这是代码

File saveFile = null;
String tempPath = System.getProperty("java.io.tmpdir");
saveFile = new File(tempPath + File.separator + fileUploadFileName);
FileUtils.copyFile(fileUpload, saveFile);

推荐答案

通过使用Apache commons fileupload FileItem，示例代码将是这样的

By using Apache commons fileupload FileItem, the sample code will be like this

try {
            // parses the request's content to extract file data
            List formItems = upload.parseRequest(request);
            Iterator iter = formItems.iterator();

            // iterates over form's fields
            while (iter.hasNext()) {
                FileItem item = (FileItem) iter.next();
                // processes only fields that are not form fields
                if (!item.isFormField()) {
                    String fileName = new File(item.getName()).getName();
                    String filePath = uploadPath + File.separator + fileName;
                    File storeFile = new File(filePath);

                    // saves the file on disk
                    item.write(storeFile);
                }
            }
            request.setAttribute("message", "Upload has been done successfully!");
        } catch (Exception ex) {
            request.setAttribute("message", "There was an error: " + ex.getMessage());
            ex.printStackTrace();
        }
