jspsmart文件上传与邮件发送的实例

  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();

  }

  }
