        //附件
        mimeMessageHelper.addAttachment("1.jpg",new File("D:\\background.jpg"));
        mimeMessageHelper.addAttachment("2.jpg",new File("D:\\background.jpg"));

        mimeMessageHelper.setFrom("482475181@qq.com");//接受发送过来的邮件
        javaMailSender.send(mimeMessage);
    }
    //可以进行再次封装
}
