新しいコントローラが作成された後、Spring MVC、Hibernateで「Autowired依存関係の注入が失敗しました」というメッセージが表示される

Question

私はspring mvcプロジェクトに新しいコントローラを追加し、以下のようにすべての注釈を追加しました...しかし、 「ここ

...私は問題を把握するために混乱しています... 404例外を取得し、コンソールに、私は以下のように例外を取得していますmは私のコントローラである：

@Controller 
@RequestMapping("/escProjectProgStatusController") 
public class ESCProjectProgStatusController { 
    @Autowired 
    ESCProjectProgStatusService escProjectProgStatusService; 
@RequestMapping(value = "/fetchUnitNameDropDown") 
    public @ResponseBody String fetchUnitNameDropDown(HttpServletRequest request){ 
     String strUnitNames = ""; 
     String strProjectId = request.getParameter("projectId")==null?"":request.getParameter("projectId"); 
     try { 
      strUnitNames = escProjectProgStatusService.fetchUnitNameFromProjectId(strProjectId); 
     } catch (Exception e) { 
      //logger.error(e); 
      throw e; 
     } 
     return strUnitNames.toString(); 
    } 
} 

サービスのImpl：

@Service("escProjectProgStatusServices") 
@Transactional 
public class ESCProjectProgStatusServiceImpl implements ESCProjectProgStatusService { 

    @Autowired 
    ESCProjectProgStatusDao escProjectProgStatusDao; 
@Override 
    public String fetchUnitNameFromProjectId(String strProjectId){ 
     JSONArray jsonArr = new JSONArray(); 
     JSONObject jsonObj = null; 
     List<ProjectUnit> listProjectUnit = null; 
     try{ 
      listProjectUnit = (List<ProjectUnit>)escProjectProgStatusDao.fetchUnitNameFromProjectId(strProjectId); 
      if(listProjectUnit!=null){ 
       for(ProjectUnit projectUnit :listProjectUnit){ 
        jsonObj = new JSONObject(); 
        jsonObj.put("unitType", projectUnit.getUnitType()); 
        jsonObj.put("unitName", projectUnit.getUnitName()); 
        jsonArr.add(jsonObj); 
       } 
      } 
     }catch(Exception e){ 
      //logger.error(e); 
     } 
     return jsonArr.toString(); 
    } 
} 

ダオのImpl：

@Repository("escProjectProgStatusDao") 
public class ESCProjectProgStatusDaoImpl implements ESCProjectProgStatusDao { 
    @Autowired 
    private SessionFactory sessionFactory; 
@Override 
    public List<ProjectUnit> fetchUnitNameFromProjectId(String strProjectId){ 
     List<ProjectUnit> listProjectUnit = null; 
     try { 
      Session session = sessionFactory.getCurrentSession(); 
      Criteria criteria = session.createCriteria(ProjectUnit.class); 
      criteria.add(Restrictions.eq("merchantProductID", strProjectId)); 
      listProjectUnit=criteria.list(); 
     }catch(Exception e){ 
      //logger.error(e); 
     } 
     return listProjectUnit; 
    } 
}

誰もがこのproblem..Manyの事前のおかげを取り除くために私を助けてください....

Answer 1

でESCProjectProgStatusServiceImplクラスの文字列パラメータ@Service注釈を削除します。

前：

@Service("escProjectProgStatusServices") 

後：私は、String @Serviceのパラメータが、それでも同じ問題を削除した：

@Service
