Получить данные с формы для регистрации

Делаю проект на SpringBoot, форму для регистрации и логирования сделал на Freemaker. Так вот, хочу проверить совпадают ли данные в полях пароль и подтверждения пароля, но не очень понимаю как получить данные с формы. На данный момент есть код формы и обработка некоторых запросов. И еще вопрос, как в случае несовпадения введенных данных вывести сообщение об ошибке?
