但是我尝试启动时仍然遇到相同的错误，我以为我错过了图书馆购买的问题仍然存在，我是否错过了其他图书馆或其他东西？hibernate-core和entity manager的版本为5.0.12都

Answer 1

由以下原因引起：com.mysql.jdbc.MysqlDataTruncation：数据截断：错误的日期时间值：第1行的“ created_at”列为“ 0000-00-00 00:00:00”

在错误详细信息中，您在注释表中为“ created_at”列获取的日期时间值不正确：'0000-00-00 00:00:00'。 您应该在mysql中更改NO_ZERO_DATE sql模式。
