一次性上传多个文件到服务器端（一）

页面代码：

<form name="form1" action="uploadFileJunior.html" method="post" ENCTYPE="multipart/form-data">
    <input id="File1" name="fileupload" accept="file/*.*" multiple="multiple" type="file" value="" />
    <input id="" type="submit" value="上传" />
</form>

上面实现多选的关键是multiple="multiple"一句。

后台处理代码：

    @RequestMapping("/uploadFileJunior")
    public String uploadFileJunior(@RequestParam("fileupload") MultipartFile[] files,HttpServletRequest request,HttpServletResponse response){
        try {

            int count=files.length;

            for(int i=0;i<count;i++){
                MultipartFile file=files[i];

                InputStream is=file.getInputStream();
                String fileName=file.getOriginalFilename();
                System.out.println("File"+(i+1)+":"+fileName);
                String newFilepath=fileService.upload2Server(is,fileName);
                logger.info(i+":"+file.getOriginalFilename()+" "+" newFilepath="+newFilepath);

            }

            return "/pages/sample/index.jsp";
        } catch (Exception e) {
            e.printStackTrace();
            logger.error(e);

            request.setAttribute("error", e.getClass());
            request.setAttribute("reason", e.getMessage());
            StackTraceElement[] arr=e.getStackTrace();
            request.setAttribute("stackTraceElements", arr);

            return "pages/error/index.jsp";
        }
    }

注意好上面两个fileupload的映射关系，后台这边对应的变量数组是files，之后针对files进行处理就行了。
