JAVA导入表格功能总结

表格结构：

SheetName：sheet名称（辅材采购申请单）

RowNum：行数

FirstCellNum/LastCellNum：第一竖列/最后一竖列（从0开始），例：getCell(0) = 辅材编号

前台到后台上传操作：

HTML：

<!-- 导入文件弹层  -->
<div id="assetUploadDialog" class="pop" style="visibility: hidden;">
    <form id="assetUploadForm" method="post" enctype="multipart/form-data">
        <br/>
        &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input  type="file" name="assetUpload" />
        <font color="red">请按照模板导入辅材*</font>
        <br/>
    </form>
</div>

js：

//上传文件
function assetUploadFile(){
    MaskUtil.mask('正在导入，请等待...');
    var url= context_path + '/auxiliary/auxiliaryImport.do';
    $('#assetUploadForm').form('submit',{
        url:url,
        success:function(ret){
            var r =  JSON.parse(ret);
            $.messager.alert('消息',r.msg);
            if(r.result){
                $('#assetUploadDialog').dialog('close');
                loadDataGrid();//重新获取数据加载页面
                MaskUtil.unmask();
            }else{
                MaskUtil.unmask();
            }
        }
    });
}

Action：

private File assetUpload; // 配置文件上传

 public File getAssetUpload() {
    return assetUpload;
 }

 public void setAssetUpload(File assetUpload) {
    this.assetUpload = assetUpload;
 }
