我试图获得失败的身份验证的确切动机（即错误的密码，用户不存在，等等）问题是，无论我如何尝试模拟此操作，我总是得到“需要完全身份验证才能访问此资源”，如何才能得到更详细的异常？提前准备！
这是我的密码：

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    UserService userService;

    @Autowired
    UnauthorizedCustomResponse unauthorizedCustomResponse;

    @Autowired
    AccessDeniedCustomResponse accessDeniedCustomResponse;

    @Autowired
    CryptographyService cryptographyService;

    @Override
    public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
        authenticationManagerBuilder
                .userDetailsService(userService)
                .passwordEncoder(cryptographyService.getCryptography());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.cors().and().csrf().disable()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                .antMatchers("/api/auth/signin", "/api/public/**", "/api/private/**").permitAll()
                .anyRequest().authenticated()
                .and()
                .exceptionHandling()
                .authenticationEntryPoint(unauthorizedCustomResponse)
                .accessDeniedHandler(accessDeniedCustomResponse)
                .and()
                .httpBasic();
    }

}

@Component
public class AccessDeniedCustomResponse implements AccessDeniedHandler {

    private final Logger logger = LogManager.getLogger(this.getClass());

    @Override
    public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException exception)
            throws IOException, ServletException {

        logger.error("Usuário não autenticado: {}", exception.getMessage());
        CustomException customException = new CustomException(CustomExceptionMessage.CUSTOM_EXCEPTION_NOT_MAPPED, exception);
        customException.flush(response);
    }
}

@Component
public class UnauthorizedCustomResponse implements AuthenticationEntryPoint {

    private final Logger logger = LogManager.getLogger(this.getClass());

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception)
            throws IOException, ServletException {

        logger.error("Acesso não autorizado: {}", exception.getMessage());
        CustomException customException = new CustomException(CustomExceptionMessage.ACCESS_DENIED, exception);
        customException.flush(response);

    }
}
