java一个大list 分入70一个小list 批量入库

if(listNew.size()>0){
                   logger.info("走批量插入一个大list:"+listNew.size()+"分70一分小list");
                   List< List<InstantQtyEntity>> listMap = new ArrayList<>();
                   int size =70;
                   int arrSize = listNew.size()%size==0?listNew.size()/size:listNew.size()/size+1;//分成几份
                   logger.info("大list:"+listNew.size()+"分{"+size+"}一分小list:分成"+arrSize+"份");
                   for(int i=0;i<arrSize;i++){//---
                       List<InstantQtyEntity> itemList = new ArrayList<>();
                       for(int j=i*size;j<=size*(i+1)-1;j++){//--
                           if(j<=listNew.size()-1){//核--
                               itemList.add(listNew.get(j));
                           }
 
                       }
                       listMap.add(itemList);
                   }
 
                   for(List<InstantQtyEntity> item : listMap){
                       logger.info(item.toString());
                       int a = webApiMapper.insertInstantQtyStocknumList(item);
                       logger.info("取即时alu_kingdee_outbound_request_stocknum;入库：" + (a > 0 ? "成功" : "失败"));
                   }
 
               }

　　解决：
在java代码中将精度设置成统一的，如
new BigDecimal(“10.28”).setScale(5)，
new BigDecimal("(11.2").setScale(5),
new BigDecimal(“12.51”).setScale(5)，
再次测试批量新增，数据正常：
column1 column2
10.28000 xxx
11.20000 yyy
12.51000 zzz
