Validando Token Recebido! (Rodrigo ajuda ae! )

..... [remover]

Token Service :

@Service
public class TokenService {

    @Value("${api.security.token.secret}")
    private String secret;

    public String gerarToken(Usuario usuario) {
        try {
            var algoritmo = Algorithm.HMAC256(secret);
            return JWT.create()
                    .withIssuer("API_Voll.med")
                    .withSubject(usuario.getLogin())
                    .withExpiresAt(dataExpiracao())
                    .sign(algoritmo);
        } catch (JWTCreationException exception){
            throw new RuntimeException("Erro ao gerar token JWT", exception);
        }
    }

    public String getSubject(String tokenJWT){
        try {
            var algoritmo = Algorithm.HMAC256(secret);
            return JWT.require(algoritmo)
                    .withIssuer("API Voll.med")
                    .build()
                    .verify(tokenJWT)
                    .getSubject();
        } catch (JWTVerificationException exception) {
            throw new RuntimeException("Token JWT inválido ou expirado!");
        }
    }

    private Instant dataExpiracao() {
        return LocalDateTime.now().plusHours(2).toInstant(ZoneOffset.of("-03:00"));
    }
}

Security Filter:

@Component
public class SecurityFilter extends OncePerRequestFilter {
    @Autowired
    private TokenService tokenService;
    @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);
        }

        filterChain.doFilter(request, response);
}

    private String recuperarToken(HttpServletRequest request) {
        var authorizationHeader = request.getHeader("Authorization");
        if (authorizationHeader == null) {
            throw new RuntimeException("Token JWT não enviado no cabeçalho Authorization!");
        }

        return authorizationHeader.replace("Bearer ", "");
    }
}
