解决办法

修改加密规则为普通模式，默认是严格加密模式

1. 进入mysql控制面板，输入mysql -uroot -p，输入密码
2. 在控制面板上依次输入
   • 修改加密规则

   ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; 
   

   • 更新用户密码

   ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
   

   • 刷新权限

   FLUSH PRIVILEGES;
   

3. 输入刚刚修改的密码，再次测试连接即可。
