    Java認(rèn)證考試:Spring實(shí)現(xiàn)郵件發(fā)送

      Spring提供了一個(gè)發(fā)送郵件的抽象層,使發(fā)送郵件實(shí)現(xiàn)非常簡(jiǎn)單。下面代碼需要mail.jar包,如果服務(wù)器需要認(rèn)證,必須加入如下加粗代碼:

    Java認(rèn)證考試:Spring實(shí)現(xiàn)郵件發(fā)送

      源文件:SendMail.java:

      package mail;

      import org.springframework.mail.javamail.JavaMailSenderImpl;

      import org.springframework.mail.javamail.MimeMessageHelper;

      import javax.mail.internet.MimeMessage;

      import java.util.Properties;

      import java.util.Date;

      /**

      * @author chrischen

      */

      public class SendMail {

      //郵件發(fā)送器

      public static String Sender(String subject, String msg, String sendTo, String fromMail, String user, String pw, String fromName, String protocol, String host, String port){

      try{

      final String username = user;

      final String pass = pw;

      //需要認(rèn)證

      Properties props = new Properties();

      props.put(“mail.smtp.host”, host);

      props.put(“mail.smtp.auth”, “true”);

      props.put(“mail.transport.protocol”, protocol);

      props.put(“mail.from”, fromMail);

      //創(chuàng)建發(fā)送器

      JavaMailSenderImpl sender = new JavaMailSenderImpl();

      sender.setHost(host);

      sender.setUsername(username);

      sender.setPassword(pass);

      //創(chuàng)建消息

      MimeMessage message = sender.createMimeMessage();

      message.addHeader(“X-Mailer”, “Java Mailer”);

      MimeMessageHelper helper = new MimeMessageHelper(message);

      helper.setTo(sendTo);

      helper.setFrom(fromMail, fromName);

      helper.setSubject(subject);

      helper.setText(msg);

      helper.setSentDate(new Date());

      //開始發(fā)送

      sender.setJavaMailProperties(props);

      sender.send(message);

      }catch(Exception e){

      System.out.println(“Error:” + e);

      return “Failure”;

      }

      return “Success”;

      }

      //測(cè)試

      public static void main(String args[])throws Exception

      {

      String subject = “測(cè)試郵件”;//標(biāo)題

      String sendTo = “test@my.com”;//接收者郵件

      String fromMail = “send@my.com”;//發(fā)送者郵件

      String user = “send@my.com”;//發(fā)送者用戶

      String pw = “password”;//發(fā)送者郵件密碼

      String fromName = “Chen”;//發(fā)送者名字

      String protocol = “smtp”;//協(xié)議

      String host = “smtp.my.com”;//發(fā)送主機(jī)

      String port = “25”;//端口

      String msg = “簡(jiǎn)單郵件發(fā)送。”;//發(fā)送內(nèi)容

      String ret = Sender(subject, msg, sendTo, fromMail, user, pw, fromName, protocol, host, port);

      System.out.println(“郵件發(fā)送結(jié)果:” + ret);

      }

      }

      使用MimeMessageHelper,可以實(shí)現(xiàn)Multipart email,方便添加附件和內(nèi)嵌資源等。
