using freemarker and spring to construct templates
I am new to freemarker. I have a spring application that I am planning to use with freemarker. Templates will be stored in database and based on the login, I want to retrieve the template from database. Can any one tell me how to configure the freemarker in spring and get the html tags as a string after constructing the template.开发者_StackOverflow中文版 I did googling but I could not understand much.
I tried till this level. In spring I have done till this level. Finally I want html tags in a string.
// Spring freemarker specific code
Configuration configuration = freemarkerConfig.getConfiguration();
StringTemplateLoader stringTemplateLoader = new StringTemplateLoader();
// My application specific code
String temp = tempLoader.getTemplateForCurrentLogin();
Thanks.
To tie together the bits of code you posted, you can do something like this:
// you already have this bit
String templateText = tempLoader.getTemplateForCurrentLogin();
// now programmatically instantiate a template
Template t = new Template("t", new StringReader(templateText), new Configuration());
// now use the Spring utility class to process it into a string
// myData is your data model
String output = FreeMarkerTemplateUtils.processTemplateIntoString(template, myData);
This java method will process the freemarker template and will give html tags as String after constructing the template.
public static String processFreemarkerTemplate(String fileName) {
StringWriter stringWriter = new StringWriter();
Map<String, Object> objectMap = new HashMap<>();
Configuration cfg = new Configuration(Configuration.VERSION_2_3_24);
try {
cfg.setDirectoryForTemplateLoading(new File("path/of/freemarker/template"));
cfg.setDefaultEncoding("UTF-8");
cfg.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER);
cfg.setLogTemplateExceptions(false);
Template template = cfg.getTemplate(fileName);
template.process(objectMap, stringWriter);
} catch (IOException | TemplateException e) {
e.printStackTrace();
} finally {
if (stringWriter != null) {
try {
stringWriter.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return stringWriter.toString();
}
