SpringBoot-Thymeleaf发送模板带附件邮件

自个学习笔记不喜勿喷

@RunWith(SpringRunner.class)@SpringBootTestpublic class SpringBootEmailApplicationTests {    @Value("${spring.mail.username}")    private String fromEmailAddr;    @Autowired    private JavaMailSender javaMailSender;    @Autowired    private TemplateEngine templateEngine;    /**     * @throws MessagingException      * @Title: sendHtmlEmail     * @Description: 发送thymeleaf模板邮件     * @return void     * @throws     */    @Test    public void sendHtmlEmail() throws MessagingException {        MimeMessage mailMessage = javaMailSender.createMimeMessage();        //开启带附件true        MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true);        IContext context = new Context();        //获取模板html代码        String process = templateEngine.process("index", context);        try {            messageHelper.setFrom(fromEmailAddr);            messageHelper.setTo("[e-mail]");            messageHelper.setSubject("SpringBootThymeleaf模板邮件");            messageHelper.setText(process, true);            FileSystemResource avatar = new FileSystemResource(                    new File("F:\\workspace\\SpringBootEmail\\src\\main\\resources\\templates\\img\\bappy.jpg"));            //<img src="cid:avatar" />            messageHelper.addInline("avatar", avatar);        } catch (MessagingException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        javaMailSender.send(mailMessage);    }}

有一个问题，那就是不能发送外嵌样式的邮件，只能将样式弄进模板文件里。
