Ich versuche, eine Verbindung zur MySQL-Datenbank herzustellen, aber es funktioniert nicht. Ich nahm einen Kurs von Udemy und befolgte alle Schritte, aber ich bekomme immer den gleichen Fehler, dann folgte ich den Schritten von this und this Anleitungen, aber funktioniert nicht.Spring-Boot und MySql kann keine Verbindung herstellen
Dinge, die ich bisher versucht:
- neue IDE
- sauber & Wiederaufbau Projekt
- Eigenschaft Löschen
spring.datasource.driverClassName = com.mysql.jdbc.Driver
vonapplication.properties
- versucht MySQL Connector manuell
hinzufügenMir sind die Ideen ausgegangen.Stacktrace
