解决:原因是因为我把idxxx输入数据库,但是user表的设计id的字符类型是int,才11位。后来改成了varchar,报错解决。
com.mysql.jdbc.PacketTooBigException: Packet for query is too large (11277826 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable
解决:场景:当向mysql数据库中插入数据大于1m的数据时,提示该异常原因:mysql插入数据的最大允许默认值为1048576(1M)这个值得系统参数:max_allowed_packet查询方法:show VARIABLES like '%max_allowed_packet%'; 解决方法:1.在MySQL安装目录下的my.ini文件中的[mysqld]段中的找到"max_allowed_packet = 1M",修改为自己想要的值(如果没有这行内容,自己添加上去),保存,重起MySQL服务。现在可以load大于1M的文件了。2.使用命令“SET GLOBAL max_allowed_packet=32*1024*1024”或:set @@max_allowed_packet=8*1024*1024
