类已经封装在SDK里面了，无法插入@JsonField，能否指定注解为@ApiField，先不考虑faster json的Serializer

public class WlbWaybillISearchResponse extends TaobaoResponse {
  private static final long serialVersionUID = 4773645678145939655L;
  @ApiListField("subscribtions")
  @ApiField("waybill_apply_subscription_info")
  private List<WaybillApplySubscriptionInfo> subscribtions;

  public WlbWaybillISearchResponse() {
  }

  public void setSubscribtions(List<WaybillApplySubscriptionInfo> subscribtions) {
    this.subscribtions = subscribtions;
  }

  public List<WaybillApplySubscriptionInfo> getSubscribtions() {
    return this.subscribtions;
  }
}

namespace Top.Api.Domain
