Excel上传示例及后台解析Excel

<form action="../module/AccountInfoBatch-input.action" method="post" id="formId" enctype="multipart/form-data">

       文件：
      <input type="file" name="file1" id="fileId"/>
      <input id="tijiao" type="submit" style="margin-right: 10px; margin-top: 70px;"  class="btn btn-md btn-primary" value="提交"></input>

</form>

<script>

function submitData() {
 onsubmit ="document.getElementById('tijiao').disabled=true;return true;" ;
var fileId = $("#fileId").val();
if (fileId == "") {  
            alert("请选择要上传的文件");  
            return false  ;
        }
         var exec = (/[.]/.exec(fileId)) ? /[^.]+$/.exec(fileId.toLowerCase()) : '';

List<AccountCSVModel> accountCSVModelList = new ArrayList<AccountCSVModel>();
Workbook wb = WorkbookFactory.create(xlsOrxlsxFile);

for (int rowIndex = firstRowNum ; rowIndex <= lastRowNum; rowIndex++) {

if (null != row) {
AccountCSVModel accountCVSModel = new AccountCSVModel();
accountCVSModel.setP2p(getValue(row.getCell(1)));

accountCVSModel.setIdType(getValue(row.getCell(3)));
accountCVSModel.setName(getValue(row.getCell(4)));
accountCVSModel.setBindMobile(getValue(row.getCell(5)));
accountCVSModel.setAcctUse(getValue(row.getCell(6)));
accountCVSModel.setCardNo(getValue(row.getCell(7)));
accountCVSModel.setAccountId(getValue(row.getCell(8)));
accountCVSModel.setOpenDate(getValue(row.getCell(9)));
accountCSVModelList.add(accountCVSModel);
}
}
}
return accountCSVModelList;
}

// 转换数据格式
private static String getValue(Cell xssfRow) {
if (xssfRow.getCellType() == xssfRow.CELL_TYPE_BOOLEAN) {
return String.valueOf(xssfRow.getBooleanCellValue());
} else if (xssfRow.getCellType() == xssfRow.CELL_TYPE_NUMERIC) {
return String.valueOf(xssfRow.getNumericCellValue());
} else {
return String.valueOf(xssfRow.getStringCellValue());
}
}

注意：form表单必须表明：enctype="multipart/form-data"

并且上上传文件只能form表单提交。不能ajax。

ajax实现：待实现
