@Resource
private MailProperties mailProperties;
@Resource
JavaMailSender javaMailSender;
@Resource
private HttpServletRequest request;
@Resource
private HttpServletResponse response;


   /**
     * 发生邮件
     * @param email 邮箱
     * @param contentKey 模板配置文件中配置
     * @param paras 参数
     */
    private void sendEmail(String email, String contentKey, Map paras) {
        SimpleMailMessage message = new SimpleMailMessage();

        message.setTo(email);
        message.setFrom(mailProperties.getUsername());
        message.setSubject(mailProperties.getProperties().get(contentKey + ".subject"));

        String text = mailProperties.getProperties().get(contentKey + ".text");
        if (text != null) {
            for (String key : paras.keySet()) {
                text = text.replace(String.format("${%s}", key), paras.get(key));
            }
            message.setText(text);
        }
        try {
            javaMailSender.send(message);
        } catch (MailException e) {
            throw new AdminException(e, ErrorCode.ADMIN_CREATE_MAIL_SEND_FAIL);
