使用Springmvc框架实现多文件上传（二）

上一个小demo中，我们使用的是传入数组的方式，接下来我们可以使用单个入参的方式也是可以的

/*//多文件上传
	@RequestMapping(value="/useraddsave.html",method=RequestMethod.POST)
	public String addUserSave(User user,HttpSession session,HttpServletRequest request,
							 @RequestParam(value ="a_idPicPath", required = false) MultipartFile idPicFile,
							 @RequestParam(value ="a_workPicPath", required = false) MultipartFile workPicFile){
		String idPicPath = null;
		String workPicPath = null;
		String path = request.getSession().getServletContext().getRealPath("statics"+File.separator+"uploadfiles"); 
		logger.info("uploadFile path ============== > "+path);
		
		//判断文件是否为空(证件照)
		if(!idPicFile.isEmpty()){
			String oldFileName = idPicFile.getOriginalFilename();//原文件名
			logger.info("uploadFile oldFileName ============== > "+oldFileName);
			String prefix=FilenameUtils.getExtension(oldFileName);//原文件后缀     
	        logger.debug("uploadFile prefix============> " + prefix);
			int filesize = 500000;
			logger.debug("uploadFile size============> " + idPicFile.getSize());
	        if(idPicFile.getSize() >  filesize){//上传大小不得超过 500k
            	request.setAttribute("uploadFileError", " * 上传大小不得超过 500k");
	        	return "useradd";
            }else if(prefix.equalsIgnoreCase("jpg") || prefix.equalsIgnoreCase("png") 
            		|| prefix.equalsIgnoreCase("jpeg") || prefix.equalsIgnoreCase("pneg")){//上传图片格式不正确
            	String fileName = System.currentTimeMillis()+RandomUtils.nextInt(1000000)+"_Personal.jpg";  
                logger.debug("new fileName======== " + idPicFile.getName());
                File targetFile = new File(path, fileName);  
                if(!targetFile.exists()){  
                    targetFile.mkdirs();  
                }  
                //保存  
                try {
