本文通过实现一个简单的FreeMarker模板示例来解释如何将Java数据传递到模板中，并展示如何在模板中使用循环来显示列表数据。

helloworld.ftl

FreeMarker Template example: ${message}  

=======================
===  County List   ====
=======================
<#list countries as c>
	${c_index + 1}. ${c}
</#list>

public class FTLHelloWorld {
	
	public static void main(String[] args) {

		Configuration cfg = new Configuration();
		try {
			
			Template template = cfg.getTemplate("src/helloworld.ftl");
			
			// Build the data-model
			Map<String, Object> data = new HashMap<String, Object>();
			data.put("message", "Hello World!");

			//List parsing 
			List<String> countries = new ArrayList<String>();
			countries.add("India");
			countries.add("United States");
			countries.add("Germany");
			countries.add("France");
			
			data.put("countries", countries);

			
			// Console output
			Writer out = new OutputStreamWriter(System.out);
			template.process(data, out);
			out.flush();

			// File output
			Writer file = new FileWriter (new File("C:\\FTL_helloworld.txt"));
			template.process(data, file);
			file.flush();
			file.close();
			
			
			
		} catch (IOException e) {
			e.printStackTrace();
		} catch (TemplateException e) {
			e.printStackTrace();
		}
	}
}

输出：

FreeMarker Template example: Hello World!

=======================
=== County List ====
=======================
1. India
2. United States
3. Germany
4. France

Thus note how we passed data from Java to FTL and the same get painted. The ${message} got replaced with the message that we populated in Java. Also notice how we passed a country List<String> through Java and inside FTL we used <#list> </#list> to display its values.
