Я новичок в SpringBoot. Я написал образец службы, которая принимает детали проекта и сохраняет их в базе данных postgres. Однако я не могу запустить свое приложение и не уверен, что не так. Я проверил иерархию пакетов, и вроде все в порядке. Любая помощь приветствуется.

Я не создавал таблицу в базе данных, я делаю это через JPA, когда отправляю запрос POST.
