万能的out net，奈何国内没文档-java.sql.SQLException: Access denied for user ‘‘@‘localhost‘ (using password:YES)

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

毋庸置疑，这这种错误，一定是数据库的配置问题，所以检查你的properties或者yml文件
注意其中的username而不是name。

Solution: pay attention to the username or name. I think some configurations are username and name (I reported this error because I wrote username as name)

附上实例文档 application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/db01?serverTimezone=UTC&userUnicode=true&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
