Probleme beim Verbinden des Spring Boot-Projekts mit der PostgreSQL-Datenbank ⇐ Java

[Guest]

Ich arbeite an einem Spring Boot-Projekt, das eine Verbindung zu einer PostgreSQL-Datenbank herstellt, aber es treten Probleme beim Einrichten der Datenbankverbindung auf. Die Protokolle zeigen Folgendes:

Der Datenbanktreiber wird als „undefiniert/unbekannt“ gemeldet.

Es gibt Warnungen im Zusammenhang mit Hibernate, insbesondere zum Dialekt und zur JTA-Plattform. Der Hikari-Verbindungspool zeigt nicht die erwartete Konfiguration an, z. B. Poolgröße, Isolationsstufe und Autocommit-Modus.
Ich habe die PostgreSQL-Abhängigkeit bereits hinzugefügt, aber die Verbindung scheint immer noch vorhanden zu sein Probleme beim Start. Kann jemand bei der Fehlerbehebung bei der Einrichtung helfen oder zusätzliche Konfigurationsschritte vorschlagen, um dieses Problem zu beheben?
