想问问 service 太多依赖怎么办？

一个 service 里面依赖了很多 repository，大家是怎么处理的？并且这些都是业务逻辑需要且围绕当前主体进行使用的。比如

@Service
@RequiredArgsConstructor
public class PlanMaterialServiceImpl extends BaseServiceImpl<PlanMaterialRepository,
    PlanMaterial, Long>
    implements PlanMaterialService {

  private final @NonNull MaterialRepository materialRepository;
  private final @NonNull MaterialTypeRepository materialTypeRepository;
  private final @NonNull PlanMaterialRepository planMaterialRepository;
  private final @NonNull ProcurementPlanRepository procurementPlanRepository;
  private final @NonNull MaterialDemandPlanRepository materialPlanRepository;
  private final @NonNull SysDepartmentRepository sysDepartmentRepository;
  private final @NonNull ApprovalRepository approvalRepository;
  private final @NonNull SysUserRepository sysUserRepository;
  private final @NonNull NotificationRepository notificationRepository;
  private final @NonNull NotifyUtil notifyUtil;
  // ......
}
​

这样他就有 10 个 Repository 需要注入了，但是主体确实是 PlanMaterial。。。大家如何处理这种情况的呢？
