you want to utilize time zone support.

上述环境

druid :1.1.3 , jdbc driver:6.0.6 ,mysql :5.7.16

程序链接数据库属性配置

jdbc.type=mysql

jdbc.driver=com.mysql.cj.jdbc.Driver

jdbc.url=jdbc:mysql://172.16.2.10:3306/dadao?useUnicode=true&characterEncoding=utf-8

后修改成：

jdbc.driver=com.mysql.cj.jdbc.Driver

jdbc.url=jdbc:mysql://172.16.2.10:3306/dadao?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true&serverTimezone=Asia/Shanghai

无此错误。

原因分析：这是由于数据库和系统时区差异所造成的，在jdbc连接的url后面加上serverTimezone，还有就是降低Mysql驱动版本
