一个freemarker生成文件的简单例子

	private void exportByFreemarker() {
		Configuration cfg = new Configuration();
//		try {
//			cfg.setDirectoryForTemplateLoading(new File("F:/ftl"));
//		} catch (IOException e) {
//			System.out.println("template not found!");
//			e.printStackTrace();
//		}
		cfg.setClassForTemplateLoading(this.getClass(), "ftl");
		cfg.setObjectWrapper(new DefaultObjectWrapper());

		Map root = new HashMap();
		root.put("time", new Date().toString());

		try {
			Template templateHtml = cfg.getTemplate("template filename");

			// Writer out = new OutputStreamWriter(System.out);
			Writer outHtml = new FileWriter(new File("new file path"));

			templateHtml.process(root, outHtml);
			outHtml.flush();
			outHtml.close();
		} catch (IOException e) {
			System.out.println("error to read template file");
			e.printStackTrace();
		} catch (TemplateException e) {
			System.out.println("creat file error");
		}

		System.out.println("[info] Done! ");
