字符串作为freemarker模板的简单实现例子

package com.test.demo;

import java.io.IOException;
import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;

import freemarker.cache.StringTemplateLoader;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateException;

public class TestFreemarker {

/**
* @param args
*/
public static void main(String[] args) {

Configuration cfg = new Configuration();
StringTemplateLoader stringLoader = new StringTemplateLoader();
String templateContent="欢迎：${name}";
stringLoader.putTemplate("myTemplate",templateContent);

cfg.setTemplateLoader(stringLoader);

try {
Template template = cfg.getTemplate("myTemplate","utf-8");
Map root = new HashMap();
root.put("name", "javaboy2012");

StringWriter writer = new StringWriter();
try {
template.process(root, writer);
System.out.println(writer.toString());
} catch (TemplateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
