在Spring-MVC Hibernate中自动装配的依赖项失败

Question

i tried to run an application in spring MVC and Hibernate using Netbeans. The flow is that i'm passing an ajax request to the controller and i'm getting the response to jsp page without adding @Autowired and Dao(ie, a plain method returning a string from controller). But while adding @Autowired annotation and calling employeeDao i'm getting the below error(ie, unable to autowire) . i have given the right package in the applicationContext.xml(com.demo) and also tried with but still getting the same error. Can anyone please help me. Many Thanks in advance.... `

$.ajax({
    type: 'POST',
    url: "getServices",
    data:  {optionsvalue:optionsvalue},
    success: function(data) {
      $("#idServices").html(data);
    },
    error: function(jqXHR, textStatus, errorThrown) {
        alert("Unable to fetch Services");
    }

});

Here is the EmployeeController.java `

@Controller
public class EmployeeController {
   @Autowired
   EmployeeDao employeeDao;

    @RequestMapping(value = "/getServices", method = RequestMethod.POST)
    public @ResponseBody String getServices(HttpServletRequest request){
        List<ProductServices> pdtServices = employeeDao.getAllServices(request.getParameter("optionsvalue")==null?"":request.getParameter("optionsvalue"));
        StringBuilder strBuilder = new StringBuilder();
    int i=0;
        for(ProductServices ps : pdtServices){
     i++;
         strBuilder.append("<td>");
         strBuilder.append("<input type=\"checkbox\" name=\"chkService"+i+" value="+ps.getServices()+">"+ps.getServices()+"<br>");
         strBuilder.append("</td>");
         strBuilder.append("<td>");
         strBuilder.append("<input class=\"form-control col-xs-1\" name=\"accountNo"+i+" id=\"accountNo\" required=\"true\" placeholder=\"Acc no\" type=\"text\">");
         strBuilder.append("</td>");
         strBuilder.append("<td>");
         strBuilder.append("<input class=\"form-control col-xs-1\" name=\"transactionLimit"+i+" id=\"transactionLimit\" required=\"true\" placeholder=\"Transaction limit\" type=\"text\">");
         strBuilder.append("</td>");
         strBuilder.append("</tr>");
        }
    return strBuilder.toString();
    }
 }

Here is EmployeeDao.java

@Repository("employeeDao")
public class EmployeeDaoImpl implements EmployeeDao{
    @Autowired
    private SessionFactory sessionFactory;
    @Autowired
    private Session session;
    public List<ProductServices> getAllServices(String strProductId){
        session = sessionFactory.getCurrentSession();
        Criteria cr = session.createCriteria(ProductServices.class);
        cr.add(Restrictions.eq("productId", strProductId));
        return (List<ProductServices>) cr.list();
    }

   }

This is applicationContext.xml

Answer 1

Just delete @Autowired from Session object. You get session from session factory.

Answer 2

remove the @Autowired from the Session , and declare it inside of the method

@Repository("employeeDao")
public class EmployeeDaoImpl implements EmployeeDao {
    @Autowired
    private SessionFactory sessionFactory;

    public List<ProductServices> getAllServices(String strProductId) {
        Session session = sessionFactory.getCurrentSession();
        Criteria cr = session.createCriteria(ProductServices.class);
        cr.add(Restrictions.eq("productId", strProductId));
        return (List<ProductServices>) cr.list();
    }

}

Answer 3

change the following code

@Service
public class EmployeeDaoImpl implements EmployeeDao{
    @Autowired
    private SessionFactory sessionFactory;

    @Transactional
    public List<ProductServices> getAllServices(String strProductId){
        Criteria cr = sessionFactory.getCurrentSession().createCriteria(ProductServices.class);
        cr.add(Restrictions.eq("productId", strProductId));
        return (List<ProductServices>) cr.list();
    }

}

This should solve your problem
