Here is implementation for my service RessourceServiceImpl

package ma.controle.gestion.service.impl;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import ma.controle.gestion.dao.IRessourceDao;
import ma.controle.gestion.modele.Ressource;


@Transactional
@Service("ressourceService")
public class RessourceServiceImpl implements IRessourceDao {

@Autowired
private IRessourceDao ressourceDao;


@Override
public void addRessource(Ressource ressource) {
    System.out.println("Service Baby");
    ressourceDao.addRessource(ressource);
}


public IRessourceDao getRessourceDao() {
    return ressourceDao;
}


public void setRessourceDao(IRessourceDao ressourceDao) {
    this.ressourceDao = ressourceDao;
}


}

and here is the implementation of my dao RessourceDaoImpl

package ma.controle.gestion.dao.impl;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import ma.controle.gestion.dao.IRessourceDao;
import ma.controle.gestion.modele.Ressource;

@Repository("ressourceDao")
public class RessourceDaoImpl implements IRessourceDao {


@Autowired
private SessionFactory sessionFactory; 

@Override
public void addRessource(Ressource ressource) {
    sessionFactory.getCurrentSession().save(ressource);
}

public SessionFactory getSessionFactory() {
    return sessionFactory;
}

public void setSessionFactory(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}
}

whre exactly is `RessourceBean.java: line 62`? is it `System.out.println(" Nom ==>" + getRessource().getNom() );`? — JohnnyAW, Mar 18 '17 at 12:30
@JohnnyAW Hello thank you for your reply line : 62 its `ressourceService.addRessource(ressource);` In the save method — CHARAFI Saad, Mar 18 '17 at 12:35

I guess your @Autowired resourceService is not being set, since you expect it to be IRessourceService, but you are providing:

@Service("ressourceService")
public class RessourceServiceImpl implements IRessourceDao

so the bean container can't pick it up, change your Autowired annotation to:

@Autowired
private IRessourceDao ressourceService;

it was a error RessourceServiceImpl must implement IRessourceSerivce i changed this line but the error stil appear – CHARAFI Saad Mar 18 '17 at 12:51
same error? Make sure `RessourceServiceImpl`-class is in a package, that is being picked up by Annotation processing. Can you post your application initialization log? Maybe there is some error, showing @Autowired not being set. Btw. update your code in the question – JohnnyAW Mar 18 '17 at 12:55
there is no other problemsRessourceServiceImpl class in in a package and here is log for ContextLoader `Infos: Overriding bean definition for bean 'ressourceDao': replacing [Generic bean: class [ma.controle.gestion...` `Infos: Overriding bean definition for bean 'ressourceService': replacing [Generic bean: class [ma.controle.gestion.service.impl.RessourceServiceImpl]; scope=singleton;...` – CHARAFI Saad Mar 18 '17 at 13:07
