Answer 1

可以尝试一下jdbc:mysql://localhost:3306/database?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false即最后设置时区：serverTimezone=GMTGMT%2B8（gmt+8时区）

Answer 2

控制台打印出了你报错的原因是因为你sql的问题：那么应该从这个方向去解决1.是不是只有这一条SQL的执行出现了问题，如果是那么根据报错的原因可能是你时间转换的时候，转换成了sql不识别的时间格式，所以时间格式对不上导致的报错，解决方向：百度Mysql/Oracle数据库时间查询语句2.如果不是这条语句的问题那么应该是在你application的配置中关于时区或者时间相关的配置点出了错，那么你解决方向为：Spring Boot时区格式设置/spring boot时间sql查询之类的
