So as the title says I can’t connect to my database through spring-boot the database seems to be working fine in PHPMyAdmin and in the workbench in PHPMyAdmin I checked the user setting and user root has all privileges enabled I’m guessing its something with MySQL I’m using MySQL 8. This Is a school project so I’m not really sure where the problem is any help would be appreciated
the error log
java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO)
