二、no dirver files provided com.mysql.cj.jdbc.Driver
Error: no dirver files provided,
Reason: When pycharm imports the MySQL driver , it cannot recognize it successfully and displays red fonts.
Solution: Click the blue reminder box Config Driver. After jumping to the page, click to download the driver version according to the process shown in the figure below (here I downloaded version 8.0.21).
Just wait here to download the driver.
Then you can also delete the redundant 8.0.29 version imported before to avoid confusion.

三、Server returns invalid timezone. Need to set 'serverTimezone' property.
Error: When creating a new Mysql connection, an exception is prompted during the "Test Connection" test.
Reason: This situation occurs because the time zone is not configured when installing MySQL. The default time zone in the MySQL-driven jar package is UTC, which represents global standard time, but the time we use is the Beijing time zone, which is the East Eighth District, eight hours ahead of UTC, which is obviously a mismatch. Because the time zone is inconsistent, an invalid time zone is returned, which leads to the above problem.
Workaround: Specify the current time zone for the database.
Configure the time zone in config, click [Set time zone], jump to the [Advanced] tab and manually set the [serverTimezon] attribute value.
Change the default attribute "UTC" of [serverTimezon] to "GMT" and remember to click "Apply" to take effect;
OK, finally solved.
