Caused by: com.mysql.cj.jdbc.exceptions.PacketTooBigException: Packet for query is too large (5,922,670 > 4,194,304). You can change this value on the server by setting the 'max_allowed_packet' variable.
?这是longblob和blob字段类型的数据默认大小的问题.
命令:
show variables like '%max_allowed_packet%';
?修改下默认大小,改为12M,命令:
set global max_allowed_packet = 12*1024*1024;最后重启mysql
net stop mysql;
net start mysql;=========================================================================
