Mes BookDAO.class:

@Component 
public class BookDAO { 

    @Bean 
    public BookDAO bookDAO(){ 
     return new BookDAO(); 
    } 

    @Autowired 
    private SessionFactory sessionFactory; 

    private HibernateTemplate hibernateTemplate; 
    @Autowired 
    public void setSessionFactory(SessionFactory sessionFactory){ 
     this.hibernateTemplate = new HibernateTemplate(sessionFactory); 
    } 

    public void save(Book book){ 
     hibernateTemplate.save(book); 
    } 


    public void update(Book book){ 
     book.setModifyTime(new Date()); 
     hibernateTemplate.update(book); 
    } 

    public void delete(Book book){ 
     hibernateTemplate.delete(book); 
    } 

    public List<Book> list(String content, String status, String dprt, String wdz){ 
     Session session = hibernateTemplate.getSessionFactory().getCurrentSession(); 
     Criteria crit = session.createCriteria(Book.class); 
     return list; 

    } 
    public Book getbookById(int id){ 
     return (Book)hibernateTemplate.get(Book.class, id); 
    } 
} 

et mon contrôleur:

@RequestMapping(value="/book.do", method=RequestMethod.GET) 
    @Transactional(rollbackFor=Exception.class) 
    public ModelAndView viewGET(HttpServletRequest request, 
      HttpServletResponse response) throws Exception{ 
     Book book = bookDAO.getbookById(id); 
     modelMap.addAttribute("book", book); 
     return new ModelAndView("book", modelMap); 
    } 

Quand je veux aller sur mon livre.j sp (book.do dans le navigateur) site, je suis exception:

Essayez de changer la configuration de votre filtre:

<filter> 
    <filter-name>hibernateFilter</filter-name> 
    <filter-class> 
     org.springframework.orm.hibernate3.support.OpenSessionInViewFilter 
    </filter-class> 
</filter> 

<filter-mapping> 
    <filter-name>hibernateFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
    <dispatcher>REQUEST</dispatcher> 
    <dispatcher>FORWARD</dispatcher> 
</filter-mapping>
