Spring использует провайдера анонимной аутентификации для использования гостевого пользователя

Я использую Spring framework с безопасностью в своем веб-приложении. У меня есть гостевой пользователь и его привилегии в моем db, но я не могу реализовать AnonymousAuthenticationFilter и AnonymousAuthenticationProvider для использования этого пользователя. Вот моя конфигурация appSecurity:

И вот мой пользовательский анонимный поставщик аутентификации:

package com.asosyalbebe.springtest.gui.user.security;

import org.springframework.security.authentication.AnonymousAuthenticationProvider;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;

import com.asosyalbebe.springtest.gui.user.model.GuiUser;
import com.asosyalbebe.springtest.gui.user.service.UserService;

@SuppressWarnings("deprecation")
public class CustomAnonymousAuthProvider extends AnonymousAuthenticationProvider {
    private UserService userDetailsService;

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        GuiUser user = userDetailsService.getGuestUser();

        UsernamePasswordAuthenticationToken result = new UsernamePasswordAuthenticationToken(user, "pwd", user.getAuthorities());
        result.setDetails(user);

        return result;
    }

    @Override
    public boolean supports(Class<?> class1) {
        return true;
    }

    public void setUserDetailsService(UserService userDetailsService) {
        this.userDetailsService = userDetailsService;
    }
}

Я думаю, что метод authenticate в CustomAnonymousAuthProvider никогда не выполняется. Что еще я могу сделать?
