весенняя безопасность в веб-сервисе отдыха

Question

Я пытаюсь внедрить Spring Security в службу restweb.

Я всегда получаю сообщение " Вступление началось из-за неудачной аутентификации ".Это не входит в CustomAuthenticationProvider.java.Мой код возвращает меня от CustomEntryPoint.Я думаю, что есть неправильная конфигурация.

Answer 1

Похоже, что вы тормозите цепочку фильтров с этим customEntryPoint, потому что он запускается перед любой аутентификацией, и так как он отправляет response.sendError, цепочка, если она сломана.Итак, удалите этот bean-объект точки входа.
Вы можете зарегистрировать пользовательские обработчики успеха и ошибок, добавив их в sec: http secition:

<sec:form-login
        authentication-failure-handler-ref="authenticationFailedHandler"
        authentication-success-handler-ref="authenticationSuccessHandler" />

, где обработчик успеха:

@Component
public class AuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) throws IOException, ServletException {
        // success
    }
}

и неисправный обработчик:

@Component
public class AuthenticationFailedHandler extends SimpleUrlAuthenticationFailureHandler {

    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        // super.onAuthenticationFailure(request, response, exception);    
        // failed
    }
}

Надеюсь, это поможет.
