這篇文章主要為大家詳細(xì)介紹了JavaMail實(shí)現(xiàn)發(fā)送郵件功能，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了JavaMail實(shí)現(xiàn)發(fā)送郵件功能的具體代碼，供大家參考，具體內(nèi)容如下

用java發(fā)郵件，必須要導(dǎo)入新的包

mail.jar – 發(fā)郵件的核心包

activation.jar – 對(duì)用戶和密碼加密.

在mail.jar中有三個(gè)核心類：

Javax.mail.Session – 是指與郵件服務(wù)器會(huì)話。整個(gè)項(xiàng)目中只要一個(gè)就可以了.

Javax.mail.Message（接口） - 準(zhǔn)備發(fā)送數(shù)據(jù)信息。

MimeMessage －可以設(shè)置類型的數(shù)據(jù)信息。

Transport – 它擁有一個(gè)方法可以發(fā)送Message。

@Test
 public void sendMail() throws Exception{
  //1,聲明properties對(duì)象放信息
  Properties props = new Properties();
  //設(shè)置連接哪一臺(tái)服務(wù)器
  props.setProperty("mail.host", "smtp.163.com");
  //設(shè)置是否認(rèn)證：
  props.setProperty("mail.smtp.auth", "true");
  
  //2，聲明用戶名和密碼
  Authenticator auth = new Authenticator(){
   //返回用戶名和密碼對(duì)象
   @Override
   protected PasswordAuthentication getPasswordAuthentication() {
    PasswordAuthentication pa = new PasswordAuthentication("xxxxx@163.com", "123456");
    return pa;
   }
  };
  //3,獲取session對(duì)象
  Session session = Session.getDefaultInstance(props, auth);
  //設(shè)置session為調(diào)試模式
  session.setDebug(true);
  //4,聲明信息
  MimeMessage mm1 = new MimeMessage(session);
  //5,設(shè)置發(fā)件人信息
  Address form = new InternetAddress("xxxxx@163.com"); 
  mm1.setFrom(form);
  //6,設(shè)置收件人 ,RecipientType:發(fā)送，抄送，密送 類型
  mm1.setRecipient(RecipientType.TO, new InternetAddress("xxx@qq.com"));
  //mm1.setRecipient(RecipientType.CC, new InternetAddress(""));//抄送
 
  //7，設(shè)置主題
  mm1.setSubject("拉面學(xué)習(xí)通知");
  String cont = "請(qǐng)點(diǎn)擊 <a ;
  mm1.setContent(cont, "text/html;charset=UTF-8");
  
  //8，發(fā)送
  Transport.send(mm1);
 
 }

其中的mimeType可是text/plain純文本。

發(fā)送附件：

@Test
 public void sendMailWithFile() throws Exception{
 Properties ps = new Properties();
 ps.setProperty("mail.host", "smtp.163.com");
 ps.setProperty("mail.smtp.auth", "true");
 
 Authenticator auth = new Authenticator(){
  @Override
  protected PasswordAuthentication getPasswordAuthentication() {
  return new PasswordAuthentication("xxx@163.com","xxx.");
  } 
 };
 Session session = Session.getDefaultInstance(ps, auth);
 session.setDebug(true);
 MimeMessage msg = new MimeMessage(session);
 Address address = new InternetAddress("xxx@163.com");
 msg.setFrom(address);
 //發(fā)送給
 msg.setRecipient(RecipientType.TO, new InternetAddress("xxx@qq.com"));
 msg.setRecipient(RecipientType.BCC, new InternetAddress("xxx@qq.com"));//密送
 msg.setRecipient(RecipientType.CC, new InternetAddress("xxx@qq.com"));//抄送
 msg.setSubject("$激情小視頻*免費(fèi)觀看");
 
 //聲明多部件處理
 MimeMultipart mm = new MimeMultipart();
 
 MimeBodyPart body1 = new MimeBodyPart();
 //設(shè)置附件
 DataSource ds1 = new FileDataSource(new File("./img/a.jpg"));
 DataHandler dh1 = new DataHandler(ds1);
 body1.setDataHandler(dh1);
 //必須設(shè)置名稱
 body1.setFileName(MimeUtility.encodeText("美女.jpg"));
 
 MimeBodyPart body2 = new MimeBodyPart();
 DataSource ds2 = new FileDataSource(new File("./img/b.jpg"));
 DataHandler dh2 = new DataHandler(ds2);
 body2.setDataHandler(dh2);
 body2.setFileName(MimeUtility.encodeText("美女2.jpg"));
 
 MimeBodyPart body3 = new MimeBodyPart();
 DataSource ds3 = new FileDataSource(new File("./img/m.mp3"));
 DataHandler dh3 = new DataHandler(ds3);
 body3.setDataHandler(dh3);
 body3.setFileName(MimeUtility.encodeText("小電影.mp3"));

 //添加body到mm
 mm.addBodyPart(body1);
 mm.addBodyPart(body2);
 mm.addBodyPart(body3);
 
 msg.setContent(mm);

 //設(shè)置發(fā)送日期
 Calendar c = Calendar.getInstance();
 c.add(Calendar.DATE, -5);
 msg.setSentDate(c.getTime());

 //發(fā)送
 Transport.send(msg);
 }
