测试代码：

    @Autowired
    private JavaMailSender javaMailSender;
    @Value("${spring.mail.username}")
    private String from;

    @Test
    public void sendSimpleMail() {
        MimeMessage message = null;
        try {
            message = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(from);
            helper.setTo("[email protected]");
            helper.setSubject("标题：发送Html内容");
            StringBuffer sb = new StringBuffer();
            sb.append("<h1>大标题-h1</h1>")
                    .append("<p style='color:#F00'>Hello,Wrold;</p>");
            helper.setText(sb.toString(), true);
            javaMailSender.send(message);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
