今天做词云，用的echarts，从网上巴拉的代码

在传数据的时候有很大的波折，因为layui要限制json数据的格式，然后echarts也要限制json的格式，整了好半天才把格式调教好

 protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        req.setCharacterEncoding("utf-8");
        resp.setCharacterEncoding("utf-8");
        String tempStr = req.getParameter("temp");
        System.out.println(tempStr);
        int temp = Integer.parseInt(tempStr);
//        System.out.println("ajax传值成功");
//        String data1="{"code":0,"msg":"","count":1000,"data":";
        PrintWriter out = resp.getWriter();
//        out.print(data1+ DaoUtil.getcount(temp)+"}");
//        System.out.println("提取值成功"+temp);
        String json = DaoUtil.getcount(temp);
        json = json.replaceAll("keyword", "name");
        json = json.replaceAll("count", "value");
        out.print(json);

        out.flush();
        out.close();
    }
