I think that you need to set the following parameters in your connection URL:

jdbc:mysql://host:port/db?useUnicode=true&characterEncoding=UTF-8

with change in my.cnf (mysql configure file) in /etc/mysql (linux) and add this 2 tag solved my problem

default-character-set=utf8
default-collation=utf8_persian_ci
