在ie8如何异步上传文件，springmvc后台使用MultipartFile接收。

直接上代码给你参考

@RequestMapping("upload")
public String upload(HttpServletRequest request, PrintWriter out) throws JSONException {
String realPath = "D:/upload"
+ DateUtil.getCurrenDate();// 上传图片路径dir
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
Map fileMap = multipartRequest.getFileMap();
MultipartFile multipartFile = null;
String fileName = null;
for (Map.Entry set : fileMap.entrySet()) {
// String filekey = set.getKey();// Filedata
multipartFile = set.getValue();// 文件名
}
fileName = this.storeIOc(multipartRequest, multipartFile,realPath);

String fileName = "";
String logImageName = "";
if (file.isEmpty()) {
System.out.println("文件未上传");
} else {
FileHelper.mkdirs(realPath);//如果文件路径不存在，则创建
String _fileName = file.getOriginalFilename();
String suffix = _fileName.substring(_fileName.lastIndexOf("."));
//
logImageName = UUID.randomUUID().toString() + suffix;
fileName = realPath + File.separator + logImageName;
File restore = new File(fileName);
try {
file.transferTo(restore);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
// 返回默认的图片地址
return fileName;
}

可以私聊我~
