struts上传文件注意事项
1.导入两个包：commons-fileupload-1.1.1.jar和commons-io-1.1.jar
2.ActionForm类要有FormFile类型的属性
3.JSP页面的form需要有enctype="multipart/form-data"属性，并且必需是strut标签
4.Action类里获取服务器地址例子如下：
DocAddForm d_form = (DocAddForm) form; if (d_form != null) { FormFile file = (FormFile) d_form.getFile(); try { byte[] content1 = file.getFileData(); String path = request.getSession().getServletContext().getRealPath("");// 获取web服务器地址 File file1 = new File(path + "/files/" + file.getFileName()); FileOutputStream out = new FileOutputStream(file1); out.write(content1); out.close(); } catch (Exception e) { e.getStackTrace(); } }
