处理类：

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();
}
}
</div>
