Getting data through an SSH tunnel using Hibernate

问题:

I recently started to learn Hibernate technology and have to get data from a database using Hibernate. The problem is that I can connect to the database only via an SSH tunnel. Are there any properties which I can use in the hibernate.cfg.xml file to solve this problem? Or may be you can suggest another way which will be understandable to a newbie.

Maybe using Jsch. Some examples could give you a way to go.

Another way could be implementing your own SSH SocketFactory, maybe with http proxy handler and port forwarding stuff. A starting point could be:

SSHSocketFactory fact = new SSHSocketFactory(sshHost, sshPort, new SSHPasswordAuthenticator(sshUser, sshPassword));

sock = fact.createSocket(host, port);

And you could link your implementation with the following parameter inside your hibernate.cfg.xml file:

hibernate.connection.socketFactory=com.mysql.jdbc.NamedPipeSocketFactory

Or maybe like the way they do here or here (the latter is the better way to go).

Good ssh stuff!
