mysql8.0 Authentication plugin 'caching_sha2_password' cannot be loaded

測試類報錯，看提示應該是數據庫連接的問題。最後在一個網站上找到了解決方案:

8.0改變了身份驗證插件，改成使用老版本的身份驗證插件方式就好了。

cd "C:\Program Files\MySQL\MySQL Server 8.0\bin"

C:\Program Files\MySQL\MySQL Server 8.0\bin> mysql -u root -p
Enter password: *********

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newrootpassword';
Query OK, 0 rows affected (0.10 sec)

mysql> exit
