        PrintWriter out = response.getWriter();
        response.setContentType("text/html;charset=UTF-8");
        response.setCharacterEncoding("UTF-8");
        request.setCharacterEncoding("UTF-8");
        response.setHeader("content-type","text/html;charset=UTF-8");
        //以下语句无法解决问题，位置不对
        //out.write("<meta http-equiv=/"Content-Type/" content=/"text/html; charset=UTF-8/">/r/n");
