application Context (spring)

Bonsoir à tous.Je suis débutante en spring.

Je tente actuellement de mettre en place un projet avec Hibernate et Spring.

Dans le répertoire "src" de mon projet, j'ai créé le fichier "application-context.xml" suivant :

Prenons par exemple la classe "Administrateur". J'ai créé une interface que je l'ai implémenté dans la classe "AdministrateurServiceImpl" que voici :

package com.esprit.ProjetPFE.service;
 
import java.util.List;
 
 
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
 
import com.esprit.ProjetPFE.model.Administrateur;
 
@Service("administrateurService")
@Transactional
public class AdministrateurServiceImpl implements AdministrateurService {
 
	@Autowired
	private SessionFactory sessionFactory;
 
	@Override
	@SuppressWarnings("unchecked")
	public List<Administrateur> findAll() {
 
		return sessionFactory.getCurrentSession().createQuery("from Administrateur").list();
	}
 
	@Override
	public Administrateur findById(int id) {
 
		return (Administrateur) sessionFactory.getCurrentSession().load(Administrateur.class, id);
	}
 
	@Override
	public void save(Administrateur administrateur) {
		sessionFactory.getCurrentSession().saveOrUpdate(administrateur);
 
	}
 
}

Afin de tester le bon fonctionnement de tout, j'ai créé un JUnit Test que voici :

public class AdministrateurServiceTest {
 
	private static ClassPathXmlApplicationContext context;
	private static AdministrateurService administrateurService;
 
	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		context=new ClassPathXmlApplicationContext("application-context.xml");
		administrateurService=(AdministrateurService) context.getBean("administrateurService");
	}
 
	@AfterClass
	public static void tearDownAfterClass() throws Exception {
		context.close();
	}
 
	@Test
	public void testFindAll() {
		fail("Not yet implemented");
	}
 
	@Test
	public void testFindById() {
		fail("Not yet implemented");
	}
 
	@Test
	public void testSave() {

}

Mais voilà, j'ai les messages d'erreurs suivants :
