@Autocâblés - Pas de qualification bean de type trouvé pour la dépendance au moins 1 fève

Actuellement, je suis confronté à un problème dans Autowire de configuration entre le contrôleur et la couche de service.

Je suis incapable de faire le suivi de mes erreurs.

Simple Journal Info

    SEVERE:   Exception while loading the app
SEVERE:   Undeployment failed for context /OTT
SEVERE:   Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type [com.ott.service.EmployeeService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

Ci-dessous j'ai également donné le Contrôleur et la Couche de Service code et aussi le dispatcher-servlet.xml

Contrôleur

package com.ott.controller;
import com.ott.service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
*
* @author SPAR
*/
@Controller
public class AdminController {
private EmployeeService employeeService;
@RequestMapping("/employee")
public String employee(){
this.employeeService.fetchAll();
return "employee";
}
@Autowired(required = true)
@Qualifier(value="employeeService")
public void setEmployeeService(EmployeeService empService) {
this.employeeService = empService;
}
}

Interface De Service

package com.ott.service;
import com.ott.hibernate.Employee;
import java.util.List;
/**
*
* @author SPAR
*/
public interface EmployeeService {
List<Employee> fetchAll();
}

Interface De Service Impl

package com.ott.service;
import com.ott.dao.EmployeeDAO;
import com.ott.hibernate.Employee;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
/**
*
* @author SPAR
*/
@Service
public class EmployeeServiceImpl implements EmployeeService{
private EmployeeDAO employeeDAO;
@Override
@Transactional(readOnly = true)
public List<Employee> fetchAll() {
List<Employee> employees = employeeDAO.fetchAll();
for (Employee employee : employees) {
System.out.println("Name : "+employee.getFirst_Name() +" "+ employee.getLast_Name());
System.out.println("Email Id : "+employee.getEmail_Id());
}
return employees;
}
@Autowired(required = true)
@Qualifier(value="employeeDAO")
public void setEmployeeDAO(EmployeeDAO empDAO) {
this.employeeDAO = empDAO;
}
}

pouvez-vous ajouter @Service("employeeService")
