JavaMail应用实例说明：模板邮件
首先在你的class或src下面建一个properties文件，我新建了一个内容如下：
emailTemplate = <html> <BODY><h2>Hi\uff0c</h2><b> {0} </b><br/>\u4f60\u7684\u7528\u6237\u540d\u4e3a\uff1a{1}\uff0c\u5bc6\u7801\u662f\uff1a{2}\u6b22\u8fce\u8bbf\u95ee\uff1a<a href="http://zmx.iteye.com">\u6211\u7684IT\u6280\u672f\u6742\u8c08</a></BODY></HTML>
原文是：Hi，{0}你的用户名为：{1}，密码是：{2} 欢迎访问：我的IT技术杂谈
注册页面如下：
<form action="SendTemplate"> <table align="center"> <tr> <td align="center">用户名：</td> <td> <input type="text" name="uname"> </td> </tr> <tr> <td align="center">Email：</td> <td> <input type="text" name="uemail"> </td> </tr> <tr> <td align="center" colspan="2"> <input type="submit" value="注册"> </td> </tr> </table> </form>
注册的servlet如下：
public class SendTemplate extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = -7597646570845508429L;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("GBK");
// 获得邮件模板信息
ResourceBundle mailTemplateRb = ResourceBundle.getBundle("emailTemplate");
// 由管理员发送
String from = "[email protected]";
// 注册的用户邮箱
String to = request.getParameter("uemail");
// 设置主题
String subject = "欢迎来到http://zmx.iteye.com";
// 注册用户的用户名
String uname = request.getParameter("uname");
// 注册用户的密码
String upassword = "123456";
// 服务器地址
String mailServer = "PC200904071715";
// 模板参数
Object[] args = new Object[] { uname, uname, upassword };
MessageFormat formater = new MessageFormat("");
formater.applyPattern(mailTemplateRb.getString("emailTemplate"));
String messageText = formater.format(args);
// 设置邮件的传输协议信息
Properties transProp = System.getProperties();
// 邮件服务器地址
transProp.put("mail.smtp.host", mailServer);
// 邮件传输协议中的接收协议：smtp
transProp.put("mail.transport.protocol", "smtp");
// 是否通过验证
transProp.put("mail.smtp.auth", "true");
// 服务器端口
transProp.put("mail.smtp.port", "25");// 默认端口25
Session mailSession = Session.getDefaultInstance(transProp,new Authenticator(){
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("admin","");
}
});
Message mailMessage = new MimeMessage(mailSession);
try {
mailMessage.setFrom(new InternetAddress(from));
mailMessage.setRecipient(RecipientType.TO, new InternetAddress(to));
mailMessage.setSubject(subject);
mailMessage.setSentDate(new Date());
Multipart mp = new MimeMultipart();
MimeBodyPart mbp = new MimeBodyPart();
mbp.setContent(messageText, "text/html;charset=GB2312");
mp.addBodyPart(mbp);
mailMessage.setContent(mp);
Transport.send(mailMessage);
} catch (AddressException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
}
response.sendRedirect("ok.jsp");
}
}
