我正在嘗試從春季啟動連接MySQL數據庫，但出現以下錯誤：

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

我的application.properties文件看起來像

spring.datasource.url= jdbc:mysql://localhost:3306/db_carrepairmaster

spring.datasource.username=root

spring.datasource.password=root

spring.jpa.database=mysql

spring.datasource.platform=mysql

# Show or not log for each sql query

spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update): with "update" the database

# schema will be automatically updated accordingly to java entities found in

# the project

spring.jpa.hibernate.ddl-auto = update

Username 'root' and password 'root' is correct because I am able to log in into root from command line. I have tried everything from java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES) & How to grant all privileges to root user in MySQL 8.0

Unable to find what I am doing wrong. Please suggest me anything which can work for me.
