Lesen anderer Themen von hier aus Stackoverflow.  Ich verstehe, dass dies aufgrund dieser Art von Attribut durch das Framework geschieht, aber ich kann keine Lösung für meinen Fall herausfinden.  Jemand kann zeigen, was ich falsch mache und was ich tun kann, um es zu beheben?@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {

@Autowired
private UsuarioHome usuario;

public CustomAuthenticationProvider() {
super();
}

@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
System.out.println("CustomAuthenticationProvider.authenticate");

String username = authentication.getName();
String password = authentication.getCredentials().toString();

Usuario user = usuario.findByUsername(username);

if (user != null) {
if(user.getSenha().equals(password)) {
List list = user.getAutorizacoes();

List  rolesAsList = new ArrayList();
for(AutorizacoesUsuario role : list){
rolesAsList.add(role.getAutorizacoes().getNome());
}

List authorities = new ArrayList();
for (String role_name : rolesAsList) {
authorities.add(new SimpleGrantedAuthority(role_name));
}

Authentication auth = new UsernamePasswordAuthenticationToken(username, password, authorities);
return auth;
