這是錯誤： 產生的原因：的SessionFactory Hibernate的錯誤（Spring MVC的項目）
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of
type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean
which qualifies as autowire candidate for this dependency. Dependency annotations:
{@org.springframework.beans.factory.annotation.Autowired(required=true)}
這是我persistence-context.xml：
<?xml version="1.0" encoding="UTF-8"?>

這是我DAOImpl (generic)：
/**
* Classe generica com metodos padroes utilizados na camada de persistencia
*
* @param <T>
* @param <ID>
*/
public class DAOImpl<T, ID extends Serializable>{
private transient final Class<T> clazz;
@Autowired
private SessionFactory sessionFactory;
@SuppressWarnings("unchecked")
public DAOImpl() {
this.clazz = (Class<T>) ((ParameterizedType)
getClass().getGenericSuperclass()).getActualTypeArguments()[0];
}
/**
* SessionFactory injection
*
* @param sessionFactory
*/
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
/**
* Recupera a sessao corrente
*
* @return sessao corrente
*/
protected Session getSession() {
return sessionFactory.getCurrentSession();
}
/**
* Utiliza a sessao corrente para criar uma nova instancia de criteria
*
* @return instancia de criteria
*/
protected Criteria createCriteria() {
return getSession().createCriteria(clazz);
}
/**
* Utiliza a sessao corrente para criar uma nova query
*
* @param hql
* @return query
*/
protected Query createQuery(String hql) {
return getSession().createQuery(hql);
}
}
這是我的controller：
@Controller
public class IndexController {
@Autowired
UserService userService;
@RequestMapping(value = "/", method = RequestMethod.GET)
public String index(HttpServletRequest request, HttpServletResponse response) {
return "index";
}
}
請問，如果有人現在如何解決這個問題。 謝謝
你的spring配置文件在哪裏？你應該把TransactionManager放在spring配置文件中。因此，Spring可以使Spring事務處於休眠狀態！ – 2014-10-10 02:02:08
請問您可以添加您的web.xml和servlet-context.xml文件的代碼 – 2014-10-10 05:55:10
這是根本原因異常嗎？你能展示完整的堆棧跟蹤嗎？ – pomkine 2014-10-10 07:41:40
