三、解决办法
解决办法有两种
3.1 解决办法一
修改数据连接url
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8修改为：
spring.datasource.url=jdbc:mysql://localhost:3306/test?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-83.2 解决办法二
查看mysql的时区配置show variables like'%time_zone';
mysql默认的时区值是美国，中国的时区要比美国晚8小时，需要采用+8:00的格式。
我们登录mysql，查看当前的时区值，发现时区值是system
修改mysql的配置文件
搜索[mysqld]，在[mysql]节点下加上这一行
default-time-zone='+08:00'重启mysql服务
