java - 获取 org.springframework.security.authentication.BadCredentialsException: Bad credentials exception Spring security

Question

嗨，我正在尝试手动进行身份验证，并希望为 Spring 安全性保存用户详细信息。但是我在下面给出的代码中遇到了这个异常

Authentication auth = authManager.authenticate(authReq);

例外 -

org.springframework.security.authentication.BadCredentialsException: Bad credentials

服务方式——

@Service
public class UserServiceImpl implements UserService {

@Autowired
private AuthenticationManager authManager;

@Override
public Boolean authenticateUser(User user) {
    String password = Utils.generateOtp(6).toString();
    user.setPassword(password);

    UsernamePasswordAuthenticationToken authReq = new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword());
    Authentication auth = authManager.authenticate(authReq);

    SecurityContextHolder.getContext().setAuthentication(auth);
    return true;
}

}

您如何针对 jdbc 或内存对用户进行身份验证？请检查是否有任何密码加密？
