在动作链中怎么注入service ，现在获取的service是null

public class ApiProProcessor extends AbstractProcessor {

    private static final Log log = Logs.get();
    @Inject
    @Reference
    private HzzyErrorService hzzyErrorService;
    @Override
    public void init(NutConfig config, ActionInfo ai) throws Throwable {
    }

    public void process(ActionContext ac) throws Throwable {
        String uri = Mvcs.getRequestPath(ac.getRequest());
        Hzzy_error hzzyError = new Hzzy_error();
        hzzyError.setErrorContent(ac.getError().getMessage());
        hzzyError.setErrorMehond(uri);
        hzzyError.setErrorParam(ac.getRequest().getParameterMap().toString());
        hzzyError.setErrorType(Hzzy_error.ERRORTYPE_AUTO);
        hzzyError.setVisitIp(Lang.getIP(ac.getRequest()));
        if (hzzyErrorService == null)
            hzzyErrorService = ac.getIoc().get(HzzyErrorService.class,"hzzyErrorService");
        hzzyErrorService.insert(hzzyError);
        doNext(ac);
    }
}
