커스텀 필터 적용 안됨

Question

강의를 다 수강하고 깃허브 코드 참조하여 작성했습니다. 현재 SecurityConfig 코드는 다음과 같습니다. @Configuration @EnableWebSecurity @RequiredArgsConstructor public class SecurityConfig{ private final UserRepository userRepository; private final CorsConfig corsConfig; @Bean public SecurityFilterChain filterChain(HttpSecurity http) throws Exception { return http .csrf(AbstractHttpConfigurer::disable) .sessionManagement((sessionManagement) -> sessionManagement.sessionCreationPolicy(SessionCreationPolicy.STATELESS) ) .formLogin(withDefaults()) .httpBasic(withDefaults()) .apply(new MyCustomDsl()) .and() .authorizeRequests(requests -> requests .requestMatchers("/user/**").authenticated() .requestMatchers("/admin/**").access("hasAuthority('ADMIN')") .anyRequest().permitAll() ) .build(); } public class MyCustomDsl extends AbstractHttpConfigurer<MyCustomDsl, HttpSecurity> { @Override public void configure(HttpSecurity http) throws Exception { AuthenticationManager authenticationManager = http.getSharedObject(AuthenticationManager.class); http .addFilter(corsConfig.corsFilter()) .addFilter(new JwtAuthenticationFilter(authenticationManager)) .addFilter(new JwtAuthorizationFilter(authenticationManager, userRepository)); } } } filterchain에서 and()에 오류가 발생합니다. 'and()' is deprecated and marked for removal 로 나오는데 and가 deprecated된 거 같지는 않고 커스텀 필터를 적용하는 것에서 뭔가 문제가 있지 않을까 싶습니다만 이틀째 해결을 못하고 있어 문의남깁니다ㅠㅠ

@Bean public SecurityFilterChain filterChain(HttpSecurity http) throws Exception { AuthenticationManager authenticationManager = http.getSharedObject(AuthenticationManager.class); return http .csrf(AbstractHttpConfigurer::disable) .sessionManagement((sessionManagement) -> sessionManagement.sessionCreationPolicy(SessionCreationPolicy.STATELESS) ) .formLogin(withDefaults()) .httpBasic(withDefaults()) .addFilter(corsConfig.corsFilter()) .addFilter(new JwtAuthenticationFilter(authenticationManager)) .addFilter(new JwtAuthorizationFilter(authenticationManager, userRepository)) .authorizeRequests(requests -> requests .requestMatchers("/user/**").authenticated() .requestMatchers("/admin/**").access("hasAuthority('ADMIN')") .anyRequest().permitAll() ) .build(); } 커스텀 필터를 적용 안하고 커스텀 필터에 코드를 filterchain에 작성하면 어떨까 싶어 위와 같이 작성해보았었으나, 빨간 줄은 안 뜨지만 디버깅해보니 authenticationManager가 null이라고 나왔었습니다..
