JSP与JavaMail之4(发送HTML格式邮件)

5.发送HTML格式的邮件
所谓HTML格式,就是超文本格式.你的邮件可以用HTML代码编写,发给对方后,对方收到的将是信息将是超文本,超文本比纯文本好看多了.下以面是在以前例子的基础上修改的程序:
<%@ page contentType="text/html;charset=GB2312" %>
<%request.setCharacterEncoding("gb2312");%>
<%@ page import="java.util.*,javax.mail.*"%>
<%@ page import="javax.mail.internet.*"%>






<%
try{
String tto=request.getParameter("to");
String ttitle=request.getParameter("title");
String tcontent=request.getParameter("content");
Properties props=new Properties();
props.put("mail.smtp.host","127.0.0.1");
props.put("mail.smtp.auth","true");
Session s=Session.getInstance(props);
s.setDebug(true);
MimeMessage message=new MimeMessage(s);
//给消息对象设置发件人/收件人/主题/发信时间
InternetAddress from=new InternetAddress("xxf@cafe.com");
message.setFrom(from);
InternetAddress to=new InternetAddress(tto);
message.setRecipient(Message.RecipientType.TO,to);
message.setSubject(ttitle);
message.setSentDate(new Date());
//给消息对象设置内容
BodyPart mdp=new MimeBodyPart();//新建一个存放信件内容的BodyPart对象
mdp.setContent(tcontent,"text/html;charset=gb2312");//给BodyPart对象设置内容和格式/编码方式
Multipart mm=new MimeMultipart();//新建一个MimeMultipart对象用来存放BodyPart对
//象(事实上可以存放多个)
mm.addBodyPart(mdp);//将BodyPart加入到MimeMultipart对象中(可以加入多个BodyPart)
message.setContent(mm);//把mm作为消息对象的内容
message.saveChanges();
Transport transport=s.getTransport("smtp");
transport.connect("127.0.0.1","xxf","coffee");
transport.sendMessage(message,message.getAllRecipients());
transport.close();
