javax.mail
mail

代码：
public class SendMailUtil {
public static void main(String[] args) {
// 收件人电子邮箱
String to = "pangbin0502@qq.com";

    // 发件人电子邮箱
    String from = "pangbin0502@163.com";

    // 指定发送邮件的主机为 smtp.qq.com
    //163 邮件服务器
    String host = "smtp.163.com";
    //收件人(多个)
    String[] TOS = new String[]{"pangbin0502@qq.com"};

    // 获取系统属性
    Properties properties = System.getProperties();

    // 设置邮件服务器
    properties.setProperty("mail.smtp.host", host);

    properties.put("mail.smtp.auth", "true");
    // 获取默认session对象
    Session session = Session.getDefaultInstance(properties, new Authenticator() {
        @Override
        public PasswordAuthentication getPasswordAuthentication() {
            //发件人邮件用户名、授权码
            return new PasswordAuthentication("pangbin0502@163.com", "163授权码");
        }
    });

    try {
        // 创建默认的 MimeMessage 对象
        MimeMessage message = new MimeMessage(session);

        // Set From: 头部头字段
        message.setFrom(new InternetAddress(from));

        // Set To: 头部头字段
        /*message.addRecipient(Message.RecipientType.TO,
                new InternetAddress(to));*/

        // 加载收件人地址
        InternetAddress[] sendTo = new InternetAddress[TOS.length];
        for (int i = 0; i < TOS.length; i++) {
            sendTo[i] = new InternetAddress(TOS[i]);
        }
        message.addRecipients(Message.RecipientType.TO, sendTo);
        //为防止5开头报错，先给自己发一份
        message.addRecipients(MimeMessage.RecipientType.CC, InternetAddress.parse(from));

        // Set Subject: 头部头字段
        message.setSubject("This is the Subject Line!");

        // 设置消息体
        message.setText("This is actual message");

        // 发送消息
        Transport.send(message);
        System.out.println("Sent message successfully....from runoob.com");
    } catch (MessagingException mex) {
        mex.printStackTrace();
    }
}

}
