直接上代碼了
前端使用layui框架和js
<div class="layui-form-item parent-menu">
<label class="layui-form-label" style="width: 120px;">選擇數據包文件</label>
<div class="layui-input-block" style="margin-left: 180px;">
<div class="layui-upload">
<button type="button" class="layui-btn layui-btn-normal" id="seleceFile">選擇Excel文件</button>
</div>
</div>
</div>
向後臺發出請求
//文件上傳
upload.render({
elem:'#seleceFile'
,url:'/goods/importTable'//上傳接口
,accept:'file'
,acceptMime:""
,auto:false
,multiple:true
,bindAction:'#importBtn'
,data:{
categoryTypeId:function(){
return $("#categoryType_id").val();
}
}
,done:function(res){
//上傳完畢回調
if(res.code==0){
layer.msg(res.msg);
parent.layer.close(index);
}else{
layer.msg(res.msg);
}
}
,error:function () {
//請求異常回調
}
})
我這邊主要是上傳一個商品的Excel，根據Excel表格格式，取出對應行列中的數據，封成商品對象集合並存儲到數據庫中
@RequestMapping("importTable")
@ResponseBody
public ResultObj importTable(@RequestParam("file")MultipartFile
file,HttpServletRequest request, HttpServletResponse response) {
User user = (User) WebUtils.getSession().getAttribute("user");
Goods goodslist=null;
List<Goods> list=new ArrayList<Goods>();
ReadExcel readExcel= new ReadExcel();
//取出Excel表格中數據並封裝成對象返回
List<Goods> goodsList = readExcel.getGoodsExcelInfo(file);
try {
for(Goods goods : goodsList) {
goodslist = new Goods();
if(goods.getGoodsName()!=null) {goodslist.setGoodsName(goods.getGoodsName());}
if(goods.getGoodsSamllImgUrl()!=null) {goodslist.setGoodsSamllImgUrl(goods.getGoodsSamllImgUrl());}
if(goods.getStock()!=null) {goodslist.setStock(goods.getStock());}
if(goods.getAddPrice()!=null) {goodslist.setAddPrice(goods.getAddPrice());}
if(goods.getMarkerPrice()!=null) { goodslist.setMarkerPrice(goods.getMarkerPrice());}
list.add(goodslist);
}
goodsService.saveBatch(list);
return ResultObj.UPLOAD_SUCCESS;
} catch (Exception e) {
e.printStackTrace();
return ResultObj.UPLOAD_ERROR;
}
}
下面是具體取出Excel表格數據並封裝對象集合返回
