Answer 1

Звучит так, как будто есть проблема пути.Я полагаю, что ваш "основной" метод находится в другом пакете в качестве вашего сервиса.Обычно он сканирует основной пакет и его подпакеты при выполнении функции автоматической настройки весенней загрузки для зависимостей пути к классам.

Но я думаю, что вы должны использовать @EnableJpaRepositories, чтобы определить, где находится репозиторий (вне основного пакета)

Пример:

package1.package2.repoclass
package1.package3.mainclass
package1.package3.serviceclass (Служба внедряет репозиторий)

При запуске сервера будет сообщение об ошибке, что служба не может внедрить репо, но когда я использую @EnableJpaRepositories(basePackages = "package1.package2"), он работает
