报错信息:
Error updating database. Cause: com.mysql.jdbc.PacketTooBigException: Packet for query is too large (5872 > 1024). You can change this value on the server by setting the max_allowed_packet' variable.
解决办法:
进入MYSQL
输入show variables like '%max_allowed_packet%';
2.修改配置,我这里设置的是20M
在MYSQL里输入set global max_allowed_packet = 2*1024*1024*10;(20M)

注意:Tomcat要重启,mysql不用重启
show variables like '%max_allowed_packet%';
set global max_allowed_packet = 1048576;
修改之后要关闭连接,重新连接mysql,要不然看不到效果
