发送HTML类型的电子邮件：
1.在前端输入页面要在上个的基础上加入对邮件类型的判断

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>JavaMail2.html</title>

</head>

<body>

From:<input type="text" name="from"><br>

TO:<input type="text" name="to"><br>

Subject:<input type="text" name="subject"><br>

type:<select name="type" size="1">

</select><br>

Context:<textarea rows="3" cols="40" name="context"></textarea><br>

</form>

</body>

</html>

2.编写servlet : SEND2.java

package com.servlet;

import java.io.IOException;

import java.io.PrintWriter;

import java.util.Date;

import java.util.Properties;

import javax.mail.Message;

import javax.mail.Multipart;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeBodyPart;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMultipart;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class SEND2 extends HttpServlet ...{

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException ...{

response.setContentType("text/html");

PrintWriter out = response.getWriter();

request.setCharacterEncoding("gb2312");

String from = request.getParameter("from");

String to = request.getParameter("to");

String subject = request.getParameter("subject");

String context = request.getParameter("context");

String type=request.getParameter("type");

// 确定要发送的邮件服务器的地址

String mailserver = "codedestiny-pc";

try ...{

// 设置邮件的传输协议

Properties prop = System.getProperties();

prop.put("mail.smtp.host", mailserver);

// 建立邮件发送的连接

Session session = Session.getDefaultInstance(prop, null);

// 创建发送的信息的载体

Message msg = new MimeMessage(session);

// 设置相关的邮件属性

msg.setFrom(new InternetAddress(from));

// 点到点的发送

msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to));

/**//*

* 群发 msg.setRecipients(Message.RecipientType.TO, new

* InternetAddress[]{new InternetAddress(to),new

* InternetAddress(to)}); //借助循环的标准发送

msg.setSubject(subject);

msg.setSentDate(new Date());

//判断发送的Mime类型

Multipart mp = new MimeMultipart();

MimeBodyPart mbp = new MimeBodyPart();

//设置邮件发送数据的类型

mbp.setContent(context, type+";charset=GB18030");

//text/plain或text/html;charset=GB18030,将发送的数据进行封装

mp.addBodyPart(mbp);

msg.setContent(mp);

// 发送

Transport.send(msg);

} catch (Exception e) ...{

e.printStackTrace();

}

out.print("send ok");

out.flush();

out.close();

}
