невозможно преобразовать грязный spring-security-xml в конфигурацию на основе Java

Question

После обновления некоторых зависимостей в нашем проекте maven для запуска проекта с контейнерами jdk11 мне пришлось обновить SpringSecurity 4.0.x до 4.2.x. Поэтому я хотел попробовать и преобразовать грязный XML в правильный Java-конфиг.

Вход через / вход работает нормально, разрешения работают внутри веб-интерфейса приложения. Проблема, с которой я столкнулся, связана с межсерверной связью через REST. Отправка правильных учетных данных, как раньше, просто возвращает страницу входа в систему вместо запрошенного ресурса - это та точка, в которой я застрял. Я чувствую, что конфигурация является слишком сложной и запутанной в некоторых моментах из-за нескольких точек входа. но это было то, что я прочитал в официальной документации. Или есть более простой способ, и я просто считаю слишком сложным? Короче говоря, Java-Config ведет себя не так, как Java-Config, и я пока не понимаю, почему.
