解决方法
连接的mysql是8.0.18版本，首先更新mysql驱动到对应版本
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.18</version>
</dependency>
原先的url
jdbc:mysql://localhost:3306/demo?useUnicode=true&;characterEncoding=UTF-8&;serverTimezone=Asia/Shanghai
修改后的url
jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
