Solve the Problem of inserting data into the longblob field of Mysql

When using mysql, mysql is optimized. The longblob field in mysql is 1 MB by default in mysql 5.5.

To change this issue, pay attention to the following points:

Com. mysql. jdbc. PacketTooBigException: Packet for query is too large (2054817> 1048576). You can change this value on the server by setting the max_allowed_packet 'variable.

Cause: the minimum default configuration of myslq needs to be changed: configure the parameter in mysql. ini (max_allowed_packet = 1024 M );

However, the addition of [client] and [mysql] does not work, and it seems to be a parameter read by the client. So pay attention to this.
