Распаковка XML в список списков в JAXB

Я создал класс помощника, чтобы сделать мою жизнь легкой. Это общий класс и имеет множество методов, которые обычно используются в таких приложениях, как «Общие настройки», «Срок действия электронной почты», «Формат даты». Скопируйте этот класс в свой код и получите доступ к его методам везде, где вам нужно.
