Я пытаюсь запустить свой Spring Boot backend с двумя профилями: один использует H2 в базе данных памяти, а второй - MySQL.База данных H2 работает просто отлично, но когда я переключаюсь на MySQL, я получаю
APPLICATION FAILED TO START
***************************
Description:
Failed to bind properties under '' to com.zaxxer.hikari.HikariDataSource:
Property: driverclassname
Value: com.mysql.jdbc.Driver;
Origin: "driverClassName" from property source "source"
Reason: Failed to load driver class com.mysql.jdbc.Driver; in either of HikariConfig class loader or Thread context classloader
Action:
Update your application's configuration
Я пытался удалить .m2, повторно импортировать, maven clean, скомпилировать, установить и большинство вещей, которые я мог найти в Интернете,нет успехаСамое смешное, что у меня есть другой проект только с базой данных MySQL, у меня была похожая проблема, но добавление зависимости mysql-connector-java решило ее.Я понятия не имею сейчас.
