// 1. Configure FreeMarker
//
// You should do this ONLY ONCE, when your application starts,
// then reuse the same Configuration object elsewhere.
Configuration cfg = new Configuration();
// Where do we load the templates from:
cfg.setClassForTemplateLoading(MainTest.class, "templates");
// Some other recommended settings:
cfg.setIncompatibleImprovements(new Version(2, 3, 20));
cfg.setDefaultEncoding("UTF-8");
cfg.setLocale(Locale.US);
cfg.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER);
// 2. Proccess template(s)
//
// You will do this for several times in typical applications.
// 2.1. Prepare the template input:
Map<String, Object> input = new HashMap<String, Object>();
input.put("title", "Vogella example");
input.put("exampleObject", new ValueExampleObject("Java object", "me"));
List<ValueExampleObject> systems = new ArrayList<ValueExampleObject>();
systems.add(new ValueExampleObject("Android", "Google"));
systems.add(new ValueExampleObject("iOS States", "Apple"));
systems.add(new ValueExampleObject("Ubuntu", "Canonical"));
systems.add(new ValueExampleObject("Windows7", "Microsoft"));
input.put("systems", systems);
// 2.2. Get the template
Template template = cfg.getTemplate("helloworld.ftl");
// 2.3. Generate the output
// Write output to the console
Writer consoleWriter = new OutputStreamWriter(System.out);
template.process(input, consoleWriter);
// For the sake of example, also write output into a file:
Writer fileWriter = new FileWriter(new File("output.html"));
try {
template.process(input, fileWriter);
} finally {
fileWriter.close();
}
