Im trying to create my own LoginController so i can watch the data flow more closely, but either my post method is wrong or my controller is missing something.

Whenever I try to send a login request it skips my LoginController and goes straight toUserDetailsService implementation as a blank String or Im getting that raw password cannot be null.

Code :

@CrossOrigin(origins = "http://localhost:4200/")@RequiredArgsConstructor@RestController@RequestMapping("/login")public class LoginController {    private final MyUserDetailsService userDetailsService;a    private final UserService userService;    private final PasswordEncoderConfig passwordEncoder;    @PostMapping    public ResponseEntity<UserDTO> loginUser(@RequestBody LoginDTO request){            String unhashedPassword = request.getPassword();            String hashedPassword = passwordEncoder.passwordEncoder().encode(unhashedPassword);            String username = request.getUsername();            Optional<UserDTO> possibleUser = userService.getUserByNickNameAndPassword(username,hashedPassword);        if (possibleUser.isPresent()) {            return ResponseEntity.ok(possibleUser.get());        } else {            return ResponseEntity.notFound().build();        }    }}

@EnableWebSecurity@Configuration@RequiredArgsConstructorpublic class SecurityConfiguration {    private final MyUserDetailsService userDetailsService;    private final PasswordEncoder passwordEncoder;    protected void configure(AuthenticationManagerBuilder auth) throws Exception {        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder);    }    @Bean    public CorsConfigurationSource corsConfigurationSource() {        CorsConfiguration configuration = new CorsConfiguration();        configuration.setAllowedOrigins(Arrays.asList("http://localhost:4200"));        configuration.setAllowedMethods(Arrays.asList("GET","POST", "PUT", "DELETE, OPTIONS, PATCH"));        configuration.setAllowCredentials(true);        configuration.addAllowedHeader("*");        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();        source.registerCorsConfiguration("/**", configuration);        return source;    }    @Bean    public SecurityFilterChain securityFilterChainConfig(HttpSecurity http) throws Exception {        http            .csrf().disable()            .cors(corsConfigurationSource ->                corsConfigurationSource.configurationSource(corsConfigurationSource()))            .authorizeRequests(request ->                request                    .requestMatchers("/users/all").permitAll()                    .requestMatchers("/beers/propose").hasRole("USER")                    .requestMatchers("/beer-updates/**").permitAll()                    .requestMatchers("/topic/beer-updates/**").permitAll()                    .requestMatchers("/beers/**").permitAll()                    .requestMatchers("/register").permitAll()                    .requestMatchers("/login").permitAll()                    .anyRequest().authenticated())            .formLogin(login -> {                login.loginProcessingUrl("/login");                login.successForwardUrl("/beers/all");                login.failureUrl("/login");            });        return http.build();    }}

@RequiredArgsConstructor@Servicepublic class MyUserDetailsService implements UserDetailsService {    private final UserService userService;    @Override    public UserDetails loadUserByUsername(final String username) throws UsernameNotFoundException {        Optional<UserDTO> userDTO = userService.getUserByNickName(username);        if(userDTO.isPresent()) {            UserDTO foundUser = userDTO.get();            return org.springframework.security.core.userdetails.User                .withUsername(foundUser .getNickName())                .password(foundUser .getPasswordHash())                .roles((foundUser .getRole()))                .build();        }        throw  new NoSuchElementException("nie ma takiego uzytkownika");    }}
