私はprimefacesスプリングとJSFを使用していると私は私の豆 からメソッドを呼び出すときには、ビューからプロパティを取得しますが、それは私のサービスの方法に到着したときに、DAOを呼び出すことにより、データのデータベースへの挿入を行うこと方法このエラーが表示され、ここで 解決策が必要このエラーを解決する方法？

私はあなたの@Autowired resourceServiceがあなたのために、設定されていないと思います私のサービスRessourceServiceImpl

@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;
}
}
ための実装であり、ここに私の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;

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;
}
}
：ライン62'？それは 'のSystem.out.println（ "ノム==>" + getRessource（）getNom（））;'？ – JohnnyAW
@JohnnyAWご返信いただきありがとうございます：62その 'ressourceService.addRessource（ressource）;'保存メソッド –
