Servlet集成

只需要在Servlet代码里引用ServletGroupTemplate就能集成Beetl，他提供了一个render(String child, HttpServletRequest request, HttpServletResponse response)方法。例子如下：

  1. protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {
  2.     response.setContentType("text/html;charset=UTF-8");
  3.     //模板直接访问users
  4.     request.setAttribute("users",service.getUsers());
  5.     ServletGroupTemplate.instance().render("/index.html", request, response);
  6. }

ServletGroupTemplate同其他web集成一样，将读取配置文件来配置，如果需要通过代码配置，可以在Servlet listener里 ServletGroupTemplate.instance().getGroupTemplate()方法获取GroupTemplate
