인프런 커뮤니티 질문&답변

Spring Security 가 3점대 버전으로 오면서 상당한 변화가 있습니다. 강의 내용을 따라 하다보니 순환참조나, 현재는 지원하지 않는 기능이 상당수 존재하였습니다. 현재 작업한 코드가 문제 해결에 많은 도움이 되면 좋겠어서 글을 첨부합니다.

SecurityConfig.class 입니다.

@Configuration
@EnableWebSecurity
@RequiredArgsConstructor
public class SecurityConfig{
    private final CustomAuthenticationManager customAuthenticationManager;
    private final UserFindPort userFindPort;
    private final Environment environment;

    @Bean
    public WebSecurityCustomizer webSecurityCustomizer() {
        return (web) -> web.ignoring().
                requestMatchers(new AntPathRequestMatcher("/h2-console/**"))
                .requestMatchers(new AntPathRequestMatcher( "/favicon.ico"))
                .requestMatchers(new AntPathRequestMatcher( "/css/**"))
                .requestMatchers(new AntPathRequestMatcher( "/js/**"))
                .requestMatchers(new AntPathRequestMatcher( "/img/**"))
                .requestMatchers(new AntPathRequestMatcher( "/lib/**"));
    }

    @Bean
    protected SecurityFilterChain filterChain(HttpSecurity http, HandlerMappingIntrospector introspector) throws Exception {
        http.csrf(AbstractHttpConfigurer::disable);
        http.authorizeHttpRequests(authorize ->
                        authorize.requestMatchers(new MvcRequestMatcher(introspector, "/**")).permitAll()
//                                requestMatchers(new MvcRequestMatcher.Builder(introspector).pattern(HttpMethod.GET, "/users/**")).permitAll()
//                                .requestMatchers(new MvcRequestMatcher(introspector, "/greeting")).permitAll()
//                                .requestMatchers(new MvcRequestMatcher(introspector, "/welcome")).permitAll()
//                                .requestMatchers(new MvcRequestMatcher(introspector, "/health-check")).permitAll()
//                                .requestMatchers(new MvcRequestMatcher.Builder(introspector).pattern(HttpMethod.POST, "/users")).permitAll()
                                .anyRequest()
                                .authenticated())
                .addFilter(getAuthenticationFilter())
                .httpBasic(Customizer.withDefaults());
        return http.build();
    }

    private AuthenticationFilter getAuthenticationFilter() {
        return new AuthenticationFilter(customAuthenticationManager, userFindPort, environment);
    }
}

requestMatcher에서 AntPathRequestMatcher, MvcRequestMatcher에 관한 설명은

부족하지만 https://velog.io/@dktlsk6/Spring-Security-RequestMatcher

에서 확인 가능하십니다.

CustomUserDetailService.class 입니다. 순환참조 문제가 발생하여 강의와 달리 새로 CustomService를 생성하여 implements 하였습니다.

@Component
@RequiredArgsConstructor
public class CustomUserDetailService implements UserDetailsService {
    private final UserFindPort userFindPort;
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        UserDto userByEmail = userFindPort.findUserByEmail(username);
        if (userByEmail == null) {
            throw new UsernameNotFoundException("User Not Found");
        }
        return new User(userByEmail.getEmail(), userByEmail.getEncPasswd(), true, true, true, true, new ArrayList<>());
    }
}

CustomAuthenticationManager.class 입니다. AuthenticationFilter의 AuthenticationManager로 사용할 것입니다.

@Component
@RequiredArgsConstructor
@Slf4j
public class CustomAuthenticationManager implements AuthenticationManager {
    private final CustomUserDetailService customUserDetailService;
    @Bean
    protected PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        UserDetails userDetails = customUserDetailService.loadUserByUsername(authentication.getName());
        if (!passwordEncoder().matches(authentication.getCredentials().toString(), userDetails.getPassword())) {
            throw new BadCredentialsException("Wrong password");
        }
        return new UsernamePasswordAuthenticationToken(userDetails.getUsername(), userDetails.getPassword(), userDetails.getAuthorities());
    }
}

AuthenticationFilter.class 입니다. 해당 부분은 강의와 차이점이 없습니다.

@Slf4j
public class AuthenticationFilter extends UsernamePasswordAuthenticationFilter {
    private final UserFindPort userFindPort;
    private final Environment environment;

    public AuthenticationFilter(AuthenticationManager authenticationManager, UserFindPort userFindPort, Environment environment) {
        super.setAuthenticationManager(authenticationManager);
        this.userFindPort = userFindPort;
        this.environment = environment;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        try {
            LoginRequestDto creds = new ObjectMapper().readValue(request.getInputStream(), LoginRequestDto.class);
            UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(creds.getEmail(),
                    creds.getPassword(), new ArrayList<>());
            return getAuthenticationManager().authenticate(token);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain,
                                            Authentication authResult) throws IOException, ServletException {
        String username = authResult.getName();
        UserDto user = userFindPort.findUserByEmail(username);
        if (user == null) {
            throw new UsernameNotFoundException(username);
        }
        log.debug("user id {}", user.getUserId());

        String token = Jwts.builder()
                .setSubject(user.getUserId())
                .setExpiration(new Date(System.currentTimeMillis() + Long.parseLong(environment.getProperty("token.expiration.time"))))
                .signWith(SignatureAlgorithm.HS512, environment.getProperty("token.secret"))
                .compact();
        response.addHeader("token", token);
        response.addHeader("userId", user.getUserId());
    }
}

아래는 실제 결과입니다.

404가 뜨는 이유는 login 성공시 redirect url을 설정해주지 않아서 /(루트) 경로로 이동해서입니다. 해당 경로와 매핑되는 resource나 api가 없기 때문에 해당 오류가 발생한것이므로 정상작동으로 생각하시면 됩니다.

아래는 잘못된 정보를 기입하여 실패 테스트 입니다. 추후 강의를 들으며 업데이트 하도록 하겠습니다.
