CORS não desabilita | Spring Boot 3: aplique boas práticas e proteja uma API Rest

Fala pessoal construi um projeto front-end para consumir a API que fiz nesse curso. Só que estou com problemas para se comunicar com a API.

Insira aqui a descrição dessa imagem para ajudar na acessibilidade

Mas eu inclui um codigo referente a desabilitar o CORS, mas não está funcionando!!! Minha classe SecurityConfigurations:

package br.com.jeff.restescola.infra.security;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.SecurityFilterChain;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@Configuration
@EnableWebSecurity
public class SecurityConfigurations {

    @Autowired
    private SecurityFilter securityFilter;

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        return http.csrf(csrf -> csrf.disable())
                .sessionManagement(sm -> sm.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
                .authorizeHttpRequests(req -> {
                    req.requestMatchers(HttpMethod.POST, "/login").permitAll();
                    req.anyRequest().authenticated();
                })
                .addFilterBefore(securityFilter, UsernamePasswordAuthenticationFilter.class)
                .build();
    }

    @Bean
    public AuthenticationManager authenticationManager(AuthenticationConfiguration configuration) throws Exception {
        return configuration.getAuthenticationManager();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

// Peguei esse metodo em uma duvida aqui mesmo no FORUM

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.addAllowedOrigin("http://localhost:3000");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        source.registerCorsConfiguration("/**", config);
        return new CorsFilter(source);
    }
}

Alguem poderia ajudar?

Consegui resolver meu problema....

Vou compartilhar a solução!!!!

Na classe SecurityConfiguration Eu aidiconei uma configuração de Customizer. No metodo SecurityFilterChain ficou assim:

 @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        return http.csrf(csrf -> csrf.disable())
                .cors(Customizer.withDefaults()) // Adicionei essa linha no metodo
                .sessionManagement(sm -> sm.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
                .authorizeHttpRequests(req -> {
                    req.requestMatchers(HttpMethod.POST, "/login").permitAll();
                    req.anyRequest().authenticated();
                })
                .addFilterBefore(securityFilter, UsernamePasswordAuthenticationFilter.class)
                .build();
    }

Não esqueça de utilizar esse import:

import org.springframework.security.config.Customizer;

Em seguida eu criei essa class:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class CorsConfiguration {
    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**");
            }
        };
    }
}

Com isso consegui resolver meu problema!!!!
