發送郵件html

1、MailOperation.java 主要文件，郵件操做，發送

package main;java

import java.util.Date;瀏覽器

import java.util.Properties;安全

import javax.mail.Message;session

import javax.mail.Multipart;app

import javax.mail.Session;測試

import javax.mail.Transport;ui

import javax.mail.internet.InternetAddress;this

import javax.mail.internet.MimeBodyPart;spa

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMultipart;

public class MailOperation {

/**

* @author goming

*TODO:發送郵件

*@param user

*@param password

*@param host

*@param from

*@param to

*@param subject

*@param content

*@return

*@throws Exception

public String sendMail(String user,String password,String host,String from,String to,String subject,String content) throws Exception {

// TODO Auto-generated method stub

if(to!=null)

{

Properties props=System.getProperties();

props.put("mail.smtp.host", host);

props.put("mail.smtp.auth", "true");

MailAuthenticator auth=new MailAuthenticator();

MailAuthenticator.USERNAME=user;

MailAuthenticator.PASSWORD=password;

Session session=Session.getInstance(props,auth);

session.setDebug(true);

try{

MimeMessage message=new MimeMessage(session);

//message.setDataHandler(new DataHandler(content, "text/html; charset=utf-8"));//設置郵件內容

message.setFrom(new InternetAddress(from));

if(!to.trim().equals(""))

message.addRecipient(Message.RecipientType.TO, new InternetAddress(to.trim()));

message.setSubject(subject);

// message.setContent(mp)

//message.setText("this is 一個測試郵件");

MimeBodyPart mbp1=new MimeBodyPart(); //正文

mbp1.setContent(content,"text/html;charset=utf-8");

Multipart mp=new MimeMultipart(); //整個郵件：正文+附件

mp.addBodyPart(mbp1);

//mp.addBodyPart(mbp2);

message.setContent(mp);

message.setSentDate(new Date());

message.saveChanges();

Transport trans=session.getTransport("smtp");

trans.send(message);

System.out.println(message.toString());

}catch(Exception e)

{

e.printStackTrace();

return "failure";

}

return "success";

}

else

return "failure";

}

public static void main(String[] args) {

MailOperation operation = new MailOperation();

String user = "admin@xiamengoldenway.com";

String password = "xmG0ldenway";

String host = "smtp.qq.com";

String from = "admin@qq.com";

String to = "******@qq.com";//收件人

String subject = "Test";

String content = "測試郵件";

try {

String res = operation.sendMail(user, password, host, from, to, subject, content);

System.out.println(res);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

System.out.println(new Date());

}

2、MailAuthenticator.jave 封裝發件人帳號密碼

import javax.mail.Authenticator;

import javax.mail.PasswordAuthentication;

/**

* @author goming

public class MailAuthenticator extends Authenticator

{

public static String USERNAME = "";

public static String PASSWORD = "";

public MailAuthenticator(){}

protected PasswordAuthentication getPasswordAuthentication(){

return new PasswordAuthentication(USERNAME, PASSWORD);

}

3、SendEmail.java 調用類，主要作郵件內容，以及發送一個地址回訪！

/**

* 發送郵件

* @author goming

* @param to

* @param uuid

@RequestMapping(params = "sendMail")

@ResponseBody

private void sendMail(String to,HttpServletRequest request){

MailOperation operation = new MailOperation();

//發件人

String user = "*****@qq.com";

String password = "******";

String host = "smtp.qq.com";

String from = "1915960810@qq.com";

String subject = "感謝您註冊創意生態資源集成系統軟件";

//郵箱內容

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath()+"/";

StringBuffer sb = new StringBuffer();

Date date=new Date();

Long longtimeLong=date.getTime();

sb.append("<!DOCTYPE>"+"<div bgcolor='#f1fcfa' style='border:1px solid #d9f4ee; font-size:12px; line-height:22px; color:#005aa0;padding-left:1px;padding-top:5px; padding-bottom:5px;'><span style='font-weight:bold;'>安全提示：</span>"

+ "<div style='width:950px;font-family:arial;'>爲了您的帳戶安全，咱們建議您點擊如下連接驗證郵箱：<br/><a href='"+basePath+"UserRegister.do?ValidateEmail&time="+longtimeLong+"&token="+to+"'>"+basePath+"UserRegister.do?ValidateEmail&time="+longtimeLong+"&token="+to+"</a><br/>請在24小時內點擊該連接，您也能夠將連接複製到瀏覽器地址欄訪問。<br/>本郵件由系統自動發出，請勿回覆。<br/>感謝您的使用。<br/>廈門交叉媒體科技有限公司</div>"
