        Properties props = new Properties();// key=value

        props.setProperty("mail.transport.protocol", "smtp");// JavaMail规范指定的
        props.setProperty("mail.host", "smtp.qq.com");// JavaMail规范指定的
        props.setProperty("mail.smtp.auth", "true");// （需要身份认证，如果不认证，不能发送邮件）与具体的JavaMail的实现有关(此处用的SUN提供的参考实现)

        Session session = Session.getInstance(props);// 发邮件的一些环境
        MimeMessage message = new MimeMessage(session);

        message.setFrom(new InternetAddress("958904120@qq.com"));// 设置发件人
        message.setRecipients(Message.RecipientType.TO, "weizhen.lv@qq.com");// 设置收件人以及发送的类型

        message.setContent("woailiulv", "text/plain");// 邮件中的数据类型用的MIME类型

        message.saveChanges();
        // 发送邮件
        Transport ts = session.getTransport();
