upload
一.这是action中直接拷过来一段代码,因为一个FORM中还有很多东西,不过都不相关拉。FORM名称就是artMaintForm,UploadFile是在表单中的一个属性
if (artMaintForm.getUploadFile() != null) {
				if (artMaintForm.getUploadFile().getFileName() != null
					&& artMaintForm.getUploadFile().getFileName().trim().length()
						!= 0) {
					//Valid start 验证start
					if (UploadHelper.checkUploadArtFileValid(artMaintForm)) {
						throw new ArtServiceException("error.artService.checkFileTypeValid");
					}
					//Valid end 验证end
					log.debug("-------upload good ======2=====");
					uploadArtFile(artMaintForm);
				}
			}
二.
	private void uploadArtFile(ArtMaintForm artMaintForm) {
		//if (productForm.getArchiveFile() != null) {
		log.info("-------------uploadArtFile  start- 1--");
		if (artMaintForm.getUploadFile() != null) {
			log.info("-------------uploadArtFile  start- 1.1--");
		// afilePath	artFilePath这个两个自己设定的路径	
   String afilePath =
				(String) ConfigFactory.newConfig().getItem(
					ArtConstant.SYSTEMCONFIG,
					A
