解决方案：

根据提示，判断是时区问题，需要对时区进行配置。

在数据库配置文件中URL这一行后面加上：?serverTimezone=UTC

spring.datasource.url=jdbc:mysql:///myDBname?serverTimezone=UTC

如果存在中文乱码，可以加上：?useUnicode=true&characterEncoding=UTF-8  可以组合使用，写法如下：

spring.datasource.url=jdbc:mysql:///myDBname?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
