Spring：自動従属依存のインジェクションが失敗しました

Question

何らかの理由により、SpringはRepoをサービスクラスに自動配線できません。私は同様の問題を扱うすべてのSOスレッドを通過しましたが、私は問題を解決できませんでした。

ここは私のコードです。

public interface WProcessItemDetailsRepo extends PagingAndSortingRepository<WProcessItemDetail, Long>, JpaSpecificationExecutor<WProcessItemDetail>{ 

} 

とサービスクラス

@Service("processItemDetailsService") 
@Transactional 
public class WProcessItemDetailsService implements Serializable{ 
    /** 
    * 
    */ 
    private static final long serialVersionUID = 2395733723021028217L; 
    @Autowired 
    WProcessItemDetailsRepo detailsRepo; 

    public WProcessItemDetail save(WProcessItemDetail detail){ 
     return detailsRepo.save(detail); 

    } 
    public List<WProcessItemDetail> save(List<WProcessItemDetail> details){ 
     return (List<WProcessItemDetail>) detailsRepo.save(details); 
    } 

} 

私はプログラムを実行しようとすると、それは私はあなたがあなたのインターフェイスのための注釈を忘れてしまったと思う次のスタックトレース
