明明密码对的,被拒绝了,找了好久原因,后来发现将db.properties配置文件里的username改为jdbc.username就好了,可能是因为username被系统变量占用了。
当spring容器在进行启动的时候,会读取当前系统某些环境变量的配置,当前系统的用户名使用username来表示的,所以做好的方式是添加前缀,使用jdbc.username.

 

jdbc.username=root
jdbc.password=root
jdbc.url=jdbc:mysql://localhost:3306/db2?&useSSL=false&serverTimezone=UTC
jdbc.driverClassName=com.mysql.cj.jdbc.Driver
