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:
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
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();
}
}
