文书上传
1.var localFilePath = $("#docFile").val(); // docFile为上传控件的ID
2.var fileName = common.getFileName(localFilePath);
common.getFileName = function(path){
if (!path) {
       return "";
    }
    return path.substring(path.lastIndexOf("\")+1);
}
3.将获得的fileName传递给后台
4.docFilePath = FileUtil.saveFile(createDocForm.docFile, "");

public static String saveFile(FormFile formFile, String sub) throws SystemException, IORuntimeException, FileNotFoundException, IOException, SessionTimeoutException {
        if (formFile == null) {
            return null;
        }

        String rootPath = ServletContextUtil.getServletContext().getRealPath("") + "/tmp/" + SessionAccessor.getSessionId() + "/";
        if (!ValidateUtil.isEmpty(sub)) {
            rootPath += sub + "/";
        }
        rootPath = rootPath.replace("\", "/");
       
        File folder = new File(rootPath);
        String errMsg = MessageUtil.getMessage("ACDC025");
        if (!folder.exists()) {
            if (!folder.mkdirs()) {
                throw new SystemException(errMsg);
            }
        } else {
            int count = 0;
            while (new File(rootPath + count + "/").exists()) {
                count++;
            }
            folder = new File(rootPath + count + "/");
            if (!folder.mkdirs()) {
                throw new SystemException(errMsg);
            }
        }
       
        // UUIDでファイルを保存する
        String ext = formFile.getFileName().replaceFirst(".*[.]", "");
        String path = rootPath + UUID.randomUUID().toString() + "." + ext;
        InputStreamUtil.copy(formFile.getInputStream(), new FileOutputStream(path));
        return path;
