freemarker加载模板文件的三种方法

Configuration cfg= new Configuration();        
freemarkerCfg.setClassForTemplateLoading(this.getClass(), "/");//类路径

//cfg.setDirectoryForTemplateLoading(new File(System .getProperty("user.dir") + "\\template"));//决对路径

//cfg.setServletContextForTemplateLoading(getServletContext(),"/templates");//web路径
cfg.setEncoding(Locale.getDefault(), "UTF-8");
Template template = null ;        

Locale.setDefault(Locale.ENGLISH);
try{            
        template = cfg.getTemplate("Hello.txt");
        template.setEncoding("UTF-8");
        HashMap root = newHashMap();
        map.put("user", name);
        Writer out = new StringWriter();
        Writer out = new OutputStreamWriter(System.out);
        Writer outr = new PrintWriter(new BufferedWriter(new FileWriter("d:/liyong.txt")));
        template.process(map, out);
        System.out.println(out.toString());
}catch(Exception e){
      e.printStackTrace();
}
