springmvc+layui的多文件上传

话不多说直接上代码：

public String uploadFile2(HttpServletRequest request, HttpSession session) throws Exception {
      // 创建一个通用的多部分解析器
      CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(request.getSession().getServletContext());
      JSONObject resObj = new JSONObject();
      if (multipartResolver.isMultipart(request)) {
         // 转换成多部分request
         MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
         // get the parameter names of the multipart files contained in this request
         Iterator iter = multiRequest.getFileNames();
         while (iter.hasNext()) {
            // 取得上传文件
            List multipartFiles = multiRequest.getFiles(iter.next());
//          String dirPath = "E:/Code/ideaCode/educational-admin/src/resources/Files/";
//          String dirPath = "E:/Code/ideaCode/educational-admin/src/resources/Files/";
            String dirPath = "/home/tomcat/apache-tomcat-8.5.42/webapps/educational-1.0-SNAPSHOT/resource/Files/";
            for (MultipartFile multipartFile : multipartFiles) {
               String originalFilename = multipartFile.getOriginalFilename();
               System.out.println("originalFilename------>" + originalFilename);
               if (StringUtils.isNotEmpty(originalFilename)) {
                  multipartFile.transferTo(new File(dirPath + originalFilename));

                  // 获取服务器路径
                  String serverUrl = "";
                  serverUrl = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + "/resource/Files/" + originalFilename;

                  UploadFile uploadFile = new UploadFile();
                  uploadFile.setFileName(originalFilename);
                  uploadFile.setUploadPerson(String.valueOf(session.getAttribute("stu_name")));

                  resObj.put("fileType", fileType);
                  // 进行插入
                  uploadFileService.addUploadFile(uploadFile);
                  DownloadFile df = new DownloadFile();
                  df.setFileName(originalFilename);
                  df.setFile(originalFilename);
                  df.setFileUrl(dirPath);

                  df.setStatus(0);
                  df.setUploadTime(CreateTimeUtils.createTime());

                     // 截取数据
                     if (title.contains("[") || title.contains("]")) {
                        String realTitle = title.substring(title.indexOf("[") + 1, title.indexOf("]"));
                        boolean flag = false;
                        if (realTitle.contains("学生信息导入表")) {
