(JAVA)寫檔案並直接下載(txt)

        try {
            SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd_HH_mm");
            String filename = sf.format(new Date()).toString() + "_Export.txt";

//可直接下載檔案
          String filepath = filename;
            response.reset();
            response.setContentType("application/octet-stream");
            String fileName = URLDecoder.decode(filepath, "utf-8");
            java.net.URLEncoder.encode(fileName, "utf-8");
            //response.addHeader("Content-Disposition", "attachment;" + "filename=\"" + URLEncoder.encode(fileName, "utf-8") + "\"");
            response.setHeader("Content-Disposition", "attachment;filename=" + filename);
