springMVC结合AjaxForm上传文件

//执行成功回调函数
function showResponse(e) {
nui.hideMessageBox(msg);
if (e.importFlag == true) {
CloseWindow("ok");
} else {
//对错误的一些处理
}
}

//提交前的一些校验
function showRequest(formData,jqForm,options){
if(formData[0].value=="" || formData[0].value==null){
nui.alert("请选择文件");
return false;
}
var fileName = $("#uploadFile").val().split("\").pop();
var strs = new Array(); //定义一数组
strs = fileName.split('.');
var suffix = strs [strs .length - 1];
if (suffix != 'xls' && suffix != 'xlsx') {
nui.alert("请选择excel文件！");
return false;
}
msg = nui.loading("Loading","Please waiting");
}

importExcel(@RequestParam("file") MultipartFile[] files,HttpServletRequest request) throws Throwable { //long starttiem = System.currentTimeMillis(); InputStream fis; fis = null; File fileIn = null; try { for (MultipartFile myfile : files) { if (!myfile.isEmpty()) { String realPath = request.getSession().getServletContext().getRealPath("/export"); fileIn = new File(realPath); //判断上传文件的保存目录是否存在 if (!fileIn.exists() && !fileIn.isDirectory()) { //创建目录 fileIn.mkdirs(路径); } //将上传的文件复制到文件夹下 myfile.transferTo(new File(路径+文件名)); } } }
