Я новичок в весенней загрузке с kotlin. У меня ошибка при запуске приложения. Я искал различные решения в других ответах в Stackoverflow.
Но ответы не дали мне никаких решений.

APPLICATION FAILED TO START

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Моя application.properties
конфигурация следующая.
spring.datasource.url=jdbc:mysql://localhost/db_name
spring.datasource.username=db_user
spring.datasource.password=db_pass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
И build.gradle.kts
следующее.

Я понятия не имею, что не так.
