Spring PropertyReferenceException:无属性

几天来，我一直在尝试创建SpringCRUD应用程序。我很困惑。我不能解决这个错误

这是相关文件

型号：- 状态

    @ManyToOne
    @JoinColumn(name = "COUNTRY_CODE")
    private Country country;
}

@Service
public interface UtilityService {

    public HashMap<String,String> getListOfCountries();
    public HashMap<String,String> getStateListForSelectedCountry(String countryCode);
}

    @OneToMany(mappedBy = "country")
    private List<State> stateList;

实用服务impl

@Service

    @Autowired

    @Autowired

        Map<String,String> mapOfStates = new HashMap<>();
        List<State> listOfStates = stateRepository.findAllByCountryCode(countryCode);
        listOfStates.forEach(ele ->{
            mapOfStates.put(ele.getStateCode(),ele.getStateName());
        });

        return (HashMap)mapOfStates;
    }

@服务

List listOfStates=stateRepository.findAllByCountryCode（countryCode）；
forEach的状态列表（ele->{

});
返回（HashMap）状态映射；
}

但是我得到了以下错误：-
