ใน AuthenticationProvider แบบกำหนดเองจากโครงการฤดูใบไม้ผลิของฉันฉันกำลังพยายามอ่านรายชื่อหน่วยงานของผู้ใช้ที่เข้าสู่ระบบ แต่ฉันพบข้อผิดพลาดต่อไปนี้:

อ่านหัวข้ออื่น ๆ จากที่นี่ใน StackOverflow ฉันเข้าใจว่าสิ่งนี้เกิดขึ้นเนื่องจากกรอบการทำงานของ atribute ประเภทนี้จัดการ แต่ฉันไม่สามารถหาวิธีแก้ปัญหาใด ๆ สำหรับกรณีของฉัน ใครบางคนสามารถชี้ว่าฉันทำอะไรผิดและฉันจะแก้ไขอะไรได้บ้าง?
รหัสของ Custom AuthenticationProvider ของฉันคือ:
@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);
}
}
