Packet for query is too large (5,145 > 1,024). You can change this value on the server by setting the 'max_allowed_packet' variable.

錯誤

在使用Mybatis generator時提示MySQL寫入過大

Packet for query is too large (5,145 > 1,024). You can change this value on the server by setting the 'max_allowed_packet' variable.

環境

MySQL 8.0.11

Mybatis generator 1.3.7

查詢

SHOW VARIABLES LIKE '%max_allowed_packet%'

修改my.cnf

在my.cnf中添加

max_allowed_packet=10M

重啟mysql

這樣就可以了。
