解决方案：

connecturl添加&serverTimezone=UTC

完整的db.properties 如下

jdbc.user=root
jdbc.password=root
#jdbc.driverClass=com.mysql.cj.jdbc.Driver
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/gss?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=UTC
