Can't connect jdbc with mysql 5.6

Question

When trying to connect from MyBatis and jdbc to mysql 5.6 I get an exception

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: communications link failure

This only happened after upgrading from 5.1 to 5.6.

I looked at the driver official page. the latest available driver is for 5.1.

Answer 1

I encountered this problem too, then I realized I didn't have the WAMP server open. Check if you have opened WampServer (or LampServer if you are using Linux).

Answer 2

The problem was in the configuration in

/etc/my.cnf

it looks like 5.6 doesn't accept all configuration items as 5.1. I had to remove

default-character-set=utf8

to start the mysql-server

and had to remove

bind-address    =   ? 

for to resolve the exception I was getting in my question above. and start tomcat applications.
