解决控制台输出没问题，但前台传递乱码问题

private void ajaxWrite(HttpServletRequest request,HttpServletResponse response,String info) throws IOException{

// HttpServletResponse response = ServletActionContext.getResponse();
   request.setCharacterEncoding("UTF-8");
   //设置输出乱码问题
   response.setContentType("text/html;charset=UTF-8");
   response.setCharacterEncoding("UTF-8");

   //某些servlet版本setCharacterEncoding("UTF-8")有问题，通过charset=UFT-8解决

   PrintWriter out = response.getWriter();
   out.write(info);
   out.close();
}
