How to pass String as input in FreeMarker?
提问by Shashi
All the templates are stored in database. And i have to fetch contents of a template from database and marked up with freemarker. The end output will be rendered in a textbox.
所有模板都存储在数据库中。我必须从数据库中获取模板的内容并用 freemarker 标记。最终输出将呈现在文本框中。
But, i am not finding any methodology by which i can send string instead of file name.
但是，我没有找到任何可以发送字符串而不是文件名的方法。
Please suggest.
请建议。

You can pass your template to the Templateconstructor with a StringReader:
您可以使用StringReader将模板传递给模板构造函数：
// Get your template as a String from the DB
String template = getTemplateFromDatabase();
Map<String, Object> model = getModel();
Configuration cfg = new Configuration();
cfg.setObjectWrapper(new DefaultObjectWrapper());
Template t = new Template("templateName", new StringReader(template), cfg);
Writer out = new StringWriter();
t.process(model, out);
String transformedTemplate = out.toString();
