Java 邮件发送代码详解编程语言

发送邮件

1、MailOperation.java 主要文件，邮件操作，发送

package main; 
 
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; 
 
  
 
public class MailOperation { 
 
    /** 
 
     * @author goming 
 
    *TODO:发送邮件 
 
    [email protected] user 
 
    [email protected] password 
 
    [email protected] host 
 
    [email protected] from 
 
    [email protected] to 
 
    [email protected] subject 
 
    [email protected] content 
 
    [email protected] 
 
    [email protected] 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"));//设置邮件内容 
 
              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 一个测试邮件"); 
 
              MimeBodyPart mbp1=new   MimeBodyPart();  //正文 
 
              mbp1.setContent(content,"text/html;charset=utf-8"); 
 
  
 
              Multipart mp=new MimeMultipart();   //整个邮件：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 = "[email protected]"; 
 
       String password = "xmG0ldenway"; 
 
       String host = "smtp.qq.com"; 
 
       String from = "[email protected]"; 
 
       String to = "[email protected]";//收件人 
 
       String subject = "Test"; 
 
       String content = "测试邮件"; 
 
       
 
       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 封装发件人账号密码

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 调用类，主要做邮件内容，以及发送一个地址回访！

/** 
 
     * 发送邮件 
 
     * @author goming 
 
     * @param to 
 
     * @param uuid 
 
     */ 
 
    @RequestMapping(params = "sendMail") 
 
    @ResponseBody 
 
    private void sendMail(String   to,HttpServletRequest request){ 
 
              MailOperation operation = new MailOperation(); 
 
       //发件人 
 
       String user = "[email protected]"; 
 
       String password = "******"; 
 
       String host = "smtp.qq.com"; 
 
       String from = "[email protected]"; 
 
       String subject = "感谢您注册创意生态资源集成系统软件"; 
 
       //邮箱内容 
 
       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：" 
 
                      + "<div style='width:950px;font-family:arial;'>为了您的账户安全，我们建议您点击以下链接验证邮箱：<br/><a href='"+basePath+"UserRegister.do?ValidateEmail&time="+longtimeLong+"&token="+to+"'>"+basePath+"UserRegister.do?ValidateEmail&time="+longtimeLong+"&token="+to+"</a><br/>请在24小时内点击该链接，您也可以将链接复制到浏览器地址栏访问。<br/>本邮件由系统自动发出，请勿回复。<br/>感谢您的使用。<br/>厦门交叉媒体科技有限公司</div>" 
 
                     +"</div>"); 
 
       try { 
 
           String res = operation.sendMail(user,   password, host, from, to, subject, sb.toString()); 
 
//         System.out.println(res); 
 
       } catch (Exception e) { 
 
           // TODO Auto-generated catch block 
 
           e.printStackTrace(); 
 
       } 
 
    }
