Olá meu método gerarToken não compila, avaliei tudo que pude e não sei onde estou errando:

@RestController @RequestMapping("/auth") public class AutenticacaoController {

@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private TokenService tokenService;

@PostMapping
public ResponseEntity<?> autenticar(@RequestBody @Valid LoginForm form) {

    try {
        UsernamePasswordAuthenticationToken dadosLogin = form.converter();

        Authentication authentication = authenticationManager.authenticate(dadosLogin);
        System.out.println("autentication: " + authentication);
        String token = tokenService.gerarToken(authentication);

        System.out.println("gerarToken: " + token);
        return ResponseEntity.ok().build();

    } catch (AuthenticationException e) {
        return ResponseEntity.badRequest().build();
    }

}

}

@Service public class TokenService {

@Value("${forum.jwt.expiration}")
private String expiration;

@Value("${forum.jwt.secret}")
private String secret;

public String gerarToken(Authentication authentication) {

    Usuario logado = (Usuario) authentication.getPrincipal();
    Date hoje = new Date();

    Date dataExpiracao = new Date(hoje.getTime() + Long.parseLong(expiration));

    System.out.println("dataExpiracao: " + dataExpiracao);

    return Jwts.builder().setIssuer("API do fórum da Alura").setSubject(logado.getId().toString()).setIssuedAt(hoje)
            .setExpiration(dataExpiracao).signWith(SignatureAlgorithm.HS256, secret).compact();
}

}

No console aparece:

APPLICATION FAILED TO START

Description:

Field tokenService in br.com.alura.forum.controller.AutenticacaoController required a bean of type 'org.springframework.security.core.token.TokenService' that could not be found.

The injection point has the following annotations:

- @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'org.springframework.security.core.token.TokenService' in your configuration.

No entanto na Classe AutenticacaoController eu tenho o import :

package br.com.alura.forum.controller;
