错误描述：You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

检查发现是数据库驱动（升级）有错误
问题原因：
升级后的mysql驱动类，Driver位置由com.mysql.jdbc.Driver 变为com.mysql.cj.jdbc.Driver
解决方案：
将数据配置文件里spring.datasource.driver-class-name=com.mysql.jdbc.Driver修改为如下
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
