如何解析freemarker模板的以下结构？

Question

I have some problem with following:

someMethod(List recipients, String message) {

        SimpleHash model = new SimpleHash();
        model.put("message", message);

        for (String email : recipients) {
            model.put("name", email);
            String buildHTML = FreeMarkerTemplateUtils
                    .processTemplateIntoString(freemarkerConfiguration
                            .getTemplate("customMail.ftl", locale, "UTF-8"), model);
            model.remove("name");
            create(buildHTML, email);
        }
}

That's ok! but parameter "message" has similar to the following:

Hi, ${userName}!

Therefore, how to recognize

${userName}

if it's exist in message?

And my template:

<h1>
  <td id="message">
    ${message}
  </td>
</h1>

If I understand it well, you are saying that message itself is a small template. In that case, you could use <@message?interpret /> , where ?interpret will parse message as template content, and then <@.../> will invoke it.
