So, I am pretty new to Spring MVC, and I think I'm having problems with configuration and I'm going crazy.
I've tried the solution here but either I'm unable to make it work or my mistake is something different
The error I'm getting is:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'servicioPersonalUrgenciasImplementacion': Unsatisfied dependency expressed through field 'dao'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.modelo.dao.PersonalUrgenciasDAO' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
My components are: Controller. in com.controladores package
@Controller
public class LoginController {
private ServicioPersonalUrgenciasLogin service;
@Autowired
public void setServicioPersonalUrgenciasLogin( ServicioPersonalUrgenciasLogin service) {
this.service = service;
}
@GetMapping("login")
public String login(Model model) {
PersonalUrgenciasLogin login = new PersonalUrgenciasLogin();
//Add customers to the model
model.addAttribute("login", login);
return "login";
}
...
}
Service interface and Service implementation, both in com.modelo.servicios
@Service
public interface ServicioPersonalUrgenciasLogin {
public boolean login(String username, String pwd) throws NoSuchAlgorithmException, UnsupportedEncodingException;
public void cambiarContrasenia(String username, String newpwd);
}
@Service
public class ServicioPersonalUrgenciasLoginImplementacion implements ServicioPersonalUrgenciasLogin {
@Autowired
private PersonalUrgenciasLoginDAO dao;
@Override
@Transactional
public boolean login(String username, String pwd) throws NoSuchAlgorithmException, UnsupportedEncodingException {
return dao.login(username, pwd);
}
@Override
@Transactional
public void cambiarContrasenia(String username, String newpwd) {
// I have to implement this,
}
}
DAO Interface and Implementation, both in com.modelo.dao package
I know this is not the way to implement a login, but I wanted something fast
public interface PersonalUrgenciasLoginDAO {
public boolean login(String username, String pwd) throws NoSuchAlgorithmException, UnsupportedEncodingException;
public void cambiarContrasenia(String username, String newpwd);
}
@Repository
public class PersonalUrgenciasLoginDAOImplementacion implements PersonalUrgenciasLoginDAO{
@Autowired
private SessionFactory factoria;
@Override
public boolean login(String username, String pwd) throws NoSuchAlgorithmException, UnsupportedEncodingException {
Session sesion = factoria.getCurrentSession();
MessageDigest md5 = MessageDigest.getInstance("MD5");
byte[] hashInOne = md5.digest(pwd.getBytes("UTF-8"));
String hashMD5String = getString(hashInOne);
Query<String> query2 = sesion.createQuery(
"SELECT usuario FROM PersonalUrgencias WHERE contrasenia=: pwd AND usuario =:user", String.class);
query2.setParameter("user", username);
query2.setParameter("pwd", hashMD5String);
List<String> haLogueado = query2.getResultList();
return !haLogueado.isEmpty();
}
@Override
public void cambiarContrasenia(String username, String newpwd) {
// TODO Auto-generated method stub
}
private static String getString( byte[] bytes )
{
StringBuffer sb = new StringBuffer();
for( int i=0; i<bytes.length; i++ )
{
byte b = bytes[ i ];
String hex = Integer.toHexString((int) 0x00FF & b);
if (hex.length() == 1)
{
sb.append("0");
}
sb.append( hex );
}
return sb.toString();
}
My Entity. I know it is not wired, but I don't want it to be
And then, my web.xml
<?xml version="1.0" encoding="UTF-8"?>

And this is my applicationContext.xml
I've tried just writting com in <context:component-scan...> too

I'm both grateful and sorry for anybody who has read through all of this
