스프링 시큐리티 문의 (webSecurityConfigurerAdapter 취소선)

authenticationManager 빈을 하나 생성하셔서 사용하시면 될 것 같습니다.@Bean AuthenticationManager authenticationManager(AuthenticationConfiguration authConfiguration) throws Exception { return authConfiguration.getAuthenticationManager(); } @Bean public SecurityFilterChain configure(HttpSecurity http) throws Exception { AuthenticationManager authenticationManager = authenticationManager(http.getSharedObject(AuthenticationConfiguration.class)); http.~~~ .addFilter(getAuthenticationFilter(authenticationManager)); return http.build(); } private AuthenticationFilter getAuthenticationFilter(AuthenticationManager authenticationManager) { AuthenticationFilter authenticationFilter = new AuthenticationFilter(authenticationManager); return authenticationFilter; } 또는@Bean public SecurityFilterChain configure(HttpSecurity http) throws Exception { http.~~~ .addFilter(getAuthenticationFilter(http)); return http.build(); } private AuthenticationFilter getAuthenticationFilter(HttpSecurity http) { AuthenticationFilter authenticationFilter = new AuthenticationFilter(http.getSharedObject(AuthenticationConfiguration.class)); return authenticationFilter; }이렇게 추가하시고AuthenticationFilter에서는@RequiredArgsConstructor public class AuthenticationFilter extends UsernamePasswordAuthenticationFilter{ private final AuthenticationManager authenticationManager; //attemptAuthentication //successAuthentication }이렇게 적용해보시면 될 듯합니다.
