[英]Write freemarker template to String output
I would like to have freemarker template output in String. 我想在String中有freemarker模板输出。 I have a freemarker template file commonTemplate.ftl .
我有一个freemarker模板文件commonTemplate.ftl 。
<div>
<div>
<h1>${userDetails.name}</h1>
${userDetails.birthday} ${userDetails.id}
</div>
</div>
And Java code which populates model and prints output to console App.java . 和Java代码填充模型并将输出打印到控制台App.java 。
public class App {
private Service service = new Service();
public void execute() {
Configuration configuration = prepareConfiguration();
// Load templates from resources/templatess.
configuration.setClassForTemplateLoading(App.class, "/templates");
try {
Template template = configuration.getTemplate("commonTemplate.ftl");
// Console output
Writer out = new OutputStreamWriter(System.out);
template.process(prepareData(), out);
out.flush();
} catch (IOException | TemplateException e) {
throw new RuntimeException(e);
}
}
private Configuration prepareConfiguration() {
Configuration configuration = new Configuration(Configuration.VERSION_2_3_23);
configuration.setDefaultEncoding("UTF-8");
configuration.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER);
configuration.setLogTemplateExceptions(false);
return configuration;
}
private Map<String, Object> prepareData() {
Model model = service.getModel();
Map<String, Object> data = new HashMap<String, Object>();
data.put("userDetails", model.getUserDetails());
return data;
}
}
It works for console output. 它适用于控制台输出。
<div>
<div>
<h1>john Doe</h1>
1990-01-10T12:11+01:00[Europe/Prague] 1
</div>
</div>
Hope this works. 希望这有效。
// write the freemarker output to a StringWriter
StringWriter stringWriter = new StringWriter();
template.process(prepareData(), stringWriter);
// get the String from the StringWriter
String string = stringWriter.toString();
try {
Template template = configuration.getTemplate("commonTemplate.ftl");
Writer out = new StringWriter();
template.process(prepareData(), out);
System.out.println(out.toString());
} catch (IOException | TemplateException e) {
throw new RuntimeException(e);
}
