jspsmart文件上传与邮件发送的实例,需要的朋友可以参考一下
1、jspsmart文件上传(普通表单,带有普通表单域、若干个文件选择域)
页面: 复制代码 代码如下: <form class="form-horizontal" id=“estForm” action="/tools/toolServlet?type=est" method="post" enctype="multipart/form-data"> <div class="control-group"> <label class="control-label" for="email">Email</label> <div class="controls"> <input type="text" id="email" name="email" placeholder="Email" onblur="checkEmail()"> <span class="help-inline"></span> </div> </div> <div class="control-group"> <label class="control-label" for="file">File</label> <div class="controls"> <input type="file" name="file" id="file" onchange="getFileInfo()"/> <span class="help-inline"></span> </div> </div>
<!-- 隐藏文件域 begin <div class="control-group" id="hiddenFileDiv" style="display: none;"> <label class="control-label" for="file">File</label> <div class="controls"> <input type="file" name="file1" id="file1" /> <span class="help-inline"></span> </div> </div>--> <!-- 隐藏文件域 end
<div class="control-group"> <label class="control-label" for="file">crossmatch</label> <div class="controls"> <select name="crossmatch" id="crossmatch"> <option value="Y">Y</option> <option value="N">N</option> </select> <span class="help-inline"></span> </div> </div>--> <div class="control-group"> <div class="controls"> <!-- <a href="javascript:void(0);" id="upload" class="btn">submit</a>--> <button type="submit" class="btn" id="upload">submit</button> <button type="reset" class="btn" id="reset">reset</button> </div> </div> </form>
处理类: 复制代码 代码如下: /** * 文件上传 * @param req * @param resp * @throws ServletException * @throws IOException */ protected void doUpload(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { boolean flag = true; String email = ""; String dataId = String.valueOf(new Date().getTime()); //生成dataId目录 String newPath = estPath + "/" + dataId; createDir(newPath); //生成data目录 newPath = estPath + "/" + dataId + "/data"; createDir(newPath); //生成data目录 newPath = estPath + "/" + dataId + "/result"; createDir(newPath); try{ DiskFileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); upload.setHeaderEncoding("UTF-8"); List<FileItem> list = upload.parseRequest(req); for(FileItem item : list){ if(!(item.isFormField())){ System.err.println("item name:" + item.getName()); if((item!=null)&&(item.getName()!=null)&&(!(item.getName().equals("")))){ String uploadFilename = item.getName(); //处理文件上传 InputStream in = item.getInputStream(); int len = 0; byte[] b = new byte[1024]; newPath = estPath + "/" + dataId + "/data/"; FileOutputStream out = new FileOutputStream(newPath + uploadFilename); while((len=in.read(b))>0){ out.write(b, 0, len); } in.close(); out.close(); item.delete(); //删除item对应的临时文件 } }else{ String fValue = item.getString(); if(fValue.indexOf("@")!=-1){ //邮箱 email = fValue; System.err.println("email:" + email); } } } }catch (Exception e) { flag = false; System.err.println("文件上传失败!" + e); } } req.setAttribute("flag", flag); req.getRequestDispatcher("/view/est.jsp").forward(req, resp); }
2、邮件发送: 复制代码 代码如下: public class EmailAttachService { private static String host = "smtp.163.com"; private static String username = ""; private static String password = ""; private static String mailSubject = ""; public static Vector vfile = new Vector(); //添加附件 public static void addAttachemnt(String fPath){ vfile.add(fPath); } //发送邮件 public static void sendMail(String emailTo,String msg) { // vfile 附件文件集合 try { Properties props = new Properties();// 获取系统环境 Authenticator auth = new EmailAuthenticator(username, password);// 进行邮件服务用户认证 props.put("mail.smtp.host", host); props.put("mail.smtp.auth", "true");
Session session = Session.getDefaultInstance(props, auth); // 设置session,和邮件服务器进行通讯 MimeMessage message = new MimeMessage(session); // 设置邮件发送者的地址 message.setFrom(new InternetAddress(username)); // 设置邮件接收的地址 message.addRecipient(Message.RecipientType.TO, new InternetAddress(emailTo)); // 设置邮件主题 message.setSubject(mailSubject); // 构造Multipart Multipart mp = new MimeMultipart(); // 向Multipart添加正文 MimeBodyPart content = new MimeBodyPart(); content.setContent(msg, "text/html;charset=gb2312"); mp.addBodyPart(content); // 向Multipart添加附件 Enumeration efile = vfile.elements(); while(efile.hasMoreElements()){ MimeBodyPart fattach = new MimeBodyPart(); String fName = efile.nextElement().toString(); FileDataSource fds = new FileDataSource(fName); fattach.setDataHandler(new DataHandler(fds)); fattach.setFileName(MimeUtility.encodeWord(fds.getName(), "GB2312",null)); mp.addBodyPart(fattach); } vfile.removeAllElements(); message.setContent(mp); // 设置邮件发送时期 message.setSentDate(new Date()); message.saveChanges(); //发送邮件 Transport.send(message); } catch (Exception e) { e.printStackTrace(); } }
