Description:

Field statusUpdateService in spring.controller.pageController required a bean of type 'service.StatusUpdateService' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'service.StatusUpdateService' in your configuration.

это мой pageController:

package spring.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import service.StatusUpdateService;
import spring.model.StatusUpdate;


@Controller
public class pageController {

    @Autowired
    private StatusUpdateService statusUpdateService;

    @RequestMapping("/")
    String home() {
        return "app.homepage";
    }

    @RequestMapping("/about")
    String about() {
        return "app.about";
    }

    @RequestMapping(value = "/addstatus", method = RequestMethod.GET)
    ModelAndView addstatus(ModelAndView modelAndView) {

        modelAndView.setViewName("app.addstatus");

        StatusUpdate statusUpdate = new StatusUpdate();

        StatusUpdate latestStatusUpdate = statusUpdateService.getLatest();


        modelAndView.getModel().put("statusUpdate", statusUpdate);
        modelAndView.getModel().put("latestStatusUpdate", latestStatusUpdate);

        return modelAndView;
    }

    @RequestMapping(value = "/addstatus", method = RequestMethod.POST)
    ModelAndView addstatus(ModelAndView modelAndView, StatusUpdate statusUpdate) {

        modelAndView.setViewName("app.addstatus");

        statusUpdateService.save(statusUpdate);

        StatusUpdate latestStatusUpdate = statusUpdateService.getLatest();
        modelAndView.getModel().put("latestStatusUpdate", latestStatusUpdate);


        return modelAndView;
    }
}

и это мой StatusUpdateService:

пакетный сервис;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import spring.model.StatusUpdate;
import spring.model.StatusUpdateDao;

@Service
public class StatusUpdateService {

  @Autowired
  private StatusUpdateDao statusUpdateDao;

  public void save(StatusUpdate statusUpdate) {
      statusUpdateDao.save(statusUpdate);
  }

  public StatusUpdate getLatest() {
      return statusUpdateDao.findFirstByOrderByAddedDesc();
  }

}

что может быть проблема? спасибо
