java组织。springframework。豆。工厂UnsatifiedPendencyException:创建名为“ServicePersonalUrgenceAsImplementAcion”的bean时出错

Question

所以，我对SpringMVC还很陌生，我觉得我在配置方面遇到了问题，我快疯了

我已经尝试过这个解决方案，但要么我无法使它工作，要么我的错误是不同的

我得到的错误是：

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)}

我的组件是： 控制器。在com中。Controladors软件包

@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";
    }
...
}

com中的服务接口和服务实现。莫德罗。服务

@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接口和实现，都在com中。莫德罗。dao包

我知道这不是实现登录的方法，但是我想要一些快速的东西

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();
    }

我的实体。我知道它不是有线的，但我不想这样

然后，我的网络。xml
