服务于ajax的控制器方法

此方法用jsp内置对象out输出到xml文件中
public void ajaxEditorList() throws IOException{
  HttpServletResponse response = ServletActionContext.getResponse();
  //System.out.println("ddddddddddddddddddddddd;;;");
  int unitid=Integer.parseInt(request.getParameter("unitid"));
  //System.out.println("unitid:"+unitid);
  response.setHeader("Pragma", "No-cache");
  response.setHeader("Cache-Control", "no-cache");
  response.setDateHeader("Expires", 0);
  
  request.setCharacterEncoding("GBK");
  response.setCharacterEncoding("GBK");
  unitinfolist=adminUnitInfoService.getKangarooUnitinfoListByunitid(unitid);
  response.setContentType("text/xml");
  PrintWriter out = response.getWriter();
  out.print("<?xml version=\"1.0\" encoding=\"GBK\"?>");
  out.print("<unitinfoes>");
  if(unitinfolist==null||unitinfolist.isEmpty()){
   out.print("<isempty>");
   out.print("true");
   out.print("</isempty>");
  }else{
   out.print("<isempty>");
   out.print("false");
   out.print("</isempty>");
   for(KangarooUnitinfo ui:unitinfolist){
    out.print("<unitinfo unitinfoid=\""+ui.getInfoid()+"\">");
    out.print("<unitid>"+ui.getUnitid()+"</unitid>");
    out.print("<title>"+ui.getTitle()+"</title>");
    out.print("</unitinfo>");
   }
  }
  out.print("</unitinfoes>");
  out.flush();
  out.close();
 }
