报错信息如下：

这个问题我之前在ubuntu上没有遇到，是在Windows上使用时出现了这个问题。
解决办法：
在spring.datasource.url对应的URL后面加?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8
例：
spring.datasource.url=jdbc:mysql://localhost:3306/zifeiydb?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8
完整的一个application.properties例子：
# DB Configurationspring.datasource.driverClassName=com.mysql.cj.jdbc.Driverspring.datasource.url=jdbc:mysql://localhost:3306/zifeiydb?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8spring.datasource.username=rootspring.datasource.password=password# .zifeiy.demo=debug
