Question

是否可以在ftl中命名一些块并在java端获取它们？例如，使用不正确的语法可能

#emailSubject[
This is email subject]
#emailMessage
[Email multi-
line message!!
Hi all]

和java方面看起来像

template.process("template.ftl", resultModelOrSomethingElse);
String emailSubject = resultModelOrSomethingElse.getEmailSubject();
String emailMessag = resultModelOrSomethingElse.getEmailMessage();

开箱即用，你可以这样做：

<#assign emailSubject>This is the email subject</#assign>

<#assign emailMessage>
  This is the email message...
</#assign>

然后：

// Same as template.process, but you will have the Environment:
Environment env = template.createProcessingEnvironment(dataModel, out);
env.process();

// Extract top-level variables:
TemplateModel emailSubject = env.getVariable("emailSubject");
TemplateModel emailMessage = env.getVariable("emailMessage");

（如果你会做很多事情，你可能想在模板中简化这一点。像<@emailSubject>This is the email subject</@>更简洁，更加万无一失，因为如果有人犯了错误，它会立即失败。 “emailSubject”变量名称。）
