@Data
@Accessors(chain = true)
public class GetChangeBillList extends ReBase{

    private ChangeBillListData data;

    @Data
    @Accessors(chain = true)
    public static class ChangeBillListData{
        @ApiModelProperty(value = "组合件名称")
        private String zhjName;

        @ApiModelProperty(value = "清单列表")
        private List<BillListItem> billList;

    }
}
