本文提供了一个使用Java发送邮件的示例代码，包括配置SMTP服务器、身份验证等步骤，并展示了如何通过MimeMessage构建邮件内容。

import java.util.Date;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.PasswordAuthentication;
import javax.mail.SendFailedException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class MySecondMail {
Session session = null;

String mailUser = "ahler2003";

String host = "smtp.263.net";

String pwd = "mnkmjv10";

public MySecondMail() {
init();
}

public void init() {
  Properties props = new Properties();
  props.put("mail.transpost.protocol", "smtp");
  props.put("mail.smtp.host", "smtp.263.net");
  props.put("mail.smtp.auth", "true");
  props.put("mail.smpt.port", "25");
  Autherticatorbean auth = new Autherticatorbean(mailUser, pwd);
  // session认证
  session = Session.getInstance(props, auth);
  // 这个是跟踪后台消息。打印在控制台
  session.setDebug(true);
}

public static void main(String[] args) {
new MySecondMail().sendMails();
System.out.println("send mail success!");
}

public void sendMails() {
  try {
   Message msg = new MimeMessage(session);
   msg.setFrom(new InternetAddress("ahler2003@263.net"));
   msg.setRecipients(Message.RecipientType.TO, InternetAddress
     .parse("ahler2003@263.net"));
   //msg.setRecipients(Message.RecipientType.BCC, InternetAddress
   //  .parse("ahler2003@263.net"));
   msg.setSentDate(new Date());
   msg.setSubject("测试邮件");
   msg.setContent("this is my mail", "text/html");
   msg.setText("我成功了。哈哈");

   //Transport transport = session.getTransport("smtp");
   //transport.connect(host, mailUser, pwd);
   Transport.send(msg);
  } catch (SendFailedException e) {
   e.printStackTrace();
  } catch (Exception ee) {
   ee.printStackTrace();
  }

}
}
