আমার বসন্ত প্রকল্পের কাস্টম প্রমাণীকরণের সরবরাহকারীতে, আমি লগড ব্যবহারকারীর কর্তৃপক্ষের তালিকাটি পড়ার চেষ্টা করছি, তবে আমি নিম্নলিখিত ত্রুটির মুখোমুখি হয়েছি:

স্ট্যাকওভারফ্লোতে এখান থেকে অন্যান্য বিষয়গুলি পড়া, আমি বুঝতে পারি যে ফ্রেমওয়ার্ক দ্বারা এই ধরণের অ্যাট্রিবিউট পরিচালনা করা হয়, তবে আমি আমার মামলার কোনও সমাধান বের করতে পারি না। কেউ বলতে পারে যে আমি কী ভুল করছি এবং এটি সংশোধন করার জন্য আমি কী করতে পারি?
আমার কাস্টম প্রমাণীকরণের সরবরাহকারীর কোডটি হ'ল:
@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<AutorizacoesUsuario> list = user.getAutorizacoes();
List <String> rolesAsList = new ArrayList<String>();
for(AutorizacoesUsuario role : list){
rolesAsList.add(role.getAutorizacoes().getNome());
}
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
for (String role_name : rolesAsList) {
authorities.add(new SimpleGrantedAuthority(role_name));
}
Authentication auth = new UsernamePasswordAuthenticationToken(username, password, authorities);
return auth;

else {
