- 具体上传服务器例子：

- if (!isMultipart) {

- return;
- }
- DiskFileItemFactory dff = new DiskFileItemFactory();
- try {
- ServletFileUpload sfu = new ServletFileUpload(dff);

- while (iterator.hasNext()) {
- fileStream = iterator.next();
- if (!fileStream.isFormField())
- break;
- fileStream = null;

- if (fileStream == null) {
- return new BaseState(false, 7);
- }
- String savePath ="保存服务器路径";
- String originFileName = fileStream.getName();
