Проблемы с подключением проекта Spring Boot к базе данных PostgreSQL. ⇐ JAVA

[Anonymous]

Я работаю над проектом Spring Boot, который подключается к базе данных PostgreSQL, но у меня возникли проблемы с настройкой подключения к базе данных. В журналах отображается следующее:

Драйвер базы данных отображается как «неопределенный/неизвестный».

Есть предупреждения, связанные с Hibernate, в частности, с диалектом и платформой JTA. Пул соединений Hikari не отображает ожидаемую конфигурацию, такую ​​как размер пула, уровень изоляции и режим автофиксации.
Я уже добавил зависимость PostgreSQL, но соединение, похоже, все еще не работает. проблемы во время запуска. Может ли кто-нибудь помочь устранить неполадки при настройке или предложить дополнительные действия по настройке для решения этой проблемы?
