I have a java application with spring-boot. My code started giving a StackOverFlow error in the authentication part, so through the logs I looked for the problem and realized it was in the following line

var authentication = manager.authenticate(authenticationToken);

I’ll put my code of what I tried to make this part of the authentication work

@Configuration
@EnableWebSecurity
public class SecurityConfiguration {

    @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("/authentication").permitAll();
                    req.anyRequest().authenticated();
                })
                .addFilterBefore(securityFilter, UsernamePasswordAuthenticationFilter.class)
                .build();
    }

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

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

@Component
public class SecurityFilter extends OncePerRequestFilter {

    @Autowired
    private TokenService tokenService;

    @Autowired
    private UserRepository repository;

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        var tokenJWT = recuperarToken(request);
        if (tokenJWT != null) {
            var subject = tokenService.getSubject(tokenJWT);
            var usuario = repository.findByEmail(subject);
            var authentication = new UsernamePasswordAuthenticationToken(usuario, null, usuario.getAuthorities());
            SecurityContextHolder.getContext().setAuthentication(authentication);
        }
        filterChain.doFilter(request, response);
    }

    private String recuperarToken(HttpServletRequest request) {
        var authorizationHeader = request.getHeader("Authorization");
        if (authorizationHeader != null) {
            return authorizationHeader.replace("Bearer ", "").trim();
        }

        return null;
    }

}

@RestController
@RequestMapping("/authentication")
public class AuthenticationController {
    @Autowired
    private AuthenticationManager manager;

    @Autowired
    private TokenService tokenService;

    @PostMapping
    public ResponseEntity efetuarLogin(@RequestBody @Valid UserDTO dados) {
        try {
            var authenticationToken = new UsernamePasswordAuthenticationToken(dados.email(), dados.password());
            var authentication = manager.authenticate(authenticationToken);
            System.out.println(authentication);
            var tokenJWT = tokenService.gerarToken((User) authentication.getPrincipal());
            return ResponseEntity.ok(new TokenJWT(tokenJWT));
        } catch (Exception e) {
            e.printStackTrace();
            return ResponseEntity.badRequest().body(e.getMessage());
        }
    }
}
