一，在项目中编写***.ftl文件
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>测试</title> </head> <body> ${date?string("yyyy")} </body> </html>
二，在servlet中使用freemarker
@WebServlet(name="test",urlPatterns="/test") public class servlet_test extends HttpServlet { private static final long serialVersionUID = 1L; private Configuration cfg; @Override public void init() throws ServletException { //initialize operation cfg=new Configuration(Configuration.VERSION_2_3_25); cfg.setServletContextForTemplateLoading(getServletContext(), "WEB-INF/ftl"); } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setCharacterEncoding("utf-8"); Map data=new HashMap(); data.put("date", new Date()); //得到模板 try { //将模板和数据结合，并返回浏览器 Template template=cfg.getTemplate("1test.ftl"); template.process(data, response.getWriter()); } catch (Exception e) { //e.printStackTrace(); response.getWriter().print("暂时无数据"); } } }
