springmvc上传
??? 最近一直在网上看资料，今天我在网上发现一个demo,是基于springMVC开发的上传。由于本人刚好这两天在学习springMVC。以前用struts2.0 做过多文件上传的，现在我把这springMVC的多文件上传来分享给大家。我是根据http://zhoshijie.iteye.com/blog/1177390给的demo完成的啊，希望原著能支持！！！我来简单讲解一下。

一下这段主要是告诉大家另外一种传参的方式，上面是用request取的： @RequestParam("name") String name, //设置请求参数的名称和类型? @RequestParam("file") CommonsMultipartFile mFile
//??? ?public String handleFormUpload(@RequestParam("name") String name, //设置请求参数的名称和类型
//??? ??? ??? ?? @RequestParam("file") CommonsMultipartFile mFile) { //请求参数一定要与form中的参数名对应
//??? ??? ??? ? if (!mFile.isEmpty()) {
//??? ??? ??? ?? String path = this.servletContext.getRealPath("/tmp/");? //获取本地存储路径
//??? ??? ??? ?? File file = new File(path + new Date().getTime() + ".jpg"); //新建一个文件
//??? ??? ??? ?? try {
//??? ??? ??? ??? mFile.getFileItem().write(file); //将上传的文件写入新建的文件中
//??? ??? ??? ?? } catch (Exception e) {
//??? ??? ??? ??? e.printStackTrace();
//??? ??? ??? ?? }
//??? ??? ??? ? }
