spring hibernate jpa: class not found

Я пытаюсь реализовать слой dao с использованием hibernate jpa, но каким-то образом я получаю ClassNotFoundException для своего собственного класса, который, несомненно, расположен в указанном месте. объявления: JPA даосские: конфигурацияspring hibernate jpa: class not found

package com.foo.testapp.daoImpl 
@Repository 
public class JNewsDaoImpl implements NewsDao{ 

    @PersistenceContext() 
    private EntityManager eManager; 
    @Resource 
    UserTransaction uTransaction; 
    @Override 
    public List<News> listNews(boolean isrus) throws DAOTechnicException, 
      DAOLogicException { 
     System.out.println("in jpa"); 
     CriteriaBuilder cb = eManager.getCriteriaBuilder(); 
     CriteriaQuery<News> cQuery = cb.createQuery(News.class); 
     Root<News> rootEntry = cQuery.from(News.class); 
     CriteriaQuery<News> all = cQuery.select(rootEntry); 
     TypedQuery<News> allQuery = eManager.createQuery(all); 
     return allQuery.getResultList(); 
    } 
     //etc 
     } 

package com.foo.testapp.service 
@Service("newsService") 
public class NewsServiceImpl implements NewsService { 
    @Autowired 
    private NewsDao dao; 

    public void setNewsDao(NewsDao newsDao) { 
     this.dao = newsDao; 
    } 
    public void getNewsDao(NewsDao newsDao){ 
     this.dao = newsDao; 
    } 


    @Override 
    @Transactional

     //NewsDaoImpl dao = new NewsDaoImpl(); 
     List<News> listNews = new ArrayList<News>();

Имена пакетов конфигурации XML не соответствуют фактическим.

В XML у вас есть com.epam..., в то время как в источниках Java у вас есть com.foo....

EDIT:

Пожалуйста, проверьте, если у вас есть какие-либо другие исключения заранее. Похоже, вы создаете бобы, используя аннотации - @Repository - и конфигурацию Spring Spring.

нет одинаковых имен на самом деле, я покрыл имена пакетов с помощью foo, просто под вопросом – DeadKennedy

проверю отредактированный ответ, пожалуйста, –

да, спасибо, это помогло – DeadKennedy
