如何在grails 2.2.3中为Spring Security启用日志记录？
我想看看 Spring 安全的完整日志。我尝试在onAuthenticationFailure方法上处理它，但没有成功

public void onAuthenticationFailure(final HttpServletRequest request, final HttpServletResponse response,
            final AuthenticationException exception) throws IOException, ServletException {

        ObjectMapper objectMapper = new ObjectMapper();

        if (SpringSecurityUtils.isAjax(request)) {
            saveException(request, exception);
            getRedirectStrategy().sendRedirect(request, response, _ajaxAuthenticationFailureUrl);
        }
        else {
            super.onAuthenticationFailure(request, response, exception);
        }

    }
