关于CSV格式下载失败的问题

[木木木_2016]

如图，生成CSV一切正常，就是下载失败，使用a标签下载也是失败，其他后缀的都没有问题
生成CSV文件代码

StringBuffer buf = new StringBuffer();

            String[] colNamesArr = null;
            String[] mapKeyArr = null;

            colNamesArr = colNames.split(",");
            mapKeyArr = mapKey.split(",");

            // 完成数据csv文件的封装
            // 输出列头
            for (int i = 0; i < colNamesArr.length; i++) {
                buf.append(colNamesArr[i]).append(CSV_COLUMN_SEPARATOR);
            }
            buf.append(CSV_RN);

            if (null != dataList) { // 输出数据
                for (int i = 0; i < dataList.size(); i++) {
                    for (int j = 0; j < mapKeyArr.length; j++) {
                        buf.append(dataList.get(i).get(mapKeyArr[j])).append(CSV_COLUMN_SEPARATOR);
                    }
                    buf.append(CSV_RN);
                }
            }
            // 写出响应
            os.write(buf.toString().getBytes("GBK"));
            os.flush();
            return true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return false;
 

下载代码

 FileInputStream in = null;
        OutputStream out = response.getOutputStream();
        byte[] buffer = new byte[1024];
        int len = 0;
//        response.setContentType("text/csv;charset=utf-8");
        response.setContentType("application/x-msdownload");
        response.setHeader("Content-Disposition", "attachment;filename="
                + URLEncoder.encode(title, "utf-8"));
//        response.setCharacterEncoding("utf-8");
        //URLEncoder.encode(fileName, "GBK")
        try {
            in = new FileInputStream(path);
            while ((len = in.read(buffer)) > 0) {
                out.write(buffer, 0, len);
            }
        } catch (IOException e) {
            e.printStackTrace();
         }finally {
            if (in != null) {
                try {
                    in.close();
                    out.close();
                } catch (Exception e) {
                    throw new RuntimeException(e);
                }
            }
        }
