     protected void service(HttpServletRequest request, 
             HttpServletResponse response) throws ServletException, IOException {
 
         response.setContentType("text/html;charset=utf-8");//--------------设置响应类型及编码格式
         PrintWriter out = response.getWriter();//--------------------------获取response输出流
         
         Date now = new Date();//-------------------------------------------获取系统时间
         SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd");//--------设置时间格式
         
         out.println(sf.format(now));//-------------------------------------格式化并输出时间
         out.close();//-----------------------------------------------------关闭流
         
         
     }
