Injection of autowired dependencies failed on web service

Ola,
estou com problema para injetar o objeto HomeIndicadoresReportService no web service

segue Web Service Class

@Service
@WebService(endpointInterface =     "com.santander.portalcio.ws.IndicadoresBSTSWebServiceInterface")
public class IndicadoresBSTSWebServiceImpl extends SpringBeanAutowiringSupport implements     IndicadoresBSTSWebServiceInterface {

@PostConstruct
public void init() {
	SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
}

@Autowired
private HomeIndicadoresReportService homeIndicadoresReportService;


@WebMethod
public ListaWS teste(String abc) {

		homeIndicadoresReportService.buildValuesToGraph(resultMesAtual, selectedEntity, selectedBS, selectedTS,
				selectedFunctionality, filter, false);


	return new ListaWS(resultMesAtual);
}

}

HomeIndicadoresReportService Class:

public interface HomeIndicadoresReportService extends Serializable {

public void selectAndBuildEntityBsTsFunc(List<EntityIndicatorVO> resultAux, BSTSIndicatorsFilterVO filter);

public void selectcompFuncInc(List<EntityIndicatorVO> resultAux, EntityIndicatorVO selectedEntity,
		BSIndicatorVO selectedBS, TSIndicatorVO selectedTS, FunctionalityIndicatorVO selectedFunctionality,
		BSTSIndicatorsFilterVO filter, boolean isIndicatorsBSTS);

public void selectTotaoInc(List<EntityIndicatorVO> resultAux, EntityIndicatorVO selectedEntity,
		BSIndicatorVO selectedBS, TSIndicatorVO selectedTS, FunctionalityIndicatorVO selectedFunctionality, BSTSIndicatorsFilterVO filter);

public void buildValuesToGraph(List<EntityIndicatorVO> resultMes, EntityIndicatorVO selectedEntity,
		BSIndicatorVO selectedBS, TSIndicatorVO selectedTS, FunctionalityIndicatorVO selectedFunctionality,
		BSTSIndicatorsFilterVO filter, boolean isIndicatorsBSTS);

}
