java实现发送邮件

在工作中遇到了java发送邮件提醒的需求，下面记录一下这次的开发代码。

 public static void sendEmail(String someone, String subject, String content) {
            Properties props = new Properties();
            props.setProperty("mail.host", "smtp.aliyun.com");  //这里是邮箱发件人的配置
            props.setProperty("mail.smtp.auth", "true");

            Authenticator authenticator = new Authenticator() {
            @Override
            public PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("zhangzhiyongali@aliyun.com", "password");  //邮箱发件人的账号密码
             }
        };
            Session session = Session.getDefaultInstance(props, authenticator);
            session.setDebug(true);
            Message message = new MimeMessage(session);
            try {
            message.setFrom(new InternetAddress("zhangzhiyongali@aliyun.com"));
            message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(someone));
            //message.setRecipients(RecipientType.TO,InternetAddress.parse("测试的接收的邮件多个以逗号隔开"));
            try {
            message.setSubject(subject);
            message.setContent(content, "text/html;charset=UTF-8");
            Transport.send(message);

            } catch (Exception e) {
            e.printStackTrace();
            }
            } catch (AddressException e) {
            e.printStackTrace();
            } catch (MessagingException e) {
            e.printStackTrace();
            }

    }


    public static void main(String[] args) {
    //支持群发
        sendEmail("zhangjingceshi@umi-game.cn,群发将收件人地址用逗号隔开即可","邮件的标题","测试邮件发送");
        System.out.println("发送完成！");

    }
