Di AuthenticationProvider kustom dari proyek musim semi saya, saya mencoba membaca daftar otoritas pengguna yang login, tetapi saya menghadapi kesalahan berikut:
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.horariolivre.entity.Usuario.autorizacoes, could not initialize proxy - no Session

Membaca topik lain dari sini di StackOverflow, saya mengerti ini terjadi karena cara atribut jenis ini ditangani oleh kerangka kerja, tetapi saya tidak dapat menemukan solusi apa pun untuk kasus saya. Seseorang dapat menunjukkan kesalahan yang saya lakukan dan apa yang dapat saya lakukan untuk memperbaikinya?
Kode dari Custom AuthenticationProvider saya adalah:
@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 {
return null;
}
} else {
return null;
}
}
@Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
