Bounty: 100

private PasswordEncoder passwordEncoder;

private OldPasswordsService oldPasswordsService;

Optional<OldPasswords> list = oldPasswordsService.findEncryptedPassword(passwordEncoder.encode("new password entered form web reset form"));
            OldPasswords value = list.get();
            boolean matches = passwordEncoder.matches("new password entered form web reset form", value.getEncryptedPassword());

            if (matches)
                return new ResponseEntity<>("PASSWORD_ALREADY_USED", HttpStatus.BAD_REQUEST);
                OldPasswords oldPasswords = new OldPasswords();

Table for old passwords:

@Table(name = "old_passwords")
public class OldPasswords implements Serializable {

    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", unique = true, updatable = false, nullable = false)
    private int id;

    @Column(name = "encrypted_password", length = 255)
    private String encryptedPassword;

But I get java.util.NoSuchElementException: No value present.
Do you know how I can implement a logic which compares old and new passwords?
