InternalResourceViewResolver jspViewResolver(){
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/view/");
    resolver.setSuffix(".jsp");
    return resolver;
 }

}

Класс контроллер:

@Controller
@RequestMapping("/registration")
 public class RegistrationController {
 @Autowired
 private UserService userService;

 @GetMapping
 public String getRegistrationPage(Model model) {
    model.addAttribute("userForm", new User());
    return "registration";
 }

 @PostMapping String createNewUser( @ModelAttribute("userForm") @Valid User user,
                                  BindingResult bindingResult) {
    if (bindingResult.hasErrors()) {
        return "registration";
    }

    userService.save(user);
    return "redirect:/login";
 }
}

Использую в качестве валидатора следующую зависимость:

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-validator</artifactId>
  <version>6.1.0.Final</version>
</dependency>

Контроллер отрабатывает, модель с данным поступает, но не срабатывает блок с валидацией.
