唉，自问自答From the mysql command-line client, logged in as a user that can grant privileges, issue the following command:GRANT ALL PRIVILEGES ON [dbname].* to
'[user]'@'[hostname]' identified by
'[password]'replacing [dbname] with the name of your database, [user] with the user name, [hostname] with the host that MySQL Connector/J will be connecting from, and [password] with the password you want to use. Be aware that RedHat Linux is broken with respect to the hostname portion for the case when you are connecting from localhost. You need to use "localhost.localdomain" for the [hostname] value in this case. Follow this by issuing the "FLUSH PRIVILEGES" command.
