L'application Spring Boot utilisant MySQL s'arrête soudainement

Question

我在 application.properties 中有这个：

spring.datasource.url=jdbc:mysql://lin-05779-94506-mysql-primary.servers.linodedb.net:3306/mystic_rivers_db
spring.datasource.username=mystic_rivers_usr
spring.datasource.password=****

这是我在日志中看到的内容：

Answer 1

Le Tomcat intégré démarre-t-il ? Est-il inclus dans le chemin de classe ?

Si le conteneur de servlet n'est pas démarré, le thread principal se termine et l'application se ferme.
