My dispatcher

Code:

</beans>

Controller

Code:

package controller;

import orm.Utente;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;

import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.servlet.ModelAndView;

import dao.UtenteDAO;

@Controller
public class addUserController {

	@RequestMapping(value="addUser", method = RequestMethod.POST)
	public String createUser (@ModelAttribute("utente") Utente utente, BindingResult result) {
		
		System.out.println("Email " + utente.getEmail() + " registrata!");
//		ApplicationContext ctx =  new ClassPathXmlApplicationContext("beans.xml");
//		UtenteDAO dao = (UtenteDAO) ctx.getBean("utenteDao");
//		dao.insertUtente(utente);
		
		return "User registered!";
	}
}

And the class Utente

	@Override

	@Override

		return this.email.hashCode() + this.password.hashCode();
	}
	
	@Override

		return email+","+password+","+nome+","+cognome+","+spazioDropbox.getSpazio_totale()+","+spazioDropbox.getSpazio_utilizzato();
	}
}

The class Utente is annotated with Hibernate and it works. Sorry for my english!
