spring mvc 下使用ajaxfileupload.js 异步上传文件 并返回信息 各种问题解决

业务需要用ajax异步上传excel文件并回传解析后的错误信息，后台spring mvc, jquery 2.1.3, ajaxfileupload.js

一 页面js代码：

$("#importUserButton").click(function(){    alert("here1");    $.ajaxFileUpload({            url:serverUri+"/user/importuser",            type: "POST",            cache : false,            secureuri:false,            fileElementId:"importUserFile",            dataType: "json",            success : function(data) {                alert(data.success);            },            error : function(data) {                alert("error");            }    });});

二 后台代码：

IE10下返回json串会提示下载，所以ContentType设置为‘text’

@ResponseBody@RequestMapping(value = "/importuser", method = RequestMethod.POST)public Map<String,Object> importUser(HttpServletRequest request, HttpServletResponse response){    response.setContentType("text/html;charset=UTF-8");    MultipartHttpServletRequest mulRequest = (MultipartHttpServletRequest) request;    MultipartFile file = mulRequest.getFile("importUserFile");    String fileName = file.getOriginalFilename();    System.out.println("fileName:"+fileName);    Workbook wb = null;    try {        InputStream in = file.getInputStream();        if (fileName.endsWith(".xls") || fileName.endsWith(".XLS")) {            wb = new HSSFWorkbook(in);        } else if (fileName.endsWith(".xlsx") || fileName.endsWith(".XLSX")) {            wb = new XSSFWorkbook(in);        }        in.close();    } catch (IOException e) {        e.printStackTrace();    }    ..........    ..........    Map<String, Object> map = new HashMap<String, Object>();    map.put("success", "true");    return map;}

三 ajaxfileupload.js 遇到过以下问题：

1.handleError 无法找到

2.上传后只执行error 函数

3.不支持IE(IE 下上传无反应)

附上改后全能的js文件。
