如何处理max_allowed_packet参数错误的情况？

问题描述：max_allowed_packet参数错误。 错误信息如下所示。 Packet for query is too large (70 > -1). You can change this value on the server by setting the max_allowed_packet’ variable. - com.mysql.jdbc.PacketTooBigException: Packet for query is too large (70 > -1). You can change this value on the server by setting the max_allowed_packet’ variable. 排查思路： max_allowed_packet参数用来控制其通信缓冲区的最大长度，MySQL根据配置文件会限制server接受的数据包大小。有时数据包过大的插入和更新会被max_allowed_packet参数限制，导致失败。 通常设置max_allowed_packet参数的值为10m=10_1024_1024，建议参数值不要设置过大。
