JavaMail
需要的Java包
mail.jar
activation.jar
核心类：
Session服务器连接对象
得到Session对象：Session.getInstance(Proporties,Authenticator)
设置属性mail.host,mail.stmp.path：Properits.setProperity()
得到Authenticator：
Authenticator auth = new Authenticator(){
   protected PasswordAuthentication getPasswordAuthentication(){
       return new PasswordAuthentication("name","password");
   }
}
Session session=Session.getInstance(Proporties,Authenticator);
MimeMessage邮件对象
MimeMessage msg = new MimeMessage(session);
-setFrom()，设置发件人、设置收件人，设置正文
setFrom(new InternetAddress("发件人"))：设置发件人
setRecipients(RecipientType.TO/CC/BCC,收件人)：设置收件人，抄送，暗送
setSubject(String);设置主题
setContent(String,Sting);设置主题
Transport
-send(MimeMessage)

不要忘记先去邮箱打开SMTP服务

发送纯文本：

public void fun() throws Exception{//得到Session对象Properties props = new Properties();props.setProperty("mail.host", "smtp.163.com");props.setProperty("mail.smtp.auth", "true");Authenticator auth = new Authenticator(){@Overrideprotected  PasswordAuthentication getPasswordAuthentication(){return new PasswordAuthentication("账号","密码");}};Session session =Session.getDefaultInstance(props,auth);//创建MimeMessageMimeMessage msg = new MimeMessage(session);msg.setFrom(new InternetAddress("xxx"));//设置发件人msg.setRecipients(RecipientType.TO, "收件人邮箱");msg.setSubject("Test Email");//设置主题msg.setContent("This is a Test Email","text/html;charset=utf-8");//设置内容//发送Transport.send(msg);}

发送文件：

public void fun() throws Exception{//得到Session对象Properties props = new Properties();props.setProperty("mail.host", "smtp.163.com");props.setProperty("mail.smtp.auth", "true");Authenticator auth = new Authenticator(){@Overrideprotected  PasswordAuthentication getPasswordAuthentication(){return new PasswordAuthentication("账号","密码");}};Session session =Session.getDefaultInstance(props,auth);//创建MimeMessageMimeMessage msg = new MimeMessage(session);msg.setFrom(new InternetAddress("Xxx"));//设置发件人msg.setRecipients(RecipientType.TO, "收件人邮箱");msg.setSubject("Test Email");//设置主题//设置多部件的部件内容MimeMultipart list = new MimeMultipart();//创建多部件内容MimeBodyPart part1 = new MimeBodyPart();//创建单个部件part1.setContent("This is a Test Message", "text/html;charset=utf-8");//设置内容list.addBodyPart(part1);//加入多部件中MimeBodyPart part2 = new MimeBodyPart();part2.attachFile(new File("E:/Picture/12809803194626.jpg"));part2.setFileName(MimeUtility.encodeText("picture.jpg"));list.addBodyPart(part2);//设置到邮件内容msg.setContent(list);//发送Transport.send(msg);}}
