Java EasyExcel 导入代码

导入方法

/*** 仓库库位导入** @param req* @param res* @param files* @throws Exception*/@RequestMapping(value = {"/import/line_store_locs"}, method = {RequestMethod.POST})@ResponseBodypublic void importStoreLoc(HttpServletRequest req, HttpServletResponse res, @RequestParam("file") MultipartFile[] files) throws Exception {//获取文件流List<LineStoreLocMode> tempList = new ArrayList<>();if (files != null && files.length != 0) {//获取文件流EasyExcel.read(files[0].getInputStream(), LineStoreLocMode.class, new PageReadListener<LineStoreLocMode>(dataList -> {for (LineStoreLocMode demoData : dataList) {tempList.add(demoData);}})).sheet().doRead();}if (ValueUtil.isEmpty(tempList)) {return;}// 仓库Query query = new Query();List<LineStore> lineStoreList = this.selectList("line_stores", query, LineStore.class);// 型号尺寸List<ModelSize> modelSizeList = this.selectList("model_sizes", query, ModelSize.class);List<LineStoreLoc> locList = new ArrayList<>();for(LineStoreLocMode vo : tempList){List<String> modelList = new ArrayList<>();if(vo.getModelSizeStr().contains("、")){String[] modelSizeArr = vo.getModelSizeStr().split("、");modelList = Arrays.asList(modelSizeArr);}else {modelList.add(vo.getModelSizeStr());}for(String modelName : modelList){LineStoreLoc lineStoreLoc = new LineStoreLoc();LineStore lineStore  = lineStoreList.stream().filter(e -> vo.getStoreName().equals(e.getName())).collect(Collectors.toList()).get(0);lineStoreLoc.setLineStoreId(lineStore.getId());   // 仓库lineStoreLoc.setSegment2Id(vo.getSegment2Id());   // 库区编码lineStoreLoc.setSegment3Id(vo.getSegment3Id());   // 库区名称lineStoreLoc.setName(vo.getName());     // 库位编码lineStoreLoc.setDescription(vo.getDescription());       // 库位名称lineStoreLoc.setProdSubcatName(vo.getProdSubcatName());  // 产品小分类lineStoreLoc.setWarehouseCapcity(vo.getWarehouseCapcity());     // 仓库容量lineStoreLoc.setCapcityUnit(vo.getCapcityUnit());    // 容量单位lineStoreLoc.setSegment1Id(vo.getSegment1Id());     // 备注ModelSize modelSize = modelSizeList.stream().filter(e -> modelName.equals(e.getName())).collect(Collectors.toList()).get(0);lineStoreLoc.setModelSizeId(modelSize.getId());   // 型号尺寸locList.add(lineStoreLoc);}}// 数据插入insertData(locList);}

50条插入一次的方法

private void insertData(List<LineStoreLoc> matCrList){// 每次只插入100条数据List<LineStoreLoc> insertInfoList = new ArrayList<>();int i = 0;for(LineStoreLoc vo : matCrList){insertInfoList.add(vo);i++;if(i >= 50){this.insertBatch(insertInfoList);i = 0;insertInfoList.clear();}}// 剩余条数全部保存this.insertBatch(insertInfoList);}
