Galera, boa noite. Estou com um problema na integração do Spring + Struts 2 e não sei o que pode estar havendo. O problema é que o Spring não está injetando os DAOs e cai em NullPointerException. Estou usando o @Resource, mas acho que está faltando alguma configuração em algum lugar… rs rs rs Alguém pode me dar uma luz?
E o problema não é DAO, porque já fiz vários tests e tudo funciona.
@Service("userAccountDAO")
public class UserAccountDAOImpl
extends HibernateDAOServiceImpl<UserAccount, Integer>
implements UserAccountDAO {
@Override
public UserAccount findByName(String userName) {
Criteria criteria = getSession().createCriteria(UserAccount.class);
criteria.add(Restrictions.like("name", userName));
return (UserAccount) criteria.uniqueResult();
}
}Minha action está assim:
public class LoginAction extends ActionSupport implements SessionAware,
ServletRequestAware, ServletResponseAware {
private HttpServletRequest request;
private HttpServletResponse response;
private Map<String, Object> session;
private String userName;
private String userPassword;
@Resource
private UserAccountDAO userAccountDAO;
public LoginAction() {}
public String loginValidate() {
UserAccount userAccount = new UserAccount();
// Quando chamo o DAO na linha abaixo,
// ocorre NullPointerException
List<UserAccount> list = userAccountDAO.findAll();
// Assim também da erro
// UserAccount userAccount = userAccountDAO.findById(new Integer(1));
if (userAccount != null) {
session.put("userAccount", userAccount);
return SUCCESS;
}
return ERROR;
}
// Getters and setters suprimidos
