项目启动java.sql.SQLException: The server time zone value ‘�й���׼ʱ��‘ is unrecognized or represents more

场景

本来是好好的，因某种原因，改了mysql驱动版本为由23改到19

<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.19</version>
</dependency>

就出现了下面问题

Disconnected from the target VM, address: '127.0.0.1:10914', transport: 'socket'
